[0030] Embodiment one: please refer to Figures 1-5 The existing vacuum compression bag air nozzle hot melt welding mechanism is inconvenient to automatically weld around the periphery of the air nozzle, so that manual adjustment of the welding position is required during the hot melt welding process of the air nozzle, which may cause inaccurate welding position. It is inconvenient to weld different sizes of vacuum compression bag air nozzles, so that when the dimensions of the air nozzle are different, other hot melt welding devices may be required. It is inconvenient to automatically adjust the welding angle, so that the air nozzle welding position may deviate during the hot melt welding process of the air nozzle, affecting the use of the vacuum compression bag.

[0031] The eccentric rod 3 is rotatably connected to the upper end of the support frame 1, and the upper end of the eccentric rod 3 is fixedly connected to the first motor 2.

The lower end of the sliding frame 4 is slidably connected to the inner side of the arc-shaped track 8.

[0032] When the welding position needs to be automatically adjusted, the vacuum compression bag is placed above the support frame 1, and the first motor 2 is started to drive the eccentric rod 3 to rotate. With the rotation of the eccentric rod 3, the three sliding frames 4 arranged in an array on the outer side of the lower end of the eccentric rod 3 are simultaneously rotated, and the lower end of the sliding frame 4 is slidably connected to the inner side of the sliding groove 9 arranged on the inner side of the arc-shaped track 8. At this time, the upper end of the eccentric rod 3 rotates in the upper end of the support frame 1, and the main shaft continuously rotates, so that the lower end of the eccentric rod 3 continuously changes position above the arc-shaped track 8, which can automatically drive the welding head to rotate to different positions, facilitating welding of different positions of the vacuum compression bag air nozzle.
