Description

Technical Field

[0001] This application relates to the field of conveyor belt cleaning technology, and in particular to a conveyor belt cleaning machine. Background Technology

[0002] In waste management, conveyor belts are widely used as core equipment for material transport. However, over long-term use, a large amount of contaminants, such as garbage debris, oil, dust, and sticky impurities, easily accumulate on the surface of the conveyor belt. These residual contaminants not only breed bacteria and produce odors, affecting the hygiene and safety of the working environment, but may also cause material slippage due to changes in the coefficient of friction, reducing transport efficiency. At the same time, the long-term accumulation of contaminants accelerates the wear of the conveyor belt, shortens its service life, and increases equipment maintenance costs and the frequency of downtime for repairs.

[0003] Existing conveyor belt cleaning equipment has many limitations: some equipment only uses a single physical wiping or spraying method, which has limited cleaning effect and is difficult to remove stubborn stains; the fit between some equipment and the conveyor belt is not adjustable, resulting in poor compatibility with different models and tensions of conveyor belts, and problems such as missed cleaning or excessive friction damage to the conveyor belt are easy to occur during cleaning; and the cleaning components (such as rollers and scrapers) are prone to residual dirt, affecting the continuous cleaning ability.

[0004] Therefore, there is an urgent need for a conveyor belt cleaning device that integrates multiple cleaning methods, is highly adaptable, and can efficiently remove and discharge dirt. Utility Model Content

[0005] To address the aforementioned problems, this application provides a conveyor belt cleaning machine.

[0006] The conveyor belt cleaning machine provided in this application adopts the following technical solution: A conveyor belt cleaning machine includes: a cleaning loading body fixed below the conveyor belt for supporting various components and providing cleaning operation space; a conveyor belt bonding frame adapted to and connected to the conveyor belt for cooperating with the equipment; a cleaning roller disposed at the upper center of the cleaning loading body and in contact with the surface of the conveyor belt; and a foreign matter scraper located on one side of the cleaning roller for scraping off residual dirt on its surface during the operation of the cleaning roller. The cleaning roller physically cleans the surface of the conveyor belt during its movement. The bonding tension of the conveyor belt bonding frame is adjustable.

[0007] Preferably, it also includes: a high-pressure spraying component, which sprays and removes dirt from the surface of the conveyor belt and the cleaning rollers, and can be introduced with a cleaning liquid that has a dirt-removing function to enhance the cleaning effect.

[0008] Preferably, the cleaning loading body includes a box and a discharge port, the discharge port is located at the bottom of the box and connected to a negative pressure suction pipe, and the cleaning roller is rotatably mounted on the upper end of the box.

[0009] Preferably, the conveyor belt bonding frame includes a bonding main frame, the bonding main frame is provided with a cleaning port adapted to the edge of the conveyor belt, and the upper center of the bonding main frame is set as a plane, gradually inclined towards both ends.

[0010] Preferably, the foreign matter scraping component includes: a scraping support frame fixed to the cleaning device on the main body and having an adjustable scraping angle, and a scraping contact component disposed outside the scraping support frame and in contact with the surface of the cleaning roller component.

[0011] Preferably, the high-pressure spray component includes: a spray pipe connected to an external liquid supply device; multiple nozzles arranged at equal intervals along the spray pipe and facing the conveyor belt surface and the cleaning roller; a drive component connected to one end of the spray pipe and driving the spray pipe to adjust its angle; and a load-bearing component connected to the other end of the spray pipe via a flange to ensure the working stability of the spray pipe.

[0012] In summary, this application includes the following beneficial technical effects: By combining physical friction cleaning of the cleaning rollers, high-pressure water rinsing of the high-pressure spray components, scraping of residual dirt by the foreign object scraper, and immediate sewage discharge by negative pressure suction, a complete cleaning loop of "wiping-spraying-scraping-suction" is formed. This effectively removes various types of dirt such as dust, oil, and sticky impurities from the surface of the conveyor belt, and is particularly effective in removing stubborn stains.

[0013] The high-pressure spray component can simultaneously clean the surface of the cleaning roller component, while the foreign matter scraper component can scrape off residual dirt from the roller component in real time, avoiding contamination of the cleaning components themselves and reducing the cleaning effect, extending the continuous working time of the equipment, and reducing the frequency of downtime maintenance.

[0019] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0020] This application discloses a conveyor belt cleaning machine. (Refer to...) Figure 1 The system includes: a cleaning loading body 1, a conveyor belt bonding frame 2, a cleaning roller component 3, a foreign object scraping component 4, and a high-pressure spray component 5. The cleaning loading body 1 is fixed under the conveyor belt, supporting all cleaning components and providing sufficient working space to ensure smooth cleaning. During actual assembly, the cleaning loading body 1 is fixed to the side frame of the conveyor belt using a bracket; either a U-shaped or L-shaped bracket can be used. The conveyor belt bonding frame 2 is adapted to the conveyor belt, ensuring proper fit between the cleaning equipment and the conveyor belt. The adjustable tension function of the conveyor belt bonding frame 2 allows for precise adjustment based on the actual condition of the conveyor belt (such as tension and material). Adjustments are made during assembly by stretching the conveyor belt bonding frame 2 upwards to a suitable distance and then fixing its position with bolts. This further ensures the adjustability of the overall installation if the cleaning loading body 1 and the bracket are not tightly bonded to the conveyor belt after installation. The adjustable tension ensures that the cleaning roller component 3 maintains optimal contact with the conveyor belt surface, avoiding excessive looseness or tightness and guaranteeing the cleaning effect. The cleaning roller 3 is installed at the upper center of the cleaning loading body 1, in contact with the surface of the conveyor belt. During the conveyor belt's movement, the cleaning roller 3 cleans the surface through physical friction, removing accumulated dust and dirt. The cleaning roller 3 has sufficient wear resistance to withstand prolonged cleaning operations and is not easily damaged. A foreign matter scraper 4 is located on one side of the cleaning roller 3 to scrape away residual dirt from its surface. The scraper ensures that the cleaning roller 3 is not covered by excessive dirt, thus avoiding affecting the cleaning effect. The foreign matter scraper 4 must ensure that it will not damage the conveyor belt or the cleaning roller, while also possessing good wear resistance.

[0021] In the above embodiments, furthermore, to ensure comprehensive cleaning, when the surface oil residue has dried severely, the unilateral brush of the cleaning roller 3 cannot completely clean it. In this case, a high-pressure spray unit 5 is installed inside the cleaning loading body 1. The high-pressure spray unit 5 and the foreign matter scraper 4 are symmetrically arranged along the cleaning roller 3. The high-pressure spray unit 5 sprays high-pressure water jets to clean the conveyor belt surface and the cleaning roller 3. The impact of the high-pressure water jets effectively removes surface-attached dirt, dust, or oil stains. In actual use, in addition to using ordinary water, the high-pressure spray unit 5 can also be further improved by introducing a cleaning fluid containing decontamination properties. The cleaning fluid typically contains detergents that can break down grease, sticky substances, or other stubborn stains, ensuring comprehensive and deep cleaning. The high-pressure spray unit 5 not only cleans the conveyor belt surface but also cleans the cleaning roller 3, ensuring that the roller is not covered by dirt and maintaining its cleanliness.

[0022] In actual use, during conveyor belt operation, the cleaning device physically cleans the conveyor belt surface through the contact of the cleaning rollers 3, removing attached dirt. Simultaneously, a negative pressure suction structure is installed externally on the main cleaning unit 1. This structure utilizes existing equipment to quickly remove residual dirt from the surface, ensuring thorough cleaning. A high-pressure spray system further removes stubborn stains by rinsing the conveyor belt surface. The spray system can typically incorporate cleaning liquid to enhance cleaning effectiveness, especially for oil stains or highly viscous dirt. During the cleaning process, the high-pressure spray unit 5 works in conjunction with the cleaning rollers 3. Cleaning liquid is sprayed onto the conveyor belt surface, while the rollers remove dirt through physical friction. The high-pressure spray unit 5 not only cleans the conveyor belt surface but also sprays onto the cleaning rollers 3, ensuring these components are not covered in dirt during operation. Through a combination of methods including liquid spraying and scraping, a comprehensive cleaning is achieved.

[0023] like Figure 1 and Figure 2 As shown, the cleaning loading body 1 includes a box body 11 and a discharge port 12. The box body 11 serves as the main load-bearing part of the cleaning loading body 1, accommodating components such as the cleaning roller 3, the foreign matter scraper 4, and the high-pressure sprayer 5, providing overall structural support. The discharge port 12 is located at the bottom of the box body 11 and is used to discharge the cleaned dirt and debris. The discharge port 12 is connected to a negative pressure suction pipe, ensuring that dirt generated after surface cleaning can be quickly discharged, avoiding accumulation and blockage. The negative pressure suction pipe utilizes negative pressure suction to quickly discharge dirt, ensuring that the cleaning area remains clean at all times.

[0024] like Figure 2As shown, the conveyor belt bonding frame 2 includes a bonding main frame 21 and a cleaning port 22. The bonding main frame 21 ensures a tight fit between the cleaning equipment and the conveyor belt. By adjusting the contact position with the conveyor belt, it ensures good contact between the cleaning rollers 3, sprayers, scrapers, and other components and the conveyor belt surface, thereby improving the cleaning effect. The cleaning port 22 is located on the bonding main frame 21 and is adapted to the edge of the conveyor belt. The cleaning port 22 ensures that the cleaning fluid, detergent, or water flow can effectively contact the edge of the conveyor belt surface, helping to remove dirt from the edges.

[0025] In the above embodiments, further, as Figure 3 As shown, the upper center of the main frame 21 is set as a plane, gradually sloping towards both ends. The flat design ensures effective contact of the cleaning device at the center of the conveyor belt, while the sloping ends help guide excess dirt to the cleaning port 22, preventing dirt from accumulating on both sides and facilitating the smooth flow and discharge of cleaning fluid and dirt. The sloping structure helps the wastewater or cleaning fluid generated during the cleaning process flow to the discharge port 12, ensuring that dirt does not remain inside the equipment and reducing secondary pollution.

[0026] like Figure 1 As shown, the foreign matter scraping component 4 includes a scraping support frame 41 and a scraping contact component 42. The scraping support frame 41 is fixed to the cleaning loading body 1. By adjusting the scraping angle, the scraping force and scraping method can be adjusted according to different dirt conditions or conveyor belt conditions. The scraping contact component 42 is located outside the scraping support frame 41 and contacts the surface of the cleaning roller component 3, and can scrape off residual dirt from the surface of the cleaning roller component 3. Since a certain amount of dirt accumulates on the surface of the cleaning roller component 3, the scraping contact component 42 can effectively clean away this dirt and prevent it from affecting subsequent cleaning work. The scraping contact component 42 needs to be elastic and wear-resistant to ensure that it will not be damaged during long-term operation, while effectively removing dirt.

[0027] like Figure 2 As shown, the high-pressure spray unit 5 includes: a spray pipe 51, nozzles 52, a drive unit 53, and a carrier 54. The spray pipe 51 delivers cleaning fluid (or water) supplied by an external liquid supply device to the nozzles 52. Multiple nozzles 52 are evenly spaced along the spray pipe 51, each spraying towards the conveyor belt surface and the cleaning roller 3. The drive unit 53 is connected to one end of the spray pipe 51, driving the spray pipe 51 to adjust its angle. This allows the spray pipe 51 to adjust its angle according to different needs during the cleaning process, ensuring that the nozzles 52 can more accurately cover the cleaning area. Angle adjustment improves the coverage of the spray liquid, especially when dealing with the edges of the conveyor belt or areas that are difficult to clean, providing flexibility and efficiency. The carrier 54 is connected to the other end of the spray pipe 51 via a flange, ensuring that the spray pipe 51 remains stable during operation.
