Description

TECHNICAL FIELD

[0001] The utility model relates to the field of packing machinery, concretely relates to ultrasonic sealing machine. BACKGROUND

[0002] The ultrasonic sealing machine is one kind of ultrasonic plastic welding machine, which uses ultrasonic energy concentrator to act on the sealing part of the packaging container, so as to close the packaging container. The ultrasonic energy is transmitted to the welding area through the upper welding part, and local high temperature is generated due to the large acoustic resistance at the welding area, i.e. the interface of the two welding parts. Since the plastic has poor thermal conductivity, it cannot be dissipated in time and is accumulated in the welding area, causing the contact surface of the two plastics to melt rapidly, and after a certain pressure is applied, the two plastics are fused into one. After the ultrasonic wave stops acting, the pressure is maintained for a few seconds to make the plastic solidify and form a solid molecular chain, achieving the purpose of welding. The welding strength can be close to the strength of the raw material, and it is suitable for packaging of plastic containers.

[0003] As shown in the Chinese patent with publication number CN101607440A, the distance between the upper and lower working heads of the conventional ultrasonic sealing machine cannot be adjusted, and it cannot be well adapted to workpieces of different thicknesses. CONTENT OF THE UTILITY MODEL
