Description

TECHNICAL FIELD

[0001] The utility model relates to the field of spinning, especially to the field of regenerated fiber processing for environmental protection consumption, and specifically relates to a single spindle jet type recycling fiber opening equipment. BACKGROUND

[0002] With the global emphasis on sustainable development, yarns made from recyclable regenerated fibers not only help to solve the current resource and environmental problems, but also provide a new path for the sustainable development of the textile industry. The opening equipment is an advanced device specially designed for processing pre-consumer recycled fibers. The head end of the pre-consumer roving waste is sucked into the appropriate air suction port, combined with the unwinding action of the high-speed spindle, and the compressed air flow is used to open and mix the roving strip entering the air suction port, aiming to improve the quality and uniformity of the regenerated fiber, while reducing the mechanical damage to the fiber.

[0003] Such equipment can be widely used in the pre-consumer recycled fiber pretreatment stage of the textile industry, especially for those enterprises committed to sustainable development and circular economy. It not only improves the quality of regenerated fibers, but also promotes the effective use of resources, reduces the dependence on raw materials, and promotes the transformation of the textile industry to a more environmentally friendly direction.

[0004] Traditional pre-consumer roving waste treatment equipment generally uses mechanical impact and carding opening. This method has many shortcomings: mechanical impact can cause fiber breakage or excessive wear, causing fiber damage, which reduces the length and strength of the fiber, which has a negative impact on the quality of regenerated fibers, especially for fine textiles; low efficiency, mechanical methods cannot efficiently process large amounts of waste, as they rely on physical contact to disperse and loosen the material, which results in slow and uneven processing speed; high energy consumption, as large forces are needed for impact and carding operations, such equipment usually consumes a lot of energy, increasing production costs and having adverse effects on the environment; complex maintenance, mechanical parts are prone to wear and tear, requiring regular inspection and replacement of parts, increasing the difficulty and frequency of equipment maintenance, as well as operating costs; poor adaptability, different fiber types and structures require specific processing methods, while mechanical impact and carding equipment do not have enough flexibility to adapt to various types of waste. SUMMARY

[0005] This invention addresses the shortcomings of existing technologies by providing a single-spindle jet-type circulating reprocessing fiber opening device. It utilizes compressed air nozzles to generate a powerful airflow, which physically breaks down fiber bundles into individual fibers or smaller clusters. Compared to traditional mechanical opening methods, jet-type opening can achieve better and more efficient opening results without damaging the fiber structure. By reducing fiber entanglement and clumping, the resulting fibers are softer and easier to spin.

[0006] This utility model is achieved through the following technical solution: a single-spindle jet-type circulating reprocessing fiber opening device, including a roving tube with pre-consumption roving, a yarn collecting box located on one side of the roving tube, and a suction pipe located between the yarn collecting box and the roving tube. The suction pipe is connected to an inclined jet pipe that sprays high-speed airflow into the yarn collecting box, and the jet pipe is provided with an airflow nozzle that sprays airflow into the suction pipe.

[0007] In use, the roving head of the waste roving from the roving tube is placed into the suction port of the suction pipe. At the same time, a high-speed airflow is introduced into the suction pipe through the jet nozzle, thereby drawing the waste roving into the suction pipe. Compressed air from the airflow nozzle is directly sprayed onto the roving, opening it into small fiber clusters or single fibers. The size of the airflow from the nozzle can be adjusted according to the different fiber composition and structure of the roving, thereby realizing the use of compressed air nozzles to generate a strong airflow, which decomposes the fiber bundle into single fibers or smaller clusters through physical action. Compared with traditional mechanical opening methods, jet opening can achieve better and more efficient opening effect without damaging the fiber structure. Because it reduces the entanglement and clumping between fibers, the final fiber is softer and easier to spin.

[0008] Preferably, a top cover is connected to the top surface of the yarn collecting box, and an opening for fibers to enter is provided on the side of the top cover near the yarn collecting box.

It also facilitates the active unwinding of the roving from the roving tube and into the air intake by the rotation of the spindle and the suction force.

[0014] As preferred, the several exhaust pipes correspond to the same total yarn box.

[0015] As preferred, the yarn collecting box is provided with a guide plate which is inclined to the feeding opening.

[0016] The roving head end of the roving waste before consumption is placed into the suction port of the suction pipe, and the high-speed airflow enters into the suction pipe through the jet pipe, so that the roving before consumption is driven into the suction pipe, the compressed air which is sprayed by the airflow nozzle directly sprays the roving body, and the roving is opened into fiber clusters or single fiber, the size of the nozzle airflow can be adjusted according to the different fiber components and structures of the roving, so that the powerful airflow is generated by the compressed air nozzle, the fiber bundle is decomposed into single fiber or smaller clusters by the physical action, compared with the traditional mechanical opening method, the air-jet opening can realize better and more efficient opening effect without damaging the fiber structure, the obtained fiber is more soft and easy to spin due to the reduction of the winding and clustering phenomenon between the fibers.
