Description

Technical Field

[0001] This utility model relates to the field of cardboard box labeling technology, and in particular to a multi-station labeling device for cardboard boxes. Background Technology

[0002] To achieve product identification, information traceability, warehouse management, and efficient logistics sorting, labels containing product information, logistics barcodes, addresses, and other information are accurately and firmly affixed to designated locations on cartons using automated equipment or manual methods. Modern labeling is usually completed automatically by labeling machines, which ensures that the labels are flat, bubble-free, and uniformly positioned, thereby significantly improving operational efficiency and accuracy. This is an indispensable standardized operating procedure for e-commerce, manufacturing, and logistics industries. The carton labeling device includes an unwinding and rewinding mechanism for carrying and retrieving the label backing paper. It smoothly pulls the label, uses a peeling plate to separate the label from the backing paper, and the labeling head accurately presses the separated label onto the surface of the carton, achieving efficient and accurate automated labeling. In existing technologies, the labeling head of conventional carton labeling devices cannot rotate and cannot flexibly adjust its angle to fit various types of cartons. When encountering uneven carton surfaces, slopes, or irregular shapes, the labels cannot be fully adhered, resulting in wrinkles, curling corners, or even air bubbles, which seriously affects the label's durability and appearance. Furthermore, when the carton slightly shifts or tilts on the conveyor line, it cannot adaptively adjust, easily leading to defects such as inaccurate labeling positions or crooked labeling. Therefore, a multi-station labeling device for cartons is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a multi-station labeling device for cartons, which aims to improve the problem that the labeling head in the prior art cannot rotate and cannot flexibly adjust the angle to fit various types of cartons.

The rotating mechanism includes a base block, the rear end of which is mounted on the front end of the labeling roller plate. A pressing component is fixedly connected to the top end of the base block, and a fixing block is fixedly connected to the bottom end of the pressing component. A locking rod is fixedly connected inside the fixing block, and a rotating rod is slidably connected to the outside of the locking rod. A label pressing plate is fixedly connected to the outside of the rotating rod.

[0005] As a further description of the above technical solution: The replacement mechanism includes a fixed rod, the front end of which is fixedly connected to the rear end of the adjusting rod. Multiple bent plates are fixedly connected to the inner side of the fixed rod, and fixed blocks are fixedly connected to both ends of the multiple bent plates. A grooved rod is engaged with the inner side of the fixed blocks, and a guide mold is rotatably connected to the rear end of the grooved rod.

[0006] As a further description of the above technical solution: The pressing assembly includes a spring, the bottom end of which is fixedly connected to the top end of the base block, a pressing plate is fixedly connected to the top end of the spring, and two connecting rods are fixedly connected to the bottom end of the pressing plate.

[0007] As a further description of the above technical solution: The top end of the fixing block is fixedly connected to the bottom end of the connecting rod, and the outer side of the connecting rod is slidably connected to the inside of the base block.

[0008] As a further description of the above technical solution: The outer side of the rotating rod has multiple round holes, and the round end of the locking rod is locked inside the round holes of the rotating rod.

[0009] As a further description of the above technical solution: The bottom end of the pressing component contacts the top end of the base block, and the bottom end of the base block contacts the top end of the fixing block.

[0010] As a further description of the above technical solution: The outer side of the lever is slidably connected to the inside of the base block, and the outer side of the rotating rod is rotatably connected to the inside of the base block.

[0011] As a further description of the above technical solution: The front end of the guide mold is mounted on the rear end of the fixing rod, and the fixing rod is concave.

[0012] This utility model has the following beneficial effects: 1. In this utility model, the user presses the component to disengage the locking rod, allowing the rotating rod to rotate freely within the base block to the desired angle. Then, the spring rebounds to quickly reset and lock the locking rod, significantly improving the adaptability of the labeling head to cartons of different shapes, ensuring that the labels are applied smoothly and without bubbles, and greatly improving the labeling quality and efficiency.

[0013] 2. In this utility model, by rotating the groove rod at the front end of the guide mold, the inclined groove of the guide mold cooperates with the inclined surface of the fixed block two to squeeze the elastic bent plate, causing it to expand outward, thereby unlocking and removing the mold.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0017] Multi-station labeling device for cartons, see reference Figures 1 to 3The system includes a conveyor belt 1, which provides continuous power for carton conveying and ensures the orderly connection of the labeling process. A labeling roller 2 is installed at the rear end of the conveyor belt 1. The labeling roller 2 controls the label tension through multi-roller coordination to ensure smooth label conveying. A rotating mechanism 4 is installed at the front end of the labeling roller 2. The rotating mechanism 4 can flexibly adjust the label pressing angle to improve the labeling fit. An adjusting rod 3 is installed at the front end of the conveyor belt 1. The adjusting rod 3 can precisely fine-tune the position of the components to adapt to different sizes of cartons. A replacement mechanism 5 is installed at the rear end of the adjusting rod 3. The replacement mechanism 5 facilitates quick switching of guide components and enhances the versatility of the device. Specifically, the conveyor belt 1 circulates and transports cartons, providing a continuous rhythm for labeling and ensuring uninterrupted process flow. The labeling roller 2 at the rear of the conveyor belt 1 rotates synchronously through the roller body to stably transport labels and control tension to prevent wrinkles. The front rotating mechanism 4 can drive the label pressure plate to rotate and adjust the angle, allowing the label to adhere tightly to the surface of the carton. The front adjusting rod 3 of the conveyor belt 1 can extend and retract for fine adjustment. The rear changing mechanism 5 can quickly disassemble and assemble the guide mold 52, flexibly adapting to the processing needs of cartons of different sizes. The rotating mechanism 4 includes a base block 41, which provides a stable mounting reference for each component of the rotating mechanism 4, ensuring precise operation. The rear end of the base block 41 is installed at the front end of the labeling roller plate 2, realizing a rigid connection between the rotating mechanism 4 and the labeling roller plate 2, preventing shaking during operation. A pressing component 42 is fixedly connected to the top of the base block 41. The pressing component 42 is a convenient trigger component for angle adjustment, which saves effort during operation. A fixing block 43 is fixedly connected to the bottom end of the pressing component 42. The fixing block 43 can evenly transmit the pressing power, ensuring effective force transmission. A locking rod 44 is fixedly connected inside the fixing block 43. A rotating rod 45 is slidably connected to the outside of the locking rod 44. The locking rod 44 fixes the position of the rotating rod 45 through a locking action, ensuring angle stability. A label pressure plate 46 is fixedly connected to the outside of the rotating rod 45. The rotating rod 45 can drive the label pressure plate 46 to rotate, realizing flexible adjustment of the labeling angle. The label pressure plate 46 directly presses down on the label, promoting a tight fit between the label and the carton. Specifically, the base block 41 provides stable support for each component of the rotating mechanism 4, ensuring precise and error-free subsequent adjustment actions. The pressing component 42 on the base block 41 serves as the core trigger for angle adjustment. A light press can link the subsequent components, making operation effortless and responsive. The pressing component 42 drives the fixed block 43 to move, and the fixed block 43 transmits power evenly to the locking rod 44. The locking rod 44 locks the position of the rotating rod 45 by engaging, ensuring a stable labeling angle. The rotating rod 45 can drive the label pressure plate 46 to rotate flexibly. After adjusting to the appropriate angle, the label pressure plate 46 can accurately press down on the label, allowing the label to adhere tightly to the surface of the carton and preventing air bubbles or curling edges. The pressing assembly 42 includes a spring 423, which provides automatic reset power to the pressing plate 421 to ensure reliable engagement. The bottom end of the spring 423 is fixedly connected to the top end of the base block 41, providing stable support for the deformation of the spring 423 and ensuring uniform rebound force. The top end of the spring 423 is fixedly connected to the pressing plate 421, which provides a comfortable force application point for the operator and ensures smooth pressing action. The bottom end of the pressing plate 421 is fixedly connected to two connecting rods 422, which are symmetrically distributed and have... The moving fixed block 43 moves smoothly. The top of the fixed block 43 is fixedly connected to the bottom of the connecting rod 422 to achieve lossless power transmission. The outer side of the connecting rod 422 is slidably connected to the inside of the base block 41 to limit the movement trajectory of the connecting rod 422 and ensure precise action. The outer side of the rotating rod 45 has multiple round holes, which provide multiple engagement points for the locking rod 44 to meet different angle requirements. The round end of the locking rod 44 is locked inside the round hole of the rotating rod 45. The round end design makes it easy to engage and disengage, improving adjustment efficiency. Specifically, the spring 423 of the pressing component 42 is compressed and stores force when the pressing plate 421 is subjected to force. When it rebounds, it can output a stable and controllable force to push each component to accurately reset, ensuring that the locking rod 44 and the rotating rod 45 are firmly engaged and do not loosen. The surface of the pressing plate 421 is smooth and easy to apply force. The operator can push the symmetrical connecting rod 422 at the bottom end to move synchronously down along the inner wall of the base block 41 with a light press, avoiding the fixed block 43 from shifting under force. The connecting rod 422 smoothly transmits the pressing power to the fixed block 43, driving the locking rod 44 to move synchronously. The round end of the locking rod 44 fits tightly with the round hole of the rotating rod 45. When it is engaged, it can fit firmly and prevent shaking. When it is disengaged, the resistance is small and the effort is less. The multiple round holes on the outside of the rotating rod 45 are evenly distributed at an angle, providing multiple adjustment points for the locking rod 44, so that the angle of the label pressing plate 46 can be adapted to different carton curvatures, greatly improving the labeling adaptability and adjustment efficiency. The bottom end of the pressing component 42 contacts the top end of the base block 41 to assist in positioning the pressing component 42 and enhance installation stability. The bottom end of the base block 41 contacts the top end of the fixing block 43 to limit excessive displacement of the fixing block 43 and protect the components. The outer side of the locking rod 44 is slidably connected to the inside of the base block 41 to provide sliding guidance for the locking rod 44 and ensure precise engagement. The outer side of the rotating rod 45 is rotatably connected to the inside of the base block 41 to make the rotating rod 45 rotate smoothly and reduce adjustment resistance. Specifically, the bottom of the pressing component 42 is attached to the top of the base block 41, forming a stable support when pressed, preventing the component from shaking and affecting the adjustment accuracy. The bottom of the base block 41 prevents the fixing block 43 from moving too high, preventing the components from being damaged by collision. The locking rod 44 slides along the inner wall of the base block 41, and the precise trajectory ensures quick alignment and engagement with the round hole of the rotating rod 45. The rotating rod 45 rotates within the base block 41 with low friction, making it easier and smoother to adjust the angle of the label pressure plate 46.

[0018] Reference Figure 2 and Figure 4The replacement mechanism 5 includes a fixed rod 51, which provides rigid support for all components of the replacement mechanism 5, ensuring a stable overall structure. The front end of the fixed rod 51 is fixedly connected to the rear end of the adjusting rod 3, enabling linkage between the replacement mechanism 5 and the adjusting rod 3 for easy position adjustment. Multiple bent plates 55 are fixedly connected to the inner side of the fixed rod 51, and fixed blocks 54 are fixedly connected to both ends of the multiple bent plates 55. A grooved rod 53 is engaged on the inner side of the fixed blocks 54. The bent plates 55 utilize elasticity to lock and release the grooved rod 53, simplifying the replacement operation. The grooved rod 53 facilitates mold assembly and disassembly. A guide mold 52 is rotatably connected to the rear end of the grooved rod 53. The guide mold 52 guides the carton to ensure accurate labeling. The front end of the guide mold 52 is installed at the rear end of the fixed rod 51, ensuring stable installation and preventing deviation during the guiding process. The fixed rod 51 has a concave shape to adapt to component installation requirements and optimize space layout. Specifically, the fixed rod 51 has a concave structure, which conforms to the contour of the component and provides rigid support, so that the entire replacement mechanism 5 is subjected to uniform force and does not wobble. When the adjusting rod 3 moves the fixed rod 51 back and forth, the fixed rod 51 can move all components synchronously, so that the guide mold 52 can be accurately adapted to the carton conveying position. The bent plate 55 on the inner side of the fixed rod 51 has good elasticity. When the groove rod 53 is squeezed, it will expand outward to store force. The fixed block 54 forms a ring-shaped clamping force on the groove rod 53, which has a good anti-loosening effect. Rotating the groove rod 53 can trigger the bent plate 55 to spring back and reset, and release the clamping for easy mold removal. The guide mold 52 connected to the groove rod 53 can standardize the carton conveying trajectory, so that the labeling surface of the carton is always aligned with the label. With the stable support of the fixed rod 51, there is no deviation in the guiding process, which greatly improves the labeling position accuracy.

[0019] The implementation principle of this application embodiment is as follows: the carton to be labeled is transported by the conveyor belt 1, the labeling roller plate 2 is equipped with multiple rollers for limiting and conveying and winding the label, the label is pressed down by the adjustable rotation mechanism 4 so that the label is better attached to the carton, the front end of the conveyor belt 1 is adjusted back and forth by the adjustment rod 3, and the guide mold 52 is detachable and replaceable by the replacement mechanism 5.

[0020] The user only needs to rotate and adjust by pressing the pressing component 42, pressing the pressing plate 421, causing the pressing plate 421 to move downwards, squeezing the spring 423 and causing the connecting rod 422 to move downwards. The connecting rod 422 drives the fixing block 43 downwards, bringing out the locking rod 44. At this time, the locking rod 44 disengages from the hole of the rotating rod 45. Rotating the label pressing plate 46 causes the rotating rod 45 to rotate inside the base block 41. After rotating to the appropriate position, the user releases the pressing plate 421, and the spring 423 rebounds, pushing the pressing plate 421 back, so that the locking rod 44 returns to the new hole, thus achieving angle adjustment.

[0021] To convey and guide different cartons, different guide molds 52 are required. At this time, rotate the groove rod 53 located at the front end of the guide mold 52 so that the inclined grooves on both sides of the groove rod 53 are on the other side of the inclined end of the second fixing block 54. Then, pull out the guide mold 52 directly so that the round edge of the groove rod 53 presses against the second fixing block 54. The second fixing block 54 causes the two sides of the bending plate 55 to expand outward. The bending plate 55 has a certain elasticity. The guide mold 52 can be removed directly. When installing a new guide mold 52, simply push the guide mold 52 in, squeeze the groove rod 53 into the bending plate 55, and rotate the groove rod 53 so that the inclined end is stuck on the edge of the second fixing block 54.
