Description

Technical Field

[0001] The present application relates to the field of mechanical automation technology, and in particular to a punching and shearing mechanism of a plastic cup forming and filling machine. Background Art

[0002] Filling machines are mainly a small category of packaging machines. From the perspective of material packaging, they can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines; from the perspective of the degree of production automation, they can be divided into semi-automatic filling machines and fully automatic filling production lines. After the forming and filling are completed, the food packaging containers need to be sealed, packaged, punched and sheared.

[0003] Patent No. CN208559788U discloses a forming, filling, punching and shearing machine, which performs packaging, punching and shearing on food packaging containers. The conveying component ensures that the food packaging containers are stably transported to each station to avoid errors during sealing. This design improves the accuracy and automation of the equipment, thereby reducing the manpower and material resources of the manufacturer and improving the production efficiency and product quality of the equipment. However, the punching and shearing machine does not fix the food packaging container when punching and shearing it. During the punching and shearing process, the impact force generated by the punching and shearing machine is likely to cause the container to deform, and may damage the food inside the container, increasing the breakage rate and increasing production costs.
