The beginning of the working process of the automatic labeling machine is that the box is fed to the labeling machine at a constant speed on the conveyor belt. The mechanical fixing device separates the boxes by a fixed distance and pushes the boxes along the conveyor belt. The mechanical system of the labeling machine includes a driving wheel, a labeling wheel, and a reel. The driving wheel drags the label tape movement intermittently, the label tape is pulled out from the reel, and the labeling wheel will press the label tape on the box after passing through the labeling wheel. An open-loop displacement control is used on the reel to maintain the tension of the label tape. Because the labels are closely connected to each other on the label tape, the label tape must constantly start and stop. The label is affixed to the box when the labeling wheel moves at the same speed as the box. When the conveyor belt reaches a certain position, the label belt drive wheel will accelerate to a speed that matches the conveyor belt, and after the label is attached, it will decelerate to a stop. Since the label belt may slide, there is a registration mark on it to ensure that each label is placed correctly. The registration mark is read by a sensor. During the deceleration phase of the label tape, the drive wheel will reposition to correct any position errors on the label tape. Another way of saying is: After the bottles enter the labeling machine, the stop star wheel will open after a certain number of bottles. The bottles are carried forward by the conveyor belt and enter the bottle feed star wheel after the bottle feed screw is fixed. When entering the bottle holder, the bottle pressing head moves downward under the action of the bottle pressing cam, pressing the bottle, and reaching the first labeling station. At the same time, the cylinder pushes the label box forward. After the label is taken and the rubber roller is rolled and glued, a piece of label paper is removed from the label box. When the label drum clamps the label paper and turns to the bottle to be tangent, the label paper is attached to the bottle. After labeling, the bottle holder rotates a certain angle under the action of the cam, and the bottle holder rotates clockwise while revolving. At 90 degrees, when the bottle passes through the area equipped with the brush, the label paper is swiped by the brush. In order to make the capping label paper can be brushed by the brush, the pallet bottle revolves through the top label brush area at the same time. Rotate clockwise and counterclockwise. When it goes to the labeling position of the second station, the back of the bottle is tangent to the label-holder drum. At this time, the back label can be applied, and the back label will be applied by the autorotation of the bottle tray. Paper brush clothes.
