Description

Technical Field

[0001] The utility model relates to the technical field of a film pressing mechanism, in particular to a film pressing mechanism for a reflective film. Background Technique

[0002] A reflective film is a retroreflective material that has been made into a film and can be directly applied. It is made by using glass bead technology, microprism technology, synthetic resin technology, film technology, coating technology, and microreplication technology. In the production process of the reflective film, a film pressing mechanism is usually required to press the pattern on the surface of the embossing roller onto the surface of the reflective film.

[0003] As described in a film pressing mechanism for a reflective film (authorization publication number: CN 221272282 U) disclosed by the patent network, "The utility model discloses a film pressing mechanism for a reflective film, which is applied in the field of a film pressing device for a reflective film and includes a base. The top of the base is symmetrically bolted with support plates; by arranging an adjustment groove on the support plate and cooperating with the use of an adjustment seat and a hydraulic cylinder, when it is necessary to adjust the distance between the printing roller and the roller, only need to start the hydraulic cylinder to drive the adjustment seat to move inside the adjustment groove, and the two adjustment seats can drive the height position of the printing roller to be adjusted, achieving the purpose of being applicable to reflective films of different thicknesses and improving its applicability. By threadedly connecting a limit seat on one of the adjustment seats, when the printing roller needs to be replaced with other patterns, only need to unscrew the bolts of the connecting rod and the rotating rod and the connecting rod and the flange on the connecting seat, rotate the limit seat to drive the connecting seat away from the connecting rod, so that there is enough distance for the printing roller to be disassembled, without disassembling the bearing seat on the metal bracket, improving the replacement efficiency."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During the use of this utility model, by starting the hydraulic cylinder, the adjustment seat can drive the printing roller to change its height, which can be applicable to the production of reflective films of different thicknesses.
