Description

Technical Field

[0001] This utility model relates to the field of rice noodle processing technology, and in particular to a pulverizing device for rice noodle processing. Background Technology

[0002] In the rice noodle processing technology, the crushing process is one of the key steps that affects the quality of the finished product. Its main function is to crush raw materials such as dry rice noodles and rice noodle blocks into uniform particle size, so as to provide the basic materials that meet the requirements for subsequent mixing, shaping or reprocessing.

[0003] Currently, most mainstream pulverizing devices use high-speed hammer mills, which cannot pulverize rice noodles into finer particles, requiring secondary processing, which is time-consuming and labor-intensive. Furthermore, if the raw materials contain damp, clump-forming rice noodles, direct entry into the pulverizing chamber can easily cause blockages at the feed inlet, necessitating frequent shutdowns for cleaning and impacting processing efficiency.

[0004] Chinese patent document CN215312875U discloses a pulverizing device for rice flour processing capable of uniform pulverization, including a transport channel and a pulverizing shell. A motor A is installed on one outer wall of the soaking tank, and a motor B is installed on the other outer wall. A threaded rod A is installed at the output end of motor A, and a pushing block A is installed on the outer wall of the threaded rod A. An auxiliary sliding rod A is installed on the outer wall of the pushing block A. A threaded rod B is installed at the output end of motor B, and a pushing block B is installed on the outer wall of the threaded rod B. This invention, through the installation of a soaking device, involves pouring rice into water for soaking. After a suitable time, the water is drained. Motor C rotates, driving gear A, which in turn drives a gear connecting rod upwards. The gear connecting rod lifts a baffle upwards. The rotation of motors A and B drives the threaded connecting rod to rotate, pushing the baffle forward and propelling the rice from the soaking tank into the transport channel. The soaked rice is then automatically poured into the pulverizing device.

[0005] However, the above-mentioned patent documents still have the following defects in implementation: the device is equipped with 7 independent motors, which consumes a lot of energy; the soaked rice powder is easy to stick to the powdering blade and inner wall, and there is no cleaning mechanism, so it is necessary to stop the machine for operation.

[0006] Therefore, we propose a pulverizing device for rice noodle processing to solve the above problems. Utility Model Content

[0007] The main objective of this invention is to provide a pulverizing device for rice noodle processing, which can effectively solve the problems mentioned above.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A crushing device for rice noodle processing includes a base, on which a motor is mounted. A pulley is mounted on the output end of the motor via a coupling. The pulley is rotatably connected to a primary crushing device and a moving blade crushing mechanism. A feeding mechanism is fixedly connected to the upper end of the primary crushing device, and a collecting device is mounted at the lower end of the moving blade crushing mechanism. The discharge port of the primary crushing device is connected to the feed port of the moving blade crushing mechanism.

[0009] Preferably, the feeding mechanism includes a feeding hopper, with two metal plates rotatably connected to the front and rear sides of the inside of the feeding hopper. An arc-shaped hole is provided on the left side of the feeding hopper, and handles are installed on the side of the two metal plates near the arc-shaped hole. One end of each of the two handles extends through the arc-shaped hole to the outside of the feeding hopper.

[0010] Preferably, the primary crushing device includes a primary crushing box and a metal rod. Two crushing rollers are installed inside the primary crushing box. The two crushing rollers mesh with each other and have a gap. Gears are installed on the same side of both crushing rollers. The two gears mesh with each other. The metal rod is rotatably connected to one of the crushing rollers through a bearing. A second pulley is installed on one side of the metal rod. The second pulley is rotatably connected to the first pulley through a belt.

[0011] Preferably, the moving blade crushing mechanism includes a crushing outer cavity and a crushing inner cavity. The crushing inner cavity is a circular structure and is located inside the crushing outer cavity and fixedly connected to the crushing outer cavity. The lower part of the crushing inner cavity has several small holes. A rotating shaft is rotatably connected inside the crushing outer cavity. A moving blade assembly is installed on the rotating shaft. A pulley is installed at the end of the rotating shaft away from the crushing outer cavity. The pulley is rotatably connected to the pulley through a belt.

[0012] Preferably, the moving blade assembly includes several serrated blades, several narrow-bladed blades, and several wide-bladed blades. Multiple serrated blades form a serrated blade group, multiple narrow-bladed blades form a narrow-bladed blade group, and multiple wide-bladed blades form a wide-bladed blade group. These groups of serrated blades, narrow blades, and wide blades are arranged in an array along the long axis of the rotation axis. Several columns of serrated blade groups, narrow-bladed blade groups, and wide-bladed blade groups are spaced apart along the circumference of the rotation axis. In the gaps between each serrated blade group, a brush is installed on the side where two serrated blades are close to each other. Similarly, in the gaps between each narrow-bladed blade group, a brush is installed on the side where two narrow-bladed blades are close to each other. In the gaps between each wide-bladed blade group, a brush is installed on the side where two wide-bladed blades are close to each other.

[0013] Preferably, the collecting device includes a collecting hopper, a material transfer cylinder is installed at the lower part of the collecting hopper, a rotating shaft two is installed inside the material transfer cylinder, a spiral blade is installed on the outer surface of the rotating shaft two, a pulley four is installed on one side of the rotating shaft two, the pulley four is rotatably connected to the pulley three via a belt three, and a discharge cylinder is installed on the side of the discharge cylinder away from the pulley four.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This device achieves flexible control of the feeding speed through a rotatable metal plate inside the hopper and a handle extending to the outside, preventing the primary crushing device from being blocked due to excessively fast feeding of raw materials and ensuring continuous processing. This device uses two meshing crushing rollers in the primary crushing unit to rotate in opposite directions under gear transmission to pre-crush the raw materials. This not only breaks up the damp and clumped rice noodles, but also eliminates the need for an additional power source, reducing energy consumption and lightening the load on the subsequent moving blade crushing mechanism. This device utilizes a graded crushing structure formed by wide-bladed, narrow-bladed, and serrated blades to achieve step-by-step crushing from coarse to fine, ensuring uniform rice noodle particle size. Simultaneously, the brush rotates synchronously with the moving blades, which can lift up residual materials for further crushing, avoiding downtime for cleaning due to residue on the inner wall and improving processing efficiency.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Example 1, as Figure 1 As shown, a rice noodle processing crushing device includes a base 1, on which a motor 3 is mounted. The output end of the motor 3 is connected to a pulley 2 via a coupling. The pulley 2 drives the motor 3 to rotate. The pulley 2 is rotatably connected to a primary crushing device 5 and a moving blade crushing mechanism 6. The upper end of the primary crushing device 5 is fixedly connected to a feeding mechanism 4. The lower end of the moving blade crushing mechanism 6 is equipped with a collecting device 7. The discharge port of the primary crushing device 5 is connected to the feed port of the moving blade crushing mechanism 6.

[0019] For further details, please refer to [link / reference]. Figure 1 and Figure 2 The moving blade crushing mechanism 6 supports the primary crushing device 5 and the feeding mechanism 4. The moving blade crushing mechanism 6 is fixed by the bracket of the base 1, ensuring the stability of the above three mechanisms and preventing them from falling off due to vibration during the crushing process. The feed inlet of the moving blade crushing mechanism 6 is designed with an inclination, and the inner wall of the moving blade crushing mechanism 6 is smoothed to facilitate the sliding of raw materials.

[0020] Furthermore, such as Figure 1 and Figure 2 As shown, the feeding mechanism 4 includes a feeding hopper 41. Two metal plates 42 are rotatably connected to the front and rear sides of the inside of the feeding hopper 41. An arc-shaped hole is opened on the left side of the feeding hopper 41. A handle 43 is installed on the side of the two metal plates 42 near the arc-shaped hole. One end of each handle 43 extends through the arc-shaped hole to the outside of the feeding hopper 41. The rice to be crushed is put into the feeding mechanism 4 manually or by instruments. At this time, the opening and closing size of the two metal plates 42 can be controlled by rotating the metal plates 42 along the arc-shaped hole on the feeding hopper 41 through the handle 43, thereby controlling the feeding speed.

[0021] For further details, please refer to [link / reference]. Figure 3The primary crushing device 5 includes a primary crushing box 51 and a metal rod 54. Two crushing rollers 52 are installed inside the primary crushing box 51. The two crushing rollers 52 mesh with each other and have gaps. Gears 53 are installed on the same side of the two crushing rollers 52. The two gears 53 mesh with each other. The metal rod 54 is rotatably connected to one of the crushing rollers 52 through a bearing. A second pulley 55 is installed on one side of the metal rod 54. The second pulley 55 is rotatably connected to the first pulley 2 through a first belt.

[0022] Specifically, during implementation, when the rice raw material enters the primary crushing device 5 through the feeding mechanism 4, the starting motor 3 drives pulley 2 to rotate. Since pulley 2 and pulley 55 are connected by a belt, pulley 55 is driven by pulley 2, which in turn drives one of the crushing rollers 52 to rotate via the metal rod 54. At this time, due to the meshing of the two gears 53 installed on the two crushing rollers 52, the other crushing roller 52 is also driven. The two crushing rollers 52 mesh and rotate, performing primary pre-crushing of the rice raw material and breaking up washed or damp and clump-like rice raw material, preventing large pieces of material from directly entering the crushing chamber and causing blockage, while also reducing the load on the main crushing mechanism. The power of the two crushing rollers 52 is distributed from the power output of the motor 3 through pulley 2, requiring no additional power source.

[0023] In implementation, the operator feeds the rice flour raw material into the feed hopper 41 and adjusts the opening angle of the two metal plates 42 by rotating the handle 43 along the arc-shaped hole to control the feeding speed. After the raw material falls into the primary crushing box 51 of the primary crushing device 5, the motor 3 drives the pulley 2 to rotate, which in turn drives the pulley 55 to rotate. The pulley 55 drives one of the crushing rollers 52 to rotate via the metal rod 54, and then the other crushing roller 52 is linked by the meshing gear 53. The two crushing rollers 52 perform primary crushing of the raw material with a meshing gap, especially for damp and lumpy materials, breaking them down into coarse particles to avoid clogging the subsequent moving blade crushing mechanism 6. The crushed material falls directly into the inclined feed inlet of the moving blade crushing mechanism 6 through the discharge port at the bottom of the primary crushing box 51, and its smooth inner wall ensures that no material residue slips off.

[0024] Example 2, as Figure 4 and Figure 5 As shown, the moving blade crushing mechanism 6 includes a crushing outer cavity 61 and a crushing inner cavity 62. The crushing inner cavity 62 is a circular structure and is located inside the crushing outer cavity 61 and is fixedly connected to the crushing outer cavity 61. Several small holes are opened in the lower part of the crushing inner cavity 62. The crushed rice flour falls through the holes and enters the collecting device 7 for collection. A rotating shaft 64 is rotatably connected inside the crushing outer cavity 61. A moving blade assembly 63 is installed on the rotating shaft 64. A pulley 65 is installed at the end of the rotating shaft 64 away from the crushing outer cavity 61. The pulley 65 is rotatably connected to the pulley 2 via a belt.

[0025] Specifically, when motor 3 drives pulley 2 to rotate, the rotation of pulley 2 will drive pulley 3 65 to rotate, thus ensuring that the moving blade assembly 63 moves rapidly in a circular motion around the rotating shaft 64, further crushing the initially crushed rice or some of the raw materials that have become rice flour, thereby achieving finer particles.

[0026] Furthermore, such as Figure 6 as well as Figure 8 As shown, the moving blade assembly 63 includes several serrated blades 632, several narrow-bladed blades 633, and several narrow-bladed blades 634. The multiple serrated blades 632 form a serrated blade assembly, the multiple narrow-bladed blades 633 form a narrow-bladed blade assembly, and the multiple wide-bladed blades 634 form a wide-bladed blade assembly. The multiple serrated blades, narrow-bladed blades, and wide-bladed blades form an array along the long axis of the rotation axis 64. The multiple rows of serrated blade assemblies, narrow-bladed blade assemblies, and wide-bladed blade assemblies are spaced apart along the circumferential direction of the rotation axis 64. In the gaps between each serrated blade assembly, a brush 631 is installed on the side where two serrated blades 632 are close to each other. In the gaps between each narrow-bladed blade assembly, a brush 631 is installed on the side where two narrow-bladed blades 633 are close to each other. In the gaps between each wide-bladed blade assembly, a brush 631 is installed on the side where two wide-bladed blades 634 are close to each other.

[0027] Specifically, the wide blade of the 634 blade, with its large contact area and low angle, can quickly apply impact and shearing forces to large pieces of raw material, achieving coarse crushing and providing a foundation for subsequent fine processing; the narrow blade of the 633 blade, with its sharper edge and moderate contact area, performs secondary shearing on the coarsely crushed material, refining the particle size to medium; the serrated blade of the 632 blade, with its fine tooth structure, increases the contact points with the material, and through high-frequency shearing and friction, further crushes medium particles to fine particles, ultimately achieving a step-by-step crushing process from coarse to fine, ensuring uniform product particle size.

[0028] In addition, since some raw materials or coarse powder after being crushed do not pass through the holes of the crushing chamber 62, they can be carried up by the rotating brush 631 and further crushed by the passive blade until they pass through the holes and enter the collection device 7, thus avoiding dead corners or residue on the inner wall.

[0029] When the rotating shaft rotates, the three sets of moving blades rotate synchronously at high speed with the shaft. After the raw material enters the crushing chamber, the narrow blades 633 of the wide blade group impact and shear the raw material through their cutting edges during rotation, breaking large pieces of raw material into coarse particles. The sharp-angled cutting edges of the serrated blades 632 of the narrow blade group generate stronger local shearing force, further crushing the coarse particles into medium-sized particles. The fine teeth of the brushes 631 of the serrated blade group come into high-frequency contact with the material during rotation. Through the cutting and friction between the teeth, the material is refined to the target fine particle size, and finally the grading and crushing process is completed.

[0030] In summary, based on Example 1, this embodiment involves the initial crushing of the raw material into a crushing chamber composed of the outer crushing chamber 61 and the inner crushing chamber 62. Motor 3 drives pulley 65 via belt 2, causing rotating shaft 64 to rotate at high speed. The moving blade assembly 63 mounted on rotating shaft 64 operates synchronously, performing three-stage crushing: large pieces of raw material are subjected to impact shearing with a wide blade edge for coarse crushing; coarse particles are further refined to medium size through secondary shearing with a narrow blade edge; and finally, high-frequency friction cutting with a fine toothed structure achieves the target fineness.

[0031] Brushes 631 installed between each set of blades sweep away powder adhering to the wall of the crushing chamber 62 during rotation, bringing it back to the crushing area for secondary processing. Qualified fine powder falls into the collection device 7 through small holes at the bottom of the crushing chamber 62, while substandard particles continue to be circulated and crushed.

[0032] Example 3, as Figure 7 As shown, the collecting device 7 includes a collecting hopper 73, a material transfer cylinder 72 is installed at the lower part of the collecting hopper 73, a rotating shaft 74 is installed inside the material transfer cylinder 72, a spiral blade 75 is installed on the outer surface of the rotating shaft 74, a pulley 76 is installed on one side of the rotating shaft 74, and the pulley 76 is rotatably connected to the pulley 65 via a belt. A discharge cylinder 71 is installed on the side of the material transfer cylinder 72 away from the pulley 76.

[0033] The crushed rice flour enters the collection hopper 73 and flows along the inclined inner wall of the collection hopper 73 into the conveyor cylinder 72. Due to the rotation of the pulley 65, the pulley 76 connected to it will also rotate continuously, driving the rotating shaft 74 and the spiral blade 75 to rotate. The rotation of the spiral blade 75 will drive the rice flour in the conveyor cylinder 72 to move towards the discharge cylinder 71, and then be collected into other containers for further processing.

[0034] In implementation, this embodiment, based on Embodiments 1 and 2, involves fine powder falling into the collecting hopper 73 through the holes in the crushing chamber 62, and then sliding along its inclined inner wall into the conveyor cylinder 72. Belt pulley 3 65 drives belt pulley 4 76 via belt 3, causing the rotating shaft 2 74 to rotate. The spiral blades 75 mounted on the rotating shaft 2 74 continuously push the powder towards the discharge cylinder 71, achieving automatic discharge. The connection design between the conveyor cylinder 72 and the discharge cylinder 71 ensures no powder retention, allowing direct connection to downstream packaging or processing equipment.

[0035] It should be noted that the specific installation method, circuit connection method, and control method of the motor 3 and other components used in this utility model are all conventional designs, and will not be described in detail here.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
