Problems solved by technology

[0002] Polyurethane foam wound dressings can promote wound healing, and have been favored by the market in recent years. However, the preparation methods of some polyurethane foam wound dressings on the market are too complicated. For example, the patent with publication number CN111748071A has cumbersome steps, complicated operations, and takes a long time. , and the aging step is difficult to prepare in large quantities at the same time, the preparation cost is high, the efficiency is also reduced, and the practicability is poor. As for the preparation device, most devices can only process a small amount of dressing at a time, and the production efficiency is low. Actual benefits, and poor flexibility, it is difficult to adjust the size, shape and other specifications of the dressing, which is not conducive to promotion and use

Abstract

The invention discloses a preparation method and a preparation device for preparing a polyurethane foam wound dressing, and relates to the technical field of polyurethane foam dressings. The preparation method for preparing the polyurethane foam wound dressing comprises three steps of mixing, cutting and pressing. The preparation device for preparing the polyurethane foam wound dressing comprises a base, and a sleeving coiling mechanism, a feeding mechanism, a material injection mechanism, a pressing mechanism, a feeding box and a material storage barrel are arranged on the base. According to the preparation method for the polyurethane foam wound dressing, the dressing is designed in a split type structure, the dressing is integrally formed in a pasting and pressing manner in the preparing process, the steps are simplified, operation is convenient, and the shape and specification of the dressing can be correspondingly adjusted according to production requirements. According to the preparation device for the polyurethane foam wound dressing, batch operation can be achieved, the processing time consumption is shortened, machine automatic operation is achieved, manpower input is reduced, and the labor burden of operators is relieved.

Description

technical field [0001] The invention relates to the field of polyurethane foam dressings, in particular to a preparation method for manufacturing polyurethane foam wound dressings and a preparation device thereof.
