Improved patch hobbing cutter

Abstract

The invention discloses an improved patch hobbing cutter. The improved patch hobbing cutter comprises a hollow cylinder, end covers connected to the two ends of the cylinder correspondingly and shaftheads installed on the end covers at the two ends. The end covers at the two ends are oppositely provided with a plurality of strip-shaped holes, and a connection shaft penetrating the cylinder is arranged between every two adjacent strip-shaped holes. The cylinder is provided with blades, and the two ends of each blade extend downwards to be movably connected with the part, extending out of the end cover, of the corresponding connection shaft. The two ends of each connection shaft are provided with fastening nuts to fix the parts, extending to the positions between the fastening nuts and theend covers, of the blades. According to the improved patch hobbing cutter, the relative distance between the adjacent blades is changed in a manner of adjusting the distance between the connection shafts or a manner of increasing or reducing the connection shafts, and therefore the function that the hobbing cutter in one specification can produce multiple specifications of absorbent cotton or adhesive tape is achieved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of patch production, in particular to an improved patch rolling cutter. Background technique [0002] The patch generally consists of medicinal cotton with medicinal effect, an adhesive plaster formed of woven or non-woven fabric covered on the medicinal cotton, and a release paper sandwiched between the two. In the process of patch production, both the cotton wool and the adhesive tape need to be cut into a fixed shape by a rolling cutter. Since the size and length of the patch are different, the specifications of the rolling cutter are also different. In the prior art, a hob cutter of one specification can only produce cotton wool or adhesive tape of a fixed specification, and when it is necessary to produce cotton wool or adhesive plaster of various specifications, the corresponding hob cutter needs to be replaced, but the disassembly of the hob cutter and It is more troublesome to replace, and there is ...

AI Technical Summary

Problems solved by technology

In the prior art, a hob cutter of one specification can only produce cotton wool or adhesive tape of a fixed specification, and when it is necessary to produce cotton wool or adhesive plaster of various specifications, the corresponding hob cutter needs to be replaced, but the disassembly of the hob cutter and It is more troublesome to replace, and there is no cutter of one specification on the market to produce roller cutters of cotton wool or adhesive tape of various specifications.
