Description

Technical Field

[0001] This utility model relates to the field of cross-belt sorting machine correction technology, and in particular to a cross-belt sorting machine correction device. Background Technology

[0002] Cross-belt sorters are commonly used material handling equipment. Their working principle is that the motor drives the rotating wheel to rotate, and the rotating wheel drives the belt to move, so that the material on the belt is transported from one end to the other. During the use of cross-belt sorters, deviation often occurs.

[0003] A search revealed that patent document CN209382792U discloses a belt misalignment correction device for a conveyor belt. The device includes a conveyor belt and a correction adjustment rod with a resistance device. During the belt misalignment correction process, the correction adjustment rod applies resistance to the misaligned conveyor belt on one side through the resistance device fixed thereon to correct the misaligned conveyor belt.

[0004] In use, the above design employs a belt-correcting device consisting of a correction rod with a resistance element. During conveyor belt misalignment adjustment, the correction rod, through the resistance element fixed to it, applies resistance to the misaligned side of the conveyor belt to correct its deviation. Its working principle is based on the fact that belt misalignment is caused by different speeds on both sides of the conveyor belt due to varying frictional forces. Applying frictional resistance to the faster-moving side of the conveyor belt through the resistance element reduces its speed, ultimately achieving the correction function. However, in actual use, belt misalignment is usually caused by a skewed belt roller. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem of belt deviation caused by the skewness of the belt roller in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides a cross-belt sorting machine correction device, including a base plate, a first support frame fixedly installed on the top of the base plate, two conveyor rollers rotatably installed in the inner cavity of the first support frame, a conveyor belt is wound around the outer surface of the two conveyor rollers, a slider is rotatably connected to one end of the conveyor roller, a limit frame is fixedly installed on one side of the first support frame, the slider is slidably connected to the limit frame, and a threaded rod is rotatably connected to one side of the slider.

[0007] In one embodiment of this utility model, the inner cavity of the limiting frame is provided with a sliding groove, and the slider is slidably installed in the inner cavity of the sliding groove.

[0008] In one embodiment of the present invention, a first rotating groove is provided on one side of the slider, and two second rotating grooves are provided on the inner surface of the first rotating groove.

[0009] In one embodiment of this utility model, a rotating rod is rotatably mounted on the inner surface of the second rotating groove, and a bearing is fixedly connected to the opposite surfaces of the two rotating rods. One end of the conveying roller is slidably mounted in the inner cavity of the bearing.

[0010] In one embodiment of the present invention, a second support frame is fixedly installed on the top of the base plate, and two cleaning rollers are rotatably installed in the inner cavity of the second support frame, one of the cleaning rollers being fixedly connected to a motor at one end.

[0011] In one embodiment of this utility model, the motor is fixedly installed on one side of the second support frame, and a gear is fixedly connected to one end of the cleaning roller, with the two gears meshing with each other.

[0012] In one embodiment of this utility model, a third support frame is fixedly installed on the top of the base plate, a scraper and a limiting post are fixedly installed in the inner cavity of the third support frame, a reciprocating screw is rotatably installed in the inner cavity of the third support frame, a cleaning plate is threadedly connected to the outer surface of the reciprocating screw, and the cleaning plate is slidably connected to the limiting post.

[0013] In one embodiment of this utility model, a first pulley is fixedly connected to one end of the gear, and a second pulley is fixedly connected to one end of the reciprocating screw. The first pulley and the second pulley are driven by a belt.

[0014] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0015] The present invention discloses a cross-belt sorting machine correction device, which drives the cleaning rollers to rotate via the output shaft of a motor. Through the meshing of two gears, both cleaning rollers begin to rotate on the surface of the conveyor belt, scraping off the garbage on the surface of the conveyor belt. Through belt drive, the first pulley drives the second pulley to rotate. The second pulley, in conjunction with the limiting post, limits the cleaning plate, allowing the cleaning plate to slide back and forth on one side of the scraper, scraping off the garbage on that side of the scraper, thereby cleaning the surface of the scraper and cleaning the surface of the conveyor belt, which can reduce the occurrence of conveyor belt deviation.

[0016] The present invention discloses a cross-belt sorting machine correction device. When the conveyor belt deviates, the threaded rod is rotated, causing the threaded rod to slide along the inner cavity of the chute. When the chute moves, the rotating rod rotates on the inner surface of the chute. The conveyor roller is slidably connected to the bearing, so the bearing causes the conveyor roller to deviate relative to the chute. At the same time, the chute moves together with the chute, carrying the bearing and the conveyor roller, to achieve the correction of the conveyor belt deviation. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] Reference Figure 1-5 As shown, the present invention provides a cross-belt sorting machine correction device, including a base plate 1. A first support frame 2 is fixedly installed on the top of the base plate 1. Two conveyor rollers 3 are rotatably installed in the inner cavity of the first support frame 2. A conveyor belt 31 is wound around the outer surface of the two conveyor rollers 3. A slider 222 is rotatably connected to one end of the conveyor roller 3. A limit frame 22 is fixedly installed on one side of the first support frame 2. The slider 222 is slidably connected to the limit frame 22. A threaded rod 23 is rotatably connected to one side of the slider 222.

[0026] The inner cavity of the limiting frame 22 is provided with a sliding groove 221, and the slider 222 is slidably installed in the inner cavity of the sliding groove 221.

[0027] The slider 222 has a first rotating groove 2221 on one side, and two second rotating grooves 2222 are formed on the inner surface of the first rotating groove 2221.

[0028] A rotating rod 2223 is rotatably mounted on the inner surface of the second rotating groove 2222. The two rotating rods 2223 are fixedly connected to a bearing 223 on their opposite surfaces. One end of the conveying roller 3 is slidably mounted in the inner cavity of the bearing 223.

[0029] In the existing technology, the problem of belt misalignment is caused by the skewness of the belt roller.

[0030] When this utility model is in use, if the belt deviates, firstly, the threaded rod 23 is rotated. The threaded rod 23 is rotated in the direction the belt deviates. The threaded rod 23 is threadedly connected to the limiting frame 22. Therefore, rotating the threaded rod 23 can make the threaded rod 23 slide along the slider 222 and the bearing 223 in the inner cavity of the slide groove 221. At this time, the bearing 223 will deviate along the conveyor roller 3. After the conveyor roller 3 deviates, the conveyor belt 31 will also deviate along with the transmission roller 3. When the conveyor belt 31 deviates to a state where it is not deviated, the rotation of the threaded rod 23 is stopped. At this time, the conveyor belt 31 can rotate stably. The conveyor roller 3 and the slider 222 are respectively on the inner ring and outer ring of the bearing 223. One end of the conveyor roller 3 is fixedly connected to a motor, and the motor is fixedly connected to the first support frame 2.

[0031] In use, when the threaded rod 23 is rotated, the threaded rod 23 moves along with the slider 222. The rotating rod 2223 will rotate on the inner surface of the rotating groove 2222. The conveyor roller 3 is slidably connected to the bearing 223. Therefore, the bearing 223 will cause the conveyor roller 31 to deflect relative to the slider 222. At the same time, the slider 222 moves together with the bearing 223 and the conveyor roller 3 to achieve the correction of the conveyor belt 31.

[0032] Furthermore, such as Figure 5 As shown, a second support frame 4 is fixedly installed on the top of the base plate 1. Two cleaning rollers 41 are rotatably installed in the inner cavity of the second support frame 4, and one of the cleaning rollers 41 is fixedly connected to a motor 42 at one end.

[0033] The motor 42 is fixedly installed on one side of the second support frame 4, and a gear 43 is fixedly connected to one end of the cleaning roller 41, with the two gears 43 meshing with each other.

[0034] In order to prevent the conveyor belt 31 from shifting due to debris on its surface, this utility model requires cleaning the conveyor belt 31. During use, the output shaft of the motor 42 drives the cleaning roller 41 to rotate, and the gear 43 drives both cleaning rollers 41 to start rotating on the surface of the conveyor belt 31. This can remove the debris from the surface of the conveyor belt 31.

[0035] Furthermore, such as Figure 5 As shown, a third support frame 5 is fixedly installed on the top of the base plate 1. A scraper 51 and a limiting post 52 are fixedly installed in the inner cavity of the third support frame 5. A reciprocating screw 53 is rotatably installed in the inner cavity of the third support frame 5. A cleaning plate 54 is threadedly connected to the outer surface of the reciprocating screw 53. The cleaning plate 54 is slidably connected to the limiting post 52.

[0036] One end of the gear 43 is fixedly connected to a first pulley 44, and one end of the reciprocating screw 53 is fixedly connected to a second pulley 55. The first pulley 44 and the second pulley 55 are driven by a belt 56.

[0037] In use, this utility model enables the first pulley 44 and the second pulley 55 to rotate synchronously via the belt 56. The second pulley 55 drives the reciprocating screw 53 to rotate, and the limiting post 52 limits the cleaning plate 54, allowing the cleaning plate 54 to slide on one side of the scraper 51. This pushes the garbage scraped off by the scraper 51 to both sides of the conveyor belt 31 and drops it away from the conveyor belt 31, thus cleaning the surface of the conveyor belt 31.

[0038] Working principle: First, the output shaft of motor 42 drives the cleaning roller 41 to rotate. Through the meshing of two gears 43, both cleaning rollers 41 begin to rotate on the surface of conveyor belt 31, scraping off the garbage on the surface of conveyor belt 31. Through belt 56, the first pulley 44 drives the second pulley 55 to rotate. The second pulley 55, together with the limiting post 52, limits the cleaning plate 54, allowing the cleaning plate 54 to slide back and forth on one side of scraper 51, scraping off the garbage on one side of scraper 51, thereby cleaning the surface of scraper 51. Cleaning the surface of conveyor belt 31 can reduce the occurrence of conveyor belt 31 deviation.

[0039] When the conveyor belt 31 deviates, the threaded rod 23 is rotated, causing the threaded rod 23 to slide along the slider 222 in the inner cavity of the groove 221. When the slider 222 moves, the rotating rod 2223 will rotate on the inner surface of the groove 2222. The conveyor roller 3 is slidably connected to the bearing 223. Therefore, the bearing 223 will cause the conveyor roller 31 to deviate relative to the slider 222. At the same time, the slider 222 moves together with the bearing 223 and the conveyor roller 3 to achieve the correction of the conveyor belt 31.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
