Description
Technical Field
[0001] This utility model relates to the field of thin film processing technology, and in particular to an adhesive coating device for automotive film processing. Background Technology
[0002] Automotive films are various thin films used on automobiles, such as color-changing films, car wraps, and window films. Some automotive films require surface adhesive during production, such as multi-layer adhesive composite film structures or film structures that require surface adhesion. For this purpose, a special adhesive application device is needed to apply adhesive to the surface of the automotive film.
[0003] When applying adhesive, it is common practice to spray adhesive onto specific areas and then use an adhesive roller to smooth the adhesive. However, this approach presents two problems. First, when spraying adhesive onto specific areas of the car film surface, the adhesive spots are too concentrated, which can easily lead to uneven application even with the adhesive roller. Second, adhesive residue remains on the surface after continuous application by the adhesive roller, and once the adhesive dries, it will affect the effectiveness of subsequent applications. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an adhesive coating device for automotive film processing, which can expand the diffusion range of the sprayed adhesive, avoid the adhesive being sprayed too concentrated on the surface of the automotive film parts, and improve the uniformity of subsequent adhesive application.
[0005] The technical solution adopted by this utility model is: to provide an adhesive coating device for automotive film processing, including a base, on which a guiding coating component and an adhesive spraying component are provided; The guiding coating assembly includes two first brackets, one on the left and one on the right, fixed to the base respectively; guide rollers are rotatably connected to the first brackets respectively; an adhesive roller is also rotatably connected to the left first bracket; a guide roller is also rotatably connected to the right first bracket; the guide rollers, adhesive rollers, and guide rollers are all horizontally arranged and parallel to each other; the adhesive roller on the left is located above the guide roller on the left, and the gap between them is used to allow the automotive film to pass through; the guide roller on the right is located above the guide roller on the right, and the two are used to clamp the automotive film. The adhesive spraying assembly includes a second bracket fixed on a base; a diverter shell is provided on the upper part of the second bracket; the diverter shell is positioned across the top of the automotive film component; the diverter shell is slidably connected to the second bracket along its length; multiple adhesive spraying nozzles facing the automotive film component are evenly connected below the diverter shell; an adhesive storage tank and an adhesive pump are fixed on the base; the adhesive pump is connected to the adhesive storage tank through an extraction pipe, and to the diverter shell through an outlet pipe; the second bracket is also provided with a driving component for driving the diverter shell to reciprocate along its length on the second bracket.
[0006] To further optimize this technical solution, the two guide rollers of an adhesive coating device for automotive film processing are at the same horizontal height.
[0007] To further optimize this technical solution, a scraper is provided on the upper side of the coating roller of an adhesive coating device for automotive film processing; the length direction of the scraper is parallel to the axial direction of the coating roller; the scraper is connected to the first bracket on the left side through a connecting rod; the lower end of the scraper makes corresponding frictional contact with the surface of the coating roller.
[0008] To further optimize this technical solution, the connecting rod of an adhesive coating device for automotive film processing is detachably connected to the first bracket on the left side via bolt fasteners.
[0009] To further optimize this technical solution, a barrier is connected to the side of the adhesive accumulation on the scraper plate of an adhesive coating device for automotive film processing.
[0010] To further optimize this technical solution, the coating roller of an adhesive coating device for automotive film processing is driven by a first motor connected to the first bracket on the left side.
[0011] To further optimize this technical solution, a driving component of an adhesive coating device for automotive film processing includes a stop fixed on one side of a second bracket and a second motor fixed on the other side of the second bracket; the stop is connected to one end of the flow divider housing along its length via a compression spring; a cam is correspondingly fixed to the output end of the second motor; the cam abuts against the other end of the flow divider housing along its length; when the distal end of the cam abuts against the flow divider housing, the compression spring is in a compressed state.
[0012] The beneficial effects of this utility model are as follows: The left-side coating roller is positioned above the left-side guide roller, with a gap between them to allow the automotive film to pass through. The right-side guide roller is positioned above the right-side guide roller, and both are used to clamp the automotive film. This design achieves a guiding effect during the transfer of the automotive film, ensuring that the coating area of the automotive film is stretched and flat, and guaranteeing accurate alignment between the coating area and the adhesive spraying assembly.
[0013] The glue pump draws glue from the storage tank into the distribution shell, and then sprays it onto the automotive film through various spray nozzles. The distribution shell is slidably connected to the second bracket along its length. The second bracket is also equipped with a drive component for driving the distribution shell to slide back and forth along its length. The reciprocating movement of the second bracket drives the spray nozzles to move back and forth, expanding the diffusion range of the glue spray. Combined with the delivery of the automotive film, this allows the glue roller to apply the glue more evenly. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0017] like Figure 1 As shown, an adhesive applicator for automotive film processing includes a base 1, on which a guide applicator and an adhesive spraying assembly are provided. The guiding coating assembly includes two first brackets 2, one on the left and one on the right, fixed to the base 1 respectively; guide rollers 3 are rotatably connected to the first brackets 2 respectively; a coating roller 4 is also rotatably connected to the left first bracket 2; a guide roller 5 is also rotatably connected to the right first bracket 2; the guide rollers 3, 4, and 5 are all horizontally arranged and parallel to each other; the coating roller 4 on the left is located above the guide roller 3 on the left, and the gap between them is used to allow the automotive film 6 to pass through; the guide roller 5 on the right is located above the guide roller 3 on the right, and the two are used to clamp the automotive film 6; like Figure 1-2 As shown, the glue spraying assembly includes a second bracket 7 fixed on the base 1; a diversion shell 8 is provided on the upper part of the second bracket 7; the diversion shell 8 is correspondingly spanned across the top of the automotive film 6; the diversion shell 8 is slidably connected to the second bracket 7 along its length; a plurality of glue spraying nozzles 9 facing the automotive film 6 are evenly connected below the diversion shell 8; a glue storage tank 10 and a glue extraction pump 11 are fixed on the base 1; the glue extraction pump 11 is connected to the glue storage tank 10 through a extraction pipe 12, and the glue extraction pump 11 is connected to the diversion shell 8 through a discharge pipe 13; the second bracket 7 is also provided with a driving component for driving the diversion shell 8 to slide back and forth on the second bracket 7 along its own length.
[0018] In this scheme, the automotive film 6 is guided by the coating component and transported by an external transmission device. The automotive film 6 is kept flat and gradually moves under the adhesive spraying component. At this time, the adhesive pump 11 draws the adhesive from the storage tank 10 into the distribution shell 8, and then sprays it onto the automotive film 6 through each spray nozzle 9. The drive component works synchronously to drive the spray nozzle 9 to reciprocate, expanding the diffusion range of the adhesive. When the adhesive spraying range passes under the coating roller 4, it drives the coating roller 4 to rotate, so that the coating roller 4 can achieve the effect of smoothing the adhesive.
[0019] The reciprocating motion of the glue spray nozzle 9 is along the length of the diverter shell 8, which spans across the top of the automotive film 6. In other words, the reciprocating motion of the glue spray nozzle 9 is perpendicular to the transmission direction of the automotive film 6. This arrangement makes the glue spraying range not only more uniform in the width direction of the automotive film 6, but also continuous in the length direction, effectively reducing the phenomenon of excessive concentration of glue spots, making the pressure application of the subsequent glue coating roller 4 more uniform, and improving the glue coating effect on the automotive film 6.
[0020] The two guide rollers 3 are at the same horizontal height. The automotive film part 6 is located in the area between the two guide rollers 3, which ensures that it is horizontal, reduces the problem of glue flow after spraying, and avoids excessive local glue amount affecting the uniformity of subsequent glue application.
[0021] like Figure 1 , Figure 3 As shown, a scraper 14 is provided on the upper side of the coating roller 4; the length direction of the scraper 14 is parallel to the axial direction of the coating roller 4; the scraper 14 is connected to the first bracket 2 on the left side through a connecting rod 15; the lower end of the scraper 14 is in frictional contact with the surface of the coating roller 4.
[0022] The scraper 14 can scrape off the glue on the glue roller 4 when it rotates after the glue has been applied, so that the glue roller 4 only applies the glue to the automotive film 6 when it is applying glue, and will not apply the glue that was previously applied to it to the automotive film 6, thereby improving the uniformity and cleanliness of the glue application.
[0023] like Figure 1 As shown, the connecting rod 15 is detachably connected to the first bracket 2 on the left side via bolt fasteners 16. The connecting rod 15 can be removed, facilitating the removal and cleaning of the scraper plate 14 after a period of time.
[0024] like Figure 1 As shown, a baffle 17 is connected to the side of the scraper 14 where the adhesive accumulates. The baffle 17 provides a storage space for the adhesive scraped off by the scraper 14, preventing excessive adhesive from being scraped off the scraper 14 and falling back onto the coating roller 4.
[0025] like Figure 1 As shown, the coating roller 4 is driven by a first motor 18 connected to the first bracket 2 on the left side. The first motor 18 (selected as a geared motor structure) drives the coating roller 4, enabling the coating roller 4 to rotate on its own, thus achieving the active transmission effect of the device on the automotive film 6.
[0026] like Figure 2As shown, the driving component includes a baffle 19 fixed on one side of the second bracket 7 and a second motor 20 fixed on the other side of the second bracket 7; the baffle 19 is connected to one end of the diverter housing 8 in the length direction by a compression spring 21; a cam 22 is correspondingly sleeved and fixed to the output end of the second motor 20; the cam 22 abuts against the other end of the diverter housing 8 in the length direction; when the distal end of the cam 22 abuts against the diverter housing 8, the compression spring 21 is in a compressed state.
[0027] The second motor 20 (also a geared motor) drives the cam 22 to rotate. The distal end of the cam 22 abuts against the splitter shell 8, pressing the splitter shell 8 against the compression spring 21. When the distal end of the cam 22 deviates, the compression spring 21 gradually rebounds, pushing the splitter shell 8 back. Through the reciprocating motion of the cam 22 and the reciprocating compression and rebound of the compression spring 21, the reciprocating motion of the splitter shell 8 along its length can be achieved.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
