Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Reference Figure 1-Figure 6 As shown, the present invention provides a yarn high-toughness anti-breakage inspection device, including a base 1, a plurality of pairs of raised platforms 5 are evenly installed at the bottom of the base 1, two pairs of mounting brackets are symmetrically installed on the left and right sides of the base 1, and mounting shafts 2 are installed on the two pairs of mounting brackets. The two mounting shafts 2 are sleeved with rollers 3, and the outer surfaces of the two rollers 3 are provided with locking buckles 4, and the yarn to be tested can be fixed between the two locking buckles 4; two mounting side platforms 6 are symmetrically installed in the front and back of the middle part of the base 1, and a movable mounting side platform 6 is inserted between the two mounting side platforms 6. A lifting shaft rod 7 is provided, and the lifting shaft rod 7 can only be displaced in the height direction of the two mounting side platforms 6. A roller column 8 is fixedly sleeved outside the lifting shaft rod 7, and a capacitive sensor 9 is embedded in the center of the outer surface of the roller column 8. The capacitive sensor 9 is mainly composed of a fixed pole piece, a moving pole piece, a guide wheel and a bracket. When the yarn passes through, the moving pole piece itself is an elastic body, and one end of the yarn guide wheel is fixed to the moving pole piece through an insulator to form a cantilever beam, so that the tension change of the yarn can be detected, and it is used to detect the disconnection / connection state of the yarn abutting on it as the position of the roller column 8 is adjusted;

[0030] A movable side-changing rod 10 is inserted at the front end of the lifting shaft 7. The side-changing rod 10 is horizontally arranged. The side-changing rod 10 is released and tightened by a locking screw 71, which is a simple tightening and loosening operation. Two electric slide rails 61 are symmetrically embedded on the front side of the front mounting side platform 6. The two electric slide rails 61 are respectively installed with a test piece 11 and a test piece 2 12 which match the two ends of the side-changing rod 10, so as to switch the device between two detection states and correspond to different detection needs. Specifically, by adjusting the left and right displacement of the side-changing rod 10 connected to the lifting shaft 7 and the roller 2 8, the test piece 1 11 and the test piece 2 12 can be cooperated to respectively measure the limit value range of the tension required for the yarn to break and the subsequent durability data when the yarn reaches the design limit value.

[0031] In a further embodiment, referring to Figure 5 The test piece 12 includes a slider 121, which is slidably installed in the electric slide rail 61 close to the test piece 12, and a fixed plate 122 is fixedly installed on the slider 121. Two fixed frames 126 are symmetrically installed on the surface of the fixed plate 122. The upper ends of the two fixed frames 126 are commonly fixedly connected to a fixed top plate 124, and a connecting seat 125 is installed on the top of the fixed top plate 124. The connecting seat 125 is for the end of the side-changing rod 10 to be plugged in; the front side of the fixed plate 122 is fixedly connected to a lining plate 123, and the back side of the upper end of the lining plate 123 is fixedly connected to the side of the fixed top plate 124.

[0032] In this embodiment, the yarn to be tested is fixed at both ends by two locking buckles 4 on two rollers 3, so that the middle section of the yarn to be tested abuts against the capacitive sensor 9, and then the right-biased edge-changing rod 10 is fixed together with the connecting seat 2 125 in the test piece 2 12, and the steady rise of the slider 2 121 in the electric slide rail 61 can drive the lifting shaft 7 and the roller 2 8 to rise steadily. When the breaking limit value is finally reached, the capacitive sensor 9 detects the sudden disappearance of the tension, so that the limit value of the pulling force required for the yarn to break can be measured, and then through multiple groups of control experiments, accurate measurement data can be obtained, and the limit value range of the pulling force required for the yarn to break can be obtained.

[0033] In a further embodiment, referring to Figure 5 and Figure 6The test piece 11 includes a slider 111 and a rocking piece 117. The slider 111 is slidably installed in the electric slide rail 61 close to the test piece 11. A fixed plate 112 is fixedly installed on the slider 111. Two telescopic frames 116 are symmetrically installed on the surface of the fixed plate 112. The upper ends of the two telescopic frames 116 are commonly connected with a movable top plate 114. A connecting seat 115 is installed on the top of the movable top plate 114. The connecting seat 115 is used for the end of the side-changing plug rod 10 to be plugged. A lining plate 113 is fixedly connected to the front side of the fixed plate 112. The back side of the upper end of the lining plate 113 is connected to the side of the fixed top plate 124 in a fitting sliding manner. The lining plate 113 plays an isolation and protection role for the rocking piece 117 and the telescopic frame 116 in the test piece 11;

[0034] The telescopic frame 116 includes a telescopic rod 1161 and a support spring 1162 sleeved outside the telescopic rod 1161. The two ends of the telescopic rod 1161 are respectively fixedly connected to the fixed plate 112 and the movable top plate 114. The head and tail ends of the support spring 1162 are also respectively fixedly connected to the fixed plate 112 and the movable top plate 114. The telescopic frame 116 supports the reciprocating movable top plate 114, thereby improving the stability of the movable top plate 114.

[0035] In this embodiment, the yarn to be tested is fixed at both ends by two locking buckles 4 on two rollers 3, so that the middle section of the yarn to be tested abuts against the capacitive sensor 9, and then the left-biased edge-changing rod 10 is fixed together with the connecting seat 115 in the test piece 11, and the steady rise of the slider 111 in the electric slide rail 61 can drive the lifting shaft 7 and the roller 2 8 to rise steadily. When the capacitive sensor 9 detects that it has reached the preset limit value when the yarn is designed, the slider 111 stops rising, and the shaking piece 117 intervenes to prompt the movable top plate 114 and the connecting seat 115 to move up and down regularly, thereby simulating the repeated pulling of the yarn under actual use. Finally, at a certain node, the capacitive sensor 9 detects the sudden disappearance of the tension, so that the durability data of the yarn when it reaches the design limit value can be measured. After that, through multiple groups of control experiments, accurate measurement data can be obtained, and the subsequent durability data of the yarn when it reaches the design limit value can be obtained.

[0036] In a further embodiment, referring to Figure 6 The rocking member 117 includes a motor mounting platform 1171 fixed on the top surface of the fixed plate 112, a driving motor 1172 is mounted on the motor mounting platform 1171, a cam 1173 is fixedly mounted on the output shaft of the driving motor 1172, a U-shaped frame 1175 is fixedly mounted on the bottom surface of the movable top plate 114, a roller 1174 is rotatably mounted in the U-shaped frame 1175 through a pin shaft, and the roller 1174 is in close contact with the cam 1173;

[0037] The shaking piece 117 also includes a straight piece 1176, which is made of stainless steel with a thickness of 2-3 cm, so that it has sufficient bending resistance to ensure its reliability in use; the outer edges of the roller 1174 and the cam 1173 are correspondingly provided with narrow gaps matching the straight piece 1176, and when the straight piece 1176 is inserted between the cam 1173 and the roller 1174, it can limit the position and prevent the two from moving. In this way, when the device is idle, the insertion of the straight piece 1176 can prevent the movable top plate 114 from shaking or being unstable. When the test piece 11 is needed, the straight piece 1176 can be removed, which is simple and reliable.

[0038] In this embodiment, when it is necessary to drive the movable top plate 114 to move back and forth, that is, it is necessary to drive the lifting shaft 7 and the roller 28 to move back and forth, and to measure the durability data when the design limit value is reached, the drive motor 1172 is started to drive the cam 1173 to rotate. The rotation of the cam 1173 can drive the roller 1174 to move accordingly, thereby realizing the lifting and lowering of the movable top plate 114, and can simulate the repeated pulling of the yarn under actual use conditions. Finally, at a certain node, the capacitive sensor 9 detects the sudden disappearance of the tension, thereby measuring the durability data of the yarn when it reaches the design limit value.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
