Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ink production equipment, and particularly relates to an energy-curable ink grinding and mixing device with proportion regulation. BACKGROUND

[0002] Ultraviolet light curing (UV) ink refers to an ink that is film-formed and dried under ultraviolet light irradiation by using ultraviolet light of different wavelengths and energy. By using different ultraviolet light spectrums, different energy can be generated, and monomers in different ink binders can be polymerized into polymers, so that the color film of the UV ink has good mechanical and chemical properties. However, in the production process of the energy-curable ink, grinding and mixing are key links that determine the quality of the energy-curable ink. At present, the energy-curable ink production generally adopts a "segmented independent control" mode:

[0003] Grinding process: the pigment agglomerates are broken by a double-roller grinding machine, and the roller spacing is preset and fixed by manual experience;

[0004] Mixing process: the resin, solvent and additive are mixed in a stirring tank, and the stirring speed is operated according to a fixed time sequence program.

[0005] The mode has the following systematic defects:

[0006] (1) Contradiction between grinding accuracy and raw material adaptability

[0007] The fixed roller spacing cannot adapt to the viscosity difference of different batches of raw materials (such as carbon black is more difficult to grind than phthalocyanine blue), resulting in over-grinding and insufficient grinding.

[0008] (2) Disconnection between mixing process and grinding result

[0009] The mixing parameters do not respond to the change in grinding fineness in real time, causing secondary quality problems:

[0010] When the grinding is insufficient, high-speed stirring causes secondary agglomeration of pigments;

[0011] When the grinding is excessive, low-speed stirring is difficult to wet the particles, and a coarse phenomenon occurs.

[0012] (3) Hysteresis of manual regulation and batch difference

[0013] The operator relies on regular sampling detection (such as offline measurement by a particle size instrument every 30 minutes), which causes delay in problem discovery and difference in adjustment strategies of different shifts, resulting in color difference between batches.

[0014] Therefore, corresponding improvements are made for the problem. SUMMARY
