[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1-5 As shown, the embodiments of this utility model include:

[0023] An adhesive application device for automotive plastic parts includes a coating roller 1, a lifting platform 2, a belt conveyor 3, a steel roller 4, an end plate 5, a reduction motor 6, a chain and sprocket assembly 7, a first crossbar 8, dispensing valves 9, and an adhesive pressure tank 10. The coating roller 1 is suspended on the belt conveyor 3 by the lifting platform 2. The roller surface of the coating roller 1 is equipped with a steel roller 4. The steel roller 4 and the coating roller 1 are mounted on a pair of end plates 5. The end plates 5 are equipped with a reduction motor 6 that drives the coating roller 1. The steel roller 4 and the coating roller 1 are connected by a chain and sprocket assembly 7. The end plates 5 are equipped with a first crossbar 8, on which several dispensing valves 9 are attached. The dispensing valves 9 are arranged on the upper side of the roller surface of the coating roller 1 and are externally connected to the adhesive pressure tank 10.

[0024] The chain and sprocket assembly 7 includes a first sprocket 701, a second sprocket 702, a third sprocket 703, and a chain 704. The first sprocket 701 is located at the end of the rubber-coated pressure roller 1, the second sprocket 702 is located at the end of the steel roller 4, and the third sprocket 703 is located on the surface of the end plate 5. The chain 704 is tensioned between the first sprocket 701 and the third sprocket 703, and the second sprocket 702 is pressed against the outside of the chain 704.

[0025] Furthermore, the end plate 5 has an opening and step-shaped retaining strips 501 are horizontally arranged on the upper and lower sides of the opening. A horizontal channel covering the opening is formed between the retaining strips 501, and a bearing seat 502 for carrying the steel roller 4 is engaged in the horizontal channel.

[0026] Furthermore, a travel limit stop 503 is provided in the extension direction of the horizontal channel. One end of the bearing seat 502 is provided with a spring 504 that abuts against the travel limit stop 503, and the other end is provided with a traction screw 504 that is threaded through the travel limit stop 503. The traction screw 504 is externally connected to a handwheel 506 via a pair of right-angle bevel gear sets 505.

[0027] Furthermore, sealing rings 401 are embedded at both ends of the roller surface of the steel roller 4, and the sealing rings 401 are interference-fitted between the steel roller 4 and the rubber-coated pressure roller 1.

[0028] Furthermore, the end plate 5 is provided with a second crossbar 507 on the downstream side of the rubber-coated roller 1. A scraper 508 is installed on the second crossbar 507. The scraper 508 has a sharp edge, which is obliquely downward against the roller surface of the rubber-coated roller 1.

[0029] Furthermore, the lifting platform 2 is composed of a servo motor and two right-angle steering gears connected by a drive shaft. The right-angle steering gears are connected to the lifting screws, and the end plate 5 is suspended on the lifting screws.

[0030] Furthermore, the elevator 2 is mounted on top of a portal frame, and the side wall of the portal frame is provided with a linear guide slider, and the end plate 5 is fixed on the linear guide slider.

[0031] Furthermore, two optical shafts 520 are mounted between the end plates 5. The optical shafts 520 are suspended by a locking linear bearing 521 and a pair of overflow baffles 522 arranged on the upper side of the seam between the steel roller 4 and the rubber-coated pressure roller 1. The overflow baffles 522 have two arc edges that respectively fit the roller surface of the steel roller 4 and the roller surface of the rubber-coated pressure roller 1.

[0032] Furthermore, the outer wall of the adhesive pressure tank 10 is covered with a heating jacket, and the adhesive pressure tank 10 is replaced by a cleaning agent pressure tank 11. The adhesive pressure tank 10 or the cleaning agent pressure tank 11 is mounted on an electronic scale. A rodless cylinder slide 301 is vertically connected to the outside of the belt conveyor 3. An extension plate 302 is provided on the rodless cylinder slide 301. A waste liquid tray 303 is installed on the extension plate 302. The length of the extension plate 302 is greater than the width of the belt conveyor 3. The extension plate 302 is higher than the belt conveyor 3. The waste liquid tray 303 is matched to the steel roller 4 and the rubber-coated pressure roller 1 in a timely manner through the rodless cylinder slide 301.

[0033] like Figure 1 As shown, the rubber-coated pressure roller 3 is lowered by the elevator 2 so that it is attached to the belt conveyor 3.

[0034] like Figure 4 As shown, the diameter of the steel roller 4 is smaller than the diameter of the rubber-coated pressure roller 1, and the central axis of the steel roller 4 and the central axis of the rubber-coated pressure roller 1 are at the same horizontal height.

[0035] like Figure 1 The dispensing valve 9 shown in the figure evenly sprays the glue from the glue pressure tank 10 onto the roller surface of the glue-coating roller 1.

[0036] like Figure 4 As shown, the steel roller 4 spreads the glue evenly on the surface of the rubber-coated pressure roller 1. To prevent glue overflow, a glue overflow baffle 522 is used to intercept the glue that overflows laterally, and a sealing ring 401 is further used to intercept the glue that leaks slightly, so that the glue can only be in the gap between the steel roller 4 and the rubber-coated pressure roller 1.

[0037] like Figure 2 As shown, the geared motor 6 drives the rubber-coated pressure roller 1 to rotate, as... Figure 3As shown, the first sprocket 701 on the rubber-coated roller 1 drives the second sprocket 702 to rotate synchronously via the chain 704, so that the roller surface of the rubber-coated roller 1 is continuously and uniformly coated with glue. The thickness of the glue film on the roller surface of the rubber-coated roller 1 can be further adjusted by the handwheel 506. When the handwheel 506 is rotated, the right-angle bevel gear set 505 drives the traction screw 504 to rotate. The traction screw 504 further drives the bearing seat 502 to move horizontally, thereby changing the axial distance between the two roller shafts. The change in axial distance can change the gap between the roller surfaces, thus changing the thickness of the glue film. In order to prevent the bearing seat 502 from falling off, a retaining strip 501 and a travel limit stop 503 are used for bidirectional limiting.

[0038] like Figure 1 As shown, during production, the reverse side of the automotive plastic part skin (leather material) can be laid on the belt conveyor 3. The leather material arrives at and contacts the rubber coating roller 1 along with the belt conveyor 3, and the glue can be evenly spread on the leather material.

[0039] like Figure 4 As shown, in order to further prevent the leather from rolling back onto the rubber-coated roller 1 during the output process, the scraper 508 is used to poke off the leather adhering to the roller surface.

[0040] After a batch of leather has been coated with adhesive, the residual adhesive on the roller surface needs to be cleaned. For example... Figure 5 The rodless cylinder slide 301 shown pushes the waste liquid tray 303 on the extension plate 302 to the top of the belt conveyor 3, and at the same time, the dispensing valve 9 can be reconnected to the cleaning agent pressure tank 11.

[0041] In summary, this utility model provides an adhesive application device for automotive plastic parts skin. On the one hand, the thickness of the adhesive film is precisely controlled by adjusting the position of the bearing seat through a handwheel. On the other hand, double leakage prevention protection is achieved through an overflow baffle and a sealing ring. Furthermore, a scraper is used to prevent backflow of the skin material, and the cooperation between the lifting platform and the rodless cylinder slide table enables rapid switching between adhesive application and cleaning. This not only significantly improves the uniformity and flexibility of adhesive application, but also greatly improves production efficiency.
