Description

Technical Field

[0001] This utility model relates to the field of texturing machine technology, and in particular to a raw yarn bobbin frame for a texturing machine. Background Technology

[0002] Textile machines are textile machinery mainly used to physically deform raw yarns such as polyester POY yarns through processes such as false twisting and stretching, giving the fibers elasticity, fluffiness and crimp, and processing them into elastic yarns such as DTY yarns with medium or low elasticity.

[0003] The raw yarn bobbin holder is a key component of the texturing machine used to place the raw yarn bobbins. It is used to hold the raw yarn bobbins and to install guide tubes on the yarn holder so that the yarns can be guided into the feed rollers.

[0004] When the existing raw yarn bobbin holder continuously feeds the raw yarn to the texturing machine through the guide tube, the yarn will collide and rub against the inlet end of the guide tube, which can easily cause some of the yarns in the strand to break, affecting the processing quality of the subsequent elastic yarn. Utility Model Content

[0005] Therefore, it is necessary to provide a raw yarn bobbin holder for a texturing machine to address the problem that the yarn may collide and rub against the inlet end of the guide tube, which can easily lead to the breakage of some yarns in the stranded yarn.

[0006] Includes: a mounting bracket and a conduit; an anti-breakage mechanism, the anti-breakage mechanism including two smooth tubes connected to the surface of the conduit, annularly distributed guide rods slidably connected to the inner wall of the smooth tubes, ball bearings slidably connected to the ends of the guide rods, springs fixedly connected to the opposite ends of the guide rods and the smooth tubes, and an iron cylinder slidably connected to the surface of the mounting bracket.

[0007] In one embodiment, the inner wall of the iron cylinder is threaded with a bolt, one end of which abuts against the surface of the mounting bracket.

[0008] In one embodiment, the end of the smooth tube is curved into an arc shape, and one end of the smooth tube is trumpet-shaped.

[0009] In one embodiment, a lead screw is rotatably connected to the inner wall of the iron cylinder, and a slider is slidably connected to the inner wall of the iron cylinder, with the inner wall of the slider threadedly connected to the surface of the lead screw.

[0010] In one embodiment, the slider has two movable blocks hinged to its ends, and the movable blocks have friction blocks hinged to their ends.

[0011] In one embodiment, a fixing block is hinged to the end of the friction block, and the end of the fixing block is hinged to the inner wall of the iron cylinder. Through the cooperation of the lead screw, slider, movable block, friction block, and fixing block, the raw wire spool on the iron cylinder is internally supported and fixed, preventing the raw wire from shaking on the iron cylinder due to a reduction in raw wire, thus improving the stability of raw wire conveying.

[0012] In one embodiment, a magnetic block is fixedly connected to the surface of both the bolt and the lead screw, with one end of the magnetic block magnetically attracted to the surface of the iron cylinder. The magnetic block increases the resistance to rotation of the bolt and the lead screw, thereby ensuring that the bolt stably contacts the mounting bracket and that the friction block stably supports the inner wall of the original lead cylinder.

[0013] In one embodiment, dustproof pads are fixedly connected to both sides of the slider, and the other side of the dustproof pads is fixedly connected to the inner wall of the iron cylinder. The dustproof pads effectively seal the opening of the iron cylinder, preventing impurities from adhering to the surface of the lead screw, thereby reducing wear between the lead screw and the slider.

[0014] Beneficial effects 1. By cooperating with the smooth tube, guide rod and spring, the three balls are brought close to each other and smoothly guided and limited the wire. This avoids the situation where the existing wire is prone to collision and friction with the inlet section of the guide tube during the conveying process. This prevents the breakage of some wires in the stranded wire, ensures the conveying effect of the wire, and thus ensures the processing quality of the subsequent elastic wire. 2. By rotating the iron cylinder on the mounting bracket, the direction of the raw wire on the iron cylinder is adjusted, thereby aligning the central axis of the iron cylinder with the inlet of the smooth tube. This facilitates the entry of the raw wire into the smooth tube and helps reduce friction between the raw wire and the smooth tube. The iron cylinder is then locked with bolts after the angle rotation, ensuring stable alignment between the central axis of the iron cylinder and the inlet of the smooth tube, thus further reducing friction between the raw wire and the smooth tube.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figures 1-5 This invention describes a raw yarn bobbin holder for a texturing machine.

[0020] In one embodiment, a texturing machine raw yarn bobbin frame includes: a mounting frame 100 and a wire tube 200; an anti-breakage mechanism 300, the anti-breakage mechanism 300 including two smooth tubes 301 connected to the surface of the wire tube 200, a ring of guide rods 302 slidably connected to the inner wall of the smooth tube 301, a ball bearing 304 slidably connected to the end of the guide rod 302, a spring 303 fixedly connected to the opposite end of the guide rod 302 and the smooth tube 301, an iron cylinder 305 slidably connected to the surface of the mounting frame 100, the end of the smooth tube 301 being curved into an arc shape, and one end of the smooth tube 301 being trumpet-shaped.

[0021] It should be noted that the texturing machine model can be JWK26. The texturing machine is usually composed of mounting frame 100, guide tube 200, iron cylinder 305, feed roller, heating box, false twister, cooling device, stretching device, oiling device and winding device.

[0022] Feed roller: Responsible for drawing the raw yarn from the raw yarn spool and conveying it to the subsequent processing area at a stable speed.

[0023] Heating box: The raw yarn is heated to a certain temperature to increase its plasticity, making it easier for subsequent stretching and deformation operations.

[0024] False twister: One of the core components of a texturing machine, its function is to false twist the heated raw yarn. Through special mechanical structure or aerodynamic principles, the false twister causes the raw yarn to produce twist within a certain length, thereby giving the fiber crimp and elasticity.

[0025] Cooling device: Located after the false twister, it is used to quickly cool the raw yarn that has undergone false twisting deformation, so as to fix the already formed crimp and twist.

[0026] Stretching device: This device stretches the raw yarn before and after false twisting to adjust the internal structure and physical properties of the fiber. The stretching device typically consists of multiple rollers, and the stretching effect is achieved through the speed difference between the different rollers.

[0027] Oiling device: Adds appropriate oil to the processed elastic yarn to improve its smoothness, antistatic properties and cohesion, facilitating subsequent textile processing.

[0028] Winding device: The processed elastic yarn is wound onto a bobbin according to certain forming requirements to form finished DTY yarn.

[0029] The smooth tube 301, guide rod 302, spring 303 and ball 304 are all made of 304 stainless steel, which has excellent smoothness and wear resistance, thereby reducing the friction between the ball 304 and the polyester POY yarn.

[0030] In this embodiment, when polyester POY yarn needs to be processed into elastic yarn, the raw yarn bobbin is placed on the iron cylinder 305, and one end of the polyester POY yarn on the raw yarn bobbin is pulled into three ball bearings 304 and guided into the guide tube 200 and the feed roller. The feed roller delivers the raw yarn to the heating box at a stable speed. The elastic force of the spring 303 pushes the guide rod 302 toward the polyester POY yarn, so that the ball bearings 304 roll against the surface of the polyester POY yarn. Because the end of the smooth tube 301 is curved into an arc shape and one end of the smooth tube 301 is trumpet-shaped, the friction between the polyester POY yarn and the smooth tube 301 is reduced, thereby reducing the friction or collision when the polyester POY yarn enters the guide tube.

[0031] After entering the heating chamber, the raw filament is heated above its glass transition temperature, typically between 180-220°C, giving the fiber molecular chains a certain degree of mobility, creating conditions for subsequent stretching and deformation. The heated raw filament then enters a false twister, which applies twist to it. During false twisting, one end of the filament is fixed while the other end rotates, causing the filament to form an alternating S-twist and Z-twist structure within a certain length. When the raw filament leaves the false twister, the twist disappears, but the fiber has undergone plastic deformation, forming a crimp and elasticity.

[0032] The false-twist yarn immediately enters the cooling device, where forced cooling rapidly lowers the fiber temperature, fixing the curl and twist formed by the false-twist deformation. After cooling and setting, the yarn is stretched by the stretching device to further adjust the internal structure and physical properties of the fiber. The stretched elastic yarn is then coated with an appropriate amount of oil by the oiling device. Finally, the processed elastic yarn is wound onto a bobbin by the winding device to form a finished DTY yarn with a certain shape and density.

[0033] like Figure 3 As shown, the inner wall of the iron cylinder 305 is threaded with a bolt 306, one end of which abuts against the surface of the mounting bracket 100.

[0034] In this embodiment, when it is necessary to align the central axis of the iron cylinder 305 with the inlet of the smooth tube 301, the rotating bolt 306 is moved away from the surface of the mounting bracket 100 to release the lock on the iron cylinder 305. The iron cylinder 305 is then pushed to rotate at a suitable angle in the mounting bracket 100 so that the central axis of the iron cylinder 305 is aligned with the inlet of the smooth tube 301. The rotating bolt 306 is then used to spiral forward inside the iron cylinder 305 and press against the surface of the mounting bracket 100, thereby locking the iron cylinder 305.

[0035] like Figure 3 As shown, a lead screw 312 is rotatably connected to the inner wall of the iron cylinder 305, and a slider 311 is slidably connected to the inner wall of the iron cylinder 305. The inner wall of the slider 311 is threaded to the surface of the lead screw 312. Two movable blocks 310 are hinged to the end of the slider 311. A friction block 309 is hinged to the end of the movable block 310. A fixed block 308 is hinged to the end of the friction block 309. The end of the fixed block 308 is hinged to the inner wall of the iron cylinder 305. A magnetic block 307 is fixedly connected to both the bolt 306 and the surface of the lead screw 312. One end of the magnetic block 307 is magnetically attracted to the surface of the iron cylinder 305. Dustproof pads 313 are fixedly connected to both sides of the slider 311. The other side of the dustproof pad 313 is fixedly connected to the inner wall of the iron cylinder 305.

[0036] It should be noted that bolt 306 and friction block 309 are both chromium-molybdenum alloy steel components, which have high strength, toughness, wear resistance and a large coefficient of friction. This ensures that the end of bolt 306 is stably pressed against the mounting bracket 100, thereby ensuring the stability of iron cylinder 305 locked on the mounting bracket 100, and ensuring that friction block 309 is stably pressed against the inner wall of the original wire cylinder, thereby ensuring the stability of the original wire cylinder fixed on iron cylinder 305.

[0037] The surface of the dustproof pad 313 is corrugated. The dustproof pad 313 is a silicone rubber component with excellent elasticity and sealing performance.

[0038] In this embodiment, the raw yarn spool is sleeved on the iron cylinder 305. The screw 312 is rotated to make the slider 311 move laterally inside the iron cylinder 305, thereby pushing the two friction blocks 309 away from each other and pressing against the inner wall of the raw yarn spool, thereby fixing the raw yarn spool on the iron cylinder 305.

[0039] Working principle: The iron cylinder 305 is rotated at a suitable angle in the mounting frame 100 so that the central axis of the iron cylinder 305 is aligned with the inlet of the smooth tube 301. The bolt 306 is rotated so that the bolt 306 spirals forward inside the iron cylinder 305 and presses against the surface of the mounting frame 100, so that the magnetic block 307 on the bolt 306 is attracted to the iron cylinder 305. The filament spool is sleeved on the iron cylinder 305. The lead screw 312 is rotated so that the slider 311 moves laterally inside the iron cylinder 305, thereby pushing the two friction blocks 309 away from each other and pressing against the inner wall of the filament spool, thereby fixing the filament spool on the iron cylinder 305. The elastic force of the spring 303 pushes the guide rod 302 toward the polyester POY filament, so that the ball 304 rolls against the surface of the polyester POY filament, thereby smoothly guiding and limiting the polyester POY filament, thereby reducing the friction or collision when the polyester POY filament enters the guide tube.

[0040] It should be noted that the mounting bracket 100, conduit 200, iron cylinder 305 and magnetic block 307 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
