Description

Technical Field

[0001] The utility model relates to the field of regenerated fiber forming equipment, in particular to a regenerated fiber continuous spinneret forming equipment. Background Art

[0002] Taking viscose fiber as an example, in the production process of this type of regenerated fiber, the viscose slurry needs to be fed into the screw extruder in the spinning machine, and the high temperature and high pressure environment in the screw extruder is used to dissolve the viscose slurry into viscose liquid. The viscose liquid is then fed into the spinning device, ejected through the spinneret, stretched and cooled to form continuous viscose fibers.

[0003] To prevent clogging of the spinneret holes, the viscose liquid needs to be filtered. Therefore, a filter plate can be installed above the spinneret to filter the viscose liquid. The filter plate has a flat structure. During the production process, filtered impurities accumulate on the filter plate, causing partial blockage of the filter plate, affecting the permeability of the viscose liquid and causing insufficient liquid supply. Frequent removal of the filter plate for maintenance affects the continuous spinning efficiency of the regenerated fiber and needs to be improved. Utility Model Content

[0014] The following combination Figure 1 The technical solution of the present utility model is further illustrated by specific embodiments.

[0015] like Figure 1 The regenerated fiber continuous spinning and forming equipment shown includes: a spinning box 1, a filtering mechanism 2, a cooler 3 and a spinneret 5. The cooler 3 is arranged below the spinning box 1. The bottom of the spinning box 1 is provided with a first flange 11. In this embodiment, the top of the cooler 3 is provided with a second flange 31. The first flange 11 and the second flange 31 are fixed by screws 4. The assembly is convenient, the structure is firm, and it can be disassembled for maintenance.

[0016] An annular groove is concavely provided at the bottom of the inner hole of the first flange 11 , and the spinneret 5 is concentrically arranged in the annular groove. The second flange 31 is used to limit the bottom edge of the spinneret 5 to ensure the structural stability of the spinneret 5 .

[0017] A third flange 12 is provided on the top of the spinning box 1. An external booster pump or an output pipe of an extruder that provides viscose liquid is connected to the third flange 12. The viscose liquid is fed into the spinning box 1, filtered, and then spinned through the spinneret 5. The spinneret 5 is densely covered with spinneret holes 51, which can simultaneously spin hundreds of fibers, achieving high production efficiency.

[0018] In this embodiment, the filtering mechanism 2 includes a first filter ring 21, a first filter cartridge 22, a second filter ring 23, a second filter cartridge 24 and a conical filter cover 25.
