Perforating machine applied to preparation of medical dressings

Abstract

The invention relates to a perforating machine applied to preparation of medical dressings. The perforating machine applied to preparation of the medical dressings comprises a station switching mechanism, a dressing loading mechanism, a dressing positioning mechanism and a dressing perforating mechanism, wherein the station switching mechanism comprises a driving assembly and a rotating disk; multiple groups of positioning grooves matched with the dressings are formed on the rotating disk equidistantly along a circumferential direction of the rotating disk; the dressing loading mechanism comprises a lifting assembly, a guide assembly, a feeding assembly and a discharging assembly; the dressing positioning mechanism comprises a pressing assembly, a limiting plate and an inflating assembly for driving the pressing assembly to limit the dressings; the pressing assembly is elastically connected with the lifting assembly; the dressing perforating mechanism comprises a perforating assembly and an action limiting assembly; the perforating assembly is arranged corresponding to and matched with the pressing assembly and is arranged on the rotating disk in a sliding way; the action limitingassembly drives the perforating assembly to perform perforation work on the dressings; and the technical problems that continuous input and output of the dressing cannot be realized through mechanicalaction during manual dressing loading and discharging work, the working efficiency is low and the yield is low are solved.

Description

technical field [0001] The invention relates to the technical field of medical dressings, in particular to a punching machine used in the preparation of medical dressings. Background technique [0002] In the manufacture of the medical negative pressure drainage device, it is necessary to process the through hole on the medical dressing to accommodate the drainage tube. Because the medical dressing itself is relatively soft, it is very difficult to directly punch holes in the medical dressing, and it is difficult to control the perforation. At present, the commonly used method is to add water to the medical dressing and refrigerate until the medical dressing hardens, then insert the punching knife from one end of the hardened medical dressing, and extend the other end to complete the punching operation. However, using this method to punch holes in medical dressings is cumbersome and time-consuming, and punching holes in hard medical dressings is easy to produce debris, there...

Problems solved by technology

[0005] The purpose of the present invention is to address the deficiencies of the prior art, by setting the lifting assembly of the dressing upper loading mechanism to cooperate with the guide assembly, and then realize the automatic rise and fall of the lifting assembly, and automatically transmit the dressing to the pressing assembly when it is rising. It is conducive to the perforation of the dressing, and it is convenient for the dressing to be fed in and out during the lowering operation; and then the feeding component is used to realize the automatic loading of the dressing onto the lifting component, thus solving the problem of manual loading and discharging of the dressing, and at the same time, the continuous dressing cannot be achieved through mechanical actions Input and output, its work efficiency is low, and the technical problem of low output
