Manufacturing process of cutter for punching adhesive tape

Abstract

The invention relates to a manufacturing process of a cutter for punching an adhesive tape, comprising the following steps of: 1, respectively machining a hollow roller and a punching part; arranging a plurality of uniformly-distributed through holes on the outer periphery of the hollow roller; machining the punching part, wherein the punching part comprises a tapered head and column body parts, which are connected with each other; 2, inserting all the column body parts of the punching part into hollow roller through holes, and fixing by using a metal fixing agent; 3, polishing the top of the tapered head to enable the distance from each blade to a rotary axis of the hollow roller to be the same; and 4, polishing the top of the tapered head to enable the blades meet the sharpness for punching. According to the manufacturing process of the cutter for punching the adhesive tape, the manufactured cutter has good punching uniformity, does not generate noises, has fast production speed and can realize continuous production; the drilling part can be polished for a plurality of times and the service life is long; and the punching part is embedded into the hollow roller through holes so that only the punching part needs to be replaced if the blade is abraded and discarded, and the maintenance cost is low.

Description

technical field [0001] The invention relates to the field of adhesive tape manufacturing, in particular to a manufacturing process of a cutter for punching adhesive tape. Background technique [0002] Adhesive plaster is a widely used medical product, which has multiple functions such as fixing, cleaning and keeping warm. But common adhesive plaster is to coat one deck with strong viscous medical glue on cotton cloth, there is the shortcoming of airtightness, because the airtightness of adhesive plaster seriously affects its use effect, sometimes can make the wound not heal for a long time. Therefore, the surface of the current medical adhesive plaster generally has small round holes evenly arranged to facilitate wound ventilation and skin perspiration. [0003] The diameter of the evenly distributed small circular holes is usually 2mm-5mm, and the distance between the centers of two adjacent holes is 8mm-15mm. In the prior art, punching is often used to punch holes, and s...
