Description

Technical Field

[0001] This invention relates to the field of textile quality inspection, specifically to a device and method for testing the strength performance of textile production. Background Technology

[0002] Textiles are products made through textile processing, including yarns, woven fabrics, knitted fabrics, and braided fabrics. They are divided into two main categories: woven fabrics and knitted fabrics. Cloth bags made from textiles have a wide range of applications in daily life. Compared to plastic bags, textile bags have significant advantages in durability and load-bearing capacity, and are also more aesthetically pleasing. Compared to leather bags, textile bags are cheaper to manufacture and simpler to produce.

[0003] In the manufacturing process of textiles, it is necessary to test the strength of textile bags. In the traditional method of testing the strength of bags, a heavy object is often added directly to the bag, and the maximum weight that the bag can bear when it is damaged is then observed to test the strength of the textile bag. However, in actual use, the items carried by the bags are often irregular. In some cases, the pressure of the items on the bottom of the textile bag is greater, in others, the pressure on the sides of the textile bag is greater, and in some cases, the pressure exerted by the items on localized parts of the textile bag is greater. That is, due to the irregular shape of the heavy object, the pressure on the tested area of ​​the bag is uneven, and targeted testing of the tested surface is not possible.

[0004] Therefore, it is necessary to provide a testing device and method for testing the strength performance of textile production in order to solve the above-mentioned technical problems. Summary of the Invention

[0017] Compared with related technologies, the textile production strength performance testing device provided by the present invention has the following beneficial effects:

[0018] 1. This invention places the upper side of the woven bag between the clamping slider and the clamping block, and then rotates the clamping screw to move the clamping slider closer to the clamping block. The woven bag is clamped by the teeth on the clamping slider and the clamping block.

[0020] 3. The magnetic wrench of the present invention extends into the mounting through hole and attracts the locking groove 653. Then, the locking key 653 is moved out of the locking groove 652 on the rack groove 651. Subsequently, the magnetic wrench drives the abutment gear 663 and the locking key 653 to rotate as a whole. The abutment gear 663 drives the abutment rack 661 to move. The abutment rack 661 drives the abutment rod 662 to move, making the abutment rod 662 more prominent than the other abutment rods 662. Then, the pressure test is performed on the side of the textile bag to obtain the local strength of the woven bag. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0034] like Figure 1 As shown, the present invention provides a textile production strength performance testing device, including a mounting base plate 1, wherein support legs 11 are fixedly installed at the four corners of the lower end of the mounting base plate 1.

[0035] like Figure 1 , Figure 7 and Figure 8As shown, a detection clamping hole 12 is provided in the middle of the mounting base plate 1. The detection clamping hole 12 is a rectangular hole. A bag clamping device 2 is fixedly installed along the edge line perpendicular to the rectangular hole. The bag clamping device 2 includes a vertical sliding plate 21, an extension sliding plate 22, a clamping screw 23, a clamping slider 24, and a clamping rack 25. The upper end of the mounting base plate 1 is slidably connected to the vertical sliding plate 21, which slides along the direction perpendicular to the edge line of the detection clamping hole 12. The upper part of the vertical sliding plate 21... A second sliding groove 211 perpendicular to the edge of the detection clamping hole 12 is provided at one end. An extension sliding plate 22 is slidably connected in the second sliding groove 211. A third sliding groove 221 is provided on the extension sliding plate 22. A clamping slider 24 is slidably connected in the third sliding groove 221. An empty groove 222 is provided at the upper end of the extension sliding plate 221. A screw mounting block 223 is fixedly installed at the end of the empty groove 222 away from the clamping slider 24. A clamping screw 23 is rotatably connected to block 223, and the clamping screw 23 is threadedly connected to the clamping slider 24. A clamping block 224 is fixedly installed at the lower end of the extension sliding plate 22 corresponding to the position of the clamping slider 24. The clamping block 224 and the clamping slider 24 are machined with interlocking protrusions. A first control hole 225 is opened at the position corresponding to the empty slot 222 on the extension sliding plate 22. A first control rod 226 is slidably connected to the first control hole 225 in the vertical direction. The vertical sliding plate 21 has through holes arranged in a row corresponding to the first control hole 225. The first control rod 226 is inserted into one of the through holes. A clamping rack 25 is fixedly installed at the end of the vertical sliding plate 21 away from the detection clamping hole 12. A synchronization mechanism 3 is provided around all the cloth bag clamping devices 2 at the upper end of the mounting base plate 1. The clamping rack 25 and the synchronization mechanism 3 mesh with each other. A detection unit 4 for detecting the tensile strength of textiles is also installed on the mounting base plate 1.

[0036] It should be noted that during the strength testing of the textile bag, the textile bag is first clamped and fixed by the bag clamping device 2. Then, the strength of the textile bag is tested by the testing unit 4. During the clamping and fixing of the bag by the bag clamping device 2, the synchronization mechanism 3 first controls the clamping rack 25 to move along the direction perpendicular to the edge of the testing clamping hole 12. The clamping rack 25 drives the bag clamping device 2 to move along the direction perpendicular to the edge of the testing clamping hole 12 until all the clamping blocks 224 in the bag clamping device 2 are in contact with the textile bag. The dimensions of the ports correspond, and then the upper side of the textile bag is placed between the clamping slider 24 and the clamping block 224. Then, by rotating the clamping screw 23, the clamping slider 24 is moved closer to the clamping block 224. The textile bag is clamped by the teeth on the clamping slider 24 and the clamping block 224. At the same time, by pulling out the first control rod 226 from the through hole on the vertical sliding plate 21, the sliding plate 22 is slid extended, thereby adjusting the position of the clamping block 224 in the single bag clamping device 2. In this way, textile bags of different sizes and types can be effectively clamped.

[0037] like Figure 2 As shown, a spreading device 5 is provided at the four corners of the detection clamping hole 12 at a 45-degree angle to the detection clamping hole 12. The spreading device 5 includes a spreading slider 51, a spreading rod 52, and a spreading rack 53. The spreading slider 51 is slidably connected to the four corners of the detection clamping hole 12 at a 45-degree angle to the detection clamping hole 12 on the mounting base plate 1. The spreading rod 52 is fixedly connected to the side of the spreading slider 51 facing the detection clamping hole 12. The spreading rod 52 is an L-shaped rod, and the vertical section of the spreading rod 52 extends into the detection clamping hole 12. The spreading rack 53 is fixedly installed at the end of the spreading slider 51 away from the detection clamping hole 12. The spreading rack 53 meshes with the synchronization mechanism 3.

[0038] It should be noted that, in order to ensure that the upper end of the textile bag can be opened as much as possible, the above function is achieved by the opening device 5. When the upper seal of the textile bag is opened by the opening device 5, the textile bag first needs to be placed on the outside of the vertical sections of all the opening rods 52. The synchronization mechanism 3 drives the opening rack 53 to move, the opening rack 53 drives the opening slider 51 to move, and the opening slider 51 drives the opening rods 52 to open the textile bag along the four corners of the detection clamping hole 12 and at a 45-degree angle to the detection clamping hole 12.

[0039] like Figure 1 and Figure 2As shown, the synchronization mechanism 3 includes a synchronous pulley 31, a synchronous gear 32, a synchronous belt 33, a synchronous locking rod 34, and a synchronous guide rail 35. The synchronous pulley 31 is located on the extension line of the vertical sliding plate 21 and the expanding slider 51, away from the detection clamping hole 12. The lower end of the synchronous pulley 31 is fixedly connected to the synchronous gear 32, which is rotatably mounted on the upper end of the mounting base plate 1. The synchronous gear 32 meshes with the clamping rack 25 and the expanding rack 53. The synchronous pulleys 31 are synchronously connected by the synchronous belt 33. A synchronous locking rod is provided on the outer side of the synchronous pulley 31. 34. The synchronous guide rail 35 is fixedly mounted on the upper end of the mounting base plate 1. The synchronous guide rail 35 is located on the outer extension line of the synchronous belt 33 track. The synchronous locking rod 34 is an L-shaped rod. The horizontal section of the synchronous locking rod 34 is fixedly connected to the synchronous belt 33, and the vertical section of the synchronous locking rod 34 is slidably connected to the synchronous guide rail 35. Both the synchronous locking rod 34 and the synchronous guide rail 35 are provided with locking holes 341. The locking holes 341 on the synchronous guide rail 35 are evenly distributed along the track of the synchronous guide rail 35. A locking pin 342 is inserted into the locking hole 341 to lock the synchronous locking rod 34 and the synchronous guide rail 35.

[0040] It should be noted that during the process of driving the bag clamping device 2 and the spreading device 5 through the synchronization mechanism 3, the locking pin 342 is pulled out from the locking hole 341, and then the synchronization locking rod 34 moves along the synchronization guide rail 35. The synchronization locking rod 34 drives the synchronization belt 33 to move, the synchronization belt 33 drives the synchronization pulley 31 to rotate, the synchronization pulley 31 drives the synchronization gear 32 to rotate, and the synchronization gear 32 drives the clamping rack 25 and the spreading rack 53 to move. It should be noted that the diameters of the synchronization gear 32 located before and after the detection clamping hole 12, the synchronization gear 32 located to the left and right of the detection clamping hole 12, and the synchronization gear 32 meshing with the spreading rack 53 are all different. This is to ensure that the movement of the bag clamping device 2 and the spreading device 5 in both directions can be kept synchronized. When it is necessary to lock the position of the synchronization locking rod 34, the locking pin 342 is inserted into the locking hole 341 to lock the synchronization locking rod 34.

[0041] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 9 and Figure 10As shown, the detection unit 4 includes a mounting plate 41, a lifting rod 42, a vertical sliding rod 43, and a detection rod 44. The mounting plate 41 is fixedly mounted on the upper end of the detection clamping hole 12, and the middle position of the mounting plate 41 corresponds to the middle position of the detection clamping hole 12. The lifting rod 42 is fixedly installed at the middle position of the lower end of the mounting plate 41. A vertical sliding rod 43 is slidably connected inside the lifting rod 42 along the vertical direction. A second control hole 421 is opened on the lifting rod 42, and a second control rod 422 is slidably connected in the second control hole 421. The vertical sliding rod 43 has slots corresponding to the second control hole 421 and arranged in a row along the vertical direction. The second control rod 422 is inserted into one of the slots. A detection rod 44 is slidably connected inside the vertical sliding rod 43 along the vertical direction. The upper end of the detection rod 44 passes through the upper end of the mounting plate 41, and a force measuring device is fixedly connected to the upper end of the detection rod 44. 441. Each side of the vertical sliding rod 43 has a lateral groove 431. A transmission rack 442 is fixedly connected to the side of the detection rod 44. The transmission rack 442 passes through the lateral groove 431. A transmission gear 432 meshes with the end of the transmission rack 442 away from the detection rod 44. A transmission pulley 433 is coaxially fixedly connected to the transmission gear 432. A transmission belt 434 is rotatably connected to the transmission pulley 433. The transmission pulley 433 rotates... A third control groove 435 is provided on the vertical sliding rod 43, and a third control rod 436 is slidably connected in the third control groove 435. A through hole is provided on any one of the transmission racks 442 in a vertical row. The third control rod 436 is fastened in one of the through holes. A spreading mechanism 6 is connected to the lower end of the vertical sliding rod 43. The transmission pulley 433 is connected to the spreading mechanism 6 through a transmission belt 434.

[0042] like Figure 3 , Figure 4 and Figure 5 As shown, the spreading mechanism 6 includes a spreading base 61, a spreading gear 62, a spreading pulley 63, a spreading rack 64, and a spreading plate 65. The spreading base 61 is fixedly connected to the lower end of the vertical sliding rod 43. The spreading base 61 has a spreading groove 611 along the edge line perpendicular to the detection clamping hole 12. The spreading rack 64 is slidably connected in the spreading groove 611. The spreading gear 62 is meshed on the spreading rack 64. The spreading gear 62 is rotatably connected to the spreading base 61. The spreading pulley 63 is coaxially fixedly connected to the spreading gear 62. The guide pulley 433 and the spreading pulley 63 are connected by a guide belt 434. The spreading plate 65 is fixedly connected to one end of the spreading rack 64 near the edge line of the detection clamping hole 12. An abutment mechanism 66 is provided on the spreading plate 65.

[0043] It should be noted that during the strength test of the textile bag by the detection unit 4, when the bottom of the textile bag is being tested, the second control rod 422 is pulled out from the second control hole 421, and the vertical sliding rod 43 and the detection rod 44 are simultaneously fixed by the third control rod 436. Then, the detection rod 44 and the vertical sliding rod 43 are moved downward in a straight line by a linear lifting device such as a hydraulic cylinder or a linear motor, thereby extending the opening mechanism 6 into the textile bag. When the opening mechanism 6 contacts the bottom of the textile bag, pressure is applied to the bottom of the textile bag, and the change value of the force gauge 441 when the textile bag is damaged is recorded. When the side of the textile bag is being tested, the opening mechanism 6 is extended into the textile bag. Afterwards, the second control rod 422 is used to fix the lifting rod 42 and the vertical sliding rod 43, and the third control rod 436 is pulled out from the third control slot 435. Then, the detection rod 44 is moved downward by the linear lifting device. The detection rod 44 drives the transmission rack 442 to move downward. The transmission rack 442 drives the transmission gear 432 to rotate. The transmission gear 432 drives the transmission pulley 433 to rotate. The transmission pulley 433 drives the opening pulley 63 in the opening mechanism 6 to rotate through the transmission belt 434. The opening pulley 63 drives the opening gear 62 to rotate. The opening gear 62 drives the opening rack 64 to move towards the textile bag. The opening plate 65 drives the abutment mechanism 66 on it to apply pressure to the side of the textile bag. The change value of the force gauge 441 when the textile bag is damaged is recorded.

[0044] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the abutment mechanism 66 includes an abutment rack 661, an abutment rod 662, and an abutment gear 663. The expansion plate 65 has rack grooves 651 arranged in a row. The abutment rack 661 is slidably connected in the rack grooves 651. The toothed edge of the abutment rack 661 meshes with the abutment gear 663. The abutment gear 663 is rotatably connected to the expansion plate 65. The abutment rod 662 is fixedly connected to the end of the abutment rack 661 away from the expansion base 61. The abutment rod 662 is an L-shaped rod. Locking grooves 652 are provided at the lower end of the rack grooves 651 and in the middle of the abutment gear 663. A mounting through hole is provided at the upper end of the rack grooves 651 and directly above the abutment gear 663. A locking key 653 is slidably connected in the locking grooves 652 along the vertical direction. The locking key 653 has polygonal holes and is made of magnetic material.

[0045] It should be noted that when the strength of the textile bag is tested by the contact mechanism 66, pressure is applied to the textile bag by the contact rod 662. When it is necessary to test the local strength of the side of the textile bag, the position of the single contact rod 662 is changed. The specific testing operation is as follows: an external magnetic wrench can be inserted into the mounting through hole and hold the locking groove 653. Then, the locking key 653 is moved out of the locking groove 652 on the rack groove 651. Subsequently, the magnetic wrench drives the contact gear 663 and the locking key 653 to rotate as a whole. The contact gear 663 drives the contact rack 661 to move. The contact rack 661 drives the contact rod 662 to move, making the contact rod 662 more prominent than the other contact rods 662. Then, the pressure of the side of the textile bag is tested to obtain the local strength of the woven bag.

[0046] The present invention also provides a device for testing the strength properties of textiles, comprising the following steps:

[0047] S1: The textile bag needs to be clamped and fixed by the bag clamping device 2. By pulling the first control rod 226 out of the through hole on the vertical sliding plate 21, the sliding plate 22 is extended by sliding, thereby adjusting the position of the clamping block 224 in the single bag clamping device 2 so that the clamping block 224 contacts the outer surface of the textile bag. By rotating the clamping screw 23, the clamping slider 24 moves closer to the clamping block 224. The woven bag is clamped by the teeth on the clamping slider 24 and the clamping block 224. In this way, woven bags of different sizes and types can be effectively clamped.

[0048] S2: The strength of the textile bag is tested by the detection unit 4. During this process, the invention drives the spreading rack 53 to move through the synchronization mechanism 3. The spreading rack 53 drives the spreading slider 51 to move. The spreading slider 51 drives the spreading rod 52 to spread the woven bag along the four corners of the detection clamping hole 12 and at a 45-degree angle to the detection clamping hole 12, so that the detection unit 4 can more easily enter the woven bag.
