The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model provides a cemented carbide powder grinding device, such as... Figure 1-5 As shown, the cemented carbide powder grinding equipment includes: a grinding chamber 2 formed on a grinding box 1 for grinding cemented carbide powder; a grinding block 3 rotatably mounted on the grinding box 1 for grinding the cemented carbide powder in the grinding chamber 2; a grinding mechanism disposed on the grinding box 1 and the grinding block 3 for driving the grinding block 3 to rotate and grind the cemented carbide powder in the grinding chamber 2; and a cooling mechanism assembled on the grinding box 1 and the grinding block 3 for cooling the grinding block 3.

[0023] In this embodiment, when grinding cemented carbide powder, a controller is first installed on one side of the device. The controller can control the entire device. The working principle of the controller is existing technology and will not be described in detail here. The controller starts the grinding mechanism to drive the grinding block 3 to rotate, and the cemented carbide powder is evenly fed into the grinding chamber 2. The gap between the grinding block 3 and the grinding chamber 2 gradually becomes smaller. The rotating grinding block 3 continuously squeezes and grinds the cemented carbide powder in the grinding chamber 2. At the same time, during the grinding process, the controller can start the cooling mechanism to cool the grinding block 3 according to the actual needs, thereby avoiding the problem of deformation of the grinding block 3 due to high temperature, ensuring the grinding effect of cemented carbide powder, and reducing the wear of the grinding block 3.

[0024] In a further preferred embodiment of the present invention, the grinding mechanism includes: a shaft tube 4 fixedly mounted on the grinding block 3; a mounting shaft 5 rotatably mounted on the grinding box 1, wherein bevel gears 6 are fixedly sleeved on both the mounting shaft 5 and the shaft tube 4, and the two bevel gears 6 mesh with each other; and a servo motor 7 fixedly mounted on one side outer wall of the grinding box 1, wherein the output shaft of the servo motor 7 is fixedly connected to one end of the mounting shaft 5.

[0025] In this embodiment, when using the grinding mechanism, the servo motor 7 is started by the controller to drive the mounting shaft 5 to rotate. Under the action of the bevel gear 6, the shaft tube 4 is driven to rotate, which in turn drives the grinding block 3 to rotate and squeeze and grind the cemented carbide powder in the grinding chamber 2, thereby completing the grinding work of the cemented carbide powder.

[0026] In a further preferred embodiment of this utility model, the cooling mechanism includes: a cooling pipe 8 fixedly installed on the grinding block 3; a feeding chamber 9 opened on the grinding block 3, the feeding chamber 9 being connected to one end of the cooling pipe 8; a placement box 10 fixedly installed on one side outer wall of the grinding box 1 for placing cooling water, the placement box 10 being provided with a semiconductor cooling chip 11 for cooling the cooling water in the placement box 10; a water pump 12 fixedly installed on the placement box 10, the water inlet end of the water pump 12 being connected to the placement box 10; a connecting pipe 13 fixedly installed on the grinding box 1, one end of the connecting pipe 13 being connected to the water outlet end of the water pump 12, and the other end of the connecting pipe 13 being sealed and rotatably connected to the grinding block 3 and connected to the feeding chamber 9; and a conduit 14 fixedly installed on the grinding box 1, the conduit 14 being sealed and rotatably connected to the shaft tube 4.

[0027] In this embodiment, when using the cooling mechanism, the controller activates the semiconductor cooling chip 11 to cool the cooling water in the placement box 10. A cooling fan is provided on one side of the placement box 10 to cool the semiconductor cooling chip 11. At the same time, a temperature sensor is provided on the placement box 10 to monitor the temperature of the cooling water in the placement box 10. Then, the water pump 12 is activated, and the cooling water enters the feeding chamber 9 through the connecting pipe 13, then enters the cooling pipe 8, and then flows back to the placement box 10 through the conduit 14. The low-temperature cooling water in the cooling pipe 8 carries away the heat on the grinding block 3, thereby cooling the grinding block 3. This cycle is repeated to cool the grinding block 3, preventing the grinding block 3 from deforming due to high temperature, thus ensuring the grinding effect on the cemented carbide powder and reducing the wear of the grinding block 3.

[0028] In a further preferred embodiment of this utility model, the grinding box 1 is provided with a sieving chamber 15, the sieving chamber 15 is connected to the grinding chamber 2, and the sieving chamber 15 is provided with a sieve plate 16 for sieving the ground cemented carbide powder. The sieving chamber 15 is provided with a plurality of connecting mechanisms, and the sieve plate 16 is connected to the sieving chamber 15 through the connecting mechanisms. The grinding box 1 is provided with a sieving mechanism for driving the sieve plate 16 to vibrate and sieve the cemented carbide powder.

[0029] In this embodiment, the ground cemented carbide powder falls onto the sieve plate 16. When the mounting shaft 5 rotates, it drives the screening mechanism. The screening mechanism vibrates the sieve plate 16 to screen the ground cemented carbide powder, thereby making the cemented carbide powder more in line with actual usage requirements.

[0030] In a further preferred embodiment of the present invention, the screening mechanism includes: a placement shaft 17 rotatably mounted on the grinding box 1, and a protrusion 18 for squeezing and vibrating the screen plate 16 is fixedly sleeved on the placement shaft 17; two synchronous pulleys 19 are respectively fixedly sleeved on the placement shaft 17 and the mounting shaft 5, and a synchronous belt 20 is sleeved on the two synchronous pulleys 19.

[0031] In this embodiment, when the mounting shaft 5 rotates, the interaction between the synchronous pulley 19 and the synchronous belt 20 drives the protrusion 18 on the mounting shaft 17 to rotate. The continuously rotating protrusion 18 squeezes the sieve plate 16, causing the sieve plate 16 to vibrate and sieve the ground cemented carbide powder, thereby making the cemented carbide powder more in line with actual use requirements.

[0032] In a further preferred embodiment of the present invention, the connecting mechanism includes: an installation groove 21 formed on the inner wall of the screening chamber 15; a connecting rod 22 fixedly installed in the installation groove 21, and a spring 23 sleeved on the connecting rod 22; and a slider 24 slidably installed on the connecting rod 22, the slider 24 being fixedly connected to the screen plate 16.

[0033] In this embodiment, when the placement shaft 17 drives the protrusion 18 to rotate, when the protrusion 18 presses the screen plate 16, the screen plate 16 drives the slider 24 to move on the connecting rod 22 to compress the spring 23. The connecting rod 22 is provided with a damping pad, which can absorb energy when the spring 23 deforms. When the protrusion 18 stops pressing the screen plate 16, the spring 23 returns to its original position. This process is repeated, so that the screen plate 16 vibrates to screen the ground cemented carbide powder, thereby making the cemented carbide powder more in line with actual usage requirements.

[0034] In a further preferred embodiment of the present invention, a guide hopper and a discharge pipe are respectively provided on one side and the bottom of the grinding box 1, and the guide hopper and the discharge pipe are used to discharge the screened cemented carbide powder.

[0035] In this embodiment, a guide hopper and a discharge pipe are used to discharge the sieved cemented carbide powder.

[0036] In summary, compared with related technologies, the entire device can grind cemented carbide powder and cool the grinding block 3, avoiding deformation of the grinding block 3 due to high temperature, thereby ensuring the grinding effect of cemented carbide powder and reducing wear of the grinding block 3.

[0037] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
