Description

Technical Field

[0001] The utility model relates to the technical field of false twist texturing machines, in particular to a winding tension regulating mechanism of a false twist texturing machine. Background Art

[0002] The false twist texturing machine is a new type of stretch yarn processing machinery, which mainly includes three continuous basic processing processes: twisting, heat setting and untwisting. The silk thread is highly twisted above the softening temperature to produce plastic non-rotatable twisting deformation, and the torsional stress generated during twisting is eliminated by heating. The silk thread is shaped after cooling, and the number of twists of the silk thread after untwisting is zero, so that the silk thread has elasticity and stretchability.

[0003] In order to adjust the winding tension, for example, a Chinese utility model patent with a publication number of CN210393246U provides a winding tension adjusting device for a false twist texturing machine, which relates to the field of false twist texturing machines, including a frame, a swing frame hinged on the frame, a winding shaft hinged at one end of the swing frame, a driving roller corresponding to the winding shaft, and an adjusting mechanism for adjusting the winding pressure, wherein both ends of the driving roller are hinged to the frame, and the adjusting mechanism includes a screw rod, a copper sleeve threadedly engaged with the screw rod, and a driving assembly for driving the screw rod to rotate. In the winding tension adjusting device for the false twist texturing machine, when winding is performed, the servo motor of the adjusting mechanism rotates, and the servo motor drives the screw rod to rotate, so that the copper sleeve on the screw rod can move on the screw rod, and the copper sleeve drives the swing frame to rotate, thereby generating a winding pressure between the winding shaft at the other end of the swing frame and the driving roller to achieve winding, and during the winding process, the winding pressure is adjusted by rotating the screw rod, and the accuracy of the screw rod is very high, so the winding pressure can be controlled more accurately.

[0004] However, there are still some problems. Although it can be adjusted by rotating the screw rod, and the screw rod has high accuracy and can control the winding pressure more accurately, the servo motor has a certain gravity, and the servo motor is hinged to the fixed rod through the first bearing seat. Therefore, when adjusting, the movement of the servo motor will cause the gravity to change, and there is a problem of poor stability. Therefore, a winding tension adjustment mechanism of a false twist texturing machine is proposed to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 and Figure 3 The winding tension adjustment mechanism of a false twist texturing machine in this embodiment includes two fixed frames 1, a driving roller 2 is rotatably connected between the two fixed frames 1, and a fixed bearing is fixed on the opposite side of the two fixed frames 1. The interior of the fixed bearing is fixed to the driving roller 2. The fixed bearing can effectively improve the rotation stability of the driving roller 2. The opposite side of the two fixed frames 1 is hinged with a connecting plate 4, and the interior of the connecting plate 4 is rotatably connected to a winding shaft 3 slidably connected to the fixed frame 1. The winding shaft 3 and the left and right sides of the adjusting rod 5 are rotatably connected with rollers 6. The winding shaft 3 is located on the front side of the driving roller 2, and a rolling groove adapted to the roller 6 is opened inside the fixed frame 1. The rolling groove is an arc groove. The roller 6 is set to make the winding shaft 3 and the adjusting rod 5 more stable when moving.

[0023] In addition, the two connecting plates 4 are internally rotatably connected with an adjusting rod 5 which is slidably connected to the fixing frame 1, a supporting plate 7 is fixed between the two fixing frames 1, and a pushing component 8 is fixed on the top of the supporting plate 7, and the pushing component 8 is used to push the adjusting rod 5 to move.

[0024] In general, when the adjusting rod 5 moves, the connecting plate 4 can drive the winding shaft 3 to move in an arc shape, thereby completing the adjustment of the winding tension.

[0025] See also Figure 2 In order to make the whole more stable, the pushing assembly 8 in this embodiment includes a driving motor 801, a driving rod 802, a limiting rod 803, a pushing rod 804, and two telescopic blocks 805. The top of the support plate 7 is fixed to the driving motor 801, the output shaft of the driving motor 801 is fixed to the driving rod 802, the front of the driving motor 801 is fixed to the limiting rod 803, the outer surface of the driving rod 802 is threadedly connected to the pushing rod 804, the outer surface of the driving rod 802 is fixed with a threaded bar, the interior of the pushing rod 804 is provided with a threaded hole matched with the threaded bar, the outer surface of the limiting rod 803 is slidably connected to the pushing rod 804, and the setting of the limiting rod 803 limits the rotation of the pushing rod 804, so that when the driving rod 802 rotates, the pushing rod 804 will move due to the extrusion of the thread.

[0026] Furthermore, the outer surface of the push rod 804 is slidably connected to the telescopic block 805, so that the telescopic block 805 can move up and down on the outer surface of the push rod 804, thereby ensuring the stability of the connection. The telescopic block 805 includes an extension block slidably connected to the push rod 804, and the extension block is internally slidably connected to an extension plate slidably connected to the fixed frame 1.

The interiors of the two telescopic blocks 805 are fixed to the adjusting rod 5.

[0027] In general, when the adjusting rod 5 is pushed to perform an arc motion, the telescopic block 805 will move on the outer surface of the pushing rod 804, thereby ensuring the stability of the pushing, and the set sliding block further limits the moving direction of the telescopic block 805, thereby making the whole more stable.

[0028] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0029] The working principle of the above embodiment is:

[0030] When the winding tension needs to be adjusted, the driving motor 801 is started to make the driving rod 802 rotate, so that the pushing rod 804 whose rotation is restricted by the limiting rod 803 is moved due to the extrusion of the thread, and then the telescopic block 805 is pushed to move, so that the telescopic block 805 is slidably connected to the fixed frame 1 and the moving direction is restricted, so that the telescopic block 805 pushes the adjusting rod 5 toward the front, so that the connecting plate 4 rotates along the hinge point, so as to adjust the position of the yarn winding shaft 3 and complete the adjustment of the winding tension. The driving motor 801 is firmly fixed on the supporting plate 7 without moving, thereby effectively ensuring the stability of operation, making the whole more practical.
