Problems solved by technology

[0006] 1. After the cutting knife has been processed in large quantities, the blade will be worn, and the worn part will be quickly blunted, and the edge (11a, 11b) of the box opening will be torn off, resulting in burrs and defective products.
[0007] 2. The contact form between the cutter and the carton is sliding and frictional, causing the edge of the box mouth to be torn. When the blade overcomes the resistance of the paper fibers, it will drag and tear the fibers on the edges of the box mouth on both sides, resulting in a joint effect that will tear the edge of the box mouth. (11a, 11b) are destroyed, and defective products will also be obtained

Embodiment 1

[0027] This embodiment provides a solution to make the cutting effect of the box mouth more smooth and beautiful.

[0028] Such as image 3 As shown, the incoming material of the carton 10 is block-shaped, and its thickness faces four different directions. The carton is conveyed on the conveying path 66, and the surface to be cut of the carton is the surface in three directions of the thickness surface, towards the edge of the conveying path 66; a cutter 20 is set on the edge of the conveying path 66, when the carton is along the conveying path 66 when advancing, the cutting knife 20 cuts the paper material to be cut along the roll of the surface to be cut close to it; wherein, the cutting knife 20 can rotate.

[0029] Measure the size of the box type in advance, adjust the width of the conveying path 66, make the carton 10 keep walking in a straight line on the conveying path, and adjust the degree of slight extrusion between the blade of the cutter 20 and a cut surface of t...

Embodiment 2

[0034] This embodiment provides a solution to make the cutting effect of the box mouth more smooth and beautiful, and also has the convenience of automatic processing.

[0035] Such as Figure 4 , the conveying path 66 is configured as at least two, one conveying path 66a is provided with cutters on both side edges, and the other conveying path 66b is provided with a cutter on one side edge, and the two conveying paths are perpendicular to each other. The carton can pass through the conveying path 66a first, so that its two faces to be cut are cut on this conveying path 66a, and at the end of this path, keep its posture unchanged, and then be cut on another conveying path 66b for the second time. Three sides to be cut.

[0036] The form of pushing the carton on the conveying path can have many forms, such as two vertically arranged chain plates or two pushing block structures to continue pushing the box to change its walking direction.

Embodiment 3

[0038] This embodiment provides a solution to make the cutting effect of the box mouth more smooth and beautiful, and also provides a cutting knife assembly with high straightness and low cost.

[0039] Figure 5 It is the first embodiment of the cutter assembly, which has the cheapest cost and is the easiest to assemble and disassemble. The cutter assembly includes a cutter 20, a connecting shaft 21, a bearing 22, a bushing 23 and a mounting seat 24. The connecting shaft 21 is radially provided with a boss, and the cutter 20 is set on the connecting shaft and is stuck on one side by the boss. One side is supported by the inner ring 22a of the bearing 22, and the connecting shaft 21 is tightened from the upper end to realize the fixed connection between the connecting shaft 21, the cutter 20 and the inner ring 22a of the bearing, and the bushing 23 connects the outer ring 22b of the bearing 22 to the mounting seat 24 fixed directly or indirectly. When the carton is in contac...

Abstract

The invention belongs to the technical field of packaging box processing, and discloses a paper box opening cutting process. A paper box is conveyed on a conveying path, and a to-be-cut surface of the paper box faces the edge of the conveying path; a cutter is arranged on the edge of the conveying path, and when the paper box advances along the conveying path, the cutter cuts the to-be-cut surface along the to-be-cut surface in a rolling mode; and the cutter can rotate. The invention discloses a box opening device which adopts the paper box opening cutting process. According to the technical scheme, the cutting effect of the box opening can be improved, and the box opening is smoother and more attractive.

Description

technical field [0001] The invention belongs to the technical field of packaging box processing, and in particular relates to a cutting process for a carton opening and a box opening device using the process. Background technique [0002] Full-open packaging boxes are widely used in cigarette packs, and the gradually mature technology has simultaneously improved the processing quality and processing efficiency of full-open packaging boxes. [0003] The method of making of existing full-open packing box is as figure 1 As shown: first prepare the outer box, that is, the carton block 10 in which the outer paper fully covers the inner box, and then use the carton opener to trim the three sides of the carton block and take out the inner mold. Among them, the inner mold is collected and recycled, and the opened cartons are then sorted and sorted. Under this technology path, the three-sided edge trimming process is now integrated into a box opening machine to realize, and the cut...
