The No. 2 torsion spring is provided to drive the L-shaped rod back to its original position.

[0014] The present invention provides a glass powder grinding device for producing optical instrument glass. It has the following beneficial effects: (1) In the present invention, when the device is working normally, the No. 1 rotating shaft works normally, and the normal operation of the No. 1 rotating shaft drives the grinding head to rotate and grind the material on the grinding disc. The rotation of the No. 1 rotating shaft drives the cross bar to rotate, and the rotation of the cross bar will drive the inclined head plate to move. The movement of the inclined head plate will drive the opening and closing plate to rotate. The rotation of the opening and closing plate will drive the inclined rod to move. The movement of the inclined rod will drive the No. 2 gear shaft to rotate and drive the combing plate to rotate to clear the material inside the feed trough. When the opening and closing plate is intermittently opened and closed, the material will be intermittently fed into the main body so that the material will not rush into the main body in an instant and accumulate in the same place to affect the grinding. The rotation of the combing plate clears the material inside the feed trough so that the material will not block the feed trough and prevent the material from entering the main body for grinding.

[0015] (2) In the present invention, when the opening and closing plates intermittently feed the materials into the main body, the rotation of the opening and closing plates will drive the rotating rod to rotate, the rotation of the rotating rod will drive the hydraulic rod to move, the movement of the hydraulic rod will drive the hydraulic plate to move, the movement of the hydraulic plate will squeeze the liquid inside the water pump to be sprayed out through the water spray head, the rotation of the cross bar will drive the push rod to move, the movement of the push rod will drive the water spray head to rotate and evenly spray water on the inner wall of the main body, so that the dust generated during grinding will not adhere to the material and affect the grinding of the material, and the even water spraying can cool the inside of the main body so that the grinding will not be affected by the excessively high temperature inside the main body.

[0016] (3) In the present invention, when the scraper contacts the blocking block during rotation, it will be pushed to rotate backward by the reaction force. When the scraper rotates backward, it will squeeze the No. 1 torsion spring to accumulate force. The force of the No. 1 torsion spring will be released to push the scraper to rotate. When the scraper rotates, it will hit the L-shaped rod to rotate. The rotation of the L-shaped rod will push the inclined block to move. The movement of the inclined block will push the baffle plate to rotate. The rotation of the scraper will evenly spread the material on the surface of the grinding disc so that the material will not be accumulated in the same position all the time, resulting in uneven grinding of the material. The rotation of the baffle plate will scatter the material so that the material enters the main body in a more dispersed manner, further strengthening the grinding of the material and making it more evenly ground.
