[0041] Combination Figure 1-10 As shown, this embodiment of the present disclosure provides a foam pad PU leather adhesion device, including: a frame (100) on which a support conveyor belt (101) is disposed, and a pressing conveyor belt (102) is disposed on the upper part of the support conveyor belt (101); a glue storage tray (200) disposed on the frame (100) above the support conveyor belt (101); and a glue roller (201) rotatably disposed on the frame (100) above the glue storage tray (200), with the bottom of the glue roller (201) extending into the glue storage tray. Inside the disc (200); pressure roller (202), rotatably mounted on the frame (100) above the rubber roller (201); scraper frame (300), mounted on the frame (100) on one side of the rubber roller (201); scraper (301), hinged on the scraper frame (300), with one side of the scraper (301) closely attached to the side of the rubber roller (201), and several grooves (306) arranged side by side on the side of the scraper (301) that contacts the rubber roller (201).

[0042] The foam pad PU leather adhesion device provided in this embodiment of the invention features a frame that supports the conveyor belt, which in turn supports and transports the foam pad. PU leather can be adhered to the upper surface of the foam pad. The conveyor belt presses the foam pad and PU leather together, ensuring a tight fit and improving adhesion and production efficiency. The bottom of the rubber roller extends into the glue storage tray to adhere the adhesive. PU leather passes between the rubber roller and the pressure roller, with the pressure roller pressing the PU leather firmly against the rubber roller surface. This allows the adhesive on the rubber roller to be evenly coated onto the PU leather. The pressure roller also helps the PU leather spread better on the rubber roller, preventing wrinkles and ensuring a smooth coating process. The adhesive is applied evenly and completely. The scraper is hinged on one side of the glue roller, with the grooved side of the scraper closely attached to the side of the glue roller. When the glue roller rotates, the edge of the groove can be used to scrape off excess glue, controlling the glue thickness. The groove on the scraper can accommodate the passage of glue. Excess glue can be scraped off by the scraper and flow into the glue storage tray. The glue passing through the groove can adhere to the PU leather surface through the glue roller, achieving precise control of the glue layer thickness. This can prevent problems such as dripping or overflowing caused by excessive glue layer thickness. After the glue is applied, the PU leather and foam pad are tightly bonded together by the pressing conveyor belt and the supporting conveyor belt, effectively improving the product molding quality and appearance flatness.

[0043] Optionally, a hinge frame (302) is hinged on the scraper frame (300), and the scraper (301) is reciprocated on the hinge frame (302) in a transverse straight line. The side of the scraper (301) with the groove (302) is pressed against the glue roller (201).

[0044] In this way, the hinge frame can drive the scraper to swing hingedly on the scraper frame, ensuring that the scraper always keeps close to the surface of the glue roller. Even if the diameter of the glue roller changes slightly due to wear or temperature variations, the bonding pressure can be automatically adjusted to ensure stable and uniform glue application. At the same time, the scraper can slide laterally along the hinge frame, effectively avoiding uneven glue application caused by local wear. Through the lateral reciprocating sliding of the scraper on the hinge frame, and the continuous rotation of the glue roller, the glue passing through the grooves can form an S-shaped distribution on the glue roller, further improving the uniformity and precision of glue application. At the same time, the S-shaped distribution can effectively slow down the flow rate of the glue, allowing the glue to be distributed more evenly on the glue roller. This allows the glue to adhere better to the PU leather surface, reducing the problem of uneven glue application, and enabling better adhesion between the PU leather and the foam pad, increasing adhesion strength and product yield.

[0045] Optionally, a swing wheel (400) is provided on the side of the hinge frame (302) away from the scraper (301), and a hinge rod (401) is hinged to the side of the swing wheel (400), and the hinge rod (401) is hinged to the scraper (301).

[0046] In this way, a swing wheel is rotatably installed on the hinge frame. The swing wheel is driven to rotate by a motor. A hinge rod is hinged to one side of the swing wheel, and the other end of the hinge rod is hinged to the scraper. The rotation of the swing wheel can drive the hinge rod to drive the scraper to make a reciprocating swing motion on the hinge frame. This allows the scraper to slide laterally in a straight line while closely adhering to the rubber roller. This can spread the glue on the surface of the rubber roller into a uniform S-shaped trajectory, further improving the continuity and thickness consistency of the glue coating.

[0047] Optionally, a push tube (500) is provided on the side of the hinge frame (302) away from the rubber roller (201), and a push spring (501) is provided inside the push tube (500), and the push spring (501) is pressed against the bottom side of the hinge frame (302).

[0048] In this way, a push tube is set on the side of the hinge frame away from the rubber roller, and a push spring is set inside the push tube. The push tube can increase the stability of the spring. One end of the push spring abuts against the inner wall of the push tube, and the other end is connected to the hinge frame. The push spring can always apply elastic pressure to the hinge frame towards the rubber roller, ensuring that the scraper can maintain stable contact with the rubber roller under different working conditions, and preventing the scraper from losing contact due to external vibration or unevenness of the rubber roller surface.

[0049] Optionally, a sliding guide rod (303) is provided on the side of the hinge frame (302) near the scraper (301). The scraper (301) has a groove (304) that matches the sliding guide rod (303), and the width of the groove (304) is greater than the width of the sliding guide rod (303). The groove (304) is sleeved on the sliding guide rod (303).

[0050] In this way, a sliding guide rod is provided on the side of the hinge frame near the scraper, and a groove matching the sliding guide rod is provided on the scraper. The width of the groove is greater than the width of the sliding guide rod. The width of the groove is designed to allow the scraper to slide freely laterally on the sliding guide rod, while limiting its vertical offset, thereby ensuring that the scraper maintains a stable contact angle and movement trajectory during the movement.

[0051] Optionally, a push rod (502) is slidably disposed inside one end of the push tube (500), one end of the push rod (502) is pressed against one end of the push spring (501) inside the push tube (500), and the other end of the push rod (502) is abutted against one side of the bottom of the hinge frame (302). A connecting groove (305) is provided on the hinge frame (302), and the push rod (502) is abutted against the connecting groove (305).

[0052] In this way, a push rod is slidably installed inside one end of the push tube. One end of the push rod is pressed against one end of the push spring, and the other end is pressed against the connecting groove at the bottom of the hinge frame. The elastic force of the spring is transmitted through the extension and retraction of the push rod, so that the hinge frame maintains a stable preload pressure during the swinging process, effectively compensating for the movement gap. The push rod can play a role in the stable connection between the push tube and the hinge frame, preventing tilting or eccentric force phenomena that may occur when the push spring is directly connected to the hinge frame. The connecting groove on the hinge frame is designed as a concave structure, which can effectively limit the end of the push rod and prevent it from slipping laterally during operation, ensuring the stable transmission of elastic force.

[0053] Optionally, support plates (103) are provided on both sides of the frame (100), and connecting plates (104) are provided on both sides of the pressing conveyor belt (102). A pressing rod (105) is vertically provided on the connecting plate (104). The pressing rod (105) is inserted into the support plate (103) and passes through the support plate (103). A limit nut (106) is provided at the end of the pressing rod (105), and a pressing spring (107) is provided between the limit nut (106) and the support plate (103).

[0054] In this way, support plates are set on both sides of the frame, and pressing rods are vertically set on the connecting plates on both sides of the pressing conveyor belt. The pressing rods are inserted into the support plates and pass through the support plates. The end of the pressing rod is set with a limit nut. An adjusting spring is sleeved on the pressing rod between the limit nut and the support plate. By adjusting the elastic force of the spring, the pressing conveyor belt can be pulled downward to maintain a constant pressure. This can keep the pressing conveyor belt and the support conveyor belt in constant pressure contact, and can make the PU leather and foam pad between the pressing conveyor belt and the support conveyor belt tightly bonded.

[0055] Optionally, a support tube (108) is provided on the upper part of the support plate (103), and the support tube (108) is sleeved on the pressing rod (105).

[0056] In this way, the support tube on the support plate can act as a support for the connecting plate, which can support the pressing conveyor belt and keep it at a certain height when it is not in operation. The height between the pressing conveyor belt and the support conveyor belt is less than the thickness of the PU leather and the foam pad. This ensures that the PU leather and the foam pad can be pressed together smoothly when the pressing conveyor belt comes into contact with the support conveyor belt. The support tube can also prevent the pressing conveyor belt from sagging and coming into contact with the support conveyor belt when there is no material passing through.

[0057] Optionally, the pressure roller (202) is provided with sliders (203) at both ends, the sliders (203) are slidably disposed on the frame (100), a pull plate 204 is provided on the frame 100 below the sliders (203), a pull rod 205 is provided at the lower part of the sliders (203), the pull rod 205 passes through the pull plate 204, a pull nut 206 is provided at the end of the pull rod 205, and a pull spring 207 is provided between the pull nut 206 and the pull plate 204.

[0058] In this way, the sliders at both ends of the pressure roller can slide on the frame, thereby adjusting the distance between the pressure roller and the rubber roller 204. This allows for pressure adjustment of the PU leather on the rubber roller to accommodate PU leather materials of different thicknesses and ensure the pressing effect. The pull rod at the bottom of the slider passes through the pull plate, and an adjusting spring is provided between the pull nut at its end and the pull plate. By tightening or loosening the pull nut, the spring pressure can be adjusted, thereby controlling the pressing force applied by the pressure roller to the PU leather. This allows for the accumulation of adhesive between the PU leather and the rubber roller, ensuring even distribution of the adhesive and avoiding uneven distribution or localized lack of adhesive.

[0059] Optionally, a feeding rack (109) is provided on the upper part of the frame (100) away from the pressing conveyor belt (102), and a feeding roller (110) is provided on the upper part of the feeding rack (109).

[0060] In this way, a feeding rack is set on the side of the upper part of the frame away from the pressing conveyor belt. The feeding roller on the feeding rack can store PU leather raw materials, and the PU leather is smoothly conveyed between the pressing roller and the rubber roller by the rotation of the feeding roller, ensuring the continuity and stability of feeding.
