[0032] The utility model is further described below in conjunction with the accompanying drawings.
[0033] The same or similar numbers in the drawings of the embodiments of the present invention correspond to the same or similar parts; in the description of the present invention, it should be understood that if the terms "top", "bottom", "left", "right", "front", "back", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0034] Please refer to Figure 1-Figure 7 An embodiment of the utility model provides a multi-strand composite DTY differentiation production device, including a roller assembly, a heating and cooling assembly arranged downstream of the first roller 1, a wire moving plate 11 arranged downstream of the heating and cooling assembly, and a wire guide assembly, the roller assembly at least includes a first roller 1, a second roller 2 and a third roller 3, the second roller 2 and the first roller 1 are arranged in sequence along the spinning direction, the first roller 1 is located below the second roller 2, the heating and cooling assembly is used to heat the POY yarn first and then cool it, the third roller 3 is located downstream of the wire moving plate 11, and the wire guide assembly at least includes a first wire guide 6 installed on the first roller 1, a first guide wheel 7 arranged between the first roller 1 and the heating and cooling assembly, a second guide wheel 8 installed on the heating and cooling assembly, and a second wire guide 9 installed on the wire moving plate 11.
[0035] The roller assembly comprises a first roller 1 and a second roller 2, wherein the first roller 1 and the second roller 2 are respectively used for feeding two strands of POY yarn. The POY yarn on the first roller 1 follows a conventional spinning route, and the POY yarn on the second roller 2 can be guided by a first guide wheel 7, a second guide wheel 8 and a second yarn guide 9, and merged with the POY yarn on the first roller 1 to enter the third roller 3, so that the composite spinning of the two strands of POY yarn can be achieved. The first roller 1 and the second roller 2 have the functions of holding and stretching, and can increase the roller according to the number of strands of POY yarn, so as to achieve the composite spinning of multiple strands of POY yarn, produce differentiated fibers, and make up for the shortcoming that a single-strand machine cannot produce composite differentiated fibers. The second guide wheel allows the newly added POY yarn to be smoothly merged with the POY yarn passing through the first roller 1 to enter the third roller 3, thereby reducing the generation of hairy yarn to a certain extent, so as to carry out subsequent winding normally. The yarn guide assembly plays the role of straightening the yarn path, preventing the yarn from being broken due to friction caused by the misalignment of the yarn path during spinning, and improving product quality.
[0036] Specifically, the POY yarn has two strands, one of which passes through the first roller 1, the heat box 4, the cooling plate 5, the false twister 10, the wire moving plate 11 and the third roller 3 in sequence, and the other strand of the POY yarn passes through the second roller 2, the first guide wheel 7, the second guide wheel 8, the second wire guide 9 and the third roller 3 in sequence. The first guide wheel 7 and the second guide wheel 8 play a guiding role while reducing friction, and the second wire guide 9 can guide the wire path.
[0037] like Figure 2 As shown, the roller assembly also includes a fourth roller 12, and the fourth roller 12, the second roller 2 and the first roller 1 are arranged along the spinning direction. The wire guide assembly also includes a third wire guide 13 arranged on the second roller 2. The fourth roller 12 is added to the roller assembly, and the third wire guide 13 is added according to the fourth roller 12, so that the fourth roller 12 can feed the third strand of POY yarn to achieve composite spinning of three strands of POY yarn. The obtained differentiated fibers are more functional and can be installed according to different production requirements, having the production capacity of both a stranding machine and a single strand machine.
[0038] Specifically, the POY yarn has three strands, the first strand of the POY yarn passes through the first roller 1, the second strand of the POY yarn passes through the second roller 2 and the first yarn guide 6 in sequence, and after being combined with the first strand of the POY yarn, passes through the hot box 4, the cooling plate 5, the false twister 10, the yarn moving plate 11 and the third roller 3 in sequence, and the third strand of the POY yarn passes through the fourth roller 12, the third yarn guide 13, the first guide wheel 7, the second guide wheel 8, the second yarn guide 9 and the third roller 3 in sequence. The first guide wheel 7 and the second guide wheel 8 play a guiding role while reducing friction. The first yarn guide 6, the second yarn guide 9 and the third yarn guide 13 can guide the yarn path.
[0039] The first guide wheel 7, the second guide wheel 8, the first wire guide 6, the second wire guide 9 and the third wire guide 13 can be installed in the form of a mounting rod or a mounting plate, which will not be described in detail.
[0040] like Figure 1 and Figure 2 As shown, the heating and cooling assembly includes a heat box 4 and a cooling plate 5 which are sequentially arranged along the spinning direction. The heat box 4 heats the POY yarn, and then the cooling plate 5 cools the POY yarn.
[0041] Further, such as Figure 1 and Figure 2 As shown, the second guide wheel 8 is installed on the cooling plate 5, and the cooling plate 5 is closer to the wire plate 11. After passing through the second guide wheel 8 and entering the second wire guide 9, the wire path will not deviate.
[0042] like Figure 1 and Figure 2As shown, a false twister 10 is arranged between the cooling plate 5 and the wire moving plate 11. The false twister 10 can control the two ends of the POY yarn to not rotate and apply twist in the middle, thereby increasing the strength of the yarn, reducing the unexpected elongation of the spinning, enhancing the elasticity of the POY yarn, reducing the hairiness and improving the surface properties, reducing the torque and twist of the post-processing, and improving the fiber quality.
[0043] like Figure 1 and Figure 2 As shown, the device also includes a mounting frame 14, and the roller assembly, heating and cooling assembly, and wire moving plate 11 are mounted on the mounting frame 14. The roller assembly, heating and cooling assembly, and wire moving plate 11 are mounted on one mounting frame 14 for better integrity.
[0044] like Figure 3 As shown, a double-wire-path guide block 15 is arranged upstream of the first roller 1. According to the number of strands of the POY yarn, the double-wire-path guide block 15 is arranged, which has a better guide effect and better spinning stability.
[0045] like Figure 4 As shown, a three-wire guide block 16 is provided upstream of the fourth roller 12. According to the number of strands of the POY yarn, the three-wire guide block 16 is provided, which has a better guide effect and better spinning stability.
[0046] Specifically, Figure 5-Figure 7 As shown, the frame 17 is composed of a plurality of horizontal plates 1701 and vertical tubes 1702, a plurality of hanging rods 18 are arranged at intervals on the upper edge of the vertical tubes 1702, the POY wire is wound around a wire drum 19, and the wire drum 19 is hung on the hanging rods 18, the frame 17 is a 4-layer or 6-layer structure, a support plate 22 is installed on the frame 17, a wire guide tube 20 is inserted on the frame 17, the POY wire enters from the bottom of the wire guide tube 20, and then exits from the head of the wire guide tube 20 and passes through a double-wire guide block 15 or a three-wire guide block 16, the double-wire guide block 15 or the three-wire guide block 16 is installed on the vertical rod 21, the structure is simple, the support stability is good, and the production is convenient.
