[0030] 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.

[0031] Please see Figures 1-10 This utility model provides a technical solution: an automatic edge-finding labeling machine for outer label replacement, 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 and a guide rail 2. The mounting frame 1 is slidably connected to the frame through the guide rail 2, and a driving mechanism 3 for driving the mounting frame 1 to slide is provided on the guide rail 2. A take-up roller 4 and a carrier roller 9 are rotatably connected to the mounting frame 1. A label paper 15 is provided on the carrier roller 9, and a label peeling component is also provided between the take-up roller 4 and the carrier roller 9. The label paper 15 passes through the label peeling component and is wound around the take-up roller 4. A motor 11 for driving the take-up roller 4 to rotate is provided on the mounting frame 1.

[0032] Specifically, the automatic edge-finding labeling machine for external labeling includes a frame and a mounting frame 1 slidably connected to the frame. The frame is equipped with a conveying mechanism for conveying fabric 13 and a guide rail 2. The mounting frame 1 is slidably connected to the frame via the guide rail 2, and a driving mechanism 3 is provided on the guide rail 2 to drive the mounting frame 1 to slide. The mounting frame 1 can slide along the guide rail 2, allowing the labeling machine to quickly and accurately move to the designated position on the fabric 13 for labeling, reducing the time wasted due to position adjustments during the labeling process and thus improving labeling efficiency. A take-up roller 4 and a carrier roller 9 are rotatably connected to the mounting frame 1. Label paper 15 is placed on the carrier roller 9, and a label peeling component is also provided between the take-up roller 4 and the carrier roller 9 on the mounting frame 1. The coordinated use of the take-up roller 4, the carrier roller 9, and the label peeling component enables automatic conveying and peeling of the label paper 15, further improving the automation level of the labeling process, reducing manual intervention, and ensuring the stability and consistency of labeling. After the label paper 15 passes through the label peeling assembly, it is wound onto the take-up roller 4, and the mounting frame 1 is equipped with a motor 11 for driving the take-up roller 4 to rotate. Specifically, the motor 11 is connected to the take-up roller 4 through a reducer to meet the needs of waste paper winding. The labeled waste paper is wound onto the take-up roller 4, and when the motor 11 starts, it can drive the take-up roller 4 to rotate during the winding of the waste paper for continuous feeding. Specifically, the mounting frame 1 is slidably connected to the machine frame through a guide rail 2, and the guide rail 2 is equipped with a drive mechanism 3 for driving the mounting frame 1 to slide. The drive mechanism 3 drives the mounting frame 1 to slide on the machine frame, realizing the external label changing function. The label paper 15 can be changed without removing the labeling machine from the material area, greatly improving the convenience and efficiency of label changing, reducing downtime due to label changing, and improving production efficiency.

[0033] In the embodiments provided by this utility model, the label peeling assembly includes a peeling plate 8 mounted on a mounting frame 1, through which the label paper 15 passes. A pressure roller 6 is also provided on the mounting frame 1 to press the label body 14 already affixed to the fabric 13. The label material (usually in roll form) consists of a backing paper (e.g., release paper) and a face stock (label body). 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, while the backing paper is relatively soft and has a release layer, when the label tape makes a sharp turn at the peeling edge, the label will attempt to maintain a straight line 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. The pressure roller 6 on the mounting frame 1 further presses the label body 14 already affixed to the fabric 13, eliminating air bubbles / curling edges.

[0034] In the embodiment provided by this utility model, a label-dragging plate 5 is provided on the mounting frame 1, and a support plate 18 is installed on the label-dragging plate 5. The label-pressing roller 6 is set on the support 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. The support plate 18 has an internal thread 193, and the adjustment bolt 192 is threadedly connected to the internal thread 193. By setting the label-pressing roller 6 on the support plate 18 through the adjustment mechanism 19, the position of the label-pressing roller 6 can be flexibly adjusted according to the actual labeling requirements, such as adjusting the pressure between the label-pressing roller 6 and the fabric 13 or the horizontal position of the label-pressing roller 6, thereby better adapting to fabrics 13 of different thicknesses and materials and label bodies 14 of different sizes, further improving the labeling quality and the applicability of the equipment. Specifically, by rotating the adjustment bolt 192, the operation is convenient, and the position of the label-pressing roller 6 can be adjusted without complicated tools or equipment, reducing the maintenance and operation difficulty of the equipment and improving the ease of use of the equipment.

[0035] 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.

[0036] 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.

[0037] 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 existing 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. Moreover, the edge-following photoelectric sensor 12 is a key component to ensure the accuracy and consistency of high-speed labeling.

[0038] 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.

[0039] In the embodiments provided by this utility model, the driving 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. During use, the driving mechanism 3 controls the mounting frame 1 to slide on the frame, and the edge tracking photoelectric eye 12 tracks the edge of the fabric 13 in real time to prevent the fabric 13 from deviating and ensure that the label is always attached to the set position.

[0040] In the embodiments provided by 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.

[0041] In another embodiment 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.

[0042] In the embodiments provided by this utility model, the positioning mechanism 17 includes an installation cylinder 172, a bearing roller 9 rotatably connected to the installation cylinder 172, and a threaded rod 171 threadedly connected to the mounting frame 1. A threaded groove 173 is provided inside the installation 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 installation cylinder 172, so that the threaded rod 171 is inserted into the installation 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, meeting operational requirements. A drive groove 175 is provided at the end of the threaded rod 171 for driving the threaded rod 171 to rotate.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.
