Description

Technical Field

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

[0002] Traditional die cutting refers to a cutting process for post-processing of printed products. The die cutting process can cut printed products or other paper products into die cutting plates according to pre-designed graphics, so that the shape of the printed products is no longer limited to straight edges and right angles. In traditional die cutting production, die cutting knives are combined into a die cutting plate according to the patterns required by product design. Under the action of pressure, the printed products or other sheet blanks are rolled and cut into the required shapes or cut marks. The indentation process is to use an indentation knife or an indentation die to press out line marks on the sheet material under the action of pressure, or use a rolling line wheel to roll out line marks on the sheet material, so that the sheet material can be bent and formed at a predetermined position. Usually, the die cutting and indentation process is to combine the die cutting knife and the indentation knife in the same template and perform die cutting and indentation processing on a die cutting machine at the same time, which is simply called die pressing.

[0003] When this die cutting device processes packaging boxes, die cutting knives are used to die cut the to-be-processed coils, cardboard, etc. When processing packaging boxes of different shapes and sizes, different die cutting knives are required. Generally, the die cutting knives and equipment in the machine are fixedly connected. When cutting different packaging boxes, the equipment needs to be replaced, which is rather troublesome. Secondly, when processing packaging boxes, accidents often occur during the cutting of raw materials by die cutting knives. The die cutting knives cut other objects that accidentally enter below the die cutting knives. Finally, when the raw materials are conveyed by the conveyor belt, due to the lack of a fixing device for the raw materials, the raw materials often fall off the conveyor belt. Therefore, a die cutting device for processing packaging boxes is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a die cutting device for processing packaging boxes to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A die-cutting device for processing packaging boxes, including a workbench, a baffle, and a die-cutting knife. Rotating shafts are connected to both ends of the workbench, a conveyor belt is wound around the outer sides of the rotating shafts, fixing plates are fixedly connected to the outer sides of the conveyor belt, fixing rods are fixedly connected to the tops of the fixing plates, a chute is provided at the bottom of the baffle, a C-shaped arched frame is fixedly connected to the top of the workbench, a hydraulic cylinder is fixedly connected to the top of the arched frame, a circular stopper is fixedly connected to the output end of the hydraulic cylinder, a rubber block is fixedly connected to the bottom of the stopper, a threaded tube is rotatably connected to the outer side of the stopper, a screw rod is fixedly connected to the center of the top of the die-cutting knife, a fixing bin is fixedly connected to the bottom of the die-cutting knife near the edge, a receiving bin is provided inside the fixing bin, a spring is fixedly connected to the top inside the receiving bin, a slider is slidably connected inside the receiving bin, a connecting rod is fixedly connected to the bottom of the slider, and a lower stopper is fixedly connected to the bottom of the connecting rod.

[0012] 1. In the present utility model, by setting the stopper, rubber block, threaded tube, and screw rod, a detachable structure can be set between the die-cutting knife and the main equipment. When processing packaging boxes of different models and it is necessary to replace the die-cutting knife, the die-cutting knife can be disassembled by loosening the threaded tube, and a suitable die-cutting knife can be installed under the hydraulic cylinder;

[0013] 2. In the present utility model, by setting the fixing bin, receiving bin, spring, slider, connecting rod, and lower stopper, other objects can be prevented from entering under the die-cutting knife during the processing.
