DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0040] As introduced in the background, the existing problems in the prior art, in order to solve the above technical problems, the present application provides a spinning tensile test equipment and test method.

[0041] Embodiment one, please refer to Figure 1 Figure 12 A spinning tensile test equipment, comprising a detection equipment base 1, a top of the detection equipment base 1 is provided with an up-down moving seat 2, an inside of the up-down moving seat 2 is provided with a protective cover lifting rod 3, a movable end of the protective cover lifting rod 3 is connected with a detection protective cover 4, an inside of the detection protective cover 4 is provided with an upper fixing mechanism 5, a top of the detection equipment base 1 is provided with a lower mounting seat 6, a top of the lower mounting seat 6 is provided with a lower fixing mechanism 7.

[0042] The detection protective cover 4 is slidably installed in the inside of the up-down moving seat 2 through the protective cover lifting rod 3, an outside of the detection protective cover 4 is attached to the inside of the up-down moving seat 2, the detection protective cover 4 and the lower mounting seat 6 can seal the upper fixing mechanism 5 and the lower fixing mechanism 7.

[0043] The detection protective cover 4 can drive the synchronous upper fixing mechanism 5 to move up and down when moving up and down in the inside of the up-down moving seat 2, the upper fixing mechanism 5 can move up and down in the inside of the detection protective cover 4, the detection protective cover 4 can cover above the lower mounting seat 6 when moving downward, the lower fixing mechanism 7 can store and wind the spinning, the upper fixing mechanism 5 can divide the spinning into multiple strands when moving up and down, the upper fixing mechanism 5 and the lower fixing mechanism 7 can fix the upper and lower ends of the spinning, and the upper fixing mechanism 5 can respectively test the multiple strands of spinning.

[0044] ​During operation, the spun yarn is first installed into the lower fixing mechanism 7. Driven by the protective cover lifting rod 3, the protective cover 4 is checked to cover the lower mounting base 6. Then, the upper fixing mechanism 5 moves downward inside the protective cover 4, inserting itself into the lower fixing mechanism 7. The lower fixing mechanism 7 then guides the yarn through the interiors of both the upper and lower fixing mechanisms 7. After the yarn passes through these mechanisms, the upper fixing mechanism 5 moves upward to separate the yarn into multiple strands. The fixing mechanism 7 is divided into an upper fixing mechanism 5 and a lower fixing mechanism 7, which can fix the upper and lower ends of the spinning. After fixing the two ends of the spinning, the lower fixing mechanism 7 can perform tensile testing on the spinning by stretching one end of the spinning. The lower fixing mechanism 7 can perform tensile testing on multiple strands of spinning at the same time. When fixing the spinning, the spinning can be guided and moved first, and then the upper and lower ends of the spinning can be clamped and fixed. By clamping and fixing the two ends of the spinning and simultaneously performing tensile testing on multiple strands of spinning, not only can the accuracy of the test be improved, but also the deviation of individual cases can be prevented by measuring multiple strands of spinning.

[0045] The second specific embodiment differs from the above embodiments in that, please refer to [link / reference needed]. Figure 1 - Figure 12 The upper fixing mechanism 5 includes an upper mounting plate 51, which is fixedly installed inside the detection protective cover 4. An upper telescopic rod 52 is installed on the outside of the upper mounting plate 51. An upper connecting plate 53 is connected to the movable end of the upper telescopic rod 52. An upper wire block 54 is installed on the outside of the upper connecting plate 53. An upper support plate 55 is installed inside the detection protective cover 4. An upper clamping plate 56 is slidably installed inside the upper support plate 55. An upper connecting rod 57 is connected to the top of the upper clamping plate 56. An upper transmission rod 58 is installed on the top of the upper connecting rod 57. A sliding connecting rod 59 is installed inside the upper clamping plate 56. An upper clamping block 510 is connected to the outside of the sliding connecting rod 59. A buffer spring 511 is connected to the outside of the upper clamping block 510. A tensile testing block 512 is installed inside the upper clamping block 510.

[0046] The movable end of the upper telescopic rod 52 passes through the upper support plate 55 and connects to the upper connecting plate 53;

[0047] The upper telescopic rod 52 can drive the upper connecting plate 53 to move up and down inside the detection protective cover 4. When the upper connecting plate 53 moves up and down inside the detection protective cover 4, it can also contact the upper support plate 55 to drive the upper support plate 55 to move up and down. When the upper support plate 55 moves down, it can insert the upper clamping plate 56 into the lower fixing mechanism 7. When the upper support plate 55 moves up, it can drive the upper clamping plate 56 to stretch the spinning yarn into multiple strands.

[0048] Upper clamping plates 56 are installed on both the front and rear sides of the upper connecting plate 53. The upper clamping plates 56 on both sides of the upper support plate 55 are connected by an upper connecting rod 57. The connection point of the upper connecting rod 57 is connected to the upper mounting plate 51 by an upper transmission rod 58.

[0049] When the upper telescopic rod 52 drives the upper connecting plate 53 to move up and down, it can also disengage the upper connecting plate 53 from the upper support plate 55 to drive the upper support plate 55 to move up and down. When the upper support plate 55 moves upward, the upper transmission rod 58 can drive the connection point of the upper connecting rod 57 to move to both sides. When the connection point of the upper transmission rod 58 and the upper connecting rod 57 moves to both sides, it can drive the upper clamping plate 56 to move to the center of the upper support plate 55. When the upper support plate 55 moves downward, the upper transmission rod 58 can drive the connection point of the upper connecting rod 57 and the upper transmission rod 58 to move to the center of the upper support plate 55. When the connection point of the upper connecting rod 57 and the upper transmission rod 58 moves to the center of the upper support plate 55, it can drive the upper clamping plate 56 to move to the outside of the upper support plate 55.

[0050] Multiple upper clamping blocks 510 are installed on the inner side of the upper clamping plate 56. The outer side of the multiple upper clamping blocks 510 is connected to the upper clamping plate 56 through a buffer spring 511 and a tensile detection block 512. When the upper clamping plate 56 moves inside the upper support plate 55, it can drive the upper clamping blocks 510 to move synchronously. The upper clamping blocks 510 are installed at the notch of the upper wire block 54.

[0051] When the upper clamping plate 56 moves inside the upper support plate 55, it can drive the upper clamping block 510 to clamp the spinning. The buffer spring 511 and sliding connecting rod 59 outside the upper clamping block 510 can adapt to the change in the diameter of the spinning. After the upper clamping block 510 clamps the spinning, the tensile testing block 512 can perform tensile testing on the spinning.

[0052] The top of the upper wire block 54 is an arc-shaped structure. When the upper wire block 54 moves downward, it can be inserted into the interior of the lower fixing mechanism 7. When the upper wire block 54 moves upward, it can stretch the spinning yarn into multiple strands.

[0053] When the multiple upper clamping blocks 510 on the upper clamping plate 56 move to the center of the upper support plate 55, they can clamp and fix the multiple strands of yarn respectively through the multiple tensile testing blocks 512.

[0054] During operation, the upper telescopic rod 52 extends, causing the upper connecting plate 53 to move downwards. As the upper connecting plate 53 moves downwards, it causes the upper guide block 54 to insert into the lower fixing mechanism 7. The lower fixing mechanism 7 then guides the spinning yarn through the interior of the upper guide block 54. After the spinning yarn passes through the upper guide block 54, the upper telescopic rod 52 shortens, causing the upper connecting plate 53 to move upwards. As the upper connecting plate 53 moves upwards, it causes the upper guide block 54 to move upwards, stretching the spinning yarn into multiple strands. During the upward movement of the upper connecting plate 53, after contacting the upper support plate 55, the upper connecting plate 53 continues to move upwards, causing the upper support plate 55 to move upwards synchronously. As the upper support plate 55 moves upwards, it can drive the upper... The connection between the connecting rod 57 and the upper transmission rod 58 moves outward to the upper support plate 55. When the connection between the upper connecting rod 57 and the upper transmission rod 58 moves outward to the upper support plate 55, it can drive the upper clamping plate 56 to move towards the center of the upper support plate 55. When the upper clamping plate 56 moves towards the center of the upper support plate 55, it can drive the upper clamping block 510 to move towards the center of the upper support plate 55. When the upper clamping block 510 moves towards the center of the upper support plate 55, it can drive the tensile testing block 512 to clamp the top of the spinning end. During the process of the upper clamping block 510 clamping the spinning end, the buffer spring 511 and the sliding connecting rod 59 can adapt to the change in the diameter of the spinning end. After the tensile testing block 512 clamps the spinning end, it can perform tensile testing on the spinning end.

[0055] The specific embodiment three differs from the above embodiments in that, please refer to [link / reference needed]. Figure 1 - Figure 12 The lower fixing mechanism 7 includes a spinning mounting base 71 and a spinning winding base 72. Both the spinning mounting base 71 and the spinning winding base 72 are installed on the top of the lower mounting base 6. A lower connecting plate 73 is installed on the top of the lower mounting base 6. A lower guide block 74 is installed on the top of the lower connecting plate 73. A lower spinning clamping block 75 is installed on the top of the lower mounting base 6. The two ends of the lower spinning clamping block 75 are connected by a lower transmission rod 76. A lower telescopic rod 77 is installed on the top of the lower mounting base 6.

[0056] The lower spinning clamping blocks 75 are installed on both sides of the lower connecting plate 73. The lower spinning clamping blocks 75 are connected to each other by the lower transmission rod 76. The rotation point of the lower transmission rod 76 is connected to the movable end of the lower telescopic rod 77.

[0057] When the lower telescopic rod 77 extends or retracts, it can drive the lower spinning clamp 75 to move at the top of the lower mounting base 6 via the lower transmission rod 76. When the lower telescopic rod 77 extends, it can drive the connection between the lower transmission rod 76 and the lower telescopic rod 77 to move towards the center of the lower guide block 74. When the connection between the lower transmission rod 76 and the lower telescopic rod 77 moves towards the center of the lower guide block 74, it can drive the lower spinning clamp 75 to move towards the outside of the lower mounting base 6. When the lower telescopic rod 77 shortens, it can drive the connection between the lower transmission rod 76 and the lower telescopic rod 77 to move towards the edge of the lower guide block 74, which in turn can drive the lower spinning clamp 75 to move towards the center of the lower mounting base 6.

[0058] The lower guide block 74 on the lower connecting plate 73 is complementary to the upper guide block 54 on the upper connecting plate 53. The spinning mounting seat 71 and the spinning take-up seat 72 can guide the spinning yarn through the interior of the lower guide block 74 and the upper guide block 54. When the lower guide block 74 moves upward, it can divide the spinning yarn into multiple strands by cooperating with the upper guide block 54. The lower spinning clamp 75 can fix the spinning yarn that is separated from the lower guide block 74.

[0059] During operation, the spun yarn is first mounted onto the spinning mounting base 71. Then, one end of the yarn is pulled through the upper guide block 54 and the lower guide block 74 and connected to the spinning take-up base 72. Rotating the spinning take-up base 72 then causes the yarn to be wound from the spinning mounting base 71 onto the spinning take-up base 72. As the upper guide block 54 rises, the upper and lower guide blocks 54 can stretch the yarn into multiple strands. After the yarn is divided into multiple strands, the lower telescopic rod 77 shortens, causing the connection between the lower transmission rod 76 and the lower telescopic rod 77 to move towards the edge of the lower guide block 74. When the connection between the transmission rod 76 and the lower telescopic rod 77 moves to the edge of the lower guide block 74, it can drive the lower spinning clamp 75 to move to the center of the lower guide block 74. When the lower spinning clamp 75 moves to the center of the lower guide block 74, it can clamp the spinning yarn. When fixing the spinning yarn, the spinning yarn can be pulled by the spinning mounting seat 71 and the spinning winding seat 72. The spinning yarn is then divided into strands by the arc surface on the upper guide block 54 and the arc surface on the lower guide block 74, which effectively prevents damage to the spinning yarn during movement and affects the subsequent test results.

[0060] Specific embodiment four: A spinning tensile strength testing method, using a spinning tensile strength testing device as described in embodiments one to three, includes the following steps:

[0061] During operation, the rolled-up filaments are first installed into the lower fixing mechanism 7;

[0062] Guided by the lower fixing mechanism 7, the spinning thread passes through the interior of the lower fixing mechanism 7 and the upper fixing mechanism 5;

[0063] Then, the upper fixing mechanism 5 moves upward to divide the spinning into multiple strands;

[0064] The upper and lower ends of the spinning are then fixed by the upper fixing mechanism 5 and the lower fixing mechanism 7.

[0065] Then, tensile tests are performed on multiple spinning segments simultaneously through the lower fixing mechanism 7.

[0066] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
