Abstract
The utility model relates to a production device of hot melt adhesive for bonding, and in particular relates to a bar-shaped high-melting-point hot melting adhesive production system which comprises a production line and an air bubble removing device, wherein the production line consists of an extruder, a cooling water tank, a traction device and a cutting device; the air bubble removing device is sleeved on a hot melt adhesive sizing die head and a clearance is reserved between the air bubble removing device and the hot melt adhesive sizing die head; and the tail end of the air bubble removing device is leveled with the tail end of the hot melt adhesive sizing die head. The air bubble removing device is additionally arranged in the bar-shaped high-melting-point hot melting adhesive production system provided by the utility model; air bubbles generated on the surface of hot melt adhesive are taken away by the air bubble removing device through driving gases in the clearance between the hot melt adhesive sizing die head and the air bubble removing device as well as in a cavity to flow rapidly by a pump, the air bubbles are prevented from remaining in the hot melt adhesive, and the quality and beautify appearance of a hot melt adhesive bar are ensured effectively.
Description
Technical field
The utility model relates to a kind of the bonding with the production equipment of PUR, is specifically related to a kind of bar-shaped high-melting-point PUR production system.
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; It does not use any solvent when producing and use; Nontoxic, tasteless, free from environmental pollution, be described as " green adhesive "; Suit especially on the production line of serialization, to use, belong to the environmental-protecting chemical product.The kind of PUR and of many uses, it mainly contains: 1) hot-fusible pressure-sensitive adhesive is used for sanltary towel, child's diaper, the disgrace of sick bed pad, old incontinence article etc.; 2) edge sealing of furniture is used PUR; 3) packing and adhesive bookbinding are used PUR; 4) fabric is used PUR, is mainly used in the production like shape, footwear, cap; 5) electronic product dress is with PUR etc.It is instant packed to be processed into different shape in the process of PUR, fuses PUR through heating power in the time of use, and the glue behind the melten gel becomes a kind of liquid, through the hot melt pipe and the thermosol gelgun of hot melt adhesive machine, delivers to the adherend surface and accomplishes bonding.
The PUR of producing on the market is Powdered or granular product mostly, and the PUR product of these shapes needs special outfit equipment in use, can't use under the condition of these special equipments not having, and causes applying of product to be obstructed.Based on this situation, practical for ease, begin to occur PUR is processed into the PUR of shapes such as strip, bar-shaped or bulk.Because the factor of equipment, producing at present remainingly in the bar-shaped PUR has great amount of bubbles, a surface topography and second-rate behind the glue rod molding.
The utility model content
In order to overcome the deficiency of prior art, the purpose of the utility model is to provide bar-shaped high-melting-point PUR production system, to solve the problem of entrapped air pockets in the hot melt rubber stick.
For addressing the above problem, the technical scheme that the utility model adopted is following:
A kind of bar-shaped high-melting-point PUR production system, it comprises the production line of being made up of extruder, bosh, draw-gear, cutter sweep; Said extruder front end is provided with feeding port; The end of extruder is provided with PUR sizing die head; Bosh is arranged on after the PUR sizing die head, and it was provided with directive wheel after draw-gear was arranged on bosh, and cutter sweep is positioned at after the draw-gear; It comprises that also one removes air bubble apparatus, said remove that air bubble apparatus is sleeved on the PUR sizing die head and and PUR sizing die head between leave the space, the end that removes air bubble apparatus flushes with the end of PUR sizing die head.
In the preferred scheme, said space is 0.5-2cm along the axial cross-sectional width of PUR sizing die head.
In the utility model, the described air bubble apparatus set inside of removing has cavity, and the below of cavity is provided with outlet, and outlet is externally connected to air-extractor.
In the preferred scheme of the utility model, said pumping equipment is water pump or oil pump.
Compare prior art; The beneficial effect of the utility model is: in the described bar-shaped high-melting-point PUR production system of the utility model; Increased by one and removed air bubble apparatus, should remove air bubble apparatus and drive PUR sizing die head and remove that the gas in the gap and cavity flows fast between the air bubble apparatus, thereby take away bubble in the generation of PUR surface through pump; Prevent residual bubble in PUR, effectively guaranteed the quality and the good looking appearance of hot melt rubber stick.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain.
Description of drawings
Fig. 1 is the described bar-shaped high-melting-point PUR production system structural representation of the utility model.
The specific embodiment
As shown in Figure 1, the described bar-shaped high-melting-point PUR production system of the utility model, it comprises the production line of being made up of extruder 1, bosh 2, draw-gear 3, cutter sweep (figure does not show); Said extruder 1 front end is provided with feeding port 11; The end of extruder 1 is provided with PUR sizing die head 12; Bosh 2 is arranged on after the PUR sizing die head 12; Draw-gear 3 is arranged on after the bosh 2, and it is provided with directive wheel 31, and cutter sweep (figure does not show) is positioned at after the draw-gear 3; It comprises that also one removes air bubble apparatus 4, said remove that air bubble apparatus 4 is sleeved on the PUR sizing die head 12 and and PUR sizing die head between leave the space, the end that removes air bubble apparatus 4 flushes with the end of PUR sizing die head 12; Described air bubble apparatus 4 set inside of removing have cavity 41, and the below of cavity is provided with outlet 42, and outlet 42 is externally connected to air-extractor 43.In the actual extrusion; The PUR raw material mixes the back according to formula rate and enters into extruder from feeding port; Fusion and extruding through PUR sizing die head in extruder is at PUR during through PUR sizing die head, under the effect of air-extractor; Quicken the speed of the gas flow on PUR surface, thereby stoped bubble to stop on the PUR surface.
In the preferred scheme, said space is 0.5-2cm along the axial cross-sectional width of PUR sizing die head.
In the preferred scheme of the utility model, said pumping equipment is water pump or oil pump.
Above-mentioned embodiment is merely the preferred implementation of the utility model; Can not limit the scope of the utility model protection 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 utility model scope required for protection.
