While pressing the hollow plate, the hot cutter 8 also moves downward to cut the bending groove of the hollow plate. After the cutting is completed, the mounting plate 7 is raised, and the hot cutter 8 will rise first. When the sliding frame 14 is raised, the reaction force of the return spring 16 pushes the disassembly frame 15 downward, so that the scraper 20 can scrape away impurities on the surface of the driving device 9. This structure is simple and convenient for cleaning the surface of the driving device 9, thereby improving the bending efficiency of the plastic hollow plate, wherein the cleaning box 18 and the cleaning box 2 19 have the same internal structure, and a damper is installed inside the return spring 16.

[0022] like Figure 1 and Figure 4 As shown, one side of the disassembly frame 15 is threadedly connected with a fixing bolt 17, and one end of the fixing bolt 17 is threadedly connected to one side of the sliding frame 14. By loosening the fixing bolt 17, the restriction of the disassembly frame 15 is released, and then the disassembly frame 15 is rotated, thereby facilitating the cleaning of the scrapers 20 on the cleaning box 1 18 and the cleaning box 2 19.

[0023] like Figure 1As shown, one side of the workbench 1 is rotatably connected to a bending cylinder 3, the output end of the bending cylinder 3 is rotatably connected to a bending plate 4, one side of the bending plate 4 is rotatably connected to one side of the workbench 1, and by turning on the bending cylinder 3, the bending plate 4 is bent toward the center plate along the center of the axis of one side of the workbench 1.

[0024] like Figure 1 and Figure 2 As shown, a driving device 9 is fixedly installed on the other side of the workbench 1, and the output end of the driving device 9 is connected to a driving roller 11, and the outer wall of the driving roller 11 is connected to a driving belt 10.

[0028] When bending the plastic hollow board, first place the plastic hollow board on the transmission belt 10, turn on the driving device 9, and make the driving roller 11 drive the transmission belt 10 to transmit, so as to transport the plastic hollow board to the bottom of the support frame 2, and then press the cylinder 6 to move the mounting plate 7 downward, and its sliding frame 15 and the disassembly frame 14 are pressed on the hollow board, and the return spring 16 is squeezed and deformed. While pressing the hollow board, the hot cutting knife 8 also moves downward to cut the bending groove of the hollow board. After the cutting is completed, it is raised. The mounting plate 7 and the hot cutting knife 8 will rise first. When the sliding frame 14 rises, the reaction force of the reset spring 16 pushes the disassembly frame 15 downward, so that the scraper 20 can scrape away the impurities on the surface of the driving device 9. Then, the transmission belt 10 is turned on to move the bending groove of the plastic hollow plate to the position between the bending plate 4 and the workbench 1. The pressure cylinder 12 is turned on to press the pressure plate 13 against the plastic hollow plate, and the bending cylinder 3 is turned on to complete the bending of the plastic hollow plate.
