Description

Technical Field

[0001] The utility model relates to the technical field of nursing pad production, in particular to a folding device for nursing pad production. Background Art

[0002] Nursing pads are a kind of disposable sanitary products, mainly used in hospital surgery, gynecological examination, maternal care, child care, incontinence of paralyzed patients, etc. Nursing pads are produced continuously and finally folded, cut and folded horizontally on the production line to form the desired shape.

[0003] For example, a Chinese patent (publication number: CN215625790U) discloses a nursing pad folding device, which relates to the field of nursing pad production equipment, including a folding platform and a cutting mechanism. The folding platform includes a first folding platform and a second folding platform. The first folding platform includes a first cylinder and a first folding plate. The output end of the first cylinder is connected to the first folding plate. The first folding plate includes a bending portion and a folding portion. The second folding platform includes an upper folding table, a lower folding table and a second folding plate. The lower folding table is connected to the end of the first folding platform through a feeding plate. The cutting mechanism is located next to the lower folding table. The width between the two first folding plates is controlled by the cylinder, so that the first folding plate can perform preliminary folding on the nursing pads of different models transmitted, and then the second folding plate performs a secondary folding process on the nursing pads. It is simple and convenient, so that it can perform folding operations on nursing pads of different models without complicated debugging and equipment replacement.

[0004] The above-mentioned nursing pad folding device still has certain shortcomings. The width between the two first folding plates is controlled by a cylinder, so that the first folding plate can perform preliminary folding on the nursing pads of different types transmitted, and then the second folding plate performs a second folding process on the nursing pad. However, when the nursing pad is folded by the first folding plate on the first folding platform, the nursing pad will be pushed to the other side, which may easily lead to insufficient folding of the nursing pad. Therefore, a folding device for nursing pad production is proposed to solve the above-mentioned problem. Utility Model Content
