Abstract

The invention relates to the field of disposable hygienic product production, in particular to an ultrasonic double-end sealing device. The ultrasonic double-end sealing device comprises a first mounting plate, a first welding mechanism arranged at the front end of the first mounting plate, a second mounting plate and a second welding mechanism arranged at the front end of the second mounting plate, wherein the first mounting plate, the first welding mechanism, the second mounting plate and the second welding mechanism are arranged along an assembly line. The first mounting plate and the second mounting plate are firmly connected through a lower connecting plate and an upper connecting plate. The first welding mechanism comprises a first ultrasonic welding head and a first rotating bottom roller arranged below the first ultrasonic welding head, and the second welding mechanism comprises a second ultrasonic welding head and a second rotating bottom roller arranged below the second ultrasonic welding head. And the first rotating bottom roller and the second rotating bottom roller are both heating rollers. The technical problems that an existing ultrasonic double-end sealing device is poor in sealing effect and small in sealing tension during high-speed production are solved, and an ultrasonic double-end sealing process is correspondingly provided.

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 ...
