Description

Technical Field

[0001] The invention relates to the technical field of textiles, in particular to a raw yarn rack for a polyester fiber texturing machine. Background Art

[0002] Polyester is an important variety of synthetic fiber. The primary polyester fiber needs to undergo a series of post-processing to become a textile fiber with excellent performance. The texturing machine is a textile machine that processes the polyester untwisted yarn into elastic yarn with medium elasticity and low elasticity through false twisting. The raw yarn rack is an important part of the texturing machine. It is used to hang the polyester yarn tube wrapped with polyester raw yarn. During the use of the polyester yarn tube, the polyester yarn tube is directly hung on the screw rod outside the raw yarn rack for rotation. In order to facilitate the placement of the polyester yarn tube, the inner diameter of the polyester yarn tube is much larger than the diameter of the screw rod.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present invention provides a raw yarn rack for a polyester fiber texturing machine, which has the following beneficial effects:

[0017] 1. The raw yarn rack for the polyester fiber texturizing machine can pull the first pull rope synchronously when the pull plate is pulled. The first pull rope generates tension on the connecting plate and drives the connecting plate to rotate inside the short notch with the round rod as the center. The rotation of the connecting plate drives the chassis and the wire drum sleeve plate to rotate. The wire drum sleeve plate rotates and is sleeved on the outside of the screw rod and fits with the side of the polyester wire drum. At the same time, the bearing is provided. After the wire drum sleeve plate is fitted with the polyester wire drum, the polyester wire drum rotates on the outside of the screw rod, and the wire drum sleeve plate is driven by the polyester wire drum to rotate on the outside of the screw rod. The outside of the polyester wire drum is limited by the wire drum sleeve plate, so that the polyester wire drum can be stably rotated on the outside of the screw rod, avoiding the shaking of the polyester wire drum, and improving the stability of the polyester wire drum when rotating.

[0018] 2. The raw yarn rack for the polyester fiber texturizing machine is configured to place a polyester yarn tube directly on the outside of the screw rod, and multiple polyester yarn tubes can be placed directly on the outside of the screw rod at the same time, and then the pull ring is pulled outward from the inside of the placement slot, and the pull ring drives the pull plate to move inside the transverse slot, and the movement of the pull plate pulls the second pull rope, and the second pull rope is pulled and guided by the guide rod to drive the short plate to rotate inside the rotating slot with the rotating shaft as the center, and the rotation of the short plate drives the screw rod and causes the polyester yarn tube to rotate and tilt synchronously, so that the polyester yarn tube is placed in an inclined state after being placed, thereby preventing the polyester yarn tube from detaching from the screw rod.

[0019] 3. The raw yarn rack for the polyester fiber texturizing machine is configured such that when a wire tube sleeve is sleeved on the outside of the screw rod, the elastic force generated by the first spring drives the round table and the support column to apply elasticity to the connecting ring and the wire tube sleeve. The wire tube sleeve is tightly fitted to the outside of the polyester wire tube by the elastic force generated by the first spring. The elastic force applied by the first spring increases the friction component between the wire tube sleeve and the polyester wire tube, so that the wire tube sleeve can stably drive the polyester wire tube to rotate synchronously.

[0020] 4. The raw yarn rack for the polyester fiber texturizing machine drives the movable plate to move inside the movable slot when the pull plate is pulled, and the movement of the movable plate drives the second spring to contract inside the movable slot, and when the pull plate needs to be reset, the elastic force generated by the second spring drives the movable plate to move inside the movable slot and simultaneously drives the pull plate to move back into the transverse slot, thereby achieving the effect of facilitating the device to quickly disassemble or install the polyester yarn tube.

[0021] 5. The raw yarn rack for the polyester fiber texturizing machine is configured such that after the pull ring is pulled out to the outside of the placement slot, the pull ring drives the card shells on both sides to move outward synchronously and detach from the inside of the placement slot. After the card shell detaches from the inside of the placement slot, the elasticity generated by the second torsion spring drives the card shell to rotate outside the fixed pile. After the card shell rotates and opens, the pull ring is released and the elastic force generated by the second spring pulls the pull plate into the inside of the transverse slot. At this time, the pull plate drives the card shell to make the card roller engage with the inside of the card slot and fix the position of the pull plate. At the same time, the rotation angle of the short plate and the screw rod in the rotating slot is fixed, so as to achieve the effect of quickly placing the polyester yarn tube and rotating it in parallel.

[0042] The regulating component also includes two movable slots 42, which are respectively opened on both sides of the inner wall of the transverse slot 15. A movable plate 43 is movably connected inside each movable slot 42. The opposite sides of the two movable plates 43 are respectively fixedly connected to the two sides of the outside of the pull plate 40. The pull plate 40 slides laterally inside the transverse slot 15 through the two movable plates 43.

The outside of the limiting rod 45 is movably sleeved with a second spring 44, and the two ends of the second spring 44 are respectively fixedly connected to the side of the movable plate 43 facing the inner wall of the movable slot 42.

[0043] Both sides of the outside of the pull plate 40 are provided with clamping components for fixing, and each clamping component includes a fixed pile 50 and a clamping roller 52, the clamping roller 52 is fixedly connected to the outside of the side beam 14, the fixed pile 50 is fixedly connected to the outside of the pull plate 40, and a rotating roller 55 is fixedly connected inside the fixed pile 50, and a card shell 54 is arranged outside the rotating roller 55, and an empty groove 51 is opened at one end of the card shell 54 close to the fixed pile 50, and two ends of the rotating roller 55 are respectively rotatably connected to the two sides of the inner wall of the empty groove 51, and the card shell 54 rotates on the outside of the fixed pile 50 through the empty groove 51 and the rotating roller 55, and a clamping groove 53 adapted to the diameter of the clamping roller 52 is opened on the side of the card shell 54 close to the side beam 14, and circular grooves 56 are opened on both sides of the outside of the fixed pile 50, and a second torsion spring 57 is fixedly connected to the side of each circular groove 56 facing the inner wall of the empty groove 51, and the second torsion spring 57 is movably sleeved on the outside of the rotating roller 55.

[0044] When in use, the first step is to place the polyester yarn tube directly on the outside of the screw rod 22, and multiple polyester yarn tubes can be placed directly on the outside of the screw rod 22 at the same time, and then pull the pull ring 41 outward inside the placement slot 46, and the pull ring 41 drives the pull plate 40 to move inside the transverse groove 15. The movement of the pull plate 40 pulls the second pull rope 28. The second pull rope 28 is pulled and guided by the guide rod 29 to drive the short plate 21 to rotate inside the rotating slot 20 with the rotating shaft 23 as the center. The rotation of the short plate 21 drives the screw rod 22 and causes the polyester yarn tube to rotate and tilt synchronously, so that the polyester yarn tube is placed in an inclined state after placement, thereby preventing the polyester yarn tube from detaching from the screw rod 22.

[0045] In the second step, when the pull plate 40 is pulled, the first pull rope 25 will be pulled synchronously. The first pull rope 25 is pulled to generate tension on the connecting plate 30 and drive the connecting plate 30 to rotate inside the short notch 27 with the round rod 33 as the center. The rotation of the connecting plate 30 drives the chassis 35 and the wire tube sleeve 36 to rotate. The wire tube sleeve 36 rotates and sleeves on the outside of the screw rod 22 and fits with the side of the polyester wire tube. At the same time, the bearing 32 is provided. After the wire tube sleeve 36 is fitted with the polyester wire tube, the polyester wire tube rotates on the outside of the screw rod 22, and the wire tube sleeve 36 is driven by the polyester wire tube to rotate on the outside of the screw rod 22. The outside of the polyester wire tube is limited by the wire tube sleeve 36, so that the polyester wire tube can be stably rotated on the outside of the screw rod 22, avoiding the shaking of the polyester wire tube, and improving the stability of the polyester wire tube when rotating.

[0046] In the third step, when the wire tube sleeve plate 36 is sleeved on the outside of the screw rod 22, the elastic force generated by the first spring 37 drives the round table 38 and the support column 39 to apply elasticity to the connecting ring 310 and the wire tube sleeve plate 36. The wire tube sleeve plate 36 is tightly fitted with the outside of the polyester wire tube by the elastic force generated by the first spring 37. The elastic force applied by the first spring 37 increases the friction component between the wire tube sleeve plate 36 and the polyester wire tube, so that the wire tube sleeve plate 36 can stably drive the polyester wire tube to rotate synchronously.

[0047] In the fourth step, when the pull plate 40 is pulled, the pull plate 40 drives the movable plate 43 to move inside the movable slot 42, and the movement of the movable plate 43 drives the second spring 44 to contract inside the movable slot 42, and when the pull plate 40 needs to be reset, the elastic force generated by the second spring 44 drives the movable plate 43 to move inside the movable slot 42 and simultaneously drives the pull plate 40 to move back into the inside of the transverse slot 15, thereby achieving the effect of facilitating the device to quickly disassemble or install the polyester yarn tube.

[0048] The fifth step is to pull the pull ring 41 out of the placement slot 46, and the pull ring 41 drives the card shells 54 on both sides to move outward synchronously and detach from the inside of the placement slot 46. After the card shells 54 detach from the inside of the placement slot 46, the elasticity generated by the second torsion spring 57 drives the card shells 54 to rotate outside the fixed pile 50, and after the card shells 54 rotate and open, the pull ring 41 is released and the elastic force generated by the second spring 44 pulls the pull plate 40 into the inside of the transverse groove 15. At this time, the pull plate 40 drives the card shell 54 to make the card roller 52 engage in the inside of the card slot 53 and fix the position of the pull plate 40. At the same time, the rotation angle of the short plate 21 and the screw rod 22 in the rotating slot 20 is fixed, so as to achieve the effect of quickly placing the polyester yarn tube and rotating it in parallel.
