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.

First claim

The invention claimed is:

1. A dyeing device of a smear machine, comprising:
a dyeing tank;
a transmission mechanism for transmitting the dyeing tank circularly in an enclosed delivery channel; and
a work position arranged in the enclosed delivery channel, wherein the work position comprises:
a blocking and separating mechanism that blocks a dyeing tank to be treated in a current work position and separates a treated dyeing tank so as to transmit a separated dyeing tank to a next work position along the enclosed delivery channel by the transmission mechanism;
a reagent supplying and discharging mechanism that injects and/or discharges a reagent to/from the dyeing tank; and
a driving mechanism for driving the blocking and separating mechanism;
wherein the dyeing tank comprises a body; the body is equipped with an opening cavity for accommodating a reagent and a smear; and both sides of the body are equipped with a suspension end for suspending the dyeing tank on the transmission mechanism; wherein the suspension end is equipped with a slot for separation by the blocking and separating mechanism.

2. The dyeing device of claim 1 , wherein the transmission mechanism comprises a round tray driven by a motor, and the round tray is supplied with an annular opening for suspending the dyeing tank.

3. The dyeing device of claim 1 , wherein the blocking and separating mechanism comprises a claw arm that is linked with the driving mechanism; the claw arm is driven to move by the driving mechanism; and the claw arm comprises a blocking part, a separating part, and a linking part for fixedly connecting the blocking part and the separating part; wherein the blocking part and the separating part are driven by the driving mechanism to be alternately located in the enclosed delivery channel of the dyeing tank, and the blocking part and the separating part are set front and back in the channel along a direction of transmitting the dyeing tank by the transmission mechanism.

4. The dyeing device of a smear machine of claim 3 , wherein the dyeing device of a smear machine can comprise two claw arms, and the blocking part and the separating part of each claw arm are set on both sides of a target dyeing tank; wherein the blocking parts of the two claw arms are both set in a front orientation along a direction of transmitting the target dyeing tank, and the separating parts of the two claw arms are both set in a rear orientation along the direction of transmitting the target dyeing tank.

5. The dyeing device of claim 1 , wherein each work position also comprises a detection device that detects a position of the dyeing tank and connects with the driving mechanism; and the dyeing tank also comprises a position detection plate for detection.
