Technical Field

[0001] This invention relates to the field of spinning equipment technology, specifically to a spinning device for Bianstone fibers and its method of use. Background Technology

[0002] Traditional Chinese medicine believes that high-quality Bian stone has the effects of calming the mind, regulating qi and blood, and unblocking meridians, making it a superior material for processing and manufacturing medical devices. Bian stone achieves some therapeutic and health-preserving effects through microcrystalline, infrared, and pulsed wavelengths. It relies on its inherent energy to stimulate the body's potential, but proper application is also crucial. Bian stone is non-radioactive and harmless to the human body.

[0003] Bianstone fiber is a new type of functional fiber material, widely used in underwear, bedding, sportswear, children's clothing, socks, etc. Existing Bianstone fiber spinning equipment is prone to fiber breakage during production, resulting in a high failure rate. At the same time, the Bianstone fiber produced by ordinary spinning equipment has a low Bianstone content and insufficient functionality.

[0019] A method for spinning Bianstone fibers, the spinning method comprising the following steps:

[0020] Step 1: First, open the foldable box cover and put the sliced ​​Bianstone polyester resin and the raw materials for spinning into the mixing box. Then, the second motor drives the stirring blade to rotate through the stirring rod and side shaft to stir the raw materials inside the mixing box. After stirring, the raw materials are transported to the inside of the extruder through the feeding pipe and connecting pipe via the conveying pump.

[0021] Step 2: The raw material is heated by a heating furnace in the extrusion box inside the extruder to form a molten raw material. Then, the first motor drives the extrusion screw to rotate through the connecting shaft, so that the molten raw material is spun from the side of the extrusion box near the spinning box inside the spinning box.

[0022] Step 3: The spinning pump inside the spinning box controls the amount of spinning.

[0023] Step 4: The Bianstone fibers are collected by winding them onto the first and second winding rollers respectively. Then, the Bianstone fibers are drawn into the cooling box for cooling. During cooling, the Bianstone fibers pass through the cooling channel inside the rotating drum, while water flows into the cooling box from the upper water inlet pipe, enters the cooling channel through the spray holes on the surface of the rotating drum, and cools the Bianstone fibers. Then, the cooled water is discharged through the lower water outlet pipe. During the cooling process, the motor drives the rotating drum to rotate, making the airflow inside the rotating drum more uniform.

[0024] Step 5: The cooled Bianstone fiber is drawn to the drawing roller, and then drawn from the drawing roller into the drawing box for stretching. The third motor provides power to the drawing roller. After stretching is completed, it is drawn from the inside of the drawing box to the take-up roller inside the second support frame for collection. The fourth motor provides power to the take-up roller.

[0025] This invention provides a spinning device for Bianstone fiber and its usage method, which has the following beneficial effects: during use, it is not easy for the fibers to break, maintaining high efficiency in the production of Bianstone fiber. At the same time, the produced Bianstone fiber contains a high amount of Bianstone, which has good effects of calming the mind, regulating qi and blood, and clearing the meridians. In addition, the production process is compact and the usage method is simple.

[0026] This application collects Bianstone fibers by winding them onto the first and second winding rollers respectively. The Bianstone fibers are then drawn into the cooling box for cooling. During cooling, the Bianstone fibers pass through the cooling channel inside the rotating cylinder, while water flows into the cooling box from the upper water inlet pipe, enters the cooling channel through the spray holes on the surface of the rotating cylinder, and cools the Bianstone fibers. The cooled water is then discharged through the lower water outlet pipe. During the cooling process, the motor drives the rotating cylinder to rotate, making the airflow inside the rotating cylinder more uniform.

[0027] In this application, the cooled Bianstone fibers are drawn to the drawing roller, and then drawn from the drawing roller into the drawing box for stretching. The third motor provides power to the drawing roller. After stretching is completed, the fibers are drawn from the drawing box into the take-up roller inside the second support frame for collection. The fourth motor provides power to the take-up roller. Attached Figure Description
