[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0038] Example 1:

[0039] like Figures 2 to 5 As shown, this utility model discloses a grinding machine, including a base 1, a grinding rotor 2, a drive motor 3, and a grinding cylinder 4.

[0040] Specifically, the grinding rotor 2 is mounted on the base 1, and the end of the grinding rotor 2 is provided with a feed shell 5. The grinding rotor 2 drives the grinding medium to move by rotating and grinds the material to be ground.

[0042] The grinding cylinder 4 is movably mounted on the base 1 via the guide rail frame 6. The grinding cylinder 4 slides along the guide rail frame 6 and is sleeved outside the grinding rotor 2. The end of the grinding cylinder 4 is detachably connected to the feed shell 5.

[0043] In this embodiment, a grinding medium filling port 18 is provided at the top of the grinding cylinder, through which grinding medium can be added into the grinding cylinder 4. When it is necessary to replace the grinding medium, the grinding cylinder 4 is disassembled from the feed shell 5, and the grinding medium inside the grinding cylinder 4 falls from below, completing the removal of the grinding medium. During the loading of grinding medium, the grinding cylinder 4 is gradually moved along the guide rail frame 6, and grinding medium is added to different positions of the grinding rotor 2 through the grinding medium filling port 18. When the grinding cylinder 4 and the feed shell 5 are closed, the grinding cylinder 4 is fixed to the feed shell 5 with bolts, at which point the grinding operation of the material can be performed.

[0044] It should be noted that the grinding media generally uses grinding balls, and their specific structure and grinding process will not be described in detail here.

[0045] Furthermore, the grinding rotor includes a drive shaft 7, a spiral feeder 8, a rotor drive, and a grinding media dispersant.

[0046] Specifically, the spiral feeder 8 is fixedly disposed at the end of the drive shaft 7, and the spiral feeder 8 is used to convey the material to be ground.

[0047] The rotor driving member is arranged on the driving shaft 7, and is used to drive the grinding medium to move and grind the material to be ground.

[0048] The grinding medium dispersing member is arranged at the end of the driving shaft 7 away from the screw feeding member 8, and is used to disperse the grinding medium and discharge the ground material.

[0049] In the embodiment, the feeding shell 5 is arranged outside the screw feeding member 8, and the feeding shell 5 has a feeding port 14. The driving motor 3 is connected with the driving shaft 7 through the shaft coupling 15. When the material needs to be ground, the driving motor 3 is started, and the driving shaft 7 rotates under the driving of the driving motor 3. The material to be ground enters the middle part of the grinding cylinder 4 under the conveying of the screw feeding member 8 from the feeding port 14. At this time, the rotor driving member drives the grinding medium to move and grind the material to be ground. The material gradually moves to the side of the grinding medium dispersing member during the grinding process. The grinding medium dispersing member disperses the grinding medium, and the ground material can be discharged from the gap between the dispersed grinding medium, and the grinding operation of the material is completed.

[0050] The rotor driving member includes a plurality of first rotors 9 and a plurality of second rotors 10. The first rotors 9 and the second rotors 10 are arranged on the driving shaft 7. The first rotors 9 and the second rotors 10 are staggered. The second rotors 10 are used to separate the grinding medium in the first rotors 9. The second rotors 10 are provided with through holes 11 for the material to pass through.

[0051] In addition, the grinding medium dispersing member includes a transmission positioning disc 12 and a dispersing disc 13. The transmission positioning disc 12 is detachably installed on the driving shaft 7, and is used to limit and fix the first rotors 9 and the second rotors 10. The dispersing disc 13 is installed on the side circumferential wall of the transmission positioning disc 12. The dispersing disc 13 is arranged in an arc shape. A plurality of dispersing discs 13 are circumferentially distributed on the side circumferential wall of the transmission positioning disc 12.

[0053] Specifically, the dispersing disc 13 is in close contact with the inner side of the filter screen 16. During the rotation of the driving shaft 7, the dispersing disc 13 can disperse the grinding medium at the bottom of the grinding cylinder 4, so as to avoid the accumulation of the grinding medium and block the ground material, and ensure the smooth discharge of the ground material.

[0054] In order to facilitate the collection of the ground material, the filter screen 16 is externally provided with a receiving shell 17, and the receiving shell 17 is fixedly installed on the grinding cylinder 4. The ground material passes through the filter screen 16 into the receiving shell 17 for collection and is discharged from the outlet of the receiving shell 17.

[0055] Embodiment 2:

[0056] As Figure 1 The utility model discloses a kind of nano grinder continuous feeding control systems, applied to grinder, including controller, temperature sensor, current sensor and discharging solenoid valve.

[0057] The controller input end is electrically connected with the temperature sensor and the current sensor, and the controller output end is electrically connected with the driving motor of nano grinder and the discharging solenoid valve.

[0058] The temperature sensor is installed in the grinding cavity of nano grinder, and the temperature sensor is used to monitor the temperature in the grinding cavity of nano grinder.

[0059] The current sensor is arranged at the driving motor power supply line of nano grinder, and the current sensor is used to monitor the real-time working current of the driving motor of nano grinder.

[0060] Specifically, the controller input end is electrically connected with the temperature sensor and the current sensor, and the controller output end is electrically connected with the driving motor 3 and the discharging solenoid valve.

The current sensor is arranged at the driving motor 3 power supply line, and the current sensor is used to monitor the real-time working current of the driving motor 3.

[0061] In the embodiment, the current sensor is sleeved on the single power supply line of the driving motor, and is used to monitor the real-time working current of the driving motor. Since the working voltage of the driving motor is certain, the real-time power of the driving motor can be obtained by monitoring the real-time current of the driving motor. The temperature sensor is arranged in the grinding cylinder 4, and is used to monitor the temperature of the grinding material in the grinding cylinder, so as to avoid denaturation of the grinding material caused by too high temperature in the grinding cylinder. During the working process of the grinder, the working mode of the control system is as follows:

[0062] When the temperature sensor in the grinding cylinder 4 monitors that the temperature exceeds 150 DEG C or the current sensor monitors that the current of the driving motor is greater than or equal to the rated current, the controller controls the driving motor and the discharging solenoid valve to be closed, so as to avoid denaturation of the grinding material caused by too high temperature in the grinding cylinder 4, and ensure the safety of the driving motor 3. In this case, the control system adopts protection mode.

[0063] When the temperature sensor in the grinding cylinder 4 monitors the temperature to be more than 120 DEG C or the current sensor monitors the current of the driving motor to be greater than or equal to 80% of the rated current, the controller controls the discharging electromagnetic valve to be closed, at this time, the driving motor 3 continues to work, the grinder grinds the material, and the ground material is discharged quickly.

[0064] When the temperature sensor in the grinding cylinder 4 monitors the temperature to be more than 105 DEG C or the current sensor monitors the current of the driving motor to be greater than or equal to 70% of the rated current, the controller controls the discharging electromagnetic valve to discharge at 50%-80% of the maximum discharging speed.
