The feeding cylinder 115 is rotatably connected, and the other end of the spiral blade 118 is fixedly connected to the output end of the conveying motor 117, and the conveying motor 117 is fixedly connected to the conveying cylinder 115, and the conveying cylinder 115 is fixedly connected to the two vertical rods 116. The lower ends of the two vertical rods 116 are fixedly connected to the body 110, and the flap 121 is fixedly connected to the output end of the motor 120, and the motor 120 is fixedly connected to the feeding cylinder 119, and the feeding cylinder 119 is fixedly connected to the conveying cylinder 115. The currently provided extraction frame 108 can be freely slid and placed inside the positioning frame 106, and the operation is convenient and fast. The crushed plastic particles are directly filtered through the filter screen 109, and the larger particles can be directly extracted from the extraction frame 108 and poured back into the feeding component 105 for secondary crushing. This design is easy to produce and easy to operate, and solves the problem that larger particles need to be opened before they can be crushed, and the separation effect of larger particles and smaller particles is limited, which limits their use.
[0023] Among them, the feeding component 105 is located above the conveying component 103, the conveying component 103 is located above the crushing component 102, the crushing component 102 is located above the extruder 101, the filter screen 109 is located on the inner wall of the extraction frame 108, the extraction frame 108 is located on the inner side of the positioning frame 106, the two limiting plates 107 are both located below the positioning frame 106, and the positioning frame 106 is located on the upper top wall of the extruder 101.

The gap size of the filter screen 109 is also determined according to actual production needs. The size of the gap determines the size of the plastic particles passing through. The plastic particles that fail to pass through need to be crushed again.
[0024] Secondly, each of the foot posts 111 is located below the machine body 110, and the machine body 110 is located below the crushing assembly 102. One end of each crushing roller 114 is located on the inner wall of the crushing box 112, and the two crushing motors 113 are located on one side of the crushing box 112. The crushing box 112 is located above the machine body 110. The machine body 110 is the main body of the plastic extrusion equipment. The material is filtered through the filter screen 109 in the extraction frame 108 and discharged. The larger plastic particles are retained above the filter screen 109. After the two crushing motors 113 stop crushing, the staff holds the holding rod outside the extraction frame 108 and pulls the extraction frame 108 out of the positioning frame 106. The larger plastic particles are re-put into the feeding barrel 119 to achieve secondary crushing. The extraction frame 108 is then inserted back and the two crushing motors 113 are started to continue the crushing work.

Driven by the conveying motor 117, the spiral blade 118 drives the plastic in the conveying cylinder 115 to move and fall at the crushing box 112. The purpose of conveying the material by the spiral blade 118 is to ensure that the material will not flow into the crushing box 112 at the same time, once again avoiding the accumulation of materials, reducing the working pressure of the two crushing rollers 114, and extending the service life.
[0026] In this embodiment, due to the provision of the two limit plates 107, the extraction frame 108 can slide and be placed freely on the inner side of the positioning frame 106, and will not cause the extraction frame 108 to fall off after being inserted into the inner side of the positioning frame 106. The gap size of the filter screen 109 is also determined according to actual production needs. The size of the gap determines the size of the plastic particles passing through. The plastic particles that fail to pass through need to be crushed twice. The machine body 110 is the main body of the plastic extrusion equipment. The material is filtered through the filter screen 109 in the extraction frame 108 and discharged. The larger plastic particles are retained above the filter screen 109. After the two crushing motors 113 stop crushing, the staff holds the holding rod on the outside of the extraction frame 108 and pulls the extraction frame 108 out of the positioning frame 106, and the larger plastic particles are put back into the machine body. The feed barrel 119 is used to achieve secondary crushing, and then the extraction frame 108 is inserted back, and the two crushing motors 113 are started to continue to complete the crushing work. When the flap 121 is in a horizontal state, it just blocks the inner wall channel of the feed barrel 119, and at this time, it can prevent the outside from continuing to put in materials. Driven by the motor 120, the flap 121 rotates according to actual production needs, and then adjusts the amount of material entering the conveying barrel 115. Driven by the conveying motor 117, the spiral blade 118 drives the plastic in the conveying barrel 115 to move and fall at the crushing box 112. The purpose of conveying materials by the spiral blade 118 is to ensure that the materials will not flow into the crushing box 112 at the same time, once again avoiding the accumulation of materials, reducing the working pressure of the two crushing rollers 114, and extending the service life.
