[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0043] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention 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 understood as a limitation on the present invention.

[0044] Example:

[0045] Reference Figure 1 - Fig. 9 A textile strength testing device includes a substrate 1, and also includes: stretching arms 3 fixedly installed on both sides of the upper part of the substrate 1, the two stretching arms 3 clamp the textile and perform a moving away action to realize a stretching testing action, wherein the stretching arms 3 are provided with a pneumatic spring adjustment system, and the pneumatic spring adjustment system performs an initial adaptive tension adjustment when the two stretching arms 3 perform a moving away action to realize an initial tight state adjustment before the textile stretch test.

[0046] The above-mentioned textile strength testing equipment solves the problem of complex implementation of the tension structure of the manually adjusted tension device in traditional technology by first placing the textile in the clamping part of the two stretching arms 3 for clamping during the tensile test, and then using a pneumatic tool to perform an automatic tensile test. It also proposes a pneumatic spring adjustment system, which acts on the stretching arm 3 so that the stretching arm 3 can be adaptively adjusted. When the two stretching arms 3 move away, the textile is tightened, and the pneumatic tool of the pneumatic spring adjustment system controls the stretching arms 3 to move away and elastically pulls the textile, which solves the problem in traditional technology that the operator has to pull the textile tight after putting the textile into the clamping part of the two stretching arms 3 and moving it back, and is used to reduce the movement stroke of the stretching arm 3 and perform adaptive adjustment.

[0047] In order to realize the driving of the stretching arm 3, preferably, mounting seats 6 are fixedly installed on both sides of the upper part of the substrate 1, and the cylinder 2 fixedly installed inside the two mounting seats 6 is symmetrically arranged on the substrate 1, and the output end of the cylinder 2 is fixedly connected to the stretching arm 3. The stretching arm 3 is driven by the cylinder 2 to perform a lateral movement, and the lower part of the stretching arm 3 slides and fits with the substrate 1.

[0048] When the stretching arm 3 is driven, the pneumatic unit in the pneumatic spring adjustment system is the cylinder 2, which is fixed in the mounting seat 6 on the substrate 1. When the textile is pulled and tested, the two stretching arms 3 are controlled to move away from the stretching action through two starts. In order to realize the adaptive adjustment of the pneumatic spring adjustment system, the elastic pulling member 301 is the main part of the pneumatic spring adjustment system. Furthermore, the stretching arm 3 includes an elastic pulling member 301, which is fixed at the output end of the cylinder 2. A tension detector 302 for connecting and communicating with the detection system of the detection equipment is fixedly installed on the side of the elastic pulling member 301 away from the cylinder 2, and a connecting seat 303 is fixedly installed on the side of the tension detector 302 away from the elastic stretching member. In other words, the pneumatic spring adjustment system is composed of the cylinder 2 and the elastic pulling member 301.

[0049] In order to realize the detection of tension, the tension detector 302 is integrated and installed in the stretching arm 3. Specifically, the tension detector 302 is fixed between the elastic pulling member 301 and the connecting seat 303, so that the tension detector 302 can perform real-time tension detection, and when no textile is placed, perform operations such as parameter zeroing, and then the tension detector 302 transmits the real-time data of tension to the detection system of the detection equipment, thereby completing the real-time monitoring and recording of the data of textile stretch detection.

[0050] In order to realize the detection of tension and adaptive pulling of textiles, the elastic pulling member 301 further includes a first fixed tube 3011, which is fixed at the end of the cylinder 2. The first fixed tube 3011 is connected to the first piston rod 3013 through a spring 3012. The first piston rod 3013 is slidably installed in the first fixed tube 3011, and the end of the first piston rod 3013 away from the cylinder 2 is fixedly connected to a connecting seat 303.

[0051] To achieve adaptive adjustment, when the two stretching arms 3 pull the textile for initial stretching, the spring 3012 is first deformed by the tension. At this time, the textile is taut and the spring will not be torn apart, which is used for adaptive flattening of the textile. Further, when conducting formal testing, the purpose of reducing the moving stroke of the stretching arm 3 is achieved, and useless data recorded due to textile relaxation is reduced, that is, the stage data in which the tension of the stretching arm 3 is continuously zero within a certain stroke.

[0052] In order to realize the pneumatic clamping of the textile, the testing device further includes a pneumatic clamp 4, which includes a support seat 401, a support seat 401 is fixedly installed on the side of the connection seat 303 away from the elastic stretching member, a fixed clamp 403 is fixedly installed on one side of the support seat 401 through a first screw 402, and a movable clamp 404 is also slidably installed on the same side of the fixed clamp 403 on the support seat 401, and the movable clamp 404 approaches the fixed clamp 403 to perform a clamping action. In order to realize the pneumatic control action of the movable clamp 404, a gas flow channel is preset, and further, a pneumatic part 405 is fixedly installed inside the fixed clamp 403, and the end of the telescopic unit of the pneumatic part 405 is fixedly connected to the movable clamp 404, an air channel 409 is opened inside the support seat 401, and a first air seat 406 is fixedly connected to one side of the support seat 401, and the first air seat 406 is connected with the pneumatic part 405 through the air channel 409.

[0053] In order to achieve stable clamping of the textile, the pneumatic part 405 further includes a second fixed tube 4051, which is fixed inside the fixed clamp 403, and a pneumatic second piston rod 4052 is slidably installed inside the second fixed tube 4051. The end of the second piston rod 4052 is fixedly connected to the movable clamp 404, and the second contact plate 408 and the first contact plate 407 are respectively fixedly installed on one side of the fixed clamp 403 and the movable clamp 404 through the second screw 411, and a guide plate 410 is fixedly installed on one side of the support seat 401 through the first screw 402, and the guide plate 410 is in sliding contact with the inner wall of the movable clamp 404. In order to realize pneumatic control of the movable splint 404, further, a pneumatic component 5 is provided on the upper part of the substrate 1, and the pneumatic component 5 includes a fixed plate 501, and the fixed plate 501 is fixed on the upper part of the substrate 1, and an air cavity is provided inside the fixed plate 501, and the input end of the micro air pump 503 fixed on the substrate 1 is connected with the air cavity of the fixed plate 501 through the first air pipe 502, and the input end of the diverter plate 504 fixed on the upper part of the substrate 1 is fixedly connected with the output end of the micro air pump 503 through the second air pipe 505, and the two output ends of the diverter plate 504 are connected with the first air seat 406 through the third air pipe 506 respectively.

[0054] When the textile is clamped, the clamping assembly is first controlled to open, and the detection system starts the micro air pump 503. At this time, the micro air pump 503 performs a pumping action, thereby controlling the third piston rod 5012 to move away from the air port 5013. At the same time, air is taken in through the air hole, and the gas in the plate body 5011 is extracted by the micro air pump 503 through the second air seat 5014 and the first air pipe 502. The micro air pump 503 then transmits the gas to the diverter plate 504 through the second air pipe 505 for diversion. The diverter plate 504 then transmits the gas to the first air seat 406 through the two third air pipes 506 for the two pneumatic parts 405. Specifically, the first air seat 406 receives the gas. The gas is collected and transmitted to the second fixed tube 4051 through the air channel 409 of the support seat 401. At this time, the second piston rod 4052 is pushed out by the air pressure to control the movable splint 404 to move away from the fixed splint 403. Then, when clamping, the micro air pump 503 transmits the gas to the inside of the plate body 5011, and the second piston rod 4052 controls the movable splint 404 to move close to the fixed splint 403. At this time, the first contact plate 407 and the second contact plate 408 move close to each other to complete the pneumatic clamping of the textile. At the same time, the inner walls of the first contact plate 407 and the second contact plate 408 are provided with transverse anti-slip grooves to ensure that the textile will not fall off when stretched.

[0055] In order to realize the control of the door panel 8 opening when the start clamp is opened, and then the textile is unloaded, the fixed plate 501 further includes a plate body 5011, the plate body 5011 is hollow, a third piston rod 5012 is slidably installed inside the plate body 5011, an air port 5013 is opened on the upper part of one side of the plate body 5011, a second air seat 5014 is fixedly connected to the upper part of the plate body 5011, the inner cavity of the plate body 5011 is connected to the first air pipe 502 through the second air seat 5014, and a third piston rod 5012 is slidably installed inside the plate body 501 ... A feeding chute 7 is used to collect the pulled textile fabrics, and a door panel 8 is rotatably installed inside the feeding chute 7. The door panel 8 is connected to the fixed plate 501 through a transmission assembly 9. The transmission assembly 9 includes a linkage rod 901. The linkage rod 901 is fixed to one end of the rotating shaft of the door panel 8. The linkage rod 901 is rotatably installed inside the base plate 1. One end of the linkage rod 901 passes through the base plate 1 and is fixedly connected to a gear 902. The gear 902 is meshedly connected to a tooth plate 903. The slide plate fixed to the end of the third piston rod 5012 is fixedly connected to the tooth plate 903.

[0056] In order to realize the automatic collection and processing of the stretched textile waste, the door panel 8 is linked with the pneumatic system of the clamp. Specifically, when the micro air pump 503 controls the second piston rod 4052 to move, and then controls the first contact plate 407 and the second contact plate 408 to approach, at this time, the second piston rod 4052 body is close to the side of the air port 5013, and the driving slider 904 drives the tooth plate 903 to move. When the tooth plate 903 moves, the driving gear 902 rotates, and then drives the linkage rod 901 to rotate, and controls the door panel 8 to open downward, so that when the new textile is clamped, the tested textile falls. When it is installed and used, the substrate 1 is installed overhead on the upper part of the collection box or the conveyor to collect or convey the tested textile for the next step of taking pictures to identify the wound at the textile break. When the micro air pump 503 controls the first contact plate 407 and the second contact plate 408 to move away, the tooth plate 903 is reset, and the door panel 8 re-blocks the unloading port of the substrate 1 to realize orderly unloading.

[0057] A textile strength testing method comprises the following steps:

[0058] Step 1: Take out the textile to be tested, and put both ends into the clamping position of the stretching arm 3 for preliminary clamping;

[0059] Step 2: Control the two stretching arms 3 to initially move away from each other, and use the pneumatic spring adjustment system to make the stretching arms 3 put the textile in an elastically stretched and taut state;

[0060] Step 3: Continue to control the two stretching arms 3 to move away until the textile breaks, record the stretching force, and complete the test.

[0061] In the present invention, when performing a tensile test, the textile is first placed on the clamping parts of the two stretching arms 3 for clamping, and then an automatic tensile test is performed using a pneumatic tool, thereby solving the problem of complex implementation of the tension structure of the manually adjusted tension device in the traditional technology; when the two stretching arms 3 move away, the textile is stretched taut, and the pneumatic tool of the pneumatic spring adjustment system controls the stretching arms 3 to move away and elastically pulls the textile, thereby solving the problem in the traditional technology that the operator has to pull the textile taut after putting the textile into the clamping parts of the two stretching arms 3 and moving them backwards, and adaptive adjustment is performed for the purpose of reducing the movement stroke of the stretching arms 3.
