[0002] Leather is the animal skin that has been denatured and is not easily decayed after physical and chemical processing such as hair removal and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space. Its surface has a special grain layer, with natural grain and luster, and a comfortable hand feeling.

[0003] At present, there are various production methods for leather, including but not limited to spraying, roll coating, etc. The leather produced by different production methods has different properties.

[0004] In the prior art, the roll coating device adheres the coating on the roller and then contacts with the leather to complete the coating operation on the leather. After research, we found that the roller needs a driving source for driving, and the leather also needs a driving source for driving. Therefore, multiple groups of driving sources are required in a set of roll coating device, and the production cost of the equipment is high. For this reason, we propose a leather roll coating device. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation of the present invention.

[0024] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0025] A leather roller coating device, as Figures 1-3 shown, includes a roller 1. The outer wall of the top of the roller 1 is attached with the leather 2 to be coated. And a first roller 3 and a second roller 4 are respectively installed on both sides of the roller 1 to realize the conveying of the leather 2. A driving source for driving the roller 1 is installed at one end of the roller 1. And a driven shaft 5 is installed on the other side of the roller 1. A dye tank 6 for replenishing the roller 1 is arranged below the roller 1. And a support frame 7 for limiting and installing the roller 1 is fixed on the outer wall of the dye tank 6

[0026] Furthermore, in this embodiment, transmission turntables are installed on the outer wall of the driven shaft 5 and on one side outer wall of the second roller 4. And transmission turntables are installed on both sides of the outer wall of the first roller 3. The transmission turntable on the outer wall of the driven shaft 5 is connected to the transmission turntable on one side of the first roller 3 through a transmission belt.

[0027] Please refer to Figure 2 , the transmission turntable on the other side of the first roller 3 is connected to the transmission turntable of the second roller 4 through a transmission belt to realize the rotation of the two groups of rollers.

[0028] Please refer to Figure 3 , a solution chamber 8 is opened inside the dye tank 6. And fuel is filled inside the solution chamber 8. And the solution chamber 8 is also connected to an external feeding system to realize the feeding function for the roller 1.

[0029] Please refer to Figure 3 , a rotating shaft 9 with a transmission turntable installed on the end face is arranged inside the dye tank 6. And a plurality of stirring blades 10 distributed at intervals are fixed on the outer wall of the rotating shaft 9. A second group of transmission turntables are also installed on the end face of the driven shaft 5. And the transmission turntable of this group is connected to the transmission turntable on the end face of the rotating shaft 9 through a transmission belt to realize the driving function for the rotating shaft 9.

[0030] The working principle of the present utility model is as follows: First, an external driving source drives the roller 1 to rotate and drives the driven shaft 5 to rotate synchronously. After the driven shaft 5 rotates, it drives the first roller 3 to rotate through the transmission turntable and transmission belt. The first roller 3 also drives the second roller 4 to rotate through the transmission turntable and transmission belt. At this time, the leather 2 starts to be conveyed, that is, it moves on the outer wall of the roller 1. During the movement, the dye adhered to the outer wall of the roller 1 is smeared on the leather 2, thus completing the roller coating operation on the leather 2;

[0031] It should be noted that the rotation direction of the roller 1 is opposite to the movement direction of the leather 2. Therefore, due to the friction effect, the roller coating quality of the leather 2 will be better;

[0032] Furthermore, while the driven shaft 5 rotates, it also drives the rotating shaft 9 to rotate through the transmission turntable and transmission belt. After the rotating shaft 9 rotates, it drives a plurality of stirring blades 10 on its outer wall to rotate, realizing the stirring effect on the dye and improving the quality of the dye, that is, further improving the roller coating quality of the leather 2.

[0033] Although the embodiments of the present utility model have been shown and described, this specific embodiment is only an explanation of the present utility model, and it is not a limitation of the utility model. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can, without departing from the principle and purpose of the present utility model, make modifications, substitutions and variations that do not contribute creatively to the embodiments as needed. However, as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
