Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, and in particular to a labeling position adjustment mechanism for a carton labeling machine. Background Technology

[0002] Cardboard boxes are a type of packaging material widely used in product packaging. Labels containing product and production information need to be affixed to these boxes. Currently, the labeling machine is fixed in a fixed position, and an unlabeled cardboard box is transported by a conveyor belt. When the unlabeled cardboard box moves to a position below the labeling machine, it stops, and the labeling machine can then apply the label. In this labeling method, the position of the labeling machine is fixed. To improve the accuracy of the labeling position, the position of the cardboard box must be precise when it stops below the labeling machine. However, the existing method of using a conveyor belt to transport the cardboard box cannot guarantee the accuracy of the stopping position.

[0003] A carton labeling machine, authorized under publication number CN220786408U, includes a carton and a base arranged opposite each other. The upper end of the base has oppositely arranged side plates, and a conveyor belt that cooperates with the carton is located between the two side plates. The upper end of each side plate has a labeling machine body that cooperates with the carton, including a guide structure and a partition structure. The guide structure includes at least one L-shaped rod evenly arranged on the upper end of each side plate. One end of each L-shaped rod is fixed to a crossbar, and the lower end of each crossbar has at least one evenly arranged rotating shaft. The lower end of each rotating shaft has a guide roller that cooperates with the carton. The partition structure includes a buffer plate and oppositely arranged side grooves within the labeling machine body. Each side groove contains a shaft driven by a motor. The advantage of this invention compared to existing technologies is that it ensures the accuracy of the carton's stopping position below the labeling machine, thereby improving labeling accuracy.

[0004] Regarding the aforementioned technologies, the existing labeling machines have the following drawbacks: during use, the labeling position adjustment device only clamps and limits the carton through the limiting device. However, the dust adhering to the surface of the carton during the conveying process acts as a "lubricant" between the carton surface and the clamping device (such as mechanical claws or clamps), which significantly reduces the static friction of the contact surface, which may lead to misalignment and affect labeling. Therefore, this utility model provides a labeling position adjustment mechanism for a carton labeling machine. Utility Model Content

[0005] The purpose of this application is to provide a labeling position adjustment mechanism for a carton labeling machine, in order to solve the problem mentioned in the background art that the dust adhering to the surface of the carton during the conveying process is equivalent to the "lubricant" between the surface of the carton and the clamping device (such as mechanical claws or clamps), which will significantly reduce the static friction of the contact surface, may cause misalignment, and affect the labeling problem.

[0006] To achieve the above objectives, this application provides the following technical solution: a labeling position adjustment mechanism for a carton labeling machine, including a support frame, a conveying device disposed on the outer side of the support frame, a support frame and a positioning frame disposed sequentially on the outer side of the support frame, and a charge imparting component disposed on the outer side of the support frame; the charge imparting component includes a high-voltage DC power supply fixedly connected to the outer side of the support frame, an energizing plate disposed on the inner wall side of the support frame, and uniformly distributed metal needle-shaped electrodes electrically connected to the outer side of the energizing plate; the output terminal of the high-voltage DC power supply is electrically connected to the energizing plate; and a dust adsorption component is disposed on the outer side of the positioning frame.

[0007] Preferably, the dust adsorption assembly includes a sliding frame slidably connected to the side of the positioning frame, a threaded rod rotatably connected to the inner wall of the sliding frame, a slider threadedly connected to the outer side of the threaded rod, a rubber block fixedly connected to the outer side of the slider, and a metal mesh plate fixedly connected to the outer side of the rubber block.

Furthermore, through the cooperation of a hydraulic telescopic rod and a sliding frame, the height of the metal grid plate can be adjusted to accommodate cartons of different heights, thereby reducing the impact of dust on clamping accuracy and labeling.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1: Reference Figure 1-4 The labeling position adjustment mechanism of the carton labeling machine shown in this application includes a controller and a power supply. The controller controls electrical components (such as motors and telescopic hydraulic cylinders), and the power supply provides power. It also includes an oil supply mechanism for the hydraulic cylinders, which is existing technology and will not be described in detail here. The mechanism includes a support frame 1, which stably supports the core components of the entire mechanism, ensuring structural stability during operation. A conveying device 2 is located on the outer side of the support frame 1, used to transport the cartons to be labeled to the designated processing position, enabling continuous production. A support frame 14 and a positioning frame 7 are sequentially arranged on the outer side of the support frame 1. The support frame 14 provides an installation foundation for the charge-applying component and ensures its positional stability. The positioning frame 7 is used to install and fix the dust adsorption component, ensuring accurate positioning during adsorption. A charge-applying component is located on the outer side of the support frame 14. The charge-applying component includes a high-voltage DC power supply 15 fixedly connected to the outer side of the support frame 14, which provides a stable high-voltage power output to the charge-applying component. An energizing plate 18 is located on the inner wall side of the support frame 14, used to conduct high-voltage current and provide an installation carrier for the metal needle-shaped electrodes 16. The outer side of the circuit board 18 is electrically connected to uniformly distributed metal needle-shaped electrodes 16, which generate corona discharge under the action of high voltage, ionizing the surrounding air and imparting electrostatic charge to the surface of the cardboard box, thereby enhancing the subsequent dust adsorption effect. The output terminal of the high-voltage DC power supply 15 is electrically connected to the circuit board 18. A dust adsorption component is provided on the outer side of the positioning frame 7. The dust adsorption component includes a sliding frame 20 slidably connected to the side of the positioning frame 7, which can slide laterally along the positioning frame 7 to adjust the lateral position of the dust adsorption component to adapt to cardboard boxes of different sizes. The inner wall of the sliding frame 20 can rotate. A threaded rod 22 is connected, and the slider 23 is rotated to achieve longitudinal displacement. The slider 23 is threadedly connected to the outside of the threaded rod 22. Under the drive of the threaded rod 22, the rubber block 17 and the metal grid plate 10 move longitudinally to adjust the adsorption height. The rubber block 17 is fixedly connected to the outside of the slider 23 to buffer and absorb shock, and to prevent the metal grid plate 10 from colliding hard with other components. The metal grid plate 10 is fixedly connected to the outside of the rubber block 17, and uses the principle of electrostatic adsorption to adsorb dust and impurities on the surface of the carton, ensuring that the labeling surface is clean and improving the labeling quality.

[0024] Example 2: Reference Figure 1-4 Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a motor 21 is fixedly connected to the inner wall side of the sliding frame 20. The motor 21 serves as a power source, and its output end is fixedly connected to the threaded rod 22, driving the threaded rod 22 to rotate. The slider 23 is slidably connected to the inner wall side of the sliding frame 20. The rotation of the threaded rod 22 causes the slider 23 to move linearly along the inner wall of the sliding frame 20, achieving precise control of the position of the slider 23. A hydraulic telescopic rod 19 is fixedly connected to the inner wall side of the positioning frame 7. The hydraulic telescopic rod 19 provides linear driving force, and its output end is fixedly connected to the sliding frame 20, pushing the sliding frame 20 to reciprocate linearly within the positioning frame 7 to adjust the position of the sliding frame 20. A T-shaped limiting block 8 is fixedly connected to the outer side of the sliding frame 20, and a groove 9 adapted to the limiting block 8 is provided on the outer side of the positioning frame 7. The T-shaped limiting block 8 cooperates with the slide groove 9 to constrain the movement trajectory of the sliding frame 20, preventing it from deviating during movement and ensuring its stability. A vibration motor 11 is installed on the outer side of the sliding frame 20, serving as the vibration source. Its output end passes through the sliding frame 20, and a vibration head 12 is fixedly connected to the output end of the vibration motor 11. When the vibration motor 11 operates, it drives the vibration head 12 to generate high-frequency vibration for vibration treatment of specific objects. A collection frame 13, adapted to the metal mesh plate 10, is installed on the inner side of the sliding frame 20, located below the vibration head 12. The metal mesh plate 10 absorbs dust, while the collection frame 13 collects materials that fall from the metal mesh plate 10 after vibration treatment. A fixing frame 3 is fixedly connected to the outer side of the support frame 1, providing support and fixation for the labeling device 6 and the hydraulic push rod 4. The labeling device 6 is installed on the outer side of the fixing frame 3 for labeling products. Hydraulic push rods 4 are installed through both ends of the fixed frame 3, and push plates 5 are fixedly connected to the output ends of the hydraulic push rods 4. The hydraulic push rods 4 push the push plates 5 to make linear movements, which are used for positioning or pushing the product.

[0025] The working principle of this utility model is as follows: The cardboard box is conveyed by the conveying device 2 until it reaches below the metal needle electrode 16. The tip of the metal needle electrode 16 generates a corona discharge, ionizing air molecules into positive / negative ions. Dust particles become charged upon contact. The conveying device 2 continues to convey the cardboard box until it reaches below the metal grid plate 10. The charged dust particles are attracted to the grounded metal grid plate 10 by the electric field (opposites attract), thus separating from the cardboard box. The hydraulic telescopic rod 19 drives the sliding frame 20 and the limiting block 8 to slide along the slide groove 9, adjusting the height of the metal grid plate 10 to accommodate different heights. The cardboard box is made of thinner material to reduce the impact of dust on the labeling operation. The control conveyor 2 drives the cardboard box to continue moving, and the control hydraulic push rod 4 drives the push plate 5 to move, limiting the position of the cardboard box so that it will not deviate. The labeling device 6 applies labels to the cardboard box. The control motor 21 drives the threaded rod 22 to rotate, and the slider 23 drives the rubber block 17 and the metal grid plate 10 to move, so that the metal grid plate 10 moves above the collection frame 13. The control vibration motor 11 drives the vibration head 12 to vibrate. With the cooperation of the rubber block 17, the metal grid plate 10 vibrates at high frequency, shaking off the dust. The collection frame 13 collects the dust.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
