DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1: A multi-stage screening machine for natto protein processing, see Figure 1-Figure 5 As shown, it includes a support frame 1, a screening box 101, a feed hopper 2, a grading screening component and a discharge hopper 14. The screening box 101 is installed on the support frame 1 by bolt connection. The feed hopper 2 is installed on the top of the screening box 101 by welding. The discharge hopper 14 is installed on the bottom of the screening box 101 by welding. The screening box 101 is provided with a grading screening component for screening natto protein. It also includes a support block 3, a feed roller 4 and a servo motor 5. A feed roller 4 for intermittently feeding natto protein raw materials is rotatably provided in the feed hopper 2. The feed roller 4 is provided with multiple blades and partitions. The feed roller 4 penetrates to the outside of the feed hopper 2. A support block 3 is installed on the side of the feed hopper 2 by bolt connection. A servo motor 5 is installed on the support block 3 by bolt connection. The output shaft of the servo motor 5 is fixedly connected to the feed by a coupling.

[0029] See also Figure 2-Figure 5As shown, the grading screening assembly includes a first screen 6 and a second screen 601 slidably arranged in a screening box 101, the first screen 6 and the second screen 601 can be slid and pulled out from the screening box 101 laterally, the first screen 6 is located above the second screen 601, and the aperture of the second screen 601 is smaller than the aperture of the first screen 6, so as to facilitate the grading and screening of natto protein, and the screening box 101 is rotatably provided with two upper and lower rotating rods 10, the two rotating rods 10 are respectively located below the first screen 6 and the second screen 601, and five rotating rods 10 are fixedly connected to the rotating rods 10 by welding. A cam 11 is provided for striking the first screen 6 or the second screen 601, and the cam 11 can contact the first screen 6 or the second screen 601, and the two rotating rods 10 penetrate to the outside of the screening box 101, and the two rotating rods 10 are fixedly connected with a conveying wheel 12 by a key connection, and a conveying belt 13 is commonly provided on the two conveying wheels 12, and a supporting shell 8 is installed on the side of the screening box 101 by a bolt connection, and a driving motor 9 is installed in the supporting shell 8 by a bolt connection, and the output shaft of the driving motor 9 is fixedly connected to a rotating rod 10 by a coupling.

[0030] When it is necessary to screen the natto protein, the natto protein raw material is poured into the feed hopper 2, and the raw material falls on the discharge roller 4. Then, the servo motor 5 is started to drive the discharge roller 4 to rotate, so that the natto protein raw material is intermittently discharged into the screening box 101 without causing blockage and jamming. After the raw material enters the screening box 101, the driving motor 9 drives the rotating rod 10 to rotate, and drives another rotating rod 10 to rotate synchronously under the transmission of the two conveying wheels 12 and the conveyor belt 13. The rotating rod 10 drives the cam 11 to rotate and intermittently contact the first screen 6 and the second screen 601, so that the cam 11 hits the first screen 6 and the second screen 601. After the raw material on the first screen 6 is screened, it falls on the second screen 601 for screening. Since the leakage hole of the second screen 601 is smaller than that of the first screen 6, the effect of graded screening is achieved, so that the quality of the natto protein is higher. By sliding and pulling the first screen 6 and the second screen 601 out of the screening box 101, the residual impurities and larger protein particles can be cleaned.

[0031] Example 2: Based on Example 1, refer to Figure 3-Figure 5 As shown, it also includes two rolling rollers 15 for crushing natto protein raw materials, which are rotatably arranged in the screening box 101. The two rolling rollers 15 penetrate to the outside of the screening box 101. One side of one rolling roller 15 is fixedly connected to the unloading roller 4 with a transmission wheel 16 by a key connection. The two transmission wheels 16 are jointly provided with a transmission belt 17. The other side of the rolling roller 15 is fixedly connected to a first gear 18 by a key connection. The other rolling roller 15 is fixedly connected to a second gear 19 by a key connection. The first gear 18 and the second gear 19 are meshed with each other.

[0032] When the natto protein raw material enters the screening box 101 from the feed hopper 2, the raw material will first fall on the two rolling rollers 15. At this time, the rolling rollers 15 rotate to discharge the material. The rolling rollers 15 drive a rolling roller 15 to rotate synchronously through the cooperation of the transmission wheel 16 and the transmission belt 17. The rolling roller 15 drives the first gear 18 and the second gear 19 to mesh and rotate, so that the two rolling rollers 15 rotate in opposite directions, so that the natto protein raw material on the two rolling rollers 15 is crushed and falls from the middle, so that the natto protein is crushed.

[0033] See also Figure 4 and Figure 6 As shown, it also includes a fixed plate 21 installed on both sides of the inside of the screening box 101 by bolt connection, and three limit rods 23 are fixedly connected to the fixed plate 21 by welding. A scraper 22 for scraping off the residual natto protein on the rolling roller 15 is commonly provided on the three limit rods 23 in a transverse sliding manner, and a telescopic spring 24 is wound around the limit rod 23, and the telescopic spring 24 pushes the scraper 22 to contact the rolling roller 15 on the same side.

[0034] After the rolling roller 15 has rolled the natto protein, some natto protein may remain on the rolling roller 15. As the rolling roller 15 rotates, the rolling roller 15 contacts the scraper 22, and the natto protein attached to the rolling roller 15 is scraped off by the scraper 22. When the scraper 22 encounters a large resistance, the scraper 22 will slide along the limit rod 23 to the side close to the fixed plate 21. At this time, the telescopic spring 24 is compressed and deformed by the force. When the scraper 22 loses resistance, the telescopic spring 24 pushes the scraper 22 to slide and reset, and continues to hang material on the surface of the rolling roller 15.

[0035] See also Figure 7 As shown, it also includes two fixed blocks 25 installed on both sides of the outside of the discharge hopper 14 by bolt connection, and two guide rods 28 are horizontally slidably arranged on the two fixed blocks 25. The two guide rods 28 are fixedly connected with a clamping plate 26 for clamping the packaging bag by welding, and a threaded rod 27 is rotatably arranged on the clamping plate 26, and the threaded rod 27 is threadedly connected to the fixed block 25.

[0036] When the sieved natto protein needs to be packaged, the packaging bag is put on the discharge hopper 14, and the threaded rods 27 on both sides are rotated to make the clamping plates 26 on both sides slide along the side close to each other of the fixing block 25 through the guide rod 28, and the packaging bag is clamped and fixed on the discharge hopper 14 by the two clamping plates 26, without using a rope to fix the packaging bag; by rotating the threaded rod 27 in the opposite direction, the two clamping plates 26 can loosen the packaging bag, and the packaging bag can be removed from the discharge hopper 14 and sealed.

[0037] See also Figure 1 and Figure 4As shown, two top frames 7 are installed in the screening box 101, and the two top frames 7 are respectively located directly below the first screen 6 and the second screen 601; transparent glass 2 is embedded on both sides of the screening box 101; a protective shell 29 is installed on the side of the screening box 101, and the first gear 18 and the second gear 19 are located in the protective shell 29.

[0038] When natto protein blocks the leakage holes of the first sieve 6 and the second sieve 601, as the second sieve 601 of the first sieve 6 shakes, the top frame 7 can poke the blocked leakage holes to avoid blockage; the screening of natto protein in the screening box 101 can be easily observed through the transparent glass 20; the protective shell 29 can protect the first gear 18 and the second gear 19 to prevent foreign objects from falling between the first gear 18 and the second gear 19 and causing jamming.
