Description

Technical Field

[0001] This application relates to the field of label production equipment, and in particular to a vacuum hub telescopic mechanism for a laminating machine. Background Art

[0002] RFID laminating machines are core equipment in the RFID tag production process. They are primarily used to laminate the inlay (antenna and chip encapsulation) with other materials (such as face paper, backing paper, adhesive layer, protective film, etc.) to form composite materials. These composite materials are then die-cut into various specifications of finished RFID tags. The inlay is the output of the upstream RFID packaging equipment and the input raw material for the laminating machine. It is typically in roll form without adhesive and serves as the intercalating material in the composite material. In RFID laminating machines, the cutter and vacuum drum are two key components, each performing different functions. The cutter primarily cuts the continuous intercalating material to a preset size, forming individual inlay units for subsequent lamination with face paper, backing paper, or other materials. The vacuum drum is mainly used to adsorb and position the inlay, ensuring its stability and accuracy during the lamination process. The coordinated work of these two components is crucial for the efficient and high-precision production of RFID tag laminating machines.

[0003] In typical laminators, the width of the vacuum drum is determined by the maximum width of the backing paper the machine can process; the wider the backing paper, the wider the required vacuum drum. The vacuum drum width in laminators is usually pre-set to match the maximum width of the backing paper, ensuring it can adhere to the maximum distance between the top and bottom edges. Therefore, laminator vacuum drums are typically designed to be the maximum width of the backing paper. Regardless of the label width being processed, the maximum width vacuum drum is used. However, maintaining such a wide vacuum drum consumes more energy and is not conducive to long-term use and maintenance, thus there is still room for improvement. Summary of the Invention

[0004] To reduce energy consumption and facilitate use and maintenance, this application provides a vacuum hub telescopic mechanism for a composite machine.

[0005] The technical solution provided in this application for a vacuum hub telescopic mechanism for a composite machine is as follows:

[0006] A vacuum hub telescopic mechanism for a composite machine, comprising:

[0007] Hub rail, which extends along the width direction of the underlying material;

[0008] Mounting base, which is slidably connected to the hub rail and located above the bottom material;

[0009] A label feeding assembly, which is located at the feed end of the mounting base, is used to feed the intercalation material into the interior of the mounting base;

[0010] The cutting assembly and the vacuum hub assembly are both disposed inside the mounting base and distributed vertically, with a gap between them for the intercalation material to pass through. The cutting assembly is used to cut the intercalation material, and the vacuum hub assembly is used to adsorb and position the intercalation material, and to attach the intercalation material to the surface of the underlying material.

[0011] By adopting the above technical solution, the overall volume of the vacuum hub telescopic mechanism of the laminating machine is reduced. The vacuum hub assembly does not need to increase its width to accommodate the width of the underlying material, thus reducing the energy consumption required for vacuuming. Furthermore, the integration of the label feeding assembly, cutting assembly, and vacuum hub assembly into one unit improves overall rigidity and operational stability, enabling the equipment to operate smoothly at higher speeds. The vacuum hub telescopic mechanism adjusts the position of the mounting base according to the width of the underlying material, allowing the inlay material to be centered on the underlying material to meet lamination requirements, thus improving the equipment's adaptability. In addition, this design supports modular management, facilitating rapid switching and upgrades between different devices to meet the needs of various application scenarios, while significantly reducing maintenance costs and ease of use.

[0012] Preferably, the vacuum hub assembly includes a negative pressure drive component, a vacuum hub roller rotatably connected to the mounting base, a vacuum hub drive component for driving the vacuum hub roller to rotate, and an outer cylinder sleeved on the outer circumferential surface of the vacuum hub roller. The outer circumferential surface of the vacuum hub roller is provided with a plurality of circumferentially distributed chambers, and the outer cylinder is provided with a plurality of adsorption holes communicating with the chambers evenly distributed on its peripheral wall. The negative pressure drive component is used to evacuate air from the chambers to form a negative pressure.

[0013] By adopting the above technical solution, the vacuum hub assembly, through the setting of a negative pressure drive component, a vacuum hub roller, a vacuum hub drive component, and an outer cylinder with a chamber and adsorption holes, can accurately adsorb and position the intercalation material and stably adhere it to the surface of the underlying material, improving the accuracy and stability of the production process while reducing energy consumption. In addition, in the process of producing electronic tags in a laminating machine, high production speed and high efficiency are required, so the surface of the vacuum hub assembly is prone to wear, causing the label to detach and shift, and requiring replacement after long service life. By disassembling the vacuum hub assembly into a vacuum hub roller and an outer cylinder, the outer cylinder can be easily replaced. In addition, the outer cylinder can be disassembled into multiple arc-shaped plates and installed in a tile-like manner, thereby enabling targeted local replacement of the outer cylinder.

[0014] Preferably, the cutting assembly includes a cutting roller rotatably connected to the mounting base, a plurality of cutters disposed on the peripheral wall of the cutting roller, and a cutting motor for driving the cutting roller to rotate, wherein the plurality of cutters extend along the axial direction of the cutting roller and are distributed circumferentially along the cutting axis.

[0015] By adopting the above technical solution, the cutting assembly can efficiently complete the precise cutting of the inlay material by arranging several cutters on the peripheral wall of the cutting roller and cooperating with the cutting motor drive, ensuring the accuracy of the cutting size and position, meeting the error requirement within ±0.2mm, and improving product quality and production efficiency.

[0016] Preferably, the outer circumferential surface of the cutting roller is provided with a plurality of mounting grooves, the mounting grooves being used to mount the cutter, and the cutting edge of the cutter extending out of the mounting groove.

[0017] By adopting the above technical solution, several mounting grooves are provided on the outer circumference of the cutting roller. The cutter is mounted using these grooves, with its cutting edge extending beyond the grooves, thereby achieving precise cutting of the laminated material. This design ensures stable installation of the cutter while facilitating adjustment and replacement, thus improving cutting accuracy and work efficiency.

[0018] Preferably, the label feeding assembly includes a label feeding drive roller rotatably connected in the mounting groove, a label feeding motor for driving the label feeding drive roller to rotate, a sliding frame slidably connected in the mounting base, and a label feeding driven roller rotatably connected in the sliding frame. The distance between the label feeding drive roller and the label feeding driven roller can be adjusted according to the layer thickness.

[0019] By adopting the above technical solution, the label feeding component achieves flexible adjustment. Specifically, the distance between the active label feeding roller and the driven label feeding roller can be adjusted in real time according to the thickness of the intercalation material, thereby adapting to the conveying needs of intercalation materials of different specifications. This design not only improves the compatibility of the equipment but also ensures the stability of the intercalation material during transmission, avoiding jamming or offset problems caused by thickness differences, thus improving the overall working efficiency and product quality of the laminating machine.

[0020] Preferably, the mounting base is provided with a lifting component for driving the sliding frame to move radially toward the label feeding drive roller.

[0021] By adopting the above technical solution, the mounting base is equipped with a lifting component to drive the sliding frame to move radially toward the label feeding drive roller, which allows for flexible adjustment of the distance between the label feeding driven roller and the label feeding drive roller. This design enables the equipment to adapt to interlayer materials of different thicknesses, improves the compatibility of the laminating machine with diverse materials, reduces the production failure rate caused by changes in material thickness, and thus improves the overall stability and efficiency of production.

[0022] Preferably, the mounting base is provided with a guide for guiding the intercalation material, and the guide is connected in the gap between the cutting assembly and the vacuum hub assembly, as well as in the gap between the label feeding drive roller and the label feeding driven roller.

[0023] By adopting the above technical solution, the guide component can accurately guide the transmission path of the intercalation material inside the laminating machine, ensuring a smooth transition between the gaps between the cutting assembly and the vacuum hub assembly, as well as between the active and driven label feeding rollers. This design effectively improves the stability of the intercalation material throughout the entire processing, reduces the scrap rate caused by material misalignment, and improves the accuracy of cutting and adsorption positioning, thereby ensuring the consistency of the final RFID tag product quality.

[0024] Preferably, the guide includes two guide plates distributed vertically, with a gap between the two guide plates allowing the intercalating material to pass through. Each of the two guide plates has a plurality of guide strips at one end facing the label feeding assembly. The outer circumferential surface of the label feeding drive roller and the outer circumferential surface of the label feeding driven roller are provided with a plurality of axially distributed annular grooves. The plurality of guide strips correspond one-to-one with the plurality of annular grooves, and the guide strips pass through the corresponding annular grooves.

[0025] By adopting the above technical solution, the gap between the two guide plates ensures that the intercalation material passes through smoothly and avoids deviation. The guide strip cooperates with the annular groove on the label feeding drive roller and the label feeding driven roller, further enhancing the stability of material transmission and reducing the risk of material jamming or misalignment, thereby improving the reliability and efficiency of the entire composite process.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The vacuum hub telescopic mechanism of the laminating machine achieves position adjustment through a sliding connection on the hub track, which can be adapted to different base paper widths, thereby significantly reducing the size of the equipment and lowering the installation requirements;

[0028] 2. The vacuum hub assembly adopts an optimized chamber and adsorption hole structure, which, together with the negative pressure drive component, forms a highly efficient adsorption system, significantly reducing energy consumption while ensuring adsorption force.

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0039] This application discloses a vacuum hub telescopic mechanism for a composite machine, referring to... Figure 1 The laminating machine is driven by an electrical control cabinet. When producing labels, it feeds materials through the steps of inlay unwinding, fabric unwinding, and base material unwinding. At the same time, it collects waste fabric. The inlay, fabric, and base material are laminated at the laminating drive mechanism. The die-cutting knife cuts the composite material. Finally, the finished product is rolled up. During production, the roll material is conveyed through the base material drive shaft, laminating drive shaft 1, and laminating drive shaft 2. The base material is processed through hot melt glue gun 1, hot melt glue gun 2, a guide device, and a base material buffer, thereby improving the overall processing quality.

[0040] Reference Figure 2 and Figure 3The vacuum hub telescopic mechanism includes a hub track 4, a mounting base 3, a label feeding assembly 6, a cutting assembly 7, and a vacuum hub assembly 5. The hub track 4 extends along the width of the base material 2. The mounting base 3 is slidably connected to the hub track 4 and located above the base material 2. The label feeding assembly 6 is located at the feed end of the mounting base 3 for introducing the intercalation material 1. The cutting assembly 7 and the vacuum hub assembly 5 are both located inside the mounting base 3 and are distributed vertically. The gap between them allows the intercalation material 1 to pass through. The former is responsible for precisely cutting the intercalation material 1, while the latter is used to adsorb and accurately position the intercalation material 1 and transfer it to the surface of the base material. This design achieves modular and flexible assembly and significantly improves operational efficiency. In this embodiment, the intercalation material 1 is a continuous inlay material, and the base material 2 uses continuous backing paper.

[0041] In this embodiment, the hub track 4 primarily employs a linear guide rail. It can be made of aluminum with a rectangular cross-section and securely fixed to the side of the fuselage frame using high-strength steel bolts, with stainless steel chosen to enhance corrosion resistance. The hub track 4 is positioned above the underlying material 2.

[0042] In this embodiment, the main body of the mounting base 3 is generally made of cast iron, as it possesses excellent mechanical properties such as high wear resistance, making it very suitable for this type of application. Furthermore, to reduce weight, magnesium alloy casting can be used in certain areas to achieve lightweighting. The movement of the mounting base 3 can be driven by a linear module or a cylinder power element.

[0043] In this embodiment, the label feeding assembly 6 includes a label feeding drive roller 61, a label feeding driven roller 62, a sliding frame 63, and a label feeding motor 65. Specifically, the label feeding drive roller 61 is rotatably connected to the mounting base 3, and the axial direction of the label feeding drive roller 61 is aligned with the width direction of the underlying material 2. The sliding frame 63 is located above the label feeding drive roller 61 and is slidably connected to the mounting base 3 along the radial direction of the label feeding drive roller 61. The label feeding driven roller 62 is parallel to the label feeding drive roller 61 and rotatably connected within the sliding frame 63. In addition, the mounting base 3 is equipped with a lifting component 64, which drives the sliding frame 63 to move radially toward the label feeding drive roller 61. The lifting component 64 is specifically a cylinder, allowing the distance between the label feeding drive roller 61 and the label feeding driven roller 62 to be adjusted according to the intercalation thickness.

[0044] Reference Figures 4 to 6In this embodiment, the vacuum hub assembly 5 includes a negative pressure drive component, a vacuum hub roller 52 rotatably connected to the mounting base 3, a vacuum hub drive component 51 for driving the vacuum hub roller 52 to rotate, and an outer cylinder 53 sleeved on the outer circumferential surface of the vacuum hub roller 52. The vacuum hub drive component 51 is a motor that drives the vacuum hub roller 52 to rotate. The outer circumferential surface of the vacuum hub roller 52 is provided with a plurality of circumferentially distributed chambers 521, which extend along the axial direction of the vacuum hub roller 52. The outer cylinder 53 is provided with a plurality of suction holes 531 evenly distributed on its peripheral wall, which communicate with the chambers 521. The negative pressure drive component is used to evacuate air from the inside of the chambers 521 to form a negative pressure. The negative pressure drive component can be a vacuum pump or a vacuum fan. The pipe of the vacuum fan is connected to the internal pipe of the vacuum hub roller 52 through a rotary joint and is connected to each chamber 521 to facilitate the formation of a stable negative pressure state in each chamber 521. The adsorption hole 531 is an elongated hole. By adopting a vacuum hub design with an elongated hole on the panel, the adsorption force of the vacuum hub can be effectively increased. In addition, the actual adsorption effect can be improved by optimizing and shortening the pipeline, increasing the pipe diameter, improving the smoothness of the inner wall, and reducing leakage pressure loss. By reducing the volume of the vacuum hub assembly 5 and optimizing the structure of each component, the vacuum fan is reduced from the original 2.2KW to 700W, resulting in an overall reduction in energy consumption.

[0045] Because the production of electronic tags in a laminating machine requires high speed and efficiency, the surface of the vacuum hub assembly 5 is prone to wear, causing label detachment and displacement, necessitating replacement after prolonged use. Considering sealing performance and machining processes, a surface-replaceable vacuum hub assembly 5 is adopted. The vacuum hub assembly 5 is disassembled into a vacuum hub roller 52 and an outer cylinder 53 to facilitate replacement of the outer cylinder 53. Furthermore, the outer cylinder 53 can be disassembled into multiple arc-shaped plates, using a tile-like installation, allowing for targeted replacement of the outer cylinder 53 by loosening the screws of the corresponding arc-shaped plates.

[0046] Reference Figure 4 and Figure 7In this embodiment, the cutting assembly 7 includes a cutting roller 73, multiple cutters 72, and a corresponding drive device, namely a cutting motor 71. The cutting roller 73 should be forged from a special steel with extremely high hardness to ensure reliable performance under long-term high-frequency operation. The permanent magnet synchronous cutting motor 71 is selected not only for its energy saving and environmental protection, but also for its rapid response and extremely high control precision to meet actual needs. In addition, the outer circumferential surface of the cutting roller 73 is provided with several mounting grooves 731, which are evenly spaced circumferentially distributed around the periphery of the cutting roller 73. The mounting grooves 731 are used to mount the cutters 72, and the cutting edge of the cutter 72 extends beyond the mounting grooves 731, ensuring that the cutter 72 is securely mounted while facilitating adjustment and replacement of the cutter 72, thereby improving cutting accuracy and work efficiency. It is particularly noteworthy that the cutter 72 can be precisely adjusted in both the axial and radial directions of the cutting roller 73, ensuring cutting accuracy and consistency. When the cutting assembly 7 is working, the cutting roller 73 and the vacuum hub roller 52 rotate synchronously, cutting the continuous roll of inlay material 1 according to a preset size to form a single inlay unit. Equipped with photoelectric sensor control for positioning, it is required to ensure the accuracy of the cutting size and position, with an error within ±0.2mm. The cutter 72 must be precisely installed. The cutting edge of the cutter 72 is balanced, and when cutting the inlay material 1 on the surface of the outer cylinder 53, the cutting edge of the cutter 72 is perpendicular to the inlay material 1 to achieve precise cutting.

[0047] Reference Figure 3 and Figure 4 In this embodiment, a guide member 8 is also installed inside the mounting base 3 to connect the gap between the cutting assembly 7 and the vacuum hub assembly 5, as well as the gap between the label feeding drive roller 61 and the label feeding driven roller 62. The guide member 8 includes two vertically distributed guide plates 81. The gap between the two guide plates 81 allows the intercalation material 1 to pass through, ensuring that the intercalation material 1 passes through smoothly and avoids deviation. In addition, each of the two guide plates 81 has a number of guide strips 82 at the end facing the label feeding assembly 6. The outer circumferential surfaces of the label feeding drive roller 61 and the label feeding driven roller 62 are provided with a number of axially distributed annular grooves 9. The number of guide strips 82 corresponds one-to-one with the number of annular grooves 9, and the guide strips 82 pass through the corresponding annular grooves 9. The guide strips 82 cooperate with the annular grooves 9 on the label feeding drive roller 61 and the label feeding driven roller 62, further enhancing the stability of the transmission of the intercalation material 1, reducing the risk of material jamming or misalignment, thereby improving the reliability and efficiency of the entire composite process.

[0048] The implementation principle of this embodiment is as follows: This mechanism integrates various functional components into a single unit, allowing it to move and adjust its position within a certain range to adapt to variations in the width of different base paper materials. This not only reduces the overall size of the equipment but also simplifies the operation process and improves work efficiency. In particular, it represents a significant leap forward in energy consumption, effectively reducing operating costs. Furthermore, the unique 53mm long-hole design on the outer cylinder panel increases the effective adsorption area, further enhancing adsorption efficiency and providing a strong guarantee for high-quality product output.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
