Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for texturing machines, and specifically relates to a heating mechanism for a polyester filament texturing machine. Background Technique

[0002] The main function of a texturing machine is to transform untwisted filaments (such as polyester POY, polypropylene, etc.) into elastic filaments with medium and low elastic properties through false twist deformation processing. This textile machinery plays a key role in the field of textile science and technology, especially in the production of elastic filaments with good fluffiness and high stretchability. The process principle of the texturing machine involves heating, stretching, and false twist deformation of the raw filaments to produce the required physical and chemical changes, and finally winding them into bobbins according to specific specifications. This processing process not only changes the physical structure of the filaments but also endows them with different elastic requirements to meet the needs of various textiles.

[0003] During the operation of the texturing machine, it is necessary to pre-heat the polyester filaments to improve their tensile strength. However, due to the relatively fast transmission speed of the polyester filaments in the hot box, the heating effect of the polyester filaments is not good, which affects the processing quality of the polyester filaments and has a certain impact on the production and sale of products. Content of the Utility Model

[0004] The purpose of the utility model is to provide a heating mechanism for a polyester filament texturing machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A heating mechanism for a polyester filament texturing machine, including a heating box. A hot air blower is fixedly installed on the top of the heating box, which can heat the inside of the heating box. A transmission port is opened on the right side of the heating box. A movable roller is rotatably installed inside the heating box. A speed reduction mechanism is arranged on the front of the heating box, which can increase the time for the polyester filaments to move in the heating box. A moving mechanism is arranged inside the heating box, which can make the polyester filaments move left and right for better heating. The speed reduction mechanism includes:

[0006] A rotating shaft. A rotating shaft is rotatably installed on the front of the heating box, which can drive a rotating round rod to rotate. A moving groove is opened at the top of the rotating shaft. A return spring is fixedly installed at the bottom of the moving groove, which can drive the slider to reset. One end of the return spring away from the bottom of the moving groove is fixedly installed with a slider.

[0007] An upper tooth. One end of the slider away from the return spring is fixedly installed with an upper tooth, which can be engaged into the lower tooth to prevent the upper tooth from rotating. A lower tooth is fixedly installed on the front of the heating box. A fixing rod is fixedly installed on the outer wall of the upper tooth.

[0008] Preferably, a limiting rod is fixedly installed on the front surface of the heating box to prevent the upper engaging teeth from rotating excessively, which may cause the polyester filament to wind around the rotating rod. A rotating round rod is fixedly installed on the back surface of the rotating shaft, and a rotating rod is rotatably installed on the back surface of the rotating round rod.

[0009] Preferably, the moving mechanism includes: a sliding groove, which is formed on the outer wall of the rotating shaft to facilitate the movement of the pulley. A lower convex block is fixedly installed at the bottom of the sliding groove, and a ring is rotatably installed at the top of the sliding groove. A tension spring is fixedly installed at the bottom of the ring, which can cause the pulley to reset after being squeezed.

[0010] Preferably, one end of the tension spring away from the ring is fixedly installed with a pulley, which is slidably connected in the sliding groove. A lower cam is fixedly installed at the bottom of the pulley, which can squeeze the lower convex block to move the pulley.

[0011] Preferably, the rotating rods are arranged in a circumferential array centered on the rotating shaft and there are two groups, which can extend the transmission time of the polyester filament in the heating box.

[0012] Preferably, the moving mechanisms are linearly arrayed on the outer wall of the rotating rod, which can better move each polyester filament left and right.

[0013] Compared with the prior art, the present utility model provides a heating mechanism for a polyester filament texturing machine, having the following beneficial effects:

[0014] 1. For this heating mechanism of the polyester filament texturing machine, when the heating effect is not good when the polyester filament passes through the heating box, the upper engaging teeth can be pulled out to cause the slider to drive the return spring to stretch, so that the upper engaging teeth can be disengaged from the lower engaging teeth. By rotating the upper engaging teeth, the rotating round rod can drive the rotating rod to rotate, which can extend the moving time of the polyester filament in the heating box. When the upper engaging teeth are released, the return spring will drive the upper engaging teeth to engage with the lower engaging teeth to prevent rotation, which can extend the moving time of the polyester filament in the heating box and enable better heating.

[0015] 2. For this heating mechanism of the polyester filament texturing machine, when the polyester filament passes through the rotating column, the movement of the polyester filament drives the pulley to rotate in the sliding groove, so that the lower cam squeezes the lower convex block, which can cause the pulley to move in the sliding groove, and then reset through the tension spring. By moving back and forth like this, the polyester filament can be heated more evenly. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] As Figures 1-4 shown, the present utility model provides a technical solution: a heating mechanism for a polyester filament texturing machine, including a heating box 1, a hot air blower 2 is fixedly installed on the top of the heating box 1, which can heat the heating box 1. A conveying port 3 is opened on the right side of the heating box 1, through which polyester filaments can enter. A movable roller 4 is rotatably installed inside the heating box 1, which can play a guiding role for the polyester filaments. A speed reduction mechanism 5 is provided on the front surface of the heating box 1, which can extend the time for the polyester filaments to stay in the heating box 1, so as to achieve a better heating effect. A moving mechanism 6 is provided inside the heating box 1, which can move the polyester filaments left and right to make them heat more evenly. The moving mechanisms 6 are linearly arranged on the outer wall of the rotating rod 510, which can better move each polyester filament left and right.

[0022] Specifically, the deceleration mechanism 5 includes: a rotating shaft 51, a moving groove 52, a return spring 53, a slider 54, an upper engaging tooth 55, a lower engaging tooth 56, a fixed rod 57, a limiting rod 58, a rotating round rod 59, and a rotating rod 510. The front of the heating box 1 is rotatably installed with the rotating shaft 51, which can drive the rotation of the rotating round rod 59. A moving groove 52 is opened at the top of the rotating shaft 51 to facilitate the movement of the slider 54. The bottom of the moving groove 52 is fixedly installed with the return spring 53, which can reset the slider 54. One end of the return spring 53 away from the bottom of the moving groove 52 is fixedly installed with the slider 54 to facilitate the installation of the upper engaging tooth 55. The upper engaging tooth 55 is fixedly installed at the end of the slider 54 away from the return spring 53 and can be engaged into the lower engaging tooth 56 to prevent the upper engaging tooth 55 from rotating. The lower engaging tooth 56 is fixedly installed on the front of the heating box 1 to facilitate the insertion of the upper engaging tooth 55. A fixed rod 57 is fixedly installed on the outer wall of the upper engaging tooth 55 and can touch the limiting rod 58. The limiting rod 58 is fixedly installed on the front of the heating box 1 and can make the upper engaging tooth 55 rotate only one circle when it rotates, preventing excessive rotation from causing the polyester filament to wind around the rotating rod 510. The rotating round rod 59 is fixedly installed on the back of the rotating shaft 51, which can make the rotating shaft 51 rotate and drive the rotation of the rotating round rod 59 at the same time, and is convenient for installing the rotating rod 510. The rotating rod 510 is rotatably installed on the back of the rotating round rod 59, which can make the polyester filament pass through the outer wall of the rotating rod 510 and can extend the time of the polyester filament in the heating box 1. The rotating rods 510 are arranged in a circular array centered on the rotating shaft 51 and there are two groups, which can extend the time of the polyester filament in the heating box 1 during transmission.

[0023] Specifically, the moving mechanism 6 includes: a sliding groove 61, a lower convex block 62, a ring 63, a tension spring 64, a pulley 65, and a lower cam 66. A sliding groove 61 is opened on the outer wall of the rotating shaft 51 to facilitate the movement of the pulley 65. The lower convex block 62 is fixedly installed at the bottom of the sliding groove 61 and can squeeze the lower cam 66. The ring 63 is rotatably installed at the top of the sliding groove 61 to facilitate the installation of the tension spring 64 and make the tension spring 64 rotate. The tension spring 64 is fixedly installed at the bottom of the ring 63 and can reset the pulley 65 after being squeezed. One end of the tension spring 64 away from the ring 63 is fixedly installed with the pulley 65, which can make the pulley 65 rotate while the polyester filament passes through the pulley 65. The pulley 65 is slidably connected in the sliding groove 61. The lower cam 66 is fixedly installed at the bottom of the pulley 65 and can squeeze the lower convex block 62 to make the pulley 65 move towards the ring 63.

[0024] Working principle: When the heating effect is not good when the polyester filament passes through the heating box 1, the upper clamping tooth 55 can be pulled out, so that the slider 54 drives the return spring 53 to stretch. At the same time, the slider 54 slides in the moving groove 52, so that the upper clamping tooth 55 can be disengaged from the lower clamping tooth 56. When the upper clamping tooth 55 is rotated, the rotating shaft 51 can be rotated and the rotating round rod 59 can be driven to rotate. At the same time, the rotating rod 510 can be rotated, so that the moving time of the polyester filament in the heating box 1 can be lengthened. When the upper clamping tooth 55 is released, the return spring 53 will drive the slider 54 to reset so that the upper clamping tooth 55 is clamped in the lower clamping tooth 56 to prevent rotation. If it rotates too much, the fixed rod 57 will be caught by the limiting rod 58, so that the upper clamping tooth 55 can only rotate one circle to prevent the polyester filament from being wound around the rotating rod 510. In this way, the moving time of the polyester filament in the heating box 1 can be lengthened and it can be heated better.

[0025] When the polyester filament passes through the rotating rod 510, the movement of the polyester filament drives the pulley 65 to rotate in the sliding groove 61, so that the lower cam 66 presses the lower convex block 62, which can make the pulley 65 move in the sliding groove 61, drive the ring 63 to rotate, and at the same time drive the tension spring 64 to compress. When the lower convex block 62 leaves the lower cam 66, the tension spring 64 will drive the pulley 65 to reset. By moving back and forth like this, the polyester filament can be heated more evenly in the heating box 1.

[0026] The above generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
