Then, the driving assembly 8 can drive the second grinding assembly 7 to rotate, so that the second grinding assembly 7 can rotate relative to the first grinding assembly 6, so that the first grinding assembly 6 and the second grinding assembly 7 can grind the introduced cosmetic raw materials, and the gap between the two is extremely small to ensure the fineness of the ground material. Then the ground raw materials will gather at the bottom of the inner cavity of the bucket shell 1, and then can flow to the collection assembly 9 through the discharge pipe 4. At this time, the collection assembly 9 can not only collect the ground raw materials, but also transport the ground raw materials in the collection assembly 9 to the feed hopper 3 under the pumping of the circulation assembly 10, so that the raw materials can enter the first grinding assembly 6 and the second grinding assembly 7 again, so that the raw materials can be repeatedly ground, ensuring the quality and effect of the cosmetic raw material grinding. By opening the discharge end of the collection assembly 9, the raw materials that meet the requirements can be discharged, which is convenient for the staff to use for subsequent processing.

[0031] See Figure 2-Figure 4 The first grinding assembly 6 includes a first grinding disc 61. A material guide hole 62 is opened on one side of the top surface of the first grinding disc 61, and the material guide hole 62 extends to the bottom surface of the first grinding disc 61.

Since the top end of the drive shaft 83 is inserted into the special-shaped hole 73 on the second grinding disc 71 through the special-shaped column 85, and the bottom end of the drive shaft 83 is connected to the motor 82, the second grinding disc 71 can be driven to rotate through the drive shaft 83 and the special-shaped column 85 through the motor 82, and the raw material can be ground.

One end of the pumping pipe 102 passes through the second through hole 95 and extends to the bottom of the inner cavity of the storage box 91. One end of the return pipe 103 is inserted into the side wall of the feed hopper 3.

[0040] Through the pumping pump 101 in the circulation component 10, the ground raw materials collected in the storage box 91 can be transported to the reflux pipe 103 through the pumping pipe 102, and then can flow into the feed hopper 3, so that the raw materials can enter the second grinding disc 71 and the first grinding disc 61 again, and then the raw materials can be circulated and ground. In addition, the circulation component 10 can also adopt a screw conveyor, so that the screw conveyor can return the ground raw materials collected directly from the storage box 91 to the feed hopper 3 again.

[0041] See Figure 1 , also includes a control switch 11, the control switch 11 is arranged on one side of the outer wall of the bucket shell 1; through the control switch 11, the staff can flexibly control the flexible operation of the equipment.

[0042] During operation, when it is necessary to grind the cosmetic raw materials, the staff can pour the raw materials into the feed hopper 3, so that the raw materials can be introduced into the first grinding assembly 6, and then the driving assembly 8 can drive the second grinding assembly 7 to rotate, so that the second grinding assembly 7 can rotate relative to the first grinding assembly 6, so that the first grinding assembly 6 and the second grinding assembly 7 can grind the introduced cosmetic raw materials, and the gap between the two is extremely small to ensure the fineness of the ground material. Then the ground raw materials will gather at the bottom of the inner cavity of the bucket shell 1, and then can flow to the collection assembly 9 through the discharge pipe 4. At this time, the collection assembly 9 can not only collect the ground raw materials, but also transport the ground raw materials in the collection assembly 9 to the feed hopper 3 under the pumping of the circulation assembly 10, so that the raw materials can enter the first grinding assembly 6 and the second grinding assembly 7 again, so that the raw materials can be repeatedly ground, ensuring the quality and effect of the cosmetic raw material grinding, and by opening the discharge end of the collection assembly 9, the raw materials that meet the requirements can be discharged, which is convenient for the staff to prepare and use later.

[0043] Through the pressure column 63 in the first grinding assembly 6, it can be installed on the inner wall of the bucket shell 1 through the stabilizing frame 64, and the first grinding disc 61 can be installed and fixed, so that the second grinding assembly 7 can remain stable during high-speed rotation. Then, through the material guide hole 62, it can be conveniently connected with the feed hopper 3, so that the raw materials can be easily introduced into the first grinding disc 61, and then the raw materials can be introduced into the grinding area of ​​the first grinding disc 61 and the second grinding assembly 7, so that the raw materials can be ground.

Therefore, under the drive of the driving assembly 8, the second grinding disc 71 can be driven to rotate through the special-shaped hole 73, and the pressure column 63 and the shaft hole 72 are plugged and connected, thereby ensuring that the second grinding disc 71 remains stable during rotation, so that the second grinding disc 71 can cooperate with the first grinding disc 61 to efficiently grind the cosmetic raw materials.

[0045] Through the shaft seal 84 in the drive assembly 8, it can be embedded in the center position of the bottom surface of the bucket-shaped shell 1, and the drive shaft 83 can be installed. Since the top end of the drive shaft 83 is inserted into the special-shaped hole 73 on the second grinding disc 71 through the special-shaped column 85, and the bottom end of the drive shaft 83 is connected to the motor 82, the second grinding disc 71 can be driven to rotate through the drive shaft 83 and the special-shaped column 85 through the motor 82, and the raw material can be ground. Through the stabilizing plate 81, it can be fixed on the bucket-shaped shell 1 and provide stable support for the motor 82 and the collecting assembly 9.

[0046] The storage box 91 in the collection component 9 can be stably installed on the stabilizing plate 81, and can be connected to the discharge pipe 4 through the first through hole 92, so that the ground raw materials can be collected.

Then, through the second through hole 95 on the storage box 91, the circulation component 10 can be conveniently plugged in and installed, so that the circulation component 10 can conveniently extract the raw materials in the storage box 91 for subsequent circulation grinding.

[0047] Through the pumping pump 101 in the circulation component 10, the ground raw materials collected in the storage box 91 can be transported to the reflux pipe 103 through the pumping pipe 102, and then can flow into the feed hopper 3, so that the raw materials can enter the second grinding disc 71 and the first grinding disc 61 again, and then the raw materials can be circulated and ground. In addition, the circulation component 10 can also adopt a screw conveyor, so that the screw conveyor can return the ground raw materials collected directly from the storage box 91 to the feed hopper 3 again.
