The rotating shaft 22 has a first rotating paddle 221 and a second rotating paddle 222. The first rotating paddle 221 is a propeller, and the second rotating paddle 222 is a square paddle.

Wherein the second pulley 21 is arranged above the turning rod 22. The second belt pulley 21 and the first belt pulley 11 are at the same height and are in transmission connection through a belt. Rotating shaft 22 is a cylindrical body divided into a first section 223 and a second section 224. The first section 223 is located below the liquid level in the sand reservoir 3 and the second section 224 is located above the liquid level.

The first rotating paddle 21 has three blades to drive the fluid to flow upward and downward. The second rotating paddle 222 has two blades that drive the fluid to flow laterally. Any blade of the first rotating paddle 211 and two blades of the second rotating paddle 222 are not on the same vertical plane, and the first rotating paddle 211 and the second rotating paddle 222 can fully stir the grinding fluid and keep a good suspension state.

Specifically, the sand storage container 3 is used for storing the grinding material in a stirring manner. The top surface of the sand storage container 3 is open, and a liquid outlet 31 is arranged below the side wall of the sand storage container. In the present embodiment, a hollow rectangular parallelepiped sand storage container 3 is exemplified. The top surface of this hollow cuboid is open, and drain port 31 is located the lower portion of the right side wall of the cuboid at a position adjacent to the bottom surface.

Specifically, the connection pipe 4 is a rubber pipe for guiding the abrasive in the sand storage container 3 to the grinding mechanism 6. The connecting pipe 4 is connected with a liquid outlet 31 below the sand storage container 3. The abrasive in the sand storage container 3 enters the connecting pipe 4 through the discharge port 31, and is guided into the grinding mechanism 6 through the connecting pipe 4.

Specifically, the flow restriction valve 5 is installed on the connection pipe 4. The constrictor valve 5 has a housing 51 and a hold-down mechanism 52.

The housing 51 has a through cavity 511 therein. One side of the cavity 511 is a first pressing surface 513. A through screw hole 512 is opened in the wall of the housing 51. The screw hole 512 is located adjacent to an end region through which the housing 51 penetrates, with the penetrating direction facing the first pressing surface 513. In the present embodiment, a rectangular parallelepiped case 51 will be described as an example. A rectangular parallelepiped cavity 511 is formed in the housing 51. The first pressing surface 513 is a flat surface. The connection pipe 4 passes through the cavity 51, and the surface thereof is in contact with the first pressing surface 513. Under the action of external force, the connecting tube 4 is deformed. When the external force is removed, the connection pipe 4 can restore the deformation.

The pressing mechanism 52 includes a screw 521 and a pressing block 522. The screw 521 passes through the screw hole 512, and has one end extending into the cavity 511, and the surface thereof is screwed with the inside of the screw hole 512.

The operation principle of the flow restriction valve 5 is that the polishing liquid flows toward the polishing mechanism 6 at the maximum flow rate when no squeezing is generated between the connection pipe 4, the first squeezing surface 513, and the second squeezing surface 523. When the screw 521 is screwed in the direction of the connection pipe 4, the pressing piece 522 gradually moves in the direction of the first pressing surface 513 and gradually presses the connection pipe 4. The connecting pipe 4 is deformed by pressure, and the fluid passage is narrowed, thereby performing a flow restriction function. When the connecting pipe 4 is deformed to completely block the flow passage, the supply of the liquid to the grinding mechanism 6 is stopped. When the screw 521 is unscrewed, the connection pipe 4 automatically returns to its original shape due to elasticity, and the polishing liquid is discharged.

In this embodiment, the automatic sand supply device of the optical glass sample grinding machine has the following working modes:

the screw 521 is screwed in the direction of the connection pipe 4 to deform the connection pipe 4 to completely block the fluid passage. The abrasive and water are added to the sand reservoir 3 and the motor 1 is started. The motor 1 drives the stirrer 2 to rotate at a speed of 150-200 rpm. During the rotation of the agitator 2, the first rotating paddle 211 drives the slurry to flow in a vertical convection manner, and the second rotating paddle 222 drives the fluid to flow in a lateral direction, so as to accelerate the dispersion of the slurry. Stirring and mixing for 30-60 min, slowly screwing out the screw 521, and determining the screwing-out amount according to the requirement. The connecting pipe 4 is slowly restored to the shape, and the grinding fluid passes through the connecting pipe 4 and is guided to the grinding mechanism 6 through the flow limiting valve 5. In the process of guiding the grinding fluid to the grinding mechanism 6, the stirrer 2 maintains a rotating working state, so that the grinding fluid can be automatically supplied according to the requirement, and the processing efficiency and the processing quality are improved.
