Problems solved by technology
At present, baby diapers in the market are all made of elastic waist. On general diaper machines, the narrow elastic waist does not cause much deformation when the product enters the arc cutter. It can be realized by reducing the shape of the arc cutter. , However, if a product with a wide elastic waist is produced, the product will have a large amount of shrinkage deformation due to the wide elastic waist without external force stretching it

The invention discloses a negative-pressure conveyor device with a material stretching function for a production line. The negative-pressure conveyor device comprises a negative-pressure tank assembly, a synchronous belt pulley assembly, a tension pulley assembly and a conveying assembly. The negative-pressure tank assembly is in transmission connection with the synchronous belt pulley assembly by a belt pulley assembly, the tension pulley assembly is in transmission connection with the synchronous belt pulley assembly, and an adjusting device used for adjusting a product pulling angle is arranged between the negative-pressure tank assembly and the synchronous belt pulley assembly and can adjust the deformation of an elastic girdle at a station in the width direction of a product. The negative-pressure conveyor device has the advantages that the center of the product can be adjusted within a certain range by the aid of two lead screws, the required product pulling angle can be adjusted within a certain range by the aid of a rotary screw, and accordingly requirements of all products on current markets can be met.
Description
technical field [0001] The invention relates to the technical field of production line equipment for disposable sanitary products, in particular to a material stretching negative pressure conveying device used on a production line. Background technique [0002] Wide Elastic Waist Stretch Negative Pressure Conveyor is a device on the production line of disposable hygiene products. Its main function is to stretch the product before it enters the arc cutter. At present, baby diapers in the market are all made of elastic waist. On general diaper machines, the narrow elastic waist does not cause much deformation when the product enters the arc cutter. It can be realized by reducing the shape of the arc cutter. However, if a product with a wide elastic waist is produced, the product will have a large amount of shrinkage deformation due to the wide elastic waist without external force stretching it. Contents of the invention [0003] The object of the present invention is to pro...
