Abstract

The present invention relates to the technical field of leather cleaning components, and specifically relates to a leather surface dirt cleaning component, which includes a base and two basic blocks. A control component and a cleaning brush component are arranged on the tops of the two basic blocks. Adjusting components with the same structure are arranged on the outer walls of the two basic blocks on the sides close to each other. The adjusting component includes a protective part, and the protective part is fixedly connected to the outer wall of the basic block. By operating the control component, the opening of two electric push rods I is controlled, the height of the double-sided rack is increased, and thus the position of the support roller shaft at the middle position is raised. At the same time, the height of the two single-sided racks is decreased, and the heights of the other two support roller shafts also decrease accordingly. The angle at the top of the leather becomes smaller and sharper, so that the grooves at the corresponding position of the leather are exposed, and the dirt hidden in the grooves is thus revealed, which is conducive to the cleaning brush component to deeply clean it and improve the cleaning effect on the leather.

Description

Technical Field

[0001] The present invention belongs to the technical field of leather cleaning components, and particularly relates to a leather surface dirt cleaning component. Background Art

[0002] Leather is the animal skin that has been denatured and is not easily decayed through physical and chemical processes such as hair removal and tanning. Leather is composed of natural protein fibers tightly woven in three-dimensional space, with a special grain layer on its surface, having natural grain patterns and luster, and a comfortable handfeel.

[0003] After the leather is processed, a large amount of dust will be adsorbed on its surface. Cleaning the dirt on the leather surface can maintain the beauty of the leather, extend its service life, and prevent the leather from being damaged or deteriorated due to the penetration of dirt.

[0004] As stated in the Chinese patent with the publication number: CN218309516U, it proposes a leather surface cleaning device. Through the setting of the cleaning component, the biaxial motor drives the rotating shaft to rotate. Under the rotation of the rotating shaft, the brush disk brushes off the debris and impurities on the surface of the material. While the rotating shaft rotates, the gear rotates, causing the gear to drive the biaxial motor to move linearly to one side, thereby moving the water tank, and then the water tank drives to clean the surface of the material in all directions. Through the cleaning effect of the cleaning component, the surface of the material can be comprehensively cleaned, while ensuring the cleaning effect on the surface of the material and improving the cleaning quality.

[0005] Due to the characteristics of leather, there may be grooves on its surface, and there is a possibility of hiding dirt in these grooves. However, during the cleaning process of the above device, the brush disk sweeps across the leather, and there is a possibility that it is not easy to remove the dirt hidden in the grooves, and the cleaning effect still needs to be improved. For this reason, we propose a leather surface dirt cleaning component. Summary of the Invention

An electric push rod two 26 is arranged on the outer wall of one side of each top block 21. One end of each of the two first connecting rods 5 is fixedly connected with a cross block 17. The cross block 17 is fixedly connected with the first pressing block 18. An inner groove is formed inside the base block 2. The connecting block 4, the two first connecting rods 5 and the cross block 17 are all slidably connected to the inside of the inner groove. Electric push rods one 6 are arranged at the bottom ends of the inner walls of the inner groove. One end of the output shafts of the two electric push rods one 6 is respectively fixedly connected with the bottom ends of the two first connecting rods 5. And the output shaft ends of the electric push rods one 6 are located at the middle positions between the connecting block 4 and the cross block 17. On the outer walls of the two mutually adjacent sides of the two base blocks 2, two top blocks 21 which are mutually far away and symmetrically distributed are fixedly connected. A smooth rod 20 and a reinforcing rod 23 are fixedly connected to the bottom end of the top block 21. The second pressing block 22 is slidably connected to the outer wall of the reinforcing rod 23. The first pressing block 18 is slidably connected to the outer wall of the smooth rod 20. The tops of the first pressing block 18 and the second pressing block 22 are both movably connected to the bottom end of the top block 21. Rubber pads 19 are fixedly connected to the bottom ends of the first pressing block 18 and the second pressing block 22. Vertical grooves are formed on the outer walls of the mutually adjacent sides of the first pressing block 18 and the second pressing block 22. Tooth plates are fixedly connected to the inner walls of the two vertical grooves. The same tooth column 25 is meshed between the two tooth plates. The two ends of the tooth column 25 are respectively rotatably connected with a stabilizing plate 24. The tops of the two stabilizing plates 24 are fixedly connected to the bottom end of the top block 21. The first pressing block 18 and the second pressing block 22 are both in sliding connection with the two stabilizing plates 24. That is, the arrangement of the two stabilizing plates 24 has no influence on the displacement process of the first pressing block 18 and the second pressing block 22.

[0034] It should be noted here that: "the three supporting rollers are rotatably connected between the two double-sided racks 10 and the two groups of single-sided racks 13", and the meaning of group here is: the two single-sided racks 13 at the same setting position in the two protective members 3 are regarded as a group, the control component belongs to the existing mature technology, it can transmit electrical signals to each electric push rod 1 6 and electric push rod 2 26, so as to drive them to work, the cleaning effect of the cleaning brush assembly is consistent with the effect of the cleaning assembly in the comparative document mentioned in the background technology, and the cleaning effect of the cleaning brush assembly in the comparative document mentioned in the background technology is consistent with the cleaning effect of the cleaning brush ... Figure 2 and 7 This state corresponds to the initial state of the device of the present invention, that is, the state in which the leather has been installed but the operation has not started. In this state, the angle formed by the three support rollers is set to α, and α is an obtuse angle. When the cleaning operation starts, the cleaning brush assembly will clean the surface of the leather. After cleaning for a certain period of time, the control assembly will transmit an electrical signal to each electric push rod 1 6 and electric push rod 2 26. The output shaft of the electric push rod 2 26 extends and comes into contact with the leather, and then the leather is tightly pressed, similar to fixing the leather. The output shaft of the electric push rod 1 6 extends, and under the connection of the connecting rod 1 5, the connecting block 4 and the slider 1 11, the height of the double-sided racks 10 at both ends is simultaneously increased, thereby increasing the height of the support roller located in the middle position. It will pull the leather upwards, through the gear 12 and the two single-sided racks 13, which are affected by the meshing relationship with the double-sided rack 10, the upward movement of the double-sided rack 10 is fed back to the two single-sided racks 13, and the two single-sided racks 13 are displaced obliquely downward, thereby reducing the height of the other two supporting rollers. At this time, the two rollers lose contact with the leather. Since the contact part between the top of the leather and the supporting roller in the middle position is propped up, that is, α is reduced but still remains obtuse, the groove here becomes larger, and the dirt hidden in the groove is revealed, which is more conducive to subsequent comprehensive cleaning. The pre-pressing of the electric push rod 26 is to prevent the position dislocation caused when the top of the leather is propped up. The initial state of the pressing block 18 can be referred to the attached manual. Figure 6 , the rubber pad 19 at its bottom end presses the leather surface earlier than the rubber pad 19 on the pressing block 22, but in the above process, the position of the pressing block 18 is raised together with the cross block 17, and through the tooth column 25 and the two tooth plates, the upward movement of the pressing block 18 causes the pressing block 22 to move downward. It should be noted here that: the width of the pressing block 22 is greater than that of the pressing block 18, and the position where the pressing blocks 18 and 22 produce compression is defined as the pressing point, then the downward movement of the pressing block 22 is equivalent to the position of the pressing point being closer to the middle position of the leather, then the distance between the leather and the support platform 27 is reduced, and the leather is closer to the support rollers on both sides, which is convenient for subsequent cleaning operations. In addition, the lifting of the position of the pressing block 18 makes the part originally blocked by the pressing block 18 appear, which is beneficial for the cleaning brush assembly to complete a full range of cleaning of the leather later.

[0035] Embodiment 3. Please refer to Figures 1 to 11 . On the basis of Embodiment 2, the features of the mechanisms arranged on the tops of the two support platforms 27 are completely the same. An adjusting block 30 and an adjusting plate 32 are hinged to the top of the support platform 27. Through openings 29 are formed in the outer walls on both sides of the support platform 27. A connecting rod 28 is fixedly connected to the middle position of the outer wall of the first connecting rod 5. The connecting rod 28 passes through the inside of the base block 2. Auxiliary grooves 31 with an elliptical cross-section are formed in the outer walls on both sides of the adjusting block 30. One end of the connecting rod 28 is slidably connected to the inner wall of the auxiliary groove 31. A slideway for slidably connecting with the adjusting plate 32 is formed in the top of the adjusting block 30. The length of the adjusting plate 32 is greater than that of the slideway. A rotating member 33 is fixedly connected to one end of the adjusting plate 32. A rectangular groove is formed in one end of the adjusting block 30. The inside of the rectangular groove is communicated with the slideway and the external space. Adaptation grooves 37 are formed in the inner walls on both sides of the rectangular groove. Square sliders 36 are slidably connected to the inside of the adaptation grooves 37. A compensation plate 34 is fixedly connected between the two square sliders 36. An inclined groove 35 with a through type is formed in one end of the compensation plate 34. The rotating member 33 is rotatably connected between the inner walls on both sides of the inclined groove 35.

[0036] It should be noted here that in the initial state, referring to the attached drawings of the specification Figure 9 , the top surfaces of the adjusting plate 32, the adjusting block 30 and the compensation plate 34 are flush with the support platform 27 and form a complete and regular geometric body with the support platform 27. During the process of raising the position of the first connecting rod 5, the connecting rod 28 moves together and gradually disengages from the inside of the opening 29. Through the auxiliary groove 31 formed in the outer wall of the adjusting block 30, the connecting rod 28 slides along the inside of the auxiliary groove 31, so that the adjusting block 30 flips along its hinge joint with the support platform 27. At the same time, the adjusting plate 32 also flips along its hinge joint with the support platform 27 and pushes the compensation plate 34 out of the rectangular groove. Through the above components, since the top α of the leather decreases, the gaps between the leather and the two side support rollers are filled by the adjusting block 30 and the compensation plate 34. The adjusting block 30 flips out of the support platform 27 and re-forms a contact relationship with the leather. The compensation plate 34 is pushed out of the rectangular groove by the adjusting plate 32 and the rotating member 33, and further supports the leather, which is equivalent to replacing the two side support rollers to support the leather, so as to adapt to the whole adjustment process, which is beneficial to cleaning the dirt hidden in the leather grooves, and further improves the cleaning effect.

[0037] In actual use, when the cleaning operation begins, the cleaning brush assembly will clean the surface of the leather. After cleaning for a certain period of time, the control assembly will then transmit electrical signals to each electric push rod 1 6 and electric push rod 2 26. The output shaft of the electric push rod 2 26 will extend and come into contact with the leather, and then the leather will be tightly pressed, similar to fixing the leather. The output shaft of the electric push rod 1 6 will extend, and under the connection of the connecting rod 1 5, the connecting block 4 and the slider 1 1 , the heights of the double-sided racks 10 at both ends will be simultaneously increased, thereby increasing the height of the support roller shaft in the middle position, which will pull the leather upward, and through the provided gear 12 and the two single-sided racks 13, affected by their meshing relationship with the double-sided rack 10, the upward movement of the double-sided rack 10 is fed back to the two single-sided racks 13, and the two single-sided racks 13 are displaced in an oblique downward direction, thereby reducing the height of the other two support roller shafts. At this time, the two roller shafts lose contact with the leather. Since the contact portion between the top of the leather and the support roller shaft in the middle position is propped up, that is, α is reduced but still forms an obtuse angle, then here The grooves become larger, and the dirt hidden in the grooves can be revealed, which is more conducive to subsequent comprehensive cleaning. In the process of raising the position of the connecting rod 1 5, the connecting rod 28 is displaced together and gradually disengaged from the inside of the opening 29. Through the auxiliary groove 31 opened on the outer wall of the adjusting block 30, the connecting rod 28 slides along the inside of the auxiliary groove 31, so that the adjusting block 30 is flipped along the hinge between itself and the support platform 27. At the same time, the adjusting plate 32 is also flipped along the hinge between itself and the support platform 27, and pushes the compensation plate 34 to disengage from the rectangular groove. Through the above-mentioned components, due to the reduction of the top α of the leather, the gap between the leather and the supporting rollers on both sides is filled by the adjusting block 30 and the compensation plate 34, and the adjusting block 30 is flipped out of the support platform 27 and re-contacts with the leather. The compensation plate 34 is pushed out of the rectangular groove by the adjusting plate 32 and the rotating member 33, and the leather is further supported, which is equivalent to replacing the supporting rollers on both sides to support the leather, thereby adapting to the entire adjustment process, which is conducive to cleaning the dirt hidden in the leather grooves, thereby improving the cleaning effect.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
