Lyocell spinning machine forming system and spinning machine

Abstract

This utility model discloses a Lyocell spinning machine forming system and a spinning machine for circulating the spinning bath and receiving the spun yarn from below the spinning assembly. It includes an interconnected coagulation bath and a lifting and adjusting device. The lifting and adjusting device adjusts the height of the coagulation bath from the ground. The coagulation bath is conical, with a spinning inlet at the top and an outlet for partially solidified yarn at the bottom. A ring-shaped spinning bath inlet and return device are arranged around the periphery of the coagulation bath, with the inlet device located at the bottom and the return device at the top. In this Lyocell spinning machine forming system and spinning machine, the coagulation bath is lifted and moved by a top lifting device, facilitating multi-faceted operation and yarn handling by the operator. The conical shape of the coagulation bath allows the yarn to be fed out along the spinning outlet under gravity, replacing the operator's manual gathering of the yarn into a bundle, reducing the yarn handling process.

Description

Technical Field

[0001] This utility model relates to the field of spinning technology, specifically to a Lyocell spinning machine forming system and a spinning machine. Background Technology

[0002] Spinning, also known as lyocell fiber forming, is a process in the manufacture of lyocell fibers. It involves forming lyocell fibers by extruding plant fibers through the fine orifices of a spinneret after the fibers have been converted into a colloidal solution or melted into a molten state. Depending on the spinning method, it can be divided into wet spinning and dry spinning. Existing spinning machines have a fiber tow guide mechanism on one side of the spinning assembly. The bottom of the spinning assembly has a coagulation bath containing a bottom ceramic guide seat. The coagulation bath is a square tank, and a lifting device is located at the bottom. This lifting device limits operation to one side only when the spinning assembly malfunctions, making operation difficult for the operator. The inner tank of the coagulation bath has a reversing roller. The operator gathers the fibers from the spinning outlet into a bundle with their arm, then, after sorting, redirects them around the reversing roller before guiding them out through the guide roller. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a Lyocell spinning machine forming system and a spinning machine. The coagulation bath is hoisted and moved by the top lifting device, which makes it convenient for operators to operate and arrange the filament bundles from multiple sides. The coagulation bath is conical, and the filament bundles are sent out along the spinning outlet under the action of gravity, which replaces the operator's arm to gather the filament bundles into a bunch, reducing the filament bundle arrangement operation process.

[0004] To solve the above-mentioned technical problems, this utility model provides a Lyocell spinning machine forming system for circulating spinning bath liquid and receiving the spun yarn below the spinning assembly. It includes a coagulation bath and a lifting adjustment device connected to each other. The lifting adjustment device adjusts the height of the coagulation bath from the ground. The coagulation bath is conical. The top of the coagulation bath is provided with a spinning inlet, and the bottom of the coagulation bath is provided with a pre-solidified yarn outlet. The periphery of the coagulation bath is surrounded by a ring-shaped spinning bath liquid inlet device and a liquid return device. The liquid inlet device is located at the bottom of the coagulation bath, and the liquid return device is located at the top of the coagulation bath or the yarn outlet.

[0005] Furthermore, the spinning bath liquid inlet device includes an annular distribution chamber, a connected liquid inlet, and several first liquid inlet holes and second liquid inlet holes.

[0006] Furthermore, the first liquid inlet hole is not perpendicular to the coagulation bath, but rather the first liquid inlet hole and the coagulation bath are perpendicularly inclined upwards, with each first liquid inlet hole inclined upwards at an angle of 0 to 9 degrees.

[0007] Furthermore, the liquid return device includes a liquid outlet that is connected to the solidification bath and a liquid return tank that is arranged in a ring along the solidification bath.

[0008] Furthermore, each of the second liquid inlets is not perpendicular to the coagulation bath, but rather the second liquid inlets are opened at an angle perpendicular to the coagulation bath, with each second liquid inlet being at an angle of 0 to 6 degrees downwards.

[0009] Furthermore, the coagulation bath and the lifting adjustment device are interconnected via a lifting bracket.

[0010] Furthermore, the lifting adjustment device includes a power drive frame and a lifting bracket connected by a commutator. The power drive frame is equipped with a motor and a reducer that provide the driving power for lifting. The lifting bracket includes multiple transmission rods and a right-angle commutator axially connected as one unit.

[0011] This utility model also discloses a spinning machine, including the aforementioned Lyocell spinning machine forming system, with a spinning component connected above the Lyocell spinning machine forming system and a bath liquid collection tank connected below the Lyocell spinning machine forming system.

[0012] The technical advantages of this utility model are as follows: The coagulation bath of this utility model Lyocell spinning machine forming system and spinning machine is lifted and moved by the top lifting device, which makes it convenient for operators to operate and sort the filaments from multiple sides. The coagulation bath is conical, and the filaments are sent out along the spinning outlet under the action of gravity, which replaces the operator's arm to gather the filaments into a bunch, reducing the filament sorting operation process.

[0013] The first inlet hole of this coagulation bath is angled upwards at a certain angle, allowing the bath liquid to flow upwards along it. The second inlet hole is perpendicular to the coagulation bath and angled downwards. The different angles of the first and second inlets facilitate the impact of the bath liquid near the bottom of the coagulation bath to the top, allowing all the bath liquid at the top to be discharged. Therefore, the inlet and outlet holes of the coagulation bath provide omnidirectional flow and renewal of the spinning bath liquid, eliminating any dead zones in the circulation.
