Description

Technical Field

[0001] This utility model specifically relates to the field of film coating technology, and more specifically to a film coating device for vehicle body sticker production. Background Technology

[0002] As a material widely used for vehicle exterior decoration, advertising, and protecting the vehicle's paint, the lamination process in the production of vehicle wraps is crucial. In the production of vehicle wraps, lamination is used to improve the weather resistance, abrasion resistance, scratch resistance, and waterproof performance of the wraps, while also enhancing their surface gloss and aesthetics, and extending their service life. Traditional vehicle wrap lamination methods may have some problems, such as low efficiency of manual lamination, difficulty in ensuring uniformity and adhesion, and the tendency to produce defects such as bubbles and wrinkles, affecting the quality and appearance of the vehicle wraps.

[0003] With the rapid development of the automotive industry and the increasing demand in the vehicle wrap market, higher requirements are being placed on the production efficiency and quality of vehicle wraps. Therefore, a specialized laminating device for vehicle wrap production is needed to achieve automated or semi-automated laminating operations, improve laminating efficiency and quality, and reduce errors and defects caused by manual operation to meet the needs of large-scale production. At the same time, the device should also have a certain degree of flexibility to adapt to vehicle wraps of different sizes, shapes and materials, and be able to precisely control parameters such as laminating tension and temperature during the laminating process to ensure stable and reliable laminating effect and quality.

[0004] Traditional vehicle wrapping equipment cannot effectively remove impurities from the surface of the wrap during the wrapping process, which may affect the quality of the wrap. In addition, most current wrapping equipment can only wrap one side of the wrap, which will affect the lifespan of the wrap. Furthermore, traditional wrapping equipment requires manual inspection after wrapping, resulting in low work efficiency. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-10 In this embodiment of the present invention, a film-coating device for vehicle body wrapping production includes a support frame 1; one end of the support frame 1 is provided with a plurality of transmission rollers 2, and one end of each transmission roller 2 is provided with a fixed limiting plate 3; the ends of the plurality of transmission rollers 2 away from the fixed limiting plate 3 are provided with movable limiting plates 4; both ends of the movable limiting plate 4 are movably installed on the upright plate on the support frame 1 through lifting rods 5, and a first spring 6 is sleeved on the lifting rods 5 between the upright plate and the movable limiting plate 4;

[0033] A sorting structure 7 is provided at one end of the upright plate; the sorting structure 7 is fixedly installed on the support frame 1, and multiple sets of cooperating rollers are provided inside the sorting structure 7; a film coating assembly 8 is provided at the end of the sorting structure 7 away from the transmission roller 2; the film coating assembly 8 includes a support frame 80; the bottom of the support frame 80 is fixedly installed on the support frame 1; a crossbeam frame 82 is fixedly installed on the top of the support frame 80; two sets of symmetrical sliding rods 87 are provided on the crossbeam frame 82; an mounting plate 810 is fixedly installed at the bottom of the sliding rod 87, one set of mounting plates 810 is fitted with a squeezing roller 83, and the other set of mounting plates 810 is fitted with a film coating roller 84; by the cooperation between the bottom of the film coating roller 84 and the top of the carrier plate 85, the upper and lower films are fitted onto the car body sticker, thereby achieving the effect of double-sided film coating on the car body sticker;

[0034] By using multiple sets of cooperating rollers in the sorting structure 7, dust and oil stains on the surface of the vehicle body sticker during transmission are effectively cleaned, thereby ensuring the cleanliness of both sides of the vehicle body sticker. This effectively ensures the tightness between both sides of the vehicle body sticker and the film during lamination, thus ensuring the lamination quality of the vehicle body sticker.

[0035] The support frame 80 is provided with a first film feeding roller 81 at the top of one end near the finishing structure 7; a first guide roller 89 is provided between the first film feeding roller 81 and the film coating roller 84; the first guide roller 89 is movably installed on the support frame 80 through a mounting block; the film on the first film feeding roller 81 is transferred to the bottom of the film coating roller 84 through the first guide roller 89, thereby ensuring the fit between the film on the upper part and the vehicle body sticker;

[0036] By adopting the above technical solution, when the vehicle sticker is transported by the transmission roller 2, it is transported along one side of the fixed limiting plate 3. By adjusting the distance between the moving limiting plate 4 and the fixed limiting plate 3, the effect of limiting the transmission of vehicle stickers of different sizes can be effectively met. When the vehicle sticker is transported to the sorting structure 7, multiple sets of cooperating rollers effectively clean impurities or dust on the surface of the vehicle sticker. At the same time, after the vehicle sticker passes through multiple sets of cooperating rollers, the flatness of both sides of the vehicle sticker is effectively guaranteed, thereby effectively improving the quality of the film coating.

[0037] In this embodiment, a second spring 88 is sleeved on the slide rod 87 between the mounting plate 810 and the crossbeam frame 82; the bottoms of the extrusion roller 83 and the laminating roller 84 are in contact with the surface of the carrier plate 85; the second spring 88 effectively presses down on the mounting plate 810, allowing the slide rod 87 to slide up and down along the crossbeam frame 8 for adjustment. Thus, during lamination, when the thickness of the vehicle body sticker changes, the extension and retraction of the second spring 88 effectively adjusts the spacing between the laminating roller 84 and the extrusion roller 83 and the carrier plate 85, thereby meeting the lamination needs of different thicknesses of vehicle body stickers.

[0038] In this embodiment, a slitting groove 817 is provided on the carrier plate 85; the slitting groove 817 is located between the extrusion roller 83 and the coating roller 84; the carrier plate 85 is also provided with a rectangular groove to facilitate the installation of the second guide roller 811, which is located on the side of the coating roller 84 away from the extrusion roller 83.

[0039] The bottom of the carrier plate 85 is provided with a support structure to facilitate the placement of the second film-coating roller 814; the film of the second film-coating roller 814 is transferred to the second guide roller 811 via the third guide roller 819; the film on the second film-coating roller 814 is transferred to the top of the carrier plate 85 via the third guide roller 819 and the second guide roller 811, so that the car body sticker transferred from the sorting structure 7 is located between the upper and lower films, thus effectively achieving the effect of simultaneous film coating on the upper and lower sides of the car body sticker and improving production efficiency;

[0040] By adopting the above technical solution, when the vehicle body sticker is transferred to the film coating assembly 8, the first film coating feeding roller 81 is transferred to the bottom of the film coating roller 84 through the first guide roller 89, and the film on the second film coating feeding roller 814 is transferred to the bottom of the film coating roller 84 through the third guide roller 819 and the second guide roller 811. At this time, the transferred vehicle body sticker is located between the upper and lower films, thereby effectively achieving the double-sided film coating effect of the vehicle body sticker.

[0041] Furthermore, during the lamination process, the laminating roller 84 is installed in conjunction with the slide bar 87 via the mounting plate 810. The slide bar 87 and the second spring 88 can automatically adjust the gap between the bottom of the laminating roller 84 and the carrier plate 85, thereby effectively achieving the lamination effect on car body stickers of different thicknesses.

[0042] In this embodiment, a horizontal plate 86 is also fixedly installed at the bottom of the carrier plate 85; two symmetrical pulleys 815 are installed at both ends of one side of the horizontal plate 86; the two pulleys 815 are connected by a belt 813, and one of the pulleys 815 is fixedly installed to the output shaft of the drive motor 812; the drive motor 812 is fixedly installed at one end of the horizontal plate 86.

[0043] An installation block 818 is fixedly installed on the belt 813; a cutter 816 is fixedly installed inside the installation block 818; the cutter 816 passes through the slitting groove 817;

[0044] By adopting the above technical solution, after the film is applied, the car body sticker and the film are simultaneously transferred to the bottom of the extrusion roller 83. The extrusion roller 83 effectively flattens out any air bubbles or wrinkles generated during the film application process, thereby ensuring the quality of the film application. While the extrusion roller 83 is working, the drive motor 812 drives the belt 813 to rotate through two pulleys 815. During the movement of the belt 813, the cutter 816 moves laterally along the slitting groove 817 opened on the carrier plate 85 through the mounting block 818, thereby effectively cutting the upper and lower films. Finally, the film-applied car body sticker is transferred to the receiving plate 9.

[0045] The working principle of this utility model is as follows: When the vehicle sticker is transported by the transmission roller 2, it is transported along one side of the fixed limiting plate 3. By adjusting the distance between the movable limiting plate 4 and the fixed limiting plate 3, the effect of limiting the transmission of vehicle stickers of different sizes can be effectively met. When the vehicle sticker is transported to the sorting structure 7, multiple sets of cooperating rollers effectively clean impurities or dust on the surface of the vehicle sticker. At the same time, after the vehicle sticker passes through multiple sets of cooperating rollers, the flatness of both sides of the vehicle sticker is effectively guaranteed, thereby effectively improving the quality of the film coating.

[0046] When the vehicle body sticker is transferred to the laminating assembly 8, the first laminating feed roller 81 is transferred to the bottom of the laminating roller 84 through the first guide roller 89, and the film on the second laminating feed roller 814 is transferred to the bottom of the laminating roller 84 through the third guide roller 819 and the second guide roller 811. At this time, the transferred vehicle body sticker is located between the upper and lower films, thereby effectively achieving the double-sided laminating effect of the vehicle body sticker.

[0047] During the lamination process, the laminating roller 84 is installed in conjunction with the slide bar 87 via the mounting plate 810. The distance between the bottom of the laminating roller 84 and the carrier plate 85 can be automatically adjusted by the slide bar 87 and the second spring 88, thereby effectively achieving the lamination effect on car body stickers of different thicknesses.

[0048] After lamination is completed, the vehicle body sticker and the film are simultaneously transferred to the bottom of the extrusion roller 83. The extrusion roller 83 effectively smooths out any air bubbles or wrinkles generated during the lamination process, thereby ensuring the quality of the lamination. While the extrusion roller 83 is working, the drive motor 812 drives the belt 813 to rotate through two pulleys 815. During the movement of the belt 813, the cutter 816 moves laterally along the slitting groove 817 opened on the carrier plate 85 through the mounting block 818, thereby effectively cutting the upper and lower films. Finally, the laminated vehicle body sticker is transferred to the receiving plate 9.
