Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rail mounting bracket for flat needle polishing provided on a carding machine, and particularly to a needle polishing device that performs polishing while moving a flat needle polishing member along a guide rail provided on the carding machine. The guide rail is supported and the flat bar is reliably held in position.

The combing action of fibers in a flat carding machine is mainly performed by the tips of the clothing needles and blade-shaped wires provided on the circumference of the cylinder, and the tips of the clothing needles and blade-shaped members provided on the flat bar. The tips of each are sharply pointed. Generally speaking, clothing needles are often used as attachments to the flat bar.

However, in order to continue good combing action, it is necessary to keep these tips sharp at all times, and in particular, the flat needle tips move slightly against the cylinder side blade member that rotates at high speed, but they do not move very often. It is necessary to arrange them so that they are almost fixed, and to maintain an extremely small gap. For this reason, the tips of the flat needles are easily worn out, so the needles are polished.For this polishing, a needle polishing device is attached to the carding machine and an on-machine polishing means is applied to the idle side flat during operation.
There is an under-board polishing method in which the flats are removed from the carding machine and a special needle polishing device is used.The former type of on-machine polishing uses a hose roller (traverse foil) or a long roller, and the flats are removed from the carding machine. Grinding brackets are provided for locating these needle polishing devices. Also, long rollers or sometimes grinding wheels are used for the latter type of polishing needles, but these polishing needles are used to make the height of the needles uniform and to make the tips of the needles sharp.

On the other hand, in terms of the level and accuracy of polishing, it is said that under-the-board polishing is superior, and therefore, under-the-stand polishing is of course performed not only when replacing flat needle cloths, but also periodically. However, when polishing needles under the stand, the machine must be stopped and at least three people are required to attach and remove the flat, which does not contribute to increased production and cost reduction. Based on these, the present inventor has developed the conventional on-machine polishing method.
We have developed a method for polishing needles that can be done with precision comparable to that of polishing needles by placing the needle on a stand. The method involves improving the grinding bracket provided for on-machine polishing needles, attaching a guide rail to it, and reciprocating a grinding device equipped with a grinding wheel and a thin-blade grinder along the guide rail. In particular, the tips of the needles were sharpened to restore the combing action.

However, when using such a needle polishing method, the flat bar holding means provided in the conventional grinding bracket holds the end of the flat bar to the plate cam between the bottom surface of the slide box and the top surface of the horn bracket. The flat bar is configured to allow movement while being clamped by a lifter connected to a weight lever, and its adjustment and maintenance requires special skills and great care. If these are not sufficient, even if the bevel is polished, the surface will not be uniform, and it may even become difficult to maintain the gap with the cylinder.

Therefore, in the present invention, when adopting the above-mentioned polishing needle method, the grinding bracket is improved, and the work in process of the carding machine is interrupted when the polishing needles are hit.
Only the machine mounting flat is intermittently driven by a specially provided drive device, and a part of the carding machine is used as a polishing device below the table, improving the accuracy of polishing needles and sharpening the tips of the needles. It is an object of the present invention to provide a grinding bracket that further improves the grinding performance. However, this kind of invention is
A grinding bracket is provided at each cylinder bend so that the distance from the cylinder axis can be adjusted, a guide rail mounting seat is formed at the top of the bracket, a relatively long flat bar rear guide rail member is provided inside, and At the upper part of the guide rail member, a clearance is formed for the end of the flat bar to pass through, and a flat bar belly surface position regulating block is attached, and a flat polishing needle position is installed approximately in the center of the block.
