Impressing device for full-automatic corrugated cardboard box gluer

Abstract

The invention relates to an impressing device for a full-automatic corrugated cardboard box gluer. The impressing device comprises two outer wall plates and two pairs of rubber rollers, wherein the two outer wall plates are fixed on the lower parts of two sides of the machine body; the impressing device comprises movable guide posts, movable side plates, a half support plate, support guide rails, positioning blocks, impressing shafts and impressing wheels; an upper support guide rail and a lower support guide rail are provided with an upper positioning block and a lower positioning block in a sliding way; and an upper impressing wheel and a lower impressing wheel are arranged on the inwards protruding end parts of the upper positioning block and the lower positioning block. By the technical scheme, under the matching action of a pair of impressing wheels in concave-convex shapes, original punched pre-impression on a folding part of a corrugated cardboard box is strengthened, and two sides of the original impression are provided with two reinforcing and fixing ribs, so that an error of two ends of an adhering part of the glued box is obviously lower than the international standard; therefore, requirements on high box gluing speed, high precision, low rejection rate and the like are met, and mechanical or manual correction is not needed any more.

Description

technical field [0001] The invention relates to a packaging machine, in particular to an indentation device of a fully automatic corrugated box folder gluer. Background technique [0002] Regarding the box-gluing method of corrugated cardboard boxes, usually the pre-creasing of the folded edges is carried out by punching the plate first, and then the box is glued on a special machine. Due to the particularity of the corrugated board material, the single-line indentation of the traditional punching knife cannot make the corrugated cardboard box achieve accurate positioning when folding, resulting in the glued part after the box is pasted. The two ends are often not aligned, so the cartons after pasting need to be corrected manually or by machine, but the effect of machine correction is not very obvious. Therefore, corrugated cardboard box folder gluers that meet the high precision requirements on the market now, Most of them are carried out by manual correction, with low aut...

[0002] Regarding the box-gluing method of corrugated cardboard boxes, it is usually to pre-crease the folded edges through plate punching first, and then glue the box on a special machine. Due to the particularity of the corrugated board material, the single-line indentation of the traditional punching knife cannot make the corrugated cardboard box achieve accurate positioning when folding, resulting in the glued part after the box is pasted. The two ends are often not aligned, so the cartons after pasting need to be corrected manually or by machine, but the effect of machine correction is not very obvious. Therefore, the corrugated cardboard box folder gluer that meets the high precision requirements on the market now, Most of them are carried out by manual correction, with low automation procedures, large number of staff and high labor intensity
