Description

[0001] APPARATUS FOR SIMULTANEOUS MOLDING OF TILES [0002]

The present invention relates to a tile molding apparatus, and more particularly, to a tile molding apparatus capable of continuously molding a plurality of tiles at the same time with a single molding die, The present invention relates to a tile continuous molding apparatus capable of forming a continuous continuous pattern.

Various types of tiles are used as interior materials for finishing walls or floors during construction or interior construction. Typical materials for making such tiles include kaolin and clay. In general, a mixture obtained through a coma and a kneading process is continuously extruded through a mold, cut into a predetermined size, dried and fired to produce tiles.

At this time, the existing molding frame used for extrusion molding of the tile straps has a problem in that the productivity of the tile is remarkably decreased because the tile strap can be extruded only by one line.

There have been attempts to increase the height of the mold and to produce a plurality of tiles at the same time by dividing the tile strap discharged through the wire represented by the core or piano wire. However, in the conventional core-type method, In addition, the workability due to the unevenness between the two molded parts was lowered. In order to separate the two tile straps, a sheath was provided on both sides, and the impact was applied to the sheath after firing, It has a disadvantage that it is impossible to treat color or glaze.

In addition, although a plurality of wires can be simultaneously extruded by providing a plurality of wires, there is a problem that the wires are stretched or broken due to the force applied to the wires, and it is not easy to find even if the wires are broken during extrusion. When the tile strap was removed from the cabinet, it was not possible to treat and color or glaze the pattern at a high breakage rate and separation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

Fig. 1 is a structural view of a tile continuous molding apparatus according to a first embodiment of the present invention. Fig. 2 is an operation diagram of Fig. 1, in which a plurality of tile materials extruded through a molding die 20 are separated, The tile continuous molding apparatus 100 is capable of simultaneously molding the tiles.

 The continuous tile forming apparatus 100 is an apparatus for forming a continuous tile strap by extrusion molding a tile material before proceeding with a cutting process and a firing process and includes an extruder 10, 20 and a main part of the separating means 30. [

The extruder 10 functions to extrude the kneaded tile material into the molding die 20 at a constant speed while kneading various materials for making the tile including the clay material together with water at a predetermined ratio. A variety of known materials may be used depending on the use and the form of the tile, so that a detailed description of the material will be omitted.

The forming die 20 is connected to the front end of the extruder 10 so that the tile material extruded through the extrusion holes 21 having a size equal to or more than the sum of the tile thicknesses to be produced is made into a continuous tile shape and discharged .

The separating means 30 separates the material to be extruded into the tile thicknesses of each tile 51 so that the extrusion hole 21 can be divided into tile sizes 51, .

In the first embodiment of the present invention, the separating means 30 is formed in the transverse direction and the tile material to be extruded is divided into two pieces, and the tile material which is finally extruded is divided into three pieces of upper, middle and lower portions . At this time, the number and spacing of the separating means are appropriately set according to the number of tiles to be produced at the same time and the thickness of the tile, and correspondingly an extrusion hole 21 having an appropriate size should be provided. Preferably, It is possible to make the division in the range.

The width of the extrusion hole 21 may be equal to the width of the tile to be produced and the height of the extrusion hole 21 may be substantially equal to the total thickness of the tiles 51 to be simultaneously produced. The tile material is separated vertically through the separating means 30 so as to prevent the tile material from being attached again with the discharge in a separated state, ) Is preferably formed.

As described above, in the related art, the wire harness or the like has been used as the separating means 30, but there has been a problem of high durability. Therefore, the improved structure of the core strip 31 is applied in the present invention.

3 is a perspective view showing a state of the core band according to the first embodiment of the present invention.

The core base 31 is installed in the form of a conventional wire-like wire crossing the extrusion hole 21 and is divided into a material to be extruded and a resistance to continuous contact with the divided tile material is minimized So as to have a circular cross-section or a elliptical cross-section.

Particularly, in the present invention, a notch 32 having a blade function is formed on the core bed 31 so as to facilitate the division of the tile material to be extruded, in the direction of the extruder 10. At this time, the cross section of the cut-away body 32 has a thick central portion, that is, a thin elliptical or rhombic shape with respect to the front end and the rear end. As a result, the separation surface is not crushed by the sharp tip, the smooth surface is maintained, and the division is made easily. As a result, a gap is generated between the materials divided by the thickness of the center portion, have.

Since the tile 51 separated and discharged through the separating means 30 has a long shape as a strap, it is manufactured as a finished tile 51 product through a predetermined cutting process and a firing process, A plurality of tiles 51 can be simultaneously formed through the apparatus 100 for continuously forming a tile according to the first embodiment, so that the production efficiency is very high, and a structure capable of producing a good quality tile while lowering the manufacturing cost of the tile .

In this case, the outer shape is very similar to the core band 31 in the first embodiment, but the core band 31 in the second embodiment is formed in a hollow tube shape, A plurality of pigment discharge holes 313 are formed along the longitudinal direction so that the pigment can be discharged in a direction in which the material in the opposite direction of which the core 32 is formed is discharged. A pigment 311 is formed so that the pigment supplied by the external pumping means can be discharged through the pigment discharge hole 313. [

In this case, the pigment to be supplied may be various liquid or powder type pigments for imparting color to the tile. Basically, as the pigment becomes non-tacky, the tile materials to be divided and extruded can be prevented from sticking to each other do. In addition, when the pigment is applied to the pigment, it is also possible to insert successive colors of two colors by injecting different pigments through the pigment input portion 311 formed at both ends of the core table 31.

In addition, the supplied pigment may be glazed to impart gloss to the surface of the tile and to add strength to the surface of the tile and to prevent the surface from becoming dirty. This can eliminate the absorptivity on the surface of the tile produced and increase the resistance to water or chemicals. As the thermal expansion coefficient of the used glaze is almost the same as that of the tile material, when the glaze is heated, it melts well and flows closely to the tile to produce a thin glass film on the surface.

FIG. 5 is a view illustrating an installation of a core band according to a second embodiment of the present invention.

Although various methods can be applied to provide the core frame 31 to the mold frame 20, the core frame 31 may be fixed to the front surface of the mold frame 20 as in the second embodiment of the present invention. And a fixing part 23 configured to cover the front surface of the insertion part 22 after inserting the core rod 31 into the insertion part 22 is formed in the insertion part 22, (31) is fixed at the front by bolting.

In this case, the pigment injecting unit 311 includes regulating means 312 such as a regulating valve for individually controlling the pressure of the pigment to be supplied when the pigment is supplied through the pumping means and the supply tube, 313) to control the amount of pigment discharged, so that the color or pattern can be changed through the pigment.
