Description

Technical Field

[0001] The utility model relates to a die wheel for the production of sanitary products. Background Art

[0002] In the production process of sanitary products, such as the production of sanitary napkins, diapers, disposable diapers, etc., one of the processes is the forming and transfer of the absorbent core. The forming and transfer of the absorbent core usually use a die wheel device to complete the adsorption forming of the core and the transfer after forming.

[0003] Although the existing die wheel device can complete the adsorption forming and transfer of the core during use, it also has certain defects: at present, when users purchase disposable sanitary product machinery and equipment, generally one machine produces several models. In the production equipment of disposable diapers, the adsorption die wheel is mainly used for processing absorbent cores. A number of grooves matching the shape of the absorbent core are formed on the outer circumference of the die wheel body, and the original is adsorbed into the grooves by negative pressure for forming processing. However, the groove size on each current adsorption die wheel is fixed, that is, only absorbent cores of one size can be processed. When absorbent cores of different sizes need to be processed, it is necessary to replace the adsorption die wheels of different models in the equipment. However, the existing die wheels are inconvenient to replace, which requires a large amount of time and labor for maintenance and replacement, greatly reducing the production efficiency and thus affecting the production profit of the enterprise. Therefore, it is necessary to develop a new type of die wheel to solve the problems encountered in the use of existing die wheels. Summary of the Utility Model
