The utility model relates to the technical field of
sponge ear cap production, in particular to a
sponge ear cap
pigment adding device. The
sponge ear cap
pigment adding device comprises an isolation frame, a conveying
assembly, storage barrels, a feeding
pipe, a dustproof cover, a water pump, a connecting
pipe, a spraying
pipe and a guide plate, the isolation frame is obliquely designed, the conveying
assembly is arranged in the isolation frame, the storage barrels are arranged on the front side and the rear side of the isolation frame, the tops of the storage barrels are connected and communicated with the feeding pipe, and the spraying pipe is connected with the dust cover. A dustproof cover covers the feeding pipe, the top of the storage
barrel is connected and communicated with a connecting pipe, a water pump is arranged on the connecting pipe, one end of the connecting pipe is connected and communicated with a spraying pipe, and the right side of the isolation frame is fixedly connected with a spraying pipe. The redundant or unabsorbed
pigment can fall to the bottom of the isolation frame through the reserved groove holes in the conveying
assembly, due to the fact that the bottom of the isolation frame is designed in an inclined mode, the redundant pigment can flow into the collecting frame to be recycled, follow-up pigment treatment is facilitated, and waste of the pigment is avoided.
