[0033] The working principle and use process of the utility model: before using the plastic extrusion mechanism, the main body 100 of the plastic extrusion mechanism can be stably placed at the processing position through the support seat 104 contacting the ground. After the main body 100 of the plastic extrusion mechanism is stably placed, the raw material is injected into the inside of the feed hopper 102, and the stirring element rotates and stirs the raw material, and the raw material is filtered through the filter screen 105 to enter the inside of the extrusion operation main body 101, and is extruded by the extrusion operation main body 101 and extruded by the extrusion head 103, so it is convenient to extrude the plastic through the main body 100 of the plastic extrusion mechanism;

When the plastic extrusion mechanism body 100 is moved, the limit block 1055 is controlled to slide in the limit groove 1054, so that the clamp head 1057 is stably moved and clamped in the clamp hole 1056, which is convenient for fixing the filter 105 in the feeding hopper 102 for filtering. Therefore, when the plastic extrusion mechanism body 100 is used for a long time and the filter 105 in the feeding hopper 102 is maintained, the filter 105 can be disassembled and maintained separately by the opposite operation, which is simple and convenient to disassemble and assemble, thereby improving the convenience of the plastic extrusion mechanism body 100 for maintaining and disassembling the filter 105 during the plastic extrusion operation;

[0035] Finally, when the plastic extrusion mechanism body 100 is in use, after the material is injected into the feed hopper 102, the slider 1025 and the slide groove 1024 slide to stably slide the guard plate 1022 inside the mounting groove 1021 and close it inside the top of the feed hopper 102, so that the two guard plates 1022 can be closed to the top of the feed hopper 102, and the fixing bolts 1023 are rotated to fix and protect the guard plates 1022.
