Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a needle cloth needle polishing machine in a napping machine.

[Conventional technology]

In a raising machine that raises fabric by contact with a clothing roller that rotates in one direction, as the needle tips of the clothing wrapped around the outer periphery of the clothing roller become worn, the needle tips are polished using a manual polisher. I try to polish it with

As a conventional manual polishing machine, there is one in which a plurality of coaxially arranged disc-shaped grindstones are rotatably supported by a support frame. This manual polishing machine rotates the cloth roller in one direction while the drum supporting the cloth roller is stopped, and a disc-shaped grinding stone is applied to the outer circumferential surface of the cloth wound around the outer circumference of the cloth roller. The whetstone is rotated by contact with the clothing cloth, and the supporting frame of the grindstone is moved along a rail installed parallel to the clothing roller to polish the needle tip of the clothing cloth.

Here, the clothing is spirally wound around the clothing roller 21 as shown in FIG. 5, and the needles 23 of the clothing 22 are L-shaped as shown in FIG. When polishing the needle 23, it is necessary to polish the side surface and surface of the needle tip.

[Problem that the invention seeks to solve]

By the way, in the above-mentioned conventional polishing machine, when the needle tip is being polished, the axis of the cloth roller and the rotation center of the disc-shaped grindstone are parallel to each other. There is a disadvantage that the needle tip hits the surface and cannot polish the side surface of the needle tip.

Therefore, the technical object of the present invention is to provide a polishing machine capable of eliminating the above-mentioned disadvantages and polishing the side surface and surface of the needle tip.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention has a disc-shaped surface polishing whetstone having a recessed cylindrical surface attached to the front part of a whetstone support frame, and a disc-shaped side polishing wheel provided on the side of the surface polishing whetstone. A grindstone is rotatably arranged so that a part of its outer periphery protrudes forward from the cylindrical surface, and the side surface grindstone is inclined in accordance with the winding angle of the clothing wrapped around the roller. That's what I did.

[Operation] When the grindstone support frame is placed on a rail installed parallel to the clothed roller and the whetstone support frame is pressed against the outer peripheral surface of the clothed roller, the cylindrical surface of the surface polishing whetstone touches the needle of the clothed roller. A part of the outer periphery of the side polishing grindstone, which is in contact with the tip surface and is supported in an inclined manner, fits between the needles of the clothing.

Therefore, by moving the grindstone support frame in the axial direction of the cloth roller while pressing it against the outer peripheral surface of the grindstone roller, the surface polishing grindstone that comes into contact with the surface of the needle tip can polish the needle tip. The side surface of the needle can be polished by a side polishing grindstone inserted between the needle and the needle.
