Description

Technical Field

[0001] This utility model belongs to the field of tag production, specifically, it relates to an RFID electronic tag production device. Background Technology

[0002] RFID electronic tags are a type of radio frequency identification technology that can identify specific targets and read and write related data through radio signals without requiring mechanical or optical contact between the identification system and the specific target.

[0003] Chinese Patent CN219312181U discloses an RFID electronic tag production device, comprising: a U-shaped frame, an extrusion assembly and a de-adhesion assembly disposed between the two side walls of the U-shaped frame, the de-adhesion assembly being disposed on one side of the extrusion assembly, a collection box disposed below the de-adhesion assembly, and a cleaning assembly disposed above the de-adhesion assembly; the de-adhesion assembly includes a mounting shaft and a saw blade, the mounting shaft being rotatably disposed between the two side walls of the U-shaped frame. This application achieves re-fixation of the saw blade by loosening the fixing bolts to adjust the position of the saw blade, and then tightening the fixing bolts to press against the mounting shaft, effectively solving the problem of adjusting the saw blade position according to the size of the electronic tag tape. However, in practical applications, when the fixing bolts first contact the mounting shaft, it is difficult to fix the saw blade, so it is necessary to continue tightening the fixing bolts to make the fixing bolts tightly press against the mounting shaft. However, during this operation, the rotating fixing bolts are prone to causing frictional damage to the surface of the mounting shaft, thereby affecting the service life of the mounting shaft. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an RFID electronic tag production device, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] An RFID electronic tag production device, comprising:

[0007] The frame has a mounting shaft that rotates within it.

[0008] Two sliding blocks are slidably fitted around the mounting shaft, and saw blades are mounted on the periphery of the sliding blocks; two clamping blocks that hold the mounting shaft are slidably fitted on one side of the sliding blocks.

[0009] A connecting plate and two sliders are elastically and slidably fitted within a sliding block, with a connecting block installed between the sliders and the clamping block; wherein, a trapezoidal groove is provided on one side of the slider adjacent to the connecting plate, and trapezoidal blocks located within the trapezoidal groove are provided on both sides of one side of the connecting plate; and

[0010] The threaded part is fitted with a hand-tightening screw on the upper part of the sliding block, and the end of the hand-tightening screw abuts against one side of the connecting plate.

[0011] Optionally, a collection box is placed below the mounting shaft.

[0012] Optionally, a first spring for resetting is installed between the two sliders.

[0013] Optionally, both the trapezoidal groove and the trapezoidal block have right-angled trapezoidal cross sections.

[0014] Optionally, a fixed pressing mechanism is installed at the lower part of the frame, and a movable pressing mechanism is installed at the upper part of the frame.

[0015] Optionally, the fixed pressing mechanism includes a first rod that is rotatably fitted within the frame, and a lower roller is mounted on the periphery of the first rod.

[0016] Optionally, the movable pressing mechanism includes a lifting frame that is slidably fitted inside the frame, an upper rotating roller that is rotatably fitted between the two sides of the inner wall of the lower part of the lifting frame, an electric push rod that is installed on the upper side of the frame, and the output shaft of the electric push rod that is fixedly fitted on the upper side of the lifting frame.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0018] By rotating the hand-tightening screw to press or release the connecting plate, the trapezoidal block slides within the trapezoidal groove. The inclined plane pressing controls the synchronous opening and closing of the two sliders, facilitating quick release or locking of the clamping block on the mounting shaft, and enabling flexible adjustment of the saw blade's axial position. The clamping block increases the contact area between the hand-tightening screw and the mounting shaft, improving the stability of the saw blade during operation, while reducing the probability of wear on the mounting shaft surface caused by the rotation of the hand-tightening screw.

Detailed Implementation

[0036] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Please see Figure 1-4 As shown, this embodiment provides an RFID electronic tag production apparatus, including:

[0038] Frame 1, with mounting shaft 401 rotatably fitted inside frame 1;

[0039] Two sliding blocks 5 are slidably fitted around the mounting shaft 401, and a saw blade 501 is mounted around the periphery of the sliding block 5. The diameter of the saw blade 501 is 80-120mm and the thickness is 0.5-1.2mm. Two clamping blocks 704 are slidably fitted on one side of the sliding block 5 to clamp the mounting shaft 401. The arc face of the clamping block 704 in contact with the mounting shaft 401 is ≥90° and the axial length is ≥20mm, to ensure uniform distribution of clamping force and avoid local stress concentration.

[0040] A connecting plate 9 and two sliders 7 are elastically and slidably fitted within a sliding block 5. A connecting block 703 is installed between the sliders 7 and the clamping block 704. A trapezoidal groove 701 is provided on one side of the slider 7 adjacent to the connecting plate 9, and trapezoidal blocks 901 located within the trapezoidal groove 701 are provided on both sides of one side of the connecting plate 9.

[0041] The screw 6 is threaded onto the upper part of the sliding block 5 and the end of the screw 6 abuts against one side of the connecting plate 9.

[0042] Optionally, a first motor 4 is installed on the side of the frame 1. The output shaft of the first motor 4 is fixedly fitted to the end of the mounting shaft 401. The power of the first motor 4 is ≥200W and the speed is 2000-3000rpm, so that the linear speed of the saw blade 501 meets the cutting requirements.

[0043] One application of this embodiment is as follows: First, the hand-tightening screw 6 is unscrewed outwards towards the sliding block 5 to release the hand-tightening screw 6 from its contact with the connecting plate 9. At this time, the connecting plate 9, under the action of elasticity, drives the trapezoidal block 901 to slide back to its original position, so that the trapezoidal block 901 gradually releases its pressure on the wall of the trapezoidal groove 701. Subsequently, the two sliders 7 slide to both sides under the action of elasticity, and drive the clamping block 704 to move through the connecting block 703, thereby releasing the clamping block 704 from the mounting shaft 401. Next, the sliding block 5 can be pushed along the mounting shaft 401. The axial movement of 1 adjusts the position of the saw blade 501; after adjustment, the hand-tightening screw 6 is rotated in the opposite direction to press the connecting plate 9 to slide, and the inclined surface of the trapezoidal block 901 presses the two sliders 7 closer to each other, completing the clamping and fixing of the mounting shaft 401 by the clamping block 704; during the process of the RFID electronic tag tape being conveyed through the frame 1, the first motor 4 is controlled to drive the mounting shaft 401 to rotate, thereby driving the saw blade 501 to rotate, realizing the cutting of excess glue on both sides of the RFID electronic tag tape by the saw blade 501. It should be noted that all electrical equipment involved in this application can be powered by a storage battery or an external power source.

[0044] By rotating the hand screw 6 to press or release the pressure on the connecting plate 9, the trapezoidal block 901 slides within the trapezoidal groove 701. The inclined plane pressure controls the synchronous opening and closing of the two sliders 7, facilitating the quick release or locking of the clamping block 704 on the mounting shaft 401, thus enabling flexible adjustment of the axial position of the saw blade 501. The clamping block 704 increases the contact area between the hand screw 6 and the mounting shaft 401, improving the stability of the saw blade 501 during operation, while reducing the probability of wear on the surface of the mounting shaft 401 caused by the rotation of the hand screw 6.

[0045] like Figure 2 As shown, a collection box 8 is placed below the mounting shaft 401 in this embodiment. By setting up the collection box 8, it is convenient to collect the glue waste generated during cutting, reducing the interference of waste accumulation on equipment operation.

[0046] like Figure 3 , 4 As shown, in this embodiment, a first spring 702 for resetting is installed between the two sliders 7. Optionally, the slider 5 is provided with a movable groove 504, and the first spring 702, the connecting plate 9, and the trapezoidal block 901 are all located in the movable groove 504. The two sides of the slider 5 are respectively provided with screw holes 502 communicating with the movable groove 504 and two sliding grooves 503. The movable groove 504 is located between the two sliding grooves 503. The threaded part of the shank of the hand-tightening screw 6 is threaded in the screw hole 502. The two ends of the slider 7 are respectively located in the movable groove 504 and the sliding groove 503, and the connecting block 703 is located in the sliding groove 503. Optionally, a second spring 902 is installed between the connecting plate 9 and one side of the movable groove 504. The second spring 902 is located on the periphery of the hand-tightening screw 6, and the connecting plate 9 is located between the second spring 902 and the first spring 702. The first spring 702 rebounds and pushes the two sliders 7 away from each other, which facilitates the quick release of the clamping block 704 from the mounting shaft 401; the movable groove 504 integrates the limiting and guiding functions, and the screw hole 502 and the slide groove 503 respectively constrain the movement trajectory of the hand-tightening screw 6 and the slider 7, thereby improving the stability of the adjustment of the connecting plate 9, the trapezoidal block 901 and the slider 7.

[0047] like Figure 4 As shown, in this embodiment, the cross-sections of the trapezoidal groove 701 and the trapezoidal block 901 are both right-angled trapezoids, and the width of the trapezoidal block 901 gradually narrows from the connecting plate 9 to the clamping block 704. The inclined angle is 15° to 30°, reducing the probability of self-locking and difficulty in resetting due to an excessively small angle, and affecting the efficiency of force transmission due to an excessively large angle. By utilizing the inclined surface of the right-angled trapezoid and the gradually narrowing direction, the thrust of the connecting plate 9 is converted into a clamping force that drives the two sliders 7 to approach each other, improving the stability and synchronization of the clamping force transmission.

[0048] like Figure 1-2 As shown, in this embodiment, a fixed pressing mechanism 2 is installed at the lower part of the frame 1, and a movable pressing mechanism 3 is installed at the upper part of the frame 1.

[0049] Optionally, the fixed pressing mechanism 2 includes a first rod 202 rotatably fitted within the frame 1, with a lower rotating roller 203 mounted around the periphery of the first rod 202. Optionally, a second motor 201 is mounted on one side of the frame 1, with the output shaft of the second motor 201 fixedly fitted to the end of the first rod 202. The second motor 201 drives the first rod 202 to rotate, thereby causing the lower rotating roller 203 to rotate.

[0050] Optionally, the movable pressing mechanism 3 includes a lifting frame 302 slidably fitted within the frame 1. Both the frame 1 and the lifting frame 302 have inverted U-shaped vertical cross-sections. An upper rotating roller 304 is rotatably fitted between the two sides of the lower inner wall of the lifting frame 302. Optionally, a second rod 303 is installed between the two sides of the inner wall of the lifting frame 302, and the upper rotating roller 304 is rotatably fitted around the second rod 303. Optionally, grooves 101 are provided on both sides of the inner wall of the frame 1, and protrusions slidably fitted within the grooves 101 are provided on both sides of the lifting frame 302. Optionally, an electric push rod 301 is installed on the upper side of the frame 1. The output shaft of the electric push rod 301 is fixedly fitted to the upper side of the lifting frame 302. The stroke of the electric push rod 301 is 50-100mm, and the thrust is ≥200N, meeting the conventional RFID electronic tag tape thickness and composite pressure requirements. The height of the lifting frame 302 is adjusted by operating the electric push rod 301, so that the upper roller 304 and the lower roller 203 apply pressure to the face paper, back paper and middle material between them, conveying and extruding them to form an RFID electronic tag tape; then, the subsequent equipment pulls or winds it up, and the saw blade 501 is used to cut off the excess adhesive on both sides of the taut RFID electronic tag.
