Description

Technical Field

[0001] The invention relates to the technical field of polyester core-spun yarns, and in particular to a continuous composite bundling unit based on polyester core-spun yarns, a preparation system and a method. Background Art

[0002] Core-spun yarn generally uses strong and elastic synthetic fibers as the core yarn, and is covered with more flexible yarns such as cotton and wool. Polyester core-spun yarn often uses polyester yarn as the core yarn of the bundle.

[0003] The polyester core-spun yarn is usually gathered and bundled by a bunching ring and a bunching wheel. At the same time, during the bundling process, the spiral grooves on the winding wheel will cause the two kinds of wires to be twisted and rotated when the rollers are collected, so that the polyester wires and the yarns are twisted together under the premise of bundling to realize the processing of single bundle of polyester core-spun yarn. During this period, the yarn will unwind due to the twisting friction processing during the twisting and rotation process, which makes the wool yarns on its surface easy to twist and fall off, and then the yarn lacks the wrapping amount of the polyester wire after it is finally produced, which affects the final quality of the polyester core-spun yarn. In addition, in the production process of traditional polyester core-spun yarn bundles, the wool yarns on the surface of the yarn are often too concentrated when the yarn is bundled, which makes it difficult to spread out the bundle wrapping of the polyester wire.

[0019] Beneficial Effects

[0020] The present invention provides a continuous composite bundling unit based on polyester core-spun yarn, a preparation system and a method thereof. Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The continuous composite bundling unit, preparation system and method based on polyester core-spun yarn are provided with a wet wire box. When the wire bundle is about to enter the twisting frame for twisting, it will pass through the inside of the wet wire box through the first wire inlet and the first wire outlet. The wire bundle inside the wet wire box will be wetted by the spray of the mist nozzle at the bottom of the liquid outlet pipe under the pump driving force of the water pump. Before this, the wire bundle will be pre-collected by the first collecting coil, so that the yarn hair on the surface of the wire bundle in the wet wire box can be soaked so as to better adhere to the surface of the polyester silk. Then, when the soaked wire bundle enters the twisting frame through the first wire outlet for twisting, it can be better bonded together due to soaking and will not easily cause the hair on the yarn surface to unwind and fall off. Then, the polyester silk wrapping amount of the twisted wire bundle can be guaranteed, which is helpful for the final unit bundling quality of the polyester core-spun yarn, thereby solving the problem that the yarn is easy to unwind when twisting in the continuous composite bundling unit of the polyester core-spun yarn.

[0022] (2) The continuous composite bundling unit, preparation system and method based on polyester core-spun yarn are provided with a closing wheel. When the bundle passes through the closing wheel, the polyester yarn on the bundle will fall on the main line groove ring, and the flexible yarn will be located on the top of the polyester yarn. Under the downward pressure restriction of the guide pressure block on the closing wheel, the yarn hair on the upper side can be pressed down by the arc surface and spread out, and gradually scattered on the surface of the polyester yarn placed on the main line groove ring through the arc guidance, so that the two strands of yarn can be wrapped more evenly before the first collection coil is bundled. During this period, the telescopic power of the first electric telescopic rod can control the downward pressure of the guide pressure block, and the vertical limit block can roll and fit on the inner surface of the line groove of the closing wheel through the rolling ball, thereby solving the problem of uneven wrapping of the continuous composite bundling unit of polyester core-spun yarn when the yarn is bundled.

The two wire converging belts 201 and the opposite sides of the two final pressing rollers 202 converge the main and auxiliary wire materials of the core-spun yarn on one side and roll them and transmit them to the bundling mechanism 3 for bundling processing.

[0053] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0054] During operation, by setting up a wet wire box 309, when the wire harness is about to enter the twisting frame 3029 for twisting and twisting, it will pass through the inside of the wet wire box 309 through the first wire inlet 3010 and the first wire outlet 3011, and the wire harness inside the wet wire box 309 will be soaked by the spray of the mist nozzle 3017 at the bottom of the liquid outlet pipe 3016 under the pump driving force of the water pump 3015. Before this, the wire harness will be pre-collected by the first collecting coil 3013, so that the yarn hair on the surface of the wire harness in the wet wire box 309 can be soaked so as to better adhere to the surface of the polyester silk thread, so that the soaked wire harness can be better bonded together due to soaking when it enters the twisting frame 3029 through the first wire outlet 3011 for twisting and will not be easily damaged. The hair on the yarn surface is unwound and falls off, so that the polyester silk thread wrapping amount of the twisted wire bundle is guaranteed, which is helpful to the final unit bundling quality of the polyester silk core-spun yarn, thereby solving the problem that the continuous composite bundling unit of the polyester silk core-spun yarn is easy to unwind when twisting. During the period, the wire bundle in the wet wire box 309 will pass through the first wire passing wheel 3019 during the transmission process. The first wire passing wheel 3019 on one side will smooth the excess droplets on the surface of the wetted wire bundle through the scraper block 3027, so that the excess water on the surface of the wire bundle can be removed for later air drying, and the yarn hair wrapped on the surface of the wire bundle can be more closely fitted to the polyester silk thread through smoothing, so as to facilitate its bundling and twisting at the twisting frame 3029, and in the first Under the telescopic power of the second electric telescopic rod 3021, the sponge 3022 can be raised and lowered to squeeze the wire bundle passing through its top, so that the sponge 3022 can soak the bottom of the wire bundle due to the moisture collected at the mist nozzle 3017. The setting of the pull ring 3028 can make the scraper block 3027 at the bottom of the second connecting rod 3026 can be manually pulled up for threading operation, which helps to achieve the effect of soaking the whole body of the wire bundle. By setting the wire closing wheel 302, when the wire bundle passes through the wire closing wheel 302, the polyester thread on the wire bundle will fall on the main line groove ring 303, and the flexible yarn will be located on the top of the polyester thread, and under the downward pressure restriction of the guide pressing block 306 on the wire closing wheel 302, the yarn hair on the upper side can be pressed down by the arc surface and spread out, and pass through the arc. The two strands of yarn are gradually scattered on the surface of the polyester yarn placed on the main line groove ring 303, so that the two strands of yarn can be wrapped more evenly before being bundled in the first collecting coil 3013. During this period, the telescopic power of the first electric telescopic rod 305 can control the downward pressure of the guide pressing block 306, and the vertical limit block 307 can roll and fit on the inner surface of the line groove of the line-closing wheel 302 through the rolling ball 308, thereby solving the problem of uneven wrapping of the continuous composite bundling unit of the polyester core-spun yarn during yarn bundling. In addition, the main line roller 401 and the auxiliary line roller 402 will release the line to transmit the polyester yarn and yarn on the two strands of the bundle through the transition roller 403 to the line converging mechanism 2, and the line converging mechanism 2 transmits it to the line converging wheel 302 through the transmission and pressing of the converging dragon belt 201 and the final pressing roller 202.After the wire combining wheel 302 allows the wire harness to be better wrapped together, the wire harness will be soaked in the wet wire box 309 at the bundling mechanism 3 and twisted by the twisting frame 3029. During this period, when the first motor 3044 is started, it will drive the driven wheel 3042 to rotate through the driving wheel 3045, and then the rotation of the driven wheel 3042 will drive the rotation of the planetary gear 3032 below. The planetary gear 3032 will drive the rotation of the sun gear 3033 through meshing, so that the wire harness will generate rotational twisting when passing through the lower wire collecting wheel 3038, the second wire passing wheel 3039 and the upper wire collecting wheel 3037 due to the rotation of the sun gear 3033, so that this section of the wire harness can be bundled due to twisting, and because the wire harness is soaked, the surface of the wire harness is The yarn is not easily shed, which ensures the bundling quality of the wire harness. Finally, the wire harness is transmitted through the second wire outlet 3031 and transmitted through the supporting tangential belt 502 and air-dried by the blowing fan 505 driven by the second motor 504 in the blowing frame 501. The tangential belt of the supporting tangential belt 502 is fitted so that the wire harness can be supported during the air-drying process, thereby ensuring the stability of the air-drying of the wire harness. Finally, the wire harness is wound up by the rotation of the winding roller 703 under the driving force of the sixth motor 705. During this period, when the winding roller 703 needs to be connected due to loading and unloading, the fifth motor 6012 in the pressure block 6010 can be started, and the second threaded The rotation of the rod 6013 drives the displacement rod 6014 to move left and right, and then the displacement rod 6014 drives the displacement of the pressing block 6015 so that the wire bundle passing through during the period can be clamped between the pressing block 6015 and the pressing block 6010, and the pressing block 6015 below can clamp the broken wire at the winding roller 703, and the pressing block 6015 on the upper right side clamps the broken wire at the supporting dragon belt 502 from the front and back opposite direction compared to the previous one, and then the third motor 604 is started, and the fourth motor 607 on one side of the displacement block 606 is driven to move up and down by the rotation of the first threaded rod 605 under the power output of the third motor 604, so that the two pressing blocks 6015 pull the wire bundles in their respective directions up and down and cross-displace, so that The two broken wires can intersect up and down, and finally the intersecting broken wires are processed by the yarn splicing machine 603 under the front and rear extension of the hydraulic telescopic assembly 601, so as to achieve the mechanical yarn splicing effect of the wire harness. During the process, the extension and contraction of the third electric telescopic rod 609 and the eccentric rotation of the third electric telescopic rod 609 driven by the fourth motor 607 on the rotating disk 608 enable the two broken wires to intersect due to the offset rotation and extension. The design of the rubber pad 6016 can make the wire harness clamped more tightly. The converging dragon belt 201 and the supporting dragon belt 502 are prior art, the hydraulic telescopic assembly 601 is prior art and the hydraulic telescopic assembly 601 has the function of front and rear extension, and the oil inlet of the hydraulic telescopic assembly 601 is connected to the oil outlet of the external oil pump.
