Description

A kind of Ceramic Tiles forming method and equipment

One, technical field

The present invention relates to a kind of forming method and equipment of Ceramic Tiles, particularly relate to a kind of method and apparatus that can finish multiple cloth decoration operation and be fit to the different-thickness product shaping.

Two, background technology:

The Ceramic Tiles moulding has two kinds of methods now.(1) a kind of method is a grid feeding pressing.This method comprises grid, upper punch, low punch and fixing framed.Be fixed with many orthogonal glazing bars in its grid.Its workflow is: ceramic powder arrives hopper by feed bin through the material pipe, when the grid level is shifted to press, bunker gate is opened, grid is filled powder, and moves to the low punch top, and low punch moves down, powder fills up die cavity, grid returns, and wherein unnecessary powder is taken back, and simultaneously die cavity powder surface is wipeed off.Upper punch descends, and the powder in the die cavity is compacted into base substrate, rises in the back, and low punch rising subsequently ejects base substrate.Grid moves to the press direction along level once more, and base substrate is released press, and low punch descends, and is reinforced to die cavity, realizes a working cycles.

The advantage of this kind forming method is adopt rigidity fixing framed, controls the powder loadings by the falling head of regulating low punch, promptly controls the thickness of product.Thick partially Ceramic Tiles plate (6-25mm) during this is suitable for being shaped, during moulding splits (3-6mm), adobe is released and easily is damaged.

The shortcoming of this kind forming method is to adopt grid powder to be transferred to the feeding form of die cavity, though the existence of glazing bar is beneficial to even feeding in the grid, but powder has the figure line that arranges in advance in grid, during slice, powder is in the die cavity process of whereabouts, grain pattern can be subjected to the cutting damage of glazing bar, the formation of unfavorable decorative effect.(2) another kind of method is a belt feeding pressing, the international ceramic machinery exhibition that 1-5 day in October, 2002 holds at Italian Balogana (POLO take), and Italian System company puts on display this novel device.

This method comprises cyclical level belt, upper punch, low punch.Its workflow is: cyclical level belt support live ceramic powder and move to upper punch and low punch between, stop, upper and lower drift is exerted pressure to powder, elasticity surrounding edge and belt, powder is pressed into base substrate.Belt movement shifts out press with base substrate, powder is moved between upper and lower drift exert pressure simultaneously, finishes a working cycles.Wherein the elasticity surrounding edge is affixed on upper punch, and during pressurization, with the powder pressurized, powder leaks when avoiding press to exert pressure.

The advantage of this kind forming method is: the level band is passed between the upper and lower drift of press along reaching the outer other end of press by the outer end of press, returns the original place, constitutes a cycle operation system.Powder on the level band, disembark (press) carry out window dressing operations such as multiple cloth, xerography.Simple to operate, safety, and decoration process is after finishing, and powder keeps relative static with the level band, no relative motion, before the punching press, the figure line remains unchanged.Base substrate after the moulding shifts out press by level band support, the base substrate shaping of cutting edge.Thereby be suitable for the moulding (thickness is 3-5mm) of ceramic thin plate.

The shortcoming of this kind forming method: be not suitable for the ceramic product of molding thickness greater than 8mm, main cause is because its elasticity surrounding edge is an elastomer, it is affixed on the drift, in the forming process, when thickness increased, lateral thrust increased, make the frictional force between elasticity surrounding edge and drift be not enough to resist the lateral thrust of powder, generation is out of shape or is come off, and the shape of base substrate can not be kept, and half-finished uniformity and quality will can not get guaranteeing.

Three, summary of the invention

Technical problem underlying solved by the invention: (1) can mold the ceramic product of different-thickness (3-25mm); (2) the conveniently operation of multiple cloth, decoration; (3) stability of assurance pattern, striped.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is made up of a set of equipment and the method for using this equipment.

Former of the present invention system includes a cyclical level feeding belt, is mounted with one group of hopper and several cloth, decoration device above its front end.Moulding press is installed in the middle, and press includes upper punch, low punch, and alignment pin and the slip that cooperates with upper punch are framed, and the level band passes between upper and lower drift.

In addition, the forming method of application the said equipment of the present invention system, its concrete steps comprise: (1) hopper and cloth, decoration device are to level band feeding; (2) the level band is delivered to powder between upper and lower drift; (3) framed being displaced downwardly to belt of slip contacts; (4) upper punch moves down (or moving on the low punch) to the powder moulding of exerting pressure; (5) slide and to move on framed; (6) move (or low punch moves down) on the upper punch; (7) base substrate shifts out press, and powder moves into press simultaneously.

Against existing technologies, the present invention has following several useful effects:

(1) the present invention helps finishing of multiple decorative means and stablizing of decorative effect in forming process.Adopted the feeding form of the spring level band of circular gap motion, for safety outside press, finish decorations such as various location cloth, random distributing, xerography, impression easily operability be provided, have lines, the powder of figure line keeps relative static with the level band, is not changed before punching press.

(2) former of the present invention is suitable for the moulding of all thickness (3-25mm) ceramic product generally.Adopted recirculated water flat rubber belting support base substrate to shift out the ejection form of press, for the splits less than 6mm, base substrate shifts out press and can not damage.Adopted the rigidity that can vertically slide that matches with upper punch framed, at first, the framed thick brick plate of moulding (6-25mm) that guaranteed of rigidity, powder is to the requirement of strength of framed lateral thrust.Drift and framed accurate contraposition have been guaranteed simultaneously.When framed level band and the powder thereof of when upper, being beneficial to, the moving of base substrate.

(3) former operation of the present invention is simple.The framed cross section of rigidity is designed to perpendicular on one side, and another side is the wedge face.When framed moving down, powder is separated, be the required powder of base substrate in the perpendicular, the residue powder is released by the wedge face.Base substrate shape after the moulding is regular, need not cutting.Reduced the base substrate cutting action of existing belt feeding punching press.

(4) former highly versatile of the present invention, method is simple and practical, and is less demanding to the manufacturing of equipment, and easy to operate, productive rate is higher, steady quality, decorative effect are remarkable.
