Description

Technical Field

[0001] This utility model relates to the field of label slitting machines, specifically to a multifunctional RFID electronic tag slitting and laminating equipment. Background Technology

[0002] The main shortcomings of existing RFID tag cutting equipment include the following aspects:

[0003] 1. The slicing method is too simplistic and prone to problems:

[0004] Most slitting equipment on the market uses circular blades, which often generates a lot of dust during the cutting process, resulting in uneven slit edges and burrs. Furthermore, the blades are prone to adhesive buildup, requiring frequent wiping, which not only affects production efficiency but also increases maintenance costs. Moreover, this type of process is prone to damaging the die when cutting PET material, requiring regular replacement and further increasing production costs.

[0005] II. Poor adaptability to cutting different materials:

[0006] RFID electronic tags can be slit from a variety of materials, including paper, PET, laminated adhesive products, and laminated adhesive products. However, most slitting equipment on the market typically only supports either circular blade slitting or blade slitting, making it difficult to adapt to the slitting needs of different materials. Furthermore, when the antenna material is PET film, blade slitting after lamination is more effective, but paper slitting commonly uses upper and lower circular blades. This necessitates frequent adjustments to the equipment when switching between different materials, reducing production efficiency.

[0007] III. Inability to count and inadequate static electricity control:

[0008] RFID tags often require counting during slitting, meaning the machine stops once a certain quantity is reached. Currently, few slitting machines incorporate this counting feature. Furthermore, static electricity is easily generated during high-speed operation and friction. Chips are highly sensitive to static electricity, and ordinary slitting equipment struggles to control it within the safe range of 2KV. The presence of static electricity can not only damage the chip but also affect the stability and accuracy of the slitting process.

[0009] 4. Insufficient chip protection: Dry inlay consists of PET substrate + etched aluminum foil antenna + bare chip directly packaged, lacking a buffer layer. When there is unstable or large fluctuation in winding tension, the chip may be squeezed, which may lead to chip breakage and damage. Most slitting equipment on the market uses direct winding and only avoids overlapping through tension control. It does not have the function of embedding backing paper and cannot protect the chip well. Utility Model Content

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] like Figures 1 to 8 As shown in the figure, this embodiment discloses a multifunctional RFID electronic tag slitting and coating equipment, including an unwinding unit 1, a coating unit 2, a slitting unit 3 and a rewinding unit 4. The material formed by the raw material output from the unwinding unit 1 and the film output from the coating unit 2 is fed into the slitting unit 3 for slitting, and the rewinding unit 4 rewinds the material output from the slitting unit 3.

[0037] like Figure 6The slitting unit 3 includes a circular blade slitting module 31 and a straight blade slitting module 32. The circular blade slitting module 31 includes an upper blade shaft 311, a lower blade shaft 312, and a first drive mechanism 315 for driving the upper blade shaft 311 and the lower blade shaft 312 to rotate. The upper blade shaft 311 is equipped with a set of spaced upper circular blades 313, and the lower blade shaft 312 is equipped with a set of spaced lower circular blades 314. The upper circular blades 313 and the lower circular blades 314 work together to cut. The straight blade slitting module 32 includes a set of spaced straight blades 321. Different slitting blades are used for the composite material depending on the material. For paper materials such as glassine, the circular blade slitting module 31 is used for cutting. For PET-like materials such as inlay and POPP film, the straight blade slitting module 32 is used for cutting. By integrating the circular blade slitting module 31 and the straight blade slitting module 32 into the same device, it is possible to cut different types of materials, improve the versatility of the device, and only one set of unwinding unit 1, coating unit 2 and rewinding unit 4 is required.

[0038] Preferably, the upper circular blade 313 is detachable, or the lower circular blade 314 is detachable, or both the upper circular blade 313 and the lower circular blade 314 are detachable. When cutting PET-like materials such as inlay and POPP film, the circular blade slitting module 31 is removed, and then the straight blade slitting module 32 is used for cutting. In this way, the material does not need to avoid the circular blade slitting module 31, and the circular blade slitting module 31 and the straight blade slitting module 32 can be arranged more compactly.

[0039] The first drive mechanism 315 includes a servo motor, a first gear 317, and a second gear 316. The first gear 317 and the second gear 316 mesh with each other. The first gear and the second gear are respectively mounted on the upper tool shaft 311 and the lower tool shaft 312. The servo motor is connected to either the upper tool shaft 311 or the lower tool shaft 312, and drives the upper tool shaft 311 and the lower tool shaft 312 to rotate synchronously. In other examples, the first drive mechanism 315 may also adopt other structures, for example, a belt-gear transmission mechanism.

[0040] like Figure 4 The unwinding unit 1 includes an adjustment component and an unwinding component. The unwinding component includes an unwinding bracket 19 and an unwinding air shaft 17 and a guide roller 111 mounted on the unwinding bracket 19. A correction sensor 112 (specifically an ultrasonic sensor) and a counting sensor 113 are provided on one side of the guide roller 111. The guide roller 111 is located above the unwinding air shaft 17, and a magnetic adsorption plate 110 is provided below the guide roller 111.

[0041] The unwinding air shaft 17 is equipped with a second drive mechanism. Specifically, the second drive mechanism includes an unwinding motor 18, a synchronous belt 20, and a synchronous pulley 16. The synchronous pulley 16 is sleeved on the unwinding air shaft 17, and the unwinding motor 18 drives the unwinding air shaft 17 to rotate through the synchronous belt 20 and the synchronous pulley 16.

[0042] The adjustment assembly includes a fixed base 13 and an electric push rod 11. Two (or more) guide rails 15 with sliders 14 are mounted on the fixed base 13. An unwinding bracket 19 is mounted on the sliders 14. The electric push rod is mounted on the fixed base and connected to the unwinding bracket. The electric push rod 11 drives the unwinding bracket 19 to move axially along the unwinding air shaft 17. In other embodiments, the adjustment assembly is not limited to this. For example, the adjustment assembly may include a lead screw, a slider, and a servo motor. The servo motor drives the lead screw to rotate, and the slider is fitted onto the lead screw and connected to the unwinding bracket.

[0043] Raw materials (such as inlays, antennas, or paper) are placed at the position of the unwinding air shaft 17, pass through the guide roller 111, and the edge position of the material is monitored in real time by the correction sensor 112. The offset signal is detected and transmitted to the controller of the equipment (using a PLC control system). The controller controls the electric push rod 11 to move the entire unwinding bracket 19. In addition, the unwinding motor 18 drives the unwinding air shaft 17 to rotate through the synchronous belt and synchronous pulley 16 to ensure that the material moves and the paper is fed evenly. At the same time, the unwinding motor 18 controls the speed of the unwinding air shaft 17 by setting torque parameters to control the tension and ensure that the conveying is not too loose or too tight.

[0044] When changing material rolls, a magnet is placed at the magnetic adsorption plate 110 to clamp the material, and then the material is joined together (the front and rear sections of material are overlapped together) to prevent the material conveyor belt from shifting and affecting the correction position.

[0045] like Figure 2 and Figure 5 The laminating unit 2 includes a composite film unwinding shaft 21, a composite film backing paper take-up shaft 22, a guide roller 25, a peeling roller assembly, a laminating roller assembly, and a feeding roller assembly. The composite film unwinding shaft 21 is connected to a third drive mechanism 23, and the composite film backing paper take-up shaft 22 is connected to a fourth drive mechanism 24. The peeling roller assembly has a composite film guide roller 26 and a backing paper peeling roller 27 spaced apart. The laminating roller assembly has a laminating pressure roller 31 and a laminating bottom roller 32. The feeding roller assembly includes a feeding pressure roller 28 and a feeding bottom roller 29, wherein the feeding bottom roller 29 is connected to a feeding servo motor 30 for driving it to rotate.

[0046] Both the third drive mechanism 23 and the fourth drive mechanism 24 include a servo motor, a synchronous belt, and synchronous pulleys. A synchronous pulley is mounted on each of the composite film unwinding shaft 21 and the composite film bottom paper take-up shaft 22. The servo motor drives the composite film unwinding shaft 21 or the composite film bottom paper take-up shaft 22 to rotate via the synchronous belt and synchronous pulleys. In other embodiments, the third drive mechanism 23 and the fourth drive mechanism 24 may also employ other structures. For example, the servo motor may be connected to the composite film unwinding shaft 21 or the composite film bottom paper take-up shaft 22 via a coupling, eliminating the need for synchronous belts and synchronous pulleys.

[0047] Taking double-layer coated material as an example, the double-layer coated material is placed at the position of the composite film unwinding shaft 21, and then passes between the composite film guide roller 27 and the bottom paper peeling roller 26. The backing material is peeled off at the bottom paper peeling roller 26. The peeled backing material is collected on the composite film bottom paper winding shaft 22. The peeled adhesive face material passes between the coating pressure roller 31 and the coating bottom roller 32. The material conveyed by the unwinding unit 1 and the peeled adhesive face material are composited between the coating pressure roller 31 and the coating bottom roller 32. The resulting composite material passes through the feeding bottom roller 29 and the feeding pressure roller 28. The feeding servo motor 30 drives the feeding bottom roller 29 to rotate to convey the material to the slitting unit.

[0048] The slitting unit 3 also includes a slitting bracket 324 and two fixedly mounted slitting bracket moving guide shafts 320. The upper cutter shaft 311 and the lower cutter shaft 312 are mounted on the slitting bracket 324. The slitting bracket 324 is sleeved on the two slitting bracket moving guide shafts 320. The slitting bracket 324 can move along the axial direction of the slitting bracket moving guide shafts 320 to adjust the position of the slitting bracket 324 on the slitting bracket moving guide shafts 320.

[0049] Preferably, the upper blade shaft 311 can move axially relative to the slitting bracket 324, thereby moving the upper circular blade 313 to a position where it is appropriately close to the lower circular blade 314, ensuring that the cutting edges of the upper circular blade 313 and the lower circular blade 314 are in contact to cut the material. Preferably, in this embodiment, the lower blade shaft 312 can be detached from the slitting bracket, and the entire lower blade shaft 312 can be pulled out for easy installation and removal of the lower circular blade 314.

[0050] The slitting bracket 324 is also equipped with two opposing positioning rollers 318. The positioning rollers 318, the slitting bracket moving guide shaft 320, the upper cutter shaft 311 and the lower cutter shaft 312 are arranged in parallel.

[0051] The positioning roller 318, the upper cutter shaft 311, and the lower cutter shaft 312 are all mounted on the slitting bracket. When the position of the slitting bracket is adjusted, the positioning roller 318, the upper cutter shaft 311, and the lower cutter shaft 312 move together with the slitting bracket.

[0052] The composite material is slitting with different blades depending on its material composition. For paper materials such as glassine, the blade passes between the upper circular blade 313 and the lower circular blade 314. The servo motor of the first drive mechanism 315 drives the lower blade shaft to rotate, which in turn drives the upper blade shaft to rotate through the meshing of the first gear 317 and the second gear 316. The upper blade shaft is adjusted to move back and forth (along the axial direction) so that the upper and lower circular blades are properly close together, ensuring that the blades of the upper and lower circular blades contact the material for cutting. When disassembling the lower blade shaft 312, the entire lower blade shaft 312 is pulled out from the slitting bracket for easy loading and unloading of the lower circular blade. For PET-like materials such as inlay and popp film, a straight cutting blade is used for cutting. A blade fixing seat 322 is placed on the straight cutting blade fixing shaft 321, and a straight cutting blade is installed on the blade fixing seat 322. The blade fixing seat 322 is clamped on the straight cutting blade fixing shaft 321. By rotating the blade fixing seat 322, the angle of the straight cutting blade can be adjusted to ensure that the straight cutting blade can contact the material and achieve cutting. If a slitting position deviation is detected, the entire slitting frame 324 can be moved back and forth to adjust the slitting position.

[0053] like Figure 2 and Figure 7 The winding unit 4 includes a finished product guide roller 74, an upper finished product winding shaft 71, a lower finished product winding shaft 73, a liner paper placement shaft 77, a liner paper guide roller 79, and a liner paper guide plate 78. An anti-static bar 75 is provided below the finished product guide roller 74. The upper finished product winding shaft 71 is located above one side of the finished product guide roller 74, and the lower finished product winding shaft 73 is located below one side of the finished product guide roller 74. The upper finished product winding shaft 71 is connected to a fifth drive mechanism 72 that drives it to rotate, and the lower finished product winding shaft 73 is connected to a sixth drive mechanism 76 that drives it to rotate.

[0054] The liner guide plate 78 is installed on the liner placement shaft 77, and the finished product guide roller 74 is located above and to one side of the liner guide roller 79. The slit material first passes through the finished product guide roller 74, and at the same time, the static elimination bar 75 is turned on to eliminate the static electricity of the material. After that, the slit material is respectively conveyed to the upper finished product winding shaft 71 and the lower finished product winding shaft 73 to be wound up to form the product.

[0055] Both the fifth drive mechanism 72 and the sixth drive mechanism 76 include a servo motor, a synchronous belt, and a synchronous pulley. The upper finished product winding shaft 71 and the lower finished product winding shaft 73 are each equipped with a synchronous pulley. The winding tension is controlled by the torque mode of the servo motor. For inlay slitting, liner paper is placed on the liner paper placement shaft 77 and limited by the liner paper guide plate 78 to prevent deviation. The liner paper passes through the liner paper guide roller 79 and is inserted into the material being wound. A layer of liner paper is used to separate every two layers of material to prevent the chips on the adjacent two layers of material from being crushed by overlapping.

[0056] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model. Therefore, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
