Ultrasonic sealing-pressing device and method

Abstract

The invention discloses an ultrasonic sealing-pressing device and an ultrasonic sealing-pressing method. The ultrasonic sealing-pressing device comprises a support frame, an anvil roller, two groups of ultrasonic devices and one group of material conveying device, wherein the anvil roller, the ultrasonic devices and the material conveying device are respectively arranged on the support frame, the two groups of ultrasonic devices are symmetrically arranged on the two sides of the anvil roller, and a strip material product is placed on the material conveying device. The ultrasonic sealing-pressing method comprises the steps that the material conveying device continuously conveys the strip material product, when the sealing-pressing position of the strip material product reaches the anvil roller, a first floating roller and a second floating roller carry out vertical movement in contrary directions, so that the strip material product positioned above the first floating roller and the second floating roller is in a relatively static state, and the anvil roller and the ultrasonic devices on the two sides of the anvil roller carry out sealing-pressing on the strip material product. The ultrasonic sealing-pressing device is simple in structure, the processing precision for the strip material product can be easily guaranteed, the structure of the device is simplified, and meanwhile, the production and manufacturing costs are effectively reduced.

Description

technical field [0001] The invention relates to the field of hygienic product manufacturing equipment, in particular to an ultrasonic sealing pressure equipment and method. Background technique [0002] The traditional baby training pants production line is mainly designed with mechanical structure. Since the continuous strip product runs at high speed, the online sealing time is short. Therefore, the same waist seal must be sealed three times to meet the sealing quality requirements. Since the same anvil needs to be pressed three times by sealing and pressing devices, according to the needs of the space structure, at least four or more anvils need to be connected with three sets of sealing and pressing devices in a circle to meet the structural design requirements and form a complete set. Sealing assembly. Therefore, the structure of the existing sealing pressure equipment is complicated, it is difficult to guarantee the processing accuracy of the strip product, the phenom...
