Embodiment Construction

[0013] Refer to attached picture. The present invention comprises a cyclically rotating annular air chamber 1 connected with an air intake pipe 2 , and several rotating air supply mechanisms provided with air supply pipes 3 which move synchronously with the air chamber at intervals.

[0014] The rotary air supply mechanism includes an air supply valve 4 and a rotary air supply joint 5 connected to the air supply valve, and the rotary air supply joint is connected to an air supply pipe.

[0015] An opening mechanism and a closing mechanism of the gas supply valve are respectively provided at the two ends of the operating line.

[0016] The switch 41 of the gas supply valve is provided with an inclined surface 42, and the opening mechanism is an inclined roller 43 matched with the inclined surface. When the inclined surface 41 contacts the roller 42, the switch is gradually lifted to open the air supply valve. The closing mechanism is a bumper with an inclined surface. The ref...

Abstract

An automatically cyclic gas supply apparatus for the production line has a cyclically rotating annular gas chamber with several rotating gas supplying mechanisms with gas supply tube, which are moving synchronously with said gas chamber. Said rotating gas supplying mechanism can synchronously follow a workpiece on production line for supplying gas to it.

Description

technical field [0001] The invention relates to an automatic circulation air supply device used in a production line to supply air to moving objects. Background technique [0002] At present, gas is supplied to moving objects on the production line that requires gas supply, such as providing nitrogen protection when welding copper pipes on the evaporator and condenser welding production line of air conditioners. Since the workpiece is in motion, the operator must drag the gas supply pipe Marching operation is labor-intensive and easily affects the quality of work. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic circulation air supply device that overcomes the above-mentioned defects. For this reason, the present invention adopts the following technical solutions: it includes a cyclically rotating annular air chamber, the annular air chamber is conn...
