Detailed Implementation

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figure 1 and Figure 2As shown, the non-powered roller brush cleaner provided in Embodiment 1 includes a connecting seat 1 installed on the roller bracket, a roller brush 2 rotatably installed on the connecting seat 1, the roller brush 2 is used to clean the tape, and a first transmission component 3 is provided between the roller brush 2 shaft and the roller shaft, the first transmission component 3 can drive the roller brush 2 to rotate.

[0023] In a relatively specific embodiment, the first transmission component 3 is a chain drive component, and the two sprockets of the chain drive component are respectively mounted on the idler roller shaft and the roller brush 2 shaft, and the chain of the chain drive component connects the two sprockets.

[0024] In another relatively specific embodiment, the first transmission component 3 is a pulley assembly, with two pulleys of the pulley assembly respectively rod-shaped on the roller shaft and the brush 2 shaft, and the belt of the pulley assembly connecting the two pulleys.

[0025] During the material conveying process, after the conveyor belt passes the bottom of the idler roller, it will pass the roller brush 2. While the idler roller drives the conveyor belt to move, it drives the roller brush 2 to rotate through the first transmission component 3. Thus, the roller brush 2 cleans the attached materials on the working surface of the conveyor belt in real time, extending the service life of the conveyor belt, roller and idler roller, and reducing the possibility of the conveyor belt running off track.

[0026] like Figures 3 to 8 As shown in Embodiment 2, the non-powered roller brush cleaner of this application further includes a support 4 mounted on the idler roller bracket. A scraper 5 is rotatably mounted on the support 4. The scraper 5 is located behind the roller brush 2 and is used to scrape off impurities solidified on the surface of the conveyor belt. A second transmission assembly 6 is connected between the scraper 5 shaft and the idler roller shaft, and the second transmission assembly 6 can drive the scraper 5 to rotate. By setting the scraper 5, after the conveyor belt working surface passes the roller brush 2, the cover plate can scrape off the solidified material remaining on the conveyor belt working surface in real time, improving the cleaning effect of the conveyor belt.

[0027] In this embodiment, a second transmission assembly 6 is provided between the scraper 5 shaft and the idler roller shaft. The second transmission assembly 6 can drive the scraper 5 to rotate, and when the scraper 5 rotates, it can pass through the roller brush 2 and be cleaned by the roller brush 2. Specifically, the second transmission component is set as a pulley assembly. With this arrangement, the cleaning effect of the scraper 5 on the conveyor belt can be improved by using the roller brush 2 to clean the scraper 5.

[0028] In this embodiment, a support shaft 7 is rotatably mounted on the support 4. Two scrapers 5 are provided, and both scrapers 5 are rotatably mounted on the support shaft 7. A rotating plate 8 is fixedly provided at the end of the support shaft 7, which is used to drive the two scrapers 5 to alternately scrape the working surface of the tape. By setting two scrapers 5 to alternately scrape the tape, at any given time, one scraper 5 is always scraping the tape, thereby ensuring the tape cleaning effect while both scrapers 5 are cleaned by passing through the roller brush 2 respectively.

[0029] More specifically, a sliding rod 9 is slidably provided at the end of the scraper 5, and an annular groove 10 for sliding the sliding rod 9 is provided on the support 4. A locking groove 11 is provided at the top of the arc groove. When the sliding rod 9 is located in the locking groove 11, the scraper 5 is fixed in a vertical state and scrapes the tape. A lifting groove 12 is provided on the rear side of the locking groove 11, and the bottom end of the lifting groove 12 is connected to the annular groove 10. A pushing groove is provided on the rotating plate 8. The sliding rod 9 is located in the pushing groove. During the process of the pushing groove passing through the lifting groove 12 and the locking groove 11, the sliding rod 9 located in the pushing groove enters the locking groove 11 from the lifting groove 12, and the sliding rod 9 located in the locking groove 11 falls into the pushing groove.

[0030] The scraper 5 for scraping the tape is vertical, and the sliding rod 9 on the scraper 5 is located in the locking groove 11. The sliding rod 9 is located on the outermost circumferential surface of the rotating plate 8. Another sliding rod 9 is located in the pushing groove. The pushing groove pushes the sliding rod 9 to move within the annular groove 10, causing the other scraper 5 to rotate. When the sliding rod 9 moves within the annular groove 10 and enters below the lifting groove 12, the pushing groove pushes the sliding rod 9 upward, causing the sliding rod 9 to enter the lifting groove 12 from the annular groove 10. Subsequently, as the rotating plate 8 continues to rotate, the front end of the pushing groove moves to below the locking groove 11. The sliding rod 9 located in the locking groove 11 falls into the pushing groove and, as it rotates with the pushing plate, drives the scraper 5 that was originally scraping the tape to rotate. The sliding rod 9 located in the lifting groove 12 is pushed to below the locking groove 11 and, with the cooperation of the front sidewall of the pushing groove and the locking groove 11, is pushed upward into the locking groove 11, thereby realizing that the two scrapers 5 alternately scrape the tape.

[0031] Furthermore, the pushing groove includes an outer groove 13 and an inner groove 14. The outer groove 13 has a fan-shaped structure, and the inner groove 14 is located at the front end of the inner bottom wall of the outer groove 13. The rear side walls of both the outer groove 13 and the inner groove 14 are inclined. The top of the inner cavity of the annular groove 10 is provided with a stop block 15 that is fixedly connected to the support 4. When the slide rod 9 passes the stop block 15, it is pushed up by the rear wall of the inner groove 14 into the lifting groove 12 and supported by the inner bottom wall of the outer groove 13. The rear side wall of the outer groove 13 can push the slide rod 9 below the locking groove 11 and then push the slide rod 9 up into the locking groove 11. When the rear side wall of the outer groove 13 contacts the slide rod 9, the slide rod 9 in the locking groove 11 falls into the inner groove 14.

[0032] When the slide rod 9 is in the inner groove 14, it is also in the annular groove 10. When the rotating plate 8 rotates, the inner groove 14 pushes the slide rod 9 to make a circular motion, thereby realizing the circular motion of the scraper 5. When the front side of the slide rod 9 contacts the stop block 15, it can no longer rotate forward. At this time, the inner rear side wall can push the slide rod 9 upward, and the slide rod 9 moves upward along the stop block 15 and enters the lifting groove 12. When the slide rod 9 passes the top of the rear side wall of the inner groove 14, it enters the outer groove 13. When the inner groove 14 moves from the bottom of the lifting groove 12 to directly below the locking groove 11, the slide rod 9 moves in the outer groove 13. After the sliding rod 9 in the locking groove 11 falls into the inner groove 14, the rotating plate 8 continues to rotate. The inner groove 14 pushes the sliding rod 9 inside, causing the scraper 5 that was originally scraping the tape to rotate. Meanwhile, the rear wall of the outer groove 13 pushes the sliding rod 9, which is located in the lifting groove 12, forward to the bottom of the locking groove 11. After the sliding rod 9 contacts the front wall of the locking groove 11, the rear wall of the outer groove 13 pushes the sliding rod 9 upward into the locking groove 11. The sliding rod 9 then moves through the rear wall of the outer groove 13 to the circumferential surface of the rotating plate 8 and is supported by the rotating plate 8. Thus, after the above settings are made, the alternating action of the two scrapers 5 can be automatically realized.

[0033] Furthermore, when the two slide bars 9 are respectively located in the locking groove 11 and the lifting groove 12, the two scrapers 5 are symmetrically distributed on both sides of the support shaft 7 and are flush. This arrangement ensures that before the scraper 5 currently scraping the tape detaches from the tape, the other scraper 5 switches to the tape-scraping state. This prevents any unscraped areas from existing on the tape during the alternation of the two scrapers 5, achieving omnidirectional scraping of the tape.

[0034] The bottom end of the scraper 5 is rotatably connected to a bushing 16, which is rotatably mounted on the support shaft 7. The scraper 5 can swing relative to the bushing 16, so that when the two slide rods 9 are respectively located in the locking groove 11 and the lifting groove 12, the two scrapers 5 are in a flush state.

[0035] In this embodiment, the lifting grooves 12 are arranged longitudinally. When the slide rod 9 moves from inside the lifting groove 12 to directly below the locking groove 11, the slide rod 9 moves forward in a horizontal motion.

[0036] In this embodiment, a mounting plate 17 is provided at the bottom of the scraper 5. The bottom end of the mounting plate 17 is rotatably engaged with the bushing 16, and the bottom of the scraper 5 is slidably engaged with the mounting plate 17. A spring 18 is provided inside the mounting plate 17 to support the bottom of the scraper 5. By providing the spring 18, the scraper 5 has an up-and-down buffering effect when scraping the tape, thereby effectively relieving the rigid contact between the scraper 5 and the tape and preventing the scraper 5 from damaging the tape.

[0037] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
