Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, specifically to an elasticity testing device for high-elasticity thermal insulation textile fabrics. Background Technology

[0002] Fabric is the material used to make clothing. As one of the three essential elements of clothing, fabric not only interprets the style and characteristics of clothing, but also directly affects the color and shape of clothing. After the fabric is produced, its elasticity needs to be tested in order to classify fabrics with different elasticities.

[0003] A prior art fabric elasticity testing device, such as the utility model patent document with authorization announcement number "CN218412026U" and patent name "An Elasticity Testing Device for Woven Fabric", discloses a fabric elasticity testing device, including a testing platform. The testing platform is equipped with a testing component for testing fabric elasticity. The testing component includes a clamping component for clamping the fabric and a motion component for performing elastic stretching motion.

[0004] The aforementioned patent document describes how the fabric end is clamped using a first support block and a first clamping block, and the fabric is secured between the first support block and the first clamping block using bolts. This method requires the operator to rotate the bolts. If too much force is applied when tightening the bolts, exceeding the bolt's strength rating, it may cause stripping between the bolt and the thread, requiring the operator to replace the first support block. This makes it inconvenient for the operator to test the fabric's elasticity. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an elasticity testing device for high-elasticity thermal insulation textile fabrics. This addresses the problem mentioned in the background section where existing fabric elasticity testing devices use a first support block and a first clamping block to hold the fabric end, securing it between the first support block and the first clamping block with bolts. This method requires the operator to rotate the bolts, and if excessive force is applied during tightening, exceeding the bolt's strength rating, it may cause stripping between the bolt and the threads, necessitating the replacement of the first support block. This makes it inconvenient for the operator to test the fabric elasticity.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] An elasticity testing device for high-elasticity thermal insulation textile fabric includes a worktable with a guide rail fixedly mounted on it. Two sliders that can move away from or close to each other are slidably mounted inside the guide rail. Each slider has a fixed block fixedly mounted on it. A first connecting rod and a second connecting rod are rotatably mounted on each fixed block. An mounting block is also provided on the fixed block. The other ends of the first and second connecting rods are rotatably connected to the mounting block. A clamping block is provided on the second connecting rod for clamping the fabric on the fixed block.

[0008] Working principle:

[0009] First, the operator takes a 10 cm x 5 cm test sample cloth. Then, the operator places both ends of the test sample cloth between two clamping blocks and two fixing blocks. The operator then drives the mounting block, which moves the first connecting rod and the second connecting rod to rotate around the axis on the fixing block. The clamping block on the second connecting rod gradually approaches and abuts against the test sample cloth on the fixing block. After the test sample cloth is clamped, the operator moves the two sliders away from each other at a speed of 20 mm / min or 100 mm / min until the set force value is reached, and then measures the corresponding elongation.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] Both the first and second connecting rods are rotatably connected to the mounting block and the fixing block, forming a four-bar linkage mechanism. The linkage mechanism allows the clamping block to fit the fabric, which is suitable for clamping samples with complex shapes. The slider can slide bidirectionally within the guide rail, allowing for free adjustment of the distance between the two fixing blocks. Attached Figure Description

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0015] Example:

[0016] like Figure 1As shown, an elasticity testing device for a high-elasticity thermal insulation textile fabric includes a worktable 1, a guide rail 2 fixedly mounted on the worktable 1, two sliders 3 slidably mounted inside the guide rail 2 that can move away from or towards each other, a bidirectional screw 14 rotatably mounted inside the guide rail 2, and the two sliders 3 respectively screwed onto the two threaded sections of the bidirectional screw 14. A motor 15 is mounted on the worktable 1 to drive the bidirectional screw 14. After the motor 15 is started, it drives the bidirectional screw 14 to rotate inside the guide rail 2. Since the two threaded sections of the bidirectional screw 14 rotate in opposite directions, the two sliders 3 screwed onto it slide synchronously in opposite directions along the guide rail 2 under the action of the threads, realizing the movement of moving away from or towards each other.

[0017] like Figure 1 As shown, both fixed blocks 4 are equipped with clamping components for initial clamping of the fabric. The clamping components include a fixed rod 11, a sliding block 12, and a spring 13. The fixed rod 11 is fixed on the fixed block 4, the sliding block 12 is slidably mounted on the fixed rod 11, and the two ends of the spring 13 are respectively fixed on the fixed rod 11 and the sliding block 12. The sliding block 12 is pulled upward to slide along the fixed rod 11 and compress the spring 13. Then the end of the fabric is placed between the fixed block 4 and the sliding block 12. After that, the spring 13 rebounds and pushes the sliding block 12 downward, clamping the two ends of the fabric together with the fixed block 4 to achieve initial fixation.

[0018] like Figure 1 As shown, each of the two sliders 3 is fixed with a fixing block 4. Each fixing block 4 is rotatably equipped with a first connecting rod 5 and a second connecting rod 6. Each fixing block 4 is also equipped with an mounting block 7. The other ends of the first connecting rod 5 and the second connecting rod 6 are rotatably connected to the mounting block 7. The second connecting rod 6 is equipped with a clamping block 8, which is used to clamp the fabric on the fixing block 4. Each of the two fixing blocks 4 is rotatably equipped with a pneumatic rod 9. The telescopic ends of the two pneumatic rods 9 are respectively rotatably mounted on the two mounting blocks 7. When the telescopic ends of the pneumatic rods 9 retract, they push the mounting blocks 7 downward. The downward movement of the mounting blocks 7 causes the first connecting rod 5 and the second connecting rod 6 to rotate, forcing the clamping block 8 to move and press against the fabric on the surface of the fixing block 4.

[0019] like Figure 1 As shown, both the fixing block 4 and the clamping block 8 are fixed with rubber blocks 10 on one side for clamping the fabric. The rubber blocks 10 provide a contact surface with a high coefficient of friction to prevent the fabric from slipping.

[0020] Working principle:

[0021] The two ends of the fabric to be tested are placed on the surfaces of the two fixed blocks 4 respectively. The operator pulls the sliding block 12 to slide it along the fixed rod 11 and compress the spring 13. The rebound force of the spring 13 drives the sliding block 12 and the fixed block 4 to work together to complete the initial clamping of the fabric. Then, the telescopic end of the air rod 9 retracts, pushing the mounting block 7 down and driving the first connecting rod 5 and the second connecting rod 6 to rotate, causing the clamping block 8 to press against the surface of the fixed block 4. During this process, the rubber block 10 on the surface of the clamping block 8 and the fixed block 4 is tightly pressed against the fabric to form a flexible locking force to prevent the fabric from slipping or being damaged. After that, the operator starts the motor 15 to drive the bidirectional screw 14 to rotate. Through the reverse thread, the sliders 3 on both sides move away from the guide rail 2 synchronously, so that the fixed block 4 drives the two ends of the fabric to separate smoothly, realizing the stretching operation of the fabric. During the stretching process, the motor 15 precisely controls the movement distance of the slider 3 and records the fabric deformation and rebound performance in real time to complete the elasticity test.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
