[0026] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0028] like Figures 1 to 8 As shown, a grinding device for precision machining of quartz stone comprises a cabinet 1, wherein a crushing roller 2 is arranged in the cabinet 1, a grinding cylinder 3 is fixedly connected to a position below the crushing roller 2 in the cabinet 1, a lifting mechanism is rotatably connected to the bottom end of the grinding cylinder 3, a screening mechanism is fixedly connected to the inner wall of the grinding cylinder 3 close to the lifting mechanism, and a grinding roller 4 is fixedly connected to the side of the screening mechanism away from the lifting mechanism.

[0029] The crushing roller 2 is set to break the large pieces of quartz stone into small pieces and enter the grinding cylinder 3. The quartz stone is ground by the lifting mechanism and grinding roller 4. The quartz stone is ground to the required specifications. The lifting mechanism and the screening mechanism are separated by the movement of the lifting mechanism, so that the ground quartz stone can be discharged, and the screening mechanism can intercept the quartz stone that does not meet the requirements to avoid direct discharge of the quartz stone that does not meet the requirements and produce defective products. When the lifting mechanism and the screening mechanism are in contact, the screening mechanism will drive the quartz stone that does not meet the requirements directly to the grinding area for the next grinding. The transmission distance is short, the overall grinding efficiency is high, and the noise is low.

[0030] In one embodiment, Figure 1 and Figure 2 As shown, the lifting mechanism includes a rotating shaft 5 rotatably connected to the bottom end of the grinding cylinder 3, one end of the rotating shaft 5 located in the grinding cylinder 3 is fixedly connected to a rotating disk 6, and the rotating disk 6 is fixedly connected with a rotating block 7 along the radial direction symmetrically. A grinding disk 8 is provided at a position of the grinding cylinder 3 close to the rotating disk 6, a mounting groove 9 is provided at the bottom end of the grinding disk 8, a spiral groove 10 is provided at the position of the grinding disk 8 located in the mounting groove 9, the rotating block 7 is located in the spiral groove 10 and is slidably connected to the grinding disk 8, a boss 11 is fixedly connected to the side of the grinding disk 8 away from the rotating disk 6, a motor 12 is fixedly connected to the bottom end of the cabinet 1, and the output shaft of the motor 12 is fixedly connected to the rotating shaft 5.

[0031] The forward rotation of the motor 12 drives the rotating shaft 5 to rotate, the rotation of the rotating shaft 5 drives the rotating disk 6 to rotate, the rotation of the rotating disk 6 drives the rotating block 7 to rotate, the rotating block 7 rotates in the spiral groove 10, so that the rotating disk 6 rises, and the rotating disk 6 is close to the grinding roller 4, which is convenient for grinding the quartz stone. When the rotating block 7 rotates to the end of the spiral groove 10, the rotation of the rotating block 7 will drive the rotating disk 6 to rotate continuously, thereby continuously grinding the quartz stone. When the motor 12 is reversed, the above process is opposite, and the rotating disk 6 is separated from the grinding roller 4 for unloading.

[0032] In one embodiment, Figure 3 , Figure 5 and Figure 6As shown, the screening mechanism includes a grinding support table 13 fixedly connected to the inner wall of the grinding cylinder 3, and the grinding support table 13 is symmetrically provided with sliding grooves 14 along the radial direction on one side close to the grinding disc 8, and a first sliding shaft 15 is fixedly connected in each of the sliding grooves 14, and a sliding block 16 is sleeved on the first sliding shaft 15 for sliding connection, and a first spring 17 is sleeved on the first sliding shaft 15, and a connecting rod 18 is fixedly connected to one end of the sliding block 16 outside the sliding groove 14, and a supporting rod 19 is fixedly connected to the end of the connecting rod 18 away from the sliding block 16, and a first connecting groove 20 is provided at one end of the supporting rod 19, and the supporting rod 19 has a first connecting groove 20, and the supporting rod 1 9 is fixedly connected with a mounting rod 21 at one end away from the first connecting groove 20, and the mounting rod 21 and the end of the support rod 19 away from the connecting rod 18 are both fixedly connected with a first blocking rod 22, and the support rod 19 is provided with a second connecting groove 23 at a position located in the first connecting groove 20, and a second sliding shaft 24 is fixedly connected in the second connecting groove 23, and a plurality of second blocking rods 25 are slidably connected on the second sliding shaft 24, and a connecting rod 26 is rotatably connected between two adjacent second blocking rods 25, and a placement groove 27 is provided at a position of the grinding support table 13 near the second sliding shaft 24, and a blocking member is provided in the placement groove 27.

[0033] When the grinding disc 8 descends, the grinding disc 8 will no longer block the second blocking rod 25. Under the action of the first spring 17, the slider 16 moves, and the movement of the slider 16 drives the connecting rod 18 to move. The movement of the connecting rod 18 drives the support rod 19 to move. The movement of the support rod 19 drives the installation rod 21 to move. The movement of the support rod 19 and the installation rod 21 drives the first blocking rod 22 and the second blocking rod 25 to move. During the next grinding process, the quartz stone that does not meet the requirements is driven onto the grinding disc 8. The distance driven to move the quartz stone is shorter, which improves the overall grinding efficiency, and there is no vibration and the noise generated is lower. At this time, the support rod 19 and the installation rod 21 both move toward the axis of the grinding cylinder 3. Therefore, the mounting rod 21 will gradually penetrate into the first connecting groove 20 of the support rod 19, driving the second blocking rod 25 to move, and the movement of the second blocking rod 25 drives the connecting rod 26 to move, so that the multiple second blocking rods 25 are close to each other, and do not block the movement of the support rod 19 and the mounting rod 21, and at the same time drive the quartz stone that does not meet the requirements to move to the grinding disk 8 for the next grinding. When moving to the grinding disk 8, the slider 16 will touch the blocking member, and the blocking member will close the space between the grinding support platform 13 and the grinding disk 8 to prevent the quartz stone that does not meet the requirements from moving out of the grinding disk 8 again. When the rotating disk 6 rises, contrary to the above process, the grinding disk 8 pushes the blocking member and keeps it in the placement groove 27.

[0034] In one embodiment, Figure 4As shown, the blocking member includes a blocking plate 28 slidably connected to the placement groove 27, a slot 29 is provided on the blocking plate 28 on one side close to the connecting rod 18, the grinding support table 13 is rotatably connected with a rotating rod 30 near the slot 29, a third connecting groove 31 is provided on the rotating rod 30, a connecting shaft 32 is slidably connected in the third connecting groove 31, and an end of the connecting shaft 32 located outside the third connecting groove 31 is fixedly connected with a clamping rod 33, and an end of the clamping rod 33 away from the connecting shaft 32 is clamped with the blocking plate 28 through the slot 29, and a second spring 34 is connected between the clamping rod 33 and the grinding support table 13.

[0035] The movement of the slider 16 will touch the connecting block 35 under the action of the first spring 17. The movement of the connecting block 35 drives the rotating rod 30 to rotate. The rotation of the rotating rod 30 drives the connecting shaft 32 to rotate. The rotation of the connecting shaft 32 drives the clamping rod 33 to move. The clamping rod 33 moves out of the clamping slot 29. The blocking plate 28 will fall under the action of gravity, and the space between the grinding support platform 13 and the grinding disk 8 is closed to prevent the quartz stone that does not meet the requirements from moving out of the grinding disk 8 again. When the grinding disk 8 rises, the grinding disk 8 will push the blocking plate 28 to gradually enter the placement groove 27. Under the action of the second spring 34, the clamping rod 33 is pushed into the clamping slot 29 to keep the blocking plate 28 in the placement groove 27. In this process, the blocking plate 28 keeps the space between the grinding support platform 13 and the grinding disk 8 in a closed state to prevent the quartz stone that does not meet the requirements from moving out of the grinding disk 8, so that the grinding support platform 13 and the grinding disk 8 cannot be completely in contact, resulting in poor grinding effect.

[0036] In one embodiment, Figure 4 As shown, one end of the second spring 34 abuts against the end of the clamping rod 33 away from the blocking plate 28, and the other end of the second spring 34 abuts against the grinding support table 13. The second spring 34 enables the clamping rod 33 to enter the clamping groove 29, so that the blocking plate 28 remains in the placement groove 27.

[0037] In one embodiment, Figure 3 As shown, one end of the first spring 17 abuts against the slider 16, and the other end of the first spring 17 abuts against the grinding support table 13, so that the slider 16 can push the slider 16 to move when the grinding disk 8 descends, and then the blocking plate 28 closes the space between the grinding support table 13 and the grinding disk 8.

[0038] In one embodiment, Figure 5 and Figure 7As shown, one end of each mounting rod 21 away from the support rod 19 is located in the first connecting groove 20 on the adjacent support rod 19, and is slidably connected to the adjacent support rod 19, so that the support rod 19 and the mounting rod 21 can move relative to each other, ensuring that the quartz stone that does not meet the requirements will not move out of the grinding cylinder 3.

[0039] In one embodiment, Figure 5 and Figure 6 As shown, one of the second blocking rods 25 close to the mounting rod 21 is fixedly connected to the support rod 19, so that when the mounting rod 21 gradually penetrates into the first connecting groove 20, it can drive multiple second blocking rods 25 to approach each other without blocking the movement of the support rod 19 and the mounting rod 21.

[0040] In one embodiment, Figure 4 As shown, one end of the rotating rod 30 away from the clamping rod 33 is fixedly connected to a connecting block 35, and one end of the connecting block 35 extends into the sliding groove 14. When the slider 16 touches the connecting block 35 and moves, it can drive the rotating rod 30 to rotate.

[0041] In one embodiment, Figure 3 As shown, the end of the grinding disc 8 close to the grinding support platform 13 is provided with an inclined surface to facilitate the movement of the first blocking rod 22 and the second blocking rod 25.
