[0021] Please see Figure 1-5An embodiment of this utility model provides an extruder for an electric vehicle control cable, comprising an extrusion box 1 and a wire threading block 2. One end of the extrusion box 1 is provided with an extrusion tube, and the wire threading block 2 is provided at one end of the extrusion box 1 through the extrusion tube. A wire passage groove 18 is provided in the middle of the wire threading block 2, and the two ends of the wire passage groove 18 are respectively provided as an inlet and an outlet. An annular extrusion block 10 is provided at one end of the wire threading block 2 corresponding to the position of the extrusion tube, and an extrusion groove 11 is provided on one side of the annular extrusion block 10 and connected to the extrusion tube. Extrusion nozzles are evenly provided on the inner side of the annular extrusion block 10. A feeding box 7 is provided at the top of the other end of the extrusion box 1, and a motor 8 is provided in the middle of the other end of the extrusion box 1. The output end of the motor 8 extends into the extrusion box 1 through a bearing and a coupling and is provided with an extrusion auger 9.
[0022] When in use, PVC or Teflon material can be fed into the extrusion box 1 through the feeding box 7. Then, when heating the internal material, the motor 8 can be started to drive the extrusion auger 9 to rotate. After the material melts, it can enter the annular extrusion block 10 through the extrusion pipe and extrusion groove 11. The extrusion nozzle of the annular extrusion block 10 will extrude the molten material to cover the outside of the cable in the cable tray 18, so as to provide insulation protection.
[0023] The annular extrusion block 10 has an annular groove in the wire threading block 2 near the wire inlet, and an annular toothed block 23 is provided in the annular groove of the wire threading block 2. Both sides of the annular toothed block 23 are provided with L-shaped scrapers 22 facing the annular extrusion block 10. The bottom of the annular toothed block 23 has a gear groove 13 in the wire threading block 2. The end of the gear groove 13 corresponding to the wire inlet of the wire threading block 2 is provided with a motor 22. The output end of the motor 22 extends through a bearing to the gear groove 13, where a gear 21 is provided. The gear 21 meshes with the annular toothed block 23 through the gear groove 13 and the annular groove.
[0024] When in use, the motor 12 can be started to drive the gear 21 on its shaft to rotate, which in turn drives the annular toothed block 23 that meshes with it to rotate. The annular toothed block 23 drives the inner L-shaped scraper 22 to rotate, and the L-shaped scraper 22 between the extrusion nozzles can be rotated to scrape off the solidified PVC or Teflon material adhering to the extrusion nozzles, preventing it from adhering for a long time and affecting the extrusion effect and the cable coating effect.
[0025] A filter box 3 is located at the middle of the top of the wire block 2, and a filter plate 16 is located at the middle of the filter box 3. Activated carbon is located inside the filter plate 16. A lead screw 15 is located at the middle of the top of the filter box 3. A threaded block 19 is connected to the lead screw 15 by threads. The bottom of the threaded block 19 is connected to the top of the filter plate 16. A turntable 5 is located on the outside of the filter box 3 at the end of the lead screw 15 away from the sealing door. The turntable 5 extends into the filter box 3 and is connected to the lead screw 15 by bearings and couplings.
[0026] When in use, once the activated carbon in the filter plate 16 is saturated, the sealing door can be opened, and then the turntable 5 can be rotated to drive the lead screw 15 to rotate, causing the lead screw 15 to move the threaded block 19, which in turn moves the filter plate 16 at the bottom, allowing the filter plate 16 to be moved out through the sealing door. Then, the activated carbon in the filter plate 16 can be removed and replaced, which facilitates the replacement of the filter material and prevents it from becoming saturated and affecting the filtration effect.
[0027] Both ends of the wire inlet and outlet of the wire threading block 2 are provided with annular air suction blocks 6, and the inner side of the annular air suction blocks 6 is evenly provided with air suction holes. The middle position of the top of the annular air suction blocks 6 is provided with an air suction pipe 17, and the other end of the air suction pipe 17 extends to the bottom of the filter plate 16 inside the filter box 3. A sealing door is hinged at one end of the filter box 3 corresponding to the position of the filter plate 16. Limiting plates 20 are provided inside the filter box 3 at the top and bottom ends of the filter plate 16. A fan 4 is provided in the middle position of one side of the top of the filter box 3, and the output pipe of the fan 4 extends into the filter box 3.
[0028] When in use, the exhaust fan 4 can be started, which can draw in the gas in the filter box 3 through the output pipe. The filter box 3 can then draw in the harmful gases emitted from both ends of the wire threading block 2 through the suction pipe 17 and the annular suction block 6. The harmful gases can be drawn into the filter box 3 and adsorbed and filtered by the activated carbon in the filter plate 16. Then the gas is drawn out, which can prevent the harmful gases from being directly discharged from the inlet and outlet. Long-term absorption of these gases can affect the health of the staff.
[0029] Cooling pipes 14 are evenly surrounded inside the wire threading block 2 on the other side of the annular extrusion block 10, and both ends of the cooling pipes 14 extend downward to the outside of the wire threading block 2 and connect to the external cooling box.
[0030] When in use, cooling water can be introduced into the cooling pipe 14 so that the cooling pipe 14 can provide initial cooling to the cables in the cable tray 18.
[0031] In this embodiment, PVC or Teflon material is fed into the extrusion chamber 1 through the feeding box 7. While the material is heated, the motor 8 drives the extrusion auger 9 to rotate, causing it to melt. When extrusion of a cable is required, the cable is pulled through the cable guide groove 18. The melted material then passes through the extrusion tube and extrusion groove 11 into the annular extrusion block 10. The extrusion nozzle of the annular extrusion block 10 extrudes the molten material, covering the outside of the cable within the cable guide groove 18 for insulation protection. After being properly wrapped, the cable can continue to be transported within the cable tray 18. The cooling pipe 14 then provides initial cooling to the cable within the tray 18, followed by selective water cooling. During cable extrusion and transport, the exhaust fan 4 can be activated to draw in gas from the filter box 3 through the output pipe. The filter box 3, through the suction pipe 17 and the annular suction block 6, draws in harmful gases emitted from both ends of the cable threading block 2. These gases are then drawn into the filter box 3 and adsorbed and filtered by the activated carbon in the filter plate 16 before being exhausted. This process prevents contamination at the cable inlet and outlet. Harmful gases are directly emitted, and prolonged absorption can affect the health of workers. After the machine has cooled down for a period of time after extrusion, motor 12 can be started to drive the gear 21 on its shaft to rotate. The gear 21 drives the annular toothed block 23 that meshes with it to rotate, which in turn drives the inner L-shaped scraper 22 to rotate. The rotation of the L-shaped scraper 22 between the extrusion nozzles can scrape off the solidified PVC or Teflon material adhering to the extrusion nozzles, preventing it from adhering for a long time and affecting the extrusion effect and the cable coating effect. When excess... After the material is scraped off, a suction machine can be used to remove the scraped material from the wire groove 18 to prevent it from accumulating. When the activated carbon in the filter plate 16 is saturated, the sealing door can be opened, and then the turntable 5 can be rotated to drive the lead screw 15 to rotate, so that the lead screw 15 drives the threaded block 19 to move, and the threaded block 19 drives the filter plate 16 at the bottom to move, so that the filter plate 16 can be moved out through the sealing door. Then the activated carbon in the filter plate 16 can be taken out for replacement, which facilitates the replacement of the filter material and prevents it from affecting the filtration effect after it becomes saturated.
