Gas supply system and gas supply method

Abstract

The invention discloses a gas supply system and a gas supply method. The gas supply system comprises a gas supply device and a buffer tank. The gas supply device communicates with an inlet of the buffer tank through a pipe E. A pipe F is connected with an outlet of the buffer tank. A pressure control valve is arranged on the pipe E. A digital display pressure gauge and a buffer gas outlet valve are installed on the pipe F on the outlet of the buffer tank respectively. The pipe F is provided with a gas filter and a gas quality and flow controller in sequence. When the gas supply system is usedfor supplying gas to a plasma surface treatment shoe machine, the gas in the gas supply device firstly flows into the buffer tank, so that the pressure of the buffer tank is kept at a stable and low value all the time, it is avoided that gas inlet stability is influenced by gas liquefaction, solid impurities are filtered out by the gas filter, flow of the gas is accurately controlled automaticallyby the gas quality and flow controller, the gas flows into a vacuum chamber of the shoe machine finally, and the whole gas supply system is easy to operate and convenient to install.

Description

technical field [0001] The invention relates to an air supply system and an air supply method thereof. Background technique [0002] In the process of shoe material processing, plasma shoe material surface treatment machine (hereinafter referred to as shoe machine) is needed. The shoe machine uses low-temperature plasma technology to put the shoe material to be processed into the cavity of the shoe machine and pump it to a high vacuum state to form a vacuum chamber. Then the gas catalyst is fed through the gas supply system, and finally the medium-frequency alternating current is applied to ionize the gas in the cavity to form plasma, which bombards the surface of the shoe material and increases the groups on the surface of the shoe material, thereby increasing the adhesion of the glue to the shoe material. [0003] The traditional glass rotameter is used to measure the gas flow in the commonly used gas supply system. The traditional glass rotameter can only set a fixed para...

Problems solved by technology

[0003] The traditional glass rotameter is used to measure the gas flow in the commonly used gas supply system. The traditional glass rotameter can only set a fixed parameter at a time. Insufficient flow rate will affect the treatment effect; the traditional glass rotameter needs to be frequently adjusted every time the model is changed and the parameter test is adjusted; the traditional glass rotameter cannot be quantified when adjusting, and each adjustment requires two people , one person adjusts the flowmeter, and the other person checks the control panel parameters to prevent excessive adjustment or insufficient adjustment, which is very inconvenient to adjust

[0004] In the process of shoe material processing, the commonly used gas supply system is direct gas supply from the catalyst gas storage cylinder, which not only makes it difficult to control the output of gas, but also affects the stability of the shoe machine cavity intake, and the gas will also appear during the transportation process. The situation of liquefaction will further affect the stability of intake air
