[0017] According to Figures 1-5 As shown in the figure, a double-cylinder roller device of a slitting machine includes wall plates 1, between which are arranged two sets of winding devices 2, and the wall plates 1 are further provided with lifting devices 3 for lifting the winding shafts to prevent them from being damaged due to being suspended; the lifting device 3 includes a connecting plate 31 arranged at the front end of the wall plate 1 through a linear guide rail 32, the connecting plate 31 being the main load-bearing part of the lifting device 3 and being capable of moving up and down along the linear guide rail 32, the connecting plate 31 being provided at the front end with two sets of cantilevers 33 arranged above and below, the cantilevers 33 being provided with brackets 34, the brackets being provided with telescopic cylinders 35 and supporting plates 36, the supporting plates 36 being used for lifting the winding shafts, the supporting plates 36 being provided with guide rails 37 between the supporting plates 36 and the brackets 34, the movable end of the telescopic cylinder 35 being connected with the supporting plate 36, the telescopic cylinder 35 being used for driving the supporting plate 36 to move forward and backward to adapt to the moving track of the winding shafts during transposition, the rear end of the connecting plate 31 being provided with a connecting arm 38, the connecting arm 38 being connected with a lifting device 4 for providing power for lifting the connecting plate 31; the lifting device 4 is arranged outside the wall plate 1, and the lifting device 4 includes a first cylinder 41, a second cylinder 42, a lifting plate 43 and a base 44, the base 44 being arranged at the bottom of the wall plate 1, the first cylinder 41 and the second cylinder 42 being arranged on the lifting plate 43, the movable end of the first cylinder 41 being arranged upward and connected with the connecting arm 38, the movable end of the second cylinder 42 being arranged downward, the movable end penetrating through the lifting plate 43 and being connected with the base 44, the first cylinder 41 and the second cylinder 42 being capable of controlling the connecting plate 31 to be lifted in two stages, the second cylinder 42 being capable of controlling the lifting plate 43 and the first cylinder 41 to be lifted integrally to indirectly lift the connecting plate 31 in the first stage, and the first cylinder 41 being capable of directly lifting the connecting plate 31 in the second stage.

[0018] The winding device 2 includes a transposition device 21, the transposition device 21 being provided with a first winding shaft 22 and a second winding shaft 23, and the supporting plates 36 on the two sets of cantilevers 33 arranged above and below are arranged at the bottom of the first winding shaft 22 and the second winding shaft 23.

[0019] The wall plate 1 is further provided with a rotary unloading device 5 near the lifting device 3.

[0020] In the practical process, in the initial state, the first winding shaft 22 is located in the winding station, ready to start winding the material, at this time, the supporting plate 36 of the lifting device 3 is located below the first winding shaft 22, when the first winding shaft 22 starts to wind, the second cylinder 42 starts to lift the connecting plate 31 by the first section, so that the supporting plate 36 can move to the bottom of the first winding shaft 22, and the passive lifting is carried out. During the lifting process, the weight of the winding material on the first winding shaft 22 after winding is calculated in advance, and then the cylinder continuously provides the corresponding force during winding, so as to offset the weight of the winding material by this passive lifting method.

[0021] When the winding of the winding material on the first winding shaft 22 is completed, the position changing device 21 starts to exchange positions with the second winding shaft 23, and the first winding shaft 22 moves along a circular track and is ready to transfer to the unloading station. During the position changing process, the first cylinder 41 starts to drive the connecting plate 31 to lift by the second section, so that the supporting plate 36 can lift along the moving track of the first winding shaft 22, to ensure that the lifting device 3 can continuously and effectively support the first winding shaft 22 during the whole position changing process. With the movement of the first winding shaft 22, the first winding shaft 22 gradually separates from the supporting plate 36. In order to maintain the lifting state, the telescopic cylinder 35 starts to push the supporting plate 36 to move forward, to ensure that the first winding shaft 22 is always in the lifting state during the whole position changing process. Then, under the support of the lifting device 3, the first winding shaft 22 reaches the unloading station and performs the unloading operation.

[0022] When the first winding shaft 22 reaches the unloading station, the winding material is transferred from the first winding shaft 22 to the rotating unloading device 5. In order to ensure that the winding material can pass smoothly, the second cylinder 42 starts to retract, to lower the height of the supporting plate 36, so that the winding material can be smoothly transferred from the first winding shaft 22 to the rotating unloading device 5, to complete the unloading operation. When the second cylinder 42 retracts, the telescopic cylinder 35 also starts to retract, to return the supporting plate 36 to the initial position, at the bottom of the second winding shaft 23 in the winding station, and then the second cylinder 42 starts again for the next lifting operation.

[0023] The design scheme is ingenious, which uses simple mechanical structures such as the first cylinder and the second cylinder, to provide a low-cost lifting device. Compared with the traditional servo pusher and servo motor, the manufacturing cost of the equipment is significantly reduced. The lifting device can effectively follow the moving track of the winding shaft during winding or during position changing, to prevent damage due to excessive weight of the winding material, and to improve the safety of the equipment. The lifting device can also ensure that the winding material is smoothly transferred from the winding shaft to the rotating unloading device.

[0024] The present application is not limited to the foregoing specific embodiments. The present application extends to any new feature or combination of features disclosed in this specification, as well as any new method or process disclosed in this specification or any new combination of steps of the disclosed methods or processes.
