Description

Technical Field

[0001] The utility model relates to the technical field of fabric detection devices, and particularly relates to an elastic detection device for yarn-dyed fabrics. Background Art

[0002] The elastic detection device for yarn-dyed fabrics is a special equipment used to test the relaxation, fatigue and elastic recovery performance of yarn-dyed fabrics during the stretching process. The elastic detection device for yarn-dyed fabrics is mainly used to test the deformation degree of yarn-dyed fabrics under the action of external forces, and the ability to restore to the original shape after the external forces are removed, so as to evaluate the elasticity and durability of the fabrics.

[0003] The elastic detection device for yarn-dyed fabrics applies a certain load to the fabric sample to cause deformation, and then measures the recovery degree of the fabric after the external force is removed. During this process, the device will record key data such as the deformation amount and recovery amount of the fabric, and calculate the elastic index of the fabric based on this. The elastic detection device for yarn-dyed fabrics plays an important role in the production process of yarn-dyed fabrics, which can help the staff accurately judge the quality of the elastic performance of the fabrics. By using this device, it can be ensured that the yarn-dyed fabrics can have good elasticity and recovery performance after being made into clothes or other textiles, meeting the needs of consumers.

[0004] However, some devices in the prior art may have deficiencies in fabric fixing and clamping, such as low clamping force or the fabric is easy to fall off or slip during the stretching test, which may affect the accuracy of the test results. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide an elastic detection device for yarn-dyed fabrics to solve the technical problem that some devices in the prior art may have deficiencies in fabric fixing and clamping, such as low clamping force or the fabric is easy to fall off or slip during the stretching test, which may affect the accuracy of the test results.

[0006] To achieve the above object, the present utility model provides the following technical solution: An elastic detection device for a yarn-dyed fabric, comprising a housing. A motor is fixedly installed on the top of the housing. The output end of the motor is fixedly connected to a bidirectional threaded rod. There are two groups of second movable blocks arranged on the bidirectional threaded rod. A fixed block is fixedly connected to one side of the second movable block. A first clamping block is fixedly installed at the bottom of the fixed block. And a regulating screw is rotatably connected to the front surface of the fixed block. A second clamping block is threadedly connected to the regulating screw. An activity groove for cooperating with the regulating screw is opened in the fixed block. The inside of the fixed block is of a cavity structure. And a push plate is arranged on the outside of the fixed block. First racks are fixedly connected to the inner side of the push plate in a symmetrical structure. A piston plate is movably installed in the fixed block. Second racks are fixedly installed on one side of the piston plate in a symmetrical structure. And the second racks are located below the first racks. A gear for cooperating with the first racks and the second racks is rotatably connected in the fixed block. A gas guiding block is fixedly connected to the top of the fixed block. A suction pipe is connected to one side of the gas guiding block. Multiple nozzles for cooperating with the gas guiding block and the fixed block are fixedly connected to the suction pipe. The suction pipe and the nozzles are fixed inside the first clamping block. And an air suction hole for cooperating with the nozzles is opened in the first clamping block. A reinforcing block for cooperating with the air suction hole is arranged on the inner side of the second clamping block. The reinforcing block is a rubber block with a semi-circular structure. And semi-circular convex blocks and semi-circular grooves are arranged between the first clamping block and the second clamping block. The clamping groove between the first clamping block and the second clamping block is of an S-shaped structure.

[0007] By adopting the above technical solution, during use, the fabric body is clamped between the first clamping block and the second clamping block. The second clamping block can be clamped with the first clamping block by adjusting the screw. When the second clamping block approaches the first clamping block, the push plate is extruded. The first rack synchronously moves forward into the fixed block. Through the mutual cooperation between the first rack and the gear, the second rack moves backward. Thereby, the piston plate can be driven to move backward, generating negative pressure in the fixed block. Through the mutual cooperation between the gas guiding block, the suction pipe and the nozzles, gas is drawn into the fixed block. When the nozzles inhale gas, the reinforcing block can be closely attached to the first clamping block, so that the fabric body can be more tightly clamped by the first clamping block and the second clamping block. Secondly, the mutual cooperation between the semi-circular convex blocks and the semi-circular grooves arranged in both the first clamping block and the second clamping block can keep the fabric body stable during the test. And the S-shaped clamping blocks can flexibly adjust the position and angle of the fabric to adapt to fabrics of different shapes and sizes, making the operation more convenient. With this structure, the technical problems in the prior art that some devices may have deficiencies in fabric fixing and clamping, such as low clamping force or the fabric being prone to falling off or slipping during tensile testing, which may affect the accuracy of the test results, can be solved, improving the practicability and flexibility of the entire elastic detection device for the yarn-dyed fabric.

[0008] The present utility model is further configured such that a guide rail is fixedly installed on the left side of the outer shell, and a first slider is slidably connected to the guide rail, and a detection device is installed on the first slider.

[0009] By adopting the above technical solution, the mutual cooperation between the provided guide rail and the first slider enables the first slider to slide on one side of the outer shell, and through the detection device on the first slider, the fabric being tested can be flexibly monitored, thereby analyzing the fabric test results.

[0010] The present utility model is further configured such that a belt is connected to the outside of the output end of the motor, the other end of the belt is connected to a transmission rod, and a lead screw is fixedly connected to the bottom of the transmission rod. The bottom of the lead screw is rotatably connected to the bottom of the outer shell. A first movable block is threadedly connected to the outside of the lead screw. A screw rod is fixedly connected to the outside of the first movable block. A sleeve is threadedly connected to the outside of the screw rod. A connecting rod is rotatably connected to the front of the sleeve, and a tensioning wheel is rotatably connected to one side of the connecting rod.

[0011] By adopting the above technical solution, the provided belt enables the transmission rod and the lead screw to move synchronously with the output end of the motor, so that the first movable block can slide on the lead screw. At the same time, through the mutual cooperation between the sleeve and the screw rod, the position of the sleeve can be flexibly adjusted, enabling the tensioning wheel to better cooperate with the first clamping block and the second clamping block to perform elastic detection on the fabric. When the fabric is clamped by the two groups of first clamping blocks and the second clamping block, the tensioning wheel moves in the middle of the fabric, and cooperates with the bidirectional threaded rod and the second movable block to perform elastic detection on the fabric.

[0012] The present utility model is further configured such that a convex ring is fixedly connected to one end of the connecting rod, and a rotating groove for cooperating with the convex ring is provided on the sleeve.

[0013] By adopting the above technical solution, the mutual cooperation between the provided convex ring and the rotating groove is beneficial for the connecting rod and the sleeve to rotate flexibly, and when the sleeve rotates, it will not drive the connecting rod to move synchronously.

[0014] The present utility model is further configured such that a second slider is fixedly installed on the outside of the first movable block. One end of the second slider is connected to the outer shell, and a second sliding groove for cooperating with the second slider is provided on the outside of the outer shell.

[0015] By adopting the above technical solution, the mutual cooperation between the provided second slider and the second sliding groove enables the first movable block to slide smoothly on the lead screw, and can play a role in limiting the first movable block.

[0016] The present utility model is further configured such that a first sliding groove for cooperating with the second movable block is provided on the front of the outer shell, and a limiting block is fixedly installed between the bidirectional threaded rods.

[0017] By adopting the above technical solution, the arranged limiting block enables the second movable block to slide synchronously and flexibly on the bidirectional threaded rod, and the first chute facilitates the second movable block to reciprocate up and down stably within the housing.

[0018] The utility model is further arranged such that limiting plates are rotatably connected to both sides of the gear, support blocks are fixedly connected between the fixed block and the limiting plates, and the first rack and the second rack are located on both sides of the adjusting screw rod and the movable groove.

[0019] By adopting the above technical solution, the mutual cooperation between the arranged limiting plates and the support blocks can fix the gear for use between the first rack and the second rack. When the first rack and the second rack are located on both sides of the adjusting screw rod and the movable groove, it is beneficial for the first rack to flexibly move within the fixed block while enabling the second rack to move within the movable block, thereby driving the piston plate to move within the fixed block and changing the air pressure within the fixed block.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. In the utility model, the fabric body is clamped between the first clamping block and the second clamping block. The second clamping block can be clamped with the first clamping block by adjusting the screw rod. When the second clamping block approaches the first clamping block, the push plate is extruded, and the first rack synchronously moves forward into the fixed block. Through the mutual cooperation between the first rack and the gear, the second rack moves backward, thereby driving the piston plate to move backward, generating negative pressure within the fixed block. Through the mutual cooperation between the air guide block, the suction pipe, and the nozzle, gas is drawn into the fixed block. When the nozzle inhales, the reinforcing block can closely fit with the first clamping block, so that the fabric body can be more tightly clamped by the first clamping block and the second clamping block. Secondly, semi-circular convex blocks and semi-circular grooves are arranged in both the first clamping block and the second clamping block to enable the fabric body to remain stable during the test. Moreover, the S-shaped clamping block can flexibly adjust the position and angle of the fabric to adapt to fabrics of different shapes and sizes, making the operation more convenient. With this structure, it can solve the technical problems in the prior art that some devices may have deficiencies in fabric fixing and clamping, such as low clamping force or the fabric being prone to falling off or slipping during tensile testing, which may affect the accuracy of the test results, and improve the practicality and flexibility of the entire elastic detection device for yarn-dyed fabrics.

[0022] 2. The belt provided in the utility model enables the transmission rod and the lead screw to move synchronously with the output end of the motor, so that the first movable block can slide on the lead screw. At the same time, through the mutual cooperation between the sleeve and the screw rod, the position of the sleeve can be flexibly adjusted, enabling the tensioning wheel to better cooperate with the first clamping block and the second clamping block to perform elastic detection on the fabric. When the fabric is clamped by the two groups of first clamping blocks and the second clamping block, the tensioning wheel moves in the middle of the fabric, and the elastic detection of the fabric is carried out in cooperation with the bidirectional threaded rod and the second movable block.

[0032] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0033] The embodiments of the present utility model will be described below according to its overall structure.

[0034] A device for detecting the elasticity of a yarn-dyed fabric, as Figures 1-8 shown, includes a housing 1. A motor 2 is fixedly installed at the top of the housing 1. The output end of the motor 2 is fixedly connected to a bidirectional threaded rod 16. Two groups of second movable blocks 17 are arranged on the bidirectional threaded rod 16. One side of the second movable block 17 is fixedly connected to a fixed block 15. A first clamping block 7 is fixedly installed at the bottom of the fixed block 15. And a regulating screw 21 is rotatably connected to the front surface of the fixed block 15. A second clamping block 8 is threadedly connected to the regulating screw 21. An activity groove for cooperating with the regulating screw 21 is formed in the fixed block 15. The inside of the fixed block 15 is of a cavity structure. And a push plate 28 is arranged on the outside of the fixed block 15. First racks 29 are fixedly connected to the inner side of the push plate 28 in a symmetrical structure. A piston plate 36 is movably installed in the fixed block 15. Second racks 33 are fixedly installed on one side of the piston plate 36 in a symmetrical structure. And the second racks 33 are located below the first racks 29. A gear 30 for cooperating with the first racks 29 and the second racks 33 is rotatably connected in the fixed block 15. A gas guide block 27 is fixedly connected to the top of the fixed block 15. An air extraction pipe 34 is connected to one side of the gas guide block 27. A plurality of nozzles 35 for cooperating with the gas guide block 27 and the fixed block 15 are fixedly connected to the air extraction pipe 34. The air extraction pipe 34 and the nozzles 35 are fixed inside the first clamping block 7. And an air extraction hole 19 for cooperating with the nozzles 35 is formed in the first clamping block 7. A reinforcing block 20 for cooperating with the air extraction hole 19 is arranged on the inner side of the second clamping block 8. The reinforcing block 20 is a rubber block with a semi-circular structure. And semi-circular convex blocks and semi-circular grooves are arranged between the first clamping block 7 and the second clamping block 8. The clamping groove between the first clamping block 7 and the second clamping block 8 is of an S-shaped structure.

[0035] In use, the fabric body is clamped between the first clamping block 7 and the second clamping block 8. By adjusting the screw rod 21, the second clamping block 8 can be clamped with the first clamping block 7. When the second clamping block 8 approaches the first clamping block 7, the push plate 28 is extruded, and the first rack 29 synchronously moves forward into the fixed block 15. Through the mutual cooperation between the first rack 29 and the gear 30, the second rack 33 moves backward, thereby driving the piston plate 36 to move backward, generating negative pressure in the fixed block 15. Through the mutual cooperation between the air guide block 27, the suction pipe 34 and the nozzle 35, gas is drawn into the fixed block 15. When the nozzle 35 sucks air, the reinforcing block 20 can be closely attached to the first clamping block 7, so that the fabric body can be more tightly clamped by the first clamping block 7 and the second clamping block 8. Secondly, through the mutual cooperation between the semi-circular convex blocks and the semi-circular grooves provided in both the first clamping block 7 and the second clamping block 8, the fabric body can be kept stable during the test, and the S-shaped clamping blocks can flexibly adjust the position and angle of the fabric to adapt to fabrics of different shapes and sizes, making the operation more convenient. With this structure, it can solve the technical problems that some devices in the prior art may have deficiencies in fabric fixing and clamping, such as low clamping force or the fabric being easily detached or slipping off during tensile testing, which may affect the accuracy of the test results, and improve the practicability and flexibility of the entire elastic detection device for yarn-dyed fabrics.

[0036] Furthermore, the mutual cooperation between the guide rail 3 and the first slider 5 enables the first slider 5 to slide on one side of the housing 1. And through the detection device on the first slider 5, the fabric being tested can be flexibly monitored, thereby analyzing the fabric test results. And the belt 9 enables the transmission rod 10 and the lead screw 11 to move synchronously with the output end of the motor 2, so that the first movable block 12 can slide on the lead screw 11. At the same time, through the mutual cooperation between the sleeve 13 and the screw rod 26, the position of the sleeve 13 can be flexibly adjusted, enabling the tension pulley 4 to better cooperate with the first clamping block 7 and the second clamping block 8 to perform elastic detection on the fabric. When the fabric is clamped by the two groups of first clamping blocks 7 and second clamping blocks 8, the tension pulley 4 moves in the middle of the fabric, cooperating with the bidirectional threaded rod 16 and the second movable block 17 to perform elastic detection on the fabric. The mutual cooperation between the convex ring 25 and the rotating groove 24 is beneficial for the connecting rod 14 and the sleeve 13 to rotate flexibly, and when the sleeve 13 rotates, it will not drive the connecting rod 14 to move synchronously.

[0037] In this embodiment, the mutual cooperation between the second slider 23 and the second chute 22 enables the first movable block 12 to slide smoothly on the lead screw 11, which can play a role in limiting the first movable block 12. By providing the limiting block 18, the second movable block 17 can slide synchronously and flexibly on the bidirectional threaded rod 16. Moreover, the first chute 6 is conducive to the second movable block 17 moving up and down reciprocally and smoothly in the housing 1. Finally, the mutual cooperation between the limiting plate 31 and the support block 32 can fix the gear 30 for use between the first rack 29 and the second rack 33. When the first rack 29 and the second rack 33 are located on both sides of the adjusting screw 21 and the movable groove, it is conducive to the first rack 29 moving flexibly in the fixed block 15 while enabling the second rack 33 to drive the piston plate 36 to move in the fixed block 15, so as to change the air pressure in the fixed block 15.
