Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically a flexible cold tray drawing mechanism for high-strength spandex and polyester covered yarns. Background Technology

[0002] High-strength spandex-polyester coated yarn is a new type of textile material composed of high-strength yarn, spandex and polyester. It combines the high strength of high-strength yarn, the high elasticity of spandex and the excellent properties of polyester such as wear resistance and corrosion resistance. It has a wide range of applications in sportswear, medical textiles, industrial filter materials and other fields.

[0003] Publication No. CN203238391U discloses a double cold-plate drawing mechanism for an air-coated yarn machine. The double cold-plate drawing mechanism is set on the frame of the air-coated yarn machine, located between the roller mechanism and the oil tank mechanism. It includes several drawing units arranged horizontally and regularly along the left-right direction of the frame. Each drawing unit consists of two cold-plate mechanisms arranged vertically and vertically. Each cold-plate mechanism includes a cold plate driven by a power mechanism and a driven bearing.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] See Figures 1-4 This utility model provides the following two technical solutions:

[0030] First embodiment: A flexible cold tray drawing mechanism for high-strength spandex and polyester covered yarn, comprising:

[0031] Processing table 1 is used to provide a stable installation foundation and operating platform;

[0032] Take-up assembly 2 is installed on the top of processing table 1. Take-up assembly 2 is used to orderly wind and store the high-strength spandex and polyester covered yarn after the stretching treatment.

[0033] Two guide members 3 are installed on the top of the processing table 1. The guide members 3 are used to limit and guide the transmission path of the covered yarn.

[0034] Tension adjustment component 4 is installed on the processing table 1 and is used to adjust the tension during the stretching process.

[0035] Tensile testing component 5 is installed on processing table 1 and tension adjustment component 4. Tensile testing component 5 is used to detect the actual tension value of the covered yarn during the drawing process in real time.

[0036] The take-up assembly 2 includes two first mounting brackets 21, which are respectively installed on the left and right ends of the top of the processing table 1. A take-up roller 22 and a pay-off roller 23 are rotatably mounted on the two first mounting brackets 21, and a first motor 24 is fixedly mounted on each of the two first mounting brackets 21. The output ends of the two first motors 24 pass through the two first mounting brackets 21 and are fixedly connected to the take-up roller 22 or the pay-off roller 23.

[0037] Both guide members 3 are installed between the two first mounting brackets 21, and the tension adjustment assembly 4 is installed between the two guide members 3.

[0038] Both guide members 3 are composed of a second mounting bracket 31 and a first cold plate 32. The second mounting bracket 31 is fixedly mounted on the top of the processing table 1, and the first cold plate 32 is rotatably mounted on the upper end of the second mounting bracket 31.

[0039] The tension adjustment assembly 4 includes a frame 41, which is fixedly installed on the processing table 1. An electric telescopic rod 42 is fixedly installed on the frame 41. The output end of the electric telescopic rod 42 passes through the frame 41 and is fixedly installed on a mounting plate 43. Two second cold plates 44 are rotatably installed on the bottom of the mounting plate 43.

[0040] The tensile testing assembly 5 includes two third cold plates 51 and two third mounting brackets 52. The two third cold plates 51 are fixedly installed on the bottom of the mounting plate 43, and the two third mounting brackets 52 are installed on the top of the processing table 1. Tensile sensors 53 are fixedly installed on the upper ends of the two third mounting brackets 52, and the polyester covering yarn for testing is installed between the two tensile sensors 53.

[0041] The processing table 1 serves as a stable foundation supporting all components. In the take-up assembly 2, the take-up roller 22 and the pay-off roller 23, driven by the first motor 24, release and wind the covering yarn. Two guide members 3, via the first cold plate 32 on the second mounting frame 31, limit and guide the transmission path of the covering yarn, reducing friction and deviation. The tension adjustment assembly 4, located between the two guide members 3, drives the mounting plate 43 to move up and down with the help of the electric telescopic rod 42, causing the second cold plate 44 at the bottom to change the pressure on the covering yarn to adjust the tension. In the tension testing assembly 5, the third cold plate 51 at the bottom of the mounting plate 43 cooperates with the tension sensor 53 on the third mounting frame 52 on the processing table 1 to detect the tension in real time and transmit the signal to the control system, forming a closed loop of "detection-feedback-adjustment". At the same time, the rotational speeds of the take-up roller 22 and the pay-off roller 23 are controlled in coordination to ensure the stability of the drawing process.

[0042] In this embodiment, the precise tension control of the tension adjustment component 4, combined with the cold-drawing design of the first cold plate 32 and the second cold plate 44, avoids the breakage of the covering yarn due to improper tension or insufficient drawing, reduces the impact of temperature on the yarn performance, and ensures the uniformity of strength, elasticity and elongation of the high-strength spandex and polyester covering yarn. The path stabilization effect of the guide component 3 also reduces entanglement and deviation problems, and improves the product qualification rate. On the other hand, the orderly winding of the take-up component 2 facilitates subsequent processing, the real-time monitoring of the tension testing component 5 reduces the number of downtime adjustments, and the stable installation of each component on the processing table 1 reduces the equipment failure rate. Overall, it improves production efficiency and stability, and is suitable for large-scale processing.

[0043] The second implementation differs from the first implementation in that the two third cold plates 51 and the two second cold plates 44 are located on the same horizontal line, and the two tension sensors 53 and the two first cold plates 32 are located on the same horizontal line.

[0044] The top of the processing table 1 has two slide grooves 6, and two third mounting brackets 52 are slidably installed in the two slide grooves 6 respectively. A bidirectional lead screw 7 is rotatably installed inside the processing table 1. The two third mounting brackets 52 are threaded to both ends of the bidirectional lead screw 7 respectively. A second motor 8 is fixedly installed on the processing table 1. The output end of the second motor 8 passes through the processing table 1 and is fixedly connected to the bidirectional lead screw 7.

[0045] In the take-up assembly 2, the take-up roller 22 and the release roller 23, driven by the first motor 24, complete the release and winding of the covering yarn. The first cold plate 32 of the two guide members 3 guides the covering yarn and is on the same horizontal line as the two tension sensors 53, ensuring that the force direction of the covering yarn is consistent during detection. In the tension adjustment assembly 4, the electric telescopic rod 42 drives the mounting plate 43 to move, and the two second cold plates 44 and the two third cold plates 51 at its bottom are on the same horizontal line, so that the covering yarn is subjected to uniform force to accurately adjust the tension. In the tension testing assembly 5, the third cold plate 51 and the tension sensor 53 cooperate to detect the tension in real time. At the same time, the second motor 8 of the processing table 1 drives the bidirectional lead screw 7 to rotate, allowing the two third mounting brackets 52 to slide in the slide groove 6, thereby adjusting the position of the tension sensor 53 to adapt to different specifications of covering yarn, forming a stable "detection-adjustment" closed loop to ensure the stable operation of the drawing process.

[0046] In this implementation, the setting of the same horizontal line makes tension adjustment and detection more accurate, reducing errors caused by position deviation. Combined with the cold drawing design, it ensures the strength, elasticity and uniformity of the coated yarn, reduces the incidence of breakage, displacement and other problems, and improves the product qualification rate. The third mounting frame 52 achieves sliding adjustment by means of the slide groove 6 and the bidirectional lead screw 7, allowing the mechanism to adapt to different specifications of coated yarn, enhancing its versatility. The orderly winding of the take-up assembly 2, real-time monitoring to reduce the number of downtime adjustments, and stable installation of each component to reduce the failure rate, all contribute to improving production efficiency and stability, and better meeting the needs of diversified and large-scale processing.

[0047] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0048] In use, the polyester covering yarn for testing is installed between two tension sensors 53. The second motor 8 is started to drive the bidirectional lead screw 7 to rotate, causing the two third mounting brackets 52 to slide in the slide groove 6. The tension sensors 53 are adjusted to the appropriate position so that the polyester covering yarn for testing is just taut. Then, the control system is started, and the tension parameters and take-up and undo speeds required for the drawing process are set. The first motor 24 drives the take-up roller 22 and the undo roller 23 to start running at the set speed, driving the covering yarn to be transported along the preset path. During the drawing process, the tension sensor 53 of the tension testing component 5 detects the tension value of the covering yarn in real time and transmits it to the control system. If there is a deviation between the actual tension and the set value, the control system drives the electric telescopic rod 42 to adjust the height of the mounting plate 43, and changes the pressure on the covering yarn through the second cold plate 44 to adjust the tension, forming a closed-loop control. At the same time, the first cold plate 32, the second cold plate 44 and the third cold plate 51 rotate with the covering yarn during the transmission, reducing friction and maintaining a cold drawing environment.
