Description

Technical Field

[0001] The present application relates to the field of glue coating machines, and in particular to a high-precision glue coating device. Background Art

[0002] Leather is a denatured, non-perishable animal hide obtained through physical and chemical processes such as dehairing and tanning. Leather is composed of natural protein fibers tightly woven in three dimensions. Its surface features a unique grain layer, resulting in a natural texture, sheen, and pleasant feel. To enhance the leather's lifespan and quality, it is typically coated with glue. Gluing involves applying a coating (including solvent-based, latex, and water-based) to the fabric surface using a coating machine.

[0003] In the prior art, common gluing equipment primarily consists of a frame, on which are mounted an unwinding mechanism, a tension control mechanism, a rewinding mechanism, a gluing mechanism, and a cooling and drying mechanism. The unwinding mechanism unwinds the raw material coil at a constant speed. The coil is then driven by the tension control mechanism and passes through the gluing mechanism. After the coated coil is delivered by the gluing mechanism, the cooling and drying mechanism cools the coil to dry the adhesive on the coil surface. The dried coil is then rewound by the rewinding mechanism.

[0004] Among them, the common gluing mechanism includes a gluing machine frame, on which a gluing roller and a scraper are rotatably installed. The coil is sent out by the unwinding mechanism and passes through the surface of the gluing roller. The scraper is fixedly installed on the side of the gluing roller. The coil passes between the roller surface of the gluing roller and the scraper. The scraper makes the coil fit with the roller surface of the gluing roller to complete the gluing process on the surface of the coil.

[0005] However, the position of the scraper of common glue coating equipment is fixed. When the coil passes between the scraper gun and the glue coating roller, the pressure between the coil and the glue coating roller is a fixed value and the amount of glue attached to the coil is fixed. However, in the actual production and processing process, the thickness of the glue that needs to be coated on the coil is different, and the existing scraper cannot be adjusted, which makes it difficult to meet the needs of coating processing of glue of different thicknesses. There is room for improvement. Utility Model Content

[0006] In order to facilitate the operator to adjust the position of the scraper and improve the convenience of the operator in using the gluing equipment, the present application provides a high-precision gluing device.

[0007] The high-precision glue coating device provided in this application adopts the following technical solution:

[0008] A high-precision gluing device comprises a frame, a mounting bracket is slidably mounted on the frame, a connecting seat is adjustably mounted on the mounting bracket, a scraper is mounted on the connecting seat, and angle adjustment mechanisms are respectively installed between the two ends of the connecting seat and the mounting bracket;

[0009] Two driving members are fixedly mounted on the frame, and driving ends of the two driving members are fixedly connected to two ends of the mounting bracket. The two driving members drive the mounting bracket to slide toward or away from the glue coating roller.

[0010] By adopting the above technical solution, during the actual gluing process using the gluing equipment, the operator can drive the mounting bracket and the scraper on the mounting bracket to slide toward or away from the gluing roller by controlling the driving member according to the actual gluing thickness requirements. The contact pressure between the coil and the gluing roller can be adjusted by adjusting the position of the scraper, thereby achieving the technical effect of adjusting the thickness of the glue on the coil. During the actual adjustment process, since an angle adjustment mechanism is provided between the two ends of the connecting seat and the mounting bracket, the operator can adjust the angle of the scraper according to the position of the scraper to ensure that the coil fits on the roller surface of the gluing roller.

[0011] Preferably, the frame includes two opposite side panels, a rotating shaft is installed between the two side panels, and both ends of the rotating shaft are rotatably installed on the two side panels respectively;

[0015] By adopting the above technical solution, the technical effect of a sliding connection between the mounting bracket and the rack can be achieved through the rack at the bottom of the mounting plate and the gear installed between the two side plates. The sliding connection between the mounting bracket and the rack is achieved through the cooperation of the gear rack, which can improve the smoothness of the sliding movement of the mounting bracket.

[0017] By adopting the above technical solution, when the driving member drives the mounting bracket to slide, the slider fixed on the mounting plate slides along the axial direction of the guide rail, which can limit the sliding tracks of the two mounting plates and the mounting bracket.

[0018] Preferably, the driving member comprises a telescopic cylinder, the cylinder body of the telescopic cylinder is fixedly mounted on the side plate, and the cylinder shafts of the two telescopic cylinders are fixedly connected to the two mounting plates respectively.

[0020] Preferably, connecting plates are fixedly mounted on both ends of the connecting seat, and the two connecting plates are rotatably connected to the two mounting plates via rotating shafts.

[0023] By adopting the above technical solution, the technical effect of the rotational connection between the connecting plates on both sides of the connecting seat and the two mounting plates can be achieved through the rotating shaft. In combination with the first adjustment seat, the second adjustment seat and the first screw rod between the connecting plate and the mounting plate, when the angle of the scraper plate needs to be adjusted, the angle of the first adjustment seat and the second adjustment seat can be adjusted by rotating the first screw rod to achieve the technical effect of adjusting the angle of the connecting seat and the scraper plate.

[0024] Preferably, a slide rail is fixedly installed on the top of the connecting seat, two sliding seats are slidably installed on the slide rail, and a scraping seat for mounting the scraping plate is fixedly installed on the top of the two sliding seats;

[0026] A plurality of guide rods are fixedly installed between the first support and the second support, and the scraper seat is slidably installed on the plurality of guide rods.

[0027] By adopting the above technical solution, during the actual production and processing process, the operator can drive the second screw to rotate in different directions by adjusting the rocker according to the position of the coil, so that the scraper seat on which the scraper plate is installed slides axially along the slide rail, which can facilitate the operator to adjust the position of the scraper plate. At the same time, during the sliding process of the scraper seat, the scraper seat can be restricted by a number of guide rods to reduce the occurrence of scraper seat offset and scraper plate offset.

During the actual adjustment process, since an angle adjustment mechanism is provided between the two ends of the connecting seat and the mounting bracket, the operator can adjust the angle of the scraper according to the position of the scraper to ensure that the web is adhered to the roller surface of the gluing roller.

[0030] 2. During the actual production and processing process, the operator can drive the second screw to rotate in different directions by adjusting the rocker according to the position of the coil, so that the scraper seat on which the scraper is installed slides along the axial direction of the slide rail, which makes it easier for the operator to adjust the position of the scraper.
