In this embodiment, the rotation centers of the first shaft segment 551 and the second shaft segment 552 of the second shaft 55 are not on the same straight line, which is equivalent to that the first shaft segment 551 and the second shaft segment 552 are eccentrically disposed, and the pinch roller 53 is mounted on the second shaft segment 552, so that when the first shaft segment 551 rotates, the distance between the pinch roller 53 and the driving roller 52 will change, and the pinch roller 53 and the driving roller 52 can be pressed or loosened by using the change of the distance, i.e. the pinch roller 53 and the driving roller 52 can be pressed or loosened by using the eccentric principle, and in actual operation, the adjustment can be quickly realized by only pulling the deflector rod 56, which is very convenient to operate, and the whole traction roller structure is also simpler.

In this embodiment, the rotation direction of the lever 56 has a first direction S1 and a second direction S2 opposite to the first direction S1, when the lever 56 rotates in the first direction S1, the pinch roller 53 rotates eccentrically toward the driving roller 52, and when the lever 56 rotates in the second direction S2, the pinch roller 53 rotates eccentrically away from the driving roller 52. Therefore, when the user needs to release the pressing wheel 53, the user needs to dial the shift lever 56 to rotate in the second direction S2, and when the user releases the shift lever 56, the shift lever 56 returns to the first direction S1 under the action of the tension spring 57.

In order to keep the pinch roller 53 and the driving roller 52 in a separated state even when the user is in a loose state, in this embodiment, a limiting block 58 is provided, that is, when the driving lever 56 rotates to a certain angle along the second direction S2, and when the driving lever 56 and the tension spring 57 are at a critical point, if the driving lever 56 continues to rotate in the second direction S2, the driving lever 56 is released, the driving lever 56 does not return to the first direction S1, but continues to rotate in the second direction S2 until the driving roller is tightly contacted again, and the limiting block 58 is provided between the critical point and a range of the re-rotation position when the driving lever 56 rotates in the second direction S2, specifically, referring to fig. 8, the limiting block 58 is provided at the position, the driving lever 56 is stopped on the limiting block 58, and does not rotate in the first direction S1, and also does not rotate in the second direction S2, so that the pinch roller 53 and the driving roller 52 can be mutually separated under the premise of releasing the driving lever 56.

Because pinch roller 53 is close to initiative running roller 52, pinch roller 53 itself is also taking place to rotate, in order to reduce the friction between pinch roller 53 and the second shaft section 552, be equipped with bearing 531 between pinch roller 53 and the second pivot 55, the both ends of pinch roller 53 are equipped with the bearing groove at least one end, the bearing is installed in the bearing groove, after setting up the bearing, can effectively reduce the friction between pinch roller 53 and the second shaft section 552. In addition, in order to reduce the weight of the pressing wheel 53, a plurality of material stealing holes are formed in the pressing wheel 53.

The whole process flow of chemical fiber texturing comprises the following steps: the yarn is pulled out from the yarn winding drum 12, passes through the second tension sensor 14, passes through the yarn dividing hole 151 on the yarn dividing bent 15, then passes through the movable hook 13, the yarn collecting plate 16, the first roller 61, the second roller 62, the yarn pressing plate 18, the first traction roller 501, passes through the deformation assembly, mainly passes through the heating box 21 and the cooling box 22, then passes through the second traction roller 502, the third traction roller 503, the yarn combing plate 35, the yarn dividing plate 34, the yarn arranging plate 32, the fourth traction roller 504 and the tension regulator 33 in sequence, and finally is distributed to the winding unit 30.

While the invention has been described in terms of embodiments, it will be appreciated by those skilled in the art that the invention is not limited thereto but rather includes the drawings and the description of the embodiments above. Any modifications which do not depart from the functional and structural principles of the present invention are intended to be included within the scope of the appended claims.
