Description

Technical Field

[0001] This utility model relates to the field of air pressure controller technology, specifically a high-precision digital pulse multi-channel air pressure controller. Background Technology

[0002] Pneumatic controllers are widely used devices in industry. They are essential for modern industries that require significant efficiency improvements, and are widely applied in areas such as multi-channel dispensing controllers.

[0003] In order to save costs, existing multi-channel dispensing controllers do not have air tanks for each output air pressure. This results in unstable air pressure when each air pressure is precisely adjusted, which affects the output of glue or other liquids and affects product quality. Secondly, since the viscosity of liquids is greatly affected by temperature, current multi-channel dispensing controllers do not have temperature monitoring. As a result, the control parameters set for each output cannot be recorded, and the data lacks reference value when analyzing it later.

[0004] Therefore, we propose a high-precision digital pulse multi-channel pneumatic controller to solve the problems mentioned above. Utility Model Content

[0017] The air inlet 121 is used for gas output, connecting clean external gas to the dispensing controller. The air inlet 121 is connected to the air tank 5 and the negative pressure regulating valve 101.

[0018] Vent 122 is used to reduce the noise of exhaust when there is a vacuum leak.

[0019] The gas storage tank 5 is used to store gas. The gas storage tank 5 is connected to the positive pressure regulating valve 102 to provide a stable gas pressure for the glue supply equipment. There are eight gas storage tanks 5. Each gas storage tank 5 is injected with air from the air inlet 121 and then output to the positive pressure regulating valve 102.

[0020] The positive pressure regulating valve 102 is connected to the gas storage tank 5 and the solenoid valve 6. The positive pressure regulating valve 102 is equipped with a knob. There are several positive pressure regulating valves 102. Each positive pressure regulating valve 102 is independently connected to a gas pressure output port 104. The positive pressure of the gas pressure output port 104 is adjusted by the knob, and the value is displayed on the touch screen 103.

[0021] The negative pressure regulating valve 101 provides back suction pressure, and the value is displayed on the touch screen 103.

[0022] The pressure sensing board 3 is connected to a pressure sensor, which is installed on the pipelines of each negative pressure regulating valve 101 and positive pressure regulating valve 102. The pressure sensor detects the pressure value in the pipelines of the negative pressure regulating valve 101 and positive pressure regulating valve 102 and displays it on the touch screen 103.

[0023] Solenoid valve 6 controls the connection and disconnection of each air passage.

[0024] The air pressure output port 104 is connected to the hose through a pipeline to provide air pressure to the hose.

[0025] The negative pressure leakage component 2 generates vacuum pressure by venting.

[0026] Data board 4 collects various data and is connected to touch screen 103 to provide various display data to touch screen 103.

[0031] Working principle: In glue supply mode, after setting parameters through the touch screen 103, the controller is started. The solenoid valve 6 connects the positive pressure regulating valve 102 and the air passage of the glue supply port. Gas enters the eight air tanks 5 from the air inlet 121. The air tanks 5 adjust the air pressure of the air passages individually through several positive pressure regulating valves 102. The positive pressure sensor transmits the pressure values ​​of the several positive pressure regulating valves 102 back to the data board 4. The data board 4 analyzes the data and displays it on the touch screen 103. The adjusted gas is then supplied to several glue supply devices through several solenoid valves 6 to perform glue supply operations until the glue supply is completed. In the glue return mode, after setting parameters via the touch screen 103, when the glue supply operation is completed, the positive pressure regulating valve 102 closes and the negative pressure regulating valve 101 opens. The solenoid valve 6 connects the negative pressure leakage component 2 and the air passage of the glue supply port separately. The gas flows from the air inlet 121 through several negative pressure regulating valves 101, which individually regulate the air pressure of several air passages. The negative pressure sensor transmits the pressure values ​​of several negative pressure regulating valves 101 back to the data board 4, which is then analyzed by the data board 4 and displayed on the touch screen 103. After the several gas passages are regulated, they generate negative pressure after passing through the negative pressure leakage component 2, which creates a back suction effect on the glue supply equipment to prevent glue leakage.
