Control principle of rotary bottle labeling machine

The running route of the bottle from entering to leaving the labeling machine is similar to the running route of the filling machine mentioned above. Bottles are sent from the bottle conveying belt to the bottle stop star wheel. The locked bottle stop star wheel is stuck, and the bottle conveying belt continues to run, which gradually increases the number of blocked bottles. The bottles cannot move forward and can only be arranged on both sides of the conveyor belt. , There are side boards on both sides of the bottle conveyor belt, and the side boards are equipped with induction switches. As the increase of bottles presses the side plate to touch the induction switch, an electric signal is generated to open the solenoid valve for ventilation. The compressed air unlocks the cylinder that locks the bottle star wheel. The bottle stop star wheel and the side plate work together to allow the bottles to pass and transport in a single row. To the bottle feeding screw; the container is fed into the bottle star wheel by the bottle feeding screw, and the bottle feeding star wheel cooperates with the center guide plate to change the direction of the bottle and send the bottles to the bottle turret at equal intervals. The bottle turret is by the bottle holder It is composed of two parts and fixed bottle assembly.
When the bottle enters the bottle tray on the bottle table, the bottle pressing head of the bottle fixing assembly just presses the top of the bottle cap under the action of the bottle pressing star wheel, and rotates concentrically with the bottle tray to send the bottle to the labeling Station. Since the bottle tray is tangent to the position of the label holder drum at this time, the bottle is stuck with label paper at this position, and the sticking area is small. The label paper is located in the tangential direction under the bottle holder. As the bottle holder rotates, the bottle is on the bottle tray. The upper and the bottle pressing head rotate 90° clockwise together, so that the unadhered part of the label paper passes through the marking station. The brush can smoothly brush the label paper on the container wall. Of course, there is also a counterclockwise rotation to stick the bottle label. The other side of the paper is also brushed with a brush. Through this swing, the label is brushed flat and stuck. When the labelled bottle reaches the bottle star wheel, the bottle pressing head is raised under the action of the lifting cam to relieve the pressure on the bottle, and the bottle is output through the bottle star wheel.
