[0039] In the specific implementation, the lifting device 33 is a cylinder for driving the lifting frame 31 and the plurality of support rods 32 to move up and down synchronously. The top of each support rod 32 is provided with a universal ball 321, which facilitates the pushing of the board placed on the support rod 32 after the support rod 32 is lifted, and facilitates the movement and adjustment of the board.

[0040] In the push plate feeding process, the lifting device 33 drives the plurality of support rods 32 on the lifting frame 31 to vertically rise upwards. At the same time, the door-shaped frame 41 in the flip mechanism 40 is driven by the guide roller set 311 to a vertical state to avoid the rising support rods 32, so that the top surface of the support rod 32 is lifted to a height higher than the top surface of the spike module 20.
