A kind of production method of ceramic tile blank and device
Technical field:
The present invention relates to a kind of production method of ceramic tile and produce dress.
Background technology:
The method that existing production has the ceramic tile blank of pattern is with the random distributing form multiple powder to be arranged in the material containing grid, move by grid, make powder barrel shift and produce pattern effect in grid, through press compression moulding is the ceramic tile blank that has pattern, the ceramic tile blank that adopts this kind mode to produce, the thick Kuang of pattern, meticulous inadequately, and, the pattern poor repeatability.
Summary of the invention:
Goal of the invention of the present invention is to provide that a kind of pattern is meticulous, the production method of the ceramic tile blank of good reproducibility and device.
The production method of ceramic tile blank of the present invention is to realize like this, earlier make corresponding color lump half tone according to the color lump on the ceramic tile layout, successively every color lump half tone is positioned on the grid then, corresponding ceramic toner is laid on the grid position corresponding with the pattern color lump by the mesh on the color lump half tone, after treating that all ceramic toners all drop into grid and form complete pattern, ceramic powder is pushed on the press die by grid, with press ceramic powder is pressed into ceramic tile blank.
Here, can be in grid when preventing ceramic powder with the grid translation barrel shift, tentatively suppress with the ceramic powder in the precompressed mechanism plaid matching grid, make its shape basic fixed, with grid it is pushed on the press die again.
The process units of ceramic tile blank of the present invention is to realize like this, comprise press, material-feeding mechanism, its special feature be material-feeding mechanism mainly by the frame that has platform, be arranged on grid on the framework platform, be positioned at the cover web plate that has thrust unit above the grid, the ceramic toner blanking mechanism corresponding with every block of web plate in the cover web plate constitutes.During work, every block of web plate in the one cover web plate is under the drive of thrust unit, be positioned at successively on the position of the correspondence above the grid, ceramic then toner blanking mechanism drops into corresponding ceramic toner on the corresponding position of grid by the web plate mesh, after treating to have filled up ceramic powder on the grid, by grid with ceramic powder be advanced to press die above, decline along with core rod in the mould, ceramic powder in the grid drops in the mold mould frame, after treating that the interior ceramic powder of grid all drops in the mold mould frame, grid is removed, and the press pressurization is pressed into ceramic tile blank with ceramic powder.
Here, a precompressed mechanism is set on frame.During work, treat that grid falls behind the full material, carries out precompressed with the ceramic powder in the precompressed mechanism plaid matching grid earlier, make ceramic powder obtain preliminary fixing, like this, ceramic powder is shifted onto in the process of mold mould frame by grid, the ceramic powder in the grid just can not barrel shift.
The present invention compared with the prior art, the ceramic tile blank that manufacturing is come out has that pattern is meticulous, the advantage of good reproducibility.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a vertical view of the present invention.
The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:
As shown in the figure, the production method of ceramic tile blank of the present invention is to realize like this, earlier make corresponding color lump half tone 7 according to the color lump on the ceramic tile layout, successively every color lump half tone 7 is positioned on the grid 5 together with the ceramic toner blanking mechanism corresponding with it then, corresponding ceramic toner is laid on the grid position corresponding with the pattern color lump by the mesh on the color lump half tone 7, after treating that all ceramic toners all drop into grid and form complete pattern, tentatively suppress with the ceramic powder in the precompressed mechanism plaid matching grid, make its shape basic fixed, ceramic powder is pushed on the press die by grid, with press ceramic powder is pressed into ceramic tile blank.
The process units of ceramic tile blank of the present invention is to realize like this, comprise press 1, material-feeding mechanism 2, its special feature be material-feeding mechanism 2 mainly by the frame 4 that has platform 3, be arranged on grid 5 and precompressed mechanism 6 on frame 4 platforms 3, be positioned at the cover web plate 7 that has thrust units above the grid 5, the ceramic toner blanking mechanism 8 corresponding with every block of web plate in the cover web plate 7 constitutes.Pottery toner blanking mechanism 8 is made of blanking hopper 8a, the scraper plate 8b that is positioned at the blanking frame.During work, blanking hopper 8a adds to powder in the place that does not have mesh in the web plate 7, and then shift ceramic powder onto web plate 7 meshed places by scraper plate 8b, ceramic powder is seen through mesh to be filled on the corresponding position of grid, withdraw from current web plate afterwards, another piece web plate is entered above the grid 5, fill another kind of ceramic toner.
