Manufacturing device for manufacturing polishing wheel

Abstract

The invention relates to a fabrication equipment and a fabrication method used for a polishing wheel. The fabrication equipment comprises a sewing machine and a polishing wheel driving mechanism; the driving mechanism comprises a claw; one end of the claw is connected with a small central hole of the wheel core of the polishing wheel and the other end thereof is connected with one end of a transmission rod; the other end of the transmission rod is engaged with one end of a worm wheel through a worm; a wheel tooth at the other end of the worm wheel is engaged with a rack; the rack is arrangedon a bracket which is arranged beside the sewing machine. When being fabricated, a round basic sheet raw material is fabricated and a small central hole is opened at the same time; two layers and more basic sheets are overlapped together by taking the small central hole as the center; a thread involute with equal distances of an internal layer sewing line and an external layer sewing line is sewed on the basic sheet through the sewing machine so as to obtain the sewed polishing wheel; the small central hole is then taken as the center so as to punch a comparatively large assembly hole; finally, the periphery of the polishing wheel is cut and decorated by the punched assembly hole. The invention has the advantages of low fabrication cost and high working efficiency.

technical field

[0001] The invention relates to a manufacturing device for manufacturing polishing wheels. Background technique

[0002] The common polishing wheel is to overlap the multi-layer cloth, sisal or other plant fibers cut into pieces, and then sew it into a whole through thread, etc. This kind of sewing work is mostly manual, and its efficiency is very low. Ordinary sewing machines are used to sew, but the polishing wheels sewn by ordinary sewing machines, or the distance between the inner and outer suture lines of the polishing wheels cannot be kept consistent, resulting in imbalance and large vibration of the polishing wheels during use, thus Affect the polishing effect of the product; the internal and external strength of the polishing wheel is inconsistent, and it is prone to damage during use, resulting in a relatively short life, or the center of the polishing wheel cannot be effectively stitched, resulting in the polishing wheel not being fully utilized, an...
