[0002] After years of development, plastic extruders have evolved from single screws to twin screws, multiple screws, and even screwless models. Plastic extruders can be matched with various plastic molding auxiliary machines such as pipes, films, plastics, monofilaments, flat wires, strapping tapes, extruded nets, plates, profiles, granulation, cable coating, etc. to form various plastic extrusion molding production lines and produce various plastic products.

[0003] Publication No. CN 219543864 U discloses an injection molding machine with a replaceable feed hopper, comprising a positioning member, wherein the feed hopper and the injection pipe are separately arranged, the outer wall of the injection pipe is provided with a second feed port, the injection pipe is provided with a sliding track at the position of the feed port, the bottom of the feed hopper is connected to the sliding track, the positioning member fixes the position of the feed hopper, and the injection molding machine can be freely replaced with feed hoppers of different sizes according to the needs of the user.

[0004] However, there are some defects in the above scheme: although a detachable feed hopper is provided in the above scheme, the overall disassembly and replacement to achieve the purpose of changing to different sizes is not only time-consuming, but also leads to relatively high costs.
