[0001] The utility model relates to the technical field of polyester yarns, in particular to a polyester yarn drawing mechanism. Background Art

[0002] Polyester yarn occupies an important position in the modern textile industry due to its excellent physical and chemical properties. Its wide application and continuous development prospects make it an important variety of synthetic fibers.

[0003] During the actual production of polyester yarn, a wire drawing mechanism with high production efficiency is used to adjust the thickness of the polyester yarn to meet different application scenarios.

[0004] The traditional wire drawing mechanism will put the polyester filament roll on the main shaft, and then drive the main shaft to rotate so that the wire passes through the wire drawing template, thereby achieving the purpose of changing the thickness of the polyester filament. When connecting the polyester filament roll and the main shaft, since the main shaft is in an active state, when limiting the polyester filament roll, the user needs to free his hands to limit the movement of the main shaft, and then use the limit block and the bolts on the main shaft to complete the installation of the polyester filament roll. In such operations, the actions of limiting the movement of the main shaft and tightening the limit block need to be performed simultaneously. Not only are the actual operating steps cumbersome, but the tightness of the connection between the polyester filament roll and the main shaft cannot be guaranteed, which is likely to affect the subsequent wire drawing effect.

[0016] 2.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-5 A polyester yarn drawing mechanism includes: a base 1, a main shaft 2 is rotatably connected to the base 1, an auxiliary pulley group 3, an electric heating tube 4, a drawing template 5 and a driving motor 6 are also provided on the upper surface of the base 1, and the output shaft of the driving motor 6 is fixedly connected to the main shaft 2; a bolt 21 is fixedly installed on the end surface of the main shaft 2, and an auxiliary shaft 22 is fixedly installed on the end surface of the bolt 21 away from the main shaft 2, and a limiting ring 23 is also threadedly connected to the bolt 21; the central axis of the auxiliary shaft 22 coincides with the central axis of the bolt 21, and the circular cross-sectional area of the auxiliary shaft 22 is smaller than the circular cross-sectional area of the bolt 21, so that the limiting ring 23 can pass through the auxiliary shaft 22 and connect with the bolt 21, avoiding interference of the auxiliary shaft 22, thereby ensuring the connection relationship between the limiting ring 23 and the bolt 21 can stably fix the polyester yarn roll on the main shaft 2.

[0025] The two levers 72 are connected with the drive shaft 73 by the two levers 71 to move the lever 72 in a direction of rotation and the two levers 73 are in a forward direction, so that the lever 72 can be rotated to move relative to the lever 73 so that the lever 72 can move relative to the lever 73 in a direction of rotation. When the user limits the position of the polyester filament roll by the limit ring 23, the operating component 8 includes an extension seat 81, a spring box 82, a knob 83, a return spring 84, a movable ring 85, an auxiliary rod 86, a fixed block 87 and a friction ring 88. The extension seat 81 is fixedly mounted on the base 1, the spring box 82 is arranged on the extension seat 81, the knob 83 is fixedly mounted on the transmission shaft 74, the two ends of the return spring 84 are fixedly connected to the knob 83 and the movable ring 85 respectively, the auxiliary rod 86 is fixedly mounted on the side of the movable ring 85, the fixed block 87 is fixedly mounted on the transmission shaft 74, and the friction ring 88 is fixedly mounted on the base 1. The end of the transmission shaft 74 passes through the internal cavity of the movable ring 85 and is fixedly connected to the spring output shaft inside the spring box 82. A hole for passing the auxiliary rod 86 is opened on the fixed block 87, and in the initial state, the auxiliary rod 86 is located on the side of the fixed block 87 away from the friction ring 88.

[0026] The working principle is to set up the polyester yarn roll on the main shaft 2 near the electric heating tube 4, and then pass the polyester yarn through the auxiliary pulley group 3, the electric heating tube 4 and the drawing template 5 in sequence, and finally fix the polyester yarn on another main shaft 2 fixedly connected to the output shaft of the drive motor 6. Start the drive motor 6, and the polyester yarn on the main shaft 2 near the electric heating tube 4 will be heated by the electric heating tube 4 and drawn by the drawing template 5, and then wound on the main shaft 2 connected to the drive motor 6, so as to achieve the purpose of changing the thickness of the polyester yarn through the drawing process.

[0027] When the polyester yarn roll is actually fixed on the main shaft 2, the polyester yarn roll is first put on the main shaft 2, and the transmission shaft 74 is rotated by the knob 83 fixed on the transmission shaft 74. The transmission shaft 74 is fixedly connected to the screw rod 73, and the slide rod 72 fixing the stop block 71 is in a sliding connection relationship with the base 1. The screw rod 73 is symmetrically provided with two sections of spiral threads in opposite directions. The two sections of threads are respectively connected to the two slide rods 72. Therefore, when the screw rod 73 rotates with the transmission shaft 74, the two slide rods 72 drive the stop block 71 to perform a mirror sliding motion in opposite directions. At the same time, the two slide rods 72 and the two stop blocks 71 are The moving blocks 71 are arranged on both sides of the auxiliary shaft 22, and the two stop blocks 71 will synchronously contact and clamp the auxiliary shaft 22 fixed on the bolt 21. The friction patterns on the stop blocks 71 will cooperate with the friction patterns on the surface of the auxiliary shaft 22 to form a certain friction force, thereby limiting the movement of the auxiliary shaft 22, and the bolt 21 is fixed on the main shaft 2, synchronously limiting the movement of the main shaft 2. At this time, the threaded connection relationship between the bolt 21 and the limit ring 23 can be utilized to tighten the limit ring 23, and then the polyester filament roll can be fastened to the main shaft 2, so that the polyester filament roll can rotate as the main shaft 2 rotates.

[0028] When the stop block 71 contacts the auxiliary shaft 22, the movable ring 85 connected to the knob 83 through the return spring 84 is rotated, and the position of the auxiliary rod 86 fixed on the movable ring 85 is offset, and it will pass through the hole reserved on the fixed block 87 and contact the friction ring 88 fixed on the base 1. The fixed block 87 is fixed on the transmission shaft 74, and the end face of the auxiliary rod 86 and the friction ring 88 can also cooperate to generate a certain friction force, thereby limiting the rotation of the transmission shaft 74 and the screw rod 73, thereby temporarily locking the contact state between the stop block 71 and the auxiliary shaft 22, ensuring that when the limit ring 23 is used to limit the polyester yarn roll, the stop block 71 and the auxiliary shaft 22 can stably generate friction to limit the rotation of the main shaft 2; and when it is necessary to release the stop block 71 and the auxiliary shaft 22 When friction is generated between them, the movable ring 85 is pulled back, so that the auxiliary rod 86 returns to the side of the fixed block 87 away from the friction ring 88 through the hole on the fixed block 87. At this time, since the knob 83 has driven the transmission shaft 74 to rotate in advance, and the transmission shaft 74 is also fixedly connected to the output shaft of the spring structure inside the clockwork box 82, the spring inside the clockwork box 82 will be tightened. As the movable ring 85 is pulled, the auxiliary rod 86 does not contact the friction ring 88, the overall structure loses its restriction, and the spring inside the clockwork box 82 is released, which will drive the transmission shaft 74 to rotate in the opposite direction, and then the screw rod 73 rotates in the opposite direction synchronously, so that the two slide rods 72 drive the stop block 71 to slide back to the initial position where it does not contact the auxiliary shaft 22, so that the main shaft 2 can rotate normally and complete the polyester yarn drawing process.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
