Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermoplastic material coloring, in particular to an elastic thermoplastic material coloring device used for a meridian tapping device. Background Art
[0002] Coloring thermoplastic materials usually involves the use of dyes, pigments or masterbatches to change the color of thermoplastics. These materials can be colored during the plastic manufacturing process or after manufacturing through secondary processing (such as injection molding, extrusion or blow molding).
[0003] When coloring the thermoplastic material on the meridian beater, it is often done by coloring the masterbatch and then using injection molding with a screw extruder. In this process, uniform coloring of the thermoplastic material is an important guarantee for ensuring the product quality of the thermoplastic material of the meridian beater. When injecting the masterbatch raw materials and pigments, the separate injection will cause the pigment and masterbatch to be separated into upper and lower layers. After that, the mixing effect is relatively poor and uneven mixing is likely to occur. In addition, there is a lot of gas mixed in during the mixing process, which will also cause internal bubbles and other defects in the finished elastic thermoplastic material of the meridian beater.

[0019] Support columns 13 are fixed to the periphery of the bottom of the mixing and coloring box 1 , and a screw extruder 9 is fixed between the support columns 13 . The feed inlet at the upper end of the screw extruder 9 is aligned with the discharge outlet at the bottom of the mixing and coloring box 1 .
[0020] A fixing frame 6 is fixed on the inner wall of the mixing and coloring box 1 and located above the rotating end plate 5, a cylinder 61 is fixed on the fixing frame 6, and a positioning block 62 is fixed to the output end of the cylinder 61, a positioning hole 54 is opened on the rotating end plate 5 and at a position corresponding to the positioning block 62, a ball 64 is installed at the bottom of the positioning block 62, and the bottom of the ball 64 is against the upper end of the rotating end plate 5.

At this time, the stirring motor 14 is used to drive the stirring rod 11 to rotate forwardly, which can drive the rotating end plate 5 and the shielding sleeve 51 to rotate synchronously. When the connecting hole 52 on the shielding sleeve 51 is aligned with the injection port 4, the masterbatch raw materials or pigments can be discharged into the aligned position, thereby ensuring intermittent injection of the two, ensuring the uniformity of the injection process, and facilitating subsequent uniform stirring.
