A polymer medical bandage base cloth rolling machine

Abstract

The invention discloses a high polymer medical bandage base cloth rolling-up machine. The high polymer medical bandage base cloth rolling-up machine comprises a receiving hopper, a base cloth shaping mechanism and a rolling-up mechanism, wherein the receiving hopper comprises a plurality of base cloth chambers formed by dividing the receiving hopper through partitions; the receiving hopper receives base cloth of a weaving loom; the base cloth shaping mechanism comprises a shaping rod I, a pressing rod and a shaping rod II; the shaping rod I and the pressing rod are mounted on a lower rack body of a shaping rack; the shaping rod II is mounted on an upper rack body of the shaping rack; the rolling-up mechanism comprises a rolling-up rack, a rolling-up device and a rolling-up motor; the rolling-up device is mounted on the rolling-up rack; the rolling-up motor is connected with the rolling-up device; and an output shaft of the rolling-up motor is further connected with the shaping rod II. According to the receiving hopper, the base cloth is buffered before the base cloth is rolled up, time is also gained for change of a rolling-up roller, and the circumstance that the weaving loom stops to wait for changing of the rolling-up roller is avoided; the base cloth shaping mechanism automatically shapes the base cloth, deviation is prevented, meanwhile, linear velocity change of the rolling-up roller due to increasing of a roll is adjusted, and therefore, rolling-up elasticity meets requirements of the following process; and by quick joints, cleaning for changing of the roller is facilitated, and the time is saved.

Description

technical field [0001] The invention relates to a polymer medical bandage base cloth rolling machine, which belongs to special polymer medical bandage production equipment. Background technique [0002] The orthopedic external fixation material routinely used in the medical departments of most developing countries in the world is still the traditional plaster bandage. The plaster bandage has been used in clinical practice for more than a hundred years, but its defects such as bulkiness, fragility, deliquescence, and heavy dust pollution are also prominent. As a cost-effective new fixation material, polymer bandages have begun to replace plaster in the production of bandage products. The polymer fixed bandage uses glass fiber base cloth and polyester fiber base cloth as the base layer, and uses high-activity polyurethane as the coating, which not only overcomes the shortcomings of plaster bandages, but also has better performance, and the market prospect is quite broad. The ...

AI Technical Summary

Problems solved by technology

[0003] Since the polymer fixed bandage uses glass fiber base cloth and polyester fiber base cloth as the base layer, the production of these base cloths adopts traditional textile machines, and a pair of rollers are used at the receiving end. The winding mechanism composed of the winding roller and the friction wheel winds up. The friction wheel sticks the base fabric tightly to the winding roller for winding, which causes the base fabric to be stretched and deformed, and the winding is too tight. In the subsequent process The production quality is affected when releasing; and the existing winding equipment cannot achieve moderate elasticity, the reason is that the speed of the loom is a fixed value at a constant speed, and during the rolling process, as the volume increases, the line speed follows Changes, resulting in the existing equipment can not be solved; and the use of manual rolling is time-consuming, laborious, inefficient, and simply not feasible

[0004] Since this technology is still in the initial stage of R&D and production, there is no dedicated production equipment, and general-purpose equipment cannot adapt to the production process of this product, so special research and development is required.
