[0002] In the preparation process of plastic masterbatch pigments, grinding is a crucial step. The purpose of this step is to refine the pigment particles to a suitable size to ensure that the pigment can be evenly and efficiently dispersed in the plastic matrix. Through grinding, the dispersibility and tinting strength of the pigment can be significantly improved, thereby improving the color uniformity and appearance quality of the final plastic product; the grinding process ensures good compatibility between the pigment particles and the plastic matrix, and is an indispensable step in the production of high-quality plastic masterbatch pigments.

[0003] In actual use, when changing materials of different colors or types, if they are not thoroughly cleaned, color bleeding is likely to occur. This is because the pigment particles remaining in the previous material may mix into the new material, causing color mixing and affecting the appearance quality of the product.

[0027] See also Figure 1-4 The utility model provides a technical solution: a plastic masterbatch pigment grinder, comprising a support assembly 1, a drive assembly 2 and a grinding assembly 3, wherein the drive assembly 2 is arranged at the lower end of the support assembly 1, the grinding assembly 3 is arranged at the upper end of the support assembly 1, the drive assembly 2 is connected to the grinding assembly 3, the support assembly 1 comprises a support shell 11, a grinding base 12 is fixed at the upper end of the support shell 11, the grinding assembly 3 comprises a grinding barrel 32, the grinding barrel 32 is mounted on the upper end of the grinding base 12, a rotating rod 31 is movably mounted inside the support shell 11, a grinding disc 34 is fixed at the upper end of the rotating rod 31, the grinding disc 34 is arranged inside the grinding base 12, limiting grooves 321 are provided on both sides of the grinding barrel 32, support rods 33 are installed in the limiting grooves 321 on both sides, grinding rollers 332 are installed on the support rods 33 through bearings 331, and the two groups of grinding rollers 332 can be driven to rotate relative to each other by the rotation of the grinding disc 34;

[0028] During use, the grinding barrel 32 and the grinding base 12 are tightly combined to form an easy-to-clean closed system. When cleaning is required, it is only necessary to inject a cleaning liquid such as water or a special cleaning agent into the grinding barrel 32 to thoroughly clean the inside of the grinding barrel 32 and the grinding parts in contact with it, effectively removing residual pigment particles and avoiding color bleeding problems; the rotating rod 31, as a key component of power transmission, transmits the power of the driving assembly 2 to the grinding disc 34 to rotate; the grinding disc 34 directly contacts the pigment material and grinds the pigment through the grinding roller 332 and the leakage hole 341 on its surface.

[0029] The driving assembly 2 includes a driving motor 21, which is installed on the side of the supporting shell 11 through a motor base 13. The driving motor 21 is the power source of the grinder and can convert electrical energy into mechanical energy to provide the necessary power for the rotation of the grinding disc 34. The motor base 13 serves as an installation platform for the driving motor 21, which not only provides a stable support, but also ensures the stability and safety of the motor during operation.

[0030] The driving motor 21 is connected to the rotating rod 31 through the transmission wheel 22 and the transmission belt 23. Through the cooperation of the transmission wheel 22 and the transmission belt 23, the driving motor 21 can efficiently and stably transmit power to the rotating rod 31, thereby driving the grinding disc 34 to rotate, thereby achieving the grinding and refinement of the pigment.

[0031] A protective shell 24 is installed at the upper end of the driving motor 21. The protective shell 24 is arranged on the outside of the transmission wheel 22 and the transmission belt 23. The protective shell 24 is a protective structure covering the outside of the transmission wheel 22 and the transmission belt 23. It is installed at the upper end of the driving motor 21 to form a closed or semi-closed space to isolate the transmission components from the external environment.

[0032] A discharge port 121 is provided on the side of the grinding base 12, and a discharge tray 35 is fixed to the upper end of the rotating rod 31. The position of the discharge tray 35 corresponds to the discharge port 121. The discharge port 121 is used to discharge the pigment particles after grinding from the inside of the grinding base 12. The discharge tray 35 assists the pigment particles to move toward the discharge port 121 through its rotation and position design, thereby promoting the discharge of the pigment.

[0033] The grinding disc 34 is provided with a plurality of leak holes 341 , which are used to allow pigment particles or fine powder to fall through the holes to a collection area below or to further processing steps after being subjected to the grinding force during the grinding process.

[0034] An adjusting bolt 322 is installed outside the limiting groove 321 , and the position of the support rod 33 can be adjusted by rotating the adjusting bolt 322 . The restraining force of the adjusting bolt 322 on the support rod 33 can be changed by rotating the adjusting bolt 322 , thereby achieving fine adjustment of the position of the support rod 33 .

[0035] As an embodiment of the utility model: when cleaning the plastic masterbatch pigment grinder, first inject cleaning liquid into the grinding barrel 32. According to the cleaning requirements, clean water, special cleaning agent or mixed solution can be selected as the cleaning liquid. Slowly inject an appropriate amount of cleaning liquid into the grinding barrel 32 until the liquid covers the entire grinding assembly 3, including the grinding disc 34, the grinding roller 332 and the inner wall of the grinding barrel 32 and other key parts. Start the drive motor 21. The rotating grinding disc 34 and the grinding roller 332 will flush and peel off the pigment particles attached to their surfaces under the action of the cleaning liquid. At the same time, the cleaning liquid will also penetrate into the bottom of the grinding disc 34 through the leakage hole 341 on the grinding disc 34, and further clean the hard-to-reach corners and gaps. After the cleaning is completed, turn off the drive motor 21, and wait for the cleaning liquid in the grinding barrel 32 to be discharged through the drain port; thereby completing the cleaning of the plastic masterbatch pigment grinder.
