[0002] Chemical fiber is an artificially synthesized fiber material. Through chemical reactions, simpler compounds are transformed into more complex molecular structures, thereby forming fibers with specific properties and morphologies. Chemical fiber fabrics have the advantages of being light, warm, durable, and wrinkle-resistant. Polyester fabric is a very commonly used chemical fiber clothing fabric in daily life, which has the advantages of good wrinkle resistance and shape retention, and is suitable for making outdoor products such as outerwear, various types of luggage, and tents. Before production and processing, the tensile strength performance of polyester fabric needs to be detected.

[0003] Chinese Patent Authorization Publication No.: CN220356851 U discloses a device for detecting the tensile strength of polyester fabric. By placing the fabric on the top of the first lower clamping plate and the second lower clamping plate for wiring and fixing, the second cylinder contracts to drive the fabric to stretch and deform. Under the action of the tensile force sensor, the strength value can be automatically detected and displayed in real time on the display screen, which is convenient for detecting the tensile strength of polyester fabric.

[0004] For the tensile strength of the same fabric, multiple detections are often required to ensure accuracy. In the above solution, only one fabric can be detected for tensile strength at a time. After detection, the fabric needs to be removed and a new fabric needs to be fixed again before it can be detected again.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following further describes the present utility model in detail:

[0025] As Figures 1 to 5 shown, the present utility model provides a device for detecting the tensile strength of chemical fiber fabrics, including a base 1, a stretching assembly 3, a first fixture 4 and a second fixture 5. A plurality of guide grooves 2 are equidistantly opened at the top of the base 1. The stretching assembly 3 is fixedly installed on the left side of the top of the base 1. A plurality of first fixtures 4 and second fixtures 5 are arranged according to the positions of the guide grooves 2. The first fixture 4 is fixedly installed on the right side of the top of the base 1, and the second fixture 5 is fixedly installed inside the stretching assembly 3. The positions of the guide grooves 2, the first fixture 4 and the second fixture 5 correspond to each other;

[0026] The stretching assembly 3 includes a plurality of guide rods 31 fixedly connected in the guide grooves 2 and a stretching cylinder 32. The stretching cylinder 32 is fixedly installed on the left side of the top of the base 1. A sliding frame 33 is fixedly installed inside the stretching cylinder 32. A tension sensor 35 is installed inside the sliding frame 33. The second clamp 5 is fixedly connected to the inside of the tension sensor 35 and is movably clamped inside the guide groove 2.

[0027] By providing a plurality of guide grooves 2 equidistantly arranged on the top of the base 1 and the first clamp 4 and the second clamp 5 that match the guide grooves 2, the stretching cylinder 32 can drive the sliding frame 33 to pull the plurality of second clamps 5 connected to the tension sensor 35 along the guide grooves 2 to stretch the fabric, so as to simultaneously detect the wiring of multiple pieces of fabric and improve the detection efficiency.

[0028] To ensure the stability and accuracy of the detection process, the surface of the base 1 is precisely machined to ensure the parallelism and straightness of the guide grooves 2.

[0029] The tension sensor 35 is installed inside the sliding frame 33 and is used to monitor the change of the force value in real time during the stretching process. The stretching cylinder 32 is selected as a high-performance pneumatic component, which has the characteristics of fast response and stable output to achieve precise stretching of chemical fiber fabrics.

[0030] As Figure 4 and Figure 5 shown, the first clamp 4 and the second clamp 5 are arranged identically. The first clamp 4 includes a lower fixed seat 41. An installation groove 42 is opened inside the lower fixed seat 41. A rotating shaft 43 is rotatably connected inside the installation groove 42. An upper fixed block 44 located inside the installation groove 42 is fixedly connected to the outside of the rotating shaft 43. A worm gear 45 is fixedly installed on the outside of the rotating shaft 43. A worm 46 located outside the worm gear 45 is rotatably connected inside the installation groove 42. A handle 47 is fixedly installed on the top of the worm 46. A rib 48 and a groove 49 are respectively arranged on the inside of the installation groove 42 and the upper fixed block 44.

[0031] The second clamp 5 has the same structure as the first clamp 4, ensuring the interchangeability and consistency of the clamps. When it is necessary to clamp or loosen the workpiece, the operator only needs to rotate the handle 47, and the worm 46 will rotate accordingly. Due to the meshing of the worm 46 and the worm gear 45, the rotating shaft 43 will also rotate accordingly. The rotation of the rotating shaft 43 drives the upper fixed block 44 to move inside the installation groove 42, so as to achieve the purpose of clamping or loosening the workpiece. The cooperation of the rib 48 and the groove 49 ensures the stability of the clamping of the fabric.

[0032] As Figure 3 shown, guide blocks 36 are fixedly connected to the bottoms of the second clamp 5 and the fixed groove 34. The guide blocks 36 are movably sleeved on the outside of the guide rods 31.

[0033] The guide rod 31 is arranged in a rectangular shape, and the guide block 36 is movably clamped inside the guide groove 2.

[0034] The guide rod 31 is finely processed and has good wear resistance and smoothness to reduce the frictional resistance of the guide block 36 during movement. An appropriate gap is provided between the guide block 36 and the guide rod 31 to ensure that the guide block 36 can slide smoothly along the guide rod 31, providing a stable guiding effect for the second fixture 5 and the sliding frame 33.

[0035] As Figure 3 shown, a fixing groove 34 corresponding to the position of the guide groove 2 is formed inside the sliding frame 33, and the tension sensor 35 is fixedly installed inside the fixing groove 34.

[0036] The fixing groove 34 is used to firmly connect the tension sensor 35 to the sliding frame 33 by wiring to ensure that the sensor does not loosen during use. By using multiple tension sensors 35, the tensile strength of multiple pieces of fabric can be detected simultaneously by wiring.

[0037] As Figure 4 shown, the convex strip 48 corresponds to the concave groove 49, and the inner sides of the installation groove 42 and the upper fixing block 44 are coated with an anti-slip rubber layer.

[0038] The contact surface between the upper fixing block 44 and the lower fixing seat 41 is provided with an anti-slip rubber layer to increase the friction force when clamping and fixing the fabric, thereby improving the stability of fixing the fabric.

[0039] As Figure 3 shown, the base 1 includes a frame body 11. A placement groove 12 with a front-side opening is formed inside the frame body 11. A label 13 located above the placement groove 12 is fixedly installed on the front side of the frame body 11, and the placement groove 12 and the label 13 are arranged at equal distances.

[0040] The equally spaced placement grooves 12 cooperate with the label 13 for classification and differentiation, facilitating the placement of items.

[0041] As Figure 1 shown, a controller 6 is fixedly installed at the left front of the top of the base 1.

[0042] The controller 6 adopts a PLC controller, on which a display screen and operation buttons are provided. It can control the stretching cylinder 32 and multiple set tension sensors 35 and receive the tension data detected by the multiple tension sensors 35.

[0043] Next, the working principle of this chemical fiber fabric tensile strength detection device will be specifically described.

[0044] As Figures 1 to 5As shown, the chemical fiber fabric to be detected is set between the first clamp 4 and the second clamp 5 in the open state. The first clamp 4 and the second clamp 5 are exactly the same. By placing the two ends of the fabric on the convex strips 48 on both sides respectively, then turning the handle 47 drives the worm 46 located in the installation groove 42 to rotate. The meshing of the worm 46 and the worm gear 45 can drive the worm gear 45 to rotate. The rotating shaft 43 and the worm gear 45 are coaxially arranged. The rotation of the worm gear 45 synchronously drives the upper fixing block 44 to rotate clockwise along the rotating shaft 43 and approach the convex strip 48. The convex strip 48 is engaged with the groove 49 to improve the clamping tightness of the fabric. By fixing multiple fabrics between multiple groups of the first clamps 4 and the second clamps 5 arranged at equal intervals respectively, then operating the controller 6 to control the stretching cylinder 32 to contract. The stretching cylinder 32 drives the sliding frame 33 located inside it to pull the tension sensor 35 in the fixing groove 34, driving the second clamp 5 to move outward along the guide groove 2 to stretch the fabric connection. The tension sensor 35 is located between the sliding frame 33 and the second clamp 5, automatically detecting the tension magnitude during the stretching of the fabric and can be received and viewed through the controller 6.

[0045] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
