Description

Technical Field

[0001] The utility model relates to the technical field of paper bag hemming, and specifically, to a handle paper bag hemming mechanism. Background Art

[0002] During the production process of paper bags, the left edge of the paper used as raw material needs to be folded towards the right first, and then the folded edge position is glued and enters the next process for further processing.

[0003] According to a paper bag rapid hemming device disclosed in Chinese Patent CN202221552768.6, this application drives the hemming baffle to move back and forth through the first cylinder, and the screw rod rotates to drive the nut block to move left and right, so that the second cylinder moves, and the hemming baffle and the hemming push block move to the hemming position at the same time, so that the hemming position can be adjusted; through the setting of the third cylinder and the pressing plate, the pressing plate presses on the paper bag cardboard to fix it for subsequent hemming; by setting the edges of the baffle and the push block to be rounded, it is possible to avoid damaging the paper bag during hemming; through the setting of the hand-turning knob and the anti-slip groove, it is convenient to rotate the screw rod and avoid slipping of the hand during rotation, which can effectively solve the problem of inconvenient adjustment of the hemming position according to different paper bag sizes. The existing paper bag rapid hemming device conveys the paper bag cardboard to the hemming place through a conveyor belt for processing. Since the conveyor belt lacks limitation on the paper bag cardboard, the paper bag cardboard is prone to deviation and skew during movement, which brings trouble to hemming. At the same time, the existing paper bag rapid hemming device needs to adjust the positions of the hemming baffle and the hemming push block successively, which is time-consuming and has a slow adjustment efficiency.
