Description

Technical Field

[0001] This utility model belongs to the field of papermaking equipment technology, specifically relating to a papermaking grading screen cleaning device. Background Technology

[0002] In the paper production process, the grading screen is an important piece of equipment that separates fibers and impurities of different particle sizes through the synergistic action of multiple screening components. Its operating status is directly related to the subsequent paper forming quality and production efficiency. During long-term use, fibers, fillers and other impurities in the pulp are very easy to adhere to the surface of the screening components, and some fine particles will embed inside the screen holes. If not cleaned in time, the screen holes will be blocked, the screening efficiency will decrease, and even the service life of the grading screen will be affected.

[0003] Traditional paper grading screens are mostly cleaned manually or by simple mechanical means. Operators need to use tools to clean them, which is not only labor-intensive, but also makes it difficult to completely remove stubborn stains inside the screen holes. The cleaning effect is inconsistent. Some more advanced devices use simple mechanical cleaning devices, which often use a single scraper or spray structure. These devices can only roughly clean the surface of the screening components and cannot penetrate into the screen holes for targeted cleaning, resulting in incomplete cleaning and greatly affecting screening efficiency.

[0027] Example 1

[0028] Reference Figure 1-6 This is the first embodiment of the present invention, which provides a paper grading screen cleaning device, including...

[0029] The screening mechanism 100 includes a support housing 101, a first screening component 102 disposed on the inner wall of the support housing 101, and a second screening component 103 disposed at the bottom of the first screening component 102;

[0030] The cleaning mechanism 200 includes a scraping assembly 201 disposed on one side of the support housing 101, and two cleaning assemblies 202 disposed on the outer surfaces of the first screening assembly 102 and the second screening assembly 103, respectively. The scraping assembly 201 is used to scrape off the stains on the surfaces of the first screening assembly 102 and the second screening assembly 103, and the cleaning assemblies 202 are used to remove the stains in the sieve holes.

[0031] It should be noted that the outer surface of the support shell 101 is equipped with a vibration motor and the bottom is equipped with a spring support. Together with the first screening component 102 and the second screening component 103, the material can be graded and screened.

[0032] Specifically, the scraping assembly 201 includes a servo motor 201a adapted to be installed on one side of the support housing 101, a threaded rod 201b fixedly connected to the output end of the servo motor 201a via a coupling, and a support seat 201c rotatably sleeved on the end of the threaded rod 201b, the support seat 201c being fixedly connected to the outer surface of the support housing 101.

[0033] It should be noted that the servo motor 201a has a mounting box on its outside for installation and protection, and the support base 201c is used to fix the threaded rod 201b.

[0034] Furthermore, the scraping assembly 201 also includes a threaded block 201d sleeved on the outer surface of the threaded rod 201b, an upper transmission rod 201e fixedly installed on the top of the threaded block 201d, and a lower transmission rod 201f fixedly installed on the bottom of the threaded block 201d. The inner surface of the threaded block 201d is threadedly connected to the outer surface of the threaded rod 201b.

[0035] It should be noted that the upper transmission rod 201e and the lower transmission rod 201f are used to link the various components of the cleaning mechanism 200. When the servo motor 201a drives the threaded rod 201b to rotate, it drives the threaded block 201d, which is threadedly connected to the threaded rod 201b, to move along the axial direction of the threaded rod 201b. In turn, the upper transmission rod 201e and the lower transmission rod 201f drive the remaining parts of the cleaning mechanism 200 to move.

[0036] Furthermore, the scraping assembly 201 also includes three sets of symmetrically opened grooves 201g on the outer surface of the supporting housing 101, sliding blocks 201h disposed inside the grooves 201g, and two scrapers 201i disposed between the grooves 201g. The two scrapers 201i are respectively disposed on the top of the first screening assembly 102 and the top of the second screening assembly 103, and the two ends of the scrapers 201i are respectively fixedly connected to the sliding blocks 201h.

[0037] It should be noted that the three sets of sliding grooves 201g are arranged in parallel to cooperate with the cleaning mechanism 200 to perform reciprocating cleaning motion. The sliding block 201h can slide along the sliding groove 201g without deflection. The top sliding block 201h of the device is fixedly connected to the scraper 201i, the middle sliding block 201h is fixedly connected to another scraper 201i and the cleaning component 202, and the bottom sliding block 201h is fixedly connected to another cleaning component 202. Under the action of the upper transmission rod 201e and the lower transmission rod 201f, the three sets of sliding blocks 201h can slide synchronously.

[0038] Preferably, the cleaning component 202 includes a support frame 202a fixedly connected to the inner surface of the sliding block 201h, a drive motor 202b adapted to be installed on the outer surface of the support frame 202a, and a transmission component 202c fixedly connected to the output end of the drive motor 202b via a coupling.

[0039] It should be noted that the transmission component 202c includes an input pulley, an output pulley, and a transmission belt sleeved on the outer surface of the input pulley and the output pulley. The output end of the drive motor 202b drives the input pulley to rotate, and the input pulley drives the output pulley to rotate through the transmission belt, thereby transmitting power to the next component.

[0040] The cleaning component 202 also includes a cam 202d rotatably connected to the support frame 202a, and a lifting wheel 202e that slides in contact with the inner surface of the support frame 202a. One end of the transmission component 202c is fixedly connected to the output end of the drive motor 202b, and the other end is fixedly connected to the cam 202d coaxially. The cam 202d slides in contact with the lifting wheel 202e.

[0041] It should be noted that the cam 202d is driven to rotate by the transmission component 202c, while the lifting wheel 202e always remains in contact with the cam 202d due to gravity. Therefore, when the cam 202d rotates, the lifting wheel 202e will be repeatedly lifted and lowered by the outer edge of the cam 202d.

[0042] Furthermore, the cleaning assembly 202 also includes a guide block 202f that slides in contact with the inner surface of the support frame 202a, a cleaning plate 202g disposed on the top of the guide block 202f, and a synchronous shaft 202h that is fixedly connected to both sides of the cam 202d. The lifting wheel 202e is fixedly connected to the guide block 202f, and both ends of the cleaning plate 202g are fixedly connected to the guide block 202f respectively.

[0043] It should be noted that the square design of the guide block 202f is used to prevent the cleaning plate 202g from deflecting. The top of the cleaning plate 202g is equipped with a stiff nylon brush to push out the dirt in the filter mesh holes, making it easier for the scraper 201i to scrape and clean it. The synchronous shaft 202h is used to drive the cams 202d on both sides to rotate synchronously, thereby cleaning the filter mesh holes.

[0044] In use, first reset the cleaning mechanism 200, i.e., the threaded block 201d is located at the end closest to the servo motor 201a. Start the drive motor 202b. When the drive motor 202b rotates, it drives the cam 202d to rotate through the transmission component 202c. When the cam 202d rotates, it drives the lifting wheel 202e, which is always in contact with its outer surface, to move up and down. It also drives the other cam 202d to rotate synchronously through the synchronous shaft 202h, realizing the synchronous lifting and lowering of the guide blocks 202f on both sides. Finally, it drives the cleaning plate 202g to move up and down reciprocally, and cleans the filter holes through the brush on its top. At this time, start the servo motor 201a. The servo motor 201a drives the threaded rod 201b to rotate, which drives the threaded block 201d to move along the axial direction of the threaded rod 201b, and then cooperates with the transmission rod. 201e and the lower transmission rod 201f drive three sets of sliding blocks 201h to slide synchronously in the chute 201g. The sliding of the sliding blocks 201h will drive the scraper 201i fixedly connected to them to move. The two scraper 201i slide on the top of the first screening component 102 and the second screening component 103 respectively to scrape off the dirt on their surfaces. The two sets of cleaning plates 202g first push out the dirt in the filter holes of the first screening component 102 and the second screening component 103, and then the dirt on the top of the first screening component 102 and the second screening component 103 is scraped away by the scraper 201i together with the dirt. When cleaning is completed, the drive motor 202b is turned off and the servo motor 201a is rotated in the opposite direction until the threaded block 201d returns to the end where the servo motor 201a is located, and the device returns to the initial state.

[0045] In summary, the supporting shell 101 provides a stable support and installation foundation. Through the coordinated work of the scraping assembly 201 and the cleaning assembly 202, a comprehensive cleaning of the grading screen is achieved. In the cleaning assembly 202, the drive motor 202b drives the cam 202d to rotate, causing the lifting wheel 202e to drive the guide block 202f and the cleaning plate 202g to reciprocate up and down. The nylon brush on the top of the cleaning plate 202g can penetrate into the screen holes of the first screening assembly 102 and the second screening assembly 103 to push out the dirt. Subsequently, the scraper 201i of the scraping assembly 201, driven by the sliding block 201h, scrapes away the dirt and surface residues pushed out of the screen holes on the surface of the first screening assembly 102 and the second screening assembly 103. This "push out first and then scrape" cleaning method effectively solves the problems of easy clogging of screen holes and difficulty in removing surface dirt in traditional cleaning, ensuring that the grading screen always maintains a good screening state and significantly improving the efficiency of material grading and screening.

[0046] In addition, the synchronous shaft 202h ensures the synchronous rotation of the two cams 202d, making the cleaning plate 202g rise and fall smoothly. The guide block 202f prevents the cleaning plate 202g from tilting. Before cleaning, the cleaning mechanism 200 is reset, and the drive motor 202b and servo motor 201a are started to achieve automatic cleaning. After cleaning, the servo motor 201a is rotated in the opposite direction to restore the device to its initial state. The device can be effectively cleaned without complicated manual operation, thus extending the service life of the device.
