Problems solved by technology

However, this earband forming method requires cutting the mask first, and then welding the four connection points. The joint position is not uniform during manual welding, the product quality is poor in uniformity, and it takes a long time. The automatic welding equipment is complicated. The investment cost of equipment is high and it is not easy to maintain. At the same time, the contact area of ​​the ear loops of the mask formed in this way is small, and the problem of separation between the ear loops and the mask is prone to occur.

Abstract

The invention discloses a molding device and a molding method for ear straps of a mask, belonging to the technical field of masks. The molding device includes a frame, an ear strap forming mechanism arranged on the frame, an outer layer conveying mechanism, a middle layer conveying mechanism, Inner layer conveying mechanism, composite roller, pressing machine and side sealing machine. In this forming method, the ear strap material for preparing ear straps is divided by a dividing machine and then connected to both sides of the outer layer material of the mask part. At the same time, the pressing machine is used to The lug material, outer layer material, middle layer material and inner layer material are pressed together at the same time. The molding device and molding method greatly reduce the time required for separately preparing the mask part and the earband part, and then welding the earbands, and improve production efficiency. At the same time, the divided ear hanging material is completely in contact with the side part of the outer layer material The connection greatly improves the stability of the connection after the ear strap is made, which not only improves the production efficiency but also improves the quality of the resulting product.

Description

technical field [0001] The invention belongs to the technical field of masks, and in particular relates to a molding device and a molding method for ear straps of a mask. Background technique [0002] As a wearable device, the mask is worn on the face through the ear straps to cover the mouth and nose. It can effectively filter pollen, PM2.5 particles, and pathogenic microorganisms in the air from invading the human respiratory tract. Diseases, respiratory diseases, effective means to protect the health of personnel. As a means of non-pharmaceutical intervention, masks play an irreplaceable role in preventing foreign matter from entering the respiratory tract, reducing disease transmission, and responding to sudden biological contamination incidents. Present mouth mask mainly is made up of two ear bands of mask part and both sides, and ear band is the elastic rope that section is circular or oblate usually. In the process of processing, in order to firmly combine the ear s...
