The principle of ultrasonic sealing machine
Ultrasonic sealing machine is a kind of ultrasonic plastic welding machine. It uses ultrasonic concentrator to act on the sealing part of packaging container to seal the packaging container. Ultrasonic energy is transmitted to the welding area through the upper weldment. Since the acoustic resistance of the welding area, i.e. the interface between the two welds, is large, local high temperature will be generated. Due to the poor thermal conductivity of plastic, it cannot be dissipated in time and gathers in the welding area, causing the contact surface of the two plastics to melt rapidly. After a certain pressure is applied, it is fused into one. When the ultrasonic wave stops working, the pressure is allowed to continue for a few seconds to solidify and form, thus forming a strong molecular chain to achieve the purpose of welding. The welding strength can be close to the strength of the raw materials, which is suitable for the packaging of plastic containers.
Utien Pack's sealer's advantages
Established in 1994 in Hangzhou, China, Utien Pack, is a technical enterprise dedicated to manufacturing and developing automated packaging machinery. We focus on self-developing packaging solution and technology innovation.Our ultrasonic sealers are of outstanding quality and reliability.
1.Auto tube loading
The plastic tube is placed in the collecting tank with the opening outward. The swing mechanism controls the tube to enter the tube drop channel one by one, and the tube dropping mechanism swings back and forth 90° to place the tube into the lower tube base to complete the tube loading.
2.Auto orientation
After the tube is loaded, the rotary table to drive the tube to the marking station. The position of the tube is adjusted by identifying the positioning mark on the tube through the photoelectric switch. Keep all tubes facing in the same direction.
3.Auto filling
The filling part is composed of filling head, material tank, etc. The piston is driven to move by the pneumatic parts to extrude the material and pour it into the lower tube from the material tank. It can accurately controlled by controlling the extrusion time, and automatic filling can be realized from 20g to 250g.
4.Ultrasonic sealing
Plastic molecules are vibrated and strongly jointed together with ultrasonic power to achieve the purpose of sealing, it can be sealed under different conditions. It can be firm and nice welding regardless of the material remaining on inner wall of the tubes or there is water at the sealing place, and it is not easy to produce false seal.
5.Cutting surplus edge
Automatic edge cutting, cutting off the surplus edge at the end of the tube after sealing, making the end more smooth, can be cut out a variety of different shapes or lines of the tail to meet the design requirements.
