Description

Technical Field

[0001] The invention relates to the technical field of optical detection, in particular to a water-less and salt-free loose fiber dyeing machine. Background Art

[0002] In the low-water and salt-free loose fiber dyeing machine, optical inspection of the dyeing solution is an important step. The main purpose is to ensure the quality and consistency of dyeing. The color of the dye solution is monitored in real time by optical sensors, and the proportion of dyes can be adjusted in time to ensure that the color of the final product meets the expected standards. This is essential for producing high-quality and consistent products. Optical inspection can help detect possible unevenness in the dyeing process, such as local color is too dark or too light, so that measures can be taken to correct it in time to avoid color differences in the finished product. By analyzing the optical properties of the dye solution, the absorption of the dye can be evaluated, the amount of dye can be optimized, waste can be reduced, and costs can be reduced. By detecting and optimizing the dye solution, the use of dye solution can be reduced, thereby ensuring that the amount of process water and salt-containing dyes used in the dyeing machine is small.

[0003] The existing detection mechanism of the low-water and salt-free loose fiber dyeing machine has poor accuracy in detecting the color of the dye solution when performing optical detection on the dye solution, which easily affects the subsequent addition of dyes to the dye solution and reduces the dyeing effect on the loose fibers.

[0021] Beneficial effects of the present invention:

[0022] 1. The present invention can centrifugally dye the loose fibers by arranging a dyeing mechanism. After the dye liquid enters the inner cavity of the mesh cylinder, the output shaft of the first motor drives the rotating column to rotate through the small gear and the large gear, and the rotating column drives the inner cylinder and the mesh cylinder to rotate synchronously, so that the loose fibers fixed on the loose fiber holder are in uniform contact with the dye liquid, and the dye liquid dyes the loose fibers. The dyed dye liquid flows back to the bottom of the inner cavity of the tank through the through hole and enters the drain pipe. When the dye liquid needs to be discharged, the drain valve is opened.

[0023] 2. The present invention can facilitate the extraction of external dye liquid and dye liquid inside the dyeing mechanism by providing a liquid extraction mechanism. When extracting external dye liquid, the liquid pump extracts the externally stored dye liquid through the three-way electric valve and the liquid adding pipe, and the dye liquid enters the liquid outlet mechanism through the first bend pipe, the bypass pipe and the second bend pipe. When extracting the dye liquid inside the dyeing mechanism, the three-way electric valve is controlled to connect the liquid pump and the discharge pipe, and the liquid pump extracts the dye liquid inside the tank body through the discharge pipe.

[0024] 3. The present invention can perform optical detection on the dye liquid by setting an optical detection mechanism. When the dye liquid is inspected, the liquid outlet solenoid valve and the liquid inlet solenoid valve are opened, and the dye liquid discharged from the first elbow enters the sample container through the liquid inlet solenoid valve and flows back to the second elbow through the liquid outlet solenoid valve. When the dye liquid is inside the sample container, the heating ring heats the dye liquid, the first temperature sensor detects the temperature of the dye liquid, and controls the heating temperature according to the detected temperature, so that the temperature of the dye liquid inside the sample container is the same as the temperature of the dye liquid inside the tank body, avoiding the influence of temperature error on the detection accuracy. The light emitted by the light source is focused by the focusing lens and irradiated into the dye liquid inside the sample container, and the dye liquid transmits The light is decomposed into monochromatic light of different wavelengths by a monochromator. The monochromatic light is detected by a detector, and the optical signal is converted into an electrical signal. The detector is electrically connected to a signal processing unit. The signal processing unit amplifies, filters and digitally processes the electrical signal output by the detector to obtain the light intensity value at each wavelength, converts the light intensity value of each wavelength into color coordinates, calculates the color parameters of the dye solution, and transmits the color parameters to the controller. When the color concentration is too high, water is extracted through a liquid pump, a three-way electric valve and a liquid adding pipe. When the color concentration is too low, the dye tank and the metering pump are started to quantitatively add liquid dye to the mixing tank so that the color of the dye solution is kept within the set range.

[0025] 4. The present invention can perform secondary mixing on the dye liquid by arranging a liquid discharge mechanism, so that the dye in the dye liquid is evenly mixed, and liquid dye can be added to the dye liquid to change the color of the dye liquid. The dye liquid discharged from the second bent pipe enters the bottom of the inner cavity of the mixing tank through the connecting pipe, and the output shaft of the second motor drives the rotating rod to rotate. During the rotation of the rotating rod, the cross bar, the first mixing rod, the second mixing rod and the support rod are synchronously driven to rotate to stir and mix the dye liquid. During the rotation of the cross bar, the sliding ring is driven to shake up and down, and the spring and the support ring support the shaking sliding ring and the cross bar to facilitate the resetting of the cross bar. The cross bar drives the first mixing rod and the second mixing rod to rotate, and the support rod supports the rotating second mixing rod. The movement trajectory of the second mixing rod and the first mixing rod is changed during the rotation, thereby increasing the stirring and mixing effect, and the mixed dye enters the inner cavity of the liquid discharge tank through the discharge hole and enters the reflux mechanism.

[0026] 5. The present invention can facilitate the sealing of the top of the dyeing mechanism to prevent leakage of dye liquid by providing a sealing mechanism. During the operation of the sealing mechanism, the piston rod of the second cylinder drives the moving frame and the connecting frame to move, so that the tank cover moves to the bottom of the tank body, and then the piston rod of the first cylinder moves downward to cover the tank cover on the top of the tank body to seal it. During the movement of the tank cover, the sliding rod is driven to slide on the connecting frame to ensure stable movement of the tank cover.

[0027] 6. The present invention can heat and reflux the dye liquid by setting a reflux mechanism, thereby improving the dyeing effect of the dye liquid on the loose fibers. The dye liquid enters the inner cavity of the reflux pipe and contacts the surface of the heating pipe under the guidance of the conical head. The electric heating pipe and the heat conducting sheet heat the heating pipe and the dye liquid. The heated dye liquid enters the inner cavity of the mesh cylinder through the second liquid outlet hole and the first liquid outlet hole. The second temperature sensor detects the temperature of the dye liquid, and the detection data is transmitted to the controller. The controller controls the operation of the electric heating pipe according to the preset temperature to make the temperature of the dye liquid reach the preset value.

The dyed dye liquid flows back to the bottom of the inner cavity of the tank body 101 through the through hole 112 and enters the drain pipe 206.

The liquid pump 201 extracts the dye liquid inside the tank body 101 through the drain pipe 206, and flows back to the inner cavity of the dyeing mechanism 100 through the liquid discharge mechanism 400 and the reflux mechanism 600 to avoid the precipitation of the dye in the dye liquid.

[0059] When the dye solution is detected, the liquid outlet solenoid valve 303 and the liquid inlet solenoid valve 307 are opened, and the dye solution discharged from the first bend pipe 205 enters the sample container 302 through the liquid inlet solenoid valve 307, and flows back to the second bend pipe 204 through the liquid outlet solenoid valve 303. When the dye solution is inside the sample container 302, the heating ring 308 heats the dye solution, and the first temperature sensor 311 detects the temperature of the dye solution and controls the heating temperature according to the detected temperature, so that the temperature of the dye solution inside the sample container 302 is the same as the temperature of the dye solution inside the tank body 101, so as to avoid the temperature from affecting the detection accuracy. The light emitted by the light source 305 is focused by the focusing mirror 304 and irradiated into the dye solution inside the sample container 302. The light transmitted by the dye solution is decomposed into monochromatic light of different wavelengths by the monochromator 309. The monochromatic light is detected by the detector 310, and the optical signal is converted into an electrical signal. The detector 310 is electrically connected There is a signal processing unit, which amplifies, filters and digitally processes the electrical signal output by the detector 310 to obtain the light intensity value at each wavelength, converts the light intensity value at each wavelength into color coordinates, calculates the color parameters of the dye solution, and transmits the color parameters to the controller 102. When the color concentration is too high, water is extracted through the liquid pump 201, the three-way electric valve 202 and the liquid adding pipe 208. When the color concentration is too low, the dye tank 407 and the metering pump 408 are started to quantitatively add liquid dye to the mixing tank 402 so that the color of the dye solution is kept within the set range. When it is necessary to clean the inside of the sample container 302, the cleaning solenoid valve 306 is connected to an external cleaning device, and the cleaning water enters the sample container 302 to rinse the produced dye. The flushing sewage is discharged through the cleaning solenoid valve 306 to avoid residual impurities in the sample container 302 affecting the detection accuracy.
