High-speed corrugated paper multi-color flexographic printing slotting die-cutting glue box linkage line

Abstract

The invention provides a high-speed corrugated paper multi-color flexographic printing, slotting, die-cutting and box gluing linkage line. The high-speed corrugated paper multi-color flexographic printing, slotting, die-cutting and box gluing linkage line comprises a pressing-free paper feeding mechanism, a printing mechanism installed at the rear end of the pressing-free paper feeding mechanism,a slotting mechanism installed at the rear end of the printing mechanism, a die-cutting mechanism installed at the rear end of the slotting mechanism, a box pasting mechanism installed at the rear endof the die-cutting mechanism and a counting and discharging mechanism installed at the rear end of the box pasting mechanism. According to the high-speed corrugated paper multi-color flexographic printing, slotting, die-cutting and box gluing linkage line, the automatic degree is high; automatic paper feeding, printing, slotting, die-cutting, box pasting and folding and paper discharging countingcan be realized; a front end of the linkage line adopts the pressing-free paper feeding mechanism to perform non-pressure paper feeding, and damage of the corrugation strength in the paper feeding process can be avoided; a plurality of groups of forming roller tapered type box gluing forming structures are adopted, the forming speed is high, the quality is good, and the rejection rate of a product can be greatly reduced; and the counting and discharging mechanism is arranged at the tail part of the linkage line, counting, stacking and discharging of paperboards after box pasting can be realized, and ceaseless transferring of the paperboards according to designed piece number is realized.

Description

technical field [0001] The invention relates to the technical field of cardboard printing equipment, in particular to a high-speed corrugated paper multi-color flexo printing slotting, die-cutting and box-gluing linkage line. Background technique [0002] Existing slotting and die-cutting machines for flexographic printing generally only include a paper feeding part, a printing part and a slotting part. During operation, the cardboard is transported to the printing part through the paper feeding part. Transfer to the printing plate attached to the printing plate roller, the printing plate roller and the embossing roller are rolled and pulled, and the cardboard to be printed is printed, and then sent to the next overprinting device. After multiple color printing, the multi-color printing pattern It is printed on cardboard, and finally processed into the products required by customers by the slotting department. [0003] The existing flexographic printing industry usually enc...

AI Technical Summary

Problems solved by technology

[0003] The existing flexographic printing industry usually encounters the following major technical bottlenecks: (1) It is impossible to control the damage to the compressive strength of the cardboard during the printing and conveying process after the corrugated paper is conveyed. Often, the cardboard is glued after printing by the equipment, and the strength of the cardboard is reduced by 20%. -40%, in order to solve this problem, the end customers of the equipment need to increase the strength of corrugated raw materials to meet the requirements of carton packaging, which undoubtedly increases a lot of finished products and causes a great waste of resources; (2) the normal operating speed of the equipment and The printing quality is uncontrollable. In the current harsh environment of industry competition, the operating cost of the equipment is limited, but the mechanical design speed of the equipment cannot achieve a breakthrough. The design of the main adsorption transmission platform and the associated gear transmission is unreasonable. Improving and sacrificing printing quality, it is impossible to achieve both sides; (3) The printed corrugated paper needs to be transferred to additional equipment for gluer folding after slotting, which cannot achieve continuous production, and during the gluer folding process, The shape benchmark of the carton forming cannot be controlled. After the cardboard is glued and folded, the cardboard is prone to bursting or bell mouth. When the carton is flattened and used to install the finished product, the top and bottom are not aligned, which cannot be effectively corrected, resulting in a high product scrap rate; (4) After The finished box after the gluer is folded cannot be counted and detected online
