Technical Field

[0001] This utility model relates to the technical field of hot extrusion device structure, and in particular to a hot extrusion device for processing PVC conveyor belts. Background Technology

[0002] PVC conveyor belts are made of polyvinyl chloride, which consists of polyester fiber cloth and polyvinyl chloride rubber. During the production and processing of PVC conveyor belts, a hot extrusion device is used to heat the PVC material to a molten state, and then extrude it into the inside of the extrusion device to form a flat PVC conveyor belt, thereby realizing the production and processing of PVC conveyor belts.

[0003] A search revealed that authorization announcement number CN215151124U discloses a hot extrusion device for PVC processing, relating to the field of PVC processing technology. This utility model includes a worktable, a lower mold, and a pushing cylinder. The lower mold is mounted on the upper surface of the worktable and has an extrusion groove inside. A through groove is provided on the lower surface of the worktable. Several connecting rods are welded to the lower surface of the worktable, and a support plate is welded to the lower surface of the connecting rods. A pushing cylinder is mounted on the upper surface of the support plate, and a pushing rod is mounted on the upper surface of the pushing cylinder. A connecting plate is mounted on the upper surface of the pushing rod, and the connecting plate is placed inside the through groove. Several buffer springs are mounted on the upper surface of the connecting plate, and a push plate is mounted at one end of each buffer spring. This utility model, through the pushing cylinder and push plate structure, facilitates the ejection of the processed product from the mold after extrusion. The buffer springs help to buffer the thrust of the pushing cylinder when pushing the push plate, preventing excessive force during product demolding, ensuring the product's aesthetics, and improving work efficiency.

[0004] Existing hot extrusion equipment has low processing efficiency for PVC conveyor belts and cannot quickly process PVC conveyor belts. Therefore, there is an urgent need in the market for a hot extrusion equipment for PVC conveyor belt processing to solve these problems. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figure 1-4 This utility model provides an embodiment of a hot extrusion device for processing PVC conveyor belts, comprising a support frame 1, an extrusion device 2 mounted above the support frame 1, a motor 4 mounted on one side of the extrusion device 2, a spiral extrusion roller 3 mounted inside the extrusion device 2, an extrusion device box 7 mounted on one side of the support frame 1, an extrusion chamber 703 disposed inside the extrusion device box 7, a pressure groove 704 disposed at the lower end of the extrusion chamber 703, a forming seat 705 disposed at the lower end of the extrusion device box 7, a mounting frame 11 mounted on one side of the support frame 1, and rotating mounting seats 12 mounted on both sides above the mounting frame 11, with a rotating mounting seat 12 mounted on one side of each rotating mounting seat 12. The device includes an extrusion roller 13, a feed hopper 5 mounted above the extrusion device 2, a mounting base 201 at the upper end of the extrusion device 2, and a connecting base 501 at the lower end of the feed hopper 5. The connecting base 501 and the mounting base 201 are fixedly connected by fixing screws 6. By turning on the motor 4, the spiral extrusion roller 3 can convey and extrude the molten material, allowing the molten material to enter the interior of the extrusion device box 7. Then, the extrusion roller 13 can further extrude and shape the PCV conveyor belt. It should be noted that, in order to save space and highlight the innovative elements of this patent, such as the specific process of conveying the molten material, it will not be described in detail in this patent.

[0030] See Figure 1 , Figure 2 and Figure 3 One end of the extrusion device box 7 is provided with a welding seat 701, which is welded to the support frame 1. One end of the extrusion device 2 is provided with a discharge seat 202. The upper end of the extrusion device box 7 is provided with a feeding seat 702. The extrusion chamber 703 is connected to the feeding seat 702. The feeding seat 702 and the discharge seat 202 are fixedly connected by a connecting pipe 8. The forming seat 705 is an integral structure with the extrusion device box 7. The interior of the forming seat 705 is provided with a flat forming groove 706, which is connected to a pressure groove hole 704. A coolant inlet seat 9 is installed on one side of the outer wall of the extrusion device box 7, and a coolant outlet seat 10 is installed on one side of the coolant inlet seat 9. When the molten material enters the interior of the extrusion device box 7, the material is squeezed through the pressure groove hole 704 and then enters the interior of the flat forming groove 706 of the forming seat 705 for further extrusion. Then, coolant is introduced through the coolant inlet seat 9, which cools the material and allows the PVC conveyor belt to be extruded and formed.

[0031] See Figure 1 and Figure 4 The mounting frame 11 is welded to the support frame 1. Four rotating mounting seats 12 are provided, and two extrusion rollers 13 are provided. Both ends of the extrusion rollers 13 are provided with rotating shafts 14, which are rotatably connected to the rotating mounting seats 12. A motor 15 corresponding to the extrusion rollers 13 is installed on one side of one rotating mounting seat 12. The extrusion rollers 13 can be rotated and installed by the rotating mounting seats 12. The extrusion rollers 13 can further flatten the material into a conveyor belt shape, which facilitates subsequent processing.

[0032] Working principle: In use, the material is added from the feed hopper 5, and then the spiral extrusion roller 3 is rotated by turning on the motor 4. This extrudes and conveys the molten material into the extrusion device box 7, where it accumulates inside the extrusion chamber 703. It is then pressurized through the pressure groove 704 and finally enters the forming seat 705, where the flat forming groove 706 is set for flattening. At the same time, coolant is introduced through the coolant inlet 9 to cool and shape the material, thus extruding a flat object from the flat forming groove 706. The extruded object then passes between the two extrusion rollers 13. Turning on the motor 15 rotates the extrusion rollers 13, which further extrudes the material, forming the approximate shape of a conveyor belt. Finally, the object is further processed into a conveyor belt.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
