The welding head 5 can be a thermal welding head or an ultrasonic welding head, and when the welding head 5 is a thermal welding head, the welding head comprises an electric heating wire and a hot frit, and the welding head heats the ear belt and the mask body through heat generated by the electric heating wire so as to enable the ear belt and the mask body to be thermally fused into a whole; when the welding head is an ultrasonic welding head, the welding head comprises an ultrasonic oscillation circuit, a transducer, an amplitude transformer and a module, the welding head generates high-frequency oscillation through the ultrasonic oscillation circuit and the transducer, and further drives the module to vibrate at high frequency through the amplitude transformer, so that the ear belt and the mask body vibrate at high frequency, and under the condition of pressurization, the surfaces of the ear belt and the mask body are rubbed with each other to form fusion between molecular layers, and therefore welding is performed. The assembly plate 1 outside the welding head 5 is provided with pneumatic scissors through the mounting plate 6 so as to cut off the ear belt through the pneumatic scissors, thereby segmenting the ear belt. Because the feeding, sectioning and welding of the ear belt are all automatically carried out, the labor intensity can be effectively reduced and the production efficiency can be improved compared with the manual feeding of the ear belt.

The reset spring 9 drives the clamping plate 8 to rotate by taking the pin shaft as the axis through the elasticity of the reset spring 9, thereby driving the end of the bending clamping plate 8 to open with the rotating disk 4.
The pneumatic scissors comprise a scissors body 10 and driving air cylinders 11 which are respectively connected to the tail ends of handles of the scissors body 10, and the handles of the scissors body 10 are respectively driven to move by the driving air cylinders 11, so that the cutter head of the scissors body 10 is driven to move, the scissors body 10 is driven to open and close, the ear bands are sheared, and the ear bands are segmented.
The rotating disks 4 below the welding heads 5 are respectively provided with guide grooves 12, on one hand, the welding heads 5 are avoided through the guide grooves 12, and on the other hand, the welding heads 5 are guided through the guide grooves 12, so that the welding heads 5 are prevented from being deviated.
The assembly plate 1 on one side of the pneumatic scissors is provided with a fixed rod 13, the bottom end of the fixed rod 13 is fixedly provided with an upper push plate 14, the upper push plate 14 is arc-shaped, and the upper push plate 14 is in sliding connection with the end of the clamping plate 8 on the outer side of the reset spring 9. The upper push plate 14 is used for pushing the end of the clamping plate 8 on one side of the return spring 9 to lift up against the elastic force of the return spring 9, so that the bent end of the clamping plate 8 moves towards the rotating disc 4, and the ear belt clamp on the circumferential surface of the rotating disc 4 is fastened on the circumferential surface of the rotating disc 4, so that the rotating disc 4 can drive the ear belt to move in the rotating process. The end of the upper push plate 14 far away from one side of the pneumatic scissors is wedge-shaped, and the end of the upper push plate 14 is inserted below the clamping plate 8, so that the end of the clamping plate 8 is guided to move upwards to the push plate 14, and the upper push plate 14 can push up the end of the clamping plate 8. The assembly plate 1 at the other side of the pneumatic scissors is provided with a pressing cylinder 15, the end head of a piston rod of the pressing cylinder 15 penetrates through the assembly plate 1 to extend to the lower side of the assembly plate 1, the end head of the piston rod of the pressing cylinder 15 extending to the lower side of the assembly plate 1 is provided with a pressing plate 16, the pressing plate 16 is arc-shaped, and the pressing plate 16 is in abutting connection with the end head of the clamping plate 8 at the outer side of the rotating disc 4. The pressing cylinder 15 is used for driving the pressing plate 16 to lift through the pressing cylinder 15, and in the process that the pressing cylinder 15 drives the pressing plate 16 to move downwards, the pressing plate 16 extrudes the end of the bent clamping plate 8 to push the end of the clamping plate 8 to move towards the circumferential surface of the rotating disc 4, so that the clamping plate 8 overcomes the elasticity of the reset spring 9 to fasten the ear belt clip on the circumferential surface of the rotating disc 4; in the process that the pressing cylinder 15 drives the pressing plate 16 to move upwards, the pressing plate 16 does not press the clamping plate 8 any more, so that the clamping plate 8 can be opened under the elastic force of the reset spring 9. The end of the pressing plate 16 on one side of the pneumatic scissors is wedge-shaped, so that the clamping plate 8 is guided between the pressing plate 16 and the circumferential surface of the rotating disc 4 through the wedge-shaped end of the pressing plate 16.
Guide rods 17 are respectively arranged at the two end heads of the pressing plate 16, and the guide rods 17 are connected with the assembly plate 1 in an inserting way through guide cylinders 18.

After the pressing plate 16 descends to the right, the driving motor 2 is started, and the rotating disc 4 is driven to rotate 180 degrees through the driving motor 2. In the rotating process of the rotating disc 4, the end of the clamping plate 8 of the fixed clamping jaw sequentially moves to the upper pushing plate 14, after the clamping plate 8 moves to the upper pushing plate 14, the upper pushing plate 14 pushes the end of the clamping plate 8 on the outer side of the reset spring 9 to lift upwards to clamp and fix the ear belt on the rotating disc 4, and the rotating disc 4 drives the fixed ear belt to rotate. After the ear belt end rotates beyond the pneumatic scissors, the clamping plate 8 for fixing the clamping jaw enters between the pressing plate 16 and the rotating plate 4, the ear belt is kept clamped continuously under the action of the pressing plate 16, the rotating plate 4 is guaranteed to continuously drive the ear belt to move until the rotating plate 4 rotates 180 degrees, and in the process, the ear belt end rotates from one side of the pneumatic scissors to the lower side of the welding head 5 on the opposite side of the pneumatic scissors. After the rotary disk 4 rotates in place, a driving cylinder 11 of the pneumatic scissors is started to push a scissor body 10 to act, and ear belts are sheared by the middle parts of guide grooves 12. After the ear belt is cut off, the lifting cylinder 3 is started, the lifting cylinder 3 drives the welding head 5 to move downwards, and the welding head 5 pushes the ear belt to be pressed downwards to the mask body 1 to weld the ear belt and the mask body 1. After welding is completed, the lifting cylinder 3 drives the welding head 5 to reset upwards. After the welding head 5 is reset, the pressing cylinder 15 drives the pressing plate 16 to reset, so that the pressing plate 16 does not squeeze the clamping plate 8 any more, and the ear belt can be separated from the rotating disc 4. The ear belt is separated from the rotary disk 4 in the transmission process of the mask body. In the process of separating the ear belt, a new mask body 1 is transmitted below the rotating disc 4, the process is repeated, and the next working cycle is entered.
According to the welding device for the ear strap of the mask, the ear strap can be driven to rotate along the circumferential direction through the fixed clamping jaw and the driving motor 2, and the ear strap can be automatically segmented and fed through the shearing of the pneumatic scissors, so that the time for feeding the ear strap can be effectively reduced, the production efficiency is effectively improved, and the labor intensity is reduced; the ear strap can be welded after being segmented through the welding head 5; solves the problem of low production efficiency caused by the fact that the prior ear strap welding device needs to manually insert the ear strap.
