Abstract
The utility model discloses a production system for improving the surface smoothness of a hot melt adhesive, which consists of a front melt mixing device, a constant pressure device and constant flow pump, a heat exchange device, a shaping mould, a cooling device and a post-treatment device which are connected in series, wherein the cooling device is a vibration air dryer. Compared with the prior art, the production system for improving the surface smoothness of the hot melt adhesive adopts the vibration air dryer for cooling, so that after shaped hot melt adhesive tapes are cooled by the vibration air dryer, no air bubbles or droplets exist on the surface; consequently, the surfaces of the hot melt adhesive tapes are not caused to be rough; since the surfaces of the hot melt adhesive tapes are smooth, the hot melt adhesive tapes can closely cooperate with a hot melt adhesive gun; and therefore, the adhesion work can be carried out normally and smoothly.
Description
Technical field
The utility model relates to the PUR production field, is specifically related to a kind of production system that improves the PUR surface flatness.
Background technology
PUR is a kind of plastic adhesive, and its physical state changes with temperature change in certain temperature range, and chemical characteristic is constant, and is nonpoisonous and tasteless, belongs to the environmental-protecting chemical product.Solid-state PUR is because of carrying and convenient storage is widely used.Fixing PUR has strip, bar-shaped, cylindric, granular and sheet etc.Cylindric PUR utilizes thermosol gelgun to carry out the heat fused operation usually, and thermosol gelgun is easy to operate, safe in utilization, and the adhesive tape shape of PUR need cooperate the specification of thermosol gelgun.Usually, columned PUR adopts extrusion molding, and the hot melt rubber stick after from mould, extruding is just handled through water-cooled.Because hot melt rubber stick is in the process of quick water-cooled; Surface and inside have great amount of bubbles to be difficult to timely discharge; Cause cooled hot melt adhesive tape surface bubble depression or formation project grain to occur; Make that not only presentation quality is poor, and the project grain that the surface forms can block thermosol gelgun in thermosol gelgun, causing can't normal operation.
In sum, existing PUR production system can't realize high-quality PUR production.
The utility model content
The purpose of the utility model is to provide a kind of production system that improves the PUR surface flatness, and this production system can be produced high-quality solid state heat melten gel.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of production system that improves the PUR surface flatness, it is composed in series by preceding road consolute device, constant-voltage equipment and constant displacement pump, heat-exchange device, shaping dies, cooling device and after-treatment device, and said cooling device is the vibrations air-dry machine.
Preferably, said after-treatment device comprises surface coating device, hauling machine and guillotine.
Compared with prior art, the beneficial effect of the utility model is:
Adopt the vibrations air-dry machine to carry out cooling processing; After the cooling processing of the hot melt adhesive tape that is shaped through the vibrations air-dry machine; The surface does not have the bubble and the globule, and it is uneven to cause can not for the surface of hot melt adhesive tape, makes hot melt adhesive tape smooth surface; Can with the thermosol gelgun close fit, bonding operation can be normally, carry out smoothly.
Description of drawings
Fig. 1 is a kind of structural representation that improves the production system of PUR surface flatness of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and practical implementation example the production system of the raising PUR surface flatness of the utility model is done further explain.
As shown in Figure 1; A kind of production system that improves the PUR surface flatness of the utility model; It is composed in series by preceding road consolute device 1, constant-voltage equipment and constant displacement pump 2, heat-exchange device 3, shaping dies 4, cooling device and after-treatment device, and said cooling device is vibrations air-dry machine 5.Further, after-treatment device comprises surface coating device 6, hauling machine 7 and guillotine 8.
The operation principle of the utility model is following:
The PUR raw material mixes melting in preceding road consolute device 1; Quantitatively extrude through constant-voltage equipment and constant displacement pump 2 then; The PUR raw material of extruding stirs and cooling through heat-exchange device 3 once more, forms paste; The PUR raw material of paste just can be realized stable formation, extrudes cylindric PUR through shaping dies 4; The cylindric PUR of extruding is in the down fixing shaping of the cooling of vibrations air-dry machine 5, and its surface do not have the bubble globule, can not produce rough phenomenon, makes that the surface of product is comparatively smooth.Can also carry out surface anti sticking through surface coating device 6 to the cylindric hot melt adhesive tape that is shaped and handle, and realize sending to, be cut into the adhesive tape that suitable length is filled through guillotine 8 by the tractive force of hauling machine 7.
The foregoing description is merely the preferred implementation of the utility model; Can not limit the protection domain of the utility model with this, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement all belong to the protection domain of the utility model.
Claims (2)
