Description

Technical Field

[0001] This utility model relates to the field of leather processing technology, and in particular to a leather cleaning device after dyeing for leather processing. Background Technology

[0002] Existing leather processing cleaning devices after dyeing are mainly used to remove excess dye from leather surfaces after dyeing, as not all dyes adhere firmly to the leather. The cleaning device can remove these excess dyes by spraying water or rinsing, using the flushing action of the water flow.

[0003] However, during its use, it lacks components to optimize the hot air blowing effect during the drying process. The hot air tends to be concentrated and blown directly, and local overheating can cause the moisture in the leather fibers to evaporate quickly. This may damage the fiber structure, making it fragile and easy to break. In subsequent processing or use, the leather is prone to cracks and breaks, reducing the durability and lifespan of leather products. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a leather cleaning device after dyeing for leather processing. After rinsing, the leather is carried to the bottom of the air duct. The active fan blades and heating plate can blow hot air onto the surface of the leather. During this process, the airflow blown by the active fan blades will drive the driven fan blades to rotate, which will drive the baffle plate to rotate and disturb the airflow. This will prevent the hot air from being concentrated and blown directly onto the leather, making the hot airflow more evenly distributed on the surface of the leather, reducing the risk of local overheating of the leather, helping to protect the fiber structure of the leather, and avoiding problems such as hardening, brittleness or loss of elasticity of the leather due to high temperature, thus maintaining the original softness and toughness of the leather.

[0005] This utility model also provides a leather dyeing and cleaning device for leather processing, comprising: a cleaning box, a plurality of conveying rollers rotatably connected to the inner surface of the cleaning box, a conveyor belt rotatably connected to the outer wall of the plurality of conveying rollers, a plurality of support rods fixedly connected to the inner surface of the cleaning box, a nozzle fixedly connected to the lower surface of the support rods, a connecting pipe fixedly connected to the side surface of the cleaning box, the connecting pipe communicating with the nozzle, an interface provided on the connecting pipe, a second bracket fixedly connected to the upper surface of the cleaning box, an air duct penetrating the inner surface of the second bracket, a first fixing frame fixedly connected to the inner wall of the air duct, a third motor fixedly connected to the inner surface of the first fixing frame, an active fan blade fixedly connected to the output end of the third motor, a heating plate fixedly connected to the inner wall of the air duct, a second fixing frame fixedly connected to the inner wall of the air duct, a rotating shaft rotatably connected to the inner surface of the second fixing frame, a driven fan blade fixedly connected to the upper end of the rotating shaft, and a baffle fixedly connected to the lower end of the rotating shaft.

[0006] According to the present invention, a leather cleaning device for leather processing after dyeing is provided, wherein a motor is fixedly connected to the side surface of the cleaning box, and the conveying roller is driven by the motor.

[0007] According to the present invention, a leather cleaning device for leather processing after dyeing is provided, wherein a bracket is fixedly connected to the upper surface of the cleaning box, and a hydraulic rod is fixedly connected to the lower surface of the bracket.

[0008] According to the present invention, a leather cleaning device for leather processing after dyeing is provided, wherein a hydraulic cylinder is fixedly connected to the upper surface of the bracket, and the hydraulic rod is driven by the hydraulic cylinder.

[0009] According to the present invention, a leather cleaning device for leather processing after dyeing is provided, wherein a support plate is fixedly connected to the lower end of the hydraulic rod, a rotating rod is rotatably connected to the lower surface of the support plate, and a brush is fixedly connected to the lower end of the rotating rod.

[0010] According to the present invention, a leather dyeing and cleaning device for leather processing is provided, wherein a second motor is fixedly connected to the upper surface of the support plate, and the rotating rod is driven by the second motor.

[0011] According to the present invention, a leather cleaning device for leather processing after dyeing is provided, wherein a drain pipe is connected to the lower surface of the cleaning box, and a sealing plug is movably connected to the inner wall of the drain pipe.

[0012] According to the present invention, a leather cleaning device for leather processing after dyeing is provided, wherein a protective plate is fixedly connected to the upper end of the air duct, and an air outlet is provided on the protective plate.

[0013] Compared with existing technologies, this leather processing and post-dyeing cleaning device, after rinsing, brings the leather to the bottom of the air duct. The active fan blades, in conjunction with the heating plate, blow hot air onto the leather surface. During this process, the airflow from the active fan blades drives the driven fan blades to rotate, which in turn drives the baffle to rotate, disturbing the airflow. This prevents the hot air from being concentrated and blown directly onto the leather, making the hot airflow more evenly distributed on the leather surface. This reduces the risk of localized overheating of the leather, helps protect the leather's fiber structure, and avoids problems such as hardening, brittleness, or loss of elasticity caused by high temperatures, thus maintaining the leather's original softness and toughness.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model provides a leather cleaning device for leather processing after dyeing, which includes: a cleaning box 9, a drain pipe 19 connected to the lower surface of the cleaning box 9, a sealing plug 20 movably connected to the inner wall of the drain pipe 19, a plurality of conveying rollers 27 rotatably connected to the inner surface of the cleaning box 9, a motor 12 fixedly connected to the side surface of the cleaning box 9, the conveying rollers 27 being driven by the motor 12, and a conveyor belt 5 rotatably connected to the outer wall of the plurality of conveying rollers 27.

[0023] Specifically: After the motor 12 starts, it drives the conveyor roller 27 inside the cleaning box 9 to rotate. Since multiple conveyor rollers 27 are connected to each other through the conveyor belt 5, the rotation of the conveyor rollers 27 will drive the conveyor belt 5 to circulate. The dyed leather is placed on the conveyor belt 5. As the conveyor belt 5 moves, the leather will be transported to the cleaning and drying areas in sequence, realizing the continuous transport of leather in the device.

[0024] Multiple support rods 3 are fixedly connected to the inner surface of the cleaning box 9. A nozzle 4 is fixedly connected to the lower surface of the support rod 3. A connecting pipe 10 is fixedly connected to the side surface of the cleaning box 9. The connecting pipe 10 communicates with the nozzle 4. An interface 11 is provided on the connecting pipe 10. A bracket 2 is fixedly connected to the upper surface of the cleaning box 9. A hydraulic rod 14 is fixedly connected to the lower surface of the bracket 2. A hydraulic cylinder 13 is fixedly connected to the upper surface of the bracket 2. The hydraulic rod 14 is driven by the hydraulic cylinder 13. A support plate 16 is fixedly connected to the lower end of the hydraulic rod 14. A rotating rod 17 is rotatably connected to the lower surface of the support plate 16. A motor 15 is fixedly connected to the upper surface of the support plate 16. The rotating rod 17 is driven by the motor 15. A brush 18 is fixedly connected to the lower end of the rotating rod 17.

[0025] Specifically: External cleaning fluid enters the connecting pipe 10 through interface 11. Since the connecting pipe 10 is connected to the nozzle 4, the cleaning fluid is sprayed out through the nozzle 4. The nozzle 4 is fixed on the support rod 3. Multiple nozzles 4 can spray water to clean the leather on the conveyor belt from different positions. The flushing action of the water flow removes the floating color and impurities from the leather surface. At the same time, the hydraulic cylinder 13 drives the hydraulic rod 14 to move up and down. The support plate 16 connected to the lower end of the hydraulic rod 14 moves up and down accordingly, thereby adjusting the contact pressure between the brush 18 and the leather surface. The motor 15 starts, driving the rotating rod 17 to rotate. The brush 18 at the lower end of the rotating rod 17 also rotates. The rotating brush 18 can scrub the leather surface, further enhancing the cleaning effect and ensuring that the stains and floating color on the leather surface are thoroughly removed.

[0026] A bracket 21 is fixedly connected to the upper surface of the cleaning box 9. A duct 8 is connected through the inner surface of the bracket 21. A protective plate 7 is fixedly connected to the upper end of the duct 8. An air outlet 6 is provided on the protective plate 7. A fixing frame 1 22 is fixedly connected to the inner wall of the duct 8. A motor 3 21 is fixedly connected to the inner surface of the fixing frame 1 22. An active fan blade 23 is fixedly connected to the output end of the motor 3 21. A heating plate is fixedly connected to the inner wall of the duct 8. A fixing frame 28 is fixedly connected to the inner wall of the duct 8. A rotating shaft 25 is rotatably connected to the inner surface of the fixing frame 28. A driven fan blade 24 is fixedly connected to the upper end of the rotating shaft 25. A baffle 26 is fixedly connected to the lower end of the rotating shaft 25.

[0027] Specifically: After being cleaned, the leather moves along the conveyor belt 5 to the bottom of the air duct 8. The motor 21 starts, driving the active fan blade 23 to rotate. The airflow generated by the rotation of the active fan blade 23 blows downwards onto the leather surface. At the same time, the heating plate on the inner wall of the air duct 8 is energized and heats up, heating the air passing through, turning the air blown onto the leather into hot air. The hot air accelerates the evaporation of moisture from the leather surface, achieving the drying of the leather. The airflow blown out by the active fan blade 23 drives the driven fan blade 24 to rotate. The driven fan blade 24 is connected to the baffle 26 through the rotating shaft 25. Therefore, the rotation of the driven fan blade 24 will drive the baffle 26 to rotate together. When the baffle 26 rotates, it will disturb the hot airflow, so that the hot air is not concentrated and blown directly onto the leather, but is distributed more evenly on the leather surface.

[0028] Working principle: During use, the dyed leather is placed on the conveyor belt 5. As the conveyor belt 5 moves, external cleaning fluid enters the connecting pipe 10 through the interface 11. The cleaning fluid is sprayed out through the nozzles 4. Multiple nozzles 4 can spray water to clean the leather on the conveyor belt from different positions. The flushing action of the water flow removes the floating color and impurities from the surface of the leather. At the same time, the support plate 16 connected to the lower end of the hydraulic rod 14 moves up and down to adjust the contact pressure between the brush 18 and the surface of the leather. The motor 15 starts, driving the rotating rod 17 to rotate. The brush 18 at the lower end of the rotating rod 17... The rotating brush 18 also rotates, which can scrub the leather surface to further enhance the cleaning effect and ensure that the stains and loose color on the leather surface are thoroughly removed. After cleaning, the leather moves to the bottom of the air duct 8 along the conveyor belt 5. The motor 21 starts and drives the active fan blade 23 to rotate. The airflow generated by the rotation of the active fan blade 23 blows downwards onto the leather surface. At the same time, the heating plate on the inner wall of the air duct 8 is energized and heats up, heating the air passing through, turning the air blown onto the leather into hot air. The hot air accelerates the evaporation of moisture on the leather surface, thus drying the leather.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
