Description

Technical Field

[0001] This invention relates to the field of cleaning and drying technology, specifically to a tray-turning cleaning and drying device suitable for explosion-proof dust environments. Background Technology

[0002] Currently, most dust explosion-proof cleaning devices on the market use top and bottom spray cleaning systems. However, due to limitations in spray angle and water flow coverage, blind spots easily form in workpiece corners and crevices, making it difficult to achieve the required cleanliness in a single cleaning cycle. Production sites typically rely on multiple cleaning cycles to compensate for these defects, resulting in wasted water, cleaning agents, and electricity. This also prolongs the time workpieces remain at the cleaning station, leaving a large amount of residual liquid on the workpiece surface and directly increasing the processing load on downstream drying equipment.

[0003] Meanwhile, existing equipment often uses recessed trays, whose recessed structure easily accumulates cleaning waste liquid. Once inside the drying zone, airflow is obstructed, hot air struggles to reach the liquid-accumulated areas, and moisture evaporation is insufficient. After drying, water stains easily remain on the workpiece and tray surface. These water stains, mixed with trace amounts of dust, easily form stubborn stains, affecting the cleaning effect. Furthermore, the residual moisture continuously carries into the drying system, further increasing the energy burden on the drying unit and reducing the overall efficiency of the automated production line. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention proposes a material tray flipping cleaning and drying device suitable for explosion-proof dust environments. The device employs a process of first flipping and inverting the material tray body, cleaning and drying it, and then flipping it back to its original position. This effectively cleans the hazardous chemical dust accumulated in the grooves of the material tray body, achieving a high degree of cleanliness. Furthermore, the entire process is automated and continuous, with smooth process connections.

[0054] like Figure 13 As shown, a second lifting assembly 46 is provided below the fourth housing 42. There are two second lifting assemblies 46, which are respectively located at both ends of the conveying direction of the fourth conveying assembly 43.

[0055] like Figure 16As shown, the second lifting assembly 46 includes a second lifting block 461, a second lifting plate 462, a second lifting base plate 464, a second lifting cylinder 463, and a second lifting guide rod 465. The second lifting block 461 and the second lifting plate 462 are disposed within the fourth housing 42. Two second lifting blocks 461 are provided, each positioned at one end of the second lifting plate 462. Each second lifting block 461 can fit over the convex shafts 53 on both sides of the end of the tray body 5. The second lifting base plate 464 is disposed on the bottom wall of the fourth housing 42. The second lifting cylinder 463 and the second lifting guide rod 465 are disposed on the second lifting base plate 464 and extend into the fourth housing 42. The ends of the second lifting cylinder 463 and the second lifting guide rod 465 are connected to the bottom of the second lifting plate 462.

[0056] like Figure 17 As shown, a rotating shaft 51 is provided at each end of the material tray body 5, i.e., on the two sides perpendicular to the conveying direction. The rotating shaft 51 is located at the midpoint of the end of the material tray body 5. Two convex shafts 53 are provided at each end of the material tray body 5, i.e., on the two sides parallel to the conveying direction. One protrusion 52 is provided on each side of the material tray body 5, i.e., on the two sides parallel to the conveying direction. One protrusion 52 is located at the midpoint of the side of the material tray body 5.

[0057] Specific implementation process: When the material tray body 5 is conveyed into the flipping pre-cleaning mechanism 1, after the sensor detects the arrival signal of the material tray body 5, the first blocking cylinder 153 at the front end of the flipping station extends and raises the first blocking block 151 to limit it; after the material tray has completely entered the interior of the interval, the inlet sealing cylinder 123 extends outward and the sealing plate 121 moves downward to block the opening of the first box 12 on the side of the material inlet direction, so as to achieve complete sealing of the equipment inlet channel.

[0058] At this time, the first spray head 172 and the rotating spray head 173 in the pre-cleaning mechanism start synchronously to thoroughly wet and rinse the surface of the tray body 5. When the tray body 5 is conveyed to the limit position of the first blocking component 15, the servo motor stops working and the first conveying component 13 stops operating. Then, the first lifting cylinders 163 on both sides lift synchronously from the front and rear ends of the tray body 5, and the first lifting block 161 raises the tray body 5 to the flipping operation height. The first push-pull cylinders 143 on both sides extend respectively, so that the first rotating fixing sleeves 142 at the front and rear are precisely aligned and connected with the rotating shaft 51 of the tray body 5. After the connection is completed, the first lifting cylinders 163 descend and reset, and the first rotating cylinder 141 drives the tray body 5 to complete a 180° flipping action. After the flipping is completed, the first lifting cylinder 163 extends again, the first lifting block 161 lifts the material tray body 5, the first push-pull cylinder 143 retracts and resets, and then the first lifting cylinder 163 descends again, so that the material tray body 5 is stably placed upside down on the surface of the first conveying component 13.

[0059] After the tray body 5 is inverted and positioned, the first blocking cylinder 153 descends, the first blocking block 151 releases its limit, the servo motor restarts, and drives the first conveying assembly 13 to transport the tray body 5 to the deep cleaning mechanism 2. The deep cleaning mechanism 2 adopts a symmetrical upper and lower spray pipe layout, and the second spray head 25 can completely cover the entire surface of the tray body 5. The second spray heads 25 are evenly spaced to effectively eliminate cleaning dead corners. After cleaning, the tray body 5 is sent into the drying mechanism 3 by the second conveying assembly 23. The high-speed clean airflow blown by the air knife quickly peels off and removes residual moisture from the surface of the tray, achieving rapid air drying.

[0060] After drying, the tray body 5 is conveyed to the flipping assembly by the third conveying component 33. After the sensor detects the arrival signal of the tray body 5, the second blocking cylinder 453 extends and raises the second blocking block 451 to limit the position. When the tray body 5 is conveyed to the limit position of the second blocking component 45, the servo motor stops working and the fourth conveying component 43 stops operating. Then, the second lifting cylinders 463 on both sides lift the tray body 5 synchronously from the front and rear ends. The second lifting block 461 raises the tray body 5 to the flipping operation height. The second push-pull cylinders 443 on both sides extend respectively, so that the front and rear second rotating fixing sleeves 442 are precisely aligned and docked with the rotating shaft 51 of the tray body 5. After docking, the second lifting cylinders 463 descend and reset, and the second rotating cylinder 441 drives the tray body 5 to complete a 180° flipping action. After the flipping is completed, the second lifting cylinder 463 extends again, the second lifting block 461 lifts the material tray body 5, the second push-pull cylinder 443 retracts and resets, and then the second lifting cylinder 463 descends again, flipping the inverted material tray back to its initial placement state, thus completing the entire automated cleaning and drying process.
