The movable door will not open until the collection box is at the bottom of the collection dish, ensuring that the ceramic material can be completely collected, simplifying the operating process, reducing the risk of operating errors, and preventing the ceramic material from leaking without being collected, thereby keeping the working environment clean and safe. The push plate rotates and the connecting rod drives the scraper rod to start rotating. When the movable door is opened, the scraper rod rotates to scrape the ceramic material at the bottom of the collection dish, ensuring that the material can flow smoothly when the movable door is opened, reducing the risk of ceramic material accumulating at the bottom of the collection dish and causing blockage.

Through intermittent opening and resetting, the feed can be reasonably controlled to reduce the wear between the mold and the workpiece, make the processed surface smoother, improve the quality of the finished product, and prevent excessive material from entering and causing damage to the machine.

[0021] The feed limiting device also includes a slider 1 407, a slider 2 408, a rotating rod 409 and a push rod 410. The slider 1 407 is slidably installed on the inner wall of the feed port 4, the slider 2 408 is slidably installed on the inner wall of the feed port 4, the slider 1 407 and the slider 2 408 are connected by the rotating rod 409, and the push rod 410 is fixedly installed at the bottom of the slider 2 408.

At the same time, the rotation of the flap 404 will push the slider 1 407 to start sliding, and the slider 1 407 slides through the rotating rod 409 to push the slider 2 408 to start sliding. The sliding of the slider 2 408 drives the push rod 410 to start sliding, and the sliding of the push rod 410 will push the material that may be blocked in the feed port 4, thereby maintaining a smooth working state, improving overall work efficiency and improving operational safety, so that operators can carry out production more confidently and prevent material blockage from causing machine damage.
