Description

Technical Field

[0001] This utility model relates to a spandex filament stretching machine that is easy to adjust, and belongs to the field of spandex filament processing technology. Background Technology

[0002] Spandex is a highly elastic synthetic fiber widely used in sportswear, underwear, swimwear and other clothing fabrics that require high elasticity. Spandex has excellent stretchability, can be stretched to more than five times its original length and can quickly return to its original shape, maintaining good elasticity and comfort. This fiber is usually blended with other fibers such as cotton, polyester and nylon to enhance the comfort, breathability and durability of the fabric.

[0003] During the use of spandex filament stretching machines, the tension and guidance of spandex filaments during the stretching process need to be controlled and adjusted by the front auxiliary roller. However, existing stretching machines do not make it convenient to adjust the position of the auxiliary roller, which leads to uneven tension during the stretching process, affecting the stretching effect of spandex filaments, making the fiber elongation rate unstable, and the fiber stretching may be uneven, resulting in some parts being overstretched or understretched, thereby affecting the elasticity, strength and hand feel of the fiber, and ultimately affecting the quality of the final product.

[0004] Therefore, a spandex filament stretching machine that is easy to adjust is proposed. Utility Model Content

An adjustment assembly is provided inside the main frame. The adjustment assembly includes a dual-axis motor, an output shaft, an adjustment plate, a cavity, an electric telescopic rod, a connecting block, an auxiliary roller, and a through hole. The dual-axis motor is fixedly installed at the bottom of the inner side of the main frame. The output shaft is fixedly installed at the output ends on both sides of the dual-axis motor. The adjustment plate is assembled at the end of the two output shafts away from the dual-axis motor. The cavity is opened at the top of the adjustment plate. The electric telescopic rod is fixedly connected to the inner side of the cavity. The connecting block is fixedly connected to the upper end of the electric telescopic rod. The auxiliary roller is movably connected to the inner side of the connecting block via a rotating shaft.

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] Example 1

[0021] like Figure 1-5As shown, this utility model embodiment provides a conveniently adjustable spandex filament stretching machine, including a main frame 1. Fixed seats 2 are fixedly installed on both the left and right sides of the top of the main frame 1. A first stretching roller 4 is movably connected to the inner side of the fixed seats 2. An adjustment assembly 7 is provided inside the main frame 1. The adjustment assembly 7 includes a dual-axis motor 701, an output shaft 702, an adjustment plate 703, a cavity 704, an electric telescopic rod 705, a connecting block 706, an auxiliary roller 707, and a through hole 708. The dual-axis motor 701 is fixedly installed at the bottom of the inner side of the main frame 1, and the output shaft 702 is fixedly installed at the output ends on both sides of the dual-axis motor 701. The adjustment plate 703 is assembled on... Two output shafts 702 are located away from the ends of the dual-axis motor 701. A cavity 704 is opened at the top of the adjusting plate 703. An electric telescopic rod 705 is fixedly connected to the inside of the cavity 704. A connecting block 706 is fixedly connected to the upper end of the electric telescopic rod 705. An auxiliary roller 707 is movably connected to the inside of the connecting block 706 via a rotating shaft. A servo motor 3 is fixedly installed on the left side of the fixed base 2. The output end of the servo motor 3 is fixedly connected to the first stretching roller 4. Connecting frames 5 are fixedly installed on both the left and right sides of the top of the main frame 1. A second stretching roller 6 is movably connected to the inside of the connecting frame 5 via a rotating shaft. The surface of the second stretching roller 6 is in contact with the first stretching roller 4.

[0022] By adjusting the settings of component 7, the position of auxiliary roller 707 can be freely adjusted, allowing the operator to precisely control the tension and guidance of the fiber according to different production needs. This helps to ensure that the spandex yarn maintains uniform stretching during the stretching process, avoiding problems such as uneven stretching or tension fluctuations.

[0023] Example 2

[0024] In one embodiment, a through hole 708 is formed on the top of the two adjusting plates 703. The through hole 708 is connected to the cavity 704. The upper end of the electric telescopic rod 705 extends through the through hole 708 to the outside of the adjusting plate 703 and is connected to the connecting block 706. Support bases 8 are fixedly installed on the left and right sides of the bottom inner side of the main frame 1, and bearings are installed on the inner side of the two support bases 8. The output shaft 702 passes through the bearings on the inner side of the support base 8 and is connected to the adjusting plate 703. The connection between the adjusting plate 703 and the output shaft 702 is assembled by bolts. When needed, it can be quickly disassembled and maintained using conventional tools.

[0025] The through hole 708 serves as a guide, ensuring that the electric telescopic rod 705 drives the connecting block 706 to move along a predetermined trajectory, thus preventing deviation. The support base 8 provides support for the output shaft 702.

[0026] In operation, this invention works by passing spandex yarn through the inner sides of the second stretching roller 6 and the first stretching roller 4 at the top of the auxiliary roller 707. The yarn is squeezed by the mutual contact between the second stretching roller 6 and the first stretching roller 4. At this time, the servo motor 3 can be started to drive the first stretching roller 4 at the output end to rotate, thereby stretching the yarn. When it is necessary to adjust the position of the auxiliary roller 707, the dual-axis motor 701 can be started to drive the output shaft 702 at the output end to rotate. During the rotation of the output shaft 702, the adjusting plate 703 is driven to rotate, so that the upper end of the adjusting plate 703 moves in a circular motion, which drives the electric telescopic rod 705, the connecting block 706 and the auxiliary roller 707 to move in a circular motion. When it moves to the appropriate position, the output end of the electric telescopic rod 705 can be started to drive linear drive, which drives the connecting block 706 to move, thereby adjusting the position of the auxiliary roller 707.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
