Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rice noodle processing technology, specifically relating to a pulverizing device for rice noodle processing. Background Technology
[0002] Rice noodles are made primarily from rice, with some regions adding sweet potato starch and potato starch during production. This results in differences in taste and storage compared to rice vermicelli. During rice noodle processing, substandard rice noodles need to be crushed and recycled, requiring crushing equipment. Existing roller crushing equipment often results in rice noodles getting stuck between the crushing blades after being crushed by the two rollers. The gap between the rollers is insufficient to remove the stuck rice noodles, causing them to easily spoil due to prolonged retention. Spoiled rice noodles not only contaminate subsequent materials but can also lead to microbial growth, corrosion of equipment components, and reduced equipment lifespan. Utility Model Content
[0003] The purpose of this invention is to provide a rice noodle pulverizing device, aiming to solve the problem in existing roller pulverizing equipment where rice noodles often get stuck between the roller pulverizing blades after being pulverized by the two rollers. The distance between the rollers is insufficient to remove the stuck rice noodles, causing them to easily deteriorate due to prolonged retention. Deteriorated rice noodles not only contaminate subsequent materials being pulverized but may also lead to microbial growth, corrosion of equipment components, and reduced equipment lifespan.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a pulverizing device for rice noodle processing, comprising a pulverizing metal box, a pulverizing mechanism installed on the inner wall of the pulverizing metal box, a feeding structure assembled inside the pulverizing metal box, a support leg connected to the bottom end of the pulverizing metal box, two symmetrical fixing blocks connected to the outer wall of the pulverizing metal box, a bidirectional threaded rod connected between the two fixing blocks, a first motor assembled at the front end of one of the fixing blocks, a threaded sleeve threadedly connected to the surface of the bidirectional threaded rod, a scraper connected to the inner side wall of the threaded sleeve, and a protective shell connected to the outer wall of the pulverizing metal box.
[0005] As a preferred embodiment of the rice noodle processing crushing equipment of this utility model, the bidirectional threaded rod can be rotatably connected to the fixed block through a bearing.
[0006] As a preferred embodiment of the rice noodle processing crushing equipment of this utility model, the output shaft of the first motor is fixedly connected to one end of the bidirectional threaded rod.
[0007] As a preferred embodiment of the rice noodle processing crushing equipment of this utility model, the protrusions on the surface of the scraper are staggered with the crushing blades of the crushing mechanism rollers.
[0008] As a preferred embodiment of the rice noodle processing crushing equipment of this utility model, the bottom end of the crushing metal box is connected to a discharge hopper, and the discharge hopper is provided with a first filter screen and a second filter screen. A bolt is connected to one side of the second filter screen, and the second filter screen can be detachably and fixedly connected to the discharge hopper by the bolt.
[0009] As a preferred embodiment of the rice noodle processing crushing equipment of this utility model, a connecting block is connected to one side of the first filter screen, an electric rod is installed on the side wall of the discharge hopper, the connecting block is connected to the telescopic end of the electric rod by screws, and a protective shell is connected to the outer side wall of the discharge hopper.
[0010] As a preferred embodiment of the rice noodle processing crushing equipment of this utility model, the bottom end of the first filter screen is provided with a "T"-shaped sliding groove, and a slider is adapted to be connected inside the sliding groove. The slider is connected to the second filter screen, and the first filter screen can be slidably connected to the second filter screen through the slider and the sliding groove. A sealing gasket is connected at the connection between the discharge hopper and the first and second filter screens.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] The scraper, threaded sleeve, bidirectional threaded rod, and first motor work together to move the scraper closer to the crushing mechanism's rollers. Simultaneously, the protrusions on the scraper are staggered with the crushing blades of the rollers. This removes rice flour stuck between the two crushing blades on the rotating rollers without affecting the crushing mechanism, preventing residual rice flour from easily spoiling due to prolonged retention. Spoiled rice flour not only contaminates subsequent materials but can also lead to microbial growth, corrosion of equipment components, and reduced equipment lifespan.
[0013] Through the cooperation of the electric rod and the connecting block, the first filter screen can move in close contact with the top surface of the second filter screen. The upper first filter screen with a smaller mesh size acts as a preliminary screening layer, effectively intercepting most of the larger particles, significantly reducing the screening burden on the lower second filter screen, thereby improving the overall screening efficiency. Secondly, the lower second filter screen with a larger mesh size can quickly release small particles that meet the standards, avoiding the problem of these small particles remaining and clogging for a long time on a single filter screen with a smaller mesh size. This further improves the uniformity of the rice flour output after grinding. Attached Figure Description

[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 1-6 The present invention provides the following technical solution: a crushing device for rice noodle processing, comprising a crushing metal box 1, a crushing mechanism 2 installed on the inner wall of the crushing metal box 1, a feeding structure 3 assembled inside the crushing metal box 1, a support leg 4 connected to the bottom end of the crushing metal box 1, two symmetrical fixing blocks 6 connected to the outer wall of the crushing metal box 1, a bidirectional threaded rod 7 connected between the two fixing blocks 6, a first motor 8 assembled at the front end of one of the fixing blocks 6, a threaded sleeve 10 threadedly connected to the surface of the bidirectional threaded rod 7, a scraper 9 connected to the inner wall of the threaded sleeve 10, and a protective shell 11 connected to the outer wall of the crushing metal box 1.
[0024] Preferably, the bidirectional threaded rod 7 can be rotatably connected to the fixed block 6 via a bearing.
[0025] In practical use, during the rotation of the bidirectional threaded rod 7, it can rotate stably between the two fixed blocks 6 along the inner ring of the bearing. Simultaneously, the threaded sleeve 10 is restricted by the scraper 9, moving along the threads on the surface of the bidirectional threaded rod 7. This prevents the threaded sleeve 10 from rotating with the bidirectional threaded rod 7. Consequently, the threaded sleeve 10 can drive the scraper 9 closer to the crushing mechanism 2, removing the rice flour stuck between the two crushing blades on the rotating roller. This prevents the residual rice flour from easily deteriorating due to prolonged retention. Deteriorated rice flour not only contaminates subsequently fed materials to be crushed but may also lead to microbial growth, corrosion of equipment components, and reduced equipment lifespan.
[0026] Preferably, the output shaft of the first motor 8 is fixedly connected to one end of the bidirectional threaded rod 7.
[0027] In practical use, when the first motor 8 is connected to the power supply and started, its output shaft can drive the bidirectional threaded rod 7 to rotate. Thus, the rotation of the bidirectional threaded rod 7 drives the threaded sleeve 10 and the scraper 9 to move together, realizing the convenience of the scraper 9 moving closer to the crushing mechanism 2.
[0028] Preferably, the protrusions on the surface of the scraper 9 are staggered with the crushing blades of the rollers of the crushing mechanism 2.
[0029] In practical use, when the scraper 9 approaches the crushing mechanism 2 through the threaded sleeve 10, it will not collide with the crushing blade on the crushing mechanism 2, thus ensuring the stable operation of the crushing mechanism 2. The crushing mechanism 2 is composed of two servo motors and rollers. The two rollers rotate in opposite directions through the operation of the servo motors, so that when the rice noodles are fed from the crushing metal box 1, the crushing mechanism 2 can crush the rice noodles.
[0030] Preferably, the bottom of the metal crushing box 1 is connected to a discharge hopper 5, and the discharge hopper 5 is provided with a first filter screen 12 and a second filter screen 13. A bolt 15 is connected to one side of the second filter screen 13, and the second filter screen 13 can be detachably and fixedly connected to the discharge hopper 5 by the bolt 15.
[0031] In practical use, when the rice noodles are fed to the discharge hopper 5 through the feeding structure 3, the pulverized rice noodles fall onto the first filter screen 12 through the discharge hopper 5. Then, the first filter screen 12 can move closely against the top surface of the second filter screen 13. The upper first filter screen 12 with a smaller mesh opening acts as a preliminary screening layer, effectively intercepting most of the larger particles, significantly reducing the screening burden on the lower second filter screen 13, thereby improving the overall screening efficiency. Secondly, the lower second filter screen 13 with a larger mesh opening can quickly release small particles that meet the standards, avoiding the problem of these small particles remaining and clogging on a single filter screen with a smaller mesh opening for a long time. This improves the uniformity of the rice noodles after pulverization. The movement of the first filter screen 12 and the cooperation of the second filter screen 13 can also form a secondary clamping effect on the long strips of incompletely pulverized rice noodles.
[0032] In addition, the feeding structure 3 is composed of a stepper motor and a auger. When the stepper motor starts the auger to rotate, the rice noodles that fall to the bottom of the crushing metal box 1 through the crushing mechanism 2 will be evenly fed to the discharge hopper 5 by the feeding structure 3, and then sent out from the discharge hopper 5 to the outside.
[0033] Next, when removing bolt 15, the connection between the second filter screen 13 and the discharge hopper 5 can be released, making it easier to loosen the second filter screen 13 so that the first filter screen 12 can be manually removed and the two filter screens can be taken out for cleaning.
[0034] Preferably, a docking block 16 is connected to one side of the first filter screen 12, an electric rod 17 is installed on the side wall of the discharge hopper 5, the docking block 16 is connected to the telescopic end of the electric rod 17 by screws, and a protective shell 18 is connected to the outer side wall of the discharge hopper 5.
[0035] In actual use, the electric rod 17 is manually started by connecting it to a power source. The telescopic end of the electric rod 17 quickly extends and retracts, causing the first filter screen 12 to move and tightly adhere to the top surface of the second filter screen 13. This allows the movable first filter screen 12 to perform a sieving function, preventing rice flour from accumulating on it.
[0036] Next, manually remove the screws to disconnect the connection between the connecting block 16 and the telescopic end of the electric rod 17. Then, with the removal of the bolt 15, release the fixation of the second filter screen 13. This allows the two filter screens to be removed from the inside of the discharge hopper 5, making it easier to clean the first filter screen 12 and the second filter screen 13 and preventing the screen openings from becoming clogged.
[0037] Preferably, the bottom end of the first filter screen 12 is provided with a "T"-shaped groove 20, and a slider 19 is adapted to be connected inside the groove 20. The slider 19 is connected to the second filter screen 13. The first filter screen 12 can be slidably connected to the second filter screen 13 through the slider 19 and the groove 20. A sealing gasket 14 is connected at the connection between the discharge hopper 5 and the first filter screen 12 and the second filter screen 13.
[0038] In practical use, when the first filter screen 12 and the second filter screen 13 are assembled inside the discharge hopper 5, their sealing gaskets 14 can effectively seal the gaps connecting the first filter screen 12 and the second filter screen 13 to the discharge hopper 5, preventing rice flour from seeping in through the gaps. Subsequently, the sliding engagement of the slider 19 and the slide groove 20 ensures that the first filter screen 12 slides smoothly and stably on top of the second filter screen 13. The distance the first filter screen 12 moves out will not exceed two grids of the opening of the second filter screen 13.
[0039] Working principle: First, the first motor 8 is manually connected to the power supply and started. Its output shaft rotates stably between the two fixed blocks 6 along the inner ring of the bearing. Then, the threaded sleeve 10 is restricted by the scraper 9 and moves along the threads on the surface of the bidirectional threaded rod 7. Subsequently, the threaded sleeve 10 drives the scraper 9 to approach the crushing mechanism 2. Then, the electric rod 17 is manually connected to the power supply and started. The telescopic end of the electric rod 17 quickly extends and retracts, thereby driving the first filter screen 12 to move tightly against the top surface of the second filter screen 13. Then, rice noodles are fed from the crushing metal box 1 and fall into the crushing mechanism 2. The crushing mechanism 2 then crushes the rice noodles. At the same time, the protrusions on the scraper 9 and the crushing blades of the rollers are staggered. In this way, without affecting the crushing mechanism 2, the rice noodles stuck between the two crushing blades on the rollers are removed, preventing these residual rice noodles from easily deteriorating due to long-term retention. Spoiled rice noodles not only contaminate subsequent materials to be ground, but may also lead to microbial growth, corrosion of equipment parts, and reduced equipment lifespan. The ground rice noodles fall to the bottom of the grinding metal box 1 and are then fed to the discharge hopper 5 by the feeding structure 3. Next, the ground rice noodles fall onto the first filter screen 12 along the discharge hopper 5. The movement of the first filter screen 12 then sieving the rice noodles. The upper, smaller-aperture first filter screen 12 acts as a preliminary screening layer, effectively intercepting most of the larger particles, significantly reducing the sieving burden on the lower, second-aperture filter screen 13, thereby improving overall sieving efficiency. Furthermore, the lower, larger-aperture second filter screen 13 can quickly release rice noodles that meet the standards, avoiding the problem of prolonged retention and clogging on a single filter screen with a smaller opening. This further improves the uniformity of the rice noodles after grinding.
[0040] It is worth noting that: the protective housing 11 is connected to the crushing metal box 1 by screws, and the protective housing 18 is connected to the discharge hopper 5 by screws. Both the protective housing 11 and 18 are made of metal and protect the first motor 8 and the electric rod 17. Openings are provided on both the protective housing 11 and 18 for heat dissipation of the first motor 8 and the electric rod 17, ensuring the efficiency of their operation.
[0041] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
