Three-folding device for sanitary napkins

Abstract

The invention discloses a sanitary towel three-folding device which comprises a rack, a base, a conveying belt mechanism, a first conveying belt mechanism, a second conveying belt mechanism, two guide plates and two pressing wheel parts. The conveying belt mechanism comprises a folding part, a first driving wheel, a first tensioning wheel part and a conveying belt; the conveying belt is arranged on the first driving wheel, two transmission belt wheels of the folding part and a tensioning wheel of the first tensioning wheel part in a sleeving manner; the first conveying belt mechanism comprises a first conveying belt and a second conveying belt which are sequentially arranged in the axial direction of the second driving wheel, and conveying channels are formed between the second conveying belt and the conveying belt and between the first conveying belt and the conveying belt. The second conveying belt mechanism comprises a third conveying belt, and a conveying channel is formed between the third conveying belt and the conveying belt. The two guide plates are vertically arranged on the two sides of the conveying belt correspondingly and are arranged in a staggered mode. The pressing wheel parts are located behind the corresponding guide plates. The sanitary towel folding device enables sanitary towel conveying to be reliable and high in precision and enables the folding effect to be good.

Description

technical field [0001] The invention relates to the technical field of sanitary napkin production equipment, in particular to a three-fold device for sanitary napkins. Background technique [0002] Disposable sanitary napkin products generally have wing structures on both sides of the main body of the product. When the sanitary napkin product is cut by a shape cutter to obtain individual products, a three-fold device is usually used to protect the protective wings on both sides of the main body of the product. The wings are folded from both sides to the main body. With the rapid development of sanitary napkin machines, people have higher and higher requirements for disposable sanitary napkins, and correspondingly higher and higher requirements for material transportation. Therefore, the existing Due to the low conveying accuracy, defects such as tearing of the wings and irregular folding will occur during the folding process, which will affect the product quality, especially...

[0002] Disposable sanitary napkin products generally have wing structures on both sides of the main body of the product. When the sanitary napkin product is cut by a shape cutter to obtain individual products, a three-fold device is usually used to protect the protective wings on both sides of the main body of the product. The wings are folded from both sides to the main body. With the rapid development of sanitary napkin machines, people have higher and higher requirements for disposable sanitary napkins, and correspondingly higher and higher requirements for material transportation. Therefore, the existing The device will cause defects such as tearing of the flaps and irregular folding during the folding process due to low conveying accuracy, which will affect product quality, especially at high speeds, which will cause a lot of waste of resources
