Since gaskets are arranged on both sides of the movable plate 14, the quantum dot colloid will not flow downward during the pushing process. When the height of the quantum dot colloid completely covers the discharge pipe 23, the second motor 19 is started to drive the screw rod 20 to rotate again, so that the third slider 21 above the screw rod 20 drives the baffle 22 to slide inside the body 1, and then the discharge pipe 23 is opened. At this time, the quantum dot colloid flows into the glass tube 24, and the quantum dot colloid is squeezed into the glass tube 24 by the action of the internal pressure until the interior of the glass tube 24 is filled with quantum dot colloid to achieve encapsulation, and the discharge pipe 23 is closed again at this time.
