Description

Technical Field

[0001] This utility model relates to the field of tag winding technology, and more specifically to an RFID tag collection roll device. Background Technology

[0002] RFID tags, or Radio Frequency Identification tags, are electronic tags that communicate with readers without contact via radio waves. Structure: They typically include an antenna, a chip, and encapsulation materials. The antenna receives and transmits radio waves, the chip stores data and processes signals, and the encapsulation material protects the tag and adapts to different environments. Working principle: Based on electromagnetic induction or backscattering coupling. Passive tags obtain energy from the reader's electromagnetic field, while active tags have their own power supply and can actively transmit signals.

[0003] The shortcomings of existing technology are: existing label collection cylinders can only wind up labels of a fixed width when winding up label paper, and cannot be adjusted according to the width of the label, which affects the winding of the label. In addition, it is not convenient to disassemble the roller when unloading the RFID label after winding, which affects the unloading efficiency of the RFID label roll.

[0004] Therefore, there is a need to provide an RFID tag collection roll device to solve the problems mentioned above. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an RFID tag collection roll device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an RFID tag collection roll device, comprising two supports, a first roll movably sleeved near the top of one support, and a second roll movably sleeved near the middle of the top of the other support, a lead screw movably sleeved in the middle of both the first and second rolls, threaded blocks threadedly sleeved on the outer walls of the two lead screws, a set of sliders fixedly connected to the outer walls of the two threaded blocks, adjusting plates fixedly connected to the top and bottom ends of the two sets of sliders, and the middle of the two adjusting plates movably sleeved on the outer walls of the first and second rolls;

[0007] The RFID tag collection roll device also includes:

[0008] An adjustment motor is provided, which is located on the left side of a bracket and is used to drive the lead screw to rotate.

[0009] A winding motor is located on the right side of the other side bracket and is used to drive the adjustment plate to rotate.

[0010] Preferably, the inner wall of the first drum near the right end is provided with a threaded groove, and the left end of the second drum is fixedly connected with a threaded sleeve rod, the outer wall of the threaded sleeve rod being threadedly engaged with the threaded groove.

[0011] Preferably, a fixing block is fixedly connected to the left end of the lead screw in the second drum, and a trapezoidal locking block is fixedly connected to the left side of the fixing block. A locking slot is fixedly connected to the right end of the lead screw in the first drum, and the outer wall of the trapezoidal locking block is movably locked in the locking slot.

[0012] Preferably, the top and bottom ends of the first and second rolls are provided with sliding grooves, and the outer walls of the four sliders are slidably connected in the sliding grooves.

[0013] Preferably, the left end of the lead screw passes through a bracket and is fixedly connected to the transmission end of the adjusting motor, and the outer wall of the adjusting plate passes through another bracket and is fixedly connected to the transmission end of the winding motor.

[0014] Preferably, a set of two sliders is used, and the opposite sides of the two sliders are fixedly connected to the outer wall of the threaded sleeve block.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model, by providing an adjusting plate, allows for the winding of RFID tags of different widths. With the support of the bracket, the adjusting motor is turned on, driving the lead screw to rotate within the first and second drums. Subsequently, under the movable limit of the slider, the threaded sleeve block moves on the outer wall of the lead screw, thereby causing the two adjusting plates fixed to the slider to move relative to or towards each other on the outer walls of the first and second drums. The slider slides within the groove as the threaded sleeve block moves, which is beneficial for limiting the RFID tags of different widths on the outer walls of the first and second drums, thus enabling rapid winding of the RFID tags.

[0017] 2. This utility model, by providing a slot seat and a trapezoidal locking block, allows for the following when disassembling the first and second rolls: under the fixed connection of the fixing block, the outer wall of the trapezoidal locking block is locked in the slot seat, thereby locking and connecting the two lead screws inside the second and first rolls. Rotating one end of the second roll causes the threaded sleeve to engage with the threaded groove on the inner wall of the first roll, which facilitates the quick connection of the first and second rolls. It also facilitates the quick separation of the first and second rolls when disassembling RFID tag rolls, thus improving the disassembly efficiency of RFID tag rolls. Attached Figure Description

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The RFID tag collection roll device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Specific Implementation Example 1

[0025] Please see Figure 1-3 This utility model relates to an RFID tag collection reel device, comprising two supports 5. A first reel 3 is movably sleeved near the top of one support 5, and a second reel 4 is movably sleeved near the middle of the top of the other support 5. Lead screws 10 are movably sleeved at the middle of both the first and second reel 3. Threaded sleeve blocks 9 are threaded onto the outer walls of the two lead screws 10. A set of sliders 8 is fixedly connected to the outer walls of both threaded sleeve blocks 9. Adjusting plates 2 are fixedly connected to the top and bottom ends of the two sets of sliders 8. The middle of the two adjusting plates 2 is movably sleeved onto the outer walls of the first and second reel 3 and the second reel 4. The RFID tag collection reel device also includes... The adjustment motor 1 is located on the left side of a bracket 5 and is used to drive the lead screw 10 to rotate. The winding motor 6 is located on the right side of another bracket 5 and is used to drive the adjustment plate 2 to rotate. The top and bottom ends of the first drum 3 and the second drum 4 are both provided with sliding grooves 7. The outer walls of the four sliders 8 are slidably connected in the sliding grooves 7. The left end of the lead screw 10 passes through a bracket 5 and is fixedly connected to the transmission end of the adjustment motor 1. The outer wall of the adjustment plate 2 passes through another bracket 5 and is fixedly connected to the transmission end of the winding motor 6. There are two sliders 8 in a set. The opposite sides of the two sliders 8 are fixedly connected to the outer wall of the threaded sleeve block 9.

[0026] Specifically: Turn on the adjusting motor 1, which drives the lead screw 10 connected to it to rotate in the first drum 3 and the second drum 4. Then, under the limit of the movement of the slider 8, the threaded sleeve block 9 that is threadedly connected to it moves on the outer wall of the lead screw 10. This causes the two adjusting plates 2 that are fixed to the slider 8 to move relative to or towards each other on the outer walls of the first drum 3 and the second drum 4. The slider 8 slides in the groove 7 as the threaded sleeve block 9 moves. Specific Implementation Example 2

[0028] Please see Figure 1 and Figure 4 Based on the first specific embodiment, a threaded groove 301 is provided on the inner wall near the right end of the first drum 3, and a threaded sleeve rod 401 is fixedly connected to the left end of the second drum 4. The outer wall of the threaded sleeve rod 401 is threadedly connected to the threaded groove 301. A fixing block 12 is fixedly connected to the left end of the lead screw 10 in the second drum 4, and a trapezoidal locking block 13 is fixedly connected to the left side of the fixing block 12. A slot seat 11 is fixedly connected to the right end of the lead screw 10 in the first drum 3, and the outer wall of the trapezoidal locking block 13 is movably locked in the slot seat 11.

[0029] Specifically: Under the fixed connection of the fixed block 12, the outer wall of the trapezoidal card block 13 is locked in the card slot seat 11, and the two screw rods 10 in the second drum 4 and the first drum 3 are locked and connected. Rotating one end of the second drum 4 drives the threaded sleeve rod 401 to be threadedly engaged with the threaded groove 301 on the inner wall of the first drum 3.

[0030] The working principle of this utility model is as follows: Supported by two brackets 5, when winding RFID tags of different widths, the adjusting motor 1 is turned on, driving the lead screw 10 connected to it to rotate within the first drum 3 and the second drum 4. Then, under the limiting position of the slider 8, the threaded sleeve 9, which is threadedly connected to it, moves on the outer wall of the lead screw 10. This, in turn, causes the two adjusting plates 2 fixed to the slider 8 to move relative to or towards each other on the outer walls of the first drum 3 and the second drum 4. The slider 8 slides within the groove 7 as the threaded sleeve 9 moves, thus controlling the movement of the first drum 3 and the second drum 4. The RFID tags of different widths on the outer wall limit the movement of the first roll 3 and the second roll 4. When disassembling the first roll 3 and the second roll 4, the outer wall of the trapezoidal locking block 13 is locked in the locking slot seat 11 under the fixed connection of the fixing block 12. The two lead screws 10 inside the second roll 4 and the first roll 3 are locked and connected. Rotating one end of the second roll 4 drives the threaded sleeve rod 401 to be threadedly engaged with the threaded groove 301 on the inner wall of the first roll 3, so as to quickly connect the first roll 3 and the second roll 4. When disassembling the RFID tag roll, it is convenient to quickly separate the first roll 3 and the second roll 4.

[0031] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
