Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of textiles, and particularly relates to a twistable false twist device for textile filaments. BACKGROUND

[0002] It is known from the prior art that CN103649392B, CN101629342A, CN101082142A disclose a false twist machine of this kind, which is used in the textile process to produce a false twist on a multi-filament filament running in order to crimp it. On the false twist machine there are three driven friction spindles, on which a plurality of friction discs are arranged. The friction spindles are arranged in a triangle so that the friction discs overlap each other in the center of the triangle. The filaments run in the center on the periphery of the friction discs through the overlap area, so that each friction disc transmits a torque to the filament, which causes a twist of the filament.

[0003] The filaments are twisted as they pass through the overlap area of the friction discs, so that the area of the mutual overlap of the friction discs in the center of the triangle affects the false twist effect. However, the friction spindles (also called spindle shafts) are relatively fixed on the machine base to form a stable triangle, so that the mutual overlap area of the friction discs on the spindle shafts is also limited and cannot be increased or decreased. SUMMARY

[0018] Further, the control handle further comprises a pinching part slidably arranged in the fixed part, the pinching part is in a U shape, the elastic buckle further has an unlocking part between the base and the distal end, the unlocking part is located on the sliding path of the pinching part, the unlocking part is a protrusion, when the pinching part slides away from the second driven shaft, the unlocking part is extruded by the pinching part to deform the elastic buckle and its distal end inwardly to disengage from the slot, thereby releasing the state keeping of the second driven shaft in the first position.

[0019] Further, the housing is further provided with a supporting assembly, the supporting assembly comprises:

[0020] A connecting sleeve is arranged outside the driving shaft;

[0021] An elastic connecting sheet is connected with the connecting sleeve at one end;

[0050] The adjustable transmission assembly 400 makes the rotation shafts of the spindle assemblies 300 and the driving shafts 110 on the surface of the base 100 form a dislocation state, and at the same time, the distance between the rotation shafts of the spindle assemblies 300 and the driving shafts 110 on the surface of the base 100 can be adjusted, that is, the spindle assemblies 300 can change the distance relative to the driving shafts 110 through the adjustable transmission assembly 400, so that the distance between the rotation shafts of the three spindle assemblies 300 is changed, and then the superimposed area of the friction discs 320 can be changed.

[0052] In combination with Figure 2 The shell 410 is provided with a strip-shaped hole 411 to accommodate the extension of the driving shaft 110 into the shell 410, and in order to meet the change of the distance between the spindle assembly 300 and the driving shaft 110, the shell 410 can be controlled to move relative to the base 100, so that the position of the driving shaft 110 in the strip-shaped hole 411 changes, and the distance between the driving shaft 110 and the first driven shaft 420 changes indirectly.

[0053] In order to ensure the stability of the driving effect, the transmission belt 440 is a toothed synchronous belt, and the matching surfaces of the first driven shaft 420, the second driven shaft 430 and the driving shaft 110 are all toothed surfaces.

[0054] Further, in order to meet the stable transmission and adjustable purpose of the adjustable transmission assembly 400, the second driven shaft 430 has two working positions in the shell 410, in the first position, the shaft distance between the second driven shaft 430 and the first driven shaft 420 is large, so as to tighten the transmission belt 440, thereby ensuring the good meshing of the transmission belt 440 with the driving shaft 110 located in the middle; in the second position, the shaft distance between the second driven shaft 430 and the first driven shaft 420 is smaller than that in the first position, the transmission belt 440 changes from the tightened state to the relaxed state, so that the driving shaft 110 and the transmission belt 440 are in a non-tight contact state, and the transmission belt 440 does not hinder the position change of the driving shaft 110 relative to the shell 410.

[0055] Figure 3 The structure of the second driven shaft 430 is shown, the second driven shaft 430 includes a shaft rod 431 and an engaging part 432 rotatably arranged outside the shaft rod 431, and the engaging part 432 is matched with the transmission belt 440.

The control handle 450 includes a fixed part 451 and a pinching part 452, the fixed part 451 is U-shaped and fixedly connected to both ends of the shaft rod 431, and the pinching part 452 is also U-shaped and slidingly arranged on the fixed part 451; the two extended arms of the fixed part 451 have a notch 4511 and a elastic buckle 4512 arranged in the notch 4511, the elastic buckle 4512 has a base connected with the fixed part 451 and a distal end away from the base, the distal end of the elastic buckle 4512 protrudes outward from the outer side arm of the fixed part 451, and the distal end of the elastic buckle 4512 is perpendicular to the outer side arm of the fixed part 451, and the inner wall of the shell 410 is provided with a groove 411 matched with the distal end of the elastic buckle 4512, when the distal end of the elastic buckle 4512 is embedded in the groove 411, the second driven shaft 430 is fixed in the first position.

[0057] In combination Figure 3 The elastic buckle 4512 also has an unlocking part 4513 between the base and the distal end, the unlocking part 4513 is located in the sliding path of the pinching part 452, and the unlocking part 4513 is a protruding structure, when the pinching part 452 slides away from the second driven shaft 430, the pinching part 452 contacts the unlocking part 4513 and extrudes the unlocking part 4513 inward, so that the elastic buckle 4512 deforms inward as a whole, the distal end of the elastic buckle 4512 is separated from the groove 411 on the inner wall of the shell 410, and the fixed state of the second driven shaft 430 is released, so that the second driven shaft 430 can be transformed from the first position to the second position.

[0058] It should be noted that the second driven shaft 430 in the second position can be fixed or movable relative to the shell 410, and in this application, only the change in the tension state of the transmission belt 440 during the transformation of the second driven shaft 430 from the first position to the second position is required.
