[0031] When it is necessary to punch a cardboard box;

[0032] First, place the cardboard on the punching workbench 1. Subsequently, the hydraulic expansion rod 18 is started to drive the punching ring 17 to move downward for punching. At the same time, start the motor 8. The start of the motor 8 drives the motor gear 7 to rotate. The rotation of the motor gear 7 drives the gear 9 to rotate. The rotation of the gear 9 drives the threaded rod 10 to rotate. The rotation of the threaded rod 10 drives the threaded sleeve 11 to move. The movement of the threaded sleeve 11 drives the second ring part 16 to move. The second ring part 16 moves upward to squeeze the cardboard. The upward movement of the second ring part 16 drives the connecting rod 13 to move upward. The upward movement of the connecting rod 13 drives the limit pin 15 to move upward and pierce into the material removed by the punching.

[0033] Secondly, by starting the motor 8, the start of the motor 8 drives the motor gear 7 to rotate. The rotation of the motor gear 7 drives the gear 9 to rotate. The rotation of the gear 9 drives the threaded rod 10 to move. The rotation of the threaded rod 10 drives the threaded sleeve 11 to move downward. The downward movement of the threaded sleeve 11 drives the second ring part 16 to move downward. The downward movement of the second ring part 16 drives the limit pin 15 to move downward. The downward movement of the limit pin 15 drives the residual waste on the limit pin 15 to move downward to near the first ring part 12. The limit pin 15 finally lies at the lower end of the first ring part 12, thereby moving the residual waste onto the first ring part 12. Subsequently, start the blower 2. The start of the blower 2 blows air through the air blowing head 5 onto the residual waste, and blows the residual waste into the interior of the drawer 4 for collection.

[0034] When it is necessary to collect the residual waste inside the drawer 4;

[0035] First of all, pull the handle 3 to move through an external force. The movement of the handle 3 drives the drawer 4 to move to open the drawer 4, so as to recycle the residual waste after punching the cardboard box board.

[0036] By setting the punching component and the cleaning component, the punching component uses the punching ring 17 and the second ring part 16 to punch simultaneously from the upper and lower directions, which can avoid the phenomenon that when punching only from top to bottom, the quality of the punched holes is low when encountering a relatively thick cardboard box. That is, double-sided punching can improve the punching quality, and the residual waste from punching can be ejected from the first ring part 12 and then blown into the interior of the drawer 4 by the air blowing head 5 for collection, avoiding the residual waste from punching affecting the subsequent punching of the cardboard box.

[0037] By setting the drawer 4 in the cleaning component, the drawer 4 can temporarily store the waste it cleans inside the drawer 4. When recycling is needed, only need to pull the handle 3 to drive the drawer 4 to move, which is convenient for the collection of waste.

[0038] Working principle:

[0039] When it is necessary to punch the cardboard box;

[0040] First of all, place the cardboard on the punching workbench 1. Subsequently, start the hydraulic expansion rod 18 to drive the punching ring 17 to move downward for punching. At the same time, start the motor 8. The motor 8 drives the motor gear 7 to rotate. The motor gear 7 drives the gear 9 to rotate. The gear 9 drives the threaded rod 10 to rotate. The threaded rod 10 drives the threaded sleeve 11 to move. The threaded sleeve 11 drives the second ring part 16 to move. The second ring part 16 moves upward to squeeze the cardboard. The upward movement of the second ring part 16 drives the connecting rod 13 to move upward. The upward movement of the connecting rod 13 drives the limit pin 15 to move upward and pierce into the material removed by punching.

[0041] Secondly, by starting the motor 8, the motor 8 drives the motor gear 7 to rotate. The motor gear 7 drives the gear 9 to rotate. The gear 9 drives the threaded rod 10 to move. The threaded rod 10 drives the threaded sleeve 11 to move downward. The threaded sleeve 11 drives the second ring part 16 to move downward. The second ring part 16 drives the limit pin 15 to move downward. The limit pin 15 drives the residual waste on the limit pin 15 to move downward to near the first ring part 12. The limit pin 15 finally lies at the lower end of the first ring part 12, thereby moving the residual waste onto the first ring part 12. Subsequently, the blower 2 is started.

[0042] When it is necessary to collect the residual waste inside the drawer 4;

[0043] First of all, by an external force, the handle 3 is pulled to move. The movement of the handle 3 drives the drawer 4 to move until the drawer 4 is opened.
