Method for preventing box cover from rebounding in paper box processing

Abstract

The invention belongs to the technical field of packaging box processing, and discloses a method for preventing a box cover from rebounding in paper box processing. A paper box comprises an upper cover and a lower cover, two cover bodies are input when being in a closed state, a paper box conveying path is provided, and an opening station, a non-return station and a mold taking station are sequentially arranged along the conveying path, wherein the upper cover is opened to a first angle on the opening station, a first blocking piece extends into a box opening, and the tail end of the blocking piece extends to the non-return station; in the non-return station, a pushing piece is arranged on the front face of the box opening to bear the upper cover, then the pushing piece is pushed towards the upper cover to enable the upper cover to be turned to a second angle, and then a non-return assembly extends downwards from the upper portion of the box opening; and the upper cover is kept to be greater than or equal to 90 degrees at the mold taking station. A sliding linear cover turning scheme of the box cover in the prior art is omitted and improved into a sectional cover turning scheme, so that the rebounding prevention effect is more stable, and the material damage rate is lower.

Description

technical field [0001] The invention belongs to the technical field of packaging processing, in particular to a method for preventing springback of a box cover in carton processing. Background technique [0002] Full-open packaging boxes are widely used in cigarette packs, and gradually mature technology makes the processing quality and processing efficiency of full-open packaging boxes more and more stable. [0003] The existing full-open packaging method is: first prepare the outer box, that is, the carton block with the outer paper fully covering the inner box, and then use the carton opener to trim the three sides of the carton block and take out the inner box. internal model. Among them, the inner mold is collected and recycled, and the opened cartons are then sorted and sorted. In this production method, the three-sided knife trimming process is now integrated into a box opening machine to realize. A cutter is arranged on the traveling path of the outer box to cut th...

Problems solved by technology

[0005] (1) The safety of sheet metal parts is poor, and there are construction risks

[0006] (2) The guide efficiency of the spiral structure is limited: because the edge of the box cover is sharp and angular, and the thrust of the box comes from the lower cover of the box. If the upper cover of the box bears the brunt of the edges and corners, the edges and corners impact the spiral part and will be reversed. force, if too much force will tear the carton

[0007] (3) When changing orders, it is necessary to re-adjust arc-shaped baffles with different lengths or different spiral densities
