AI Technical Summary
In the polyester spinning process, existing technologies have failed to effectively remove the short fibers generated during spinning, resulting in defects in the yarn, causing substandard product quality and waste of raw materials, while also increasing the labor intensity of operators.
A device for cleaning yarn defects in polyester spinning was designed. It adopts a dynamic cleaning device, which uses a 5mm protrusion on a cylindrical roller to collide with a connecting rod to drive the machine parts and springs to move back and forth, thereby removing short fibers accumulated between the roller and the machine parts.
It effectively removes short fibers, improves yarn product quality, reduces raw material waste, lowers labor intensity for workers, and increases production efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of polyester spinning technology, specifically to a device for cleaning yarn defects in polyester spinning. Background Technology
[0002] Polyester yarn refers to yarn spun from polyester. Polyester is a type of fiber made from polymers through spinning, often referring to fibers produced from polyethylene terephthalate (PET). In my country, it is commonly known as polyester fiber.
[0003] In polyester spinning, drawing frames are used. Some of the lower rollers in the feed section of existing drawing frames lack cleaning devices, while others have them but are statically attached to the surface of the lower rollers. During the spinning process, short fibers are generated. As the amount of short fibers accumulates, or when the raw materials are of poor quality or there are problems with the production process, the amount of short fibers will be excessive. If the short fibers are not removed, they will be carried into the yarn, eventually forming defects in the yarn and causing waste of raw materials.
[0004] During the production process, short fibers may appear on the spinning cylindrical roller 1 and be carried into the yarn, ultimately resulting in a series of problems such as defects in the yarn, substandard product quality, increased raw material waste, and increased labor intensity for operators. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a device for cleaning yarn defects in polyester spinning, which solves the technical problems mentioned in the background section.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for cleaning yarn defects in polyester spinning, comprising a main body, a cylindrical roller, and a second component. The cylindrical roller is installed inside the main body, and the second component is movably installed inside the main body on the side near the cylindrical roller. A first component is installed on the side of the second component near the cylindrical roller. A connecting rod is installed on the first and second components, and a spring is installed on the second component, with one end of the spring connected to the connecting rod.
[0007] Preferably, a 5mm protrusion is installed on the cylindrical roller, and the position of the 5mm protrusion corresponds to that of the connecting rod. Beneficial effects
[0008] This invention provides a device for cleaning yarn defects in polyester yarn. The device employs a dynamic cleaning mechanism that removes short fibers as they accumulate, preventing them from being carried into the yarn and causing defects, material waste, and increased labor intensity. This improves yarn quality, reduces material waste caused by yarn defects, increases production efficiency, and reduces worker workload. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the cylindrical roller structure of the device for cleaning yarn defects in polyester spinning according to the present invention.
[0010] In the diagram: 1. Cylindrical roller; 2. First component; 3. Second component; 4. Spring; 5. Connecting rod; 6. 5mm protruding nail. Detailed Implementation
[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Please see Figure 1 This utility model provides a technical solution: a device for cleaning yarn defects in polyester spinning, including a main body, a cylindrical roller 1, and a second component 3. The cylindrical roller 1 is installed inside the main body, and the second component 3 is movably installed inside the main body on one side near the cylindrical roller 1. A first component 2 is installed on the side of the second component 3 near the cylindrical roller 1. A connecting rod 5 is installed on the first component 2 and the second component 3. A spring 4 is installed on the second component 3, and one end of the spring 4 is connected to the connecting rod 5.
[0013] The cylindrical roller rotates as the drawing frame runs. When the 5mm protrusion on the cylindrical roller collides with the connecting rod, it will cause part 1, which is fixed to the connecting rod, to move back and forth. At this time, the spring connected to the connecting rod and part 1 will also move back and forth. As part 1 moves back and forth, the short fibers accumulated between the cylindrical roller and part 1 are removed, achieving the final defect removal effect.
[0014] In this embodiment, the cylindrical roller 1 is further configured to have a 5mm protruding nail 6 installed on it, and the 5mm protruding nail 6 corresponds to the position of the connecting rod 5.
[0015] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.
[0016] Example: The cylindrical roller rotates as the drawing frame runs. When the 5mm protrusion on the cylindrical roller collides with the connecting rod, it will move the component 1, which is fixed to the connecting rod, and cause it to shift back and forth. At this time, the spring connected to the connecting rod and component 1 will also shift back and forth. As component 1 moves back and forth, the short fibers accumulated between the cylindrical roller and component 1 are removed, achieving the final defect removal effect.
[0017] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
