Description

Technical Field

[0001] The invention relates to the technical field of conveyors, and in particular to an automatic cleaning robot for rollers of belt conveyors. Background Art

[0002] Belt conveyor is a kind of conveying equipment widely used in the industrial field. It uses a closed loop belt to move between two or more rollers to convey various materials. The working principle of the belt conveyor is to use the friction between the driving roller and the belt to drive the belt, and the belt then drives the material to move together. The material is placed on the upper branch of the belt. As the belt moves, the material is transported to the designated location. The design and selection of the belt conveyor need to be comprehensively considered according to the characteristics of the material, the conveying volume, the conveying distance, the working environment and other factors. With the development of technology, modern belt conveyors are becoming more and more automated and intelligent to improve the efficiency and safety of transportation.

[0003] Most of the rollers on existing belt conveyors are not equipped with cleaning devices. After long-term use, powdery substances and other debris will adhere to the surface of the roller, making the surface of the roller no longer smooth.

[0015] In summary, due to the adoption of the above-mentioned technology of an automatic cleaning robot for the rollers of a belt conveyor, the beneficial effects of the present invention are: 1.

At this time, the scraper is located at the bottom of the roller. While rising, water can be pumped out of the water tank by the water pump and conveyed into the water delivery pipe, and the water is atomized and sprayed onto one of the sponge sleeves through the atomizing nozzles on its surface to wet its surface. At this time, the roller is in a low-speed rotation state. Due to the frictional force generated by contacting the two sponge sleeves, the two sponge sleeves follow the rotation. The wet sponge sleeve wipes and cleans the surface of the roller, and the other dry sponge sleeve dries the wet part of the roller surface. If there are large-particle impurities on the surface of the roller, at this time, the scraper scrapes off the large-particle impurities on its surface, thus realizing the cleaning of the roller. At the same time, the fixing of the sponge sleeve can be released through the fixing component, which is convenient for replacement.

[0016] 2. By setting up a feeding component, after the fixing of the sponge sleeve is released, the rectangular plate is driven to rise by the second electric telescopic rod, and the rectangular plate will drive the rack and the L-shaped rod to rise. The rack makes the ratchet wheel and the circular plate rotate through meshing. The abutting block rises through the eccentrically arranged traction plate to contact and squeeze the bottom of the sponge sleeve, so that the sponge sleeve slides off the top of the vertical plate, thus realizing automatic discharging. At the same time, the L-shaped rod enters the installation box through the through groove, and the L-shaped rod also drives the moving plate at the same time. The abutting plate is driven by the third rope, so that the sponge sleeve stored in the installation box can slide to the top of the vertical plate, thus realizing automatic feeding.

Detailed implementation manners

[0023] Next, the technical solution of an automatic cleaning robot for the roller of a belt conveyor will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] As Figure 1 - Figure 5As shown in the figure, the present invention provides an automatic cleaning robot for the rollers of a belt conveyor, which includes a conveying frame 10. A plurality of rollers 11 are rotatably connected to the top of the conveying frame 10. A belt 12 is used to drive and connect between the plurality of rollers 11. The conveying frame 10, the rollers 11 and the belt 12 are all components on a belt conveyor in the prior art. A cleaning component 20 is arranged on the conveying frame 10. The cleaning component 20 includes a mounting plate 21 and a cross plate 22 fixedly installed on the conveying frame 10. A first electric telescopic rod 23 is fixedly installed on the top of the cross plate 22. The output end of the first electric telescopic rod 23 is fixedly connected to a support plate 24. The support plate 24 is driven to lift by the first electric telescopic rod 23. Vertical plates 25 are symmetrically installed at the top of the support plate 24. When the support plate 24 lifts, the vertical plates 25 are driven to lift at the same time. A wiping component 26 and a fixing component 27 are arranged at the top of the vertical plates 25. The roller 11 can be cleaned by the wiping component 26, and at the same time, the wiping component 26 after cleaning can be replaced in cooperation with the fixing component 27; It further includes a feeding component 30 arranged on the mounting plate 21. The feeding component 30 includes a second electric telescopic rod and a water tank fixedly installed on the top of the cross plate 22. The output end of the second electric telescopic rod is fixedly connected to a rectangular plate 31. Long blocks 32 are symmetrically installed at the top of the rectangular plate 31. An inclined plate 33 is fixedly connected between the tops of the two long blocks 32. The rectangular plate 31 is driven to lift by the second electric telescopic rod. When the rectangular plate 31 lifts, the long blocks 32 and the inclined plate 33 are driven to rise at the same time. A storage box 34 is placed on the top of the mounting plate 21. The replaced sponge sleeve 26a is stored by the storage box 34. A blanking component 35 and a replenishing component 36 are arranged on the rectangular plate 31. The cleaned sponge sleeve 26a can be automatically blanked through the blanking component 35, and at the same time, the sponge sleeve 26a can be automatically fed in cooperation with the replenishing component 36.

[0025] More specifically, the wiping component 26 includes a sponge sleeve 26a and a concave frame 26b arranged between the two vertical plates 25. Two sponge sleeves 26a are in a group. A water spray pipe 26c is fixedly connected to the top of the concave frame 26b. A water delivery pipe 26d is fixedly communicated with one side of the water spray pipe 26c. An electromagnetic valve (not marked in the figure) is arranged on the water delivery pipe 26d. The other end of the water delivery pipe 26d is communicated with the water tank. A water pump is also arranged on the water tank. The output end of the water pump is communicated with the water delivery pipe 26d. Water can be pumped out of the water tank by the water pump and conveyed into the water delivery pipe 26d. The water flow entering is controlled by the electromagnetic valve on the surface of the water delivery pipe 26d. Then the water is atomized and sprayed onto one of the sponge sleeves 26a through the atomizing nozzle, and its surface is wetted. The surface of the roller 11 is wiped and cleaned by the wet sponge sleeve 26a, and the other dry sponge sleeve 26a dries the wet part on the surface of the roller 11.

[0026] More specifically, an atomizing nozzle is provided on one side of the water spray pipe 26c close to the sponge sleeve 26a. The atomizing nozzle is a prior art. Through the small apertures on the atomizing nozzle, due to the pressure difference, the water flow is torn into small water droplets and ejected. There is a gap between the concave surface of the concave-shaped frame 26b and the vertical plate 25. Through the gap, the wet sponge sleeve 26a can fall into the storage box 34 at the bottom for collection. One side of the scraping plate 26e close to the sponge sleeve 26a is set as an inclined surface. The scraping plate 26e is located between the two sponge sleeves 26a. The large-particle impurities on the surface of the roller 11 are cleaned by the scraping plate 26e. The collection box 26f is located below the scraping plate 26e, and the large-particle impurities after cleaning will fall into the collection box 26f through the inclined surface at the top of the scraping plate 26e for storage. The collection box 26f can be disassembled and cleaned.

[0027] Operation process: When cleaning the roller 11, first start a number of first electric telescopic rods 23 to synchronously drive the support plate 24 to rise. While the support plate 24 rises, it drives the vertical plate 25 to rise. While the vertical plate 25 rises, it drives the two sponge sleeves 26a to rise, so that the two sponge sleeves 26a are respectively located on both sides of the roller 11. At this time, the scraping plate 26e is located at the bottom of the roller 11. While rising, water can be pumped out of the water tank by a water pump and conveyed into the water delivery pipe 26d. The water flow entering is controlled by the solenoid valve on the surface of the water delivery pipe 26d. Then, the water is atomized and sprayed onto one of the sponge sleeves 26a through the atomizing nozzle to wet its surface and make contact with the surface of the roller 11. At this time, the roller 11 is in a low-speed rotation state. Due to the frictional force generated by contact with the two sponge sleeves 26a, the two sponge sleeves 26a will follow the rotation. The wet sponge sleeve 26a wipes and cleans the surface of the roller 11, and the other dry sponge sleeve 26a dries the wet part of the surface of the roller 11. If there are large-particle impurities on the surface of the roller 11, at this time, the scraping plate 26e scrapes off the large-particle impurities on its surface, and the large-particle impurities after cleaning will fall into the collection box 26f through the inclined surface at the top of the scraping plate 26e for temporary storage. After the cleaning is completed, at this time, start a number of first electric telescopic rods 23 again to synchronously drive the support plate 24 to descend, thereby driving the sponge sleeve 26a and the scraping plate 26e to descend.

[0028] Such as Figure 6 - Figure 7As shown in the figure, the fixing component 27 includes a fixing block 27a arranged at the top of the vertical plate 25. The bottom end of the fixing block 27a is in contact with the top of the vertical plate 25. Connecting plates 27b fixedly installed on both sides of the fixing block 27a. There are two groups of connecting plates 27b. A clamping block 27c is slidably connected to one side of the vertical plate 25. One side of the clamping block 27c is fixedly connected to a first rope 27d. A cavity is formed in the middle of the vertical plate 25. A sliding plate 27e and a square plate 27f are slidably connected inside the cavity. The sliding plate 27e and the square plate 27f are connected by a second rope 27g. A lifting plate 27h is slidably connected to the side of the vertical plate 25 away from the first rope 27d. An arc-shaped frame 27i and a magnet 27j are fixedly connected to the lifting plate 27h. Baffles 27k and limit blocks 27l are symmetrically arranged on both sides of the cavity.

[0029] More specifically, the lengths of the two groups of connecting plates 27b are different. The clamping block 27c is engaged with one of the connecting plates 27b. The other end of the first rope 27d is fixedly installed on the sliding plate 27e. Return springs are arranged on both the sliding plate 27e and the clamping block 27c. The sponge sleeve 26a is located between the vertical plate 25 and the fixing block 27a. The second rope 27g is pulled by the lifting of the square plate 27f, so that the sliding plate 27e moves accordingly, thereby pulling the first rope 27d and driving the clamping block 27c to move, so as to disengage from the matching connecting plate 27b, thus releasing the limit on the fixing block 27a. At the same time, the sliding plate 27e and the clamping block 27c can be reset by the reaction force of the return spring.

[0030] More specifically, a metal sheet is arranged on the top of the square plate 27f. The magnet 27j is adsorbed to the metal sheet. The baffles 27k and the limit blocks 27l are located above the square plate 27f. A spring is arranged between the limit block 27l and the cavity. The arc-shaped frame 27i is located directly below the other group of connecting plates 27b. When the vertical plate 25 descends, the lifting plate 27h on one side of it will contact the top end of the mounting plate 21. As the vertical plate 25 descends, at this time the arc-shaped frame 27i will gradually contact the corresponding connecting plate 27b and push it upward, driving the fixing block 27a to separate from the vertical plate 25. At the same time, the square plate 27f will also be driven to rise by the adsorption force of the magnet 27j.

[0031] Operation process: When the vertical plate 25 descends, the lifting plate 27h on one side of it will contact the top of the mounting plate 21 and block it, preventing it from descending. As the vertical plate 25 descends, the arc-shaped frame 27i at the top of the lifting plate 27h will gradually contact the corresponding connecting plate 27b and push it upward. At the same time, the square plate 27f will be driven to rise by the adsorption force of the magnet 27j. When the square plate 27f rises, the second rope 27g will be pulled, causing the sliding plate 27e to move accordingly, thereby pulling the first rope 27d and driving the clamping block 27c to move, so as to disengage from the matching connecting plate 27b and release the limit on the fixed block 27a; When the square plate 27f rises, it will first contact the limiting block 27l and squeeze it through its arc surface. After the square plate 27f rises to the apex, at this time, the square plate 27f will be located between the limiting block 27l and the baffle 27k. At the same time, the baffle 27k will block the square plate 27f, preventing it from moving with the lifting plate 27h any more, and disengaging from the adsorption of the magnet 27j and being supported by the limiting block 27l. At this time, the arc-shaped frame 27i gradually pushes the corresponding connecting plate 27b, causing it to drive the fixed block 27a to separate from the vertical plate 25, thereby releasing the fixation of the sponge sleeve 26a.

[0032] As Figure 8 - Figure 12 As shown in the figure, the blanking assembly 35 includes racks 35a symmetrically installed on the rectangular plate 31. The bottom end of the mounting plate 21 is symmetrically installed with T-shaped frames 35b. One side of the T-shaped frame 35b is rotatably installed with a rotating shaft 35c. A ratchet wheel 35d and a circular plate 35e are fixedly connected to the rotating shaft 35c. The ratchet wheel 35d and the circular plate 35e can rotate through the rotating shaft 35c. The ratchet wheel 35d is a prior art. When the ratchet wheel 35d rotates clockwise, it will drive the entire rotating shaft 35c to rotate. When the ratchet wheel 35d rotates counterclockwise, it will only idle on the surface of the rotating shaft 35c and will not drive it to rotate. A contact block 35f is rotatably connected to the side of the circular plate 35e away from the ratchet wheel 35d. The circular plate 35e and the contact block 35f are connected by a traction plate. The traction plate is rotatably connected to the circular plate 35e and the contact block 35f.

[0033] More specifically, the rack 35a meshes with the ratchet wheel 35d. The traction plate is eccentrically arranged on the circular plate 35e. The top end of the abutting block 35f penetrates and extends above the mounting plate 21. The top end of the side of the abutting block 35f close to the storage box 34 is arranged as an arc surface. Guide plates are installed on both sides of the storage box 34. After the limit on the sponge sleeve 26a is released, the second electric telescopic rod is started at this time to drive the rectangular plate 31 to rise. While the rectangular plate 31 rises, it drives the rack 35a to rise. Through meshing, the ratchet wheel 35d rotates clockwise, and then the rotating shaft 35c and the circular plate 35e rotate. While the circular plate 35e rotates, it drives the traction plate and pulls the abutting block 35f to rise. After the traction plate rotates to the vertex of the circular plate 35e, at this time, the abutting block 35f also contacts the bottom end of the sponge sleeve 26a and pushes it upward, so that the sponge sleeve 26a moves out from the top of the vertical plate 25, and then slides downward through the inclined surface at the top of the abutting block 35f. The dry sponge sleeve 26a falls into the storage box 34 on the other side through the guide plate, and the gravity of the wet sponge sleeve 26a increases, and it will fall into the storage box 34 on the other side for storage from the gap between the concave surface of the concave frame 26b and the vertical plate 25. At this time, as the rectangular plate 31 continues to rise, the ratchet wheel 35d and the rack 35a will disengage from meshing. At this time, the abutting block 35f drops due to gravity and drives the traction plate to rotate the circular plate 35e and the ratchet wheel 35d. At this time, the traction plate returns to the lowest point of the circular plate 35e.

[0034] More specifically, the feeding assembly 36 includes L-shaped rods 36a symmetrically installed on the rectangular plate 31. An installation box 36b is arranged between the opposite surfaces of the conveying frame 10. Unused sponge sleeves 26a are stored inside the installation box 36b. The two sides of the installation box 36b are both slidably connected with abutting plates 36c. The sponge sleeves 26a inside the installation box 36b are blocked by the abutting plates 36c to prevent the sponge sleeves 26a from slipping out of the installation box 36b. The two sides of the bottom end of the installation box 36b are both slidably connected with moving plates 36d. A third rope 36e is arranged between the moving plate 36d and the abutting plate 36c. Only when the moving plate 36d is pushed upward and the third rope 36e is stretched to make the abutting plate 36c drop, can the sponge sleeves 26a inside the installation box 36b slide down.

[0035] More specifically, through slots are symmetrically formed at the bottom end of the installation box 36b. The size of the through slots is the same as that of the L-shaped rod 36a. Installation holes (not marked in the figure) are formed on both sides of the installation box 36b and at both ends of the conveying frame. Through the installation holes, sponge sleeves 26a can be placed inside the installation box 36b. A connecting spring is arranged between the pressing plate 36c and the installation box 36b. Arc-shaped blocks are symmetrically arranged on one side of the installation box 36b close to the scraping plate 26e. While the rectangular plate 31 rises, the L-shaped rod 36a will also be driven to rise. As the rectangular plate 31 gradually rises, the top end of the L-shaped rod 36a will enter the interior of the installation box 36b through the through slots. At this time, the top end of the L-shaped rod 36a will contact one side of the sponge sleeve 26a, thereby pushing the sponge sleeve 26a out of the installation box 36b and making it slide onto the top end of the vertical plate 25, thus realizing automatic feeding.

[0036] Operation process: After releasing the fixation of the sponge sleeve 26a, the second electric telescopic rod is started at this time to drive the rectangular plate 31 to rise. While the rectangular plate 31 rises, the rack 35a is driven to rise. Through meshing, the ratchet wheel 35d rotates clockwise, and then the rotating shaft 35c and the circular plate 35e rotate. While the circular plate 35e rotates, the traction plate is driven, and the abutting block 35f is pulled to rise. After the traction plate rotates to the vertex of the circular plate 35e, at this time, the abutting block 35f will also contact the bottom end of the sponge sleeve 26a and push it upward, so that the sponge sleeve 26a is moved out from the top of the vertical plate 25, and then slides downward through the inclined surface at the top of the abutting block 35f. The dry sponge sleeve 26a falls into the storage box 34 on the other side through the guiding plate, while the gravity of the wet sponge sleeve 26a increases, and it will fall into the storage box 34 on the other side through the gap between the concave surface of the concave-shaped frame 26b and the vertical plate 25 for storage; At this time, as the rectangular plate 31 continues to rise, the ratchet wheel 35d and the rack 35a will disengage from meshing. At this time, the abutting block 35f drops due to gravity, and drives the traction plate to rotate the circular plate 35e and the ratchet wheel 35d. At this time, the traction plate returns to the lowest point of the circular plate 35e, and the rectangular plate 31 continues to rise. At the same time, the L-shaped rod 36a is also driven to rise. As the rectangular plate 31 gradually rises, the top end of the L-shaped rod 36a will enter the interior of the installation box 36b through the through slots. While one side of the L-shaped rod 36a rises, it will also contact one side of the moving plate 36d and push it to rise. By stretching the third rope 36e, the pressing plate 36c is lowered. At this time, the top end of the L-shaped rod 36a will contact one side of the sponge sleeve 26a, thereby pushing the sponge sleeve 26a out of the installation box 36b, and making it slide onto the top ends of the vertical plates 25 on both sides through the inclined plate 33 and the arc-shaped blocks respectively, thus realizing automatic feeding; Next, the second electric telescopic rod is driven to lower the rectangular plate 31 to reset it. After the L-shaped rod 36a descends, it will disengage from the side of the moving plate 36d. At this time, the connecting spring causes the abutting plate 36c to reset, and once again blocks the sponge sleeve 26a inside the storage box 34. At this time, the rack 35a will mesh with the ratchet 35d again. Since the rack 35a will cause the ratchet 35d to rotate counterclockwise when descending, the ratchet 35d will only rotate idly. After the rectangular plate 31 is reset, the first electric telescopic rod 23 is started to drive the support plate 24 to rise. Due to gravity, the fixed block 27a and the lifting plate 27h descend. At this time, the magnet 27j will adsorb to the square plate 27f again, and at the same time, the weight of the square plate 27f itself will also increase, and then it descends. The reset spring causes the sliding plate 27e and the clamping block 27c to reset, and the fixed block 27a is limited again through clamping, so as to fix the replaced sponge sleeve 26a.
