[0028] On the one hand, please refer to Figures 1 to 3 This embodiment provides a tobacco stack film peeling device for peeling the film between the tobacco stack 13 and the conveyor belt 10. The tobacco stack film peeling device includes a driving component 1, a winding rod 2, a first connecting plate 3, and a second connecting plate 4. The first connecting plate 3 and the second connecting plate 4 are connected to the frame 11 to be connected, and are arranged opposite to each other. The winding rod 2 is rotatably connected between the first connecting plate 3 and the second connecting plate 4. The winding rod 2 is connected to one end of the film to be peeled and can wrap the film to be peeled. The driving component 1 is rotatably connected to the first connecting plate 3 and is drivenly connected to the winding rod 2, and can drive the winding rod 2 to rotate. With this configuration, by connecting one end of the film at the bottom of the tobacco stack 13 to the winding rod 2 and driving the winding rod 2 to rotate, the film is wrapped around the winding rod 2, thereby peeling off the film at the bottom of the tobacco stack 13. There is no need to manually adjust the position of the tobacco stack 13 to expose the film at the bottom of the tobacco stack 13, which can reduce the labor intensity of workers and improve the film peeling efficiency.

[0029] Specifically, the driving component 1 is a handwheel. By turning the handwheel counterclockwise, the operator can cause the winding rod 2 to rotate counterclockwise around its axis, thus peeling off the film from the bottom of the tobacco stack 13. After the film is peeled off, turning the handwheel clockwise causes the winding rod 2 to rotate clockwise around its axis, separating the peeled film from the winding rod 2 for easy recycling. In other embodiments, the driving component 1 can also be a motor.

[0030] Alternatively, please refer to Figure 1 The tobacco stack film peeling device also includes a drive shaft 5 and a transmission assembly 7. One end of the drive shaft 5 is connected to the drive member 1, and the other end of the drive shaft 5 passes through the first connecting plate 3 and is connected to the input end of the transmission assembly 7. The output end of the transmission assembly 7 is connected to the winding rod 2. Preferably, the drive shaft 5 and the winding rod 2 are arranged parallel to each other. This arrangement helps to achieve a compact design of the device, saves space, and facilitates the integration of the tobacco stack film peeling device into the tobacco stack film peeling platform. At the same time, the power of the drive member 1 is transmitted to the winding rod 2 through the drive shaft 5 and the transmission assembly 7, which has high transmission efficiency and enables the winding rod 2 to rotate, thereby winding the film to be peeled and achieving effective peeling of the film at the bottom of the tobacco stack.

[0031] Specifically, please refer to Figure 1 and Figure 2 The transmission assembly 7 includes a driving pulley 71, a driven pulley 72, and a synchronous belt 73. The driving pulley 71 is coaxially arranged with and driven by the drive shaft 5. The driven pulley 72 is driven by the driving pulley 71 via the synchronous belt 73, and the driven pulley 72 is driven by the winding rod 2. The synchronous belt 73 is a toothed synchronous belt to prevent slippage. In some embodiments, the transmission assembly 7 also includes a tensioning device. The synchronous belt 73 has the advantages of high transmission efficiency and low noise. It transmits the power of the driving member 1 to the winding rod 2 through the drive shaft 5, the driving pulley 71, the driven pulley 72, and the synchronous belt 73, thereby improving the transmission efficiency of the device. In other embodiments, the transmission assembly 7 can also be a gearbox.

[0032] Alternatively, please refer to Figure 2 The tobacco stack film peeling device also includes a fixed base 6 and a first bearing 8. The fixed base 6 is fixedly connected to the first connecting plate 3. The drive shaft 5 passes through the fixed base 6 and the first connecting plate 3 in sequence. The outer ring of the first bearing 8 is fixedly embedded in the fixed base 6, and the inner ring of the first bearing 8 is fixedly sleeved on the drive shaft 5. The inner ring of the first bearing 8 can rotate relative to the outer ring of the first bearing 8 around the axis of the drive shaft 5. With this configuration, the fixed base 6 is fixedly connected to the first connecting plate 3, and the outer ring of the first bearing 8 is fixedly embedded in the fixed base 6, so that the first bearing 8 is located within the space enclosed by the fixed base 6 and the first connecting plate 3. This prevents the first bearing 8 from moving along the axis of the drive shaft 5, improving the stability of the system. At the same time, the inner ring of the first bearing 8 is fixedly sleeved on the drive shaft 5, and the inner ring of the first bearing 8 can rotate relative to the outer ring of the first bearing 8 around the axis of the drive shaft 5, reducing the friction between the fixed base 6 and the drive shaft 5 and improving the transmission efficiency of the device.

[0033] Preferably, the first bearing 8 is a deep groove ball bearing, which has a high radial load capacity, further improving the reliability of the device. In other embodiments, the first bearing 8 may also be a cylindrical roller bearing, a thrust ball bearing, etc.

[0034] Alternatively, please refer to Figure 2The tobacco stack film peeling device also includes two second bearings 9. The inner rings of the two second bearings 9 are fixedly sleeved at both ends along the axis of the winding rod 2. The outer ring of one second bearing 9 is fixedly embedded in the first connecting plate 3, and the inner ring of the other second bearing 9 is fixedly embedded in the second connecting plate 4. The inner rings of the two second bearings 9 can rotate relative to the outer rings of the two second bearings 9 around the axis of the winding rod 2. This arrangement reduces the friction between the winding rod 2 and the first connecting plate 3, and between the winding rod 2 and the second connecting plate 4, allowing the winding rod 2 to rotate reliably and stably between the first connecting plate 3 and the second connecting plate 4. This ensures that the film at the bottom of the tobacco stack 13 can be wound onto the winding rod 2, thus achieving film peeling.

[0035] Preferably, the second bearing 9 is a self-aligning roller bearing. By setting the second bearing 9 to a self-aligning roller bearing, the position of the winding rod 2 can be finely adjusted, facilitating the assembly of the winding rod 2 and ensuring that the winding rod 2 can rotate stably between the first connecting plate 3 and the second connecting plate 4, thus ensuring the stable operation of the tobacco stack film peeling device. In other embodiments, the second bearing 9 can also be a self-aligning ball bearing.

[0036] Optionally, the handwheel is provided with an anti-slip layer. Specifically, the anti-slip layer is a rubber layer, which makes it easier for the operator to turn the handwheel.

[0037] Optionally, an anti-slip layer is provided on the contact surface between the winding rod 2 and the film. Specifically, the anti-slip layer is a rubber layer. This configuration increases the friction between the winding rod 2 and the film to be peeled, preventing the film from slipping off the winding rod 2 and improving the reliability of the tobacco stack film peeling device.

[0038] On the other hand, please refer to Figure 3 This embodiment provides a tobacco stack film peeling platform, which includes a conveyor belt 10, a frame 11 to be connected, a positioning device 12, and the aforementioned tobacco stack film peeling device. The conveyor belt 10 is disposed on the frame 11 to be connected and is used to support and transport tobacco stacks 13. A peeling station is provided on the conveyor belt 10, and a winding rod 2 is disposed at the peeling station on the conveyor belt 10, with the length direction of the winding rod 2 perpendicular to the transport direction of the conveyor belt 10. The positioning device 12 is used to detect the position of the tobacco stack 13. Specifically, the positioning device 12 is a photoelectric sensor, disposed on the extension line of the axis of the winding rod 2. In other embodiments, the positioning device 12 can also be an infrared sensor, a radio frequency identification device, etc.

[0039] The steps for peeling the packaging film off the tobacco stack 13 using the tobacco stack film peeling platform are as follows:

[0040] S1: The tobacco stack 13 is conveyed to the stripping station via the conveyor belt 10, triggering the photoelectric sensor and prompting the operator to perform the operation;

[0041] S2: The operator cuts off and peels off the film from the four side walls and the top of the smoke stack 13;

[0042] S3: Use tape to fix one end of the film at the bottom of the smoke stack 13 to the winding rod 2;

[0043] S4: Turn the handwheel counterclockwise, and drive the winding rod 2 to rotate counterclockwise through the transmission shaft 5 and the transmission assembly 7, so that the film is wound on the winding rod 2. At the same time, the conveyor belt 10 drives the smoke stack 13 away from the peeling station.

[0044] S5: After the film at the bottom of the smoke stack 13 is completely peeled off, turn the handwheel clockwise to make the winding rod 2 rotate clockwise, separate the film wrapped on the winding rod 2 from the winding rod 2, and recycle the film.

[0045] The packaging film of the tobacco stack 13 is peeled off by the tobacco stack film peeling platform. Compared with manual tearing, the film residue rate at the bottom of the tobacco stack 13 is reduced. During the operation, there is no need to manually adjust the position of the tobacco stack 13 to expose the film at the bottom of the tobacco stack 13, which can reduce the labor intensity of workers and improve the film peeling efficiency. After peeling, the peeled film can be effectively collected, avoiding the risk of the film scattering and getting stuck in the machine.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
