Description

Technical Field

[0001] This utility model relates to the field of nylon spinning and stretching technology, and in particular to a nylon spinning and stretching structure with a frayed edge treatment function. Background Technology

[0002] Nylon spinning stretching is a key process in nylon fiber production. It refers to the process of applying a certain tension to the nascent fiber after spinning to cause it to undergo plastic deformation along the axial direction. From the perspective of process objectives, stretching can significantly change the internal structure and properties of the fiber. First, it promotes the alignment of macromolecular chains along the fiber axis. The originally disordered molecular chains gradually tend to be parallel under the action of tension, which greatly improves the mechanical properties of the fiber, such as increasing breaking strength and reducing breaking elongation, transforming the fiber from a fragile nascent state into a material with practical strength. Second, the stretching process is accompanied by the adjustment of the crystal structure. By controlling the stretching strip, the crystallinity of the fiber can be increased or the crystal structure can be optimized, further improving the fiber's heat resistance, abrasion resistance, and dimensional stability. In the prior art, according to CN223329440U, a nylon spinning stretching structure with a frayed edge treatment function is disclosed. This structure includes a stretching base, on which a stretching assembly for stretching nylon filaments is mounted, and a heating roller mechanism for heating. The heating roller mechanism includes a moving assembly for adjusting its position. The heating roller mechanism comprises two sets of parallel heating roller bodies, each with a telescopic plate installed at both ends. An adjusting screw passes through the interior of the telescopic plate and is threadedly connected to the telescopic plate. The moving assembly includes a mounting base inserted inside the telescopic plate, and a connecting piece is provided at the connection between the mounting base and the adjusting screw. This invention can adjust the position of the heating roller according to the amount of nylon yarn, so that the nylon yarn can be completely attached to the heating roller, ensuring that the heating of the heating roller will not affect the deburring effect. However, when the device processes the burrs, the exposed yarn bundles are prone to drifting under the action of airflow, resulting in uneven burr processing and affecting fiber quality. At the same time, uneven airflow distribution will also cause yarn bundle tension fluctuations, which will lead to inconsistent fiber orientation during the stretching process and affect the mechanical property stability of the final product.

[0003] The purpose of this invention is to provide a nylon spinning and stretching structure with a frayed edge treatment function, which solves the problems of the filament bundle being easily disturbed by airflow and causing it to drift when ordinary devices in the prior art treat frayed edges, uneven frayed edge treatment, and unstable fiber orientation during the stretching process.

[0004] To achieve the above objectives, a nylon spinning and stretching structure with a burr treatment function is provided, comprising: a device body, a burr processor fixedly connected to the middle of the device body, the burr processor including an air pump, an air inlet pipe, a first air pipe, a vertical air blowing pipe, a second air pipe and an inclined air blowing pipe, an air pump fixedly connected to the top of the burr processor, the first air pipe and the second air pipe fixedly connected to the connecting end of the air pump, a vertical air blowing pipe and an inclined air blowing pipe fixedly above both ends of the burr processor respectively, one side of the vertical air blowing pipe being a discharge port and one side of the inclined air blowing pipe being a feed port; The burr processor has a processing groove inside, and a first positioning frame and a second positioning frame are fixedly connected inside the processing groove.

The side of the inclined air pipe 508 has a discharge port 506 and a feed port 509. The air pump 501 can supply air to the vertical air pipe 505 and the inclined air pipe 508 through the first air pipe 504 and the second air pipe 507 respectively, so that the vertical air pipe 505 and the inclined air pipe 508 can blow away the burrs on the surface of the nylon filament bundle from two directions. The vertical air pipe 505 and the inclined air pipe 508 can form an air curtain, which can effectively block external airflow interference and ensure the stability of the burr removal process. The airflow direction of the inclined air pipe 508 is at a 30° angle to the filament bundle running direction, which can effectively peel off the loose fuzz on the fiber surface. The burr remover 5 has a processing groove 503 inside. A first positioning frame 6 and a second positioning frame 601 are fixedly connected inside the processing groove 503. Positioning rollers 602 are connected to the first positioning frame 6 and the second positioning frame 601. A heating burr removal device 603 is fixedly connected to the middle of the processing groove 503. The heating burr removal device 603 has a groove inside, and a heating channel 605 is fixedly connected inside the groove. A heating tube 606 is laid inside the heating channel 605. The heating burr removal device 603 can perform high-temperature softening treatment on the residual burrs on the surface of the nylon filament bundle. The heating channel 605 can make the heating tube 606 release heat energy evenly, ensuring that the burr area is fully heated, thereby improving the burr removal efficiency. A rotating shaft 604 is fixedly connected to one side of the middle part of the heating edge removal device 603. A handle 607 is fixedly connected to the top of the heating edge removal device 603 on the side away from the rotating shaft 604. The handle 607 allows the staff to easily open the heating edge removal device 603 for maintenance or to replace the heating tube 606, which facilitates the daily inspection and replacement of parts of the equipment and reduces the difficulty of maintenance and downtime.

The first fixed frame 2 and the second fixed frame 3 have grooves inside, and the first transmission roller 201 and the second transmission roller 301 are connected to the rotating shaft inside the groove. The first transmission roller 201 and the second transmission roller 301 are respectively used to guide the nylon filament bundle into and out of the rough edge treatment area. The vertical air pipe 505 and the inclined air pipe 508 are connected to the air pump 501 through the first air pipe 504 and the second air pipe 507 to ensure stable airflow delivery, and together with the heating and deburring device 603 in the processing tank 503, they form a multi-stage burr removal structure. The intake pipe 502 is connected to the ventilation groove 102. The connection end of the intake pipe 502 and the ventilation groove 102 is equipped with a sealing gasket to effectively prevent gas leakage and ensure the airtightness of the air circuit system.

[0018] Working principle: First, the yarn is introduced into the processing tank 503 inside the burr processor 5 through the feed inlet 509 by the first conveyor roller 201, guided by the first transport roller 4 and the second transport roller 401. Inside the processing tank 503, the yarn is precisely guided and positioned by the positioning rollers 602 on the first positioning frame 6 and the second positioning frame 601 to suppress its drift. Then, the yarn passes through the heating channel 605 of the heating and burr removal device 603, where the heating tube 606 heats the surface of the yarn, softening or melting the burrs. Simultaneously, the air pump 501 draws in air through the air inlet pipe 502 and delivers the airflow to the vertical air blowing pipe 505 and the inclined air blowing pipe 508 respectively through the first air pipe 504 and the second air pipe 507. The inclined air blowing pipe 508 blows air at a certain angle onto the yarn, peeling off the softened burrs; the vertical air blowing pipe 505 further cleans the surface. After undergoing multi-stage processing combining airflow and heating, the clean filament bundle is sent out from the discharge port 506 and finally pulled out by the second transmission roller 301, completing the entire stretching and burr removal process.
