[0001] The utility model relates to a film applying tool, in particular to a film applying tool suitable for assisting in applying films such as protective films or decorative films to the surface of an object to be applied, such as the edge of a vehicle body, such as a door frame. Background Art

[0002] In recent years, with the development of the automotive industry, the requirements for vehicle design and appearance have become increasingly stringent. For example, the application of decorative films such as black film to various parts of the vehicle has become one of the main ways to enhance the appearance of vehicles due to its advantages such as low cost, good environmental performance, convenient application operation and high production efficiency.

[0003] Currently, the application of applying decorative films such as black films to car doors is already very mature. However, the frames of car doors usually have different heights (also known as widths). There is still a lack of suitable tools for applying decorative films to the frames of car doors. If manual operation is somewhat difficult and positioning is inaccurate, bubbles and wrinkles are easily generated when applying the film, resulting in quality defects.

[0004] In addition to the automotive industry, other industries also use decorative films to modify the surface of objects. For the border part of the object surface, especially the parts with different heights or widths, matching film application tools are also required to improve the efficiency and quality of film application.

[0005] Therefore, there is an urgent need for a film applying tool that can be used for film application operations on frame parts of objects with different heights or widths, such as decorative film application on vehicle door frames, to improve film application efficiency and quality and meet the needs of performing effective film application operations.

[0015] It should be noted that the following embodiments are exemplary illustrations of the present invention, and features in different embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with specific embodiments.

[0016] like Figure 1 and Figure 2FIG2 is a schematic diagram of a film applying tool 100 according to an embodiment of the present invention. The film applying tool 100 is used to assist in performing a film applying operation, and includes: a substrate 10 , a first roller 20 , a second roller 30 , and a film clamping unit 40 .

[0017] The substrate 10 includes a first surface 11 (the reverse side, which faces the surface of the object to be coated when in use) and a second surface 12 (the front side, which faces the operator when in use), a first end 13 and an opposite second end 14, a first side 15 and an opposite second side 16, and a guide groove 17 extending through the first and second surfaces 11 and 12 of the substrate 10. The guide groove 17 is located near the second end 14 of the substrate 10 and extends a certain length in the direction facing the first roller 20.

[0018] The first roller 20 is fixed on the first surface 11 of the substrate 10. In this embodiment, there are two first rollers 20 fixed side by side at the first end 13 of the first surface 11. Two or more first rollers 20 help the film application tool 100 to have better balance when moving on the surface of the object to be filmed.

[0019] The second roller 30 is configured to protrude from the first surface 11 of the substrate 10 and to be movable along the guide groove 17. Thus, the distance between the first roller 20 and the second roller 30 can be adjusted by moving the second roller 30 within the guide groove 17, thereby adapting to surfaces of objects to be film-applied having different heights or widths. Therefore, the film applicator 100 is particularly suitable for film-applying operations on objects with borders of different heights or widths.

[0020] The film clamping unit 40 is configured to clamp the film 60 to be applied (e.g. Figure 3 ) and separates the functional layer 61 and release layer 62 of the membrane 60. The membrane clamping unit 40 includes a guide roller 41, a foam roller 42, and a membrane separation element 43. The guide roller 41 and the foam roller 42 are arranged in parallel on the first side 15 of the substrate 10. The membrane separation element 43 is arranged on the second surface 12 of the substrate 10 and adjacent to the guide roller 41. The membrane separation element 43 includes a "V"-shaped structure 431. The gap between the top edge of the "V"-shaped structure 431 and the guide roller 41 allows the membrane 60 to pass through.

[0021] The film clamping unit 40 also includes a first support plate 44, a second support plate 45, a buckle 46, and a handle 47. The first support plate 44 is fixed to the second end 14 of the first side 15 of the substrate 10. The guide roller 41 and the foam roller 42 are fixed to the first support plate 44 and the second support plate 45 at their ends, respectively. That is, the guide roller 41 and the foam roller 42 are fixed between the first support plate 44 and the second support plate 45. The handle 46 is fixed to the second support plate 45, optionally to the surface of the second support plate 45 facing away from the guide roller 41 and the foam roller 42. The buckle 46 is disposed at the first end 13 of the first side 15 of the substrate 10, and the handle 47 can be snapped into the buckle 46. Optionally, the buckle 46 can be a barbed structure, and the handle 47 can be a rod-shaped structure that can be embedded in the barbed structure. Thus, when the handle 47 is not engaged with the buckle 46, the handle 47 can drive the second support plate 45, the guide roller 41, and the foam roller 42 to rotate within a certain range around the first support plate 44, thereby providing more space for mounting and clamping the film to be applied on the film clamping unit 40. The buckle 46 can be fixed to the first side surface 15 of the substrate 10 via a plate-like structure 48, which can be rotatably fixed to the first side surface 15 of the substrate 10 at a certain angle. For example, the plate-like structure 48 is fixed to the first side surface 15 of the substrate 10 via a rotating screw. Thus, rotating the plate-like structure 48 drives the buckle 46 to rotate, thereby separating or engaging the handle 47.

[0022] The film application tool 100 further includes a second roller drive unit 50, which includes a first baffle 51, a second baffle 52, a bracket 53, and a guide rod 54, wherein the first baffle 51 and the second baffle 52 are respectively fixed on the second surface 12 of the substrate 10 and are separated by a certain distance, such as Figure 1 For example, the first baffle 51 is located near the first end 13 of the substrate 10, and the second baffle 52 is located near the second end 14 of the substrate 10. The ends of the guide rod 54 are respectively fixed to the first baffle 51 and the second baffle 52, and the bracket 53 is movably disposed on the guide rod 54. Optionally, the bracket 53 is provided with a through hole 55, through which the guide rod 54 passes. In the embodiment shown in the figure, the second roller drive unit 50 is provided with a guide rod 54.

[0023] The bracket 53 includes a first protrusion 55 and a second protrusion 56, which are respectively disposed on opposite surfaces of the bracket 53. Optionally, the first protrusion 55 is cylindrical and extends through the guide groove 17 to the first surface 11 of the base plate 10. The second roller 30 is fixed to the first protrusion 55. The second protrusion 56 is sheet-like or has other shapes to facilitate the operator to manually move the bracket 53 back and forth along the guide groove 17, thereby driving the movement of the second roller 30.

[0024] The second roller drive unit 50 further includes at least one spring 57, the ends of which are respectively fixed to the first baffle 51 and the bracket 53. When the film applicator 100 is in use, the first roller 20 and the second roller 30 are engaged with the frame of the surface of the object to be applied with the film. The contraction force generated by the extension of the spring 57 helps to securely engage the first roller 20 and the second roller 30 with the frame.

[0025] The bracket 53 further includes a limiting floating block 531, which protrudes from the first side surface 15 of the substrate 10. Optionally, the limiting floating block 531 includes a protrusion that extends between the guide roller 41 and the foam roller 42. In this way, the limiting floating block 531 can confine the film to be applied between the second support plate 45 and the limiting floating block 531.

[0026] Figure 3 and Figure 4 This is a schematic diagram of the film applicator 100 according to one embodiment of the present invention operating while clamping a film. As shown, rotating the plate-like structure 48 drives the buckle 46 to rotate, separating the handle 47. The film clamping unit 40 is then rotated to a position appropriately away from the first side 15 of the substrate 10, and the film 60 is then passed through the gap between the guide roller 41 and the foam roller 42. The film clamping unit 40 is then rotated to a position close to the first side 15 of the substrate 10, and the release layer 62 of the film 60 is extended from the surface of the membrane separation element 43. The functional layer 61 of the film 60 is then passed through the gap between the top edge of the "V"-shaped structure 431 of the membrane separation element 43 and the guide roller 41, and then through the gap between the foam roller 42 and the surface of the object to be applied. Finally, rotating the plate-like structure 48 drives the buckle 46 to rotate, engaging the handle 47.

[0027] like Figure 5 The diagram shows a film applicator 100 in use. The first roller 20 and the second roller 30 of the film applicator 100 are positioned against the frame of the surface 71 of the object 70 to be applied. An operator can hold the film applicator 100 and move the first roller 20 and the second roller 30 along the surface 71 of the object 70 to be applied, thereby applying the film to the surface. Simultaneously, due to the thrust of the frame of the object 70 and the contraction of the spring 57, the second roller 30 automatically moves the bracket 53 back and forth along the guide groove 17, thereby driving the second roller 30 to move away from or toward the first roller 20. This adjusts the spacing between the first roller 20 and the second roller 30 to accommodate the different heights and widths of the surface 71 of the object 70 to be applied, and securely engages the first roller 20 and the second roller 30 with the frame.
