The jet dry particle printing production system capable of printing fine patterns prints glaze on a ceramic tile blank through a glaze printer 20, then the jet printer 30 jets ink on the ceramic tile blank to print patterns, and then the glaze is printed on the ceramic tile blank, then the patterns are printed through jetting, the effect of the ink-jet patterns is clearer, then the dry particle printer 10 prints dry particles on the surface of the ink-jet patterns of the ceramic tile blank in a positioning manner, finally the dry particle distributing machine 60 spreads dry particle sheets on the ceramic tile blank, the obtained ceramic tile blank has rich decorative effect, besides the texture generated by the ink-jet printing patterns printed by the jet printer 30, the effect of printing the dry particles in the positioning manner of the dry particle printer 10 and the decorative effect of the surface dry particle sheets laid by the dry particle distributing machine 60 are also increased, the decorative means are enriched, different types of dry particles are printed by combining the dry particle printer 10, and the collocation of the different types of dry grain pieces that dry grain piece cloth machine 60 laid has realized that ceramic brick decoration is abundant in the decorative effect of same level, the decoration texture is clear fine and smooth, the abundant demand of the three-dimensional effect of different levels, in addition, through setting up feed back machine 5 is right the unnecessary dry grain that dry grain printer 10 printed on ceramic tile base surface is retrieved, then supplies to again dry grain printer 10 can realize the circulation of dry grain and recycle, effectively practices thrift manufacturing cost, can reduce the cost of labor, improves production efficiency, and the decorative effect of the ceramic brick that the preparation obtained is abundant, and the third dimension is strong.
The dry particle printer 10 prints glue on the limited area of the ceramic green brick through the glue applying unit 6, then the blanking unit prints dry particles on the limited area of the ceramic green brick printed with the glue, the dry particles can be positioned on the limited area with the glue, and the plurality of blanking boxes 1 are arranged in parallel right above the conveying belt 4 to print the dry particles on the green brick. Each blanking box 1 is uniformly divided into a plurality of blanking cavities 13 through partition plates 12, and the same or incompletely same dry particles can be put into each blanking cavity 13 according to production requirements; each blanking cavity 13 is inserted with an air inlet branch pipe 32, and when the air inlet branch pipe 32 injects air, dry particles of the corresponding blanking cavity 13 are ejected from the blanking pipe 11 under the driving of air flow and fall on green bricks of the conveying belt 4; each air inlet branch pipe 32 is provided with a switch control valve 33, so that whether each blanking box 1 is blanked (namely, which position point is controlled to be blanked) and which blanking box 1 to be blanked is which blanking cavity 13 is blanked (namely, what type of dry particle is controlled to be blanked), the corresponding air inlet branch pipe 32 is started to eject air only in the area where the dry particle needs to be distributed on the green brick in a plurality of blanking boxes 1 which are arranged side by side during working, the blanking box 1 corresponding to the area where the dry particle needs to be distributed does not eject air, the working process is similar to ink jet printing, so that the printing type positioning blanking dry particle is realized, a complex pattern with fine lines can be formed on the green brick, the efficiency of positioning blanking of the dry particle and the accuracy of distribution are effectively improved, the control is easy, and the equipment is simple; different from a plurality of blanking units which are arranged in the front and back direction along the conveying direction of the green bricks, a plurality of dry particle printing stations are not required to be arranged, and the green bricks can pass through one dry particle printing station, so that the production speed of the ceramic tiles is improved.
The blanking box 1 adopts the blanking hose 11, thereby can overcome the influence of the gap between the blanking box 1 to the printing continuity, all the blanking ends of the blanking hose 11 of the blanking box 1 can be arranged on the blanking frame 41 closely and side by side, thereby the position points of the printable dry granules are continuous rather than discrete, the printing fineness of the dry granules is greatly improved, the printed pattern lines can be continuous, the resolution ratio is high, and the thickness of the lines can be controlled below 5 mm. And because the dry particles are not easy to agglomerate and dry and are not sticky, the dry particles are not accumulated in the bent blanking hose 11 and can be completely output along with the air flow.
Preferably, each of the air inlet branch pipes 32 is further provided with a pressure regulating valve 34, and an air inlet of the pressure regulating valve 34 is communicated with an air outlet of the on-off control valve 33;

Because the bending degrees of the blanking hoses 11 of each blanking box 1 are not completely the same, the consistency of blanking time can be affected, and further the blanking position of dry granules deviates, and when the air pressure is higher, the flow rate of the compressed air is higher, and the blanking speed of the dry granules stored in the blanking cavity 13 of the blanking box 1 under the action of the air flow of the air inlet branch pipe 32 is higher, the air pressure of the corresponding air inlet branch pipe 32 can be adjusted through the pressure adjusting valve 34, so that all blanking boxes 1 can synchronously blank, and the accuracy of dry granule positioning printing is improved.
The conveying speed (namely the green brick moving speed) of the conveying belt 4 and the air flow speed (namely the blanking speed) of the compressed air are matched with each other, so that dry granules can be continuously printed on green bricks along the conveying direction of the conveying belt 4, and the phenomena of vacancy and the like are avoided.
When the pressure and the flow rate of the compressed air delivered by the air source device 2 are higher, the flow rate of the compressed air is higher, the blanking speed of the dry granules stored in the blanking cavity 13 of the blanking box 1 under the action of the airflow of the air inlet branch pipe 32 is higher, the efficiency and the accuracy of the dry granule positioning blanking are effectively improved, and when the pressure and the flow rate of the compressed air delivered by the air source device 2 exceed a limited range, the dry granules are easy to splash after being sprayed out of the blanking pipe 11 under the action of larger airflow, so that the pattern effect of the dry granule positioning blanking is influenced;

Since there may be very few dry pellets that may fall obliquely downward during pressure relief, rather than vertically, the opening of the oblique cut 111 is preferably oriented in the conveying direction of the conveyor belt 4 to avoid that the obliquely falling dry pellets spill over areas where no dry pellet printing is started, and to reduce the effect of these obliquely falling dry pellets on the printed image.
The maximum particle size of the dry particles is about 1mm, the diameter of the discharging pipe 11 is 2-4 mm, and therefore when the dry particles enter the discharging hose 11 in the discharging cavity 13, due to friction among the dry particles, discharging is difficult simply by gravity, and the dry particles cannot be discharged to the discharging hose 11 from the discharging cavity 13 when air is not sprayed; moreover, all the blanking cavities 13 of the blanking box 1 are converged to the same blanking hose 11 for blanking, and one of the blanking cavities 13 is pushed by compressed air to carry out blanking, so that the pressure of the compressed air can be applied to operate on different air inlet branch pipes 32 to achieve the purpose of virtual switching, namely one of the blanking cavities 13 of the blanking box 1 is kept for blanking forever, and meanwhile, the air flow entering the blanking hose 11 downwards generates an acting force for blocking dry particles from sliding downwards on the other blanking cavities 13, so that the dry particle distribution is finally ensured not to exist at the position where the dry particles are not required to be distributed.
