Description

Technical Field

[0001] The utility model relates to the technical field of ink preparation, in particular to a raw material mixing device for preparing photosensitive ink. Background Art

[0002] Photosensitive ink is UV-sensitive and UV-curable. It is widely used in industries such as PCBs, mobile phones, SMT, IC leads, VFD grids, watches, laptop cases, and signage. Conventional photosensitive inks are solvent-free and feature fast drying, excellent gloss, vibrant color, water resistance, solvent resistance, and abrasion resistance, as well as excellent adhesion. The raw material mixing device for photosensitive ink preparation is used to uniformly mix the raw materials required for preparing the photosensitive ink.

[0003] Common raw material mixing devices for preparing photosensitive inks generally use a motor to drive the rotation of a stirring mechanism to mix various raw materials inside a mixing kettle. However, since the motor can only drive the stirring mechanism to rotate in a circumferential direction, the raw materials at the bottom cannot be effectively stirred when stirring the ink raw materials, resulting in a slow mixing speed. Moreover, as the stirring and adding of materials are continuously carried out, residual liquid of the raw materials will adhere to the inner wall of the mixing kettle, making it impossible to obtain effective stirring, thereby reducing the uniformity of the raw material mixing and failing to meet the working requirements of the raw material mixing. Therefore, a raw material mixing device for preparing photosensitive inks is proposed. Utility Model Content
