Description

Technical Field

[0001] This utility model relates to the technical field of composite yarn processing equipment, and in particular to a multi-stage stretching and shaping device for spring-rebound memory flat functional composite yarn. Background Technology

[0002] Resilient memory flat functional composite yarn is a textile material with special properties. It is usually made by combining a variety of fibers with different properties through a special composite process. Fibers with memory function are combined with fibers with good elasticity to achieve the characteristics of resilience memory. Its flat cross-section design is also to give the material specific properties and appearance effects. This flat structure can increase the specific surface area of ​​the fiber, making the material have better coverage, softness and unique luster.

[0003] In the production process of elastic memory flat functional composite yarn, multi-stage stretching treatment is usually required. Mechanical stretching force causes the molecular chains inside the composite yarn to align in an orderly manner along the stretching direction, thereby significantly improving the fiber's strength, elasticity, abrasion resistance, and other mechanical properties. After stretching treatment, heating and cooling setting are also required. Heat setting further adjusts and stabilizes the molecular chains of the composite yarn at high temperatures, forming a stable crystalline structure, thereby improving its elastic memory performance and dimensional stability. After heat setting, the composite yarn needs to be rapidly cooled to fix the structure formed at high temperatures, which helps maintain the crystalline structure and orientation state of the composite yarn and improves its performance stability.

[0004] Existing multi-stage stretching and shaping devices for spring-loaded memory flat functional composite yarns typically require clamps to hold and fix the ends of the composite yarn to be stretched during actual use, ensuring that the composite yarn remains taut during stretching. However, existing clamps are prone to causing dents on the outside of the composite yarn, increasing the probability of damage. If the composite yarn is partially damaged, the damaged part needs to be cut off, resulting in waste of raw materials and significantly increasing the production cost of the composite yarn. Therefore, this application proposes a multi-stage stretching and shaping device for spring-loaded memory flat functional composite yarns that can reduce production costs. Utility Model Content

[0005] The purpose of this invention is to address the problem that traditional clamps in the background technology easily damage composite yarns, leading to waste of raw materials, and to propose a multi-stage stretching and shaping device for spring-loaded, memory-shaped, flat functional composite yarns that can reduce production costs.

[0034] Example

[0035] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, this utility model proposes a multi-stage stretching and shaping device for a spring-loaded, memory-structured flat functional composite yarn. It includes a support frame 1, with two slide blocks 2 fixedly mounted on the top of the support frame 1. A positioning frame 7 is fixedly mounted on the top of both slide blocks 2. A traction frame 5 is provided on one side of the positioning frame 7, and this traction frame 5 is slidably mounted on the top of the two slide blocks 2. Three winding rollers 9 are rotatably mounted on both the traction frame 5 and the positioning frame 7. The three winding rollers 9 arranged in the same group adopt a three-point layout, allowing the composite yarn to be wound and overlapped on the three winding rollers 9, providing stable tension to the composite yarn and preventing it from slipping during transport. The top of both the traction frame 5 and the positioning frame 7 are fixedly equipped with locking components 6. When multi-stage stretching of the composite yarn is required, the winding roller 9 is locked and fixed by the locking components 6. Then, the part of the composite yarn overlapping the winding roller 9 can be locked and fixed. At this time, the traction frame 5 moves away from the positioning frame 7, and the composite yarn can be stretched. The three-point layout of the winding roller 9, together with the locking components 6, can lock and fix both ends of the part of the composite yarn that needs to be stretched, replacing the traditional clamps. This can prevent damage to the composite yarn, avoid waste of raw materials, and save costs.

[0036] A shaping component 3 is fixedly installed on one side of the slide 2. The shaping component 3 consists of a heating structure and a cold air conveying structure. The heating structure is set on both sides of the flat wire guide cover 31. When the composite wire passes through the flat wire guide cover 31, the heating structure heats and shapes the composite wire inside the flat wire guide cover 31. The cold air conveying structure delivers cold air into the flat wire guide cover 31, thereby rapidly cooling the heat-shaped composite wire, meeting the requirements of heat shaping and rapid cooling of the composite wire. The shaping component 3 is simple to assemble and disassemble, and is easy to maintain, which can reduce the cost of use.

[0037] like Figure 1 and Figure 6As shown, in order to facilitate the heat setting of the stretched composite yarn, heating covers 34 are fixedly installed on the two outer side walls of the flat guide wire cover 31. Heating tubes 35 are fixedly installed inside the heating covers 34. The wires on the heating tubes 35 are plugged into an external power socket to put the heating tubes 35 into the heating state, thereby raising the temperature of the inner section of the heating cover 34. The high-temperature heat is then allowed to pass through the heat conduction holes 36 into the inner section of the flat guide wire cover 31, thereby heating the composite yarn and facilitating its heat setting.

[0038] Furthermore, to facilitate rapid cooling of the heat-set composite yarn, several air inlet branch pipes 32 are fixedly installed on the top of the flat guide wire cover 31. The top ends of the several air inlet branch pipes 32 are all fixedly installed with an air inlet main pipe 33. Cold air is delivered to the air inlet main pipe 33 by an externally installed fan, and then enters the interior of the flat guide wire cover 31 along the air inlet branch pipes 32. This allows for cooling of the heat-set composite yarn. Due to the narrow interior space of the flat guide wire cover 31, the cold air can quickly exchange heat with the hot air inside, ensuring that the composite yarn can be quickly cooled and set.

[0039] Secondly, during the cooling and shaping stage of the composite yarn, cold air can pass through the heat conduction hole 36 into the interior of the heating cover 34, thereby accelerating the cooling speed of the heating tube 35 and preventing a large amount of residual heat inside the heating cover 34 from affecting the cooling and shaping of the composite yarn.

[0040] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in order to facilitate the locking and fixing of the winding roller 9, several limiting rods 61 are fixedly installed on the top of the traction frame 5 and the positioning frame 7. Locking plates 62 are movably installed on the limiting rods 61 in the same group. A circular toothed plate 91 is fixedly installed on the top of the winding roller 9. The locking plate 62 is provided with a locking tooth 621 at one end near the circular toothed plate 91. When the locking plate 62 moves downward, the locking tooth 621 is inserted into the tooth groove on the outer wall of the circular toothed plate 91, thereby locking and fixing the circular toothed plate 91, which effectively improves the convenience of locking and fixing the winding roller 9.

[0041] Furthermore, to facilitate the lifting and lowering movement of the locking plate 62, a support plate 63 is fixedly installed at the top of each of the multiple limit rods 61 in the same group. A cylinder 64 is fixedly installed on the upper surface of the support plate 63. The output end of the cylinder 64 passes through the support plate 63 and is fixedly connected to the locking plate 62. The cylinder 64 can drive the locking plate 62 to lift and lower, which facilitates switching between the rotation and locking states of the winding roller 9.

[0042] like Figures 1-3As shown, in order to improve the stability of the movement of the traction frame 5, a T-shaped groove 21 is cut into the top of the slide block 2, and several T-shaped sliders 51 are fixedly installed at the bottom of the traction frame 5. The T-shaped sliders 51 are embedded in the matching T-shaped grooves 21 and are slidably connected with them. The T-shaped grooves 21 limit the T-shaped sliders 51 in the vertical direction to prevent the traction frame 5 from disengaging from the slide block 2, thereby effectively improving the stability of the traction frame 5 when it moves.

[0043] like Figures 1-3 As shown, to facilitate multi-stage stretching of the composite wire, a variable frequency motor 8 (model: YVF2-315M-10 55kW 380V) is fixedly installed at the bottom of the positioning frame 7. A reciprocating lead screw 4 is fixedly installed at the output end of the variable frequency motor 8, and a connecting plate 52 is fixedly installed at the bottom of the traction frame 5. One end of the reciprocating lead screw 4 passes through the internal threaded hole drilled on the connecting plate 52 and is threadedly connected to it. The variable frequency motor 8 drives the reciprocating lead screw 4 to rotate, which in turn drives the traction frame 5 to move laterally. When the two ends of the composite wire overlapping the traction frame 5 and the positioning frame 7 are locked, the composite wire can be stretched. By using a motor with variable frequency function, the rotation speed of the reciprocating lead screw 4 can be controlled, so that the traction frame 5 can move laterally at different speeds. During the process of the traction frame 5 moving from slow speed to fast speed, the need for multi-stage stretching of the composite wire is met.

[0044] Secondly, in order to improve the stability of the reciprocating lead screw 4 rotation, a lead screw limiting plate 22 is fixedly installed between the two slide blocks 2. The end of the reciprocating lead screw 4 away from the variable frequency motor 8 is inserted into the limiting circular groove cut on the lead screw limiting plate 22 and rotated to connect with it. The lead screw limiting plate 22 limits the end of the reciprocating lead screw 4 away from the variable frequency motor 8, preventing the reciprocating lead screw 4 from shaking during rotation, and effectively improving the stability of the reciprocating lead screw 4 during rotation.

[0045] In this embodiment, the composite yarn is first wound and overlapped on the winding roller 9. When the external winding traction device pulls the composite yarn, the winding roller 9 ensures that the composite yarn remains taut, facilitating its transport. During the multi-stage stretching process of the composite yarn, the cylinder 64 drives the locking plate 62 to move downward. When the locking teeth 621 on the locking plate 62 engage with the tooth grooves on the outer wall of the circular toothed plate 91, the winding roller 9 is locked and fixed. At this time, the winding roller 9 cannot rotate, and the end of the composite yarn near the positioning frame 7 and the traction frame 5 is then locked and fixed. The frequency conversion motor 8 drives the reciprocating screw 4 to rotate. The movement then drives the traction frame 5 to move away from the positioning frame 7, thus stretching the composite wire. During this process, the speed of the reciprocating screw 4 is controlled by the frequency converter motor 8, allowing the traction frame 5 to enter different lateral movement states to meet the requirements of multi-stage stretching of the composite wire. Since both the traction frame 5 and the positioning frame 7 are equipped with three winding rollers 9 arranged in a three-point layout, and the composite wire overlaps on the three winding rollers 9, the composite wire can be locked and fixed when the winding rollers 9 enter the locking state. This replaces the traditional clamps, avoids damage to the surface of the composite wire, prevents waste of raw materials, and reduces production costs.

[0046] After the composite yarn completes multi-stage stretching, it is pulled by an external winding and traction device. When the stretched portion of the composite yarn enters the flat guide cover 31, the heating tube 35 heats the internal area of ​​the heating cover 34. The heat generated enters the flat guide cover 31, which heats the composite yarn. After heat setting, an externally installed fan delivers cold air to the main air inlet 33. When the cold air enters the flat guide cover 31 along the branch air inlet 32, it rapidly cools the heat-set composite yarn, ensuring that the setting component 3 can meet the heat setting and cooling requirements of the composite yarn. Because the setting component 3 has a simple structure and is easy to disassemble and maintain, it can effectively save maintenance costs during long-term use of the device.

[0047] The above specific embodiments are merely several optional embodiments of this utility model.
