Description

Technical Field

[0001] This utility model relates to the technical field of automated equipment, and in particular to a fully automatic labeling device. Background Technology

[0002] A labeling device is an automated device used to automatically affix or print identification codes on products, packaging, or goods. Through mechanical structures or electronic control systems, it accurately attaches pre-set labels or codes to the surface of the target object. It is commonly used in production lines, logistics sorting, and warehouse management to improve labeling efficiency, reduce human error, and achieve information traceability. The core functions of a labeling device include positioning, coding, and verification. It can integrate multiple technologies such as inkjet printing, laser engraving, or affixing pre-made labels as needed, making it an important tool for modern industrial intelligent and data-driven management.

[0003] A search revealed an existing patent (publication number: CN220054496U) that discloses a fully automatic labeling device. This utility model, through the setting of a corresponding mechanism, can press the labels on the fish glue firmly, so that the labels adhere firmly to the fish glue, thereby reducing the probability of the labels detaching from the fish glue, ensuring the adhesion quality of the labels, and also reducing the probability of re-labeling.

[0004] However, in the above solution, if the objects on the conveyor belt shift position during the conveying process, it will directly affect the stability and accuracy of the labeling system. Since the objects may undergo lateral displacement during movement, the labeling machine's sensors may not be able to accurately identify the actual position of the objects, resulting in the labeling position deviating from the preset area, affecting the readability and aesthetics of the labels. At the same time, the position shift may cause the photoelectric sensor to misjudge the existence of the objects, leading to the problem of missing labels or repeated labeling of the same objects. This not only reduces production efficiency but also leads to data acquisition errors in subsequent processes. Utility Model Content

[0005] In view of the problem that existing objects may experience lateral displacement during movement, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a fully automatic labeling device, which aims to center the object on the transmission mechanism through the centering component, so that the electric push rod drives the labeling device body to label the object, ensuring that the object is always in the preset center or standard position.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a fully automatic labeling device, including a housing, a box body fixed to one end of the side of the housing, a servo motor inside the box body, support columns fixed to the four corners of the bottom of the housing, an outer shell fixed to the center of the bottom of the housing, a height adjustment component provided on the inner bottom wall of the housing, a transmission mechanism installed on the inner side of the housing, a centering component above the transmission mechanism, a top plate movably connected to the top of the housing, an electric push rod installed at the center of the top of the top plate, and the output end of the electric push rod penetrating the top plate and fixed to the labeling device body; The output end of the servo motor drives the transmission mechanism through a coupling that passes through one side of the housing. The transmission direction of the transmission mechanism is from left to right.

[0008] In a preferred embodiment of the fully automatic labeling device of this utility model, the centering component includes two limiting blocks, which are disposed opposite to each other on the inner side of the housing. Three I-shaped rods are provided at equal intervals on the side of the limiting blocks near the inner wall of the housing. One end of each I-shaped rod extends to the inner side of the limiting block, and the other end of each I-shaped rod is fixedly connected to the inner wall of the housing. A connecting spring is sleeved on the middle section surface of the I-shaped rod and fixedly connected to one side of the limiting block.

[0009] In a preferred embodiment of the fully automatic labeling device of this utility model, the two limiting blocks are provided with inclined grooves at the ends of the two blocks that are close to the conveying direction of the transmission mechanism, the two inclined grooves are arranged opposite each other, and the inclination angle of the inclined grooves is 45°~60°.

[0010] As a preferred embodiment of the fully automatic labeling device of this utility model, a circular groove is provided on the inner side of the limiting block and at the corresponding position of one end of the three I-shaped rods. The side of one end of the I-shaped rod extending to the inner side of the limiting block is in contact with the inner wall of the circular groove, and the I-shaped rod is slidably connected to the inner side of the circular groove.

[0011] In a preferred embodiment of the fully automatic labeling device of this utility model, the height adjustment component includes a drive motor, which is fixed inside the housing. The output end of the drive motor passes through the bottom end of the housing and is fixed to a first transmission wheel via a coupling. Two first transmission chains are equidistantly and staggeredly distributed on the surface of the first transmission wheel and rotatably connected to it. A second transmission wheel is sleeved on the inner side of one end of the first transmission chain. A second transmission chain is rotatably connected to the surface of the second transmission wheel. A third transmission wheel is sleeved on the inner side of one end of the second transmission chain. Threaded rods are fixed to the top ends of the second and third transmission wheels. Columns are threadedly connected to the surface of the threaded rods. The top ends of the four columns are fixedly connected to the bottom end of the top plate.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model uses a centering component to center objects on the transmission mechanism, enabling the electric push rod to drive the labeling device to label the objects. This ensures that the objects are always in a preset center or standard position, eliminating the offset errors common in manual placement or traditional transmission. The labeling device can strictly follow the planned path to perform the labeling action, significantly reducing problems such as labeling misalignment and skewing. At the same time, the centering positioning keeps the labeling position away from the edge of the object, further reducing the probability of the label being scratched or falling off during subsequent handling and extending the label's service life.

[0015] 2. This utility model adjusts the height of the top plate using a height adjustment component, thereby adjusting the working height of the electric push rod and the labeling device body. This allows for quick adjustment of the labeling height to accommodate packaging boxes or products of different thicknesses and sizes without the need to replace hardware, significantly improving the equipment's versatility. When switching product types on the production line, the programmed height adjustment enables a seamless transition, reducing downtime. Simultaneously, it automatically detects product height and provides feedback for adjustment, reducing manual intervention. Dynamic height adjustment ensures a stable labeling rhythm and avoids mechanical collisions or missed labels. Attached Figure Description

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Example 1 Reference Figures 1-3 This is the first embodiment of the present invention, providing a fully automatic labeling device. The device includes a housing 1, with a box 2 fixed to one side of the housing 1. A servo motor 3 is housed inside the box 2. The box provides physical protection for the servo motor, effectively isolating it from external dust, foreign objects, or accidental collisions, ensuring stable operation of the servo motor under complex working conditions, extending its service life, and preventing the motor from being exposed and affecting the overall aesthetics of the device. Support columns 4 are fixed at the four corners of the bottom of the housing 1, forming a stable support structure that significantly reduces shaking caused by vibration or load during operation, improving the overall structural rigidity and providing a foundation for the accuracy of subsequent transmission and labeling operations. An outer shell 5 is fixed at the center of the bottom of the housing 1. The inner bottom wall of the housing 1... The device is equipped with a height adjustment component 6, a transmission mechanism 7 is installed inside the housing 1, and a centering component 8 is installed above the transmission mechanism 7. The transmission mechanism realizes the automated continuous conveying of objects to be labeled, replacing manual feeding and greatly improving production efficiency. The clear unidirectional transmission direction facilitates the synchronous control of the centering component 8 and the labeler body 10, ensuring the continuity and rhythm of the labeling process. A top plate 11 is movably connected to the top of the housing 1, and an electric push rod 9 is installed at the center of the top of the top of the top plate 11. The output end of the electric push rod 9 passes through the top plate 11 and is fixed to the labeler body 10. The height of the top plate 11 and the labeler body 10 can be dynamically adjusted by the height adjustment component to adapt to objects of different thicknesses, expand the applicability of the device, and avoid the redundant cost of designing separate equipment for objects of different thicknesses. The output end of the servo motor 3 drives the transmission mechanism 7 through a coupling through one side of the housing 1. The transmission direction of the transmission mechanism 7 is from left to right.

[0020] The centering component 8 includes two limiting blocks 801, which are disposed opposite each other on the inner side of the housing 1. Three I-shaped rods 802 are provided at equal intervals on the side of the limiting block 801 near the inner wall of the housing 1. One end of the I-shaped rod 802 extends into the inner side of the limiting block 801, and the other end of the I-shaped rod 802 is fixedly connected to the inner wall of the housing 1. A connecting spring 803 is sleeved on the middle section surface of the I-shaped rod 802 and fixedly connected to one side of the limiting block 801. Through the cooperation of the I-shaped rod and the connecting spring, the two limiting blocks can adapt to objects of different widths to be labeled under the action of the spring elastic force, pushing them to the center of the transmission mechanism, thus solving the problem that traditional rigid limiting is prone to damaging objects or cannot be compatible with multiple sizes.

[0021] Two limit blocks 801 are provided with inclined grooves 8012 at the end near the conveying direction of the transmission mechanism 7. The two inclined grooves 8012 are arranged opposite each other, and the inclination angle of the inclined grooves 8012 is 45°~60°. The 45°~60° inclined groove design at the front end of the limit block allows the limit block to gradually move to both sides when the object enters, reducing the initial contact resistance, avoiding the object from getting stuck or scratching the surface, and improving the smoothness of feeding.

[0022] A circular groove 8011 is provided on the inner side of the limiting block 801 at the corresponding position of one end of the three I-shaped rods 802. The side of the I-shaped rod 802 extending to the inner side of the limiting block 801 fits against the inner wall of the circular groove 8011. The I-shaped rod 802 is slidably connected to the inner side of the circular groove 8011. The sliding cooperation between the I-shaped rod and the circular groove restricts the radial offset of the limiting block, ensuring that its movement trajectory under the action of the spring is a straight line. Combined with two symmetrically arranged limiting blocks, the centering accuracy of the object can be controlled within a small error range, significantly improving the consistency of the labeling position.

[0023] Example 2 Reference Figures 1-5This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the height adjustment component 6 includes a drive motor 601, which is fixed inside the housing 5. The output end of the drive motor 601 passes through the bottom end of the housing 1 and is fixed to a first transmission wheel 602 via a coupling. Two first transmission chains 603 are equidistantly and staggeredly distributed on the surface of the first transmission wheel 602 and rotatably connected to it. A second transmission wheel 604 is sleeved on the inner side of one end of each first transmission chain 603. A second transmission chain 605 is rotatably connected to the surface of the second transmission wheel 604. A third transmission wheel 606 is sleeved on the inner side of one end. A threaded rod 607 is fixed to the top of the second transmission wheel 604 and the third transmission wheel 606. A column 608 is threadedly connected to the surface of the threaded rod 607. The threaded transmission converts the rotational motion into linear motion, and the structure is simple and reliable. The top plate can be raised or lowered by controlling the rotation direction of the drive motor, which is convenient to operate. The self-locking characteristic of the thread, such as the use of a trapezoidal thread, can lock the position of the column when the motor stops, preventing the top plate from sliding down due to gravity or vibration, and improving the stability of height adjustment. The tops of the four columns 608 are fixedly connected to the bottom of the top plate 11.

[0024] A groove 101 is provided on the inner wall of the housing 1 at the position corresponding to the column 608. The shape of the column 608 is the same as the inner shape of the groove 101. The column 608 slides vertically on the inner side of the groove 101.

[0025] The first drive wheel 602, the second drive wheel 604, and the third drive wheel 606 are always on the same horizontal line. The diameter of the first drive wheel 602 is twice the diameter of the second drive wheel 604, and the diameter of the second drive wheel 604 is the same as the diameter of the third drive wheel 606. The first drive wheel, the second drive wheel, and the third drive wheel are always on the same horizontal line, and the diameter of the first drive wheel is twice that of the second drive wheel. The two-stage transmission achieves reasonable control of the lifting speed of the top plate, while ensuring that the threaded rods 607 on both sides rotate synchronously, avoiding the top plate from tilting due to uneven force on one side.

[0026] The remaining structure is the same as that in Example 1.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
