Description

Technical Field

[0001] This utility model relates to the field of drawing mechanism technology, specifically a drawing mechanism for spandex and polyester covered yarn with tension protection. Background Technology

[0002] To improve the elasticity of polyester, spandex yarn is usually mixed into the polyester yarn. This requires a drawing mechanism to stretch the spandex-polyester bundled yarn.

[0003] According to a public disclosure of an automated polyester staple fiber drawing mechanism (publication number: CN215800120U), in the above application, the operation of the drive motor causes its output end to drive the rotating rod a to rotate, which in turn causes the drawing roller to rotate. The rotation of the drawing roller will draw the polyester staple fiber. During the drawing process, the leveling roller b and the leveling roller a will be pulled and rotated, and the polyester staple fiber will be leveled between the leveling roller b and the leveling roller a.

[0004] This device uses drawing rollers to draw polyester staple fibers, but it lacks a guiding mechanism. During the drawing process, the polyester staple fibers easily accumulate on the drawing rollers, leading to entanglement, knotting, and even breakage, thus affecting subsequent processing.

[0023] like Figure 1-4As shown, this utility model provides a technical solution: a spandex-polyester covered yarn drawing mechanism with stretch protection, including an operating table 1, a bracket 2 fixedly installed on the top of the operating table 1, a motor 3 fixedly installed on the outer wall of the bracket 2, a drawing roller 4 fixedly installed at the output end of the motor 3, the end of the drawing roller 4 away from the motor 3 passing through the bracket 2 and rotatably connected to the inner wall of the bracket 2, the drawing roller 4 and the bracket 2 are rotatably connected at the passage, the motor 3 is started to drive the drawing roller 4 to rotate, the rotation of the drawing roller 4 is used to draw the spandex-polyester covered yarn, a gantry frame 5 is fixedly installed on the top of the operating table 1, a lower leveling roller 6 is rotatably connected to the inner wall of the gantry frame 5, a cylinder 7 is fixedly installed on the inner wall of the gantry frame 5, the piston end of the cylinder 7 is fixed A slider 8 is installed, and an upper leveling roller 9 is rotatably connected to the side wall of the slider 8. The spandex polyester covering yarn passes between the upper leveling roller 9 and the lower leveling roller 6, then through the guide hole 109 and is wound around the drawing roller 4. A guide mechanism 10 is provided on the operating table 1. By setting the guide mechanism 10, the drawing roller 4 can evenly draw the spandex polyester covering yarn, avoiding the accumulation and entanglement of the spandex polyester covering yarn, thereby avoiding the knotting or even breakage of the spandex polyester covering yarn. A cleaning mechanism 11 is provided on the guide mechanism 10. By setting the cleaning mechanism 11, the surface of the spandex polyester covering yarn can be cleaned to prevent the fiber filaments attached to the surface of the spandex polyester covering yarn from affecting the drawing effect of the spandex polyester covering yarn.

[0024] The aforementioned guiding mechanism 10 includes a rotating shaft 101, a sliding rod 102, a connecting rod 103, a turntable 104, a limiting rod 105, a transmission belt 106, a limiting groove 107, a guide block 108, a guide hole 109, and a connecting rod 1010. One end of the rotating shaft 101 is rotatably connected to the inner wall of the operating table 1, and the other end of the rotating shaft 101 passes through the operating table 1 and is fixedly installed with the turntable 104. The rotating shaft 101 is rotatably connected to the operating table 1 at the point where it passes through. The limiting rod 105 is fixedly installed on the outer wall of the turntable 104. The drawing roller 101 and the drafting roller 4 are connected by a transmission belt 106. When the drafting roller 4 rotates, the transmission belt 106 drives the rotating shaft 101 to rotate synchronously. When the rotating shaft 101 rotates, it drives the turntable 104 to rotate synchronously. The slide rod 102 is slidably connected to the bottom of the operating table 1. A limit groove 107 is opened on the slide rod 102. The outer wall of the limit rod 105 is attached to the inner wall of the limit groove 107. When the turntable 104 rotates, it drives the limit rod 105 to make a circular motion around the rotating shaft 101. Simultaneously, the limiting rod 105 moves up and down against the inner wall of the limiting groove 107 and pushes and pulls the slide rod 102 back and forth, causing the slide rod 102 to slide back and forth at the bottom of the operating table 1. A guide block 108 is slidably connected to the inner wall of the operating table 1, and a guide hole 109 is provided on the guide block 108. As the guide block 108 slides back and forth, it can drive the spandex polyester covering yarn to move back and forth synchronously with the guide hole 109, so that the drawing roller 4 can draw the spandex polyester covering yarn evenly and avoid the accumulation of spandex polyester covering yarn. The winding process avoids knotting or even breakage of the spandex and polyester covering yarn. A connecting rod 1010 is fixedly installed at the bottom of the guide block 108. One end of the connecting rod 103 is hinged to the bottom of the slide rod 102, and the other end of the connecting rod 103 is hinged to the outer wall of the connecting rod 1010. When the slide rod 102 slides back and forth, it pushes and pulls the connecting rod 103 back and forth, causing the connecting rod 103 to push and pull the connecting rod 1010 back and forth, so that the connecting rod 1010 drives the guide block 108 to slide back and forth on the inner wall of the operating table 1.

[0025] The aforementioned cleaning mechanism 11 includes a sliding frame 111, a brush 112, a pull wheel 113, a U-shaped rod 114, and a push rod 115. The sliding frame 111 is slidably connected to the side wall of the guide block 108. The brush 112 is fixedly installed on the inner wall of the sliding frame 111. As the sliding frame 111 reciprocates, it works in conjunction with the brush 112 to clean the surface of the spandex-polyester covered yarn, preventing the fibers adhering to the surface of the spandex-polyester covered yarn from affecting its pulling effect. The U-shaped rod 114 is fixedly installed on the side wall of the sliding frame 111. The pull wheel 113 is rotatably connected to the outer wall of the guide block 108. The outer wall is attached to the outer wall of the bracket 2. While the guide block 108 slides back and forth on the inner wall of the operating table 1, it will drive the pulley 113 to roll back and forth against the side wall of the bracket 2. At this time, the pulley 113 will rotate back and forth against the side wall of the guide block 108. A push rod 115 is fixedly installed on the top of the pulley 113. The outer wall of the push rod 115 is attached to the inner wall of the U-shaped rod 114. While the pulley 113 rotates back and forth, it will drive the push rod 115 to move back and forth against the inner wall of the U-shaped rod 114 and push and pull the U-shaped rod 114 back and forth, so that the U-shaped rod 114 drives the slide frame 111 to slide back and forth against the side wall of the guide block 108.

[0026] Working principle: The spandex-polyester covering yarn is passed between the upper leveling roller 9 and the lower leveling roller 6, then through the guide hole 109 and wound around the drawing roller 4. The motor 3 is started to drive the drawing roller 4 to rotate. The rotation of the drawing roller 4 draws the spandex-polyester covering yarn. At the same time, the rotation of the drawing roller 4, in conjunction with the transmission belt 106, drives the rotating shaft 101 to rotate synchronously. The rotation of the rotating shaft 101 drives the turntable 104 to rotate synchronously. The rotation of the turntable 104 drives the limiting rod 105 to make a circular motion around the rotating shaft 101. At the same time, the limiting rod 105 moves up and down and pushes and pulls the sliding rod back and forth against the inner wall of the limiting groove 107. 102, causing the slide bar 102 to slide back and forth at the bottom of the operating table 1. While the slide bar 102 slides back and forth, it pushes and pulls the connecting rod 103 back and forth, causing the connecting rod 103 to push and pull the connecting rod 1010 back and forth. The connecting rod 1010 drives the guide block 108 to slide back and forth on the inner wall of the operating table 1. While the guide block 108 slides back and forth, it works with the guide hole 109 to drive the spandex polyester covering yarn to move back and forth synchronously, so that the drawing roller 4 can draw the spandex polyester covering yarn evenly, avoiding the spread and entanglement of the spandex polyester covering yarn, thereby avoiding the knotting or even breakage of the spandex polyester covering yarn, and fully protecting the spandex polyester covering yarn.

[0027] As the guide block 108 slides back and forth on the inner wall of the operating table 1, it drives the pulley 113 to roll back and forth against the side wall of the bracket 2. At this time, the pulley 113 will rotate back and forth on the side wall of the guide block 108. While the pulley 113 rotates back and forth, it drives the push rod 115 to move back and forth against the inner wall of the U-shaped rod 114 and push and pull the U-shaped rod 114 back and forth. This causes the U-shaped rod 114 to drive the slide frame 111 to slide back and forth on the side wall of the guide block 108. While the slide frame 111 slides back and forth, it can work with the brush 112 to clean the surface of the spandex polyester covering yarn, so as to prevent the fibers attached to the surface of the spandex polyester covering yarn from affecting the tensioning effect of the spandex polyester covering yarn.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
