A welding machine for mask ear loops

Abstract

The invention relates to mask production equipment. A mask earband welding machine, including a moving frame, a lead screw assembly, a thread trimming mechanism, an earband feeding assembly, a first cylinder, a lifting frame, a rotating assembly, an earband transfer assembly, a welding column, a push belt assembly, and an entrainment assembly The moving frame is connected to the frame through slide rails, the screw assembly is arranged on the frame, and the moving part of the screw assembly is connected with the moving frame; the moving frame includes an upper platform and a lower platform. Platform, the thread trimming mechanism is installed on the lower platform, and the ear belt feeding assembly is arranged on the upper platform; the lifting frame is connected to the mobile frame; the ear belt transfer assembly is installed on the side of the lifting frame, The push belt assembly and the entrainment assembly are respectively installed on both sides of the lower end of the lifting frame. The invention has the advantages of reliable and efficient ear band welding and compact structure.

Description

technical field [0001] The invention relates to mask production equipment, in particular to a mask earband welding machine. Background technique [0002] There are many types of masks on the market, including flat masks, vertical masks, cup-shaped masks, folding masks, etc. There are also many types of equipment for producing masks. At present, most of the masks produced by the mask manufacturing industry are made by hand or semi-automatically. In the production of equipment, a mask needs three to four processes before it can be made into a finished product, and the process is quite complicated and cumbersome. Moreover, masks are produced using simple equipment combinations, with high labor costs and low production efficiency. Especially, the upper bands are generally welded by the staff manually, and the work intensity is high. [0003] The State Intellectual Property Office has published the publication number CN204146395U, and the patent name is a patent for a fully auto...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the welding of the earbands in the existing mask production technology requires the swing action of the lead wire and the wire, which leads to low efficiency of earband welding. The earbands are directly clamped by the finger cylinder, and the direct movement of the earbands causes the entire mechanism to be oversized. To solve the problem of complex earband cutting mechanism, provide a reliable, efficient and compact mask earband welding machine
