Description

Technical Field

[0001] This utility model relates to the field of lily processing technology, and in particular to a lily grinding device. Background Technology

[0002] A lily grinding device, a processing equipment for grinding dried lily bulbs into powder, is widely used in the food, pharmaceutical, and health product industries. It mainly realizes key processes such as crushing, fine grinding, sieving, and collecting raw materials, effectively improving the processing efficiency of lily powder, ensuring the uniformity of product fineness, and preserving its nutritional components. Publication number CN213050820U discloses a lily grinding device, relating to the field of lily processing technology, including a housing, a grinding tank, grinding components, and an extrusion belt. The top of the housing is equipped with a feed hopper communicating with the interior. The opening of the feed hopper facing the inside of the box is flush with the gap between the two sets of extrusion belts. The two sets of extrusion belts are positioned opposite each other at the top of the box. Below the extrusion belts, there is a grid plate. Two sets of grid plates are distributed at an angle. The two sets of grid plates are fixedly installed above the water collection tank at the top opening. Below the water collection tank, there is a grinding pool. Inside the grinding pool, there is a grinding assembly that moves in an arc along the inner wall of the grinding pool. The grinding pool is located at the bottom of the box, and the grinding assembly includes at least a pressure roller and swing rods vertically and symmetrically distributed on both sides of the pressure roller. This lily grinding device has a reasonable structure, high grinding efficiency, and good grinding quality, and can be widely promoted. This utility model can achieve efficient grinding of lilies by setting up a box, grinding pool, grinding components and extrusion belt. However, in the face of different industries' different needs for the particle size of lily powder, it cannot adjust the particle size of the lily powder after grinding. As a result, when the food industry needs coarse lily powder to make lily cakes and lily porridge, the fine powder is easy to clump, affecting the taste and failing to meet the precision requirements, which affects the production efficiency. Therefore, it needs to be improved. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a lily grinding device, including a grinding box, a crushing box fixedly installed on the surface of the grinding box, a feeding box fixedly installed on the surface of the crushing box, a feeding motor fixedly installed on the surface of the feeding box, a feeding shaft fixedly installed at the output end of the feeding motor, a baffle fixedly installed on the surface of the feeding shaft, a grinding motor fixedly installed on the surface of the grinding box, a grinding shaft fixedly installed inside the grinding box, a motor frame fixedly installed at the output end of the grinding motor, a lead screw motor and a sleeve fixedly installed on the surface of the motor frame, a lead screw fixedly installed at the output end of the lead screw motor, a lead screw block threadedly connected to the surface of the lead screw, a grinding roller rotatably connected to the surface of the lead screw block, a sliding block rotatably connected to the other end of the grinding roller, a fixing block rotatably connected to the surface of the grinding shaft, and a sliding rod fixedly installed on the surface of the fixing block.

[0005] Preferably, the surface shape of the baffle is the same as the surface shape of the inner side of the feeding box, and the surface of the feeding shaft is rotatably connected to the interior of the feeding box. Here, the rotatable connection of the feeding shaft allows the baffle to rotate flexibly with the feeding shaft. By adjusting the speed of the feeding motor, the feeding speed can be precisely controlled, avoiding a large influx of raw materials into the crushing box at once and causing blockage. This ensures the orderly progress of subsequent crushing and grinding processes, reduces frictional wear between the raw materials and the inner wall of the feeding box, extends the service life of the equipment, and improves the overall grinding efficiency and raw material utilization rate.

[0006] Preferably, the lead screw and the slide bar are of the same length and symmetrically distributed on both sides of the grinding roller, with a sliding connection between the surface of the slide bar and the interior of the slide bar block. Here, when the lead screw motor drives the lead screw to rotate, the lead screw block moves along the lead screw axis, while the slide bar block slides synchronously along the slide bar. Because the two are of the same length and symmetrically distributed, it ensures that the grinding roller always maintains a horizontal state for height adjustment, avoiding tilting of the grinding roller due to uneven force, thereby ensuring consistent grinding precision of lily raw materials at different positions. When fine powder is required, the distance between the grinding roller and the bottom surface of the grinding box can be reduced to allow the raw material to be fully ground; when coarse powder is required, the distance can be increased to meet the needs of different usage scenarios. Furthermore, the sliding cooperation between the slide bar and the slide bar block reduces jamming during the adjustment process and improves the smoothness of equipment operation.

[0007] Preferably, the bottom surface of the grinding box is arc-shaped, and the inner side of the sleeve block and the surface of the lead screw block are in close contact. Here, the rotational power of the grinding motor can be stably transmitted to the lead screw block during equipment operation, thereby driving the grinding roller to rotate synchronously around the grinding shaft. This ensures that the grinding roller can roll evenly along the arc-shaped bottom surface, performing all-round grinding of the lily raw material inside the box, avoiding grinding dead angles. The sleeve block can isolate the lead screw from the powder generated during the grinding process, preventing powder from adhering to the lead screw surface and affecting the thread transmission accuracy, effectively protecting the lead screw structure, reducing equipment failures, extending the lead screw's service life, ensuring the stable implementation of the grinding roller height adjustment function, and improving overall grinding efficiency and powder uniformity in conjunction with the arc-shaped bottom surface.

[0008] Preferably, a crushing motor is fixedly installed on the surface of the crushing box, a main crushing roller is fixedly installed at the output end of the crushing motor, a main rotating shaft is fixedly installed at the other end of the main crushing roller, a rotating belt is tumbledly connected to the surface of the main rotating shaft, a driven rotating shaft is tumbledly connected to the inner side of the rotating belt, a driven crushing roller is fixedly installed on the surface of the driven rotating shaft, and a crushing shaft is fixedly installed on the surface of the driven crushing roller. Here, the main crushing roller is directly driven to rotate by the crushing motor. At the same time, the main shaft drives the driven shaft to rotate synchronously through the shaft belt. This makes the driven crushing roller and the main crushing roller rotate in opposite directions and at the same speed. This reduces equipment energy consumption and manufacturing costs, and ensures the coordination of the operation of the two crushing rollers. It ensures that the lily raw material fed into the crushing box can be evenly clamped and crushed, avoiding the problem of raw material accumulation or incomplete crushing caused by the rotation of a single roller. The rotational connection between the crushing shaft and the crushing box provides stable support for the driven crushing roller, reducing its shaking during rotation, and further improving the stability and crushing efficiency of the crushing process. The lily raw material is crushed to a suitable particle size for grinding, effectively reducing the load on subsequent grinding processes.

[0009] Preferably, the main crushing roller and the driven crushing roller are symmetrically distributed on both sides of the crushing chamber, and the surface of the crushing shaft is rotatably connected to the interior of the crushing chamber. This arrangement allows the two crushing rollers to form a uniform clamping space. When the lily raw material enters the crushing chamber, it can be simultaneously squeezed and sheared by the two rollers, preventing uneven crushing due to force deviation. Whether the lily raw material is in block or flake form, a consistent crushing effect can be achieved, effectively reducing the residue of large pieces of raw material. The crushing shaft not only provides stable rotational support for the driven crushing roller but also reduces the frictional resistance during rotation, minimizing component wear and ensuring that the driven crushing roller maintains a stable rotational state over a long period. This, combined with the main crushing roller, efficiently completes the crushing operation, supplying uniformly sized raw materials for subsequent grinding processes, further improving the overall processing quality and operational stability of the grinding device.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting up a feeding shaft, baffle, grinding motor, lead screw, slide bar, and grinding roller, the feeding motor drives the feeding shaft to rotate, which in turn drives the baffle that is attached to the inside of the feeding box to rotate synchronously. The feeding rate can be controlled as needed to avoid raw material accumulation. The grinding motor drives the grinding mechanism to operate, and the lead screw motor drives the lead screw to rotate, which causes the lead screw block to move the grinding roller. At the same time, the slide bar provides stable guidance for the grinding roller to ensure its horizontal adjustment height. By adjusting the distance between the grinding roller and the bottom surface of the grinding box, the powder coarseness can be precisely controlled. As the grinding roller rotates with the grinding motor, it can grind the raw material, improve grinding efficiency and powder uniformity, and meet the grinding needs in different scenarios.

[0012] 2. In this utility model, by setting up a crushing motor, a main crushing roller, a driven crushing roller, a rotating belt, and a crushing shaft, the crushing motor drives the main crushing roller to rotate. The main rotating shaft at the other end of the main crushing roller drives the driven rotating shaft to rotate synchronously through the rotating belt. This makes the driven crushing roller and the main crushing roller operate in opposite directions and at the same speed, ensuring the coordination of the two rollers. When the lily raw material enters the crushing box from the feeding box, the symmetrically distributed main and driven crushing rollers can uniformly clamp, squeeze, and shear the raw material, avoiding material deviation or accumulation, and ensuring consistent crushing particle size. The crushing shaft provides stable support for the driven crushing roller, reducing its shaking during operation, improving the stability and efficiency of the crushing process, crushing the raw material to a suitable grinding particle size, effectively reducing the load on subsequent grinding processes, and ensuring the smoothness and processing quality of the overall grinding process.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1

[0023] Please see Figure 1-4This utility model provides a technical solution: a lily grinding device, including a grinding box 1, a crushing box 2 fixedly installed on the surface of the grinding box 1, realizing the pre-treatment crushing of lily raw materials, crushing the raw materials to a suitable particle size for grinding, effectively reducing the load of the subsequent grinding process in the grinding box 1. A feeding box 3 is fixedly installed on the surface of the crushing box 2, a feeding motor 4 is fixedly installed on the surface of the feeding box 3, a feeding shaft 5 is fixedly installed at the output end of the feeding motor 4, a baffle 6 is fixedly installed on the surface of the feeding shaft 5, the surface shape of the baffle 6 is the same as the surface shape of the inner side of the feeding box 3, and the surface of the feeding shaft 5 and the interior of the feeding box 3 are rotatably connected. Here, the rotatable connection of the feeding shaft 5 allows the baffle 6 to rotate flexibly with the feeding shaft 5, and the speed of the feeding motor 4 can be adjusted. This system can precisely control the feeding speed, preventing a large influx of raw materials into the crushing box 2 at once and causing blockages, ensuring the orderly progress of subsequent crushing and grinding processes. It also reduces frictional wear between the raw materials and the inner wall of the feeding box 3, extending the equipment's service life and improving overall grinding efficiency and raw material utilization. A grinding motor 7 is fixedly installed on the surface of the grinding box 1, and a grinding shaft 8 is fixedly installed inside. A motor frame 9 is fixedly installed at the output end of the grinding motor 7, and a lead screw motor 10 and a sleeve block 11 are fixedly installed on the surface of the motor frame 9. The bottom surface inside the grinding box 1 is arc-shaped, and the inner side of the sleeve block 11 fits against the surface of the lead screw block 13. Here, the rotational power of the grinding motor 7 can be stably transmitted to the lead screw block 13 during equipment operation, thereby driving the grinding roller 14 to rotate around the grinding wheel. The synchronous rotation of shaft 8 ensures that the grinding roller 14 can roll evenly along the arc-shaped bottom surface, grinding the lily raw materials in the box in all directions and avoiding grinding dead angles. The sleeve block 11 can isolate the lead screw 12 from the powder generated during the grinding process, preventing the powder from adhering to the surface of the lead screw 12 and affecting the thread transmission accuracy, effectively protecting the structure of the lead screw 12, reducing equipment failures, extending the service life of the lead screw 12, and ensuring the stable realization of the height adjustment function of the grinding roller 14. The arc-shaped bottom surface improves the overall grinding efficiency and powder uniformity. The lead screw 12 is fixedly installed at the output end of the lead screw motor 10. The surface of the lead screw 12 is threadedly connected to the lead screw block 13. The surface of the lead screw block 13 is rotatably connected to the grinding roller 14. The other end of the grinding roller 14 is rotatably connected to the slide block 15. The surface of the grinding shaft 8... A fixed block 17 is rotatably connected to the grinding roller 14. A slide rod 16 is fixedly mounted on the surface of the fixed block 17. The length of the lead screw 12 and the length of the slide rod 16 are the same and symmetrically distributed on both sides of the grinding roller 14. The surface of the slide rod 16 and the interior of the slide rod block 15 are slidably connected. Here, when the lead screw motor 10 drives the lead screw 12 to rotate, the lead screw block 13 will move along the axial direction of the lead screw 12, and at the same time, the slide rod block 15 will slide synchronously along the slide rod 16. Because the two are the same length and symmetrically distributed, it can ensure that the grinding roller 14 always maintains a horizontal state to adjust the height, and avoid the grinding roller 14 tilting due to uneven force, thereby ensuring that the grinding accuracy of lily raw materials at different positions is consistent. When fine powder is required, the distance between the grinding roller 14 and the bottom surface of the grinding box 1 can be reduced to allow the raw material to be fully ground. When coarse powder is required, the distance can be increased.To meet the needs of different usage scenarios, the sliding cooperation between slide bar 16 and slide block 15 reduces jamming during adjustment and improves the smoothness of equipment operation.

[0024] Example 2

[0025] Please see Figure 5 A crushing motor 18 is fixedly mounted on the surface of the crushing box 2. It drives the driven crushing roller 23 to rotate synchronously via the main shaft 20, shaft belt 21, and driven shaft 22, reducing equipment energy consumption and manufacturing costs. A main crushing roller 19 is fixedly mounted at the output end of the crushing motor 18. The main shaft 20 is fixedly mounted at the other end of the main crushing roller 19. A shaft belt 21 is rolled over the surface of the main shaft 20. A driven shaft 22 is rolled over the inner side of the shaft belt 21. A driven crushing roller 23 is fixedly mounted on the surface of the driven shaft 22. A driven crushing roller 23 is fixedly mounted on the surface of the driven crushing roller 23. The crushing shaft 24, powered by the crushing motor 18, directly drives the main crushing roller 19 to rotate. Simultaneously, the main shaft 20 drives the driven shaft 22 to rotate synchronously via the belt 21. This causes the driven crushing roller 23 to rotate in the opposite direction and at the same speed as the main crushing roller 19. This reduces energy consumption and manufacturing costs while ensuring the coordinated operation of the two crushing rollers. It guarantees that the lily raw material fed into the crushing box 2 is evenly clamped, crushed, and prevents material accumulation or incomplete crushing due to single-roller rotation. The crushing shaft 24 and the crushing box 2... The rotating connection provides stable support for the crushing roller 23, reducing its shaking during rotation and further improving the stability and efficiency of the crushing process. This crushes the lily raw material to a suitable particle size for grinding, effectively reducing the load on subsequent grinding processes. The main crushing roller 19 and the secondary crushing roller 23 are symmetrically distributed on both sides of the crushing box 2. The surface of the crushing shaft 24 and the interior of the crushing box 2 are rotatably connected, allowing the two crushing rollers to form a uniform clamping space. When the lily raw material enters the crushing box 2, it can be simultaneously squeezed and sheared by the two rollers, preventing uneven crushing due to force deviation. Whether the lily raw material is blocky or flaky, a consistent crushing effect can be achieved, effectively reducing large pieces of raw material residue. The crushing shaft 24 not only provides stable rotational support for the secondary crushing roller 23 but also reduces the frictional resistance during rotation, reducing component wear and ensuring that the secondary crushing roller 23 maintains a stable rotational state over a long period. Working in conjunction with the main crushing roller 19, it efficiently completes the crushing operation, supplying uniformly sized raw materials for subsequent grinding processes, further improving the overall processing quality and operational stability of the grinding device.

[0026] Working Principle: When facing the varying needs of different industries for lily powder particle size, it is necessary to adjust the particle size of the lily powder after grinding. This prevents the fine powder from failing to meet the precision requirements when making coarse-grained lily powder for products such as lily cakes and lily porridge in the food industry, thus affecting production efficiency. The lily raw material is fed into the feeding box 3. The feeding motor 4 drives the feeding shaft 5 to rotate, causing the baffle 6 to control the feeding speed through the speed of the feeding motor 4, allowing the raw material to enter the crushing box 2 in an orderly manner. The crushing motor 18 drives the main crushing roller 19 to rotate, and the main rotating shaft 20 drives the auxiliary rotating shaft 22 to rotate synchronously through the rotating shaft belt 21, uniformly squeezing and shearing the raw material. The crushed material falls into the grinding chamber. Grinding box 1, grinding motor 7 is started, and motor frame 9 drives lead screw block 13 and grinding roller 14 to rotate around grinding shaft 8. If the powder coarseness needs to be adjusted, lead screw motor 10 drives lead screw 12 to rotate, lead screw block 13 moves along lead screw 12, and slide block 15 slides synchronously along slide bar 16. Grinding roller 14 maintains horizontal adjustment of the distance between itself and the arc-shaped bottom surface of grinding box 1. The distance is increased when coarse powder is needed and decreased when fine powder is needed. Sleeve block 11 protects lead screw 12 from powder while transmitting the rotation power of grinding motor 7. Finally, grinding roller 14 performs targeted grinding of crushed raw materials to meet the precision requirements of different industries and avoid production efficiency being affected by inconsistent particle size.
