Automatic welding machine for ear straps of face mask

Abstract

The invention discloses an automatic welding machine for ear straps of a face mask. The automatic welding machine for the ear straps of the face mask comprises a rack. An equipment platform is arranged on the rack, a mask conveying mechanism, a thread feeding mechanism, a thread winding mechanism, a thread shearing mechanism, a welding mechanism, a stacking mechanism and a controller are arrangedon the equipment platform, and the thread feeding mechanism, the thread winding mechanism, the thread shearing mechanism and the welding mechanism are arranged above the mask conveying mechanism. Thestacking mechanism is arranged at the output end of the mask conveying mechanism, the mask conveying mechanism comprises two chain wheel supports, a driving double-chain wheel and a driven double-chain wheel, two parallel and tensioned chains are arranged between the driving double-chain wheel and the driven double-chain wheel, and the two chains are both located on the surface of the equipment platform. A plurality of flat plate type mask carriers are transversely and evenly laid on the two chains. The automatic welding machine for the ear straps of the face mask has the beneficial effects that the conveying positioning precision is high, the average transmission ratio is accurate, the transmission is stable, the efficiency is high, the transmission power is high, the overload capacity ishigh, the high-speed performance is excellent, and maintenance and debugging are convenient.

Description

technical field [0001] The invention relates to the technical field of mask ear strap machines, in particular to an automatic welding machine for mask ear straps. Background technique [0002] Mask is a kind of personal hygiene protective equipment, which is used to filter the air in the mouth and nose, so as to prevent harmful gases, droplets, dust, viruses, etc. from entering and exiting the wearer's mouth and nose. Air has a certain filtering effect, usually made of gauze or melt-blown cloth, non-woven fabric, etc. When respiratory infectious diseases are prevalent or when working in dusty and other polluted environments, germs and dust in the air can enter the human lungs through breathing and cause serious damage to the body. Wearing a mask can play a certain role in filtering. The mask generally includes a mask body and ear straps. The ear straps are fixed on the left and right sides of the mask body and there are four fixed points. [0003] In the production of exis...

Problems solved by technology

[0005] Although the above-mentioned ear belt machine has improved the production efficiency to a certain extent, because the conveying device of the mask body adopts a general belt conveyor belt, the lower part of the conveyor belt needs to be wound under the frame, and the motor adopts an ordinary motor, so the transmission stroke Long, low production efficiency during processing, the conveyor belt is not rigidly connected, has low tension, and is prone to deformation, resulting in the inability to achieve accurate positioning of the mask body conveying, and it is very easy to cause deviations in the position of the mask body and ear straps during welding, resulting in The unqualified rate is very high; in addition, the existing welding mechanism on the market is not compact enough in structure, and the coordination rhythm of each action is slow, resulting in low production efficiency
