Description

Technical Field

[0001] The utility model relates to the technical field of punching, in particular to a punching device for cardboard. Background Art

[0002] Cardboard, also known as board paper, is a thick paper sheet made from various pulps and composed of interwoven fibers. The difference between cardboard and paper is usually distinguished by quantity and thickness. Due to usage needs, after the cardboard is processed, it needs to be punched to facilitate air permeability, heat dissipation and improve ventilation effects.

[0003] The Chinese patent with patent application number 202223445956.1 proposes a cardboard punching device, in which the auxiliary device includes four extension rods, and the four extension rods are fixedly installed on the two side surfaces of the cross plate in a group of two, and the surfaces of the four extension rods are slidably connected with a slide plate, and the bottom surfaces of the four slide plates are hinged with hinge plates, and the hinge plates are hinged with a pressure plate at one end away from the slide plate, and the bottom surface of the cross plate is fixedly installed with two sleeves, and the insides of the two sleeves are slidably connected with support rods, and the ends of the support rods away from the sleeves are fixedly connected to the pressure plate, and the surfaces of the ends of the four extension rods away from the cross plate are fixedly installed with a limit plate, and a spring is fixedly installed between the limit plate and the slide plate. The utility model solves the problem that the existing cardboard punching device cannot reduce the impact on the cardboard when the motor drives the drill bit to rotate and completes the punching operation of the cardboard, thereby easily causing damage to the cardboard.

[0004] However, after the improvement, the above patent still has the problem that after the drilling is completed, many small pieces of paper will remain around, which are difficult to collect and process later. In addition, when a cardboard needs to be punched multiple times, the cardboard needs to be taken out and put back, which easily makes each hole uneven. Utility Model Content
