The chute is installed in conjunction with the fine material discharge port to accurately control the size of the meat powder particles, improve the screening efficiency, help avoid the over-screening or under-screening of the meat powder, and improve the quality and reliability of the screening.

[0010] Furthermore, it also includes a single-chip microcomputer, which is arranged on the front side of the shell, and the input end of the single-chip microcomputer is electrically connected to an external power supply to facilitate the regulation of the operation of various electrical appliances.

[0011] Furthermore, a coarse material discharge port is provided on the left side of the shell, and the coarse material discharge port is installed in cooperation with a small-diameter filter screen to facilitate graded discharge.

[0012] Furthermore, it also includes a sliding column 1, which is fixedly connected to the upper surface of the large-diameter filter screen, and the top of the sliding column 1 is slidably connected to the sliding hole of the top wall of the slide groove 1. A spring 1 is fixedly connected between the top wall of the slide groove 1 and the upper surface of the adjacent large-diameter filter screen, and the spring 1 is sleeved on the outer surface of the sliding column 1 to achieve a large-scale up and down reciprocating motion.

[0013] Furthermore, it also includes sliding columns 2, which are fixedly connected to the upper surface of the small-diameter filter screen, and the top of the sliding columns 2 are slidably connected to the sliding holes in the top wall of the second slide groove. A spring 2 is fixedly connected between the top wall of the second slide groove and the upper surface of the adjacent small-diameter filter screen, and the spring 2 is sleeved on the outer surface of the sliding column 2.

The output shaft of the motor drives the rotating shaft to rotate, and the rotating shaft drives the eccentric protrusion to rotate. When the protrusion rotates, the central axis of the protrusion does not coincide with the central axis of the rotating shaft, causing the protrusion to rotate around the central axis of the rotating shaft. As the protrusion rotates, the mounting block also rotates around the central axis of the rotating shaft, thereby driving the support rod to rotate in the rotating groove through the pin shaft for avoidance, thereby driving the large-diameter filter screen to reciprocate up and down during continuous rotation. Then, when the large-diameter filter screen reciprocates up and down, the spring 1 is continuously compressed and then bounces up, driving the sliding column 1 to slide in the sliding hole, realizing a large-scale up and down reciprocating motion, so that the screening area can be fully utilized, and the meat powder can do more jumping and tumbling movements on the screen, which is beneficial to improving the screening accuracy and sorting effect.

[0018] 2. The protrusion contacts the upper surface of the small-diameter filter when rotating. When the end with a larger diameter of the protrusion contacts the upper surface of the small-diameter filter, the small-diameter filter will be pressed downward. At the same time, spring 2 will be compressed, driving slide column 2 to slide in the slide hole to achieve the downward pressing action. When the end with a smaller diameter of the protrusion contacts the upper surface of the small-diameter filter, spring 2 will release the stored energy, causing the small-diameter filter to bounce upward, and then continue to reciprocate up and down to achieve the purpose of screening. However, through the change of the diameter of the protrusion and the action of spring 2, the up and down movement of the small-diameter filter can be controlled to achieve the screening and separation of meat powder. Through small-amplitude vibration, the residence time of meat powder on the screening net can be more accurately controlled, which helps to avoid the over-screening or under-screening of meat powder and improve the quality and reliability of screening.

The slide column 2 The top of 12 is slidably connected with the sliding hole of the top wall of the second slide groove 11, and the top wall of the second slide groove 11 and the upper surface of the adjacent small-diameter filter screen 10 are fixedly connected with the second spring 13, and the second spring 13 is sleeved on the outer surface of the second slide column 12. The bottom end of the right side of the shell 1 is provided with a fine material discharge port 7, and also includes a single-chip microcomputer 8, which is arranged on the front side of the shell 1, and the input end of the single-chip microcomputer 8 is electrically connected to an external power supply. The left side of the shell 1 is provided with a coarse material discharge port 14, and the coarse material discharge port 14 is installed in conjunction with the small-diameter filter screen 10. After the screening is completed, the meat powder moves toward the small-diameter filter screen 10 at an inclined angle until it is sent to the coarse material discharge port 14;

[0027] Driving mechanism 6: It is arranged in the middle of the right side of the shell 1, and the left end of the driving mechanism 6 extends to the inside of the shell 1. The driving mechanism 6 is respectively installed with the large-diameter filter 3 and the small-diameter filter 10. The driving mechanism 6 includes a protrusion 62, a rotation groove 63, a mounting block 64, a support rod 65 and a rotating shaft 66. The rotating shaft 66 is rotatably connected to the middle of the right side of the shell 1. The left end of the rotating shaft 66 is fixedly connected with the protrusion 62. The central axis of the protrusion 62 does not coincide with the central axis of the rotating shaft 66. The outer surface of the protrusion 62 is installed with the upper surface of the small-diameter filter 10. The left side of the protrusion 62 is fixedly connected with the mounting block 64. The top of the mounting block 64 is provided with a rotation groove 63. The inside of the rotation groove 63 is rotatably connected with the support rod 65 through a pin. The top of the support rod 65 The driving mechanism 6 is fixedly connected to the lower surface of the large-diameter filter screen 3. The driving mechanism 6 also includes a motor 61. The motor 61 is installed in the middle of the right side surface of the housing 1 by bolts. The left end of the output end of the motor 61 is fixedly connected to the right end of the rotating shaft 66. The input end of the motor 61 is electrically connected to the output end of the single-chip computer 8. The meat powder is sprinkled on the large-diameter filter screen 3 in sequence, and then the operation of the motor 61 is regulated by the single-chip computer 8. The output shaft of the motor 61 drives the rotating shaft 66 to rotate, and the rotating shaft 66 drives the eccentric protrusion 62 to rotate. When the protrusion 62 rotates, the central axis of the protrusion 62 does not coincide with the central axis of the rotating shaft 66, causing the protrusion 62 to rotate around the central axis of the rotating shaft 66. As the protrusion 62 rotates, the mounting block 64 also rotates around the central axis of the rotating shaft 66. The wire rotates, thereby driving the support rod 65 to rotate in the rotating groove 63 through the pin shaft to avoid, thereby driving the large-diameter filter screen 3 to reciprocate up and down during continuous rotation, and then the large-diameter filter screen 3 will continuously compress the spring 5 and then bounce up during the up and down reciprocating motion, driving the slide post 2 to slide in the slide hole, realizing a large-scale up and down reciprocating motion, so that the screening area can be fully utilized, and the meat powder can do more jumping and rolling movements on the screen, which is beneficial to improving the screening accuracy and sorting effect. The meat powder after screening falls onto the upper surface of the small-diameter filter screen 10, and the meat powder with a larger diameter stays on the upper surface of the large-diameter filter screen 3. At the same time, the protrusion 62 contacts the upper surface of the small-diameter filter screen 10 during rotation. When the end with a larger diameter of the protrusion 62 contacts the small-diameter filter screen 10, the protrusion 62 is in contact with the upper surface of the small-diameter filter screen 10. When the upper surface of the mesh 10 contacts, the small-diameter filter 10 will be pressed downward, and the spring 2 13 will be compressed, driving the slide column 2 12 to slide in the slide hole to achieve the downward pressing action. When the end of the projection 62 with a smaller diameter contacts the upper surface of the small-diameter filter 10, the spring 2 13 will release the stored energy, causing the small-diameter filter 10 to bounce upward, and then continue to reciprocate up and down to achieve the purpose of screening. However, through the change in the diameter of the projection 62 and the action of the spring 2 13, the up and down movement of the small-diameter filter 10 can be controlled to achieve the screening and separation of meat powder. The residence time of the meat powder on the screening net can be more accurately controlled through small-amplitude vibration, which helps to avoid the situation where the meat powder is over-screened or not screened, and improves the quality and reliability of screening.

[0028] The chute 9 is provided on the bottom wall of the outer shell 1 and is installed in cooperation with the fine material outlet 7. The meat powder with a smaller diameter screened out falls into the chute 9 through the sieve holes of the small-diameter filter 10, and then the meat powder flows out to the outside through the fine material outlet 7 due to the characteristics of the chute 9.

[0029] The working principle of the multi-stage screening device for meat powder production provided by the utility model is as follows: the meat powder is sprinkled on the large-diameter filter screen 3 in sequence, and then the motor 61 is controlled to operate by the single-chip microcomputer 8, the output shaft of the motor 61 drives the rotating shaft 66 to rotate, and the rotating shaft 66 drives the eccentric protrusion 62 to rotate, when the protrusion 62 rotates, because the central axis of the protrusion 62 does not coincide with the central axis of the rotating shaft 66, the protrusion 62 rotates around the central axis of the rotating shaft 66, and as the protrusion 62 rotates, the mounting block 64 also rotates around the central axis of the rotating shaft 66, thereby driving the protrusion 62 to rotate. The movable support rod 65 is rotated in the rotating groove 63 through the pin shaft to avoid, thereby driving the large-diameter filter 3 to reciprocate up and down during continuous rotation, and then the large-diameter filter 3 will continuously compress the spring 15 and then bounce up during the up and down reciprocating motion, driving the slide post 12 to slide in the slide hole, realizing a large-scale up and down reciprocating motion, so that the screening area can be fully utilized, and the meat powder can do more jumping and rolling movements on the screen, which is beneficial to improving the screening accuracy and sorting effect. After the screening is completed, the meat powder falls onto the upper surface of the small-diameter filter 10, and the meat powder with a larger diameter stays on the upper surface of the large-diameter filter 3. At the same time, the protrusion 62 contacts the upper surface of the small-diameter filter 10 during rotation. When the end of the protrusion 62 with a larger diameter contacts the upper surface of the small-diameter filter 10, the small-diameter filter 10 will be pressed downward, and the spring 13 will be compressed, driving the slide post 12 to slide in the slide hole to achieve the downward pressing action. When the end of the protrusion 62 with a smaller diameter contacts the upper surface of the small-diameter filter 10, the spring 13 will release the stored energy, causing the small-diameter filter 10 to bounce upward, and then continue to reciprocate up and down to achieve the purpose of screening. However, the diameter of the protrusion 62 is different from that of the The change and the action of spring 2 13 can control the up and down movement of the small-diameter filter 10 to achieve screening and separation of meat powder. Through small-amplitude vibration, the residence time of meat powder on the screening net can be more accurately controlled, which helps to avoid the over-screening or un-screening of meat powder and improve the quality and reliability of screening. After screening, the meat powder moves at an inclined angle toward the small-diameter filter 10 until it is sent to the coarse material discharge port 14. The meat powder with a smaller diameter screened out falls into the chute 9 through the sieve holes of the small-diameter filter 10, and then flows out to the outside through the fine material discharge port 7 through the characteristics of the chute 9.

The single chip microcomputer 8 controls the operation of the motor 61 using the method commonly used in the prior art.
