Description

Technical Field

[0001] This utility model belongs to the technical field of mixing silo devices, specifically relating to the feeding and positioning structure of the mixing silo. Background Technology

[0002] In the feeding operation of mixing silos, existing technologies have long been limited by insufficient feeding positioning accuracy and difficulty in automatic lid opening, which seriously affects feeding efficiency and material quality. Traditional feeding methods mostly rely on manual visual positioning of conveyor belts or simple mechanical stops for limiting. This not only makes it difficult to accurately align the silo with the hopper inlet, but also often leads to material spillage due to positioning deviations, resulting in raw material waste and increased subsequent cleaning workload. Furthermore, it is impossible to flexibly adjust the positioning position according to the silo specifications. The silo lid opening action still generally requires manual handling and lifting, resulting in large feeding deviations and dust escape. Repeated disassembly and reassembly of the lid can easily deform it, and there is a lack of detection methods, often resulting in the lid not returning to its original position or getting stuck. At the same time, manual contact with materials can easily introduce microorganisms or impurities for contamination, making it particularly unsuitable for fields with high cleanliness requirements.

[0005] It also includes a cover opening device, which is connected to the side of the feeding device near the hopper.

[0006] The feature of this utility model is that,

[0007] The feeding device includes a feeding frame with four legs fixed to the bottom of the feeding frame. The hopper is bolted to the bottom of the feeding frame near the opening device. A first servo motor is fixedly connected to the side of the feeding frame away from the hopper. A first lead screw is connected to the output end of the first servo motor. A first slide rod is provided on the side of the feeding frame away from the first lead screw. Clamping blocks are slidably connected to the first lead screw and the first slide rod.

[0008] There are two clamping blocks, and the distance between the two clamping blocks is the same as the length of the placement tray. The placement tray is slidably connected to the feeding rack and is located between the two clamping blocks.

[0009] The feeding rack has feeding grooves on both sides. The first lead screw and the first slide rod are located in the feeding grooves. The two ends of the clamping block are located in the feeding grooves on both sides. The first lead screw and the first slide rod pass through the two ends of the clamping block respectively. The first lead screw is threadedly engaged with the clamping block, and the first slide rod is slidably engaged with the clamping block.

[0010] The opening device includes an extension plate, which is fixedly connected to a feeding frame. A cylinder is fixedly mounted on the extension plate, and a push rod is connected to the cylinder. The push rod passes through the extension plate, and a mounting frame is fixedly mounted to one end of the push rod. A second servo motor is fixedly mounted to one side of the mounting frame, and a second lead screw is connected to the output end of the second servo motor. The second lead screw passes through the mounting frame and is connected to a moving plate.

One end of the bracket is fixedly connected to the extension plate, and the other end is fixedly connected to the feeding rack.

[0014] The bottom of the material box has a groove that matches the lid.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The mixing hopper feeding and positioning structure provided by this utility model, through the coordinated drive and guiding structure of the first servo motor, the first lead screw and the first slide bar, and the feeding chutes on both sides of the feeding frame, forms a stable linear movement path. The first servo motor can be precisely controlled by an external main controller to drive the clamping blocks to move smoothly along the first lead screw. The distance between the two clamping blocks is completely matched with the length of the placement tray, which can form a bidirectional limit on the placement tray and prevent the placement tray from deviating during the feeding process. At the same time, the feeding chutes form a wrapping guide for both ends of the clamping blocks to prevent the clamping blocks from rotating, ensuring that the straightness error of the placement tray and the material box is small when they move, and can accurately deliver the material box to the top of the hopper.

[0017] (2) The mixing hopper feeding and positioning structure provided by this utility model can automatically complete the entire process from hook avoidance → alignment → opening the cover → unloading → closing the cover by combining the combined action of cylinder height adjustment and horizontal drive of the second servo motor with the precise position detection of the detection block and proximity switch. At the same time, there is no manual contact with the material throughout the process, which effectively avoids microbial or impurity contamination, and is especially suitable for fields with high cleanliness requirements such as food and medicine.

[0018] (3) The mixing hopper feeding and positioning structure provided by this utility model has a rigid fixing between the material box and the placement tray through the pin hole and the limiting pin, which can effectively prevent the material box and the placement tray from sliding relative to each other during the feeding process. The hanging ears fixed on the placement tray not only facilitate the gripping of the external lifting feeding device or clamping device, but also further improve the positioning stability of the placement tray on the feeding rack. In addition, the bottom of the material box has a groove that matches the lid, which not only facilitates the sliding opening and closing of the lid, but also forms a pre-limiting position for the lid during the feeding process, avoiding the lid from shifting and causing premature material leakage. In actual testing, the material box still did not shake or tip over, and the structural stability is significantly better than that of the traditional design.

[0019] (4) The mixing bin feeding and positioning structure provided by this utility model has hooks made of high rigidity and low elastic deformation metal material, which can avoid the alignment deviation caused by force deformation when the box cover moves; at the same time, the hooks are set on both sides of the box cover, away from the unloading area of ​​the box, which can effectively avoid the impact of falling materials and reduce the wear of hooks.

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] This utility model provides a feeding and positioning structure for a mixing hopper, such as... Figure 1 and Figure 4 As shown, the system includes a material box 1, a feeding device 2, and a hopper 5. A placement tray 6 is attached to the bottom of the material box 1, and a lid 9 is slidably connected to the material box 1. Both the material box 1 and the placement tray 6 have pin holes 8, into which limit pins 4 are inserted. A hanging lug 7 is fixedly connected to the placement tray 6. The feeding device 2 is located at the top of the hopper 5. The system also includes a lid opening device 3, which is connected to the feeding device 2 on the side closest to the hopper 5. Figure 2 and Figure 5 As shown, the feeding device 2 includes a feeding frame 200. Support legs 203 are fixedly connected to the four sides of the bottom of the feeding frame 200. The hopper 5 is bolted to the bottom of the feeding frame 200 near the opening device 3. A first servo motor 204 is fixedly connected to the side of the feeding frame 200 away from the hopper 5. A first lead screw 205 is connected to the output end of the first servo motor 204. A first slide bar 202 is provided on the side of the feeding frame 200 away from the first lead screw 205. Clamping blocks 206 are slidably connected to the first lead screw 205 and the first slide bar 202. There are two clamping blocks 206. The distance between the two clamping blocks 206 is the same as the length of the placement tray 6. The placement tray 6 is slidably connected to the feeding frame 200 and is located between the two clamping blocks 206. The feeding rack 200 has feeding grooves 201 on both sides. The first lead screw 205 and the first sliding rod 202 are located within the feeding grooves 201. The clamping block 206 has its two ends located within the feeding grooves 201 on both sides. The first lead screw 205 and the first sliding rod 202 pass through both ends of the clamping block 206. The first lead screw 205 is threadedly engaged with the clamping block 206, and the first sliding rod 202 is slidably engaged with the clamping block 206. Figure 3 and Figure 6As shown, the opening device 3 includes an extension plate 300, which is fixedly connected to the feeding frame 200. A cylinder 302 is fixedly connected to the extension plate 300, and a push rod 303 is connected to the cylinder 302. The push rod 303 passes through the extension plate 300, and a mounting frame 304 is fixedly connected to one end of the push rod 303. A second servo motor 306 is fixedly connected to one side of the mounting frame 304, and a second lead screw 307 is connected to the output end of the second servo motor 306. The second lead screw 307 passes through the mounting frame 304 and is connected to a moving plate 308. A second sliding rod 305 is also connected to the side of the mounting frame 304, and the second sliding rod 305 is slidably connected to the moving plate 308. A hook 310 is fixedly connected to the side of the moving plate 308 away from the mounting frame 304, and a limit protrusion 311 is fixedly connected to the hook 310. The second lead screw 307 and the second slide bar 305 are both rotatably connected to the mounting bracket 304, and the moving plate 308 is threadedly connected to the second lead screw 307; a detection block 309 is fixedly connected to one side of the moving plate 308. Figure 5 As shown, a proximity switch 312 is fixedly connected to the side of the feeding rack 200 near the hopper 5. A bracket 301 is fixedly connected to the bottom of the extension plate 300. One end of the bracket 301 is fixedly connected to the extension plate 300, and the other end is fixedly connected to the feeding rack 200. The bottom of the material box 1 has a groove that matches the box cover 9. The length and width of the groove are in a transitional fit with the length and width of the box cover 9.

[0029] The working principle is as follows: The motor and proximity switch 312 of this device need to be connected to an external main controller, and the outlet of the hopper 5 needs to be connected to subsequent mixing and stirring equipment. In use, different bulk materials are loaded into the material box 1 and the lid 9 is slid on. The material box 1 is inverted and placed on the placement tray 6. The placement tray 6 and the material box 1 are placed on the feeding rack 200 by the lifting and feeding device, and the placement tray 6 is positioned between the two clamping blocks 206.

[0030] When the first servo motor 204 is working, it drives the clamping block 206 to move through the first lead screw 205. When the clamping block 206 moves, it will cause the placement tray 6 and the material box 1 to slide on the feeding rack 200. By controlling the output rotation direction of the first servo motor 204, the clamping block 206 can drive the placement tray 6 to the extreme position of the first lead screw 205 away from the first servo motor 204. In the design, this position is just so that the placement tray 6 and the material box 1 are directly above the hopper 5. Alternatively, a proximity switch can be added to the feeding rack 200 to detect the movement position of the clamping block 206 to achieve positioning.

[0031] When the material box 1 is directly above the hopper 5, the lid opening device 3 operates. First, the cylinder 302 takes in air and pushes the push rod 303 downward. When the push rod 303 pushes down, it causes the mounting bracket 304 to move downward. At this time, the hook 310 on the moving plate 308 is misaligned with the material box 1 and the lid 9, meaning that the hook 310 will not interfere with the material box 1 and the lid 9 when it moves. The second servo motor 306 drives the second lead screw 307 to rotate. The second lead screw 307 engages with the moving plate 308, causing the moving plate 308 and the hook 310 to move towards the side of the material box 1. When the detection block 309 on the moving plate 308 is detected by the proximity switch 312, the head of the hook 310 just passes the lid 9. Air is drawn in, causing the cylinder 302 to retract the push rod 303. The retraction of the push rod 303 causes the mounting bracket 304 to rise. At this time, the hook 310 is located below the lid 9 and flush with the lid 9. The head of the hook 310... Located on the side of the lid 9 away from the moving plate 308, the second servo motor 306 is reversed, and the moving plate 308 will move towards the side of the second servo motor 306. When the moving plate 308 moves, the hook 310 drives the lid 9 to move, thereby using the hook 310 to push the lid 9 out of the material box 1. At this time, the material in the material box 1 will fall into the hopper 5. The position of the hook 310 should be as close as possible to both sides of the lid 9 to avoid damage to the hook 310 when the material falls. After the material box 1 is unloaded, the second servo motor 306 reverses again, causing 208 to move towards the side of the material box 1. Similarly, when the detection block 309 is detected by the proximity switch 312, the lid 9 is inserted back into the material box 1. In order to ensure that the lid 9 can be smoothly inserted back into the material box 1, the lid 9 and the material box 1 are fitted with a clearance, and the hook 310 needs to be made of a metal material with high rigidity and small elastic deformation to maintain the accuracy of the lid 9 when it moves. After the lid 9 is reinserted into the material box 1, the cylinder 302 pushes the push rod 303 out again, causing the hook 310 to be misaligned with the lid 9. This allows the second servo motor 306 to drive the moving plate 308 and the hook 310 to reset to the side of the second servo motor 306 via the second lead screw 307, and then retract the push rod 303, thus completing the entire unloading process.

[0032] The first servo motor 204 is reversed to drive the clamping block 206 and the placement tray 6 back to the loading and unloading position. Using the loading and unloading tools, the placement tray 6 and the material box 1 after unloading are removed, and a new placement tray 6 and the material box 1 are placed. The above process is repeated to realize the function of adding mixed raw materials again.

[0033] The entire process can be coordinated with a conveying device and a lifting and rotating clamping device to achieve automated material loading. For example, the clamping device is set on the side of the feeding rack 200 near the first servo motor 204, and two conveyor belts are set on both sides of the clamping device. The operator only needs to add raw materials to the material box 1, cover it with the lid 9, invert it on the placement tray 6, insert the limit pin 4, and then place it on the conveyor belt. The conveying device transports it to one side of the clamping device. The clamping device first clamps the placement tray 6 that has been unloaded from the feeding device 2 and places it on the other side of the conveyor belt. Then the clamping device clamps the placement tray 6 that has just been conveyed and places it on the feeding device 2. This process is repeated to add a variety of mixed raw materials.

[0045] Example 6

[0046] Based on embodiment 5, a detection block 309 is fixedly connected to one side of the moving plate 308, a proximity switch 312 is fixedly connected to the side of the feeding rack 200 near the hopper 5, a bracket 301 is fixedly connected below the extension plate 300, one end of the bracket 301 is fixedly connected to the extension plate 300, and the other end is fixedly connected to the feeding rack 200; a groove matching the box cover 9 is opened at the bottom of the material box 1, and the length and width of the groove are in transitional fit with the length and width of the box cover 9.

[0047] When the material box 1 is directly above the hopper 5, the lid opening device 3 operates. First, the cylinder 302 takes in air and pushes the push rod 303 downward. When the push rod 303 pushes down, it causes the mounting bracket 304 to move downward. At this time, the hook 310 on the moving plate 308 is misaligned with the material box 1 and the lid 9, meaning that the hook 310 will not interfere with the material box 1 and the lid 9 when it moves. The second servo motor 306 drives the second lead screw 307 to rotate. The second lead screw 307 engages with the moving plate 308, causing the moving plate 308 and the hook 310 to move towards the side of the material box 1. When the detection block 309 on the moving plate 308 is detected by the proximity switch 312, the head of the hook 310 just passes the lid 9. Air is drawn in, causing the cylinder 302 to retract the push rod 303. The retraction of the push rod 303 causes the mounting bracket 304 to rise. At this time, the hook 310 is located below the lid 9 and flush with the lid 9. The head of the hook 310... Located on the side of the lid 9 away from the moving plate 308, the second servo motor 306 is reversed, and the moving plate 308 will move towards the side of the second servo motor 306. When the moving plate 308 moves, the hook 310 drives the lid 9 to move, thereby using the hook 310 to push the lid 9 out of the material box 1. At this time, the material in the material box 1 will fall into the hopper 5. The position of the hook 310 should be as close as possible to both sides of the lid 9 to avoid damage to the hook 310 when the material falls. After the material box 1 is unloaded, the second servo motor 306 reverses again, causing 208 to move towards the side of the material box 1. Similarly, when the detection block 309 is detected by the proximity switch 312, the lid 9 is inserted back into the material box 1. In order to ensure that the lid 9 can be smoothly inserted back into the material box 1, the lid 9 and the material box 1 are fitted with a clearance, and the hook 310 needs to be made of a metal material with high rigidity and small elastic deformation to maintain the accuracy of the lid 9 when it moves. After the lid 9 is reinserted into the material box 1, the cylinder 302 pushes the push rod 303 out again, causing the hook 310 to be misaligned with the lid 9. This allows the second servo motor 306 to drive the moving plate 308 and the hook 310 to reset to the side of the second servo motor 306 via the second lead screw 307, and then retract the push rod 303, thus completing the entire unloading process.

[0048] The first servo motor 204 is reversed to drive the clamping block 206 and the placement tray 6 back to the loading and unloading position. Using the loading and unloading tools, the placement tray 6 and the material box 1 after unloading are removed, and a new placement tray 6 and the material box 1 are placed. The above process is repeated to realize the function of adding mixed raw materials again.

[0049] The entire process can be coordinated with a conveying device and a lifting and rotating clamping device to achieve automated material loading. For example, the clamping device is set on the side of the feeding rack 200 near the first servo motor 204, and two conveyor belts are set on both sides of the clamping device. The operator only needs to add raw materials to the material box 1, cover it with the lid 9, invert it on the placement tray 6, insert the limit pin 4, and place it on the conveyor belt. The conveying device transports it to one side of the clamping device. The clamping device first clamps the placement tray 6 that has been unloaded from the feeding device 2 and places it on the other side of the conveyor belt. Then the clamping device clamps the placement tray 6 that has just been conveyed and places it on the feeding device 2. This process is repeated to achieve automatic addition of various mixed raw materials.
