[0001] The utility model relates to the technical field of steel ball processing equipment, in particular to a steel ball wiping device. Background Art

[0002] The steel ball production process includes grinding, cleaning, appearance inspection, spraying of rust inhibitors, counting and packaging, etc.; since the abrasive used in the steel ball grinding process contains a large number of polar groups and has strong adhesion properties, it adheres to the surface of the steel ball to form a scale layer. The scale layer is firmly adsorbed and the composition of the scale layer is complex. It not only contains polyvinyl alcohol, stearic acid and metal soaps, but also contains a large amount of abrasive chips, so it needs to be cleaned.

[0003] After cleaning, the steel ball surface needs to be wiped dry to allow for subsequent application of various protective fluids, such as those for rust prevention or lubrication. A hot air blower can quickly dry the metal surface, but the high-temperature airflow can cause thermal stress on the metal surface, especially for temperature-sensitive or easily deformed metals, which can cause surface deformation or increased internal stress. The steel ball needs to be wiped around the surface, typically manually, but this process can easily miss areas and is inefficient. Utility Model Content

[0022] like Figure 1 、 2 As shown, an embodiment of the utility model proposes a steel ball wiping device, including a conveying assembly, a lower fixed assembly and an upper wiping assembly, wherein the lower fixed assembly is used to evenly place the steel balls and keep the steel balls in a fixed position during rotation, the upper wiping assembly is arranged above the lower fixed assembly and can move downward, and the upper wiping assembly is used to drive the steel balls to rotate and wipe at the same time; the conveying assembly is fixedly arranged on one side of the lower fixed assembly, and the conveying assembly can be rotated to the top or outside of the lower fixed assembly, and the conveying assembly is used to disperse the steel balls on the lower fixed assembly.

[0023] The conveying assembly includes a base 5, a hopper 9, a first connecting rod 6, a second connecting rod 8, a first motor 22, a second motor 24, a connector 7, a controller, and a conveying unit. The base 5 is fixedly mounted on one side of the lower fixed assembly, and the hopper 9 is fixedly mounted above the base 5. The first connecting rod 6 is horizontally mounted, with a connecting ring 19 at one end. The connecting ring 19 is rotatably connected to the base 5, and the rotation trajectory of the other end of the first connecting rod 6 passes through the center of the lower fixed assembly. A rotating rod 21 is fixedly connected to the side of the connecting ring 19. A staff member pushes the rotating rod 21 to rotate the connecting ring 19, thereby moving the end of the first connecting rod 6 directly above or outside the lower fixed assembly. The connector 7 is rotatably connected to the bottom of the end of the first connecting rod 6 away from the base 5. The second connecting rod 8 is horizontally mounted and slidably connected to the connector 7. The connector 7 has sliding holes extending left and right, and the second connecting rod 8 slides into the sliding holes.

The transmission unit is used to transmit the steel ball along the first connecting rod 6 to the end of the second connecting rod 8. The controller is electrically connected to the first motor 22 and the second motor 24.

[0024] In this embodiment, the first motor 22 is fixedly arranged at the end of the first connecting rod 6, and the output shaft of the first motor 22 is provided with a first gear 23. The top of the connector 7 is a cylindrical structure, and the top of the cylinder is provided with a limit ring.

The second motor 24 is fixedly connected to the connector 7, and a second gear 25 is fixedly provided on the second motor 24. The bottom of the second connecting rod 8 is provided with a bar tooth. The second motor 24 is located at the bottom of the sliding hole, and the second gear 25 is meshed with the bar groove. When the upper wiping assembly and the lower fixed assembly are in contact, the staff pushes the rotating rod 21 to drive the connecting ring 19 to rotate, so that the first connecting rod 6 rotates to the side of the lower fixed assembly. The first motor 22 causes the connector 7 to rotate, and the second motor 24 causes the distance from the end of the second connecting rod 8 to the center of the placement plate to change.

[0025] like Figure 1 、 2As shown, preferably, the lower fixed assembly includes a placement plate 1, a first telescopic rod 2, a second telescopic rod 3 and a plurality of push rods 4. The placement plate 1 is circular, and the hole positions 17 on the placement plate 1 are arranged in a spiral shape. The fixed sections at the bottom of the first telescopic rod 2 and the second telescopic rod 3 are fixedly arranged, and the center and edge of the bottom surface of the placement plate 1 are hinged to the movable sections at the tops of the first telescopic rod 2 and the second telescopic rod 3, respectively. Several push rods 4 corresponding to the hole positions 17 are fixedly arranged below the placement plate 1, and the diameter of the push rods 4 is smaller than the hole positions 17. The bottom of the push rods 4 is fixedly connected to a fixed bracket. A first annular groove 16 is provided on the top surface of the placement plate 1, and a notch 18 is provided on the first annular groove 16. The notch 18 is located above the second telescopic rod 3. When wiping the steel ball, the conveying group places the steel ball on each circular hole. After wiping is complete, the first and second telescopic rods 2 and 3 are retracted synchronously, lowering the placement plate 1 so that it is flush with the top of the top rod 4. The second telescopic rod 2 then retracts further, tilting the placement plate 1. The steel balls roll into the first annular groove 16 and are removed through the notch 18. A transfer device or container can be provided below the notch 18 to move the steel balls to the next process. The conveyor assembly is used to place the steel balls one by one onto the holes 17.

[0026] like Figure 1 、 3 As shown in Figures 4 and 5, the conveying unit preferably includes a first connecting rod 6 having a first channel 26 inclined at its top. The first channel 26 is inclined downward at its end near the connector 7. A second annular groove 32 is provided on the top surface of the connecting ring 19. The bottom surface of the second annular groove 32 is inclined, and the lowest point of the second annular groove 32 is connected to the first channel 26. The discharge hole of the hopper 9 extends above the second annular groove 32. A third channel 28 is provided on the second connecting rod 8. The bottom surface of the third channel 28 is inclined, and a discharge port is provided at the downward end of the third channel 28. A second channel 27 is vertically provided on the connector 7 to connect the first channel 26 and the third channel 28. A first control switch 29 is provided on the third channel 28 to control the passage of steel balls. In this embodiment, the first connecting rod 6 and the second connecting rod 8 are both rectangular parallelepipeds. When the first connecting rod 6 and the second connecting rod 8 move so that the ends of the second connecting rod 8 move one by one above the hole 17, the first control switch 29 controls the steel balls to fall one by one.

[0027] like Figure 1 、 Figure 5As shown, as preferably, the upper wiping assembly includes a fourth motor 15, a fixed disk 14, a support frame 10, a sun gear 11, a planetary gear 13, a gear ring 33 and a third telescopic rod 12, the sun gear 11 is arranged directly above the placement plate 1, the top of the sun gear 11 is rotatably connected to the support frame 10, the gear ring 33 and the sun gear 11 are coaxial and sleeved on the outside of the sun gear 11, the gear ring 33 is fixedly connected to the support frame 10, the planetary gear 13 is arranged between the gear ring 33 and the sun gear 11 and meshes with the two at the same time, the fourth motor 15 is fixedly connected to the support frame 10 and is used to drive the sun gear 10 to rotate, the fixed disk 14 is horizontally arranged directly below the planetary gear 13, the third telescopic rod 12 is vertically arranged, the fixed section of the third telescopic rod 12 is fixedly connected to the center of the planetary gear 13, the movable section of the third telescopic rod 12 is rotatably connected to the center of the fixed disk 14, and the wiping layer is fixedly arranged on the bottom surface of the fixed disk 14. The planetary gear structure of the fifth motor 15 causes the third telescopic rod 12, connected to the planetary gear, to rotate while orbiting. This causes the fixed plate at the bottom of the third telescopic rod 12 to simultaneously orbit and rotate. As a result, frictional contact between the wiping layer and the steel ball drives the steel ball to rotate, ensuring that all areas of the steel ball are in contact with the wiping layer. In this embodiment, the tops of the sun gear 11 and planetary gears 13 engage with the bracket to prevent vertical movement of the sun gear 11 and planetary gears 13.

[0028] Preferably, the wiping layer and the fixed plate 14 are detachably connected, allowing for quick replacement if the wiping layer absorbs excessive water or becomes damaged by friction. In this embodiment, the wiping layer comprises a thick, water-washable cotton pad. The water-washable cotton pad is compressed when in contact with the steel ball, creating sufficient friction between the steel ball and the water-washable cotton pad, ensuring that the steel ball rotates as the wiping layer moves.

[0029] Preferably, the placement plate 1 is made of plastic. When the steel ball is placed on the placement plate 1 and rotated by friction, the plastic placement plate 1 will not cause scratches to the steel ball.

[0030] Preferably, a second control switch 30 is provided at the bottom of the hopper 9. The second control switch 30 prevents too many steel balls from being on the conveying component at the same time. The total amount of steel balls on the conveying component will cause the conveying component structure to deform after long-term use.

[0031] like Figure 3 As shown, preferably, a fourth telescopic rod 31 is vertically mounted at the bottom of the connector 7. The fixed section at the top of the fourth telescopic rod 31 is rotatably connected to the connector 7, and a contact block is disposed at the bottom of the fourth telescopic rod 31. When the first connecting rod 6 rotates so that the connector 7 is located at the bottom of the placement plate 1, the fourth telescopic rod 31 extends so that the contact block contacts the center of the placement plate 1, providing support and improving the stability of the structure.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
