Film pressing mechanism and film pressing method of profile film sticking machine

Abstract

The invention provides a film pressing mechanism and film pressing method of a profile film sticking machine. The film pressing mechanism of the profile film sticking machine comprises a supporting assembly, an adjusting frame, a jacking assembly and an edge folding assembly, wherein the supporting assembly is used for supporting a profile, and the profile comprises a bottom wall, a first side wall and a second side wall; the adjusting frame is used for adjusting the height of the jacking assembly or the inclination angle of the edge folding assembly, and is in a semi-circular ring shape and provided with an arc-shaped hole; the jacking assembly comprises a first supporting rod installed on the adjusting frame and a first rolling wheel installed at the lower end of the first supporting rod, and the first rolling wheel is in rolling friction with the top of the first side wall of the profile; and the edge folding assembly is located at the downstream of a bottom film unwinding barrel, and comprises a second supporting rod and a second rolling wheel installed at the lower end of the second supporting rod, the upper end of the second supporting rod is fastened into the arc-shaped hole, the second rolling wheel can be in rolling friction with a connecting edge of the bottom wall and the second side wall, and the right side of the bottom film is turned over obliquely upwards to forma pre-folded edge. According to the invention, the problems that a profile film sticking machine is low in film sticking efficiency, and bubbles and wrinkles exist during film sticking can be solved.

Description

technical field [0001] The invention belongs to the technical field of profile film sticking equipment, and in particular relates to a film pressing mechanism of a profile film sticking machine and a film pressing method thereof. Background technique [0002] Metal profiles such as aluminum profiles are commonly used industrial materials, and aluminum profiles are often used in construction industries such as aluminum alloy doors and windows, building curtain walls, etc. Aluminum profiles have excellent machinability, but their surfaces are easily scratched during forming, cutting, drilling, assembly, etc., while doors, windows, curtain walls and other components require aluminum profiles to have smooth, flat, and scratch-free surfaces, so It is necessary to cover the surface of the profile to protect its appearance quality from being affected. [0003] The profile film laminating machine is a commonly used film laminating equipment, which sticks the film material on the su...
