[0065] A dust removal mechanism 8 is provided on the box body 7 and is used to remove dust on the textiles;

[0066] Among them, the smoothing institutions 9 include:

[0067] The caressing plate 91 is arranged inside the box 7, fits on the textile and contacts the outer wall of the right guide tube 5;

[0068] A reciprocating screw rod 95 is rotatably connected to the inner wall of the box body 7;

[0069] The limiting slide bar 96 is fixedly connected to the inner wall of the box body 7, and the outer wall of the limiting slide bar 96 is movably sleeved with a slide seat 94, and the slide seat 94 is also connected to the outer wall of the reciprocating screw rod 95;

[0070] The connecting block 92 is hinged at the bottom of the sliding seat 94 and movably connected in the groove of the smoothing plate 91 .

[0071] The pacification agency 9 also includes:

[0072] Two springs 93 are fixedly connected in the groove and connected to the bottom of the connecting block 92, and are used to elastically push the caressing plate 91 to contact the textile.

[0073] The limiting mechanism 3 comprises:

[0074] The placement grooves 31 are provided on both sides of the top of the fixing plate 1 and are used for placing the textile tubes;

[0075] The arc-shaped limit plate 32 is hinged on the fixed plate 1, and a coil spring is arranged at the hinge to push the arc-shaped limit plate 32 to fit with the axis of the textile tube;

[0076] The textiles on the textile cylinder are sequentially wound around the outer walls of the two guide cylinders 5 and connected to the outer wall of the textile cylinder on the other side.

[0077] The limiting mechanism 3 also includes:

[0078] Two rotating shafts 33 are rotatably connected to the back of the back fixing plate 1, and the outer wall of the rotating shaft 33 is fixedly sleeved with a guide wheel 34, and the outer wall of the guide wheel 34 is in contact with the axis of the spinning cylinder, so as to drive the spinning cylinder to rotate;

[0079] The driving motor 36 is fixedly connected to the back side of the back fixing plate 1 , and the output end of the driving motor 36 is transmission-connected to the two rotating shafts 33 via a pulley set 35 .

[0080] Working principle: When performing textile defect detection, first place the textile tube in the placement groove 31 of the fixed plate 1. The textile passes through the outer walls of the two guide tubes 5 in sequence and contacts the fastening rod 62. When the axis of the textile tube is located in the placement groove 31, the arc-shaped limit plate 32 is reset under the action of the coil spring, deflected downward and abutted against the outer wall of the axis of the textile tube, thereby limiting the textile tube from leaving the placement groove 31. At this time, the drive motor 36 is started, and the drive motor drives the two guide wheels 34 to rotate synchronously through the pulley group 35, thereby driving the axes of the two textile tubes to rotate, realizing the winding and unwinding functions.

[0081] During the movement of the textile, when it passes through the video system 4, the camera in the video system records the textile in real time, and transmits the video data to the computer for analysis to detect the defect situation of the textile;

[0082] During the unwinding process, the motor installed on the fixed plate 1 is started, and the motor drives the reciprocating lead screw 95 to rotate. Under the limiting action of the limiting slide bar 96, the sliding seat 94 moves back and forth along the reciprocating lead screw 95, thereby driving the connecting block 92 and the flattening plate 91 to move back and forth. The flattening plate 91 is elastically pushed by the third spring 93, closely fits the surface of the textile, and abuts against the outer wall of the right guiding cylinder 5. Through the forward and backward movement of the flattening plate 91, the textile is effectively flattened, avoiding wrinkles during winding, so as to ensure that the video system 4 can record clearly and accurately, improving the detection accuracy.

[0083] Furthermore, when the flattening plate 91 is pushed by the third spring 93, it can closely fit the textile, tightly push it and fit it onto the guiding cylinder 5, further improving the flatness performance during winding.

[0084] Please refer to Figures 1-8 , based on the above embodiment, in another embodiment of the present invention, the dust removal mechanism 8 includes:

[0085] A dust suction device 81, fixedly connected to the top of the box body 7;

[0086] A plurality of suction heads 83, installed on the left inner wall of the box body 7 for sucking dust;

[0087] A conduit 82, connected to the plurality of suction heads 83 and the dust suction device 81.

[0088] The dust removal mechanism 8 further includes:

[0089] A plurality of fixed sleeves 84, fixedly connected to the top inner wall of the box body 7;

[0090] A movable rod 85, movably connected to the inner wall of the fixed sleeve 84;

[0091] A contact rod 87, fixedly connected to the bottom of the movable rod 85 and in contact with the upper part of the textile;

[0092] A second spring 86, arranged in the inner wall of the fixed sleeve 84 and connected to the fixed sleeve 84 and the movable rod 85 for resetting the movable rod 85 upward.

[0093] Working principle: During the winding and unwinding process of the textile, the dust suction device 81 is started, and the dust above the textile is sucked through the conduit 82 and the suction heads 83, avoiding dust adhering to the surface of the textile and affecting the video detection effect.

[0094] Meanwhile, the contact rod 87 is located above the textile. When the moving rubber roller 991 contacts the contact groove on the contact plate 97, the second spring 86 will reset the movable rod 85 and the contact rod 87 upward. When the rubber roller 991 disengages from the contact groove on the contact plate 97, the movable rod 85 and the contact rod 87 move downward under the action of the second spring 86. During this process, the contact rod 87 continuously impacts the surface of the textile, causing the dust on the textile to fall off due to vibration, which is convenient for the suction head 83 to adsorb.

[0095] In addition, when the moving textile contacts the contact rod 87, friction and contact separation between the materials will generate static electricity on the contact rod 87, thereby adsorbing the dust on the textile and further improving the dust removal effect.

[0096] Please refer to Figures 1-8 , on the basis of the above embodiment, in another embodiment of the present invention, an L-shaped plate 98 is fixedly connected to the sliding seat 94, a rotating rod 99 is rotatably connected to the L-shaped plate 98, and rubber rollers 991 and oval turntables 992 are respectively fixedly sleeved on both sides of the rotating rod 99;

[0097] A contact plate 97 is fixedly sleeved on the outer wall of the movable rod 85, and a plurality of equally spaced semi-circular grooves are formed at the top of the contact plate 97, and the rubber roller 991 rolls inside the semi-circular grooves;

[0098] The outer wall of the oval turntable 992 is attached to the upper side of the flattening plate 91, and is used to push the flattening plate 91 to rotate around the hinge of the connecting block 92.

[0099] The fastening assembly 6 includes:

[0100] An arc-shaped hole 61 is formed in the fixing plate 1 and is located on the left side of the video system 4;

[0101] An arc-shaped sliding rod 63 is fixedly connected to the inner wall of the arc-shaped hole 61, and the outer wall of the arc-shaped sliding rod 63 is movably sleeved with a fastening rod 62 and is located above the textile;

[0102] A first spring 64 is sleeved on the outer wall of the arc-shaped sliding rod 63, and is used to push the fastening rod 62 to slide on the arc-shaped sliding rod 63 and contact the textile.

[0103] Working principle: The fastening assembly 6 applies a tension force to the textile through the arc-shaped sliding rod 63 and the fastening rod 62. The first spring 64 is sleeved on the outer wall of the arc-shaped sliding rod 63, and pushes the fastening rod 62 to slide on the arc-shaped sliding rod 63 and contact the textile. Through the elastic action of the first spring 64, the fastening rod 62 can adaptively adjust the stress state of the textile to ensure that the textile always remains flat and better cooperate with the detection process;

[0104] In the flattening mechanism, when the rubber roller 991 moves back and forth, it will trigger the rotation of the rubber roller 991, which in turn drives the rotation of the rotating rod 99, causing the elliptical turntable 992 to rotate accordingly. When the side of the elliptical turntable 992 away from the center of the circle touches the flattening plate 91, it will squeeze the flattening plate 91 to deflect around its hinge, thereby tightening the flattening effect on the textile. When it touches the flattening plate 91 on the side close to the center of the circle, the flattening plate 91 resets under the action of the third spring 93, reducing the force on the textile. By continuously changing the force on the textile, the fluttering effect on the textile is further improved, thereby enhancing the flattening effect.

[0105] The present invention provides a detection device for textile defects. There are many methods and ways to specifically implement this technical solution. The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be implemented by existing technologies.
