detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

FIG. 1 shows an example of the distribution equipment of the present invention. The lower pipe 7 lowers various powders into the feeder 1, and the feeder 1 moves back and forth in the left and right direction of the press 5 on the distribution bucket 2. Feed the cloth bucket 2; the cloth bucket 2 or the grid 3 moves in the forward and backward direction of the press 5, the cloth bucket 2 feeds the grid 3; the grid 3 on the bottom plate 4 moves to the press 5 to the mold frame 6 Cloth. The feeder 1 is the feeder shown in FIG. 8 and FIG. 9, and the cloth hopper 2 is the cloth hopper shown in FIG. 4.

Figure 2 shows the existing cloth bucket. As shown in Figure 3, when the existing cloth bucket is in the cloth, because the powder has good fluidity, when the cloth bucket supplies the grid cloth, the powder in the bucket will The flow is generated, and unintelligible mixing occurs automatically during the flow. Therefore, even if the various powders are arranged in the cloth bucket one by one according to the design requirements, the powder that is clothed into the grid by the cloth bucket, Its pattern is still difficult to control. When the interior of the original cloth bucket is spaced into two or more cloth spaces in the direction of the grid movement, the mixing of the powder in the cloth bucket can be significantly reduced, as shown in FIG. 6.

As shown in FIG. 3, assuming that the height of the grid is h cm, the relative moving speed of the cloth bucket and the grid is a cm / second, and the powder flow rate is c cm / second, and the cloth bucket and the grid are perpendicular to the grid. The width in the moving direction of the grid is the same. The cloth bucket and the grid are moved once relative to make the grid full of powder. The width of the feeding opening of the cloth bucket in the moving direction is b cm.

_Ί ah

c

From the above formula, b is proportional to the height of the grid and the relative moving speed of the bucket and the grid, and

5

Replacement page (Article 26) Powder flow speed is inversely proportional.

In actual production, generally a is about 10-25 cm / s and c is about 37-47 cm / s. Therefore, b is about (0.2-0.7) h.

When a is 18 cm / s, h is 3 cm, and c is 45 cm / s, then b is 1.2 cm. Figure 4 shows the cloth buckets that are open up and down and are vertically connected by four vertical walls. The inside of the cloth bucket is fixedly spaced into 4 cloth spaces by vertical plates in the direction of the grid movement. The width in the moving direction is 1.2 cm; as shown in Figure 5, when the cloth bucket is given to the grid, it is a cloth space and a cloth space is given to the grid. The powder in the cloth space is first put into the grid, and the powder in the cloth space is put into the grid layer by layer from bottom to top. In this way, the space is divided into layers in the cloth bucket according to the design requirements in advance. The distribution pattern of various powders laid out in the area will be regularly maintained in the grid by the cloth bucket. When there are thin layers of powder with different thickness in the cloth bucket, there will also be corresponding thin layers of powder in the grid. The grid with different patterns is pushed into the press mold frame to be pressed. After firing and polishing, the polished surface is Corresponding slender stripe patterns with different thicknesses and different lengths will be presented. As shown in FIG. 10, this pattern is common throughout the body, as shown in FIG. 11. Therefore, by designing the distribution of various powders in each cloth space in the cloth bucket, and realizing this distribution through the feeder, combined with the pattern in the grid, ceramic tiles with corresponding patterns can be produced. Here, when distributing cloth, the cloth bucket not only plays a role of filling the grid, but also plays a role in keeping the distribution of various powders in the bucket regularly in the grid. There is no doubt that in the direction of the grid movement, the internal width is 1.2 cm, and there is only one cloth hopper inside the cloth hopper, which has a large enough capacity (such as a high enough height). It can also regularly layer the powder, Arranged from bottom to top in the grid, the above effect is produced. It is not difficult to understand that when the width of the cloth space in the cloth bucket in the moving direction of the grid is less than 1.2 cm, when the former cloth space is clothed to the grid, the latter cloth is left. There will also be a small amount of powder into the grid. Grid

Replacement page (Article 26) This supplements the lack of cloth in the previous cloth space and affects the cloth effect; and when the width of the space in the cloth bucket in the moving direction is greater than 1.2 cm, the powder in the cloth space will produce a certain amount during the cloth bucket process. The degree of mixing, the greater the width, the more the powder in the cloth space is mixed, the worse the role of the cloth bucket in regularly arranging the powder in the grid.

As analyzed above, the width of each cloth space in the cloth bucket in the grid moving direction has an influence on the cloth cloth cloth effect. To determine the width of the cloth space, the following tests were performed. The test uses the same grid, the same powder, and the same grid moving speed. The distribution of the powder in each cloth space is also the same. The cloth bucket is shown in Figure 4, and only the cloth space inside the cloth bucket is changed. The width of the grid moving direction.

As shown in Table 1, when the width is greater than 4h, the effect of the interval cloth bucket is already small. When the width is less than or equal to 4h, it is effective. When the width is less than or equal to 3h, it has a better effect. (Article 26) The effect is better when the degree is less than or equal to 2h, and the effect is better when the width is less than or equal to h. The effect mentioned here refers to the sharpness of the pattern.

According to the design requirements of the brick surface pattern, part of the cloth space in the cloth bucket can be made narrower and part of the cloth space is wider. In this way, the fine stripe pattern on the tile surface is partially clear and partially fuzzy.

It is not difficult to understand that ¾1 is necessary. The inside of the cloth bucket can also be separated by other curved materials or other methods. The connection between the spacer material and the outer wall of the cloth bucket can also be movable; it can also be spaced in the direction of the grid movement. After that, space them in the direction perpendicular to the grid movement, or use another shape cloth bucket.

In the cloth bucket shown in FIG. 4, the width of each cloth space in the direction of the grid movement may also be less than or equal to 3.8 times or 2.8 times or 1.8 times or 0.6 times of the grid height.

The cloth bucket shown in FIG. 6 is composed of four walls, which are open up and down, and the two walls are vertically parallel to the moving direction of the grid; one wall is vertically connected to the two walls, and the other is vertically inclined downward and inwardly. The two walls are vertically connected. The cloth bucket is fixedly spaced into 4 cloth spaces by vertical boards in the direction of the grid movement. The width of each cloth space in the grid movement direction is less than or equal to 3.3 times the grid height or 2.3 times or 1.3 times or 0.5 times.

Figure 7 shows a cloth bucket that is open up and down and is vertically connected by three vertical planes and a plane inclined inwardly downwards. In the direction of the grid movement, its internal width is less than or equal to the height of the grid 3.5 times or 2.5 times or 1.5 times or 0.7 times.

1 in FIG. 8 and FIG. 9 is an example of the powder box of the feeder provided by the present invention. It is a rectangular box with a bottom. The top is open, and the inside of the box is separated from the space in the cloth bucket. Corresponding rows of multiple feeding spaces-squares (8 squares in this example), the bottom of each square is part of the bottom of the powder box, and the bottom of each square has Rectangles of different sizes

8

Replacement page (Article 26) Each type of powder is lowered into each square through the discharge tube. One square is next to the powder. When the powder box is moved over the cloth hopper, the powder in each square passes at the same time. The feeding openings flow into the corresponding cloth space of the cloth hopper in turn, and feed various powders to the cloth hopper one by one. The width of each feeding opening in the direction of the feeder's movement varies, which determines the various grids. The thickness of the powder in the cloth bucket varies; by designing the grid arrangement in the powder box, the shape and size of the feeding opening, and the placement of various powders in the grid, it can be divided into layers according to the design requirements. Various powders are fed into each cloth space of the cloth bucket in a space-wise manner. The feeding opening can also be other shapes other than rectangular, and its position and shape are determined according to the design. The area of the feeding opening is smaller than the area of the bottom of the feeding space where the feeding opening is located. It is not difficult to understand that the powder box can also be a bottomed container of other shapes. For example, the upper part of the powder box spreads upwards and outwards, so that the opening of the powder box and various squares is enlarged, so that the powder flows in; or The upper part of the material box is covered, and there is a feed inlet; the feeding space in the powder box can also be spaced into other shapes according to the design requirements; In addition, the bottom of the powder box and the box body can also be movably connected . Because when the above powder box is moved above the cloth hopper, how many feeding spaces there are in the powder box, how many different kinds of powders are fed into the cloth hopper at the same time, so the feeding speed is Can be several times or even ten times higher than the existing ti feeder.

The cloth distributing device of the present invention can also be equipped with other feeders not included in the cloth distributing device of the present invention. The feeder can feed various powders layer by layer and space into the cloth buckets according to the design requirements. in.

In the cloth moving device of the present invention, in the direction of the grid movement, a plurality of cloth buckets not less than two can be arranged side by side. A corresponding feeder can be arranged on the cloth bucket, and each cloth bucket is simultaneously or wheeled.
