Abstract

The invention provides a mask ear belt mounting mechanism. The mask ear belt mounting mechanism comprises a fixing frame, two identical ear belt mounting devices are arranged on the fixing frame, and each ear belt mounting device is composed of a pushing device, a rotary length control device and a wire passing device; each pushing device comprises a pushing air cylinder, a pushing seat is fixed to each air cylinder shaft, two opposite pushing shafts are fixed to each pushing seat, and ultrasonic welding heads are fixed to the bottoms of the pushing shafts; each rotary length control device comprises an air cylinder fixing seat, and the pushing shafts penetrate through the air cylinder fixing seats and are in clearance fit with the air cylinder fixing seats; meanwhile, the ultrasonic welding heads are located on the bottom faces of the air cylinder fixing seats, rotary air cylinders are fixed to the air cylinder fixing seats, and rotary shafts penetrate through the air cylinder fixing seats to be fixed to rotary seats; four clamps are correspondingly distributed on the rotary seats, two T-shaped length control seats are further fixed to the rotary seats, and clamp closing air cylinders and clamp opening air cylinders for controlling the clamps to be loosened or clamped are further arranged on the air cylinder fixing seats; and each wire passing device comprises a wire rod I and a wire rod II which are provided with wire holes, and the two wire rods are both fixed to the air cylinder fixing seats.

Description

technical field [0001] The invention relates to a component of a mask processing machine, in particular to a mask upper ear strap mechanism. Background technique [0002] In the manufacturing process of existing masks, the cords used for the ear loops need to be uniformly cut to length by a machine, and then the ear loops are rotated into a U shape by manual two hands, and then the two ends of the ear loops are placed on the two ends of one side of the mask. , and then step on the control switch of the mask processing machine with your feet, so that the ultrasonic welding head on the mask processing machine is pressed down on the ear strap and the mask for welding. After welding the ear strap on one side of the mask, turn the mask to perform the ear strap on the other side. Band welding, the existing method of uniformly cutting the length of the ear bands by a machine is too inefficient in the production of masks by manually rotating and bending the ear bands for welding. ...
