Description

Technical Field

[0001] The utility model belongs to the technical field of textile, and particularly relates to a dynamic tension regulating component for POY yarn processing. Background Art

[0002] Pre-oriented yarn (POY) refers to an incompletely drawn chemical fiber filament with an orientation degree between that of undrawn yarn and drawn yarn obtained by high-speed spinning; compared with undrawn yarn, it has a certain degree of orientation and good stability, and is often used as a special yarn for drawn textured yarn (DTY). The network yarn of DTY is made by using POY as the raw yarn and performing stretching and false twisting deformation processing, and usually has a certain elasticity and shrinkage. The POY raw yarn can be processed into DTY yarn after passing through a false twisting and texturing machine.

[0003] POY yarn and the processed DTY yarn need to maintain a certain tension during processing on a false twisting and texturing machine; the current method for maintaining the tension of the silk thread on the false twisting and texturing machine is to achieve the maintenance of the silk thread tension through the cooperation of fixed thread-passing pulleys and winding rollers on the machine. However, its tension value is fixed and cannot be dynamically adjusted according to the real-time change of the tension of the silk thread during the processing; this may cause an error in the tension change of the silk thread, resulting in unqualified processing of DTY silk thread or insufficiently tight winding. Summary of the Utility Model

[0004] The utility model provides a dynamic tension regulating component for POY yarn processing. This component can maintain and adjust the tension at both ends of POY yarn and DTY yarn; moreover, this component can monitor the tension of the silk thread in real time during the processing, and adjust the tension of the silk thread in real time according to the monitoring results, so that the silk thread tension is always maintained within a constant range; ensuring the false twisting and texturing effect of POY and the winding tightness of the finished DTY yarn. The utility model solves the problem that during the process of processing POY yarn into DTY yarn, the tension cannot be adjusted in real time dynamically, which may lead to the failure to timely adjust the tension change and affect the processing quality of DTY yarn and the winding tightness of the finished product.

DETAILED DESCRIPTION OF THE EMBODIMENTS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present utility model.

[0062] Embodiment 1

[0063] A dynamic tension adjustment component for POY yarn processing includes: a POY side tension component, a POY side tension adjustment component, a DTY side tension component, a DTY side tension adjustment component, and a tension monitoring component;

[0064] As Figure 1 shown, the POY yarn rack 1 is used to place POY yarn raw materials. On the POY yarn rack 1, a number of POY yarn rollers 2 are regularly distributed. The POY yarn reel is placed on the POY yarn roller 2. The POY yarn material is output from the POY yarn rack 1 and reaches the texturing machine. On the texturing machine, the POY yarn undergoes false twisting, heating, and cooling setting, and finally forms elastic DTY yarn. The finished DTY yarn obtained by processing is wound on the drawn yarn rack 4.

[0065] Each group of POY yarn rollers 2 on the POY yarn rack 1 is correspondingly provided with a group of POY side tension components; and the installation position of the POY side tension components is slightly lower than the position of the POY yarn rollers 2. The POY side tension component in this embodiment is set as the first tension adjustment wheel 3. One end of the shaft rod is connected to the center of the back side of the first tension adjustment wheel 3, and the other end of the shaft rod is rotatably arranged in the rotating shaft seat 301. The rotating shaft seat 301 is arranged on the POY side tension adjustment component. Under the action of the POY side tension adjustment component, the first tension adjustment wheel 3 can move up or down. The POY yarn coming out of the POY yarn roller 2 is first wound around the first tension adjustment wheel 3 and then input into the elastic machine for processing. Through the first tension adjustment wheel 3, the yarn is kept at a certain tension. When the first tension adjustment wheel 3 moves down, the tension of the yarn from the POY yarn rack 1 to the drawn yarn rack 4 can be increased; conversely, when the first tension adjustment wheel 3 moves up, the tension of this section of the yarn decreases.

[0066] The above-mentioned POY side tension adjustment component includes: a gear transmission plate 13, a gear 14, and a motor 10;

[0067] As Figure 1As shown, a back plate 101 is provided on the POY yarn frame 1, and a through hole for installing a gear transmission plate is opened on the back plate 101 of the POY yarn frame 1; sliding grooves are provided on both sides of the through hole; the side of the gear transmission plate 13 is movably embedded in the sliding groove; the gear transmission plate 13 can move in the sliding groove; that is, the gear transmission plate 13 can move up and down relative to the through hole for installation;

[0068] As Figure 5 shown, a tooth structure is provided on the back of the gear transmission plate 13; the front of the gear transmission plate 13 is rotatably provided with a first tension adjusting wheel 3 through a rotating shaft seat 301;

[0069] A gear 14 is provided on the back of the gear transmission plate 13, and the gear 14 meshes with the tooth structure on the back of the gear transmission plate 13; a motor 10 is provided at the axis of the gear 14, that is, the motor rotor is connected to the axis of the gear 14. When the motor 10 rotates forward or backward, it drives the gear 14 to rotate forward or backward, thereby driving the gear transmission plate 13 to move up or down. The gear transmission plate 13 synchronously drives the first tension adjusting wheel 3 to move up or down, and the up and down movement of the first tension adjusting wheel 3 can adjust the tension of the POY silk thread.

[0070] The POY silk reaches the texturing machine and is processed into DTY silk thread. The DTY side tension component on the draw-texturing yarn frame 4 maintains the tension of the DTY silk thread. The DTY side tension component is movably arranged on the DTY side tension adjusting component, and the DTY side tension adjusting component is used to control the DTY side tension component to dynamically adjust in the up and down and horizontal directions to achieve the purpose of adjusting the tension of the DTY silk thread.

[0071] As Figure 1 shown, the above-mentioned DTY side tension component includes: a second tension adjusting wheel 5 and a third tension adjusting wheel 6, and a set of DTY side tension adjusting components are respectively provided corresponding to the lower sides of the second tension adjusting wheel 5 and the third tension adjusting wheel 6.

[0072] As Figure 2 shown, the above-mentioned DTY side tension adjusting component includes: a moving platform 402, a transmission toothed belt 9, a toothed belt driving component, a moving block 11 and an electric control lifting rod 12;

[0073] The moving platform 402 is arranged above the draw-texturing yarn frame 4; two driving component installation grooves are opened in the moving platform 402; a set of toothed belt driving components are arranged in each driving component installation groove;

[0074] A drive belt 9 is provided on each set of toothed belt drive components; the toothed belt drive components are used to control the forward or reverse transmission of the drive belt 9; a moving block 11 is provided above each drive belt 9; the moving block 11 moves along with the drive belt 9; an electric control lifting rod 12 is centrally provided on the upper surface of each moving block 11; the upper ends of the two electric control lifting rods 12 are respectively rotatably provided with a second tension adjusting wheel 5 and a third tension adjusting wheel 6. As Figure 4 shown, the above-mentioned toothed belt drive components include: a gear transmission shaft 901 and a motor 10;

[0075] One gear transmission shaft 901 is provided at each end of the drive component installation groove; both ends of one gear transmission shaft 901 are rotatably provided on the side wall of the drive component installation groove through a shaft rod; one end of the other gear transmission shaft 901 is rotatably provided on the side wall of the drive component installation groove through a shaft rod; the other end is arranged on the rotor of the motor 10;

[0076] The drive belt 9 is provided on the two gear transmission shafts 901, and the contact surface between the drive belt 9 and the gear transmission shaft 901 is engaged by teeth. When the motor 10 rotates forward or backward, it drives the gear transmission shaft 901 to rotate synchronously forward or backward, and the gear transmission shaft 901 drives the drive belt 9 to transmit forward or backward.

[0077] When performing dynamic tension adjustment, the two groups of motors 10 should rotate in opposite directions, and the gear transmission shafts 901 directly controlled by the motors 10 in the two groups also rotate in opposite directions; so that the two drive belts 9 also transmit in opposite directions; the second tension adjusting wheel 5 and the third tension adjusting wheel 6 above the drive belt 9 will move towards or away from each other, so as to realize the tension adjustment of the DTY silk thread; when the second tension adjusting wheel 5 and the third tension adjusting wheel 6 move towards each other and gradually approach, the tension of the DTY silk thread will decrease; on the contrary, when the two move away from each other and gradually move away, the tension of the DTY silk thread will increase. If the tension adjustment of the DTY silk thread cannot be satisfied only by the movement of the second tension adjusting wheel 5 and the third tension adjusting wheel 6 towards or away from each other, the second tension adjusting wheel 5 and the third tension adjusting wheel 6 can be raised or lowered by controlling the electric control lifting rod 12; when the two rise, the tension of the silk thread will increase; on the contrary, when the two drop, the tension of the silk thread will gradually decrease.

[0078] Regardless of whether it is the tension adjustment component on the POY side or the DTY side, the basis for dynamic tension adjustment is based on the result of monitoring the silk thread tension during the processing. If the tension monitoring result shows that the tension deviates from the set range value, the tension adjustment components on both sides will synchronously and dynamically adjust the overall tension of the silk thread.

[0079] As Figure 1As shown in the figure, the above-mentioned tension monitoring component is set as the tension monitor 8; the tension monitor 8 is arranged above the side of the texturing wire frame 4 close to the POY wire frame 1; and the tension monitor 8 is hinged to the support rod through a rotating shaft. A locking screw is arranged on the hinge seat. Tightening the screw can fix the position of the tension monitor 8, and loosening the screw can adjust the position angle of the tension monitor 8; in this way, it is convenient to adjust the position of the tension monitor 8 according to the position of the wire, so that the wire enters the tension monitor 8 straight, and the tension monitor 8 collects the tension value;

[0080] The wire tension value collected by the tension monitor 8 will be fed into the PLC in real time; the control motor 10 of the POY side gear, the motor 10 of the DTY side controlling the transmission belt 9, and the electric control lifting rod 12 controlling the lifting of the second tension adjusting wheel 5 and the third tension adjusting wheel 6 are all communicatively connected to the PLC; according to the collected wire tension value, if dynamic adjustment of the tension is required, the PLC will control the above-mentioned electric control driving components to perform corresponding actions to complete the dynamic adjustment of the tension.

[0081] As a preferred embodiment, usually, after the DTY wire is output from the third tension adjusting wheel 6, it can enter the texturing wire roller 401 for winding; however, in order to avoid the situation that the DTY wire may touch the texturing wire frame 4, as Figure 1 shown, in this embodiment, a support pulley 7 is inclinedly arranged on the side of the texturing wire frame 4 away from the POY wire frame 1 and above the texturing wire frame 4; the support pulley 7 is rotatably arranged on the pulley mounting frame. The DTY wire coming out of the third tension adjusting wheel 6 will pass through the support pulley 7 and then reach the texturing wire roller 401 for winding. In this way, it can avoid the situation that the DTY wire may touch the texturing wire frame 4, and make the DTY wire enter the texturing wire roller 401 smoothly for winding.

[0082] Embodiment 2

[0083] Based on Embodiment 1, in Embodiment 1, the moving block 11 is directly connected above the transmission belt 9, and the moving block 11 is driven by the transmission belt 9 to move. Since the transmission belt 9 itself is a soft material, when the transmission belt 9 drives, the moving block 11 will shake to a certain extent during the movement; resulting in inaccurate wire tension adjustment results during the wire tension adjustment process;

[0084] Therefore, as Figure 2 shown, in this embodiment, on both sides of the driving component installation groove on the moving platform 402, and an inverted "T" - shaped sliding groove 4021 is opened inside the moving platform 402; a sliding block 1101 is movably arranged in the sliding groove 4021; the upper ends of the two sliding blocks 1101 are respectively arranged on both sides of the lower surface of the moving block 11.

[0085] The moving block 11 moves following the driving toothed belt 9, and the sliding block 1101 synchronously moves in the sliding groove 4021 driven by the moving block 11. The sliding block 1101 supports the moving block 11 without affecting the movement of the moving block 11 following the driving toothed belt 9, and avoids the moving block 11 from wobbling during movement.
