[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 This utility model provides a technical solution: a TPE thermoplastic elastomer material extrusion device, comprising: an operating table 1, an extruder 2, a mounting plate 3, a guide groove 4, a cooling groove 5, a recovery bin 6, a support rod 7, a guide wheel 8, a spring 9, a drain outlet 10, a first connecting pipe 11, a spray head 12, a second connecting pipe 13, a water inlet 14, a water pump 15, a third connecting pipe 16, and a filter screen 17.

[0029] First, as attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, when the extruder 2 on the top of the operating table 1 processes and extrudes TEP thermoplastic elastic material, the processed material is extruded from the left end of the extruder 2. A mounting plate 3 is fixedly installed on the left end of the operating table 1, and a guide groove 4 is fixedly installed on the top of the mounting plate 3. The inner wall of the guide groove 4 is set in a semi-circular structure, and a support rod 7 is fixedly installed about the center point of the guide groove 4. The support rods 7 are arranged in an array about the horizontal line of the guide groove 4. A guide wheel 8 is also connected to the outside of the support rod 7, and a spring is fixedly installed inside the guide wheel 8. Spring 9, and one end of spring 9 is fixedly connected to the end of support rod 7 inside guide wheel 8, so that the extruded product enters the interior of guide groove 4 and at the same time makes the extruded product adhere to guide wheel 8. Then, due to the weight of the product itself, guide wheel 8 slides on the rod of support rod 7, and at the same time, it compresses spring 9. Thus, the movement of extruded product is guided by guide wheel 8, and the cooperation between support rod 7 and guide wheel 8 provides support. Thus, the stability of the extrusion process can be effectively maintained through the guidance and support.

[0030] As attached Figure 1 and attached Figure 2As shown, when the extruded material moves via the support rod 7 and the guide wheel 8, a detachable cooling tank 5 is fixedly installed on the top of the guide groove 4, so that the extruded finished product is placed between the guide groove 4 and the cooling tank 5. A first connecting pipe 11 is fixedly installed on the outside of the cooling tank 5, and the first connecting pipes 11 are arranged in an inverted "U" shape in an array about the horizontal line of the cooling tank 5. The first connecting pipes 11 are then fixedly connected together by a second connecting pipe 13. A water inlet 1 is fixedly installed at the left end of the second connecting pipe 13. 4. The water inlet 14 can be connected to an external water source. Since the spray heads 12 are fixedly installed in a ring array about the center point of the cooling tank 5, and the spray heads 12 are arranged in an array about the horizontal line of the cooling tank 5, the water source is injected into the interior of the first connecting pipe 11 through the water inlet 14 and the second connecting pipe 13, and then sprayed out through the spray heads 12, so as to cool the finished product between the guide tank 4 and the cooling tank 5 again. By cooling it again, the deformation and shrinkage of the finished product can be reduced, ensuring the precision and appearance quality of the product.

[0031] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 5 and attached Figure 6 As shown, when the extruded finished product is cooled, the guide groove 4 has through holes, and drain outlets 10 are arranged in an array at the bottom of the guide groove 4. This ensures that the through holes in the guide groove 4 correspond to the drain outlets 10, and that the drain outlets 10 correspond to the top of the mounting plate 3. Since the mounting plate 3 is arranged in a mesh pattern, its bottom corresponds to the recovery chamber 6 at the left end of the operating table 1. This allows the sprayed cooling water to drain through the drain outlets 10 into the surface of the mounting plate 3, and then through the mesh pattern of the mounting plate 3 into the interior of the recovery chamber 6. The upper part of the recovery chamber 6... A filter screen 17 is fixedly installed, which can filter the cooling water discharged into the recovery chamber 6. A water pump 15 is fixedly installed at the front end of the recovery chamber 6, and the input end of the water pump 15 is fixedly connected to the recovery chamber 6. A third connecting pipe 16 is fixedly installed at the output end of the water pump 15. The upper end of the third connecting pipe 16 is fixedly connected to one of the first connecting pipes 11 on the outside of the cooling tank 5. This allows the water pump 15 to achieve water recycling through the cooperation between the third connecting pipe 16 and the first connecting pipes 11, which can significantly reduce water consumption and wastewater discharge, thereby reducing overall energy consumption.
