They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] Please see Figure 1 , Figure 2 and Figure 3 The cigarette rotating device provided in this application embodiment will now be described. The cigarette rotating device provided in this application embodiment includes a first rotating assembly 1, which includes a first vacuum chamber 11, a first rotating shaft 12, a rotating drive component 13, and a first adsorption component 14. The first vacuum chamber 11 is connected to an external vacuum device. The first rotating shaft 12 is rotatably inserted into the first vacuum chamber 11, and a first air passage 121 communicating with the first vacuum chamber 11 is provided inside the first rotating shaft 12. The rotating drive component 13 is drively connected to the first rotating shaft 12 to drive the first rotating shaft 12 to rotate. The first adsorption component 14 is connected to the first rotating shaft 12 and is provided with a first adsorption hole 141 for adsorbing workpieces, and the first adsorption hole 141 communicates with the first air passage 121 of the first rotating shaft 12.

[0040] In the embodiments of this application, the workpiece can be a cigarette stick to be processed or other workpieces to be rotated for processing.

[0041] The rotary drive component 13 can be a rotary motor or a rotary cylinder.

[0042] The first adsorption element 14 is connected to the first vacuum chamber 11 via the first air passage 121 on the first rotating shaft 12. An external vacuum device creates a negative pressure on the first adsorption element 14 to adsorb the workpiece. The rotation drive 13 drives the first rotating shaft 12 to rotate, thereby rotating the first adsorption element 14 and thus rotating the workpiece. Since the workpiece is fixed by vacuum adsorption rather than by clamping, no pressure marks are formed on the side of the workpiece, reducing the damage rate of the workpiece.

[0043] Furthermore, the first vacuum chamber 11 does not rotate with the first rotating shaft 12, which prevents the pipes connected to the external vacuum device on the first vacuum chamber 11 from becoming entangled. Compared to using a universal joint, the embodiment of this application is more adaptable to the rotational speed of the first rotating shaft 12, while the universal joint is prone to jamming when the rotational speed is too high, causing the pipes connected to the external vacuum device to become entangled.

[0044] The first rotating assembly 1 also includes a first sealed bearing 15, which is installed in the first vacuum chamber 11 and sleeved on the first rotating shaft 12.

[0045] The first sealed bearing component 15 includes an inner ring and an outer ring, and a sealing structure is connected between the inner ring and the outer ring. The outer ring is fixed in the first vacuum chamber 11, and the inner ring is sleeved on the first rotating shaft 12.

[0046] The first sealed bearing component 15 can not only prevent air leakage at the connection between the first rotating shaft 12 and the first vacuum chamber 11, but also make the first rotating shaft 12 rotate smoothly.

[0047] The first adsorption member 14 is provided with a first limiting groove 142 for accommodating the workpiece, and the first adsorption hole 141 is provided in the first limiting groove 142.

[0048] The first limiting groove 142 can be a contour groove that matches the shape of the workpiece. The first limiting groove 142 can limit the position of the workpiece and prevent the workpiece from shifting during rotation or processing, so as to improve the processing accuracy of the workpiece.

[0049] The cigarette rotating device also includes a second rotating component 2 and a transmission component 3. The second rotating component 2 is arranged opposite to the first rotating component 1, and the second rotating component 2 is connected to the first rotating component 1 through the transmission component 3.

[0050] The cigarette rotating device also includes a mounting frame. The first rotating component 1 and the second rotating component 2 are mounted opposite each other on the mounting frame. The transmission component 3 is mounted on the mounting frame and connected to the first rotating component 1 and the second rotating component 2 respectively. The second rotating component 2 may have the same structure as the first rotating component 1.

[0051] The first rotating assembly 1 and the second rotating assembly 2 respectively adsorb both ends of the workpiece, improving the stability of the workpiece during processing. At the same time, the first rotating assembly 1 and the second rotating assembly 2 rotate both ends of the workpiece simultaneously through the transmission assembly 3, which can prevent the workpiece from generating torque and prevent the first rotating assembly 1 and the second rotating assembly 2 from rotating the workpiece asynchronously, thus reducing the damage rate of the workpiece.

[0052] The second rotating assembly 2 includes a second vacuum chamber, a second rotating shaft 22, and a second adsorption member 21. The second vacuum chamber is connected to an external vacuum device. The second rotating shaft 22 is rotatably inserted into the second vacuum chamber, and a second air passage communicating with the second vacuum chamber is provided inside the second rotating shaft 22. The second adsorption member 21 is connected to the second rotating shaft 22, and the second adsorption member 21 is provided with a second adsorption hole for adsorbing workpieces, and the second adsorption hole communicates with the second air passage of the second rotating shaft 22.

[0053] The transmission assembly 3 includes a first transmission shaft 31, which connects a first adsorption element 14 and a second adsorption element 21.

[0054] The first drive shaft 31 connects the first adsorption element 14 and the second adsorption element 21. When the first rotating shaft 12 of the first rotating assembly 1 rotates the first adsorption element 14, the second adsorption element 21 can be rotated with the first adsorption element 14 through the first drive shaft 31, so as to realize that the first adsorption element 14 and the second adsorption element 21 rotate the workpiece at the same time, prevent the workpiece from being damaged due to asynchronous rotation, and reduce the damage rate of the workpiece.

[0055] Please see Figure 1 , Figure 2 The transmission assembly 3 includes a first synchronous transmission member 32, a second synchronous transmission member 33, and a second transmission shaft 34. The first synchronous transmission member 32 is connected to the rotary drive member 13 and the first rotating shaft 12. The second synchronous transmission member 33 is connected to the second rotating shaft 22 of the second rotary assembly 2. The first synchronous transmission member 32 is connected to the second synchronous transmission member 33 through the second transmission shaft 34.

[0056] The first synchronous transmission member 32 may include a driving gear and a driven gear. The driving gear is connected to the rotary drive member 13, and the driven gear is connected to the first rotating shaft 12. The driving gear and the driven gear mesh. The second synchronous transmission member 33 may adopt the same structure as the first synchronous transmission member 32. The driving gear of the first synchronous transmission member 32 is connected to the driving gear of the second synchronous transmission member 33 via the second transmission shaft 34. The rotary drive member 13 rotates the driving gear, which simultaneously drives the first adsorption member 14 and the second adsorption member 21 via the driven gear and the second transmission shaft 34, thereby rotating the workpiece. This prevents the workpiece from being damaged due to asynchronous rotation and reduces the damage rate of the workpiece.

[0057] For preferred options, please refer to [link / reference]. Figure 1The first synchronous transmission component 32 includes a first driving wheel 321, a first driven wheel 322, and a first synchronous belt 323. The first driving wheel 321 is connected to the rotary drive component 13. The first driving wheel 321 is connected to the second synchronous transmission component 33 through the second transmission shaft 34. The first driven wheel 322 is connected to the first rotating shaft 12. The first synchronous belt 323 is sleeved on the first driving wheel 321 and the first driven wheel 322.

[0058] The second synchronous transmission member 33 can adopt the same structure as the first synchronous transmission member 32. The first driving wheel 321 of the first synchronous transmission member 32 is connected to the second driving wheel of the second synchronous transmission member 33 via the second transmission shaft 34. The second driven wheel of the second synchronous transmission member 33 is connected to the second rotating shaft 22 of the second rotating assembly 2.

[0059] The rotary drive 13 rotates the first drive wheel 321 and drives the first driven wheel 322 to rotate the first shaft 12 via the first synchronous belt 323. At the same time, the first drive wheel 321 rotates the second drive wheel via the second transmission shaft 34, causing the second driven wheel of the second synchronous transmission component 33 to rotate the second shaft 22 of the second rotating assembly 2. This causes the first adsorption component 14 and the second adsorption component 21 to rotate the workpiece simultaneously, preventing the workpiece from being damaged due to asynchronous rotation and reducing the damage rate of the workpiece.

[0060] The first synchronous transmission component 32 also includes a tension adjustment part 324, which is connected to the first synchronous belt 323 to adjust the tension of the first synchronous belt 323.

[0061] Since the first synchronous belt 323 may become loose after prolonged use, the tension adjustment part 324 can adjust the tension of the first synchronous belt 323 to prevent the first synchronous belt 323 from failing to drive the first driven pulley 322.

[0062] The tension adjustment part 324 can be an adjustment wheel installed on the mounting frame. The adjustment wheel abuts against the first synchronous belt 323 to change the circumference of the first synchronous belt 323, thereby adjusting the tension of the first synchronous belt 323.

[0063] The cigarette rotating device also includes a moving component 4, which is connected to the first rotating component 1 to drive the first rotating component 1 and the second rotating component 2 to translate.

[0064] The moving component 4 may include a horizontal moving part and a vertical moving part, which are connected by a transmission connection. The vertical moving part is also connected by a transmission connection to the first rotating component 1. The horizontal moving part may be a cylinder, an electric cylinder, or a motor, and the vertical moving part may have the same structure as the horizontal moving part.

[0065] The moving component 4 may also include only horizontal moving parts or vertical moving parts.

[0066] The moving component 4 can move the workpiece to the processing position, thereby improving production efficiency.

[0067] Please see Figure 4 This application also provides a laser processing device, including the above-mentioned cigarette rotating device.

[0068] The laser processing equipment of this application embodiment includes the cigarette rotating device in any of the above embodiments, and therefore has the beneficial effects brought by the cigarette rotating device in any of the above embodiments, which will not be repeated here.

[0069] The laser processing equipment may also include a robotic arm 5, a feeding device 6, a processing device 7, and a collecting device 8. After the robotic arm 5 picks up the workpiece from the feeding device 6, it moves the workpiece to the cigarette rotating device. The cigarette rotating device selectively rotates the workpiece according to the processing requirements. The processing device 7 performs processing steps such as drilling or engraving on the workpiece on the cigarette rotating device. After the workpiece is processed, the cigarette rotating device rotates and releases the workpiece to the collecting device 8.

[0070] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
