[0001] The utility model relates to the technical field of yarn breakage detection, in particular to a breaking test device for detecting the twist of yarns. Background Technique

[0002] The twist of a yarn refers to the number of turns formed by the helix in the yarn within a certain length. It is one of the important parameters for measuring the tightness and stability of the yarn, and has a direct impact on the quality and performance of the yarn. After the yarn is twisted, a corresponding breaking test device is required to perform a breaking test on the twisted yarn. The breaking test device applies a tensile force to the sample of the tested yarn to perform a breaking test on the twist of the yarn in sequence to ensure the production quality of the yarn.

[0003] Currently, when performing a breaking test on the twist of yarns in the market, generally, a tensile force is directly applied to the yarn manually to perform the breaking test. The operation steps of manual detection by personnel are relatively cumbersome, and there are certain differences in the results detected by personnel. Therefore, we propose a breaking test device for detecting the twist of yarns. Content of the Utility Model

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present invention provides a technical solution: a tensile break test device for detecting the twist of yarn, including a bottom plate 1, a clamping seat 2 and a tension meter 4. A clamping seat 2 is arranged on the surface of the bottom plate 1, and a clamping block 3 penetrates through the inside of the clamping seat 2. A tension meter 4 is arranged above the bottom plate 1, and a hook 5 is connected to one end of the tension meter 4 close to the clamping seat 2. The lower surface of the tension meter 4 is connected to a mounting plate 6, and a fixed seat 7 connected to the bottom plate 1 is arranged below the mounting plate 6. A movable cavity 8 is opened inside the fixed seat 7, and a movable block 9 is inserted into the movable cavity 8. One side edge of the movable block 9 is connected to a rack 10.

[0022] A gear 11 is arranged above the rack 10, and both ends of the gear 11 are connected to the inner wall of the movable cavity 8 through bearing seats. A motor 12 is installed on the outside of the fixed seat 7; the output end of the motor 12 is connected to the gear 11 through a coupling. A through groove 13 is opened at the outer end of the fixed seat 7, and guide grooves 14 are opened on both sides of the fixed seat 7 close to the movable cavity 8; a guide block 15 is butted inside the guide groove 14, and the outer end of the guide block 15 is connected to the outside of the movable block 9. The gear 11 and the rack 10 are in meshing connection, the cross-sectional dimension of the guide block 15 matches the cross-sectional dimension of the guide groove 14, and the guide block 15 and the guide groove 14 are in sliding connection.

[0023] During specific implementation, the two ends of the yarn to be detected are respectively docked between the clamping seat 2 and the hook 5. Subsequently, the motor 12 is started to drive the synchronous rotation of the gear 11 connected to the output end. Since the gear 11 and the rack 10 are meshed, as the gear 11 rotates, the meshed rack 10 below can move outward along the through groove 13. The moving rack 10 drives the movable block 9 and the upper mounting plate 6 to move simultaneously, and under the action of the moving mounting plate 6, the tension meter 4 and the hook 5 are driven to move synchronously, realizing the breaking test of the yarn. Moreover, the movable block 9 stably moves along the inside of the guiding groove 14 through the guiding blocks 15 on both sides until the breaking test of the yarn is completed. Through the mutual cooperation of the gear 11 and the rack 10, the tension meter 4 can be driven to move by itself to conduct the breaking test on the yarn, making the operation of the breaking test device for detecting the twist of the yarn more convenient.

[0024] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in, connecting seats 16 are arranged at both side edges of the bottom plate 1, and connecting plates 17 are inserted into the connecting seats 16; a suction cup 18 is connected below the connecting plate 17, a guiding column 19 penetrates through the connecting plate 17, and both ends of the guiding column 19 are connected to the inner wall of the connecting seat 16; a spring 20 is sleeved outside the guiding column 19, one end of the spring 20 is docked with the connecting plate 17, and the other end of the spring 20 is docked with the inner wall of the connecting seat 16. The guiding columns 19 are equally spaced, and the connecting plate 17 and the connecting seat 16 form a telescopic structure through the spring 20.

[0025] During specific implementation, after the breaking test device is carried and placed in the designated working area, the staff presses the connecting plate 17 downward. While the downward-pressed connecting plate 17 moves downward along the guiding column 19, the connected spring 20 is stretched until the connecting plate 17 is pressed to the limit position, so that the suction cup 18 at the bottom of the connecting plate 17 is tightly sucked to the placement position. On the contrary, when the connecting plate 17 is lifted upward, the suction cup 18 is separated from the placement position. At this time, the unrestricted suction cup 18 can automatically reset upward to the initial position under the elastic force of the spring 20. By arranging the suction cups 18 that can move downward and suck on both sides of the bottom plate 1 to assist in limiting the position of the breaking test device, the breaking test device for detecting the twist of the yarn is placed more stably.

[0026] In summary, when using the breaking test device for detecting the twist of yarn, first move and place the breaking test device in the designated working area, and dock the two ends of the yarn to be detected between the clamping seat 2 and the hook 5 respectively. By starting the cooperation between the motor 12, the gear 11 and the rack 10, the tension gauge 4 and the hook 5 can be moved to realize the breaking test of the yarn. And the movable block 9 moves stably along the inside of the guide groove 14 through the guide blocks 15 on both sides until the breaking test of the yarn is completed. Through the cooperation between the gear 11 and the rack 10, the tension gauge 4 can be driven to move by itself to conduct the breaking test of the yarn. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
