Background
When the large-scale epidemic situation outbreak occurs, no matter healthy people or infected people wear the mask in order to prevent cross infection, and the daily consumption of the mask is huge due to the large number of people in China, so the production efficiency of the mask is very important.
During the gauze mask is in production, need two ear areas of pressure welding in face guard both sides, in current gauze mask production, ear area pressure welding device sets up at face guard conveyer belt side, and the pressure welding of ear area generally includes following step: the ear rope as the ear belt is pulled beside the conveying belt, is clamped left and right through the two gas claws, is cut off by the cutter mechanism to form the ear belt which accords with the standard size, and then the two gas claws are controlled to rotate towards the conveying belt to enable the ear belt to be in a U-shaped structure, and then the ear belt is pressure-welded on the side edge of the face mask through the two pressure-welding devices.
Namely, after a face mask conveying in place, the connection of one side ear area needs four actions such as centre gripping at least, cut off, the bending, pressure welding, on the semi-automatic production line, the pressure welding device only sets up in conveyer belt one side, need artifical manual pressure welding that rotates 180 to carry out both sides to the gauze mask, and if adopt full-automatic pressure welding device, compared in semi-automatic production efficiency that has improved, but the pressure welding device of both sides needs higher synchronous rate, consequently can produce higher fault rate, need professional to debug the system promptly through a period of production time, and even adopt full-automatic production, the gas claw under controller control is when the action, the response time that each step needs still can not change, the production of gauze mask still receives the pressure welding efficiency of ear area.
Therefore, the present inventors have further studied this and developed a high-speed ear belt machine, which is produced by this invention.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a high-speed ear belt machine, through creative design, very big improvement the pressure welding efficiency of gauze mask ear belt.

the ear straps are pressure welded to the mask by a pressure welding mechanism.
After the scheme is adopted, through the action of the most basic wire drawing unit at different positions, namely when the ear belt is subjected to pressure welding, the pressure welding point is only required to be subjected to pressure welding all the time, the rest bending, fixing and cutting steps are completed at the previous station, and the response of other steps is not required to be waited at the same station; the cutting mechanism can adopt the prior art means, only needs to be matched with the rotation of the wire pulling unit, and can cut the lug rope after the lug rope is clamped and fixed, and the pressure welding mechanism also adopts the prior art, and adopts a welding gun to apply pressure on the lower part and the upper part, or adopts the welding gun to apply pressure on the upper part and the lower part.
Furthermore, the wire supply unit pulls the ear rope to do reciprocating linear motion, so that the ear rope is limited by the winding piece of the wire pulling unit to form a curve state in a manner of matching with the movement of the wire pulling unit in the process of swinging back and forth.
The ear ropes pulled by the wire pulling unit sequentially pass through the winding pieces of the wire pulling unit in the linear reciprocating motion process by matching with the circulating rotation of the wire pulling unit to form wave-shaped distribution, so that the ear ropes are conveniently cut in subsequent stations to form bent ear belts; in the prior art, after the ear rope is cut off, the air claws at two sides are controlled to be bent and formed towards the same side; in the scheme, the wire supply unit takes the linear lifting guide rail as a main traction path, the lead wire of the traction lug rope is linked with the main driving mechanism through the connecting rod, the distribution of the lug rope on the winding piece is realized only through purely mechanical linkage, but the wire supply unit in the prior art can also be adopted, the wire supply is realized through electric control, and the synchronism is slightly different from the scheme.
