Ultrasonic sealing machine capable of sealing bags stably and firmly

Abstract

The invention relates to an ultrasonic sealing machine capable of sealing bags stably and firmly. The ultrasonic sealing machine comprises a support vertically extending and a machine head arranged on the support. The machine head comprises a welding head extending in the vertical direction, an ultrasonic transducer connected with the welding head and a drive device for driving the welding head to move in the vertical direction. The ultrasonic sealing machine is characterized by further comprising a work table arranged on the support, the work table is arranged below the welding head and extends transversely, and the work table is provided with a groove corresponding to the welding head in position. According to the ultrasonic sealing machine, the work table is available and enables an opening of a packing bag to be conveniently folded and to be vertically welded, due to arrangement of the groove, the position of the opening of the packing bag can be limited, and stability and firmness are improved when the opening is sealed. In particular, when the groove is designed to be L-typed, the opening of the packing bag can be naturally stacked in the groove, and sealing quality is further improved.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a sealing machine for packaging bags. Background technique [0002] Packaging machinery refers to machinery that can complete all or part of the product and commodity packaging process, and is widely used in food, medicine, daily chemical hardware and other industries. The packaging process includes main processes such as filling, wrapping, and sealing, as well as related pre- and post-processes, such as cleaning, stacking, and disassembly. The sealing machine is mainly responsible for the sealing process of packaging containers. Products filled into packaging bags are usually sealed by seams, heat sealing, ultrasonic waves, etc. Ultrasonic sealing does not require adhesives and is fast and reliable. At present, the packaging bag filled with the product is usually placed upright, and the opening end is also in an upright state for sealing. Since the two layers of materials at the openi...

AI Technical Summary

Problems solved by technology

At present, the packaging bag filled with the product is usually placed upright, and the opening end is also in an upright state for sealing. Since the two layers of materials at the opening end of the packaging bag are not easy to knead to the state of being close to each other, it not only brings inconvenience to the sealing, but also affects Sealing quality, resulting in defects such as poor sealing, wrinkled packaging bags, etc.
