The V-shaped support 38 is provided with a plum handle bolt 39 for locking the ball bearing 17. A driven gear 15 is coaxially arranged at one shaft end of the air-expanding shaft 17.

The supporting plate 18 is arranged at the left end of the front side of the electric control box 1, the reduction motor 19 is arranged on the supporting plate 18, and its shaft end is coaxially connected to the driving pulley 20, and the driven pulley 21 is mounted on the supporting plate 18. The driving pulley 20 is driven and connected to the driven pulley 21 through the synchronous belt 22, and the driven pulley 21 is concentrically connected to the left turntable 24. Two centrally symmetrical positioning slots 30 are eccentrically provided on the right end surface of the left turntable 24.

The left end of the pull rod 26 is concentrically connected to the right turntable 25, and the right turntable 25 is concentric with the left turntable 24. An annular guide groove 31 is concentrically provided on the left end surface of the right turntable 25, and the right ends of the two cross bars of the H-type coil rack 23 are inserted into the annular guide groove 31. A reset spring 29 is sleeved on the pull rod 26 and is located between the right turntable 25 and the linear bearing 28. A cover body 32 is also provided on the support plate 18. The pull rod 26 is held and pulled horizontally to the right side, driving the right turntable 25 to overcome the resistance of the reset spring 29 and move right, so that the annular guide groove 31 on the right turntable 25 is separated from the right end of the H-type coil rack 23, thereby facilitating the left end of the H-type coil rack 23 to be pulled out from the positioning slot 30, and then it can be convenient to extract the unloading roll from the H-type coil rack 23.

[0034] Specifically, the electric control box 1 is provided with a bag holding mechanism located between the main body and the winding material mechanism, such as Figure 6As shown, the bag holding mechanism includes a bag holding plate 33 and an electric telescopic rod 34. The bag holding plate 33 is used to hold the inflated air column bag for the winding mechanism to wind and collect the material. The upper edge of the bag holding plate 33 is provided with a hinge 35 hinged to the front side of the electric control box 1, and the lower end surface of the bag holding plate 33 is provided with a hinge seat 36. The electric telescopic rod 34 is arranged inside the electric control box 1, and its fixed end is hinged inside the electric control box 1, and its telescopic end passes through the front side of the electric control box 1 and is movably connected to the hinge seat 36 through a fisheye joint 37. The bag holding plate 33 is driven by the electric telescopic rod 34 to rise and approach the H-shaped coil rack 23 of the winding mechanism, and the air bag column is moved from the two sets of inflators 2 After the air comes out of the inflated outlet, it is supported on the upper end surface of the raised bag supporting plate 33, and then the head of the air column bag is manually inserted between the two cross bars of the H-shaped coil rack 23, and the winding is started by the drive of the reduction motor 19, and the bag supporting plate 33 always keeps a lifted state. As the diameter of the wound roll on the H-shaped coil rack 23 increases, the bag supporting plate 33 is driven by the electric telescopic rod 34 and gradually swings down to reduce the height. Because the bag supporting plate 33 always keeps a lifted state, the air bag column is always subjected to a supporting force. Therefore, the air column bag can be subjected to a certain tension when winding, thereby reducing the gap between the winding layers of the roll and maintaining the winding effect of the roll.

[0035] Working principle: Through two groups of inflators 2, the air column bag can be inflated on both sides, which increases the inflation speed of the air column bag and saves production time; through the compatible adjustment mechanism, the distance between the two groups of inflators can be adjusted horizontally, and various air column bag sizes can be compatible for inflation; through the winding mechanism, automatic material collection is realized.
