Description

Technical Field

[0001] This utility model belongs to the technical field of carbon fiber production equipment, specifically relating to a rotary adjustable carbon fiber filament spinneret assembly. Background Technology

[0002] Carbon fiber, as a high-performance fiber material, is widely used in aerospace, defense, sports and leisure, medical devices, and construction. Wet spinning is a key process in carbon fiber production, involving injecting carbon fiber dope into a coagulation bath through a spinneret to form fibers. However, traditional wet spinning spinnerets have the following problems:

[0003] Existing spinnerets mostly adopt a single-layer planar layout with densely arranged spinnerets. This structural design results in a large horizontal footprint, low space utilization, and increased demand for coagulant. Furthermore, the gooseneck tube is rigidly welded, requiring complete disassembly for angle adjustment, increasing maintenance time by more than 45%. Utility Model Content

[0004] The present invention mainly addresses the technical problems existing in the prior art by providing a rotary adjustable carbon fiber filament spinning assembly.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a rotary adjustable carbon fiber dope spinneret assembly, including a spinneret assembly mounting frame, characterized in that: a horizontal frame is arranged in the middle section of the spinneret assembly mounting frame, an auxiliary frame is arranged below the horizontal frame, multiple top plates are arranged on the top of the horizontal frame, and multiple long gooseneck tube frames are arranged on the top of each top plate; a front mounting plate is arranged on the front of the auxiliary frame, and multiple short gooseneck tube frames are arranged on the front mounting plate; the long gooseneck tube frames and short gooseneck tube frames are arranged correspondingly to each other and arranged vertically and crosswise; a coagulation bath is arranged below the spinneret assembly mounting frame; multiple partitions are arranged inside the coagulation bath, and adjacent cavities are formed between each partition; each cavity respectively accommodates a set of long gooseneck tube frames and a set of short gooseneck tube frames; a bottom frame is arranged at the bottom of each cavity; and a pipe is connected to the bottom of the coagulation bath.

[0006] Preferably, the auxiliary frame is provided with base plates on both sides of its bottom, and the auxiliary frame is connected to the spinneret mounting frame through the base plates on both sides.

[0007] Preferably, the long gooseneck tube frame and the short gooseneck tube frame have the same structure, and both have a spinneret sleeved on their output ends. The long gooseneck tube frame includes a rocker seat, a limiting sleeve, a wing bolt, and a gooseneck tube. The rocker seat is set on the top plate, and the limiting sleeve is inserted into one side of the rocker seat and rotatably set inside the rocker seat. Two limiting grooves are symmetrically opened on the side of the limiting sleeve, and the limiting grooves pass through the rocker seat. The wing bolt is inserted into one end of the two limiting grooves, and the two wing bolts are located on the same vertical line.

[0008] Preferably, a plurality of first top mounting clamps are provided below the top of the spinneret mounting bracket, and a plurality of second top mounting clamps are provided at the bottom of the crossbar. The first top mounting clamps are provided above the long gooseneck tube frame, and the second top mounting clamps are provided above the short gooseneck tube frame.

[0009] Preferably, a plurality of first top mounting clamps are provided below the top of the spinneret mounting bracket, and a plurality of second top mounting clamps are provided at the bottom of the crossbar. The first top mounting clamps are provided above the long gooseneck tube frame, and the second top mounting clamps are provided above the short gooseneck tube frame.

[0010] The beneficial effects of this utility model are as follows: By arranging long and short gooseneck tube frames in a crisscross pattern, more structures for spinning can be installed in a smaller space. At the same time, by increasing the length of the coagulation bath, multiple sets of spinnerets can be accommodated, which can greatly improve the overall work efficiency. Both the long and short gooseneck tube frames are rotatably installed through a swing seat and a limiting sleeve, and the rotation angle is limited by a limiting slide groove and a wing bolt to achieve the maximum rotation angle. The spinneret design with staggered left and right arrangements changes the lateral projection area of ​​the spinning device in the coagulation bath without changing the longitudinal dimension of the coagulation bath, reducing the width of the coagulation bath, directly reducing the amount of coagulant required in the coagulation bath, and lowering production costs.

[0011] Meanwhile, a first top mounting clamp and a second top mounting clamp are respectively installed on the top to clamp the gooseneck tube after it rotates. The first bottom mounting clamp and the second bottom mounting clamp are used to clamp the gooseneck tube during use to keep it stable. At the same time, the spinneret and the gooseneck tube can be quickly installed through a flange, which facilitates subsequent replacement. Attached Figure Description
