Description

Technical Field

[0001] The utility model relates to the technical field of polyester fabric production detection, in particular to a tensile resistance detection device for polyester fabric production. Background Art

[0002] Polyester fabric is a kind of chemical fiber clothing fabric that is widely used in daily life. Its biggest advantage is its good wrinkle resistance and shape retention. Therefore, it is suitable for outerwear, various bags, tents and other outdoor products. As the production and application of polyester fabrics become more and more extensive, the requirements for it are also getting higher and higher. In order to ensure the production quality of polyester fabrics, after the production of polyester fabrics is completed, random sampling will be carried out on the tensile strength of polyester fabrics to ensure the quality of polyester fabrics.

[0003] In order to improve the problem that manual clamps are required for pulling inspection, accurate tensile strength data cannot be obtained, the detection effect is poor, the tightness of the polyester cloth cannot be adjusted when the clamp is clamped, and safety hazards are easily generated when the polyester cloth is pulled. The utility model patent with application number 202223285050.8 in the public technology is applied, including a workbench, four symmetrical support legs are arranged around the lower end of the workbench, and a support plate is fixedly connected between the support legs. A first fixed frame is arranged on the left side of the top of the workbench, and the first fixed frame A first clamping assembly is arranged inside, a first slide is arranged in the middle of the upper surface of the workbench, a second fixing frame is arranged on the right side of the top of the workbench, a second clamping assembly is arranged inside the second fixing frame, and an adjusting tensioning assembly is arranged on the right side of the workbench. Although the tightness of the polyester cloth can be adjusted and fixed by the cooperation of the first clamping assembly, the second clamping assembly and the adjusting tensioning assembly, and the tensile force data can be accurately obtained, which is practical, there are still certain disadvantages in the actual use process, because the polyester fabric has high strength. The strength of short fibers is 2.6-5.7cN / dtex, and that of high-strength fibers is 5.6-8.0cN / dtex. In the actual tensile performance test of polyester fabrics by enterprises, the polyester fabrics will not be partially pulled apart, but the polyester fabrics will be stretched to the specified maximum force, followed by the removal of the tension of the polyester fabrics, and then the degree of deformation of the polyester fabrics is judged to know the tensile performance of the polyester fabrics. However, in the comparative document, the polyester fabric is tensilely resisted by moving the clamping plates on both sides by driving the threaded column with a motor. When the force on the polyester fabric is greater than the maximum force required for the specified stretching during the pulling of the polyester fabric, the pulling operation of the polyester fabric cannot be stopped in time, and the working load of the motor will increase rapidly at this time, which is not conducive to the long-term and stable use of the detection device. In addition, when the clamped and stretched polyester fabric continues to be subjected to increasing force, it will collapse wildly at the moment of breaking, affecting safety. Utility Model Content

[0004] The purpose of the utility model is to provide a tensile resistance detection device for polyester fabric production, so as to solve the problem proposed in the above-mentioned background technology that the polyester fabric is subjected to tensile resistance by driving the threaded column by a motor to drive the movement of the clamping plates on both sides. During the pulling of the polyester fabric, when the force on the polyester fabric is greater than the maximum force required for the specified stretching, the pulling operation of the polyester fabric cannot be stopped in time, and the working load of the motor will increase rapidly at this time, which is not conducive to the long-term stable use of the detection device. In addition, after the clamped and stretched polyester fabric continues to be subjected to increased force, it will collapse arbitrarily at the moment of breaking, affecting safety.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tensile strength testing device for polyester fabric production, comprising a workbench, legs are fixedly connected to the four corners of the lower surface of the workbench, a support plate is fixedly connected between the legs, a motor is fixedly connected to the surface of one side of the workbench, a first screw rod is connected to the inside of the workbench for horizontal rotation, the first screw rod is fixedly connected to the output shaft of the motor, square frames are provided on both sides of the upper surface of the workbench, a bottom plate is fixedly connected to the lower surface of the square frame, the bottom plate is connected to the first screw rod through a transmission assembly, a hydraulic cylinder is fixedly connected to the center of the upper surface of the square frame, a pressure plate is fixedly connected to the bottom end of the hydraulic cylinder, the lower surface of the pressure plate is pressed against the fabric, the lower surface of the fabric is pressed against the anti-skid pad, the anti-skid pad is fixedly connected to the contact surface of the square frame, the front and rear sides of the upper surface of the workbench The cam is connected to the second end of the second guide rail, and the cam is connected to the first end of the second guide rail by a threaded connection.

[0006] Preferably, two balls are fixedly connected to the four corners of the lower surface of the base plate, and the balls are in contact with the upper surface of the workbench.

[0007] Preferably, material boxes are placed on both sides of the upper surface of the pallet.

[0008] Preferably, reference components are provided on the front and rear sides of the vertical plates, and the reference components include support rods, transverse grooves, pointers and scales. The plurality of support rods are respectively fixedly connected to the front and rear sides of the plurality of vertical plates, and a portion of the support rods passes through the square frame through the transverse grooves. Pointers are fixedly connected to the upper and lower ends of the outer walls of the support rods, and a scale is provided on the rear side of the pointer, and the scale is arranged above the surface of the square frame.

[0009] Compared with the prior art, the beneficial effects of the utility model are: the tensile strength detection device for polyester fabric production has the following advantages over the traditional technology:

[0010] Through the cooperation among the workbench, transmission assembly, legs, motor, first screw rod, frame, support plate, hydraulic cylinder, pressure plate, fabric, anti-skid pad, U-shaped rod and slide, the pressure plate presses the fabric and then starts the motor to rotate the first screw rod. The first screw rod will perform thread transmission on the thread block, so that the two frames can move toward each other and stretch the clamped fabric. When the tensile force on the fabric increases, the force at the contact point between the first screw rod and the thread of the thread block continues to increase. As the force continues to increase, the compression degree of the compression spring increases, which can cause a gap between the thread block and the first screw rod. At this time, the first screw rod no longer performs thread transmission on the thread block, and the tensile force on the fabric is stopped. The motor is not easy to be in a high-load state, which is conducive to the long-term and stable use of the detection device. In addition, the fabric is not easy to break, so as to avoid its breakage and arbitrary collapse to injure the operator.

[0011] Through the cooperation between the workbench, transmission assembly, reference assembly, support legs, motor, first screw rod, frame, support plate, hydraulic cylinder, pressure plate, fabric, anti-slip pad, U-shaped rod and slide, the operator can apply force to the knob to adjust the pressing force between the thread block and the outer wall of the first screw rod. During this process, the support rod and the pointer will move with the vertical plate. During this process, the operator can more intuitively know the pressing force between the thread block and the outer wall of the first screw rod by observing the relationship between the pointer and the scale, and then it is convenient to know the force value when the first screw rod is separated from the thread block, so as to determine the maximum pulling force applied by the two frames to the fabric.
