Plane mask ear band welding machine

Abstract

The invention provides a plane mask ear band welding machine. The machine comprises an assembly plate, a conveying device, two ear band welding devices and two ultrasonic transducers; the conveying device comprises a driving mechanism, two conveying chains and jigs, wherein the two conveying chains are arranged in parallel with each other and side by side, the driving mechanism controls the two conveying chains to move, the jigs are separately positioned on the two conveying chains, and a plane mask is placed on the jigs; the assembly plate is positioned above the conveying chains in the vertical direction, the two ear band welding devices are arranged in a mirror image with respect to the jigs; the two ear band welding devices are arranged staggered in the moving direction of the conveying chains; and each ear band welding device comprises a fixing plate, a moving plate, a first cylinder, a linkage plate, two linkage rods, two pressure springs, two welding heads, a rotating disc, a driving motor, a second cylinder, a third cylinder, two abutting heads, two abutting plates and a yarn pressing plate. The plane mask ear band welding machine can produce inner ear masks and outer ear masks, and is convenient in operation, high in production efficiency and low in production cost.

Description

technical field [0001] The invention relates to the technical field of automatic production equipment for flat masks, in particular to a welding machine for ear straps of flat masks. Background technique [0002] The flat mask includes a cover body, which is formed by laminating multiple layers of fabrics, such as non-woven fabrics. Both sides of the cover body are provided with ear straps for wearing the mask on the user's ears. The ear bands 12 of the general plane mask are arranged on the outer sides of the two ends of the cover body 11, commonly known as the outer ear mask 1, see figure 1 shown. In order to facilitate the packaging of flat masks and reduce the size of the mask packaging bag or box, the ear straps 22 of the flat masks are arranged inside the two ends of the cover body 21, commonly known as inner ear masks 2, see figure 2 shown. [0003] At present, when welding the earbands of the flat mask, the outer ear mask 1 and the inner ear mask 2 cannot share ...

AI Technical Summary

Problems solved by technology

[0003] At present, when welding the earbands of the flat mask, the outer ear mask 1 and the inner ear mask 2 cannot share a flat mask earband welding machine for production, so it is necessary to design different earband welding machines according to the outer ear mask 1 and the inner ear mask 2, Greatly increased the production cost of the enterprise

At the same time, the existing earband welding machine can only meet the production of flat masks of one length and size, so it is necessary to design multiple earband welding machines according to different lengths of flat masks, which greatly increases the production cost of the enterprise and improves the production efficiency. lower
