Description

Technical Field

[0001] The invention relates to the technical field of stretch testing devices, and in particular to an automatic elasticity detection device for textiles. Background Art

[0002] After textile fabrics are processed by fabric equipment, they need to be subjected to various performance tests, including flame retardancy, tensile properties, etc. For the elasticity test of textiles, the more conventional test method is to apply a certain tensile force to the fabric and then test its tensile length.

[0003] Conventional testing is to cut off a portion of the fabric and then place it on a tensile testing machine for testing. However, when the fabric is processed and manufactured, it is usually processed and produced continuously, and then the fabric is wound on a roller. Therefore, the fabric is continuous and very long. In some cases where there are certain requirements for the elasticity of the fabric, it is necessary to make certain adjustments to the structure of the fabric, that is, design more curls in the fabric, or increase the thickness of the fabric. In fact, it is difficult to ensure that the fabric produced in this way has very uniform elasticity everywhere. And because the fabric is integrated, if a certain length of fabric is cut off at intervals during the processing process for elasticity testing, it will not only destroy the continuous structure of the fabric, but the operation process will also be very cumbersome. Therefore, a device that can test the elasticity of the fabric in real time during the production process can be designed. Summary of the invention

[0004] The object of the present invention is to provide an automatic testing device for elasticity of textiles, which can efficiently and automatically perform tensile testing on fabrics during their production process.

[0005] The present invention is implemented through the following technical scheme: The automatic elasticity detection device of the textile of the present invention includes a bottom plate, a first support seat, a second support seat and a third support seat arranged on the bottom plate in sequence along the horizontal direction, a first gap arranged between the first support seat and the second support seat, a second gap arranged between the second support seat and the third support seat, a first transmission roller arranged above the first support seat, a second transmission roller arranged above the second support seat, a third transmission roller arranged above the third support seat, and a stretching device arranged below the inside of the second gap; the woven cloth passes through the first support seat, the first gap, the second support seat, the second gap, and the third support seat in sequence; the first transmission roller, the second transmission roller and the third transmission roller are all arranged on the upper surface of the woven cloth.

[0006] Further, the stretching device includes a pressure roller horizontally arranged in the first gap, a pair of first supporting devices respectively arranged at both ends of the pressure roller, and a height detection device arranged on the bottom plate; the first supporting device includes a first telescopic cylinder vertically arranged on the bottom plate, a first supporting plate arranged at the end of the pressure roller, and a pressure detection device arranged on the lower side of the first supporting plate; the telescopic rod of the first telescopic cylinder abuts against the pressure detection device; the height detection device is arranged directly below the first supporting plate and facing the first supporting plate; the pressure roller is arranged on the upper side of the woven cloth.

[0007] Furthermore, the first supporting device also includes a first sliding rod vertically arranged on the bottom plate; a first sliding hole is arranged at the end of the first supporting plate; and the first sliding rod is slidably arranged in the first sliding hole.

[0008] Furthermore, the height detection device is a laser rangefinder.

[0009] Furthermore, the pressing roller is a hollow structure, and a through hole is opened on the upper side of the pressing roller.

[0010] Furthermore, a pressing device is provided above the second gap, and the pressing device is used to press the woven fabric.

[0011] Furthermore, the pressing device includes a pressing block disposed above the second gap, and a pair of second supporting devices respectively disposed at two ends of the pressing block; the second supporting devices are used to drive the pressing block to rise and fall.

[0012] Furthermore, the second supporting device includes a fixed plate connected to the outer wall of the second supporting seat and the third supporting seat, a second telescopic cylinder arranged on the fixed plate, a second supporting plate arranged at the end of the pressing block, a second sliding rod vertically arranged on the fixed plate, and a second sliding hole opened on the second supporting plate; the telescopic rod of the second telescopic cylinder is connected to the second supporting plate, and the second sliding rod is slidably arranged in the second sliding hole.

[0013] Furthermore, an upper edge of the second support seat close to the third support seat is arc-shaped, and an upper edge of the third support seat close to the second support seat is arc-shaped; both sides of the lower end of the pressing block are concave arcs.

[0014] The technical solution of the present invention has at least the following advantages and beneficial effects: the automatic elasticity detection device for textiles of the present invention, when in use, the woven fabric produced passes through the first support seat, the second support seat, and the third support seat in sequence before being rolled up. During the rolling process, the woven fabric can be subjected to a tensile elasticity test at intervals of a certain length to verify the uniformity of the woven fabric performance and ensure the quality of the woven fabric. When performing the tensile test, the third transmission roller and the second transmission roller stop rotating (and stop rolling at the same time), and the first transmission roller continues to rotate. At this time, the woven fabric that continues to enter will enter the first gap for temporary storage. Since the woven fabric in the second gap remains motionless under the restriction of the second transmission roller and the third transmission roller, the woven fabric in the second gap can be subjected to a tensile test by the tensile device. At this time, the tensile test performed only tests whether the woven fabric meets the elasticity under the use conditions, and does not test the ultimate elasticity of the woven fabric. After the test, the second transmission roller and the third transmission roller start to rotate synchronously to continue to roll up the woven fabric. In this way, it is possible to test whether the fabric at each certain length on the fabric meets the elastic requirements of the use environment without damaging the fabric, which can better guarantee the performance of the fabric. During the test, there is no need to remove the fabric or stop production, and the testing process is more efficient and automated. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example

[0026] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 3As shown, the automatic elasticity detection device for textiles of this embodiment includes a base plate 10, a first support seat 11, a second support seat 12 and a third support seat 13 arranged on the base plate 10 in sequence along the horizontal direction, a first gap 14 arranged between the first support seat 11 and the second support seat 12, a second gap 15 arranged between the second support seat 12 and the third support seat 13, a first transmission roller 16 arranged above the first support seat 11, a second transmission roller 17 arranged above the second support seat 12, a third transmission roller 18 arranged above the third support seat 13, and a stretching device 20 arranged below the inside of the second gap 15; the woven fabric 40 passes through the first support seat 11, the first gap 14, the second support seat 12, the second gap 15, and the third support seat 13 in sequence; the first transmission roller 16, the second transmission roller 17 and the third transmission roller 18 are all arranged on the upper surface of the woven fabric 40. Specifically, the woven fabric 40 produced during use is wound up after passing through the first support seat 11, the second support seat 12, and the third support seat 13 in sequence. During the winding process, the woven fabric 40 can be subjected to a tensile elasticity test at intervals of a certain length to verify the uniformity of the performance of the woven fabric 40 and ensure the quality of the woven fabric 40. When conducting the tensile test, the third transmission roller 18 and the second transmission roller 17 stop rotating (and stop winding at the same time), and the first transmission roller 16 continues to rotate. At this time, the woven fabric 40 that continues to enter will enter the first gap 14 for temporary storage. Since the woven fabric 40 in the second gap 15 remains motionless under the restriction of the second transmission roller 17 and the third transmission roller 18, the woven fabric 40 in the second gap 15 can be subjected to a tensile test by the tensile device 20. At this time, the tensile test only tests whether the woven fabric 40 meets the elasticity under the use conditions, and does not test the ultimate elasticity of the woven fabric 40. After the test is finished, the second transmission roller 17 and the third transmission roller 18 start to rotate synchronously (the first transmission roller 16, the second transmission roller 17, and the third transmission roller 18 are all driven by independent motors) to continue to reel up the fabric 40. In this way, it is possible to test whether each certain length of fabric on the fabric 40 meets the elasticity requirements of the use environment without damaging the fabric 40, which can better ensure the performance of the fabric 40. In addition, the fabric 40 does not need to be removed during the test, and the production does not need to be stopped. The test process is more efficient and automated.

[0027] The stretching device 20 in this embodiment includes a pressure roller 21 horizontally arranged in the first gap 14, a pair of first supporting devices respectively arranged at both ends of the pressure roller 21, and a height detection device 25 arranged on the bottom plate 10; the first supporting device includes a first telescopic cylinder 23 vertically arranged on the bottom plate 10, a first supporting plate 22 arranged at the end of the pressure roller 21, and a pressure detection device 27 arranged on the lower side of the first supporting plate 22; the telescopic rod of the first telescopic cylinder 23 abuts against the pressure detection device 27; the height detection device 25 is arranged directly below the first supporting plate 22 and is arranged toward the first supporting plate 22; the pressure roller 21 is arranged on the upper side of the woven cloth 40. Specifically, when performing the tensile test, the first telescopic cylinder 23 first drives the pressure roller 21 to slowly descend. When the value of the pressure detection device 27 changes, the first data of the height detection device 25 is recorded, and then the pressure roller 21 continues to descend. When the vertical value of the pressure detection device 27 no longer changes (or becomes 0), it is considered that the weight of the pressure roller 21 has been completely pressed on the fabric 40, and the second data of the height detection device 25 is recorded. Through the first data of the height detection device 25, the specific length of the fabric 40 participating in the tensile test in the second gap 15 can be obtained (converted by the high end of the second support seat 12 and the third support seat 13, the length of the arc surface of the pressure roller 21, etc.), and the difference between the first data and the second data can be obtained. The length of the fabric 40 stretched can be obtained, and thus the deformation of the fabric 40 under a given tension can be obtained. In this way, the length of the fabric 40 and the length of the pulled rope are measured each time, and more accurate values ​​can be obtained. It should be noted that a sleeve 26 with an open lower end can be provided under the first support plate 22, and then a pressure detection device 27 can be placed on the top of the sleeve 26, and then the telescopic rod of the first telescopic cylinder 23 can be inserted into the sleeve 26, so that the pressure roller 21 is not prone to unknown. The pressure detection device 27 can use a conventional pressure sensor.

[0028] The first support device in this embodiment also includes a first slide bar 24 vertically arranged on the bottom plate 10; a first slide hole is arranged at the end of the first support plate 22; and the first slide bar 24 is slidably arranged in the first slide hole. Specifically, the first slide bar 24 can better keep the pressure roller 21 in vertical motion.

[0029] The height detection device 25 in this embodiment is a laser rangefinder.

[0030] The pressing roller 21 in this embodiment is a hollow structure, and a through hole is opened on the upper side of the pressing roller 21. Specifically, by injecting liquids of different weights into the pressing roller 21, the woven fabric 40 can be stretched under different weights without replacing the pressing roller 21 of different weights.

[0031] In this embodiment, a pressing device 30 is disposed above the second gap 15 , and the pressing device 30 is used to press the woven fabric 40 .

[0032] The pressing device 30 in this embodiment includes a pressing block 31 disposed above the second gap 15, and a pair of second supporting devices disposed at both ends of the pressing block 31; the second supporting devices are used to drive the pressing block 31 to rise and fall. Specifically, when no test is performed, the second supporting device pushes the pressing block 31 above the fabric 40, and when a tensile test is performed, the second supporting device pulls the pressing block 31 downward so that the pressing block 31 is pressed on the fabric 40, so as to better perform the tensile test and avoid sliding.

[0033] The second support device in this embodiment includes a fixed plate 34 connected to the outer walls of the second support seat 12 and the third support seat 13, a second telescopic cylinder 33 arranged on the fixed plate 34, a second support plate 32 arranged at the end of the pressing block 31, a second slide rod 35 vertically arranged on the fixed plate 34, and a second slide hole opened on the second support plate 32; the telescopic rod of the second telescopic cylinder 33 is connected to the second support plate 32, and the second slide rod 35 is slidably arranged in the second slide hole. Specifically, the second support device mainly drives the pressing block 31 to move up and down through the second telescopic cylinder 33. It should be noted that both the first telescopic cylinder 23 and the second telescopic cylinder 33 can use screw-type electric push rods, hydraulic cylinders, cylinders, etc.

[0034] In this embodiment, the upper edge of the second support seat 12 near the third support seat 13 is arc-shaped, and the upper edge of the third support seat 13 near the second support seat 12 is arc-shaped; both sides of the lower end of the pressing block 31 are concave arcs. Specifically, this can not only better protect the fabric 40, but also increase the contact area between the pressing block 31 and the fabric 40, and improve the fixing effect of the pressing block 31 on the fabric 40.

[0035] In summary, the textile elasticity automatic detection device of this embodiment, when in use, the woven fabric 40 produced passes through the first support seat 11, the second support seat 12, and the third support seat 13 in sequence before being rolled up. During the rolling process, the woven fabric 40 can be subjected to a tensile elasticity test at intervals of a certain length to verify the uniformity of the performance of the woven fabric 40 and ensure the quality of the woven fabric 40. When performing the tensile test, the third transmission roller 18 and the second transmission roller 17 stop rotating (and stop rolling up at the same time), and the first transmission roller 16 continues to rotate. At this time, the woven fabric 40 that continues to enter will enter the first gap 14 for temporary storage. Since the woven fabric 40 in the second gap 15 remains motionless under the restriction of the second transmission roller 17 and the third transmission roller 18, the woven fabric 40 located in the second gap 15 can be subjected to a tensile test by the stretching device 20. At this time, the tensile test performed only tests whether the woven fabric 40 meets the elasticity under the use conditions, and does not test the ultimate elasticity of the woven fabric 40. After the test, the second transmission roller 17 and the third transmission roller 18 start to rotate synchronously to continue to roll up the woven fabric 40. In this way, it is possible to test whether the fabric at each interval of a certain length on the fabric 40 meets the elastic requirements of the use environment without damaging the fabric 40, thereby better ensuring the performance of the fabric 40. During the test, there is no need to remove the fabric 40 or stop production, and the testing process is more efficient and automated.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
