Description

Technical Field

[0001] The present invention relates to the technical field of textile fabric detection, and particularly to a deformation and tear detection system for textile fabrics. Background Art

[0002] The inspection of textile fabrics is divided into three aspects, and the relatively important one is the physical indicators: yarn count, density, weight per square meter, breaking strength, tearing strength, anti-slip, dimensional change rate after washing, dimensional change rate after dry cleaning, pilling, light fastness, light and perspiration composite fastness, ironing fastness, wet rubbing fastness. Therefore, textile fabrics need to be subjected to deformation and tear detection before leaving the factory.

[0003] For example, a deformation and tear detection device for a textile fabric with the patent number CN202210432600.X includes a base platform, and a first column is fixedly connected to the base platform. A first airbag is fixedly sleeved on the outer surface of the first column. Although it is convenient to detect the deformation and tear characteristics of the fabric in a circular state, in the comparative document, the method of expanding and internally supporting the textile fabric by multiple airbags, due to the airbags being distributed at different positions, it is easy to have uneven inflation of the airbags when supplying gas, resulting in different degrees of expansion of the airbags at different positions, causing uneven pressure at the internally supported position of the woven fabric and leading to poor accuracy in detecting deformation and tearing. Moreover, in the comparative document, the method of using pneumatic control to expand the airbag has poor control over the expansion size of the airbag during inflation due to the deformation process of the airbag.

[0004] At the same time, in the comparative document, the textile fabric can only be installed in a top-down manner, and the textile fabric after the detection can only be replaced by taking it out from the upper position. Since the installation and taking process of the textile fabric is relatively cumbersome, it occupies a lot of replacement time and affects the detection efficiency. Moreover, the traditional technology needs to design corresponding separate power sources for the support structures at different positions, and it is easy to cause the power structures on both sides to be out of sync during use, resulting in interference in the support ability or insufficient support ability. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art, such as poor accuracy in detecting deformation and tearing due to uneven pressure at the internally supported position of the textile fabric, poor control over the expansion size of the airbag during inflation due to the deformation process of the airbag, the relatively cumbersome installation and taking process of the textile fabric, occupying a lot of replacement time and affecting the detection efficiency, and the easy occurrence of out-of-sync of the power structures on both sides, resulting in interference in the support ability or insufficient support ability, and to propose a deformation and tear detection system for textile fabrics.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

A plurality of external gears are meshed with the inner side of the inner wall of the toothed ring. An internal gear is fixedly connected to the front side of the rotating shaft inside the external gear. A rack is meshed with one side of the outer wall of the internal gear. A baffle is fixedly connected to one side of the outer wall of the rack. A first spring is arranged outside the baffle. The two sides of the first spring are fixedly connected with the baffle and the vertical cylinder respectively. The outer ends of the racks are fixedly connected with push plates. The outer ends of the push plates are in contact with the inner wall of the textile fabric.

[0010] Preferably, a vertical cylinder is arranged at the center inside the bottom plate. A circular through hole larger than the diameter of the vertical cylinder is processed at the center of the bottom plate, and the lower end of the outer wall of the vertical cylinder penetrates through the central through hole of the bottom plate.

[0011] Preferably, the support assembly includes a card slot, an end plate, a sliding rod, a second spring, and a pressing block;

[0012] A plurality of the sliding rods are respectively slidably connected inside the sleeves and inside the two sides of the bottom plate. The inner ends of the sliding rods are fixedly connected with pressing blocks. The outer walls of the pressing blocks are pressed against the inner walls of the card slots. A plurality of the card slots are respectively processed below the left and right ends of the vertical cylinder and the motor box. Second springs are arranged outside the sliding rods. The two ends of the upper second spring are respectively fixedly connected with the sliding rod and the sleeve. The two ends of the lower second spring are respectively fixedly connected with the sliding rod and the bottom plate.

[0013] Preferably, a tapered groove with a tangent angle consistent with the outer wall of the pressing block is processed on the inner wall of the card slot.

[0014] Preferably, support feet are fixedly connected to the four corners of the lower end of the bottom plate.

[0015] Preferably, the linkage assembly includes a roller, a thin rope, a first gear, a bevel gear set, a second motor, a second gear, and a roller;

[0016] A plurality of the second motors are respectively fixedly connected to the centers of the outer ends of the outer walls of the columns. The output shafts of the second motors are fixedly connected to the input shafts of the bevel gear sets. The ends of the output shafts of the bevel gear sets are fixedly connected with second gears.

[0017] Preferably, the textile fabric is annularly sleeved on the outer wall of the vertical cylinder.

[0018] A deformation and tear detection system for a textile fabric proposed by the present invention has the beneficial effects that:

[0019] Through the cooperation among the first motor, the toothed ring, the connecting rod, the rack, the push plate, the internal gear and the external gear, when the first motor is started, the output shaft of the first motor can drive the toothed ring to rotate through the rotating shaft and the connecting rod. Then, the toothed ring can drive the rack to move outwards through the internal gear and the external gear, so that the rack can drive the push plate to move outwards and press against the inner wall of the textile fabric, expanding the textile fabric, realizing the detection of the deformation and tear of the textile fabric, and enabling multiple racks and the driving push plates to expand outwards synchronously, effectively avoiding the problem of poor accuracy in detecting deformation and tear caused by uneven pressure at the inner support position of the textile fabric;

[0020] Through the cooperation among the toothed ring, the rack, the external gear and the internal gear, during the transmission process between the toothed ring and the rack in this case, since the toothed ring can drive the rack to move through the cooperation of the internal gear and the external gear, and since the toothed ring meshes with the external gear, and the external gear needs to drive the rack through the internal gear, and the number of teeth of the external gear is greater than that of the internal gear, there is a decelerating transmission ratio between the toothed ring and the rack, making the distance control more accurate when the rack expands outwards, effectively avoiding the problem of poor control of the expansion size of the airbag during its inflation process due to the deformation process of the airbag;

[0021] Through the cooperation among the motor box, the vertical cylinder, the textile fabric, the first motor and the bottom plate, the support of the motor box and the vertical cylinder is transferred from below to above. At this time, after controlling the first motor to retract, the textile fabric can fall off from the outer wall of the vertical cylinder and the through holes of the bottom plate, completing automatic blanking. After the blanking is completed, the support of the motor box and the vertical cylinder is transferred from above to below again, and the textile fabric can be installed again, effectively avoiding the problem that the installation and taking process of the textile fabric is relatively cumbersome, occupying a lot of replacement time and affecting the detection efficiency;

[0022] Through the cooperation among the second motor, the roller, the sliding rod, the second spring and the thin rope, when the second motor is started, the second motor can drive the first gear and the second gear to rotate, so that the rollers on both sides can control the corresponding sliding rods to move horizontally through the thin rope and the second spring, enabling a certain linkage ability between the upper and lower sliding rods, effectively avoiding the problem that the power structures on both sides are prone to being asynchronous, resulting in interference in the supporting ability or insufficient supporting ability.

Detailed Embodiment

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] Refer to the attached Figures 1-6: In this embodiment, a deformation and tear detection system for textile fabrics includes a bottom plate 1 and a vertical cylinder 2. A motor box 9 is fixedly connected to the upper end of the vertical cylinder 2. Columns 10 are fixedly connected to the upper ends of the left and right sides of the bottom plate 1.

Support assemblies 4 are installed inside the sleeves 8 and inside the left and right sides of the bottom plate 1. A linkage assembly 5 is installed inside the columns 10. A vertical cylinder 2 is provided at the center of the bottom plate 1. A circular through hole larger than the diameter of the vertical cylinder 2 is machined at the center of the bottom plate 1. The lower end of the outer wall of the vertical cylinder 2 penetrates through the central through hole of the bottom plate 1. Support feet 6 are fixedly connected to the four corners of the lower end of the bottom plate 1. The textile fabric 7 is annularly sleeved on the outer wall of the vertical cylinder 2.

[0032] Refer to the attached Figures 1-6 : In this embodiment, the extrusion assembly 3 includes a rotating shaft 3a1, a first motor 3a2, a rack 3a3, a baffle 3a4, a toothed ring 3a5, a first spring 3a6, a connecting rod 3a7, an external gear 3a8, an internal gear 3a9, and a push plate 3a10;

[0033] The first motor 3a2 is fixedly connected to the center inside the first motor box 9. The models of the first motor 3a2 and the second motor 5a5 can be determined according to specific usage conditions. The end of the output shaft of the first motor 3a2 is fixedly connected to a rotating shaft 3a1. The outer wall of the rotating shaft 3a1 is fixedly connected to a toothed ring 3a5 through a plurality of connecting rods 3a7. A plurality of external gears 3a8 are meshed with the inner side of the inner wall of the toothed ring 3a5. An internal gear 3a9 is fixedly connected to the front side of the rotating shaft inside the external gear 3a8. A rack 3a3 is meshed with one side of the outer wall of the internal gear 3a9. A baffle 3a4 is fixedly connected to one side of the outer wall of the rack 3a3. A first spring 3a6 is arranged outside the baffle 3a4. The spring constant of the first spring 3a6 can be determined according to specific usage conditions. The two sides of the first spring 3a6 are fixedly connected to the baffle 3a4 and the vertical cylinder 2 respectively. The outer ends of the racks 3a3 are fixedly connected to push plates 3a10. The outer ends of the push plates 3a10 are in contact with the inner wall of the textile fabric 7;

[0034] Through the cooperation among the first motor 3a2, the toothed ring 3a5, the connecting rod 3a7, the rack 3a3, the push plate 3a10, the internal gear 3a9, and the external gear 3a8, when the first motor 3a2 is started, the output shaft of the first motor 3a2 can drive the toothed ring 3a5 to rotate through the rotating shaft 3a1 and the connecting rod 3a7. Then, the toothed ring 3a5 can drive the rack 3a3 to move outward through the internal gear 3a9 and the external gear 3a8, so that the rack 3a3 can drive the push plate 3a10 to move outward and press against the inner wall of the textile fabric 7, expanding the textile fabric 7, realizing the detection of the deformation and tear of the textile fabric 7, and enabling multiple racks 3a3 and the driven push plates 3a10 to expand and move outward synchronously, effectively avoiding the problem of poor detection accuracy of deformation and tear caused by uneven pressure at the inner support position of the textile fabric 7;

[0035] Through the cooperation among the gear ring 3a5, the rack 3a3, the external gear 3a8 and the internal gear 3a9, during the transmission process of the gear ring 3a5 and the rack 3a3 in this case, since the gear ring 3a5 can drive the rack 3a3 to move through the cooperation of the internal gear 3a9 and the external gear 3a8, and the gear meshed with the gear ring 3a5 is the external gear 3a8, while the external gear 3a8 needs to drive the rack 3a3 through the internal gear 3a9, and the number of teeth of the external gear 3a8 is greater than that of the internal gear 3a9, a reduction transmission ratio is formed between the gear ring 3a5 and the rack 3a3, making the distance control more accurate when the rack 3a3 expands outwards, effectively avoiding the problem that the control of the expansion size of the airbag is poor during the inflation process due to the deformation process of the airbag.

[0036] Refer to the appendix Figures 1-6 In this embodiment, the support assembly 4 includes a card slot 4a1, an end plate 4a2, a slide rod 4a3, a second spring 4a4 and a pressing block 4a5;

[0037] A plurality of slide rods 4a3 are respectively slidably connected inside the sleeve 8 and on both sides inside the bottom plate 1. The inner ends of the slide rods 4a3 are fixedly connected with pressing blocks 4a5, and the outer walls of the pressing blocks 4a5 are extruded against the inner walls of the card slots 4a1. A plurality of card slots 4a1 are respectively processed below the left and right ends of the vertical cylinder 2 and the motor box 9. Second springs 4a4 are arranged on the outer sides of the slide rods 4a3, and the elastic coefficient of the second springs 4a4 can be determined according to specific usage conditions. The two ends of the upper second spring 4a4 are respectively fixedly connected with the slide rod 4a3 and the sleeve 8, and the two ends of the lower second spring 4a4 are respectively fixedly connected with the slide rod 4a3 and the bottom plate 1. The inner wall of the card slot 4a1 is processed with a conical groove having the same tangent angle as the outer wall of the pressing block 4a5;

[0038] Through the cooperation among the motor box 9, the vertical cylinder 2, the textile fabric 7, the first motor 3a2 and the bottom plate 1, the support of the motor box 9 and the vertical cylinder 2 is transferred from the lower part to the upper part. At this time, after controlling the first motor 3a2 to retract, the textile fabric 7 can fall off from the outer wall of the vertical cylinder 2 and the through holes of the bottom plate 1, and automatic blanking can be completed. After the blanking is completed, the support of the motor box 9 and the vertical cylinder 2 is transferred from the upper part to the lower part again, and the textile fabric 7 can be installed again, effectively avoiding the problem that the installation and taking process of the textile fabric 7 is relatively cumbersome, occupying a lot of replacement time and affecting the detection efficiency.

[0039] Refer to the appendix Figures 1-6 In this embodiment, the linkage assembly 5 includes a roller 5a1, a thin rope 5a2, a first gear 5a3, a bevel gear set 5a4, a second motor 5a5, a second gear 5a6 and a roller 5a7;

[0040] A plurality of second motors 5a5 are respectively fixedly connected to the outer end center of the outer wall of the column 10. The output shafts of the second motors 5a5 are fixedly connected to the input shafts of the bevel gear sets 5a4. The ends of the thin ropes 5a2 are wound around the inner sides of the rollers 5a7. The ends of the output shafts of the bevel gear sets 5a4 are fixedly connected with second gears 5a6. Both the upper and lower sides of the outer walls of the second gears 5a6 are meshed with first gears 5a3. The rear parts of the inner shafts of the first gears 5a3 are fixedly connected with rollers 5a7. The outer walls of the rollers 5a7 are wound with thin ropes 5a2. The left and right sides of the outer walls of the ends of the thin ropes 5a2 are in contact with the rollers 5a1. The inner shafts of the rollers 5a1 are rotatably connected to the column 10. The outer walls of the thin ropes 5a2 are slidably connected to the inner walls of the column 10 and the sleeve 8. And the outer ends of the thin ropes 5a2 are respectively fixedly connected with the upper and lower slide rods 4a3;

[0041] Through the cooperation among the second motor 5a5, the roller 5a7, the slide rod 4a3, the second spring 4a4 and the thin rope 5a2, when the second motor 5a5 is started, the second motor 5a5 can drive the first gear 5a3 and the second gear 5a6 to rotate, so that the rollers 5a7 on both sides can control the corresponding slide rods 4a3 to perform corresponding lateral movements through the thin ropes 5a2 and the second spring 4a4, enabling a certain linkage ability between the upper and lower slide rods 4a3, effectively avoiding the problem that the power structures on both sides are prone to being asynchronous, resulting in interference in the supporting ability or insufficient supporting ability.

[0042] Working principle:

[0043] When the deformation and tear detection system of this textile fabric is needed for use, first, the user can assemble the overall structure as shown in the figure. After the assembly is completed, the user can place the overall structure at the corresponding platform. Before use, the user can put the annular textile fabric 7 on the outer wall of the vertical cylinder 2 from above the outer walls of the vertical cylinder 2 and the motor box 9. Subsequently, start the first motor 3a2, so that the output shaft of the first motor 3a2 can drive the toothed ring 3a5 to rotate through the rotating shaft 3a1 and the connecting rod 3a7. Then, the toothed ring 3a5 can drive the rack 3a3 to move outward through the internal gear 3a9 and the external gear 3a8, so that the rack 3a3 can drive the push plate 3a10 to move outward and press against the inner wall of the textile fabric 7, causing the textile fabric 7 to expand, realizing the detection of the deformation and tear of the textile fabric 7. Compared with the method in the comparative document of controlling the expansion of the textile fabric 7 by multiple airbags, since the airbags are distributed at different positions, it is easy to have uneven inflation of the airbags during air supply, resulting in different degrees of inflation of the airbags at different positions, causing uneven pressure at the inner support position of the woven fabric 7 and poor accuracy in the detection of deformation and tear. Therefore, in this case, the toothed ring 3a5 and the rack 3a3 are designed to make multiple racks 3a3 and the driving push plate 3a10 expand and move outward synchronously, effectively avoiding the problem of poor accuracy in the detection of deformation and tear caused by uneven pressure at the inner support position of the textile fabric 7. And because in the transmission process of the toothed ring 3a5 and the rack 3a3 in this case, the toothed ring 3a5 can drive the rack 3a3 to move through the cooperation of the internal gear 3a9 and the external gear 3a8. Since the external gear 3a8 meshes with the toothed ring 3a5, and the external gear 3a8 needs to drive the rack 3a3 through the internal gear 3a9, and the number of teeth of the external gear 3a8 is greater than the number of teeth of the internal gear 3a9, there is a deceleration transmission ratio between the toothed ring 3a5 and the rack 3a3, making the distance control more accurate when the rack 3a3 expands outward. Compared with the method of using pneumatic control to expand the airbag in the comparative document, due to the deformation process of the airbag, the control of the expansion size of the airbag during inflation is poor. Therefore, in this case, the cooperation of the internal gear 3a9 and the external gear 3a8 is designed to make the distance control more accurate when the rack 3a3 expands outward, effectively avoiding the problem of poor control of the expansion size of the airbag during inflation due to the deformation process of the airbag.

[0044] Meanwhile, after completing the expansion detection of the textile fabric 7, the user can control the upper and lower slide bars 4a3 to move in the reverse direction, that is, the upper slide bar 4a3 drives the pressing block 4a5 to insert into the inner part of the card slot 4a1, and the pressing block 4a5 of the lower slide bar 4a3 is pulled out from the card slot 4a1, so that the support of the motor box 9 and the vertical cylinder 2 is transferred from the lower part to the upper part. At this time, after controlling the first motor 3a2 to retract, the textile fabric 7 can fall off from the outer wall of the vertical cylinder 2 and the through hole of the bottom plate 1, and automatic blanking can be completed. After the blanking is completed, the support of the motor box 9 and the vertical cylinder 2 is transferred from the upper part to the lower part again, and the textile fabric 7 can be installed again. Compared with the textile fabric 7 in the comparative document, which can only be installed in the top-down manner and can only be replaced by taking it out from the upper position after the detection is completed, since the installation and taking process of the textile fabric 7 is relatively cumbersome, occupying a lot of replacement time and affecting the detection efficiency. Therefore, in this case, the support component 4 is designed to continuously replace the support position so that the textile fabric 7 can fall off from the outer wall of the vertical cylinder 2 and the through hole of the bottom plate 1, and automatic blanking can be completed, effectively avoiding the problem that the installation and taking process of the textile fabric 7 is relatively cumbersome, occupying a lot of replacement time and affecting the detection efficiency. And, since the upper and lower slide bars 4a3 in the support component 4 need to continuously move synchronously in the reverse direction, therefore, in this case, a linkage component 5 is required to start the second motor 5a5, so that the second motor 5a5 can drive the first gear 5a3 and the second gear 5a6 to rotate, so that the roller 5a7 on both sides can control the corresponding slide bar 4a3 to perform corresponding lateral movement through the thin rope 5a2 and the second spring 4a4, so that there is a certain linkage ability between the upper and lower slide bars 4a3. Compared with the traditional technology that requires a corresponding separate power source for the support structures at different positions, it is easy to cause the power structures on both sides to be asynchronous during use, resulting in interference in the support ability or insufficient support ability. Therefore, in this case, the corresponding slide bar 4a3 is controlled to perform corresponding lateral movement through the thin rope 5a2 and the second spring 4a4, so that there is a certain linkage ability between the upper and lower slide bars 4a3, effectively avoiding the problem that it is easy to cause the power structures on both sides to be asynchronous, resulting in interference in the support ability or insufficient support ability.
