[0055] The lifting end of the lifting assembly is connected to the negative pressure air pipe 31;

[0056] In use, the lifting component drives the negative pressure air pipe 31 to move upward, which can open the bag opening. Then, the pushing mechanism 5 moves the feeding channel 2 forward, so that the opening mechanism 4 at the front of the feeding channel 2 enters the bag opening. The opening mechanism 4 opens the bag opening, allowing disposable hygiene products to pass through the feeding channel 2 into the packaging belt, which greatly improves the automation efficiency of disposable hygiene products packaging and is suitable for large-scale promotion and use.

[0057] In this embodiment, the lifting assembly includes a bearing seat 34, a drive shaft 35, a drive wheel 33, and a rack 32;

[0058] The bearing housing 34 is fixedly installed on the workbench 1;

[0059] The drive shaft 35 is mounted in the bearing housing 34 and is connected to the motor.

[0060] Two sets of drive wheels 33 are provided, which are symmetrically arranged on the drive shaft 35;

[0061] Two sets of racks 32 are provided, corresponding to and meshing with the corresponding drive wheels 33. The top of the rack 32 is connected to the corresponding negative pressure air pipe 31 through a fastener. The worktable 1 is provided with a sliding groove for the rack 32 to slide up and down.

[0062] In use, the motor drives the drive shaft 35 to rotate, and the drive shaft 35 causes the rack 32 to move up and down through the drive wheel 33.

[0063] In this embodiment, two sets of the opening mechanism 4 are provided. The two sets of opening mechanisms 4 are arranged opposite to each other at the front opening of the feeding channel 2. The opening mechanism 4 includes an upper opening plate 48, a lower opening plate 47, a control shaft 410, a C-shaped frame 41, a control cylinder 44, a slider 42, a first connecting rod 46, a second connecting rod 43, a rotating plate 45, a fixed plate 49, and a rotating shaft 411.

[0064] The U-shaped frame 41 is installed on one side of the outer wall of the feeding channel 2;

[0065] The control shaft 410 is vertically arranged, and both ends of the control shaft 410 are mounted in the bracket 41 via bearings;

[0066] The rotating plate 45 is fixedly installed on the control shaft 410, and one end of the rotating plate 45 is connected to the lower support plate 47, while the other end of the rotating plate 45 is rotatably connected to the piston rod of the control cylinder 44.

[0070] The surface of the U-shaped frame 41 is provided with a vertically arranged sliding groove, and the slider 42 is slidably installed in the sliding groove;

[0071] In use, the extension and retraction of the control cylinder 44 controls the rotation of the rotating plate 45 around the control shaft 410, thereby controlling the opening and closing of the lower support plate 47. When the two lower support plates 47 are closed and have sharp angles, it is easy for them to enter the packaging bag. After the two lower support plates 47 enter the packaging bag, under the control of the control cylinder 44, the two lower support plates 47 open, which can open the bag opening to the maximum state. While the rotating plate 45 rotates outward around the control shaft 410, the fixed plate 49 also rotates outward around the control shaft 410. With the cooperation of the slider 42, the first connecting rod 46, and the second connecting rod 43, the rotating shaft 411 rotates upward, and the upper support plate 48 opens the packaging bag upward, realizing the dead corner positioning of the packaging bag, which is conducive to the smooth entry of materials into the packaging bag.

The end of the control rod 53 away from the swing arm 52 is rotatably connected to the drive rod 54, and the end of the drive rod 54 away from the control rod is rotatably connected to the bottom of the feeding channel 2.

[0076] In use, when the drive motor 51 causes the swing arm 52 to rotate, the feeding channel 2 can move within the guide rail with the cooperation of the control rod 53 and the drive rod 54.

[0077] In this embodiment, the feeding channel 2 consists of feeding plates arranged symmetrically on the left and right sides. The gap between the two sets of feeding plates is the feeding gap, and the size of the gap between the two sets of feeding plates is adjustable.

[0078] The working principle of this utility model is as follows:

[0079] The lifting component drives the negative pressure air pipe 31 to move upward, which can open the bag opening. Then, the pushing mechanism 5 moves the feeding channel 2 forward, so that the opening mechanism 4 at the front of the feeding channel 2 enters the bag opening. The opening mechanism 4 opens the bag opening, allowing disposable hygiene products to pass through the feeding channel 2 into the packaging belt, which greatly improves the automation efficiency of disposable hygiene products packaging and is suitable for large-scale promotion and use.
