Description

Technical Field

[0001] This utility model relates to the field of irregular network yarn production technology, and in particular to a stretching device for producing irregular network yarn. Background Technology

[0002] Shaped network yarn is a new type of fiber material with a special structure and excellent properties. It is produced through a special spinning process and has a unique cross-section, distinct from the conventional circular cross-section, such as triangular, trefoil, or flat shapes. These special cross-sectional shapes endow shaped network yarn with many unique properties: First, the irregular cross-section increases the gaps between fibers, significantly improving the bulkiness and breathability of the fabric, making clothing made from it more comfortable to wear; second, the special cross-sectional structure alters the way light is reflected and refracted, giving the fabric a unique luster effect, which can be used to produce high-end fabrics with special appearances; third, the unique structure of shaped network yarn gives it good anti-pilling properties, effectively extending the service life of the fabric. In the production process of shaped network yarn, stretching is a crucial step. Stretching can adjust the fineness, strength, and elasticity of the yarn, directly affecting the final quality and application effect of the shaped network yarn.

[0003] Chinese patent CN222100264U discloses a polyester filament thermal stretching device, including a base plate. Two support columns are fixedly connected to the upper end of the base plate, and a first heating plate is fixedly connected to the upper end of the two support columns. Brackets are fixedly connected to both sides of the base plate. A mounting hole is opened through the upper end of the bracket. A first electric push rod is fixedly connected inside the mounting hole, and a second heating plate is fixedly connected to the telescopic end of the first electric push rod.

[0004] The aforementioned existing technology has some shortcomings. While the polyester filament is stretched by lifting it upwards using a second electric push rod, this stretching method is simple but ineffective and cannot significantly improve product quality. Furthermore, before heating, the surface of the filament is prone to adhering to dust, lint, and other impurities. If these impurities are not cleaned in time, they will negatively impact the quality of the filament, causing defects and consequently affecting product quality. Utility Model Content

[0022] Please see Figure 1-4 This utility model provides a stretching device for producing irregularly shaped network yarns, comprising: Base 1, with a support rod 11 fixedly connected to the center of the upper side wall of base 1; The wire feeding mechanism 2 is located on one side of the upper side wall of the base 1. The wire feeding mechanism 2 is used to place the irregularly shaped network wire roll to be stretched. The wire take-up mechanism 3 is located on the other side of the upper side wall of the base 1. The wire take-up mechanism 3 is used to collect the stretched irregular network wires. The wire threading box 4 is fixedly installed at the upper end of the support rod 11; Heating mechanism 5 is installed on the threading box 4 and is used to heat the shaped network yarn that has undergone initial stretching. Dust removal mechanism 6 is installed inside the threading box 4. Dust removal mechanism 6 is used to remove dust from the irregular network yarn after the initial stretching. Two stretching mechanisms 7 are provided on the upper side wall of the base 1 and located on both sides of the threading box 4. The stretching mechanisms 7 are used to stretch the irregular network yarn. Two tensioning mechanisms 8 are provided on the upper side wall of the base 1 and are respectively close to the yarn feeding mechanism 2 and the yarn taking mechanism 3. The tensioning mechanisms 8 are used to control the tension of the irregular network yarn.

[0023] By setting up the above structure, thermal stretching of irregularly shaped network wires is achieved, and the stretching effect is improved, thereby improving product quality.

[0024] The heating mechanism 5 includes several heating wires 51, which are installed between the inner walls of both sides of the wire threading box 4. Two symmetrically distributed air intake fans 52 are installed on the upper side wall of the wire threading box 4.

[0025] The above structure enables the heating of irregularly shaped network yarns entering the threading box 4.

[0026] The dust removal mechanism 6 includes two rotating shafts 61, which are symmetrically arranged on one inner wall of the threading box 4. One end of the rotating shaft 61 is fixedly connected to a turntable 62. Multiple soft paddles 63 are arranged around the outer wall of the turntable 62. A transmission wheel 64 is fixedly sleeved on the rotating shaft 61. The two transmission wheels 64 are driven by a toothed belt 65. A dust removal motor 66 is installed on one outer wall of the threading box 4. The output shaft end of the dust removal motor 66 is fixedly connected to one of the rotating shafts 61. A dust suction hood 67 is provided on the lower inner wall of the threading box 4. An air pipe 68 is connected to the bottom of the dust suction hood 67.

[0027] The above structure enables dust removal of irregularly shaped network yarns, promptly removing dust, lint, and other impurities from the yarn surface, effectively preventing impurities from affecting the yarn quality.

[0028] The stretching mechanism 7 includes a first bracket 71 fixedly mounted on the upper side wall of the base 1. A lower stretching roller 72 is rotatably mounted between the inner walls of the two sides of the first bracket 71. A sliding groove 73 is provided on both sides of the first bracket 71. A sliding plate 74 is slidably mounted in the sliding groove 73. An upper stretching roller 75 is rotatably mounted between the two sliding plates 74.

An adjusting plate 77 is fixedly connected between the two sliding plates 74.

[0029] With the above structure, the irregular network filament can be stretched. The lower stretching roller 72 and the upper stretching roller 75 operate at different speeds. When the irregular network filament moves between the two stretching rollers with different speeds, the filament will be subjected to tension due to the speed difference of the stretching rollers, and thus be stretched and thinned.

[0030] The tensioning mechanism 8 includes a second bracket 81 fixedly mounted on the upper side wall of the base 1, a U-shaped frame 82 slidably mounted between the inner walls of the two sides of the second bracket 81, and a tensioning roller 83 mounted between the inner walls of the two sides of the U-shaped frame 82.

[0031] The above structure allows for the tensioning of irregularly shaped network wires.

[0032] The first bracket 71 and the second bracket 81 are both fitted with internal threaded sleeves 9 on their upper side walls. The internal threaded sleeves 9 are internally threaded and connected to adjusting screws 91. The lower end of the adjusting screws 91 is rotatably connected to the corresponding adjusting plate 77 or U-shaped frame 82, and the upper end of the adjusting screws 91 is fixedly connected to an adjusting handwheel 92.

[0033] With the above structure, rotating the adjusting handwheel 92 can drive the adjusting screw 91 to rotate. When the adjusting screw 91 rotates, under the action of the internal threaded sleeve 9, it can drive the adjusting plate 77 or the U-shaped frame 82 to move up and down, thereby adjusting the height of the U-shaped frame 82 or the adjusting plate 77. The height change of the adjusting plate 77 can be adapted to different specifications of irregularly shaped network yarns, and the height change of the U-shaped frame 82 can adjust the tension.

[0034] Two symmetrically distributed semiconductor cooling fans 10 are installed on one side wall of one of the second brackets 81, and an air guide shroud 101 is fixedly connected to the air outlet of the semiconductor cooling fan 10.

[0035] The above structure allows for rapid cooling and shaping of the irregularly shaped network yarn after secondary stretching, further improving product quality.

[0036] It should be noted that the semiconductor air cooler 10 is a mature existing technology that uses the thermoelectric effect of semiconductor materials to achieve cooling. Therefore, its specific structure will not be described in detail in this article.

[0037] The unwinding mechanism 2 includes an unwinding frame 21 fixedly mounted on the upper side wall of the base 1, and an unwinding shaft 22 rotatably mounted on the unwinding frame 21 for mounting irregularly shaped network yarn rolls and unwinding them.

[0038] The take-up mechanism 3 includes a take-up frame 31 fixedly mounted on the upper side wall of the base 1. A take-up motor 32 is mounted on one outer wall of the take-up frame 31. A take-up shaft 33 is rotatably mounted on the take-up frame 31. The output shaft of the take-up motor 32 is fixedly connected to one end of the take-up shaft 33. The output shaft of the take-up motor 32 can drive the take-up shaft 33 to rotate, which is used to collect the stretched and cooled shaped network yarn.

[0039] It should be noted that this utility model is a stretching device for producing irregularly shaped network yarn. In use, the irregularly shaped network yarn roll is mounted on the unwinding shaft 22, which rotates on the unwinding frame 21. The irregularly shaped network yarn is released from the roll. The initial tension of the irregularly shaped network yarn is adjusted as needed. For example, when the diameter of the roll is large, the tension can be appropriately increased to prevent the yarn from loosening and swaying during release; when the diameter of the roll is small, the tension is correspondingly reduced to avoid overstretching. The position of the tension roller 83 is adjusted by rotating the adjusting handwheel on the second bracket 81 near the unwinding mechanism 2, so that the irregularly shaped network yarn enters the first stretching mechanism 7 with a suitable tension and is pre-stretched. After pre-stretching, the irregularly shaped network yarn enters the threading box 4. The air intake fan 52 draws outside air into the threading box 4 and, after being heated by the heating wire 51, blows it onto the irregularly shaped network yarn. Heating is performed on the shaped network wires. The output shaft of the dust removal motor 66 drives the rotating shaft 61 to rotate. The rotation of the rotating shaft 61 drives the transmission wheel 64 and the turntable 62 to rotate. Through the transmission of the toothed belt 65, the two turntables 62 rotate together. The rotation of the turntables 62 drives the paddle 63 to rotate. The paddle 63 paddles the shaped network wires, causing them to vibrate and shake off the impurities on their surface. Under the action of the external vacuum cleaner, the fallen impurities are sucked into the vacuum hood 67 and then enter the dust bag of the external vacuum cleaner through the air pipe 68. After being heated and dusted, the shaped network wires enter the second stretching mechanism 7 for secondary stretching. When the shaped network wires after secondary stretching pass through the second tension roller 83, the semiconductor cooling fan 10 blows out cold air. The cold air is blown onto the surface of the shaped network wires through the air guide hood 101, which quickly cools and positions them. Then, they are wound onto the take-up shaft 33.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
