Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of yarn testing, and specifically refers to a yarn abrasion resistance test device. Background Art
[0002] During the processes of winding, spinning, sizing, etc. of glass fibers, it is easy for glass fibers to be abraded and even broken after passing through different tensions and components. Therefore, it is necessary to test the abrasion resistance of yarns before leaving the factory.
[0003] The traditional method for testing the abrasion resistance of yarns is to drive the yarn to reciprocate manually for friction until the yarn breaks, and record the number of times the yarn is frictionally broken. However, there are drawbacks: First, manually driving the yarn to reciprocate cannot ensure that the tension of the yarn remains at a constant value. Moreover, during the reciprocating movement of the yarn, it is necessary to manually count the number of reciprocating movements, which is very easy to count wrong, resulting in inaccurate tests. Therefore, improvements are needed. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a yarn abrasion resistance test device that can solve the problem of inconveniently maintaining a constant force for the yarn in traditional wear resistance tests, and at the same time can solve the problem of inaccurate tests caused by easy errors in manual counting.

An electric telescopic rod is provided at the bottom end inside the outer frame, and a friction wheel is provided at the output end of the electric telescopic rod. A guide rod is provided inside the outer frame, and a slider is slidably provided on the guide rod. A counter is provided at the top of the outer frame.

When the semi-tooth meshes with the rack on the slider, the slider can be made to slide in one direction, realizing the friction of the yarn in one direction. When the semi-tooth meshes with the rack on the support plate, the slider can slide reversely on the guide rod, thereby pulling the yarn back and realizing the reciprocating movement of the yarn.
[0007] Preferably, a sensor is provided on the support plate. The sensor is signal-connected to a counter. When the sensor passes directly below the counter, it can be counted and recognized by the counter.
[0008] Preferably, the friction wheel is arranged in a middle concave shape and is in the same vertical plane as the yarn up and down.
[0009] Preferably, the lower end of the slider is arranged in a groove shape, and the sliding plate slides in the groove, so that when the lead screw rotates, the sliding plate will not rotate.
[0010] Preferably, a control console is provided on the outer frame, and the control console is electrically connected to the electric telescopic rod and the motor.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are some of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present utility model.
[0020] As Figures 1-3 , a yarn abrasion resistance test device of the present utility model includes an outer frame 1. An electric telescopic rod 2 is provided at the bottom end inside the outer frame 1. A control console 20 is provided on the outer frame 1. The control console 20 can control the electric telescopic rod 2 and the motor 17. The output end of the electric telescopic rod 2 is provided with a friction wheel 3. The friction wheel 3 is arranged in a concave shape in the middle and is in the same vertical plane as the yarn 9 up and down. A guide rod 4 is provided inside the outer frame 1. A slider 5 is slidably arranged on the guide rod 4. The lower end of the slider 5 is arranged in a groove shape and a slide plate 11 slides in the groove. In this way, it can be ensured that when the lead screw 10 rotates, the slide plate 11 will not rotate. A counter 6 is provided at the top of the outer frame 1. A sensor 19 is provided on the support plate 15. The sensor 19 is signal-connected to the counter 6. When the sensor 19 passes directly below the counter 6, it can be counted and recognized by the counter 6. A driving device 7 is provided at the upper end of the slider 5. A fastening device 8 is provided at the bottom of the slider 5. The yarn 9 is provided on the fastening device 8;
[0021] As Figures 2-3 , the fastening device 8 includes a lead screw 10. The lead screw 10 is rotatably arranged inside the slider 5. A handwheel 12 is provided at the end of the lead screw 10. A slide plate 11 is threadedly connected to the lead screw 10. A support 13 is provided on the slide plate 11. A connecting ring 14 is provided on the support 13. The yarn 9 can pass through the slide plate 11 and be tied to the connecting ring 14. Driven by the lead screw 10, the slide plate 11 can tension the yarn 9 so that the yarn 9 is kept in a state of a constant force for the abrasion resistance test.
[0022] As Figures 1-2 , the driving device 7 includes a support plate 15. The support plate 15 is arranged on the slider 5. Rack teeth 16 are provided on both the lower end face of the support plate 15 and the upper end face of the slider 5 and are aligned up and down. A motor 17 is provided on the outer frame 1. A half gear 18 is provided at the power output end of the motor 17. The half gear 18 can mesh with the rack teeth 16. When the half gear 18 meshes with the rack teeth 16 on the slider 5, the slider 5 can be made to slide in one direction, realizing the friction of the yarn 9 in one direction. When the half gear 18 meshes with the rack teeth 16 on the support plate 15, the slider 5 can slide reversely on the guide rod 4, so that the yarn 9 can be pulled back, realizing the reciprocating movement of the yarn 9.
[0023] During specific use, first pass the yarn 9 through the slide plate 11 and tie it to the connecting ring 14. Then pass the other end of the yarn 9 through the slide plate 11 and tie it to the connecting ring 14 on the other side. By turning the handwheel 12, the lead screw 10 rotates, and the slide plate 11 will slide in the slider 5, thereby tightening the yarn 9 so that the yarn 9 maintains a constant tension state. Then, by starting the electric telescopic rod 2, the friction wheel 3 rises until the yarn 9 falls into the friction wheel 3 and adheres to the friction wheel 3. By starting the motor 17, the half tooth 18 meshes with the rack 16 on the slider 5, causing the yarn 9 to move in one direction. When the half tooth 18 meshes with the rack 16 on the support plate 15, the slider 5 will drive the yarn 9 to slide in the opposite direction, so that the yarn 9 can reciprocally rub on the friction wheel 3 until it is worn out. When the sensor 19 passes through the lower end of the counter 6, it will be counted once by the counter 6, and finally the total number of times can be recorded to obtain the wear resistance of the yarn 9.
[0024] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the gist of the creation of the present utility model, they design similar structural manners and embodiments to this technical solution without creative efforts, which shall fall within the protection scope of the present utility model.
