Description

Technical Field

[0001] This utility model relates to the field of leather production technology, specifically to a leather surface cleaning device. Background Technology

[0002] Leather is animal hide that has undergone physical and chemical processing such as hair removal and tanning, resulting in a modified appearance that makes it less prone to decay. Leather is composed of naturally woven protein fibers in a three-dimensional space, and its surface has a special grain layer, giving it a natural grain and luster, and a comfortable feel.

[0003] During human evolution, people discovered that the sap of some plants or mineral oils has a certain tanning effect on leather. Soaking raw hides in these sap enhances their breathability and preservative properties. This, in turn, gives the hides softness, tear resistance, and flexibility. Only at this stage did the leather truly possess the characteristics of genuine leather products.

[0004] During the production and processing of leather, its outer surface needs to be cleaned to remove dust or small particles. This process is mostly carried out using cleaning devices. However, traditional leather surface cleaning devices can only clean one side of the leather. When double-sided cleaning is required, the leather needs to be turned over and the cleaning process needs to be repeated, resulting in low cleaning efficiency and poor practicality. Therefore, this utility model proposes a leather surface cleaning device that can clean both sides of the leather. Utility Model Content

[0005] The purpose of this invention is to provide a leather surface cleaning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leather surface cleaning device, comprising a lower base plate, on both sides of the upper surface of the lower base plate, cleaning frames are fixedly installed, a primary rotating shaft is rotatably installed between the two cleaning frames via bearings, a fixed cleaning roller is fixedly installed on the primary rotating shaft, guide grooves are formed on the upper outer surfaces of the two cleaning frames, the guide grooves are longitudinal grooves, ball screws are rotatably installed in the two guide grooves via bearings, threaded seats are fitted on the outer surfaces of the two ball screws, the threaded seats are threadedly connected to the ball screws, a secondary rotating shaft is rotatably installed between the two threaded seats via bearings, and a movable cleaning roller is fixedly installed on the secondary rotating shaft.

[0007] Preferably, the top ends of both ball screws are fixedly connected to a rotating handle through guide grooves, and the outer surface of the rotating handle is provided with anti-slip ridges.

[0008] Preferably, two symmetrically distributed unwinding frames are fixedly installed on one side of the cleaning frame and on the upper surface of the lower base plate, and an unwinding roller is rotatably installed between the two unwinding frames via a rotating shaft.

[0009] Preferably, one end of the rotating shaft of the unwinding roller is fixedly connected to the output shaft of the unwinding motor, and the unwinding motor is fixedly installed on the outer wall of one of the unwinding frames.

[0010] Preferably, two symmetrically distributed take-up frames are fixedly installed on the other side of the clean and on the upper surface of the lower base plate, and a take-up roller is rotatably installed between the two take-up frames via a rotating shaft.

[0011] Preferably, one end of the rotating shaft of the take-up roller is fixedly connected to the output shaft of the take-up motor, and the take-up motor is fixedly mounted on the outer wall of one of the take-up frames by fixing bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a fixed cleaning roller and a movable cleaning roller in conjunction to simultaneously perform adhesive cleaning on both the upper and lower surfaces of leather materials as they pass through, achieving a double-sided cleaning effect. Compared to traditional single-sided cleaning machines, this invention provides simultaneous double-sided cleaning without the need for secondary turning of the leather, thus significantly improving cleaning efficiency and overall speed in leather processing and production, demonstrating its practicality.

[0014] Meanwhile, this utility model uses a threaded transmission structure to drive the upper movable cleaning roller to move up and down. The movement of the movable cleaning roller can change the gap between the two rollers. In this way, the cleaning roller of this utility model can be used to pass through leather materials of different thicknesses, ensuring the applicability of the cleaning structure. The gap between the two rollers can be dynamically adjusted according to the different thicknesses of leather materials. It has the structural applicability of dynamically adjustable roller gap, adapting to a wider range of leather thicknesses, effectively reducing the limitations of the structure and increasing the scope of application.

[0015] Furthermore, the dynamic adjustment of the gap between the rubber rollers can also adjust the pressing contact force on the leather. When the gap is reduced, the pressing force between the two rubber rollers increases, and the contact between the rubber rollers and the leather becomes tighter. When the gap between the rubber rollers increases, the pressing force between the two rubber rollers decreases. This can prevent the rubber rollers from excessively squeezing and deforming the leather. It has good structural applicability, is more flexible and convenient to use, and is more practical.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4 An embodiment of this utility model provides a leather surface cleaning device, including a lower base plate 1. Cleaning racks 2 are fixedly installed on both sides of the middle of the upper surface of the lower base plate 1. A primary rotating shaft 3 is rotatably installed between the two cleaning racks 2 via a bearing. A fixed cleaning roller 4 is fixedly installed on the primary rotating shaft 3. A guide groove 5 is opened on the upper outer surface of the two cleaning racks 2. The guide groove 5 is a longitudinal groove. A ball screw 6 is rotatably installed in the two guide grooves 5 via a bearing. A threaded seat 7 is sleeved on the outer surface of the two ball screws 6. The threaded seat 7 is threadedly connected to the ball screw 6. A secondary rotating shaft 8 is rotatably installed between the two threaded seats 7 via a bearing. A movable cleaning roller 9 is fixedly installed on the secondary rotating shaft 8.

[0025] In order to facilitate the manual rotation of the ball screw 6, the top of each of the two ball screws 6 passes through the guide groove 5 and is fixedly connected to a rotating handle 10. The outside of the rotating handle 10 is provided with anti-slip ridges, so that the ball screw 6 can be manually driven to rotate in both directions through the rotating handle 10.

[0026] Based on the above structure, in actual use, leather requiring external surface cleaning can be wound and unwound by the winding and unwinding structure. During the unwinding to winding process, the leather material can pass between the fixed cleaning roller 4 and the movable cleaning roller 9. The fixed cleaning roller 4 and the movable cleaning roller 9 can make close contact with the leather material between them. Thus, when the leather is being wound and unwound, the leather and the two rollers can be driven to rotate by the contact friction. Through the rotation of the fixed cleaning roller 4 and the movable cleaning roller 9, dust or small particles on the upper and lower outer surfaces of the leather material can be adhered to the rollers as it passes by, thereby removing impurities from both sides of the leather material and providing a good external surface adhesive cleaning effect.

[0027] This invention utilizes a fixed cleaning roller 4 and a movable cleaning roller 9 working together to simultaneously perform adhesive cleaning on both the upper and lower surfaces of leather materials as they pass through, achieving a double-sided cleaning effect. Compared to traditional single-sided cleaning machines, this invention provides a practical double-sided simultaneous cleaning effect, eliminating the need for secondary turning of the leather for cleaning. This significantly improves the cleaning efficiency of this invention, increases the overall speed of leather processing and production, and demonstrates good practicality.

[0028] Furthermore, when it is necessary to adjust the gap between the two cleaning rollers, two operators can manually rotate the two rotating handles 10 simultaneously. When the two rotating handles 10 rotate simultaneously, they will drive the ball screw 6 to move synchronously. Since the ball screw 6 is threadedly connected to the threaded seat 7, the threaded seat 7 can move up and down when the ball screw 6 rotates. In this way, the up and down movement of the two threaded seats 7 can drive the moving cleaning roller 9 between them to move up and down. The movement of the moving cleaning roller 9 can change the gap between the two rollers. In this way, the cleaning roller of this utility model can be used to pass through leather materials of different thicknesses, ensuring the applicability of the cleaning structure. The gap between the two rollers can be dynamically adjusted according to the leather material of different thicknesses. It has the structural applicability of dynamically adjustable roller gap, and the range of leather thicknesses that can be processed is wider, effectively reducing limitations.

[0029] Furthermore, the dynamic adjustment of the gap between the rubber rollers can also adjust the pressing contact force on the leather. When the gap is reduced, the pressing force between the two rubber rollers increases, and the contact between the rubber rollers and the leather becomes tighter. When the gap between the rubber rollers increases, the pressing force between the two rubber rollers decreases. This can prevent the rubber rollers from excessively squeezing and deforming the leather. It has good structural applicability and the structure is more flexible and convenient to use.

[0030] In this embodiment, as an alternative to the present invention, the fixed cleaning roller 4 and the moving cleaning roller 9 can be replaced with two electrostatic adsorption rollers. In this way, the dust and small particles on the outer surface of the leather can also be adsorbed and removed by the electrostatic adsorption method of the electrostatic adsorption rollers. It has the dual purpose of structure and use. The roller body can be dynamically selected according to the actual use needs.

[0031] In this embodiment, in order to ensure normal unwinding operation, two symmetrically distributed unwinding frames 11 are fixedly installed on one side of the cleaning frame 2 and on the upper surface of the lower base plate 1. An unwinding roller 12 is rotatably installed between the two unwinding frames 11 through a rotating shaft. One end of the rotating shaft of the unwinding roller 12 is fixedly connected to the output shaft of the unwinding motor 13. The unwinding motor 13 is fixedly installed on the outer wall of one of the unwinding frames 11.

[0032] The unwinding motor 13 can drive the unwinding roller 12 to rotate, thereby completing the unwinding process of the leather to be cleaned.

[0033] In this embodiment, in order to facilitate the winding work after unwinding and cleaning, two symmetrically distributed winding frames 14 are fixedly installed on the upper surface of the bottom plate 1 on the other side of the cleaning. A winding roller 15 is rotatably installed between the two winding frames 14 via a rotating shaft.

[0034] One end of the rotating shaft of the take-up roller 15 is fixedly connected to the output shaft of the take-up motor 16, and the take-up motor 16 is fixedly installed on the outer wall of one of the take-up frames 14 by fixing bolts.

[0035] Based on the above structure, the unwound leather can be cleaned by two rubber rollers and then enter the take-up roller 15. The take-up roller 15 is driven by the take-up motor 16 to work, thereby taking the unwound and cleaned leather material into place. Through the combined use of the unwound and take-up structures, the material can be smoothly conveyed between the two rubber rollers, ensuring the normal use of the rubber rollers.

[0036] Working principle: Leather materials that need to be cleaned on the outer surface are wound on the unwinding roller 12. When unwinding, the end of the leather material passes between the fixed cleaning roller 4 and the moving cleaning roller 9, and is finally fixed on the take-up roller 15. Through the cooperation of the unwinding and take-up structures, the material can be smoothly conveyed through the two rollers, ensuring the normal release and take-up of the leather material. During the release and take-up process, the leather material can pass between the two rollers.

[0037] The fixed cleaning roller 4 and the movable cleaning roller 9 can make close contact with the leather material between them. When the leather is being unwound and conveyed, the fixed cleaning roller 4 and the movable cleaning roller 9 can be driven to rotate by the contact friction between the leather and the two rollers. Through the rotation of the fixed cleaning roller 4 and the movable cleaning roller 9, dust or small particles on the upper and lower outer surfaces of the leather material can be adhered by the rollers as it passes by, thereby removing impurities from both sides of the leather material and having a good external surface adhesive cleaning effect.

[0038] This invention utilizes a fixed cleaning roller 4 and a movable cleaning roller 9 working together to simultaneously perform adhesive cleaning on both the upper and lower surfaces of leather materials as they pass through, achieving a double-sided cleaning effect. Compared to traditional single-sided cleaning machines, this invention provides a practical double-sided simultaneous cleaning effect, eliminating the need for secondary turning of the leather for cleaning. This significantly improves the cleaning efficiency of this invention, increases the overall speed of leather processing and production, and demonstrates good practicality.

[0039] Furthermore, when it is necessary to adjust the gap between the two cleaning rollers, two operators can manually rotate the two rotating handles 10 simultaneously. When the two rotating handles 10 rotate simultaneously, they will drive the ball screw 6 to move synchronously. Since the ball screw 6 is threadedly connected to the threaded seat 7, the threaded seat 7 can move up and down when the ball screw 6 rotates. In this way, the up and down movement of the two threaded seats 7 can drive the moving cleaning roller 9 between them to move up and down. The movement of the moving cleaning roller 9 can change the gap between the two rollers. In this way, the cleaning roller of this utility model can be used to pass through leather materials of different thicknesses, ensuring the applicability of the cleaning structure. The gap between the two rollers can be dynamically adjusted according to the different thicknesses of leather materials. It has the structural applicability of dynamically adjustable roller gap, and can adapt to a wider range of leather thicknesses, effectively reducing limitations.

[0040] Furthermore, the dynamic adjustment of the gap between the rubber rollers can also adjust the pressing contact force on the leather. When the gap is reduced, the pressing force between the two rubber rollers increases, and the contact between the rubber rollers and the leather becomes tighter. When the gap between the rubber rollers increases, the pressing force between the two rubber rollers decreases. This can prevent the rubber rollers from excessively squeezing and deforming the leather. It has good structural applicability and the structure is more flexible and convenient to use.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
