Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-adhesive label technology, and in particular to a high-precision self-adhesive label paper processing equipment. Background Technology
[0002] Self-adhesive labels, widely used in product packaging, warehousing management, and logistics distribution, are convenient and practical. They are coated with permanent or removable adhesive on the back, allowing for easy adhesion to various surfaces without the need for additional heat, pressure, or water. These labels ensure excellent adhesion and long-term stability, and are waterproof, oil-proof, and scratch-resistant, adapting to diverse environmental conditions. The variety of designs available, such as glossy, matte, and synthetic paper, meets market demands for different specifications and materials.
[0003] However, with the widespread use of self-adhesive label paper, traditional label paper processing technology faces some problems. During inkjet printing, the label paper may not be completely dried, resulting in pattern smudging or smudging, which affects the printing quality. Due to the differences in label paper material and thickness, traditional equipment often cannot guarantee printing accuracy and positional stability, resulting in a high scrap rate. Especially in the production of high-precision labels, label position deviations often occur, affecting the consistency of the final product. Utility Model Content
[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-precision self-adhesive label paper processing equipment, comprising a machine body, guide rollers fixedly connected to the inner side of the machine body, a mounting rod 1 fixedly connected to the inner side of the machine body, a mounting roller disposed outside the mounting rod 1, a mounting rod 2 fixedly connected to the end of the mounting roller away from the mounting rod 1, the mounting rod 2 being disposed inside a placement frame, a limiting plate fixedly connected to the outside of the mounting roller, an inkjet device fixedly connected to the top of the machine body, and a drying assembly disposed to the right side of the inkjet device, the drying assembly being used to dry the printed paper.
[0005] Preferably, the drying assembly includes a mounting plate, which is fixedly connected to the inner side of the machine body. A heating box is fixedly connected to the top of the mounting plate, and a dustproof net is fixedly connected inside the heating box. A fan is provided at the bottom of the dustproof net, and an electric heating wire is provided at the bottom of the fan. External air is drawn in by the fan, filtered by the dustproof net, and then heated by the electric heating wire to form a clean hot airflow, thereby achieving the supply of heat source for drying the printed label paper.
[0006] Preferably, a connecting pipe is fixedly connected to the bottom of the heating box, and an air distribution box is fixedly connected to the outside of the connecting pipe through the mounting plate. The top of the air distribution box is fixedly connected to the bottom of the mounting plate, and a drying hood is fixedly connected to the bottom of each air distribution box. The hot airflow in the heating box is introduced into the air distribution box through the connecting pipe. After being divided by the air distribution box, it is sprayed out synchronously by multiple drying hoods, so as to achieve uniform coverage of the hot airflow and ensure consistent drying effect of the label paper.
[0007] Preferably, a motor is fixedly connected to the outside of the machine body, and a threaded rod is fixedly connected to the output end of the motor. The other end of the threaded rod is rotatably connected to the inside of the machine body. A slider is threadedly connected to the outside of the threaded rod. The motor drives the threaded rod to rotate, and the threaded transmission drives the slider to move along the axial direction of the threaded rod, thereby realizing precise position adjustment of the slider.
[0008] Preferably, both sides of the slider are slidably connected to the outside of the guide rod, and both ends of the guide rod are fixedly connected to the inside of the machine body. The guide rod limits the sliding direction of the slider, preventing the slider from rotating with the threaded rod, thus achieving smoothness and linearity in the slider movement process.
[0009] Preferably, a mounting frame is fixedly connected to the bottom of the slider, and an electric telescopic rod is fixedly connected inside the mounting frame. The electric telescopic rod is fixed by the mounting frame and can extend and retract in the vertical direction, thereby realizing the height adjustment of the correction plate and adapting to different specifications of label paper.
[0010] Preferably, the output end of the electric telescopic rod is fixedly connected to a correction plate. The inner side of the correction plate abuts against the outer side of the mounting roller. The electric telescopic rod pushes the correction plate to abut against the label paper on the mounting roller. The lateral limiting effect of the correction plate is used to correct the position of the offset label paper and avoid processing deviation.
[0011] In summary, this utility model, through the coordinated operation of multiple components in the drying assembly, utilizes a fan and electric heating wire to quickly generate clean hot airflow, and achieves uniform distribution of hot airflow through an air distribution box and drying hood. This not only enables rapid drying of printed label paper, preventing issues such as smudging and fading due to undried patterns, but also adapts to self-adhesive label paper of different thicknesses and materials. While improving processing efficiency, it effectively ensures the clarity and durability of printed patterns.
[0012] Meanwhile, through the coordinated design of the motor, threaded rod, guide rod, electric telescopic rod, and correction plate, the precise movement of the slider can be achieved using threaded transmission and guide limit, and the height of the correction plate can be flexibly adjusted through the electric telescopic rod to adapt to different specifications of label paper. Finally, the lateral limit of the correction plate is used to achieve real-time correction of the offset label paper, which greatly reduces the processing waste caused by position deviation, ensures the positional accuracy of the label paper in inkjet printing and subsequent processing, significantly improves the consistency and pass rate of the product, and meets the processing requirements of high-precision self-adhesive label paper.

[0015] 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. Example
[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides a technical solution: a high-precision self-adhesive label paper processing equipment, including a machine body 1. Guide rollers 3 are fixedly connected to the inner side of the machine body 1. The guide rollers 3 are used to guide the self-adhesive label paper to be stably conveyed along a preset path. An installation rod 21 is fixedly connected to the inner side of the machine body 1. An installation roller 2 is set outside the installation rod 21. The installation roller 2 is used to hold the self-adhesive label paper roll. An installation rod 22 is fixedly connected to the end of the installation roller 2 away from the installation rod 21. The installation rod 22 is set inside the placement frame 20. The installation rod 21 and the installation rod 22 cooperate with the placement frame 20 to form a stable support for the installation roller 2. A limiting plate 23 is fixedly connected to the outside of the installation roller 2. The limiting plate 23 initially limits the two sides of the label paper roll to reduce lateral displacement. An inkjet device 4 is fixedly connected to the top of the machine body 1. The inkjet device 4 is used to print patterns or text on the label paper. A drying component is set on the right side of the inkjet device 4. The drying component is used to dry the printed paper to prevent the undried pattern from being contaminated.
[0017] like Figure 1 , Figure 2 and Figure 4 As shown, the drying assembly includes a mounting plate 12, which is fixedly connected to the inside of the body 1 to provide a mounting base for the drying assembly. A heating box 13 is fixedly connected to the top of the mounting plate 12. A dustproof net 14 is fixedly connected inside the heating box 13. The dustproof net 14 is used to filter impurities in the air entering the heating box 13. A fan 15 is provided at the bottom of the dustproof net 14. The fan 15 is used to draw in external air and send it into the heating box 13. An electric heating wire 16 is provided at the bottom of the fan 15. The electric heating wire 16 is used to heat the air to form a hot airflow.
[0018] like Figure 4 As shown, a connecting pipe 17 is fixedly connected to the bottom of the heating box 13. The connecting pipe 17 is used to exhaust the hot airflow inside the heating box 13. An air distribution box 18 is fixedly connected to the outside of the connecting pipe 17 through the mounting plate 12. The air distribution box 18 is used to evenly distribute the hot airflow. The top of the air distribution box 18 is fixedly connected to the bottom of the mounting plate 12. A drying hood 19 is fixedly connected to the bottom of each air distribution box 18. The drying hood 19 is used to concentrate the distributed hot airflow and blow it onto the surface of the label paper.
[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a motor 5 is fixedly connected to the outside of the machine body 1. The motor 5 provides power for position adjustment. A threaded rod 6 is fixedly connected to the output end of the motor 5. The other end of the threaded rod 6 is rotatably connected to the inside of the machine body 1. A slider 8 is threadedly connected to the outside of the threaded rod 6. The threaded rod 6 drives the slider 8 to move along its axial direction by rotating.
[0020] like Figure 3 As shown, both sides of the slider 8 are slidably connected to the outside of the guide rod 7. The guide rod 7 limits the movement direction of the slider 8 to prevent the slider 8 from rotating with the threaded rod 6. Both ends of the guide rod 7 are fixedly connected to the inside of the machine body 1 to ensure the installation stability of the guide rod 7.
[0021] like Figure 3 As shown, a mounting bracket 9 is fixedly connected to the bottom of the slider 8. The mounting bracket 9 is used to fix the electric telescopic rod 10. The electric telescopic rod 10 is fixedly connected inside the mounting bracket 9. The electric telescopic rod 10 can extend and retract in the vertical direction to adjust the height.
[0022] like Figure 3 As shown, the output end of the electric telescopic rod 10 is fixedly connected to a correction plate 11. The correction plate 11 is used to abut against the side of the label paper to correct the offset. The inner side of the correction plate 11 abuts against the outer side of the mounting roller 2 to realize real-time position correction of the label paper.
[0023] Working principle: like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a high-precision self-adhesive label paper processing equipment is used in which the self-adhesive label paper roll is first installed on the mounting roller 2. The mounting roller 2 is connected to the inside of the machine body 1 through the mounting rod 21 and is mounted on the placement frame 20 with the help of the mounting rod 22. The limiting plate 23 initially limits one side of the label paper roll to prevent it from shifting significantly laterally during rotation.
[0024] Subsequently, the label paper is conveyed along a preset path inside the machine body 1 under the guidance of the guide roller 3. During the conveying process, if the label paper is misaligned, the motor 5 starts and drives the threaded rod 6 to rotate. Since the slider 8 is threadedly connected to the threaded rod 6 and is limited on both sides by the guide rod 7, the slider 8 will move smoothly along the axial direction of the threaded rod 6. At the same time, the electric telescopic rod 10 on the mounting frame 9 extends and retracts according to the width specification of the label paper, adjusting the height of the correction plate 11 so that the inner side of the correction plate 11 accurately abuts against the side of the label paper. The misalignment is corrected in real time through lateral thrust, ensuring that the label paper maintains a precise position to enter the next processing stage.
[0025] When the label paper is fed to the inkjet unit 4, the inkjet unit 4 accurately prints patterns or text on its surface. After printing, the label paper continues to be fed to the drying unit. At this time, the fan 15 in the heating box 13 starts, draws in external air and filters out impurities through the dust filter 14. The clean air is heated by the electric heating wire 16 to form a hot airflow. The hot airflow enters the air distribution box 18 through the connecting pipe 17. After being evenly distributed by the air distribution box 18, it is simultaneously blown onto the surface of the label paper by multiple drying hoods 19, so as to achieve rapid and uniform drying of the printed pattern and avoid smudging or rubbing of the undried pattern.
[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
