Background technique

False twist texturing machine is a kind of textile machinery that can process untwisted yarns such as nylon, polyester, polypropylene, etc. into elastic yarns with certain elasticity through false twist deformation.

Covered yarn is a fancy yarn. In the prior art, the raw material of the outer covering yarn of the covered yarn is usually untwisted yarn, and the untwisted yarn is processed by a false twist texturing machine to obtain elastic yarn, and the obtained elastic yarn is packaged into large-capacity packages, and then obtained by winding Covered yarn reels with small capacity for processing covered yarns. Due to the small capacity of the double-sided bobbins used in the covering yarn reel, the covering yarn reel needs to be replaced frequently when a roll of covering yarn is produced. After each replacement of the covering yarn reel, a joint will be produced in the covering yarn. After changing the outer covering yarn reel several times, the covering yarn will produce multiple joints, which affects the quality of the covering yarn.

detailed description

The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

Example 1

As shown in Figure 1 and Figure 2, a false twist textured fancy yarn machine includes the following structures:

The false-twisting texturing device 1 is used for false-twisting and texturing the original yarn 2, and the elastic yarn obtained after the false-twisting texturing is the covering yarn 6. Under the traction of the traction mechanism of the false twist deformation device 1, the raw silk 2 is processed into elastic yarn mainly through its deformation heating box, false twister and other mechanisms, and the elastic yarn enters the fancy yarn device as the outer covering yarn 6 It is used to process covered yarn in the future; among them, the deformation heat box of the false twist deformation device 1 is used to heat the raw silk 2 to make it in a plasticized state and reduce its tensile deformation ability; the false twister generates mechanical twisting stress for False-twist deformation treatment is performed on the heated and plasticized raw yarn, and the elastic yarn obtained after the false-twist deformation treatment is used as the outer covering yarn 6, and the outer covering yarn 6 directly enters the fancy yarn device 4 for processing the package without going through the package and winding. Cover yarn.

The fancy yarn device 4 includes a suspending body 42, which is suspended above the suspending support body 41 and does not contact with the suspending supporting body 41, leaving space for the covering yarn 6 to cover the core yarn 7. The suspending body 42 is suspended between the suspending support body 41 in the form of electromagnetic levitation, and its internal structure and specific driving principle are consistent with those in the prior art, so they are not shown in the figure. The suspension is used to support the core yarn reel 44 . When in use, the core yarn reel 44 is placed on the suspension 42 so that the core yarn 7 can be drawn out from above the suspension 42 .

Mounting frame, suspension body 42 is provided with mounting frame 43, and tensioner 47 is installed on this mounting frame 43, so that when the core yarn 7 that core yarn reel 44 outputs passes here, draft, make it be in tension. state, the mounting frame 43 is mounted on the outside of the core yarn drum 44 .

The rotating part is installed in the supporting part (not shown in the figure) and rotates relative to the supporting part driven by the driving mechanism. The support member can be a support frame or other structures, and further, it can be configured as a shared support frame of the rotating part and the suspension support body 41, that is, the suspension support body 41 is arranged under the support frame, and the rotation part is arranged on the support frame. Above the frame, a space for suspending the suspending body 42 is formed between the rotating part and the suspending supporting body 41 .

The rotating part is a revolving body formed by an inverted T-shaped main body 45 in longitudinal section and an annular protrusion 46 connected to the lower part of the main body 45. The upper part of the main body 45 penetrates into the bearing, and the bearing can be fixed on the support. Parts, so that the rotating part is driven by the drive mechanism to rotate relative to the supporting part. A central hole 49 runs through the central axis of the main body 45, and a guide wire hole 461 is provided on the annular protrusion 46 along the radial direction of the rotating component. Also be provided with balance hole 462 on the top, balance hole 462 extends along the radial direction of annular protruding portion 46, and radially oppositely sets with guide wire hole 461, because guide wire hole 461 will drive outer covering yarn 6 to move when working, therefore for To maintain the overall dynamic balance of the rotating parts, a balance hole 462 corresponding to the guide wire hole 461 is provided, and the diameter of the balance hole 462 is not larger than the guide wire hole 461 . In this way, the rotating member can stably rotate at high speed. The wire guide hole 461 is used to guide the outer covering yarn 6 to pass through so that the outer covering yarn 6 covers the core yarn 7, and the central hole 49 is used to output the covering yarn formed after covering. The rotating part is located above the mounting frame 43 , and forms an interval space between the mounting frame 43 and the covering yarn 6 for covering the core yarn 7 . When the rotating part rotates under the drive of the drive mechanism, it drives the outer covering yarn 6 to rotate around the suspension body 42, the core yarn reel 44 and the outside of the mounting frame 43, so that the outer covering yarn 6 penetrated by the guide wire hole 461 can be Covering core yarn 7.

The core yarn bobbin 44 is placed on the suspending body 42 so as to be suspended in the air, for example by means of electromagnetic levitation. After the core yarn 7 is drawn by the tensioner 47, it is wound on the winding mechanism, so that the core yarn 7 is unwound driven by it. The outer covering yarn 6 needs to pass through the guide wire hole 461 of the rotating part to merge with the core yarn 7, so as to facilitate subsequent covering.

Step 3, drive the rotating part to rotate, so that it drives the outer covering yarn 6 penetrated through the guide wire hole 461 to cover the core yarn 7, and the formed covering yarn is output through the central hole 49 of the rotating part.

In this step, the core yarn 7 is drafted by the tensioner 47, so that the core yarn 7 is kept under tension for covering. Drive the rotating part to rotate through the driving mechanism, so that the rotating part drives the outer covering yarn 6 penetrated by the guide wire hole 461 of the rotating part to cover the core yarn 7 to form a covering yarn, and the covering yarn is output from the central hole 49 of the rotating part .

Step 4, the winding mechanism 48 winds the covered yarn output from the center hole 49 .

In this step, the winding mechanism 48 winds the covering yarn formed by covering the core yarn 7 with the outer covering yarn 6 for collection.
