Carton mark pressing device with cartons pasted accurately

Abstract

The invention discloses a carton mark pressing device with cartons pasted accurately and belongs to the field of carton mark pressing devices. The carton mark pressing device with cartons pasted accurately comprises an air cylinder, a piston rod, a fixed connecting piece and an upper mark pressing plate. The air cylinder is connected with the fixed connecting piece fixedly installed on the side face of the upper mark pressing plate through the piston rod. Two pairs of sharp edges are symmetrically arranged at the bottom of the upper mark pressing plate, and a cavity with the cross section being rectangular is defined by the two pairs of sharp edges. A lower mark pressing plate is arranged below the upper mark pressing plate. Grooves are formed in the positions, corresponding to the two pairs of sharp edges, on the lower mark pressing plate, the grooves are matched with the sharp edges, a convex rib with the cross section being rectangular is formed between the two grooves, and the convex rib is matched with the cavity. The carton mark pressing device with cartons pasted accurately not only can solve the problem that cartons are prone to dislocation in the carton pasting process and guarantee that the cartons are formed accurately but also can avoid that different sinking degrees need to be adjusted because of different kinds of corrugated paper, and is wide in application range.

Description

technical field [0001] The invention relates to a carton creasing device, in particular to a carton creasing device with precise pasting. Background technique [0002] With the continuous development of the economy, the demand for carton packaging is increasing, involving more and more industries, and the packaged goods are widely used in advanced assembly line production operations and automatic box packaging, so the geometric dimension accuracy of paper bonding molding is more demanding. In some industries, such as tobacco and pharmaceutical industries, due to the high degree of automation, the requirements for cartons must be almost insignificant, otherwise it will affect the automated flow operation, cause production failure, and bring greater losses. [0003] The creasing device is an important part of the printing slotting machine. The corrugated cardboard is pressed out by the creasing device, and the corrugated cardboard is folded and formed by the scoring line. Ther...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the defect that the dark lines of corrugated paper in the prior art are easily dislocated due to the concave design method, and to provide a carton indentation device with precise pasting. By adopting the technical solution of the present invention, Using reverse thinking to change the concave design into a convex design can not only solve the problem of easy misalignment of the carton gluer, ensure the accuracy of the carton forming, but also avoid the need to adjust different concave degrees due to different corrugated paper, and has a wide range of applications.
