Description

Technical Field

[0002] Belt conveyors are widely used in various industries. In the food production process, belt conveyors are needed to transport materials.

[0003] Chinese patent CN221606944U discloses a belt conveyor with a scraper structure, in which a scraper and a brush are arranged in sequence under the conveyor belt, so that when conveying some materials that will adhere to the conveyor belt, the scraper will scrape off the materials remaining on the conveyor belt. In this process, some of the scraped materials will re-stick to the contact end of the scraper and the conveyor belt. As the working time of the conveyor belt increases, the materials sticking to the contact end of the scraper will gather more and more, causing the contact end of the scraper to become blunt, so that the cleaning effect of the scraper is reduced. At the same time, when the conveyor belt passes through the brush, the bristles on the brush will always remain tilted in one direction. Over time, the bristles of the brush will fall over and lose their cleaning function. Moreover, the brush can only clean the conveyor belt from one direction and cannot clean the conveyor belt comprehensively, resulting in poor cleaning effect of the conveyor belt.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1-Figure 10 A belt conveyor with a cleaning device comprises a conveyor frame 1 and a conveyor belt 14 mounted on the conveyor frame 1. The conveyor frame 1 is provided with a scraper assembly 2, a cleaning brush mechanism 3 and a driving assembly 6. The scraper assembly 2 comprises a scraper plate 21 and a cleaning scraper blade 25. The scraper plate 21 is connected to the discharge end of the conveyor frame 1, and its scraper end abuts against the conveyor belt 14 at the lower side. After the conveyor belt 14 unloads the material from the discharge end, it moves toward the scraper plate 21. The scraper plate 21 scrapes off the residual material on the conveyor belt 14 through its scraper end. The cleaning scraper blade 25 is slidably arranged on the scraper plate 21. The cleaning brush mechanism 3 is located on one side of the scraper plate 21. The structure 3 includes a brush plate seat 31, a locking assembly 4 and a cleaning brush plate 5. Several brush plate seats 31 are installed on the conveyor frame 1 in sequence. Each brush plate seat 31 is provided with a locking assembly 4. The locking assembly 4 fixes the cleaning brush plate 5 on the brush plate seat 31. The cleaning brush plate 5 is provided with a plurality of bristles 51. The bristles 51 are in contact with the lower side of the conveyor belt 14. The driving assembly 6 cooperates with the cleaning blade 25 and the brush plate seat 31. The driving assembly 6 can synchronously drive the cleaning blade 25 and the several brush plate seats 31 to reciprocate, so that the cleaning blade 25 cleans the scraping end of the scraper plate 21, and the several brush plate seats 31 drive the cleaning brush plate 5 to clean the conveyor belt 14.

[0031] When in use, the material is put from the loading end of the conveyor frame 1 to the conveyor belt 14, and the running conveyor belt 14 delivers the material to the unloading end, and the material is unloaded from its unloading end. During this process, some materials will adhere to the conveyor belt 14. As the conveyor belt 14 continues to run, the conveyor belt 14 will first pass through the scraper assembly 2. During this process, the conveyor belt 14 moves toward the scraper plate 21 with the materials attached thereto. The scraper plate 21 scrapes off most of the attached materials through its scraper end that contacts the conveyor belt 14, and loosens a small part of the remaining materials. At the same time, the driving assembly 6 drives the cleaning scraper 25 to move back and forth on the scraper plate 21 to scrape off the materials adhered to the scraper plate 21 to prevent the materials from accumulating thereon. 14 will continue to move to the cleaning brush mechanism 3, and the driving component 6 will synchronously drive all the brush plate seats 31 to drive the cleaning brush plates 5 to brush back and forth on the conveyor belt 14, wherein the staggered brush plate seats 31 will move toward each other, so that the cleaning brush plates 5 can comprehensively clean the conveyor belt 14, and the cleaning brush plates 5 will drive the bristles 51 thereon to swing on the conveyor belt 14 when moving back and forth, thereby increasing the brushing force to remove the residual materials on the conveyor belt 14, and after the conveyor belt 14 passes through the cleaning brush mechanism 3, all cleaning is completed, so that the surface of the conveyor belt 14 is kept clean, and when maintaining the device, the cleaning brush plate 5 with damaged bristles 51 can be quickly removed from the brush plate seat 31 through the locking component 4, and a new cleaning brush plate 5 can be fixed to the brush plate seat 31 for next use.

[0032] The difference from the above embodiment lies in that a mounting plate 211 is provided under the scraper plate 21, and limiting grooves 2112 are provided at both ends of the upper side of the mounting plate 211, and limiting slide bars 212 are welded at both ends of the lower side of the scraper plate 21, and the limiting slide bars 212 are slidably installed in the limiting grooves 2112, and a plurality of evenly arranged spring mounting grooves 2111 are also provided on the upper side of the mounting plate 211, and the plurality of spring mounting grooves 2111 are located between the limiting grooves 2112 at both ends, and a supporting spring 22 is provided in each spring mounting groove 2111, and the two ends of the supporting spring 22 are respectively fixedly connected to the bottom of the spring mounting groove 2111 and the bottom of the scraper plate 21, and the supporting spring 22 pushes the scraping end of the scraper plate 21 to contact the conveyor belt 14.

[0033] Among them, when the scraper plate 21 scrapes the material adhered to the conveyor belt 14, the support spring 22 pushes the scraper plate 21 upward, so that the scraping end of the scraper plate 21 contacts the conveyor belt 14, and most of the material adhered to the conveyor belt 14 is scraped off. When the material adhered to the conveyor belt 14 is very difficult to scrape off, the part of the material protruding from the conveyor belt 14 will push the scraper plate 21 downward to separate from the conveyor belt 14, and compress the support spring 22, passing through the scraper assembly 2, preventing the scraper from scraping the material forcefully and causing damage to the conveyor belt 14. After it passes through the scraper assembly 2, the compressed support spring 22 recovers its deformation and pushes up the scraper plate 21 again, so that the scraping end of the scraper plate 21 contacts the conveyor belt 14 again, and scrapes the subsequent material.

[0034] The difference from the above embodiment lies in that a sliding groove 2113 is provided on one side of the mounting plate 211, a screw rod 23 is rotatably installed in the sliding groove 2113, one end of the screw rod 23 extends out from the sliding groove 2113, a cleaning gear 231 is coaxially fixedly connected to the extended end of the screw rod 23, both sides of the cleaning scraper 25 are shovel-shaped and tightly attached to the scraping end of the scraper plate 21, a lever 24 is fixedly connected to the lower end of the cleaning scraper 25, the lever 24 is fixedly connected to the sliding block 241, the sliding block 241 is slidably installed in the sliding groove 2113, and the sliding block 241 is assembled on the screw rod 23 by threads.

[0035] When the driving component 6 drives the scraper gear 231 to rotate forward, the scraper gear 231 drives the screw rod 23 to rotate in the same direction, driving the lever 24 to move toward the opposite side in the sliding groove 2113. When the driving component 6 drives the scraper gear 231 to rotate reversely, the scraper gear 231 drives the screw rod 23 to rotate in the same direction, driving the lever 24 to move back to its original position from the opposite side of the sliding groove 2113. The lever 24 thereby scrapes off the material gathered on the scraping end of the scraper plate 21 through the scraper blade 25.

[0036] The difference from the above-mentioned embodiment lies in that, slots 311 are provided on both sides of the upper side of the brush plate seat 31, and a number of evenly arranged limiting slots 312 are provided between the slots 311 on both sides, and the top block 32 is slidably installed in the limiting slots 312. The two sides of the upper end of the top block 32 are inclined, and a buffer spring 33 is fixedly connected between the bottom of the top block 32 and the bottom of the limiting slot 312. The buffer spring 33 pushes the top block 32 out of the limiting slot 312, and a locking slot 313 is provided at one end of the brush plate seat 31. The locking slot 313 is provided between the slots 311 on both sides and is located on one side of the limiting slot 312, and a spring seat 3131 is fixedly connected in the locking slot 313.

[0037] The difference from the above-mentioned embodiment is that a plurality of reverse threaded rods 34 and a plurality of forward threaded rods 35 are rotatably connected to the conveyor frame 1, and the forward threaded rods 35 are alternately arranged with the reverse threaded rods 34. A guide rod 36 is provided on one side of each reverse threaded rod 34 or the forward threaded rod 35, and the guide rod 36 is fixedly connected to the conveyor frame 1. The brush plate seats 31 close to the driving assembly 6 are all threadedly assembled on the reverse threaded rod 34 and slidingly cooperate with the guide rod 36. The brush plate seats 31 away from the driving assembly 6 are all threadedly assembled on the forward threaded rod 35 and slidingly cooperate with the guide rod 36. One end of the reverse threaded rod 34 and the forward threaded rod 35 are coaxially fixedly connected with a brush cleaning gear 37.

[0038] Among them, the thread directions of the reverse threaded rod 34 and the forward threaded rod 35 are opposite. When the driving component 6 drives the brush cleaning gear 37 to rotate forward, the reverse threaded rod 34 rotates in the same direction, and the brush plate seat 31 thereon moves toward the opposite side under the drive of the reverse threaded rod 34. The forward threaded rod 35 rotates in the same direction, and the brush plate seat 31 thereon moves toward the opposite side under the drive of the forward threaded rod 35. The brush plate seat 31 on the reverse threaded rod 34 and the brush plate seat 31 on the forward threaded rod 35 move toward each other synchronously. When the driving component 6 drives the brush cleaning gear 37 to rotate reversely, the reverse threaded rod 34 and the forward threaded rod 35 rotate in the same direction, driving the brush plate seats 31 on both of them to return to their original positions from the opposite side.

[0039] The difference from the above embodiment is that the locking assembly 4 includes a locking plate 41 and a push plate 43, the locking plate 41 is slidably installed in the locking groove 313, the two sides of the bottom of the locking plate 41 are inclined, and a locking spring 42 is fixedly connected between the lower side of the locking plate 41 and the bottom of the locking groove 313, the locking spring 42 pushes the locking plate 41 to extend out of the locking groove 313, the push plate 43 is arranged on one side of the brush plate seat 31, and a push rod 44 is welded on both sides of the side surface, the push rod 44 is slidably connected in the locking groove 313, the lower side of the push rod 44 is wedge-shaped and corresponds to the inclined surfaces on both sides of the locking plate 41, and a pressure spring 45 is arranged on the push plate 43, the pressure spring 45 is located between the two push rods 44, and the pressure spring 45 is fixedly connected between the push plate 43 and the spring seat 3131.

[0040] When the cleaning brush plate 5 is replaced, the push plate 43 is first pushed into the locking groove 313 and the pressure spring 45 is compressed. The push plate 43 drives the push rod 44 to move deeper into the locking groove 313. The push rod 44 contacts the inclined surface of the bottom of the locking plate 41 through its lower side, presses the bottom of the locking plate 41 to the bottom of the locking groove 313, and retracts the locking plate 41 into the locking groove 313. , and compress the locking spring 42, the locking plate 41 stops blocking the baffle 54, and the old cleaning brush plate 5 is removed, and then the new cleaning brush plate 5 is pushed into the slot 311. When one end of the cleaning brush plate 5 hits the side wall of the slot 311, the push plate 43 is released, and the compressed pressing spring 45 recovers its deformation, pushing the push plate 43 out of the locking slot 313. The push plate 43 pulls the push rod 44 away from the bottom of the locking plate 41, ending the pressure on the bottom of the locking plate 41. The compressed locking spring 42 recovers its deformation, pushing the locking plate 41 out of the locking slot 313, and the locking plate 41 blocks the baffle 54, fixing the cleaning brush plate 5 on the brush plate seat 31.

[0041] The difference from the above embodiment is that connecting plates 52 are welded on both sides of the bottom of the cleaning brush plate 5, and the connecting plates 52 are slidably installed in the card slot 311. The bottom of the cleaning brush plate 5 is also fixedly connected to a plurality of wedge blocks 53, and the wedge blocks 53 are located between the connecting plates 52 on both sides and correspond to the top block 32, and the two sides of the wedge blocks 53 are inclined. A baffle plate 54 is fixedly connected to the bottom of one end of the cleaning brush plate 5, and the baffle plate 54 corresponds to the locking plate 41.

[0042] Among them, the inclined two sides of the cleaning brush plate 5 cover the brush plate seat 31 to prevent the brushed materials from falling onto the brush plate seat 31 and affecting the operation of the brush plate seat 31. When the cleaning brush plate 5 is fixed to the brush plate seat 31, the buffer spring 33 pushes the top block 32 upward, so that the top block 32 contacts the wedge block 53, thereby lifting the cleaning brush plate 5 so that the bristles 51 of the cleaning brush plate 5 are in full contact with the conveyor belt 14. When a new cleaning brush plate 5 is installed on the brush plate seat 31, the connecting plate 52 of the cleaning brush plate 5 is aligned with the card slot 311, and the cleaning brush plate 5 is pushed into the card slot 311. The wedge block 53 on the cleaning brush plate 5 presses the passing top block 32 back into the limiting groove 312, and the buffer spring 33 is compressed. After the wedge block 53 passes, the compressed buffer spring 33 recovers its deformation and lifts the top block 32.

[0043] The difference from the above embodiment is that a driving groove 11 and a slideway 12 are sequentially opened on one side of the conveyor frame 1 , and a conveying motor 13 is fixedly installed on one side of the feeding end of the conveyor frame 1 , and the conveying motor 13 cooperates with a conveyor belt 14 .

[0044] When the device is started, the conveying motor 13 drives the conveying belt 14 to operate and start conveying materials.

[0045] The difference from the above embodiment is that the driving assembly 6 includes a driving motor 61, a driving connecting rod 63 and a sliding plate 64. The driving motor 61 is fixedly installed on the outer side of the driving groove 11. The output shaft of the driving motor 61 passes through the driving groove 11, and is fixedly connected to an eccentric wheel 62. An eccentric shaft 621 is eccentrically provided on one side of the eccentric wheel 62. The eccentric shaft 621 is rotatably connected to one end of the driving connecting rod 63. The other end of the driving connecting rod 63 is rotatably connected to one end of the sliding plate 64. The sliding plate 64 is slidably connected in the slideway 12. A driving rack 641 is provided at the bottom of the inner side of the sliding plate 64. The driving rack 641 is meshed with the brush cleaning gear 37 and the scraper cleaning gear 231.

[0046] Among them, when the conveying motor 13 is started, the driving motor 61 is also started synchronously. The driving motor 61 drives the eccentric wheel 62 to rotate, so that the eccentric wheel 62 drives the sliding plate 64 to move back and forth in the slide 12 through the driving connecting rod 63. When the driving connecting rod 63 pushes the sliding plate 64 to move in the slide 12, the sliding plate 64 moves toward the unloading end, and the sliding plate 64 thereby drives the scraping gear 231 and the brushing gear 37 to rotate forward. When the driving connecting rod 63 pulls the sliding plate 64 to move in the slide 12, the sliding plate 64 moves away from the unloading end, and the sliding plate 64 thereby drives the scraping gear 231 and the brushing gear 37 to rotate in the opposite direction through the driving rack 641.

[0047] Embodiment 2; the difference from the above embodiment is that the receiving frame 7 is movably mounted at the discharge end of the conveyor frame 1, located below the scraper assembly 2 and the brushing mechanism 3.

[0048] When the conveyor belt 14 is working, the materials cleaned by the scraper assembly 2 and the brushing mechanism 3 will fall into the material receiving frame 7, and these materials will be processed centrally.

[0049] Working principle: When in use, the material is put from the loading end of the conveyor frame 1 to the conveyor belt 14, and the running conveyor belt 14 delivers the material to the unloading end, and the material is unloaded from its unloading end. In this process, some materials will adhere to the conveyor belt 14. As the conveyor belt 14 continues to run, the conveyor belt 14 will first pass through the scraper assembly 2, wherein the conveyor belt 14 moves toward the scraper plate 21 with the materials attached thereto, and the scraper plate 21 scrapes off most of the attached materials through its scraper end that contacts the conveyor belt 14, and loosens a small part of the remaining materials, and at the same time, the driving motor 61 drives the eccentric wheel 62 to rotate, so that the eccentric wheel 62 drives the sliding plate 64 to reciprocate in the slideway 12 through the driving connecting rod 63, thereby driving the scraper gear 231 and the brush gear 37 to rotate back and forth, wherein the scraper gear 231 that rotates back and forth drives the scraper blade 25 on the scraper plate The scraper end 21 moves back and forth on the scraper plate 21 to scrape off the material adhered to the scraper plate 21 to prevent the material from accumulating thereon. When the scraper plate 21 scrapes off the material adhered to the conveyor belt 14, the support spring 22 pushes the scraper plate 21 upward so that the scraping end of the scraper plate 21 contacts the conveyor belt 14 to scrape off most of the material adhered to the conveyor belt 14. When the material adhered to the conveyor belt 14 is very difficult to scrape off, the part of the material protruding from the conveyor belt 14 will push the scraper plate 21 downward to separate from the conveyor belt 14 and compress the support spring 22 to pass through the scraper assembly 2, preventing the scraper from scraping off the material forcefully and causing damage to the conveyor belt 14. After it passes through the scraper assembly 2, the compressed support spring 22 recovers its deformation and pushes up the scraper plate 21 again, so that the scraping end of the scraper plate 21 contacts the conveyor belt 14 again to scrape off the subsequent material.

[0050] The conveyor belt 14 passing through the scraper assembly 2 will continue to move to the cleaning brush mechanism 3, and the back-and-forth rotating cleaning brush gear 37 drives the staggered brush plate seat 31 to drive the cleaning brush plate 5 to move back and forth, and the conveyor belt 14 is fully cleaned. When the cleaning brush plate 5 moves back and forth, it will drive the bristles 51 thereon to swing on the conveyor belt 14, increasing the brushing force to remove the residual materials on the conveyor belt 14. After the conveyor belt 14 passes through the cleaning brush mechanism 3, all cleaning is completed, so that the surface of the conveyor belt 14 is kept clean, and the scraper assembly 2 and The materials cleaned by the cleaning brush mechanism 3 will fall into the material receiving frame 7, and these materials will be processed centrally. When maintaining the device, the cleaning brush plate 5 with damaged bristles 51 can be quickly removed from the brush plate seat 31 through the locking component 4. When the locking component 4 fixes the cleaning brush plate 5 on the brush plate seat 31, the pressing spring 45 pushes the push plate 43 outward, and the push rod 44 on the push plate 43 does not press the bottom of the locking plate 41. The locking spring 42 pushes the locking plate 41 to rise to the top of the locking groove 313. When replacing the cleaning brush plate 5, first push the push plate 43 into the locking groove 313 and compress the pressing spring 45. The push plate 43 drives the push rod 44 to move deeper into the locking groove 313. The push rod 44 contacts the inclined surface at the bottom of the locking plate 41 through its lower side inclined surface, presses the bottom of the locking plate 41 to the bottom of the locking groove 313, retracts the locking plate 41 into the locking groove 313, and compresses the locking spring 42. The locking plate 41 stops blocking the baffle 54. After the old cleaning brush plate 5 is removed, the new cleaning brush plate 5 is pushed in. When one end of the cleaning brush plate 5 hits the side wall of the slot 311 in the slot, the push plate 43 is released, and the compressed pressing spring 45 recovers its deformation and pushes the push plate 43 out of the locking slot 313. The push plate 43 pulls the push rod 44 away from the bottom of the locking plate 41, ending the pressure on the bottom of the locking plate 41. The compressed locking spring 42 recovers its deformation and pushes the locking plate 41 out of the locking slot 313. The locking plate 41 blocks the baffle 54, fixing the cleaning brush plate 5 on the brush plate seat 31 for next use.
