The specific embodiment:
Below in conjunction with a preferred embodiment method and apparatus of the present invention is further specified,
See shown in accompanying drawing 1~accompanying drawing 5:
This preferred embodiment is adopted three layers and is pushed away powder frame (seeing shown in Figure 4), base material small bucket 8 is installed in first and pushes away on the powder frame A, transition material small bucket 12, line material small bucket 15 and 16, masterplate 18 are installed in second by illustrated order and push away on the powder frame B, bundle ditch mechanism 19 is installed in the 3rd and pushes away on the powder frame C, but three layers push away the relative motion of powder frame.With three kinds of particulate material: pale yellow 20%, common white material 60%, pale red material 20% mixes in the big bucket 7 of back dress base-material, and base-material falls into basic material small bucket 8 through the big bucket 7 of base-material.The transition material is by translucent white material 40%, super-white marerial 20%, and pale red material 20% is mixed into the semi-homogeneous state big bucket 11 of transition material of packing into through special blender 10 and falls into transition material small bucket 12 again after disintegrating machine is broken into micro mist respectively.With pale red material and translucent white material respectively in accordance with regulations technology be broken into the lines material big bucket 13 of line material and 14 of packing into and fall into line material small bucket 15,16 again, line material small bucket feed opening is wide to be 20mm, and is covered with one 60 purpose stainless steel mesh.Masterplate 18 is to adopt the column (seeing shown in the accompanying drawing 5) that cuts into filler by layout, and thickness is 8mm, and glacing flatness is≤0.1mm, and the surface is very smooth.Velocity of rotation by four rollers is rotated in the ratio of design, thereby the proportioning that obtains powder is pale yellow material 25%, translucent white material 40%, super-white marerial 20%, pale red material 15%, wherein the translucent white material is pressed into loose bulk (if adopting roller 22,26 precompressed then can obtain the stratiform or the block effect of multiple color) in advance through a plurality of precompressed rollers 21, sends into the big bucket 17 of master pattern material behind conveyer belt 25 and blank device 20.The big bucket 17 of master pattern material can move forward and backward and oscilaltion.When the big bucket 17 of master pattern material during to masterplate 18 clothes, prick ditch mechanism 19 and move backward to the position of not colliding hopper, the big bucket 17 of master pattern drops to default position, open the sluices to masterplate 18 clothes and mobile backward, cloth big bucket 17 closed shutters of intact back master pattern material and rising reset, prick ditch mechanism 19 and move forward to the position that aligns with masterplate this moment, finished the charging work of all material this moment.
See shown in accompanying drawing 1~accompanying drawing 2, when the press compacting finishes, provide and allow the cloth signal, first pushes away powder frame A moves forward to the mould that masterplate 18 aligns press, and masterplate 18 is directly over lower mold core 3 at this moment, and lower mold core 3 descends the first time (seeing Fig. 1 cloth process 1), the decline degree of depth is 10mm, powder in the masterplate falls into die cavity 4, and the cross section is slick and sly stacking yard shape, is local windrow state on the lower mold core face.When lower mold core 3 descends, prick ditch mechanism 19 usefulness cylinders and will prick ditch mould bar (see figure 3) and stretch in the die cavity powder is bundled into V-arrangement ditch (seeing Fig. 1 cloth process 2), pricked exhaust hood and withdrawn.Pushing away in succession masterplate 18, line material small bucket 15 and 16, transition material small bucket 12 of powder frame B this moment second moves backward, when line material small bucket 15 and 16 moves to cavity side, begin vibration, purpose is to stop vibration after the line material (seeing Fig. 1 cloth process 3) of the about 1~2mm of sieve one deck in die cavity has sieved, and screen cloth no longer leaks powder when stopping to vibrate.When transition material small bucket 12 moves to cavity side, open the sluices and vibrate filler in die cavity with cylinder, complete the back and wipe (seeing Fig. 1 cloth process 4) off.Have the line feed collet of 1~2mm this moment between master pattern material and transition material.Mould descends for the second time and recharges base-material (seeing Fig. 1 cloth process 5) then, the about 22mm of the decline degree of depth, pushing away the powder frame basic material small bucket 8 of ining succession then moves backward in the die cavity filler and wipes off, completing material pusher powder frame resets, press compacting (seeing Fig. 1 cloth process 6) after lower mold core descends for 3 three times, overall process circulates with this.The green compact of compacting are polishing again after burning till, and the thickness of polishing is 1.3mm, and this moment, default superficial makings effect all presented.
Wherein, master pattern material and transition material adopt the process of powder process, batching and the broken micro mist of conventional super micro-powder brick, and moisture content is that 6% ± 0.2%, 80 mesh sieve clouts are 10%~15% fineness.The moisture content of line material is 3% ± 0.2%, and fineness is 100 mesh screen residues 8% ± 1%.
Designed pre-compression functions in the roller ingredient sector of pattern material, the micro mist of multiple different colours such as a kind, 2 kinds or 4 kinds is through conveyer belt 25 time, be pressed into bulk by precompressed roller 21,22,26, adjust precompressed roller and the height of belt and the gap of roller and roller, can adjust the block intensity of compacting, be cut into the bulk of default size then through blank device 20, it is stand-by to fall into the big bucket of master pattern material 17 through swash plate.The method is to allow the brick face of institute's cloth that layered effect is arranged, and particularly utilizes the technology of translucent material, makes translucent material have very strong natural stone sense effect at ceramic brick surface.
In addition, transition material and master pattern material can adopt micro mist, also can adopt the made powder of common spray tower, obtain multiple different pattern decorative effect by changing powdery row material characteristic or color.
The embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so the equivalence that all methods according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
