Description

Technical Field

[0001] This utility model relates to the technical field of labeling devices for rewinding machines, and in particular to a swing arm type labeling device for rewinding machines. Background Technology

[0002] Rewinding machines, as specialized equipment for processing materials such as paper, mica tape, and film, play a crucial role in industrial production. Their main function is to rewind large rolls of material sequentially according to specific requirements, precisely separating them into smaller rolls that meet actual needs. This process greatly improves the convenience of subsequent material handling and facilitates its use in various scenarios, enabling materials to better adapt to different production stages and processes.

[0003] After the rewinding machine completes the slitting operation, these small rolls of material usually need to be labeled to facilitate management, identification, and traceability. In traditional production models, labeling machines are often directly installed and connected to the rewinding machine. While this installation method achieves the basic labeling function, allowing labels to be smoothly applied to the small rolls, it has several drawbacks. Firstly, the labeling machine obstructs the rewinding machine to some extent. This interferes with operators' observation of the rewinding machine's operation, making it difficult to clearly and comprehensively understand the material's condition, rewinding speed, and any abnormalities during the rewinding process. Secondly, this obstruction also greatly inconveniences operators in performing routine maintenance and operation of the rewinding machine. For example, when cleaning, adjusting, or replacing parts, the labeling machine's location may restrict the operator's movement space, increasing the difficulty and time cost of operation.

[0004] The technical content disclosed in Chinese patent document (publication number: CN209275053U, patent name: a labeling device for a rewinding machine) is as follows: The labeling device for a rewinding machine includes a rewinding machine body, a frame, and a labeling device. A through groove is provided through one side wall of the frame for label entry and exit. Rollers for label winding are provided on the outer side wall of the frame near the through groove. A master roll roller is located on the rewinding machine body near the through groove. A support roller is provided on one side of the master roll roller, parallel to its axial direction. A slave roll roller is located above the support roller. A labeling device for labeling the master roll of adhesive tape, located on the frame, is provided between the support roller and the slave roll roller. This designed labeling device allows for labeling of the adhesive tape to be labeled during the rewinding process, saving time, reducing labor costs, and improving productivity.

[0005] As can be seen from the aforementioned patent documents, the labeling device for the rewinding machine also has certain limitations. While the device, located at the front end of the rewinding machine, achieves its intended labeling function, its installation and removal are quite difficult in actual use. This means that during routine operation, maintenance, and repair of the rewinding machine, the device remains positioned between the operator and the machine, creating a significant obstacle. This not only affects the operator's normal use of the rewinding machine but also increases the complexity and difficulty of maintenance, leading to longer repair times, higher costs, and hindering efficient operation and timely maintenance. Therefore, in practical applications, further improvements and optimizations to the device are needed to enhance its ease of use and flexibility. Utility Model Content

[0006] This utility model overcomes the shortcomings of the prior art and provides a swing arm labeling device for a rewinder. The swing arm structure enables the labeling machine to move flexibly in front of the rewinder, meeting the requirements of efficient, intelligent and convenient operation. One end of the labeling machine is hinged to the swing arm sleeve seat on the rewinder via the swing arm pivot, and can rotate around the pivot. When labeling, the labeling machine moves to the front of the rewinder, and when not labeling, it completely exits the working area to avoid obstruction and facilitate maintenance.

[0007] To solve the above-mentioned technical problems, the utility model is implemented through the following technical solution: A swing arm type labeling device for a rewinder includes a labeling machine located in front of the rewinder. The position of the labeling machine is adjusted by a swing arm. One end of the swing arm is rotatably connected to a swing arm sleeve seat via a swing arm pivot. The swing arm sleeve seat is fixed on the rewinder. When labeling is required, the labeler is positioned directly in front of the rewinder by moving the swing arm. When labeling is not required, push the swing arm to rotate around the swing arm pivot, moving the labeler away from the rewinder.

[0008] Furthermore, a swing arm positioning rod is provided at the end of the swing arm away from the swing arm sleeve seat; The rewinder is connected to the swing arm locking seat. After the labeling machine is moved to the front of the rewinder, the swing arm locking seat clamps and locks the swing arm positioning rod, thereby fixing the position of the swing arm.

[0009] Furthermore, the swing arm locking seat is provided with a locking block inner groove, and a locking power component is provided on the side of the swing arm locking seat. The locking power component is connected to the locking movable block, and the locking movable block is provided with a movable block inner groove. After the labeling machine moves to the front of the rewinding machine, the inner groove of the locking block fits against one side of the swing arm positioning rod. Then, the locking power unit pushes out the locking movable block, so that the inner groove of the movable block fits against the other side of the swing arm positioning rod.

[0010] Furthermore, the shapes of the inner groove of the locking block and the inner groove of the movable block are matched with the outer circumferential shape of the swing arm positioning rod.

[0011] Furthermore, the inner groove of the locking block is semi-circular; the inner groove of the movable block is quarter-circular.

[0012] Furthermore, the locking power component is a cylinder or an electric cylinder.

[0013] Furthermore, the labeling machine is also equipped with a label pressing component, and a label output point is provided above the label pressing component; The label pressing component includes an auxiliary base, and a linear bearing is provided inside the auxiliary base. A sliding rod is movably inserted into the linear bearing. The end of the sliding rod is connected to a roller seat, and the roller seat is rotatably connected to the roller.

[0014] Furthermore, a spring is provided between the roller seat and the auxiliary base.

[0015] Furthermore, the labeling machine is connected to the labeling machine moving component; The labeling machine moving component includes a power base, which is connected to a slide rail and a moving power component; The slide rail is connected to the slider, and the labeling machine is connected above the slider. The output end of the mobile power component is connected to the labeling machine via a connector.

[0016] Furthermore, the moving power component is a cylinder or an electric cylinder.

[0017] Compared with existing technologies, the advantages of this utility model are: 1. The labeling machine can move flexibly in front of the rewinding machine through the swing arm structure. One end of the labeling machine is hinged to the swing arm sleeve seat on the rewinding machine via the swing arm pivot, and can rotate around the pivot. When labeling, it can move to the front of the rewinding machine, and when not labeling, it can completely exit the working area to avoid obstruction and facilitate maintenance.

[0018] 2. To ensure accurate positioning, the device is equipped with a swing arm locking seat. The inner groove of the locking block and the inner groove of the movable block respectively fit into the two sides of the positioning rod at the end of the swing arm. With the help of a cylinder or electric cylinder, automatic clamping is achieved, forming a stable and reliable double clamping. This design not only improves the labeling accuracy and stability, but also enhances the operational flexibility and automation level of the equipment. Attached Figure Description

[0021] The preferred embodiments of the utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model.

[0022] like Figures 1 to 6 As shown, a swing arm labeling device for a rewinder includes a labeling machine 4, which is located in front of the rewinder 1. The position of the labeling machine 4 is adjusted by a swing arm 2. One end of the swing arm 2 is rotatably connected to the swing arm sleeve seat 202 via a swing arm pivot 201. The swing arm sleeve seat 202 is fixed on the rewinder 1. The rewinder 1 is connected to a swing arm locking seat 5. After the labeling machine 4 is moved to the front of the rewinder 1, the swing arm locking seat 5 clamps and locks the swing arm positioning rod 203, thereby fixing the position of the swing arm 2.

[0023] When labeling is required, the swing arm 2 is moved to position the labeler 4 directly in front of the rewinder 1; when labeling is not required, the swing arm 2 is pushed to rotate around the swing arm pivot 201, moving the labeler 4 away from the rewinder 1. Unlike the traditional method of directly mounting the labeler 4 onto the rewinder 1, this setup allows for quick switching between labeling and non-labeling states. When not labeling, the labeler 4 is completely moved out of front of the rewinder 1 for easy maintenance. A swing arm locking seat 5 is used to lock the swing arm 2, ensuring accurate labeling positioning and high-quality labeling.

[0024] A swing arm positioning rod 203 is provided at the end of the swing arm 2 away from the swing arm sleeve seat 202; a locking block inner groove 501 is provided on the swing arm locking seat 5, and a locking power component 502 is provided on the side of the swing arm locking seat 5. The locking power component 502 is a cylinder or an electric cylinder. The locking power component 502 is connected to the locking movable block 503, and the locking movable block 503 is provided with a movable block inner groove 5031; when the labeling machine 4 moves to the front of the rewinding machine 1, the locking block inner groove 501 fits against one side of the swing arm positioning rod 203, and then the locking power component 502 pushes out the locking movable block 503, so that the movable block inner groove 5031 fits against the other side of the swing arm positioning rod 203. The shapes of the locking block inner groove 501 and the movable block inner groove 5031 match the outer circumference shape of the swing arm positioning rod 203. The locking block inner groove 501 is semi-circular; the movable block inner groove 5031 is quarter-circular. Through the ingenious cooperation between the swing arm positioning rod 203 and the swing arm locking seat 5 clamping structure, the labeling machine 4 achieves high-precision positioning and stable clamping at the labeling position.

[0025] The inner groove 501 of the locking block adopts a semi-circular arc design, and the inner groove 5031 of the movable block adopts a quarter-circular arc design. When the two are combined, they form a three-quarter circular clamping surface, which perfectly matches the outer circumference of the swing arm positioning rod 203. The arc design can improve the fit between the clamping surface and the swing arm positioning rod 203, avoid local stress concentration, and prevent damage to the positioning rod during clamping. The double-sided clamping structure enhances the overall clamping force and improves the labeling stability. Therefore, it ensures that the contact area of ​​the clamping surface is large and the force is uniform, thereby improving the clamping stability.

[0026] The labeling machine 4 is also equipped with a label auxiliary pressing component 401, and a label output point 402 is provided above the label auxiliary pressing component 401. The label auxiliary pressing component 401 includes an auxiliary base 4011, and a linear bearing 4012 is provided inside the auxiliary base 4011. A sliding rod 4013 is movably inserted into the linear bearing 4012. The end of the sliding rod 4013 is connected to a roller seat 4015, and the roller seat 4015 is rotatably connected to a roller 4016. A spring 4014 is provided between the roller base 4015 and the auxiliary base 4011. After the label is output from the label output port 402, as the film roll rotates, the label is pulled between the film roll and the roller 4016. Due to the presence of the spring 4014, the roller 4016 adheres to the surface of the film roll after the labeling machine 4 approaches it. Therefore, when the label enters between the film roll and the roller 4016, the side of the label with adhesive adheres to the film roll. The roller 4016 resists the side of the label without adhesive due to the rebound force of the spring 4014 after compression, thus making the label adhere more firmly to the film roll. In addition, the setting of the spring 4014 also provides a buffer when the labeling machine 4 approaches the film roll, making the contact between the labeling machine 4 and the film roll gentler, so that the labeling machine 4 and the film roll will not be damaged by impact.

[0027] The labeling machine 4 is connected to the labeling machine moving assembly 3. The labeling machine moving assembly 3 includes a power base 3031, which is connected to a slide rail 301 and a moving power component 303. The slide rail 301 is connected to a slider 302, and the labeling machine 4 is connected above the slider 302, ensuring that the labeling machine 4 can move smoothly and linearly back and forth under the guidance of the slide rail 301. This slide rail and slider structure not only has good guiding properties, but also effectively resists external vibration and impact, ensuring high precision of the labeling position during the labeling process.

[0028] The output end of the mobile power unit 303 is connected to the labeling machine 4 via a connecting seat 304. The mobile power unit 303 can be a pneumatic cylinder or an electric cylinder. Pneumatic cylinders have a simple structure and fast response speed, making them suitable for production environments with high labeling speed requirements and a stable air source. Electric cylinders, on the other hand, offer higher control precision and programmability, making them suitable for automated production lines with strict labeling position requirements and need to be linked with the overall line control system. The output end of the mobile power unit 303 is connected to the labeling machine 4 via a connecting seat 304. The design of the connecting seat balances rigidity and flexibility, ensuring stable and non-deviation-free power transmission, while also facilitating disassembly and maintenance.

[0029] The swing-arm labeling device of this utility model enables the labeling machine to move flexibly in front of the rewinding machine through the swing-arm structure, allowing the labeling machine to quickly switch between labeling and non-labeling states, meeting the multiple needs of modern industrial production for high efficiency, intelligence and convenient operation.

[0030] The labeling machine is connected to a swing arm sleeve seat on the rewinder body at one end of its swing arm, and rotates at the other end via a swing arm pivot. This structure allows the labeling machine to be moved to the front of the rewinder when labeling is needed. In non-labeling states, the swing arm can rotate around its axis, completely removing the labeling machine from the rewinder's working area. To ensure the accuracy and stability of the labeling machine's position during labeling, a swing arm locking seat structure is incorporated. This locking seat is mounted on the rewinder body and works in conjunction with a swing arm positioning rod at the end of the swing arm. When the labeling machine moves to the labeling position, the locking seat firmly secures the positioning rod through a clamping structure, thus achieving precise positioning and stable locking of the labeling machine.

[0031] Traditional labeling machines are fixedly installed in front of rewinding machines, which not only affects the operator's observation of the rewinding machine's operating status, but also brings many inconveniences to the daily maintenance of the equipment. However, this utility model, through the design of the swing arm structure, allows the labeling machine to be completely moved out of front of the rewinding machine when not labeling, providing the operator with ample operating space.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the 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. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the utility model should be included within the protection scope of the utility model.
