During the processing of ceramic materials, the materials need to be stirred. However, due to the different sizes of the materials, in order to improve the stirring effect, the materials need to be crushed to obtain materials of the same size. However, the existing ceramic material crushing and stirring devices usually have a large number of crushing and stirring dead corners, which makes some materials unable to be crushed and stirred, resulting in reduced stirring effect.

DETAILED DESCRIPTION

[0016] 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.

[0017] See also Figure 1-3 A material stirring device for ceramic processing includes a stirring box 1. A plurality of feeding funnels 2 are installed on the top shell wall of the stirring box 1. The specific number of the feeding funnels 2 is two. A motor 3 is installed in the stirring box 1. A stirring shaft 4 is installed at the bottom of the motor 3. A plurality of stirring blades 5 are installed on the surface of the stirring shaft 4. Starting the motor 3 to rotate the stirring shaft 4 will drive the material in the stirring box 1 to move through the stirring blades 5 to stir the material. It should be noted that the motor 3 is a stepping motor. When the motor 3 is started, after controlling the stirring shaft 4 to rotate in the forward direction for a period of time, it will control the stirring shaft 4 to rotate in the reverse direction, and the time and speed of the forward rotation and reverse rotation of the stirring shaft 4 are the same. When the motor 3 is started, it will repeatedly control the stirring shaft 4 to rotate in the forward and reverse directions.

[0018] Motor 2 6 is installed on the left and right side walls of the mixing box 1, and a rotating shaft 7 is installed on the motor 2 6. The rotating shaft 7 passes through the wall of the mixing box 1 and is located in the mixing box 1. A crushing blade 8 is installed on the surface of the rotating shaft 7, and the crushing blade 8 is located below the feeding funnel 2. Starting the motor 2 6 will drive the crushing blade 8 to rotate through the rotating shaft 7, and the material entering the mixing box 1 from the feeding funnel 2 will be crushed to reduce the volume of the material.

[0019] A plurality of sieve plates 9 are installed in the mixing box 1, and the specific number of the sieve plates 9 is two. The sieve plates 9 are located below the rotating shaft 7. The sieve plates 9 are composed of many small holes, which can screen the size of the material, so that the smaller material that meets the requirements passes through the sieve plate 9, and the larger material remains on the top of the sieve plate 9, so that it continues to be crushed by the crushing blade 8 until the size meets the requirements. A plurality of vertically downward electric push rods 17 are installed inside the mixing box 1. The specific number of the electric push rods 17 is two, and they are respectively located above the two sieve plates 9. A grinding block 18 is installed on the output end of the electric push rod 17. Starting the electric push rod 17 can control the grinding block 18 to move up and down, and the material located on the top of the sieve plate 9 that cannot be crushed by the crushing blade 8 is crushed and ground, thereby increasing the crushing speed, expanding the crushing range, and avoiding the accumulation of materials in the dead corner at the top of the sieve plate 9. An upwardly extending baffle 10 is installed on the top of the sieve plate 9, and the top of the baffle 10 is connected to the top inner wall of the mixing box 1. The baffle 10 can limit the splash range of the material when it is crushed to avoid the material from causing damage to other internal devices.

[0020] A gear 11 is sleeved on the surface of the stirring shaft 4, and an outer ring of a bearing 12 is installed in the left and right side walls of the stirring box 1. A threaded rod 13 is installed on the inner ring of the bearing 12, and a gear 2 14 is installed on the end of the threaded rod 13 away from the bearing 12. The gear 2 14 is in meshing state with the gear 1 11. When the stirring shaft 4 rotates, the threaded rod 13 is driven to rotate through the meshing of the gear 11 and the gear 2 14.

[0021] A slider 15 is threadedly connected to the threaded rod 13, and a push plate 16 is installed at the bottom of the slider 15. When the threaded rod 13 rotates, the slider 15 will move on the threaded rod 13 and drive the push plate 16 to move. When the push plate 16 moves, it will push the material in the mixing box 1 to move in the direction of the mixing blade 5. A limit block 23 is fixedly installed on the threaded rod 13. The limit block 23 will prevent the slider 15 from moving, thereby limiting the moving distance of the slider 15 on the threaded rod 13, so that the push plate 16 cannot always come into contact with the mixing blade 5 during the movement.

[0022] A discharge port 19 is provided on the bottom wall of the mixing box 1, and the discharge port 19 is located in the positive direction of the mixing shaft 4. A discharge valve 20 is installed in the discharge port 19. A collecting box 21 opening upward is installed at the bottom of the mixing box 1, and the collecting box 21 is located below the discharge port 19. When the discharge valve 20 is opened, the material inside the mixing box 1 will fall into the collecting box 21 through the discharge port 19. A plurality of supporting legs 22 are installed at the bottom of the mixing box 1, and the specific number of the supporting legs 22 is four.

[0023] During use, the user can put the material into the mixing box 1 through the feeding funnel 2, and at the same time start the motor 2 6 to rotate the crushing blade 8 to crush the material, and start the electric push rod 17 to make the grinding block 18 move up and down repeatedly to crush the material located on the top of the sieve plate 9. The crushed material will pass through the sieve plate 9 and fall on the bottom inner wall of the mixing box 1. Then start the motor 1 3 to rotate the stirring shaft 4 and the stirring blade 5 to stir the material. At the same time, the push plate 16 is moved by the rotation of the threaded rod 13 to continuously push the material toward the stirring blade 5 to increase the stirring speed.
