For convenience of description, the direction of product movement is oriented back, i.e., in the direction of the arrow in fig. 1, and front and back are reversed.

Referring to fig. 1-4, the utility model provides a silk screen and inkjet combined ceramic printing system, which comprises a first conveyor belt 1 and a second conveyor belt 2 which are parallel to each other, a corner conveyor belt 3 connected to one end of the first conveyor belt and the second conveyor belt, a distributing device 4, a press 5, a drying kiln 6 and a glaze spraying machine 7 which are arranged above the first conveyor belt 1 in sequence from front to back, a printing machine combination 8 and a firing kiln 9 which are arranged above the second conveyor belt 2 in sequence from front to back; the printer assembly 8 comprises at least one inkjet printer 8.1 and at least one screen printer.

During operation, the material is distributed by the distributing device 4, then the powder is pressed into a green body by the press 5, the green body is dried in the drying kiln 6 to form a dry body, a glazing layer is distributed on the upper surface of the dry body by the glazing machine 7, then the pattern printing is carried out by the printing machine combination 8, and finally the green body is fired and formed in the firing kiln 9. Because the printer combination 8 comprises at least one ink-jet printer 8.1 and at least one screen printer, a plurality of layers of concave-convex patterns (such as local convex regions, convex lines, convex points and the like, the patterns can be colored ink or transparent glaze) can be printed by the screen printer, and a plurality of layers of fine patterns can be printed by the ink-jet printer, so that fine and stereoscopic patterns can be obtained by multiple times of printing; according to the ceramic printing system, the first conveying belt 1, the second conveying belt 2 and the corner conveying belt 3 form a conveying system, and all devices are arranged in two rows, so that the span of the system can be greatly reduced, and the requirement on a field is reduced.

It should be noted that the number of the inkjet printers 8.1 and the screen printers in the printer assembly 8 can be set as desired, and the arrangement order between them is not limited, and can be set as desired.

In some embodiments, a glaze shower 10 is provided between the press assembly 8 and the firing kiln 9. The glazing machine 10 can apply a layer of protective glaze on the surface of the pattern to form protection for the pattern.

In this embodiment, two glaze showering machines 7 are arranged on the first conveyor belt 1 behind the drying kiln 6, so that the ground glaze and the cover glaze can be applied according to the requirement.

Further, as shown in fig. 1 and 2, two positioning plates 11 are symmetrically arranged on two sides of the second conveyor belt 2, and the distance between the two positioning plates 11 is the same as the width of the dry blank (i.e. the dry blank of the ceramic tile); the front ends of the two positioning plates are bent outwards to form a gradually narrowed splayed guide area A (shown in figure 2) between the two positioning plates. After the dry blank passes through the corner conveyor belt 3, the position and the orientation of the dry blank can be deviated, so that the deviation of the pattern printing position can be caused to form waste products; here, before entering the printing press assembly 8, the dried blanks are guided by the front ends of the two positioning plates 11 to eliminate the position and angle offset, and the correct position and orientation are always kept in the printing process, so that the printing position deviation is avoided to form waste products.

Further, the height of the positioning plate 11 is smaller than the thickness of the dry blank, so as to avoid the positioning plate 11 from obstructing the operation of the printing machine (especially the screen printing machine).

In a preferred embodiment, referring to fig. 2, a plurality of sliding rods 11.1 extending along the width direction of the second conveyor belt 2 are disposed outside the positioning plate 11, each sliding rod is slidably inserted into one L-shaped connecting seat 11.2 and locked by a locking screw 11.3, and the lower end of the L-shaped connecting seat 11.2 is fixedly connected with the frame of the second conveyor belt 2. The distance between the two positioning plates 11 can be adjusted according to the actual size of the dry blank, and the applicability is improved.

For the convenience of operation, L type connecting seat 11.2 sets up the position between each equipment, need the handle to stretch into the equipment below when avoiding adjusting.

Further, the rear end of the positioning plate 11 extends to the front side of the inlet of the firing kiln 9. Because the positioning requirement on the green body in the firing kiln 9 is not high, and the length of the firing kiln 9 is large, the positioning plate 11 does not extend into the firing kiln 9, so that the length of the positioning plate 11 can be greatly reduced, and the positioning plate can be more conveniently and quickly adjusted.

In some embodiments, see fig. 3, the inkjet printer 8.1 has a plurality of inkjet print heads 8.1a, each inkjet print head 8.1a is connected to a suction ring 8.1b, and all suction rings are connected to a suction fan 8.1c via a pipe. Waste ink and vapor that ink jet printer produced in the printing process can adsorb on ink jet printer head often, can drop down and pollute the ceramic brick and form the waste product after accumulating certain degree, can suck waste ink and vapor through air suction ring 8.1b and suction fan 8.1c and avoid the emergence of this phenomenon.

Here, the suction rings 8.1b may be connected to the suction fan 8.1c through a pipe, respectively, or as shown in fig. 3, a main pipe 90 connected to the suction fan 8.1c may be provided, and the suction rings 8.1b are connected to the main pipe 90 through a branch pipe 91, respectively.

Specifically, referring to fig. 4, the air suction ring 8.1b includes a connecting portion 8.1b1 for connecting with the upper portion of the ink jet print head 8.1a, and an annular air suction groove 8.1b2 surrounding the lower portion of the ink jet print head 8.1 a; a gap 8.1b3 is formed between the inner side wall of the annular air suction groove 8.1b2 and the ink-jet printing head 8.1a, an annular air suction hole 8.1b4 is formed in the inner side wall along the circumferential direction, and a connecting nozzle 8.1b5 is arranged on the outer side wall of the annular air suction groove.

The connecting nozzle 8.1b5 is used to connect with the pipeline, when the suction fan 8.1c is working, the waste ink and the water vapor will be sucked into the annular suction groove 8.1b2 from the annular suction hole 8.1b4, and finally sucked out from the pipeline, because the annular suction hole 8.1b4 is arranged around the whole circumference of the ink-jet printing head 8.1a, there is no dead space, and the waste ink and the water vapor can be reliably sucked away.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-mentioned preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and the embodiments are substantially the same as the present invention.
