Description

Technical Field

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

[0002] Protective film is a thin film material widely used to protect the surface of various products. It is used to protect the surface of objects from scratches, wear, pollution and chemical erosion during transportation, storage, processing or use. Protective film is used in many fields such as electronic products, automobiles, architectural glass, furniture, flooring, etc. It can not only protect objects from physical damage, but also prevent chemical erosion and ultraviolet aging.

[0003] Currently, when attaching a protective film, it is necessary to first apply glue to the surface of the protected object, and then evenly scrape the glue little by little to make the protective film adhere better to the protected object. However, this method of applying glue is time-consuming and labor-intensive, and it is more troublesome to apply it to the surface of the protected object with a curved or irregular surface. Therefore, in this case, a protective film attaching auxiliary device is needed to help the operator attach the protective film. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a protective film attaching auxiliary device, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a protective film attachment auxiliary device, including a glue tube, the two sides of the glue tube are rotatably provided with connecting parts through a rotating shaft, the inside of the glue tube is plugged with an extrusion rod, the bottom of the connecting part is provided with a long strip, the bottom of the long strip is elastically connected to a soft scraper through a spring, one end of the glue tube is provided with a glue discharge head, the surface of the glue discharge head is connected to a plurality of connecting tubes through a connecting head, a glue coating channel is opened inside the soft scraper, and one end of the connecting tube is connected to the glue coating channel.

[0006] Optionally, the surface of the glue tube is provided with scales for precise glue application.

[0007] Optionally, a fixing bolt is threadedly connected to the surface of the connecting piece, and a fixing hole is opened on the surface of the rotating shaft.

[0008] Optionally, the fixing bolt passes through the connecting member and is threadedly connected to the fixing hole.

[0009] Optionally, a glue outlet slit for expanding the glue outlet area is provided at the bottom of the glue coating channel.

[0010] The utility model provides a protective film attachment auxiliary device, which has the following beneficial effects:

[0011] 1. The protective film attaching auxiliary device can adjust the orientation angle of the soft scraper through the setting of the connecting piece and the rotating shaft, so as to flexibly use the device. Through the coordinated setting of the glue tube, the extrusion rod, the connecting head, the soft scraper and the gluing channel, the operator can directly squeeze and add glue when applying glue, without having to take glue for adding separately, which saves time and effort and greatly facilitates the operator. Through the setting of the spring and the soft scraper, the device can be fitted to the protective objects of different shapes and the glue can be fully and evenly spread to ensure the effect of attaching the protective film in the later stage.

[0012] 2. The protective film attaching auxiliary device, through the setting of the glue discharge head and multiple connecting tubes combined with the glue discharge slit, can evenly add the glue at the extrusion point to the surface of the soft scraper to apply the glue. By setting the fixing bolt and the fixing hole on the shaft, the rotation angle of the shaft is fixed to ensure the fixation of the soft scraper's direction. BRIEF DESCRIPTION OF THE DRAWINGS
