Description

Technical Field

[0001] The utility model relates to the technical field of bran beating machine equipment, in particular to a bran beating machine for flour production. Background Art

[0002] According to the patent document with the publication number CN 220387059 U, the driving source drives the rotating shaft and the mounting bracket on the outside thereof to rotate through the belt, and the rotating mounting bracket drives the beating plate to rotate in the screen cylinder. At the same time, the beating plates of different thicknesses can be replaced to beat the bran and flour in the screen cylinder. In addition, the bolts connecting the beating plate and the mounting bracket are loosened, and the through groove on the beating plate is allowed to slide on the bolts to adjust the distance from the beating plate to the inner wall of the screen cylinder.

[0003] The patent document discloses that when the beating plate is used for beating, the bolts fixing the mounting bracket and the beating plate may become loose due to vibration. If the bolts become loose, the beating plate may move outward along its through groove, and then the beating plate may collide with the sieve drum, thereby causing damage to the entire sieve drum. At the same time, when the beating plate is beating the bran and flour, the undifferentiated bran may get stuck in the sieve holes of the sieve drum. If bran is stuck in the sieve holes, some of the flour may block the sieve holes where the bran is stuck. When too many sieve holes are blocked, the screening efficiency of the entire sieve drum will be affected, and some unscreened flour may be mixed in the delivered bran, thereby causing waste of flour.

[0030] The present utility model will be further described below with reference to the accompanying drawings:

[0031] As Figures 1 - 8 shown, a bran-beating machine for flour production includes a screening mechanism 1 for separating bran and flour. A bracket 4 for supporting the screening mechanism 1 is arranged outside the screening mechanism 1. A feed hopper 5 is fixed at one end of the screening mechanism 1. It further includes a bran-beating mechanism 2 and an anti-blocking mechanism 3 for preventing the bran from blocking the screening mechanism 1 after bran-beating.

[0032] In this embodiment: The screening mechanism 1 includes a separation cylinder 11. A screening cylinder 12 for separating bran and flour is arranged inside the separation cylinder 11. Two toothed rings 14 are fixed outside the screening cylinder 12. A transmission rod 15 is arranged above the screening cylinder 12. A gear meshing with the toothed ring 14 is fixed outside the transmission rod 15. A screening motor 13 is fixedly arranged at the input end of the transmission rod 15. Both ends of the transmission rod 15 are rotatably connected to both ends of the separation cylinder 11 respectively. A conical opening for facilitating the discharge of flour is arranged below the separation cylinder 11. L-shaped rings are fixed at both ends of the screening cylinder 12. And bosses for supporting the L-shaped rings are arranged inside the separation cylinder 11 at the positions of the L-shaped rings. The rotation part of the screening motor 13 drives the transmission rod 15 to rotate. Through the meshing of the two gears on the transmission rod 15 with the toothed ring 14, and at the same time through the cooperation of the L-shaped rings at the ends of the screening cylinder 12 and the bosses, the screening cylinder 12 is enabled to rotate inside the separation cylinder 11.

[0033] In this embodiment: The bran-beating mechanism 2 includes a rotating shaft 22 which is located at the central position inside the screening mechanism 1. Three fixed plates 23 are circumferentially fixed on the outer side of the rotating shaft 22. At the end of the fixed plate 23 far from the rotating shaft 22, there is a corresponding bran-beating plate 24. And at the end of each fixed plate 23, an adjusting screw 25 is connected by thread. The end of the adjusting screw 25 is threadedly connected to the adjusting screw 25. Below the screening mechanism 1, there is a bran-beating motor 21 for driving the rotation of the rotating shaft 22. The rotating part of the bran-beating motor 21 is in belt transmission with one end of the rotating shaft 22. By using the rotating part of the bran-beating motor 21 to drive the rotating shaft 22 to rotate at the central position inside the separation cylinder 11, the rotation of the rotating shaft 22 drives the three fixed plates 23 and the bran-beating plates 24 to rotate synchronously. Then, the rotating bran-beating plates 24 beat the bran and flour in the screening cylinder 12, so as to accelerate the separation of the bran from the flour. At the same time, by rotating the adjusting screw 25 at the end of the fixed plate 23, the distance between the bran-beating plate 24 and the inner wall of the separation cylinder 11 is adjusted.

[0034] In this embodiment: The anti-blocking mechanism 3 includes a concave-convex plate 31 which is fixed at the end of the rotating shaft 22 far from the bran-beating motor 21. There are brush-sweeping frames 33 on the front and back sides of the concave-convex plate 31. One end of the brush-sweeping frame 33 is provided with a return spring 34. The other end of the brush-sweeping frame 33 is rotatably connected to a guide rod 32. The end of the guide rod 32 far from the brush-sweeping frame 33 is attached to the end of the concave-convex plate 31. There are multiple protrusions at the end of the concave-convex plate 31, and the multiple protrusions are annularly distributed. At the middle position of the brush-sweeping frame 33, there are hard bristles for reciprocally brushing the outer side of the screening cylinder 12. And at one end of the brush-sweeping frame 33, there is a mounting plate for fixing the return spring 34. By driving the concave-convex plate 31 to rotate synchronously when the rotating shaft 22 rotates, then the protrusions at the end of the concave-convex plate 31 alternately push the two guide rods 32 through rotation. At the same time, under the action of the return spring 34, the brush-sweeping frame 33 makes a reciprocating movement. Then, the hard bristles on the brush-sweeping frame 33 are used to clean the sieve holes on the screening cylinder 12 to prevent the bran from blocking in the sieve holes of the screening cylinder 12.

[0035] Working principle: When in use, the material to be bran-beaten is introduced into the feed hopper 5, and the material is introduced into one side position inside the screening cylinder 12 through the feed hopper 5. At this time, the rotating part of the screening motor 13 drives the transmission rod 15 to rotate. The two gears on the transmission rod 15 are engaged with the toothed ring 14. At the same time, through the cooperation of the L-shaped ring at the end of the screening cylinder 12 and the convex platform, the screening cylinder 12 rotates inside the separation cylinder 11. Then, the bran and flour in the whole material roll and screen inside the screening cylinder 12, and at the same time, the bran and flour move towards the other end of the screening cylinder 12 when rolling;

[0036] During the screening and rolling process of bran and flour, the rotating part of the bran-beating motor 21 drives the rotating shaft 22 to rotate at the central position inside the separation cylinder 11 through belt transmission. The rotation of the rotating shaft 22 drives the three groups of fixing plates 23 and bran-beating plates 24 to rotate synchronously. Then, the rotating bran-beating plates 24 beat the bran and flour in the screening cylinder 12, thereby accelerating the separation of bran from flour. In addition, the distance between the bran-beating plate 24 and the inner wall of the separation cylinder 11 is adjusted by rotating the adjusting screw 25 at the end of the fixing plate 23.

[0037] During the entire bran-beating process, the flour falls out from the sieve holes of the screening cylinder 12, while the bran remains inside the screening cylinder 12 as it rotates. After rolling for a certain period of time, the bran is sent out from the other end of the screening cylinder 12.

[0038] In addition, during the bran-beating process, the rotation of the concave-convex plate 31 driven by the rotating shaft 22 causes the protrusions at its end to alternately push against the two guide rods 32. At the same time, under the action of the return spring 34, the brush-sweeping frame 33 moves reciprocally. Then, the hard bristles on the brush-sweeping frame 33 clean the sieve holes on the screening cylinder 12, thereby quickly removing the bran stuck in the sieve holes of the screening cylinder 12.

[0039] The above shows and describes the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
