Since one end of the connecting rod is arranged It is installed in an eccentric position on one side of the rotating wheel, and cooperates with the guiding effect of the inner cavity of the device body on the lifting column. As the rotating wheel rotates, the lifting column is driven by the connecting rod to move vertically back and forth. Then, every time the punching head on the mounting plate below the lifting column contacts the packaging box plate, it will punch it, thereby forming holes on the surface. Cooperating with the movement of the packaging box plate by the conveyor belt, the packaging box plate will move to one side a fixed distance each time it is punched, thereby ensuring the uniformity of the punching gap. Through this linkage structure, continuous punching processing of the packaging box plate can be realized, which not only improves the processing efficiency but also ensures the quality of product punching.

[0018] 2. The utility model installs pressure rods on both sides of the bottom of the mounting plate, and the pressure rods are located above the conveyor belt. Under normal conditions, the pressure plate at the bottom of the pressure rod is lower than the height of the bottom of the punching head. Therefore, during the punching process, the pressure plate will preferentially contact the packaging box plate body. As the mounting plate descends, the spring inside the movable cavity can provide supporting force for the pressure plate, thereby ensuring the fixing effect of the pressure plate on the packaging box plate body. Therefore, the packaging box plate body can maintain a stable state when in contact with the punching head, avoiding the deviation of the punching position.

[0019] 3. The utility model adopts a plug-in positioning structure in the installation structure of the punching head. When replacing the punching head, it is only necessary to take out the positioning pin to make the mounting seat and the mounting plate at the upper end of the punching head lose their limit, and then the punching head can be pulled upward. During installation, it is inserted from the mounting hole at the upper end of the mounting plate, and then the positioning pin is inserted from the corresponding end face into the positioning hole inside the punching head. This structure is convenient and easy to operate, and can also improve the installation firmness of the punching head. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See also Figure 1-4 The utility model provides an embodiment: a punching device for producing paper product packaging boxes, comprising a frame 1, a device body 2 is arranged above the frame 1, and a limited position slide groove 3 is arranged below the inside of the device body 2; and further comprising:

[0027] A mounting plate 4 is arranged inside the limiting slide groove 3, and the mounting plate 4 is slidably connected to the limiting slide groove 3, and a plurality of punching heads 5 distributed in a rectangular array are arranged inside the mounting plate 4;

[0029] The pulley 19 is arranged at the other end of the driving shaft 15 and the front end of one side of the frame 1 , and the two pulleys 19 are connected by a belt 20 .

[0030] When in use, place the packaging box plate on the conveyor belts 11 on both sides, turn on the driving motor 17, and its output shaft drives the driving gear 18 to rotate, and drives the driving shaft 15 to rotate under the meshing with the driven gear 16. One end of the driving shaft 15 drives the upper pulley 19 to rotate through the gearbox, and the belt 20 drives the pulley 19 at one end of the transmission roller 10 to rotate. The tension formed by the two transmission rollers 10 on the conveyor belt 11 causes the conveyor belt 11 to move under the action of friction, thereby realizing the movement of the upper packaging box plate. At the same time, the driving shaft The other end of 15 drives the rotating wheel 14 to rotate. Since one end of the connecting rod 13 is installed at an eccentric position on one side of the rotating wheel 14, the inner cavity of the device body 2 guides the lifting column 12, so that as the rotating wheel 14 rotates, the connecting rod 13 drives the lifting column 12 to move vertically back and forth.
