Description

Technical Field

[0001] This utility model relates to the field of yarn bobbins, and more particularly to a yarn bobbin shape maintenance structure. Background Technology

[0002] Yarn bobbins are widely used in the textile industry. Yarn is wound into a bobbin to provide raw materials for textiles. However, during use, the yarn on the surface of unused bobbins is prone to loosening and slipping, or even becoming partially entangled or looped, affecting the reuse of the bobbin.

[0003] While existing technologies include yarn bobbin shaping structures, such as the utility model patent "Novel Yarn Bobbin Shape Maintaining Device" applied for by Wuxi Taiping Knitting Co., Ltd. (application number 202120399593.9), the process of placing or removing the yarn bobbin requires unscrewing bolts, loosening nylon threads, and then reinstalling it. This is time-consuming, labor-intensive, and inefficient.

[0004] Therefore, it is necessary to develop new yarn shape maintenance structures for yarn bobbins to facilitate the placement or removal of yarn bobbins, saving time and effort and improving operational efficiency. Utility Model Content

[0005] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, this utility model provides a yarn shape maintenance structure for yarn bobbins. By moving a weight ball up and down on a slide bar, the tension of the elastic thread is automatically adjusted, which facilitates the placement or removal of yarn bobbins, saves time and effort, and has high operating efficiency.

[0006] Technical Solution: This utility model discloses a yarn shape maintenance structure for yarn bobbins, characterized in that: it includes a vertical rod, on which a top plate, a middle plate, and a bottom plate are arranged sequentially from top to bottom; the bottom of the top plate has several connection points; the middle plate has several thread holes corresponding to the connection points, and a boss is provided in the middle of the middle plate; several sliding rods corresponding to the thread holes are provided between the middle plate and the bottom plate, and a weight ball that slides up and down is provided on the sliding rod; the weight ball is connected to an elastic thread, one end of the elastic thread is connected to the weight ball, and the other end of the elastic thread passes through the thread hole and is connected to the connection point.

[0007] In this configuration, a yarn bobbin is placed on the intermediate plate, and the bobbin tube is fitted onto the boss.

[0008] The boss is a frustum-shaped structure that is narrower at the top and wider at the bottom.

[0009] The yarn bobbin is located between several elastic threads, and the elastic threads are attached to the yarn surface of the yarn bobbin.

[0010] The weighted ball has a hole in its center for the sliding rod to pass through.

[0011] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention automatically adjusts the tension of the elastic thread by moving the weight ball up and down on the slide bar, which is convenient for placing or taking out the yarn tube, saving time and effort and increasing the operating efficiency.

Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] The yarn shape maintenance structure of this utility model includes a vertical rod 3, on which a top plate 1, a middle plate 4 and a bottom plate 9 are arranged sequentially from top to bottom; the bottom of the top plate 1 is provided with several connection points 2; the middle plate 4 is provided with several thread holes 6 corresponding to the connection points 2, and a boss 5 is provided in the middle of the middle plate 4; several sliding rods 7 corresponding to the thread holes 6 are provided between the middle plate 4 and the bottom plate 9, and a weight ball 8 that slides up and down is provided on the sliding rod 7; the weight ball 8 is connected to an elastic line 10, one end of the elastic line 10 is connected to the weight ball 8, and the other end of the elastic line 10 passes through the thread hole 6 and is connected to the connection point 2.

[0018] In this invention, a yarn bobbin 11 is placed on the intermediate plate 4, and the bobbin 11 is fitted onto the boss 5. The boss 5 is a frustum structure that is narrow at the top and wide at the bottom. The yarn bobbin 11 is located between several elastic threads 10, and the elastic threads 10 are in contact with the surface of the yarn 12 of the yarn bobbin 11. A hole is provided in the middle of the weight ball 8 for the sliding rod 7 to pass through.

[0019] When in use, without the yarn bobbin 11, the elastic cord 10 hangs taut due to the gravity of the weight ball 8, and the weight ball 8 is close to the bottom plate 9 but does not contact it. When the yarn bobbin 11 is installed, the operator opens the elastic cord 10 and places the yarn bobbin 11 on the protrusion 5 of the middle plate 4. The yarn bobbin 11 is set vertically, and the top of the yarn bobbin 11 does not contact the top plate 1. The elastic cord 10 is attached to the surface of the yarn 12 of the yarn bobbin 11. The weight ball 8 is raised a certain distance but does not contact the middle plate 4. Under the gravity of the weight ball 8, the elastic cord 10 tightens the yarn 12 to prevent the yarn 12 from loosening and slipping.

[0020] This invention allows for the placement and removal of the yarn tube 11 without complicated operations. The tension of the elastic thread 10 is automatically adjusted by the up-and-down movement of the weight ball 8 on the slide bar 7, facilitating the placement or removal of the yarn tube 11. This method is time-saving, labor-saving, and highly efficient.
