[0002] The cutting mechanism in cardboard box production is an indispensable part of the cardboard box manufacturing process. It is responsible for cutting the cardboard into the required size and shape to meet the design requirements of different cardboard boxes.
[0003] There are many types of cutting mechanisms for cardboard box production, each with its own characteristics. Companies can choose the appropriate cutting mechanism based on their production needs and budget. When selecting a cutting mechanism, factors such as cutting accuracy, cutting speed, cutting width adjustment range, fixing method, dust extraction function, and degree of automation should be considered to ensure production efficiency and product quality.
[0004] Cardboard boxes may shift during transport, leading to reduced cutting accuracy. Most existing cardboard box cutting mechanisms do not have automatic centering mechanisms. Once a cardboard box shifts, the machine must be stopped and other tools used to correct it, reducing cutting efficiency and the practicality of the equipment. Utility Model Content

[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the cardboard to be cut is conveyed to the cutting mechanism via a conveyor belt for cutting. During the conveying process, the hydraulic cylinder is activated to push the push block through the connecting rod to make the two L-shaped plates move relative to each other, which in turn drives the two push plates to push the two centering plates to move relative to each other. This ensures that the cardboard is always kept in the center position of the conveyor belt during the conveying process, achieving the effect of automatically centering the cardboard during conveying through the centering mechanism, thereby improving the cutting progress of the cardboard and increasing the work efficiency.
[0023] 2. In this utility model, a large amount of debris is generated during the cutting of cardboard. The vacuum pump is started to extract the air in the collection box to form a negative pressure. At this time, the debris will be sucked into the inside of the collection box through the suction head and suction pipe. After the cutting operation is completed, the debris inside can be taken out by opening the collection box with the handle. This achieves the effect of collecting the debris generated during the cardboard cutting process through the collection mechanism, ensuring the cleanliness and hygiene of the working environment and improving the practicality of the device.
