Description

Technical Field

[0001] This utility model relates to the field of leather surface coating technology, and in particular to a leather surface coating device for uniform application. Background Technology

[0002] With the continuous improvement of living standards, people's demand for cow leather is increasing, leading to the rapid development of the cow leather production industry. Cow leather is made by chemically treating and physically processing raw cowhide into a product that is not easily rotten and has properties such as flexibility and breathability. Leather surface coating equipment is required when processing cow leather.

[0003] According to the authorized announcement number CN219839736U, a surface coating device for cow leather production is provided. By installing a wiping device inside the mounting box, the cow leather can be transmitted along the transmission chamber. When the cow leather passes the bottom of the mounting box, the gauze comes into contact with the surface of the cow leather under the action of the grinding disc and the second motor. At the same time as the polishing is completed, the coating liquid is evenly applied to the surface of the cow leather, completing the initial coating of the cow leather surface. Furthermore, by installing a second stand, a drain pipe and a diverter plate on the upper part of the transmission seat, the coating liquid can be continuously dripped onto the surface of the cow leather through the drain pipe.

[0004] However, the surface coating device for cow leather production mentioned above still has shortcomings. After the leather surface is coated, it is inconvenient to dry the coating liquid. During the winding process, the cow leather is prone to sticking together due to the coating liquid, which affects the quality of the cow leather. In addition, it is inconvenient to stir the coating liquid during application, and the coating liquid is prone to sedimentation, resulting in uneven application. Therefore, we propose a leather surface coating device that can apply the coating evenly to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a leather surface coating device for even application.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A leather surface coating device for uniform coating includes a coating box for coating leather surfaces, a partition fixedly connected inside the coating box, inlets and outlets on both sides of the coating box, a drive motor fixedly connected to the front of the coating box, a coating roller fixedly connected to the output shaft of the drive motor, a material box fixedly connected to the top of the coating box, a uniform feeding mechanism provided between the material box, the coating roller and the coating box, and a full drying mechanism provided inside the coating box on the right side of the partition.

[0008] As a preferred embodiment of this utility model, the uniform feeding mechanism includes a servo motor fixedly connected to one side of the material box and a material pump fixedly connected to the inner wall of the top of the coating box. A stirring shaft is fixedly connected to the output shaft of the servo motor, and several stirring rods are fixedly connected to the outer side of the stirring shaft. The material pump is connected to the bottom of the material box, and a feeding pipe is fixedly connected to the bottom of the material pump.

A driven bevel gear is fixedly connected to the top end of the rotating shaft, and the driving bevel gear meshes with the driven bevel gear. A semi-circular gear is fixedly connected to the bottom end of the rotating shaft. Upper racks are fixedly connected to the inner walls of the front and rear sides of the frame, and the semi-circular gears mesh alternately with the two upper racks. Two sliders are fixedly connected to the bottom of the frame, and lower racks are fixedly connected to the bottom of the two sliders. External gears are fixedly sleeved on the outer sides of the three hollow tubes, and the lower racks mesh with the two external gears. Multiple air outlets are fixedly connected to the bottom of the hollow tubes.

[0011] In a preferred embodiment of this invention, the partition and the coating box are fixedly connected by the same guide rod, and both sliders are slidably sleeved on the outside of the guide rod.

[0012] As a preferred embodiment of this utility model, a sealing cover is fixedly connected to the front side of the coating box, the sealing cover is connected to the front end of three hollow tubes, and a hot air blower is fixedly connected to the bottom of the sealing cover.

[0013] As a preferred embodiment of this invention, multiple air outlets are distributed at equal intervals based on hollow tubes.

[0014] As a preferred embodiment of this invention, two guide rollers for guiding the leather are rotatably connected to the inner walls of the front and rear sides of the coating box.

[0015] In this utility model, a leather surface coating device for uniform coating is described. The guide roller facilitates the guidance of the leather. The coating roller is rotated by a drive motor to perform the coating operation on the leather. The stirring shaft and stirring rod are rotated by a servo motor to stir the coating liquid, thereby avoiding uneven sedimentation that would affect the uniformity of the subsequent coating. The coating liquid is pumped from the material tank into the supply pipe by a material pump, and finally flows onto the coating roller to replenish the coating liquid.

A hot air blower blows hot air into the sealing cover and three hollow tubes, and finally, hot air is blown out from multiple air outlets to dry the leather. At the same time, the stirring shaft drives the rotation of the active bevel gear, which in turn drives the rotation of the driven bevel gear, the rotating shaft, and the semi-circular gear. The semi-circular gear and the two upper racks mesh alternately, thereby driving the frame, the two sliders, and the lower rack to reciprocate left and right. The lower rack drives the three external gears and the hollow tubes to rotate in opposite directions. The hollow tubes drive the multiple air outlets to swing left and right, thus reciprocating and swinging to dry the freshly coated leather, making the drying more even and comprehensive, and the drying effect better.

[0017] This utility model has a reasonable structural design. Through multiple air outlets that swing back and forth, it can perform a back-and-forth drying operation on the freshly coated leather, making the drying more uniform and comprehensive, and the drying effect better. It avoids the cow leather from sticking together due to the coating liquid when it is rolled up because it is not dried, thus ensuring the quality of the cow leather. It can also stir the coating liquid to avoid uneven coating caused by uneven sedimentation. Attached Figure Description
