[0022] To address the problem of stiffness caused by rigid connections between the inner shaft and other components in existing technologies, this invention provides a reverse-drum device and a forming machine, wherein the forming machine includes the reverse-drum device described below.

[0023] like Figure 1 The illustrated inverted drum device includes an inverted drum 10, a first connecting shaft 20, a first driving member 30, and a floating device 40. The driving member is driven to the first connecting shaft 20 and drives the first connecting shaft 20 to move axially to cause the inverted drum 10 to expand and contract. The floating device 40 is located at the end of the first connecting shaft 20, and the inverted drum 10 and / or the first driving member 30 are movably connected to the first connecting shaft 20 through the floating device 40.

[0024] In this embodiment, a floating device 40 is set at the end of the first connecting shaft 20, so that the first connecting shaft 20 and the first driving member 30 are floatingly connected, and the first connecting shaft 20 and the reverse drum 10 are floatingly connected. The floating device 40 allows small axial and radial movements, thereby reducing mechanical stress and playing a certain buffering role. Thus, when the first driving member 30 drives the first connecting shaft 20 to move the reverse drum 10, it avoids the first connecting shaft 20 and the first driving member 30, and the first connecting shaft 20 and the reverse drum 10 from being constricted, which would cause damage to the reverse drum 10 and the first connecting shaft 20. This extends the service life of the reverse drum device, improves its reliability, and reduces the maintenance cost of the reverse drum device.

[0025] It should be noted that the axial direction of the embodiment refers to the axial direction of the first connecting shaft 20, that is Figure 1 the left-right direction in the figure.

[0026] In the embodiment, the floating device 40 comprises a plurality of floating members 41, and each end of the first connecting shaft 20 is provided with a floating member 41 and is drivingly connected to the reverse packing drum 10 and the first driving member 30 through the floating member 41, so that each end of the first connecting shaft 20 has a floating member 41 to disperse stress, thereby reducing the wear of the end connection of the first connecting shaft 20, prolonging the service life of the reverse packing drum 10, the first driving member 30 and the first connecting shaft 20, improving the reliability of the reverse packing drum device, reducing the downtime caused by equipment failure, and ensuring the demand for continuous production.

[0027] The floating member 41 of the embodiment is provided in two, and optionally, the floating member 41 can adopt a floating joint or a floating coupling, which can allow a certain relative displacement between two members connected thereto, and the displacement can be axial, radial or angular, thereby compensating for the centering error of the first driving member 30, the first connecting shaft 20 and the reverse packing drum 10 to a certain extent, absorbing vibration and impact, and adapting to thermal expansion and contraction, thereby improving the operation efficiency, reliability and service life of the reverse packing drum device. The floating member 41 of the embodiment allows the first connecting shaft 20 to drive the reverse packing drum 10 to complete the expansion and contraction action while avoiding the axial pressure and damage that may be caused by hard connection, and the operation is stable and safe.

When the wrapping drum 10 rotates, the floating member 41 idles relative to the first connecting shaft 20, so as to improve the flexibility of the first connecting shaft 20 and avoid the interference of the first connecting shaft 20 with other components. Specifically, when the rotating adapter 42 is connected to one side of the floating member 41 close to the wrapping drum 10, the rotation between the first connecting shaft 20 and the wrapping drum 10 does not affect each other, so that the first connecting shaft 20 and the first driving member 30 are not affected by the rotation of the wrapping drum 10, so that the first driving member 30 and the first connecting shaft 20 only have axial movement to realize the expansion and contraction of the wrapping drum 10, and do not need to rotate with the wrapping drum 10. When the rotating adapter 42 is connected to one side of the floating member 41 close to the first driving member 30, the rotation between the first connecting shaft 20 and the first driving member 30 does not affect each other, so that the first driving member 30 is not affected by the rotation of the first connecting shaft 20, so that the first driving member 30 only has axial movement to realize the expansion and contraction of the wrapping drum 10, and does not need to rotate with the first connecting shaft 20 and the wrapping drum 10, thereby improving the flexibility of the wrapping drum device. Of course, the rotating adapter 42 can also be arranged at both ends of the first connecting shaft 20, so that one or two or all of the first driving member 30, the first connecting shaft 20 and the wrapping drum 10 can rotate without affecting each other. Alternatively, the rotating adapter 42 can be a bearing, thereby allowing the relative rotation between the first connecting shaft 20 and the floating member 41.

[0029] In the embodiment, the floating member 41 between the first connecting shaft 20 and the first driving member 30 is provided with the rotating adapter 42 between the first connecting shaft 20 and the first driving member 30, so that the first driving member 30 can not be affected by the rotation of the first connecting shaft 20. Specifically, as shown in Figure 1 the first driving member 30, the floating member 41, the rotating adapter 42 and the first connecting shaft 20 are arranged in sequence, and the arrangement of the rotating adapter 42 makes the first driving member 30 free from the influence of the rotation of the first connecting shaft 20, while ensuring that the axial movement of the first connecting shaft 20 will not be affected, thereby ensuring the independence of the axial movement of the first driving member 30 driving the first connecting shaft 20, so that the driving relationship between the first driving member 30 and the first connecting shaft 20 is more reliable.

[0030] In the embodiment, the wrapping drum device further comprises a second driving member 50 and a second connecting shaft 60, the second driving member 50 is drivingly connected with the second connecting shaft 60 and drives the second connecting shaft 60 to rotate, the second connecting shaft 60 is drivingly connected with the wrapping drum 10 and drives the wrapping drum 10 to rotate, so that the rotation of the wrapping drum 10 is independent of the expansion and contraction control, the parameters in the forming process can be more flexibly adjusted, so as to improve the quality of the formed product and the production efficiency. Optionally, the second driving member 50 can adopt a synchronous pulley, which can be driven by a motor. The first driving member 30 of the embodiment adopts an electric cylinder. Of course, the first driving member 30 and the second driving member 50 can also adopt other structural forms, as long as they can realize the expansion and contraction and rotation of the wrapping drum 10.

[0031] In the embodiment, the second connecting shaft 60 is sleeved outside the first connecting shaft 20, and a gap is arranged between the inner wall of the second connecting shaft 60 and the outer wall of the first connecting shaft 20, so that the structure of the wrapping drum device is simplified, the interference between the moving parts is reduced, the wear and failure caused by the interference between the parts is reduced, the operation of the wrapping drum device is more stable, and the maintenance cost is reduced.

[0032] In the embodiment, the floating device 40 comprises a plurality of floating members 41, at least one floating member 41 is located outside the second connecting shaft 60 and at least another floating member 41 is located inside the second connecting shaft 60 along the axial direction of the first connecting shaft 20, so that on the one hand, the axial force can be more evenly distributed, the balance and stability of the device are improved, so as to ensure the precision and stability in the forming process, on the other hand, the floating member 41 located outside the second connecting shaft 60 is convenient to connect with the first driving member 30 located outside the second connecting shaft 60, so that the setting of the first driving member 30 is more flexible.

[0033] In the embodiment, the floating member 41 comprises a first floating member 41 and a second floating member 41, the first floating member 41 is located between the first driving member 30 and the first connecting shaft 20, the second floating member 41 is located between the first connecting shaft 20 and the reverse drum 10, the first floating member 41 is located outside the second connecting shaft 60, and the second floating member 41 is located inside the second connecting shaft 60, so that the rotation and expansion and contraction of the reverse drum 10 can be controlled independently and do not interfere with each other. The first floating member 41 of the embodiment is connected with the adapter 42, absorbs the stress between the first driving member 30 and the first connecting shaft 20, ensures that the first driving member 30 drives the first connecting shaft 20 to move axially, and the first driving member 30 can not be affected by the rotation of the first connecting shaft 20; the second floating member 41 is directly connected with the reverse drum 10 and the first connecting shaft 20, thereby absorbing the stress between the first connecting shaft 20 and the reverse drum 10, and the second floating member 41 can absorb the stress between the first connecting shaft 20 and the second connecting shaft 60, so as to ensure that when the second connecting shaft 60 drives the reverse drum 10 to rotate, the first connecting shaft 20 rotates with the second connecting shaft 60 without causing damage. Since the first driving member 30 does not rotate with the reverse drum 10, the first floating member 41 can be arranged outside the second connecting shaft 60 to facilitate maintenance. The first connecting shaft 20 of the embodiment rotates synchronously with the second connecting shaft 60, of course, the adapter 42 can also be arranged between the second floating member 41 and the first connecting shaft 20, so that the first connecting shaft 20 does not have to rotate with the second connecting shaft 60, thereby further improving the reliability of the reverse drum device.

[0034] In the embodiment, the reverse drum device further comprises a bearing member 70, the bearing member 70 is sleeved outside the second connecting shaft 60, so as to ensure that the rotation of the second connecting shaft 60 does not affect the external components.
