Description

Technical Field

[0001] The utility model relates to the technical field of film application, in particular to a protective film attaching device. Background Art

[0002] As people's requirements for the use of electronic products are getting higher and higher, and the screen is the most vulnerable part. Applying a film can effectively reduce the damage to the screen caused by factors such as scratching and dropping, and can also reduce fingerprints left when fingers touch the screen and dust and oil stains accumulated during daily use, thus protecting the screen.

[0003] The existing patent No. CN220701459U discloses a protective film attaching device, aiming to solve the technical problem that the protective film is easily damaged when the current roller is in hard contact with the protective film. It includes a placement structure, a connection structure, a propulsion structure and an extrusion structure; the placement structure; two groups of connection structures are symmetrically arranged on the placement structure; the propulsion structure is slidably arranged on the two groups of connection structures; the extrusion structure is rotatably arranged in the propulsion structure; the extrusion structure includes a round roller and a silica gel sleeve; the round roller is rotatably arranged at the rotating part of the propulsion structure; the silica gel sleeve is sleeved on the round roller; a number of elastic components are arranged between the inner wall of the silica gel sleeve and the outer wall of the round roller, and the silica gel sleeve is elastically connected to the round roller. The utility model has the advantages of making soft contact with the protective film placed on the electronic product screen, and making the outer wall of the silica gel sleeve closely adhere to and extrude the protective film through the directional force generated by the contraction of the elastic components after being extruded, so that the protective film adheres more closely to the electronic product screen.

[0004] In the prior art, when the silica gel sleeve closely adheres to and extrudes the protective film, due to the soft nature of the silica gel sleeve, the air bubbles in the protective film will push up the silica gel sleeve under the action of the elastic components and stay between the protective film and the screen, resulting in a reduction in the attachment effect of the protective film.
