Description

Technical Field

[0001] This utility model relates to the field of tape reel technology, specifically a reflective film reel. Background Technology

[0002] Reflective film is a pre-made thin film that can be directly applied as a retroreflective material. It is made using glass bead technology, microprism technology, synthetic resin technology, thin film technology, coating technology, and micro-replication technology. Solar gap reflective film is a film strip product with directional light reflection effect. It is mainly used in the gaps between the cells on the back panel of double-sided glass modules. Solar gap reflective film is divided into two types: metal gap reflective film and non-metal gap reflective film.

[0003] During the production of reflective film, rolls are used to wind and rewind the finished reflective film for convenient packaging and transportation. Currently, rolls are usually straight-plug type spools without buckles. During use, the chuck and core are prone to loosening, causing the film and thread tape on both sides to fall off, affecting the normal production and use of reflective film and causing huge losses to the finished product. Utility Model Content

[0004] The purpose of this invention is to provide a reflective film roll to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A reflective film roll includes a roll body, the roll body including a chuck and a core, the core being a cylindrical structure, with connecting grooves on both sides of the core, and a retaining groove on the inner wall of the connecting groove, a mounting block being provided on the side of the chuck near the core, the mounting block being inserted into the connecting groove, the chuck being connected to the core through the mounting block, chucks being installed on both sides of the core, and multiple buckles being provided on the outer wall of the mounting block, the buckles being inserted into the retaining groove.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0008] In one alternative: multiple buckles are evenly distributed on the outside of the mounting block, and the mounting block has multiple grooves.

[0009] In one alternative: the chuck is provided with a reinforcing rib on the side away from the core.

[0010] In one alternative: an arc-shaped reinforcing plate is provided between the reinforcing ribs.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The reflective film roll consists of a core and a chuck, and is suitable for winding solar gap reflective film and various ribbon products. The chuck is installed on the side wall of the core, and the mounting block on the chuck is inserted into the connecting groove. Multiple buckles are inserted into the groove and locked in place, realizing the docking and assembly of the chuck and the core. The installation of the sleeve body is more convenient. The chuck and the core are always in a tight fit, preventing the reflective film roll from loosening during use. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. In the drawings and description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.

[0019] In one embodiment, such as Figure 1-4 As shown, a reflective film roll includes a roll body 1, which includes a chuck 2 and a core 3. The core 3 has a cylindrical structure, and connecting grooves 7 are provided on both sides of the core 3. The inner wall of the connecting grooves 7 has a slot 8. A mounting block 4 is provided on the side of the chuck 2 near the core 3. The mounting block 4 has a cylindrical structure and fits into the connecting groove 7. The mounting block 4 passes through the connecting groove 7. The chuck 2 is connected to the core 3 through the mounting block 4. The core 3 has chucks 2 installed on both sides. The outer wall of the mounting block 4 is provided with multiple buckles 5, which pass through the slot 8.

[0020] The reflective film roll consists of a core tube 3 and a chuck 2. The chuck 2 is installed on the side wall of the core tube 3. The mounting block 4 on the chuck 2 is inserted into the connecting groove 7. The buckle 5 on the mounting block 4 is inserted into the slot 8 and locked, realizing the docking of the chuck 2 and the core tube 3. The installation of the sleeve body 1 is more convenient.
