Description

Technical Field

[0001] This utility model relates to the technical field of textile testing, specifically to a textile strength testing device. Background Technology

[0002] The main purpose of tensile strength testing for textiles is to evaluate the resistance of a drawstring to breakage under external force, ensuring its safety and reliability during use. The most common testing method is the static tensile test, in which the two ends of the drawstring are clamped by fixtures, and one set of fixtures rises at a constant speed to stretch the sample until it breaks, recording the maximum strength and tensile elongation.

[0003] Existing tensile strength testing equipment uses both automatic and manual clamps. Automatic clamps generally require auxiliary equipment, such as air pumps, while manual clamps do not require auxiliary equipment and can be used directly. A manual clamp consists of a fixed first clamp and a movable second clamp. The second clamp is horizontally strip-shaped, with both ends slidably connected to the first clamp via guide bolts. Rotating a threaded rod abuts against the center of the second clamp away from the first clamp, allowing the second clamp to move closer to the first clamp and clamp the sample. Because the threaded rod abuts against the center of the second clamp, when the second clamp is under force to hold the sample, it is not horizontally assembled with the first clamp but is tilted. This results in a higher clamping force on one side of the textile end and a lower clamping force on the other side. During tensile testing, even before the textile breaks, the tensile force exceeds the clamping force on one side of the textile end, causing partial slippage and resulting in test failure. Since the clamp is manually tightened, this problem occurs during testing when the textile's tensile breaking strength is high. Therefore, a textile strength testing device needs to be designed. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to overcome the problem in the prior art where uneven force on the ends of textile sheets leads to edge slippage and pulling when the tensile breaking strength of textiles is high.

[0005] To achieve the above objectives, this utility model provides a textile strength testing device, including a main body of the device, and further including: a pair of clamping units and auxiliary tools arranged at intervals along the vertical direction, wherein one set of clamping units is fixedly assembled on the main body of the device, and the other set of clamping units is assembled on the lifting end of the main body of the device; The clamping unit includes a first clamp and a second clamp that is horizontally connected to the first clamp via an adjustment mechanism. The second clamp has a horizontal strip groove recessed on the side near the first clamp. Several sets of sub-clamping mechanisms are arranged in the strip groove at intervals along the length of the strip groove. The auxiliary tool is matched with the adjustment mechanism and the sub-clamping mechanisms.

[0006] Preferably, the sub-clamping mechanism includes a sub-clamping slidably disposed in a strip-shaped groove, a first threaded rod rotatably connected to the sub-clamping via a bearing and threaded through the second clamping, and a first connecting member assembled on the first threaded rod away from the sub-clamping unit and adapted to an auxiliary tool, wherein the length direction of the first threaded rod is consistent with the sliding direction of the second clamping.

[0007] Preferably, one end of the sub-clamp has a recessed notch, and the other end of the sub-clamp has a protruding part that can be inserted into the notch on an adjacent sub-clamp.

[0008] Preferably, the first clamp has a first anti-slip texture on the side near the second clamp, the second clamp has a second anti-slip texture on the side near the first clamp, and the sub-clamp has a third anti-slip texture on the side near the first clamp.

[0009] Preferably, the adjustment mechanism includes a plurality of guide bolts mounted on the second clamp and slidingly passing through the first clamp, a shaft seat mounted on the first clamp, a second threaded rod with one end rotatably connected to the shaft seat and the other end threadedly passing through the second clamp, and a second connecting member mounted on the end of the second threaded rod away from the shaft seat and adapted to the auxiliary tool. A nut is fitted onto the end of the guide bolt away from the second clamp.

[0010] Preferably, both the first connector and the second connector have through holes, the length direction of which is perpendicular to the moving direction of the second clamp, and the end of the auxiliary tool has a protruding insert that can be inserted into the through hole.

[0011] Preferably, the auxiliary tool is a bending rod, and a rotating sleeve is rotatably fitted to the end of the bending rod away from the insertion rod.

[0012] According to the above technical solution, the textile strength testing device provided by this utility model has the following beneficial effects during use: After the second clamp and the first clamp work together to hold the sample, the sample ends are further clamped by the sub-clamp mechanism working with the first clamp. Several sub-clamp mechanisms are spaced apart along the length of the strip groove. Several sub-clamp mechanisms can abut against the entire end of the sample, and each sub-clamp mechanism can be adjusted individually to increase the clamping force, so as to prevent the problem of slippage due to insufficient force at the edge of the sample end.

[0016] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0017] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0018] like Figure 1-4 As shown, a textile strength testing device includes a main body and a pair of clamping units and an auxiliary tool 1 arranged at intervals along the vertical direction. One set of clamping units is fixedly mounted on the main body, and the other set of clamping units is mounted on the lifting end of the main body. The clamping unit includes a first clamp 2 and a second clamp 3 that is horizontally connected to the first clamp 2 via an adjustment mechanism. The second clamp 3 has a horizontal strip groove recessed on the side near the first clamp 2. Several sets of sub-clamping mechanisms are arranged in the strip groove at intervals along the length of the strip groove. The auxiliary tool 1 is matched with the adjustment mechanism and the sub-clamping mechanisms.

[0019] In the above technical solution, the main body of the equipment is based on existing mature technology, and generally includes a mechanical loading frame, a force measurement system, a displacement measurement system, a data acquisition and control system, and a user interface and software; the mechanical loading frame generally includes a frame, a moving crossbeam, a ball screw, and a motor; the force measurement system includes a force sensor that can accurately measure the tensile force applied to the sample; the displacement measurement system includes an encoder and an extensometer mounted on the motor or ball screw; One set of clamping units is fixedly assembled on the frame, and another set of clamping units is assembled on the moving crossbeam. The moving crossbeam drives the corresponding clamping units to move up and down. The moving crossbeam is the lifting end of the main body of the equipment. When it is necessary to clamp the sample, the adjustment mechanism is controlled by the auxiliary tool 1 to move the second clamp 3 away from the first clamp 2, insert the end of the sample between the first clamp 2 and the second clamp 3, and then move the second clamp 3 closer to the first clamp 2 to clamp the end of the sample; then the sub-clamping mechanism is controlled by the auxiliary tool 1 to match the first clamp 2 and clamp the sample tightly. The second clamp 3 cooperates with the first clamp 2 to hold the sample. However, there is uneven force during clamping, and the edge of the sample end may slip between the first clamp 2 and the second clamp 3 during testing. Therefore, a sub-clamp mechanism is used to cooperate with the first clamp 2 to further clamp the end of the sample. Several sub-clamp mechanisms are spaced apart along the length of the strip groove. Several sub-clamp mechanisms can abut against the entire end of the sample, and each sub-clamp mechanism can be adjusted individually to increase the clamping force, so as to prevent the problem of slippage due to insufficient force on the edge of the sample end.

[0020] In a preferred embodiment of the present invention, the sub-clamp mechanism includes a sub-clamp 4 slidably disposed in a strip-shaped groove, a first threaded rod 5 rotatably connected to the sub-clamp 4 via a bearing and threadedly passing through the second clamp 3, and a first connecting member 6 assembled on the first threaded rod 5 away from the sub-clamp 4 unit and adapted to the auxiliary tool 1, wherein the length direction of the first threaded rod 5 is consistent with the sliding direction of the second clamp 3.

[0021] In the above technical solution, connecting the auxiliary tool 1 to the first connecting piece 6 can drive the first threaded rod 5 to rotate, thereby driving the sub-clamp 4 to move closer to or further away from the first clamp 2 in the strip groove.

[0022] In a preferred embodiment of the present invention, a notch 7 is recessed on one end of the sub-clamp 4, and a protrusion 8 is protruding on the other end of the sub-clamp 4, which can be inserted into the notch 7 on an adjacent sub-clamp 4.

[0023] In the above technical solution, the protrusion 8 on the sub-clamp 4 can be inserted into the notch 7 on the adjacent sub-clamp 4. When clamping the sample, the clamping force can be applied to all the warp or weft threads, which can prevent the warp or weft threads not clamped by the sub-clamp 4 from affecting the accuracy of the test results due to insufficient clamping force.

[0024] In a preferred embodiment of the present invention, the first clamp 2 is provided with a first anti-slip texture on the side near the second clamp 3, the second clamp 3 is provided with a second anti-slip texture on the side near the first clamp 2, and the sub-clamp 4 is provided with a third anti-slip texture on the side near the first clamp 2.

[0025] In the above technical solution, the first anti-slip texture, the second anti-slip texture, and the third anti-slip texture can all improve the clamping force and further reduce the probability of the sample end being pulled out.

[0026] In a preferred embodiment of the present invention, the adjustment mechanism includes a plurality of guide bolts 9 mounted on the second clamp 3 and slidingly passing through the first clamp 2, a shaft seat 12 mounted on the first clamp 2, a second threaded rod 10 with one end rotatably connected to the shaft seat 12 and the other end threadedly passing through the second clamp 3, and a second connecting member 11 mounted on the end of the second threaded rod 10 away from the shaft seat 12 and adapted to the auxiliary tool 1. The end of the guide bolt 9 away from the second clamp 3 is fitted with a nut.

[0027] In the above technical solution, by connecting the auxiliary tool 1 to the second connecting member 11 and driving the second threaded rod to rotate, the second clamp 3 can be moved closer to or away from the first clamp 2.

[0028] In a preferred embodiment of the present invention, both the first connector 6 and the second connector 11 are provided with through holes 13. The length direction of the through holes 13 is perpendicular to the moving direction of the second clamp 3. The end of the auxiliary tool 1 has a protruding insert part 14 that can be inserted into the through hole 13.

[0029] In the above technical solution, when the auxiliary tool 1 needs to be connected to the first connector 6 or the second connector 11, the insertion rod 14 is inserted into the through hole 13, and the first threaded rod 5 or the second threaded rod 10 can be rotated by the auxiliary tool 1.

[0030] In a preferred embodiment of this utility model, the auxiliary tool 1 is a bending rod, and a rotating sleeve 15 is rotatably fitted to the end of the bending rod away from the insertion rod portion 14.

[0031] In the above technical solution, holding the rotating sleeve 15 drives the auxiliary tool 1 to rotate. The rotating sleeve 15 facilitates the use of the auxiliary tool 1 and can avoid friction between the auxiliary tool 1 and the palm.

[0032] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0033] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0034] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
