Description

An online blanket detection device Technical Field

[0001] This utility model relates to the technical field of blanket detection devices, and in particular to an online blanket detection device. Background Technology

[0002] In the high-speed toilet paper production process, the felt is a key component, and its condition directly affects the quality of toilet paper, production efficiency, and equipment lifespan. Therefore, a testing device is needed to inspect the felt during production to prevent the production of defective toilet paper, maintain the appearance quality of the product, ensure that the physical properties of the toilet paper always meet the standards, improve product consistency, help stabilize the quality of the toilet paper's fluff, and guarantee its performance.

[0003] Existing detection devices mainly rely on manual inspection by operators. Manual inspection is mostly performed at set or irregular intervals, making real-time monitoring impossible. During these intervals, the moisture content of the blankets may change without being detected in time, leading to delays in adjusting process parameters and impacting product quality and production efficiency. Furthermore, manual inspection depends on the operator's skills and experience; differences in operating techniques and instrument usage among different personnel can easily introduce measurement errors. Moreover, manual inspection typically only obtains moisture data from localized areas of the blanket, failing to comprehensively reflect the overall moisture distribution. This increases the workload of operators, especially after prolonged work, leading to fatigue, potentially resulting in reduced inspection frequency, inaccurate results, or even safety hazards such as instruments falling into the machine. Additionally, manual inspection data cannot be directly fed back to the tissue paper machine's control system, hindering the automatic adjustment of relevant process parameters based on blanket moisture content and impeding improvements in automation and intelligence within the production process.

[0004] Therefore, in view of the problem that the above-mentioned detection devices mainly rely on manual detection by operators, which affects product quality and production efficiency, makes it difficult to automatically adjust relevant process parameters according to the moisture content of the blanket, and is not conducive to improving the automation and intelligence level of the production process, an online blanket detection device can be designed. Summary of the Invention

[0005] To overcome the problems that the detection device mainly relies on manual inspection by operators, which affects product quality and production efficiency, and makes it difficult to automatically adjust relevant process parameters according to the moisture content of the blanket, thus hindering the improvement of the automation and intelligence level of the production process, an online blanket detection device is proposed.

[0006] The technical solution of this utility model is as follows: an online blanket detection device, including a crossbeam; a detection component for blanket detection is installed on the crossbeam, and mounting components for fixed installation are installed on both sides of the bottom end of the crossbeam. A sliding groove is opened in the middle of the top end of the crossbeam. The detection component includes a drive motor, which is located on the right side of the crossbeam. The output end of the drive motor is connected to a lead screw, which is located inside the crossbeam. Two sets of sliders are slidably connected to the outside of the lead screw.

[0007] Preferably, a detection sensor is provided at the top of the slider, and the detection sensor is slidably connected to the surface of the crossbeam. Detection probes are rectangularly distributed at the top of the detection sensor, and the top of the detection probes is provided with a ceramic surface.

[0008] Preferably, the front end of the crossbeam is fixedly connected to a fixing lug, and a connecting rod is provided at the middle position on the opposite side of the fixing lug, and a side plate is rotatably connected to the outer side of the fixing lug connecting rod.

[0009] Preferably, support rollers are connected between the side plates, and there are two sets of support rollers rotatably connected to the front end of the crossbeam.

[0010] Preferably, the mounting assembly includes support blocks, which are disposed on the left and right sides of the bottom end of the crossbeam, and rubber pads are disposed between the support blocks and the crossbeam.

[0011] Preferably, telescopic columns are provided on the front and rear sides of the bottom of the support block, and the telescopic ends of the telescopic columns are fixedly connected to the bottom of the support block. A base plate is provided at the bottom of the telescopic column, and a fixing block is installed at the middle position of the top of the base plate.

[0012] Preferably, an electric telescopic rod is installed on one side of the fixing block, and a mounting bracket is provided on the other side of the fixing block. Two locking posts are provided on the opposite side of the mounting bracket, and a locking spring is provided between the locking spring and the locking post.

[0013] The beneficial effects of this utility model are as follows: By driving the lead screw to rotate through the drive motor, the slider moves on the crossbeam, thereby enabling the detection sensor to scan and detect the entire width of the blanket, obtaining comprehensive moisture distribution data. At the same time, the detection sensor can continuously detect the moisture content of the blanket online. The moisture content of the blanket can be measured based on the change in dielectric constant caused by different water contents in the fabric. The detection probe obtains data through contact with the fabric, and the ceramic setting ensures long-lasting measurement accuracy. Attached Figure Description

[0020] Please refer to Figures 1-5. This utility model provides an embodiment: an online blanket detection device, including a crossbeam 1; a detection component for blanket detection is installed on the crossbeam 1, and mounting components for fixed installation are installed on both sides of the bottom end of the crossbeam 1. A sliding groove 2 is provided in the middle position inside the top end of the crossbeam 1. The detection component includes a drive motor 301, which is located on the right side of the crossbeam 1. The output end of the drive motor 301 is connected to a lead screw 302, which is located inside the crossbeam 1. Two sets of sliders 303 are slidably connected to the outside of the lead screw 302.

[0021] Please refer to Figure 2. In this embodiment, a detection sensor 304 is provided at the top of the slider 303, and the detection sensor 304 is slidably connected to the surface of the crossbeam 1. Detection probes 305 are rectangularly distributed at the top of the detection sensor 304, and a ceramic surface 306 is provided at the top of the detection probes 305. A fixing ear 307 is fixedly connected to the front end of the crossbeam 1, and a connecting rod is provided at the middle position of one side of the fixing ear 307. A side plate 308 is rotatably connected to the outside of the connecting rod of the fixing ear 307. Support rollers 309 are connected between the side plates 308, and there are two sets of support rollers 309 rotatably connected to the front end of the crossbeam 1.

[0022] The detection sensor 304 slides on the surface of the crossbeam 1 via the slider 303, enabling detection across the entire width of the blanket. This, combined with the blanket's movement on the production line, allows for full-area detection, avoiding blind spots and ensuring the detection of potential problems throughout the blanket. The ceramic surface 306 at the tip of the detection probe 305 has excellent wear resistance and contact performance, allowing for better contact with the blanket surface and improved data acquisition accuracy. Simultaneously, the rectangular distribution of the detection probes 305 at the top of the detection sensor 304 allows for simultaneous data collection from multiple points, making the collected data more representative and further enhancing detection precision. Two sets of support rollers 309 are positioned at the front end of the crossbeam 1, providing support and guidance for the moving blanket. During detection, the support rollers 309 rotatably connect to the side plates 308, automatically adjusting their angle according to the blanket's movement to accommodate undulations and deviations, ensuring stable blanket operation and preventing blanket sway from affecting detection results. This also reduces friction between the blanket and the detection device, extending the blanket's lifespan.

[0023] Please refer to Figures 3-5. In this embodiment, the mounting assembly includes a support block 401, which is disposed on the left and right sides of the bottom end of the crossbeam 1. A rubber pad 402 is disposed between the support block 401 and the crossbeam 1. Telescopic columns 403 are disposed on the front and rear sides of the bottom end of the support block 401, and the telescopic ends of the telescopic columns 403 are fixedly connected to the bottom end of the support block 401. A base plate 404 is disposed at the bottom end of the telescopic column 403, and a fixing block 405 is installed at the middle position of the top of the base plate 404. An electric telescopic rod 406 is installed on one side of the fixing block 405, and a mounting bracket 407 is disposed on the other side of the fixing block 405. Two locking columns 408 are disposed on the opposite side of the mounting bracket 407, and a locking spring 409 is disposed between the locking spring 409 and the locking column 408.

[0024] The telescopic column 403 allows for flexible adjustment of the height of the crossbeam 1. On different high-speed toilet paper production lines, the height of the blanket may vary. This adjustable structure allows the detection device to adapt to various production line layouts without requiring large-scale modifications, significantly improving its versatility and adaptability. The rubber pad 402 between the support block 401 and the crossbeam 1 acts as a buffer and shock absorber. During high-speed toilet paper production, the equipment generates a certain degree of vibration, which the rubber pad 402 effectively absorbs, preventing vibration from being transmitted to the detection components and thus ensuring the stability of the detection sensor. The stable operation of precision components such as 304 stainless steel improves the accuracy of test data. The combination of the locking post 408 and the locking spring 409 enables a stable connection between the testing device and the production line installation structure. The elasticity of the locking spring 409 allows the locking post 408 to automatically adapt to the slight differences in the installation structure during the locking process, tightly locking the installation structure and preventing the testing device from shifting or shaking during production line operation, thus ensuring the continuous and stable operation of the testing work. At the same time, the electric telescopic rod 406 precisely controls the movement of the mounting bracket 407, making the locking operation more convenient and accurate, and further enhancing the reliability of the connection.

[0025] Based on the actual installation location and testing requirements of the blanket, the testing device is installed on the high-speed toilet paper machine. Bolts are used to firmly fix the base plate 404 to the mounting surface. The height of the support block 401 is adjusted via the telescopic column 403 to ensure the crossbeam 1 is at a suitable height and level. Simultaneously, the rubber pad 402 acts as a buffer and shock absorber, reducing the impact of external vibrations on the testing results. The electric telescopic rod 406 is activated, pushing the mounting bracket 407 to move, thereby adjusting the position of the locking column 408 so that it abuts against the high-speed toilet paper machine frame. Utilizing the elasticity of the locking spring 409, the locking column 408 is tightly locked into the high-speed toilet paper machine frame, thus ensuring the blanket... When the blanket is being tested, the drive motor 301 is started. The output end of the drive motor 301 drives the lead screw 302 to rotate. Since the slider 303 is slidably connected to the lead screw 302, the rotation of the lead screw 302 will cause the slider 303 to move along the axial direction of the lead screw 302. The detection sensor 304 at the top of the slider 303 will slide on the surface of the crossbeam 1 to detect different positions of the blanket. During the movement of the detection sensor 304, the rectangularly distributed detection probes 305 at its top will contact the surface of the blanket to collect the moisture content of the blanket. The ceramic surface 306 at the top of the detection probe 305 can protect the probe and improve the contact performance with the blanket surface, ensuring long-term measurement accuracy.
