Description

Technical Field

[0001] The present invention relates to the technical field of artificial turf detection, and particularly to a device for detecting the tensile strength of artificial turf fiber filaments. Background Art

[0002] At present, with the rapid development of the artificial turf industry, artificial turf is widely used in various sports stadiums, municipal greening, family courtyards and other scenarios. Among them, as the core component of artificial turf, the tensile strength of fiber filaments is directly related to the wear resistance, anti-trampling ability and overall service life of the turf, and is a key indicator for measuring the quality of artificial turf. However, there are many problems to be solved urgently in the existing devices for detecting the tensile strength of artificial turf fiber filaments on the market.

[0003] On the one hand, traditional detection devices have a single function and can only detect the tensile strength of fiber filaments at normal temperature. They cannot simulate the influence of different temperature environments on the performance of fiber filaments. In actual use, artificial turf is exposed to the outdoors for a long time, and changes in environmental temperature may cause changes in the material properties of fiber filaments, affecting their tensile strength. However, the existing devices lack a temperature adjustment function, making the detection results unable to truly reflect the actual performance of fiber filaments in complex environments and difficult to meet the comprehensive requirements of product quality evaluation.

[0004] On the other hand, the existing detection devices are inefficient when conducting multiple groups of control experiments. When it is necessary to compare and detect fiber filaments of different batches and different process treatments, or to repeat the detection to verify the data accuracy, traditional devices often need to reinstall and fix the fiber filaments. The whole process is cumbersome, consuming a lot of time and manpower. The cumbersome repeated operations not only reduce the detection efficiency, but also increase the risk of human operation errors, resulting in a decrease in the reliability of the detection results and unable to meet the needs of high-efficiency quality inspection in large-scale production of enterprises.

[0005] In summary, it has become an urgent need to develop a device for detecting the tensile strength of artificial turf fiber filaments that can achieve detection in multiple temperature environments, efficiently complete multiple groups of control experiments, and have stable and reliable detection performance, so as to improve the quality of artificial turf products and promote the technological progress of the industry.

This design breaks through the limitation that traditional devices can only detect at room temperature, can comprehensively evaluate the tensile properties of the fiber wire in different temperature environments, makes the detection results more in line with the actual application scenario, and greatly improves the comprehensiveness and practicality of the detection.

[0022] For the needs of multiple sets of control experiments, the device is designed with an efficient and convenient operation process. After the fiber filament is broken, only the locking of the wire locking mechanism needs to be released, and pulling the fiber filament can drive the rotating roller to release a new detection length. After fixing again, the next set of experiments can be quickly carried out. Compared with the cumbersome process of reinstalling and fixing the fiber filament in traditional devices, this mode greatly saves time and manpower, significantly improves the detection efficiency, reduces human operation errors, and provides strong support for quality inspection and process optimization in large-scale production.

Detailed implementation manners

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] As Figures 1 - 10 shown, a tensile strength detection device for artificial turf fibers provided by an embodiment of the present invention includes a detection table 101. A support rod 102 is fixedly installed on the upper surface of the detection table 101, and a support plate 103 is fixedly installed at the top end of the support rod 102. Symmetrically distributed vertical plates 105 are fixedly installed on the upper surface of the support plate 103, and a rotating shaft 106 is rotatably installed between the vertical plates 105. A rotating roller 107 is fixedly installed on the outer wall of the rotating shaft 106, and a rubber sleeve 108 is fixedly sleeved on the outer wall of the rotating roller 107. A through hole 104 is further opened on the outer wall of the support plate 103, and the through hole 104 is located directly below the rotating roller 107. A first telescopic cylinder 109 is also fixedly installed on the upper surface of the support plate 103, and a lifting frame 110 is fixedly installed at the telescopic end of the first telescopic cylinder 109. It further includes: a wire locking mechanism, which is arranged above the support plate 103 and is used to lock the fiber wire wound around the outer side of the rotating roller 107 to the outer side of the rotating roller 107; a wire drawing mechanism, which is arranged in the lifting frame 110 and is used to clamp and fix one end of the fiber wire and lift and lower together with the lifting frame 110 to realize the tensile test of the fiber wire; a heating mechanism, which is arranged below the lifting frame 110 and is used to heat the fiber wire to be detected.

[0036] The fiber filament to be detected can pass through the through hole 104 on the support plate 103 and wind around the surface of the rubber sleeve 108 outside the rotating roller 107 for multiple turns. Then, the fiber filament wound around the surface of the rubber sleeve 108 outside the rotating roller 107 can be held against by the wire locking mechanism, and at the same time, the position of the rotating roller 107 can be fixed, thereby realizing the locking of the fiber filament. Then, the end of the fiber filament is fixed in the wire drawing mechanism. At this time, by driving the lifting frame 110 to move upward through the first telescopic cylinder 109, the wire drawing mechanism can pull the fiber filament between the wire drawing mechanism and the rotating roller 107, and detect the pulling force, so as to realize the tensile strength detection operation of the fiber filament. And before pulling the fiber filament, the fiber filament can be heated by the heating mechanism, and then the tensile strength of the fiber filament under different temperature environments can be detected, making the use more flexible. Further, when the fiber filament is broken and multiple groups of control experiments need to be carried out at the same time, the locking of the fiber filament outside the rotating roller 107 by the wire locking mechanism can be released first, and then the broken fiber filament can be directly pulled. At this time, the rotating roller 107 will rotate along with it. Until the fiber filament is pulled to an appropriate length, the rotating roller 107 and the fiber filament can be locked again by the wire locking mechanism, and then the end of the broken fiber filament is continuously fixed in the wire drawing mechanism, and the control experiment of the fiber filament stretching can be carried out again, effectively realizing that the detection efficiency of the fiber filament can be greatly improved when multiple groups of control experiments of the fiber filament are carried out, and the use effect is better.

[0037] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the wire locking mechanism includes a fixing plate 201 fixedly arranged on the upper surface of the support plate 103, and an installation hole is opened on the outer wall of the fixing plate 201. A second telescopic cylinder 202 is fixedly installed in the installation hole, and a clamping plate 203 is fixedly installed at the telescopic end of the second telescopic cylinder 202. A rubber strip 204 is fixedly installed on the inner wall of the clamping plate 203 for holding against the fiber filament wound around the outside of the rubber sleeve 108. A locking component is also arranged outside the clamping plate 203 for locking the position of the rotating roller 107 when the clamping plate 203 approaches the rotating roller 107. When the fiber filament is wound around the outside of the rubber sleeve 108, the clamping plate 203 can be driven to move through the second telescopic cylinder 202. During the moving process, the locking component outside the clamping plate 203 will first lock the rotating roller 107, and then as the clamping plate 203 continues to move, the rubber sleeve 108 in the clamping plate 203 will closely fit with the rubber sleeve 108 outside the rotating roller 107, so that the fiber filament is clamped and locked between the rubber sleeve 108 and the rubber strip 204, achieving the purpose of locking the fiber filament.

[0038] As an embodiment of the present invention, please refer to Figure 2 , Figure 3 and Figure 4, the locking assembly includes locking rods 302 fixedly arranged on both sides of the clamping plate 203. Both ends of the rotating shaft 106 are fixedly installed with locking cylinders 301, and the outer wall of the locking cylinder 301 is provided with locking ports 303 that are equidistantly distributed in a circular pattern. The inner walls on both sides of the locking port 303 are parallel to each other, and the inner diameter of the locking port 303 is the same as the outer diameter of the locking rod 302. When the clamping plate 203 moves towards the rotating roller 107, the locking rods 302 on both sides of the clamping plate 203 will insert into the locking ports 303 on the outside of the locking cylinder 301, achieving the purpose of limiting the position of the rotating roller 107. And because the inner walls on both sides of the locking port 303 are parallel to each other, and at the same time the inner diameter of the locking port 303 is the same as the outer diameter of the locking rod 302, when the locking rod 302 inserts into the locking port 303, the locking rod 302 is completely attached to the inner wall of the locking port 303, making the locking position of the locking rod 302 on the locking cylinder 301 more stable, effectively avoiding the influence on the detection caused by the shaking of the rotating roller 107, and the use effect is better.

[0039] As an embodiment of the present invention, please refer to Figure 4 , the outer wall of the locking cylinder 301 is also fixedly installed with dislocation blocking strips 304 that are equidistantly distributed in a circular pattern. The cross-section of the dislocation blocking strip 304 is semicircular, and the dislocation blocking strip 304 is located between adjacent locking ports 303. The end of the locking rod 302 close to the locking cylinder 301 is arc-shaped. When the locking rod 302 approaches the locking cylinder 301 and the end of the locking rod 302 just aligns with the position between adjacent locking ports 303, the arc-shaped end of the locking rod 302 will contact the dislocation blocking strip 304, prompting the locking cylinder 301 to rotate, so that the locking rod 302 can be smoothly inserted into the locking port 303 to complete the locking operation of the rotating roller 107, and the use effect is better.

[0040] As an embodiment of the present invention, please refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the wire drawing mechanism includes a mounting plate 401 fixedly arranged on the inner wall of the lifting frame 110. The outer wall of the mounting plate 401 is provided with a mounting opening, and a fixed frame 402 is fixedly installed on the lower surface of the mounting plate 401. A wire clamping assembly is movably installed in the mounting opening. The bottom inner wall of the fixed frame 402 is fixedly installed with pressure sensors 403 that are equidistantly distributed in a circular pattern, and the wire clamping assembly is located above the pressure sensors 403. The end of the fiber wire can be fixed in the wire clamping assembly. The telescopic cylinder one 109 can drive the fixed frame 402 to move upward. At this time, the fiber wire will generate a downward pulling force on the wire clamping assembly, and the wire clamping assembly will press down the pressure sensors 403 in the fixed frame 402, achieving the purpose of detecting the pulling force. The maximum pressure value detected by the pressure sensors 403 can be used to judge the tensile strength of the fiber wire, and the use is very convenient.

[0041] As an embodiment of the present invention, please refer toFigure 7 , Figure 8 and Figure 9 , the wire clamping assembly includes a movable cover 501 movably installed in the fixed frame 402, and the movable cover 501 is located above the pressure sensor 403. A hopper 503 is movably installed in the movable cover 501, and a connecting rod 506 is fixedly installed on the upper surface of the hopper 503. The connecting rod 506 passes through the mounting opening, and a lifting block 504 is fixedly installed at the top end of the connecting rod 506. A positioning hole is formed in the outer wall of the lifting block 504, and an electric telescopic rod 505 is fixedly installed in the positioning hole. The telescopic end of the electric telescopic rod 505 is connected to the upper surface of the movable cover 501. A rubber ring gasket 502 is fixedly installed on the inner wall of the movable cover 501, and the rubber ring gasket 502 is located between the movable cover 501 and the hopper 503. A wire winding assembly is further provided outside the hopper 503 for winding the end of the fiber wire around the outside of the hopper 503. When the end of the fiber wire needs to be fixed, the electric telescopic rod 505 can be contracted to drive the lifting block 504 to move downward. The lifting block 504 can drive the hopper 503 to move downward together through the connecting rod 506, so that the hopper 503 is moved out of the movable cover 501. At this time, the end of the fiber wire can be passed through the hopper 503, and the fiber wire can be wound around the outside of the hopper 503 by means of the wire winding assembly. Then, the hopper 503 is driven to move back into the movable cover 501 by the telescopic movement of the electric telescopic rod 505, so that the fiber wire outside the hopper 503 can be clamped between the rubber ring gasket 502 on the inner wall of the movable cover 501 and the hopper 503, achieving the purpose of locking the end of the fiber wire in the movable cover 501. When the fiber wire is pulled, a downward pulling force will be applied to the movable cover 501, prompting the movable cover 501 to press down the pressure sensor 403 in the fixed frame 402, thereby completing the tensile test of the fiber wire, which is very convenient to use.

[0042] As an embodiment of the present invention, please refer to Figure 7 , Figure 8 and Figure 9, the wire winding assembly includes an upper winding rod 601 fixedly arranged in a ring shape at equal intervals at the top end of the inverted hopper 503. At the bottom end of the inverted hopper 503, lower winding rods 602 are fixedly installed at equal intervals, and the upper winding rod 601 and the lower winding rod 602 are arranged in a staggered manner. At the bottom end of the inverted hopper 503, symmetrically distributed rubber blocks 603 are also fixedly installed, and the rubber blocks 603 are in contact with each other. When fixing the fiber wire, when the end of the fiber wire passes out from the top end of the inverted hopper 503, it can first be wound around the upper winding rod 601 and pulled downward along the outer side of the inverted hopper 503, and then wound around the lower winding rod 602 at the bottom end of the inverted hopper 503 again, and then pulled upward along the outer side of the inverted hopper 503, and at the same time wound around another group of upper winding rods 601 at the top end of the inverted hopper 503. This cycle continues until the end of the fiber wire is clamped between adjacent rubber blocks 603. At this time, the fiber wire can be wound around the outer side of the inverted hopper 503, which is convenient for the subsequent fiber wire to be clamped between the movable cover 501 and the inverted hopper 503, and the use effect is better.

[0043] As an embodiment of the present invention, please refer to Figure 6 , the heating mechanism includes mounting brackets 701 symmetrically and fixedly installed on the lower surface of the mounting plate 401. Fixing holes are formed in the side walls of the mounting brackets 701, and electric telescopic rods II 702 are fixedly installed in the fixing holes. The telescopic ends of the electric telescopic rods II 702 are fixedly installed with clamping plates 703, and electric heating plates 704 are fixedly installed on the outer walls of the clamping plates 703. When it is necessary to heat the fiber wire, the electric heating plate 704 can be raised to the set temperature, and then the clamping plate 703 can be driven to move by the electric telescopic rod II 702, so that the fiber wire can be clamped between the electric heating plates 704, playing a role in heating the fiber wire, facilitating the detection of the tensile strength of the fiber wire at different temperatures, and the use effect is better.
