Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and particularly relates to a conveyor belt cleaning device and a belt conveyor device. Background Art

[0002] As the tobacco industry continues to improve its requirements for product processing technology and environmental specifications, the standards for equipment and environmental hygiene in the production process have been raised to the same level as those in the food processing field. However, the conveyor belt surface of the belt conveyor is easily contaminated by the conveyed materials, causing the belt surface to become sticky and dirty, making it difficult to clean and maintain, forming a source of pollution and having a significant impact on product quality.

[0003] Belt conveyors on silk production lines primarily connect the various processes. Some processes produce work-in-progress (WIP) materials that are high-temperature, high-humidity. As these materials are transported along the conveyor, they adhere to the belt surface, forming dirt. If not cleaned promptly, this dirt accumulates and forms crusts. This dirt then travels along with the material to the next process, creating a new source of contamination and negatively impacting product quality.

[0004] Currently, in tobacco factories, wet cleaning is commonly used to remove stains from conveyor belts. This involves manually cleaning the belt surface with a wet mop or rag. The hot water used is at a temperature of 50-60°C, which is effective in softening tobacco stains and is a temperature that is tolerable to the human body without causing any harm. However, this method has low cleaning efficiency and requires wetting the conveyor belt surface with hot water before each cleaning, which poses certain safety risks. Some conveyor belts are located high above the ground, posing a safety hazard of falling from height during operation.

[0005] Chinese patent CN202110467460.5 discloses a belt conveyor belt cleaning device, including a conveyor belt and a cleaning trolley of a belt conveyor. A scraper cleaning device and a brush cleaning device are sequentially provided on the trolley workbench along the direction of travel of the conveyor belt. The scraper cleaning device includes a scraper bracket, a first cylinder, a spring, and a scraper. The scraper cleaning device cleans large pieces of material adhering to the belt, and the brush cleaning device cleans fine particulate material on the belt. However, the cleaning device is separated from the conveyor belt and still requires manual operation, making it impossible to clean online. In addition, the brush cleaning device is not suitable for conveying materials with strong adhesion, such as tobacco and tobacco dirt.

[0006] Therefore, providing a better conveyor belt online cleaning device is a technical problem that needs to be solved urgently in this field. Utility Model Content

[0007] In view of the existing phenomenon, the technical problem to be solved by the present invention is to provide a conveyor belt cleaning device, which is particularly suitable for a belt conveyor device in tobacco shred production, and at least solves one of the above technical problems.

[0008] The technical solution provided in this application is a conveyor belt cleaning device, which is arranged on a belt conveyor device including a conveyor belt. The conveyor belt cleaning device includes: a fixing unit for connecting the belt conveyor device, and a scraper unit and a cleaning roller unit connected to the fixing unit and arranged in sequence along the conveying direction of the belt conveyor device; the scraper unit includes a scraper for contacting and cleaning the conveyor belt; the cleaning roller unit includes a cleaning roller that can roll in contact with and clean the conveyor belt.

[0009] In some embodiments, the fixing unit includes a fixing plate, a connecting column is fixedly connected to the fixing plate, a movable plate is slidably provided on the connecting column, and the movable plate and the fixing plate can be clamped and fixed to the belt conveyor device.

[0010] In some embodiments, the fixing unit further includes a protection plate fixedly disposed on an end of the connecting column away from the fixing plate.

[0011] In some embodiments, the relative distance between the scraper unit and the conveyor belt is adjustable.

[0012] In some embodiments, the scraper unit includes: a scraper frame connected to the fixing unit and used for mounting the scraper, and the scraper is provided with a strip hole for screwing with the scraper frame.

[0013] In some embodiments, the scraper includes a straight surface and an inclined surface, and the straight surface and the inclined surface form an angle of 20 degrees to 60 degrees for contacting and cleaning the conveyor belt.

[0014] In some embodiments, the scraper is made of rubber or plastic.

[0015] In some embodiments, a protruding cleaning strip is provided on the outer periphery of the cleaning roller.

[0016] In some embodiments, a slag receiving unit is provided at the conveying end of the conveyor belt.

[0017] Another technical solution provided by the present application is a belt conveyor device, including the aforementioned conveyor belt cleaning device.

[0018] The beneficial effects of this application are at least:

[0019] The conveyor belt cleaning device provided by the present application can be fixed to the belt conveyor device through a fixing unit, so as to automatically clean the conveyor belt through the movement of the conveyor belt itself, greatly reducing the production downtime caused by cleaning operations. The present cleaning device can work continuously to ensure the cleaning effect and product quality. When it is set on the lower side of the conveyor belt, it can be cleaned online without interrupting the production line, thereby improving the overall production efficiency. The present application sequentially arranges a scraper unit and a cleaning roller unit to form two-step cleaning of the conveyor belt consisting of a scraper and a cleaning roller, which can more effectively remove high-temperature and high-humidity material residues on the conveyor belt. The scraper first removes large pieces of adhesion, reducing the burden on subsequent cleaning steps; the cleaning roller further removes fine particles and stains to ensure that the surface of the conveyor belt is thoroughly cleaned, thereby avoiding pollutants from being brought into the next process and ensuring the purity and quality of tobacco or other products.

[0020] This cleaning device eliminates the need for workers to directly participate in cleaning operations, especially for conveyor belts at heights. This avoids the safety hazards associated with high-altitude operations and reduces the probability of industrial accidents. It also reduces the need for direct manual manipulation of hot water resources, lowering the risk of accidental burns. It is more economical and efficient than manual cleaning with random water dipping, reducing the waste of water resources and detergents. In the long run, this will significantly reduce production costs, reduce the amount of wastewater generated during the cleaning process, and provide a more effective waste collection and treatment mechanism, helping to achieve environmental value and reduce environmental impact. Furthermore, regular and effective cleaning can effectively extend the service life of conveyor belts and their related components, reduce equipment wear and failure due to dirt accumulation, and lower maintenance and replacement costs.

[0031] like Figure 1-2Embodiment 1 provides a conveyor belt cleaning device, which is arranged on a belt conveyor device including a conveyor belt. The conveyor belt cleaning device includes: a fixing unit 1 for connecting the belt conveyor device, and a scraper unit 2 and a cleaning roller unit 3 connected to the fixing unit 1 and arranged in sequence along the conveying direction of the belt conveyor device; the scraper unit 2 includes a scraper 21 for contacting and cleaning the conveyor belt; the cleaning roller unit 3 includes a cleaning roller 31 that can roll in contact with and clean the conveyor belt.

[0032] The conveyor belt cleaning device provided in the present application can be fixed to the belt conveyor device through the fixing unit 1, so as to automatically clean the conveyor belt through the movement of the conveyor belt itself, thereby reducing the production downtime caused by the cleaning operation. The present cleaning device can work continuously to ensure the cleaning effect and product quality. When it is arranged on the lower side of the conveyor belt, it can be cleaned online without interrupting the production line, thereby improving the overall production efficiency. The present application sequentially arranges the scraper unit 2 and the cleaning roller unit 3, and forms two step-by-step cleanings of the conveyor belt consisting of the scraper 21 and the cleaning roller 31, which can more effectively remove the material residues on the conveyor belt, especially the high-temperature and high-humidity material residues. The scraper 21 first removes the large pieces of adhesion, and the cleaning roller 31 further removes the fine particles and stains, ensuring that the surface of the conveyor belt is thoroughly cleaned, thereby ensuring the purity and quality of the tobacco or other products.

[0033] This cleaning device eliminates the need for workers to directly participate in cleaning operations, especially for conveyor belts at heights. This avoids the safety hazards associated with high-altitude operations and reduces the probability of industrial accidents. It also reduces the need for direct manual manipulation of hot water resources, lowering the risk of accidental burns. It is more economical and efficient than manual cleaning with random water dipping, reducing the waste of water resources and detergents. In the long run, this will significantly reduce production costs, reduce the amount of wastewater generated during the cleaning process, and provide a more effective waste collection and treatment mechanism, helping to achieve environmental value and reduce environmental impact. Furthermore, regular and effective cleaning can effectively extend the service life of conveyor belts and their related components, reduce equipment wear and failure due to dirt accumulation, and lower maintenance and replacement costs.

[0034] In this embodiment, the fixed unit 1 includes fixed plates 11, with connecting posts 12 fixedly connected between them. A movable plate 13 is slidably mounted on the connecting posts 12. The movable plate 13 and the fixed plates 11 can be clamped and fixed to the belt conveyor. The movable plate 13 can slide along the connecting posts 13 to move closer to or further away from the fixed plates 11. By flexibly positioning the fixed unit 1, the fixed unit 1 can be adapted for use with belt conveyors of varying widths. In this embodiment, locking bolts are also provided on the sides of the movable plate 13 and the fixed plate 11 to secure their relative position. These locking bolts are locked by abutting against one of the connecting posts 12.

[0035] In this embodiment, the fixing unit 1 further comprises a protective plate 14 fixedly mounted on the end of the connecting post 12 away from the fixing plate 11. The protective plate 14 can prevent the connecting post 12 from being exposed and causing accidents, and also protects the connecting post 12, making its installation more stable and reliable.

[0036] In this embodiment, the relative distance between the scraper unit 2 and the conveyor belt is adjustable. This allows the distance between the scraper 21 and the conveyor belt to be adjusted during use to ensure that the scraper 21 effectively removes dirt. The adjustability of the scraper 21 also eliminates errors caused by installation precision.

[0037] Specifically, the scraper unit 2 includes a scraper frame 22 connected to the fixing unit 1 for mounting the scraper 21. The scraper 21 is provided with a strip hole 211 for screwing to the scraper frame 22. The scraper 21 can be screwed to the scraper frame 22 at different positions in the strip hole 211 to adjust the relative distance between the scraper 21 and the conveyor belt. Furthermore, this embodiment also includes an adjustment bolt 221 for adjusting the position. Rotating the adjustment bolt 221 can move the scraper 21 closer to or farther from the scraper frame 22. Using the adjustment bolt 221 to adjust the relative position is safer, more stable, more precise, and more efficient.

[0038] like Figure 2 In this embodiment, the scraper 21 includes a straight surface and an inclined surface, and the straight surface and the inclined surface form an angle of 60 degrees for contacting and cleaning the conveyor belt. In other embodiments, the cleaning effect and structural strength are more balanced when the angle is set to 20 degrees to 60 degrees.

[0039] In this embodiment, the scraper 21 is made of plastic. In other embodiments, the scraper 21 can be made of rubber or plastic. Rubber or plastic materials have good cleaning effect and structural strength, which can meet the use requirements of the scraper 21.

[0040] like Figure 1 In this embodiment, the cleaning roller 31 is fixedly connected to the scraper frame 22 via a mounting post 32. A protruding cleaning strip 33 is provided on the outer periphery. During the rolling process of the cleaning roller 31, the cleaning strip 33 can increase the friction force, so that the soot scraped off or loosened by the scraper 21 can be further removed from the conveyor belt; the side of the cleaning strip 33 can guide the dirt away from its original position, reducing adhesion; the outer edge of the cleaning strip 33 itself also has a certain scraping effect. Figure 3 Furthermore, the cleaning strip 33 in this embodiment is spiral-shaped, and the scraping direction of its edge always forms an angle with the moving direction of the conveyor belt, making it easier to scrape off the soot. The scraped soot is loosened by rolling in the gaps between the cleaning strips 33 and then falls or is guided to the end of the cleaning roller 31. In other embodiments, the cleaning strip 33 can also be set to other shapes that have a cleaning effect.

[0041] In this embodiment, a slag collecting unit is further included at the conveying end of the conveyor belt, which is used to collect the scraped soot and other dirt.

[0042] Example 2 is a belt conveyor device, which is equipped with the conveyor belt cleaning device of Example 1 and includes all of its features and therefore also has all of its beneficial effects.
