[0033] A collecting assembly 6, wherein the collecting assembly 6 is arranged in the top cover 3;

[0034] The punching assembly 5 includes a cross frame 5-1, which is fixed in the rectangular opening 4. A long groove 5-2 is provided at the bottom of the cross frame 5-1, and a plurality of round holes 5-3 are provided in the long groove 5-2. A base frame 5-4 is provided at the bottom of the stand 1. A positioning screw 5-5 is rotatably connected to the inner side of the base frame 5-4. A pair of slideways 5-6 are provided on the inner side of the base frame 5-4. A moving seat 5-7 is slidably connected to the slideway 5-6. The moving seat 5-7 is connected to the positioning screw 5-5 through threaded cooperation. A punching hydraulic cylinder 5-8 is installed at the bottom of the moving seat 5-7. A punching head 5-9 is provided at the output end of the punching hydraulic cylinder 5-8. The positioning screw 5-5 is driven to rotate by a motor. A pair of positioning rollers 5-10 are rotatably connected to the inside of the rectangular opening 4. The positioning rollers 5-10 are all controlled to rotate by the motor.

[0035] In the present embodiment, in order to achieve the effect of multi-position punching of the plate body of the distribution cabinet, a punching assembly 5 is designed, and a cross frame 5-1 is fixed inside the rectangular opening 4, and a long groove 5-2 and a circular hole 5-3 for punching are opened at the bottom of the cross frame 5-1, and a hollow structure base frame 5-4 is also fixed at the bottom, and positioning screws 5-5 and slideways 5-6 are respectively arranged on both sides of the base frame 5-4, and a movable seat 5-7 is connected to the slideway 5-6 and the positioning screw 5-5, and a punching hydraulic cylinder 5-8 and a punching head 5-9 are installed at the bottom of the movable seat 5-7. The position of the punching hydraulic cylinder 5-8 can be quickly positioned by controlling the moving seat 5-7 through the positioning screw 5-5, and the punching head 5-9 can pass through the circular hole 5-3 to punch, and two positioning rollers 5-10 controlled by motors are arranged in the rectangular opening 4, which can rotate to drive the plate body to move and quickly position it to the punching position.

[0036] Furthermore, the collecting assembly 6 includes a plurality of docking tubes 6-1, which are fixed at the top of the top cover 3. The docking tubes 6-1 are connected to the inside of the top cover 3. A cleaning port 6-2 is provided on the side surface of the top cover 3. A side cover 6-3 is installed in the cleaning port 6-2. A clamping roller 6-4 is rotatably connected in the top cover 3. An air pipe 6-5 is installed at the top of the top cover 3. A plurality of air nozzles 6-6 are provided on the surface of the air pipe 6-5. The air nozzles 6-6 have a certain inclination angle.

[0037] In this embodiment, in order to collect the waste dropped when punching the mobile phone, a collection component 6 is designed. A plurality of docking tubes 6-1 are arranged on the top of the top cover 3 and communicate with the inside of the top cover 3. After the punching head completes the punching, it continues to move upward so that the dropped waste can enter the inside of the top cover 3. An air pipe 6-5 and a plurality of air nozzles 6-6 are installed. A blowing device can be connected so that the air nozzles 6-6 can blow the waste to drop it and ensure that it drops into the inside of the top cover 3. A cleaning port 6-2 is opened on one side of the top cover 3 and a side cover 6-3 is installed, which can be opened for cleaning the inside.

[0038] Furthermore, it also includes a correction component 7, which is arranged on the top cover 3. The correction component 7 includes a pair of horizontal openings 7-1, which are respectively opened at both ends of the top cover 3 and the surface of the stand 1. The top cover 3 is fixedly connected with a pair of guide frames 7-2, and the guide frame 7-2 is located on one side of the horizontal opening 7-1. A correction screw 7-3 is rotatably connected inside the guide frame 7-2, and the correction screw 7-3 is controlled to rotate by a motor. A movable frame 7-4 is slidably connected inside the guide frame 7-2, and the movable frame 7-4 is connected to the correction screw 7-3 by threaded cooperation. The bottom of the movable frame 7-4 is rotatably connected with a correction roller 7-5.

[0039] In this embodiment, in order to achieve the effect that the plate body of the distribution cabinet can maintain linear movement, a correction component 7 is designed. Two horizontal openings 7-1 are opened on the surface of the top cover 3 and the stand 1. A guide frame 7-2 is arranged on the surface of the top cover 3 on one side of the horizontal opening 7-1, and a correction screw 7-3 and a moving frame 7-4 are installed inside. The correction screw 7-3 can control the moving position of the moving frame 7-4. A correction roller 7-5 is rotatably connected to the bottom of the moving frame 7-4, which can be fitted on both ends of the plate body to keep the plate body moving in a straight line.

[0040] Furthermore, the position of the butt-joint pipe 6-1 corresponds to the position of the circular hole 5-3 and is located at the same axis, and the inner diameter of the butt-joint pipe 6-1 is the same as the inner diameter of the circular hole 5-3.

[0041] In this embodiment, through the coaxial position, the bottom of the butt-joint tube 6 - 1 fits with the surface of the plate body during punching, ensuring that the punching head 5 - 9 can enter the butt-joint tube 6 - 1 and send the waste into the top cover 3 .

[0042] Furthermore, one side of the top cover 3 transitions downward to form a concave structure.

[0043] In this embodiment, the concave structure allows the incoming waste to be concentrated in the concave area, making it easier to clean.

[0044] Furthermore, the upper end surfaces of the positioning rollers 5 - 10 and the surface of the stand 1 are located at the same plane height.

[0045] In this embodiment, the positioning rollers 5-10 are at the same height as the surface of the stand 1, so that the plate body can be prevented from being squeezed during punching during transportation.

[0046] When punching is required, according to the width of the plate, drive the correction screw 7-3 to adjust the position of the correction roller 7-5. After the plate is corrected to the appropriate position, start the positioning roller 5-10 to start conveying the plate to adjust the position. After reaching the position, start the telescopic cylinder 2 to drop the top cover 3 and make the bottom fit with the surface of the plate. Then start the positioning screw 5-5 to adjust the position of the punching hydraulic cylinder 5-8. After reaching the position, start the punching hydraulic cylinder 5-8 to punch through the punching head 5-9. The waste generated by the punching enters the top cover 3 through the docking tube 6-1, and start the air nozzle 6-6 to blow the waste into the top cover 3 by blowing air. Then adjust the position again to continue punching. The waste can be cleaned by opening the side cover 6-3.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
