[0002] A tensile testing machine, also known as a universal testing machine, is a mechanically applied testing machine used to perform static load, tensile, compression, bending, shearing, tearing, and peeling tests on various materials. Polyester fiber, commonly known as "polyester," is a synthetic fiber made from organic dicarboxylic acids and diols through chemical polycondensation. It belongs to the category of polymer compounds. After production, polyester fiber undergoes an elastic tensile test to check its quality.

[0003] A search revealed a patent with application number CN202420784285.1, which discloses a polyester fiber elasticity performance testing device. This device uses a tensile sensor to detect the elasticity of polyester fibers. However, this method can only achieve vertical parallel stretching during the testing process. Polyester fibers can take on different forms during use, such as twisting at a certain angle. To obtain test data of polyester fibers under different twisting conditions, a new type of polyester fiber resilience performance testing device is needed. Utility Model Content

A U-shaped placement platform is fixedly mounted on the side of the tension sensor and the rotating disk that are close to each other, and a clamping assembly is provided on the U-shaped placement platform.

[0007] Preferably, the tensioning assembly includes a telescopic cylinder fixedly installed on the top of the test frame, the output end of the telescopic cylinder is connected to a connecting plate, and a tension sensor is installed at the bottom of the connecting plate.

[0008] Preferably, the rotary drive assembly includes a rotary groove formed on the test frame, a rotary column rotatably mounted on the bottom inner wall of the rotary groove, and the bottom of the rotary disk being fixedly connected to the top of the rotary column.

[0010] Preferably, the top of the test frame is provided with an angle offset indicator scale, and an angle offset indicator block is fixedly installed on the outside of the rotating disk, the angle offset indicator block being adapted to the angle offset indicator scale.

[0011] Preferably, the clamping assembly includes a compression cylinder fixedly installed on the side of the U-shaped placement platform, and the output end of the compression cylinder is connected to a clamping plate, which is located between the U-shaped placement platforms.

[0012] Preferably, anti-slip pads are fixedly installed on one inner wall of both the pressing plate and the U-shaped placement platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the polyester fiber resilience performance testing device is equipped with a clamping component that can clamp the two ends of the polyester fiber, which facilitates subsequent tensile testing; the tensioning component moves the upper U-shaped placement platform upward, and the elastic tensile data of the polyester fiber can be known through the sensing value on the tension sensor, thus realizing the detection of elastic tensile strength.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Refer to Figure 1-4 A polyester fiber resilience testing device includes a test frame 1, a rotating disk 4 mounted on the test frame 1 via a rotation drive assembly, a tension sensor 16 mounted on the top of the test frame 1 via a tension assembly, and U-shaped placement platforms 5 fixedly mounted on the sides of the tension sensor 16 and the rotating disk 4 respectively. A clamping assembly is provided on the U-shaped placement platform 5, including a compression cylinder 6 fixedly mounted on the side of the U-shaped placement platform 5. A pressure plate 7 is connected to the output end of the compression cylinder 6 and is located between the U-shaped placement platforms 5. Anti-slip pads 8 are fixedly mounted on the inner walls of both the pressure plate 7 and one side of the U-shaped placement platform 5. The ends of the polyester fiber to be tested are respectively placed within the two U-shaped placement platforms 5. The compression cylinder 6 on the clamping assembly operates, driving the pressure plate 7 to move. After the pressure plate 7 moves, it can cooperate with one side of the U-shaped placement platform 5 to clamp the placed polyester fiber. The anti-slip pads 8 provide excellent anti-slip properties, resulting in a more stable clamping effect.

[0022] Furthermore, the tensioning assembly includes a telescopic cylinder 14 fixedly installed on the top of the test frame 1. The output end of the telescopic cylinder 14 is connected to a connecting plate 15. A tension sensor 16 is installed at the bottom of the connecting plate 15. After the polyester fiber is clamped, the telescopic cylinder 14 on the tensioning assembly is started to move, causing the connecting plate 15 to move upward, thereby causing the U-shaped placement platform 5 above to move upward. The elastic tensile data of the polyester fiber can be known through the sensing value on the tension sensor 16.

[0023] Furthermore, the rotary drive assembly includes a rotary groove 2 formed on the test frame 1, a rotary column 3 rotatably mounted on the bottom inner wall of the rotary groove 2, a rotary disk 4 fixedly connected to the top of the rotary column 3, a stepper motor 9 fixedly mounted on the bottom inner wall of the rotary groove 2, a drive gear 10 connected to the output end of the stepper motor 9, a driven gear 11 fixedly sleeved on the rotary column 3, the drive gear 10 and the driven gear 11 meshing, an angle offset indicator scale 13 is formed on the top of the test frame 1, an angle offset indicator block 12 is fixedly mounted on the outer side of the rotary disk 4, the angle offset indicator block 12 is adapted to the angle offset indicator scale 13, when it is necessary to adjust the polyester fiber... When performing a torsion test, the stepper motor 9 on the rotary drive assembly is started, driving the drive gear 10 to rotate, which in turn drives the driven gear 11 to rotate. The rotating column 3 will rotate, and the rotating disk 4 will follow suit, causing the lower U-shaped placement platform 5 to rotate while the upper U-shaped placement platform 5 remains stationary. This causes the clamped polyester fiber to twist. The angle offset indicator block 12 can determine the angle of twist based on the value of the angle offset indicator scale 13. By rotating the rotating disk 4, the elasticity data of polyester fibers under different torsion can be detected, thus obtaining the elasticity data of polyester fibers under different conditions, making the detection more accurate.

[0024] In use: After production, polyester fibers need to undergo elasticity testing. The two ends of the polyester fiber to be tested are placed in two U-shaped placement platforms 5. The compression cylinder 6 operates, and the pressing plate 7 moves to clamp the placed polyester fiber. After clamping, the telescopic cylinder 14 is activated. The elastic tensile data of the polyester fiber can be obtained through the sensing value on the tension sensor 16. When a torsion test is required, the stepper motor 9 is activated, driving the drive gear 10 to rotate, which in turn drives the rotating disk 4 to rotate. This causes the lower U-shaped placement platform 5 to rotate while the upper U-shaped placement platform 5 remains stationary, resulting in the clamped polyester fiber twisting. Through the rotation of the rotating disk 4, the elasticity data of polyester fibers with different torsions can be detected, thus obtaining elasticity data of polyester fibers under different conditions. The testing is more accurate and convenient to use.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
