example 1:

as shown in fig. 1-3, because the single superfine wool can not be clamped for processing, in order to improve efficiency and solve the problem, a plurality of the wool sheets are strung on the fixed shaft in advance to form a wool sheet string to be processed, and the whole wool sheet string is provided with the sanding device of the invention for processing, thereby achieving the purpose of grinding the end of the single wool.

In fig. 1-3, a first motor 301 is arranged below a belt 204 connected with a driving shaft 201, the driving shaft 201 rotates to drive a driven shaft 202 through a belt pulley 205 and the belt 204, the belt 204 drives a closely attached sliding seat 102 to move on a sliding rail 103, in this embodiment, a hair string 4 on a fixed seat 101 sequentially passes through two grinding front wheels 501 and grinding rear wheels 502 which rotate at uniform speed and in opposite directions, the grinding front wheels and the grinding rear wheels are grinding wheels of metal alloy, and spiral threads 6 are formed on the surfaces of the grinding wheels 5, so that the hair ends are ground. When the wool top string 4 passes through the grinding wheel 5, the end of the wool top 402 is processed and ground, and meanwhile, the wool top 402 is driven to rotate, and the rotating direction of the grinding front wheel 501 is opposite to that of the grinding rear wheel 502, so that the end of the wool top on the wool top 402 can be processed on both sides, for example, the rotating direction of the wool top 402 driven by the grinding front wheel 501 is upward, at this time, the lower side of the end of the wool top is ground, and the upper side of the end of the wool top 402 is driven to rotate again when passing through the grinding rear wheel 502, at this time, the upper side of the end of the wool top is ground and processed twice, which is equivalent to that of the wool top 402 driven by the sliding component 1, through the processing and grinding of the two grinding wheels 5, so that the upper position and the lower position of the end of the wool top are processed, and finally, the end of the ball head is formed.

Example 2:

the difference between this embodiment and embodiment 1 is that, as shown in fig. 4, the number of grinding wheels 5 is one and controlled by the second motor 302, the wool string 4 on the fixing seat 101 only passes through one grinding wheel 5 rotating at a constant speed, when the wool string 4 is driven by the sliding component 1 to move from one end to the other end, the grinding wheel 5 only grinds one side of the end of the wool on the wool sheet 402, therefore, measures are taken that when the wool string 4 returns in the original path, the second motor 302 controls the grinding wheel 5 to rotate reversely, so that the other side of the end of the wool can be ground, and thus, the wool forms a ball-shaped end finally through one round trip movement.

In the following description, the moving direction of the bristle string 4 is taken as the X axis, the axial direction of the grinding wheel 5 is taken as the Z axis to establish a coordinate system, as shown in fig. 5, fig. 6 is a schematic diagram of the axial direction of the bristle string, in the enlarged part, two sides of the spiral thread 6 are respectively a spiral grinding surface A601 and a spiral grinding surface B602, a spiral transition surface C603 is further arranged between the spiral grinding surfaces A and B, the bristle 402 rotates the bristle 403 to realize Z, Y axial grinding, the bristle 403 forms a track along the direction of a spiral involute on the surface of the grinding wheel 5, as shown in fig. 7, the end of the bristle 403 realizes the X, Y axial grinding under the action of the spiral grinding surface, and finally, the bristle head is processed into a sphere.
