The feed cylinder 15 is conical. The cylinder wall of the extruder is provided with an interlayer, and a plurality of groups of electric heating wires are arranged in the interlayer.
First, the operator prepares the raw materials required for manufacturing the seal and pours them into the feed cylinders 15, the lower end of each feed cylinder 15 being inserted into the corresponding feed pipe 12, ensuring that the raw materials can be smoothly fed into the extrusion cylinder 11. The operator activates the extruder and the raw materials enter the extrusion barrel 11 through the feed pipe 12, are extruded and injected uniformly into the extrusion die 14 by the extrusion and mixing action of the extrusion screw 13. The feedstock passes through the forming section of extrusion die 14 to form the desired seal shape according to the die design. The connection of the extrusion die 14 to the barrel 11 by the quick release assembly 30 ensures that the extrusion die 14 is easy to replace and maintain. The extruder can continue to operate to produce the sealing strip until the desired amount is completed or the raw material is exhausted.
In the working process, the first motor 22 drives the stirring shaft 21 to rotate, the stirring shaft 21 drives the scraping plate 23 to rotate through the connecting rod 24, the scraping plate 23 is in sliding connection with the inner wall of the feeding cylinder 15, raw materials adhered to the inner wall of the feeding cylinder 15 are scraped off under the continuous rotating action of the scraping plate 23, and the phenomenon that the raw materials are coagulated into blocks on the inner surface of the feeding cylinder 15 due to untimely cleaning is effectively avoided.

When the extrusion die 14 needs to be replaced, firstly, an operator presses a button 38 on the moving rod 31 to separate the clamping groove 34 of the square block 33 from the lower end of the inserting rod 35, and then, the operator can directly withdraw the inserting rod 35 from the second sliding groove 36 of the extrusion barrel 11, and the extrusion die 14 is completely separated from the extrusion barrel 11. After the extrusion die 14 is removed, the operator may perform cleaning, maintenance, or replacement work.
