  Hereinafter, the present invention will be further described with reference to the drawings.

  Hereinafter, the present invention will be described in more detail with reference to the drawings and embodiments for practicing the present invention in order to clarify the objects, technical solutions, and advantages of the present invention. However, the protection scope of the present invention is not limited to any form of the embodiment.

The basic structure, grinding method and principle of the polishing apparatus in the present invention have already been described and explained in a part of the summary of the present invention. In the following, in combination with the figures, a preferred embodiment of two different schemes will be described in detail as to how to process the ends of the hair into hemispheres.
Example 1
As shown in FIGS. 1 to 3, since it is not possible to pinch and process a single extra fine hair, many of the haired thin pieces are connected to the fixed shaft in advance to increase the efficiency and solve the problem. Thereby, the flakes with skewered hair to be processed are formed. The entire skewer-like flakes are mounted on the polishing apparatus of the present invention and processed to achieve polishing on a single bristle tip.

  A pair of sliding modules 1 is provided on each of the left and right ends of the grinding wheel 5. The sliding module 1 is a fixed base 101, a slide base 102, a slide rail 103, and a traction module for pulling off one end of the fixed base 101. 104. The fixed shaft 401 of the skewer-shaped thin piece 4 to be processed is held by the fixed base 101, and when it is necessary to remove the fixed shaft 401, a similar pull-out operation is adopted. By installing two sets of the sliding modules 1, two skewer-shaped thin pieces 4 can be processed at the same time, and the efficiency is further improved.

  In FIGS. 1 to 3, a first motor 301 is provided below a belt 204 connected to a drive shaft 201, the drive shaft 201 rotates, and a driven shaft 202 is moved by a belt pulley 205 and a belt 204, and the belt 204 is in close contact. The slide table 102 is moved on a slide rail 103. In the present embodiment, the skewer-shaped flakes 4 on the fixed base 101 pass before and after the two pre-grinding wheels 501 and the post-grinding wheels 502 that rotate in opposite directions at a constant speed. The grinding wheel before and after the grinding is a metal alloy grinding wheel, which has a spiral pattern 6 on the surface of the grinding wheel 5, thereby grinding the bristle tip. When the skewer-like haired flakes 4 pass through the grinding wheel 5, the tip of the hairy flakes 402 is processed and ground, and at the same time, the hairy flakes 402 rotate. Since the rotation direction of the pre-grinding wheel 501 is opposite to that of the post-grinding wheel 502, both surfaces of the bristle end on the bristle flakes 402 can be processed. For example, the rotation direction when the hairy flake 402 is ground by the pre-grinding wheel 501 is upward, and at this time, the lower side of the end of the hair is ground, while the hairy flake 402 moves the wheel 502 after grinding. When the time elapses, the rotation direction is downward, and at this time, the upper side of the bristle end is ground. In this way, under the driving of the sliding module 1, the processing with the two grinding wheels 5 and the grinding process the hairy thin piece 402 twice, thus processing the two upper and lower positions of the tip end of the hair respectively. Finally, a ball head-shaped end is formed.

  If the bristle tip polishing requirement is higher, the first motor 301 can be controlled to rotate in the opposite direction to return the sliding module 1 to the first path. That is, by repeating the above processing and polishing once, a very good polishing effect can be achieved. This situation is applicable to the processing of some extra-fine, soft hairs, with no blind spots for polishing the hair tips. In addition, the rotation speed of the first motor 301, the second motor 302, and the third motor 303 is adjustable, so that hairs of different diameters and lengths can be adjusted. Controlling the speed of relative movement between the before and after wheels and the skewer flakes ensures that the grinding effect is most favorable.

Example 2
The difference between the present embodiment and the first embodiment is as follows. As shown in FIG. 4, the number of the grinding wheels 5 is one, which is controlled by the second motor 302, and the skewer-shaped flakes 4 on the fixed base 101 pass through only one grinding wheel 5 rotating at a constant speed. . When the skewer-like thin piece 4 moves from one end to the other end by the driving of the sliding module 1, the grinding wheel 5 can only grind one side of the bristle end of the thin piece 402 with hair. For this reason, the measure used is to control the second motor 302 to rotate the grinding wheel 5 in reverse when the skewer haired flakes 4 return to the first path, and also to grind the other end of the bristle end. It can be guaranteed that it can be processed. With such a single reciprocation, the bristles eventually form a ball head-like end.

  Hereinafter, the locus of the contact point between the bristle end surface and the spiral grinding surface in the grinding process will be described. A coordinate system is constructed by setting the moving direction of the skewer-shaped thin piece 4 as the X axis and the axial direction of the grinding wheel 5 as the Z axis, as shown in FIG. FIG. 6 is a schematic view in the axial direction of the flakes with skewer hairs. In the enlarged portion, both surfaces of the spiral pattern 6 are a spiral grinding surface A601 and a spiral grinding surface B602, respectively. Has a spiral transition surface C603. At the same time as the hairy flakes 402 rotate to realize the grinding of the hairs 403 in the Z and Y axis directions, the hairs 403 form a trajectory along the direction of the spiral involute on the surface of the grinding wheel 5. As shown in FIG. The end of the bristles 403 realizes grinding in the X and Y-axis directions under the action of the spiral grinding surface, and finally realizes processing of the bristle tip into a spherical shape.

Operating principle Each of the hairy slices of the skewer-like hairy slice can freely rotate independently on a fixed axis. When the grinding wheel rotates and comes into contact with the hairy flakes, the transmission of the force of the spiral grinding surface causes the hairy flakes to rotate. The bristles on the bristle flakes are flexible, the relative movement between the ends of the bristles and the helical grinding surface has a speed difference, and the grinding wheel grinds the ends of the bristles. It is necessary to explain that the point at which the end of the bristle contacts the helical ground surface is not fixed and does not change. With the drive rotation of the grinding wheel and the driven rotation of the bristle flakes, the trajectory of the point where the end of the bristle comes into contact with the spiral grinding surface is a spiral involute when viewed from the overhead direction of the axis of the grinding wheel. Just by the gradual change of the contact point of the bristle end, the bristle end can finally be machined into a hemisphere.

  To ensure that sharp, dull, fine burrs at the ends of the bristles in the bristle flakes can be ground with high efficiency, the present invention uses The ends of the hairs of the flakes are ground. The unique design of the helical grinding surface can achieve an excellent effect of polishing the bristle tip in the shape of a ball head, and the bristle on the bristle flakes hardly leaks. Both artificial grinding and mechanical grinding in existing technologies, regardless of efficiency or effectiveness, are significantly improved.

  The operation of the present invention is simple, practical and convenient, enhances the polishing efficiency, and achieves a uniform and blind-free polishing effect.

  The embodiments for carrying out the invention described above explain the technical solution of the present invention and do not limit the invention. Any other modification or replacement made by a person skilled in the art to the technical solution of the present invention should be included in the scope of the claims of the present invention unless departing from the spirit and scope of the technical solution of the present invention. is there.
