Some used printing plates can be recycled and put into use after a series of processing steps such as cutting and cleaning. Recycled printing plates may have various defects, such as bends or gaps at the corners of the printing plates. Therefore, cutting equipment is needed to cut the four sides of the printing plates to ensure the flatness of the printing plates. However, nowadays, when staff use cutting equipment to cut printing plates, because the printing plates have four sides, after the staff cuts one side of the printing plates, they need to rotate the printing plates and then cut the other side of the printing plates. The process of cutting the four sides of the printing plates requires the staff to adjust the printing plates three times. The adjustment process is time-consuming and labor-intensive, which reduces the cutting efficiency of the printing plates. Utility Model Content

The supporting legs 6 can support the fixing frame 1, and when the printing plate is placed on the moving plate 2 and cut, the waste cut from the printing plate can be put into the collecting box 62 for collection.
[0014] like Figure 1 As shown, a slideway 5 is provided on the inner side of the fixed frame 1, and a slider slidably connected to the inner side of the slideway 5 is fixed on the movable plate 2; a connecting block 27 is fixed on the bottom of the movable plate 2, and a screw rod 41 is rotatably connected to the inner side of the fixed frame 1. A motor 4 for driving the screw rod 41 is provided on the fixed frame 1, and the connecting block 27 is threadedly connected to the screw rod 41. The motor 4 is a servo motor, and the main body of the motor 4 is fixed to the fixed frame 1 through a bearing block, and the rotating shaft of the motor 4 is fixed to one end of the screw rod 41. After the motor 4 is started to drive the screw rod 41 to rotate, the connecting block 27 can move left or right (in degrees) on the inner side of the fixed frame 1. Figure 1 The connecting block 27 can drive the moving plate 2 to move, and the slider on the moving plate 2 cooperates with the slideway 5 to increase the stability of the moving plate 2 when it moves.
[0015] like Figure 1 and Figure 2 As shown, both sides of the pressing plate 22 are fixed with a No. 1 automatic telescopic rod 24, and the telescopic end of the No. 1 automatic telescopic rod 24 is fixed with a cleaning brush 25, and the bottom of the bristles on the cleaning brush 25 is slightly lower than the bottom of the pressing plate 22. When the pressing plate 22 presses down and fixes the printing plate on the movable plate 2, the bristles on the cleaning brush 25 contact the top surface of the printing plate. When the printing plate is cut by the cutter 71, the corresponding No. 1 automatic telescopic rod 24 can be started (when the left side of the printing plate is cut, the No. 1 automatic telescopic rod 24 located on the left side of the pressing plate 22 is started, and when the right side of the printing plate is cut, the No. 1 automatic telescopic rod 24 located on the right side of the pressing plate 22 is started) to move the cleaning brush 25 away from the pressing plate 22, and then push the cut part of the printing plate off from the movable plate 2 to complete the cleaning of the waste.
[0016] like Figure 1 As shown, the fixed end of the hydraulic rod 72 is fixed to the top of the fixed plate 7, the telescopic end of the hydraulic rod 72 is fixed with a lifting plate 73, and the cutter 71 is fixed to the bottom of the lifting plate 73. After the hydraulic rod 72 is started, the hydraulic rod 72 can drive the cutter 71 to move downward through the lifting plate 73 to complete the cutting of the printing plate.
[0017] like Figure 1 and Figure 2As shown, the top of the movable plate 2 is provided with two symmetrical grooves, the pressing plate 22 is located between the two grooves, a No. 2 automatic telescopic rod 3 is fixed in the groove, a moving bar 31 is fixed to the telescopic end of the No. 2 automatic telescopic rod 3, and the top surface of the moving bar 31 is flush with the top surface of the movable plate 2. When the two sides of the printing plate are cut, if the staff needs to adjust the position of the printing plate, the No. 2 automatic telescopic rod 3 can be started to move the moving bar 31 upwards and lift the printing plate upwards, so that the staff can adjust the position of the printing plate after taking the printing plate; a battery (the battery is not shown in the figure) is provided at the bottom of the movable plate 2 to supply power to the two No. 2 automatic telescopic rods 3.

[0019] When in use, the staff puts the printing plate on the top of the movable plate 2 and starts the electric telescopic rod 23. The fixed end of the electric telescopic rod 23 is fixed on the connecting plate 21, and the telescopic end of the electric telescopic rod 23 is fixed to the top of the pressing plate 22. The connecting plate 21 is set in an L shape. After the staff makes one side of the printing plate abut against the inner side of the connecting plate 21, the printing plate can be positioned to avoid the printing plate from tilting. After the electric telescopic rod 23 is started, the pressing plate 22 can be started to move downward to press the printing plate down and fix it, and then the movable plate 2 is moved toward the position of the cutter 71, so that one side of the printing plate After the part to be cut is under the cutter 71, the hydraulic rod 72 drives the cutter 71 to move downward to cut the printing plate. Then, after the cutter 71 moves upward and resets, the movable plate 2 continues to move in the previous direction, so that the part to be cut on the other side of the printing plate is located under the cutter 71, and the cutter 71 moves downward to complete the cutting of the printing plate; then the pressing plate 22 moves upward, and after the printing plate is no longer fixed, the staff rotates the printing plate 90°. After adjusting the printing plate, the movable plate 2 can be moved in the opposite direction, so that the cutter 71 completes the cutting of the other two sides of the printing plate.
[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
