As shown in Figure 3 and Figure 4, heating plate 100 is overall curved, be that hollow out 130(is blank in the middle part of the main body of its string configuration) part, what be connected with hollow out 130 is opening 140, two ends (i.e. the open end 150 and 160) place of opening 140 is provided with the connecting bore 171 and 172 being connected induction heating power the two poles of the earth, when being connected by connecting bore 171 and 172 and external power supply, whole heating plate 100 is separated through hollow out 130 and opening 140, in substance form a current return from open end 150 to plate face 110 again to plate face 120 finally to open end 160; Wherein, the plate face 110 and 120 at two ends is in vertical bar shaped, its trend moves towards basically identical with paper web 200, about 3 times of the width in the width in plate face 110 the chances are plate face 120, plate face 120 is corresponding near the side on packaging material limit 210 with paper web 200, and unlimited near to realize the high-frequency heating to it, plate face 120 relative to the distance of paper web 200, plate face 110 is wanted far (as shown in Figure 2).
Plate face 110 offers knock hole 180, through being connected and fixed of screw 181, heating plate 100 is fixed on support 300, connects as one further after being connected and fixed of connecting panel 310 and support 320 etc. with dowel disc 500.As shown in Figure 2, the side of dowel disc 500 is provided with a L shape connecting panel, and side plate face (side panel that the vertical plane namely in Fig. 2 is illustrated) connecting bore 640 on the slide block 600 shown in the links such as screw and Fig. 5 and Fig. 6 of this L shape connecting panel is connected and fixed; And then make when slide block 600 slides up and down displacement, drive dowel disc 500 and the running roller 510 of locating thereon and heating plate 100 etc. to be also shifted up and down thereupon.
Its middle slide plate 600 is limited in one group of both sides can between the roller 630 of flexible rotating, as shown in Figure 5 and Figure 6, two rollers 630 are respectively arranged in the left and right of slide plate 600, and the roller 630 that the both sides of slide plate 600 are provided with annular groove is spacing, and four rolling is spacing and lead to its both sides.Two rollers 630 on the left of slide plate 600 are positioned on stay bearing plate 660 through pivot shaft 610 respectively, and two rollers 630 on right side are positioned on stay bearing plate 660 through pivot shaft 620 respectively, and wherein pivot shaft 620 is eccentric shaft.
As shown in Figure 7 and Figure 8, pivot shaft 620 is stepped shaft, it comprises three sections of axle rank 621,622 and 623 that the diameter of axle becomes large gradually, match with the knock hole that stay bearing plate 660 is offered in axle rank 621, match with the endoporus of roller 630 in axle rank 622, roller 630 after positioning vertically by axle rank 623 and stay bearing plate 660 institute spacing.The axis on axle rank 621 is the O1 in figure, the axis on axle rank 622 and 623 is the O2 in figure, two axial lines O1 and O2 does not overlap, two pivot shafts 620 can drive arrangement roller 630 thereon to carry out eccentric rotary around its orientation axis simultaneously, the position on roller 630 can be obtained circle that an eccentric throw is radius.Like this, the control that can realize slide plate 600 right position by the position of axes O 2 of the eccentric shaft (pivot shaft 620) on adjustment right side when double swerve appears in slide plate 600, can certainly occur adopting this structure to realize compensation when wearing and tearing in slide plate 600 left and right edges.Axle rank 623 define one section of shaft shoulder step or limited step, and its cross section can be circular, square, oval or hexagon.Axle rank 621 are provided with one section for coordinating the thread segment of rear compression pivot shaft 620 and stay bearing plate 660, pressure can be applied to cooperation section by the nut being mated installation, thus make pivot shaft 620 be fastened on stay bearing plate 660, substantially increase the rigidity of installing rear support axle 620, effective prevention can be rocked without impaction state lower shaft, affects the state of working stability.Consider and coordinate section to be round section, pivot shaft 620 also needs arrange the stop section of one end for preventing pivot shaft 620 from self rotating when screwing the nut on linkage section, the afterbody hexagonal rib such as, coordinated with spanner when tightening, certain stop section cross section also can be the shapes such as square, ellipse or the groove containing counterbore.
During concrete operations, be that the gap driving the roller 630 be placed on its eccentric shaft part (i.e. axle rank 622) right side edge that is close or that leave slide plate 600 to realize in the side of slide plate 600 and the groove fit process of roller 630 by rotating two pivot shafts 620 adjusts, pivot shaft 620 tightens together with stay bearing plate 660 by the screw thread (i.e. the screw thread of stay bearing plate 660 opposite side on pivot shaft afterbody axle rank 621) being placed in linkage section on pivot shaft 620 that utilizes behind suitable gap to be adjusted.And very little due to the clearance control between roller 630 and slide plate 600, significantly rock so adjusted in the process that tail skid 600 slidably reciprocates not have.
Pivot shaft 610 on the left of slide plate 600 also adopts the stepped shaft structure identical with pivot shaft 620, but does not have eccentric shaft part, and it is placed in row's connecting bore of stay bearing plate 660, and then directly fastening, the roller 630 on it can flexible rotating, but can not adjust position.Certainly it also can be arranged to the eccentric shaft structure of similar opposite side pivot shaft 620 as required.
The both sides of stay bearing plate 660 are provided with two registration holes 661, by fixing screw 662(bolt) and be such as the wallboard of bottle placer through back-up block 670 and adapter plate 680() be connected and fixed; This kind of connection mode makes pivot shaft 620 and 610 namely realize location by means of only a stay bearing plate 660, avoids and adopts multiple parallel stay bearing plate to carry out requirement on machining accuracy higher to stay bearing plate parallelism and knock hole concentricity etc. when frame-type is fixed and the difficulty of processing that brings and frame welding are out of shape the difficulty brought; Achieve and regulate and object easy to assembly.
Stay bearing plate 660 offers a vertical strip shape position-limited trough 650, one end of stop screw 651 through this groove the spacing other end be connected and fixed in the tapped bore at slide plate 600 back, and then control slide plate 600 at the sliding scale of vertical direction, make the rectilinear path of slide plate 600 can not be greater than the length of the straight line position-limited trough 650 on stay bearing plate 660.In the process that slide plate 600 moves up and down, move in the position-limited trough 650 that the stop screw 651 on it can only be offered on stay bearing plate 660.
The bottom of slide plate 600 is provided with a location hook 601, and this location hook 601, except being used for except the moiety by weight of appropriate supporting and location dish 500, can also be used to the driver train (such as can connect and drive cylinder) that connection control slide plate about 600 is shifted.And then through the driving of driver train, slide plate 600 drives dowel disc and location heating plate 100 thereon and running roller 510 to be vertically shifted up and down.Furthermore achieved that based on the longitudinal sealing temperature booster of heating plate 100 after powering; mode of operation (starting to add heat sealing) to be entered after a segment distance mobile on forming direction when entering the process of work; now the temperature booster of longitudinal sealing just reaches control position; due to inertia that paper web 200 is downward when its objective is to prevent last time from shutting down; shutting down in the process be connected with start and may occur at joining place the defect that involution is bad; move banding by limit to close, the non-involution section moved down by paper web inertia mends envelope.
During bottle placer longitudinal sealing involution, be arranged on a pinch device (meaning not shown in the figures on bottle placer on intrusion pipe, approximate location is arranged in the position near packaging material limit 210 and 220 inside Fig. 2 paper web 200) coordinate the overlay region of the tubular packaging material now through the overlay region with about 8mm herein compression, and by heater plate to complete longitudinal sealing.Wherein, on heating plate 100, the main width playing the plate face 120 of heat effect will be not less than the width (being 8mm in previous embodiment) of the overlapping region of intending involution, can be such as 12 to 16mm, when width is 16mm, the effect of involution is better, it is preferred that the width being the plate face 120 of narrower side with the plate face 110 of wider side is roughly 3 times, and now the width in plate face 110 is roughly 48mm.
Time longitudinal sealing temperature booster is out-of-run, to drive and the longitudinal sealing temperature booster that controls will enter off working state after shaping negative side moves up a segment distance through slide plate 600, now longitudinal sealing temperature booster is just separated with the pinch device on upper intrusion pipe.Start shooting after a shutdown under this particular job state based on the guide piece of slide plate 600 and roller 630 again and played important effect, having guiding and spacing function, is the tie between longitudinal sealing temperature booster control position and off-position.Longitudinal sealing temperature booster should be in stable condition after entering control position, do not rock, and rocks the involution effect that can affect longitudinal sealing.Because longitudinal sealing temperature booster is packed on the slide unit of guide piece, and said structure makes the slide unit of this guide piece have higher stability in its moving process, can not shake by slide unit because of the vibrations of machine operation, not have resonance.
In addition, when pivot shaft 610 and 620 matches with hole coaxial with the rotation axis of roller 630 on roller 630 with the shaft part (the axle rank 622 namely in Fig. 8) being circle by the cross section be arranged on pivot shaft 610 and 620 between roller 630, to keep a small amount of gap (such as between its shaft part and hole, be less than 1mm, preferred below 0.1mm), its objective is and make roller 630 can flexible rotating.Meanwhile, axle can be realized by antifriction-bearing box or plain bearing with coordinating of hole.
The shape of annular groove on roller axis cross section of roller 630 can be trapezoidal, semicircle, triangle, square or the shape such as oval.Accordingly, slide plate 600 has the marginal texture with its form fit.
In addition, shaping running roller 510 can arrange many groups along paper web forming path as required, this composing type mentioned in accompanying drawing and guiding running roller 510 are just in time the first composing type running rollers after paper web longitudinal sealing completes, relative to longitudinal sealing involution have great importance, be conducive to the paper web form keeping firm involution.
The structure of above-mentioned slide guide device, just can complete clearance control by rotating two eccentric pivot shafts 620, structure is relatively simple, and manufacture and safeguard all extremely convenient.If employing framed structure, then the FRAME COMPONENTS distortion that is difficult, that produce of roller mounting slot locating and machining comparatively large, install after gap will control by shimming, the spacing horizontal block being laterally arranged on frame front with surface groove that will lean on come with the bevelled embedded block of band be arranged on sliding panel, therefore framed structure has the problems such as complex structure, fiduciary level is low, sliding panel can rock.
Contain the bottle placer longitudinal sealing structure of above-mentioned guide piece, solve aseptic filler between start and shutting down, the excellent sealing of longitudinal sealing and the linking at sealing position, avoid the defects such as the primer solution leakage caused due to longitudinal sealing poor effect.
