Description

Technical Field

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

[0002] In the rice noodle processing, screening is a crucial step in ensuring product quality uniformity. Freshly produced rice noodles often have inconsistent shapes and may contain clumps, rice noodle segments that do not meet the standard length or thickness, or even small amounts of impurities. If these substandard rice noodles are directly introduced into the subsequent packaging or sales stages, it will seriously affect the product quality and market competitiveness.

[0003] Chinese Patent Publication No. CN214718233U discloses a screening device for rice noodle production and processing, including a screening chamber, a sieve plate, and a feeding chamber. The sieve plate is installed at the bottom of the screening chamber, and a distribution plate is installed on one side of the movable rod and the sliding rod. This utility model, by setting up a screening mechanism, starts a third servo motor, which drives the drive gear to rotate. Since the drive gear is threadedly connected to the movable rod, it drives the movable rod to move. At this time, the sliding rod also moves, which in turn drives the distribution plate to move to the right to feed the rice noodles. Then, the first servo motor is started, which drives the eccentric wheel to rotate, thus driving the sieve plate to move up and down to screen the rice noodles. At this time, the second servo motor is started, which drives the stirring rod to stir the rice noodles, thereby accelerating the screening efficiency of the rice noodles and greatly improving the practicality of the device in use.

[0004] The aforementioned patent documents still have the following defects in practice:

[0005] During the screening process, rice flour clumps tend to accumulate on the sieve plate, and it is difficult to completely break up the clumps using only the stirring rod, resulting in insufficient screening and affecting the screening accuracy. Utility Model Content

[0006] The main objective of this invention is to provide a rice noodle screening device for rice noodle processing, which can effectively solve the problems mentioned above.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A rice noodle screening device for rice noodle processing includes four legs. The upper ends of the four legs are fixedly connected to a housing. A fixing frame is fixedly connected to the upper end of the housing. A motor is fixedly connected to the upper part of the fixing frame. A screening mechanism is fixedly connected to the output end of the motor. A feeding mechanism is fixedly connected to the upper part of the screening mechanism. A vibration mechanism is fixedly connected to the lower part of the screening mechanism.

[0009] Preferably, the screening mechanism includes a fixed rod, the upper end of which is fixedly connected to the motor output end, a plurality of crushing rods are fixedly connected to the middle part of the fixed rod, and three scrapers are fixedly connected to the lower part of the fixed rod.

[0010] Preferably, the screening mechanism further includes a sieve plate, the outer surface of which is fixedly connected to the middle of the inner cavity of the outer shell.

[0011] Preferably, the vibration mechanism includes a second sieve plate, the outer surface of which is slidably connected to the lower part of the inner cavity of the outer shell, two springs are fixedly connected to the lower end of the second sieve plate, and a fixing plate is fixedly connected to the lower end of each of the two springs. The two fixing plates are respectively fixedly connected to both sides of the inner cavity of the outer shell, and two fixing rods are fixedly connected to the lower end of the second sieve plate.

[0012] Preferably, the vibration mechanism further includes two fixing blocks, which are jointly fixedly connected to the lower part of the outer surface of the fixing rod.

[0013] Preferably, the feeding mechanism includes a pulley one, the inner surface of the pulley one being fixedly connected to the upper part of a fixed rod one, the outer surface of the pulley one being covered with a transmission belt, a pulley two being wound around the end of the transmission belt away from the pulley one, a connecting rod being fixedly connected to the inner surface of the pulley two, a spiral blade being fixedly connected to the outer surface of the connecting rod, a housing two being fixedly connected to the upper part of the outer surface of the connecting rod, a feeding hopper being fixedly connected to the upper part of the housing two, a support rod being fixedly connected to the lower end of the feeding hopper, and the lower end of the support rod being fixedly connected to the upper end of the housing one.

[0014] Preferably, the inner surface of the feed hopper communicates with the inner cavity of the outer shell.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this embodiment, a screening mechanism is set up. Multiple crushing rods rotate with the fixed rod one, which can fully crush the rice noodle clumps entering the device. This solves the problem of rice noodle clumps accumulating and being difficult to pass through the sieve plate in traditional screening devices. During the rotation, the scraper crushes and disperses the rice noodles on the sieve plate two, further avoiding rice noodle clumps and ensuring more thorough screening. Through the two-stage screening structure of sieve plate one and sieve plate two, rice noodles can be coarsely and finely graded to meet different processing needs. The fixed setting of sieve plate one achieves preliminary screening, while sieve plate two, in conjunction with the vibration mechanism, achieves dynamic fine screening. The combination of the two-stage screening greatly improves the uniformity of the rice noodles.

[0017] 2. In this embodiment, a feeding mechanism is set up to drive the spiral blades to rotate through the belt pulley drive, so as to realize the quantitative conveying of rice noodles. The feeding amount can be controlled according to the screening rhythm, avoiding the problem of screen plate accumulation and insufficient screening caused by excessive feeding in traditional devices, and ensuring a stable and orderly screening process.

[0025] 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.

[0026] Example 1, as Figure 1 , Figure 2 and Figure 3 As shown, a rice noodle screening device for rice noodle processing includes four support legs 1. The upper ends of the four support legs 1 are all fixedly connected to a housing 2. The upper end of the housing 2 is fixedly connected to a fixing frame 3. The upper part of the fixing frame 3 is fixedly connected to a motor 4. The output end of the motor 4 is fixedly connected to a screening mechanism 6. The upper part of the screening mechanism 6 is fixedly connected to a feeding mechanism 5. The lower part of the screening mechanism 6 is fixedly connected to a vibration mechanism 7.

[0027] In this embodiment, rice noodles are placed into the feeding mechanism 5, and the motor 4 is started. The motor 4 drives the feeding mechanism 5 and the screening mechanism 6 to operate. The operation of the screening mechanism 6 drives the vibration mechanism 7 to operate. The rice noodles in the feeding mechanism 5 enter the outer shell 2 and are screened layer by layer under the action of the screening mechanism 6. After being collected at the lower end of the outer shell 2, they fall out of the outer shell 2.

[0028] To select rice noodles, please refer to... Figure 4 The screening mechanism 6 includes a fixed rod 61, the upper end of which is fixedly connected to the output end of the motor 4, a number of crushing rods 62 are fixedly connected to the middle part of the fixed rod 61, and three scrapers 63 are fixedly connected to the lower part of the fixed rod 61. The screening mechanism 6 also includes a sieve plate 64, the outer surface of which is fixedly connected to the middle part of the inner cavity of the outer shell 2.

[0029] During implementation, motor 4 is started, which drives fixed rod 61 to rotate. Fixed rod 61 drives several crushing rods 62 and three scrapers 63 to rotate. Several crushing rods 62 perform initial crushing on the falling rice noodle clumps to improve screening efficiency. The qualified rice noodles fall onto the upper end of sieve plate 71 through sieve plate 64. The scrapers 63 crush the rice noodles on the upper end of sieve plate 71, causing the rice noodles to disperse and fall through sieve plate 71.

[0030] For further details, please refer to [link / reference]. Figure 5 The vibration mechanism 7 includes a second sieve plate 71, the outer surface of which is slidably connected to the lower part of the inner cavity of the outer shell 2. Two springs 74 are fixedly connected to the lower end of the second sieve plate 71, and a fixing plate 75 is fixedly connected to the lower end of each spring 74. The two fixing plates 75 are fixedly connected to both sides of the inner cavity of the outer shell 2 respectively. Two fixing rods 72 are fixedly connected to the lower end of the second sieve plate 71. The vibration mechanism 7 also includes two fixing blocks 73, which are fixedly connected to the lower part of the outer surface of the fixing rod 61.

[0031] During implementation, the rotation of the first fixed rod 61 drives the rotation of the fixed block 73. When the fixed block 73 rotates, it pushes the second fixed rod 72 upward. The second sieve plate 71 moves upward under the action of the second fixed rod 72, and the spring 74 is stretched. After the fixed block 73 leaves the second fixed rod 72, the spring 74 drives the second sieve plate 71 to reset, causing the second sieve plate 71 to vibrate and accelerate the screening of rice noodles.

[0032] Example 2: To control the feeding speed, refer to... Figure 6The feeding mechanism 5 includes a pulley 51, the inner surface of which is fixedly connected to the upper part of a fixed rod 61. The outer surface of the pulley 51 is covered with a transmission belt 52. A pulley 53 is wound around the end of the transmission belt 52 away from the pulley 51. A connecting rod 54 is fixedly connected to the inner surface of the pulley 53. A spiral blade 55 is fixedly connected to the outer surface of the connecting rod 54. A housing 56 is fixedly connected to the upper part of the outer surface of the connecting rod 54. A feeding hopper 57 is fixedly connected to the upper part of the housing 56. A support rod 58 is fixedly connected to the lower end of the feeding hopper 57. The lower end of the support rod 58 is fixedly connected to the upper end of the housing 2. The inner surface of the feeding hopper 57 communicates with the inner cavity of the housing 56.

[0033] During implementation, rice noodles are placed into the feed hopper 57, and the motor 4 is started. The motor 4 drives the fixed rod 61 to rotate, which in turn drives the pulley 51 to rotate. The pulley 51 drives the pulley 53 to rotate via the transmission belt 52. The pulley 53 drives the connecting rod 54 to rotate, which in turn drives the spiral blade 55 to rotate. The spiral blade 55 moves the rice noodles downward, thereby controlling the feeding speed and preventing the rice noodles from accumulating on the sieve plate 64 and sieve plate 71, which would affect the screening effect.

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.
