Description

Technical Field

[0001] This utility model relates to a labeling machine, specifically a cardboard side labeling machine, belonging to the technical field of cardboard labeling machines. Background Technology

[0002] A labeling machine is a device that uses adhesive to affix paper or metal foil labels to specified packaging containers. It is an indispensable part of the modern packaging industry. Its working principle is as follows: a conveyor belt transports the object to be labeled to the labeling machine at a constant speed; a mechanical fixing device separates the object by a fixed distance and propels it forward along the conveyor belt; a sensor sends a labeling signal, and the drive wheel starts to rotate, pulling the label tape out of the reel; when the label tape passes the peeling plate, the label detaches from the backing paper due to its own material rigidity, ready for labeling; the labeling wheel presses the label onto the object while maintaining the same speed as the object; after the label tape drive wheel is applied, it decelerates and stops, while the sensor reads a registration mark to correct any positional errors.

[0003] Currently, labeling of the side panels of cardboard boxes is usually done using a labeling machine in an assembly line. During labeling, one roller of the labeling machine feeds the material, and the label is torn apart between two rollers. The conveyor belt is responsible for transporting the cardboard box, and an electric pusher pushes the label to the side of the cardboard box for pasting. The cardboard box moves on the conveyor belt. Before labeling, the labeling area on the side of the cardboard box is not cleaned. Some cardboard box side panels have debris from the cardboard box production process on the labeling area, which is not cleaned, affecting the fit of the label. Utility Model Content

[0004] The purpose of this invention is to provide a cardboard side labeling machine to solve the above problems. It is equipped with a cleaning mechanism to clean the labeling area on the side panel of the carton, so as to avoid paper scraps from affecting the fit of the label.

The end of the cylinder 204 is connected to a push plate 205 opposite to the mounting frame 301. When labeling, the label is placed on the winding reel 202. The label passes through the two pressure rollers 203. As the label is wound up, the label is separated from the adhesive paper. At this time, the cylinder 204 works to push the label onto the carton, completing the labeling operation.

[0027] In use, the motor 304 is powered on, causing the two rollers 302 to rotate, which in turn drives the conveyor belt 303 to rotate. The cartons to be labeled are placed at one end of the conveyor belt 303, and the cartons are conveyed towards one end of the motor 304, achieving continuous feeding of the cartons. In existing labeling equipment, a sensing mechanism is provided; when the cartons reach the designated position, it controls the conveyor belt 303 to stop and wait for labeling. During labeling, the cartons pass over the two pressure rollers 203. As the take-up reel 202 rotates, the label separates from the backing film between the two pressure rollers 203. At this time, the cylinder 204 is activated, pushing the pusher plate 205 forward to affix the label to the side panel of the cartons. Before labeling, the cartons... The paper scraps will pass through the suction head 408, which will suck up the debris from the labeling area of ​​the carton and put it into the corrugated pipe 407. It will then pass through the fixed box 405 and be isolated by the filter screen 410 at the bottom of the drawer 406. The air pump 401 is responsible for suction. After cleaning the side panel of the carton, it is beneficial to increase the fit of the label and avoid the label falling off due to the gap in the labeling. Pull the drawer 406 to separate it from the fixed box 405. Turn the screw 409 to raise and lower the suction head 408, which is beneficial to clean the carton according to different labeling positions. This will clean the paper scraps inside the drawer 406. The carton will also pass through the roller brush 502 during the conveying process to achieve carton pretreatment. After labeling, it will be automatically unloaded with the movement of the conveyor belt 303.
