Punching device for packaging cardboards

Abstract

The invention discloses a punching device for packaging cardboards. The punching device includes a bottom plate, wherein an H-shaped bracket, a support plate, a vertical plate and a support frame arearranged on the bottom plate; U-shaped plates are symmetrically distributed on the support frame; a pressure roller is arranged between the U-shaped plates and movably connected with each U-shaped plates; a conveying roller assembly and a material receiving groove are arranged between the U-shaped plates; a drive motor is arranged on the vertical plate; the drive motor is connected with a turntable; a drive plate is eccentrically connected with the turntable; a mounting plate is slidably connected with the vertical plate; a swinging rod is arranged between the mounting plate and the drive plate; an L-shaped fixing block is arranged on the drive plate; a punch head is arranged on the L-shaped fixing block; a transmission wheel is movably connected with the H-shaped bracket; a material receiving motor is arranged on the support plate; the receiving motor is connected with a drive board; drive pins are arranged on the drive plate; stop grooves are circumferentially distributed on the outer circumference of the transmission wheel; and the stop grooves correspond to the drive pins. The punching device has the advantages of compact structure, flexible connection, good punching effect, continuous order, automatic and convenient usage, and more in line with the punching requirements of the cardboards.

Description

technical field [0001] The invention belongs to the technical field of cardboard processing, in particular to a punching device for packaging cardboard. Background technique [0002] During the cardboard manufacturing process, it is necessary to punch holes on the surface of the cardboard, so that the objects that need heat dissipation and ventilation can have a good ventilation effect after packaging, and avoid the phenomenon that the objects are damaged because they cannot contact the air. [0003] There are certain defects in the existing cardboard punching machine in the process of use: each time the hole is punched, the cardboard needs to be moved manually, the continuous punching work cannot be completed, the punching efficiency is low, and the labor intensity of the operator is high; and adjacent holes The spacing between them is not easy to control and is uneven, which cannot meet the production needs. Contents of the invention [0004] The purpose of the present ...
