Description

Technical Field

[0001] The utility model relates to the technical field of scraping and washing devices, in particular to a belt scraping and washing device for a belt conveyor. Background Art

[0002] Belt scraping and cleaning devices for belt conveyors are specially designed to clean materials, dirt or impurities attached to belt conveyor belts. There are many types of scraping and cleaning devices, including scraper-type scraping and cleaning devices: similar to the working principle of a scraper, the material attached to the belt is scraped off through direct contact between the scraper and the belt. This device has a simple structure and is suitable for removing harder material residues; rotating brush-type scraping and cleaning devices: using the slight contact between the rotating brush roller and the belt surface, the material or dirt attached to the belt is removed through the brushing action of the rotating bristles. This device is suitable for removing sticky materials or fine particles.

[0003] Among them, the rotating brush scraping and cleaning device generally has a group of cleaning rollers, but the cleaning times are few, resulting in unsatisfactory cleaning effect, or two groups of cleaning rollers rotating in the same direction are set. However, during the cleaning process, the cleaning rollers rotating in the same direction may evenly spread the stains or adhesions on the belt instead of completely removing them, resulting in poor cleaning effect and low cleaning efficiency. For this reason, we propose a belt scraping and cleaning device for a belt conveyor. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model drives the first cleaning roller and the second cleaning roller to rotate in opposite directions through the first driving component to clean the first belt. Compared with the prior art, the double-brush design that rotates in opposite directions means that the two brushes work at the same time, and each brush scrubs the first belt respectively, which is equivalent to cleaning twice by a single roller brush machine, thereby doubling the cleaning ability. The two brushes rotate in opposite directions to form an inward-rolling wiping effect, which can more comprehensively cover the tiny convex and concave parts of the belt to ensure cleaning without dead angles, and is suitable for stubborn stains. Through repeated wiping by the two brushes, stains can be removed more effectively, the cleaning effect is improved, the time required for cleaning is reduced, and the cleaning efficiency is improved.

[0014] The utility model utilizes an elastic member to pull the scraper to always fit the first belt. As the first belt rotates, the scraper is used to scrape off impurities. Since the length of the scraper body is less than the length of its shaft rod, one end of the scraper shaft rod can be separated from the frame by sliding toward one side of the frame, and vice versa. In order to limit the scraper, limiting bolts are threadedly connected at both ends of the scraper shaft rod so that the scraper can no longer move, and the installation of the scraper can be completed. The scraper is easy to disassemble and replace. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In this embodiment, the driving roller 2 can be connected to a driving member such as a motor in the prior art to achieve rotation, thereby driving the first belt 3 to rotate and transporting materials. The limiting roller 4 is located below the first belt 3, and lifts the first belt 3 to present an inclined state, so as to tension the first belt 3 and facilitate the falling of impurities cleaned by the third cleaning roller 7. The first cleaning roller 5 and the second cleaning roller 6 are driven by the first driving component to rotate in opposite directions to clean the first belt 3. Compared with the prior art, the double-brush design that rotates in opposite directions means that two brushes work at the same time, and each brush scrubs the first belt 3 separately, which is equivalent to cleaning twice by a single roller brush machine, thereby doubling the cleaning capacity. The two brushes rotate in opposite directions to form an inward-rolling wiping effect, which can more comprehensively cover the tiny convex and concave parts of the belt to ensure that there are no dead angles in cleaning, and is suitable for stubborn stains. Through repeated wiping by the two brushes, stains can be removed more effectively, the cleaning effect is improved, the time required for cleaning is reduced, and the cleaning efficiency is improved. At the same time, the third cleaning roller 7 is driven by the second driving component to rotate and clean again, further improving the cleaning effect.

[0024] Please refer to Figure 1-5 As shown, the first driving assembly includes a motor 8, a first gear 9 and a second gear 10. One end of the first cleaning roller 5 close to the end of the frame 1 is connected to the output end of the motor 8, and the other end thereof is installed with the first gear 9. The first gear 9 is meshed with the second gear 10 installed at one end of the second cleaning roller 6. The other end of the second gear 10 is connected to the third cleaning roller 7 through the second driving assembly. The second driving assembly includes a first pulley 11, a second belt 12 and a second pulley 13. The first pulley 11 is installed at the end of the second cleaning roller 6 away from the second gear 10. The first pulley 11 is connected to the second pulley 13 through the second belt 12, and the second pulley 13 is installed at one end of the third cleaning roller 7.

[0025] In this embodiment, by starting the motor 8, the first cleaning roller 5 connected thereto is driven to rotate, which in turn drives the first gear 9 to rotate, causing the second gear 10 meshing therewith to rotate, driving the second cleaning roller 6 to rotate, and at the same time driving the first pulley 11 to rotate, and through the transmission of the second belt 12, driving the second pulley 13 to rotate, thereby causing the third cleaning roller 7 to rotate, and further cleaning the first belt 3.

Two sets of slide grooves 16 are symmetrically provided at one end of the frame 1, and the elastic member 15 is installed in the inner cavity of the slide groove 16. One end of the elastic member 15 is connected to the shaft of the scraper 14. The length of the scraper 14 body is less than the length of its shaft, and both ends of the shaft of the scraper 14 are threadedly connected with limit bolts 17.

[0027] In this embodiment, the scraper 14 can be pulled by an elastic member to always fit the first belt 3. As the first belt 3 rotates, the scraper 14 is used to scrape off impurities. Since the length of the scraper 14 body is less than the length of its shaft, one end of the scraper 14 shaft can be detached from the frame 1 by sliding to one side of the frame 1, and vice versa. In order to limit the scraper 14, limiting bolts 17 are threadedly connected at both ends of the scraper 14 shaft to prevent the scraper 17 from moving any further, thereby completing the installation of the scraper 14. The scraper 14 is easy to disassemble and replace.

[0028] Working principle: First, the elastic member can be used to pull the scraper 14 to always fit the first belt 3. As the first belt 3 rotates, the scraper 14 is used to scrape off impurities. Since the length of the scraper 14 body is less than the length of its shaft, one end of the scraper 14 shaft can be disengaged from the frame 1 by sliding to one side of the frame 1, and vice versa. In order to limit the scraper 14, limit bolts 17 are threadedly connected at both ends of the scraper 14 shaft so that the scraper 17 can no longer move, and the installation of the scraper 14 is completed. It is easy to disassemble and replace. By starting the motor 8, the first cleaning roller 5 connected thereto is driven to rotate, the first gear 9 is driven to rotate, the second gear 10 meshing therewith is driven to rotate, and the second cleaning roller 6 is driven to rotate, and at the same time, the first pulley 11 is driven to rotate, and the second belt 12 is driven to rotate the second pulley 13, so that the third cleaning roller 7 is rotated, and the first belt 3 is further cleaned.
