[0002] A glass cup refers to a cup made of glass, usually made of raw material high borosilicate glass, fired at a high temperature of more than 600 degrees. It is a new type of environmentally friendly tea cup and is increasingly popular among people. During the production process of the glass cup, a grinding device is usually required to correct its bottom.

[0003] An existing device for polishing the bottom of a glass cup (Announcement No.: CN209665000U) has at least the following disadvantages: glasses of different sizes and diameters require the use of a corresponding clamp to fix them when polishing the bottom of the glass cup, which is very inconvenient. In addition, a large amount of glass powder will be generated during polishing, which may cause harm to surrounding workers if inhaled. Utility Model Content

[0013] 1. In the utility model, the crank can drive the worm to rotate, and the worm can control the worm wheel to drive the threaded rod to rotate. When the threaded rod rotates, the control block can be adjusted to move up and down. Rotating the threaded rod will move the control block downward. At this time, the control block will drive one end of the connecting rod to move downward, and the other end of the connecting rod will pull the movable block to move. The movable block will drive the splint to slide in the movable groove, so that the splint gathers towards the middle of the operating table to fix the glass, thereby achieving the effect of fixing glasses of different sizes.

[0014] 2. In the utility model, the tooth block connected to the outside of the protective cover passes through the side of the gear, and the tooth block will drive the gear to rotate to open the control valve. At this time, the water in the water tank is transported to the spray block through the delivery pipe and sprayed out to reduce dust. When the grinding is completed, the telescopic rod on the lifting device shrinks and resets, which will drive the tooth block on the side wall of the protective cover to move upward. At this time, the tooth block will drive the gear to reverse and close the control valve, thereby achieving automatic dust reduction during grinding, preventing glass powder from being inhaled by surrounding workers and causing harm to their bodies.

[0024] In this embodiment, a threaded rod 13 is provided inside the operating table 1, and the threaded rod 13 is movably installed in the middle position of the top of the operating table 1. A worm gear 14 is fixedly installed at the bottom of the threaded rod 13, and a worm 15 is provided on the right side of the worm gear 14. The worm gear 14 and the worm 15 are engaged with each other. The tail end of the worm 15 penetrates the side wall of the operating table 1 and is movably installed on the operating table 1. The tail end of the worm 15 is fixedly installed with a crank 12.

[0025] In this embodiment, a movable block 18 is fixedly installed at the bottom of the splint 3, and the movable block 18 is movably engaged in the movable groove 2. A connecting rod 20 is movably installed at the bottom of the movable block 18, and a control block 19 is provided on the threaded rod 13. The control block 19 is threadedly connected to the threaded rod 13, and the other end of the connecting rod 20 is movably connected to the side wall of the control block 19.

When the telescopic rod on the lifting device 4 falls, the tooth block 21 connected to the outside of the protective cover 5 will pass from the side of the gear 24. At this time, the tooth block 21 will drive the gear 24 to rotate to open the control valve 23. At this time, the water in the water tank 7 is transported to the spray block 9 through the delivery pipe 8 and sprayed from the nozzle on the spray block 9 to reduce dust. When the grinding is completed, the telescopic rod on the lifting device 4 shrinks and resets, which will drive the tooth block 21 to move upward. At this time, the tooth block 21 will drive the gear 24 to reverse and close the control valve 23, thereby achieving automatic dust reduction during grinding to prevent glass powder from being inhaled by surrounding workers and causing harm to their bodies. The dust-reducing water flow will be collected in the collection bucket 10 through the drainage trough 11.
