Description

Technical Field

[0001] This utility model relates to the field of automated equipment technology for packaging production, and in particular to a high-speed labeling device for packaging. Background Technology

[0002] This device is a core automated piece of equipment in the midstream of the packaging production line. It is mainly installed on the critical labeling operation path from the completion of the material forming process to the warehousing stage. Through the integrated operation logic of high-speed and precise positioning, multi-specification adaptive clamping, flexible labeling protection, and efficient linkage control, it solves production problems such as labeling misalignment, material damage, and response lag caused by the mixing of multiple specifications of packaging materials, differences in shape, and high-speed conveying characteristics. At the same time, it reduces the intensity of manual intervention and production line downtime losses, ensures the continuous and efficient operation of the packaging production line, and avoids brand image damage, logistics traceability failure, and product quality risks caused by insufficient labeling accuracy and material damage. It is one of the key pieces of equipment for packaging manufacturing enterprises to achieve high-speed production and flexible transformation.

[0003] This high-speed labeling device for packaging is a core functional component of the mid-range material labeling process in the packaging production line. Its core function is to replace manual labor in the high-speed, precise positioning, stable clamping, and accurate labeling of various packaging materials, thus directly affecting the operating cycle, labeling accuracy, and material flow compliance of the packaging production line. Existing high-speed labeling devices for packaging often employ simplified designs with a single rigid clamping structure, fixed-stroke drive components, and decentralized detection modules. These designs can only achieve basic labeling functions and cannot meet the core production requirements of multi-specification adaptation, flexible clamping, high-speed response, and accurate labeling. This results in insufficient process adaptability, operational stability, and production economy, directly impacting the intelligent upgrading of enterprise production lines and the improvement of labeling efficiency. This is primarily reflected in poor multi-specification adaptability; the device is not specifically designed for the size differences and shape characteristics of packaging materials, leading to the mixing of different sizes and shapes of packaging. During production, manual replacement of specialized clamps or preset fixed program parameters is required, which is not only time-consuming but also prone to causing misalignment of gripping and clamping, resulting in a severe lack of adaptability. Furthermore, traditional devices use rigid clamping structures or single adsorption components, resulting in localized hard contact with packaging materials or uncontrollable adsorption force. They lack flexible buffering and gap filling designs. Excessive clamping or adsorption force can easily cause wrinkles and deformation of flexible packaging and indentations and scratches on the surface of rigid packaging. Insufficient clamping or adsorption force can easily cause material tilting and slippage during high-speed conveying, leading to labeling position deviations and directly affecting labeling accuracy and product appearance integrity. In addition, the existing devices have poor linkage between positioning detection and clamping and labeling actions, with delayed detection response and low operating accuracy of drive components. Under the high-speed production line cycle, detection, clamping, and labeling actions are prone to disconnection, resulting in increased rates of missed or incorrect labeling. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-speed labeling device for packaging, comprising a bracket and a high-speed adaptive positioning clamping labeling integrated assembly, wherein the high-speed adaptive positioning clamping labeling integrated assembly is disposed on the top of the bracket;

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] In the embodiments, please refer to the appendix. Figure 1 - Appendix Figure 2 As shown, this utility model provides a technical solution: a high-speed labeling device for packaging, including a bracket 100 and a high-speed adaptive positioning clamping labeling integrated component 500, wherein the high-speed adaptive positioning clamping labeling integrated component 500 is disposed on the top of the bracket 100;

[0026] according to Figure 1 As shown, a conveying assembly 200 and a labeling assembly 300 are respectively installed on the top of the support 100, and a packaged product 400 is movably placed on the top of the conveying assembly 200.

[0027] Specifically: First, two slide rails 501 are symmetrically fixed to both sides of the outer wall of the conveying assembly 200 with bolts, ensuring that the slide rails 501 are parallel to the central axis of the conveying assembly 200 and are securely installed; then, two fixing plates 502 are respectively fixed to one end of the outer wall of the two slide rails 501 with bolts, ensuring that the fixing plates 502 are perpendicular to the surface of the slide rails 501 and the spacing is adapted to the size of the connecting plate 503; then, the connecting plate 503 is fixed horizontally between the outer walls of the two fixing plates 502 with bolts, and finally, the laser position sensor 504 is installed on the connecting plate 503 with bolts. Inside of component 3, adjust the angle so that the sensor is directly aligned with the central axis of the conveying assembly 200, ensuring that the detection range covers the product conveying path; then, fix the two electric cylinders 505 to the other side of the outer wall of the two fixing plates 502 with bolts through the bracket 100. One end of the support block 506 is welded and fixed to the shaft end of the electric cylinder 505, and the other end is connected to the slider 507 with bolts. Assemble the slider 507 with the slide rail 501 with clearance fit, ensuring that the slider 507 slides smoothly along the slide rail 501 without jamming; then fix the metal plate 508 to the outside of each slider 507 with bolts. On one side of the wall, a miniature electric actuator 509 is horizontally installed on opposite sides of two metal plates 508 and fixed with bolts. The outer side of the elastic arc-shaped clamp 510 is bolted to the shaft end of the miniature electric actuator 509 to ensure that the clamp is installed flat and without tilting. Then, each set of guide plates 512 is symmetrically welded to the inner surface of the elastic arc-shaped clamp 510. The two ends of the spring 513 are welded and fixed to the inner surface of the guide plate 512 and the outer wall of the miniature adsorption chamber 514 respectively to ensure that the spring 513 can elastically extend and retract freely. Then, each set of miniature adsorption chambers 514 is connected to the guide plate 510 via the spring 513. 2. The elastic connection is achieved by connecting the negative pressure interface 515 at the top of the device to the external vacuum pump through a sealed pipe. The silicone adsorption ports 516 are evenly distributed on one side of the outer wall of the micro adsorption chamber 514 and are fixed with glue. Finally, four electromagnets 511 are embedded in the pre-reserved slots at the opposite ends of the two elastic arc-shaped clamps 510 to complete the overall assembly of the high-speed adaptive positioning clamping and labeling integrated component 500. The component is then bolted to the preset mounting position at the top of the bracket 100 to ensure that the labeling component 300 is located directly above the component, achieving precise alignment of clamping, transfer, and labeling.

[0028] In some embodiments, according to Figure 4 as well as Figure 6As shown, the high-speed adaptive positioning clamping and labeling integrated component 500 includes a laser position sensor 504 and two elastic arc-shaped clamps 510. The laser position sensor 504 is used to capture the product position in real time and trigger subsequent clamping and transfer actions. The two elastic arc-shaped clamps 510 are used to automatically fit the product shape and elastically compensate for gaps. An electromagnet 511 is embedded at one end of each of the two elastic arc-shaped clamps 510, and all four electromagnets 511 are used to provide adjustable suction force. A set of micro-adsorption chambers 514 is provided on the inner surface of each of the two elastic arc-shaped clamps 510, and both sets of micro-adsorption chambers 514 are used to enhance the adhesion to irregular surfaces.

[0029] according to Figure 3 As shown, the high-speed adaptive positioning clamping labeling integrated component 500 also includes two slide rails 501. One side of the outer wall of each slide rail 501 is fixedly connected to both sides of the outer wall of the conveying component 200. One end of the outer wall of each slide rail 501 is bolted with a fixing plate 502.

[0030] according to Figure 4 As shown, a connecting plate 503 is bolted between the outer walls of the two fixed plates 502. The connecting plate 503 is bolted to the opposite side of the laser position sensor 504, and the laser position sensor 504 is directly opposite the central axis of the conveying assembly 200.

[0031] according to Figure 4 As shown, sliders 507 are slidably connected between the inner surfaces of the two slide rails 501, and electric cylinders 505 are installed on the other side of the outer walls of the two fixed plates 502.

[0032] according to Figures 3-4 As shown, the shaft ends of the two electric cylinders 505 are fixedly connected to support blocks 506. One side of the outer wall of each support block 506 is bolted to a corresponding slider 507. One side of the outer wall of each slider 507 is bolted to a metal plate 508.

[0033] according to Figures 4-5 As shown, miniature electric actuators 509 are fixedly installed on the opposite side of the two metal plates 508. The shaft end of each miniature electric actuator 509 is fixedly connected to the opposite side of a corresponding elastic arc-shaped clamp 510. A set of guide plates 512 are connected to the inner surface of each elastic arc-shaped clamp 510.

[0034] according to Figures 5-6 As shown, a set of springs 513 are connected between the inner surfaces of each set of guide plates 512. One end of the outer wall of each set of springs 513 is elastically connected to a corresponding set of micro-adsorption chambers 514. The top of each set of micro-adsorption chambers 514 is connected to a negative pressure interface 515. One side of the outer wall of each set of micro-adsorption chambers 514 is connected to a set of silicone adsorption ports 516.

[0035] The overall effect of this embodiment is as follows: The above-mentioned components constitute a complete high-speed adaptive positioning clamping and labeling integrated assembly 500, achieving fully automated control of the entire process of packaging product 400 from high-speed conveying, precise positioning, flexible clamping to stable labeling. This completely solves the core pain points of traditional labeling devices, such as poor adaptability, large labeling deviation, easy material damage, and slow response. When the conveying assembly 200 moves the packaging product 400, the laser position sensor 504 can quickly capture the product position and trigger a signal. The electric cylinder 505 drives the slider 507 to move at high speed along the slide rail 501, causing the elastic arc-shaped clamping plate 510 to simultaneously approach both sides of the product. At this time, the miniature electric push rod 509 precisely pushes the clamping plate. With the cooperation of the guide plate 512 and the spring 513, the elastic arc-shaped clamping plate 510 can follow the shape of the product. Automatic bonding allows for adaptation to various product specifications with different widths and heights without the need to replace the flexible arc-shaped clamp 510. Simultaneously, the electromagnet 511 generates adjustable suction force when energized, and the micro-adsorption chamber 514 is connected to a vacuum pump through the negative pressure interface 515. The silicone adsorption port 516 tightly adheres to the product surface, forming a triple fixation of mechanical clamping, magnetic attraction, and negative pressure adsorption. Combined with the buffering effect of the spring 513, this not only prevents product posture deviation and slippage during high-speed transfer but also eliminates the problems of wrinkles in flexible packaging and dents and scratches in rigid packaging. Furthermore, the entire high-speed adaptive positioning clamping and labeling integrated component 500 adopts modular bolt assembly, and the core components can be disassembled independently, significantly reducing production line downtime losses. It is also compatible with mixed production lines of multiple specifications, thereby effectively improving the flexibility and production economy of the packaging production line.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or equivalent variations to the above-disclosed technical content and apply them to other fields. However, any simple modifications, equivalent variations, and alterations made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
