[0002] In the production process of textile fabrics, there are many processing steps. During these processes, the textile fabrics are prone to defects such as damage, color difference, and attachments. Therefore, before leaving the factory, it is necessary to use a defect detection device to conduct camera detection to determine the number of defects in the textile fabrics to determine whether they meet the standards;

[0003] The existing textile fabric defect detection devices on the market usually require manual work to first wrap the end of the processed and wound fabric roll around the detection winding roller for several turns, and then rotate the detection winding roller. In the process of the detection winding roller rotating to continuously wind the end of the fabric roll, the fabric will move past the defect camera detector before being transmitted and wound to the detection winding roller. The detectors arranged up and down will photograph and detect the front and back sides of the passing fabric, and record the number of defects for subsequent viewing.

[0020] Two defect camera detectors are installed on the outer wall of the fabric detection frame.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In the present invention, when the second rotating disk moves, it will move with the third horizontal axis. When the third horizontal axis moves, it will move the pressing sleeve toward the direction close to the winding roller, and gradually clamp the end of the fabric roll between the surface of the winding roller and the outer wall of the pressing sleeve. Since the surface of the sponge layer protrudes from the outer wall of the pressing sleeve, the sponge layer also has a pressing and clamping effect on the end surface of the fabric roll, thereby completing the fixation of the end of the fabric roll.

[0023] In the present invention, the air cylinder is continuously started to cause the fifth horizontal axis to continue to slide downward along the guide groove until it slides to the stable section of the guide groove. At this time, when continuing to move, the first inclined surface of the outer wall of the first resistance block will conflict with the second inclined surface of the outer wall of the second resistance block, causing the first resistance block to be forced to carry the fourth horizontal axis and the pressing sleeve to slide in the direction away from the first pressing plate. At this time, the pressing sleeve slides along the surface of the sponge layer and the outer wall of the first pressing plate in the direction of separating from the first pressing plate. During the sliding process, the pressing sleeve is still in a state of pressing the end of the fabric roll, and at this time, the pressing sleeves on both sides slide in opposite directions, which will pull the clamped end of the fabric roll flat toward opposite sides;

[0024] Because the sponge layer is tightly pressed against the surface of the fabric roll, when the pressing sleeve plate slides in contact with the fabric roll and the surface of the winding roller, the end of the fabric roll is still squeezed by the sponge layer on the surface of the winding roller and will not fall off.

[0025] In the present invention, since the sponge layer presses the fabric roll more tightly at this time, the sponge layer will be forced to deform and compress. At this time, the distance between the first pressure plate and the surface of the winding roller is closer, so the pressure of the multi-layer fabric roll wound on the surface of the winding roller on the surface of the first pressure plate will also be reduced. At this time, the first pressure plate will move more smoothly in the direction away from the winding roller, and the first pressure plate will not be inconvenient to withdraw due to the winding of multiple layers of winding rollers. Moreover, since multiple layers of fabric rolls have been wound outside the winding roller, even if there is no sponge layer and the first pressure plate pressing the end of the fabric roll on the outer wall of the winding roller, the friction between the multiple layers of fabric rolls will prevent it from detaching from the outer wall of the winding roller.

[0054] The inner wall of the guide groove 40 is provided with a descending groove 4001;

[0055] The outer wall of the fabric detection frame 1 is provided with an inclined groove 101 for placing the fabric roll 102;

[0056] Two defect camera detectors 39 are installed on the outer wall of the fabric detection frame 1.

[0057] In this embodiment: during the production process of textile fabrics, they will go through a variety of processing processes. During these processes, defects such as damage, color difference, and attachments are likely to occur on the textile fabrics. Therefore, before leaving the factory, it is necessary to use a defect detection device to perform video detection to determine the number of defects in the textile fabrics to determine whether they meet the standards;

[0058] The existing textile fabric defect detection devices on the market usually require manual work to first wrap the end of the processed and wound fabric roll around the detection winding roller for several turns, and then rotate the detection winding roller. In the process of the detection winding roller rotating to continuously wind up the end of the fabric roll, the fabric will move through the defect camera detector before being transmitted and wound up to the detection winding roller. The detectors arranged up and down will take pictures of the front and back sides of the fabric passing through, and record the number of defects for subsequent viewing. Manually wrapping the end of the fabric around the winding roller is not only troublesome, but also inconvenient to smooth the end, which easily causes the problem of uneven winding during the winding process of the detection winding roller.

[0059] The fabric roll 102 is placed in the inclined groove 101 to prevent the fabric roll from sliding down and the fabric roll 102 from sliding down.

[0060] During the sliding of the fifth horizontal axis 131 along the track of the guide groove 40, the fixed block 38 which is sleeved on the outer wall of the fifth horizontal axis 131 rotates and moves accordingly, and the moving track of the fixed block 38 causes the fixed block 38 to contact the outer wall of the contact plate 41, causing the fixed block 38 to rotate along the outer wall of the fifth horizontal axis 131. During the rotation of the fixed block 38, the first horizontal axis 29 performs a circular motion. At this time, the first horizontal axis 29 moves the second slider 28 at one end during the circular motion, and the second slider 28 slides the third slider 251 toward the inner wall of the fixed frame 24, and the third slider In order to prevent the second slider 28 from getting stuck during the sliding process of the third slider 251 toward the inner wall of the fixed frame 24, the third slider 251 will slide downward along the inner wall of the third slide groove 26 and compress the fifth spring 27 to adapt to the movement. As the third slider 251 slides toward the inner wall of the fixed frame 24, the third slider 251 will continuously compress the fourth spring 25 to facilitate subsequent resetting. At this time, the movement of the third slider 251 will move the second horizontal axis 30 synchronously, and the movement of the second horizontal axis 30 will move the second rotating disk 21 together. The movement of the second rotating disk 21 will cause the third spring 19 to be compressed, which is convenient for subsequent resetting.

[0061] When the second rotating disk 21 moves, it will move with the third horizontal axis 31. When the third horizontal axis 31 moves, it will move with the first pressing plate 32, the sponge layer 321 and the pressing sleeve plate 33 towards the direction close to the winding roller 16, and gradually clamp the end of the fabric roll 102 between the surface of the winding roller 16 and the outer wall of the pressing sleeve plate 33. Since the surface of the sponge layer 321 protrudes from the outer wall of the pressing sleeve plate 33, the sponge layer 321 also has a pressing and clamping effect on the end surface of the fabric roll 102, and the end of the fabric roll 102 is fixed at this time.

[0062] At this time, the cylinder 2 is continued to be started, so that the fifth horizontal axis 131 continues to slide downward along the guide groove 40 until it slides to the stable section of the guide groove 40. At this time, when continuing to move, the first inclined surface 37 of the outer wall of the first contact block 36 will contact the second inclined surface 44 of the outer wall of the second contact block 43, so that the first contact block 36 is forced to carry the fourth horizontal axis 34 and the pressing sleeve 33 to slide in the direction away from the first pressure plate 32. At this time, the pressing sleeve 33 slides along the surface of the sponge layer 321 and the outer wall of the first pressure plate 32 in the direction of separating from the first pressure plate 32. During the sliding process, the pressing sleeve 33 is still in the state of pressing the end of the fabric roll 102, and at this time, the pressing sleeves 33 on both sides slide in opposite directions, which will pull the clamped end of the fabric roll 102 flat towards opposite sides;

[0063] It should be noted that the elastic force of the seventh spring 47 is greater than the elastic force of the sixth spring 35, so the sixth spring 35 will be pulled first to cause the pressing sleeve 33 to slide. When the pressing sleeve 33 is out of contact with the winding roller 16, and at this time the first abutment block 36 will abut against the outer wall of the sliding plate 46 along the second inclined surface 44, at this time the first abutment block 36 will abut against the sliding plate 46 to cause the sliding plate 46 to slide along the outer wall of the guide rod 45 and compress the seventh spring 47 so as to slide along the inner wall of the fourth slide groove 441. It should be noted that since the sponge layer 321 is tightly pressed against the surface of the fabric roll 102, when the pressing sleeve 33 is in sliding contact with the surface of the fabric roll 102 and the winding roller 16, the end of the fabric roll 102 is also squeezed by the sponge layer 321 on the surface of the winding roller 16 and will not fall off.

[0064] At this time, the transmission motor 11 is started, and the transmission motor 11 drives the rotating disk 8 on one side to rotate, and the rotating disk 8 drives the prism 10 to rotate, and the prism 10 drives the sleeve 14 to rotate. Since the sleeve 14 is square, the second square groove 17 is subjected to force when it rotates, and finally the winding roller 16 is driven to rotate;

[0065] As the fifth horizontal axis 131 continues to move, when the fixed block 38 moves and contacts the rising contact plate 42, since the rising contact plate 42 is higher than the contact plate 41, when the fixed block 38 contacts, it will rotate a larger angle along the outer wall of the fifth horizontal axis 131, at this time, the first pressure plate 32 and the sponge layer 321 will be more closely attached, and at this time, the second rotating disk 21 will rotate accordingly. When the second rotating disk 21 rotates accordingly, it will rotate synchronously with the third horizontal axis 31, the first pressure plate 32 and the sponge layer 321. It should be noted that the initial state of the second rotating disk 21 is that the center of the circle deviates from the position of the sleeve 14. At the final position, the center of the second rotating disk 21 coincides with the position of the sleeve 14. At this time, when the second rotating disk 21 rotates, the second horizontal axis 30 can slide normally along the second annular groove 211. It should be noted that, therefore, at this time, the winding roller 16 will rotate and rewind with the clamped end of the fabric roll 102, and the fabric on the fabric roll 102 will be pulled and rolled around the outer wall of the winding roller 16 during the rotation process. It should be noted that when the second rotating disk 21 rotates, the second horizontal axis 30 will slide along the second annular groove 211 to prevent it from getting stuck, and the fifth horizontal axis 131 will also slide along the first annular groove 13 to prevent it from getting stuck;

[0066] When the fifth transverse axis 131 continues to slide along the guide groove 40, it will pass through the descending groove 4001. When the fifth transverse axis 131 slides through the descending groove 4001, the resistance of the fifth transverse axis 131 to the first rotating disk 12 will become smaller and smaller, prompting the second spring 9 to continuously rebound. The rebound of the second spring 9 brings the first rotating disk 12, the second rotating disk 21, the third transverse axis 31 and the first pressure plate 32 to move synchronously in the direction away from the winding roller 16. At this time, the sleeve 14 will gradually be more and more sleeved on the outer wall of the prism 10, and the movement of the second rotating disk 21 will resist the fixed frame 24. In order to prevent the fixed frame 24 from hindering the movement of the second rotating disk 21, the fixed frame 24 will press against the guide column 82 after being resisted to make it slide in the direction close to the support frame 7. During the sliding process, the reset spring 81 is compressed to facilitate subsequent reset.

[0067] Since the rising abutment plate 42 is higher than the abutment plate 41, when the fixing block 38 abuts against it, it will rotate at a greater angle along the outer wall of the fifth horizontal axis 131. Therefore, at this time, the sponge layer 321 presses the fabric roll 102 more tightly, causing the sponge layer 321 to be deformed and compressed under force. At this time, the distance between the first pressure plate 32 and the surface of the winding roller 16 is closer, so the pressure of the multi-layer fabric roll 102 wound on the surface of the winding roller 16 on the surface of the first pressure plate 32 will also be reduced. At this time, the first pressure plate 32 will move more smoothly in the direction away from the winding roller 16, and the first pressure plate 32 will not be inconvenient to withdraw due to the winding of the multi-layer winding roller 16. Moreover, since the multi-layer fabric roll 102 has been wound outside the winding roller 16, even if there is no sponge layer 321 and the first pressure plate 32 pressing the end of the fabric roll 102 on the outer wall of the winding roller 16, the friction between the multi-layer fabric roll 102 will prevent it from separating from the outer wall of the winding roller 16.

[0068] At this time, the transmission motor 11 is started to continue to reel in the fabric roll 102. During the reeling process, more fabric rolls 102 will pass through the position between the upper and lower defect camera detectors 39 and be photographed and detected, thereby completing the detection of the fabric roll 102. When all the fabric rolls 102 are reeled onto the outer wall of the reeling roller 16, the detection is completed. The cylinder 2 is started again to cause the fifth horizontal axis 131 to continue to slide along the descending groove 4001. At this time, since the inclined surface of the descending groove 4001 becomes deeper and deeper, the sleeve 14 finally disengages from the second square groove 17. At this time, the reeling roller 16 falls and the detection is completed.

[0069] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
