[0026] The effects achieved by the above components are as follows: first, different convex molds 309 are installed at the four ends of the cross rod 308 as needed, and the motor 1 304 is started to rotate the active bevel gear 305, and then the driven bevel gear 306 drives the rotating shaft 1 307 to rotate to switch different convex molds 309, and the cylinder 1 301 is started to move the movable platform 302 downward and then drive the convex mold 309 downward to process the paper corner protectors that need to be bent into different shapes.

[0027] Specifically, a support plate 310 is fixedly connected to the surface of the support frame 1, a rotating shaft 311 is rotatably connected to the inner wall of the support plate 310, a square mold 312 is fixedly installed on the surface of the rotating shaft 311, a motor 313 is fixedly installed on the surface of the support plate 310, and the output end of the motor 313 is fixedly connected to one end of the rotating shaft 311.

[0028] The effect achieved by the above components is: starting the second motor 313 causes the second shaft 311 to rotate, thereby causing the square mold 312 to rotate.

When performing the bending operation, start the motor 1 304 to make the active bevel gear 305 rotate, and then make the driven bevel gear 306 drive the rotating shaft 1 307 to rotate to switch different convex molds 309, and at the same time start the motor 2 313 to make the rotating shaft 2 311 rotate to switch the corresponding groove 314, and then start the cylinder 1 301 to make the movable table 302 downward and thereby drive the convex mold 309 downward, cooperate with the groove 314 to process the paper corner protectors that need to be bent into different shapes, and two sets of bending devices 3 are set to perform the bending operation of two sets of paper corner protectors at the same time. By setting up the bending device 3, it is convenient to switch the convex molds 309 and the corresponding shapes. The corresponding grooves 314 are used to process paper corner protectors that need to be bent into different shapes, and two groups of paper corner protectors can be processed at the same time, which effectively improves the applicability of the equipment. In addition, by setting the fixing device 4, before the bending operation, the cardboard is first placed on the four groups of rubber bags 45 on the same side, and the cylinder 2 47 is started to make the movable box 43 drive the exhaust pipe 44 to move up and down along the slide 48 to adapt to cardboards of different thicknesses. The air pump is used to draw negative pressure inside the negative pressure box 41, and the suction port 46 generates negative pressure through the hose 42, the movable box 43 and the exhaust pipe 44 to adsorb the cardboard. The negative pressure adsorption makes the cardboard weakly fixed. By setting the fixing device 4, the cardboard is subjected to negative pressure adsorption to make it weakly fixed. The cardboard will not be easily moved due to no fixation, nor will it be affected by the bending of the cardboard due to too firm fixation. This effectively improves the stability of the equipment.
