Description

Technical Field

[0001] The invention relates to the technical field of fiber content detection, and in particular to a spectrum measuring device and a method for measuring the fiber content of a blended fabric. Background Art

[0002] According to the working principle of modern spectrometers, spectrometers can be divided into two categories: classical spectrometers and new spectrometers. Classical spectrometers are based on the principle of spatial dispersion; new spectrometers are based on the principle of modulation. Classical spectrometers are all slit spectrometers. Modulation spectrometers are non-spatial spectrometers, which use circular apertures to enter the light. According to the spectroscopic principle of dispersion components, spectrometers can be divided into: prism spectrometers, diffraction grating spectrometers and interference spectrometers.

[0015] To achieve the above object, the present invention provides the following technical solution: a method for determining the fiber content of a blended fabric, comprising the following steps: First, the motor in the detection shell drives the cloth release roller to release the stored blended fabric, and the cloth collection roller rewinds the blended fabric after passing the spectrometer onto the cloth collection roller for storage. During this process, the blended fabric will also contact the unwinding roller 1 and the unwinding roller 2 on both sides of the spectrometer, and the coordination components at both ends of the cloth collection roller and the cloth release roller will simultaneously drive the unwinding roller 1 and the unwinding roller 2 to rotate. After the cloth release roller releases the blended fabric, the blended fabric will first contact the unwinding roller 2 on one side of the cloth release roller, and the unwinding roller 2 will rotate to push the blended fabric to the bottom of the spectrometer. During this process, the unwinding slide 1 and the unwinding slide 2 surrounding the surface of the unwinding roller 1 and the unwinding roller 2 will slide along the surface of the unwinding component , so that each unfolding slide plate 1 and unfolding slide plate 2 gradually slide to both sides in turn, and the unfolding slide plate 1 and unfolding slide plate 2 on the unfolding roller 1 and unfolding roller 2 will use friction to unfold the blended fabric on the unfolding roller 1 and unfolding roller 2, so that the wrinkles on the blended fabric are flattened; when the blended fabric passes over the unfolding roller 2, it will be clamped by the upper extrusion plate and the lower extrusion plate in the limiting track, and the driving component in the limiting shell cover drives each sliding column to slide, so that each upper extrusion plate and the lower extrusion plate clamp the blended fabric between the upper extrusion plate and the lower extrusion plate, so as to prevent the two sides of the blended fabric from rebounding and wrinkling due to the characteristics of the material, so that the blended fabric can arrive flat under the spectrometer for detection.

[0016] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The motor in the detection shell drives the cloth-releasing roller to drop the stored blended fabric, and the blended fabric after passing through the spectrometer is rewound onto the cloth-collecting roller for storage through the cloth-collecting roller. The blended fabric under the spectrometer is unfolded and flattened to both sides through the unfolding roller 1 and the unfolding roller 2. After the blended fabric is flattened, the spectrometer can ensure uniform irradiation and scanning of the sample, thereby reducing signal fluctuations caused by sample unevenness and improving the accuracy and reliability of the measurement results. The upper and lower extrusion plates are driven by the driving assembly to clamp and push the blended fabric in the middle, and the two sides of the blended fabric are limited to prevent the blended fabric from rebounding and wrinkling after passing through the unfolding roller 2. The tension of the blended fabric between the unfolding rollers can be stably controlled to prevent the material from forming wrinkles due to elastic rebound during the unfolding process.

[0017] 2. The return spring compressed in the installation slide groove will push the limit slide bars on both sides of the limit slider to slide along the limit slide groove under the reaction force, so that the expansion slide plate 1 and the expansion slide plate 2 on the expansion roller 1 are always in contact with the surface of the annular inclined blocks at both ends, so that the expansion slide plates 1 and the expansion slide plates 2 on the surfaces of the expansion rollers 1 and 2 rotate and gradually slide and expand to both sides along the installation slide groove. Each expansion slide plate 1 and the expansion slide plate 2 pushes the blended fabric to both sides in turn to expand it, so that it is evenly distributed along the surface of the expansion rollers 1 and 2, avoiding material accumulation or unevenness, ensuring the uniformity of the blending process, improving the accuracy and efficiency of the blending process, and ensuring the consistency and quality of the final product.

[0018] 3. By driving the transmission belt to slide along the T-shaped slide groove opened in the limit shell, the sliding column installed on the other side of the transmission belt is driven to slide along the sliding cavity. The limit slide column 1 and the limit slide column 2 both move along the limit track. The upper extrusion plate and the lower extrusion plate will automatically open and close to clamp the side of the blended fabric and move. The automatic opening and closing clamping device can reduce manual intervention. Through the function of automatic clamping and limiting, it can ensure that the blended material is stably maintained within the specified range during the processing, avoiding the deviation or unevenness of the material during processing.

[0023] The present invention will be further described below in conjunction with the embodiments.

A transmission component is arranged in the limit shell 302, and sliding columns 303 are installed on the transmission component at intervals. The transmission component can drive the sliding column 303 to slide in the limit shell 302. An upper extrusion plate 304 is slidably connected to one side of the column 303, and a lower extrusion plate 305 is arranged below the upper extrusion plate 304. The upper extrusion plate 304 and the lower extrusion plate 305 are symmetrically slidably connected in the sliding column 303. An upper and lower set of limiting rails are provided on the limiting shell 302. The upper extrusion plate 304 is slidably connected in the upper limiting rail, and the lower extrusion plate 305 is slidably connected in the lower limiting rail, so that each upper extrusion plate 304 and the lower extrusion plate 305 clamp the two sides of the blended fabric 203 for pushing.

[0025] Specifically, the motor in the detection shell 100 drives the cloth placing roller 202 to place the stored blended fabric 203, and the cloth collecting roller 201 rewinds the blended fabric 203 after passing through the spectrometer onto the cloth collecting roller 201 for storage. During this process, the blended fabric 203 will also contact the unrolling roller 1 204 and the unrolling roller 2 205 on both sides of the spectrometer, and the coordination components at both ends of the cloth collecting roller 201 and the cloth placing roller 202 will simultaneously drive the unrolling roller 1 204 and the unrolling roller 2 205 to rotate. After the cloth placing roller 202 places the blended fabric 203, the blended fabric 203 will first contact the unrolling roller 2 205 on one side of the cloth placing roller 202, and the unrolling roller 2 205 will rotate to push the blended fabric 203 to the bottom of the spectrometer. During this process, the unrolling slide 1 206 and the unrolling slide 2 207 surrounding the surface of the unrolling roller 1 204 and the unrolling roller 2 205 will move along the surface of the unrolling component. The first and second unfolding slide plates 206 and 207 slide gradually to both sides in sequence, and the first and second unfolding slide plates 206 and 207 on the first and second unfolding rollers 204 and 205 use friction to spread out the blended fabric 203 on the first and second unfolding rollers 204 and 205, so that the wrinkles on the blended fabric 203 are flattened. After the blended fabric 203 passes over the second unfolding roller 205, it will be clamped by the upper extrusion plate 304 and the lower extrusion plate 305 in the limiting track, and the driving components in the limiting shell 302 drive each sliding column 303 to slide, so that each upper extrusion plate 304 and the lower extrusion plate 305 clamp the blended fabric 203 between the upper extrusion plate 304 and the lower extrusion plate 305, so as to prevent the two sides of the blended fabric 203 from rebounding and wrinkling due to the characteristics of the material, so that the blended fabric 203 can reach the bottom of the spectrometer smoothly for detection.

[0026] The motor in the detection outer shell 100 drives the cloth placing roller 202 to place the stored blended fabric 203, and the blended fabric 203 after passing through the spectrometer is rewound onto the cloth collecting roller 201 for storage by the cloth collecting roller 201, and the blended fabric 203 under the spectrometer is spread out and flattened to both sides by the unfolding roller 1 204 and the unfolding roller 205. After the blended fabric 203 is flattened, the spectrometer can ensure uniform irradiation and scanning of the sample, thereby reducing signal fluctuations caused by sample inhomogeneity and improving the accuracy and reliability of the measurement results. The upper squeezing plates 304 and the lower squeezing plates 305 are driven by the driving assembly to clamp and push the blended fabric 203 in the middle, and the two sides of the blended fabric 203 are limited to prevent the blended fabric 203 from rebounding and wrinkling after passing through the unfolding roller 205, and the tension of the blended fabric 203 between the unfolding rollers can be stably controlled to prevent the material from forming wrinkles due to elastic rebound during the unfolding process.

[0027] Example 2 Reference Figure 1-Figure 6, which is a second embodiment of the present invention, provides a spectrum measuring device, the unfolding component includes a mounting slot 208 that is arranged on the unfolding roller 1 204 at a circumferential interval, a limiting slider 209 is slidably connected in the mounting slot 208, and both sides of the limiting slider 209 are fixedly connected to the limiting slider 210, and both sides of the unfolding roller 1 204 are provided with limiting slots 211, and the limiting slots 211 are arranged on both sides of the inner wall of the mounting slot 208, and the lower surfaces of the unfolding slide plate 1 206 and the unfolding slide plate 207 are fixedly connected to the limiting slider 209, driving the unfolding slide plate 1 206 and the unfolding slide plate 207 to slide along the surface of the unfolding roller 1 204.

[0028] A return spring 212 is fixedly installed on one side of the limiting slider 209, and the other end of the return spring 212 is fixedly installed on the inner wall of the mounting slide groove 208. The second unfolding roller 205 is arranged the same as the unfolding roller 1 204. Both ends of the unfolding roller 1 204 are sleeved with an annular bevel block 213. One end of the unfolding slide plate 1 206 and the unfolding slide plate 207 are slidably connected to the surface of the annular bevel blocks 213 on both sides. The surface of the annular bevel blocks 213 is one high and one low, and the shape is annular. The side of the annular bevel block 213 away from the unfolding roller 1 204 is fixedly connected to a support frame 214, and the bottom end of the support frame 214 is fixedly connected to a mounting plate 215, and the lower surface of the mounting plate 215 is fixedly connected to the inner wall of the detection outer shell 100.

[0029] The coordination component includes a driving gear 216 fixedly mounted on one end of the cloth placing roller 202, a driven gear 217 meshing on one side of the driving gear 216, a motor fixedly mounted on one side of the driving gear 216, a rotating disk 218 fixedly mounted on the side of the driven gear 217 close to the unfolding roller 204, a belt 219 sleeved on the rotating disk 218, and a bevel gear 220 sleeved on the end of the belt 219 away from the rotating disk 218.

[0030] A bevel gear 221 is meshed above the bevel gear 1 220 . The top of the bevel gear 221 is rotatably connected to the bottom of the limiting shell 302 . One end of the bevel gear 1 220 is rotatably connected to a mounting bracket 222 . The lower surface of the mounting bracket 222 is fixedly connected to the mounting plate 215 .

[0031] Specifically, the motor installed on the inner wall of the detection shell 100 drives the driving gear 216 to rotate, and the cloth placing roller 202 on the other side of the driving gear 216 is pushed to rotate to place the blended fabric 203. While the driving gear 216 rotates clockwise, it drives the driven gear 217 meshing on one side to rotate counterclockwise, so that the unrolling roller 205 on one side of the driven gear 217 rotates at the same time. While the unrolling roller 205 rotates, it contacts the lower surface of the blended fabric 203, and the unrolling slide plates 1 206 and 207 on both sides of the surface of the unrolling roller 205 slide along the annular inclined blocks 213 at both ends at the same time. As the unfolding roller 205 rotates, the unfolding slide plate 1 206 and the unfolding slide plate 207 will be driven to rotate along the surface of the annular inclined block 213 at the same time, and slide from the high position of the annular inclined block 213 along the inclined surface to the low position. In this process, the return spring 212 compressed in the slide groove 208 will push the limit slide bars 210 on both sides of the limit slide block 209 to slide along the limit slide groove 211 under the reaction force, so that the unfolding slide plate 1 206 and the unfolding slide plate 207 on the unfolding roller 1 204 always contact and fit with the surfaces of the annular inclined blocks 213 at both ends. As a result, as the unfolding roller 205 rotates, the unfolding slide plate 206 and the unfolding slide plate 207 are always pressed against and fit with the surfaces of the annular inclined blocks 213 at both ends. 06 and the unfolding slide plate 207 will expand as they slide to both sides. When the unfolding slide plate 1 206 and the unfolding slide plate 207 are in the initial state, they are both located at the high position of the surface of the annular inclined block 213. Since the annular inclined block 213 resists the unfolding slide plate 1 206 and the unfolding slide plate 207, the return spring 212 in the installation slide groove 208 is in a compressed state. At this time, the corresponding ends of the unfolding slide plate 1 206 and the unfolding slide plate 207 on both sides are in a resisting fit. As the unfolding roller 1 204 and the unfolding roller 2 205 rotate, the unfolding slide plate 1 206 and the unfolding slide plate 207 gradually move from the high position of the annular inclined block 213 to the The unfolding slide plate 1 206 and the unfolding slide plate 207 on the surface of the unfolding roller 1 204 and the unfolding roller 205 gradually slide and unfold to both sides along the installation slide groove 208 while rotating, so that the corresponding ends of the unfolding slide plate 1 206 and the unfolding slide plate 207 are no longer in conflict with each other, so that the wrinkles on the surface of the blended fabric 203 are spread out, and this cycle is repeated. The belt 219 is respectively mounted on the rotating disk 218 and the bevel gear 1 220 at both ends. The rotation of the driven gear 217 can simultaneously drive the bevel gear 221 meshing above the bevel gear 1 220 to rotate, so that the driving component in the limiting shell 302 works.

The T-shaped slide groove 308 is composed of a wide channel and a narrow channel, presenting a T shape, the transmission belt 307 is slidably connected in the wide channel of the T-shaped slide groove 308, and the contact block 309 is slidably connected in the narrow channel of the T-shaped slide groove 308.

The driving drum 310 is provided with matching grooves 311 at intervals, which mesh with the contact block 309 on one side of the transmission belt 307. The lower surface of the driving drum 310 is fixedly connected to the top of the bevel gear 221, and the upper extrusion plate 304 and the lower extrusion plate 305 provided on the transmission belt 307 are driven to slide along the limiting track by the rotation of the driving drum 310.

A lifting slider 1 316 is slidably connected in the adjusting slot 315, and a lifting slider 2 317 is slidably connected to the end of the adjusting slot 315 away from the lifting slider 1 316. A limiting sliding column 1 318 is fixedly connected to one side of the lifting slider 1 316.

[0036] Specifically, the bevel gear 221 on the lower surface of the limit shell 302 rotates to drive the driving drum 310 to rotate. When the driving drum 310 rotates in the limit shell 302, it will mesh with the contact block 309 on one side of the transmission belt 307, driving the transmission belt 307 to slide along the T-shaped slide groove 308 provided in the limit shell 302, and driving the sliding column 303 installed on the other side of the transmission belt 307 to slide along the sliding cavity 306. The limit slide column 1 318 and the limit slide column 2 319 both move along the limit track. When the sliding column 303 drives the upper extrusion plate 304 and the lower extrusion plate 305 to rotate from the side to the blended fabric 203, the limit slide column 1 318 and the limit slide column 2 319 will slide from the running slide 312 to the inclined slide 313, and the symmetrical lifting slider 1 316 and the lifting slider 2 317 in the adjustment slide groove 315 begin to slide together, driving The upper squeezing plate 304 and the lower squeezing plate 305 clamp the side of the blended fabric 203. When the limiting slide post 1 318 and the limiting slide post 2 319 slide from the inclined slide 313 to the pushing slide 314, the lifting slide block 1 316 and the lifting slide block 2 317 in the adjustment slide 315 remain in position, and the upper squeezing plate 304 and the lower squeezing plate 305 clamp the side of the blended fabric 203 to move, so as to prevent the blended fabric 203 from being moved. When the upper extrusion plate 304 and the lower extrusion plate 305 move from the position of the lower extrusion plate 305 to the position of the upper extrusion plate 304 on the other side, the limiting slide 1 318 and the limiting slide 2 319 will move from the pushing slide 314 to the reverse inclined slide 313, driving the upper extrusion plate 304 and the lower extrusion plate 305 to gradually open, canceling the clamping limit on the side of the blended fabric 203, and performing reciprocating operation.

During this process, the blended fabric 203 will also contact the unwinding roller 1 204 and the unwinding roller 2 205 on both sides of the spectrometer. The coordination components at both ends of the cloth taking-up roller 201 and the cloth putting roller 202 will simultaneously drive the unwinding roller 1 204 and the unwinding roller 2 205 to rotate. After the cloth putting roller 202 puts down the blended fabric 203, the blended fabric 203 will first contact the unwinding roller 2 205 on one side of the cloth putting roller 202. The unwinding roller 205 rotates to push the blended fabric 203 to the bottom of the spectrometer. During this process, the surface of the unwinding roller 1 204 and the unwinding roller 2 205 is The unfolding slide plate 1 206 and the unfolding slide plate 2 207 will slide along the surface of the unfolding component, so that each unfolding slide plate 1 206 and the unfolding slide plate 2 207 will gradually slide to both sides in turn, and the blended fabric 203 on the unfolding roller 1 204 and the unfolding roller 2 205 will be spread out. After the blended fabric 203 passes over the unfolding roller 2 205, it will be clamped by the upper squeezing plate 304 and the lower squeezing plate 305 in the limiting track, and the driving component in the limiting shell 302 will drive each sliding column 303 to slide, so that each upper squeezing plate 304 and the lower squeezing plate 305 will clamp the blended fabric 203 between the upper squeezing plate 304 and the lower squeezing plate 305, so as to prevent the two sides of the blended fabric 203 from rebounding and wrinkling due to the characteristics of the material, so that the blended fabric 203 can arrive flat under the spectrometer for detection.
