A strip angle steel is fixedly installed on the base, and a rack is arranged on one side of the strip angle steel. 12, and the other side is connected with the roller 13 as a guide rail, that is, the first drive motor 14 drives the driving gear 10 to rotate, and the driving gear 10 meshes with the rack 12 to drive the first motion platform 7 to reciprocate along the strip angle steel. The first drive motor 14 can be a conventional servo motor. The first drive motor 14 is fixedly installed at the lower end of the first motion platform 7 by bolt connection. The first drive motor 14 drives the first motion platform 7 to move relatively close to or away from the winding device 1 in the horizontal direction by meshing with the driving gear 10 through the rack 12. The first motion platform 7 is provided with a second motion platform 15 Specifically, the second motion platform 15 is connected to the first motion platform 7 through a second driving assembly 6. The second driving assembly 6 includes a sliding guide rail arranged on the first motion platform 7 and a slider arranged at the lower end of the second motion platform 15. The slider is matched with the sliding guide rail. An electric push rod 16 is arranged between the first motion platform 7 and the second motion platform 15. One end of the electric push rod 16 is fixedly installed or hinged on the first motion platform 7, and the other end can be fixedly installed or hinged on the second motion platform 15. The second motion platform 15 is driven by the electric push rod 16 to move along the sliding guide rail. The humidifying device is fixedly mounted on the second moving platform 15, and the output end of the humidifying device is aligned with the reeling device 1 or the cigarette tipping paper 22. The humidifying device is quickly approached to the reeling device 1 through the first moving platform 7, and the position of the first moving platform 7 relative to the base can be fixed by meshing the rack 12 with the driving gear 10. The humidifying device is accurately moved relative to the reeling device 1 or the cigarette tipping paper 22 through the second moving platform 15, ensuring that the distance between the output end of the humidifying device and the cigarette tipping paper 22 is kept constant, thereby ensuring the humidification effect and stability;A guide assembly is provided at the output end of the humidifier, and the guide assembly includes a guide plate 3, and the guide plate 3 is connected to a swing drive mechanism 4, and the swing drive mechanism 4 can drive the guide plate 3 to rotate relative to the winding device 1. Specifically, the swing drive mechanism 4 can be a conventional servo motor that can rotate forward and backward, which can be connected to the guide plate 3 through a rotating shaft, and the rotating shaft can be set at a position between the middle of the guide plate 3 and one end close to the humidifier. The swing drive mechanism 4 drives the guide plate 3 to swing along the axis of the rotating shaft through the rotating shaft, and the atomized particles generated by the humidifier can be guided to the cigarette plugging paper 22 through the guide assembly to ensure uniform humidification and improve the quality and stability of humidification; in some other embodiments, the swing drive mechanism 4 adopts a conventional electric push rod, wherein one end of the swing drive mechanism 4 is fixed or hinged on the base or the outer surface of the humidifier, and the other end is hinged on the guide plate 3 close to the winding device 1. ;

[0024] In some embodiments, the humidifying device further includes a control component, and a first sensing component 21 is provided at the output end of the humidifying device, and the first sensing component 21 is electrically connected to the control component, and the first sensing component 21 is used to detect the distance between the humidifying device and the winding device 1. Specifically, the control component can adopt conventional models and structures in the industry, which usually includes a programmable controller, and the first sensing component 21 can be a photoelectric sensor. After the first driving component drives the humidifying device to a certain distance from the winding device 1 through the first moving platform 7, the photoelectric sensor senses the cigarette wrapping paper 22 on the winding device 1 and sends a sensing signal to the control component, and the control component controls the first driving component to stop moving, thereby avoiding the humidifying device from colliding with or interfering with the winding device 1, affecting the stability of the equipment operation; and the distance of the humidifying device relative to the winding device 1 can be controlled according to the power of the humidifying device and the actual usage, thereby improving the applicability of the humidifying device.

[0025] In some embodiments, reference Figure 5As shown, a second sensing component 2 is provided on one end of the guide plate 3 near the cigarette tipping paper 22. The second sensing component 2 is electrically connected to the control component. The second sensing component 2 can adopt a conventional photoelectric sensor. The second sensing component 2 is used to detect the distance between the guide plate 3 and the cigarette tipping paper 22. Specifically, the distance between the guide plate 3 or the humidifying device and the cigarette tipping paper 22 can be set to a certain range value. The distance between the guide plate 3 or the humidifying device and the cigarette tipping paper 22 can be detected by the second sensing component 2. If the actual detection distance is less than the set distance, the distance between the guide plate 3 or the humidifying device and the cigarette tipping paper 22 can be detected by the second sensing component 2. If the actual detection distance is greater than the set distance, the control component can drive the humidifying device to move away from the cigarette tipping paper 22 through the second driving component 6. If the actual detection distance is greater than the set distance, the control component drives the humidifying device to move closer to the cigarette tipping paper 22 through the second driving component 6, so that the distance between the output end of the humidifying device and the winding surface of the cigarette tipping paper 22 is within a certain range, thereby achieving online real-time humidification, ensuring that the cigarette tipping paper 22 can be stably humidified, and ensuring that the lateral contraction of the cigarette tipping paper 22 is uniform, thereby ensuring that the pattern on the cigarette tipping paper 22 can be displayed in the center during the slitting process.

[0026] In some embodiments, reference Figure 5 As shown, the guide plate 3 is arranged below the winding device 1. Specifically, the winding device 1 winds up the cigarette tipping paper 22 from bottom to top, one end of the guide plate 3 is arranged close to the winding surface of the cigarette tipping paper 22, and the end of the guide plate 3 close to the cigarette tipping paper 22 is tilted upward so that the guide plate 3 can face or align with the winding surface of the cigarette tipping paper 22, thereby ensuring the effect of atomization and humidification, and secondary supplementary humidification is achieved through the guide plate 3, so that the humidification content on the cigarette tipping paper 22 is more uniform.

[0027] In some embodiments, reference Figure 1 and Figure 4 As shown, the humidifying device includes a water tank 19 and a centrifugal atomizer 18 respectively arranged on the first moving platform 7.

The centrifugal atomizer 18 can adopt conventional models and structures on the market. The water tank 19 is connected to an external filtering water supply device, and the water inlet ball valve 8 continuously supplies water to the water tank 19. The filtering water supply device can adopt conventional models and structures on the market, or it can be a conventional water purifier on the market, so as to ensure the quality of the atomized water, prevent damage to the water pump 17 and affect the humidification quality.

[0028] In some embodiments, the output end of the centrifugal atomizer 18 is also connected to a water diversion port, which can be set on the water tank 19 or connected to the water tank 19. The atomized particles generated by the centrifugal atomizer 18 are screened through the water diversion port to ensure that the atomized particles transported to the cigarette wrapping paper 22 and the atomization amount remain consistent, and the screened atomized particles can flow back to the water tank 19 for standby use; in this embodiment, the water diversion port can adopt a conventional structure in the industry.

[0029] In some embodiments, reference Figure 5 As shown, the guide assembly also includes a water receiving trough 5 arranged at the rear end of the guide plate 3, and a reflux hole connected to the water tank 19 is arranged on the water receiving trough 5. Specifically, the guide plate 3 is inclined downward from the winding device 1 to the humidifying device, and the atomized particles of the unhumidified cigarette filling paper 22 can flow back from the guide plate 3 to the water receiving trough 5, and flow back to the water tank 19 through the reflux hole on the water receiving trough 5, so as to prevent the atomized particles from falling onto the equipment.

[0030] In some embodiments, reference Figure 1 and Figure 2 As shown, the humidifying device is also provided with a water mist pressure relief port 20. In this embodiment, the humidifying equipment is used in a constant temperature and humidity workshop, and the excess atomized particles can be sprayed into the production workshop through the water mist pressure relief port 20, which can reduce the load of the workshop's independent humidification mechanism and effectively reduce the equipment operation cost.
