[0020] Example 1

[0021] like Figures 1-3 As shown in the figure, the adjustable cigarette paper roll support device proposed in this embodiment includes a support 1, a rotating mounting mechanism, a first driving device and a second driving device.

[0022] Two supports 1 are arranged side by side, and a telescopic adjustment device is installed between the two supports 1.

[0023] Two rotating mounting mechanisms are symmetrically arranged and mounted on supports 1 on both sides. Each rotating mounting mechanism includes a rotating housing 3, a rotating shaft 4, and two drum rotating seats 13. The rotating shaft 4 is rotatably mounted on the corresponding side support 1. The rotating housing 3 is connected to the rotating shaft 4. The two drum rotating seats 13 are slidably mounted on both sides of the rotating housing 3. Rotating holes 131 are provided on the drum rotating seats 13, and multiple second ball bearings 152 are installed inside each of the multiple rotating holes 131. A transmission assembly is installed inside the rotating housing 3. The transmission assembly includes a first gear 21, a first bevel gear 22, a second bevel gear 23, and two… Rack 19 and first gear 21 are rotatably mounted inside rotating housing 3. Both racks 19 are slidably mounted inside rotating housing 3 and mesh with first gear 21. Connecting sliders 20 are connected between the two racks 19 and the two drum rotating seats 13. Two sliding holes 301 are provided on rotating housing 3 for sliding of connecting sliders 20 on both sides. First bevel gear 22 is connected to the shaft of first gear 21. Second bevel gear 23 meshes with first bevel gear 22. Fixed shaft 24 is connected to second bevel gear 23. Fixed shaft 24 movably passes through rotating housing 3 and rotating shaft 4 and is connected to support 1.

[0024] A telescopic assembly is connected between the two rotating housings 3. The telescopic assembly includes a splined sleeve 51 and a splined shaft 52. The splined sleeve 51 and the splined shaft 52 are respectively connected to the rotating housings 3 on both sides. The end of the splined shaft 52 is slidably installed inside the splined sleeve 51.

[0025] Each of the inner walls of a plurality of drum rotating seats 13 is connected to a semi-circular ring 14, the semi-circular ring 14 being coaxially arranged with the corresponding rotating hole 131, and a plurality of first balls 151 being installed on each of the plurality of semi-circular rings 14.

[0026] The first drive device is mounted on the support 1 to drive the corresponding side rotating shaft 4 to rotate. The first drive device includes a second servo motor 10, a second gear 28 and a gear ring 29. The second servo motor 10 is mounted on the support 1. The second gear 28 is connected to the output shaft of the second servo motor 10. The gear ring 29 is disposed on the outer circumference of the rotating shaft 4 and meshes with the second gear 28.

[0027] The second drive device is mounted on the support 1 to drive the drum 2 to rotate. The second drive device includes an electric push rod 12, a movable frame 16, a third servo motor 17, a hollow cylinder 18, an insert block 25, a spring 26, and a movable plate 27. The electric push rod 12 is mounted on the support 1. The movable frame 16 is connected to the output shaft of the electric push rod 12 and moves through the support 1. The third servo motor 17 is mounted on the movable frame 16. The hollow cylinder 18 is connected to the output shaft of the third servo motor 17. The spring 26 is located inside the hollow cylinder 18. The movable plate 27 is slidably located inside the hollow cylinder 18. The insert block 25 moves through the inner and outer sides of the hollow cylinder 18 and is connected to the movable plate 27.

[0028] It should be added that a PLC controller 11 is installed on the support 1 on one side.

[0029] The installation and adjustment steps for the drum are as follows: 1. Spacing adjustment: Start the first servo motor 6 of the telescopic adjustment device, drive the threaded rod 7 to screw into / out of the threaded tube 8, and drive the two side supports 1 to move synchronously along the telescopic rod 9 to match the length of the drum 2. It has strong applicability. It should be added that, Figure 1 and Figure 2 As shown, the telescopic rod 9 includes a sleeve and a movable rod, which are respectively connected to the supports 1 on both sides. The end of the movable rod is slidably installed inside the sleeve; 2. Pre-installation of the drum: In the initial state, the two bottom drum rotating seats 13 are in a state of being far apart. The mounting shafts at both ends of the new drum are manually placed on the bottom semi-circular ring 14. At this time, the top drum is in the working position. Figure 1 state.

[0030] Support and limiting: The mounting shaft of the drum 2 is inserted into the rotating hole 131, and the second ball 152 on the inner side reduces friction; the first ball 151 on the semi-circular ring 14 constrains the axial displacement of the drum; it should be noted that lubricating oil should be dripped onto the first ball 151 and the second ball 152 at regular intervals to reduce friction.

[0031] Workstation switching: The second servo motor 10 of the first drive device drives the second gear 28, which in turn drives the gear ring 29 and the rotating shaft 4 to rotate 180°, causing the entire rotating mounting mechanism to flip.

[0032] Synchronous action: The fixed shaft 24 is fixedly connected to the support 1. During the rotation of the first bevel gear 22, it rolls on the second bevel gear 23, causing the first bevel gear 22 to rotate. The first bevel gear 22 drives the first gear 21 to rotate, which in turn drives the racks 19 on both sides to slide in opposite directions. The racks 19 push the two bottom drum rotating seats 13 toward the center through the connecting slider 20, locking the mounting shaft of the pre-installed drum into the inside of the rotating hole 131. At the same time, when the top drum rotating seat 13 rotates to the bottom, it separates, releasing the constraint on the old drum.

[0033] It should be noted that the second servo motor 10 does not continuously drive the rotating shaft 4 to rotate in one direction. When the rotating shaft 4 rotates 180° in the clockwise direction and then rotates 180° in the counterclockwise direction, its single rotation angle is 180°, and it rotates in a cyclical manner.

[0034] Disassembly of old roll 2 and installation of new roll 2: After flipping, the original top roll is lowered to the bottom, and its mounting shaft is disengaged from the rotating hole 131 and temporarily supported by the semi-circular ring 14. The old roll is then removed manually. Subsequently, the mounting shafts at both ends of the new roll 2 are placed on the two semi-circular rings 14 at the bottom.

[0035] Key mechanism coordination: the spline sleeve 51 and spline shaft 52 extend and retract when the support spacing is adjusted to ensure that the two rotating housings 3 rotate synchronously.

[0036] This technical solution adopts a dual-station setup, which allows the device to have independent pre-installation and working stations. By switching between the working and pre-installation stations by 180° rotation, the "working-pre-installation" process can be carried out in parallel. The roll changing process does not require machine downtime, and the installation of the new roll 2 and the disassembly of the old roll 2 do not require much manual intervention, which greatly improves work efficiency.

[0037] Example 2

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, this embodiment proposes an adjustable cigarette paper roll support device. Compared with Embodiment 1, in this embodiment, the second driving device includes an electric push rod 12, a movable frame 16, a third servo motor 17, a hollow cylinder 18, an insert block 25, a spring 26, and a movable plate 27. The electric push rod 12 is mounted on the support 1, the movable frame 16 is connected to the output shaft of the electric push rod 12 and movably passes through the support 1, the third servo motor 17 is mounted on the movable frame 16, the hollow cylinder 18 is connected to the output shaft of the third servo motor 17, the spring 26 is located inside the hollow cylinder 18, the movable plate 27 is slidably located inside the hollow cylinder 18, and the insert block 25 movably passes through the inner and outer sides of the hollow cylinder 18 and is connected to the movable plate 27.

[0039] The drum 2 is installed between two rotating mounting mechanisms. Both ends of the drum 2 are connected to mounting shafts, and the ends of the mounting shafts are provided with slots for inserting the plug 25.

[0040] In this embodiment, the rotation drive method for the drum is as follows: the electric push rod 12 of the second drive device pushes the moving frame 16, so that the insert 25 is inserted into the slot of the drum mounting shaft. If the insert 25 is not aligned with the slot, the spring 26 is compressed and stores energy. When the third servo motor 17 is finely rotated to the alignment, the insert 25 is automatically inserted under the action of the spring to achieve buffered insertion. Then the third servo motor 17 drives the drum to rotate.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
