Description

Technical Field

[0001] This utility model relates to the fields of textile testing technology and textile instrumentation, and in particular to a textile fiber strength testing device. Background Technology

[0002] Tensile strength of textile fibers is a key physical indicator for evaluating textile quality, directly affecting the spinnability of yarns and the durability of the final fabric. Therefore, accurate strength testing of textile fibers is crucial in raw material quality control, production process optimization, and new product development within the textile industry.

[0003] Currently, textile fiber strength testing devices for this purpose are widely used. These devices typically apply controlled tension to a fixed fiber sample through a precise tensile mechanism until the sample breaks, thereby determining its strength and elongation. Throughout the testing process, the clamping mechanism is responsible for firmly fixing both ends of the fiber sample and is a key component for effectively transmitting tensile force to the sample; the reliability of its clamping directly determines the accuracy of the test results.

[0004] However, in actual testing, the textile fiber samples to be tested are diverse in form, mainly divided into two categories: one is strip-shaped fibers with a certain width, such as fiber bundles, rovings, or fabric strips; the other is linear fibers with a very small diameter, i.e., various types of yarns. These two types of fibers have drastically different requirements for clamping methods. Strip-shaped fibers require uniform planar pressure to prevent slippage, while linear fibers are prone to premature breakage due to stress concentration at the clamping point, requiring methods such as winding to disperse the clamping force. Existing testing devices typically design their clamping mechanisms only for one type of fiber, resulting in a fixed structure that makes it difficult for a single device to be compatible with the testing of both types of fibers, leading to poor versatility. When different types of fibers need to be tested, users have to replace the entire set of clamps or even the entire device, which is not only cumbersome and inefficient but also increases the testing costs for enterprises. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a textile fiber strength testing device, which aims to improve the problems of the existing textile fiber strength testing devices, such as the single structure and fixed function of the clamping mechanism, which cannot be compatible with the testing of different fiber shapes such as strips and lines, resulting in poor equipment versatility and low testing efficiency. This utility model aims to provide a textile fiber strength testing device with an improved structure that can effectively solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a textile fiber strength testing device, comprising: a stretching mechanism and a clamping mechanism; the stretching mechanism is provided with a slider capable of linear motion, and the clamping mechanism is connected to the slider.

[0007] The clamping mechanism has a first clamping component and a second clamping component that can be selectively assembled with the slider.

[0008] The first clamping assembly includes a C-block, a connecting rod, a clamping plate, and a second screw; one end of the connecting rod is fixedly connected to the slider, and the other end is connected to the C-block; two opposing clamping plates are provided inside the C-block, and the second screw passes through the C-block and abuts against one of the clamping plates.

[0009] The second clamping assembly includes a mounting plate, a first winding rod, a second winding rod, and a third screw; the mounting plate is detachably fixedly connected to the slider; the mounting plate is provided with the first winding rod and the second winding rod that are parallel to each other, and the third screw is threaded through the mounting plate and drivenly connected to the first winding rod or the second winding rod.

[0010] Preferably, the stretching mechanism further includes a motor, a first screw, and a guide tube; the slider is threadedly connected to the first screw, and the slider is slidably sleeved on the guide tube; the motor drives the first screw to rotate through a transmission connection.

[0011] Preferably, the tensioning mechanism further includes gears and a transmission belt; the output end of the motor is fixedly connected to the gears on both the first screw and the motor, and the two gears are connected by the transmission belt.

[0012] Preferably, one of the clamping plates in the first clamping assembly is fixed to the inner wall of the C-shaped block, and the other clamping plate is movably configured, with the end of the second screw abutting against the movably configured clamping plate.

[0013] Preferably, the axis of the third screw in the second clamping assembly is perpendicular to the axes of the first winding rod and the second winding rod.

[0014] Preferably, the textile fiber strength testing device further includes a first housing and a second housing; the stretching mechanism and the clamping mechanism are both installed inside the second housing.

[0015] Preferably, the device further includes a control panel and control buttons; both the control panel and the control buttons are disposed on the outer surface of the first housing.

[0016] Preferably, both ends of the guide tube are fixed to the inner wall of the second housing, and the first screw is arranged parallel to one side of the guide tube.

[0017] This utility model has the following beneficial effects: In this invention, by setting up a modular clamping mechanism with a first clamping component and a second clamping component that can be selectively assembled, the problems of simple clamping mechanism structure, poor compatibility with different fiber shapes such as strips and lines, and narrow application range of the existing detection device are solved. This achieves the technical effect of greatly enhancing the versatility and applicability of the device, and one device can meet the detection needs of different fiber shapes, thereby improving the detection efficiency.

[0018] This invention solves the problem in existing technologies where uneven clamping force can easily lead to sample slippage or excessive local stress when clamping strip fibers. By employing a clamping method that combines a C-shaped block, a clamping plate, and a second screw, this invention achieves the technical effect of applying a uniform and stable planar clamping force to the strip fibers, effectively preventing slippage and damage to the samples during the stretching process, and ensuring the accuracy of the test data.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4This utility model provides a textile fiber strength testing device, which aims to solve the problem that the existing clamping mechanism has a single structure and cannot be compatible with textile fibers of different shapes such as strips and lines, resulting in unreliable clamping and low testing accuracy.

[0023] like Figure 1 As shown, a textile fiber strength testing device includes a first housing 2 and a second housing 4, which together constitute the support frame and outer shell of the device. A control panel 1 for setting parameters and a control button 3 for starting and stopping the device are provided on the outer surface of the first housing 2. A tensioning mechanism 5 and a clamping mechanism 6 are installed inside the second housing 4. The tensioning mechanism 5 includes a slider 501 capable of linear motion, and the clamping mechanism 6 is connected to the slider 501 of the tensioning mechanism 5. The core innovation of the clamping mechanism 6 is that it includes a first clamping component and a second clamping component that can be selectively assembled with the slider 501, thereby allowing for the replacement of the appropriate clamping component according to the morphology of the fiber to be tested. When it is necessary to inspect strip-shaped textile fibers, the first clamping assembly should be selected, such as... Figure 3 As shown, the first clamping assembly includes a C-shaped block 602, which is fixedly connected to the slider 501 via a connecting rod 601. The C-shaped block 602 has two opposing clamping plates 604 inside, and also has a second screw 603. The second screw 603 is threaded through one side of the C-shaped block 602, and the end of the second screw 603 abuts against one of the clamping plates 604. By rotating the second screw 603, the clamping plate 604 can be driven to move, thereby clamping or releasing the strip fiber. When it is necessary to detect linear textile fibers, the second clamping assembly is used, such as... Figure 4 As shown, the second clamping assembly includes a mounting plate 605, which is detachably fixed to the slider 501. The mounting plate 605 is provided with a first winding rod 607 and a second winding rod 608 that are parallel to each other for winding linear fibers. The mounting plate 605 is also provided with a third screw 606, which is threaded through the mounting plate 605 and forms a driving connection with the first winding rod 607 or the second winding rod 608. By rotating the third screw 606, the first winding rod 607 or the second winding rod 608 can be changed.

[0024] The tensioning mechanism 5, which realizes the linear motion of the slider 501, is described in detail below: The tensioning mechanism 5 specifically includes a motor 506, a first screw 503, a guide tube 502, a gear 504, and a transmission belt 505; the motor 506 is fixedly installed inside the second housing 4 as a power source; the first screw 503 and the guide tube 502 are both located inside the second housing 4, and the first screw 503 is arranged parallel to one side of the guide tube 502; both ends of the guide tube 502 are fixed to the inner wall of the second housing 4 to provide guidance and limit for the movement of the slider 501; the output end of the motor 506 and one end of the first screw 503 are both fixedly connected to the gear 504, and the two gears 504 are connected by the transmission belt 505, thereby transmitting the power of the motor 506 to the first screw 503, driving the first screw 503 to rotate; The slider 501 is threadedly connected to the first screw 503, and the slider 501 is slidably sleeved on the guide tube 502. This structural cooperation means that when the first screw 503 rotates under the drive of the motor 506, the slider 501 cannot rotate with it due to the constraint of the guide tube 502, and can only perform precise linear reciprocating motion along the axis of the guide tube 502, thereby stably converting the rotational motion of the first screw 503 into the linear stretching motion of the slider 501.

[0025] In a preferred embodiment, to achieve stable and uniform clamping of the strip fiber, one clamping plate 604 of the first clamping assembly is fixed to the inner wall of the C-block 602, while the other clamping plate 604 is movably set. The end of the second screw 603 abuts against the center of the back of the movably set clamping plate 604, thereby ensuring the uniform transmission of driving force. As another preferred embodiment, in order to achieve efficient tightening and locking of the linear fibers, the axis of the third screw 606 in the second clamping assembly is perpendicular to the axes of the first winding rod 607 and the second winding rod 608. This orthogonal arrangement allows one of the winding rods to be directly driven to translate in a direction perpendicular to the screw axis by rotating the third screw 606, thereby precisely adjusting and tightening the gap between the two winding rods.

[0026] Working principle: When the device is started via the control panel 1 and control button 3, the motor 506 starts to rotate. The rotation of the motor 506 is transmitted to the first screw 503 through the gear 504 and the transmission belt 505, driving the first screw 503 to rotate precisely. Since the slider 501 is threadedly connected to the first screw 503 and the slider 501 is slidably sleeved on the guide tube 502, the slider 501 cannot rotate under the limiting action of the guide tube 502. Therefore, the slider 501 converts the rotational motion of the first screw 503 into a stable linear motion along the axial direction of the guide tube 502. When performing strip fiber testing, the operator first rotates the second screw 603 of the first clamping assembly to firmly fix the strip fiber sample in the C-block 602 with the clamping plate 604. When the slider 501 starts to move linearly, the connecting rod 601 of the first clamping assembly moves synchronously with the slider 501, thereby driving the C-block 602 and the strip fiber sample fixed by the clamping plate 604 to move together, thus applying a tensile force to the strip fiber sample. When performing linear fiber testing, the operator first winds the linear fiber sample around the first winding rod 607 and the second winding rod 608 of the second clamping assembly, and rotates the third screw 606 to bring the two winding rods closer together to lock the sample. When the slider 501 starts to move linearly, the mounting plate 605 of the second clamping assembly moves synchronously with the slider 501, thereby driving the first winding rod 607 and the second winding rod 608 and the wound and locked linear fiber sample to move together, thus applying a constant speed of tension to the linear fiber sample.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
