[0024] The present invention will be further described below with reference to the accompanying drawings: Example

[0025] Reference Figure 1-4 A grinding mill for water-based ink manufacturing includes a grinding cage 1, a circulation pipe 5, and a turbine pump 6. A discharge device is fixedly installed below the grinding cage 1 so that the ground material inside the grinding cage 1 can enter the circulation pipe 5 or be discharged from the grinding cage 1. A feeding hopper 4 is fixedly installed on the grinding cage 1 so that grinding material can be added to the grinding cage 1 through the feeding hopper 4. The feeding hopper 4 is connected to the grinding cage 1. Several perforations 14 are evenly distributed below the surface of the grinding cage 1 so that the ground material inside the grinding cage 1 can enter the discharge device through the perforations 14. The perforations 14 are located inside the discharge device. A first grinder and a second grinder are fixedly installed on the grinding cage 1 so that the grinding material inside the grinding cage 1 can be ground in multiple different directions, thereby improving grinding efficiency and grinding quality.

[0026] In this embodiment, one end of the circulation pipe 5 is fixedly connected to the discharge device, the other end of the circulation pipe 5 is fixedly connected to the feed port of the turbine pump 6, and the discharge port of the turbine pump 6 is fixedly connected to the feeding hopper 4, so that under the drive of the turbine pump 6, the raw material entering the discharge device is sucked into the circulation pipe 5, discharged into the feeding hopper 4 by the turbine pump 6, and finally discharged into the grinding cage 1 through the feeding hopper 4, so as to realize the circulation of materials and thus fully grind the raw material.

[0027] In this embodiment, the first grinder includes a motor 7 and a grinding disc 9. The motor 7 is fixedly installed on the outside of the grinding cage 1. The output end of the motor 7 rotates and extends into the inside of the grinding cage 1. The connection between the output end of the motor 7 and the grinding cage 1 is sealed. The grinding disc 9 is rotatably installed inside the grinding cage 1 and is fixedly connected to the output end of the motor 7 so that the grinding disc 9 can be driven by the motor 7 to rotate forward and backward inside the grinding cage 1, and grind the raw material during the rotation.

[0028] In this embodiment, the second grinder includes a second motor 8 and a second grinding disc 10. The second motor 8 is fixedly installed on the other side of the outside of the grinding cage 1. The output end of the second motor 8 rotates and extends into the inside of the grinding cage 1. The connection between the output end of the second motor 8 and the grinding cage 1 is sealed. The second grinding disc 10 is rotatably installed inside the grinding cage 1 and is fixedly connected to the output end of the second motor 8 so that the second motor 8 can drive the second grinding disc 10 to rotate forward and backward inside the grinding cage 1, and grind the raw material during the rotation.

[0029] In this embodiment, the discharge device includes a collection box 2 and a discharge pipe 3. The upper part of the collection box 2 is fixedly connected to the lower part of the grinding cage 1. The leakage hole 14 is located inside the collection box 2 so that the ground raw material can be temporarily stored through the collection box 2. The discharge pipe 3 is fixedly installed at the bottom of the collection box 2. The discharge pipe 3 is fixedly connected to one end of the circulation pipe 5 so that the ground raw material inside the collection box 2 can be discharged through the discharge pipe 3.

[0030] In this embodiment, a valve, such as a manual valve or a solenoid valve, is fixedly installed on the discharge pipe 3 to control the opening and closing of the discharge pipe 3.

[0031] In this embodiment, a first grinding chamber 11 is formed between the grinding disc 9 and the grinding cage 1. By setting the first grinding chamber 11, during the rotation of the grinding disc 9, a portion of the raw material is ground between the grinding disc 9 and the grinding cage 1.

[0032] In this embodiment, a second grinding chamber 12 is formed between the first grinding disc 9 and the second grinding disc 10. The second grinding chamber 12 is provided so that a portion of the raw material can be ground between the first grinding disc 9 and the second grinding disc 10.

[0033] In this embodiment, a third grinding chamber 13 is formed between the second grinding disc 10 and the grinding cage 1. By setting the third grinding chamber 13, during the rotation of the second grinding disc 10, a portion of the raw material is ground between the second grinding disc 10 and the grinding cage 1.

[0034] It should be noted that all electrical components involved in this case are controlled by a PLC controller.

[0035] Specifically, during grinding, the valve on the discharge pipe 3 is closed, the required grinding material is added to the grinding cage 1 through the feeding hopper 4, and the motor 7 and motor 8 are started, so that the motor 7 and motor 8 drive the grinding disc 9 and grinding disc 10 to rotate, and the raw material is ground by the rotation of the grinding disc 9 and grinding disc 10.

[0036] The rotation methods of grinding disc 1 (9) and grinding disc 2 (10) are as follows:

[0037] For example, grinding disc 9 and grinding disc 10 can be driven to rotate forward by simultaneously driving motor 7 and motor 8.

[0038] After the forward rotation, simultaneously drive grinding disc 9 and grinding disc 10 to reverse rotation.

[0039] After reversing, the grinding disc 9 is driven to rotate forward by motor 7, while the grinding disc 10 is driven to rotate in reverse by motor 8, or the grinding disc 9 is driven to rotate in reverse by motor 7, while the grinding disc 10 is driven to rotate forward by motor 8. By changing the rotation in this way, the raw material is fully ground. The ground raw material will fall into the collection box 2 for temporary storage.

[0040] Once the required amount of raw material is temporarily stored in the collection box 2, stop adding raw material to the grinding cage 1, start the turbine pump 6, and suck the raw material that has entered the discharge device into the circulation pipe 5. The material is then discharged into the feeding hopper 4 via the turbine pump 6, and finally discharged back into the grinding cage 1 through the feeding hopper 4. Grinding continues in the above manner, thereby realizing the circulation of materials and fully turning and grinding the raw material.

[0041] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
