Abstract
The utility model relates to a heat exchange device for hot-melt adhesive production. The heat exchange device comprises an outer tube and at least one inner tube arranged inside the outer tube, wherein central axes of the outer tube and the inner tube are parallel to each other, coolant liquid is filled between the inner tube and the outer tube, and the inner tube is served as a hot-melt adhesive raw material passage. By means of accurately controlling processing parameters during hot-melt adhesive forming production and controlling the processing parameters such as temperature and viscosity through heat exchangers, paste adhesive at an outlet end is squeezed out via a mold within a proper viscosity range and temperature range, the adhesive strips can be cooled uniformly and quickly, so that the quality of cylindrical hot-melt adhesive is increased greatly, and full automatic streamline production of the cylindrical hot-melt adhesive in high quality and in scale can be realized.
Description
Technical field
The utility model relates to PUR production equipment field, the heat-exchange device that especially a kind of PUR is produced.
Background technology
PUR is a kind of widely used chemical industry bonding product, be attached to the desire bonding part with the hot melt state during use, then connection effect is played in cooling and curing back, and range of application comprises ornaments, toy, artifacts, fender, packing, woodenware assembling or electronics industry etc.PUR has strip, bar-shaped, cylindric, granular and sheet etc., and 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 size of PUR need cooperate the thermosol gelgun specification.If cylinder PUR size instability is excessive or too small, then can't cooperate the thermosol gelgun specification to produce use; Perhaps in continuous flow procedure, take place for glue amount instability, influence automated production or cause the quality problems of bonded product.Therefore the size Control of cylindric PUR is a ring important in the PUR production technology.
Common cylindric PUR adopts extrusion molding, the PUR raw material of molten condition is extruded into bosh by die head, meet water cooling and promptly solidify to form the cylinder PUR, but directly extruding and hot melting glue temperature contrast is bigger owing to stir the back in fusion, and the PUR cooling procedure is wayward, therefore cause the cylinder PUR dimensional discrepancy of production big, especially the cross section out of roundness is difficult to control, can't realize the large-scale production of high-quality, automation.
The utility model content
Shortcomings such as product size instability during the applicant produces at above-mentioned existing cylinder PUR, distortion are big, of poor quality, the heat-exchange device that provides a kind of PUR to produce, thereby improve the cylinder PUR size stability of final shaping, improve the quality and production efficiency.
The technical scheme that the utility model adopted is as follows:
The heat-exchange device that a kind of PUR is produced, described heat-exchange device comprises outer tube and pipe in inner at least one of being provided with of outer tube, the central shaft of described outer tube and interior pipe is parallel to each other, and fills cooling fluid between the inner and outer pipes, and described interior pipe is PUR raw material path.It is further characterized in that:
Pipe inside is provided with helical blade in described.
The utility model is by accurately controlling technological parameter in the PUR shaping production process; by adopting heat exchanger temperature, viscosity of technology parameter are controlled; port of export paste sizing material is extruded by mould in suitable range of viscosities and temperature range; adhesive tape can obtain rapidly cooling uniformly; thereby improved the quality of cylinder PUR greatly, can realize the high-quality of cylinder PUR, the full-automatic assembly line production of scale.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the cutaway view in A-A cross section among Fig. 1;
Fig. 3 is the schematic diagram of interior pipe among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
The utility model increases heat-exchange device the PUR raw material is stirred and cool off once more between discharge pump and extrusion die, and then enters mould and extrude.Heat-exchange device comprises heat exchanger and cooling fluid outer loop device, the PUR raw material 1 that the upstream discharge pump is extruded enters heat exchanger, raw material 1 stirred once more and abundant cooling to form paste, according to knowhow, the PUR raw material of paste can be realized stable formation.The range of viscosities of heat exchanger outlet place paste is 100,000mPas～500, and 000mPas, preferred viscosity ranges is 200,000mPas～350,000mPas, the paste raw materials temperature is controlled between 80 ℃～100 ℃.
As shown in Figure 1 and Figure 2, heat exchanger of the present utility model comprise outer tube 4 with many in manage 8, the central shaft of above-mentioned inner and outer pipes is parallel to each other, between outer tube 4 and interior pipe 8, fill cooling fluid 7, cooling fluid 7 enters from cooling fluid inlet 5, and discharge from cooling liquid outlet 3, its flow direction enters with import 2 from interior pipe 8 and the flow direction contrary of the PUR raw materials 1 that flowed out by outlet 6, has better cooling effect.As shown in Figure 3, be provided with helical blade 9, adopt stainless steel strip sheet material helically coiling to make, PUR raw material 1 helical feed of pipe 8 in can forcing to enter in the inside of interior pipe 8.
The utility model adopts heat-exchange device that the PUR raw material is stirred once more and cools off, and makes gum base ingredients more even; Heat exchanger of the present utility model inside is provided with many thin interior pipes 8, can make the raw material in the interior pipe of each root all obtain sufficient heat exchange, thereby temperature unanimity at the port of export, avoided adopting the single heat exchange inequality that causes than pipe in thick, the inside center temperature is much higher than the situation of peripheral temperature; Interior simultaneously pipe 8 inside are provided with helical blade 9 makes the PUR raw material of paste to stir more fully and to mix, and plastic emitting is more even.Suitable range of viscosities and the temperature range of paste sizing material control by to the port of export can be cooled off sizing material rapidly uniformly, thereby improved the forming quality of cylinder PUR greatly when follow-up mould is extruded; Avoided the high temperature raw material after fusion is stirred in the prior art directly to clamp-on tank, outer surface solidifies the cooling crust rapidly, thereby inner air has little time to discharge and produces a large amount of pores, simultaneously inner raw material in follow-up cooling procedure because of can not get the additional of follow-up raw material, also produce a large amount of shrinkage cavities, these are because the product quality problem that uneven quick cooling causes.
More than describing is to explanation of the present utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of the utility model spirit, the utility model can be done any type of modification.
