[0004] However, there is a certain gap at the connection between the air shaft and the support rod, which may cause the small rolls after cutting to fall off during the transfer from the air shaft to the support rod, thus greatly increasing the risk of accidental damage. Secondly, during the docking process of the air shaft and the support rod, it is not convenient to horizontally adjust the support rod to be closely attached to one end of the air shaft, and thus it is not convenient to horizontally adjust the position of the support rod, further reducing the flexibility of adjusting the unloading area.

[0005] It can be seen that the existing technology still needs to be improved. Content of the Utility Model

[0031] The docking structure 4 includes a support rod 41. The right end of the support rod 41 is adapted to the left end of the air shaft 2. One end of the support rod 41 is in close contact with the end of the air shaft 2 away from the frame 1. A sleeve 42 is fixedly connected to the end of the support rod 41 away from the air shaft 2. A vertical rod 43 is fitted and connected inside the sleeve 42. When the support rod 41 is docked with the air shaft 2, the included angle between the vertical rod 43 and the support rod 41 is 90°. A bottom plate 45 is fixedly connected to the bottom of the vertical rod 43, and the bottom plate 45 is located at the center of the bottom of the vertical rod 43;

[0032] The pushing structure 5 includes a base 51. A pushing cylinder 52 is hinged to one side of the top of the base 51. The pushing cylinder 52 is located on the right side of the bottom plate 45. A telescopic end of the pushing cylinder 52 is fixedly connected to an adjustment block 53. The adjustment block 53 is hinged to the bottom plate 45. A strip-shaped slide plate 54 is fixedly connected to the bottom of the bottom plate 45. There are two strip-shaped slide plates 54, and the two strip-shaped slide plates 54 are symmetrically distributed with the central axis of the bottom plate 45 as the center. A guide rail 55 is fixedly connected to the top of the base 51. The guide rail 55 is slidably connected to the strip-shaped slide plate 54. After the limit on the end of the air shaft 2 away from the frame 1 is cancelled by the limit structure 3, the small rolls of packaging film cut on the air shaft 2 move horizontally to the left, so that all the small rolls on the air shaft 2 move onto the support rod 41. The pushing cylinder 52 operates, and the adjustment block 53 pushes the bottom plate 45 to move. The strip-shaped slide plate 54 and the guide rail 55 make the bottom plate 45 move stably, so that the support rod 41 and the air shaft 2 move to be separated. Then, the angle of the support rod 41 is adjusted to assist the blanking process of the small rolls of packaging film, thereby increasing the safety of the blanking of the small rolls after the packaging film is cut.

[0033] Please refer to Figures 1 - 2 , the pushing cylinder 52, the adjustment block 53 and the bottom plate 45 are all arranged on the central axis of the top of the base 51, which is convenient for the pushing cylinder 52 to push the bottom plate 45 to move horizontally, so that the support rod 41 moves horizontally to be separated from the air shaft 2.

[0034] Please refer to Figure 2 , there are two guide rails 55, and the two guide rails 55 are symmetrically distributed with the central axis of the base 51 as the center. The number of the guide rails 55 is equal to that of the strip-shaped slide plates 54, which increases the stability of the movement of the bottom plate 45.

[0035] Please refer to Figures 2 - 3 , a support disc 44 is attached to the bottom of the sleeve 42. There are two support discs 44, and the two support discs 44 are distributed up and down on the outer side wall of the vertical rod 43. The support disc 44, the sleeve 42 and the vertical rod 43 are coaxial. The support disc 44 is slidably connected to the vertical rod 43, and the support disc 44 supports the sleeve 42.

[0036] Please refer to Figure 3, a bolt 46 is threadedly connected to the support plate 44. Four bolts 46 are arranged in a circumferential array on each support plate 44. A threaded hole 47 is formed in the vertical rod 43, and the threaded hole 47 is adapted to the bolt 46. The bolt 46 and the threaded hole 47 position and fix the adjusted position of the support plate 44, facilitating the docking of the support rod 41 with the air shaft 2 at different heights.

[0037] Please refer to Figure 4 , the limiting structure 3 includes a support bracket 31 slidably connected inside the frame 1. A limiting cylinder 33 is fixedly connected to the support bracket 31, and the limiting cylinder 33 limits the end of the air shaft 2 away from the frame 1.

[0038] Please refer to Figure 4 , a card slot 32 is formed in the support bracket 31. There are two card slots 32, and the two card slots 32 are symmetrically distributed with the central axis of the support bracket 31 as the center. The air shaft 2 passes through the support bracket 31 through the card slot 32, and the card slot 32 facilitates the air shaft 2 to pass through the support bracket 31.

[0039] Please refer to Figure 4 , a hydraulic rod 34 is fixedly connected inside the frame 1. The telescopic end of the hydraulic rod 34 is fixedly connected to the support bracket 31. After the hydraulic rod 34 operates, the position of the support bracket 31 is adjusted, thereby facilitating the limitation of the end of the air shaft 2 away from the frame 1.

[0040] Working principle: When it is necessary to unload the packaging film cut into multiple small rolls from the air shaft 2, the limiting cylinder 33 operates first, and then the hydraulic rod 34 operates to adjust the position of the support bracket 31, so that the support bracket 31 moves to separate from the end of the air shaft 2 away from the frame 1. Since the air shaft 2 and the support rod 41 are in a coaxial state, then the small rolls on the air shaft 2 are sequentially moved in the direction close to the support rod 41, so that the small rolls on the air shaft 2 are transferred to the support rod 41. The pushing cylinder 52 operates, and the bottom plate 45 is moved in the direction away from the pushing cylinder 52 through the adjusting block 53. The strip-shaped slide plate 54 and the guide rail 55 increase the stability of the movement of the bottom plate 45, so that the end of the support rod 41 away from the sleeve 42 moves to separate from the end of the air shaft 2 away from the frame 1. The angle of the support rod 41 is adjusted through the sleeve 42, the vertical rod 43 and the support plate 44, and then the small roll on the support rod 41 can be moved to the transport rack;

[0041] When it is necessary to adjust the position of the support rod 41, the positions of the sleeve 42 and the support plate 44 are vertically adjusted through the vertical rod 43, and then the position of the support plate 44 after adjustment is limited through the bolt 46 and the threaded hole 47, facilitating the docking of the support rod 41 with the air shaft 2 at different heights.
