Description

Technical Field

[0001] The utility model relates to the field of textile equipment, and more specifically, to a cloth quality inspection device. Background Art

[0002] Cloth quality inspection is an important link in the textile production process. It ensures that the quality of the cloth meets the specified standards, thereby guaranteeing the quality and safety of the final product. The main purpose of cloth inspection is to detect defects on the cloth, such as holes, foreign hairs, dirt, etc. The existing cloth inspection is to pass the cloth in front of workers. After the workers find the defects on the cloth, they make marks for subsequent remedial treatment of the defects. In order to better detect the defects, workers will place a light source above the cloth to illuminate the cloth. However, in the form of lighting from above the cloth, it is difficult to detect dirt and foreign hairs on the back of the cloth. For example, when inspecting thick cloth such as carpets and blankets, it is also difficult to detect damage on the back of the cloth. Content of the Utility Model

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality" means two or more, unless otherwise specifically defined.

[0031] Embodiment:

[0032] A fabric quality inspection device, the fabric quality inspection device includes a feeding rack 1, a quality inspection device 2 and a winding device 3; the fabric enters the fabric inspection device through the feeding rack 1, and after the fabric is inspected, it enters the winding device 3 to complete the winding of the fabric; the fabric is pulled through the quality inspection device 2 to complete the quality inspection. It further includes a deviation rectifying device 4. When the fabric entering the winding device 3 deflects, the deviation rectifying device 4 compensates to make both ends of the wound fabric flat.

[0033] The quality inspection device 2 includes a mounting rack 20 and an inspection table 21. The inspection table 21 is arranged on the top of the mounting rack 20, and the inspection table 21 is inclined; when the fabric enters the inspection table 21, the inclined inspection table 21 gives the inspector a better working angle, enabling them to timely detect defects on the fabric.

[0034] The feeding rack 1 is connected to the mounting rack 20; the feeding rack 1 includes a column 11 and a crossbeam 12; the crossbeam 12 is arranged on the top of the column 11; a crossbar 13 and a first guide roller 14 are arranged on the crossbeam 12; the crossbar 13 is a cylindrical crossbar 13 and is fixedly connected to the crossbeam 12. A second guide roller 15 is arranged on the column 11. The fabric passes above the first guide roller 14 and the crossbar 13, bypasses below the second guide roller 15, and then enters the fabric inspection machine upward. The first guide roller 14 and the second guide roller 15 realize the longitudinal tension and pulling of the fabric. The crossbar 13 plays a role in initially flattening the curled and folded fabric. Specifically, when there is a fold on the fabric, the crossbar 13 cannot rotate, and the crease will be initially flattened when the fold passes over the crossbar. After flattening the fabric, it is beneficial to inspect the fabric when the fabric passes through the light source box 23.

[0035] Above the inspection table 21, there is a feeding roller 22; the feeding roller 22 is driven by a motor to achieve autonomous rotation. After the fabric bypasses the lower part of the second guiding roller 15, it enters the inspection table 21 through the feeding roller 22. A light source box 23 is arranged on the inspection table 21. A lamp tube is arranged in the light source box 23. When the fabric passes above the light source, the light below passes through the fabric and is transmitted, and the defect points on the fabric can be easily observed, which is convenient for the staff to mark.

[0036] Preferably, a white paint layer is arranged on the inner surface of the light source box 23, and a reflector 232 is arranged on the lamp tube, and the reflector 232 faces the bottom of the light source box 23; through the above scheme, the lamp tube does not directly irradiate the fabric with light; instead, it is diffusely reflected by the white paint layer in the light source box 23. When the fabric passes through the light source box 23, the light can be more evenly transmitted from the fabric, avoiding misjudgment of fabric defects due to high local light intensity.

[0037] In a possible embodiment, a transparent cover plate 231 is arranged on the light source box 23; the transparent cover plate 231 can be made of glass or acrylic. The cover plate made of transparent material can project light well. After the worker finds the defect point and needs to mark it, the marking method generally uses stickers. After adding the transparent cover plate 231, it is convenient for the worker to stick stickers on the defect point. Preferably, a white coating is arranged on the side of the glass cover plate facing away from the fabric. After the lamp tube in the box irradiates the glass cover plate, the light can also be evenly distributed.

[0038] In a possible embodiment, the quality inspection device 2 further includes a lamp shade 24; the lamp shade 24 is arranged above the inspection table 21. A lamp tube is arranged in the lamp shade 24. The lamp tube irradiates the upper part of the fabric from above. When the fabric is thick or it is necessary to focus on inspecting the surface of the fabric, the lamp tube in the lamp shade 24 is turned on to irradiate the upper surface of the fabric. The inspection of the upper surface of the fabric is realized. Preferably, the inner surface of the lamp shade 24 has a white paint layer.

[0039] A tensioning device 25 is further provided on the inspection table 21. The tensioning device 25 includes a set of corresponding mounting seats 255. The mounting seats 255 are sequentially provided with a first tensioning member, a leveling roller 253, and a second tensioning member along the moving direction of the fabric; the first tensioning member includes a first cross bar 251; the first cross bar 251 is fixedly connected to the mounting seat 255; the leveling roller 253 is connected to the mounting seat 255 through a wheel bearing; one end of the leveling roller 253 is provided with a leveling wheel 2531; the leveling wheel 2531 is driven by a motor to drive the threaded wheel to rotate. The second tensioning member includes a tensioning roller 254. During use, the fabric bypasses the lower part of the first cross bar 251, passes above the leveling roller 253, enters below the tensioning roller 254, and is finally sent to the winding device 3. Here, the fabric is pressed down by the first cross bar 251 and the tensioning roller 254, which can increase the friction between the fabric and the leveling roller 253 and is beneficial to leveling the fabric.

[0040] Preferably, a threaded wire is wound around the leveling roller 253, and the winding directions of the threaded wires at both ends of the leveling roller 253 are opposite. During use, when the fabric passes through the leveling roller 253, under the action of the threaded wire, the fabric is pulled to both sides, and the wrinkles of the fabric are leveled through the above scheme.

[0041] In a possible embodiment, the first tensioning member further includes a second cross bar 252; the second cross bar 252 is fixedly connected to the mounting seat 255, and the second cross bar 252 is arranged above the first cross bar 251. When the fabric bypasses the lower end of the second cross bar 252 and contacts the leveling roller 253, since the second cross bar 252 is above the first cross bar 251, the contact area between the fabric and the leveling roller 253 becomes smaller and the friction becomes smaller, so that the fabric can pass more smoothly. The user can select to pass through the first cross bar 251 or the second cross bar 252 according to the type and wrinkle degree of the fabric.

[0042] The winding device 3 includes a winding frame 30; a winding roller is provided on the winding frame 30; a fixing groove 311 is provided on the winding frame 30; the winding roller includes a shaft roller and a roller seat 321; a seat hole 322 is provided on the roller seat 321; the winding roller is connected to the winding frame 30 by bolt - connecting the seat hole 322 and the fixing groove 311. There are two winding rollers on the winding frame 30, namely a first winding roller 31 and a second winding roller 32. When winding the fabric, a central shaft is needed. Place the central shaft between the first winding roller 31 and the second winding roller 32. After guiding the fabric to the central shaft, the winding roller rotates. Under the action of friction, the central shaft starts to rotate, and during the rotation process, the fabric is wound along the central shaft. The sizes of the central shafts used for different fabrics are different, the winding lengths are different, the thicknesses of the fabrics are different, and the sizes of the wound rolls are different. The above factors require adjusting the distance between the first winding roller 31 and the second winding roller 32. In this embodiment, the bolts can be loosened, the positions of the first winding roller 31 and the second winding roller 32 can be adjusted to appropriate positions, and after the bolts are set at appropriate positions in the fixing groove 311, the bolts can be tightened.

[0043] The winding device 3 further includes a driving mechanism, and the driving mechanism is arranged on the winding frame 30. The driving mechanism includes a driving wheel 341, a tensioning mechanism 343 and a shaft roller wheel 342; the tensioning mechanism 343 includes a tensioning wheel 3433. The shaft roller wheel 342 is connected to the first winding roller 31, and the driving wheel 341, the tensioning wheel 3433 and the shaft roller wheel 342 are connected by a transmission belt. The driving wheel 341 is driven by a motor and drives the shaft roller wheel 342 to rotate through the transmission belt, and then drives the first winding roller 31 to rotate.

[0044] Preferably, the tensioning mechanism 343 further includes an adjusting mechanism. The adjusting mechanism includes a set of oppositely arranged adjusting seats 3434; a screw rod 3431 hole and a guide rod 3432 hole are provided on the adjusting seat 3434. The adjusting mechanism further includes a screw rod 3431 and a guide rod 3432; both ends of the screw rod 3431 are respectively connected to the screw rod 3431 hole through bearings; both ends of the guide rod 3432 are respectively fixedly connected to the guide rod 3432 hole. The adjusting seat 3434 is fixed to the winding frame 30. It further includes an adjusting block. The adjusting block includes an adjusting part and a guiding part; the guiding part and the adjusting part are fixedly connected; the guiding part is slidably connected to the guide rod 3432. The adjusting part is in threaded cooperation with the screw rod 3431. When the position of the first winding roller 31 on the winding frame 30 changes, the transmission belt will become loose or taut, resulting in problems such as the transmission belt coming off or being unable to adjust the position of the winding roller. By setting the tensioning mechanism 343, the problems of the transmission belt coming off or being unable to adjust the winding device 3 can be solved. Specifically, when the transmission belt is loose, rotate the screw rod 3431 to make the tensioning wheel 3433 move away from the shaft roller wheel 342 to achieve the purpose of tensioning the transmission belt. Conversely, after loosening the transmission belt, the winding roller can be adjusted smoothly.

[0045] Preferably, a turntable 3435 is provided at one end of the lead screw 3431, and the lead screw 3431 can be rotated better through the turntable 3435.

[0046] Preferably, a baffle mechanism 33 is further provided on the winding frame 30. A slide rail is provided on the winding frame 30. The baffle mechanism 33 includes a slide seat 331, a cantilever 332 and a baffle 333. The slide seat 331 is slidably connected to the slide rail, and the slide seat 331 can be fixed to the slide rail by screws. One end of the cantilever 332 is fixedly connected to the top of the slide seat 331; the other end is slidably connected to the baffle 333. Similarly, the baffle 333 can be fixed to the cantilever 332 by screws. A set of correspondingly arranged baffle mechanisms 33 are provided on the winding frame 30. The cloth roll is arranged between the two baffle mechanisms 33. When the cloth roll rotates on the first winding roller 31 and the second winding roller 32, the positions of the cloth roll can be kept relatively stable through the two baffle mechanisms 33, avoiding the problem that the two ends of the curled cloth are uneven.

[0047] Preferably, a conical portion 3331 is provided at the lower end of the baffle 333. The conical portion 3331 is located at the central position of the first winding device 3 and the second winding device 3. When there is less cloth on the central axis, the conical portion 3331 can play a role in resisting. Different cloth rolls have different widths. By adjusting the position of the slide seat 331 on the slide rail, the baffle mechanism 33 can be located at a suitable position to match cloth rolls of different widths. Adjusting the position of the baffle 333 on the cantilever 332 can adapt to cloth rolls with different central axes.

[0048] Preferably, a third guide roller 35 is provided below the winding roller. The cloth passes upward between the first winding roller 31 and the second winding roller 32 under the tension roller 254 and is wound around the central axis.

[0049] The deviation rectifying device 4 includes a base, on which a track 41 and a threaded rod 42 are provided. Rollers are provided below the winding frame 30; the rollers are matched with the track 41. The winding frame 30 can move left and right on the base through the rollers. The threaded rod 42 is driven to rotate by a motor. Preferably, the threaded rod 42 is driven to rotate by a stepper motor that can rotate forward and backward. A moving block 43 is provided below the winding frame 30, and the moving block 43 is fixedly connected to the winding frame 30. A threaded hole matching the threaded rod 42 is provided on the moving block 43. When the threaded rod 42 rotates, the moving block 43 drives the winding frame 30 to move left and right.

[0050] The deviation rectifying device 4 further includes a deviation rectifying sensor, which is arranged on the cloth traveling path; specifically, the deviation rectifying device 4 is arranged between the third guide roller 35 and the tension roller 254. When the deviation rectifying sensor senses that the cloth deflects, the stepper motor is controlled to rotate through the controller, and then the winding device 3 is driven to move left and right for compensation, avoiding the cloth deviating from the central axis during the winding process.

[0051] Those skilled in the art should be aware that the motor drive mentioned in this embodiment can be independently implemented by a motor drive, or can be achieved by driving a smaller number of motors simultaneously through transmission forms such as chains, belts, and timing belts.

[0052] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
