Double-side labeling machine for packaging

Abstract

The invention discloses a double-side labeling machine for packaging, and belongs to the technical field of double-side labeling machines. The double-side labeling machine for packaging comprises a rack, two first fixed plates are fixedly connected to the top of the rack, and a conveying belt is jointly in transmission connection between the two first fixed plates. According to the double-side labeling machine for packaging provided by the invention, when double side faces of a carton are labeled every time, the periphery of the carton is positioned at the accurate labeling position through a positioning mechanism and a pressing mechanism, the carton is prevented from deviating in the conveying process, the pressing mechanism is used in cooperation to press an L-shaped clamping block to clamp the carton, it is guaranteed that a first rack can drive a first gear and the L-shaped clamping block to rotate every time, the L-shaped clamping block is completely separated from the side wall of the carton and is matched with a front labeling device and a rear labeling device to label at the same time, when the L-shaped clamping block is separated, the accuracy of the front position and the rear position of the carton can still be kept, the L-shaped clamping block is prevented from making contact with the labeling machine, the labeling machine is protected, and the requirement for labeling the whole side wall of the carton can be met.

Description

Technical field [0001] The present invention relates to the technical field of bilateral labeling machines, in particular a bilateral labeling machine for packaging. Background technique [0002] The labeling machine is a device that passes a contained sticker tag (paper or metal foil) in PCB, product, or specified packaging. The labeling machine is an indispensable component of modern packaging. At present, my country has la la launches. The type is gradually increased, and the technical level has also improved, from the backwardness of manual, semi-automatic labeling, and stepping to automated high-speed labeling machine occupies the pattern of the market. [0003] The prior art discloses inventive patents in some bilateral labeling machines, Patent Application No. CN201810943931.3, China Patent, which discloses two-sided labeling of carton, including rack, transfer assembly, box fixation And the two labeling components, the labeling assembly includes a horizontal support plate...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a double-sided labeling machine for packaging, to solve the problem in the background technology mentioned above. The labeling machine is located on both sides of the carton, and the positioning mechanism needs to wrap the carton when the carton is fully positioned. As a result, when the labeling machine is on the edge of the carton or the labeling range is large, the labeling plate of the labeling machine will be in contact with the positioning mechanism. Interference occurs, and after multiple actions, it will cause damage to the labeling board
