Description

Technical Field

[0001] This utility model relates to the field of leather processing technology, and in particular to a leather coating equipment. Background Technology

[0002] In the leather processing industry, coating is a key process for improving the appearance, texture, abrasion resistance, water resistance, and color richness of leather. The coating effect directly determines the final quality and market competitiveness of leather products. Currently, leather coating processes mainly employ three methods: scraping, spraying, and roller coating. Among these, roller coating has become one of the mainstream coating methods due to its ease of operation and high production efficiency, and is widely used in large-scale leather production.

[0003] Existing leather roller coating equipment involves using a coating roller to pick up coating material from a coating tank and then transferring it to a moving leather surface to complete the coating operation. However, these traditional devices still have many technical shortcomings that need to be addressed in practical applications. For example, the coating material is prone to sedimentation during the coating process, leading to uneven coating concentration and resulting in color differences on the leather surface, affecting product consistency. To solve the coating sedimentation problem, existing equipment usually requires an additional independent stirring mechanism to continuously stir the coating material in the tank, which significantly increases energy consumption and lacks practicality. Secondly, after coating the leather, excess coating material often remains on the surface. If this excess coating material is not removed in time, it will result in serious waste of coating material, increasing production material costs. Furthermore, the excess coating material will prolong the drying time of the leather, reducing production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a leather coating equipment that can simultaneously coat the leather surface with coatings and stir the coating inside the coating tank. This effectively reduces the occurrence of sedimentation in the coating tank due to long-term standing, which affects the coating effect. At the same time, the stirring component and the coating component share a single power source, the motor, which effectively reduces the energy consumption of the equipment. It can also scrape off excess coating from the coated leather surface after coating, thereby effectively reducing coating waste and improving the subsequent drying rate of the leather.

[0005] To achieve the above objectives, a leather coating equipment is provided, comprising:

[0006] A paint tank having a brush roller assembly for applying paint to a leather surface, a stirring assembly for mixing paint inside the paint tank, and a scraper assembly for scraping off excess paint from the leather surface.

[0007] The brush roller assembly includes a motor fixedly connected to the outer surface of the paint tank, a coating roller fixedly connected to the output end of the motor, and a coating cotton layer fixedly connected to the outer surface of the coating roller.

[0008] The mixing assembly includes a conical tooth A fixedly connected to the outer surface of the coating roller away from the motor end, a protective box fixedly connected to the outer surface of the paint tank, a rotating shaft rotatably connected inside the protective box via a bearing, a conical tooth B fixedly connected to the outer surface of the upper end of the rotating shaft, a drive wheel fixedly connected to the outer surface of the lower end of the rotating shaft, a belt drivingly connected to the outer surface of the drive wheel, a connecting shaft rotatably connected to the inside of the paint tank via a sealed bearing, a synchronous pulley fixedly connected to the outer surface of the lower end of the connecting shaft, and a mixing blade fixedly connected to the outer surface of the upper end of the connecting shaft. The outer surface of the synchronous pulley is driven by the belt, and the conical tooth A meshes with the conical tooth B.

[0009] The scraper assembly includes two cavities inside the paint tank, a spring fixedly connected to the inner wall of the bottom of the cavity, a limiting block fixedly connected to the upper end of the spring, a pressure rod fixedly connected to the upper surface of the limiting block, a fixing plate fixedly connected to the upper end of the pressure rod, and a scraper fixedly connected to the upper surface of the fixing plate.

[0010] Preferably, the outer surface of the coating roller is rotatably connected to the coating tank via a bearing.

[0011] Preferably, the inner surface of the cavity is slidably connected to the limiting circular block.

[0012] Preferably, the outer surface of the pressure rod is slidably connected to the paint box.

[0013] Preferably, the uppermost horizontal height of the scraper is greater than the uppermost horizontal height of the coated cotton layer.

[0014] Preferably, the outer surface of the paint box is fixedly connected with four fixing buckles arranged in a rectangular array.

[0015] The above-mentioned solution has the following beneficial effects:

[0016] 1. By setting up a stirring component, the coating inside the coating tank can be stirred while the coating is being applied to the leather surface. This effectively reduces the occurrence of sedimentation in the coating tank due to long-term standing, which affects the coating effect. At the same time, the stirring component and the coating component share the same single power source, the motor, which effectively reduces the energy consumption of the equipment.

[0017] 2. By setting up a scraper assembly, excess paint can be scraped off the leather surface after coating, thereby effectively reducing paint waste and improving the subsequent drying rate of the leather.

The outer surface of the coating roller 3 is fixedly connected to the conical tooth A5, the conical tooth A5 meshes with the conical tooth B8, and the outer surface of the synchronous wheel 12 is drivenly connected to the belt 10.

[0029] Reference Figure 3 and Figure 4 The scraper assembly includes two cavities 14 formed inside the paint tank 1, a spring 15 fixedly connected to the inner wall of the bottom of the cavity 14, a limiting block 16 fixedly connected to the upper end of the spring 15, a pressure rod 17 fixedly connected to the upper surface of the limiting block 16, a fixing plate 18 fixedly connected to the upper end of the pressure rod 17, and a scraper 19 fixedly connected to the upper surface of the fixing plate 18.

[0030] Those skilled in the art should connect all electrical components in this case to their compatible external power supply via wires, and should select a suitable controller according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0031] Working principle: During operation, the leather to be coated is introduced into the external winding device, and the device is placed parallel to the leather below by fixing buckles 20 and bolts. Simultaneously, the coating cotton layer 4 on the coating roller 3 is pressed tightly against the leather coating surface. When the coating cotton layer 4 is in close contact with the leather coating surface, because the uppermost horizontal height of the scraper 19 is greater than the uppermost horizontal height of the coating cotton layer 4, the leather will press down on the scraper 19, driving the fixing plate 18 to move the limiting block 16 at the lower end of the pressure rod 17 downwards along the cavity 14, compressing the spring 15. Under the rebound force of the spring 15, the scraper 19 will remain in close contact with the leather coating surface. Subsequently, during the leather winding process, the motor 2 is started, driving the coating roller 3 to rotate the coating cotton layer 4. When the coating cotton layer 4 rotates into the paint tank 1, it will contact the paint inside the paint tank 1 and adhere to its surface. When the coating cotton layer 4 rotates again to the leather coating surface, it will apply the coating to the leather, thus completing the coating operation. At the same time as the coating roller 3 rotates, the meshing action of the conical teeth A5 and B8 will synchronously drive the drive wheel 9 on the rotating shaft 7 to rotate. Then, under the transmission action between the drive wheel 9, belt 10, connecting shaft 11 and synchronous wheel 12, the stirring blade 13 will rotate inside the coating tank 1, thereby stirring the coating inside to reduce the precipitation of the coating. No additional power components are required, which can effectively reduce the energy consumption of the device. After the leather is coated with the coating, it will pass through the scraper 19. Under the close contact between the scraper 19 and the leather, the scraper 19 will scrape off the excess coating on the surface of the leather and let it fall into the coating tank 1 for collection again, thereby effectively reducing the waste of coating and improving the drying rate of the leather.
