Description

Technical Field

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

[0002] Polyester yarn is an important variety of synthetic fiber. It is a fiber-forming polymer made from purified terephthalic acid or dimethyl terephthalate and ethylene glycol through esterification or ester exchange and polycondensation reaction. The characteristic of polyester yarn is that it can withstand chemicals and frequent washing, reducing fading and discoloration of clothes. Therefore, it is often used in hotel uniforms, stone-ground blue denim clothing, sportswear or children's clothing. In the manufacturing process of polyester yarn, a winding device is required to wind it.

[0003] In the prior art, the patent with application number CN202320342577.5 discloses a winding device for the production and processing of chemical fiber polyester yarn. By rotating the rotating rod, the rotating rod drives the turntable to rotate, the turntable drives the worm to rotate, and the worm drives the worm wheel to rotate. Under the action of the rack, the worm wheel drives the mounting plate to move, thereby driving the wire wheel to move to adjust the tension of the chemical fiber polyester yarn. However, the patent CN202320342577.5 cannot detect the tension of the polyester yarn in real time, which makes it difficult to determine the size of the tension of the polyester yarn. If the tension applied is too large, it is easy to cause the polyester yarn to break during the winding process. Therefore, a polyester yarn winding tension adjustment mechanism is proposed.

At the same time, the mounting column 11 moves downward with the connecting frame 5 under the action of its own gravity and the gravity of the tension wheel 28, so that the tension wheel 28 moves the polyester yarn downward, so that the polyester yarn is subjected to a downward force, and because the force is mutual, the polyester yarn gives the tension wheel 28 a The same force in an upward direction causes the tension wheel 28 to transfer the force it receives to the mounting column 11, so that the mounting column 11 applies pressure to the pressure sensor 9, thereby detecting the tension of the polyester yarn in real time. When the pressure sensor 9 and the mounting column 11 are damaged, the pressure sensor 9 is pulled to drive the connecting plate 8 to move, so that the connecting plate 8 drives the mounting block 7 to slide out of the mounting groove 6, thereby replacing or repairing the pressure sensor 9, removing the fixing bolt 27, pulling the mounting column 11 downward, and taking the mounting column 11 out of the limit ring 12 and the connecting groove 10, and then the mounting column 11 can be repaired.

[0026] In summary, the polyester yarn winding tension adjustment mechanism, through the arrangement of the mounting bracket 2, the electric push rod 3, the connecting sleeve 4, the connecting frame 5, the mounting groove 6, the mounting block 7, the connecting plate 8, the pressure sensor 9, the connecting groove 10, the mounting column 11, the limit ring 12 and the tension wheel 28, is convenient for adjusting the tension during the winding of the polyester yarn, and is convenient for detecting the tension of the polyester yarn, thereby avoiding the situation where the tension during the winding of the polyester yarn is too large or too small. Through the arrangement of the mounting groove 6, the mounting block 7 and the connecting plate 8, it is convenient to remove the pressure sensor 9 for replacement or repair, and through the arrangement of the connecting groove 10, the limit ring 12 and the fixing bolt 27, it is convenient to replace the damaged mounting column 11, so as to solve the problems raised in the above-mentioned background technology.
