[0026] Example
[0027] In existing technologies, powdery or lumpy materials may remain on the roller conveyor during the transport of goods. If these materials remain on the roller surface for a long time, they will contaminate the next transport and increase the wear of the conveyor roller during operation. This not only poses a safety hazard to the materials but also causes property damage to the equipment.
[0028] Please see Figure 1-7 This utility model provides a technical solution: a conveyor structure that is easy to clean, including a support frame 1, a fixed frame 12, a motor 13, a main shaft 14, a rotating shaft 15, and a conveyor frame 5. The support frame 1 and the fixed frame 12 are both located outside the conveyor frame 5. Inside the conveyor frame 5, two chain belts 11 are slidably connected by a guide rail. The guide rail is a closed-loop structure with guide grooves, and the side of the chain belt 11 is slidably inserted into the guide groove of the guide rail. A roller 10 is connected between the two chain belts 11. A motor 13 is installed on one side of the fixed frame 12. The output end of the motor 13 is fixedly connected to the main shaft 14. Turntables 16 are fixedly sleeved on the outside of both the main shaft 14 and the rotating shaft 15. Three drive wheels 17 are fixedly connected to the outside of the turntables 16. The drive wheels 17 adopt a three-blade design (e.g., Figure 7 As shown), the entire system is driven by the rotation of three paddles pushing the rollers 10. The drive wheel 17 adopts a downward design, so that the rollers 10 driven by the paddles are located at the lower part of the conveyor frame 5, thereby ensuring that the paddles do not extend beyond the upper roller 10 group used for conveying items, thus avoiding the paddles from affecting the transportation. The rotating shaft 15 is rotatably connected to the inside of the fixed frame 12 through bearings. The drive wheel 17 is located between the rollers 10. The conveyor cleaning assembly 2 is provided inside the support frame 1.
[0029] The conveyor cleaning assembly 2 includes a first guide plate 21, a second guide plate 22, a third guide plate 23, a conduit 210, a horizontal pipe 24, a first water pump 29, a water tank 3, and a funnel 27. The funnel 27 is fixedly connected to the inside of the support frame 1. The first guide plate 21, the second guide plate 22, and the third guide plate 23 are sequentially installed inside the support frame 1. Each of the first guide plate 21, the second guide plate 22, and the third guide plate 23 has a guide groove 26 inside, which guides the water inside the first guide plate 21, the second guide plate 22, and the third guide plate 23. The top of the spray nozzle 25 is opposite to the first guide plate 21. The first guide plate 21 and the third guide plate 23 are located above the second guide plate 22, and the funnel 27 is located below the third guide plate 23. The water sprayed from the spray nozzle 25 passes through the roller 10 and then rushes into the first guide plate 21, flowing along the first guide plate 21 towards... After passing through roller 10 for the second time, the water falls into the second guide plate 22. Similarly, it passes through roller 10 and flows into the third guide plate 23. At this time, the kinetic energy of the water flow decreases, and it falls downward, rinsing roller 10 again. The dirty water falls into the funnel 27. The bottom of the funnel 27 is connected to the water tank 3 through the conduit 210. The support frame 1 is fixedly connected to the base 6. The water tank 3 is fixedly connected to the top of the base 6. The base 6 supports the water tank 3. A second water pump 8 is provided on one side of the water tank 3. The bottom of the second water pump 8 is fixedly connected to the fixing rod 9. The fixing rod 9 supports the second water pump 8. The bottom of the fixing rod 9 is fixedly connected to the top of the base 6. The inlet pipe of the second water pump 8 is connected to the conduit 210 through a pipe. The outlet pipe of the second water pump 8 is connected to the water tank 3 through a pipe. The second water pump 8 injects water from the conduit 210 into the water tank 3 through the pipe.
[0030] The first water pump 29 is fixedly installed on the top of the water tank 3. The inlet pipe of the first water pump 29 is connected to the water tank 3 through a pipe, and the outlet pipe of the first water pump 29 is connected to the horizontal pipe 24 through a pipe. The first water pump 29 injects water from the water tank 3 into the interior of the horizontal pipe 24 through the pipe. Seven spray nozzles 25 are connected to the upper surface of the horizontal pipe 24. A bracket 7 is fixedly connected to the lower surface of the horizontal pipe 24. The lower surface of the bracket 7 is fixedly connected to the upper surface of the water tank 3. The bracket 7 provides support and fixation for the horizontal pipe 24. A filter screen 28 is fixedly connected inside the funnel 27, and an air knife 4 is fixedly installed inside the support frame 1.
[0031] Working principle or structural principle: Goods are placed on rollers 10 on the surface of conveyor frame 5. Motor 13 drives turntable 16 to rotate via main shaft 14. As turntable 16 rotates, it drives three drive wheels 17 to rotate. Drive wheels 17 are located between rollers 10. As drive wheels 17 rotate, they push rollers 10 to move, thereby driving the entire chain belt 11 to move, realizing the conveying of goods. When rollers 10 move with chain belt 11 above water spray nozzles 25, the first water pump 29 and the second water pump 8 are started. Water in water tank 3 is drawn by the first water pump 29 and injected into horizontal pipe 24 under high pressure. It is then sprayed obliquely upward through water spray nozzles 25 connected to the upper surface of horizontal pipe 24, which provides the first high-pressure water cleaning for the conveying rollers 10, cleaning the rollers. Stubborn residues on the surface of roller 10 are washed away by high pressure, and the water flow enters the first guide plate 21 above. It is sprayed downward along the guide groove 26 and then cleans roller 10 for the second time. The water flow enters the second guide plate 22 and, similarly, flows upward along the guide groove 26, passes through roller 10 and enters the third guide plate 23. At this time, the kinetic energy of the water flow decreases and falls downward, rinsing roller 10 again to prevent dirt residue. The dirty water falls into the funnel 27, is filtered by the filter screen 28 and flows into the conduit 210. It is then sent to the water tank 3 by the second water pump 8 for recycling. After rinsing, roller 10 moves above the air knife 4. The air knife 4 uses high pressure to dry the wet roller 10, thus cleaning the conveyor roller 10.
[0032] The air outlet of the air knife 4 is located 8-12cm below the roller 10. The filter screen 28 should be regularly maintained and cleaned; if damaged, it should be removed and replaced promptly. The guide vane is tilted to the right at an angle of 45-60 degrees.
[0033] In summary, the first water pump 29 injects high-pressure water into the horizontal pipe 24, and the high-pressure water jet at the nozzle 25 cleans the roller 10. The roller 10 is repeatedly rinsed by the first guide plate 21, the second guide plate 22, and the third guide plate 23. Finally, the dirty water falls into the funnel 27, is filtered, and then recycled, achieving wastewater reuse and saving water. The roller 10 is rinsed four times in a timely manner, preventing powdery or lumpy materials from remaining on its surface, resulting in a more thorough cleaning. The first water pump 29 is model ZDK-1100W, the second water pump 8 is model ZP-LDCSB-001, and the motor 13 is model YX3-80M1-2. The manufacturer is Taizhou Xinling Electromechanical Co., Ltd.
