  • Dyeing device and method of using a paddle dyeing machine
    Patent number: 9612180
    Abstract: A dyeing device of a smear machine may include a dyeing tank, a transmission mechanism and a work position set in an enclosed delivery channel of the transmission mechanism. The work position may include a blocking and separating mechanism, a reagent supplying and discharging mechanism, and a driving mechanism for driving the blocking and separating mechanism. The blocking and separating mechanism can operate for blocking a dyeing tank to be treated in a current work position, separating a treated dyeing tank and transmitting a separated dyeing tank to a next work position along the enclosed delivery channel. The reagent supplying and discharging mechanism can inject and/or discharge reagent into/from the dyeing tank. Various embodiments of this disclosure can transmit the dyeing tank within the enclosed transmission channel, block and separate the dyeing tank in the work position, and inject/discharge the dyeing solution into/from the dyeing tank as needed.
