Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, specifically a high-capacity automated edge-finding labeling device. Background Technology

[0002] In modern industrial production, labeling is an essential step in the packaging process, which requires the use of labeling machines.

[0003] Labeling machines are devices that affix rolls of self-adhesive labels (paper or metal foil) to PCBs, products, or prescribed packaging. By affixing labels to products, they can distinguish product categories and serve as identification. In addition, when the labels are affixed to rolls of material, they can also be used to fix the ends of the strip on the roll to prevent the roll from unraveling.

[0004] Existing labeling machines, such as the Chinese patent with authorization announcement number CN217533584U entitled "A Labeling Mechanism for a Labeling Machine," disclose a labeling mechanism for a labeling machine, including an electric telescopic rod. A connecting plate is connected to one bottom end of the electric telescopic rod, and telescopic rods are symmetrically and vertically connected to the bottom of the connecting plate. A rubber plate is connected to one bottom end of the telescopic rod, and a conveying device is provided under the rubber plate. A product is placed on the conveying device. Connecting frames are vertically and symmetrically arranged on both sides of the electric telescopic rod, and guide rollers are hinged to the bottom of the connecting frames. The bottom of the guide rollers is flush with the bottom of the rubber plate.

[0005] The aforementioned patent describes a labeling mechanism for a labeling machine that uses rollers and rubber plates in combination to better adhere labels to product surfaces, thus improving labeling quality. However, existing technologies, including the aforementioned patent, have limited label capacity, requiring frequent label changes. This not only increases the frequency of manual intervention and reduces production efficiency but may also lead to production interruptions, affecting the continuity of the overall production process. Furthermore, as the number of label sheets increases, the high-speed rotation of the label sheets affects their stability, impacting the overall labeling quality to some extent. Utility Model Content

[0006] The purpose of this invention is to provide a high-capacity automated edge-finding and labeling device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-capacity automated edge-finding labeling device, comprising a frame and a mounting frame slidably connected to the frame. The frame is provided with a conveying mechanism for conveying fabric, and a take-up roller is rotatably connected to the mounting frame, and a motor for driving the take-up roller to rotate is provided on the mounting frame. A carrying roller is also rotatably connected to the mounting frame, and a label is placed on the carrying roller. A positioning mechanism is also provided between the carrying roller and the mounting frame to improve the stability of the carrying roller during installation.

[0008] Furthermore, a fixed frame is fixedly connected to the mounting frame via a positioning rod, and the bearing roller is mounted on the fixed frame via a positioning mechanism.

[0009] Furthermore, the positioning mechanism includes an installation cylinder, the bearing roller is rotatably connected to the installation cylinder, and also includes a threaded rod threadedly connected to the mounting frame. The installation cylinder has a threaded groove inside, and the threaded rod is threadedly connected to the threaded groove.

[0010] Furthermore, bearing portions are provided at both ends of the bearing roller and the mounting cylinder.

[0011] Furthermore, a drive groove is provided at the end of the threaded rod to drive the threaded rod to rotate.

[0012] Furthermore, a take-up frame is fixedly connected to the take-up roller, and the label paper is installed in rolls between the take-up frames.

[0013] Furthermore, the frame is provided with guide rails, the mounting bracket is slidably connected to the frame via the guide rails, and the guide rails are provided with a drive mechanism for driving the mounting bracket to slide.

[0014] Furthermore, the driving mechanism includes a lead screw rotatably connected to a guide rail, a threaded sleeve threadedly connected to the lead screw on a mounting bracket, and a servo motor for driving the lead screw to rotate on the guide rail.

[0015] Furthermore, the mounting bracket is equipped with a follow-up photoelectric sensor via screws.

[0016] Furthermore, a label peeling plate is also installed on the mounting frame, through which the label paper passes, and a label pressing roller is also provided on the mounting frame to press the label body that has been attached to the fabric.

[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: This high-capacity automated edge-finding labeling device, through the cooperation of the mounting frame, take-up roller, carrier roller, and positioning mechanism, achieves rigid locking and precise positioning of the carrier roller by installing it at a specific position on the mounting frame. This improves the stability of the carrier roller during installation, ensuring no shaking during high-speed operation, preventing label offset, and guaranteeing labeling accuracy. Furthermore, by employing a large-capacity carrier roller and a matching take-up frame structure, the device can accommodate significantly larger label rolls while maintaining the stability of the carrier roller. This directly reduces the frequency of label replacement, avoiding production interruptions caused by frequent downtime for material changes. The equipment can maintain high-speed labeling during long-term continuous operation, significantly improving the equipment's production efficiency. Attached Figure Description

[0032] 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.

[0033] Please see Figures 1-12 This utility model provides a technical solution: a high-capacity automated edge-finding labeling device, including a frame and a mounting frame 1 slidably connected to the frame. The frame is provided with a conveying mechanism for conveying fabric 13. A take-up roller 4 is rotatably connected to the mounting frame 1, and a motor 11 for driving the take-up roller 4 to rotate is provided on the mounting frame 1. A carrying roller 9 is also rotatably connected to the mounting frame 1, and a label paper 15 is provided on the carrying roller 9. A positioning mechanism 17 is also provided between the carrying roller 9 and the mounting frame 1 to improve the stability of the carrying roller 9 during installation.

[0034] Specifically, this high-capacity automated edge-finding labeling device includes a frame and a mounting frame 1 slidably connected to the frame. The mounting frame 1 slides on the frame, allowing its state to be adjusted according to different work periods, reducing time wasted on position adjustments during labeling and thus improving labeling efficiency. The frame is equipped with a conveying mechanism for transporting the fabric 13; this conveying mechanism is existing technology, and its structure and working principle will not be described in detail here. A take-up roller 4 is rotatably connected to the mounting frame 1, and a motor 11 is installed on the mounting frame 1 to drive the take-up roller 4. Specifically, the motor 11 is connected to the take-up roller 4 via a reducer to meet the needs of waste paper take-up. A carrier roller 9 is also rotatably connected to the mounting frame 1, and label paper 15 is mounted on the carrier roller 9. A positioning mechanism 17 is also provided between the carrier roller 9 and the mounting frame 1 to improve the stability of the carrier roller 9 during installation. Specifically, the labeled waste paper is wrapped around the take-up roller 4. When the motor 11 starts, it can drive the take-up roller 4 to rotate and continuously feed the waste paper as it is being taken up.

[0035] The specific positioning mechanism 17 mounts the carrier roller 9 to a specific position on the mounting frame 1, achieving rigid locking and precise positioning of the carrier roller 9, thereby improving the stability of the carrier roller 9 during installation. Simultaneously, while ensuring the stability of the carrier roller 9, the positioning mechanism 17 utilizes a large-capacity carrier roller 9 and a matching winding frame 10 structure to accommodate significantly larger rolls of label paper 15, ensuring that the carrier roller 9 operates without wobbling at high speeds, preventing label misalignment, and guaranteeing labeling accuracy. This directly reduces the frequency of changing label paper 15, avoiding production interruptions caused by frequent shutdowns for material changes. The equipment can maintain high-speed labeling during long-term continuous operation, significantly improving the equipment's production efficiency.

[0036] In the embodiments provided by this utility model, a fixed frame 16 is fixedly connected to the mounting frame 1 by a positioning rod, and the bearing roller 9 is mounted on the fixed frame 16 by a positioning mechanism 17. The fixed frame 16 is an independent component, which simplifies the disassembly and assembly process of the bearing roller 9 and facilitates maintenance.

[0037] In the embodiments provided by this utility model, the positioning mechanism 17 includes an mounting cylinder 172, with the bearing roller 9 rotatably connected to the mounting cylinder 172. It also includes a threaded rod 171 threadedly connected to the mounting frame 1. A threaded groove 173 is provided inside the mounting cylinder 172, and the threaded rod 171 is threadedly connected to the threaded groove 173. When it is necessary to connect the bearing roller 9 to the fixing frame 16, the threaded rod 171 is driven to rotate, connecting the threaded rod 171 to the threaded groove 173 inside the mounting cylinder 172, so that the threaded rod 171 is inserted into the mounting cylinder 172, limiting the bearing roller 9. The self-locking characteristic of the threaded rod prevents the bearing roller 9 from shifting due to equipment vibration, improving long-term stability. More specifically, the rotation of the threaded rod 171 is used to fix and disassemble the bearing roller 9, improving the stability of the bearing roller 9 during installation and disassembly, and meeting operational requirements.

[0038] Preferably, in order to further improve the stability of the bearing roller 9 during installation with the fixed frame 16, an additional nut is added to the fixed frame 16. During the stroke of the threaded rod 171 to fix the mounting cylinder 172, the nut will also lock the threaded rod 171 a second time, further improving the stability of the bearing roller 9 during installation.

[0039] In the embodiments provided by this utility model, bearing portions 174 are provided at both ends of the bearing roller 9 and the mounting cylinder 172, and friction damping plates are also provided between the bearing roller 9 and the mounting frame 1 to avoid inertial vibration when the label paper 15 starts and stops, and to ensure a smooth labeling process.

[0040] In the embodiments provided by this utility model, a drive groove 175 is provided at the end of the threaded rod 171 for driving the threaded rod 171 to rotate. The threaded rod 171 can be quickly tightened / loosened by tools, which greatly shortens the replacement time of the bearing roller 9.

[0041] In the embodiment provided by this utility model, a take-up frame 10 is fixedly connected to the take-up roller 4, and the label paper 15 is installed in a roll between the take-up frames 10. Specifically, the take-up frames 10 restrict the lateral displacement of the label paper 15 to prevent tangling and disorder.

[0042] In the embodiment provided by this utility model, a guide rail 2 is provided on the frame, and the mounting frame 1 is slidably connected to the frame via the guide rail 2. A drive mechanism 3 for driving the mounting frame 1 to slide is provided on the guide rail 2. The drive mechanism 3 includes a lead screw rotatably connected to the guide rail 2, a threaded sleeve threadedly connected to the lead screw on the mounting frame 1, and a servo motor 11 for driving the lead screw to rotate on the guide rail 2. Because the mounting frame 1 can move laterally, it works in conjunction with the edge-tracking photoelectric sensor 12 to track the edge of the fabric 13 in real time, preventing the fabric 13 from deviating (such as textile rolls) and ensuring that the label is always attached to the set position.

[0043] In the embodiment provided by this utility model, an edge-following photoelectric sensor 12 is installed on the mounting frame 1 by screws. The edge-following photoelectric sensor 12 detects the edge position of the fabric 13 in real time, feeds back the signal to the control system, and dynamically adjusts the posture of the mounting frame 1 to achieve fully automatic edge-following labeling. Specifically, the edge-following photoelectric sensor 12 is a prior art technology; it is a high-precision, high-response photoelectric sensor that detects and reports the precise position of the packaging edge in real time. The control system uses this signal to dynamically drive the labeling head to move laterally, so that it always follows the actual edge position of the packaging, thereby ensuring that even if the packaging deviates on the conveyor belt on a high-speed production line, the label can be accurately and stably affixed to the designated position on the outside. The edge-following photoelectric sensor 12 is a key component for ensuring the accuracy and consistency of high-speed labeling.

[0044] In the embodiments provided by this utility model, a peeling plate 8 is also installed on the fixing frame 16, and the label paper 15 passes through the peeling plate 8. The label material (usually in roll form) consists of a backing paper (release paper) and a face material (the label itself). The backing paper is coated with a silicone oil layer, making the label relatively easy to peel off. Because the label itself has a certain stiffness (relatively hard), while the backing paper is relatively soft and has a release layer, when the label tape makes a sharp turn at the peeling blade, the label will try to maintain a straight movement due to its stiffness, thus separating from the backing paper. The backing paper then continues to move backward along the curved or flat surface of the peeling plate 8. Furthermore, a pressure roller 6 is also provided on the mounting frame 1 to press the label body 14 already attached to the fabric 13. The pressure roller 6 performs secondary compaction to eliminate air bubbles / curling edges.

[0045] In another embodiment of this utility model, a label dragging plate 5 is provided on the mounting frame 1, a bearing plate 18 is installed on the label dragging plate 5, and the label pressing roller 6 is set on the bearing plate 18 through an adjustment mechanism 19. The adjustment mechanism 19 includes a mounting plate 191, and the label pressing roller 6 is rotatably connected to the mounting plate 191 through a shaft; it also includes an adjustment bolt 192 rotatably connected to the mounting plate 191, and an internal thread 193 is provided on the bearing plate 18, and the adjustment bolt 192 is threadedly connected to the internal thread 193.

[0046] The label roller 6 is positioned on the support plate 18 via the adjustment mechanism 19, allowing its position to be flexibly adjusted according to actual labeling needs. This includes adjusting the pressure between the label roller 6 and the fabric 13, or adjusting the horizontal position of the label roller 6. This better adapts to fabrics 13 of different thicknesses and materials, as well as label bodies 14 of different sizes, further improving labeling quality and equipment applicability. Specifically, the adjustment is achieved by rotating the adjusting bolt 192, making operation convenient and requiring no complex tools or equipment. This reduces maintenance and operational difficulty, improving equipment usability.

[0047] In the embodiments provided by this utility model, a driving block 194 is also fixedly connected to the adjusting bolt 192 for driving the adjusting bolt 192 to rotate. During use, the operator can manually rotate the driving block 194 to adjust the position of the label roller 6 without directly contacting the adjusting bolt 192, thus improving the convenience and safety of operation. A limiting member 20 is also provided between the mounting plate 191 and the bearing plate 18 to further limit the state of the label roller 6 and meet operational needs.

[0048] In the embodiments provided by this utility model, the limiting member 20 includes a limiting rod 201 fixedly connected to the mounting plate 191. The limiting rod 201 is slidably connected to the bearing plate 18 through a limiting groove 204, and a retaining ring 202 is provided inside the limiting rod 201. A buffer spring 203 is provided between the retaining ring 202 and the limiting groove 204. When the pressure on the label roller 6 is removed, the buffer spring 203 can automatically return to its initial state, driving the label roller 6 back to its normal working position.

[0049] In another embodiment of this utility model, a guide roller 7 is also provided between the peeling plate 8 and the winding roller 4. The guide roller 7 can guide and adjust the conveying path of the label paper 15 between the peeling plate 8 and the winding roller 4, ensuring that the label paper 15 always maintains the correct direction and tension during the conveying process, avoiding problems such as deviation, twisting or jamming of the label paper 15 during the conveying process, thereby ensuring the smooth conveying and peeling of the label paper 15 and improving the labeling efficiency and quality.

[0050] It should be noted that the electrical equipment involved in this application can be powered by a storage battery or an external power source. In addition, this application is equipped with a control system for controlling the operation of the entire equipment. This control system is prior art and will not be described in detail here.

[0051] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" 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.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
