Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic packaging box processing, specifically to a plastic packaging box processing sheet punching machine. BACKGROUND

[0002] Plastic packaging boxes are transparent folding boxes, cylinders, top and bottom cover boxes, and other related plastic products made of PVC, PET, PP, PS, and other materials. They can achieve UV offset printing, silk printing, gold stamping, and frosted printing effects. PP packaging boxes are commonly used for packaging beverages, fruit juice, and cans. These materials have good waterproofness, air permeability, and high-temperature resistance, which help maintain the freshness and taste of food. Medical plastic packaging boxes also play an important role in the pharmaceutical industry, used to load and protect medicines from external environmental pollution. The sheet material of plastic packaging boxes usually needs to be precisely punched to form the required shape and size. The sheet punching machine can efficiently and accurately complete this task, ensuring the quality of the finished plastic packaging boxes.

[0003] Traditional plastic packaging box processing sheet punching machines are integrally connected between the lifting mechanism and the punching tool to ensure the stability of the punching tool during the cutting process, such as welding. After long-term use, not only does it reduce the applicability of the punching machine, but also increases maintenance costs. To solve the above problems, some plastic packaging box processing sheet punching machines first have a plug-in port corresponding to the lifting mechanism and the punching tool. When the punching tool is inserted into the lifting mechanism, it is inserted into the plug-in rod along the plug-in port, connecting the lifting mechanism and the punching tool. This not only improves the applicability of the punching machine, but also reduces maintenance costs. However, this method cannot guarantee the stability of the connection and may also reduce product quality. Therefore, a plastic packaging box processing sheet punching machine is proposed. SUMMARY

After the sheet is moved on the processing table and fixed by the pressing roller, the hydraulic rod drives the cutter seat to descend on the top seat, so that the punch cutter cuts the sheet. On the one hand, it can not only ensure the stability of the connection between the cutter seat and the punch cutter, but also avoid the phenomenon of product quality decline caused by loosening of the cutter seat and the punch cutter.

[0011] Preferably, the positions of the upper connecting hole, the lower connecting hole and the connecting hole correspond to each other, and the radius of the connecting hole is greater than the radius of the upper connecting hole and the lower connecting hole. After the connecting column drives the positioning convex edges to descend along the upper connecting hole, the lower connecting hole and the positioning side groove into the inside of the connecting hole, the connecting column can be rotated.

[0012] Preferably, the positions and shapes of the connecting column, the upper connecting hole, the lower connecting hole and the connecting hole correspond to each other, and the shapes and positions of the positioning convex edges and the positioning side groove correspond to each other. The connecting column can move up and down along the upper connecting hole, the lower connecting hole and the connecting hole, and the positioning convex edges can move up and down along the positioning side groove.
