[0063] Reference Figures 1-6 In a first aspect of the present invention, a multifunctional textile tensile tester is provided, comprising a platform 1 and a clamping assembly 2. Two sides of the platform 1 are provided with uprights 11 and are equipped with first displacement drive components 12. A crossbeam 121 is connected between two sets of first displacement drive components 12, and can move relative to each other along the length direction of the uprights 11. The ability of the crossbeam 121 to move along the uprights 11 enables it to adjust its vertical position according to test requirements and accommodate textile samples of different specifications. During the tensile test, the up and down movement of the crossbeam can preset the initial stretching distance or adjust the clamp spacing to meet different standards.

[0064] A tension detection component 3 is provided on the crossbeam 121. The tension detection component 3 adopts a tension sensor with a communication function in the prior art. The tension sensor is a known technology. The installation and connection relationship will not be described in detail here. The clamp component 2 is provided with two groups, one of which is located on the machine 1 and the other is connected to the tension detection component 3. The tension detection component 3 is directly integrated into the crossbeam 121, which can measure the stress change in the stretching process in real time and synchronously, reduce the error of the transmission link, and ensure the accuracy of the data. The two groups of clamp components 2 are respectively fixed to the machine 1 and the tension detection component 3, forming a "bottom-fixed and top-pulling" stretching mode;

[0065] A support seat 13 is further provided on one side of the machine 1 and is installed with a second displacement driving component 14. The second displacement driving component 14 includes a bearing seat 141. The bearing seat 141 can move relatively along the length direction of the support seat 13. A first push rod component 4 is vertically provided on the side of the bearing seat 141 facing the clamp component 2. The piston end of the first push rod component 4 is connected to a receiving portion 41. The receiving portion 41 has a mounting hole 411 and is movably mounted with a friction test component 5 or a bursting test component 6. The friction test component 5 includes a disc 51, and the bursting test component 6 includes a push rod 61. By replacing the friction test component 5 or the bursting test component 6, multiple tests such as tensile, friction, and bursting can be completed on one device.

[0066] A slide groove 15 is provided on the machine 1, and a second push rod component 16 is provided in the slide groove 15. The piston end of the second push rod component 16 is connected to a slider 161 and is connected to one group of clamp components 2. Through the cooperation of the second push rod component 16, the two groups of clamp components 2 are parallel or staggered with each other.

[0067] Based on the above structure, the two ends of the textile to be tested are respectively placed on the clamp components 2. Since one group of the clamp components 2 is connected to the beam portion 121 through the tension detection component 3, the first displacement driving component 12 can drive one group of the clamp components 2 to move, while the other group remains fixed in position. Therefore, when the beam portion 121 moves, the textile can be stretched, and the tension detection component 3 can detect the tension generated by the pulling, so as to analyze the tensile properties of the textile. In addition, the second displacement driving component 14 provided on the bracket seat 13 can drive the bearing seat 141 to move. The first push rod component 4 provided on the bearing seat 141 is installed with the bursting test component 6 and the friction test component 5 through the receiving portion 41. The textile can be pulled to be tightened by the tension detection component 3.

[0068] When abrasion resistance or color fastness testing is required, the second displacement driving component 14 drives the supporting base 141 to move to a designated position, and drives the disc 51 in the friction test component 5 to move via the first push rod component 4. The disc 51 has a friction cloth on it. When the friction cloth abuts against the placed product and moves back and forth in cooperation with the second displacement driving component 14, the friction test of the textile can be completed.

[0069] When a bursting pressure test is required, the second displacement driving component 14 drives the bearing seat 141 to move to a specified position, and drives the push rod 61 in the bursting test component 6 to move through the first push rod component 4, thereby applying lateral pressure to the textile. The bursting time of the textile is then tested by the extension and contraction length and time of the first push rod component 4. The cooperation between the second displacement driving component 14 and the first push rod component 4 can realize bursting and friction tests, thereby achieving multifunctional testing on a single device, solving the problem that existing tensile testers can only perform a single tensile test, resulting in the need for multiple different devices for multiple tests, making it difficult to evaluate the overall durability and fatigue life of the fabric.

[0070] The above-mentioned first push rod component 4 and second push rod component 16 adopt pneumatic push rods in the prior art, and the pneumatic push rods are connected to the external air pump through pipelines. The first motor 123 and the second motor 143 both adopt servo drive motors in the prior art. The installation and connection relationship are well known to people in this field, so they will not be described in detail here.

[0071] In one embodiment, referring to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 A first mounting shaft 52 is provided on one side of the disc body 51 , and the receiving portion 41 is connected to the disc body 51 by embedding the first mounting shaft 52 into the mounting hole 411 ;

[0072] The disc 51 has a convex disc portion 511 for carrying the friction cloth. A frame 53 is movably mounted on one side of the disc 51. The disc 51 has a slot 512. A block 531 is provided on the frame 53 at a position corresponding to the slot 512. The slot 512 and the block 531 cooperate to allow the frame 53 to be mounted on the disc 51 to fix the friction cloth. The first mounting shaft 52 is embedded in the mounting hole 411 to provide a simple and stable connection between the receiving portion 41 and the disc 51. The frame 53 is mounted on the disc 51 through the slot 512 and the block 531. After the block 531 is embedded in the slot 512, it can effectively limit the movement of the frame 53 in the horizontal and vertical directions, thereby firmly fixing the friction cloth on the convex disc portion 511.

[0073] When the frame 53 is located on the disc 51 , the convex disc portion 511 is located outside the frame 53 . The arrangement of the convex disc portion 511 can prevent the friction cloth from being limited or colliding when in contact with the textile.

[0074] In one embodiment, referring to Figure 1 、 Figure 3 and Figure 4 The top rod 61 consists of a second mounting shaft 611 and a top ball 612. The top ball 612 is arranged on the second mounting shaft 611. Through the cooperation of the second mounting shaft 611 and the mounting hole 411, the top ball 612 is moved close to or away from between the two groups of clamping parts under the cooperation of the first push rod component 4. The top ball 612 is installed on the receiving portion 41 through the second mounting shaft 611. With the help of the push or pull of the first push rod component 4, it can reciprocate between the two groups of clamping parts. When the textile needs to be tensile tested, the top ball 612 can be close to the clamp component 2 under the action of the first push rod component 4, and exert a top pressure on a specific position of the textile, thereby causing the textile to break. At the same time, the spherical design of the top ball 612 makes it a point contact when it contacts the textile, which can reduce damage to the surface of the textile compared to plane contact.

[0075] In one embodiment, referring to Figure 1 、 Figure 6 、 Figure 7 and Figure 8 The disc body 51 has a receiving cavity 513, and the convex disc portion 511 is provided with a slot extending into the receiving cavity 513. The slots are provided with a plurality of intervals and are located inside the disc body 51 to form a cavity to provide a moving space for the cutting component 7. The surface of the convex disc portion 511 is provided with a plurality of slots extending into the receiving cavity 513. The spacing and size of the slots correspond to the layout of the tip portion 72. At the same time, the width of the slot is slightly larger than the diameter of the tip portion 72 to ensure that the tip portion 72 can pass freely without generating excessive gaps.

[0076] A scratching component 7 is provided in the accommodating cavity 513. The scratching component 7 can be used to scratch the textile, thereby determining the scratch resistance of the textile. The scratching component 7 includes a support 71 that is movably disposed in the accommodating cavity 513. The support 71 has several pointed portions 72 disposed at positions corresponding to the slots.

[0077] By moving the support 71 in the accommodating chamber 513, part of the tip portion 72 passes through the slot and is located outside the convex disc portion 511 or inside the accommodating chamber 513. By moving the support 71 in the accommodating chamber 513, the scratching component 7 can have a detection state and a retracted state. When in the detection state, the support 71 moves so that the tip of the tip portion 72 is located outside the convex disc portion 511, and is directed toward the textile with the cooperation of the first push rod component 4. At the same time, the textile is reciprocated with the cooperation of the second displacement driving component 14, thereby forming scratches, thereby judging the scratch resistance of the textile at the same distance or frequency. At the same time, when the scratching component 7 is in the retracted state, the support 71 drives the tip portion 72 to be located in the accommodating chamber 513, thereby preventing the tip portion 72 from damaging the textile when it is not needed.

[0078] In one embodiment, referring to Figure 1 、 Figure 2 、 Figure 6 、 Figure 8 and Figure 11 The top of the tray body 51 is provided with a through slot 514 extending into the accommodating cavity 513. The top of the support 71 is provided with a protrusion passing through the through slot 514 and is installed with a support plate 711. The support plate 711 is located outside the tray body 51. The operator can move the support 71 by moving the support plate 711.

[0079] The support plate 711 is provided with a limiting hole 7111, and one side of the disk body 51 is provided with several fixing holes 515 matching the limiting holes 7111. By moving the support 71, the limiting holes 7111 are aligned with one group of fixing holes 515 and a pin shaft is movably installed. Since multiple fixing holes 515 are provided on one side of the disk body 51, the limiting holes 7111 on the support plate 711 can be aligned with the fixing holes 515 at different positions by moving the support 71, thereby realizing the fixation of the stripping component 7 at different positions in the accommodating cavity 513. When the limiting holes 7111 are aligned with the fixing holes 515 and the pin shaft is inserted, the support 71 is firmly fixed in the accommodating cavity 513 and will not be displaced due to force during the stripping process, thereby ensuring the stability and reliability of the stripping operation.

[0080] In one embodiment, referring to Figure 1 、 Figure 2 、 Figure 5 and Figure 10The fixture component 2 includes a fixed seat 21, which has an opening 211. Turntable members 212 are rotatably provided on both sides of the opening 211. The turntable members 212 are connected to the fixed seat 21 through a shaft, so that they can achieve circular rotation. The outside of one group of turntable members 212 is connected to a handle member through a shaft. A mounting cylinder 22 is connected between the two groups of turntable members 212. When one group of turntable members 212 rotates, the other group rotates synchronously with the cooperation of the mounting cylinder 22.

[0081] The mounting cylinder 22 is provided with a slot 221 which passes through the mounting cylinder 22. The slot 221 is used for the passage of textiles. The two sets of turntable members 212 cooperate to make the mounting cylinder 22 rotate in a circle. When the textile passes through the slot 221, its edge is limited by the side walls or bottom curved surface of the slot 221. When the mounting cylinder 22 rotates, the slot 221 moves accordingly. If the textile moves in a circle with the mounting cylinder 22, it will be subjected to the centripetal force, causing the fabric to be tightened and fit against the inner wall of the slot 221, forming a passive clamp. When the mounting cylinder 22 continues to rotate, the textile is driven by the slot 221 to move in a circle, and its movement trajectory is limited within the range of the opening 211 of the fixing seat 21, and it cannot escape to the outside. Even if it is subjected to pulling force, the centrifugal force or restraint force generated by the rotation will further tighten the fabric, thereby enhancing the clamping effect.

[0082] In one embodiment, referring to Figure 1 、 Figure 2 、 Figure 5 and Figure 10 An elastic clamping component 8 is provided in the slot 221. The elastic clamping component 8 includes an elastic member 81. The elastic member 81 adopts a pressure spring or a telescopic spring in the prior art. A plurality of elastic members 81 are provided and spaced apart along the length direction of the slot 221. One end of the elastic member 81 is connected to the inner wall of the slot 221, and the other end is connected to the clamping plate 82.

[0083] A clamping area is formed between the clamping plate 82 and the slot 221. The setting of the elastic member 81 enables the clamping plate 82 to have a certain elastic displacement ability. When the textile is placed in the clamping area, the clamping plate 82 gently clamps the textile under the action of the elastic member 81, which can not only ensure that the textile will not slide due to insufficient clamping force during the stretching process, but also avoid indentation or damage to the textile due to excessive clamping force. For textiles of different thicknesses, the clamping plate 82 will move accordingly under the action of the elastic member 81, always maintaining effective clamping of the textile, and further improving the clamping ability of the clamp component.

[0084] In one embodiment, referring to Figures 1-4, the first displacement driving component 12 also includes a first screw rod 122, which is rotatably arranged in the column 11, and a screw support seat is provided at the connection between the first screw rod 122 and the column 11. A first motor 123 is provided at the position corresponding to the column 11 in the machine 1, and the output end of the first motor 123 is connected to the first screw rod 122 through a coupling. The two ends of the beam 121 are respectively mounted on the first screw rod 122, and a bearing is provided at the connection between the beam 121 and the first screw rod 122 and the second screw rod 142. The first motor 123 and the second motor 143 respectively drive the first screw rod 122 and the second screw rod 142 to rotate, and the rotational motion of the motor is converted into the linear motion of the beam 121 and the bearing seat 141 through the screw nut transmission principle, so that the displacement of the beam 121 and the bearing seat 141 can be accurately controlled to meet the requirements for the position accuracy of the clamping component in the textile tensile test;

[0085] The second displacement drive component 14 also includes a second screw member 142, which is rotatably arranged in the bracket seat 13. A screw support seat is provided at the connection between the second screw member 142 and the bracket seat 13. A second motor 143 is provided at a position corresponding to the bracket seat 13 in the machine 1. The output end of the second motor 143 is connected to the second screw member 142 through a coupling, and the bearing seat 141 is installed on the second screw member 142.

[0086] In one embodiment, referring to Figures 1-4 , further comprising a console 9, the console 9 being located on one side of the machine 1, and having a controller therein, the controller being a PLC controller in the prior art, having programmable control capability, the controller being electrically connected to the first motor 123 and the second motor 143, and being used to control the operation of the first motor 123 and the second motor 143;

[0087] The controller is communicatively connected with the tension detection component 3 and can receive the tension data detected by the tension detection component 3 in real time. The controller is connected with the first push rod component 4 and the second push rod component 16. The console 9 serves as the control center of the entire tester. The controller realizes centralized control and data collection of various driving components such as the first motor 123, the second motor 143, the push rod components such as the first push rod component 4, the second push rod component 16 and the detection components such as the tension detection component 3 through electrical and communication connections. Through a preset control program, the controller can automatically control the operation process of the tester.

[0088] In one embodiment, referring to Figure 1 and Figure 9, guide protrusions 151 are provided on both sides of the slide groove 15, and grooves 1611 are provided at the positions of the slider 161 corresponding to the guide protrusions 151. When the slider 161 is located in the slide groove 15, the guide protrusion 151 is embedded in the groove 1611, and the T-shaped or dovetail structure of the guide protrusion 151 cooperates with the groove 1611 to limit the lateral and vertical displacement of the slider 161 and the rotation around the three axes, retaining only the linear movement along the direction of the slide groove 15, ensuring that the clamping component or the push rod component has no offset when moving at high speed. The design of the guide protrusion 151 and the groove 1611 usually adopts a smooth surface and a reasonable matching clearance, which can reduce the friction resistance between the slider 161 and the slide groove 15, reduce the wear between the components, and extend the service life of the equipment.

[0089] In a second aspect of the present invention, a multifunctional textile stretch detection method is provided, comprising the following steps:

[0090] S1. Clamp the two ends of the textile between the two sets of clamp components 2 respectively, and use the first displacement driving component 12 to drive the crossbeam 121 to move relative to each other, so that the two ends of the textile gradually move away from each other until they break;

[0091] S2, replace the textile and re-clamp it in the clamp part 2;

[0092] S3. The first displacement driving component 12 drives the crossbeam 121 to move so that the textile is taut. At the same time, the second displacement driving component 14 and the first push rod component 4 cooperate to make the friction test component 5 abut against the end surface of the textile and perform reciprocating movement to rub the textile in cooperation with the second displacement driving component 14.

[0093] S4, replace the textile and re-clamp it in the clamp part 2;

[0094] S5. The first displacement driving component 12 drives the crossbeam 121 to keep the textile taut. Meanwhile, the second displacement driving component 14 and the first push rod component 4 cooperate to change the position of the bursting test component 6 until the push rod 61 bursts the textile.
