[0004] However, when a plurality of holes linearly equidistant in a row need to be punched on the folded paper box, since the existing paper box punch lacks positioning of the paper box, it is completely necessary to rely on the workers to control by themselves, and then the phenomenon of deviation is easy to occur, so that the holes in a row are uneven, thereby affecting the appearance of the paper box and subsequent use.Therefore, we propose a paper box production trepanning device.

[0028] A through slot 19 is formed in the lower edge of the side wall of the sliding block 11, and the through slot 19 is in sliding fit with the convex plate 18.

[0029] Working principle: when it is needed to punch the folded carton, the worker places the carton on the upper end of the lower cross beam 7 and the lower die 3, and makes the position of the carton to be punched correspond to the upper die 2, and then rotates the control rod 10 to drive the upper die 2 to move downward, so that the upper die 2 punches the carton, which is a known prior art and will not be described in detail.

[0030] When it is needed to open a plurality of linear equidistant holes on the carton, first, the rotating block 15 is rotated to drive the screw rod 4 to rotate, the screw rod 4 rotates on the connecting block 13 and the fixed block 12, and the screw rod 4 drives the sliding block 11 to move towards the upper die 2 or away from the upper die 2 in the direction of the screw rod 4 and the guide rod 6, the sliding block 11 drives the leverage plate 17, the convex plate 18, the fixed plate 22, the connecting rod 21, the positioning block 5 and the spring 20 to move towards the upper die 2 or away from the upper die 2, the lower end of the positioning block 5 slides on the upper end of the lower cross beam 7 until the distance between the positioning block 5 and the upper die 2 is equal to the distance between the first hole opened on the carton and the next hole to be opened, at which time the rotating block 15 is stopped, the leverage plate 17 and the convex plate 18 are held and the convex plate 18 is lifted upward, the convex plate 18 slides upward in the through slot 19, the convex plate 18 drives the connecting rod 21 and the positioning block 5 connected to the connecting rod 21 to move upward, the connecting rod 21 slides upward in the inner wall of the fixed plate 22, and the positioning block 5 presses the spring 20 connected between the fixed plate 22, then the carton is moved to make the first hole opened on the carton correspond to the positioning block 5, then the convex plate 18 is released, at which time the convex plate 18, the connecting rod 21 and the positioning block 5 automatically move downward under the action of the spring 20, the positioning block 5 is inserted into the first hole opened on the carton, at which time the positioning block 5 can position the carton, then the control rod 10 is continuously rotated to make the upper die 2 punch the carton, and so on, each time a new hole is punched, the new hole is matched with the positioning block 5, so that the worker can easily open a plurality of linear equidistant holes on the carton, which is not only beautiful but also facilitates subsequent use.

[0031] It should be noted that according to the adjustability of the positioning block 5, a plurality of holes with different intervals and equidistance can be formed on the carton, and the applicability is better.

[0032] It should be further noted that the slider 11 also drives the pointing piece 16 to move during the movement, and the pointing piece 16 is attached to the scale line 9 on the side wall of the upper beam 8 to slide, and the cooperation between the pointing piece 16 and the scale line 9 can make the staff more accurately judge the distance between the positioning block 5 and the upper die 2.

[0033] It should be further noted that the friction between the rubber ring 14 and the screw rod 4 can make the screw rod 4 keep a certain fixed state after rotating.
