Description

Technical Field

[0001] The utility model relates to the technical field of rubber-impregnated cloth, in particular to a thimble fixing device for rubber-impregnated cloth winding and inserting into an axle hole. Background Art

[0002] Polyester industrial yarn is twisted and woven to obtain untreated cord fabric; the woven untreated cord fabric is treated by primary dipping, drying, drawing, secondary dipping, drying and shaping to obtain dipped cord fabric. In the cloth dropping process, the treated cord fabric is wound on a wooden shaft by a winder.

[0003] In order to achieve the connection between the wooden shaft and the winder, it is usually necessary to use a pin to fix the wooden shaft. When using a pin to fix the wooden shaft, the pin needs to be in close contact with the wooden shaft. After long-term use, the pin is easily damaged, and the pin is usually fixed to the equipment by bolts. It is very troublesome to replace the pin, which is not conducive to the user's use. At present, there are two main technical solutions used in the market to fix the wooden shaft with a pin: one is to use a conical pin designed by Benninger of Germany with square steel and a ferrule. In actual operation, this method requires frequent replacement of square steels of different sizes to adapt to different wooden shaft apertures. The other is to use a square four-sided pin from Litzler of the United States. Although the configuration of square steel plus ferrules is removed, there is still a matching problem, that is, the pin and the wooden shaft aperture are often not correctly aligned at one time, and workers need to manually adjust the direction of the wooden shaft to align the edge of the pin with the shaft hole, which has low work efficiency. For the problems in the relevant technology, no effective solution has been proposed so far. Utility Model Content
