Description

Technical Field

[0001] The invention relates to the technical field of elastic fabric detection, in particular to an elastic strength detection device for preparing nylon quick-drying fabric. Background Art

[0002] The elastic strength of fabric is one of the important indicators to measure the quality of fabric. By testing the elastic strength of fabric, we can understand the deformation degree and recovery ability of fabric after stress and evaluate its overall quality. This is of great significance to ensure that consumers buy high-quality textiles. Testing the elastic strength of fabric is to ensure the quality, durability and safety of fabric, while meeting specific application requirements. The elastic strength of fabric is directly related to its durability and service life during use. Testing the elastic strength of fabric can predict the deformation of fabric after long-term use or multiple washings, so as to ensure that the fabric can maintain its original shape and dimensional stability. The testing of the elastic strength of fabric can also provide textile manufacturers with information about their production process and materials. By comparing the elastic strength of fabrics under different production processes and materials, manufacturers can find the best production plan and improve product quality and production efficiency. At the same time, understanding the changing law of fabric elastic strength can also help manufacturers better control production costs and improve market competitiveness.

[0003] When testing fabrics, the elastic strength testing device needs to place the fabric to be tested on a positioning structure, impact the center of the elastic fabric through the impact structure, and perform multiple tests with different weights to observe whether the fabric cannot return to its original state after being impacted, so as to know the degree of elastic force. However, during the test, since the fabric needs to be positioned, the multi-point positioning operation process is relatively cumbersome, and the edge of the fabric cannot be quickly positioned completely, which affects the efficiency of the fabric test.

[0004] After searching, the Chinese patent with publication number CN 217304652 U discloses an elastic fabric elastic strength detection device, which relates to the field of elastic fabric detection technology, and includes a base, a support frame is fixedly installed on the left side of the upper surface of the base, and a fixed cylinder is fixedly installed on the right side of the upper surface of the base. The elastic fabric elastic strength detection device pulls the slide to move to the left side by retracting the telescopic end of the electric push rod, pulls the card block to disengage from the card slot, and the sinker falls downward under the guidance of the guide cylinder. The impact column at the bottom of the sinker performs an impact treatment on the fabric body, and after the impact, the sinker is moved upward by the dial plate, so that the top of the connecting column interferes with the block, and the block is forced to move to the left, compressing the spring, and continuously moving upward. When the block is located in the card slot position, it is pushed into the inside of the card slot by the reset force of the spring to interfere with the sinker's descent, and the fabric body is taken out, and whether the fabric body is deformed or damaged is observed, and the elastic fabric is detected.

[0039] The staff places the fabric to be tested on top of the inner cylinder 203 and directly above the rubber ring 205. After completion, the outer cylinder 201 is connected to the inner cylinder 203 with a thread, driving the lower gear ring 204 above the outer cylinder 201 to contact the fabric, so as to position the fabric between the outer cylinder 201 and the inner cylinder 203.

[0040] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the impact assembly 5 includes a positioning rod 501 movably installed below the auxiliary cylinder 7, and two elastic arc rods 506 are symmetrically and evenly distributed and fixedly connected above the positioning rod 501, and an outer tooth plate 507 is fixedly connected above the elastic arc rod 506, and an inner tooth arc plate 508 is movably connected to the outer wall of the outer tooth plate 507. Under the elastic support of the elastic arc rod 506, the outer tooth plate 507 passes through the arc groove 511 and the inner tooth arc plate 508. Under the elastic cooperation, the two outer tooth plates 507 bend toward the middle and continue to push upward to be spliced ​​with the inner tooth arc plate 508. Driven by the rotation of the protective window frame 603, the inner tooth arc plate 508 gradually separates from the outer tooth plate 507, so that its positioning rod 501 limits it, and it falls freely downward, thereby performing an impact test on the elasticity of the fabric. A torsion assembly 6 is provided above the inner tooth arc plate 508, and an auxiliary plate 510 is fixedly connected to the middle of the inner wall of the auxiliary cylinder 7. The surface of the auxiliary plate 510 Two arc grooves 511 are symmetrically and evenly distributed, and the elastic arc rod 506 passes through the arc groove 511 in the auxiliary plate 510, and the elastic arc rod 506 is guided by the arc groove 511, so that the outer tooth plate 507 connected above the elastic arc rod 506 contacts the inner tooth arc plate 508 above, and the positioning rod 501 is locked in the auxiliary cylinder 7. An extension rod 502 is fixedly connected below the positioning rod 501, and the amount of weight disk 505 carried by the extension rod 502 can be increased. The lower end of the extension rod 502 is fixedly connected to an impact head 504, and the impact head 504 contacts the surface of the fabric to make it bear a certain impact force to test its elasticity. The outer wall of the impact head 504 is fixedly connected to a support plate 503, and a weight disk 505 is arranged above the support plate 503. The weight disk 505 used for weight adjustment is supported by the support plate 503, so as to provide sufficient weight for the impact process;

[0041] After the staff positions the auxiliary cylinder 7 with the impact head 504 facing downward and adjusts the length between the square rod 4 and the square cylinder 3 to the specified length, they place the corresponding weight plate 505 above the support plate 503 connected to the extension rod 502 according to the required impact force. After completion, the motor 509 is started to drive the protective window frame 603 to rotate, and then the inner tooth arc plate 508 installed thereunder is driven to rotate, so that the inner tooth arc plate 508 is disengaged from the meshed outer tooth plate 507. At this time, driven by gravity, the impact head 504 falls downward to test the elasticity of the fabric, so that the height and gravity of the impact structure can be adjusted according to the requirements of the elasticity test process, and comparative tests can be performed in a controlled variable manner to improve the accuracy of the elasticity test.

[0042] like Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, the torsion assembly 6 includes a protective window frame 603 fixedly mounted above the two inner tooth arc plates 508, through which the airflow generated by the inclined plate 605 during the rotation process is guided and released to protect the air permeability test. An auxiliary ring frame 606 is fixedly connected below the protective window frame 603, and a plurality of inclined plates 605 are fixedly connected to the inner wall of the auxiliary ring frame 606 in a circumferentially uniformly distributed manner. During the torsion tensile test, the plurality of inclined plates 605 can support the conical rod 604 and generate airflow during the rapid rotation process to assist the air permeability test. The middle of the upper surface of the protective window frame 603 is fixedly connected with a conical rod 604. The protrusion of the conical rod 604 allows it to contact the surface of the fabric during the torsion test and rotate to achieve the torsion tensile test. The middle of the lower part of the protective window frame 603 is fixedly connected with a motor 509. The lower part of the motor 509 is fixedly mounted on the upper surface of the auxiliary plate 510. The auxiliary plate 510 provides stable support for the motor 509 during the working process. The upper part of the auxiliary ring frame 606 is movably connected with an inner ring block 601. The outer wall of the inner ring block 601 is fixedly mounted on the inner wall of the auxiliary cylinder 7. 01 cooperates with the auxiliary ring frame 606 to limit the protective window frame 603 to prevent it from detaching from the auxiliary tube 7 and affecting its test process. A cone protection tube 602 is fixedly connected to the top of the auxiliary tube 7. The outer wall of the cone protection tube 602 is movably connected to the inner wall of the transparent tube 202. During the elasticity test, the cone protection tube 602 is used to protect the outer periphery of the fabric to prevent the impact head 504 from being rebounded and causing injuries to personnel. During the air permeability test and the torsion tensile test, the cone protection tube 602 is in contact with the transparent tube 202, providing a relatively closed space for its test process to prevent external factors from affecting it. The test data is affected. A first sensor 607 is provided at the bottom of the inner wall of the inner cylinder 203, and a second sensor 608 is provided on one side of the upper surface of the auxiliary cylinder 7. During the air permeability test, the auxiliary cylinder 7 is inverted on the top of the fabric, and the airflow generated by the rotation of the inclined plate 605 passes through the fabric to be tested and enters the inner cylinder 203. At this time, the second sensor 608 above the auxiliary cylinder 7 can detect the generated airflow, and the airflow passing through the fabric is detected by the first sensor 607 in the inner cylinder 203. The two sets of data are compared to obtain the air permeability test data of the fabric to be tested.

[0043] The staff turns the auxiliary tube 7 upside down and inserts the square rod 4 into the square tube 3, so that it controls the conical rod 604 to contact the fabric, and the transparent tube 202 and the conical protective tube 602 are connected to each other. After the connection, a relatively closed environment is provided for the fabric testing process. After completion, the motor 509 is started to drive the protective window frame 603 above to rotate, and then the conical rod 604 installed above it is driven to rotate, providing a torsional force for the fabric in contact with it, so that the fabric can be subjected to a torsional tensile test, thereby improving the convenience of fabric testing.

[0044] Working principle: After placing the whole structure in a suitable position, place the fabric to be tested on top of the inner cylinder 203 and directly above the rubber ring 205. After completion, the outer cylinder 201 is connected to the inner cylinder 203 by a thread, driving the lower gear ring 204 on the outer cylinder 201 to contact the fabric, so as to position the fabric between the outer cylinder 201 and the inner cylinder 203;

[0045] Elasticity test: Position the auxiliary tube 7 with the impact head 504 facing downward, and adjust the length between the square rod 4 and the square tube 3 to the specified length, align the pin hole 8 with the pin hole 9, insert the positioning pin 10 to lock its height, and place the corresponding weight plate 505 above the support plate 503 connected to the extension rod 502 according to the required impact force. After completion, start the motor 509 to drive the protective window frame 603 to rotate, and then drive the inner tooth arc plate 508 installed below it to rotate with it, so that the inner tooth arc plate 508 is separated from the meshed outer tooth plate 507. At this time, driven by gravity, the impact head 504 falls downward to test the elasticity of the fabric. After completion, the extension rod 502 picks up the impact head 504, and the elastic arc rod 506 passes through the arc groove 511 in the auxiliary plate 510 along the hole below the auxiliary tube 7, and the inner tooth arc plate 508 located above is meshed with the outer tooth plate 507 to lock the height of the impact head 504.

[0047] Air permeability test: still put the auxiliary tube 7 upside down, and insert the square rod 4 into the square tube 3, control the conical rod 604 to have a certain distance from the fabric, after the adjustment is completed, pass the positioning pin 10 through the pin hole 8 and the pin hole 9 to position it, at this time the transparent tube 202 is still sleeved on the cone protection tube 602, after sleeved, it provides a corresponding closed environment for the fabric testing process, after completion, start the motor 509 to drive the protective window frame 603 to rotate, due to the auxiliary ring frame 606 under the protective window frame 603, the inclined plate 605 connected to its inner wall follows the rotation, generating a downward airflow through the fabric, at this time the second sensor 608 in the auxiliary tube 7 and the first sensor 607 in the inner tube 203 simultaneously test the felt airflow to compare their air permeability.
