(2) it is wide to be bonded scope, glues material (such as polyolefin, paraffin paper, carbon paper) to many materials, or even to generally acknowledged difficulty
It can also be bonded, especially with the connector of hot melt adhesive bonding, the bending of more than 105~106 times can be subjected to without cracking.
(3) can heat repeatedly, repeatedly bonding.
(4) performance is stablized, easy to store transport.
(5) it is of low cost.
Hot melt adhesive does not have solvent consumption, and avoiding makes the disadvantages such as adherend deformation dislocation and contraction because of the presence of solvent,
Helping, which reduces cost, improves product quality, and hot melt adhesive its physical state in certain temperature range changes and changes with temperature,
And chemical characteristic is constant, its is nonpoisonous and tasteless, belongs to environmental-protecting chemical product.
In the production of existing technology hot melt adhesive, usually screw extruder is driven to be responsible for extruding in colloid by decelerating motor in equipment
To underwater cutpellet room, it is continuous work after startup, constantly colloid is output in pelletizing room.But in practical operation, work as rear end
When bad granulating and forming or viscous knife occur for process, screw extruder still may proceed to work, so as to can cause granulation chamber and pipeline
Block, it is difficult to clear up, can seriously cause decelerating motor and screw extruder to damage.
The content of the invention
To solve the above problems, the utility model provides a kind of screw extruder overload protection for hot melt adhesive production line
Device, the situation for having prevented to block pipeline occur, protect decelerating motor and screw extruder significantly, ensure that the complete of product
Whole degree.
To achieve the above object, the technical solution adopted in the utility model is：A kind of screw rod for hot melt adhesive production line
Extruder overload protection arrangement, including screw extruder, decelerating motor, pelleter, water tank, underwater cutpellet room；It is wherein described to subtract
Frequency converter is equipped with speed motor, the output shaft of the decelerating motor and one end of screw extruder connect, the screw extruder
The other end connected with underwater cutpellet room, the side of the screw extruder is equipped with feed inlet；Wherein described underwater cutpellet room
Lower end is connected with immersible pump, and the immersible pump is arranged in water tank, wherein the upper end of the underwater cutpellet room is equipped with coil pipe, its
Described in one end of pelleter be arranged in underwater cutpellet room and be adjacent to the end of screw extruder.
Specifically, the screw extruder and the junction of underwater cutpellet room are equipped with hydraulic screen replacing device.
Specifically, the pelleter includes servomotor, cutterhead, wherein the output shaft of the servomotor is connected with cutterhead
And driving cutterhead to rotate, the cutterhead is arranged in underwater cutpellet room and is adjacent to the end of screw extruder.
The beneficial effects of the utility model are：Overload protection is carried out by having installed frequency converter additional on decelerating motor, when
Pelletizing office work is abnormal, and when viscous knife will result in blockage, decelerating motor can carry out stoppage protection automatically because stress is excessive, from
And the situation for having prevented to block pipeline occurs；The method protects decelerating motor and screw extruder relative to tradition significantly,
It ensure that the integrity degree of product, pair there has also been more preferable improvement with follow-up technique.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Drawing reference numeral explanation：1- decelerating motors；2- feed inlets；3- screw extruders；4- hydraulic screen replacing devices；5- underwater cutpellets
Room；6- immersible pumps；7- water tanks；8- servomotors；9-coil pipe；10- cutterheads.
Embodiment
Refering to Figure 1, in this embodiment, a kind of screw extruder for hot melt adhesive production line, which overloads, to be protected
Protection unit, including screw extruder 3, decelerating motor 1, pelleter, water tank 7, underwater cutpellet room 5；In wherein described decelerating motor 1
Equipped with frequency converter, the output shaft of the decelerating motor 1 is connected with one end of screw extruder 3 and drives screw extruder 3 to operate,
The other end of the screw extruder 3 is connected with underwater cutpellet room 5, and the side of the screw extruder 3 is equipped with feed inlet 2；Its
Described in the lower end of underwater cutpellet room 5 be connected with immersible pump 6, and the immersible pump 6 is arranged in water tank 7, wherein described underwater
The upper end of pelletizing room 5 is equipped with coil pipe 9, wherein one end of the pelleter be arranged in underwater cutpellet room 5 and with screw extruder 3
End be adjacent to.
Wherein by the way that raw material colloid is entered screw extruder 3 by feed inlet 2, by the deceleration electricity for being built-in with frequency converter
Machine 1 drives screw extruder 3 that colloid is expressed into underwater cutpellet room 5, and by pelleter pelletizing.Wherein underwater cutpellet room 5
Lower end is equipped with immersible pump 6, is up transported the cooling water in water tank 7 by immersible pump 6, wherein molding in underwater cutpellet room 5
