[0027] Reference Figure 1-Figure 2 and Figure 5The utility model provides an embodiment: a plastic extruder for cable processing, comprising a body 1, a belt sleeved on the front side of the body 1, a funnel 2 fixedly connected to the top of the body 1, a mounting block 9 fixedly connected to the right end of the body 1, a suction fan 17 fixedly connected to the upper side of the interior of the mounting block 9, a filter screen 10 slidably connected to the interior of the front end of the mounting block 9, a suction head 18 fixedly connected to the bottom end of the mounting block 9, a pulling component installed inside the mounting block 9, and a snap-fit ​​component installed outside the pulling component.

[0028] Specifically, the machine body 1 is the main body of the extruder, which is composed of a motor, a frame, an extrusion barrel, an auger, a feed pipe, a discharge pipe and other structures. The feed pipe is installed at the bottom end of the funnel 2, and the discharge port is set at the lower side of the mounting block 9. When the motor is started, the auger can be driven to process the raw materials inside the extrusion barrel, so that the raw materials can be formed into plastic products, and the manufactured plastic products are discharged through the discharge pipe. The machine body 1 plays a fixing role on the mounting block 9 at the right end, so that the mounting block 9 can be stably installed, and the mounting block 9 has a certain effect on the internal The suction fan 17 plays a fixing role, so that the suction fan 17 will not shake during operation. The mounting block 9 plays a limiting role on the internal filter 10, so that the filter 10 can be installed stably. The mounting block 9 plays a fixing role on the suction head 18 at the bottom, so that the suction head 18 can stably guide the odorous gas. By starting the suction fan 17, the air discharged from the discharge pipe can be guided to the filter 10 through the suction head 18, and then can be filtered by the filter 10, so that the discharged gas is relatively neat.

[0029] Reference Figure 3-Figure 4 The funnel 2 is internally rotatably connected to two connecting shafts 3, and the outside of the connecting shaft 3 is fixedly connected to two cams 4. The left end of the connecting shaft 3 is fixedly connected to a pulley 5, and the outside of the pulley 5 is provided with a belt. Two placement grooves 6 are provided on the front and back sides of the funnel 2. The outside of the cam 4 is rotatably connected to the inside of the placement groove 6. The inside of the funnel 2 is slidably connected to a screen 7, and the front and back sides of the screen 7 are fixedly connected to two connecting blocks 8. The outside of the cam 4 fits with the bottom end of the connecting block 8, and the outside of the connecting block 8 is slidably connected to the inside of the placement groove 6.

[0030] Specifically, the funnel 2 limits the internal connecting shaft 3, so that the connecting shaft 3 can rotate smoothly, and the placement groove 6 limits the internal cam 4, so that the cam 4 can rotate smoothly, so that the connecting shaft 3 can smoothly drive the cam 4 to rotate, so that the connecting block 8 can slide up and down inside the placement groove 6 without deviation, so that the placement groove 6 can stably drive the screen 7 to slide up and down, so that the screen 7 can smoothly screen the raw materials, so that the raw materials will not gather into clumps, and the raw materials can be evenly processed inside the body 1, so that the quality of the processed plastic products is higher.

[0031] Reference Figure 5-Figure 6 The pulling assembly includes two mounting grooves 12, and the two mounting grooves 12 are respectively opened on the left and right sides of the interior of the mounting block 9. A pull rod 13 is slidably connected inside the mounting groove 12, and a spring 14 is sleeved on the outside of the pull rod 13. One end of the spring 14 is fixedly connected to the lower side of the inner wall of the mounting groove 12, and the top end of the pull rod 13 is fixedly connected to a limiting block 15, and the other end of the spring 14 is fixedly connected to the bottom end of the limiting block 15, and the outside of the limiting block 15 is slidably connected to the inside of the spring 14.

[0032] Specifically, the two mounting grooves 12 are symmetrically distributed, so that the force on the locking assembly is uniform, so that the locking assembly can stably lock the filter 10, and the mounting grooves 12 limit the internal pull rod 13 and the limit block 15, so that they can slide smoothly, and the pull rod 13 limits the external spring 14, so that the spring 14 will not be offset when it is squeezed or reset. By pulling the pull rod 13 downward, the pull rod 13 can drive the limit block 15 to stably squeeze the spring 14, and then when the spring 14 resets, it can push the limit block 15 to move smoothly upward.

[0033] Reference Figure 5-Figure 6 The clamping assembly includes two clamping slots 11 and two clamping blocks 16. The clamping slot 11 is opened on the upper side of the installation slot 12. The clamping block 16 is fixedly connected to the top of the limit block 15. The outside of the clamping block 16 is slidably connected to the inside of the installation slot 12. The outer upper side of the clamping block 16 penetrates the filter 10 and is clamped with the inside of the clamping slot 11.

[0034] Specifically, the mounting groove 12 limits the internal block 16, so that the limit block 15 can stably drive the block 16 to move, and then the block 16 can stably penetrate the filter 10 and engage with the inside of the slot 11, so that the filter 10 can be stably installed inside the mounting block 9. Conversely, the filter 10 can be conveniently disassembled, so that the replacement efficiency of the filter 10 is high, which can greatly reduce the impact of the odor generated by processing on the workers' health, thereby reducing the labor cost.

[0035] Working principle: when the machine body 1 is running, its rotating shaft can drive the pulley 5 on the rear side to rotate through the belt, so that the pulley 5 on the rear side can drive the pulley 5 on the front side to rotate through the belt, so that the pulley 5 can drive the connecting shaft 3 to rotate, so that the connecting shaft 3 can push the connecting block 8 to move up and down, so that the connecting block 8 can drive the screen 7 to move up and down, so that the screen 7 can vibrate and screen the raw materials, so that the raw materials will not stick to the inside of the machine body 1, so that the quality of the processed plastic products is higher. When the filter 10 needs to be replaced, the pull rod 13 is pulled downward, so that the pull rod 13 can drive the limit block 15 to move downward, so that the limit block 15 can The spring 14 is squeezed so that the spring 14 can drive the block 16 to move downward, and then the block 16 can be separated from the slot 11 and the inside of the filter 10. At this time, the filter 10 can be easily disassembled by pulling it forward, and then the new filter 10 is slid into the inside of the mounting block 9, thereby releasing the pull rod 13, so that the spring 14 can perform a reset movement, so that the spring 14 can push the limit block 15 to move upward, and then the limit block 15 can push the block 16 to move upward, so that the block 16 can penetrate the filter 10 and engage with the inside of the slot 11, so that the replacement efficiency of the filter 10 is high, which can greatly reduce the impact of the odor generated by the processing on the workers' bodies, thereby reducing the labor cost.
