Description

Technical Field

[0001] The utility model relates to the technical field related to reflective films, in particular to a reflective film attaching mechanism. Background Art

[0002] There is a reflective film attaching mechanism (Announcement No.: CN220181196U) which is equipped with a side frame, a winding roller, a compacting member and a limit member. The device rolls up the reflective film on the winding roller. When in use, the reflective film is passed over the bearing shaft and starts to adhere to the reflective film from one end of the compacting member. During the operation, the handle on the compacting member is pressed to allow the compacting shaft to be tightly pressed against the back of the reflective film to avoid the generation of bubbles, etc., and the attaching mechanism is gradually moved during the process so that the attaching mechanism continuously pulls out the reflective film and can attach it along a certain direction, thereby achieving continuous attachment of the reflective film and avoiding positional deviation.

[0003] The above-mentioned existence, although the reflective film can be attached, the size of the pressure roller is fixed, and thus the size of the reflective film that can be attached is limited. When attaching reflective films of different sizes, the use lacks certain flexibility. Utility Model Content

[0024] The cam 8 is a kind of cam which is used to move the rollers 10 and 10 together so that the rollers 10 can move smoothly. The two sets of slide rails 13 are fixed to the main scraper 1, and the two sets of auxiliary scrapers 6 are connected to the main scraper 1 by connecting shafts. The two sets of columns 14 are respectively fitted with the two sets of plate bodies 7. The columns 14 are used to better push the plate body 7 to move away from the main scraper 1 when the auxiliary scraper 6 rotates. The two sets of auxiliary scrapers 6 and the main scraper 1 away from the end of the dual-axis motor 2 are placed in the same plane, so that the auxiliary scraper 6 and the main scraper 1 are The scraper 1 can stably attach the reflective film to the objects transported on the external conveyor belt. Two groups of push rods 12 are installed at the two groups of main scrapers 1. The push rods 12 are used to be installed with the external frame, and then the push rods 12 can drive the auxiliary scraper 6 and the main scraper 1 to move up and down, so that the auxiliary scraper 6 and the main scraper 1 can attach the reflective film to the objects transported on the external conveyor belt.
