Description

A kind of small-sized melt spraying non-woven fabrics production line

Technical field

The invention belongs to technical field of textile machine, be specifically related to a kind of small-sized melt spraying non-woven fabrics production line.

Background technology

The melt spraying non-woven fabrics product is mainly used in and filters series products, hot melt adhesive, insulation material and rag or the like, the multinomial important performance of melt spraying non-woven fabrics product need be embodied by the character of superfine fibre, and the quality of superfine fibre is the difficult point place in the melt spraying non-woven fabrics processing.

Because polymer melt needs the buildup of monoblock cloth cover even when melting and spraying; processing machine of the prior art mainly is to finish production by once spraying a silk moulding; add man-hour need with the wide mould of cloth cover; cause the bulky mechanism of machine complexity; and melt and spray and be mostly one-shot forming; require high to mould; be difficult to reach high-quality; also be difficult to obtain the product of high grammes per square metre; and need continuous high temperature in the process, guaranteeing carrying out smoothly of whole process of production, in case just shut down need more mold exchange safeguard; otherwise mould can not use continuously, causes processing and maintenance cost high.

Summary of the invention

The small-sized melt spraying non-woven fabrics production line that the purpose of this invention is to provide a kind of simple in structure, low processing cost.

The technical solution adopted for the present invention to solve the technical problems is: a kind of small-sized melt spraying non-woven fabrics production line, comprise extrusion device, feeder and receiving system, described extrusion device comprises screw extruder and is located at loading hopper on the screw extruder, reductor and screw rod motor, the screw extruder front end is provided with spinning pack, described feeder comprises the heat conduction tracheae that is connected with spinning pack, be connected with steam line in turn on the heat conduction tracheae, heater and roots blower, described receiving system comprises frame and is located at uncoil-stand on the frame, the front side of uncoil-stand is respectively equipped with into lace curtaining and wind-up roll with the below, described frame bottom also is provided with drive motors, be connected with sprocket wheel on the drive motors output shaft, the frame bottom is installed on roller, roller is connected with sprocket wheel by chain, the frame downside is provided with guide rail, and two ends, the guide rail left and right sides are provided with stopping means.

Wherein, described stopping means is made up of to the buffering power assistant spring of being located at the spacing lever in the stand and being located at spacing lever afterbody stand, level.

In addition, described spinning pack comprises connector, base plate, die head and atmospheric pressure board

The invention has the beneficial effects as follows: screw extruder is extruded polymer melt from spinning pack, form the melt thread, the air of heating blows out at a high speed from air channel, spinning pack both sides, polymer molten fluid is stretched, cooling air certain position below die head mend from both sides into, make the fiber crystallisation by cooling, the superfine fibre of high velocity air stretch forming is collected in into lace curtaining uniformly, with the fiber cloth reinforced melt-blown non-woven material that becomes, the positive and negative rotation in motor gap of frame bottom, drive chassis to reciprocating motion, makes polymer melt can melt and spray on the monoblock cloth in level, and structure of the present invention is quite simple, the equipment input is lower, maintenance cost is low, low processing cost, product quality height, owing to be reciprocal lay-up molding, obtaining high grammes per square metre product easily, is a kind of simple and practical melt spraying non-woven fabrics production line, also is used in compound layer of meltblown fibers on the textiles.

Fig. 2 is the structural representation of receiving system side-looking direction of the present invention.

The specific embodiment

Below in conjunction with drawings and Examples the present invention is described in further detail.

With reference to Fig. 1, shown in Figure 2, the invention discloses a kind of small-sized melt spraying non-woven fabrics production line, comprise extrusion device, feeder and receiving system, described extrusion device comprises screw extruder 21 and is located at loading hopper 22 on the screw extruder 21, reductor 23 and screw rod motor 24, screw extruder 21 front ends are provided with spinning pack 26, described feeder comprises the heat conduction tracheae 27 that is connected with spinning pack 26, be connected with steam line 28 on the heat conduction tracheae 27 in turn, heater 29 and roots blower 30, described receiving system comprises frame 1 and is located at uncoil-stand 2 on the frame 1, the front side of uncoil-stand 2 is respectively equipped with into lace curtaining 3 and wind-up roll 4 with the below, described frame 1 bottom also is provided with drive motors 5, be connected with sprocket wheel 6 on drive motors 5 output shafts, frame 1 bottom is installed on roller 7, roller 7 is connected with sprocket wheel 6 by chain 8, frame 1 downside is provided with guide rail 9, two ends, guide rail 9 left and right sides are provided with stopping means, described stopping means is by stand 11, level is formed with the buffering power assistant spring 13 of being located at spacing lever 12 afterbodys to the spacing lever of being located in the stand 11 12, and described spinning pack 26 comprises connector, base plate, die head and atmospheric pressure board 25.

Screw extruder 21 is extruded polymer melt from spinning pack 26, form the melt thread, thermal current at a high speed blows out at a high speed from air channel, spinning pack 26 both sides, polymer molten fluid is carried out drawing-off, forming superfine fibre is sprayed on the one-tenth lace curtaining 3 of receiving system uniformly, meanwhile, the forward rotation and the backward rotation in drive motors 5 gaps of frame 1 bottom, rotate and reverse by chain 8 driving rolls 7, drive chassis 1 along guide rail 9 levels to reciprocating motion, make melt-blown material becoming back and forth lay-up molding uniformly on the lace curtaining 3, last rolling finally obtains the nonwoven fabric product on wind-up roll 4.

In addition, uncoil-stand 2 on the frame 1 can be placed the textile material of rolling, when screw extruder 21 is extruded polymer melt from spinning pack 26, textile material from top to bottom is transported on the lace curtaining 3, melt-blown material can evenly be sprayed on the textile material, can carry out the production of the compound melt-blown material of textiles by technology as mentioned above.

When frame 1 runs to guide rail 9 ends, stopping means and frame 1 collision, the inertia force by spacing lever 12 and buffering power assistant spring 13 absorption frames 1 can stop frame 1 rapidly, carries out the walking of other direction.

Structure of the present invention is quite simple, and the equipment input is lower, and maintenance cost is low, low processing cost, the product quality height is owing to be reciprocal lay-up molding, obtaining high grammes per square metre product easily, is a kind of simple and practical melt spraying non-woven fabrics production line, also is used in compound layer of meltblown fibers on the textiles.
