Abstract
Description
Technical Field
[0001] This utility model relates to the field of melt spinning equipment technology, and in particular to the melt spinning structure of chemical fiber polyester composite yarn. Background Technology
[0002] Melt spinning equipment is a key piece of equipment used to process polymer melt into fibers. It is widely used in the production of synthetic fibers such as polyester, nylon, and polypropylene. In some existing melt spinning equipment, friction wheels are typically used to rub the fibers to stabilize the fiber tension. The friction wheels are usually fixed in place. During the spinning process, the friction wheels are in continuous contact with the fibers and apply tension. Long-term use will cause wear on the surface of the friction wheels, affecting the stability of its friction force and thus affecting the quality of spinning.
[0003] In summary, this application proposes a melt-spinning structure for chemical fiber polyester composite yarn to solve the aforementioned problems. Utility Model Content
[0004] The purpose of this invention is to provide a melt spinning structure for polyester composite yarn, which can solve the problem that in some existing melt spinning devices, friction wheels are usually used to rub the yarn to stabilize the fiber tension. Usually, the friction wheels are fixed in place, and they are in continuous contact with the fiber and apply tension during the spinning process. Long-term use will cause wear on the surface of the friction wheel, affecting the stability of its friction force, and thus affecting the quality of spinning.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a melt spinning structure for polyester composite yarn, comprising a mounting frame, a stretching assembly, and a pressing assembly. A transmission roller is rotatably mounted on the mounting frame. The stretching assembly is located inside the mounting frame and includes a sliding seat, a drive gear, a servo motor, an arc-shaped opening, and an arc-shaped toothed plate. Sliding seats are fixedly connected to both the front and rear sides of the mounting frame. Drive gears are fixedly connected to the outer walls of both sets of sliding seats. Arc-shaped toothed plates are fixedly connected to the inner walls of both the front and rear sides of the mounting frame. The drive gear meshes with the arc-shaped toothed plate. The pressing assembly is located on one side of the stretching assembly.
[0006] Preferably, the mounting frame has arc-shaped openings on both the front and rear sides, and the sliding seats are slidably mounted on the arc-shaped openings. A servo motor is fixedly connected to one set of sliding seats, and the output shaft of the servo motor is connected to one set of sliding seats. Through the coordinated use of the sliding seats, drive gears, servo motors, arc-shaped openings, and arc-shaped toothed plates, the spinning process can be stretched. Stretching helps to make the fibers thinner and longer, and the fineness of the fibers can be precisely adjusted, thereby improving the uniformity and quality of the product. Furthermore, the drive gears, servo motors, and arc-shaped toothed plates can regulate the tension of the stretched spinning process. Appropriate tension adjustment can effectively prevent the fibers from breaking or fraying due to excessive tension during the stretching process, ensuring the integrity and quality of the fibers, thereby improving the quality of the fibers and reducing the generation of waste.
[0007] Preferably, the front side of the mounting frame is integrally formed with a protractor scale, and a set of sliding seats has arrows, which facilitates the use of the tensioning component and improves the accuracy of the tensioning component.
[0008] Preferably, threading rollers are rotatably mounted on the inner walls of the front and rear sides of the mounting frame. Multiple threading grooves are provided on the threading rollers, which facilitates the use of the auxiliary pressing assembly.
[0009] Preferably, the pressing assembly includes a hollow connecting block, a fixing rod, a pressing block, a spring damper, and a rectangular block. Hollow connecting blocks are fixedly connected to the inner walls of the front and rear sides of the mounting frame. Multiple sets of pressing blocks are fixedly connected to the outer wall of the fixing rod. Rectangular blocks are fixedly connected to both ends of the fixing rod, and a spring damper is fixedly connected to the top of each rectangular block. One end of the spring damper is connected to the inner top of the hollow connecting block. Through the coordinated use of the hollow connecting block, fixing rod, pressing block, spring damper, and rectangular block, the spinning process can be pressed. Through uniform compression, the yarn maintains a consistent diameter and shape after stretching, reducing uneven thickness caused by uneven yarn shape during stretching. Ensuring yarn uniformity is crucial for the appearance and quality of textiles. In conjunction with the stretching assembly, it helps the fiber maintain a stable shape during the setting process, preventing the yarn from loosening or deforming during subsequent processing.
[0010] Preferably, the center point of the pressure block and the threading groove are on a straight line, and a gap is formed between the pressure block and the threading groove. The gap is designed to allow the spinning thread to pass through. The top of the mounting frame is provided with a threading opening, which facilitates the threading of the spinning thread.

The setting of drive gear, servo motor and arc-shaped toothed plate can play the role of adjusting the tension of the stretched spinning. Appropriate tension adjustment can effectively prevent the fiber from breaking or filament breaking due to excessive tension during the stretching process, ensuring the integrity and quality of the fiber, thereby improving the quality of the fiber and reducing the generation of waste.
[0013] (2) The melt spinning structure of the chemical fiber polyester composite yarn, through the combined use of hollow connecting block, fixing rod, pressure block, spring damper and rectangular block, can perform yarn pressing work on the spinning.
