Before the mechanism starts, a long head band is led into the head band feeding and clamping mechanism 4 through the head band discharging mechanism 28, then the head of the head band sequentially passes through the head band guide wheel 43, the head band inductor 48 and the head band pressing block clamping groove 44 through manual operation, and the head of the head band finally extends out of the inner side face of the head band pressing block clamping groove 44 for a distance, so that the head band is conveniently clamped by the subsequent horizontal head band clamping mechanism 5, the head band inductor 48 can sense whether the head band supplies materials in real time during working, and if the head band is sensed to be short of materials, the mechanism can immediately stop working and give a corresponding alarm.

After the headband is threaded in place, the mechanism is started, firstly, the headband lower pressing block lifting air cylinder 46 drives the headband lower pressing block 47 to move downwards to be clamped with the headband lower pressing block clamping groove 44 and press the headband, meanwhile, the headband cutting mechanism 6 opens the knife edge, then the horizontal headband clamping mechanism 5 works, the horizontal transmission belt servo motor 55 drives the horizontal transmission belt 53 to rotate forwards through the transmission belt transmission block 52, so as to drive the headband horizontal clamping jaw driving air cylinder 58 and the headband horizontal clamping jaw 59 on the headband horizontal clamping jaw sliding block 56 to move leftwards along the horizontal auxiliary guide rod 54 to the inner side surface of the headband lower pressing block clamping groove 44, the headband horizontal clamping jaw driving air cylinder 58 drives the headband horizontal clamping jaw 59 to clamp the pressed headband head, then the horizontal transmission belt servo motor 55 drives the horizontal transmission rod 53 to rotate backwards through the transmission belt transmission block 52, so as to drive the headband horizontal clamping jaw driving air cylinder 58 and the headband horizontal clamping jaw 59 on the headband horizontal clamping jaw sliding block 56 to rotate rightwards along the horizontal auxiliary guide rod 54 The headband moves and resets, at the moment, the headband is pulled out by a length under the horizontal pulling of the horizontal clamping jaw 59 of the headband, and meanwhile, the length of a piece of mask cloth 3 is fed into the mask cloth supporting frame 2 of the bottom plate 1 and reaches a headband welding station.

The rotation time of the horizontal belt servo motor 55 is controlled by the two headband horizontal jaw slide in-place sensors 21 located at the left and right extreme positions of the headband horizontal jaw slide 56, when the headband horizontal jaw slide in-place sensor 21 located at the left side senses, the headband horizontal jaw slide 56 reaches the headband horizontal clamping end, and when the headband horizontal jaw slide in-place sensor 21 located at the right side senses, the headband horizontal jaw slide 56 reaches the reset end.

After the headband is pulled out by a certain length, the headband lower pressing block lifting cylinder 46 drives the headband lower pressing block 47 to move downwards again to be clamped with the headband lower pressing block clamping groove 44, and the remaining headband behind is pressed; then the two headband rotating clamping jaws 203 are driven by the corresponding headband rotating clamping jaw rotating servo motor 201 to rotate to the positions right above the left end and the right end of the pulled headband, then the rotating headband clamping mechanism upper and lower servo motor 12 drives the rotating headband clamping mechanism 20 to integrally move downwards, so that the left headband rotating clamping jaw 203 and the right headband rotating clamping jaw 203 are lowered to the same position height as the headband, then the two headband rotating clamping jaws 203 clamp the left end and the right end of the pulled headband under the driving of the corresponding headband rotating clamping jaw driving cylinders 202 respectively, and finally the headband cutting mechanism 6 works to cut the pulled headband.

After the headband is cut off, the two headband rotating clamping jaws 203 are driven by the corresponding headband rotating clamping jaw rotating servo motor 201 to rotate to the positions right above the welding points of the left and right headband, and the left and right ends of the headband are ensured to be smoothly rotated to the welding points of the left and right headband due to the limitation of the headband middle point limiting steel wire 27, and meanwhile, the middle part of the headband is prevented from being mistakenly twisted into the welding points of the headband; then the upper and lower servo motors 12 of the rotating head band clamping mechanism drive the rotating head band clamping mechanism 20 to continuously move downwards integrally, so that the left and right head band rotating clamping jaws 203 and the left and right ends of the head band are descended to the head band welding points of the section of the mask cloth 2 to be welded.

After the two ends of the head band are in place, the welding lifting cylinder 9 works to drive the welding head mounting plate 10 to move downwards until the two welding heads 11 respectively press the left end and the right end of the head band, and then the two welding heads 11 simultaneously weld the head band on the head-mounted mask green body. After the two ends of the head band are firmly welded, the welding lifting cylinder 9 drives the welding head mounting plate 10 to move upwards, so that the two welding heads 11 are separated from the mask finished product respectively, then the head band rotating clamping jaw 203 releases the welded head band under the driving of the head band rotating clamping jaw driving cylinder 202, and the initial position height is reset under the driving of the upper servo motor 12 and the lower servo motor 12 of the rotating head band clamping mechanism, then the head band rotating clamping jaw 203 returns to the initial position of clamping the head band respectively under the driving of the head band rotating clamping jaw rotating servo motor 201, the next clamping is waited, finally, the head-worn mask finished product of the section of mask cloth 2 which completes the welding of the head band is sent out of a head band welding station, and the next section of mask cloth 2 enters the ear band welding station. The process is repeated, and the high-speed cutting and welding work of the mask head band can be realized.

In the actual production process, the two mechanisms can be used in parallel front and back, the former mechanism is responsible for cutting and welding one head band in the head-wearing mask, and the latter mechanism is responsible for cutting and welding the other head band in the head-wearing mask, so that the front head band and the rear head band of the head-wearing mask are simultaneously cut and welded.

If the two head bands of different lengths of the head-wearing mask are met, the size of one mechanism of the two mechanisms can be reduced to form a short head band cutting and welding mechanism, and the other mechanism is oppositely formed into a long head band cutting and welding mechanism, so that the cutting and welding of the front head band and the rear head band of different lengths are met.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
