Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of fabric tension detection, and in particular, to a sewing fabric tension detection device. Background Art

[0002] Sewing fabrics refer to fabrics specifically designed for sewing machine processing. They must withstand needle penetration and yarn friction without damage, and resist deformation or distortion during the sewing process. They must also be compatible with sewing thread and other materials. Common sewing fabrics include woven fabrics (denim, shirting), knitted fabrics (T-shirts, ribbing), and specialty fabrics (waterproof coated fabrics, stretch spandex fabrics). They generally exhibit good sewability, stability, and compatibility.

[0003] Testing the tension of sewing fabrics is a key step in ensuring the quality of sewing and finished garments. When testing the tension of sewing fabrics, first use a cutting knife to cut several strips of the same size from the fabric. Then clamp the upper and lower ends of the strips on the working end of the testing device, and then set the stretching speed until the sewing fabric is broken. At this time, record the breaking strength and elongation. These parameters can indirectly reflect the fabric's tension tolerance.

[0004] In the prior art, when testing sewing fabrics, it is necessary to use tools such as cutters to cut the sewing fabrics into samples of equal size. However, due to the limitations of the tools, first of all, ordinary cutters or templates are difficult to provide stable and constant pressure. When cutting some thicker, thinner or elastic sewing fabrics, it is easy for the size to deviate from the set value due to knife slippage or fabric deformation, which not only affects the size of the sample, but also affects the flatness of the sample edge. That is to say, during the test process, the strength value measured for a sample with a smaller size may be inflated, and a sample with an uneven edge is prone to premature breakage during the test, resulting in a significant gap in the test results between each sample, thereby causing deviations in the test results and affecting the judgment of the fabric tension.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] like Figures 1 to 6As shown, it shows a sewing fabric tension detection device in one embodiment of the present invention, a sewing fabric tension detection device, including a device frame 1, a tension detector 2 is installed on the device frame 1, a control device body 3 is installed on the tension detector 2, and also includes a clamping seat 4, a clamping assembly and a sample cutting assembly. There are two clamping seats 4, one clamping seat 4 is fixedly installed on the moving end of the tension detector 2 through a tension sensor 5, and the other clamping seat 4 is fixedly installed on the working base of the tension detector 2. The two clamping seats 4 are in the same straight line, and the two clamping seats 4 are both equipped with a clamping assembly for clamping the sewing fabric sample. The clamping assembly includes a positioning frame 6, a sliding The clamping jaws 7, springs 8, limit closing parts and clamping parts, the front and rear sides of the two clamping seats 4 are fixedly installed with positioning frames 6, the two positioning frames 6 on each clamping seat 4 are symmetrically arranged, and a sliding clamping jaw 7 is slidably installed inside each positioning frame 6, the two sliding clamping jaws 7 in each clamping seat 4 are symmetrically arranged, and a spring 8 is fixedly installed between each sliding clamping jaw 7 and the positioning frame 6, and the left and right sides of each clamping seat 4 are fixedly installed with a limit closing part, and the two limit closing parts on each clamping seat 4 are symmetrically arranged, which are used to control the synchronous action of the two sliding clamping jaws 7 in the corresponding clamping seat 4, and a clamping part is installed on the end of each sliding clamping jaw 7 that contacts the sewing fabric sample for clamping the sewing fabric sample.

[0025] Specifically, when testing the tension of a sewing fabric, first place the sewing fabric into the sample cutting assembly, cut a piece of sewing fabric into several sewing fabric samples of the same size (hereinafter referred to as the sewing fabric sample), then move one of the samples into the position of the tension tester 2, place the two ends of the sample between the two clamping seats 4, and then start the limit closing part in the clamping groove, thereby simultaneously pushing the two sliding jaws 7 to move in the positioning frame 6 until the sliding jaw 7 drives the clamping part to move until the clamping part contacts the sample and fixes the sample, then the limit closing part can be closed and locked. At this time, the surface of the sample is flat and there is no wrinkle. At this time, the sample can be tested, and the tension tester 2 is turned on by the control device body 3. The sample is subjected to tension through the movement of the moving end of the tension tester 2, and the stretching speed is set. During the detection process, the tension sensor 5 is set, the tension sensor 5 is provided with a signal transmitter, and the control device body 3 is provided with a matching signal transmitter. The receiver, after the tension sensor 5 detects the corresponding data, will send it to the signal receiver through the signal transmitter. At this time, the control device body 3 can analyze the tension exerted on the sample through this data, and perform real-time detection on this data, and convert the tension data into electrical signals. After processing, these electrical signals can be converted into digital or analog signals and recorded for subsequent analysis. By analyzing the tension data, the tension that the sewing fabric can withstand is determined until the sample is broken, and then the limit closing part is released. At this time, the spring 8 is subjected to tension, and the sliding clamp 7 is sent to the inside of the positioning frame 6, thereby releasing the sample. After the broken sample is removed, the next sample is clamped, and the above operation steps are repeated to test multiple samples. The breaking strength and deformation rate data of multiple samples cut from the same sewing fabric indirectly reflect the tension of the sewing fabric, thereby optimizing the processing quality, improving the sewing efficiency and the quality of the stitches during sewing through the tension data of the sewing fabric.

[0026] The above, such as Figures 2 to 4 As shown, the limiting closing part includes a clamping block 9 and a first driving member 11. A clamping block 9 is slidably installed on the left and right sides of each clamping seat 4. The two clamping blocks 9 on each clamping seat 4 are symmetrically arranged. A V-shaped groove is provided on each clamping block 9, wherein both sides of each sliding clamping jaw 7 are set as inclined surfaces, and the inclined surfaces of the sliding clamping jaw 7 slide with one side of the V-shaped groove. Two first driving members 11 are symmetrically and fixedly installed on each clamping seat 4. The first driving member 11 preferably adopts the form of an electric cylinder. The output end of the first driving member 11 is fixedly connected to the clamping block 9, and also includes a limiting slide 12 and a slide groove 13. Several limiting slides 12 are fixedly installed on each V-shaped groove at equal distances. Several slide grooves 13 are evenly provided on the inclined surfaces on both sides of each sliding clamping jaw 7, and several slide grooves 13 are slidably connected to several limiting slides 12.

[0027] Specifically, when clamping the sample, first place one end of the sample between the two sliding jaws 7, and then synchronously start the two first driving members 11. The two first driving members 11 simultaneously drive the two clamping blocks 9 to move until they pass through the V-groove setting of the clamping block 9. With the cooperation of the inclined surface of the sliding jaw 7, the two sliding jaws 7 are pushed to move at the same time, thereby clamping the sample. In the process of testing the tension of the sample, the sliding jaw 7 is subjected to tension at this time. Through the cooperation of the limiting slide bar 12 and the slide groove 13, under the action of the clamping block 9, the stability of the sliding jaw 7 is improved when it is subjected to tension perpendicular to the moving direction, thereby improving the accuracy of the test. After the test, when it is necessary to take out the broken sample, the first driving member 11 is retracted to make the clamping block 9 move. Under the action of the spring 8, the sliding jaw 7 can be moved back to its original position, and then the broken sample can be taken out.

[0028] The above, such as Figure 3 As shown, the clamping portion includes a clamping plate 14, and each sliding clamping jaw 7 is fixedly mounted with a clamping plate 14. The protruding end of each clamping plate 14 is provided with an arc, and a plurality of strip grooves are evenly spaced on the side of each clamping plate 14 that contacts the sewing fabric sample.

[0029] Specifically, the sample is clamped by setting the clamping plate 14, which is in close contact with the end of the sample. The clamping plate 14 is made of a material with a certain degree of flexibility, and the curvature of the protruding end of the clamping plate 14 is set. When clamping the sample, stress concentration at the clamping position of the sample can be avoided, thereby making the detection more accurate.

[0030] like Figure 5 、 Figure 6As shown, the sample cutting assembly is installed on the device frame 1, and is used to cut out a number of sewing fabric patterns of the same specification from the same piece of sewing fabric. The sample cutting assembly includes a cutting frame 15, a feeding frame 16, a second driving member 18 and a cutting portion. The cutting frame 15 is fixedly mounted on the device frame 1, and the feeding frame 16 is fixedly mounted on the cutting frame 15. A covering frame 17 is provided on the feeding frame 16. The covering frame 17 is slidably matched with the cutting frame 15, and the feeding frame 16 is adapted to the covering frame 17. The feeding frame 16 and the covering frame 1 7 is also provided with a number of through slots 19 arranged at equal distances, and the several through slots 19 on the feeding rack 16 correspond one to one with and dock with the several through slots 19 on the covering rack 17. The feeding rack 16 is provided with a feeding area and a transition area on both sides of the feeding area. The transition area is higher than the feeding area. The second driving member 18 is fixedly mounted on the cutting rack 15. The second driving member 18 is preferably in the form of an electric cylinder. The output end of the second driving member 18 is fixedly connected to the covering rack 17. The cutting portion is installed inside the cutting rack 15 for cutting the sewing fabric sample.

[0031] Specifically, when cutting the sample, the sewing fabric (set to a rectangular shape) is placed in the loading area on the loading rack 16, and then the second driving member 18 is started. The second driving member 18 pushes the covering rack 17 to move until the covering rack 17 moves above the loading rack 16, and the covering rack 17 and the loading rack 16 form a whole, thereby fixing the sewing fabric. At this time, the cutting part is started. Through the setting of the cutting part, the sewing fabric is cut into several samples along the several through slots 19. After the cutting is completed, the covering rack 17 is retracted and the cut samples can be taken out.

[0032] The above, such as Figure 6 As shown, the cutting part includes a sliding frame 20 and a driving member 22. The sliding frame 20 is slidably installed inside the cutting frame 15. A plurality of cutting knives 21 are installed on the sliding frame 20. The plurality of cutting knives 21 correspond one-to-one to the plurality of through slots 19 on the feeding frame 16. The cutting knives 21 are located inside the through slots 19. The cutting knives 21 are in the transition zone. A driving member 22 is installed inside the cutting frame 15 for driving the sliding frame 20 to move inside the cutting frame 15.

[0033] Among them, the driving component 22 is composed of a motor, an adjusting screw and an adjusting nut. Specifically, when cutting the sewing fabric, the driving component 22 can be turned on, that is, the motor is started to drive the adjusting screw to rotate, and the adjusting screw drives the adjusting nut to move. The adjusting nut is fixedly connected to the sliding frame 20, thereby driving the sliding frame 20 to move. The movement of the sliding frame 20 can drive the cutting knife 21 to move, thereby cutting the sewing fabric through the cutting knife 21.

[0034] The working principle or usage process of this application is as follows: When detecting the tension of a sewing fabric, the sewing fabric is first placed in the loading area on the loading rack 16, and then the second driving member 18 is started. The second driving member 18 pushes the covering rack 17 to move until the covering rack 17 moves above the loading rack 16, and the covering rack 17 and the loading rack 16 form a whole, thereby fixing the sewing fabric. At this time, the driving member 22 is turned on, that is, the motor is started to drive the adjusting screw to rotate, and the adjusting screw drives the adjusting nut to move. The adjusting nut is fixedly connected to the sliding rack 20, thereby driving the sliding rack 20 to move. The movement of the sliding rack 20 can drive the cutting knife 21 to move, so that the sewing fabric is cut by the cutting knife 21, thereby cutting the sewing fabric along the several through slots 19 into several samples. After cutting is completed, the covering rack 17 is retracted and the cut samples can be taken out.

[0035] When testing it, one of the samples is moved into the position of the tension tester 2, and the two ends of the sample are placed between the two clamping seats 4 respectively. When clamping the sample, one end of the sample is first placed between the two sliding jaws 7, and then the two first driving members 11 are started synchronously. The two first driving members 11 simultaneously drive the two clamping blocks 9 to move until they pass through the V-groove setting of the clamping block 9. With the cooperation of the inclined surface of the sliding jaw 7, the two sliding jaws 7 are simultaneously pushed to move in the positioning frame 6 until the clamping plate 14 is tightly abutted against the sample, thereby clamping the sample. At this time, the first driving member 11 can be closed and locked, and the test of the sample can be started.

[0036] During testing, the tension detector 2 is turned on by the control device body 3. The sample is subjected to tension by moving the movable end of the tension detector 2, and the stretching speed is set. During the testing process, the tension sensor 5 is provided with a signal transmitter, and the control device body 3 is provided with a matching signal receiver. After the tension sensor 5 detects the corresponding data, it will be sent to the signal receiver via the signal transmitter. At this time, the control device body 3 can analyze the tension of the sample based on this data, and perform real-time detection on this data. The tension data is converted into electrical signals. After processing, these electrical signals can be converted into digital or analog signals and recorded for subsequent analysis. By analyzing the tension data, the tension that the sewing fabric can withstand is determined until the sample is broken. During the process of testing the tension of the sample, the sliding clamp 7 is subjected to tension. Through the cooperation of the limit slide 12 and the slide groove 13, under the action of the clamping block 9, the stability of the sliding clamp 7 when subjected to tension perpendicular to the moving direction is improved, thereby improving the accuracy of the test.

[0037] After the test is completed, when it is necessary to take out the broken sample, retract the first driving member 11 to move the clamping block 9. Under the action of the spring 8, the sliding clamping jaw 7 can be moved back to its original position, and then the broken sample is taken out. After the broken sample is taken down, the next sample is clamped and the above steps are repeated to test multiple samples. The breaking strength and deformation rate data of multiple samples cut from the same sewing fabric can indirectly reflect the tension of the sewing fabric, thereby optimizing the processing quality, improving the sewing efficiency and the quality of the stitches during sewing through the tension data of the sewing fabric.
