Full-automatic dye mixing device for printing and dyeing mill

Abstract

The invention discloses a full-automatic dye mixing device for a printing and dyeing mill, relates to the field of full-automatic dye mixing of the printing and dyeing mill, and solves the problem that the existing dye mixing device for the printing and dyeing mill is difficult to mix by mixing supercritical fluid while stirring through a supercritical fluid mixing assembly in actual use. The problems that dye is stirred and mixed by driving a stirring rod through a motor, the mixing time is relatively long, the condition of non-uniform mixing possibly occurs, and when stirring blades are adopted for stirring and initial rotation, the contact resistance between the stirring blades and materials is relatively large, so that the load during initial starting of the motor is relatively large, and the service life of the motor is shortened are solved. The stirring blades are rotated after the motor is started, and the situation that the service life of the motor is shortened due to the fact that the load is large when the motor is initially started is avoided.

Description

Technical Field

[0001] The invention relates to the field of full-automatic dye mixing in a printing and dyeing factory, and in particular to a full-automatic dye mixing device used in a printing and dyeing factory. Background Art

[0002] Dyes are substances that can color fibers and other materials. They are divided into two categories: natural and synthetic. Dyes are colored substances, but colored substances are not necessarily dyes. Dyes are substances that can attach certain colors to fibers and are not easy to fall off or change color. Dyes are usually soluble in water, and some dyes require mordants to make the dyes adhere to the fibers. Archaeological data show that dyeing technology has a history of more than 5,000 years in India and the Middle East. At that time, dyes came from animals, plants or minerals and were rarely processed. In 1856, Perkin invented the first synthetic dye, horsetail purple, which led to a new discipline in organic chemistry, dye chemistry. In the 1950s, Pattee and Step Hen discovered that dyes containing dichloro-isotriazine groups bonded with hydroxyl groups on fibers under alkaline conditions, marking the development of dyes to color fibers from physical processes to chemical processes, and ushered in the synthetic application period of reactive dyes. Dyes are no longer limited to the dyeing and printing of textiles. They are used in many sectors such as paints, plastics, leather, optoelectronic communications, and food.

[0003] Dyes are indispensable supplies in printing and dyeing factories. When used, dyes are mostly dissolved in water in liquid form for easy use. Therefore, the dyes need to be mixed. Most of the existing dye mixing devices in printing and dyeing factories only use a motor to drive a stirring rod to stir and mix the dyes. Not only is the mixing time long, but uneven mixing may also occur. In order to improve the stirring effect, stirring blades are also used for stirring. However, when the stirring blades rotate initially, the contact resistance with the material is large, which makes the load of the motor large at the initial startup, reducing the service life of the motor.

When the rotating plate 219 moves, the rotating shaft 232 can be driven to rotate in the driven hollow rod 209. Then the stirring blade 216 can be rotated, thereby achieving the effect of changing the mixing resistance of the stirring blade 216 and avoiding damage to the motor. After the electric push rod 231 retracts, the pulling spring 217 drives the stirring blade 216 to reset through the fixed block 218. Embodiment 2

When the active hollow rod 205 rotates, the active hollow stirring rod 207 can be driven to rotate. At the same time, the active hollow rod 205 rotates When rotating, the driven hollow rod 209 will be driven to revolve through the second sealed bearing 208. When the driven hollow rod 209 revolves, it can rotate along the large bevel gear 212 on the bevel gear fixing plate 213 through the small bevel gear 211. When the driven hollow rod 209 rotates, it can drive the driven hollow stirring rod 210 to rotate, so that when the active hollow stirring rod 207 and the driven hollow stirring rod 210 mix the dye raw materials, the supercritical fluid is mixed with the dye. The supercritical fluid is supercritical carbon dioxide. Supercritical carbon dioxide has good diffusivity and solubility, and can quickly penetrate into the dye particles to promote its uniform dispersion. By setting the device mounting seat 7, the function of facilitating the support of the dye mixing mounting shell 1 is achieved, so that the PLC controller 8 can achieve the function of fully automatic mixing. By setting the one-way valve 9, the function of preventing the dye from entering the active hollow stirring rod 207 and the driven hollow rod 209 is achieved.

[0037] Step 3: After the driving motor 214 is started, the electric push rod 231 drives the push plate 230 to rise. When the push plate 230 rises, it also drives the pull rod 227 to rise. After the pull rod 227 rises, the pull rod 227 drives the second movable bearing 226 to rise along the pull slide 229 by pulling the slide plate 228. When the second movable bearing 226 rises, the second movable bearing 226 also drives the pull plate 225 to rise. When the pull plate 225 rises, the first movable bearing 221 can be driven by the pull rope 222 to pass through the pull groove 229. When the over-limit sliding plate 223 moves along the limiting sliding groove 224, the second movable bearing 226 can drive the rotating plate 219 to move through the linkage rope 220. When the rotating plate 219 moves, it can drive the rotating shaft 232 to rotate in the driven hollow rod 209, and then the stirring blade 216 can rotate, thereby achieving the effect of changing the mixing resistance of the stirring blade 216 and avoiding damage to the motor. After the electric push rod 231 retracts, the pulling spring 217 drives the stirring blade 216 to reset through the fixed block 218.

[0038] Step 4: By setting up a detection discharge pipe 501 and a detection discharge valve 502, the detection discharge valve 502 is started by the PLC controller 8, and the mixed dye in the dye mixing installation shell 1 is input into the small detection box 503. When a certain liquid level is reached in the small detection box 503, the liquid level sensor 506 controls the detection discharge valve 502 to be closed through the PLC controller 8, and then the quality of the dye is detected by the turbidity sensor 504 and the density sensor 505. When the quality is qualified, the PLC controller 8 orders the detection discharge valve 502 and the dye discharge valve 13 to be opened, so that the qualified dye is discharged through the dye discharge pipe 12.

[0039] Step 5: The temperature, pH, conductivity and pressure in the dye mixing installation housing 1 are respectively detected by the temperature sensor 401, the pH sensor 402, the conductivity sensor 403 and the pressure sensor 404. The PLC controller 8 automatically adjusts the speed of the drive motor 214, the heating temperature of the electric heater 405, and the opening of the gas exhaust valve 11 according to the temperature, pH, conductivity and pressure data, and dynamically adjusts the mixing speed, temperature and pressure of the mixture to ensure the best mixing effect.

[0040] Step six: by setting up a detection discharge pipe 501 and a detection discharge valve 502, the detection discharge valve 502 is started by the PLC controller 8, and the mixed dye in the dye mixing installation shell 1 is input into the small detection box 503. When a certain liquid level is reached in the small detection box 503, the liquid level sensor 506 controls the detection discharge valve 502 to be closed through the PLC controller 8, and then the quality of the dye is detected by the turbidity sensor 504 and the density sensor 505. When the quality is qualified, the PLC controller 8 orders the detection discharge valve 502 and the dye discharge valve 13 to be opened, so that the qualified dye is discharged through the dye discharge pipe 12.

[0041] Step seven: When the quality of the dye is unqualified, the PLC controller 8 commands the detection discharge valve 502, the reflux suction pump 601, the reflux suction pipe 602 and the infusion stop valve 604 in the reflux inlet pipe 603 to be opened, so that the unqualified dye can enter the reflux inlet pipe 603 through the reflux suction pipe 602 under the action of the reflux suction pump 601, and the reflux inlet pipe 603 inputs the unqualified dye into the dye mixing installation shell 1 for re-mixing.
