Description

Technical Field

[0001] The present invention relates to the technical field of silk breaking force detection, and particularly to a silk detection breaking mechanism. Background Art

[0002] During the production process of silk, it is necessary to detect its tensile strength and breaking point. The current detection breaking mechanism simulates the tensile force that the silk receives in actual applications until the silk breaks. Currently, in the detection of silk breaking force, the silk is fixed by a fixture with jaws at both ends. However, during the process of pulling the silk, the silk often disengages from the fixture, and the tensile force distribution during the detection will no longer be uniform. This will cause the silk to break under abnormal stress conditions, resulting in the detection result being unable to truly reflect the actual breaking force of the silk, and the detected tensile force being inaccurate, making it impossible to measure the actual strength of the silk. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides a silk detection breaking mechanism, which solves the problem that the silk disengages from the fixture in the prior art, resulting in the silk breaking under abnormal stress conditions and affecting the accuracy of the detection result.

[0004] To solve the above technical problems, the present invention provides the following technical solutions:

[0005] A silk detection breaking mechanism includes a base, a torque sensor, and a breaking tensile force assembly. The torque sensor is arranged on one side of the top of the base and is used for continuously reading the value of the tightened silk. When the silk breaks, the maximum detected value is captured as the breaking force result. The breaking tensile force assembly is arranged on the base and is used for detecting the breaking force by applying a tensile force to the silk. The breaking tensile force assembly includes a limit seat arranged at the bottom of the torque sensor and fixed to the base, and a movable seat arranged at the bottom of the limit seat. Both the limit seat and the movable seat are provided with a wire clamping and rotating assembly for clamping the silk to be detected and rotating and winding it. The breaking tensile force assembly further includes a pushing assembly arranged on the base for pushing the movable seat to move and apply a tensile force to the silk. The wire clamping and rotating assembly includes a stepping motor respectively fixed to one end of the limit seat and the movable seat, and a clamping assembly arranged on the output shaft of the stepping motor for clamping the silk to be detected. The stepping motor drives the clamping assembly to rotate to wind the silk to be detected tightly to prevent it from slipping off.

[0006] As a further optimized solution of the present invention, the pushing assembly includes a servo motor arranged on one side of the torque sensor and fixed to the base, and a transmission vertical shaft fixed to the bottom of the output shaft of the servo motor. A moving seat is slidably arranged on the transmission vertical shaft. When the output shaft of the servo motor rotates, it drives the moving seat to move linearly along the transmission vertical shaft. One side of the moving seat is fixedly connected to the movable seat by a bolt.

[0007] As a further optimization scheme of the present invention, the clamping assembly includes a support base fixedly arranged on the output shaft of the stepping motor, and a clamping cylinder is fixedly arranged on one side of the support base.

[0008] As a further optimization scheme of the present invention, movable jaws are fixedly arranged on the two output ends of the clamping cylinder, and a groove for winding the silk thread is integrally formed on the movable jaws.

[0009] As a further optimization scheme of the present invention, a cleaning assembly for sweeping and detecting the waste thread after breakage is also arranged on one side of the base. The cleaning assembly includes a support vertical frame fixedly arranged on one side of the base, a rodless cylinder is fixedly installed on one side of the support vertical frame, and a piston slider is slidably arranged on the shaft of the rodless cylinder.

[0010] As a further optimization scheme of the present invention, a mounting frame is fixedly installed on the piston slider, and a cleaning brush matching the clamping assembly is fixedly arranged on one side of the mounting frame.

[0011] As a further optimization scheme of the present invention, a connecting seat fixed to the base is fixed on the top of the torque sensor, and a storage box for collecting the waste thread after detection is arranged on one side of the bottom of the base.

[0012] As a further optimization scheme of the present invention, limiting vertical rails fixed to the base are respectively arranged at both ends on one side of the movable seat, sliding seats are respectively slidably arranged on the two limiting vertical rails, and both ends of the movable seat are fixedly connected to the two sliding seats respectively.

[0013] By means of the above technical scheme, the present invention provides a silk thread breakage detection mechanism, which has at least the following beneficial effects:

[0014] 1. The present invention applies a tensile force to the silk thread through the breakage tensile force assembly until it is broken to detect the breaking force. The clamping and rotating assembly first clamps the silk thread to be detected and then rotates and winds it. Then, a tensile force is applied to the silk thread through the pushing assembly, which helps to ensure that the silk thread can be evenly distributed under tension, avoid the deviation of the detection result caused by uneven stress, and then improve the measurement accuracy of the breaking force. At the same time, the silk thread is more firmly fixed in the fixture, which can enhance the contact force between the silk thread and the fixture and reduce the risk of the silk thread slipping off, thus improving the reliability of the detection.

[0015] 2. The present invention clamps the silk thread to be detected by setting the clamping assembly, and then drives the clamping assembly to rotate by the stepping motor to wind the silk thread to be detected to prevent it from slipping off. After the silk thread is rotated and wound tightly, it will bear tensile forces in different directions. The tensile properties of the silk thread can be more comprehensively understood through tensile force tests in different directions, and it is avoided that the silk thread falls off due to uneven stress or fixture problems in the initial stage of the tensile force, thereby reducing the number of interruptions in the experiment and improving the efficiency of the entire test process.

[0016] 3. The present invention is provided with a cleaning component to sweep the broken silk thread. If the broken silk thread is not cleaned in time, it may interfere with subsequent tests. Especially in multiple tests, the cleaning component can quickly remove the broken silk thread, avoid the interference of silk thread residues on the next test, and improve the efficiency and continuity of the test. Moreover, the remaining silk thread may get stuck in the device, especially in fixtures, tension sensors or other detection components. The cleaning component can avoid potential damage to the device caused by silk thread residues, thereby reducing the maintenance requirements of the device and extending the service life of the device.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] In the detection of the breaking force of the silk thread, if the silk thread detaches from the fixture, it may lead to a series of defects or problems, which usually affect the accuracy and reliability of the test. To improve the measurement accuracy of the breaking force and the reliability of the detection, as Figure 1 - Figure 2 and Figure 4 shown, the first embodiment of the present invention is: a silk thread detection and breaking mechanism, including a base 1, a torque sensor 2, and a breaking tensile force assembly 3. A connecting seat 5 fixed to the base 1 is fixed at the top of the torque sensor 2, and a storage box 6 for collecting waste silk after detection is provided on one side of the bottom of the base 1. The waste silk broken after detection falls into the storage box 6 for collection. The torque sensor 2 is arranged on one side of the top of the base 1, and it is used to continuously read the value of the tightened silk thread. When the silk thread breaks, the maximum detected value is captured as the breaking force result.

[0032] To ensure that the silk thread can be evenly stressed when being pulled and avoid the deviation of the detection result caused by uneven stress, the breaking tensile force assembly 3 is arranged on the base 1, and it is used to detect the breaking force by applying a tensile force to the silk thread. The breaking tensile force assembly 3 includes a limit seat 31 arranged at the bottom of the torque sensor 2 and fixed to the base 1, and a movable seat 32 arranged at the bottom of the limit seat 31. At both ends of one side of the movable seat 32, limit vertical rails 33 fixed to the base 1 are respectively arranged. Sliding seats 34 are respectively slidably arranged on the two limit vertical rails 33, and both ends of the movable seat 32 are respectively fixed to the two sliding seats 34, ensuring that the movable seat 32 moves more stably in the vertical direction.

[0033] Clamping wire rotation components 35 are provided on both the limit seat 31 and the movable seat 32. They are used to clamp the wire to be detected and rotate it to wind it tightly. The clamping wire rotation component 35 includes a stepping motor 351 fixedly provided at one end of the limit seat 31 and the movable seat 32 respectively, and a clamping component 352 provided on the output shaft of the stepping motor 351 for clamping the wire to be detected. The stepping motor 351 winds the wire to be detected tightly to prevent it from slipping off by driving the clamping component 352 to rotate; the clamping component 352 includes a support seat 3521 fixedly provided on the output shaft of the stepping motor 351. A clamping cylinder 3522 is fixedly provided on one side of the support seat 3521. Movable jaws 3523 are fixedly provided on the two output ends of the clamping cylinder 3522. Grooves for winding the wire are integrally formed on the movable jaws 3523. The wire to be detected is sent between the two movable jaws 3523 on the limit seat 31 and the movable seat 32 by a manipulator. The clamping cylinder 3522 drives the two movable jaws 3523 to move towards the middle to clamp the wire. Then, the output shaft of the stepping motor 351 rotates, driving the two movable jaws 3523 to rotate, and winding the wire around the two movable jaws 3523.

[0034] A pushing component 36 is further provided on the base 1. It is used to push the movable seat 32 to move and apply a tensile force to the wire. The pushing component 36 includes a servo motor 361 provided on one side of the torque sensor 2 and fixed to the base 1, and a transmission vertical shaft 362 fixedly provided at the bottom of the output shaft of the servo motor 361. A moving seat 363 is slidably provided on the transmission vertical shaft 362. When the output shaft of the servo motor 361 rotates, it drives the moving seat 363 to move linearly along the transmission vertical shaft 362. One side of the moving seat 363 is fixedly connected to the movable seat 32 by bolts. After the wire is clamped and fixed, the servo motor 361 is started. The output shaft of the servo motor 361 drives the transmission vertical shaft 362 to rotate. The transmission vertical shaft 362 drives the moving seat 363 to move downward. The moving seat 363 pulls one end of the wire thereon downward, applying a tensile force to the wire to perform a breaking force test.

[0035] Embodiment 2

[0036] To avoid interference of wire residues with the next test and improve the efficiency and coherence of the test, as Figure 3As shown in the figure, this is the second embodiment of the present invention: on one side of the base 1, a cleaning component 4 is further provided for cleaning the waste wire after the brushing detection is broken. The cleaning component 4 includes a supporting vertical frame 41 fixedly arranged on one side of the base 1. On one side of the supporting vertical frame 41, a rodless cylinder 42 is fixedly installed. A piston slider 43 is slidably arranged on the shaft of the rodless cylinder 42. An installation frame 44 is fixedly installed on the piston slider 43. On one side of the installation frame 44, a cleaning brush 45 matching the clamping component 352 is fixedly arranged. After the silk breaking force detection is completed, the rodless cylinder 42 is started. The rodless cylinder 42 drives the piston slider 43 to move downward. The piston slider 43 drives the installation frame 44 and the cleaning brush 45 to move downward. The cleaning brush 45 sweeps the waste silk on the two movable jaws 3523 into the storage box 6 for collection.

[0037] In the present invention, the wire clamping and rotating component 35 first clamps the wire to be detected and then rotates and winds it tightly. Then, the pushing component 36 applies a pulling force to the wire to detect the wire breaking force. At the same time, the torque sensor 2 is used to record the wire breaking force result. Finally, the cleaning component 4 is used to clean the broken wire, which can avoid the deviation of the detection result caused by uneven force, and improve the measurement accuracy and detection efficiency of the wire breaking force.

[0038] During the actual use of this detection and breaking mechanism, first, the wire to be detected is sent between the two movable jaws 3523 on the limit seat 31 and the movable seat 32 by a manipulator. Then, the clamping cylinders 3522 on the limit seat 31 and the movable seat 32 are started simultaneously. The two output ends of the clamping cylinder 3522 drive the two movable jaws 3523 to move towards the middle to clamp the wire. Then, the output shaft of the stepping motor 351 rotates, driving the support seat 3521 to rotate. The support seat 3521 drives the two movable jaws 3523 thereon to rotate, winding the wire into the grooves on the two movable jaws 3523, so that the clamping components 352 on the limit seat 31 and the movable seat 32 respectively clamp the two movable ends of the wire.

[0039] Then, the servo motor 361 is started. The output shaft of the servo motor 361 drives the transmission vertical shaft 362 to rotate. The transmission vertical shaft 362 drives the moving seat 363 to move downward. The moving seat 363 pulls one end of the wire thereon downward to apply a pulling force to detect the breaking force. The torque sensor 2 continuously reads the value of the tightened wire. When the wire breaks and grabs the maximum detection value, it is the breaking force result. Finally, the rodless cylinder 42 is started again. The rodless cylinder 42 drives the piston slider 43 to move downward. The piston slider 43 drives the installation frame 44 and the cleaning brush 45 to move downward. The cleaning brush 45 sweeps the waste silk on the two movable jaws 3523 into the storage box 6 for collection.
