[0024] This invention proposes a stirring device for use in a grinding mill.

[0025] Please see Figure 1 In one embodiment of this utility model, the stirring device applied to a grinding machine is used for grinding plates. The stirring device for the grinding machine includes: a cylinder 1, a controller, and a stirring assembly 2, a spraying assembly 3, and a detection assembly disposed on the cylinder 1. The controller is electrically connected to the stirring assembly 2, the spraying assembly 3, and the detection assembly. The cylinder 1 has a receiving cavity 11 for storing grinding fluid. A feeding mechanism 4 is provided, and both the feeding mechanism 4 and the spraying assembly 3 are connected to the receiving cavity 11. The feeding mechanism 4 is electrically connected to the controller and is used to supply water and / or abrasive to the receiving cavity 11. The stirring assembly 2 is used to stir the water and abrasive in the receiving cavity 11 to form grinding fluid. The detection assembly is used to detect the concentration of the grinding fluid in the receiving cavity 11.

[0026] The stirring device applied to the grinding machine has a grinding mode, and the stirring device applied to the grinding machine also has at least one of a discharge mode and a cleaning mode. In the grinding mode, the spray assembly 3 is used to extract and transport the grinding liquid in a first preset concentration range to the board. In the discharge mode, the spray assembly 3 is used to extract the grinding liquid in a second preset concentration range and discharge it outside the receiving cavity 11. The second preset concentration range is smaller than the first preset concentration range. In the cleaning mode, the stirring assembly 2 is used to stir water and the grinding liquid in the second preset concentration range to form a grinding liquid in a third preset concentration range. The spray assembly 3 is used to extract and discharge the grinding liquid in the third preset concentration range outside the receiving cavity 11.

[0027] The technical solution of this utility model adopts a grinding machine with grinding mode, discharge mode and cleaning mode. In the discharge mode, the spray assembly 3 draws out the grinding liquid in the second preset concentration range and discharges it to the outside of the receiving cavity 11, so that the grinding liquid in the receiving cavity 11 is emptied. In the cleaning mode, the feeding mechanism 4 adds water to the receiving cavity 11, and the stirring assembly 2 stirs the water and the remaining grinding liquid in the second preset concentration range to form the grinding liquid in the third preset concentration range, so that the grinding liquid adhering to the inner wall of the receiving cavity 11 is washed away. The grinding liquid in the third preset concentration range is drawn out and discharged to the outside of the receiving cavity 11 by the spray assembly 3, so that the grinding machine has the functions of automatic discharge and automatic cleaning, reducing the cost of manual cleaning, reducing the difficulty of cleaning the grinding machine, and improving the cleaning efficiency of the grinding machine cylinder 1.

[0028] In this embodiment, the stirring device applied to the grinding machine can be used for the grinding process of a plate, such as a flexible circuit board. The controller can be a PLC system, electrically connected to the stirring assembly 2, the spraying assembly 3, the feeding mechanism 4, and the detection assembly, to control the operation of each component. The stirring device applied to the grinding machine may also include a frame, with the cylinder 1 and the feeding mechanism 4 mounted on the frame. The stirring assembly 2, the spraying assembly 3, and the detection assembly are mounted on the cylinder 1, with the stirring assembly 2 located on one side of the spraying assembly 3. The cylinder 1 has a receiving cavity 11 for storing grinding fluid. The feeding mechanism 4 is located on one side of the cylinder 1 and communicates with the receiving cavity 11, facilitating the feeding mechanism 4 to supply water and / or abrasive to the cylinder 1. At least a portion of the stirring assembly 2 and at least a portion of the spraying assembly 3 are located within the receiving cavity 11, facilitating the stirring assembly 2 to stir the liquid within the receiving cavity 11 and facilitating the spraying assembly 3 to extract the liquid from the receiving cavity 11. To improve the accuracy of the grinding slurry concentration, this application also employs a detection component to monitor the real-time concentration of the grinding slurry within the receiving cavity 11. When the real-time concentration of the grinding slurry is lower than the concentration required for production, the controller sequentially coordinates the feeding mechanism 4 and the stirring component 2 to restore the real-time concentration of the grinding slurry to the required concentration. The abrasive can be powdered volcanic ash, etc. The abrasive and water can be mixed under the stirring of the stirring component 2 to form a grinding slurry, which is then sprayed onto the board through the spray nozzle by the spray component 3, thereby improving the board production efficiency. When the grinding slurry in the receiving cavity 11 is repeatedly used for more than twenty hours, the concentration of the grinding slurry may become consistent with the second preset concentration range. If the second preset concentration range is smaller than the first preset concentration range, the user needs to replace all the grinding slurry in the receiving cavity 11. In the above situation, the user can control the stirring device applied to the grinding machine to be in discharge mode through the controller, and the spray component 3 will extract the grinding slurry in the receiving cavity 11 and discharge it out of the receiving cavity 11 through the discharge pipe. To ensure the grinding fluid in the receiving cavity 11, which is within the second preset concentration range, is thoroughly cleaned, the user can control the agitator of the grinding machine to enter cleaning mode via the controller. The controller then controls the feeding mechanism 4 to repeatedly add clean water to the receiving cavity 11. The agitator 2 mixes the water and the grinding fluid in the second preset concentration range to form a grinding fluid in the third preset concentration range, which is lower than the second preset concentration range. The spray assembly 3 extracts and discharges the grinding fluid outside the receiving cavity 11, thus cleaning the inner wall of the receiving cavity 11. After multiple cleanings of the receiving cavity 11, the user can also control the agitator of the grinding machine to enter grinding mode via the controller. The controller then controls the feeding mechanism 4 to add clean water and abrasive to the receiving cavity 11. The controller controls the agitator 2 to mix the water and abrasive in the receiving cavity 11 to form a grinding fluid in the first preset concentration range. The spray assembly 3 then sprays the grinding fluid onto the plate through the spray nozzle.The grinding machine of this application can automatically discharge materials, automatically clean, and automatically prepare grinding fluid, saving maintenance costs and reducing labor costs.

[0029] like Figure 1 As shown, in one embodiment, the stirring assembly 2 further includes a stirrer 21 and a first driving member 22. The first driving member 22 is driven and connected to the stirrer 21 and electrically connected to the controller. The stirrer 21 is disposed in the receiving cavity 11, and the first driving member 22 is disposed on the cylinder 1.

[0030] In this embodiment, the first driving component 22 can be configured as a motor or other driving component. The first driving component 22 can be mounted on the cylinder 1 and located outside the receiving cavity 11 to prevent liquid in the receiving cavity 11 from splashing onto the first driving component 22 and causing corrosion. The output end of the first driving component 22 can be driven to connect to the connection end of the stirrer 21, and the stirring end of the stirrer 21 can extend into the receiving cavity 11. The stirrer 21 rotates under the drive of the first driving component 22, which makes it easier for the stirrer 21 to stir the liquid in the receiving cavity 11, so that the water can clean the residual grinding fluid on the inner wall of the receiving cavity 11 under the stirring of the stirrer 21, thereby improving the cleaning efficiency of the stirrer 21 on the inner wall of the receiving cavity 11.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, the feeding mechanism 4 includes a water supply component 41 for supplying water into the receiving cavity 11 and a feeding component 42 for supplying abrasive into the receiving cavity 11. The water supply component 41 is connected to the receiving cavity 11, and the discharge port of the feeding component 42 is connected to the receiving cavity 11. The discharge port of the feeding component 42 is located above the stirring component 2.

[0032] In this embodiment, the water-adding component 41 adds water to the receiving cavity 11, thereby facilitating the control of the water volume within the cavity 11. The application also uses a feeding component 42 to add powdered abrasive to the receiving cavity 11, further facilitating the control of the real-time concentration of the grinding fluid within the cavity 11, ensuring the grinding fluid concentration meets production requirements. The stirrer 21 mixes the powdered abrasive and water evenly to form the grinding fluid, and the stirrer 21 prevents solid sedimentation within the grinding fluid. The water-adding component 41, the feeding component 42, and the detection component can also be electrically connected to a controller. The controller can control the grinding fluid concentration by adjusting the amount of water and abrasive added based on the grinding fluid concentration detected by the detection component, thereby achieving automated detection and adjustment of the grinding fluid concentration.

[0033] like Figure 1As shown, in one embodiment, the feeding assembly 42 includes a feeding bin 421 and a feeder 422. The feeder 422 is located below the discharge port of the feeding bin 421. The discharge port of the feeding bin 421 is connected to the inlet of the feeder 422. The discharge port of the feeder 422 is connected to the receiving cavity 11.

[0034] In this embodiment, the feeder 422 can be configured as a screw feeder 422, and the loading bin 421 can be used to store abrasive. The feed inlet of the feeder 422 is located below the discharge outlet of the loading bin 421, and the discharge outlet of the loading bin 421 is connected to the feed inlet of the feeder 422, so that the abrasive is quickly conveyed into the feeder 422 through the discharge outlet of the loading bin 421 under the action of gravity, thereby improving the feeding speed of the loading assembly 42. The loading bin 421 may include a storage section and a loading section that are interconnected. The outer diameter of the loading section gradually decreases from the side closer to the storage section toward the side closer to the feeder 422, thereby improving the feeding efficiency of the loading section. After the feeder 422 is activated, it transports the powdered abrasive from the storage section to the feeding section. The powdered abrasive is then transported from the feeding section into the receiving cavity 11 by the feeder 422, thereby adding the powdered abrasive and increasing the concentration of the grinding fluid in the receiving cavity 11.

[0035] like Figure 1 As shown, in one embodiment, the stirring device applied to the grinding mill further includes a dust suction component 5 and a dust collection component 53. One end of the dust suction component 5 is connected to the feeding hopper 421, the dust suction component 5 is located above the feeding component 42, and the other end of the dust suction component 5 is connected to the dust collection component 53.

[0036] In this embodiment, the present application employs a dust suction component 5 and a dust collection component 53 working together to collect the dust generated by the feeding mechanism 4 during the feeding process into the dust collection component 53. One end of the dust suction component 5 is connected to the end of the feeding hopper 421 away from the feeder 422, and the other end of the dust suction component 5 is connected to the dust collection component 53. Under the operation of the dust suction component 5, the dust suction component 5 transports the dust from the sixth pipe into the dust collection component 53, thereby preventing the dust generated by the feeding mechanism 4 during the feeding process from flying around randomly.

[0037] In one embodiment, the dust collection assembly 53 may include a sixth pipe (not shown), a seventh pipe (not shown), a first collection chamber (not shown), and a second collection chamber (not shown). The sixth pipe connects to both the dust collection assembly 5 and the first collection chamber, allowing dust to be transported from the sixth pipe to the first collection chamber. The seventh pipe connects to both the first and second collection chambers, allowing dust to be transported from the first collection chamber to the second collection chamber, thereby improving dust collection efficiency.

[0038] like Figure 1As shown, in one embodiment, the vacuuming assembly 5 includes a vacuum cleaner 51 and a second driving member. The vacuum cleaner 51 is connected to the feeding bin 421, and the second driving member drives the vacuum cleaner 51. The vacuum cleaner 51 is connected to the dust collection assembly 53 through a third pipe 52.

[0039] In this embodiment, the second driving component can be configured as a motor or similar drive unit, and can be mounted on a frame. The output end of the second driving component can be driven to connect to the connection end of the vacuum cleaner 51, and the suction port of the vacuum cleaner 51 can be located inside the feeding bin 421. The vacuum cleaner 51 operates under the drive of the second driving component, so that a negative pressure is generated at the end of the feeding bin 421 away from the feeder 422, making it easier for the vacuum cleaner 51 to suck up the dust from the feeding bin 421. The dust is input into the first collection bin and the second collection bin through the sixth pipe and the seventh pipe, respectively, reducing the impact of dust on the normal feeding of the feeding assembly 42, thereby improving the dust collection efficiency.

[0040] like Figure 1 As shown, in one embodiment, the water filling assembly 41 includes a solenoid valve 411, a fourth pipe 412, and a level gauge 413. The solenoid valve 411 is connected in series with the fourth pipe 412. The solenoid valve 411 and the level gauge 413 are electrically connected to the controller in sequence. The solenoid valve 411 is used to control the opening and closing of the fourth pipe 412. One end of the fourth pipe 412 is connected to the receiving cavity 11, and the other end of the fourth pipe 412 is used to connect to an external water source. The level gauge 413 is located inside the receiving cavity 11.

[0041] In this embodiment, the water filling assembly 41 may include a fourth pipe 412, a level gauge 413, and a solenoid valve 411. The level gauge 413 is mounted on the cylinder 1. The level gauge 413 may be a float-type level gauge 413, used to detect the liquid level in the receiving cavity 11. The solenoid valve 411 is connected in series with the water pipe, and the controller controls the water flow rate into the receiving cavity 11 through the solenoid valve 411, thereby facilitating the adjustment of the liquid level in the receiving cavity 11. The solenoid valve 411 and the level gauge 413 are electrically connected to the controller in sequence, thereby realizing automatic control of the amount of water added to the receiving cavity 11.

[0042] like Figure 1 As shown, in one embodiment, the stirring device applied to the grinding mill further includes a pipe assembly 6 and a detection element 7. The detection element 7 is provided with a detection part 71. The pipe assembly 6 includes a conveying pipe 61 and a bypass pipe 62 that are interconnected. The spray assembly 3 is connected to the conveying pipe 61 and the bypass pipe 62 respectively. The detection element 7 is disposed in the bypass pipe 62 so that the detection part 71 can be inserted into the bypass pipe 62. The detection element 7 is electrically connected to the controller.

[0043] In this embodiment, the present application employs a detection element 7 mounted on the bypass pipe 62, allowing the detection unit 71 to be inserted into the bypass pipe 62 that delivers the polishing slurry. This facilitates automatic cleaning of the detection unit 71 by the high-speed, high-pressure polishing slurry, eliminating the need for manual cleaning and reducing the maintenance cost of the detection element 7. The polishing slurry also washes away impurities on the detection unit 71, thereby improving the stability of the detection element 7 in detecting the concentration of the polishing slurry. When the spray assembly 3 stops working, the polishing slurry on the bypass pipe 62 flows back into the receiving cavity 11 under the action of gravity, thus preventing the detection unit 71 from being immersed in the polishing slurry for a long time and improving the service life of the detection unit 71.

[0044] In this embodiment, the stirring device applied to the grinding mill further includes a first ball valve, a second ball valve, and a third ball valve. The first, second, and third ball valves can be configured as a solenoid valve 411, a pneumatic ball valve, or an electric ball valve. The first ball valve is connected in series with the bypass pipe 62 and is located between the detection element 7 and the spray assembly 3. The second ball valve is connected in series with the delivery pipe 61 and is located between the bypass pipe 62 and the delivery pipe 61. The third ball valve is connected in series with the bypass pipe 62 and is located between the detection element 7 and the delivery pipe 61. The first ball valve controls the opening and closing of the bypass pipe 62, facilitating control of the flow rate of the grinding fluid entering the bypass pipe 62. The second ball valve controls the opening and closing of the delivery pipe 61, facilitating control of the flow rate of the grinding fluid entering the delivery pipe 61. The third ball valve controls the flow rate of the grinding fluid from the bypass pipe 62 into the delivery pipe 61, facilitating control of the flow rate of the grinding fluid entering the delivery pipe 61. When the test piece 7 malfunctions and requires repair, the controller closes the bypass pipe 62 and opens the delivery pipe 61 normally to allow the grinding machine to continue normal production.

[0045] like Figure 1 As shown, in one embodiment, the stirring device applied to the grinding mill further includes a buffer 8, which is connected in series with the bypass pipe 62, and the detection element 7 is inserted into the buffer 8 so that the detection part 71 can be inserted into the buffer 8.

[0046] In this embodiment, the buffer element 8 is connected in series with the bypass pipe 62 and is located between the first ball valve and the second ball valve. The detection part 71 of the detection element 7 is inserted into the buffer element 8. The buffer element 8 may have a buffer chamber for storing the polishing slurry. The buffer chamber provides a stable detection environment to the detection element 7, thereby improving the stability and accuracy of the detection element 7 in detecting the polishing slurry. The shape of the buffer element 8 is not specifically limited; it can be drum-shaped or circular, as long as it can provide space for storing the polishing slurry.

[0047] like Figure 1As shown, in one embodiment, the stirring device applied to the grinding machine further includes a discharge pipe, and the spray assembly 3 includes a spray pump 31, which is disposed in the cylinder 1. One end of the spray pump 31 is connected to the receiving cavity 11, and the other end of the spray pump 31 is connected to the discharge pipe.

[0048] In this embodiment, the application employs a spray pump 31 and a discharge pipe in cooperation to better discharge the liquid from the receiving cavity 11. In cleaning mode, the spray pump 31 can extract the polishing liquid in the receiving cavity 11 within the third preset concentration range and discharge it to the outside of the receiving cavity 11 through the discharge pipe.
