[0033] Working principle: When using the paper tray production trimming device, program the PLC control switch according to the size data of the paper tray, place the paper tray on the table 1, and make one side of the paper tray contact the push plate 14. At this time, the PLC control switch will start the second electric push rod 13, so that the movable end of the second electric push rod 13 will move the set stroke according to the set program, so that the push plate 14 can push the side of the paper tray to be cut to the notch 6, and then start the motor 10, so that the output end of the motor 10 drives the bidirectional screw The rod 9 rotates, so that the moving block 11 on the bidirectional screw 9 moves along the moving groove 7, thereby driving the two clamping plates 12 to contact the surfaces on both sides of the paper support, thereby clamping the paper support and fixing the position of the paper support on the table body 1. At this time, the first electric push rod 3 is started again, and the movable end of the first electric push rod 3 drives the cutting knife 5 installed at the bottom end of the mounting block 4 to move downward, so that one end of the cutting knife 5 passes through the paper support and enters the notch 6, so that the rough edge of the paper support that needs to be cut will be cut off by the cutting knife 5, thereby automatically completing the paper support. The cutting operation of the paired paper tray rough edges avoids the need for the operator to hold the cutting tool to cut the rough edges of the paper tray, thereby reducing the labor intensity and improving the overall processing efficiency of the paper tray. Secondly, when the paper tray rough edges are cut by the cutting knife 5, the waste will slide into the slot 6, so that the waste will enter the collection box 15 from the slot 6 and be collected, avoiding the waste from accumulating on the table body 1. The collection of the waste inside the collection box 15 can be seen through the transparent observation window 20. When there is a lot of waste inside the collection box 15, it is necessary to When processing, place the waste holding basket at the lower end of the collection box 15, twist the butterfly bolt 19, and separate one end of the butterfly bolt 19 from the collection box 15. The box cover 18 can be rotated by the hinge 17 to expose the through slot 16. In this way, the waste in the collection box 15 will slide down through the through slot 16 and enter the waste holding basket, so that the operator can concentrate on processing. Then, the box cover 18 is rotated by the hinge 17 to cover the through slot 16 again, so that the collection box 15 can continue to collect waste.
