A core layer twist-free core-spun yarn, yarn forming system and method

Abstract

The present invention discloses a core-layer untwisted core-spun yarn, a yarn-forming system, and a method, and relates to the technical field of yarn production. The core-layer untwisted core-spun yarn, the yarn-forming system, and the method utilize a yarn impurity removal mechanism to utilize the high-speed wind generated by a fan to blow out the core-layer untwisted core-spun yarn through a first annular air duct and a second annular air duct as the yarn passes through the yarn impurity removal mechanism, thereby blowing off short fibers and impurities attached to the surface of the core-layer untwisted core-spun yarn. This ensures that the core-layer untwisted core-spun yarn is in a clean state when passing through the yarn impurity removal mechanism. The provision of two symmetrical first and second annular air ducts allows for two impurity removal operations on the passing core-layer untwisted core-spun yarn, thereby improving the impurity cleaning effect and cleaning efficiency. The first and second air nozzles are both distributed in an annular array, so that the impurities and short fibers blown off are blown into the interior of the cylinder, thereby facilitating the collection and storage of the impurities and short fibers by a subsequent storage component.

[0046] The embodiment of the present invention further discloses a core layer twist-free core-spun yarn, which is made by using a core layer twist-free core-spun yarn forming system.

[0047] The embodiment of the present invention further provides a method for forming a core layer twist-free core-spun yarn, the specific method comprising the following steps:

[0048] Step 1: Preparation before yarn formation: First, the fiber raw materials of the core layer untwisted core-spun yarn are placed in the first raw material component and the second raw material component respectively, and the fiber raw materials of the core layer untwisted core-spun yarn are all passed through the yarn forming mechanism 6 to be formed;

[0049] Step 2: Cleaning impurities: After the formed core layer untwisted core-spun yarn passes through the yarn impurity removal mechanism 9, the short fibers and impurities attached to the surface are blown off and the short fibers and impurities are collected and compressed;

[0050] Step 3: Collect the core layer untwisted core-spun yarn: Wind the core layer untwisted core-spun yarn on the winding component. After winding is completed, disassemble the winding component for storage. Then replace it with another winding component and connect it to the motor output shaft.

[0051] In the present invention, a fan and a controller for controlling the fan are fixedly arranged on one side of the top of the yarn forming mechanism 6. The fan is used to provide wind support to the yarn impurity removing mechanism 9, and the controller is used to control the opening or closing of the fan.

[0052] The yarn impurity removal mechanism works, and the gas blown out by the fan is respectively transported to the first annular air pipe 922 and the second annular air pipe 923 through the air delivery pipe 927, and blown out through the multiple first air nozzles 924 and the second air nozzles 925 that are evenly distributed. The high-speed flowing air lifts the formed core layer untwisted core-spun yarn and separates it from the inner walls of the first annular air pipe 922 and the second annular air pipe 923. Therefore, when the core layer untwisted core-spun yarn passes through the cylinder 921, the impurities and short fibers attached to its surface are blown away by the air flow. Since the blowing angles of the first air nozzle 924 and the second air nozzle 925 are both toward the center of the cylinder 921, the short fibers and impurities blown away are accompanied by As the air flows through the exhaust port 926, it enters into the plurality of storage assemblies 93. Since there is a gap between the conical baffle 935 and the inner wall of the conical through hole 934 when the top plate 937 is not acted upon by an external force, the short fibers and impurities enter the upper storage cylinder 93111 through the inlet and gap at the bottom of the lower storage cylinder 9312, and the air is discharged through the filter hole at the top of the upper storage cylinder 93111. After the impurities and short fibers enter the upper storage cylinder 9311, they are acted upon by the conical guide blocks arranged around the top of the compression block 933 and slide toward the inner wall of the upper storage cylinder 9311. At this time, the servo motor 97 drives the gear 98 to work, and the servo motor 97 is programmed to do so. The control is to make it rotate reciprocatingly within an angle range of twenty degrees. As the gear 98 and the arc-shaped rack 942 are engaged, the driving ring 941 rotates, and the first driving block 944 or the second driving block 946 pushes the top plate 937 to move upward, and the transmission rod 936 drives the conical baffle 935 to move upward. After it moves to a certain height, it contacts the bottom of the compression block 933. The compression block 933 and the conical baffle 935 move upward synchronously. As the amount of short fibers and impurities increases, the compression block 933 moves upward while squeezing the short fibers and impurities. The clustered short fibers and impurities squeeze each other to achieve an extrusion effect. Due to the two adjacent first driving blocks 944 and the second driving block 935, the compression block 933 and the conical baffle 935 move upward synchronously. Blocks 946 are located at different ends of the two adjacent first long strip openings 943 and second long strip openings 945, so that when one of the first driving blocks 944 pushes the top plate 937 upward, the second driving block 946 is in an inoperative state, so that half of the storage components 93 are in an inoperative state, and the conical through hole 934 and the filter hole on the top of the upper storage cylinder 9311 are in a connected state, thereby ensuring that the gas blown out of the air nozzle can be continuously and smoothly discharged through the storage component 93. After the core layer untwisted core-spun yarn is formed, the sealing plate 9314 is disassembled, and the short fibers and impurity mixture inside the upper storage cylinder 93111 can be removed using tools.
