For example, an injection molding machine feeding mechanism and an injection molding machine with Chinese patent application number CN202320443988.0 include an injection molding machine body, a feed hopper is fixedly installed on the outside of the feed port of the injection molding machine body by bolts, a support frame is fixedly installed on the outside of the upper end of the feed hopper, an outer sleeve is fixedly installed on the lower end of the support frame, and a motor is fixedly installed on the upper end of the support frame. The feeding mechanism of the injection molding machine and the injection molding machine are provided with an outer sleeve at the opening at the upper end of the feed hopper through a support frame, a stirring shaft is provided on the inner side of the outer sleeve, and is driven by a motor 1, so that the stirring rod on the outer side stirs the raw materials to prevent the raw materials from solidifying. A movable frame is provided on the outer side of the outer sleeve, and a motor 2 at the upper end of the movable frame drives the gear to rotate, and the gear drives the movable frame to rotate along the outer side of the gear ring, and the movable frame drives the scraper to move on the inner wall of the feed hopper to clean the inner wall of the feed hopper to prevent the raw materials from sticking, and no manual cleaning is required, thereby improving production efficiency.

[0003] However, the above solution still has certain defects: first, the movable frame and the scraper are an integral structure, which makes it inconvenient to replace the scraper.

Secondly, it is inconvenient to seal the feed hopper, which will cause odor to be emitted from the feed hopper when the injection molding machine is working, which will affect the health of the workers and thus reduce the practicality.
