Laminated surface paper with avoiding belts and manufacturing method of uncovered line-drawing-free open box

Abstract

The invention relates to the technical field of packaging box processing, and discloses laminated surface paper with avoiding belts. The laminated surface paper comprises a surface paper base body, wherein a plurality of indentation lines are prefabricated on the surface paper base body, the multiple indentation lines divide the surface paper base body into various surfaces corresponding to a rectangular body, the surface paper base body comprises an upper bottom surface and a lower bottom surface, a rear side surface corresponding to the rectangular body is arranged between the two bottom surfaces, and the outer side edges of the two bottom surfaces are provided with a front side surface, a left side surface and a right side surface corresponding to the rectangular body; a glue layer applied to the surface of the surface paper base body; and the glue avoiding belts arranged on the left side face and the right side face corresponding to the rectangular body and extend in the length direction of the outer side edges. The invention also discloses a manufacturing method of preparing an uncovered line-drawing-free open box by using the laminated surface paper, and the method can solve the line drawing phenomenon of the open box and reduce the reject ratio of the open box on a production line.

Description

technical field [0001] The invention belongs to the technical field of packaging box processing, and in particular relates to a method for making a glued surface paper with an escape belt and an open box with the cover opened and without wire drawing. Background technique [0002] In the existing technology, such as figure 1 The manufacturing method of the open box is roughly divided into three steps. In the first step, the inner mold is used as the support to make the enclosure, and then the sky cover and the ground cover are assembled outside the inner mold enclosure to form the inner box 10. The second step is to use the inner box 10 as the support. The outer paper 20 wraps the outer surface of the inner box to make an outer box. The third step is to cut three faces of the outer box along the seam of the sky cover and the ground cover and take out the inner mold. Of course, in the fully automated process from incoming materials to finished products, it requires the joint...

AI Technical Summary

Problems solved by technology

This kind of product with wire drawing at the closing part does not meet the factory specifications and is judged as a defective product

like figure 2 As shown, there are two reasons: one is due to the natural defects of the box-making method, the sky cover 11 and the ground cover 12 are assembled together separately, so there must be a gap 30 in the sky and the ground cover, and they are attached to the gap. The glue 21 on the glued surface paper will overflow into the gap 30 due to pressure bubbles. When the cover is opened, the glue between the end surface 110 of the sky cover and the end surface 120 of the ground cover will be pulled due to tearing; The glue 21 is not squeezed or overflows into the gap 30. When the opening process is performed, the cutter cuts the outer paper 20. If the local glue amount of the glue 21 at the gap is too large, only the paper layer will be cut off. If the glue layer is not cut off, the drawing phenomenon will still occur when the cover is opened
