Description

Technical Field

[0001] The present invention relates to the technical field of belt conveyors, and particularly relates to a belt conveyor with an automatic cleaning function. Background Art

[0002] A belt conveyor is a conveying device that drives a conveyor belt to rotate to drive materials to move. Its main components include a motor, a conveyor belt, and a driving roller. It is extremely common in industrial production. After long-term use of traditional belt conveyors, due to the accumulation of material residues, dust, or powder, it may lead to an increase in adhesion on the belt surface, an increase in friction, and even problems such as a decrease in transportation efficiency, an increase in energy consumption, and potential safety hazards. Therefore, a certain cleaning structure needs to be set up to deal with it to extend the service life of the device;

[0003] The utility model with the publication number CN215709620U discloses a full-automatic cleaner for a belt conveyor. By installing a limit guide rail, the moving bracket can be limited to prevent the moving bracket from shaking during movement, increasing the stability of the device. Installing a cleaning brush wheel can quickly clean up debris, prevent the debris from corroding the conveyor belt and affecting its service life, and increase the practicality of the device. Installing support legs can increase the stability of the device and prevent the device from tilting. By installing a limit bracket, it can support the moving bracket, prevent it from tilting, and at the same time reduce the pressure on the limit guide rail and increase its service life. Installing a cleaning motor can drive the cleaning brush wheel to rotate to ensure the integrity of the device's functionality. Installing a waste suction fan can prevent debris from splashing out of the device and prevent environmental pollution;

[0004] The above-mentioned existing technical components have certain deficiencies in actual use. When using structures such as cleaning brush wheels to clean the equipment, an additional cleaning motor needs to be set up for driving, so additional energy consumption is required on the basis of the original energy consumption.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention 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 creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-8 As shown, the present invention is a belt conveyor with an automatic cleaning function, including a bracket 1. A first toothed disc 9 is arranged on the surface of the bracket 1 near one end edge. A docking wheel 17 is arranged on the surface of the bracket 1 on one side of the first toothed disc 9. A connecting frame 30 is arranged on the surface of the docking wheel 17. A positioning seat 34 is fixedly installed on one end surface of the bracket 1;

[0030] One end surface of the first toothed disc 9 is meshed and connected with a chain 11. The inner side of the chain 11 is meshed and connected with a second toothed disc 12. One end surface of the second toothed disc 12 is concentrically connected with a second toothed disc 12. The surface of the second toothed disc 12 is meshed and connected with a third toothed disc 13. A fourth toothed disc 14 is rotatably connected on the surface of the bracket 1 on one side of the third toothed disc 13. The third toothed disc 13 and the fourth toothed disc 14 are meshed and connected. The other end surface of the first toothed disc 9 is fixedly connected with a sleeve disc. A belt 16 is sleeved on the surface of the sleeve disc. The belt 16 is sleeved and connected with the docking wheel 17;

[0031] A motor 2 is fixedly installed on the bottom surface of the support 1. The output end of the motor 2 is fixedly installed with a driving wheel 3. The surface of the support 1 is symmetrically rotatably connected with conveyor rollers 4. One end of one of the conveyor rollers 4 is fixedly installed with a driven wheel 5. A conveyor belt 6 is sleeved and connected on the surface of the conveyor roller 4. The driving wheel 3 and the driven wheel 5 are connected by a transmission belt. Guide frames 7 are symmetrically and fixedly installed on the top surface of the support 1 near one end edge. A protective shell 8 is fixedly installed on one end surface of the support 1 below the guide frame 7. After placing this belt conveyor at the working location and starting the motor 2, the driving wheel 3 on its output end will drive the driven wheel 5 to rotate, thereby controlling the rotation of the conveyor roller 4 connected to the driven wheel 5, so that the items placed on the surface of the conveyor belt 6 will move towards the guide frame 7 and be concentrated in the middle under its influence to complete the blanking;

[0032] One end surface of the first tooth disc 9 is concentrically and fixedly connected with a connecting shaft 10. One of the conveyor rollers 4 is fixedly connected with the connecting shaft 10. A cleaning roller 15 is fixedly connected to the surface of the fourth tooth disc 14. There may be some fine impurities or dirt adhering to the surface of the conveyor belt 6 after the scraping treatment. As the conveyor belt 6 rotates, its surface with impurities and dirt will slowly approach the cleaning roller 15. Before that, as the conveyor roller 4 rotates, the first tooth disc 9 connected to it can rotate together, and through the transmission of the chain 11, the second tooth disc 12 and the third tooth disc 13, finally the fourth tooth disc 14 meshing on the surface of the third tooth disc 13 rotates, thereby driving the cleaning roller 15 to continuously brush the surface of the conveyor belt 6 to ensure that the conveyor belt 6 can be cleaned as much as possible and reduce the subsequent manual maintenance and cleaning workload;

[0033] One end surface of the docking wheel 17 is fixedly connected with a connecting shaft 18. One end surface of the connecting shaft 18 is fixedly connected with a disc 19. One end surface of the disc 19 is fixedly connected with a first tooth group 20. The other end surface of the disc 19 is fixedly connected with a second tooth group 21 at the staggered position of the first tooth group 20. A connecting rod 26 is fixedly connected to the surface of the support 1 at the docking wheel 17;

[0034] A positioning frame 25 is fixedly connected to the surface of the connecting rod 26. There are positioning holes on the surface of the positioning frame 25. A first gear 22 is rotatably connected to the surface of one of the positioning holes. A sleeve wheel 23 is fixedly connected to the surface of the first gear 22. A sleeve belt 24 is sleeved and connected on the surface of the sleeve wheel 23. A second gear 27 is rotatably connected to the surface of the other positioning hole. One end surface of the second gear 27 is fixedly connected with an extension rod 28. A reciprocating groove 29 is provided on the surface of the extension rod 28;

[0035] The surface of the extension rod 28 is sleeved and connected with a connecting frame 30. Slots are symmetrically arranged on the surface of the connecting frame 30 near the two ends' edges. Inside the slots, clamping blocks 31 are symmetrically and fixedly connected. The clamping blocks 31 are embedded and connected with the reciprocating slots 29. The top surface of the connecting frame 30 is fixedly connected with a long plate 32, and the top surface of the long plate 32 is fixedly connected with bristles 33;

[0036] A connecting bolt 35 is fixedly connected to the surface of the positioning seat 34. A spring 36 is sleeved and connected to the surface of the connecting bolt 35. A backing plate 37 is arranged on the surface of the connecting bolt 35 above the spring 36. Scraper blades 38 are equidistantly and rotatably connected to one long side surface of the backing plate 37;

[0037] One end surface of the scraper blade 38 is fixedly connected with a short shaft 39, one end surface of the short shaft 39 is fixedly connected with a round wheel 40, and a guiding belt 41 is sleeved and connected to the surface of the round wheel 40. During the rotation of the conveyor belt 6, there will inevitably be some impurities and dirt on its surface. In order to keep the surface of the conveyor belt 6 clean for a long time and reduce the subsequent cleaning workload of the staff, through the arranged docking wheel 17, it can rotate along with the belt 16, and at the same time, the disk 19 connected to it through the coupling shaft 18 will also rotate. During this process, once the first tooth group 20 on the surface of the disk 19 contacts the first gear 22, the sleeve wheel 23 will be driven to control the rotation of the sleeve belt 24, and one of the round wheels 40 connected to the sleeve belt 24 will rotate accordingly. Under the action of the guiding belt 41, multiple round wheels 40 will rotate simultaneously. The short shaft 39 connected to the round wheel 40 will drive the scraper blade 38 to rotate 180 degrees, that is, the scraper blade 38 is turned over, avoiding its one side facing the surface of the conveyor belt 6 for a long time, reducing the probability of impurities adhering to the surface of the scraper blade 38 and thus affecting its cleaning effect. After the scraper blade 38 is turned over, with the rotation of the disk 19, the second tooth group 21 will drive the second gear 27 to rotate. At this time, the reciprocating slot 29 on the extension rod 28 will cooperate with the clamping block 31, causing the connecting frame 30 to start reciprocating horizontally. During this process, the bristles 33 will clean the lower surface of the scraper blade 38 as they lean against it, playing a role in removing impurities and maintenance, thereby reducing the wear of the scraper blade 38.

[0038] Working principle of the present invention: After placing this belt conveyor at the working location and starting the motor 2, the driving wheel 3 on its output end will drive the driven wheel 5 to rotate, thereby controlling the rotation of the conveyor roller 4 connected to the driven wheel 5, causing the items placed on the surface of the conveyor belt 6 to move towards the guiding frame 7 and be concentrated in the middle for blanking. During the rotation of the conveyor belt 6, there will inevitably be some impurities and dirt on its surface. In order to keep the surface of the conveyor belt 6 clean for a long time and reduce the cleaning workload of subsequent workers, through the provided docking wheel 17, it can rotate along with the belt 16, and at the same time, the disc 19 connected to it through the coupling shaft 18 will also rotate. During this process, once the first tooth group 20 on the surface of the disc 19 contacts the first gear 22, the sleeve wheel 23 will be driven to control the rotation of the sleeve belt 24, and one of the round wheels 40 connected to the sleeve belt 24 will rotate accordingly. Under the action of the guiding belt 41, multiple round wheels 40 will rotate simultaneously, and the short shaft 39 connected to the round wheels 40 will drive the scraper 38 to rotate 180 degrees, that is, complete the turning of the scraper 38, avoiding one side of it from facing the surface of the conveyor belt 6 for a long time, reducing the probability of impurities adhering to the surface of the scraper 38, and thus affecting its cleaning effect. After the scraper 38 is turned over, with the rotation of the disc 19, the second tooth group 21 will drive the second gear 27 to rotate. At this time, the reciprocating groove 29 on the extension rod 28 will cooperate with the block 31, causing the connecting frame 30 to start reciprocating horizontally. During this process, the brush bristles 33 will clean the lower surface of the scraper 38 by adhering to it, playing a role in impurity removal and maintenance, thereby reducing the wear of the scraper 38. There may be some fine impurities or dirt adhering to the surface of the conveyor belt 6 after the scraping treatment. As the conveyor belt 6 rotates, its surface with adhered impurities and dirt will slowly approach the cleaning roller 15. Before that, with the rotation of the conveyor roller 4, the first tooth disc 9 connected to it will rotate accordingly, and through the transmission of the chain 11, the second tooth disc 12, and the third tooth disc 13, finally, the fourth tooth disc 14 meshed on the surface of the third tooth disc 13 will rotate, thereby driving the cleaning roller 15 to continuously brush the surface of the conveyor belt 6 to ensure that the conveyor belt 6 can be cleaned as much as possible and reduce the subsequent manual maintenance and cleaning workload.

[0039] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
