Description

Technical Field

[0001] This application relates to the field of flour processing, and in particular to automated feeding production lines for flour mills. Background Technology

[0002] Flour is a powdery substance made from milled wheat and is one of the most common food ingredients. The main components of flour include starch, protein, and fat. Based on protein content, it can be classified into high-gluten flour, medium-gluten flour, low-gluten flour, and gluten-free flour. Flour is a staple food in most parts of northern China and can be made into steamed buns, dumplings, bread, and other foods. Foods made from flour are numerous, varied, and have diverse flavors. Feeding devices are needed to add flour during processing and packaging.

[0003] Feeding typically involves conveying large quantities of wheat stacked on shovels via a conveyor belt. During processing, a forklift is used to move the shovels onto the conveyor belt, which then transports the wheat to the feeding machine, where it is fed into the processing equipment. Since the raw material conveying line and the processing machine are usually adjacent, the processed flour is prone to dust contamination. Therefore, explosion-proof measures are required for the raw material conveying line to prevent the flour processing from affecting the raw materials. Utility Model Content

[0004] To address the issue that raw material conveying and processing machines are often adjacent, leading to dust problems in the processed flour, this application provides an automated feeding production line for flour mills.

[0005] The automatic feeding production line for flour mills provided in this application adopts the following technical solution: it includes a partitioned silo, an AGV vehicle body, and a rail conveyor. A feeding machine body is fixed inside one side of the partitioned silo. A door is opened through one side of the partitioned silo. The rail conveyor passes through the inside of the door, and guide rails are fixed on both sides of the door. A telescopic cylinder is fixed on the top of the partitioned silo. A silo door is fixed at the power output end of the telescopic cylinder. The two sides of the silo door are slidably connected to the two guide rails respectively, and limit blocks are fixed at the bottom of the two guide rails.

[0006] By adopting the above technical solution, the silo door is made of metal to avoid static electricity generated when the silo door moves, thereby reducing the risk of flour dust explosion. The lifting and lowering of the silo door is controlled by a telescopic cylinder. When conveying raw materials for flour production, the silo door is opened. After the raw materials are conveyed, the telescopic cylinder is controlled to extend until the silo door touches the limit block. At this time, the silo door is located at the top of the track conveyor.

[0007] Preferably, the top of the track conveyor is provided with a first roller, and multiple first rollers are provided. The multiple first rollers are arranged at equal intervals along the top of the inner wall of the track conveyor, and the multiple first rollers are connected to each other in pairs.

[0008] By adopting the above technical solution, multiple first rollers are connected to each other in pairs, and the shovels containing raw materials are transported from the outside box compartment to the inside by a rail conveyor.

[0009] Preferably, the track conveyor is U-shaped, and a rotating handle is rotatably connected to one side of the track conveyor near the partition compartment and at the outer end of the partition compartment. One end of the rotating handle is fixed to one end of one of the first rollers.

[0010] By adopting the above technical solution and using the rotating handle, when an electrical fault occurs in the entire production line and automatic feeding cannot be performed, manual mechanical control can be switched to. By manually turning the knob handle, multiple first rollers can be rotated to complete temporary manual conveying.

[0011] Preferably, an explosion-proof motor is fixed at the middle of one end of the track conveyor, an explosion-proof electrical box is fixed on one side of the track conveyor, and a support frame is fixed at the bottom of the track conveyor. Multiple support frames are provided and are arranged at equal intervals at the bottom of the track conveyor.

[0012] By adopting the above technical solution, the first roller located at the edge is driven to rotate by an explosion-proof motor, which in turn drives multiple first rollers to rotate, thereby conveying the raw materials to the shovel plate. The use of explosion-proof motors and electrical boxes further improves the safety of use.

[0013] Preferably, each of the multiple support frames has a support leg threaded to both ends of its bottom, and the height of the support leg is 25-35mm.

[0014] By adopting the above technical solution, the track conveyor is supported by a support frame, and the position of the support frame can be adjusted according to the ground height difference to keep the track conveyor level and make the conveying more stable.

[0015] Preferably, the AGV body has multiple second rollers horizontally and equidistantly arranged on the top, and a touch control screen is fixed on one side of the AGV body, with an explosion-proof protective cover hinged to the outer wall of the touch control screen.

[0016] By adopting the above technical solution, the AGV vehicle body can be set and controlled through the set touch control screen, and it also has a maintenance prompt function. The touch control screen is protected by an explosion-proof cover to prevent damage to the touch control screen.

[0017] Preferably, the horizontal height of the AGV body is the same as the horizontal height of the rail conveyor, and the AGV body is located inside the partitioned compartment on the side close to the feeding machine and the rail conveyor.

[0018] By adopting the above technical solution, with the AGV body located at the feeding machine and the rail conveyor, after the feeding machine has finished feeding the raw materials from the shovel above the rail conveyor, the rail conveyor continues to work, moving the empty shovel to the top of the AGV body. The AGV body then places the empty shovel in the empty space in the middle of the U-shaped rail conveyor for subsequent forklifts to place raw materials.

[0019] In summary, this application includes at least the following beneficial technical effects:

[0020] 1. In this application, when feeding flour, the explosion-proof electrical box controls the rotation of the explosion-proof motor, which drives the first roller located at the edge to rotate, and drives multiple first rollers to rotate, thus conveying the raw materials on the shovel plate. At the same time, the telescopic cylinder controls the raising and lowering of the silo door. When conveying raw materials for flour production, the telescopic cylinder shortens to open the silo door. When the raw materials are conveyed into the compartment, the telescopic cylinder is extended until the silo door touches the limit block. At this time, the silo door is located at the top of the track conveyor, thereby effectively preventing the raw materials from being affected by dust explosions.

[0021] 2. In this application, the AGV vehicle body is located at the feeding machine and the rail conveyor. After the feeding machine finishes feeding the raw material from the shovel plate above the rail conveyor, the rail conveyor continues to work, moving the empty shovel plate to the top of the AGV vehicle body. The AGV vehicle body then places the empty shovel plate in the empty space in the middle of the U-shaped rail conveyor for subsequent forklifts to place raw materials, thereby achieving higher production line conveying efficiency and more convenient shovel plate recovery.

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0028] This application discloses an automated feeding production line for a flour mill, including a partitioned silo 1, an AGV vehicle 3, and a track conveyor 9. A feeding machine 2 is fixed to one side of the partitioned silo 1, through which the flour raw materials conveyed by the track conveyor 9 are fed into the processing equipment. A doorway 4 is opened through one side of the partitioned silo 1, through which the track conveyor 9 passes. Guide rails 5 are fixed on both sides of the doorway 4. A telescopic cylinder 7 is fixed to the top of the partitioned silo 1, and a silo door 8 is fixed to the power output end of the telescopic cylinder 7. The two sides of the silo door 8 are slidably connected to two guide rails 5, and limit blocks 6 are fixed to the bottom of the two guide rails 5. The silo door 8 is made of metal to avoid static electricity generated when the silo door 8 moves, thereby reducing the risk of flour dust explosion. The telescopic cylinder 7 controls the raising and lowering of the silo door 8. When conveying flour production raw materials, the silo door 8 is opened. After the raw materials are conveyed, the telescopic cylinder 7 is extended until the silo door 8 touches the limit block 6. At this time, the silo door 8 is located on top of the track conveyor 9.

[0029] Reference Appendix Figure 3 The track conveyor 9 is equipped with a first roller 11 on its top. Multiple first rollers 11 are arranged at equal intervals along the top of the inner wall of the track conveyor 9. The multiple first rollers 11 are connected to each other in pairs. The track conveyor 9 transports the shovel plate containing the raw materials from the inside of the outer box separation silo 1.

[0030] Reference Appendix Figure 1 The track conveyor 9 is U-shaped. A rotating handle 10 is rotatably connected to one side of the track conveyor 9 that is close to the partition compartment 1 and located at the outer end of the partition compartment 1. One end of the rotating handle 10 is fixed to one end of one of the first rollers 11. The rotating handle 10 allows for manual mechanical control when an electrical fault occurs in the entire production line and automatic feeding cannot be performed. By manually rotating the knob handle 11, multiple first rollers 11 are rotated to complete temporary manual conveying.

[0031] Reference Appendix Figure 3 An explosion-proof motor 12 is fixed at the middle of one end of the track conveyor 9, an explosion-proof electrical box 13 is fixed on one side of the track conveyor 9, and a support frame 14 is fixed at the bottom of the track conveyor 9. Multiple support frames 14 are arranged at equal intervals at the bottom of the track conveyor 9. The explosion-proof motor 12 drives the first roller 11 located at the edge to rotate, thereby driving multiple first rollers 11 to rotate and conveying the raw materials of the shovel plate. The use of explosion-proof motors and electrical boxes 13 further improves the safety of use.

[0032] Reference Appendix Figure 3 Each of the multiple support frames 14 has a support leg 15 threaded to both ends of its bottom. The height of the support leg 15 is 25-35mm. The support frame 14 supports the track conveyor 9. At the same time, the position of the support frame 15 can be adjusted according to the ground height difference to keep the track conveyor 9 horizontal and make the conveying more stable.

[0033] Reference Appendix Figure 4 The AGV body 3 has multiple second rollers 16 arranged horizontally and equidistantly on its top. A touch control screen 17 is fixed on one side of the AGV body 3. An explosion-proof protective cover 18 is hinged to the outer wall of the touch control screen 17. The AGV body 3 can be set and controlled through the touch control screen 17, and it also has a maintenance prompt function. The explosion-proof protective cover 18 protects the touch control screen 17 to prevent damage.

[0034] Reference Appendix Figure 1 and 2 The AGV body 3 is at the same horizontal height as the rail conveyor 9. The AGV body 3 is located inside the partition compartment 1, close to the feeding machine body 2 and the rail conveyor 9. The AGV body 3 is located at the feeding machine body 2 and the rail conveyor 9. After the feeding machine 2 finishes feeding the raw material from the shovel plate above the rail conveyor 9, the rail conveyor 9 continues to work, moving the empty shovel plate to the top of the AGV body 3. The AGV body 3 places the empty shovel plate in the empty space in the middle of the U-shaped rail conveyor 9 for subsequent forklifts to place raw materials.

[0035] The implementation principle of the automatic feeding production line for flour mills in this embodiment is as follows: First, a forklift places multiple shovels, which were placed in the empty space in the middle of the U-shaped track conveyor 9, above the track conveyor 9. Then, flour is fed in. The explosion-proof electrical box 13 controls the explosion-proof motor 12 to rotate. The explosion-proof motor 12 drives the first roller 11 located at the edge to rotate, which in turn drives multiple first rollers 11 to rotate, conveying the raw materials to the shovels. At the same time, the telescopic cylinder 7 controls the raising and lowering of the hopper door 8. When conveying raw materials for flour production, the telescopic cylinder 7 shortens to open the hopper door 8. When the raw materials are conveyed into the partition compartment 1, the telescopic cylinder 7 is controlled to extend. The hopper door 8 extends until it touches the limit block 6. At this time, the hopper door 8 is located on top of the rail conveyor 9. At the same time, the explosion-proof motor 12 stops. The flour raw material conveyed by the rail conveyor 9 is put into the processing equipment through the feeding machine body 2. Then, the above steps are repeated to convey new raw materials again. The AGV body 3 is located at the feeding machine body 2 and the rail conveyor 9. After the feeding machine 2 finishes feeding the raw material on the shovel plate above the rail conveyor 9, the rail conveyor 9 continues to work and moves the empty shovel plate to the top of the AGV body 3. The AGV body 3 places the empty shovel plate in the empty space in the middle of the U-shaped rail conveyor 9 for the subsequent forklift to place raw materials.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
