[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 6 As shown, this embodiment discloses a false twist device, including a base 1 and multiple false twist units 2. There are three false twist units 2, and the included angle of the three false twist units 2 is 120°. The base 1 has multiple mounting holes 11, and the false twist units 2 pass through the corresponding mounting holes 11. Each false twist unit 2 includes a false twist shaft 21, and a bearing 22 is fixed to the outside of the false twist shaft 21. The bearing 22 is located inside the mounting hole 11, and the outer wall of the bearing 22 is sealed to the inner wall of the mounting hole 11. The bearing 22 includes inner and outer rings. The inner ring is fixed to the false twist shaft 21, and the outer wall of the outer ring is sealed to the mounting hole 11. A gear 25 is provided at the lower end of the false twist shaft 21. The gear 25 is located below the base 1. The gears 25 of the three false twist units 2 can mesh with a drive gear (not shown in the figure). The drive gear drives the three false twist shafts 21 to rotate synchronously, thereby realizing the false twist function.

[0026] like Figure 3As shown, the bearing 22 has an annular groove 23 on its side, and an oil inlet hole 24 is provided in the annular groove 23. The base 1 has an oil injection hole 12 corresponding to the false twist unit 2 on its side. The oil injection hole 12 is connected to the mounting hole 11 and one end is located in the annular groove 23. The other end of the oil injection hole 12 is fixed with an oil nozzle 3. The oil nozzle 3 is a standard M6 grease nipple, which is existing technology. The oil nozzle 3 and the oil injection hole 12 are connected by threads. By setting an oil injection hole 12 connected to the mounting hole 11 in the base 1, and setting a corresponding oil nozzle 3 at the opening of the oil injection hole 12 on the outer wall of the base 1, the bearing 22 can be lubricated without disassembling the false twist unit 2, which is convenient for the maintenance of the bearing 22 and easy to operate. When lubricating, lubricating oil is injected from the oil nozzle 3 through the oil gun. The lubricating oil enters the annular groove 23 after passing through the oil injection hole 12, and then enters the bearing 22 from the oil inlet hole 24, thus achieving the lubrication of the bearing 22. The bearing 22 is existing technology, and its specific structure will not be described in detail in this specification.

[0027] The base 1 is connected to a top plate 4 at its upper part, and the lower part of the top plate 4 abuts against the upper part of the bearing 22. The base 1 is connected to a bottom support 5 at its lower part, and the upper part of the bottom support 5 abuts against the lower part of the bearing 22. By setting the top plate 4 and the bottom support 5, the false twist unit 2 can be fixed. The top plate 4 is fixed to the base 1 by screws 8, and the bottom support 5 is fixed to the base 1 by bolts 6. By setting the bolts 6 and screws 8, the bottom support 5 and the top plate 4 can be detached, which is convenient for disassembly and maintenance of the false twist unit 2 and is easy to operate.

[0028] The top plate 4 includes an annular sleeve 41 corresponding to the false twist unit 2. The annular sleeve 41 has a positioning hole 42 inside. The false twist unit 2 passes through the positioning hole 42. The upper part of the bearing 22 abuts against the lower part of the annular sleeve 41, and the upper part of the outer ring of the bearing 22 abuts against the lower part of the annular sleeve 41. A positioning sleeve 26 is fixed on the outside of the false twist shaft 21. The outer wall of the positioning sleeve 26 is clearance-fitted with the inner wall of the positioning hole 42. Through the cooperation between the positioning hole 42 and the positioning sleeve 26, the top plate 4 can be installed and positioned, which facilitates installation.

[0029] The top plate 4 is provided with a second limiting platform 16 on its upper part. The top plate 4 includes a limiting groove 43. The second limiting platform 16 is inserted into the limiting groove 43 for limiting. Through the cooperation of the second limiting platform 16 and the limiting groove 43, the top plate 4 can be further installed and positioned, which facilitates the installation of the top plate 4.

[0030] The base 5 includes a connecting piece 51 corresponding to the false twist unit 2. The upper part of the connecting piece 51 abuts against the lower part of the bearing 22 of the corresponding false twist unit 2. The bottom of the base 1 is provided with a first limiting platform 15. The side of the base 5 is provided with a notch 52. The first limiting platform 15 is inserted into the notch 52 for limiting. Through the cooperation of the first limiting platform 15 and the notch 52, the base 5 can not only be installed and positioned, but also rotate relative to the bolt 6 when it is turned, which is convenient for the assembly and disassembly of the base 5.

[0031] The base 1 includes a threaded groove 13 and a clearance groove 14. The bolt 6 passes through the clearance groove 14 and is inserted into the threaded groove 13 for fixation. A spring 7 is sleeved on the outside of the bolt 6. The spring 7 is located in the clearance groove 14. The two ends of the spring 7 abut against the upper part of the base 5 and the upper surface of the clearance groove 14, respectively. When the bolt 6 is tightened, the spring 7 is in a compressed state. The false twist unit 2 will generate vibration during operation. By setting the spring 7, an elastic force can always be applied to the bolt 6, thereby effectively preventing the bolt 6 from loosening and improving the reliability of the structure.
