Detailed implementation manners

[0041] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, in the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present utility model. However, those skilled in the art should clearly understand that the present utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present utility model.

[0042] Combined with the specification appendix Figure 1 To appendix Figure 6 As can be seen, a cleaning and polishing device for leather production provided by the present utility model mainly includes the following parts or components: an operation box 10, a first polishing roller 121, a second polishing roller 122, a dust removal box 13, a spray pipe 14, and a loading box 15.

[0043] In the present utility model, feeding ports 101 and discharging ports 102 are arranged on both sides of the operation box 10. Inside the operation box 10 between the discharging port 102 and the feeding port 101, two rotatable guide rollers 11 for guiding materials are arranged; the first polishing roller 121 and the second polishing roller 122 are arranged in parallel on the support frame and are located above and below the material. The two polishing rollers rotate under the drive of the drive assembly 40; the dust removal box 13 is arranged on one side of the operation box 10, and the dust inlet on it is connected to two dust collection covers 132 on one side of the two polishing rollers respectively through a connecting pipe 131; the two spray pipes 14 are arranged in parallel inside the dust removal box 13 and drive the two spray pipes 14 to swing under the drive of the swing assembly 30. Two spray heads 141 are respectively arranged on the two spray pipes 14; the loading box 15 is used for loading filter plates. The loading box 15 is horizontally arranged below the dust inlet, and through holes 151 are arranged at the bottom of the loading box 15. The loading box 15 extends out or retracts into the dust removal box 13 under the drive of the telescopic assembly 20. The water outlet pipe 133 below the loading box 15 is connected to the end of the spray pipe 14 through a rotary joint 142.

[0044] During operation, materials enter the operation box 10 from the feed inlet 101 and exit from the discharge outlet 102. The guide roller 11 guides the materials, and the materials are polished by the first polishing roller 121 and the second polishing roller 122, which can effectively polish both sides of the materials simultaneously. During the polishing process, the generated dust is sent to the dust removal box 13 through two dust collection covers 132 and the connecting pipe 131. The two spray pipes 14 swing under the drive of the swing assembly 30, and the nozzles 141 on the two spray pipes 14 spray water on the dust entering the dust removal box 13. The water combines with the dust to form sewage. After the sewage is filtered by the filter plate, the filtered water falls to the bottom of the dust removal box 13 through the through holes 151 on the filter plate and the receiving box 15, and then is sent into the two spray pipes 14 through the water outlet pipe 133, realizing the recycling of water. When there are too many impurities on the filter plate, the telescopic assembly 20 drives the receiving box 15 to extend or retract into the dust removal box 13, facilitating the replacement of the filter plate, effectively treating dust, and improving the quality of the working environment.

[0045] Wherein, two notches are provided on both sides of the receiving box 15 for facilitating the taking of the filter plate.

[0046] As an embodiment, in combination with the attached drawings of the specification Figure 2 It can be seen that the two lower ends of the receiving box 15 are slidably connected to the slide rails 134 on both sides of the dust removal box 13. The telescopic assembly 20 includes a first rotating shaft 21, which is horizontally arranged in the dust removal box 13 and rotates under the drive of a first motor 22; a first connecting rod 23 is arranged in the dust removal box 13, and its lower end is connected to the end of the first rotating shaft 21. The first guiding column 231 at the upper end of the first connecting rod 23 is slidably connected to the first long slot hole 152 at the lower end of the receiving box 15.

[0047] The first motor 22 drives the first rotating shaft 21 to rotate forward and backward alternately. The first rotating shaft 21 drives the first connecting rod 23 to swing. The first guiding column 231 on the first connecting rod 23 cooperates with the first long slot hole 152, causing the receiving box 15 to slide on the slide rail 134, so that the receiving box 15 extends or retracts into the dust removal box 13, effectively facilitating the replacement of the filter plate.

[0048] Wherein, the first motor 22 is a forward and reverse motor.

[0049] As an embodiment, in combination with the attached drawings of the specification Figure 3 It can be seen that the swing assembly 30 includes a mounting frame 31 arranged in the dust removal box 13; a first rack 32 is arranged above the inner side of the mounting frame 31 and meshes with a first gear 33 arranged at the end of one of the spray pipes 14; a second rack 34 is arranged below the inner side of the mounting frame 31 and meshes with a second gear 35 arranged at the end of the other spray pipe 14; a semi-circular gear 36 is arranged between the two racks and alternately meshes with the two racks under the drive of a second motor 37.

[0050] The second motor 37 is installed on the dust removal box 13. The output end of the second motor 37 is key-connected to the semi-circular gear 36. The semi-circular gear 36 meshes with the first rack 32 and the second rack 34 alternately. The first rack 32 and the second rack 34 respectively mesh with the first gear 33 and the second gear 35. The first gear 33 and the second gear 35 can respectively drive the spray pipes 14 connected thereto to swing.

[0051] In this embodiment, as can be seen from the attached drawings of the specification Figure 3 The swing assembly further includes a guiding assembly. The guiding assembly includes a plurality of rollers 38. The plurality of rollers 38 are respectively arranged on the dust removal box 13 on the upper and lower sides of the mounting frame 31. An annular groove 381 is formed on the circumferential surface of each roller 38. The annular groove 381 is adapted to the mounting frame 31. The annular groove 381 catches the outside of the mounting frame 31, which can limit the displacement of the mounting frame 31 in the vertical direction. The rollers 38 can be made of nylon material, which is light in weight, stable in performance and convenient to replace.

[0052] As an embodiment, as can be seen from the attached drawings of the specification Figure 4 to the attached Figure 6 drawings, the first grinding roller 121 is lifted and lowered under the drive of the lifting assembly 50, and the driving assembly 40 can always drive the first grinding roller 121 to rotate during the lifting process of the first grinding roller 121. The driving assembly 40 includes a second rotating shaft 42, which is vertically arranged in the operation box 10 and rotates under the drive of the third motor 41. The first bevel gear 421 on the second rotating shaft 42 meshes with the second bevel gear 123 on the second grinding roller 122. A fourth bevel gear 43 is arranged on the second rotating shaft 42. The fourth bevel gear 43 is connected to the lifting assembly 50. When the lifting assembly 50 drives the fourth bevel gear 43 to lift and lower along the axial direction of the second rotating shaft 42, the fourth bevel gear 43 always meshes with the third bevel gear 44 on the first grinding roller 121.

[0053] The lifting assembly 50 includes a sliding seat 51, which is slidably arranged on the support frame. The first grinding roller 121 is arranged on the sliding seat 51. A fourth bevel gear 43 is rotatably connected to the sliding seat 51. A guiding key 511 is arranged on the fourth bevel gear 43. The guiding key 511 is adapted to the guiding groove arranged along the axial direction of the second rotating shaft 42 on the second rotating shaft 42. The first end of the screw 52 is rotatably connected to the sliding seat 51, and the second end is lifted and lowered under the drive of the rotating assembly.

[0054] The third motor 41 drives the second rotating shaft 42 to rotate. The first bevel gear 421 on the second rotating shaft 42 drives the second grinding roller 122 to rotate through cooperation with the second bevel gear 123. The second rotating shaft 42 drives the first grinding roller 121 to rotate through the meshing of the fourth bevel gear 43 and the third bevel gear 44. When the thickness of the leather changes, the rotating assembly drives the slide block 51 to move up and down. The slide block 51 drives the first grinding roller 121 and the third bevel gear 44 to move up and down synchronously. Since the guiding key 511 on the first grinding roller 121 is adapted to the guiding groove arranged along the axial direction of the second rotating shaft 42 on the second rotating shaft 42, the fourth bevel gear 43 can always drive the third bevel gear 44 to rotate, causing the first grinding roller 121 to rotate. Thus, when the thickness of the leather changes, the first grinding roller 121 can be adjusted according to the actual situation.

[0055] In this embodiment, as can be seen from the attached drawings of the specification Figure 6 The rotating assembly includes a third gear 53 rotatably arranged on the operation box 10. The second end of the screw rod 52 penetrates through the top of the operation box 10 and is threadedly connected to and penetrates through the third gear 53. A fourth motor 54 is arranged on the operation box 10, and a fourth gear 55 is arranged at its power output end. The fourth gear 55 meshes with the third gear 53. The fourth motor 54 drives the fourth gear 55 to rotate, the fourth gear 55 drives the third gear 53 to rotate, and the third gear 53 drives the screw rod 52 to move up and down.

[0056] Among them, the fourth motor 54 is a forward and reverse rotation motor.
