Spinning masterbatch production equipment

Abstract

The invention discloses spinning masterbatch production equipment. The spinning masterbatch production equipment comprises a double-screw extruder with a feeding opening and a discharging opening, wherein the feeding opening is connected with a dye adding device; the discharging opening is connected with a forming mold; the dye adding device comprises a storage funnel; a feeding rotary table is arranged at the bottom of the storage funnel and comprises a circular rotary table body and disturbance teeth which are distributed in a radial manner from the central part of the rotary table body to the outer side in the radial direction; discharging holes are formed in the rotary table body and positioned among the circumferentially adjacent disturbance teeth; the forming mold comprises a mold head with a forming hole in a head part; a cavity which communicates with the forming hole is formed in the mold head; a conical groove is formed in the cavity and corresponds to a conical position of the head part; an external heating device is arranged on the outside of the mold head; and a heating mandrel is arranged in the center of the cavity. By the spinning masterbatch production equipment, materials can be discharged from the discharging holes smoothly, blockage can be avoided, the inside and the outside of the forming mold are heated, and therefore, uneven heating of raw materials can be avoided.

Description

technical field [0001] The invention relates to production equipment for spinning color masterbatch. Background technique [0002] In-fiber dyeing has become popular in recent years. Compared with external dyeing of yarn or fabric, the process of in-fiber dyeing has significant environmental protection and economic value in terms of waste water, gas and energy. At present, the general method of in-fiber coloring is: in the spinning chip or melt stage, dyeing with masterbatches, for each fiber color, a traditional color masterbatch is equipped to produce colored fibers, so the color masterbatch Quality has a great influence on the final fiber product. [0003] However, in the process of producing color masterbatch, on the one hand, during the feeding process of raw materials, the feeding speed is not easy to control, and it is easy to block. On the other hand, the die head of the twin-screw extruder adopts an external heating method, and the heating is uneven. The above tw...
