Problems solved by technology
[0004] That is, after a mask is conveyed in place, the connection of the ear straps on one side needs at least four actions: clamping, cutting, bending, and pressure welding. °Carry out pressure welding on both sides, and if a fully automatic pressure welding device is used, the production efficiency is improved compared to semi-automatic, but the pressure welding devices on both sides need a higher synchronization rate, so it will produce a higher failure rate. After A period of production time requires professionals to debug the system, and even if fully automatic production is adopted, when the air grippers under the control of the controller are in motion, the response time required for each step will still not change, and the production of masks is still subject to ear straps welding efficiency

Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0038] As shown in the figure, a high-speed pressure welding method for ear straps of a mask, by setting 8 cyclically moving wire-drawing units on the base 3, these wire-drawing units pass through the winding station, clamping station, and cutting station when rotating , pressure welding station, respectively complete the steps of winding, clamping, cutting, pressure welding and so on. Between the above stations, no additional actions can be called transition stations. When manufacturing mechanical parts, the transition station The position will leave a more generous design space for the process, and the transmission parts will not affect each other, and setting a larger number of wire-drawing units will not increase the pressure-welding speed of the ear straps.
[0039] The pulling unit includes a fixed base 11 and a lifting base 12. The lifti...

The invention relates to the field of mask production, in particular to a high-speed pressure-welding method for ear loops of a mask. By cyclically moving several wire-drawing units so that the wire-drawing units are located at different stations, winding, clamping, cutting, and pressure welding are respectively completed. The wire is to wind the ear rope on the pulling unit and bend it to conform to the shape of the standard mask ear strap. The clamping is to fix the bent ear strap, the cutting is to cut the continuous ear strap into an ear strap, and the pressure welding is to connect the ear strap. onto the mask. After adopting the above scheme, the pressure welding efficiency of the ear straps of the mask is greatly improved through creative design.
Description
technical field [0001] The invention relates to the field of mask production, in particular to a high-speed pressure welding method for ear loops of a mask. Background technique [0002] When a large-scale epidemic breaks out, in order to prevent cross-infection, both healthy and infected people should wear masks. However, due to the large population in China, the daily consumption of masks is huge, so the production efficiency of masks is very important. [0003] In the production of masks, two ear straps need to be pressure-welded on both sides of the mask. In the production of existing masks, the ear strap welding device is installed on the side of the mask conveyor belt. The pressure welding of the ear straps generally includes the following steps: The ear rope of the earband is pulled to the side of the conveyor belt, and is clamped left and right by two air claws, and then the ear rope is cut off by the cutter mechanism to form an earband that meets the standard size, ...
