Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, in the cutting mechanism of the prior art cardboard cutting machine, the knife seats and the slitting knives of the first slitting knife group and the second slitting knife group in the upper roll shaft are oriented in the same direction, which results in that, even if the two knife seats are close to each other, there is still a distance of one knife seat between the two slitting knives, so the minimum width of the cardboard that can be formed by the cutting mechanism is affected by the thickness of the knife seat, and in actual demand, the cardboard with the minimum size often needs another device capable of cutting the small-size cardboard.

As shown in fig. 2 and 3, in the technical solution of the present invention, at least more than one group of dividing and cutting knife group 3 is provided on the upper roller shaft 1 and the lower roller shaft 2, the dividing and cutting knife group 3 includes a first dividing and cutting knife group 31 and a second dividing and cutting knife group 32, and the dividing and cutting knife 312 on the first dividing and cutting knife group 31 and the dividing and cutting knife 312 on the second dividing and cutting knife group 32 are arranged face to face. Therefore, the minimum cutting rule of the cutting knife 312 in this arrangement is the distance between the edges of two cutting knives 312, that is, the thickness of one cutting knife 312, and in practical equipment, the thickness of one cutting knife 312 is 1cm, so the minimum cutting distance that can be met can be 1cm, no additional equipment is needed to cut small-sized cardboard, and it should be noted that even if the cutting knives 312 on the first cutting knife group 31 and the second cutting knife group 32 are arranged face to face, the edge orientations of the cutting knives are still consistent.

As shown in fig. 4, in the original cutting mechanism, the cutter holder 311 is sleeved on the upper roller shaft 1 and the lower roller shaft 2, so that when a smaller-sized paperboard needs to be cut, the cutting blades 312 need to be arranged face to face, in the original cutting mechanism, the cutter holder 311 sleeved on the upper roller shaft 1 and the lower roller shaft 2 obviously cannot meet the above requirement, if the cutter holder 311 on one side needs to be removed from the upper roller shaft 1 and the lower roller shaft 2 for replacement, and then adjustment is carried out, which is very troublesome, in order to solve the problem, in the technical scheme, the cutter holder 311 is formed by abutting a first cutter holder 313 and a second cutter holder 314 and is connected by a fastener, therefore when one of the cutter groups 3 needs to be changed for replacing the structure of the component cutting blades 312, only by detaching the fastener and adjusting the orientations of the cutter holder 311 and the cutting blades 312, and then the two tool holders 311 are butted by the fastener. The operation is very convenient.

Specifically, first threaded holes 315 are formed in the first tool holder 313 and the second tool holder 314, and fasteners are used to connect the first tool holder 313 and the second tool holder 314 to each other and fix the first tool holder 313 and the second tool holder 314 to the upper roller shaft 1 and the lower roller shaft 2 by connecting the two first threaded holes 315. And one of the first threaded holes 315 in the first insert seat 313 and the second insert seat 314 is a countersunk hole.

As shown in fig. 5, the cutting blade 312 is also formed by abutting a first cutting blade 317 and a second cutting blade 318 fixed on the first tool seat 313 and the second tool seat 314, and a second threaded hole 316 is formed on each of the first tool seat 313, the second tool seat 314, the first cutting blade 317 and the second cutting blade 318, wherein the second threaded holes 316 on the first cutting blade 317 and the second cutting blade 318 are countersunk holes, which also fix the first cutting blade 317 and the second cutting blade 318 on the first tool seat 313 and the second tool seat 314 respectively by fasteners.

Specifically, the fastener is a hexagon socket head cap screw, and the fastener is not shown in the drawings in the specification, but is easy to understand by those skilled in the art, so that the details are not described again.

As shown in fig. 6, a gap 319 exists between the abutting surfaces of the first slitting knife 317 and the second slitting knife 318, the distance is about 0.1-1mm, and the slitting knife 312 is formed by abutting the first slitting knife 317 and the second slitting knife 318, and is not an integral body, so that deviation is inevitably generated after assembly, gradient difference exists between the two abutting knife edges, the gradient difference can cause the slitting knife 312 to be engaged when slitting the paperboard, and the slitting quality of the paperboard is deteriorated, therefore, a gap is arranged between the abutting surfaces of the first slitting knife 317 and the second slitting knife 318, the gradient difference between the two knife edges can be reduced, and the engagement can be avoided.

the above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
