Description

Technical Field

[0001] This utility model relates to the field of reflective film processing technology, specifically to a dust-adhesive device for rewinding reflective film. Background Technology

[0002] Reflective film is a type of retroreflective material that has been made into a thin film and can be applied directly. It is made using glass bead technology, microprism technology, synthetic resin technology, thin film technology, coating technology, and micro-replication technology.

[0003] Existing patent document CN222607418U discloses a dust-adhesive device for rewinding reflective film, comprising a base plate, a reflective film guiding mechanism mounted on one side of the upper end face of the base plate, a rewinding assembly mounted on the reflective film guiding mechanism, and a pusher frame mounted on the other side of the upper end face of the base plate, on which a dust-adhesive assembly is mounted. The dust-adhesive assembly includes a push plate, with two first electric push rods symmetrically fixed at the top and bottom of one side of the push plate. The two first electric push rods at the top and the two first electric push rods at the bottom of the push plate are connected to clamping rods. The reflective film guiding mechanism includes two L-shaped support plates welded to the top of the base plate. In this invention, through the coordinated use of the reflective film guiding mechanism, the rewinding assembly, the pusher frame, and the dust-adhesive assembly, dust on the reflective film is removed during the rewinding process, effectively preventing dust from being drawn into the reflective film during rewinding, thus ensuring product quality.

[0004] Although the device has many benefits, it still has the following problems: the device cannot quickly adapt to the production needs of reflective film of different thicknesses, and the pushing distance of the electric push rod needs to be adjusted multiple times before use, which seriously affects production efficiency. Secondly, the dust-adhesive component of the device comes into contact with the film surface. When the reflective film experiences tension changes or slight vibrations during high-speed winding, it is very easy for the film surface to be excessively squeezed, which in turn causes quality problems such as product scratches, wrinkles, or stretching deformation.

[0023] It is worth noting that, in order to shrink the sticky roller 3, the shrinking mechanism 100 specifically includes: a plurality of rotating seats 101 rotatably connected to both ends of the sticky roller 3; Multiple damping spring shock absorbers 102 are welded to the outer wall of the rotating seat 101 at one end, and a movable plate 103 is welded to the other end of the multiple damping spring shock absorbers 102, which can shrink the dust roller 3.

Multiple limiting grooves 105 are formed on the outer wall of the rotating seat 101, and the other end of multiple limiting rods 104 are slidably connected to the inner wall of the limiting grooves 105, which can limit the movement direction of the dust roller 3. The rotating rod 106 is welded between multiple rotating seats 101, and the dust-sticking roller 3 is rotatably connected to the outer periphery of the rotating rod 106, allowing the dust-sticking roller 3 to rotate together with the reflective film.
