Varnishing (Sealing-Laquering) Machine

The primer pocket and case sealing machine utilize a sophisticated system, integrating servo motor and pneumatic controls. This system facilitates the injection of sealing liquid into the primer pocket and case, which are positioned on the feeding conveyor by the operator within a rotational feeder.The operator feeds the casings onto the feeding conveyor. The conveyor moves upwards and discharges the loaded casings into the rotational feeder. The fullness of the rotational feeder is checked by the sensor inside the rotational feeder. With the rotation of the rotational feeder, the casings go up and fall into the ring lines. Sensors in the ring lines check the fullness of the line. If the line is filled, the line is closed with the help of blowers. The casings passing through the ring line descend to the feeder actuator. The feeder actuator brings the casings to the position suitable for lacquering. The casings in the appropriate position are brought to the position to be pushed into the rotating tambour by the casing slider piston and while in this position, the casing inserter piston pushes the casings into the rotating tambour. After the casings are inserted into the rotating tambour, the casing sensors check the presence of the casings, and the tambour rotates 1 turn. Then sealing liquid is injected into the primer pocket and case mouth of the casings. After completing the round, the casings are pushed down towards the exit conveyor with the help of the casing unloader piston. Fans on the top of the conveyor allow the sealing liquid injected into the casings to dry. The dried casings fall from the end of the exit conveyor.
