Description

Technical Field

[0001] This utility model relates to the field of ink fading detection technology, specifically to a device for detecting ink fading. Background Technology

[0002] In the field of ink performance quality assessment, accelerated fading detection is one of the key testing methods, which typically involves heating cigarette pack paper to simulate aging. However, existing heating devices have revealed significant shortcomings in long-term use. During the fading detection of cigarette pack ink, prolonged use at high temperatures can cause the ink, coatings, or adhesives on the cigarette paper to melt, carbonize, or volatilize. These residues inevitably adhere to the working surface of the heating plate. Over time, these residues accumulate, affecting not only the flatness of the heating surface and causing uneven contact with the cigarette paper, but also creating thermal resistance, reducing heat transfer efficiency, and ultimately severely impacting the accuracy of the test results. Furthermore, prolonged high-temperature operation can lead to aging of the heating elements, decreased temperature control accuracy, or mechanical deformation. However, existing heating modules are mostly fixed installations, requiring disassembly of the entire device for cleaning, which is inconvenient. Replacement procedures in case of damage are cumbersome, requiring specialized tools and technicians, resulting in long downtime and severely limiting testing efficiency. Utility Model Content

Detailed Implementation

[0019] The following detailed description illustrates the specific implementation method: Reference Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model discloses a device for detecting ink fading, comprising a base 1, a first heating plate 2 disposed on the base 1, a lifting mechanism 3 disposed on the base 1, and a second heating plate 4 disposed at the output end of the lifting mechanism 3, which cooperates with the first heating plate 2 to heat the cigarette paper. The lifting mechanism 3 can drive the second heating plate 4 to move toward and fit against the first heating plate 2 to heat the cigarette paper. Both the base 1 and the output end of the lifting mechanism 3 are provided with connecting components 5, and the first heating plate 2 and the second heating plate 4 are detachably connected to their respective connecting components 5. The detachable connecting components 5 make the installation and removal of the first heating plate 2 and the second heating plate 4 extremely convenient. This allows workers to quickly remove the first heating plate 2 and the second heating plate 4 to remove residual stains, keeping the heating surface clean and ensuring detection accuracy. When the first heating plate 2 and the second heating plate 4 are damaged or need to be replaced, no professional tools or technicians are required, greatly reducing downtime and significantly improving detection efficiency and equipment availability.

[0020] In use, the cigarette pack paper is placed on the first heating plate 2 on the base 1. Then, the lifting mechanism 3 moves the second heating plate 4 towards the first heating plate 2 until the second heating plate 4 is in contact with the cigarette pack paper, thereby heating the cigarette pack paper to observe the ink fading on the surface of the cigarette pack paper. In this embodiment, the lifting mechanism 3 includes a bracket 31, several guide columns 32, a guide plate 33, and a cylinder 34. Specifically, the bracket 31 is fixedly installed on the base 1, the bottom ends of the several guide columns 32 are fixedly connected to the base 1, and the top ends of the several guide columns 32 are fixedly connected to the inner wall of the top end of the bracket 31. The cylinder 34 is fixedly mounted on the bracket 31, and the piston rod end of the cylinder 34 passes through the bracket 31 and is fixedly connected to the guide plate 33. The guide plate 33 has through holes 331 corresponding to a plurality of guide posts 32. The guide plate 33 passes through the guide posts 32 through the through holes 331 and can slide along the axial direction of the guide posts 32. The second heating plate 4 and the connecting assembly 5 are both located on the side of the guide plate 33 away from the cylinder 34. The cylinder 34 provides reliable linear drive power to ensure the smoothness of the lifting and lowering movement of the second heating plate 4 and sufficient clamping force. The cooperation between the guide posts 32 and the through holes 331 accurately guides the guide plate 33 and the second heating plate 4 to move in the vertical direction, preventing skewing and ensuring that the second heating plate 4 and the first heating plate 2 can be evenly and parallelly attached, thereby making the cigarette paper heat evenly and the test results more reliable.

[0021] In the process of detecting ink fading on cigarette packaging paper, the first heating plate 2 and the second heating plate 4, as core components that directly contact the cigarette paper and transfer heat, will inevitably adhere to the working surfaces of the first heating plate 2 and the second heating plate 4 after long-term use due to the high temperature heating, causing the ink, coating, or adhesive on the cigarette paper to melt, carbonize, or volatilize. Over time, the residue accumulates, not only affecting the flatness of the heating surface and causing uneven contact with the cigarette paper, but also forming thermal resistance, reducing heat conduction efficiency, and ultimately seriously affecting the accuracy, consistency, and repeatability of the test results. In addition to the above-mentioned contamination requiring regular cleaning, long-term high-temperature operation may also lead to aging of the heating elements, decreased temperature control accuracy, or mechanical deformation. To facilitate cleaning or replacement of the first heating plate 2 and the second heating plate 4, in this embodiment, a connecting plate 6 is fixedly connected to both the first heating plate 2 and the second heating plate 4, and the first heating plate 2 and the second heating plate 4 can be fixedly connected to the connecting plate by high-temperature resistant screws. The connecting plate 6 has connecting grooves 61 at both ends along its length. The connecting assembly 5 includes a housing 51, connecting blocks 52 at both ends of the housing 51 along its length, and a driving member 535 within the housing 51 for driving the two connecting blocks 52 to move in a direction that approaches or moves away from each other. When the driving member 535 drives the two connecting blocks 52 to move closer together, the two connecting blocks 52 can be inserted into the connecting grooves 61 at both ends of the connecting plate 6, and the first heating plate 2 and the second heating plate 4 are fixedly connected to their respective connecting assemblies 5. When the driving member 535 drives the two connecting blocks 52 to move away from each other, the two connecting blocks 52 can disengage from the connecting grooves 61 at both ends of the connecting plate 6, so that the first heating plate 2 and the second heating plate 4 are disengaged from their respective connecting assemblies 5. Through the plug-in structure of the connecting plate 6 and the connecting assembly 5, a quick and reliable snap-fit ​​installation of the first heating plate 2 and the second heating plate 4 is achieved.

[0022] Specifically, in this embodiment, the drive assembly 53 includes two sets of springs 531, two vertical plates 532, two transmission rods 533, two limiting plates 534, and a drive component 535. The housing 51 has a receiving cavity 511 extending along its length. The two limiting plates 534 are symmetrically and spaced apart within the receiving cavity 511 along the length of the housing 51, so that the receiving cavity 511 forms a first mounting cavity 5111, a second mounting cavity 5112, and a third mounting cavity 5113 along its length. The first mounting cavity 5111 and the third mounting cavity 5113 are symmetrical to the second mounting cavity 5112. Two sets of springs 531, two sets of vertical plates 532, and two sets of transmission rods 533 are respectively disposed in the first mounting cavity 5111 and the third mounting cavity 5113. The two sets of vertical plates 532 abut against the opposite sides of the two limiting plates 534. The two ends of the two sets of springs 531 abut against the two sets of vertical plates 532 and the end walls of the first mounting cavity 5111 and the third mounting cavity 5113 away from the second mounting cavity 5112. The two transmission rods 533, with their ends facing away from each other, pass through the end walls of the first mounting cavity 5111 and the third mounting cavity 5113, respectively, away from the second mounting cavity 5112, and are then fixedly connected to the connecting blocks 52 at both ends of the housing 51. The two transmission rods 533, with their ends facing towards each other, are fixedly connected to the two vertical plates 532, and then extend through the two limiting plates 534 into the second mounting cavity 5112. The driving member 535 is located in the second mounting cavity 5112 and between the two ends facing towards each other, and is used to drive the two transmission rods 533 to move in opposite directions along the length of the housing 51 against the elastic force of the two sets of springs 531. When the driving member 535 is not operated, the two sets of springs 531 are in a naturally extended or slightly compressed state. Since the two ends of the two sets of springs 531 respectively abut against the end walls of the corresponding vertical plates 532 and the first mounting cavity 5111 and the third mounting cavity 5113, the elastic force of the two sets of springs 531 will push the two vertical plates 532 to move closer to the second mounting cavity 5112. At this time, the two transmission rods 533 fixedly connected to the vertical plates 532 will move synchronously with the two vertical plates 532. The ends of the two transmission rods 533 that are close to each other in the second mounting cavity 5112, while the ends that are far apart drive the connecting blocks 52 at both ends of the housing 51 to move closer to each other. Finally, the two connecting blocks 52 are respectively inserted into the connecting grooves 61 at both ends of the connecting plate 6, thereby fixing the first heating plate 2 or the second heating plate 4 to the corresponding connecting assembly 5.

[0023] When the heating plate needs to be disassembled, the driving member 535 applies a force to the adjacent ends of the two transmission rods 533. The driving member 535 pushes the two transmission rods 533 within the second mounting cavity 5112, forcing them to overcome the elastic force of the two sets of springs 531 and move them away from each other along the length of the housing 51. At this time, the two transmission rods 533 will drive the vertical plates 532 fixed to them to move synchronously, and the two vertical plates 532 will compress their corresponding springs 531. Simultaneously, the distant ends of the two transmission rods 533 drive the connecting blocks 52 at both ends of the housing 51 to move away from each other, gradually disengaging from the connecting grooves 61 at both ends of the connecting plate 6. Once the connecting blocks 52 are completely disengaged from the connecting grooves 61, the first heating plate 2 or the second heating plate 4 can be separated from the corresponding connecting assembly 5, achieving disassembly. Through the above operations, the drive assembly 53, with the help of the elastic force of the spring 531 and the external force of the drive member 535, realizes the insertion or disengagement of the connecting block 52, thereby completing the quick assembly and disassembly of the first heating plate 2 or the second heating plate 4 with the corresponding connecting assembly 5. To ensure the accuracy and stability of the connection, the surface of the connecting plate 6 is provided with a plurality of positioning blocks 62, and the surface of the housing 51 is provided with a plurality of positioning grooves 512 that are adapted to the positioning blocks 62. The plurality of positioning blocks 62 can be inserted into the plurality of positioning grooves 512. The connecting plate 6 is a connecting component fixed on the first heating plate 2 and the second heating plate 4. When installing the first heating plate 2 or the second heating plate 4, the plurality of positioning blocks 62 on the connecting plate 6 must first be aligned and inserted into the plurality of positioning grooves 512 on the housing 51 to form an insertion fit. At this time, the relative movement of the connecting plate 6 and the housing 51 in the plane is restricted, and then the connecting block 52 of the connecting assembly 5 is inserted into the connecting groove 61 of the connecting plate 6 to complete the final fixation. This design ensures the precision of the installation position. The rigid fit between the positioning block 62 and the positioning groove 512 precisely limits the installation position of the first heating plate 2 and the second heating plate 4, ensuring that they are completely aligned when heating is closed, and avoiding uneven heating of the cigarette paper due to installation misalignment. Furthermore, the fit between the positioning block 62 and the positioning groove complements the fixing function of the connecting block 52 and the connecting groove 61, further resisting relative displacement caused by vibration or external forces during equipment operation, ensuring a stable and reliable heating process.

[0024] To drive the two connecting blocks 52 to move, in this embodiment, the driving component 535 includes a push block 5351 and an operating lever 5352. The push block 5351 is disposed in the second mounting cavity 5112 and located between the close ends of the two transmission rods 533. The push block 5351 has symmetrical inclined surfaces 53511 at both ends along its length. The inclined surfaces 53511 are based on the centerline of the width direction of the push block 5351 and gradually tilt away from the centerline of the push block 5351 from the middle to both ends. The two ends of the push block 5351 can fit tightly against the close ends of the two transmission rods 533. When the push block 5351 moves, its two ends abut against the two transmission rods 533 via inclined surfaces 53511, driving them to move in opposite directions along the length of the housing 51. One end of the operating rod 5352 is fixedly connected to one end of the push block 5351 along its width, and the other end of the operating rod 5352 slides along the width of the housing 51 through the side wall of the housing 51. The inclined surfaces 53511 of the push block 5351 convert the lateral force of the operating rod 5352 into the longitudinal force of the transmission rod 533. Utilizing the principle of force-saving on inclined surfaces, the external force required to drive the transmission rods 533 is reduced, making the disassembly of the first heating plate 2 or the second heating plate 4 easier. The symmetrical structure of the push block 5351 ensures that the two transmission rods 533 move synchronously to both ends, avoiding jamming or uneven force caused by the connection block 52 on one side disengaging first, thus improving the smoothness of disassembly. Furthermore, the detachment and repositioning of the connecting block 52 can be controlled by pushing and pulling the operating lever 5352 laterally, eliminating the need to operate the transmission rods on both sides separately, thus reducing operational complexity. In this embodiment, to facilitate operation, a handle 53521 is fixedly connected to one end of the operating lever 5352 that penetrates the side wall of the housing 51. The handle 53521 provides a more comfortable grip point, preventing hand slippage when directly pulling the operating lever 5352, which is especially suitable for scenarios involving frequent disassembly of the first heating plate 2 or the second heating plate 4, reducing operational fatigue. Since the handle 53521 is larger than the operating lever 5352, the position of the operating lever 5352 can be intuitively determined visually and tactilely.

[0025] To ensure the accuracy and stability of the movement of the push block 5351, a groove 5341 extending along the moving direction of the push block 5351 is provided on each of the two limiting plates 534 on opposite sides. Both ends of the push block 5351 are respectively embedded in the grooves 5341 of the two limiting plates 534, allowing the push block 5351 to slide along the length of the groove 5341. The groove 5341 provides radial constraint to the push block 5351, preventing it from wobbling up and down or veering left and right during sliding, and ensuring a stable fit between the push block 5351 and the transmission rod 533. This constraint ensures that the inclined surfaces 53511 at both ends of the push block 5351 are always precisely engaged with the ends of the two transmission rods 533 that are close to each other, ensuring that the two transmission rods 533 are subjected to uniform force and move synchronously along the length of the housing 51, avoiding drive jamming or unilateral transmission failure caused by the offset of the push block 5351, and ensuring that the locking or unlocking action of the connecting assembly 5 on the first heating plate 2 and the second heating plate 4 is reliable and effective.

[0026] To reduce the friction between the two transmission rods 533 and the push block 5351, a mounting bracket 7 is fixedly connected to the adjacent ends of each of the two transmission rods 533. Each mounting bracket 7 contains a roller 71 rotatably connected via a pivot. The outer circumferential surface of the roller 71 protrudes from the mounting bracket 7, and the outer circumferential surface of the roller 71 can tightly fit against the inclined surfaces 53511 at both ends of the push block 5351 along the length of the housing, allowing the roller 71 to roll along the inclined surfaces 53511. The roller 71 converts the sliding friction between the transmission rods 533 and the push block 5351 into rolling friction, significantly reducing wear at the contact points and extending the service life of the drive component 535. Since the resistance of rolling friction is much less than that of sliding friction, the process of the push block 5351 driving the transmission rods 533 can be smoother, avoiding jamming or difficult operation due to excessive friction. Furthermore, the line contact between the roller 71 and the inclined surface 53511 is more stable, which can ensure that the pushing force of the push block is evenly transmitted to the transmission rod 533, avoid unilateral force deviation caused by uneven sliding friction, and ensure that the connecting blocks 52 on both sides move synchronously.

[0027] The working principle of this utility model for a device used to detect ink fading is as follows: In use, cigarette pack paper is placed on the surface of the first heating plate on the base. The cylinder fixed to the bracket in the lifting mechanism is activated, and its piston rod pushes the guide plate vertically downwards along the axial direction of several guide columns. This causes the second heating plate below the guide plate to move closer to the first heating plate and adhere to the cigarette pack paper, achieving controlled heating of the cigarette pack paper to simulate aging. When residual stains accumulate on the surface of the first or second heating plate and need cleaning, or when components are damaged and need replacement, pulling the handle moves the operating rod and the push block along the width direction of the housing. The inclined surfaces at both ends of the push block push the rollers at the ends of the two transmission rods, causing the transmission rods to drive the vertical plate to compress the spring and move towards both ends of the housing. This, in turn, causes the connecting block to disengage from the connecting groove of the connecting plate, allowing the heating plate to be removed. During reinstallation, align the positioning block of the connecting plate with the positioning groove of the housing and insert it for positioning. Release the handle, and the spring will reset, pushing the vertical plate against the limiting plate. The connecting block will then be reinserted into the connecting groove to complete the fixing and resume the testing operation.

[0028] This utility model discloses a device for detecting ink fading, which has the following advantages: Through a detachable structure composed of the connecting plate and the connecting assembly, combined with the precise positioning of the positioning block and the positioning groove, tool-free quick assembly and disassembly of the first and second heating plates are achieved. This solves the problem of inconvenient cleaning of residual stains on the heating plate surface and avoids the drawbacks of cumbersome replacement procedures and long equipment downtime caused by traditional fixed installations, significantly improving detection efficiency. Simultaneously, the cooperation between the guide column and the guide plate in the lifting mechanism ensures the parallelism of the heating plates when they are in contact, guaranteeing uniform heating of the cigarette paper. Combined with the low-friction design of the roller and the inclined surface in the drive assembly, and the stable reset function of the spring, the detection accuracy, ease of operation, and long-term reliability of the device are further improved, overcoming the shortcomings of traditional equipment.

[0029] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
