Technical Field

[0001] The utility model relates to the technical field of false twisting machines, in particular to a novel silk false twisting machine. Background Technique

[0002] False twisters are widely used in the textile industry. The working principle of a false twister is as follows: Since both ends of the silk thread are controlled, when twisting is applied between the two ends of the silk thread, equal amounts of twists with opposite directions can be generated on the silk thread. This can increase the strength of the section with the same twist direction as the designed twist direction of the silk thread, and at the same time, it will cause untwisting or reverse twisting of the other section of the silk thread. Currently, the commonly used false twisters mainly include rotor type, friction disk type, rubber ring type, and ring rubbing type, etc.

[0003] For example, Chinese Patent (Publication No.: CN219689971U) discloses a false twisting device for roving frames, including a device main body. A base is installed at the bottom end of the device main body, and three rotating shafts are installed at the top end of the base. Friction disks are installed on the rotating shafts; through the action of an electric telescopic rod, the slider can move in the top groove, and then drive the moving plate to move. This method is simple and convenient to operate, and can clean the friction disks better.

[0004] The above technical solution also has the following defects. Although this false twisting device for roving frames is simple and convenient to operate and can clean the friction disks better, during actual use, the friction disks will be worn during use and need to be replaced when they reach a certain degree. This device is not convenient for single replacement of the friction disks, which is not conducive to improving work efficiency and is not convenient for cost saving. Based on this, a novel silk false twisting machine is proposed to solve the above problems. Content of the Utility Model

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 , a new type of filament false twister in this embodiment includes a base 1, three rotating shafts 2 are rotatably connected to the base 1, a fixing mechanism 3 is provided on the rotating shaft 2, and a friction disc main body 4 is provided on the fixing mechanism 3.

[0025] It should be noted that by operating the fixing mechanism 3, the convenient fixing or replacement of the friction disc main body 4 can be realized, further reducing the maintenance cost and the labor intensity of the staff.

[0026] Please refer to Figures 1-4, To facilitate the fixing or replacement of the friction disc body 4, the fixing mechanism 3 in this embodiment includes three fixing blocks 301 fixed on the outer surface of the rotating shaft 2. An adjusting component is provided on the fixing block 301, and a limiting component is provided on the fixing block 301. The fixing mechanism 3 further includes a moving component. The adjusting component includes two adjusting slots 302 opened on the fixing block 301. The cross-section of the adjusting slot 302 is convex. A sealing ring is fixed on the inner wall of the adjusting slot 302. The inner wall of the sealing ring fits with the outer surface of the worm 303, so that there will be many fine hairs on the wire that will not fall into the interior of the adjusting slot 302, avoiding affecting the operation of the device. The inner bottom wall of the adjusting slot 302 is rotatably connected to a worm 303 that penetrates to the outside of the fixing block 301. A handle 304 is fixed on the top of the worm 303. A worm gear 305 is engaged with the outer surface of the worm 303. By rotating the handle 304 to drive the worm 303 to rotate, the worm gear 305 can be driven to rotate through the meshing force, and then the position of the moving component can be adjusted.

[0027] Among them, the moving component includes a bidirectional screw 306 rotatably connected between the left and right sides of the inner cavity of the adjusting slot 302 through bearings at both ends. The middle of the outer surface of the bidirectional screw 306 is fixed to the inner wall of the axis of the worm gear 305, which is convenient for the worm gear 305 to drive the bidirectional screw 306 to rotate when rotating, and then drive the moving block 307 to move. Two moving blocks 307 are threadedly connected to the outer surface of the bidirectional screw 306. A moving rod 308 is fixed to the bottom of the moving block 307. The opposite sides of the two moving rods 308 are in contact with the opposite sides of the two adjusting blocks 314, which is convenient for squeezing the adjusting block 314 and driving it to move. The cross-section of the moving rod 308 is L-shaped. The limiting component includes two adjusting holes 309 opened on the left and right sides of the fixing block 301. A limiting block 310 is slidably connected to the inner wall of the adjusting hole 309. The cross-sections of the adjusting hole 309 and the limiting block 310 are both T-shaped, so that the limiting block 310 can move more stably. Connecting rods 311 are fixed to the opposite sides of the two limiting blocks 310. Adjusting rods 312 are fixed to the opposite sides of the two connecting rods 311. A spring 313 is sleeved on the outer surface of the connecting rod 311, which is convenient for playing a certain buffering role. Adjusting blocks 314 are fixed to the opposite sides of the two adjusting rods 312. The limiting component further includes limiting slots 317 opened on the left and right sides of the inner side wall of the friction disc body 4. The limiting block 310 is slidably connected to the limiting slot 317. A guiding block 315 is fixed to the bottom of the adjusting rod 312. By driving the moving block 307 and the moving rod 308 to move through the bidirectional screw 306, the adjusting block 314 and the adjusting rod 312 can be driven to move, and the limiting block 310 can be promoted to move into the limiting slot 317, thereby realizing the convenient fixing of the friction disc body 4.

[0028] Meanwhile, two guiding grooves 316 opened on the fixing block 301 communicate with the inner bottom wall of the adjusting groove 302. The guiding grooves 316 are slidably connected to the guiding blocks 315. The cross-sections of the guiding grooves 316 and the guiding blocks 315 are both convex, facilitating the guiding block 315 to move along the inner wall of the guiding groove 316 following the adjusting rod 312 when the adjusting rod 312 moves, so that the adjusting rod 312 can move more stably.

[0029] It should be noted that through the cooperation of the adjusting assembly, the limiting assembly and the moving assembly, it is more convenient and fast to replace the friction disc main body 4 when needed, further improving the work efficiency.

[0030] The working principle of the above embodiment is as follows:

[0031] When the friction disc main body 4 needs to be installed, first move the friction disc main body 4 downward along the rotating shaft 2 until the friction disc main body 4 and the fixing block 301 fixing it are on the same horizontal line. Then, rotate the handle 304 to drive the worm 303 to rotate, so that the worm gear 305 and the bidirectional screw 306 can be driven to rotate through the meshing force. Then, the two moving blocks 307 on the outer surface of the bidirectional screw 306 can drive the two moving rods 308 to move away from each other. Since the two moving rods 308 move away from each other, they will gradually squeeze the two adjusting blocks 314 and the adjusting rod 312. Furthermore, the two connecting rods 311 can be driven to squeeze the two limiting blocks 310 to move away from each other along the adjusting holes 309 until the limiting blocks 310 move into the limiting grooves 317, thus realizing the convenient fixing of the friction disc main body 4, and realizing the convenient assembly of the friction disc. At the same time, since the spring 313 will generate elastic force when the adjusting block 314 is squeezed and moved, it can buffer the pressure received by the adjusting block 314 to avoid direct rigid contact between the limiting block 310 and the limiting groove 317. Operating according to the above principle can also realize the convenient replacement of the friction disc. When the friction ring is worn, only the friction ring needs to be replaced, and there is no need to replace the whole friction disc, reducing the maintenance cost and further improving the work efficiency.

[0032] It can be understood that the control mode of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present invention is mainly used to protect mechanical devices, so the control mode and circuit connection of the present invention will not be explained in detail.
