Description
Technical field
The utility model relates to a kind of former of ceramic, particularly relates to a kind of former of large size ceramic thin plate.
Background technology
In ceramics, the large size ceramic thin plate typically refers to thickness and is less than or equal to 5 millimeters and area more than or equal to 0.5 square metre ceramic board.And the ceramic thin plate compression molding device is mainly used half-dried powder filling press compression moulding in framed at present, release the semi-finished product of moulding framed then or with vacuum sucking-off frame, but it is fragile mashed when big specification thin plate semi-finished product are released framed or vacuum sucking-off, yield rate is lower, and the tonnage of the required press of moulding is bigger, causes that the former manufacture difficulty is big, input cost is high.And Italian SYSTEM company discloses a kind of large size ceramic sheet forming equipment of two-way compacting first in the Italian international ceramic exhibition of holding in Italian Montreal city in October, 2002.This equipment can be produced the large size ceramic thin plate of 1000 * 3000 * 3mm, it has two drifts up and down, the half-dried powder of pottery is sent between the press plane punch by conveyer belt, then by the pressurization that liquidates of last low punch, disposable ceramic powder is pressed into the thin plate semi-finished product.After drift unclamps, hold semi-finished product by conveyer belt and shift out press.Because of the force way of ceramic powder in press is the vertical pressurized in plane, lifting surface area is big, and the required pressure of compression moulding is also bigger, thus this press tonnage up to 15000 tons, its manufacture difficulty is big, and the manufacturing cost height.
Summary of the invention
The purpose of this utility model is the technical problem big at existing large size ceramic sheet forming equipment tonnage, that making is difficult, cost is high, a kind of new large size ceramic sheet forming equipment is provided, and it can improve the half-finished Forming Quality of large size ceramic thin plate and reduce manufacturing cost.
To achieve these goals, the large size ceramic sheet forming equipment that the utility model provides has a frame, supporting plate, the delivery wheel of belt and hopper under the transmission, wherein above frame, be provided with upper pressure wheel and be arranged on outside the upper pressure wheel circumferential surface on belt, following methods, rack place at upper pressure wheel is provided with the base that a upper pressure wheel can back and forth roll thereon, powder is transported between upper pressure wheel and the base by following belt, by upper pressure wheel on base reciprocal rolling and with powder compression moulding.Like this, with respect to the big former of tonnage, the utility model can be implemented in reduce production costs and the basis of equipment cost on improve the Forming Quality of large size ceramic thin plate greatly.
On the other hand, the described base of first aspect can also be changed into and the bearing of the corresponding lower pressure wheel of upper pressure wheel, by the rolling of upper pressure wheel and lower pressure wheel, powder therebetween can be suppressed, and improve shaping speed and quality with the supporting lower pressure wheel.
Can also also establish a prepressing device between described hopper and upper pressure wheel in addition, this prepressing device can carry out precompressed to powder before roll extrusion, can further increase the Forming Quality of large size ceramic thin plate.
This prepressing device can be existing common press-molding device, also can prepressing device be set to form by two parts up and down, top is divided into a metal cap, the metal cap bottom is provided with a gland, the frame of gland lower edge metal cap is provided with seal, have the pore that several are connected with exhaust tube on the gland, exhaust tube stretches out outside the metal cap and is connected with first reversal valve, first reversal valve also connects pumped vacuum systems and air inlet pipe respectively, form a sealed cavity between metal cap and the gland, on metal cap, also be provided with the gas tube that is communicated with sealed cavity, gas tube stretches out outside the metal cap and is connected with second reversal valve, and second reversal valve also connects compressed air system and blast pipe respectively; The bottom of prepressing device is divided into lower seal body base corresponding with the metal cap frame on the supporting plate.
By following belt, on the tiny channel of a plurality of perforations is set on belt, upper pressure wheel and the base, the gas in the powder further can be discharged, all very favourable to shaping speed and quality.
Because the utility model has adopted the mode of movement of conveyer belt support powder and base substrate, so the thickness of ceramic thin plate can reduce greatly, therefore can save raw material in a large number, reduces production costs.Simultaneously, because the employing of the utility model former is method for rolling and molding, powder is being suppressed between pinch roller and the pinch roller or between pinch roller and the base, and pinch roller is that line contacts with the powder plane in theory, and promptly the compression area of powder is little.Compare with existing impact forming method, it is less that the powder of pinch roller roll forming will reach the identical needed pressure of pressure.It is calculated that the production width is 1 meter a ceramic thin plate product, the tonnage of pinch roller roll extrusion press only needs 250 tons and gets final product.And the large-scale former that Italian SYSTEM company released in October, 2002 is that to produce width be 1 meter ceramic thin plate product equally, and its punching press press tonnage is unexpectedly up to 15000 tons.By contrast, its manufacture difficulty of former provided by the utility model and cost of manufacture all reduce greatly.Therefore, the utility model compared with prior art can obviously improve Forming Quality and improve output and reducing cost.
