Abstract
Description
Technical Field
[0001] The utility model relates to the field of textile two-for-one twisting, in particular to a yarn angle adjustment mechanism for a two-for-one twisting machine. Background Art
[0002] The advent of the two-for-one twister is a prime example of how spinning theory can guide practical application. Due to its high twisting efficiency, large package size, fewer knots, and labor-saving characteristics, the two-for-one twister has become increasingly popular, particularly for products like knot-free synthetic filament yarn and high-end apparel fabrics.
[0003] The two-for-one twister doubles the twisting efficiency, thereby increasing the output of a single spindle; it can directly produce larger bobbins, giving full play to the advantages of large packages and eliminating the need for winding after twisting; the large packages have fewer knots, and 10,000 meters can be knot-free, improving product quality and production efficiency. It is suitable for industrial products and high-end products that have few requirements for knots; the large packages have a long doffing time and fewer broken ends, which can reduce the need for machine operators and improve labor productivity.
[0004] After the two-for-one twisting process, the yarn is wound onto a take-up drum. This requires a mechanism to adjust the yarn's winding angle to match the take-up drum's winding parameters. These parameters vary depending on the type of fiber being processed, so the angle adjustment mechanism must also be adapted accordingly. Furthermore, in the textile industry, the two-for-one twisting machine generates fly lint and fine dust particles during production. These particles are detrimental to maintaining cleanliness and hygiene during production, can adhere to the product, and affect product quality, and can even be absorbed into the lungs of production workers, adversely affecting their health. Therefore, a suction device is installed on the two-for-one twisting machine to absorb the fly lint. The angle adjustment mechanism also requires adjusting the suction device's angle to ensure that the suction port remains parallel to the yarn, allowing the suction device to remove as much fly lint and dust as possible.

[0028] As attached Figure 1-5 The yarn angle adjustment mechanism for a two-for-one twisting machine shown in FIG. 1 includes a frame 1, a guide member 11 provided on the frame 1, the guide member 11 being provided with an arc-shaped slide 111, an abutting wheel 12 being provided in the slide 111 and abutting against the inner wall thereof and slidably connected thereto, a first slide rail 13 being provided on both sides of the guide member 11, a first slide 14 being slidably provided on the first slide rail 13, the first slide 14 sliding in the horizontal direction along the first slide rail 13, a second slide rail 141 being provided on the first slide rail 14, a second slide 142 being slidably provided on the second slide rail 141, the second slide 142 moving in the vertical direction along the second slide rail 141, and the abutting wheel 12 being connected to the second slide 142 via an extension rod 121. The abutting wheel 12 also causes the extension rod 121 to rotate during its movement along the slide 111.
[0029] The frame 1 is further provided with a third slide rail 15, on which an adjustment block 16 is slidably provided. The adjustment block 16 is fixedly connected to a yarn guide rod 17, and a pull rod 161 is connected between the adjustment block 16 and the second slide 142. The adjustment block 16 drives the yarn guide rod 17 to change the winding angle of the yarn 4; further, as the yarn guide rod 17 moves, the adjustment block 16 drives the second slide 142 to move via the pull rod 161.
[0030] A dust collection component is also provided on the frame 1. Since the yarn 4 will generate a large amount of static electricity and some flying fibers and dust will be sandwiched between the yarns 4 during the twisting process, the dust collection component acts on the surface of the yarn 4 to remove the flying fibers and dust attached to the surface of the yarn 4.
[0031] In some embodiments, a push cylinder 18 is further provided on the frame 1, and a movable end of the push cylinder 18 is fixedly connected to the adjustment block 16. The push cylinder 18 drives the adjustment block 16 to move along the third slide rail 15 in the vertical direction.
[0032] In some embodiments, the dust collection assembly includes a dust collecting barrel 21, which is fixedly installed in the middle position of the interior 1. The extension rod 121 is fixedly connected to a dust collection hood 22. One end of the dust collection hood 22 is connected to the dust collecting barrel 21 through a hose 23. An annular dust collecting groove 24 is opened inside the dust collecting barrel 21.
[0033] When the yarn guide rod 17 moves, the dust hood 22 will rotate and move, so that the dust hood 22 remains parallel to the yarn 4 and does not contact the yarn 4 when the angle of the yarn 4 is adjusted, so that the dust collection component has a maximum effective area on the yarn 4, allowing the dust collection component to remove flying flowers and dust on the yarn 4 to the greatest extent.
[0034] In some embodiments, the dust collection assembly further includes a dust box 25. The upper end of the dust box 25 is inserted into the annular dust collection groove 24, and the lower end of the dust box 25 is provided with a stepped protrusion. The stepped protrusion of the dust box 25 is made of a magnetic material, so that the dust box 25 can be fixed to the lower end of the annular dust collection groove 24 under the action of magnetic force, making it convenient for staff to remove the dust box 25 for cleaning during use.
[0035] In some embodiments, the dust collection assembly also includes an axial fan 26; the axial fan 26 is fixedly connected to the dust collecting barrel 21, and the axial fan 26 includes a motor 261 and a suction fan blade 262. A dustproof net 211 is provided at a position corresponding to the suction fan blade 262 in the dust collecting barrel 21, and the suction fan blade 262 is fixedly connected to a connecting shaft 2621, and the connecting shaft 2621 is also connected to a cleaning brush 2622 acting on the dustproof net 211.
[0036] When the utility model is in use, the cylinder 18 drives the adjusting block 16 to slide along the third slide rail 15, thereby driving the yarn guide rod 17 to move, thereby changing the angle at which the yarn 4 is wound onto the yarn drum 3 to adapt to different winding requirements.
[0037] Furthermore, if Figure 2 and Figure 3 As shown, the adjustment block 16 drives the second slide 142 to move through the pull rod 161. Since the abutment wheel 12 will drive the extension rod 121 to rotate a certain angle when moving in the slide groove 111, the dust hood 22 remains parallel to the yarn 4; at the same time, it will also move along the slide groove 111 during the angle rotation process, thereby avoiding the dust hood 22 from contacting the yarn 4 and causing the yarn 4 to break.
[0038] The output end of the motor 261 drives the suction fan blades 262 to rotate, so that the axial flow fan 26 generates suction, and the air is discharged from the air outlet 263, and the dust enters the interior of the dust collection barrel 21 through the dust collection cover 22. The suction fan blades 262 are fixedly connected to the connecting shaft 2621, and the connecting shaft 2621 is also connected to a cleaning brush 2622 that acts on the dustproof net 211. The suction fan blades 262 drive the cleaning brush 2622 to rotate, sweeping the dust on the dustproof net 211 into the interior of the annular dust collecting groove 24, and then falling into the interior of the dust collection box 25, which is convenient for dust collection and avoids affecting the long-term use of the overall device. When the dust in the dust collection box 25 is collected to a certain extent, the staff can overcome the magnetic force to pull out the dust collection box 25, and after clearing the dust in the dust collection box 25, insert the dust collection box 25 into the annular dust collection groove 24.
[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
