Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fiber yarn tubes, and particularly relates to a handheld tension measuring device for fiber yarn tubes. Background Technique
[0002] During the production process of unidirectional ultra-high molecular weight polyethylene fabric, multiple bundles of fibers advance simultaneously into the production equipment, and the winding traction force is the same. In theory, the tensile forces of multiple bundles of fibers are exactly the same. However, in the actual process, the tensions of each roll of fibers are different, and the rotational resistances of the corresponding yarn tubes of the fibers are different. As a result, the resistances after different fibers cancel out the traction force are different, and the forward speed consistency is different. Therefore, the spreading degrees are different when passing through the yarn spreading unit, which affects the performance and appearance of the final fabric. See Figure 2 , the current fiber unwinding form used is passive unwinding, mechanically increasing the rotational resistance of the yarn tube. As the rotation continues, the mechanical resistance method will become loose, thus affecting the fiber tension. Operators cannot discover problems in the first time. See Figure 2 Data shows that the cost of a constant-tension fiber unwinding system is high, and the maintenance cost is high. The efficiency is low during the use of a handheld fiber tension tester, and it is inconvenient to detect when the number of fiber bases is large. Therefore, we propose a handheld tension measuring device for fiber yarn tubes. Content of the Utility Model

[0015] The following further describes the present utility model in conjunction with embodiments.
[0016] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0017] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement to the method of the present utility model under the premise of the concept of the present utility model belongs to the scope of protection required by the present utility model.
[0018] Please refer to Figures 1-3 , the present utility model provides a hand-held tension measurement device for a fiber yarn bobbin, including a servo motor 1. The output shaft of the servo motor 1 is connected with a friction guide wheel 2. A hand-held handle 3 is fixed on the outer wall of the servo motor 1 for moving the whole device. A hanging barb 4 is fixed on the surface of the servo motor 1 for matching the friction guide wheel 2 with a yarn rack. A yarn bobbin 6 is arranged on one side of the friction guide wheel 2. The yarn bobbin 6 cooperates with the friction guide wheel 2 for guiding to form a semi-active fiber 5 active unwinding device, and a fiber 5 is arranged on the yarn bobbin 6.
[0019] The servo motor 1 outputs a stable and uniform rotation speed according to the parameters set for the required tension in production, and the friction guide wheel 2 generates a stable resistance following the rotation of the servo motor 1.
[0020] The servo motor 1 and the friction guide wheel 2 are integrally equipped with a hand-held handle 3 and a hanging barb 4, which facilitates manual inspection of the device and fixation with the yarn rack to form a semi-active fiber 5 active unwinding process.
[0021] The present solution has the following working process: During production, the fiber 5 moves forward, and the friction guide wheel 2 in the device abuts against the yarn bobbin 6. If the tension of the yarn bobbin 6 is greater than the set tension of the servo motor 1, the fiber 5 will move faster, and the taut fiber 5 will become loose. If the tension of the yarn bobbin 6 is less than the set value of the servo motor 1, the fiber 5 will become taut, and the operator will immediately discover and find the corresponding fiber 5 bundle for adjustment. For the specific results, see Figure 3 .
