How the Labeling Machine works
The beginning of the work process is that the bottle is fed to the labelling machine at a constant speed on the conveyor. The mechanical fixture separates the bottles a fixed distance and pushes the bottle in the direction of the conveyor. The mechanical system of the labeler includes a drive wheel, a labeling wheel, and a reel. The drive wheel intermittently drags the label belt to move, the label tape is pulled out of the spool, and the label wheel is pressed against the bottle by the labeling wheel. An open-loop displacement control is used on the reel to maintain the tension of the label strip. Since the labels are closely connected to each other on the label strip, the label strip must be constantly stopped of labeling machine.
The label is affixed to the box with the labeling wheel moving at the same speed as the bottle. When the conveyor reaches a certain position, the label drive wheel accelerates to match the speed of the conveyor, and after labeling, it decelerates to a stop of labeling machine.
Since the label may slip, it has a registration mark on it to ensure that each label is placed correctly. The registration mark is read by a sensor of labeling machine, and during the deceleration phase of the label, the drive wheel will be repositioned to correct any positional errors on the label strip.
Another way of saying this is: after the bottle enters the labeling machine, the bottle star wheel is opened after a certain number of bottles, the bottle is carried forward by the conveyor belt, and after entering the bottle screw of labeling machine, it enters the bottle star wheel, and then dials After entering the bottle table, the bottle head moves downward under the action of the pressure bottle cam, and presses the bottle to reach the first standard station of labeling machine.
At the same time, the cylinder pushes the label box forward, and after the labeling board and the rubber roller are glued, the label paper is removed from the label box, and then the clip of the label drum is taken off the label board, and the clip is taken of the labeling machine. When the standard drum is clamped to the bottle and the bottle is tangent, the label paper is attached to the bottle. After the labeling table is rotated by a certain angle by the cam, the tray is rotated clockwise while revolving of the labeling machine. 90 degrees, when the bottle passes through the area with the brush, the standard paper is brushed by the brush, so that the top label can be brushed by the brush, and the tray bottle is rotated several times while passing through the top brush area. Rotate clockwise and counterclockwise. When turning to the second station labeling position, the back of the bottle is tangent to the labeling drum. At this time, the back label can be attached, and then the rotation of the tray is carried out, and the back label is set by the brush. Paper brush clothing of the labeling machine.
