Ear loop grabbing and welding device for mask machine

Abstract

The invention relates to the technical field of mask preparation devices, in particular to an ear loop grabbing and welding device for a mask machine. The ear loop grabbing and welding device for themask machine is characterized by comprising a bearing plate, a routing mechanism, a cam lifting mechanism, an ear loop grabbing and transferring mechanism, an ear loop welding mechanism and a mask tablet pressing mechanism. According to the ear loop grabbing and welding device for the mask machine provided by the invention, the lifting and lowering distances of the cam lifting mechanism are controlled easily, the lifting and lowering efficiency is high, and the stability is good; the ear loop grabbing and transferring mechanism is simple in structure arrangement and high in operation accuracy;and the ear loop welding mechanism and the mask tablet pressing mechanism are matched, so that mask tablets keep flat before ear loops are welded, the position accuracy and the welding success rate of ear loop welding are greatly improved, the running speed is greatly improved, the yield is increased, and the noise is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of mask preparation devices, in particular to a tape-taking and welding device for a mask machine. Background technique [0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, to block harmful gases, odors, droplets, viruses and other substances from entering and exiting the wearer's mouth and nose, with gauze or paper, etc. Made of material. [0003] During the production process of masks, ear straps need to be installed on both sides. The lifting mechanism on the mask machine drives the tape-taking jaws to move down as a whole. The two tape-taking jaws on the same side of the mask machine are initially on the same straight line. The two ends of the earband are clamped horizontally by the two claws, and then the two ends of the earband are rotated at a certain angle to expose the two ends of the earband under the earband ...

AI Technical Summary

Problems solved by technology

[0004] There are still many deficiencies in the existing tape-taking and welding devices for mask machines, for example: (1) The structure of the rotary assembly of the tape-taking air claws is complicated to set, and the rotation angle is prone to deviation, which not only has low work efficiency, but also fails to install the ear straps (2) The welding head directly welds the end of the ear straps to the main body of the mask. Due to the poor flatness on both sides of the main body of the mask, deviations are prone to occur during the welding process; (3) The structure of the pressing mechanism is fixed and cannot Fine-tuning according to the actual production situation, it is inconvenient to disassemble, it is not conducive to repair and replacement of parts, some uneven mask pieces are easy to be stuck at the feeding end of the tablet pressing mechanism, affecting the normal transportation of subsequent masks, and the masks cannot be monitored in real time Whether the tablet passes through the tablet pressing mechanism smoothly; (4) The lifting and lowering distance of the lifting mechanism is not easy to control, the efficiency is slow, and the stability needs to be improved; (5) The noise is loud during operation, which affects the physical and mental health of the operator
