[0023] like Figures 1 to 4As shown, the utility model is an extrusion device for a modified plastic cable sheath, comprising: an extruder 1, a feed box 2, a cooling box 3 for cooling the cable sheath, a dust removal component 4 for removing dust from the raw material, and a filter component 5 for filtering the gas entering the cooling box 3. After the extruder 1 extrude the finished cable sheath, it needs to be cooled to quickly stabilize its internal structure, and before the gas is cooled, the gas needs to be filtered to prevent foreign matter in the gas from being blown to the surface of the cable sheath, causing damage to the surface of the cable sheath. The modified plastic is added into the extruder 1 through the feed box 2, and is cooled through the cooling box 3 after being processed by the extruder 1. Before the modified plastic enters the extruder 1, it is dusted by the dust removal component 4, and before the gas enters the cooling box 3, it is filtered by the filter component 5 to ensure the product quality of the cable sheath.

[0024] The dust removal component 4 includes: an exhaust end 41 for extracting the gas inside the cooling box 3, an outlet end 42 for blowing the dust on the surface of the raw material, and a power source 43 for driving the gas flow. The exhaust end 41, the outlet end 42 and the power source 43 are detachably connected. The power source 43 is a fan. The fan draws the clean gas inside the cooling box 3 into the outlet end 42 through the exhaust end 41 and sprays it out. The outlet end 42 is arranged on the feed box 2. The feed box 2 is provided with a feed port 21. The feed port 21 is trumpet-shaped. The trumpet-shaped feed port 21 can In order to accommodate more modified plastics and reduce the amount of material discharged, the air outlet end 42 is convenient for blowing the dust on the modified plastic. The modified plastic falls downward through the feed port 21. At this time, the air outlet end 42 blows clean gas to the surface of the modified plastic. On the one hand, it can make the dust on the surface of the modified plastic fall off, and on the other hand, it can blow the modified plastic to the material port of the extruder 1. Since the quality and size of the dust and the modified plastic are different, the dust is blown to one end of the feed box 2 to prevent the dust from following the modified plastic into the extruder 1, thereby completing the cleaning of the modified plastic.

[0025] The filter assembly 5 includes: a filter box 51 for filtering gas, an air inlet 52 is opened on the surface of the filter box 51, a filter screen 53, the filter screen 53 can be detachably installed inside the filter box 51, a cleaning brush 54 for cleaning the filter screen 53, a screw rod 55 for driving the cleaning brush 54 to move, a cooling pipe 59 for conveying gas to the cooling box 3, a cooling port 58, and a connecting rod 57 for driving the cooling port 58 to swing, one end of the screw rod 55 is fixedly connected to a motor 56, the cleaning brush 54 is threadedly connected to the screw rod 55, the cleaning brush 54 is threadedly connected to the connecting rod 57 is rotatably connected, the other end of the connecting rod 57 is hinged on the cooling port 58, and a rotating shaft is installed at one end of the connecting rod 57 near the cooling box 3. The connecting rod 57 is rotatably connected to the cooling box 3 through the rotating shaft. When the motor 56 drives the screw rod 55 to rotate, it drives the cleaning brush 54 to move back and forth on the surface of the filter screen 53, which can sweep away dust and impurities adhered to the surface of the filter screen 53, thereby ensuring the filtering efficiency of the filter screen 53. At the same time, when brushing the surface of the filter screen 53, the cooling port 58 is driven to swing through the connecting rod 57, so that the area where the gas is blown to the cable sheath is larger, and the cooling effect is better.

[0026] The surface of the screw rod 55 is provided with two groups of threads with opposite rotation directions, and the two groups of threads are threadedly connected with a cleaning brush 54, so that the cleaning brush 54 has a better cleaning effect on the surface of the filter screen 53.

[0027] In order to ensure the swinging effect of the cooling port 58, a hose can be selected for the cooling pipe 59, and in order to ensure that the gas stably enters the cooling box 3, a fan can be installed on the surface of the cooling pipe 59 to ensure the cooling effect of the gas on the cable sheath.

[0028] Working principle:

[0029] When the motor 56 drives the screw rod 55 to rotate, it drives the cleaning brush 54 to move back and forth on the surface of the filter 53, which can sweep away the dust and impurities adhering to the surface of the filter 53, thereby ensuring the filtering efficiency of the filter 53. At the same time, when brushing the surface of the filter 53, the cooling port 58 is driven to swing through the connecting rod 57, and at the same time, the fan draws the clean gas inside the cooling box 3 into the air outlet 42 through the exhaust end 41 and sprays it out. On the one hand, it can make the dust on the surface of the modified plastic fall off, and on the other hand, it can blow the modified plastic to the material port of the extruder 1 for unloading.
