Non-woven fabric winding barrel for mask production

Abstract

The invention discloses a non-woven fabric winding barrel for mask production. The non-woven fabric winding barrel comprises two half barrels, a plurality of extension plates are fixedly connected to the ends, close to each other, of the two half barrels, strip-shaped grooves are formed in the outer surfaces of the opening ends of the half barrels, and the extension plates are located in the strip-shaped grooves in the surfaces, not fixedly connected with the extension plates, of the half barrels. Two half barrels are pulled or pushed to move, inserting rods are inserted into corresponding inserting holes, then the two half barrels rotate, when the half barrels rotate, guide rods on the surfaces of cross rods rotate to the bottoms, inclined rods inserted into the surfaces can be inserted into inclined holes, then air in the inclined holes is pressed out, the air pressed out can enable the edge of the non-woven fabric to get close to an adjacent blocking ring, then the non-woven fabric can be prevented from wrinkling in the winding process, the air pressed out can blow off scraps in the cutting position of the edge of the non-woven fabric from the surface of the non-woven fabric, and the residual probability of the scraps is reduced.

Description

technical field [0001] The invention belongs to the technical field of mask production, and in particular relates to a non-woven cloth wrapping cylinder for mask production. Background technique [0002] During the use of the existing cloth winding drum, in order to prevent the narrow cloth from being wound on its surface, a wide range of winding occurs, resulting in uneven thickness and deformation of the non-woven fabric. The width of the cylinder is small, but because of its specific width, for wider non-woven fabrics, it is necessary to replace a wider winding cylinder for use, which is cumbersome to replace, and because the wider non-woven fabric is When winding, in the process of pulling, affected by the tension, it is easy to cause the non-woven fabric to wrinkle to the middle, which will affect the subsequent mask production. [0003] Therefore, it is necessary to invent a non-woven fabric winding drum for mask production to solve the above problems. The probabilit...
