The holding mechanism is located above the grinding roller. There are bearing seats on both sides of the grinding roller, and a movable plate is located below the bearing seats. The bearing seats are fixed to the movable plate. A second motor and a reciprocating mechanism are located on one side of the movable plate. A pulley is located on the output shaft of the second motor. The pulley is connected to the grinding roller via a conveyor belt. A base plate is slidably connected below the movable plate. The reciprocating mechanism includes a first motor. A wheel is located on the output shaft of the first motor. The wheel is eccentrically connected to a connecting rod. The other end of the connecting rod is connected to the base plate.

[0006] As a preferred embodiment of the present invention, the grinding roller includes a rotating shaft, a stop block is fixedly connected to one side of the rotating shaft, and a support block is fixedly connected to the other side of the rotating shaft. A sand roller is mounted on the support block and the stop block. The support block and the stop block are used to fix the sand roller to the rotating shaft to achieve synchronous rotation.

[0007] As a preferred embodiment of this utility model, the support block and the stop block are in the shape of bosses. The maximum diameter of the stop block is greater than the inner diameter of the sand roller. The sand roller is slidably connected to the minimum diameter of the stop block. The maximum diameter of the support block is the same as the minimum diameter of the stop block. The minimum diameter of the support block is provided with threads, and a nut is connected to the threads. The outer diameter of the nut is greater than the inner diameter of the sand roller. When the nut is removed, the sand roller can be slid directly toward the support block, thereby realizing the quick disassembly of the sand roller.

There is a bearing between component one and component two. The bearing is fixed to both sides of the rotating shaft. The end of the rotating shaft is provided with pulley two. The conveyor belt connects pulley one and pulley two. Before disassembling the sand roller, component one and component two need to be separated first, so as to carry out the disassembly of the sand roller.

[0009] In a preferred embodiment of this invention, a slider is fixedly connected to the bottom of the movable plate, and a slide rail is fixedly connected to the top of the base plate. The movable plate is slidably connected to the base plate via the slider and the slide rail.

[0010] As a preferred technical solution of this utility model, a connecting plate is provided on the side of the base plate, and the connecting rod is rotatably connected to the connecting plate. When the reciprocating mechanism rotates, the connecting rod and the connecting plate drive the movable plate to reciprocate around the base plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses the movable plate to slide and connect to the base plate via the slider and the slide rail. The eccentric position of the rotating wheel is connected to the connecting rod, and the other end of the connecting rod is connected to the base plate, so as to realize the linear reciprocating motion of the movable plate, thereby preventing the gemstone from being polished at one point on the sanding roller for a long time, which would cause the sanding roller to become uneven. By separating the first component and the second component, and then separating the nut from the support block, the sanding roller can slide directly towards the support block, thereby enabling the quick replacement of the sanding roller.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1 to 7As shown, this utility model discloses a gemstone grinding mechanism. The technical solution includes a clamping mechanism and a grinding roller 3. The clamping mechanism is located above the grinding roller 3. Bearing seats 6 are located on both sides of the grinding roller 3, and a movable plate 2 is located below the bearing seats 6. The bearing seats 6 are fixed to the movable plate 2. The grinding roller 3 includes a rotating shaft 301. A stop block 303 is fixedly connected to one side of the rotating shaft 301, and a support block 304 is fixedly connected to the other side of the rotating shaft 301. A sand roller 302 is mounted on the support block 304 and the stop block 303. The support block 304 and the stop block 303 are boss-shaped. The maximum diameter of the stop block 303 is larger than the inner diameter of the sand roller 302. The sand roller 302 is slidably connected to the minimum diameter of the stop block 303. The maximum diameter of the support block 304 is the same as the minimum diameter of the stop block 303. A thread is provided on the minimum diameter of the support block 304, and a nut 305 is connected to the thread. The outer diameter of the nut 305 is larger than the inner diameter of the sand roller 302. The bearing housing 6 includes component 1 601 and component 2 602. Component 1 601 is detachably connected. There is a bearing 603 between component 1 601 and component 2 602. The bearing 603 is fixed to both sides of the rotating shaft 301. The end of the rotating shaft 301 is provided with pulley 2 7. There is motor 2 5 and reciprocating mechanism 4 on one side of the movable plate 2. There is pulley 1 501 on the output shaft of motor 2 5. The conveyor belt connects pulley 1 501 and pulley 2 7. The bottom of the movable plate 2 is fixedly connected to the slider 201. The top of the base plate 1 is fixedly connected to the slide rail 101. The movable plate 2 is slidably connected to the base plate 1 through the slider 201 and the slide rail 101. The reciprocating mechanism 4 includes motor 1 401. There is a rotating wheel 402 on the output shaft of motor 1 401. The rotating wheel 402 is eccentrically connected to the connecting rod 403. There is a connecting plate 102 on the side of the base plate 1. The connecting rod 403 is rotatably connected to the connecting plate 102.

[0023] The working principle of this utility model is as follows: Motor 2 5 is started, and Motor 2 5 drives the sand roller 302 to rotate through pulley 2 7, conveyor belt and pulley 1 501. Motor 1 401 is started, and Motor 1 401 causes the movable plate 2 to make linear reciprocating motion through rotating wheel 402, connecting rod 403, slider 201 and slide rail 101. At this time, the clamping mechanism clamps the gemstone and touches the sand roller 302. The sand roller 302 polishes the gemstone through its own rotation and linear reciprocating motion. When the sand roller 302 is severely worn after long-term use, component 2 602 is separated from component 1 601, and the rotating shaft 301 is taken out as a whole. Then the nut 305 is separated from the support block 304. At this time, the sand roller 302 can slide directly towards the support block 304, thereby replacing the sand roller 302.
