Abstract
Description
Technical Field
[0001] This utility model relates to the field of petal processing technology, specifically a petal crushing and grinding device. Background Technology
[0002] Petal grinding is the process of crushing dried or baked petals into fine powder of 80-120 mesh using tools such as pulverizers and stone mills through high-speed rotation or grinding pressure. Through physical actions such as extrusion and shearing, the fibrous structure of the dried petals is broken down, releasing aromatic substances, pigments, and other components. It is suitable for making petal tea powder, aromatherapy raw materials, natural food additives, etc. It is characterized by simple operation and high component stability. Moreover, because the moisture content of the petals is low (usually <10%), the growth of microorganisms can be avoided during the grinding process. The fine powder after grinding can be directly used to blend beverages, bake flavorings, or as filling for sachets. It is one of the core processes for the deep processing of dried petals.
[0003] Common petal grinders have significant shortcomings in their functional design. They generally lack a built-in screening mechanism, making it impossible to screen the fineness of the material in real time during the grinding process. They can only rely on independent filtration equipment to separate the unevenly sized petal particles after grinding and discharge. This separation method not only requires the purchase of additional filtration devices, increasing equipment investment and subsequent maintenance costs, but also the filtration equipment occupies a large space, resulting in reduced efficiency of production site utilization. At the same time, the processes of manually transferring materials and operating filtration equipment are cumbersome, lengthening the production cycle and seriously affecting processing efficiency. Utility Model Content

It solves the problems of insufficient grinding fineness, cumbersome separation process, high cost, and low efficiency mentioned in the background technology.
[0005] To achieve the aforementioned goals of integrated grinding and screening, high efficiency, and energy saving, this utility model provides the following technical solution: A petal crushing and grinding device includes a crushing and grinding box and a feed inlet installed on the top of the crushing and grinding box. A mounting plate is fixedly connected to the top of the inner cavity of the feed inlet. A motor is mounted on the top of the mounting plate. The output end of the motor passes through the mounting plate and is fixedly connected to a rotating rod. A blade mounting seat is fixedly connected to the upper part of the outer wall of the rotating rod. Evenly distributed blades are mounted on the outer wall of the blade mounting seat. An inner grinding disc is fixedly connected to the lower part of the outer wall of the rotating rod. The lower part of the inner cavity of the grinding box is separately connected to an outer grinding disc, which cooperates with the inner grinding disc. The upper and lower parts of the inner cavity of the grinding box are provided with elastic limiting grooves. The inner cavities of the two elastic limiting grooves are slidably connected to limiting plates. A spring is fixedly connected to one side of the top of the two limiting plates, and the top of the spring is fixedly connected to the top of the inner cavity of the elastic limiting groove. A filter screen is fixedly connected to the middle of the two limiting plates, and the rotating rod passes through the middle of the filter screen. The upper filter screen is located at the bottom of the blade mounting seat, and the lower filter screen is located at the bottom of the inner grinding disc.
[0006] As a further improvement of this utility model: the bottom of each of the two filter screens is fixedly connected to a connecting plate, and the bottom of the two connecting plates is fixedly connected to evenly distributed abutment blocks.
[0007] As a further embodiment of this utility model: the outer wall of the rotating rod is fixedly connected to the lower two sides of the connecting plate one, and the top of the two connecting plates two is fixedly connected to the evenly distributed abutting blocks two, and the abutting blocks two abut against the abutting blocks one.
[0008] As a further improvement of this utility model: a feeding frame is slidably connected through one side of the bottom of the crushing and grinding box, and the feeding frame is located below the lower filter screen.
[0009] As a further improvement of this utility model: a cleaning door is installed through and installed on one side of the lower middle part of the crushing and grinding box, and the cleaning door cooperates with the filter screen at the bottom.
[0010] As a further embodiment of this utility model: the lower part of the rotating rod passes through and has an H-shaped groove, the middle part of the H-shaped groove passes through and is slidably connected to a scraper, the upper and lower sides of the middle part of the scraper are fixedly connected to baffles, and the baffles are located on the left and right sides of the H-shaped groove. The top of the middle part of the H-shaped groove is fixedly connected to a second spring, and the bottom of the second spring is fixedly connected to the scraper.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this utility model, when the rotating rod rotates, the connecting disc two and the contact block two rotate synchronously, forming a clever mechanical linkage. When the contact block two contacts the contact block one, the thrust drives the connecting disc one and the filter screen to move upward. The limiting plate slides along the elastic limiting groove, and the spring one is compressed and stores energy. After the contact is broken, the spring one quickly releases potential energy, causing the filter screen to rebound and shake rapidly, which can produce a high-frequency vibration effect, so that the powder accumulated on the surface of the filter screen and in the mesh is loosened instantly, and cannot form a dense clogging layer. Compared with the traditional static filter screen, this design can improve the screening efficiency and effectively avoid problems such as material accumulation and reduced crushing efficiency caused by filter screen clogging.
[0013] 2. In this utility model, the scraper driven by the rotating rod, in conjunction with the elastic design of the second spring, can always keep close to the surface of the lower filter screen for dynamic cleaning. When the filter screen shakes up and down due to the linkage of the contact block, the scraper and the baffle slide synchronously in the H-shaped groove, ensuring that the scraping action and the vibration of the filter screen are perfectly coordinated. Each rotation of the scraper can thoroughly clean the surface of the filter screen, promptly removing the fine sticky powder generated by grinding and preventing it from forming stubborn stains on the surface of the filter screen. At the same time, the sliding of the baffle in the H-shaped groove blocks fine particles such as pollen from entering the complex internal structure of the device and causing pollution or jamming. This dual protection mechanism not only ensures the cleanliness and permeability of the filter screen, but also significantly extends the service life of the equipment and reduces the frequency and cost of maintenance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-7In this embodiment of the invention, a petal crushing and grinding device includes a crushing and grinding box 1 and a feed inlet 2 installed on the top of the crushing and grinding box 1. A mounting plate 3 is fixedly connected to the top of the inner cavity of the feed inlet 2. A motor 4 is installed on the top of the mounting plate 3. The output end of the motor 4 passes through the mounting plate 3 and is fixedly connected to a rotating rod 6. A blade mounting seat 7 is fixedly connected to the upper part of the outer wall of the rotating rod 6. Evenly distributed blades 5 are installed on the outer wall of the blade mounting seat 7. During operation, dried petals are fed into the crushing and grinding box 1 through the feed inlet 2. Due to the unique angled design of the blade mounting seat 7, the petals slide smoothly to both sides. Simultaneously with feeding, the motor 4 is started, driving the rotating rod 6 to rotate at high speed, causing the blade mounting seat 7 and the sharp blades 5 to rotate synchronously. The blades 5 first... The intact petals undergo initial crushing, and the crushed petals fall onto the upper filter screen 13. At this point, the upper filter screen 13 begins to function as a sieving device, allowing petal fragments that meet the particle size requirements to pass through smoothly, while larger fragments that do not meet the standard are intercepted and remain on the filter screen 13 for secondary crushing by the blades 5. An inner grinding disc 9 is fixedly connected to the lower part of the outer wall of the rotating rod 6, and an outer grinding disc 8 is separately connected to the lower part of the inner cavity of the crushing and grinding box 1. The outer grinding disc 8 cooperates with the inner grinding disc 9. The petal fragments that have completed the initial sieving move downwards and arrive at the grinding area formed by the outer grinding disc 8 and the inner grinding disc 9. The rotational power of the rotating rod 6 is synchronously transmitted to the inner grinding disc 9, causing it to rotate at high speed. The inner grinding disc 9 and the fixed outer grinding disc 8 are tightly fitted together, and through compression and grinding... Through multiple processes, the petal fragments are finely ground into a fine powder. The ground material is then filtered again through the lower filter screen 13. The qualified powder falls into the feeding frame 23 for centralized collection. The inner cavity of the crushing and grinding box 1 is provided with elastic limiting grooves 10 at both the upper and lower parts. The inner cavities of the two elastic limiting grooves 10 are slidably connected to limiting plates 11. Springs 12 are fixedly connected to one side of the top of the two limiting plates 11, and the top of the springs 12 is fixedly connected to the top of the inner cavity of the elastic limiting grooves 10. Filter screens 13 are fixedly connected to the middle of the two limiting plates 11, and the rotating rod 6 passes through the middle of the filter screens 13. The upper filter screen 13 is located at the bottom of the blade mounting seat 7, and the lower filter screen 13 is located at the bottom of the inner grinding disc 9. The bottom of the two filter screens 13 is fixedly connected to a connecting rod. The bottom of the two connecting plates 18 is fixedly connected with evenly distributed abutment blocks 19. The outer wall of the rotating rod 6 is fixedly connected to two connecting plates 20 on both sides of the lower part of the connecting plates 18. The top of each of the two connecting plates 20 is fixedly connected with evenly distributed abutment blocks 21, which abut against the abutment blocks 19. A feeding frame 23 is slidably connected through one side of the bottom of the grinding and crushing box 1, and the feeding frame 23 is located below the lower filter screen 13. When the rotating rod 6 rotates, it not only drives the grinding and crushing components but also drives the connecting plates 20 and the abutment blocks 21 to rotate synchronously. When the abutment blocks 21 contact the abutment blocks 19, the resulting thrust causes the connecting plates 18 and the filter screen 13 to move upwards. During this process…The limiting plate 11 slides upward along the elastic limiting groove 10, and the spring 12 is compressed and stores energy. When the second contact block 21 disengages from the first contact block 19, the spring 12 quickly releases its elastic potential energy, causing the limiting plate 11 and the filter screen 13 to rebound rapidly, producing a shaking effect. This effectively prevents the filter screen 13 from clogging due to powder accumulation, ensuring a smooth and unobstructed screening process.
[0024] A cleaning door 22 is installed through and installed on one side of the middle and lower part of the crushing and grinding box 1. The cleaning door 22 is matched with the filter screen 13 at the bottom. If necessary, the cleaning door 22 can be opened at any time to clean the unqualified materials trapped by the lower filter screen 13, ensuring the continuous and efficient operation of the device.
[0025] The lower part of the rotating rod 6 has an H-shaped groove 14. A scraper 15 is slidably connected through the middle of the H-shaped groove 14. Baffles 17 are fixedly connected to the upper and lower sides of the middle of the scraper 15, and the baffles 17 are located on the left and right sides of the H-shaped groove 14. A spring 16 is fixedly connected to the top of the middle of the H-shaped groove 14, and the bottom of the spring 16 is fixedly connected to the scraper 15. The rotating rod 6 also drives the scraper 15 to rotate, continuously scraping and cleaning the surface of the lower filter screen 13. The scraper 15 is tightly attached to the surface of the filter screen 13 by the elastic force of the spring 16. When the lower filter screen 13 shakes up and down due to the interaction between the second contact block 21 and the first contact block 19, the scraper 15 and the baffles 17 will slide synchronously in the H-shaped groove 14 to ensure that the scraper 15 is always in close contact with the filter screen 13, achieving efficient cleaning. The sliding of the baffles 17 in the H-shaped groove 14 can also effectively prevent the ground pollen from entering the H-shaped groove 14, keeping the inside of the device clean.
[0026] The working principle of this utility model is as follows: During operation, the dried petals are fed into the crushing and grinding box 1 through the feed inlet 2. Due to the unique angled design of the blade mounting seat 7, the petals slide to both sides. At the same time as feeding, the motor 4 is started. The motor 4 drives the rotating rod 6 to rotate at high speed, which drives the blade mounting seat 7 and the sharp blade 5 to rotate synchronously. The blade 5 first crushes the complete petals. The crushed petals then fall to the upper filter screen 13. At this time, the upper filter screen 13 begins to play a screening role. Petal fragments that meet the particle size requirements pass through smoothly, while larger fragments that do not meet the standard are intercepted and continue to remain on the filter screen 13 to receive secondary crushing treatment by the blade 5.
[0027] Among them, the blade mounting base 7 and the inner grinding disc 9 are designed as hollow structures, which can effectively reduce the load and energy consumption of the motor 4.
[0028] After the initial screening, the petal fragments move downwards and arrive at the grinding area formed by the outer grinding disc 8 and the inner grinding disc 9. The rotational power of the rotating rod 6 is synchronously transmitted to the inner grinding disc 9, causing it to rotate at high speed. The inner grinding disc 9 and the fixed outer grinding disc 8 are closely matched. Through multiple actions such as squeezing and grinding, the petal fragments are finely ground into fine powder. The ground material is filtered again through the lower filter screen 13, and the qualified powder falls into the feeding frame 23 for centralized collection.
[0029] When the rotating rod 6 rotates, it not only drives the crushing and grinding components to work, but also drives the connecting plate 20 and the contact block 21 to rotate synchronously. When the contact block 21 contacts the contact block 19, the resulting thrust drives the connecting plate 18 and the filter screen 13 to move upward. During this process, the limiting plate 11 slides upward along the elastic limiting groove 10, and the spring 12 is compressed and stores energy. When the contact block 21 and the contact block 19 disengage, the spring 12 quickly releases its elastic potential energy, causing the limiting plate 11 and the filter screen 13 to rebound quickly, producing a shaking effect. This effectively prevents the filter screen 13 from clogging due to powder accumulation, ensuring a smooth and unobstructed screening process.
[0030] At the same time, the rotating rod 6 also drives the scraper 15 to rotate, continuously scraping and cleaning the surface of the lower filter screen 13. The scraper 15 is tightly attached to the surface of the filter screen 13 by the elastic force of the second spring 16. When the lower filter screen 13 shakes up and down due to the interaction between the second contact block 21 and the first contact block 19, the scraper 15 and the baffle 17 will slide synchronously in the H-shaped groove 14 to ensure that the scraper 15 is always in close contact with the filter screen 13, achieving efficient cleaning. The sliding of the baffle 17 in the H-shaped groove 14 can also effectively prevent the ground pollen from entering the H-shaped groove 14, keeping the inside of the device clean. If necessary, the cleaning door 22 can be opened at any time to clean the unqualified materials trapped by the lower filter screen 13, ensuring the continuous and efficient operation of the device.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
