Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, specifically a tensile strength testing device for fabric production. Background Technology

[0002] In the field of fabric production and quality inspection, tensile strength and bursting strength are key indicators for evaluating the physical properties of fabric.

[0003] An existing patent (publication number: CN218726108U) discloses a fabric tensile strength testing machine with fabric smoothing function, relating to the field of fabric tensile strength testing technology. It includes a base, a clamping mechanism at the upper end of the base, and a smoothing mechanism at the upper end of the base. This invention solves the problem that existing fabric tensile strength testing machines often leave numerous wrinkles on the fabric after testing, making it difficult to smooth out wrinkles in fabrics that meet tensile strength standards after testing. This leads to the fabric easily affecting production quality in later processes due to surface wrinkles. This invention, through the arrangement of a clamping mechanism, clamping blocks, a long rod, a second collar, a threaded rod, a smoothing mechanism, and an ironing plate, achieves the fixation of both ends of the fabric by the clamping blocks and the testing of the fabric's tensile strength. Compared to manually fixing the fabric, this is more secure. The ironing plate smooths both sides of the fabric, preventing surface wrinkles from affecting subsequent operations.

[0004] However, when testing fabric samples, it is necessary to test not only their tensile properties but also their bursting strength. The aforementioned device can only test tensile properties, and different equipment is required for tensile and bursting strength tests, which increases the complexity and time cost of operation and reduces its functionality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tensile strength testing device for fabric production, which has advantages such as high functionality and solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tensile strength testing device for fabric production, comprising a testing platform, a lifting frame fixedly connected to the upper surface of the testing platform, a lifting block slidably connected inside the lifting frame, a fixed frame fixedly connected to the front of the lifting block, a switching shaft rotatably connected to the front end of the fixed frame, a switching plate fixedly connected to the front end of the switching shaft, and a top component provided on the front of the switching plate;

[0007] An adjustment plate is slidably connected to the upper surface of the testing station, and a bottom component is provided on the upper surface of the adjustment plate.

[0008] Furthermore, the top assembly includes a top rod and a top screw. One end of the top rod is fixedly connected to the top front of the switching plate, and the other end of the top rod is fixedly connected to a top ball. The top screw is rotatably connected to the bottom front of the switching plate. A top clamping plate is threadedly connected to the outer surface of the top screw. A limit rod is slidably inserted into the top of the top clamping plate, and one end of the limit rod is fixedly connected to the switching plate.

[0009] The above scheme can achieve the purpose of applying pressure to the test sample when testing the bursting strength, and the top clamp can be used to fix the top of the test sample during the tensile test.

[0010] Furthermore, the bottom assembly includes a pressure sensor and a tension sensor, which are respectively installed at both ends of the adjustment plate. The detection end of the pressure sensor is mounted on a chassis, and a set of support columns are fixedly connected to the upper surface of the chassis. The top of the set of support columns is fixedly connected to the same placement cylinder. A pressure column is threaded inside the placement cylinder, and a test hole penetrating the bottom of the placement cylinder is opened at the top of the pressure column. A U-shaped clamp is installed at the detection end of the tension sensor, and a bottom screw is threadedly connected to the front of the U-shaped clamp. The rear end of the bottom screw is rotatably connected to the bottom clamp, and the bottom clamp is slidably connected to the inner bottom wall of the U-shaped clamp.

[0011] The above scheme allows for monitoring of tensile force when the sample is pulled using a tensile sensor, and monitoring of pressure when the burst strength is tested using a pressure sensor.

[0012] Furthermore, a first lead screw is rotatably connected between the inner top wall and the inner bottom wall of the lifting frame, the lifting block is threadedly connected to the first lead screw, and a motor is installed at the top of the lifting frame, with the output end of the motor fixedly connected to the top of the first lead screw.

[0013] The above scheme, through the setting of the first lead screw, enables the lifting block to move up and down.

[0014] Furthermore, a first motor is mounted on the upper surface of the fixing frame, and the output end of the first motor is fixedly connected to one end of the switching shaft.

[0015] The above scheme allows for the adjustment of the position of the top ball or top clamp by driving the switching shaft with the first motor, thus facilitating different test items.

[0016] Furthermore, a second lead screw is rotatably connected to one side of the inner wall of the testing platform, the bottom of the adjusting plate is threadedly connected to the second lead screw, and a second motor is fixedly installed on the inner wall of the testing platform, with the output end of the second motor fixedly connected to one end of the second lead screw.

[0017] The above scheme, through the setting of the second motor, enables the adjustment of the position of the adjustment plate.

[0018] Furthermore, the bottom of the testing platform is equipped with a set of adjustable support feet.

[0019] The above solution, with its adjustable support feet, ensures the levelness of the testing platform.

[0020] Furthermore, a control host is installed on the upper surface of the testing station.

[0021] The above scheme, through the configuration of the control host, makes it easy for testers to control electrical components and read data.

[0022] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

At the same time, the design of the top and bottom clamps can firmly fix the test sample, preventing slippage or detachment during the test, further improving the accuracy of the test.

[0037] Please see Figure 1 , Figure 2 and Figure 5 The top assembly 7 includes a top rod 701 and a top screw 702.

[0039] This embodiment of a fabric production tensile strength testing device integrates tensile strength testing and bursting strength testing into one unit.

[0040] The working principle of the above embodiment is as follows: If a tensile strength test is selected, the tester starts the first motor 13 through the control host 16. The first motor 13 drives the switching shaft 5 to rotate, so that the top clamping plate 704 in the top assembly 7 is aligned with the sample. At the same time, by adjusting the second motor 17, the U-shaped clamping plate 908 and the bottom clamping plate 910 in the bottom assembly 9 are moved to the appropriate position and clamp the other end of the sample. At this time, the tensile sensor 902 starts to work. The tester starts the motor 12 through the control host 16. The motor 12 drives the first lead screw 11 to rotate, so that the lifting block 3 and the top clamping plate 704 descend, aligning with the sample. When a tensile force is applied to the sample, the tensile sensor 902 monitors the changes in tensile force in real time and transmits the data to the control host 16. If the bursting strength test is selected, the tester adjusts the switching shaft 5 through the control host 16 so that the top ball 703 in the top assembly 7 is aligned with the sample. At the same time, by adjusting the second motor 17, the pressure sensor 901 and the chassis 903 in the bottom assembly 9 are moved to the appropriate position. At this time, the tester starts the motor 12, which drives the lifting block 3 and the top ball 703 to descend and apply pressure to the sample. The pressure sensor 901 monitors the pressure changes in real time and transmits the data to the control host 16.
