The above polishing wheel with repeatable flocking structure is better illustrated to better understand the concept of the polishing wheel with repeatable flocking structure.

Please refer to fig. 1, a polishing wheel 10 with a repeatable bristle planting structure realizes repeated bristle planting of the brush polishing wheel by arranging a brush turntable 100 and a plurality of brush assemblies 200, the brush assemblies 200 are flexibly connected with the brush turntable 100 to ensure that the brush assemblies 200 are not damaged when being taken down from the brush turntable 100, therefore, when the brush assemblies 200 are damaged or fall off in the using process, the bristle planting operation can be directly carried out again on the original position, the problem of reduced polishing effect after the bristles on the upper part of the brush polishing wheel are failed is solved, and the whole service life of the brush polishing wheel is prolonged.

Referring to fig. 1 and 4, the brush rotating disc 100 is connected to the polishing apparatus, and the end surface of the brush rotating disc 100 away from the polishing apparatus is provided with a plurality of planting holes 110, and a plurality of brush assemblies 200 are embedded in the plurality of planting holes 110 in a one-to-one correspondence manner, wherein the hole diameter of the planting holes 110 is smaller than the cross-sectional diameter of the brush assemblies 200, i.e. the brush holes 110 and the brush assemblies 200 are in interference fit, thereby ensuring the firm connection between the brush assemblies 200 and the brush rotating disc 100.

Referring to fig. 4, in one of the brush assemblies 200, the brush assembly 200 includes bristle bundles 210 and elastic inserts 220, the bristle bundles 210 include a central folded portion 211 and polishing portions 212 located at two sides of the central folded portion 211, specifically, the bristle bundles 210 are folded in half along a middle point thereof, the folded position is the central folded portion 211, and at this time, portions located at two ends of the folded point are the polishing portions 212. The central folded part 211 and the elastic insert 220 are both located in the hair planting hole 110, the elastic insert 220 is located between the two polishing parts 212, and the elastic insert 220 is used for providing tension to push the two polishing parts 212 to move in a direction away from the central folded part 211, so that the two polishing parts 212 are both abutted against the hole wall of the hair planting hole 110.

Wherein, the bristle bundle 210 is composed of a plurality of bristle monomers 211.

Referring to fig. 4, when the bristle bundle 210 and the elastic insert 220 are located in the implantation hole 110, the hole wall of the implantation hole 110 drives the polishing portion 212 to move toward the central folded portion 211, so as to press and deform the elastic insert 220, and at this time, the elastic insert 220 has a tendency to recover to an original state, i.e., the pressed portion expands outward and generates an elastic force to react with the polishing portion 212 contacting with the pressed portion, so that the polishing portion 212 is tightly attached to the hole wall of the implantation hole 110, thereby embedding the bristle bundle 210 and the elastic insert 220 in the implantation hole 110.

When the bristle bundle 210 is excessively worn in the using process and needs to be replaced, the bristle bundle 210 is clamped by using tweezers, and the bristle bundle 210 can be pulled out from the bristle planting hole 110 by applying pulling force, and when the bristle bundle 210 is pulled out, the elastic insert 220 is extruded and deformed again, and after the bristle bundle 210 is pulled out, the hole wall of the bristle planting hole 110 is kept complete, so that the bristle planting operation can be performed again.

The hair planting operation is as follows:

referring to fig. 2, the bristle bundle 210 is moved to the opening position of the bristle planting hole 110 and is laid in a horizontal manner, and the central folded portion 211 is overlapped with the axial line of the bristle planting hole 110;

referring to fig. 3, the elastic insert 220 is pushed by the punch to abut against the central folded part 211, and a pushing force is applied to the elastic insert 220 to move in a direction approaching the planting hole 110, at this time, the central folded part 211 of the bristle bundle 210 receives a pushing force of the elastic insert 220 in a direction facing the planting hole 110, and the two polishing parts 212 of the bristle bundle 210 receive a supporting force applied by the planting hole 110 in a direction away from the planting hole 110, so that the two polishing parts 212 are driven to be folded in half with the central folded part 211 as a center, at this time, the cross section of the bristle bundle is in a "V" shape;

referring to fig. 4, finally, the central folded portion 211 is driven by the elastic insert 220 to be inserted into the implantation hole 110 and attached to the bottom surface of the implantation hole 110, at this time, the elastic insert 220 is completely inserted into the implantation hole 110, and an expansion force is generated to abut against the hole wall of the implantation hole 110 to fix the bristle bundle 210 in the implantation hole 110, at this time, the cross section of the bristle bundle is "U" shaped.

It should be noted that, in order to prevent the damage of the tuft holes 110 during the replacement of the bristle bundles 210, the hardness of the resilient inserts 220 is lower than that of the brush rotor 100, i.e., the ability of the brush rotor 100 to maintain its original state is stronger than that of the resilient inserts 220. Therefore, when the bristle bundle 210 is inserted into or pulled out of the implantation hole 110, the elastic insert 220 deforms first, so that the abrasion amount of the bristle bundle 210 to the hole wall of the implantation hole 110 in the repeated implantation process is reduced.

In order to achieve the interference fit between the planting holes 110 and the brush assembly 200, it is necessary to ensure that the cross-sectional length of the elastic insert 220 is greater than the cross-sectional diameter of the planting holes 110, in an embodiment, the diameter of the planting holes is 6mm, the cross-sectional length of the elastic insert 220 is 6.2mm, and in another embodiment, the cross-sectional length of the elastic insert 220 is 6.5 mm.

It can be understood that, when polishing is performed, the rotation speed of the brush turntable 100 is 200-.

Further, referring to fig. 4, in order to facilitate replacement of the bristle bundles 210, the brush rotating disc 100 is provided with a plurality of demolding holes 120, and the aperture of the demolding holes 120 is smaller than that of the planting holes 110. The plurality of stripping holes 120 are communicated with the plurality of planting holes 110 in a one-to-one correspondence manner, and each stripping hole 120 is positioned on one side of the brush rotating disc 100 close to the polishing equipment, so that when the bristle bundles 210 need to be punched into the planting holes 110 and taken out, a shaft-shaped tool can be inserted into the stripping holes 120 from one side of the brush rotating disc 100 far away from the bristle bundles 210, and the bristle bundles 210 planted in the planting holes 110 and the elastic inserts 220 are pushed out together.

Referring to fig. 1, in order to improve the structural stability of the apparatus and ensure the firm connection between the brush rotating plate 100 and the polishing apparatus, the brush rotating plate 100 is provided with an inner ring fixing hole set, the inner ring fixing hole set includes a plurality of inner ring fixing holes 130, and the plurality of inner ring fixing holes 130 are circumferentially distributed around the axis of the brush rotating plate 100. The brush rotary table 100 is provided with an outer ring fixing hole group, the outer ring fixing hole group comprises a plurality of outer ring fixing holes 140, and the plurality of outer ring fixing holes 140 are distributed in a circumferential array by taking the axial lead of the brush rotary table 100 as the center.
