The plate material is conveyed and moved leftward and rightward by the plate material feeding mechanism, the plate material is punched by the cooperation of the movable die 2 and the fixed die 3, the punched plate material is also moved during the conveying process, the plate material is pressed by the rubber rollers 6, at the same time, the rubber rollers 6 are driven to rotate synchronously, the plate material waste is conveyed by the friction of the rubber rollers 6, the plate material feeding and the plate material waste are synchronously conveyed, the bending of the plate material is prevented, and at the same time, when the plate material is conveyed and moved leftward and rightward by the plate material feeding mechanism, the rubber rollers 6 are synchronously rotated by the friction of the rubber rollers 6 and the plate material, the rubber rollers 6 are moved along with the leftward and rightward movement of the plate material, the plate material waste is pressed at any time, the plate material waste is kept in the conveying state at any time, and the bending of the plate material is further prevented.

[0022] As shown in the embodiment, Figures 1 to 4 the support rollers 9 are rotatably installed between the two mounting plates 4 by bearings, and the plate material is between the support rollers 9 and the rubber rollers 6.

[0023] When the rubber rollers 6 on the rotating rollers 10 press the plate material, the plate material is controlled to be between the rubber rollers 6 and the support rollers 9, and the support rollers 9 can support the plate material.

[0024] As shown in the embodiment, Figures 1 to 4 the rotating rollers 10 are rotatably installed between the two fixed plates 5 by bearings, and the rubber rollers 6 are slidingly installed on the outer side of the rotating rollers 10.

[0025] When the plate material is conveyed and moved leftward and rightward by the plate material feeding mechanism, the rubber rollers 6 are synchronously rotated by the friction of the rubber rollers 6 and the plate material, the rubber rollers 6 are synchronously moved leftward and rightward on the outer side of the rotating rollers 10 along with the leftward and rightward movement of the plate material, and the plate material waste is pressed at any time.

[0026] As shown in the embodiment, Figures 1 to 4 one side of one of the fixed plates 5 is fixedly installed with a feeding motor 11, the output end of the feeding motor 11 is fixedly connected with one end of the rotating roller 10, limit blocks 12 are fixedly installed on the outer side of the rotating roller 10 in a symmetrical manner, limit grooves 13 are symmetrically formed in the inner ring of the rubber roller 6, and the limit blocks 12 and the limit grooves 13 are slidingly connected.

[0027] The feeding motor 11 drives the rotating roller 10 to rotate. The mutual restriction between the limiting block 12 and the limiting groove 13 drives the rubber roller 6 to rotate synchronously. The friction of the rubber roller 6 on the waste board material will realize the conveying of the waste board material.

[0028] like Figures 1 to 4 As shown, the top of the mounting plate 4 is symmetrically fixedly mounted with limit rods 14, and the fixing plate 5 is slidably mounted between the two limit rods 14.

The moving frame 7 is threadedly connected to the screw 17.

[0031] When the waste board moves left and right along with the raw board material, the moving motor 18 drives the screw 17 to rotate. The moving frame 7 is connected to the screw 17 by a thread, which causes the moving frame 7 to slide and move left and right synchronously inside the fixed frame 16. This achieves the conveying and positioning of the waste board material and further prevents the waste board material from twisting.

[0032] like Figures 1 to 4 As shown, the top of both ends of the movable frame 7 are symmetrically provided with sliding holes 19, and a sliding rod 20 is symmetrically fixedly installed on one side of the U-shaped frame 8.
