Description

Technical Field

[0001] The present application relates to the technical field of textile machinery, and in particular to a yarn unwinding device. Background Art

[0002] In the textile industry, yarn unwinding equipment is an indispensable part. Its function is to unwind the yarn stored on the reel at a constant tension for subsequent weaving or processing. Traditional yarn unwinding equipment usually adopts a mechanical tensioning mechanism. However, the mechanical tensioning mechanism can only adjust the tension manually, but cannot adaptively adjust the tension according to the tension situation, which makes the yarn easily uneven in tension, affecting the quality of the yarn and the quality of subsequent processing. Utility Model Content

[0003] The problem to be solved by the present application is that the existing yarn unwinding equipment is unable to perform adaptive tension adjustment operations according to the tension of the yarn, which results in uneven tension of the yarn and affects the quality of the yarn and the quality of subsequent processing.

[0004] In order to solve the above-mentioned technical problems, the present application provides a yarn unwinding device, including a frame for serving as a basic support, a table for serving as a support is arranged on the upper part of the frame, a yarn roll is arranged on one side of the table, a driving component for driving the yarn roll for unwinding operation is arranged on the upper part of the table, and a tensioning component for adaptively tensioning the yarn is also arranged on the upper part of the table.

[0005] Since the unwinding device of the present application is designed with a driving component and a tensioning component, it is possible to realize the winding and releasing operations of the yarn roll through the driving component, and to realize the adaptive adjustment operation of the yarn tension through the tensioning component, thereby solving the problem that the yarn unwinding device of the prior art cannot adaptively adjust the tension according to the tension condition of the yarn, resulting in uneven tension of the yarn, which affects the quality of the yarn and the quality of subsequent processing.

[0014] The present application relates to a yarn unwinding device, such as Figure 1-6 As shown, the unwinding device includes a frame 4 for serving as a basic support, a table 1 for serving as a support is arranged on the upper part of the frame 4, a yarn roll 5 is arranged on one side of the table 1, and a driving component 6 for driving the yarn roll 5 to perform an unwinding operation is arranged on the upper part of the table 1. In order to be able to maintain a relatively stable tension on the yarn so that the force is evenly applied, a tensioning component 3 for adaptively tensioning the yarn is also arranged on the upper part of the table 1.

[0015] The driving assembly 6 includes a motor 10 and a shaft 9. The motor 10 is arranged on one side of the table 1 and fixedly connected thereto. The shaft 9 connected to the output end of the motor 10 is arranged on the other side of the table 1, and a yarn roll 5 is fixedly sleeved on the upper part of the shaft 9.

[0016] The tensioning assembly 3 includes a reversing member 8 and a traction member 7. The reversing member 8 is arranged on the upper part of the table 1 to guide the yarn from the yarn roll 5. The traction member 7 is arranged on the upper part of the table 1 to tension the yarn from the reversing member 8.

[0017] The reversing member 8 includes a line roller 13, a support rod 12, and a guide roller 11. The line roller 13 is arranged on the upper part of the table 1 for performing preliminary reversing and guiding operations on the yarn. The support rod 12 is arranged on the upper part of the table 1. In order to realize further reversing operations of the yarn, guide rollers 11 that play a reversing supporting role are symmetrically arranged on the upper part of the support rod 12.

[0018] The traction member 7 includes a support plate 16, a winding roller 15, a tension spring 14, and a counterweight 17. The support plate 16 is arranged on the upper part of the table 1 and can rotate around it. A plurality of winding rollers 15 for uniformly tensioning the yarn are evenly arranged at one end of the support plate 16, and a counterweight 17 for balancing is arranged at the other end of the support plate 16. In order to achieve adaptive adjustment of the tension of the yarn, a tension spring 14 connected to the table 1 is also arranged at one end of the upper part of the support plate 16 near the counterweight 17, so that the yarn tension can be adaptively adjusted through the elastic contraction of the tension spring 14 itself and the physical counterweight of the counterweight 17.

[0019] In order to cooperate with the traction member 7 to realize the yarn tensioning and adjusting operation, a roller group 2 for assisting the yarn tensioning operation is arranged on the upper part of the table 1.

[0020] When in use, the yarn reel 5 is fixed on the upper part of the shaft 9, and then the shaft 9 is driven by the motor 10 to realize the yarn reeling and releasing operation. In order to realize the tension adjustment of the yarn, the yarn is made to pass through the line roller 13 and the guide roller 11 in sequence to realize the preliminary reversing operation, and then the yarn is made to pass through the winding roller 15, and then the winding roller 15 is swung around the table 1 with the help of the support plate 16 supporting the winding roller 15, and the counterweight block 17 at the other end of the support plate 16 and the traction of the tension spring 14 are used to make the yarn adaptively and evenly adjust the tension.
