Description

Technical Field

[0001] The utility model relates to the technical field of carton labeling, in particular to a labeling device for corrugated carton production. Background Art

[0002] A labeling machine is a device that uses adhesive to attach paper or metal foil labels to specified packaging containers. It is a basic industrial device in the field of commodity packaging. Although there are many types, the overall principle is roughly the same. That is, when the sensor sends a signal that the label object is ready to be labeled, the drive wheel on the labeling machine rotates. Since the roll label is in a tensioned state on the device, when the backing paper changes direction against the peel plate, the front end of the label is forced to detach due to its own rigidity and prepare for labeling. At this time, the label object is just under the label. Under the action of the labeling wheel, synchronous labeling is achieved. After labeling, the sensor under the roll label sends a stop signal, the drive wheel stops, and a labeling cycle ends.

[0003] However, the peeling plates or peeling rollers of existing corrugated box labeling devices generally have the following technical problems in actual production scenarios:

[0004] Generally speaking, the peeling roller plays two core roles in the labeling device. The first role is to guide the labeling paper that has not been separated from the paper label to the surface close to the carton. The second core role is more critical, that is, to use the basic property that the hardness of the label is greater than the hardness of the base paper. When the base paper tape uses the peeling roller as the turning angle node and turns 170 degrees with the vector direction of the label speed, the base paper and the label will be perfectly separated. However, there is a key problem in the middle, which is the distance between the peeling roller and the upper surface of the carton. If the peeling roller is too high from the upper surface of the carton, at this time, although the lower end of the label can contact the carton and be captured However, the gap between the upper part of the label and the carton will be larger. When the upper part of the label tape is gradually pressed against the surface of the carton, it is easy to cause air to be sealed in the label, resulting in uneven labeling such as steam bubbles and bulges. On the contrary, if the peeling roller is too low from the upper surface of the carton, or even has a certain degree of squeezing or interference, the carton running at high speed on the conveyor belt may be squeezed or worn in this case, or even blocked by the peeling roller and unable to flow down. Therefore, each time the labeling device is used to package goods of different heights, the various parameter settings in the labeling device need to be carefully adjusted, which is very inconvenient to use.

[0005] In summary, a labeling device for corrugated box production is proposed. Utility Model Content

[0014] 1. The utility model can control a closer distance between the lower end of the peeling plate and the carton surface through the height adjustment mechanism. In this way, when the label contacts the carton surface from the bottom end to the top end of the label completely falls into the carton surface, the gap of the entire label is controlled within the minimum range, so that the label and the carton are closer when labeling, so that the label is more tightly attached, and it is not easy to bulge due to air intrusion, making the labeling smoother.

[0015] 2. The utility model uses a spring rod assembly provided in the height adjustment mechanism to ensure that the lower end of the stripping plate is at the optimal distance, that is, the closest distance, from the optimal carton surface. A critical situation may occur, that is, the lower end of the stripping plate is in slight contact with the carton. When a slight friction collision occurs during the movement of the carton, the stripping plate can swing with the fixed rod as the center and the arc limit groove as the trajectory, and the spring can buffer the swinging swing rod, thereby avoiding interference between the lower end of the stripping plate and the upper surface of the carton, making the carton movement more stable.

[0024] The height adjustment mechanism includes a limit platform 7 fixedly connected to one side of the two mounting plates 2, and a slot 8 is provided on the two limit platforms 7. The inner sides of the two slots 8 are slidably connected with sliders 6. The sliders 6 are T-shaped block mechanisms. The upper sides of the two sliders 6 are fixedly connected to the limit frames 9. The limit frames 9 are long strips with hollowed-out limit grooves inside. The width of the limit grooves is the same as the diameter of the rocker arm 3. The two ends of the rocker arm 3 are respectively slidably connected to the inner sides of the two limit frames 9. Through the above-mentioned technical solution, the rocker arm 3 can only move within the restricted space of the arc limit groove 10 and the limit frame 92 motion trajectories. The inner sides of the two limit platforms 7 are provided with spring rod assemblies for buffering the movement of the sliders 6.

[0025] Please combine Figure 1 As shown, the spring rod assembly includes two slide rods 4 fixedly connected to the inner sides of the two card slots 8, each slide rod 4 is slidably connected to the slider 6, and a spring 5 is respectively provided between the two sides of each slider 6 and the inner side of the corresponding card slot 8. Each spring 5 is sleeved on the outer side of the slide rod 4. Through the above technical solution, when the rocker arm 3 is touched by the carton and fluctuates, it can be converted into elastic potential energy on the spring 5, thereby achieving a buffering effect.

[0026] Please combine Figure 3 As shown, the label feeding mechanism includes a label roll 14 rotatably connected between the two mounting plates 2 , and the highest point of the label roll 14 and the highest point of the peeling plate 12 are located at the same horizontal plane.

[0027] Please combine Figure 3As shown, the bottom paper recovery mechanism includes a buffer roller 16 and a paper receiving reel 15 which are rotatably connected to the two mounting plates 2 respectively. Elastic components for buffering the buffer roller 16 are provided at both ends of the buffer roller 16. When the stripping plate 12 swings, the buffer roller 16 can adjust the tensioning posture of the paper tape to play a protective role. The buffer roller 16 is adjacent to the lower side of the stripping plate 12. A drive motor 13 is fixedly connected to one side of one of the mounting plates 2.

The labeling roller assembly 17 is composed of a laser rangefinder sensor, a labeling roller, a servo motor, a card block, a card slot and a threaded rod. The laser rangefinder sensor is responsible for detecting the movement of the carton and sending a signal to the servo motor, which controls the lifting height of the labeling roller through the servo motor.

[0029] The implementation principle of a labeling device for corrugated box production in the embodiment of the present application is as follows: the user loads the self-adhesive label into the label roll 14 position, the label paper tape passes through the fixed rod 11, and moves downward along the upper side of the peeling plate 12, then turns to the back side of the peeling plate 12 through the swing rod 3, passes the highest point on the upper side of the buffer roller 16, and enters the paper delivery roll 15. When the drive motor 13 is started, the label paper tape pulls the label roll 14 to rotate. When the label paper tape flows through the swing rod 3, that is, the lower end of the peeling plate 12, due to The stiffness of the label's own material is greater than that of the backing paper tape, so the label continues to advance, while the paper tape is successfully separated. When the lower end of the label is captured by the carton on the conveyor belt 1, the label can be initially attached to the carton label due to its own adhesive. At this time, the relative speed of the label is the same as the forward speed of the carton. After the initial labeling is completed, the carton is immediately detected by the sensor of the adjacent labeling roller assembly 17. The control component on the labeling roller assembly 17 sends a signal to lower the height of the pressure roller to further flatten the label.
