Problems solved by technology

However, some defects were exposed in the actual production process. The two sets of rubber band arrangement devices are respectively installed on both sides of a belt, and are driven by a set of motor components.
When working, the two sets of rubber band arrangement devices can only do symmetrical reciprocating movements, so the arc-shaped elastic bands arranged on the legs can only appear in a symmetrical structure on the product. The product structure is single and the flexibility is poor.
Moreover, the device only solves the problem of elastic arc forming; the product is a semi-finished product and requires follow-up production, which virtually increases production costs and reduces production efficiency

Abstract

The invention discloses a combination mechanism for an arc-shaped leg rubber band. The combination mechanism comprises a rack and further comprises an arc-shaped rubber band forming device and an rubber band combination and traction device which are respectively fixed on the rack, the rubber band combination and traction device is used for continuously performing combination and traction on materials and consists of two groups of parallelly-placed rubber-forming components in opposite direction, each rubber-forming component is provided with a servo motor in a matching way, and the servo motors drive the respective rubber-forming components to move forwardly and reversely, the rubber band combination and traction device consists of a traction wheel component and an air cylinder pressing wheel component for squeezing the traction wheel component. By controlling in a mutually independent way, the accurate and flexible adding of the arc-shaped leg rubber band is facilitated, the more accurate and evener distribution of the arc-shaped leg rubber band on a product is also facilitated.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to an arc-shaped leg elastic composite mechanism. Background technique [0002] With the rapid development of the disposable sanitary products industry, people have higher and higher requirements for disposable sanitary products, that is, the products are required to look beautiful, and more importantly, they are required to be comfortable to wear. For this reason, applying curved leg elastics to the product not only meets people's aesthetic requirements, but also combines the structural principles of the human body to improve the wearing comfort of the product. However, as more and more requirements are put forward, the existing leg elastic arc application mechanism can no longer meet the ever-changing needs of consumers for sanitary products due to its limitations. [0003] Chinese patent CN201855354U "Apparatus for S Elastic Bands on Legs of Adult Paper Diapers" discl...
