Problems solved by technology

[0004] Therefore, there will always be a problem in the packaging box processed by the existing gluing technology. The narrow edge or slightly folded edge is always not firmly bonded to the adherend, which is often said to be easy to open the glue.

Embodiment 1

[0027] Please combine figure 1 , figure 2 and image 3 ,

[0028] A roller 20 is formed on the roller with several mesh walls and several mesh holes, and the mesh walls are extended along at least two directions to cross to form at least two different mesh holes. When the roller is passing the glue, the roller is in contact with the glue and rotates. The surface of the roller is dipped in a large amount of glue, and the glue is scraped along the peripheral surface of the roller through the scraper so that the glue on the surface of the roller is only left in the mesh. All the glue outside the hole is scraped off; the facial paper 10 rolls along the surface of the roller, and the glue will be transferred from the mesh to the facial paper 10 . By setting different meshes on the roller, a non-continuous non-uniform over-glue will be formed on the face paper 10 .

[0029] Such as figure 2 , the direction of net wall one 20a and net wall two 20b is perpendicular to each othe...

Embodiment 2

[0034] to borrow figure 1 , image 3 , when the opening of the mesh is the same, the depth of the hole is different; in this case, the mesh is also divided into at least two types, deep hole 34 and shallow hole 33, and on the roller surface, it is shown as deep hole area 32 and shallow hole District 31. The depth two D2 of deep hole 34 is greater than the depth one D1 of shallow hole 33, under the same situation of orifice, then the capacity of deep hole 34 is also greater than the capacity of shallow hole 33, that is to say the glue capacity stored in deep hole 34 is greater than Glue volume in shallow hole 33.

[0035] combine Figure 4 , further, two deep hole areas 32 and one shallow hole area 31 are set on the roller surface. Using this roller to glue the face paper 10 will still realize that the glue density of the side surface 12 is greater than the glue density of the middle surface 11.

[0036] In this case, the width of the net wall one 20a can be the same as th...

Abstract

The invention relates to the technical field of packaging box processing machinery, and discloses a roller, a plurality of net walls and a plurality of meshes are formed on the roller, and the net walls extend in at least two directions to form at least two different meshes in a crossed mode. The invention also discloses a method for controlling the local glue amount of packaging box surface paper by using the roller, which comprises the following steps: the roller with a reticulate pattern on the surface is constructed, the plurality of net walls and the plurality of meshes are formed on the roller, and the net walls extend along at least two directions so as to form at least two different meshes in a crossed mode; and the roller is used for dipping glue to conduct gluing on the packaging box surface paper. The effect of realizing different local glue amounts on one piece of surface paper is realized.

Description

technical field [0001] The invention belongs to the technical field of packaging box processing, and in particular relates to a roller and a method for realizing different local glue amounts on the surface paper of a packaging box. Background technique [0002] In the prior art, the face paper of the packaging box mostly adopts two ways of gluing with smooth rollers or gluing with silk screen. [0003] When processing full-open packaging boxes in the prior art, the inner box is usually prepared first, and then the outer paper is glued to the surface of the inner box to form an outer box. When automatic equipment is used to glue the face paper, the existing structure can only achieve uniform gluing on the surface of the face paper, or partial gluing to avoid glue. In a continuous area on the face paper, the amount of glue per unit area is the same. [0004] Therefore, there will always be a problem in the packaging box processed by the existing gluing technology. The narrow...
