DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 The utility model provides a new technical solution: a grinding device for protein powder production, comprising a screening box 1, a grinding cylinder 17 is arranged on the screening box 1, a sieve plate 2 is rotatably connected in the screening box 1, and a screening assembly is arranged on the screening box 1, and the screening assembly is used to screen the protein powder ground by the grinding cylinder 17;

[0026] The screening box 1 is provided with two screening anti-blocking mechanisms, which are used to prevent the screen plate 2 from being blocked too much during use;

[0027] The screening anti-blocking mechanism includes a slide rail 4, a slide groove 3 is provided on one side of the screen plate 2, the slide groove 3 is inclined, the slide rail 4 is slidably connected in the slide groove 3, and a tension spring fixing block 7 is integrally formed on the outer surface of the screen plate 2;

[0028] The lower end of the slide rail 4 is fixedly connected with a struck block 5, and the struck block 5 is fixedly connected with an impact column 6, which is used to impact the tension spring fixing block 7 to generate impact shock force, and a tension spring 8 is fixedly connected between the struck block 5 and the tension spring fixing block 7.

[0029] Furthermore, the outer surface of the slide rail 4 is fixedly connected to a fixed slide column 9, the inner wall of the screening box 1 is fixedly connected to an inclined plate 10, the inclined plate 10 is adapted to the fixed slide column 9, and a discharge hopper 16 is fixedly connected inside the screening box 1. The discharge hopper 16 is used to receive the protein powder after screening, and the discharge hopper 16 extends out of the outer surface of the screening box 1.

[0030] Furthermore, the screening assembly includes a screening plate 2, which is rotatably connected between the inner walls of the screening box 1, and arc-shaped fixing plates 11 are fixedly connected to both sides of the lower surface of the screening box 1.

[0031] Furthermore, one end of the two arc-shaped fixing plates 11 away from the sieve plate 2 extends out of the outer surface of the screening box 1 , and a movable column 12 is fixedly connected between the ends of the two arc-shaped fixing plates 11 away from the sieve plate 2 .

[0032] Furthermore, a large tension spring 18 is fixedly connected between the movable column 12 and the outer surface of the screening box 1 , the motor 13 is fixedly connected by bolts, and the outer surface of the output shaft of the motor 13 is fixedly sleeved with a hexagonal shaft 14 .

[0033] Furthermore, an eccentric sheave 15 is slidingly sleeved on the outer surface of the hexagonal shaft 14 , and a circular groove matching the outer surface of the movable column 12 is formed on the outer surface of the eccentric sheave 15 .

[0034] Furthermore, when in use, by starting the motor 13, the output shaft of the motor 13 drives the eccentric groove wheel 15 on it to rotate through the hexagonal shaft 14 thereon. When the eccentric groove wheel 15 rotates, the movable column 12 can move away from the screening box 1, and at the same time, the large tension spring 18 produces elastic tensile deformation, thereby driving the two arc-shaped fixed plates 11 and the sieve plate 2 thereon to swing slightly, so as to screen the protein powder falling from the grinding cylinder 17, and when the sieve plate 2 makes a small reciprocating swing, it will contact the inclined plate 10 through the fixed sliding column 9.

The tension spring 8 itself is elastically restored quickly, driving the impacted block 5 and the impact column 6 to quickly impact on the tension spring fixed block 7, so that one impact can produce an upward impact shock force on the sieve plate 2, so that the protein powder blocked in the sieve plate 2 can be separated by the impact shock, which effectively reduces the blockage problem caused by uneven particle size during the screening process.

[0035] Furthermore, the screening anti-blocking mechanism can generate an impact shock force obliquely upward, so that the particles blocked in the sieve holes are vibrated and loosened, and then discharged smoothly. This vibration dredging method is both efficient and reliable, effectively reducing the retention and blockage of particles on the screen plate, and can significantly improve the dredging efficiency of the screen plate, thereby improving work efficiency.

[0036] Working principle: when in use, by starting the motor 13, the output shaft of the motor 13 drives the eccentric groove wheel 15 on it to rotate through the hexagonal shaft 14 thereon, and when the eccentric groove wheel 15 rotates, the movable column 12 can move in the direction away from the screening box 1, and at the same time, the large tension spring 18 produces elastic tensile deformation, thereby driving the two arc-shaped fixed plates 11 and the sieve plate 2 thereon to swing slightly, thereby screening the protein powder falling from the grinding cylinder 17, and when the sieve plate 2 makes a small reciprocating swing, it will contact the inclined plate 10 through the fixed slide column 9, and then drive the slide rail 4 to move in the axial direction of the slide groove 3, so that the tension spring 8 produces elastic tensile deformation until the fixed slide column 9 is separated from the inclined plate 10, and the tension spring 8 itself is elastically restored quickly, driving the impacted block 5 and the impact column 6 to quickly impact on the tension spring fixed block 7, so that one impact can produce an impact shock force obliquely upward on the sieve plate 2, so that the protein powder blocked in the sieve plate 2 can be separated by this impact shock.
