The invention relates to the technical field of interphones as digital products, and discloses wet
etching equipment of an antenna
baseband for an interphone. The wet
etching equipment comprises a shell, wherein a rotating shaft is movably connected to the interior of the shell, a movable plate is movably connected to the surface of the rotating shaft, a sliding rail is formed in the movable plate, a compression spring is connected to the surface of the sliding rail in a sliding mode, a hollow rod is movably connected to the lower end of the compression spring, a feed
pipe is movably connectedto the right end of the hollow rod, a
spoiler is movably connected to one end, which is far from the hollow rod, of the feed
pipe, an adjusting tank is movably connected to one end, which is far fromthe feed
pipe, of the hollow rod, spring rods are movably connected to the interior of the adjusting tank and are located on both sides of a guide rod respectively, and a clamping plate is movably connected to one end, which is far from the guide rod, of an
airflow pipe. An internal flowing space is narrowed, and therefore,
chemical agents in a
liquid storage bag can stop flowing out by utilizingsuction
airflow when the flow direction of the
chemical agents on the surface of a paster is changed, so that the effect of controlling the flow direction of corrosive liquid is achieved.
