Description

Technical Field

[0001] This application relates to the technical field of belt conveyors, and particularly to a cleaning device and a cleaning system for the belt of a belt conveyor. Background Art

[0002] As a common material conveying device, the belt conveyor plays a crucial role in industrial production. However, due to the different physical properties of materials, material dust often adheres to the surface of the conveyor belt, bringing many problems to the normal operation of the equipment. At the material dropping port, the original cleaning roller may not be able to thoroughly clean the belt, resulting in material dust entering the main and driven roller wheels and the lower supporting roller wheels in the no-load section. Once the surfaces of the main and driven roller wheels and the roller housing are contaminated with dirt, it will accelerate the wear and damage of the conveyor belt. At the same time, the entry of fine dust may also exacerbate the wear of the bearings of the main and driven roller wheels and the supporting roller wheels. In addition, the adhesion of dirt to the surface of the main and driven roller wheels may cause the conveyor belt to deviate, increasing wear and even tearing the surface of the conveyor belt, resulting in serious consequences. The cleanliness of the belt conveyor is crucial for the quality of industrial production products and the stable operation of the equipment.

[0003] In the related art, when cleaning the belt of a belt conveyor, usually two workers need to cooperate with each other. One worker uses a wet mop and fixes it on the belt surface by hand to prevent it from falling. At the same time, the other worker listens to the switch signal at the local switch position of the belt conveyor, washes the mop many times, and wipes repeatedly to clean the surface of the belt conveyor belt. Using a mop to clean and maintain the belt has the following problems: 1. The mop is not accurately positioned and wears the belt. The fixing frame of the mop strip has sharp parts, and improper positioning of the mop has the potential to damage the belt; 2. The working hours are long and the intensity is high. It takes a long time for two workers to wipe the belt of the belt conveyor, and the labor intensity is high; 3. There are quality and safety hazards. Due to mop wiping, there is a quality hazard that the mop strip may fall off, and there may be a situation of injuring people during the maintenance process. Summary of the Utility Model

[0027] As Figure 1 and Figure 2 shown, according to one aspect of the present application, the embodiment of the present application provides a cleaning device 100 for the belt of a belt conveyor 300. The cleaning device 100 includes two parallel, spaced and oppositely arranged mounting plates 10, a brush roller 20, two bearing seats 30, a linear drive mechanism 40 and a rotary drive mechanism 50. In combination with Figure 3, the cleaning device is mounted on the bracket of the belt conveyor 300 through two mounting plates 10. Through holes 11 penetrating the mounting plates 10 are formed at corresponding positions of the two mounting plates 10 to form an avoidance space for the movement of the brush roller 20. In this embodiment, the through hole 11 can be an oblong hole. The brush roller 20 is arranged between the two mounting plates 10. Two ends of the brush roller 20 respectively pass through the through holes 11 on the two mounting plates 10. Cleaning brushes for cleaning the belt are arranged on the brush roller 20 and are distributed along the axial direction of the brush roller 20. Two bearing seats 30 are respectively slidably arranged on the two mounting plates 10. The sliding direction of the bearing seats 30 on the mounting plates 10 is the same as the extending direction of the through holes 11. Two ends of the brush roller 20 are respectively rotatably connected to the two bearing seats 30. This arrangement enables the bearing seats 30 to drive the brush roller 20 to move along the extending direction of the through holes 11 in the through holes 11 when the bearing seats 30 slide on the mounting plates 10. The linear drive mechanism 40 is connected to the bearing seats 30 and is used to drive the bearing seats 30 to slide on the mounting plates 10 so as to further drive the brush roller 20 to move. The rotary drive mechanism 50 is connected to one end of the brush roller 20 and is used to drive the brush roller 20 to rotate in the bearing seats 30.

[0028] The cleaning device 100 and the cleaning system for the belt of the belt conveyor 300 provided by the embodiments of the present application, after the cleaning device 100 is mounted on the bracket of the belt conveyor 300 through the mounting plates 10, the brush roller 20 can be driven to rotate by the rotary drive mechanism 50, and then the bearing seats 30 can be driven to slide on the mounting plates 10 by the linear drive mechanism 40, so as to drive the cleaning brushes to move to the position in contact with the belt, and the cleaning brushes clean the belt. The cleaning device 100 and the cleaning system for the belt of the belt conveyor 300 provided by the embodiments of the present application have low design cost, simple structure, flexibility and strong applicability. The position of the brush roller 20 device can be adjusted according to the actual situation, solving the problems of long manual maintenance time, high labor intensity and quality hidden dangers. At the same time, the service life of the belt conveyor is prolonged, the maintenance working hours are saved, and the cleaning work efficiency is improved.

[0029] In some embodiments, the number of the linear drive mechanisms 40 is two. The two linear drive mechanisms 40 are respectively arranged on the two mounting plates 10, and the two linear drive mechanisms 40 are respectively connected to the two bearing seats 30. In this embodiment, by arranging the two linear drive mechanisms 40 to respectively drive the two bearing seats 30 to move, when the position of the brush roller 20 is adjusted, the two ends of the brush roller 20 can move synchronously without skew, so that the position adjustment of the brush roller 20 is more stable.

[0030] Such as Figure 5As shown, in some embodiments, the linear drive mechanism 40 is a cylinder, which includes a cylinder body 41 and a telescopic rod 42. The telescopic rod 42 is telescopically arranged on the cylinder body 41. The cylinder body 41 is connected to the mounting plate 10, and the telescopic rod 42 is connected to the bearing seat 30. The telescopic direction of the telescopic rod 42 is the same as the extending direction of the straight groove 11. In this embodiment, the bearing seat 30 is linearly driven by the cylinder, and the structure is simple. The cylinder in this embodiment can be a double-rod cylinder. When cleaning the belt, the two double-rod cylinders can be respectively located on both sides of the belt, and the two double-rod cylinders can be respectively fixed to the mounting plate 10 through cylinder brackets. Of course, in other embodiments, the linear drive mechanism 40 can also achieve linear drive through, for example, a linear motor, a rack and pinion structure, etc.

[0031] In some embodiments, the cleaning device 100 further includes an L-shaped mounting bracket 60. The linear drive mechanism 40 and the rotational drive mechanism 50 are respectively connected to two mutually perpendicular surfaces of the L-shaped mounting bracket 60. In this embodiment, the linear drive mechanism 40 can drive the rotational drive mechanism 50 to move by driving the L-shaped mounting bracket 60, and then drive the brush roller 20 and the bearing seat 30 to move through the rotational drive mechanism 50, thereby increasing the integration degree of the cleaning device 100 and reducing the volume of the cleaning device 100. At the same time, in this embodiment, the linear drive mechanism 40 supports the rotational drive mechanism 50 through the L-shaped mounting bracket 60, which can reduce the radial force borne by the brush roller 20 and avoid the possible radial deformation of the brush roller 20 caused by the linear drive mechanism 40 indirectly supporting the rotational drive mechanism 50 by directly supporting the bearing seat 30, increasing the service life of the cleaning device 100. Exemplarily, on the side of the cleaning device 100 where the rotational drive mechanism 50 is provided, the linear drive mechanism 40 can be directly connected to the L-shaped mounting bracket 60; on the side of the cleaning device 100 where the rotational drive mechanism 50 is not provided, the linear drive mechanism 40 can be directly connected to the bearing seat 30 on this side.

[0032] In some embodiments, the L-shaped mounting bracket 60 is further provided with reinforcing ribs, and the reinforcing ribs are perpendicularly connected to two mutually perpendicular surfaces of the L-shaped mounting bracket 60. In this embodiment, the strength of the L-shaped mounting bracket 60 is increased by setting the reinforcing ribs, so that the L-shaped mounting bracket 60 can reliably connect the linear drive mechanism 40 and the rotational drive mechanism 50.

[0033] As Figure 4As shown, in some embodiments, the rotation drive mechanism 50 includes a drive motor 51, and the output shaft of the drive motor 51 is in transmission connection with the brush roller 20. In some embodiments, the rotation drive mechanism 50 further includes a right-angle speed reducer 52. The output shaft of the drive motor 51 is connected to the input shaft of the right-angle speed reducer 52, and the output shaft of the right-angle speed reducer 52 is connected to the brush roller 20. The brush roller 20 is perpendicular to the output shaft of the drive motor 51. In this embodiment, by providing the right-angle speed reducer 52, the speed reduction from the motor to the brush roller 20 can be achieved. At the same time, the right-angle speed reducer can change the transmission direction of the power, which is beneficial to reducing the size of the brush roller 20 in the axial direction. In this embodiment, the double-rod cylinder can make the brush roller 20 reciprocate up and down to contact the belt through the compressed air gas circuit system, and the drive motor 51 drives the brush roller 20 to rotate through the right-angle speed reducer 52 to realize the operation of the entire device.

[0034] In some embodiments, the bearing seat 30 includes a bearing bracket and a bearing. The bearing is fixed on the bearing bracket, and the bearing bracket is connected to the linear drive mechanism 40. A chute is provided on the bearing bracket, and a slide rail 12 is formed on the mounting plate 10. The chute and the slide rail 12 cooperate with each other. In this embodiment, the sliding of the bearing seat 30 on the mounting plate 10 is realized through the above setting method. In this embodiment, the bearing can be a pillow block bearing. Two pillow block bearings can be respectively fixed on the left and right bearing brackets through countersunk head screws. The bearing bracket is inserted into the mounting plate 10 through the cooperation of the chute and the slide rail 12. To adapt to the different connection methods of the two linear drive mechanisms 40 on the left and right sides with the brush roller 20, the bearing brackets on the left and right sides of the cleaning device 100 can have different structures. For example, the bearing bracket on the left side can be L-shaped, and the bearing bracket on the right side can be straight plate-shaped.

[0035] In some embodiments, the cleaning brush is a hollow cylinder, and the cleaning brush is concentrically sleeved on the brush roller 20. End caps are provided at both ends of the cleaning brush, and the end caps are key-connected to the brush roller 20. In this embodiment, the cleaning brush can be a cylindrical brush. The cleaning brush with this structure is sleeved on the brush roller 20, which can have a larger cleaning area to cover the width direction of the belt. When cleaning the belt, the axial direction of the cleaning brush can be perpendicular to the conveying direction of the belt.

[0036] As Figure 6 shown, according to another aspect of the present application, an embodiment of the present application further provides a cleaning system for the belt of a belt conveyor 300. Brackets are respectively provided on both sides of the belt of the belt conveyor 300. The cleaning system includes the cleaning device 100 provided in any embodiment of the present application and a water spraying device 200. The two mounting plates 10 of the cleaning device 100 are respectively used for connecting with the brackets on both sides of the belt; the water spraying device 200 is used for being mounted on the bracket and spraying water on the belt.

[0037] Taking the cleaning system applied to the inclined long anti-slip belt conveyor 300 of the pneumatic silk drying machine in the cigarette making line as an example, the working principle of the cleaning system is described as follows: When the staff clean the belt conveyor 300, first, the staff start the belt conveyor 300 to make the belt run, then open the stop valve of the water spraying device 200, start the motor of the cleaning device 100, and the motor drives the brush roller 20 through mechanical transmission. Then, open the compressed air of the jacking cylinder in the double-rod cylinder, and the brush roller 20 rises to contact the belt. The nozzles of the water spraying device 200 spray water on the belt to soak the belt. The brush on the brush roller 20 cleans the soaked belt, and the nozzles of the water spraying device 200 spray the stains on the belt. The sewage during the cleaning process flows to the sewage tank 400 through the ash receiving plate of the belt conveyor 300, and the sewage is discharged into the sewer pipe through the drain port 500 of the sewage tank 400. The staff observe the cleaning degree of the belt of the belt conveyor 300. After the belt is clean, lower the brush roller 20 in sequence, stop the driving motor 51 of the brush roller 20, and close the valve of the water spraying device 200. The cleaning is completed.

[0038] The cleaning device and cleaning system provided by the embodiments of the present application can automatically clean the belt of the belt conveyor and are applicable to the cleaning work of the belt conveyors in each process of the cigarette making workshop. The cleaning ability of the cleaning device has a crucial impact on improving the operation efficiency and reliability of the belt conveyor, and can also significantly reduce the failure rate and maintenance cost of the conveying auxiliary equipment. By optimizing the cleaning device, not only can the service life of the conveyor belt, the main and driven roller wheels, the idler wheels, etc. be extended, but also the downtime and maintenance workload can be reduced, and the overall production efficiency can be improved. The device has a simple structure, is easy to maintain, has good stability, a high safety factor, a high cleaning efficiency, and a wide application range.
