Description

Technical Field

[0001] The utility model relates to the field of anti-wrinkle equipment, in particular to an anti-wrinkle processing device for sanitary napkin wings. Background Art

[0002] The sanitary napkin wing anti-wrinkle device of the sanitary napkin processing equipment is used to flatten and anti-wrinkle the sanitary napkin wings. The wings are located on the side of the sanitary napkin body. During production, the sanitary napkin body and wings are first produced separately, and then the two are combined at the connection point, and finally cut by a forming knife. The sanitary napkin body and wings are split structures with reasonable structure, so that the sanitary napkin body and wings can be produced separately. However, after completing the napkin body cutting process, the wings are easily wrinkled because the speed of transmission on the conveyor belt is too fast when they are folded inward, which affects the completion quality of the next process, that is, pasting the wing release paper, and thus seriously affects the product quality and image.

[0003] To solve this problem, the application number CN202121441418.8 proposes a sanitary napkin wing anti-wrinkle device for sanitary napkin processing equipment, wherein the device comprises a frame, a motor, an electric cylinder and a press frame. Bearing seats are provided on both sides of the two ends of the frame, a transmission shaft is provided between the opposite bearing seats, the motor is fixed at the position corresponding to the transmission shaft on the frame, the output end of the motor is connected to the transmission shaft, a conveyor belt is provided on the transmission shaft at both ends of the frame, a door frame-shaped press frame is provided in the middle of the frame to cross the conveyor belt, and a pressure frame is provided in the middle of the top of the press frame. An electric cylinder is installed, and passage holes are opened at both ends of the pressing frame. A guide sleeve is slidably inserted into the passage hole. The top of the guide sleeve is connected to a bridge parallel to the pressing frame, and the other end of the bridge is connected to the telescopic end of the electric cylinder. The bottom end of the guide sleeve is sleeved with a guide column. A pad is arranged between the pressing plate and the guide column of the utility model. The pad is elastically connected to the pressing plate, which can make the pressing plate swing with the movement of the conveyor belt when it contacts the sanitary napkin wings, thereby realizing the flattening and wrinkle-proofing of the wings while the conveyor belt is driven, making the product more beautiful.

[0004] In the existing patent, a pressing plate is used to flatten and remove wrinkles on the sanitary napkin wings. When the pressing plate is used to apply a flattening force to the sanitary napkin wings, since the pressing plate only flattens in one direction and the direction is relatively single, the side wings may fold in the same direction as the flattening direction, causing the wrinkles on the side wings to deepen further during the pushing process, causing the sanitary napkin wings to wrinkle again.
