Description

Supporting roller for slicing of mask machine and mask machine

Technical Field

The utility model relates to a gauze mask machine is bearing roller and gauze mask machine for section.

Background

When the mask is processed, the non-woven fabrics placed in a coiled mode need to be folded together in a layered mode, shaping and edge sealing processing are conducted, then cutting processing is conducted, and a strip of non-woven fabrics is cut into a flaky mask sheet body. Such as the mask slicing device disclosed in patent document CN1101420980A, published as 2019.08.20, the device comprises four parts of welding, feeding, cutting and discharging, each part is provided with a roller, and the rollers are provided with different structures to realize different functions. For example, an ultrasonic welding machine is provided in the counter roll of the welding part, and the edges of the nonwoven fabric layers can be welded when the multilayer nonwoven fabric passes through the counter roll; the roller of the cutting part is provided with a cutter, and when the non-woven fabric layer passes through the roller of the cutting part, the cutter on the roller can cut the non-woven fabric into a flaky mask body.

At present, the device for cutting the non-woven fabric in the mask machine mostly adopts a pair-roller structure, which is the same as the cutting pair-roller group disclosed in the patent document with the publication number of CN206927332U and publication number of 2018.01.26, that is, a cutter is arranged on a first roller of a pair of rollers, the cutter extends along the axis of the first roller, and a second roller provides a bearing surface for the non-woven fabric layer to apply force by the cutter.

When the non-woven fabric layer passes through the position between the cutting roller pair groups, the cutter of the first roller and the outer peripheral surface of the second roller jointly extrude the non-woven fabric layer, so that the non-woven fabric layer is cut under the action of the cutter. During the cutting process, the cutter of the first roller is used as a force application part to provide shearing force for the non-woven fabric layer, and the outer peripheral surface of the second roller is used as a bearing part for supporting the non-woven fabric layer, so that the hardness of the non-woven fabric layer has certain requirements. At present, there are two main methods for ensuring the hardness of the second roller, one is to use a material with high hardness to manufacture the outer peripheral surface of the second roller, and the other is to heat-treat the second roller to improve the surface hardness thereof. Both methods have the problem of high production, operation and maintenance cost in practical application.
