Description

Technical Field

[0001] This utility model belongs to the field of automotive parts manufacturing technology, specifically a PVC extruder based on automotive cables. Background Technology

[0002] With the development of society, PVC extruders are often needed in other fields such as construction, packaging, automobiles, and electronics. A PVC extruder is a type of plastic processing machinery, mainly used to process polyvinyl chloride (PVC) plastic raw materials into plastic products of various shapes.

[0003] In automotive electrical systems, cables play a crucial role in transmitting electrical energy and signals. To prevent current leakage and short circuits and ensure the safe and stable operation of automotive electrical systems, cables require a good insulation layer. PVC (polyvinyl chloride) material itself has excellent electrical insulation properties. Using a PVC extruder, PVC material can be evenly wrapped around the conductor of automotive cables to form a continuous and dense insulation layer.

[0004] In the existing technology, through long-term use and observation, it has been found that existing PVC extruders generally do not pre-treat PVC materials before use. Raw materials without pre-treatment may contain moisture, which will form water vapor during the extrusion process, causing pores and defects in the PVC melt, thereby reducing the mechanical strength of the cable, such as tensile strength and impact resistance, and affecting the service life and safety of the cable. Therefore, in order to address the above problems, a PVC extruder based on automotive cables is proposed. Utility Model Content

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1 - Figure 4This utility model provides a PVC extruder based on automotive cables, including an extruder body 1. A processing box 10 is provided at the top of the extruder body 1, and a box cover 11 is provided at the top of the processing box 10. A filling port 12 is provided on the side wall of the box cover 11. Fixing rods 13 are symmetrically fixed to the side wall of the box cover 11, and servo motors 14 are fixed to the side wall of the fixing rods 13. A rotating shaft 15 is fixed to the output end of the servo motor 14. The rotating shaft 15 passes through the surface of the box cover 11 and is rotatably connected to it. Multiple sets of... The mixing rod 16 and multiple sets of heating tubes 17 are fixed to the side wall of the processing box 10. A feed inlet 18 is provided on the side wall of the processing box 10, and an electric valve 19 is rotatably installed on the side wall of the feed inlet 18. During operation, the extruder body 1 supports the processing box 10, the box cover 11 supports the fixing rod 13, and the fixing rod 13 supports the servo motor 14. The operator adds material to the filling port 12, allowing it to flow into the processing box 10. The heating tubes 17 then heat the processing box 10. The processing chamber 10 is equipped with a temperature sensor to monitor the temperature inside. When the predetermined temperature is reached, the heating element 17 will stop working. The heating temperature of the heating element 17 is the preheating and drying temperature, so it will not affect the material. When the material is drying in the processing chamber 10, the cover 11 supports the fixing rod 13, which in turn supports the servo motor 14. The servo motor 14 drives the rotating shaft 15 to rotate, which in turn drives the stirring rod 16 to stir the material, making the material dry more evenly. After drying, the electric valve 19 is opened, and the material can be added into the extruder body 1 through the feed port 18. This design is not only simple and convenient to operate, but also allows the PVC material to be pretreated before use, reducing the moisture content of the raw material and stirring the material to make the material dry more evenly, thereby improving the mechanical strength of the cable and extending its service life and safety.

[0027] Furthermore, such as Figure 1 , Figure 3 As shown, slots 2 are symmetrically fixed to the side wall of the filling port 12. An insert block 21 is slidably arranged on the inner side of the slot 2. A filter plate 22 is fixed to the side wall of the insert block 21. During operation, the insert block 21 can be removed from the slot 2 by the operator, thereby disassembling the filter plate 22. When the material is filled, the filter plate 22 can perform screening and filtration, thereby ensuring that the particle size of the material is consistent. This design allows the material to be screened and filtered when it is filled, thus ensuring that the particle size of the material is consistent. It also makes it easy for the operator to install and disassemble the filter plate 22, thereby facilitating the unified recycling of the unqualified material after screening.

[0028] Furthermore, such as Figure 1 , Figure 2 As shown, the top of the processing box 10 is symmetrically provided with positioning grooves 3. A first magnetic block 31 is fixedly connected to the inner side of the positioning groove 3, and a second magnetic block 32 is symmetrically fixed to the side wall of the box cover 11. The connection between the second magnetic block 32 and the first magnetic block 31 is magnetic connection. During operation, when the operator is installing the box cover 11, the second magnetic block 32 can be automatically inserted into the positioning groove 3 and connected to the first magnetic block 31 by bringing the first magnetic block 31 and the second magnetic block 32 close together, thereby achieving the positioning function. Through this design, the box cover 11 can be quickly positioned when it is installed, which makes it easier for the operator to install the box cover 11.

[0029] Furthermore, such as Figure 1 , Figure 2 As shown, a cover 4 is rotatably mounted on the side wall of the filling port 12. A handle 41 is fixedly connected to the side wall of the cover 4, and a sealing strip 42 is fixedly connected to the side wall of the cover 4. During operation, the sealing strip 42 can be connected through the cover 4, which can improve the sealing performance. The handle 41 makes it easy for the operator to open and close the cover 4. This design makes it easy for the operator to open and close the cover 4 and can improve the sealing performance, thereby reducing the amount of dust and impurities that may enter the filling port 12 and contaminate the material.

[0030] Furthermore, such as Figure 3 As shown, a support rod 5 is fixed to the side wall of the slot 2, and a limiting plate 51 is fixed to the side wall of the support rod 5. During operation, the support rod 5 can support the limiting plate 51, and the limiting plate 51 can play a limiting role. This design can play a limiting role, thereby making it easier for the operator to insert the plug 21 into the slot 2.

[0031] Furthermore, such as Figure 2 As shown, the side wall of the handle 41 is provided with an anti-slip sleeve 6. The anti-slip sleeve 6 is connected to the handle 41 by adhesive bonding. During operation, the anti-slip sleeve 6 can increase the friction of the hand. This design can increase the friction of the hand, so that the operator can pull the cover 4.

[0032] Furthermore, such as Figure 1 As shown, the side wall of the processing box 10 is provided with an observation window 7. The observation window 7 is made of transparent material. During operation, the staff can easily observe the inside of the processing box 10 through the observation window 7. This design facilitates the staff to observe the material processing process inside the processing box 10 and improves its practicality.

[0033] Working Principle: The extruder body 1 supports the processing chamber 10, the chamber cover 11 supports the fixing rod 13, and the fixing rod 13 supports the servo motor 14. The operator adds material into the filling port 12, allowing it to flow into the processing chamber 10. The heating element 17 heats the processing chamber 10. A temperature sensor inside the processing chamber 10 monitors the internal temperature. When the predetermined temperature is reached, the heating element 17 stops working. The heating temperature of the heating element 17 is the preheating drying temperature, thus not affecting the material. While the material is drying in the processing chamber 10, the chamber cover 11 supports the fixing rod 13, which in turn supports the servo motor 14. The servo motor 14 rotates, driving the rotating shaft 15, which in turn drives the stirring rod 16 to stir the material, resulting in more uniform drying. After drying, the material is fed into the extruder body 1 through the feed inlet 18 by opening the electric valve 19. The filter plate 22 can be disassembled by removing the insert 21 from the slot 2. The filter plate 22 can screen and filter the material when it is added, so that the particle size of the material is consistent. When the operator installs the cover 11, the second magnetic block 32 can be automatically inserted into the positioning groove 3 and connected to the first magnetic block 31 by bringing the first magnetic block 31 close to it, so as to play a positioning role. The sealing strip 42 can be connected to the cover 4, which can improve the sealing performance. The handle 41 makes it easy for the operator to open and close the cover 4. The support rod 5 can support the limiting plate 51, which can play a limiting role. The anti-slip sleeve 6 can increase the friction of the hand. The observation window 7 makes it easy for the operator to observe the inside of the processing box 10.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
