ABSTRACT:
A beaker for a sample dyeing machine comprises a hollow beaker body and a longitudinal sliding cylinder with flanges on both its ends. The outer wall of the cylinder is uniformly perforated for wrapping of a sample yarn or cloth to be dyed. A plurality of grooves is separately formed on the periphery of either one of the flanges to guide the flow of a dye solution. An annular passage is formed in the interior of the cylinder from one end to the other for allowing a dye solution to flow between the passage and the perforated wall of the cylinder. The beaker thus constructed can dye a sample uniformly and efficiently due to sufficient contact between a sample and a dye solution. The beaker also comprises a hollow tube outside the beaker body for one-way flow of a dye solution, and/or a dispensing device screwed on the top thereof for liquid addition to the beaker. A sample dyeing machine comprises a plurality of the beakers in a fixed rack. Under the rack is a magnetic plate having a plurality of strong magnets so separately arranged on the plate that the pole of each magnet is opposite to that of adjacent magnets. The cylinders inside the beakers are moved up and down by magnetic force while the magnetic plate is slid back and forth on a screw driven by a motor.
