The driving mechanism comprises a first gear 613 arranged at the end of a rotating screw rod 612, a transmission gear 614 in meshing transmission with the first gear 613 is arranged on the valve body 601, and a rack 615 in meshing transmission with the transmission gear 614 is arranged on the valve body 601 in a sliding manner. The pressure fluctuation in the distributed conveying pipeline is eliminated by arranging the specific pressure difference valve, and the pressure difference valve adjusts the pre-compression amount of the spring 611 by rotating the screw rod 612, so that the flow limiting plate 620 is adjusted in a flow limiting manner, different pressure difference adjustments are realized, the flexible adjustment can be performed according to the pressure of liquid conveyed in the conveying pipeline, and the conveying requirements of different dyes are met. Under the elastic expansion action of the positioning compression spring 619, the first positioning plate 608 and the second positioning plate 609 are tightly attached to the inner wall of the pressure difference chamber 602 in the pressure difference valve, so that the first positioning plate 608 and the second positioning plate 609 are conveniently fixed on the inner wall of the pressure difference chamber 602, wherein the restrictor plate 620 is connected with the first positioning plate 608 through the link mechanism 610, and under the action of the link mechanism 610, the restrictor plate 620 is limited, so that the upper and lower adjustment of the restrictor plate 620 by the rotating screw rod 612 is effectively avoided, the restrictor plate 620 rotates along with the rotation of the rotating screw rod 612, when the pressure difference valve performs pressure stabilization, when the liquid inlet main pipe 605 injects liquid into the pressure difference chamber 602, a part of the liquid is divided by the first bypass guide pipe 606 and enters the pressure difference chamber 602, the liquid flowing out of the first bypass guide pipe 606 is limited by the restrictor plate 620, when the liquid pressure of the first bypass guide pipe 606 changes, the liquid damping in the first bypass guide pipe 606 changes, and the liquid pressure in the liquid inlet main pipe 605 changes, so that the function of adjusting the pressure difference is achieved; the liquid pressure in the main liquid inlet pipe 605 is indirectly adjusted by adjusting the liquid pressure of the first bypass guide pipe 606, so that small-range micro adjustment of the liquid pressure in the main liquid inlet pipe 605 can be initiated when the liquid pressure in the first bypass guide pipe 606 is adjusted in a larger range, and the liquid pressure has higher sensitivity and is convenient for conveying to be accurately adjusted.

The working principle is as follows: after receiving calling information of insufficient dye liquor of the target storage tank 7 according to a control system in the upper computer 1, working personnel selects corresponding dye according to the dye liquor in the target storage tank 7 and the dye is contained in a charging basket in a centralized mode according to the set proportioning weight through a dye distribution system 9; after the charging bucket filled with the dye is conveyed to a specified material taking position by using a dye conveying device, the charging bucket on the material taking position is conveyed to a dissolution corner motor support in a dissolution cylinder by a manipulator 3 for clamping and positioning; then closing the dissolving cylinder and carrying out feeding operation; after the feeding operation is finished, the dissolving cylinder is opened, the manipulator 3 is used for grabbing the empty charging basket and sending the empty charging basket into the charging basket drying equipment for drying; closing the dissolving cylinder again, and carrying out automatic material dissolving operation on the dye according to a set dissolving process program; after the dye is dissolved, the dye dissolved in the dissolving tank is sent to a target dye vat by using a distributed conveying pipeline, and the distributed conveying pipeline and the dissolving tank are cleaned. According to the invention, the automatic preparation process is set to carry out automatic preparation on the reactive dye, so that the participation of personnel is greatly reduced, and direct damage to the health of operators is avoided; the method greatly improves the effect of dye dissolution preparation, ensures that the printing and dyeing product has better printing and dyeing quality, and has the characteristic of high working efficiency.
