[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. Example

[0026] Reference Figure 1-2 , which is the first embodiment of the utility model, provides a traction device for a biodegradable material film blowing machine, the traction device for a biodegradable material film blowing machine includes a bracket 1, the number of the bracket 1 is two, the inside of the bracket 1 is provided with an adjusting component 2, and the adjusting component 2 passes through the top end of the bracket 1, and the upper side of the bracket 1 is provided with a mounting component 3.

[0027] The adjusting component 2 includes a herringbone splint 21 hinged on the opposite surfaces of the two brackets 1, two first electric push rods 22 are hinged on the inner side of the two brackets 1 through a pin shaft, and the other ends of the two first electric push rods 22 are hinged on the corresponding side of the herringbone splint 21 through a pin shaft. The top end of the bracket 1 and the bottom end of the mounting plate 23 overlap each other, and the top end of the mounting plate 23 is provided with a through hole 24. The top ends of the two mounting plates 23 are provided with movable grooves 25. The insides of the two movable grooves 25 are slidably connected with push plates 26. The top ends of the two push plates 26 are fixedly connected to the bottom end of the same mounting plate 23, and the inner side of the movable groove 25 is fixedly connected to two second electric push rods 27, and the other ends of the two second electric push rods 27 are fixedly connected to the corresponding side of the same push plate 26.

[0028] The bracket 1 is in an “L” shape, and the shape of the movable groove 25 matches the shape of the push plate 26 .

[0029] During use, since the two ends of the first electric push rod 22 are respectively connected to the bracket 1 and the herringbone splint 21 through a pin shaft, when the first electric push rod 22 is started, the angle of the herringbone splint 21 will change. When the spacing of the herringbone splint 21 needs to be adjusted, the second electric push rod 27 fixed to one side of the push plate 26 under the mounting plate 23 can be started. Since the push plate 26 is inside the movable groove 25, when the second electric push rod 27 is started, the second electric push rod 27 will push or pull the side wall of the movable groove 25, so that the two brackets 1 will be under the mounting plate 23 and drive the herringbone splints 21 to move closer or farther away, which is convenient for adjusting the angle of the herringbone splints 21. At the same time, the gap between the herringbone splints 21 can also be quickly adjusted, so that the herringbone splints 21 can be suitable for the processing of products of different models, avoiding repeated disassembly of the herringbone splints 21. Example

Traction rollers 37 are provided on the opposite surfaces of the two connecting plates 36. Two guide grooves 35 are provided at the top end of the mounting plate 23. The two guide grooves 35 are respectively connected to the movable groove 25. The outer surface of the connecting plate 36 is slidably connected in the guide groove 35. The shape of the guide groove 35 is adapted to the shape of the connecting plate 36.

[0032] During use, as the bracket 1 moves under the mounting plate 23, the slider 34 fixed on the top of the bracket 1 will slide in the slide groove 33 under the mounting plate 23, and at the same time, the connecting plate 36 fixed inside the movable groove 25 will penetrate the mounting plate 23 through the guide groove 35, and drive the two traction rollers 37 to adjust their positions. When assembling the mounting plate 23, the mounting plate 23 can be docked with the external film blowing machine through the mounting ears 31 on both sides thereof, and the two can be locked by bolts 32, which facilitates the adjustment of the herringbone splint 21 while also allowing the synchronous adjustment of the traction roller 37 that is the same as the traction product. It also facilitates the assembly of the mounting plate 23 with the external film blowing machine to improve the flexibility of the mounting plate 23.
