Description

Technical Field

[0001] The utility model relates to the technical field of packaging box processing, in particular to a cutting device for packaging box processing. Background Art

[0002] As an indispensable part of modern logistics, packaging cartons bear the important responsibilities of containing, protecting products and being beautiful. The physical performance indicators of packaging cartons become the basis for their quality evaluation. The production of cartons is to die-cut the cardboard into the unfolded shape of the carton, then press the corresponding indentation at the bending position of the cardboard, and finally fold the cardboard into a carton through the indentation. In the existing carton production process, the carton generally needs to be trimmed during the production process.

[0003] According to the announcement number: CN220262144U, a cardboard trimming device for processing corrugated paper packaging boxes is disclosed, including a base, the top wall of the base is fixedly connected to a left-right symmetrical fixing block, the inside of the left-right symmetrical fixing block is fixedly connected to a first fixing plate that is symmetrical up and down, the opposite side of the first fixing plate that is symmetrical up and down is fixedly connected to one end of a first spring, and the other end of the first spring is fixedly connected to a second fixing plate. In the utility model, the effect of fixing the cardboard is achieved through the cooperation between the fixing block, the first fixing plate, the first spring, the second fixing plate, the support frame, the roller, the third fixing plate, the second spring and the clamping plate.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, although it can solve the problem that some of the current cutting devices manually press the cardboard during the process of trimming the cardboard, the cardboard will move after being subjected to a certain pressure because it is not fully restricted, resulting in the failure of the cardboard trimming and the waste of the cardboard trimming. In addition, when cutting, the cutting knife of some equipment needs to be reset before cutting can be carried out again, which greatly affects the work efficiency.

[0005] In actual use, the above-mentioned device clamps the workpiece using the elastic force generated by two springs. However, since there is a certain limited space between the two springs, in order to avoid too many workpieces being placed in, which would cause excessive spring pressure and damage the workpiece, the device can only clamp and fix a single workpiece, thereby reducing work efficiency and having certain limitations. Utility Model Content

[0006] In order to solve the problems raised in the above-mentioned background technology, the purpose of the utility model is to provide a cutting device for processing packaging boxes, which has the advantage of fixing multiple workpieces and solves the problem that due to the limited space between the two springs, in order to avoid too many workpieces being placed in, resulting in excessive spring pressure and crushing the workpieces, the device can only clamp and fix a single workpiece, thereby reducing work efficiency and having certain limitations.

The limit block is internally slidably connected to a limit rod, and the bottom of the limit rod is fixedly connected to the base.

[0010] As a preferred embodiment of the utility model, the rotating support assembly includes a bearing, the bearing is movably connected to the bottom of the screw rod surface, a mounting hole is opened on the left side of the top of the base, and the bearing is clamped and installed inside the mounting hole.

[0011] As a preferred embodiment of the present invention, a positioning plate is fixedly connected to the right side of the base.

[0012] As a preferred embodiment of the present invention, a protective pad is attached to the bottom of the gravity plate, and the material of the protective pad is natural rubber.

[0013] As a preferred embodiment of the utility model, a rotating wheel handle is fixedly connected to the top of the screw rod, and the rotating wheel handle is used for using the screw rod.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model provides a gravity plate, a clamping mechanism and a limit assembly. When multiple workpieces need to be processed, the operator places the multiple workpieces on the top of the base, and then the clamping mechanism drives the gravity plate to move, so that the gravity plate clamps and fixes the multiple workpieces, so that the operator can process multiple workpieces, which improves the cutting efficiency. It solves the problem that there is a certain limited space between the two springs, in order to avoid too many workpieces being placed, resulting in excessive spring pressure and crushing of the workpieces, which leads to the device being able to clamp and fix only a single workpiece, thereby reducing work efficiency and having certain limitations, and achieves the effect of fixing multiple workpieces.

[0016] 2. The utility model sets a clamping mechanism. When the operator needs to fix the workpiece by the gravity plate, the gravity plate is located on the top of the workpiece, so that the operator turns the screw to rotate, and then the rotating screw drives the moving block to move, so that the moving block drives the gravity plate to descend, so that the gravity plate contacts the workpiece, and the operator continuously rotates the screw to make the gravity plate continuously apply pressure to the workpiece, so that the gravity plate presses and fixes the workpiece, thereby ensuring the stability of workpiece cutting.

[0017] 3. The utility model sets a limit assembly. When the rotating screw drives the gravity plate to move through the moving block, the gravity plate drives the limit block to slide on the surface of the limit rod, so that the limit block and the limit rod limit the movement of the moving block through the gravity plate, thereby preventing the moving block from rotating when the screw rotates.
