Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of gas path system and ultrasonic welding machine for ultrasonic welding equipment. BACKGROUND

[0002] Ultrasonic welding is to utilize high-frequency vibration wave to be transmitted to the surface of two objects to be welded, under pressure, the surface of two objects is rubbed to form the fusion between molecular layer, ultrasonic welding is converted into 15, 20, 30 or 40KHz current by ultrasonic generator 50 / 60Hz current, the high-frequency electric energy converted is converted into mechanical movement of equal frequency by transducer, then mechanical movement is transmitted to welding head by a set of amplitude changing lever device.

[0003] When ultrasonic wave acts on the contact surface of thermoplastic material, high-frequency vibration of tens of thousands per second is generated, the high-frequency vibration reaching a certain amplitude is transmitted to the welding zone by the upper welding part, because the acoustic resistance is large at the welding zone, i.e. the interface of two welding, local high temperature is generated, and because the material has poor heat conductivity, it cannot be dissipated in time, and is accumulated in the welding zone, so that the contact surface of two materials is rapidly melted, and after a certain pressure, it is fused into one, when the ultrasonic wave stops acting, the pressure is maintained for several seconds, so that it is solidified and formed, thus a solid molecular chain is formed, and the welding purpose is achieved, and the welding strength can approach the strength of the original material.

[0004] In the existing part of ultrasonic welding machine, the power for controlling cylinder is provided by gas path system, the accuracy of gas pressure in gas path system is an important factor to determine the accuracy of power output of control cylinder, at present, the input and output of whole gas path system and control are integrated into an electromagnetic valve seat, which leads to the complexity of internal flow channel of electromagnetic valve seat, and the surface interface of electromagnetic valve seat is numerous, which is easy to cause air leakage phenomenon, and it is not easy to operate to check whether the whole gas path leaks, which leads to that it is very difficult to check some slight air leakage.
