AI Technical Summary
Existing plastic dye particles are prone to unevenness during the mixing process, and prolonged mixing time can lead to particle wear and static electricity generation.

The ratio of the inner and outer surface diameters is 1/3 to 1/2, and the width of the serration groove is not less than 0.04 of the circumference. It imitates the serrated carbon nanotube structure to improve the uniformity of mixing and provide electrostatic shielding.

Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of plastic colorants, and particularly relates to a plastic dye particle tube. BACKGROUND
[0002] Plastic dye plastic colorants include color masterbatch, color sand, color paste, color powder and the like, among which color masterbatch and color sand are most widely used. Common forms of the color masterbatch are spherical and cylindrical. There are the following technical problems: during mixing, due to the certain difference in density between main material particles (such as ABS plastic cylindrical particles) and dye particles, and the main material particles and the dye particles are both cylindrical particles with basically the same form, the problem of uneven mixing is prone to occur. Prolonging the mixing time is one of the solutions to solve the uniformity of mixing. However, prolonging the mixing time will cause particle abrasion to generate powder and will make the particles carry static electricity. CONTENT OF THE UTILITY MODEL

[0025] Please refer to Figs. 1-2 The plastic dye particle tube disclosed in the present application has a circular tube structure, and the diameter of the circular tube is between 2-3mm and the length is between 3-5mm. During implementation, the specific size can be flexibly adjusted according to different molding processes, such as the diameter and length size between 2-3mm for injection molding process, the diameter and length size between 2-5mm for blow molding process, etc.
[0026] The tube structure of the plastic dye particle tube includes an outer surface 1 and an inner surface 2. The outer surface 1 is provided with an outer sawtooth 3, and the inner surface 2 is provided with an inner sawtooth 4. The outer surface 1 is provided with an outer sawtooth 3. The inner surface 2 is provided with an inner sawtooth 4.

[0027] In order to facilitate the influx of small particle master particles or powders, the end of the outer sawtooth 3 and the end of the inner sawtooth 4 are both provided with a chamfer structure 5.
[0028] In order to ensure the carrying capacity of the main material, the diameter d of the inner surface 2 is 1 / 3-1 / 2 of the diameter D of the outer surface 1, and the width of the circular arc groove of the outer sawtooth 3 and the inner sawtooth 4 is not less than 0.04 of the circumference of the outer surface 1 and the inner surface 2 respectively.

Thus, the uniformity between the dye particles and the main material particles can be improved. At the same time, due to the electrostatic shielding effect of the outer surface 1 and the inner surface 2 of the particle tube, the electric field in the particle tube cavity is close to 0, so that the plastic dye particle tube disclosed in the application can form a stable carrier.
