The buffer assembly includes a slide column 8, which is symmetrically slidably connected to the inside of the top plate 3. The outer sides of the two slide columns 8 are sleeved with a No. 2 spring 11. The bottoms of the two slide columns 8 are fixedly connected to the top of the mounting frame 5. The tops of the two slide columns 8 are fixedly connected to a limit plate 12.

[0023] In the above technical solution, considering that in the actual cutting process, the cut object may be offset due to touching, resulting in inaccurate cutting, in order to solve such a problem, the specific operations are as follows:

[0024] Reference Figure 1 - Figure 4In a preferred embodiment, the output end of the cylinder 4 drives the mounting frame 5 to move downward, and then the mounting frame 5 drives the chopping blade 6 to move downward until the two pressing rollers 703 first contact the top of the workpiece to be cut. As the output end of the cylinder 4 continues to move downward, the two connecting rods 702 drive the pressing rollers 703 to rotate around the rotating block 701. Through the provided stabilizing mechanism, under the tension of the No. 1 spring 705, the two pressing rollers 703 continue to press the workpiece downward, avoiding the displacement of the workpiece during the cutting process, thereby causing the cutting position to shift, ensuring the accuracy of the cutting and improving the qualified rate of the product. As the mounting frame 5 moves downward, the sliding column 8 drives the limit plate 12 to move downward, and the No. 2 spring 11 is compressed. Through the provided buffer assembly, under the tension of the No. 2 spring 11, the cutting of the chopping blade 6 can be buffered, avoiding the chopping blade 6 from being damaged by too much downward impact force, protecting the operation safety of the chopping blade 6 and extending its service life.

[0025] Reference Figure 1 - Figure 4 In a preferred embodiment, a rubber pad 9 for preventing slipping is fixedly connected to the bottom of the bottom plate 1. The pressing roller 703 is made of rubber material. A controller 10 is fixedly connected to the outer side of the support plate 2. The cylinder 4 is electrically connected to the controller 10.

[0026] Working principle: In actual use, the staff places the workpiece to be cut on the top of the base plate 1, and then starts the cylinder 4. The output end of the cylinder 4 drives the mounting frame 5 to move downward, and then the mounting frame 5 drives the chopping blade 6 to move downward until the two pressing rollers 703 first contact the top of the workpiece to be cut. As the output end of the cylinder 4 continues to move downward, the two connecting rods 702 drive the pressing rollers 703 to rotate around the rotating block 701. Under the pulling force of the No. 1 spring 705, the two pressing rollers 703 continue to press the workpiece downward, and then the chopping blade 6 begins to cut the workpiece. At the same time, as the mounting frame 5 moves downward, the sliding column 8 drives the limit plate 12 to move downward, and the No. 2 spring 11 is compressed. Under the tension of the No. 2 spring 11, the cutting of the chopping blade 6 can be buffered. At this point, the staff has completed the work of processing the workpiece.
