Description

Technical Field

[0001] This utility model relates to the field of testing devices, and in particular to a tensile testing device for textile coated fabrics. Background Technology

[0002] Imitation cashmere is characterized by its smoothness, softness, and elasticity, and offers more vibrant and richer colors than natural cashmere. It is made from acrylic fibers that undergo a special process to give them the smooth, soft, and elastic feel of natural cashmere, while also possessing the excellent dyeing properties of acrylic. Currently, the production process of imitation cashmere fabrics requires the use of tensile testing equipment to test the fabric's tensile strength and determine its quality. However, existing testing equipment directly uses a threaded rod to move a clamping plate to hold and fix the fabric before starting the tensile test. This method is convenient for applications with low tensile strength requirements, but when the tensile strength requirement is too high, this method of fixing the fabric becomes unstable during use, causing the fabric to slip against the clamping plate during stretching, affecting the tensile strength test results.

[0003] In existing technologies, such as the Chinese patent announcement CN220729831U entitled "A Tensile Strength Testing Device for Imitation Cashmere Fabric," a base and a support rod fixed at the center of its top are included. The device also includes a U-shaped support frame fixed to the top of the base, with a hydraulic rod for providing power to other parts fixed to the top of the inner cavity of the support frame. This invention, through the cooperation of a positioning shell, a positioning plate, and a positioning mechanism, can fix the fabric, preventing positional movement during testing. A secondary fixing mechanism is then used to further fix the fabric, effectively improving the fixing effect and testing accuracy. Simultaneously, with the cooperation of the moving mechanism and the display mechanism, the degree of fabric deformation can be accurately determined, making the device more applicable and solving the problems of poor fabric fixing and inability to determine the degree of fabric deformation in current devices.

[0004] In existing technologies, fabric tensile testing suffers from poor accuracy when tensile strength is not referenced because fabric elongation is directly proportional to tensile force.

[0005] Therefore, it is necessary to provide a tensile testing device for textile coated fabrics to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a tensile testing device for textile coated fabrics, which solves the problem of poor accuracy in tensile testing of fabrics when tensile strength is not referenced because the fabric elongation is directly proportional to the tensile force.

[0008] Preferably, the force gauge is located directly above the lifting plate and is fixedly connected to the bottom of the cylinder.

[0009] Preferably, the limiting posts and the support platform are perpendicular to each other, and the number of limiting posts is four.

[0010] Preferably, the extrusion plate and the baffle are parallel to each other, and the extrusion plate and the threaded column are perpendicular to each other.

[0014] Preferably, the moving mechanism includes a support column, which is fixedly connected to the bottom of the support platform, and a sliding wheel is installed at the bottom of the support column.

[0015] Compared with related technologies, the tensile strength testing device for coated textile fabrics provided by this utility model has the following advantages:

[0016] This utility model provides a tensile testing device for textile coated fabrics. By setting up a tensile gauge, when conducting a fabric tensile test, the fabric is fixed at the top of the support platform and the bottom of the lifting plate. At this time, the cylinder is activated, allowing the cylinder to stretch the fabric through the lifting plate, thereby enabling the tensile gauge to detect the tension of the cylinder, that is, to detect the tensile strength of the fabric. This allows the operator to mark the tensile strength and elongation of the fabric through the tensile gauge and the scale groove, thereby improving the diversity of the fabric tensile test data, that is, improving the accuracy of the fabric tensile test results.

[0017] By setting up an extrusion plate, when the fabric is being stretched and fixed, one end of the fabric is placed on the top of the support platform. At this time, the threaded column is rotated, which causes the extrusion plate to tightly press against the front of the fabric, thereby clamping and fixing the fabric to the top of the support platform, thus achieving the effect of fixing the fabric.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1A schematic diagram of a preferred embodiment of a tensile testing device for coated textile fabrics provided by this utility model; Figure 2 for Figure 1 The image shows a front view of a tensile testing device for coated textile fabrics. Figure 3 for Figure 1 The image shows a front view of the extrusion plate in a tensile testing device for coated textile fabrics. Figure 4 for Figure 1 The image shows a front view of a tensile tester in a textile coated fabric tensile testing device. The device includes a support platform 1, a baffle 2 fixedly connected to the top of the support platform 1, a limiting post 3 fixedly connected to the top of the support platform 1, a top plate 4 fixedly connected to the top of the limiting post 3, a back plate 5 fixedly connected to the top of the support platform 1, a scale groove 6 on the front of the back plate 5, a lifting plate 7 movably sleeved on the outside of the limiting post 3, a tensile tester 8 fixedly connected to the top of the lifting plate 7, a cylinder 9 fixedly installed at the bottom of the top plate 4, a positioning block 10 fixedly connected to the top of the support platform 1, a threaded post 11 threaded inside the positioning block 10, a compression plate 12 movably sleeved at one end of the threaded post 11, a limiting mechanism 13 on the top of the support platform 1, a toothed plate 14 fixedly connected to the front of the baffle 2, a sliding ball 15 movably sleeved on the side of the limiting post 3, and a moving mechanism 16 at the bottom of the support platform 1.

[0025] The tensile gauge 8 is located directly above the lifting plate 7 and is fixedly connected to the bottom of the cylinder 9. By setting the tensile gauge 8, when the fabric tensile test is performed, the fabric is fixed on the top of the support platform 1 and the bottom of the lifting plate 7. At this time, the cylinder 9 is activated, so that the cylinder 9 can stretch the fabric through the lifting plate 7, thereby allowing the tensile gauge 8 to detect the tensile force of the cylinder 9, that is, to detect the tensile force of the fabric. This allows the staff to mark the tensile force and elongation of the fabric through the tensile gauge 8 and the scale groove 6, thereby improving the diversity of the tensile test data of the fabric and thus improving the accuracy of the tensile test results of the fabric.

[0026] The limiting posts 3 are perpendicular to each other and there are four limiting posts 3. By setting the limiting posts 3, when the lifting plate 7 stretches the fabric, the limiting posts 3 can limit the lifting plate 7 that moves up and down, so as to avoid the problem of uneven fabric tension caused by the tilting of the lifting plate 7 when it rises and falls, thereby improving the stability of the lifting plate 7 when it moves up and down.

[0027] The extrusion plate 12 and the baffle 2 are parallel to each other, and the extrusion plate 12 and the threaded column 11 are perpendicular to each other. By setting the extrusion plate 12, when the fabric is fixed and stretched, one end of the fabric is placed on the top of the support platform 1. At this time, the threaded column 11 is rotated, so that the threaded column 11 drives the extrusion plate 12 to tightly press on the front side of the fabric, thereby clamping and fixing the fabric on the top of the support platform 1, thus achieving the effect of fixing the fabric.

[0028] The limiting mechanism 13 includes a limiting sleeve 131, which is fixedly connected to the top of the support platform 1. A limiting rod 132 is movably sleeved inside the limiting sleeve 131, and one end of the limiting rod 132 is fixedly connected to the front of the extrusion plate 12. By setting the limiting mechanism 13, when the fabric is clamped and fixed, the limiting rod 132 can limit the extrusion plate 12 during reciprocating movement through the limiting sleeve 131, thereby avoiding the problem of incomplete fabric clamping caused by the extrusion plate 12 tilting and shifting during movement, thus improving the stability of fabric clamping and fixing.

[0029] The toothed plate 14 is the same size as the extrusion plate 12, and the toothed plate 14 and the extrusion plate 12 are parallel to each other. By setting the toothed plate 14, when the fabric is clamped and fixed, the toothed plate 14 can greatly improve the friction between the fabric and the baffle 2, so as to avoid the problem of the fabric falling off when stretched when the fabric surface is relatively smooth, thereby improving the tightness of the fabric when it is fixed.

[0030] The number of sliding balls 15 is several, and the sliding balls 15 are evenly distributed on the side of the limiting post 3. By setting the sliding balls 15, when the lifting plate 7 stretches the fabric, the sliding balls 15 can limit the up and down movement of the lifting plate 7, thereby avoiding the problem of friction between the lifting plate 7 and the limiting post 3 when the lifting plate 7 moves up and down for a long time, thus improving the smoothness of the up and down movement of the lifting plate 7.

[0031] The moving mechanism 16 includes a support column 161, which is fixedly connected to the bottom of the support platform 1. A sliding wheel 162 is installed at the bottom of the support column 161. By setting up the moving mechanism 16, when the testing device is moved and transported, the support platform 1 is pushed, so that the sliding wheel 162 can drive the support platform 1 to move horizontally through the support column 161, thereby achieving the effect of moving and transporting the tensile testing device, which brings convenience to the adjustment of the working position of the fabric tensile testing device.

[0032] The working principle of the tensile strength testing device for coated textile fabrics provided by this utility model is as follows:

[0033] Step 1: First, during the fabric tensile test, the fabric is fixed to the top of the support platform 1 and the bottom of the lifting plate 7. Then, cylinder 9 is activated, allowing it to stretch the fabric via the lifting plate 7. This enables the tension gauge 8 to measure the tension of cylinder 9, thus measuring the fabric's tensile strength. The operator can then mark the fabric's tensile strength and elongation using the tension gauge 8 and the scale groove 6, thereby increasing the diversity of the fabric's tensile strength test data and improving the accuracy of the test results. When the lifting plate 7 stretches the fabric, the limiting post 3 limits the vertical movement of the lifting plate 7, preventing tilting during its ascent and descent. The problem of uneven fabric tension is solved, thereby improving the stability of the lifting plate 7 when it moves up and down. When the fabric is fixed and stretched, one end of the fabric is placed on the top of the support platform 1. At this time, the threaded column 11 is rotated, so that the threaded column 11 drives the extrusion plate 12 to tightly press against the front of the fabric, thereby clamping and fixing the fabric on the top of the support platform 1, thus achieving the fabric fixing effect. When the fabric is clamped and fixed, the limiting rod 132 can limit the extrusion plate 12 when it moves back and forth through the limiting sleeve 131, so as to avoid the problem of the extrusion plate 12 tilting and shifting when it moves, resulting in incomplete fabric clamping, thereby improving the stability of the fabric clamping and fixing.

[0034] Step 2: When the fabric is clamped and fixed, the toothed plate 14 greatly increases the friction between the fabric and the baffle 2, which avoids the problem of the fabric falling off when stretched due to its relatively smooth surface, thus improving the tightness of the fabric fixation. When the lifting plate 7 stretches the fabric, the sliding ball 15 limits the vertical movement of the lifting plate 7, which avoids the problem of friction between the lifting plate 7 and the limiting column 3 during long-term lifting and lowering, thus improving the smoothness of the vertical movement of the lifting plate 7. When the testing device is moved and transported, the support platform 1 is pushed, so that the sliding wheel 162 can drive the support platform 1 to move horizontally through the support column 161, thereby achieving the effect of moving and transporting the tensile testing device, which brings convenience to the adjustment of the working position of the fabric tensile testing device.

[0035] Compared with related technologies, the tensile strength testing device for coated textile fabrics provided by this utility model has the following advantages:

[0036] By setting up a tensile gauge 8, when conducting fabric tensile testing, the fabric is fixed at the top of the support platform 1 and the bottom of the lifting plate 7. At this time, the cylinder 9 is activated, allowing the cylinder 9 to stretch the fabric through the lifting plate 7. This enables the tensile gauge 8 to detect the tension of the cylinder 9, i.e., to detect the tensile strength of the fabric. This allows the operator to mark the tensile strength and elongation of the fabric using the tensile gauge 8 and the scale groove 6, thereby improving the diversity of the fabric tensile test data and thus improving the accuracy of the fabric tensile test results.
