[0012] A film covering method of a billboard manufacturing film covering equipment, comprising the following steps:

[0013] Step one, through the stable support of the base, the equipment is powered on, and the controller is controlled and set.

[0014] Step two, the film roll is sleeved on the sleeve shaft of the first shaft support, then one end of the film roll is pulled and passes through the first film tearing assembly and the second film tearing assembly on the left side of the film covering structure between the conveying belt assembly, the second film tearing assembly is above the first film tearing assembly and is clamped downward, and the convex groove is opposite before clamping by controlling the rotation of the roll;

[0015] Step three, when the roll is clamped and the convex groove is opposite, the suction cup is extended into the convex groove and works by the corresponding air pump to generate suction, the second film tearing assembly adsorbs the film, and the first film tearing assembly adsorbs the film paper;

[0018] Step six, after the film is covered, the second film tearing assembly on the front side of the conveying belt assembly is repeatedly controlled to move to the left side of the conveying belt to the left side of the advertisement, at this time, the film is pressed down by the other film covering structure, then the suction cup of the second film tearing assembly moving to the left side is adsorbed to fix the film, then the film cutting structure between the second film tearing assembly and the conveying belt is driven to move forward to cut the film, and the advertisement can be continuously put in to cover the film again according to the above steps.

[0020] 1. Automated operation and increased speed: When existing laminating machines use manual cutting, tearing and feeding, the speed of manual operation is limited and fatigue is easy to occur, which affects the overall laminating efficiency. However, the mechanical structure in this solution, through the cooperation between various components, such as the first film tearing component, the second film tearing component, the conveyor belt component and the film cutting structure, can carry out laminating operations continuously, which greatly improves production efficiency.

[0021] 2. Reduce downtime between processes: In manual operation, there is a transition time between completing one process (such as cutting) and the next process (such as peeling off the film), during which workers need to adjust tools and prepare materials. In automated lamination solutions, the connections between various components are tight. For example, after the film and the backing paper are separated and the backing paper is rolled up, the film with adhesive can be immediately conveyed to the next stage for lamination, with almost no downtime. This makes the entire lamination process smoother and further improves the overall lamination efficiency. Attached Figure Description
