For aesthetic purposes, an inner lining is attached inside the top cover for decoration. During the gluing process of the inner lining, glue can be applied by roller application. In related technologies, the roller application device includes a glue supply component and two rollers. The glue supply component supplies glue to one of the rollers, and the inner lining passes between the two rollers. Thus, the roller with glue on it rolls the glue onto the bonding surface of the inner lining. In some cases, the glue may flow onto the other roller that is not covered with glue, causing the non-bonding surface of the inner lining to also be covered with glue. This may subsequently lead to foreign matter adhering to the non-bonding surface of the inner lining, affecting the quality of the finished product. Utility Model Content This application aims to address at least one of the technical problems existing in the prior art.

[0025] Reference Figures 1 to 4 According to a first aspect embodiment of the present application, the roller coating apparatus includes: a frame 100, a first roller 200, a second roller 300, a tank 400, a scraper 500, and a glue dispensing assembly 600.

[0026] The first roller 200 is rotatably mounted on the frame 100, and the second roller 300 is rotatably mounted on the frame 100. The second roller 300 is located below the first roller 200, and an inner liner passes between the second roller 300 and the first roller 200. The tank 400 has a receiving groove 410 and a water outlet 420. The second roller 300 is at least partially located in the receiving groove 410, and the water outlet 420 is opened on the wall of the receiving groove 410, facing the second roller 300. The scraper 500 is disposed in the tank 400 and abuts against the outer peripheral surface of the second roller 300. The glue dispensing assembly 600 is provided with a glue dispensing port 610, which faces the first roller 200.

[0027] Understandably, the first roller 200 and the second roller 300 roll in opposite directions. Under the rolling action of the first roller 200 and the second roller 300, the liner passes between the first roller 200 and the second roller 300. The glue outlet 610 of the glue dispensing component 600 faces the first roller 200, so that the glue is output onto the first roller 200. When the liner passes between the first roller 200 and the second roller 300, the first roller 200 rolls the glue to the upper side of the liner. The upper side of the liner serves as the bonding surface for the top cover and the bottom cover, so that the upper side of the liner is fully glued. Therefore, when the liner is subsequently bonded to the top cover, the liner and the top cover are tightly bonded and it is not easy for the edges to curl up. At the same time, since the liner is glued to the upper side, it is convenient to support the liner for conveying by the conveyor belt, so that the conveyor belt and the liner will not stick together due to the glue. It is also understandable that in some cases, there is a possibility that glue may flow onto the second roller 300. In order to prevent the second roller 300 from rolling the glue onto the lower side of the lining, which is the non-adhesive surface of the lining, a water outlet 420 and a scraper 500 are provided to clean the second roller 300. Specifically, the water outlet 420 is connected to an external water source and sprays water toward the second roller 300 to wash off the glue adhering to the second roller 300. The wastewater falls into the receiving tank 410 to collect the wastewater. The scraper 500 abuts against the outer peripheral surface of the second roller 300 and can scrape the glue on the second roller 300 into the receiving tank 410.

[0028] In summary, the liner passes between the first roller 200 and the second roller 300. The glue dispensing component 600 dispenses glue towards the first roller 200, allowing the first roller 200 to roll the glue onto the upper side of the liner, ensuring full coverage and improving the tightness of the bond between the liner and the cover, preventing edge lifting. Simultaneously, water is sprayed towards the second roller 300 through the water outlet 420, and a scraper 500 abuts against the outer circumference of the second roller 300 to clean any glue adhering to it. This prevents the second roller 300 from rolling glue onto the lower side of the liner, reducing the risk of glue sticking to the non-bonding surfaces of the liner, thus improving product quality and avoiding interference with subsequent liner conveying and bonding.

[0029] Specifically, in this embodiment, the glue outlet 610 of the glue dispensing assembly 600 is located above the first roller 200, allowing the glue to flow directly onto the first roller 200 under gravity, thus preventing glue splashing. In other embodiments, the glue outlet 610 may also be located diagonally above or horizontally on the first roller 200, allowing glue to be sprayed onto the first roller 200 by spraying.

[0030] Specifically, the water level in the receiving tank 410 is not higher than the lowest point of the second drum 300, so as to avoid secondary pollution of the second drum 300 by sewage.

[0031] Reference Figure 4 According to some embodiments of this application, the tank 400 is further provided with an inlet 430 and a buffer cavity 440. The inlet 430 is connected to the buffer cavity 440 and is used to connect to an external water source. The outlet 420 is connected to the buffer cavity 440 and the receiving tank 410.

[0032] Understandably, the inlet 430 is used to connect with an external water source. Water flows through the inlet 430 into the buffer chamber 440, and the water in the buffer chamber 440 is then sprayed out from the outlet 420. The water flow first passes through the buffer chamber 440 and then sprays out from the outlet 420, which can stabilize the water pressure at the outlet 420. In addition, the outlet 420 has a small diameter, which can pressurize the water flow.

[0033] Reference Figure 3 and Figure 4 According to some embodiments of this application, the tank 400 is also provided with a drain outlet 450, which connects the receiving tank 410 and the water inlet 430. A filter structure (not shown in the figure) is provided between the drain outlet 450 and the water inlet 430.

[0034] Understandably, wastewater in tank 400 can be discharged through drain outlet 450 to prevent water accumulation in tank 400. The discharged wastewater can then be filtered and re-entered through inlet 430, and sprayed out again through outlet 420, achieving water recycling. It is also understandable that drain outlet 450 can be connected to an external sewage pipe to directly discharge wastewater.

[0035] Reference Figure 4 According to some embodiments of this application, the outlet 420 extends along the axial direction of the second roller 300.

[0036] Understandably, there is one outlet 420, which extends along the axial direction of the second roller 300, in order to increase the spray range of the outlet 420.

[0037] In other embodiments, multiple outlets 420 are provided and distributed along the axial direction of the second roller 300.

[0038] Reference Figure 4 According to some embodiments of this application, the scraper 500 is detachably connected to the groove 400.

[0039] It is understandable that the scraper 500 is detachably connected to the groove 400 to facilitate the disassembly and assembly of the scraper 500, thereby making it easier to replace the scraper 500 when it is damaged.

[0040] Reference Figure 4 According to some embodiments of this application, the outlet 420 and the scraper 500 are located on opposite sides of the second roller 300.

[0041] It is understandable that the scraper 500 and the outlet 420 are located on opposite sides of the second roller 300. Specifically, the scraper 500 and the outlet 420 are distributed along the conveying direction of the lining to reduce installation space and achieve a reasonable layout.

[0042] Reference Figure 4 According to some embodiments of this application, the outlet 420 and the scraper 500 are distributed along the rotation direction of the second roller 300.

[0043] It is understandable that, starting from the contact position between the second roller 300 and the lower side of the liner, the contact position will first pass through the outlet 420 and then through the scraper 500. Thus, the scraper 500 can also be used to scrape away the residual water on the second roller 300, preventing the second roller 300 from rolling water onto the liner.

[0044] Reference Figure 4 According to some embodiments of this application, the scraper 500 is disposed at the upper end of the groove 400.

[0045] Understandably, the scraper 500 is positioned at the top of the tank 400 for easy installation. At the same time, since the outlet 420 and the scraper 500 are distributed along the rotation direction of the second roller 300, it can be ensured that the scraper 500 scrapes off the water and glue and drops them into the receiving tank 410.

[0046] Reference Figure 4 According to some embodiments of this application, the scraper 500 extends horizontally in a direction close to the second roller 300.

[0047] Understandably, the scraper 500 is set horizontally and extends horizontally in the direction close to the second roller 300. When the scraper 500 scrapes the water and glue off the second roller 300, the glue falls directly into the receiving groove 410 and does not flow along the extension direction of the scraper 500. This prevents the glue from flowing along the extension direction of the scraper 500 and adhering to the scraper 500, thus affecting the cleaning effect of the scraper 500. Furthermore, it prevents water from flowing along the extension direction of the scraper 500 and from flowing outside the receiving groove 410.

[0048] The lining applicator according to a second aspect of this application includes the glue roller device of the first aspect embodiment.

[0049] The lining applicator according to the second aspect of this application has at least the following beneficial effects: including all the beneficial effects of the roller adhesive device of the first aspect embodiment, which will not be repeated here.

[0050] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
