Ultrasonic sealing and pressing equipment and process

Abstract

The invention relates to the technical field of mechanical sealing and pressing, and discloses ultrasonic sealing and pressing equipment and process. The ultrasonic sealing and pressing equipment comprises a rotating roll, fixing assembly, a clamping mechanism, an ultrasonic sealing and pressing assembly and a cutter assembly, wherein the fixing assembly is used for fixing a product to be sealed and pressed on the surface of the rotating roll; the clamping mechanism is used for clamping the waistline of the product to be sealed and pressed; the ultrasonic sealing and pressing assembly is fixedly mounted on the outer side of the rotating roll in a radial direction; the fixing assembly and the clamping mechanism are connected to the rotating roll, and are arranged along the peripheral direction of the rotating roll at intervals; a feeding opening is formed in front of the ultrasonic sealing and pressing assembly; and a discharging opening is formed in the rear of the cutter assembly. Inthe sealing and pressing process of the ultrasonic sealing and pressing equipment, the product to be sealed and pressed can be clamped, a sealing and pressing position and the position of a cutter arecontrolled accurately, and the flexibility of the sealing and pressing opening is good.

Description

technical field [0001] The invention relates to the technical field of mechanical sealing and pressure, in particular to an ultrasonic sealing and pressure equipment and process. Background technique [0002] Baby training pants make babies feel wet when they urinate, so they can train babies to get out of diapers slowly. Now more and more mothers choose to use baby training pants. [0003] In the production process of baby training pants, a key step is to seal and press the waistband of the training pants. In the existing baby training pants production line, the sealing and pressing equipment uses one or more high-temperature heating rollers to act on an anvil heated at the same high temperature. Pressed products on rolls, known as heat-sealed forms. Since the single-roller heat-press sealing form only seals and presses the product once, the sealing strength of the product cannot meet the customer's requirements when the production line runs at high speed, and the single-r...

AI Technical Summary

Problems solved by technology

Since the single-roller heat-press sealing form only seals and presses the product once, the sealing strength of the product cannot meet the customer's requirements when the production line runs at high speed, and the single-roller heat-press sealing structure is designed in a split form. The separate process design of the closing mechanism and the product cutting mechanism, due to the strong elasticity of ...
