Obviously, the described embodiments are partial embodiments of the utility model, rather than all embodiments.

[0021] In the description of the present utility model, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present utility model. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

The machine platform 1 is also equipped with a screw supply mechanism 4, which uses a vibration plate to feed materials. This is existing technology and will not be described here.

[0025] The material blocking cylinder 231 is fixedly mounted on a material blocking plate 232 on a piston rod of the material blocking cylinder 231. The material blocking cylinder 231 is fixedly mounted on the machine platform 1. The material blocking cylinder 231 drives the material blocking plate 232 to move upward, blocking the jig on the belt line 22, and preliminarily positioning the jig, making it convenient for the fixing mechanism 24 to fix the jig.

The end of the push rod 243 is conical, and a lateral clamping member 252 is hinged in the middle of the fixing member 25. The push rod 243 moves upward and is inserted into the connecting hole 26, so that the end of the push rod 243 contacts the slope 1, pushing the moving rod 28 to move. Since the middle part of the lateral clamping member 252 is hinged, under the action of the moving rod 28, one end of the lateral clamping member 252 is tilted to fix the jig.

[0028] A soft pad made of rubber material is fixedly mounted on one end of the lateral clamping member 252 to increase friction.
