Description

Technical Field

[0001] This utility model relates to the field of film covering technology, specifically a film covering device with a limiting structure. Background Technology

[0002] During the agricultural planting stage, it is usually necessary to build small arched sheds or lay plastic film for insulation. In traditional methods, building agricultural arched sheds requires entirely manual labor for covering the film. This usually requires three people: two to support the two ends of the plastic film, and a third to pull the film to cover it. Laying the film requires two people: one to stretch the plastic film, and the other to control the film covering device and cut the film short.

[0003] A simple film covering device (CN201720920176.8) can be completed by one person, eliminating the need for moving around to adjust the film's condition and cut it. This greatly simplifies the workload of film covering and improves the efficiency of film laying. Its simple structure facilitates widespread application. However, it has shortcomings. During film transport and covering, the film is prone to width deviation and longitudinal movement due to uneven traction speed and unbalanced force, resulting in wrinkles and misalignment, severely affecting the covering quality. Furthermore, it is difficult to adapt to different widths. Therefore, a film covering device with a limiting structure is needed to solve these problems. Utility Model Content
