Description

Technical Field

[0001] The utility model relates to the technical field of false twist texturing machines, in particular to a yarn roller used in false twist texturing machines. Background Art

[0002] False twist deformation is a process in which the yarn is first heated and twisted, and then cooled and untwisted. The deformed yarn is called deformed elastic yarn. The false twisting process is completed on a false twisting machine, which mainly includes three continuous basic processes: twisting, heat setting, and untwisting. The yarn is twisted with a high twist above the softening temperature to produce plastic irreversible twisting deformation, heated to eliminate the torsional stress caused by twisting, and cooled to fix the twisting deformation. After untwisting, the twist number of the yarn is zero, but the yarn is left with a spiral twist, which makes the yarn fluffy, elastic and stretchable.

[0003] The yarn roller for the existing false twist texturing machine is generally aimed at improving the problem that when the existing yarn roller is performing false twist texturing, the external yarn of the line roller rotates under the pull of the false twister, and the stability of the line release decreases when the line roller rotates, thereby affecting the quality of the false twist. For example, a yarn roller for a false twist texturing machine disclosed in the authorized Chinese patent CN215710587U can limit the yarn through the use of structures such as a fixed column, a winding roller, a fixed disk, a connecting plate, a fixed rod, a cross bar, a fixed shell, a protective pad, a line roller fixing plate, a mounting hole, a first limiting hole, a U-shaped rod, a pull disk, a pull rod, a second limiting hole, a second telescopic spring, a fixed ring, a vertical plate, a fixed frame, a ceramic ring, a fixed frame and a first telescopic spring. At the same time, the wear on the yarn is reduced. In addition, it can also make the yarn outlet direction change more convenient. In addition, the fixed shell plays a role in protecting the U-shaped rod.

[0004] However, when the yarn roller used in the false twist texturing machine in the above-mentioned cited document is in use, the surface of the yarn roller will gradually deform during the long-term extrusion process, resulting in uneven tension of the yarn. The strength and quality of the yarn will also be affected, thereby affecting the quality and efficiency of the entire yarn production. At this time, the yarn roller needs to be replaced. However, since the yarn roller is fixedly connected to the frame, the disassembly and assembly of the yarn roller is more troublesome. The entire frame needs to be disassembled to replace the yarn roller, which is not only time-consuming and labor-intensive, but also easily causes damage to the machine, resulting in the need to improve the disassembly and assembly effect of the existing yarn roller.

[0029] Through the mutual cooperation between the fixed shell 2, the fixed column 3, the yarn roller 4 and the quick disassembly and assembly mechanism 500 on the fixed frame 1, a function that facilitates the quick disassembly and assembly of the yarn roller 4 can be provided, making the disassembly and assembly of the yarn roller 4 more convenient, and the yarn roller 4 can be replaced without disassembling the entire frame, which greatly improves the efficiency and quality of yarn production, avoids production quality problems caused by deformation of the yarn roller 4, and thus effectively improves the disassembly and assembly effect of the existing yarn roller.

[0030] In this embodiment, the quick disassembly mechanism 500 is a structure for facilitating quick disassembly of the yarn roller 4.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the quick disassembly mechanism 500 includes a driving assembly installed on one side of the fixing frame 1 and two adjustment boxes 502 respectively fixedly installed on one side of the fixing frame 1, both sides of the driving assembly are connected to a gear transmission assembly located in the adjustment box 502 and a meshing fastening assembly connected to the outside of the gear transmission assembly, and one side of the meshing fastening assembly is connected to an auxiliary moving assembly connected to the adjustment box 502;

[0032] The driving assembly drives the gear transmission assembly to rotate, so as to drive the meshing and fastening assembly to move on the auxiliary moving assembly, so as to limit the movement of the fixing column 3 .

[0033] It should be noted that the driving assembly includes a dual-axis servo motor 5011, a No. 1 rotating rod 5012 and a bearing support 5013; one side of the dual-axis servo motor 5011 is fixedly mounted on one side of the fixed frame 1, one end of the No. 1 rotating rod 5012 is fixedly connected to the output shaft of the dual-axis servo motor 5011, and the other end passes through the adjustment box 502 and is connected to the gear transmission assembly, so as to be able to stably drive the gear transmission assembly to rotate.

[0034] It can be understood that one side of the bearing support 5013 is fixedly connected to one side of the fixing frame 1, and the inner side of the bearing support 5013 is rotatably connected to the outer side of the No. 1 rotating rod 5012 through a bearing, in order to more stably support the rotation of the No. 1 rotating rod 5012.

[0035] In addition, the gear transmission assembly includes a driving bevel gear 5031, a driven bevel gear 5032 and a second rotating rod 5033; one side of the driving bevel gear 5031 is fixedly connected to an end of the first rotating rod 5012 away from the dual-axis servo motor 5011, and both ends of the second rotating rod 5033 are rotatably connected to the inner wall of the adjustment box 502 through bearings;

[0036] The dual-axis servo motor 5011 drives the first rotating rod 5012 to rotate, so as to drive the driven bevel gear 5032 meshed with the driving bevel gear 5031 to rotate, and the second rotating rod 5033 rotates accordingly, so as to stably drive the meshing fastening component to move.

[0037] In this embodiment, the meshing and fastening assembly includes a spur gear 5041, a tooth plate 5042 and an insert block 5043; the inner side of the spur gear 5041 is fixedly connected to the outer side of the second rotating rod 5033, one side of the spur gear 5041 is meshed with one side of the tooth plate 5042, and one side of the tooth plate 5042 passes through the adjustment box 502 and the fixed shell 2 in sequence and extends to one side of the insert block 5043 and is fixedly connected to the insert block 5043;
