Description
Technical field
The present invention relates to a kind of Reactive hot melt adhesive supplies gluing equipment.
Background technology
Reactive hot melt adhesive machine on existing market can be divided into two big class, and the first big class is to adopt press disc type, will heat
Disk be inserted in the pail pack opened, between the outer fringe seal circle of disk and the inwall of pail pack formed sealing, block wet
Glue-contact in air and pail pack, the temperature setting disk makes it heat, and the heat of disk makes to be in contact with it part
Glue melts, and is arranged on the pump above disk and pumps out the glue that these melt by required speed.The reaction of this form
Type hot melt adhesive machine suffers from the drawback that：（1）Change and need during glue to shut down：It is necessary to stop after platen is depressed into the bottom of pail pack
Glue machine even includes it and supplies the whole production line of glue, then rises platen, new one barrel of glue is opened after packaging, puts into the pressure of rise
Below disk, platen pushes, seals, and after being heated to design temperature, just can work on, which costs longer man-hour, and
Increased the defective products producing because of startup-shutdown；（2）Glue wastes more：It is easy to the logical of glue flowing due to must design on platen
Road or the fin arranging for improving melten gel speed, therefore platen is pressed to and remains therebetween when being contacted with the bottom of pail pack
Leave the glue of about 0.3-1.5 Kg, this part glue is difficult to pump out, be generally also difficult to transfer to use in next pail pack, plus
The unit price of upper Reactive hot melt adhesive is generally higher, and the value of therefore accumulative waste glue is higher；（3）Versatility is bad：To packaging
The requirement of bucket is higher, generally has two kinds of standards, and that is, the American Standard bucket for 286mm for the Europe superscript bucket and internal diameter for 280mm for the internal diameter, adapts to
The platen of Europe superscript bucket can cause edge glue leakage when using American Standard bucket, and the platen adapting to American Standard bucket is difficult to be inserted into Europe superscript
In bucket, this can select to cause during glue kind to limit to using the producer of Reactive hot melt adhesive；（4）Packing instructions to glue
High；Second big class glue machine is box glue-smelting machine, or referred to as pocket type glue-smelting machine, is directly together with its aluminum by Reactive hot melt adhesive
Foilpac bag is put in glue cylinder together, and lid seals have that partly box glue machine also can be filled with nitrogen or dry air arrives it
In, then heating glue pumps out to after design temperature；Also there is part pocket type glue-smelting machine to be provided with buffering glue melting cylinder, can solve to change glue
When the problem shut down.The shortcoming of such Reactive hot melt adhesive machine is：（1）The ability of isolation humid air is poor, causes response type
Storage in glue machine for the glue is shorter.（2）Cleaning is more difficult, and maintenance work is more, and especially glue is in glue cylinder
Inside react after solidifying；（3）The more difficult amount controlling melten gel：For this kind of glue machine not filling surge tank, can entirely during heating
Glue heating in glue cylinder, and pump glue speed out is generally relatively slow, causes whole bucket glue by long-time heating, the carbon of glue easily
The negative situation such as change, viscosity rising, molecular chain degradation；For the such glue machine equipped with surge tank, the liquid level in its surge tank passes
Sensor leads to be unable to normal table work because of reasons such as high temperature, fluctuation of pressure, glue adhesions, and then leads to melten gel mistake
Many, glue also occurs the problems such as carbonization, viscosity rising, molecular chain degradation, cleaning difficulty is occurred by long-time heating.
All also has a common shortcoming for this two classes glue machine existing, that is, the judgement for Jiao Lu blocking and report
Alert not comprehensive, it is only capable of the plastic emitting Jiao Lu after dosing pump being monitored it is impossible to be monitored to the Jiao Jiaolu that enters before dosing pump,
Therefore when entering Jiao Jiaolu and blocking occurring, equipment can not judge and report to the police, consequently, it is possible to the user to glue machine causes batch
Property waste product.
Content of the invention
