Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 , a packaging device for sanitary napkin production, comprising a packaging machine 1, a conveying device 2 and an adjusting device, wherein the conveying device 2 is installed at one end of the packaging machine 1, and a conveyor belt 3 is installed at the top of the conveying device 2. A fixed frame 4 is arranged directly above the conveying device 2, and three groups of rectangular grooves 5 are opened in the top wall of the fixed frame 4. The adjusting device comprises a bidirectional screw 6, a slider 7, a limit plate 8 and a driving device. The bidirectional screw 6 is rotatably installed in the three groups of rectangular grooves 5, and the slider 7 is threadedly installed at the left and right ends of the bidirectional screw 6. The limit plate 8 is fixedly connected to the bottom wall of the slider 7, and the bottom wall of the limit plate 8 is close to the conveying device 2. The driving device is installed at one end of the three groups of bidirectional screws 6. In this embodiment, when in use, the packaging device packs the sanitary napkins and passes through the conveying device The conveyor belt 3 on the device 2 is transported out. When it is necessary to adjust the width of the sanitary napkins after packaging, the driving device is started. The driving device drives the three groups of bidirectional screws 6 to rotate simultaneously. During the rotation, the three groups of bidirectional screws 6 drive the sliders 7 at both ends to move linearly in the rectangular groove 5. The sliders 7 drive the limit plates 8 connected to the bottom ends to move from the two ends to the middle until the two groups of limit plates 8 are adjusted to the required width, and the operation of the driving device is stopped. When it is necessary to increase the spacing between the two groups of limit plates 8, the driving device drives the three groups of bidirectional screws 6 to reverse, and the three groups of bidirectional screws 6 drive the two groups of sliders 7 to drive the limit plates 8 to move toward the two ends. The spacing between the two groups of limit plates 8 can be adjusted according to needs, and can be accurately adjusted according to the actual product size, thereby reducing unnecessary waste and adapting to the switching of different products on the production line.

[0025] In actual use, it is further convenient to make the driving device drive the three groups of bidirectional screws 6 to rotate simultaneously. The utility model is improved in that the driving device includes gears 9, a rotating shaft 10 and a driving motor 11. One end of the three groups of bidirectional screws 6 passes through the side wall of one side of the fixed frame 4 and is installed with the rotating shaft 10. The outer wall of the rotating shaft 10 is installed with the gear 9. The three groups of gears 9 are meshed and connected by a toothed belt 12. The end of the rotating shaft 10 located at the center of the fixed frame 4 is sleeved with the driving motor 11. Start the driving motor 11, and the output end of the driving motor 11 drives the rotating shaft 10 at the center of the fixed frame 4 to rotate, and the rotating shaft 10 drives the corresponding gear 9 to rotate. The gear 9 drives the three groups of gears 9 to rotate simultaneously through the toothed belt 12, and the three groups of gears 9 drive the three groups of rotating shafts 10 to rotate. The three groups of rotating shafts 10 drive the three groups of bidirectional screws 6 to rotate simultaneously. The forward and reverse rotation of the driving motor 11 can realize the simultaneous forward and reverse rotation of the three groups of bidirectional screws 6.

The limiting plates 8 with rounded corners 14 are mainly used to prevent the sanitary napkins from being damaged due to impact during transportation, while ensuring that the sanitary napkins can be transported along a predetermined path. The design feature of this limiting plate 8 is that its edge presents a smooth curve instead of a sharp right angle, which can reduce the friction and impact between the sanitary napkin and the limiting plate 8, thereby protecting the surface of the sanitary napkin from damage.

[0029] Preferably, in this embodiment, the fixing frame 4 is of an inverted U-shape design.

[0030] In actual use, the stability and accuracy of the operation of the drive motor 11 are further guaranteed. In this embodiment, the drive motor 11 is a servo motor. The servo motor can control the position, speed and torque with high precision. The servo motor adopts closed-loop control and has good stability. It can avoid stalling, vibration and other problems, thereby ensuring the stability and accuracy of the operation of the drive motor 11.
