Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of parallel yarn covering, and particularly relates to a parallel yarn covering heat setting device. Background Technique
[0002] Parallel yarn covering is a textile technology, which mainly involves wrapping a yarn or filament around the outside of another yarn or filament, and wrapping the core yarn in the form of a helix. This technology is usually used to produce special structure yarns, where one yarn serves as the core filament and the other yarn or filament serves as the outer wrapping material, which is wrapped around the core filament to form a yarn with specific structures and properties. There are various methods for parallel yarn covering, including but not limited to air vortex core-spun yarn, self-twist wrapped yarn, rotor core-spun yarn, etc. This technology is not limited to using specific fiber materials, but various natural fibers and chemical fibers can be used as the core filaments and outer wrapping materials according to needs, so as to produce yarns with different characteristics and uses.
[0003] After the production of the covered yarn is completed, it needs to be subjected to hot pressing and setting treatment. The hot pressing and setting of the hot covered yarn can cause thermoplastic changes in the fibers. The fibers become soft at high temperatures, then regain their new shape during the cooling process and maintain this shape. This process is called heat setting. The purpose is to make the covered yarn have the required shape and elastic properties. When performing heat setting treatment on the covered yarn, generally, hot pressing or hot steam heating methods are used. The former is prone to cause partial yarn breakage due to high temperatures, and the latter lacks the pressure setting effect. Both have deficiencies. Moreover, after hot pressing and setting, the cooling method mostly used is fan cooling, and the yarn cooling path is short, resulting in a slow cooling and setting rate and an insignificant effect. Therefore, improvement is urgently needed. Content of the Utility Model
[0004] The purpose of the utility model is to provide a parallel yarn covering heat setting device to solve the problems raised in the above background technique.
[0005] To achieve the above object, the present utility model provides the following technical solutions: A yarn parallel winding and heat setting device, including a yarn rack, a heat setting box, a steam heating box, a cooling box and a hot pressing roller. The heat setting box is fixed on one side of the yarn parallel winding rack. The steam heating box is installed inside the heat setting box, and a steam chamber and a heating chamber are respectively arranged at the top and bottom of the steam heating box. A first telescopic driving member and a second telescopic driving member are respectively installed at the top and bottom of the heat setting box on both sides of the steam heating box, and a first hot pressing head and a second hot pressing head are respectively installed at the output ends of the first telescopic driving member and the second telescopic driving member. The hot pressing rollers are all installed inside the first hot pressing head and the second hot pressing head. A yarn parallel winding rack is installed between the yarn rack and the heat setting box, and a yarn parallel winding roller and a covering mechanism are respectively installed on the outer wall of the yarn parallel winding rack. The cooling box is installed on one side of the heat setting box, and hollow cooling plates are installed inside the cooling box, and cooling pipes are installed inside the hollow cooling plates. A fan is installed on the outer wall on one side of the hollow cooling plate.
[0006] Preferably, guide rollers are installed inside the cooling box to facilitate guiding the yarn.
[0007] Preferably, heating rods are installed at the bottom of the heating chamber to facilitate heating water to generate steam.
[0008] Preferably, a steam collecting hood is installed at the top of the heating chamber, and a conduit is installed at the top end of the steam collecting hood. The top end of the conduit extends into the steam chamber and is communicated with a steam spray pipe to facilitate collecting the steam.
[0009] Preferably, a steam spray pipe is installed at the bottom of the steam chamber, and the steam chamber is communicated with the heating chamber.
[0010] Preferably, heating wires are installed at the edge positions inside the hot pressing rollers to provide heat for the hot pressing rollers.
[0011] Preferably, both ends of the cooling pipe extend outside the hollow cooling plate and are respectively installed with a liquid inlet pipe and a liquid outlet pipe.
[0012] Preferably, the outer walls on both sides of the hollow cooling plate are of a mesh structure.
[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] When the covered yarn passes through the heat setting box, the first telescopic driving member drives the first hot pressing head to move, and the second telescopic driving member drives the second hot pressing head to move, so that the hot pressing roller hot presses the covered yarn through the heating wire. When the covered yarn passes through the steam chamber inside the steam heating box, the heating rod inside the heating chamber heats water into steam, and the steam enters the steam nozzle through the conduit after being collected by the steam collecting hood. The steam sprays out from the steam nozzle to heat the yarn. This device adopts a heat setting method combining hot pressing and steam heating, and the hot pressing is before and after the steam, so that the covered yarn undergoes hot pressing, steam heating, and hot pressing alternately, which can prevent the yarn from breaking and has a pressure setting effect, thus improving the hot pressing setting effect;
[0015] When the covered yarn passes through the yarn guiding roller inside the cooling box, the external coolant is introduced into the cooling pipe through the liquid inlet pipe. The fan operates to make the air pass through the cooling pipe inside the hollow cooling plate and cool down to form cold air, which is then blown towards the covered yarn to cool and set the covered yarn, thereby accelerating the cooling rate. Since the covered yarn has a long movement path inside the cooling box, the covered yarn is fully cooled and the cooling and setting effect is good. Brief Description of the Drawings

The hot pressing rollers 18 are all installed inside the first hot pressing head 7 and the second hot pressing head 10;
[0024] Specifically, when the covered yarn passes through the heat setting box 5, the first telescopic driving member 6 drives the first hot pressing head 7 to move, and the second telescopic driving member 9 drives the second hot pressing head 10 to move, so that the hot pressing rollers 18 hot press the covered yarn through the heating wire 19. When the covered yarn passes through the steam chamber 17 inside the steam heating box 8, the heating rod 13 inside the heating chamber 12 heats the water into steam. After the steam is collected by the steam collecting hood 14, it enters the steam spray pipe 16 through the conduit 15, and the steam sprays out from the steam spray pipe 16 to heat the yarn. This device adopts a heat setting method combining hot pressing and steam heating, and the hot pressing is before and after the steam, so that the covered yarn undergoes hot pressing, steam heating, and hot pressing alternately, thereby preventing the yarn from breaking and having a pressure setting effect, thus improving the hot pressing setting effect;
[0025] A yarn doubling and covering rack 2 is installed between the yarn rack 1 and the heat setting box 5, and a yarn doubling roller 3 and a covering mechanism 4 are respectively installed on the outer wall of the yarn doubling and covering rack 2;
[0026] The cooling box 11 is installed on one side of the heat setting box 5, and hollow cooling plates 21 are installed inside the cooling box 11, and cooling pipes 23 are installed inside the hollow cooling plates 21. A fan 22 is installed on the outer wall on one side of the hollow cooling plate 21;
[0027] Specifically, when the covered yarn passes by the yarn guide roller 20 inside the cooling box 11, the external coolant is introduced into the cooling pipe 23 through the liquid inlet pipe 24. The fan 22 operates to make the air pass through the cooling pipe 23 inside the hollow cooling plate 21 and then form cold air after cooling, which is blown onto the covered yarn to cool and shape the covered yarn, thereby accelerating the cooling rate. Since the covered yarn has a long movement path inside the cooling box 11, the covered yarn is fully cooled and the cooling and shaping effect is good.
[0028] Yarn guide rollers 20 are installed inside the cooling box 11.
[0029] Heating rods 13 are installed at the bottom of the heating chamber 12.

[0035] When the embodiment of the present application is in use: First, the yarn on the yarn stand 1 is warped by the warping roller 3 on the warping and covering stand 2 and then covered by the covering mechanism 4. The covering mechanism 4 is a cyclone covering, which is a prior art and will not be elaborated here. Then, when the covered yarn passes through the heat setting box 5, the first telescopic driving member 6 drives the first hot pressing head 7 to move, and the second telescopic driving member 9 drives the second hot pressing head 10 to move, so that the hot pressing roller 18 hot presses the covered yarn through the heating wire 19. When the covered yarn passes through the steam chamber 17 inside the steam heating box 8, the heating rod 13 inside the heating chamber 12 heats the water into steam. After the steam is collected by the steam collecting hood 14, it enters the steam nozzle 16 through the conduit 15, and the steam sprays out from the steam nozzle 16 to heat the yarn. The device adopts a heat setting method combining hot pressing and steam heating, and the hot pressing is before and after the steam, so that the covered yarn undergoes hot pressing, steam heating, and hot pressing alternately, thereby preventing the yarn from breaking and having a pressure setting effect, thus improving the hot pressing setting effect. Then, when the covered yarn passes through the yarn guiding roller 20 inside the cooling box 11, the external coolant is introduced into the cooling pipe 23 through the liquid inlet pipe 24. The fan 22 operates so that the wind passes through the cooling pipe 23 inside the hollow cooling plate 21, cools down to form cold air and blows towards the covered yarn to cool and set the covered yarn, thereby accelerating the cooling rate. Since the covered yarn has a long movement path inside the cooling box 11, the covered yarn is fully cooled and the cooling and setting effect is good. Finally, the well-set covered yarn is led out.
