Description
Technical Field
[0001] This application relates to the field of detection devices, and in particular to a temperature-sensitive label detection device. Background Technology
[0002] Thermochromic labels are anti-counterfeiting labels made with thermochromic ink. Their color changes rapidly with ambient temperature and are commonly used to verify product authenticity. They display a specific color or are colorless at room temperature, and exhibit dynamic color effects when the temperature rises or falls. They are divided into reversible (returning to the original color after heating) and irreversible (not returning to the original color after heating).
[0003] The utility model patent with announcement number CN217688173U proposes a label detection device based on temperature-sensitive anti-counterfeiting graphic printing hidden technology, including a detection box, a detection platform, and a bellows. The detection platform is installed at the bottom of the detection box, and a limit structure is set at the top of the detection platform. Adjustment structures are set on both sides of the detection box. A bellows is set on one side of the adjustment structure. A fan is installed on one side of the bellows, and an electric heating wire is installed on the other side of the bellows. A movable structure is set at the top of the detection box, and a detection head is set at the bottom of the movable structure.
[0004] One of the label detection devices based on thermochromic anti-counterfeiting graphic printing technology mentioned above allows the sleeve to move on the guide rod by loosening the adjusting bolt, thereby adjusting the position of the detection head to facilitate better product detection. However, when adjusting the position, the sleeve can only move left and right on the guide rod, which limits the adjustment range and reduces its applicability. Utility Model Content
[0005] To address the aforementioned issues, this application provides a temperature-sensitive label detection device.
[0006] The temperature-sensitive label detection device provided in this application adopts the following technical solution:
[0007] A temperature-sensitive label detection device includes a detection platform and a detection head. The detection platform is provided with a fixing component for placing temperature-sensitive labels, a heating component for heating the temperature-sensitive labels, and a moving component for adjusting the position of the detection head. The moving component includes a U-shaped frame fixedly connected to the top of the detection platform. Through grooves are opened on both side walls of the U-shaped frame. A slider is slidably disposed in each of the through grooves. A first threaded rod is rotatably connected between two of the sliders. A mounting block is threadedly connected to the first threaded rod. A lifting component is provided on the mounting block. The detection head is mounted on the lifting component. A second threaded rod is rotatably connected to one of the through grooves. The slider is threadedly connected to the second threaded rod.
[0008] By adopting the above technical solution, during use, rotating the first threaded rod causes the mounting block to move left and right on the first threaded rod, while rotating the second threaded rod causes the slider to move back and forth in the through groove. This allows the mounting block to move the detection head back and forth and left and right, increasing the movement range of the detection head and minimizing the problem that when adjusting the position, the sleeve can only move left and right on the guide rod, resulting in a limited adjustment range and reduced applicability.
[0009] Preferably, the lifting assembly includes an electric telescopic rod fixedly connected to the bottom end of the mounting block, and a mounting plate is fixedly connected to the bottom end of the electric telescopic rod. The detection head is mounted on the lower surface of the mounting plate.
[0010] By adopting the above technical solution, the height of the detection head can be adjusted by raising and lowering the mounting plate through the activation of the electric telescopic rod, which facilitates better detection of temperature-changing labels.
[0011] Preferably, a fixing rod is fixedly connected between the two sliders below the first threaded rod, and the mounting block is sleeved on the fixing rod to form a sliding arrangement.
[0012] By adopting the above technical solution, the mounting block can be prevented from being pressed down when the first threaded rod rotates, thus preventing the mounting block from rotating together with the first threaded rod and making it impossible to move on the first threaded rod, and facilitating the adjustment of the mounting block.
[0013] Preferably, the fixing component includes a hollow plate fixedly connected to the upper surface of the detection platform below the detection head. The upper surface of the hollow plate has a plurality of air holes communicating with the interior of the hollow plate, and an air pipe communicating with the interior of the hollow plate is fixedly connected to one side wall of the hollow plate.
[0014] By adopting the above technical solution, the air pipe is connected to an external air extraction device, and then the temperature-sensitive label is placed on the hollow plate. The air extraction component extracts air from the inside of the hollow plate, allowing the gas to enter the hollow plate through the air holes. This allows the temperature-sensitive label to be adsorbed onto the hollow plate, making it convenient to fix the temperature-sensitive label.
[0015] Preferably, the heating assembly includes two air ducts located above the testing platform on both sides of the hollow plate. An electric heating grid is installed inside the opposite end of the two air ducts, and a fan is installed inside the opposite end of the two air ducts.
[0016] By adopting the above technical solution, the air in the air duct is heated by starting the electric heating network, and then the fan is started to blow out the heated air, so that the hot air comes into contact with the temperature-sensitive label, causing the temperature-sensitive label to change color under the hot air, and then it is detected by the detection head.
[0017] Preferably, two fixing plates are fixedly connected to both sides of the inner sidewall of the testing platform, and a bidirectional screw is rotatably connected between the two fixing plates. Two locking plates are threaded onto the two bidirectional screws. Rotating rods are fixedly connected to both sides of the air duct, and the end of the rotating rod away from the air duct passes through the locking plate and is rotatably connected to the fixing plate.
[0018] By adopting the above technical solution, the locking plates are moved away from each other by rotating the bidirectional screw, and then the air duct is swung by rotating the rod to adjust the angle of the air duct, so that the hot air can be blown better onto the temperature-changing label. Then, the bidirectional screw is rotated in the opposite direction to bring the two locking plates closer together and abut against the air duct to clamp and fix the air duct, preventing the air duct from swaying during use. At the same time, the locking plates are sleeved on the rotating rod to prevent the locking plates from rotating together with the bidirectional screw.
[0019] In summary, this application includes at least one of the following beneficial technical effects:
[0020] 1. This application utilizes the cooperative arrangement of structures such as the return frame, the first threaded rod, and the second threaded rod. During use, by rotating the first threaded rod, the mounting block moves left and right on the first threaded rod. At the same time, rotating the second threaded rod causes the slider to move back and forth in the through groove, thereby enabling the mounting block to move the detection head back and forth and left and right. This increases the movement range of the detection head and avoids the problem that when adjusting the position, the sleeve can only move left and right on the guide rod, which limits the adjustment range and reduces applicability.
[0021] 2. By connecting the air tube to an external air extraction device, and then placing the temperature-sensitive label on the hollow board, the air extraction assembly extracts air from the inside of the hollow board, allowing the gas to enter the hollow board through the air holes. This allows the temperature-sensitive label to adhere to the hollow board, making it easy to fix the temperature-sensitive label. Attached Figure Description

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0028] This application discloses a temperature-changing label detection device.
[0029] Reference Figure 1 , Figure 2 and Figure 3 A temperature-sensitive label detection device includes a detection platform 1 and a detection head 2. The detection platform 1 is provided with a fixing component for placing temperature-sensitive labels, a heating component for heating temperature-sensitive labels, and a moving component for adjusting the position of the detection head 2. The moving component includes a U-shaped frame 3, a through groove 4, a slider 5, a first threaded rod 6, a mounting block 7, and a second threaded rod 8.
[0030] The U-shaped frame 3 is fixedly connected to the top of the detection table 1. Two through slots 4 are provided, which are respectively opened on the two side walls of the U-shaped frame 3. Two sliders 5 are provided, which are slidably set in the through slots 4. The first threaded rod 6 is set between the two sliders 5 and both ends pass through the sliders 5 to form a rotatable connection. The mounting block 7 is threadedly connected to the first threaded rod 6. The mounting block 7 is provided with a lifting component. The detection head 2 is mounted on the lifting component. The second threaded rod 8 is set in one of the through slots 4 and both ends pass through the through slot 4 to form a rotatable connection. The slider 5 is threadedly connected to the second threaded rod 8. One end of the first threaded rod 6 and the second threaded rod 8 are fixedly connected to a first turntable for easy rotation.
[0031] Reference Figure 1 and Figure 2 The lifting assembly includes an electric telescopic rod 9 fixedly connected to the bottom of the mounting block 7. The bottom of the electric telescopic rod 9 is fixedly connected to a mounting plate 10. The detection head 2 is installed on the lower surface of the mounting plate 10. By starting the electric telescopic rod 9, the mounting plate 10 can be raised and lowered, which can adjust the height of the detection head 2, making it easier for the detection head 2 to better detect temperature-changing labels.
[0032] Reference Figure 1 and Figure 2A fixing rod 11 is fixedly connected between the two sliders 5 and below the first threaded rod 6. The mounting block 7 is sleeved on the fixing rod 11 and forms a sliding setting. The fixing rod 11 can prevent the mounting block 7 from being pressed down when the first threaded rod 6 rotates, thus preventing the mounting block 7 from rotating together with the first threaded rod 6 and making it impossible to move on the first threaded rod 6, which facilitates the adjustment of the mounting block 7.
[0033] Reference Figure 1 , Figure 2 and Figure 4 The fixing component includes a hollow plate 12 fixedly connected to the upper surface of the detection table 1 below the detection head 2. The upper surface of the hollow plate 12 has multiple air holes 13 that communicate with the interior of the hollow plate 12. An air pipe 14 that communicates with the interior of the hollow plate 12 is fixedly connected to one side wall of the hollow plate 12. By connecting the air pipe 14 to an external air extraction device, and then placing the temperature-changing label on the hollow plate 12, the air extraction component extracts air from the interior of the hollow plate 12, allowing the gas to enter the hollow plate 12 through the air holes 13, which can cause the temperature-changing label to adhere to the hollow plate 12, making it convenient to fix the temperature-changing label.
[0034] Reference Figure 1 and Figure 3 The heating assembly includes two air ducts 15 located on both sides of the hollow plate 12 above the detection platform 1. An electric heating mesh 16 is installed inside the opposite end of the two air ducts 15, and a fan 17 is installed inside the opposite end of the two air ducts 15. The air inside the air ducts 15 is heated by starting the electric heating mesh 16, and then the fan 17 is started to blow out the heated air, so that the hot air comes into contact with the temperature-sensitive label, causing the temperature-sensitive label to change color under the hot air, and then it is detected by the detection head 2.
[0035] Reference Figure 1 and Figure 4 The testing table 1 has two fixed plates 18 fixedly connected to both sides of its interior sidewalls. A double-ended screw 19 is rotatably connected between the two fixed plates 18. One end of the double-ended screw 19 passes through the fixed plate 18 and is fixedly connected to a second turntable, facilitating rotation of the double-ended screw 19. Two locking plates 20 are threaded onto the two double-ended screws 19. Rotating rods 21 are fixedly connected to both sides of the air duct 15. The ends of the rotating rods 21 away from the air duct 15 pass through the locking plates 20 and are rotatably connected to the fixed plates 18. Rotate the bidirectional screw 19 to move the locking plates 20 away from each other. Then, rotate the rod 21 to swing the air duct 15 and adjust its angle to better direct the hot air toward the temperature-sensitive label. Then, rotate the bidirectional screw 19 in the opposite direction to move the two locking plates 20 closer together and abut against the air duct 15 to clamp and fix it in place, preventing the air duct 15 from swinging during use. At the same time, the locking plates 20 are fitted onto the rotating rod 21 to prevent the locking plates 20 from rotating together with the bidirectional screw 19.
[0036] The implementation principle of the temperature-sensitive label detection device in this application embodiment is as follows: In use, firstly, the air pipe 14 is connected to the external air extraction device, then the temperature-sensitive label is placed on the hollow plate 12, and the air extraction assembly extracts air from the inside of the hollow plate 12, allowing the gas to enter the hollow plate 12 through the air hole 13, adsorbing the temperature-sensitive label onto the hollow plate 12 and fixing the temperature-sensitive label. Then, by rotating the first threaded rod 6, the mounting block 7 moves left and right on the first threaded rod 6, while simultaneously rotating the second threaded rod 8, driving the slider 5 to move back and forth in the through groove 4, so that the mounting block 7 drives the detection head 2 to move back and forth and left and right, increasing the movement range of the detection head 2. Then, the air in the air pipe 15 is heated by starting the electric heating grid 16, and then the fan 17 is started to blow out the heated air, so that the hot air comes into contact with the temperature-sensitive label, causing the temperature-sensitive label to change color under the hot air, and then the detection head 2 is used for detection. This method avoids the problem that when adjusting the position, the sleeve can only move left and right on the guide rod, which limits the adjustment range and reduces the applicability.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
