Abstract

The present invention relates to the field of production of disposable hygiene products, in particular to an ultrasonic double-head sealing device, which includes a first mounting plate arranged on the assembly line, a first welding mechanism arranged at the front end of the first mounting plate, a second mounting plate, a device The second welding mechanism at the front end of the second mounting plate, the first mounting plate and the second mounting plate are tightly connected through the lower connecting plate and the upper connecting plate, the first welding mechanism includes a first ultrasonic welding head, The first rotating bottom roller below the first ultrasonic welding head, the second welding mechanism includes a second ultrasonic welding head, a second rotating bottom roller located below the second ultrasonic welding head, the first rotating bottom roller, the first rotating bottom roller The two rotating bottom rollers are heating rollers. It solves the technical problems of poor sealing effect and small sealing pulling force in the existing ultrasonic double-head sealing device during high-speed production, and accordingly proposes an ultrasonic double-head sealing process.

Description

technical field [0001] The invention relates to the production field of disposable sanitary products, in particular to an ultrasonic double-head sealing device and a sealing process thereof. Background technique [0002] At present, in the field of disposable sanitary products, many parts are bonded and fixed by ultrasonic welding mechanism, especially the waist welding of pull-up pants is often carried out by ultrasonic welding mechanism. In the existing pull-up pants, its product structure can refer to a kind of pull-up pants disclosed in the Chinese patent application number: CN202010022624.9. In order to improve the wearing comfort of the baby, the length of the waist circumference is often increased. This makes ultrasonic welding more difficult, that is to say, it is often difficult to use one ultrasonic welding head to form a result with good sealing effect and qualified sealing tension. Therefore, two ultrasonic welding heads are often used to pull pants. Welding of ...
