[0024] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0025] As attached Figure 1 To Attachment Figure 5 As shown:

[0026] Embodiment 1: The utility model provides a grey cloth weaving defect detection device, including a platform assembly 1, the platform assembly 1 includes a mounting platform 101, a mounting frame 102 and a detection sensor 103, the mounting frame 102 is fixedly mounted on the top of the mounting platform 101, and the detection sensor 103 is fixedly mounted on the top of the mounting frame 102; it also includes a conveying assembly, the conveying assembly is composed of a winding mechanism 2 and a tension mechanism 3;

[0027] The winding mechanism 2 includes a mounting seat a201, a driving motor 202 and a winding fixed roller 203. The mounting seat a201 is fixedly mounted on the side of the mounting platform 101, and the driving motor 202 is fixedly mounted on the side of the mounting seat a201. The winding fixed roller 203 is rotatably connected to the inside of the mounting seat a201, and the rotating shaft of the driving motor 202 is drivingly connected to one end of the winding fixed roller 203.

[0028] The tension mechanism 3 includes a mounting base b301, a release fixing roller 302, a tension disc 303, a control disc 304 and an adjusting rod 305. The mounting base b301 is fixedly installed on the side of the mounting platform 101, and the release fixing roller 302 is rotatably connected to the side of the mounting base b301. The tension disc 303 is inserted into the inside of the mounting base b301, and the control disc 304 is inserted into the inside of the mounting base b301. The adjusting rod 305 is rotatably connected to the inside of the mounting base b301.

[0029] In the embodiment of the present disclosure, a to-be-detected blank fabric roller is fixedly installed on the outside of the release fixing roller 302, and a winding roller is fixedly installed on the outside of the winding fixing roller 203. The blank fabric is wound around the blank fabric roller, and the release end of the blank fabric passes through the inside of the mounting frame 102 and is fixed to the winding roller. When the winding fixing roller 203 rotates, it can drive the winding roller to rotate. When the winding roller rotates, it can rewind the blank fabric on the blank fabric roller onto the winding roller, and the blank fabric can be detected by the detection sensor 103 when passing through the mounting frame 102, enabling continuous and uninterrupted detection of the blank fabric.

[0030] In the embodiments of the present disclosure, tension tooth rings 3031 are provided on the side surfaces of the rotating shafts of the release fixed rollers 302 and the side surfaces of the tension discs 303. The cross-sectional shape of each tooth of the tension tooth ring 3031 is a right triangle. When the release fixed roller 302 rotates towards the direction of releasing the base fabric, the hypotenuses of the teeth of the two tension tooth rings 3031 are in contact and extrusion with each other. A tension top spring 3041 is provided on the side surface of the control disc 304, and the two ends of the tension top spring 3041 are respectively abutted against the side surface of the control disc 304 and the side surface of the tension disc 303. During use, there is a certain resistance when the release fixed roller 302 rotates. Thus, through this release resistance, when the winding fixed roller 203 rotates to realize the detection and winding of the base fabric, the base fabric can be conveyed with a certain tension. There is always a certain tension when the base fabric is released, which is convenient for the operation of defect detection. Under the action of the tension top spring 3041, the teeth between the two tension tooth rings 3031 are engaged with each other. Therefore, when the winding fixed roller 203 rotates, it needs to overcome the engagement force obtained by the hypotenuses of the teeth of the two tension tooth rings 3031 through the tension top spring 3041. This force is the tension generated during the conveying and detection of the base fabric. When the tension of the base fabric is less than the engagement relationship maintained by the tension top spring 3041 between the hypotenuses of the teeth of the two tension tooth rings 3031, at this time, the release fixed roller 302 cannot rotate. When the winding fixed roller 203 drives the winding roller to rotate to realize the winding of the base fabric, since the release fixed roller 302 cannot rotate to release the base fabric, the base fabric that has been released will be pulled by the winding fixed roller 203 to increase the surface tension of the base fabric, so as to tighten the base fabric for detection. It is convenient to use and the detection is accurate. As the winding fixed roller 203 rotates, the surface tension of the base fabric will gradually increase until the tension is greater than the engagement relationship maintained by the tension top spring 3041 between the hypotenuses of the teeth of the two tension tooth rings 3031. At this time, the hypotenuses of the teeth of the two tension tooth rings 3031 are in contact and extrusion with each other, causing the tension disc 303 to move to one side and compress the tension top spring 3041 until the tension tooth ring 3031 of the release fixed roller 302 rotates by the angle of one tooth, and then the tension top spring 3041 is released again. At this time, the tension of the base fabric will be released, avoiding damage to the base fabric due to continuously increasing tension. And then the conveying assembly will repeat the above steps to realize the conveying and tension control of the base fabric. It is convenient and flexible to use, and has a high degree of automation.

[0031] In the embodiment of the present disclosure, the outer surface of the rod body of the adjusting rod 305 is provided with threads, and the adjusting rod 305 is screwed inside the control disc 304 through the threads of the rod body. The rod body of the adjusting rod 305 passes through the inside of the tension disc 303. During use, the adjusting rod 305 can realize the function of regulating the tension during the conveying of the greige cloth, and can adapt to the defect detection operation of greige cloths of different types and specifications. When the adjusting rod 305 is rotated, the adjusting rod 305 can drive the control disc 304 to move and change its use position through the threads of the rod body. The change in the use position of the control disc 304 changes the initial compression length of the tension top spring 3041, that is, changes the tension force that overcomes the tension top spring 3041 to maintain the clamping relationship between the tooth hypotenuses of the two tension gear rings 3031. The regulation is convenient, and the flexibility and adaptability are extremely strong.

[0032] The specific usage mode and function of this embodiment:

[0033] In the utility model, the tension in the process of conveying and detecting the grey cloth is adjusted. The function of adjusting the tension in the process of conveying the grey cloth can be realized by adjusting the rod 305, and the defect detection operation of grey cloth of different types and specifications can be adapted. When the adjusting rod 305 is rotated, the adjusting rod 305 can drive the control disk 304 to move and change the use position through the rod body thread. The change of the use position of the control disk 304 changes the initial compression length of the tension top spring 3041, that is, changes the tension force that overcomes the tension top spring 3041 to maintain the clamping relationship between the bevel edges of the gear teeth of the two tension tooth rings 3031. Then, the grey cloth roller is fixed on the release fixed roller 302, and the winding roller is fixed on the winding fixed roller 203. The grey cloth passes through the mounting frame 102 and is fixed on the winding roller. After that, when the power of the driving motor 202 is turned on, the winding fixed roller 203 can drive the winding roller to rotate to realize the winding and conveying operation of the grey cloth, and the grey cloth can be detected by the detection sensor 103 when passing through the mounting frame 102, and the grey cloth can be continuously and uninterruptedly detected. There is a certain resistance when the fixed roller 302 is released to rotate, so that the grey cloth can be conveyed with a certain tension when the winding fixed roller 203 rotates to realize the detection and winding of the grey cloth. There is always a certain tension in the grey cloth when it is released, which is convenient for the operation of defect detection. Under the action of the tension top spring 3041, the two tension tooth rings 3 The teeth of the two tension toothed rings 3031 are engaged with each other, so the winding and fixing roller 203 needs to overcome the engaging force obtained by the tension top spring 3041 between the beveled edges of the teeth of the two tension toothed rings 3031 when rotating. This force is the tension generated by the grey cloth during the conveying and detection process. When the tension of the grey cloth is less than the engaging relationship between the beveled edges of the teeth of the two tension toothed rings 3031 maintained by the tension top spring 3041, the releasing and fixing roller 302 cannot rotate. When the winding and fixing roller 203 drives the winding roller to rotate to achieve the winding of the grey cloth, since the releasing and fixing roller 302 cannot rotate to release the grey cloth, the grey cloth that has been released will be pulled by the winding and fixing roller 203 to increase the surface tension of the grey cloth, thereby The cloth is stretched tight for detection. With the rotation of the winding fixed roller 203, the surface tension of the grey cloth will gradually increase until the tension is greater than the tension top spring 3041 to maintain the clamping relationship between the beveled edges of the two tension toothed rings 3031. At this time, the beveled edges of the two tension toothed rings 3031 contact and squeeze each other, causing the tension disk 303 to move to one side and squeeze the tension top spring 3041 until the tension toothed ring 3031 of the released fixed roller 302 rotates one tooth angle, and the tension top spring 3041 is released again. At this time, the tension of the grey cloth will be released to prevent the grey cloth from being damaged due to the continuously increasing tension. Thereafter, the conveying component will repeat the above steps to realize the conveying and tension control of the grey cloth.

[0034] In another embodiment, the cross-sectional shapes of the tension disc 303 and the control disc 304 are both regular polygons, and an inner part of the mounting seat b301 is provided with a track groove 3011. The tension disc 303 and the control disc 304 are inserted into the track groove 3011. The track groove 3011 can limit the movement trajectories of the tension disc 303 and the control disc 304, so that the tension disc 303 and the control disc 304 will not be skewed or distorted during movement, resulting in the device being stuck and failing, and the use is stable.
