Description

Technical Field

[0001] This invention relates to the field of hollow fiber membrane spinning technology, and more specifically, to a magnetic transmission structure and method for hollow fiber membrane spinning. Background Technology

[0002] Hollow fiber membrane spinning typically involves using specific equipment and processes to form hollow fiber structures from raw materials such as polymers under certain conditions. Specifically, the polymer solution or melt is extruded from a spinneret, and the extruded material rapidly solidifies to form fibers with a hollow structure. The transmission system plays a crucial role in the spinning process, controlling the spinning speed, ensuring stability, and enabling automation. Current transmission systems include components such as motors, reducers, drive shafts, and synchronous belts. The entire system relies on multiple synchronous belts for transmission. However, synchronous belt transmission suffers from several drawbacks. First, the transmitted power is unstable, affecting the quality of the work. Second, synchronous belts are prone to breakage and splintering under prolonged use, and they easily loosen, requiring frequent manual adjustments during use. Replacement after breakage is difficult, time-consuming, labor-intensive, and reduces efficiency and increases operating costs. Furthermore, the existing structure's limiting combs cannot be adjusted to different heights according to actual usage requirements, limiting its application and resulting in poor quality.

[0003] Therefore, those skilled in the art are dedicated to providing a magnetic transmission structure and method for hollow fiber membrane spinning that can effectively solve the above-mentioned technical problems. Summary of the Invention

[0004] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a hollow fiber membrane spinning magnetic transmission structure and method that can effectively solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention provides a magnetic transmission structure for hollow fiber membrane spinning, including a frame, a plurality of first guide units arranged along the length of the frame, each first guide unit having a first combing unit that works with it and is connected to the frame, the front end of each first guide unit being connected to the output end of a drive mechanism through a non-contact transmission unit, the drive mechanism being arranged on the frame;

[0006] A second guide unit and a second combing unit are provided between each two adjacent first guide units. Each second guide unit and second combing unit is respectively provided on each of the sliding seats. Each sliding seat is slidably connected to the frame. A plurality of lifting adjustment mechanisms are provided on the frame. Each lifting adjustment mechanism is respectively provided in correspondence with each of the sliding seats and is used to drive each sliding seat to move along the vertical direction of the frame.

[0007] Furthermore, the non-contact transmission unit includes several driven magnetic couplings, each driven magnetic coupling being connected to the front half of each of the first guide units. The output end of the drive mechanism is connected to the drive shaft. The drive shaft is rotatably mounted on the frame. Several drive magnetic couplings are mounted on the drive shaft. Each drive magnetic coupling is correspondingly mounted to each driven magnetic coupling and they cooperate with each other.

[0008] Furthermore, each of the first guide units includes a driven drive shaft, the rear half of each driven rotating shaft is rotatably connected to the frame, the front half of each driven rotating shaft rotatably passes through each bearing seat and is magnetically connected to the driven magnetic coupling, each bearing seat is simultaneously mounted on a bearing fixing bracket, and the bearing fixing bracket is detachably mounted on the frame.

[0009] A first guide wheel is fitted onto the driven rotating shaft, and the first combing unit works in conjunction with the first guide wheel.

[0010] Furthermore, the first combing unit includes a positioning frame disposed below the first guide wheel and detachably connected to the frame. The positioning frame is provided with a plurality of first limiting comb teeth, and two adjacent first limiting comb teeth are spaced apart.

[0011] The first limiting comb tooth includes a positioning section. The lower end of the positioning section is fixedly connected to the positioning frame. The upper end of the positioning section is connected to the inner end of the extension section. The extension section is inclined with the inner side lower than the outer side. The outer end of the extension section is connected to the lower end of the combing section. The positioning section, the extension section, and the combing section are integrally formed.

[0012] Furthermore, the drive mechanism includes a drive motor, which is connected to the frame via a motor bracket. The output end of the drive motor is provided with a drive pulley, which is connected to a driven pulley via a transmission belt. The frame has an opening for the transmission belt to pass through. The driven pulley is sleeved on the drive shaft, which is mounted on the frame via several vertical bearings. The drive shaft is located below the driven shaft.

[0013] Furthermore, the second guide unit includes a second guide wheel, the diameter of which is smaller than the diameter of the first guide wheel;

[0014] The second combing unit is located above the second guide wheel. The second guide wheel includes a positioning rod connected to the sliding seat. The positioning rod is connected to the inner end of a plurality of second limiting comb teeth. Each second limiting comb tooth has a guide head at its outer end. Two adjacent second limiting comb teeth are spaced apart. Each second limiting comb tooth is inclined with the outer side higher than the inner side.

[0015] Furthermore, the lifting and adjusting mechanism includes a driving sprocket and a driven sprocket respectively rotatably disposed on the upper half and lower half of the frame. The driving sprocket and the driven sprocket are connected by a transmission chain. The frame is provided with a plurality of adjusting motors. The output end of each adjusting motor is connected to each driving sprocket. The rear end of each sliding seat is connected to each transmission chain. Tracks are provided on both sides of each driving sprocket. The rear end of each sliding seat is slidably connected to each track.

[0016] Furthermore, the frame includes a base frame, the lower end of which is provided with a plurality of support legs. A plurality of front columns and rear columns are provided on the base frame. Each of the front columns and each of the rear columns is connected by a crossbar. A mounting platform is provided on the crossbar.

[0017] Furthermore, the track is connected to both the rear column and the base frame, and the driving sprocket and the driven sprocket are respectively mounted on the frame via various mounting components.

[0018] The method of using the magnetic drive structure in hollow fiber membrane spinning involves starting a drive motor mounted on a motor bracket to rotate the active drive wheel. The rotating active drive wheel then drives a non-contact transmission unit. This non-contact transmission unit replaces synchronous belt drive, resulting in more stable output force and improved production efficiency. The specific operation of the non-contact transmission unit is as follows: the rotating active drive wheel drives the driven drive wheel via a transmission belt. As the driven drive wheel rotates, its active drive shaft follows suit, driving the active magnetic coupling. The rotation of the active magnetic coupling then drives the magnetically connected driven magnetic coupling to rotate. When the driven magnetic coupling rotates with the active magnetic coupling, the driven magnetic coupling does not contact the active magnetic coupling. Under the action of magnetism, the rotating driven magnetic coupling drives the driven transmission shaft to rotate. As the driven transmission shaft rotates, it drives the first guide wheel sleeved on the driven transmission shaft to rotate, thereby driving and guiding the hollow fiber membrane spinning through the first guide wheel. This facilitates the control of the active transmission shaft to drive the rotation of multiple active and driven magnetic couplings. By adjusting the motor to drive the active sprocket to rotate, the rotating active sprocket drives the transmission chain to move. The moving transmission chain adjusts the sliding seat up and down, and the set track guides the sliding seat, improving stability.

[0019] The beneficial effects of this invention are as follows: On one hand, the invention uses a drive motor to drive a driving transmission wheel, which in turn drives a driven transmission wheel via a transmission belt. As the driven transmission wheel rotates, its driving shaft follows suit. This rotating driving shaft drives a driving magnetic coupling, which in turn drives a magnetically connected driven magnetic coupling. When the driven magnetic coupling and the driving magnetic coupling rotate, the rotating driven magnetic coupling drives the driven transmission shaft to rotate as well. This rotation of the driven transmission shaft drives the first guide wheel mounted on it to rotate, thus guiding the hollow fiber membrane spinning process. This facilitates controlling the driving shaft to drive multiple driving magnetic couplings and driven magnetic couplings. The shaft rotates, thus replacing the traditional synchronous belt drive. This effectively improves transmission stability, thereby enhancing work quality. Furthermore, the combination of the active and driven magnetic couplings effectively solves the problems of breakage and splintering inherent in traditional synchronous belts, reducing downtime for maintenance and lowering operating costs and operator workload. Additionally, adjusting the motor drives the active sprocket, which in turn moves the transmission chain, allowing for vertical adjustment of the sliding seat. This improves applicability, and the guide rail further enhances overall operational stability. It also offers advantages such as increased production efficiency, simple structure, ease of operation, low manufacturing cost, and durability. Attached Figure Description
