Automatic paper collection deviation correcting device of box pasting machine

Abstract

The invention discloses an automatic paper-receiving and deviation-correcting device for a folder-gluer, which comprises a frame, on which a rotatable sheave rotating shaft is supported; At least one delivery deviation correction groove is arranged on the paper delivery deviation correction groove, at least one section of the front groove wall and the rear groove wall of the paper delivery deviation correction groove is involute curved surface; The front side of the deviation correcting sheave for delivery of paper is fixedly provided with a deviation correcting fixed support plate, and a movable cardboard is arranged above the deviation corrected fixed support plate. The distance from two different points on the involute curved surfaces of the front and rear groove walls of the paper delivery correction groove from the inside to the outside and the rotation center of the paper delivery correction sheave increases gradually. The deviation correction device can automatically realize the alignment correction of the sticky mouth of the carton board and the continuous transfer of the carton board. It has the characteristics of compact and reasonable structure and high production efficiency.

Description

technical field [0001] The invention relates to a carton forming machine, in particular to a device for correcting and rectifying cardboard during the conveying process of a carton folder-gluer. Background technique [0002] With the rapid development of the printing industry, box-gluing process equipment is also widely used in the production and processing of packaging boxes for food, medicine, wine and industrial products. The folder-gluer is becoming more and more advanced, and the structure and style of the pasted cartons has become more diverse and complicated. It is no longer limited to the common four-corner and hexagonal packaging boxes, but also includes a large number of low-height packaging boxes. , such as a low waist hook bottom box. [0003] The automatic folder-gluer can place the semi-finished carton boards that have been cross-cut at the paper feeding position, and the cardboards will be transported to the back section after completing the processes of crea...

Problems solved by technology

Especially for a large number of cartons with wide surface and low box height (for example, the box height is less than 8cm), the misalignment or staggering of the front and rear conveying edges of the carton board blanks will not only cause the cartons to stick to the mouth Skewing and misalignment will cause the cartons to have low bonding fastness, easy to crack or degumming, and the carton slabs will be torn and damaged at the fold line of the waist when they are transported and aligned, which directly affects the quality of the box-gluing box and the rate of the box-gluing box. improve

[0005] The alignment device of the existing automatic folder-gluer is to align the front and rear edges of the carton slab along the horizontal conveying direction to achieve deviation correction. The short waist folding line along the conveying direction is easy to cause snapping and tearing, resulting in glued box waste; at the same time, the front and rear edges of this kind of low waist carton during the conveying process are mostly concave and convex folding lines, and the existing deviation correction Mechanism snapping boards often act on the edge of the protruding fold line, which increases the snapping and tearing effect on the low-waist folding line, and the snapping return of the reciprocating snapping of the existing deviation correction mechanism will also affect the glued box The production efficiency of the machine is difficult to achieve the combination and coordination of continuous conveying and alignment correction actions
