Description

Technical Field

[0001] The invention relates to the technical field of tensile strength detection, and in particular to a fiber tensile strength detection device and method based on artificial turf fiber yarn production. Background Art

[0002] With the continuous improvement of living standards in modern society and the vigorous development of the sports field, the artificial turf market has expanded significantly. This trend is mainly attributed to the widespread application of artificial turf in many fields, especially in sports venues such as football fields, tennis courts, and golf courses. The core component of artificial turf is fiber filaments. The main raw materials of fiber filaments are synthetic fibers such as polypropylene and polyethylene. These synthetic fiber materials are made into grass filaments with specific shapes and sizes through melting, extrusion, molding and cooling process steps. They can simulate the appearance and touch of real lawns and provide users with a comfortable and natural experience.

[0003] A glass fiber finished product tensile strength detection device disclosed in the patent application with reference publication number CN117890192A can detect multiple glass fiber cloths at the same time by setting up multiple pulling mechanisms, so as to have a more comprehensive understanding of the performance of glass fiber cloths at different lengths, and then help to discover potential problems, performance differences and optimal application scenarios of glass fiber cloths at different lengths. As the glass fiber cloth is tensioned and the pulling force increases, the pressing member increases the contact force between the glass fiber cloth and the pressure rod, that is, the greater the pushing force on the pressing plate. As the pulling force on the glass fiber cloth increases, the pressing force of the pressing plate on the glass fiber cloth also increases to ensure the stability of the fixed end of the glass fiber cloth. The actuator drives the shaft column through the connecting rod by pushing the limit plate, and the pressure rod clamps the cloth through the cooperation of the track groove and the guide column.

Beneficial Effects

[0023] The present invention provides a fiber tensile strength detection device and method based on artificial turf fiber production. Compared with the prior art, it has the following beneficial effects:

[0054] The embodiment of the present invention further provides a method for detecting the tensile strength of fibers produced based on artificial turf fibers, using a device for detecting the tensile strength of fibers produced based on artificial turf fibers. The specific method includes the following steps:

[0055] Step 1: Use a marker to draw two marking lines on the surface of the artificial turf fiber to be tested, and perform a tensile strength test on the portion of the artificial turf fiber between the two marking lines, wherein the length of the artificial turf fiber between the two marking lines is a known quantity, then fasten one end of the artificial turf fiber to the hook ring of the tensile gauge 4, pull the other end thereof through the limiting mechanism 6 on the right, that is, through the side opening 62, and pass through the gap between the right side of the rubber roller 67 and the inner wall of the transparent containing box 61, then pull out a portion of the length of the artificial turf fiber through the upper opening 68, tighten the artificial turf fiber, and make the initial tension of the artificial turf fiber to the required value by observing the reading on the tensile gauge 4, then screw the screw 65 to move the upper clamping plate 66 downward, cooperate with the lower clamping plate 63, clamp the other end of the artificial turf fiber, and keep the initial tension unchanged, and at the same time make the portion of the artificial turf fiber between the two marking lines between the tensile gauge 4 and the limiting mechanism 6, and the artificial turf fiber passes through two adjacent pulling columns 529;

[0056] Step 2, then start the servo motor 515 to drive the driving rod assembly 526 to rotate, and the slider 5261 always slides between the slide groove 524 and the vertical groove 525. With the rotation of the driving rod assembly 526, the vertical plate 523 and the sliding rod 521 are pushed to move back and forth along the limit frame 512, and the bearing plate assembly 527 and the pulling column 529 move back and forth accordingly. Since the artificial turf fiber runs through the two adjacent pulling columns 529, with the movement and coordination of the two adjacent pulling columns 529, the artificial turf fiber can be stretched forward and backward alternately. Within the set time range, the tensile strength of the artificial turf fiber is tested. After the test, the connection between the artificial turf fiber and the hook ring is loosened, and the screw rod 65 is reversely screwed to move the upper clamping plate 66 upward, and the clamping of the artificial turf fiber by the upper clamping plate 66 and the lower clamping plate 63 is released, wherein the right side wall of the upper clamping plate 66 is in sliding contact with the left side wall of the transparent containing box 61;

[0057] Step 3, then pull the right end of the artificial turf fiber thread upward from the top of the limiting mechanism 6. During the pulling process, the limiting mechanism 6 measures the length of the artificial turf fiber thread between the two marking lines. During the process, since the distance between the outer wall of the rubber roller 67 and the right wall of the inner cavity of the transparent containing box 61 is slightly smaller than the external size of the artificial turf fiber thread, when the artificial turf fiber thread passes through the gap between the right side of the rubber roller 67 and the inner wall of the transparent containing box 61, the artificial turf fiber thread is in close contact with the outer wall of the rubber roller 67. In the process of pulling the artificial turf fiber thread upward, the artificial turf fiber thread is used to measure the length of the artificial turf fiber thread between the two marking lines. The friction between the fiber and the rubber roller 67 drives the rubber roller 67 to rotate, and the counter 69 counts the number of rotations of the rubber roller 67, and calculates the number of rotations of the rubber roller 67 caused by the artificial turf fiber portion between the two marking lines. The counter 69 belongs to the prior art known to those skilled in the art. Since the circumference of the rubber roller 67 is known, the length of the artificial turf fiber between the two marking lines can be obtained by calculating the product of the circumference and the number of rotations. The lengths before and after the detection are compared to obtain the deformation amount, thereby analyzing the tensile strength of the artificial turf fiber.
