Technical Field

[0001] The invention relates to a high-precision film wrapping machine, belonging to the field of cargo packaging equipment. Background Art

[0002] In industrial production, film laminating equipment is one of the essential equipment for product packaging. Film wrapping machines can be used to wrap the film on the outside of products or their packaging boxes to prevent damage to the products caused by moisture or damage to the products during transportation. The traditional film laminating method is to wrap the products with film manually, but this method has high labor costs and labor intensity, and low film laminating efficiency.

[0003] At present, most of the box goods on the market are wrapped by film wrapping balers. However, during the packaging process, film wrapping balers usually wrap the box around with film, and the wrapping process relies on manual adjustment, which can easily cause uneven packaging, material waste and inconsistent packaging strength. In addition, the film has basically no protective effect on the box, and an additional protective layer is required during transportation. Summary of the invention
