The output end of the material pushing mechanism forms a material pushing station. The material pushing mechanism is connected to the swing mechanism. The output end of the swing mechanism forms a material pressing station. The material pressing station is located in front of the material pushing station;

[0018] The swinging mechanism includes a swinging seat 8, a base 9, and an inclined block 10. The base 9 is arranged on the fixed frame 1. The swinging seat 8 is swingably arranged on the top of the base 9. A rotating shaft 12 is arranged on the top of the base 9.
