Description

Technical Field

[0001] The utility model relates to the field of diaper processing machinery, and specifically relates to a diaper production line that cuts first and then pastes. Background Art

[0002] A diaper is a disposable sanitary pants, including baby diapers and adult diapers (such as menstrual pants). Existing diapers usually include a diaper body and an absorbent core. During production, the absorbent core (mainly made of non-woven fabric) is usually compounded with the diaper body first, and then O-cut processing is carried out. For example, a disposable underwear production line disclosed in the Chinese utility model patent with the publication number CN220529361U first compounds the inner non-woven fabric, outer non-woven fabric, absorbent body, elastic band and waist elastic band together by gluing through a material compounding unit 5, then sends the compounded material into an O-cut unit through a conveyor belt, and cuts the material through the O-cut unit. Finally, the material continues to move leftward and passes through a product folding and flipping unit, an ultrasonic welding unit, a product cutting unit, a product folding unit and a product small package unit in sequence.

[0003] This processing method has at least the following problems: the two side edges of the absorbent core are flush with the O-cut edges of the diaper body, or the O-cut edges of the diaper body protrude more than the two side edges of the absorbent core. When worn, the O-cut edges of the diaper body come into contact with the human skin, which easily affects comfort. Summary of the Invention

[0004] The purpose of the utility model is to provide a diaper production line that cuts first and then pastes, aiming to overcome the above problems existing in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A diaper production line that cuts first and then pastes includes an O-cut device, a glue spraying device, a second guide roller and a transfer wheel that are sequentially connected in series according to the process for conveying the diaper body; it also includes a variable transverse and variable speed device for conveying the absorbent core, and the variable transverse and variable speed wheel of the variable transverse and variable speed device is in contact with the transfer wheel to form a gluing point for pasting the absorbent core and the diaper body to each other.

[0007] Further, the second guide roller is a negative pressure adsorption roller, and is equipped with a driving motor for rotating the negative pressure adsorption roller.

[0008] Further, it also includes a first guide roller. A first vertical conveying section is formed between the first guide roller and the second guide roller. The glue spraying device is arranged in the first vertical conveying section. A second vertical conveying section is formed between the second guide roller and the gluing point, and the second guide roller is located at the lower position of the first vertical conveying section and the second vertical conveying section.

[0009] Furthermore, the line connecting the centers of the transfer wheel and the variable transverse speed wheel is perpendicular to the second vertical conveying section.

[0010] Furthermore, it further includes a third guide roller. An arc-shaped conveying section is formed between the gluing point and the third guide roller, and the arc-shaped conveying section is closely attached to the transfer wheel.

[0011] Furthermore, the first guide roller and the third guide roller are unpowered guide rollers.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] Firstly, in the present utility model, the O-cut device is first used to perform O-cut on the material of the diaper main body, then glue is applied, and then the transfer wheel and the variable transverse speed wheel of the variable transverse speed device are used in cooperation to paste the absorbent core body and the diaper main body together. It can be seen that the present utility model adopts a processing method of first O-cutting and then gluing, so that the two side edges of the absorbent core body can protrude from the O-cut edge of the diaper main body (usually non-woven fabric), and the more skin-friendly absorbent core body contacts the human skin, avoiding the O-cut edge of the diaper main body from contacting the human skin and improving the comfort of the diaper.

[0014] Secondly, in the present utility model, the second guide roller is a negative pressure adsorption roller and is provided with a driving motor. Using the second guide roller as a power roller provides power for the conveying of the material of the diaper main body. At the same time, its roller surface has adsorption holes for generating negative pressure, and adsorbs the material of the diaper main body during conveying to prevent the material from slipping, improving the accuracy of O-cutting, glue spraying and gluing, and further improving the stability of the production line and the product quality.

[0015] Thirdly, in the present utility model, the second guide roller is located at the lower part of the first vertical conveying section and the second vertical conveying section, so that the material winds around the lower half circle of the second guide roller, and the material is in contact with and negatively pressure adsorbed on the entire lower half circle of the second guide roller, further preventing the material from slipping.

[0016] Fourthly, in the present utility model, the first vertical conveying section is beneficial for glue spraying, and the second vertical conveying section is perpendicular to the center line, so that the material of the diaper main body is between the variable transverse speed wheel and the transfer wheel when entering the gluing point, enabling the absorbent core body and the diaper main body to be glued to each other at the closest possible position, which is beneficial for controlling the close adhesion force during gluing, and avoiding the material of the diaper main body from being too biased towards the variable transverse speed wheel of the material, resulting in the forward movement of the gluing point, or the material of the diaper main body being too biased towards the transfer wheel, resulting in the backward movement of the gluing point.

[0017] Fifthly, in the present utility model, for the third guiding roller, an arc-shaped conveying section is formed between the above-mentioned gluing point and the third guiding roller, and the arc-shaped conveying section is closely attached to the above-mentioned transfer wheel. After gluing, let the material continue to be conveyed along the transfer wheel for a certain distance, which is beneficial to stabilizing the diaper main body and the absorbent core body after gluing.
