The material changing assembly 34 in this embodiment is rotatably connected to the roller on the loading frame 31. The material of the ear band wire is loaded to ensure the smoothness of the subsequent transmission shaping.

[0045] Continue to refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 , Figure 7It is another structural schematic diagram of the mask ear strap transmission shaping mechanism and the welding drive mechanism in this embodiment. Furthermore, the welding drive mechanism 6 includes a welding drive assembly 61, a reset guide assembly 62 and a welding block assembly 63. The welding drive assembly 61 is connected to the welding block assembly 63 through the reset guide assembly 62. The welding drive assembly 61 drives the welding block assembly 63, and the welding block assembly 63 is pressed on the head of the ear strap. The welding mechanism 2 welds the head of the ear strap to the mask body, and the reset guide assembly 62 resets the welding block assembly 63 after welding. The welding drive mechanism 6 is arranged on the mounting frame 20, which is located between the clamping drive assembly 43 and the discharge drive assembly 45. Specifically, the number of the reset guide assembly 62 is two, and the welding block assembly 63 has two welding blocks. The welding drive assembly 61 in this embodiment is arranged on the mounting frame 20, and its output end is respectively connected to one end of two reset guide assemblies 62 through the driving connecting plate 611, and the other ends of the two reset guide assemblies 62 are respectively connected to two welding blocks of the welding block assembly 63 after passing through the transmission bearing frame 41, and the welding blocks of the welding block assembly 63 are directly opposite to the middle part of the two clamping parts 4231 arranged side by side.

After the cutting mechanism 5 completes cutting, the welding drive assembly 61 in this embodiment drives the reset guide post of the reset guide assembly 62 to descend, thereby driving the welding pressure block of the welding pressure block assembly 63 to press the cut head onto the mask body on the supporting plate 121. At this time, the reset spring is compressed, and the welding mechanism 2 completes ultrasonic welding to achieve welding of the ear straps, and then the welding pressure block assembly 63 is reset under the reverse force of the reset spring.

[0046] The transmission shaping and welding process in this embodiment is as follows: For ease of understanding, the four clamping parts 4231 are defined as clamping part a, clamping part b, clamping part c and clamping part d, wherein clamping part a and clamping part b are two clamping parts arranged side by side between the two shaping limit members 222, clamping part c and clamping part d are the other two clamping parts arranged side by side between the two shaping limit members 222, and clamping part a and clamping part d are arranged diagonally.

[0047] Initially, the a clamping part and the b clamping part are located below the two clamping rams 433. The ear band wire material fed by the wire feeding mechanism 3 is connected to the clamping end of the a clamping part through the feeding assembly 46. Then the clamping drive 431 drives the clamping ram 433 to press down on the clamping ends of the a clamping part and the b clamping part, so that the a clamping part and the b clamping part rotate, and the clamping end presses the head of the ear band wire material on the clamping pressing block 42121. The clamping ram 433 retracts after completing the clamping, and the head is fixed in the a clamping part. Then, the rotary drive 441 drives the rotary drive column 442 to rotate 180 degrees, and drives the transmission shaping assembly 42 to rotate 180 degrees, so that the ear band wire material is wound in the limit groove 4221 of the shaping limiter 422 between the a clamping part and the c clamping part, and continues to pass through the c clamping part and extends to the diagonal d clamping part. At this time, the c clamping part and the d clamping part are below the two clamping heads 433, and then the clamping head 433 presses down so that the c clamping part and the d clamping part are in a clamping state. In this way, the shaping limiter 422 completes the transmission shaping of the ear band wire. Then, the cutting drive assembly 51 drives the cutting head assembly 52 to approach the ear band wire between the c clamping part and the d clamping part, and the cutting head assembly 52 cuts off the ear band wire between the c clamping part and the d clamping part, and cuts out another head to form the ear band. Afterwards, the welding drive assembly 61 drives the welding block assembly 63 to press down on the two heads of the cut ear band to the mask body, and the welding mechanism 2 performs ultrasonic welding to complete the mask welding. Afterwards, the discharge driving member 451 drives the discharge pressing head 453 to press down on the discharge ends of the clamping part a and the clamping part b, so that the clamping part a and the clamping part b are reset, and at the same time, the ear band is withdrawn from the shaping limiter 422 through the belt pushing member 454.

[0048] Continue to rotate so that the subsequent ear strap wire is wound around the shaping limiter 422 between the d clamping part and the b clamping part, and extends through the b clamping part to the a clamping part, and repeat the above process to cut and weld the ear straps of the next mask body. In this way, by relatively arranging two mask ear strap welding devices in this embodiment, the welding of the two ear straps of the mask body can be completed, which is efficient and quick.
