S4: Shut down the plastic color mixing machine, and discharge the mixture of abrasive particles and cleaning liquid.

The following further describes the cleaning method of the plastic color mixing machine provided by the embodiment of the present invention. In the cleaning method of the plastic color mixing machine provided by the embodiment of the present invention, the abrasive particles are poured into the material cavity of the plastic color mixing machine, and the cleaning liquid is poured into the material cavity Inside, the cleaning liquid and the abrasive particles are mixed evenly, so that the mixture of the cleaning liquid and the abrasive particles constitutes the raw material for grinding and cleaning the material cavity. Then, when the cleaning liquid and abrasive particles are evenly mixed in the material cavity of the plastic color mixing machine, the plastic color mixing machine can be started, then the mixture of cleaning liquid and abrasive particles can be driven by the blades in the material cavity relative to the material cavity. The inner wall rotates, so that the toner attached to the inner wall of the material cavity will be separated from the inner wall of the material cavity under the scraping and grinding of the abrasive particles, so that the automatic cleaning of the inner wall of the material cavity is realized. After it is completely separated from the inner wall of the material cavity, the mixture of abrasive particles and cleaning liquid can be discharged to complete the cleaning process of the inner wall of the material cavity. In this way, the cleaning method of the plastic color mixer provided by the embodiment of the present invention realizes the automatic removal of the toner adhering to the inner wall of the material cavity through the grinding and scouring action of the mixture of the abrasive particles and the cleaning liquid on the inner wall of the material cavity, which significantly improves the efficiency of cleaning. The removal efficiency of the toner is improved, and the labor intensity is reduced.

In an embodiment of the present invention, in step S1, the abrasive particles poured into the material cavity do not pass through the paddles in the material cavity. Specifically, by controlling the pouring amount of the abrasive mechanism to the extent that it does not pass the paddle, it can ensure that the number of abrasive particles in the material cavity is kept within a reasonable range. On the other hand, the driving force generated by the paddle can drive the abrasive particles to flow relative to the inner wall of the material cavity.

In an embodiment of the present invention, step S2 includes the following steps:

S21: Divide the cleaning solution into N parts, and make the pouring volume of each part of the cleaning solution can satisfy the surface wetting of the abrasive particles; S22: Pour each part of the cleaning solution into the material cavity in sequence and mix with the abrasive particles uniformly until N parts of the cleaning solution are poured out.

Further, 1≤N≤5. The specific value of N depends on the distribution area of the toner on the inner wall of the material cavity. When the distribution area of the toner attached to the inner wall of the material cavity is large, the value of N can be selected from a larger value within the above-mentioned numerical range, otherwise, a smaller value can be selected.

In an embodiment of the present invention, step S4 is specifically:

Shut down the plastic color mixing machine and observe whether there is toner residue in the material chamber. When there is no toner residue in the material chamber, discharge the mixture of abrasive particles and cleaning liquid; when there is toner residue in the material chamber, repeat step S3, Until there is no toner residue in the material cavity. Specifically, when no toner residue can be observed with the naked eye in the material cavity, it means that the toner attached to the inner wall of the material cavity has been basically removed, and the mixture of abrasive particles and cleaning liquid can be discharged at this time, and the abrasive material After the particles are discharged, they can be collected and can be reused. When the toner residue can still be observed with the naked eye, step S3 can be repeated until the toner adhered to the inner wall of the material cavity is removed.

In an embodiment of the present invention, as shown in FIG. 1 , the following steps are further included after step S4:

S5: Use high-pressure water to spray and wash the inner wall of the material cavity; specifically, by causing the high-pressure water to spray the inner wall of the material cavity, the remaining impurities on the inner wall of the material cavity can be completely removed, so that the toner removal process has thoroughness.

S6: Use a rag to wipe the inner wall of the material cavity. Specifically, after the above process is finished, the inner wall of the material cavity can be wiped clean with a flexible cloth such as a rag. In this way, the inner wall of the material cavity can be quickly dried, so that the color mixing process of the next batch can be carried out quickly. Optionally, when the inner wall of the material cavity is relatively clean after step S4 is completed, step S5 may be skipped directly, and step S6 may be performed.

In one embodiment of the present invention, the abrasive particles are cone-shaped or tetrahedral-shaped particles. Specifically, by setting the abrasive particles into a cone shape or a tetrahedron shape, the abrasive particles have sharper grinding edges and corners, so that the abrasive particles can quickly and efficiently scrape off the toner attached to the inner wall of the material cavity. net.

In one embodiment of the present invention, the abrasive particles are resin particles. Specifically, by selecting the abrasive particles as resin particles, the resin particles have a moderate hardness value and certain elastic properties, so that the resin particles can scrape off the toner on the inner wall of the material cavity while ensuring maximum guarantee. Do not scratch the inner wall of the material cavity.

In one embodiment of the present invention, the length dimension of the cubic space occupied by the unit particle of the abrasive particles is greater than or equal to 2 mm and less than or equal to 15 mm; the width dimension of the cubic space occupied by the unit particle of the abrasive particles is greater than or equal to 2 mm and less than or equal to 15 mm; The height dimension of the cubic space occupied by the unit particle of the particle is greater than or equal to 2mm and less than or equal to 15mm. By limiting the length, width, and height of the abrasive to the above-mentioned size range, it ensures that the size of the abrasive particles can adapt to the size of the material cavity of the plastic color mixing machine, and avoids that the size of the abrasive particles is too large to be driven by the paddle in the material cavity. Rotate relative to the inner wall of the material chamber. Further, the length dimension, width dimension and height dimension of the abrasive particles can be: 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm or 15mm.

Preferably, the length, width and height of the abrasive particles are all greater than or equal to 3 mm and less than or equal to 10 mm. Specifically, the length, width and height of the abrasive particles can be: 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm. In this way, while ensuring that the abrasive particles can move smoothly relative to the inner wall of the material cavity under the driving of the paddle in the material cavity, it is also possible to avoid the phenomenon that the size of the abrasive particles is too small and the production cost of the abrasive particles is too high.

In an embodiment of the present invention, the cleaning solution is water, alkaline cleaning solution or petroleum-based cleaning solution. Specifically, more economically, the cleaning liquid can be selected from aqueous liquid. By selecting the cleaning liquid as an alkaline cleaning liquid, the oily toner attached to the inner wall of the material cavity can be better removed. By selecting the cleaning liquid as a petroleum-based cleaning liquid, the cleaning liquid can also perform anti-rust treatment on the inner wall of the material cavity while washing the toner in the inner cavity, so that the inner wall of the material cavity is not easy to form rust scale.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. Inside.
