Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically an automatic bread basket cleaning device. Background Technology

[0002] In the bread production process, transfer crates serve as crucial tools for carrying and transporting bread, and their cleanliness directly impacts the hygiene and safety of the bread. Traditional bread crate cleaning typically involves rinsing with a high-pressure water gun, wiping with a clean cloth to remove moisture, and finally drying in an oven or air-drying. This process is currently primarily done manually.

[0003] However, with the expansion of bread production scale and the increase in automation, bread production volume has increased significantly, leading to a greater demand for transfer boxes. Traditional manual cleaning methods, when dealing with a large number of transfer boxes, are not only extremely labor-intensive, requiring a large workforce, but also inefficient, failing to meet the needs of high-efficiency production. Furthermore, manual cleaning can lead to inconsistent cleaning quality, affecting the hygiene and safety of the bread.

[0004] More importantly, the cost of manual cleaning cannot be ignored. On the one hand, labor costs are constantly increasing with changes in the labor market; on the other hand, due to low cleaning efficiency, it may be necessary to increase cleaning equipment and extend cleaning time, further increasing costs. Utility Model Content

[0005] To address the technical problems in the background art, this utility model discloses an automatic bread basket cleaning device.

[0006] This utility model provides an automatic bread basket cleaning device, which includes a cleaning station, a dewatering station and a drying station arranged in sequence, and also includes a conveyor for transporting bread baskets and transferring them between stations.

[0007] The cleaning station is equipped with multiple rectangular water spray pipes arranged side by side at intervals in the direction of bread basket movement. Each side of the water spray pipe is equipped with a fan-shaped nozzle with the spray direction facing the bread basket.

[0008] The dewatering station is equipped with a dewatering fan, whose air outlet faces the bread basket.

[0009] The drying station is equipped with an electric heater and a drying fan. The electric heater heats the air at the air intake of the drying fan, and the air outlet of the drying fan faces the bread basket.

[0010] The bread baskets are arranged horizontally before entering the washing station and when exiting the drying station, and vertically during the process from entering the washing station to exiting the drying station.

[0011] The beneficial effects of the above setup are: 1. The automatic transfer of bread baskets between workstations via conveyor belts greatly reduces manual operation, lowers labor intensity, saves labor costs, and significantly improves cleaning efficiency; 2. The vertical arrangement of bread baskets allows for more bread baskets to be placed at the cleaning, dehydration, and drying workstations, resulting in higher processing efficiency; 3. The setting of water spray pipes and fan-shaped nozzles enables comprehensive and uniform cleaning of the bread baskets; this design ensures consistent cleaning quality, effectively avoids uneven cleaning problems that may occur with manual cleaning, and thus guarantees the hygiene and safety of the bread.

[0012] The conveyor specifically includes: an inlet conveyor connected to the inlet of the cleaning station, a transfer conveyor passing through the cleaning station, the dewatering station and the drying station, and an outlet conveyor connected to the outlet of the drying station; the transfer conveyor is a chain conveyor, on which a bracket is installed that extends outward perpendicular to the conveying direction.

[0013] Because the chain is flexible and prone to sagging, the position of the bread basket is unstable. Based on this, a further improvement is made: the washing station, the dehydration station, and the drying station are all equipped with upper and lower guide rails. The upper chain abuts against the upper end face of the upper guide rail, and the lower chain abuts against the upper end face of the lower guide rail.

[0014] If the chain slides and rubs against the guide rail, it will cause wear on the chain and the guide rail. Based on this, a further improvement is made: the upper guide rail and the lower guide rail are located between the outer chain plate and the inner chain plate of the chain link, and are rolledly connected with the rollers of the chain link.

[0015] The positioning accuracy of the bread basket directly affects the efficiency of washing, dehydration and drying. Based on this, a further improvement is made by setting baffles on both sides of the transfer conveyor in its direction of movement.

[0016] Since bread baskets come in various sizes, the baffle cannot be used for all models. Therefore, a further improvement is made: two parallel, spaced-apart swing arms are connected to the outer side of the baffle; one end of the swing arm is rotatably connected to the baffle, and the other end is fixedly connected to a vertically arranged rotating shaft; the rotating shaft can rotate freely along its axis; by rotating the rotating shaft, the baffles on both sides of the transfer conveyor are driven to move closer or further away, thereby adjusting the spacing of the baffles to match the bread baskets being washed.

[0017] To improve the drying effect of the drying station, avoid heat energy waste, and increase the utilization rate of heat energy, the following design is proposed: the drying station is equipped with a cover, which forms a cavity inside and is connected to the outside only through an air inlet; an electric heater is installed inside the cover; the air intake of the drying fan is connected to the cover and communicates with the inside of the cover.

[0018] Hot air blows towards the bread basket from one side, resulting in low drying efficiency and sometimes leaving parts of the bread basket undried. To address this, a further improvement is made: the drying station is equipped with an air duct connected to the air outlet of the drying fan; the air duct is rectangular, and each side has an air outlet facing inward; the bread basket passes through the rectangular opening formed by the air duct.

[0019] The specific structure of the air passage is as follows: the drying station includes a rectangular outer side plate and an inner side plate, and the outer side plate and the inner side plate form an air passage; air outlets are provided on all four sides of the inner side plate.

[0020] The uniformity of the hot air blown out of the air outlet directly affects the quality and efficiency of drying the bread basket. Based on this, further improvements are made as follows: the upper end of the air duct is connected to the air outlet of the drying fan; a V-shaped diverter plate is set at the center of the air outlet at both the upper and lower ends of the air duct; the diverter plate is perpendicular to the air duct; and the opening end of the diverter plate faces the bread basket.

[0021] The beneficial effects of this utility model are: 1. The automatic transfer of bread baskets between workstations via a conveyor greatly reduces manual operation, lowers labor intensity, saves labor costs, and significantly improves cleaning efficiency; 2. The vertical arrangement of bread baskets allows for the placement of more bread baskets at the cleaning, dehydration, and drying workstations, resulting in higher processing efficiency; 3. The design of water spray pipes and fan-shaped nozzles enables comprehensive and uniform cleaning of the bread baskets. This design ensures consistent cleaning quality and effectively avoids uneven cleaning problems that may occur with manual cleaning, thereby guaranteeing the hygiene and safety of the bread.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0037] like Figure 1-4 , Figure 7 As shown, this utility model discloses an automatic bread basket cleaning device, including a support frame and a housing mounted on the support frame, so that the upper side and four surrounding sides of the utility model are covered by the housing. This utility model includes a cleaning station 1, a dehydration station 2, and a drying station 3 arranged in sequence, and also includes a conveyor for transporting bread baskets 5 for station transfer.

[0038] The conveyor system includes an inlet conveyor 6 connected to the inlet of the cleaning station 1, a transfer conveyor 7 passing through the cleaning station 1, the dewatering station 2, and the drying station 3, and an outlet conveyor 8 connected to the outlet of the drying station 3. The inlet conveyor 6 and the outlet conveyor 8 are both chain plate conveyors, and the transfer conveyor 7 is a chain conveyor with multiple spaced, evenly distributed brackets 71 that are perpendicular to the conveying direction and extend outwards on its chain. The bread basket 5 is arranged horizontally on the inlet conveyor 6 and the outlet conveyor 8, and vertically on the transfer conveyor 7. Specifically: when the bread basket 5 is conveyed to the tail of the inlet conveyor 6, the area between two adjacent brackets 71 is directly opposite the bread basket 5; as the inlet conveyor 6 and the transfer conveyor 7 continue to operate, the outer end of the bread basket 5 is inserted into this area; when the bread basket 5 moves until its center of gravity leaves the inlet conveyor 6, the brackets 71 below the bread basket 5 support it, and the center of gravity of the bread basket 5 is within the range of the brackets 71; as the brackets 71 rotate upward, the bread basket 5 also rotates to an upright position. Moreover, the bread basket is located between the two brackets 71, making its position more stable and preventing it from tipping over.

[0039] When the bread basket 5 is conveyed to the tail of the transfer conveyor 7, the bread basket 5 rotates with the support; when the bread basket 5 rotates to contact the outlet conveyor 8, the bread basket 5 gradually moves towards the outlet conveyor 8 under the action of friction; when the center of gravity of the bread basket 5 is directly above the outlet conveyor 8, the bracket 71 supporting the bread basket 5 is in a downward angle and detaches from the bread basket 5, so that the bread basket 5 moves horizontally on the outlet conveyor 8.

[0040] like Figure 5 and Figure 6 As shown, the support frame is also equipped with horizontally arranged, spaced-apart upper guide rails 13 and lower guide rails 14. The upper chain abuts against the upper end face of the upper guide rail 13, and the lower chain abuts against the upper end face of the lower guide rail 14. The upper guide rails 13 and lower guide rails 14 support the chain, preventing the chain from sagging and affecting the normal transport of the bread basket 5. The upper guide rails 13 and lower guide rails 14 are located between the outer and inner chain plates of the chain links and are connected to the rollers on the chain links in a rolling manner, thus preventing wear on the chain, upper guide rails 13, and lower guide rails 14 when the chain moves.

[0041] The transfer conveyor 7 has baffles 9 on both sides of its direction of movement. Because this invention is relatively long, multiple baffles 9 on each side are configured with their ends abutting or loosely fitted together. The baffles 9 limit the position of the bread basket 5, making its position more stable. Figure 8As shown, two parallel, spaced-apart swing arms 91 are connected to the outer side of the baffle 9. One end of each swing arm 91 is rotatably connected to the baffle 9, and the other end is fixedly connected to a vertically arranged rotating shaft 92. The rotating shaft 92 can rotate freely along its axis. By rotating the rotating shaft 92, the baffles 9 on both sides of the transfer conveyor 7 are driven closer or further away, thereby adjusting the spacing of the baffles 9 to match the bread basket 5 being washed. The specific installation structure of the rotating shaft 92 is as follows: a fixing block 93 is provided on the bracket, and the fixing block 93 is provided with a vertically arranged insertion hole into which the rotating shaft 92 is inserted. The fixing block 93 is also provided with a horizontally arranged threaded hole communicating with the insertion hole. A tightening bolt is threadedly connected to the threaded hole, and its threaded end abuts against the rotating shaft 92 to fix the rotating shaft 92. With this configuration, the shaft can be rotated by loosening the tightening bolt, making operation simple and convenient.

[0042] Driving one of the shafts 92 results in significant resistance, making it difficult to rotate the swing arm 91. Simultaneously driving all four shafts 92 would be labor-intensive. Therefore, one shaft 92 is designated as the driving shaft 97, and the opposite shaft 92 is designated as the driven shaft 98. The lower ends of the driving shaft 97 and the driven shaft 98 are connected by a first link 94, a second link 95, and a third link 96 forming a "Z" shape. The lower end of the driving shaft 97 is fixedly connected to one end of the first link 94; the other end of the first link 94 is hinged to one end of the second link 95; the other end of the second link 95 is hinged to one end of the third link 96; and the other end of the third link 96 is fixedly connected to the lower end of the driven shaft 98. This configuration ensures that when the driving shaft 97 rotates, it drives the driven shaft 98 to rotate as well, causing the other two shafts 92 to rotate as well. Furthermore, it reduces resistance, allowing the driving shaft 97 to easily drive the swing arm 91.

[0043] The cleaning station 1 is equipped with multiple rectangular water spray pipes 11 arranged side by side at intervals in the direction of movement of the bread basket 5. Each side of the water spray pipe 11 is equipped with a fan-shaped nozzle 12 with the spray direction facing the bread basket 5. The fan-shaped nozzle 12 sprays high-pressure water in a fan shape to rinse the bread basket 5.

[0044] The dewatering station 2 is equipped with a dewatering fan 21 located on the top of the housing, with its air outlet facing the bread basket 5, which removes most of the water from the bread basket 5.

[0045] The top of the drying station 3 is equipped with a downward-facing cover 38. The cover 38 and the outer shell form a cavity, which is connected to the outside only through an air inlet 37 on the cover 38. An electric heater 31 is installed inside the cover 38 to heat the air inside. Drying fans 32 are symmetrically arranged on both sides of the cover 38, with their air inlets connected to the cover 38 and communicating with the cavity. The air outlets of the drying fans 32 point downwards, blowing hot air towards the bread basket 5.

[0046] The drying station 3 is also equipped with a rectangular air duct, the center of which connects to the air outlet of the drying fan 32. Each side of the air duct has an inward-facing air outlet 35; the bread basket 5 passes through the rectangular opening formed by the air duct. The specific structure of the air duct is as follows: Figure 9-12 As shown, the system includes a rectangular outer side plate 33 and an inner side plate 34. The outer side plate 33 has a U-shaped cross-section with the opening facing inward. The inner side plate 34 blocks the opening of the outer side plate 33, thus forming an air passage between the outer side plate 33 and the inner side plate 34. Air outlets 35 are provided on all four sides of the inner side plate 34. A V-shaped diverter plate 36 is provided at the center of both the upper and lower air outlets 35 of the air passage. The diverter plate 36 is perpendicular to the air passage, and its open end faces the bread basket 5. The diverter plate 36 ensures that the hot air blown from the drying fan 32 flows evenly to both sides of the upper diverter plate 36, resulting in a uniform heat flow towards the bread basket 5 and improving the drying efficiency of the bread basket 5. A constricted tube 39 is installed at the inner end of the air outlet 35. The flared end of the constricted tube 39 connects to the air outlet 35, and the constricted end of the constricted tube 39 faces the bread basket 5. This is used to increase the airflow velocity and intensity at the outlet of the constriction tube 39, thereby improving the drying effect.

[0047] The beneficial effects of the above setup are: 1. The automatic transfer of bread baskets 5 between workstations via the conveyor greatly reduces manual operation, lowers labor intensity, saves labor costs, and significantly improves cleaning efficiency; 2. The vertical arrangement of bread baskets 5 allows for more bread baskets 5 to be placed at cleaning station 1, dehydration station 2, and drying station 3, resulting in higher processing efficiency; 3. The water spray pipe 11 and fan-shaped nozzle 12 enable comprehensive and uniform cleaning of the bread baskets 5. This design ensures consistent cleaning quality and effectively avoids uneven cleaning problems that may occur with manual cleaning, thereby guaranteeing the hygiene and safety of the bread.

[0048] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
