Description

Ceramic tile double-distribution equipment and method, and products produced

The invention relates to a system or equipment for producing building ceramic tiles, a method for producing ceramic tiles using the system, and a ceramic tile produced by using the system and method. More specifically, the present invention relates to a ceramic tile double cloth system and cloth method, in particular to a double cloth system and cloth method of ceramic tiles that imitate natural stone patterns, and ceramics that mimic natural stone patterns produced by using the system and method. brick. Background technique

In the building materials ceramics market in recent years, users hope to obtain ceramic tiles with natural texture, look, feel, and realism, and at the same time, they want low prices and eliminate certain defects of natural stone. Through multi-layer cloth, one-time mold filling, and pressed ceramic tiles, the color tone is flexible and the color is rich, and the color of natural stone can be approximated on the level of physical essence. The ceramic tile double cloth is based on the simulation of natural stone. While retaining the strength and polishability of the ore, it can overcome the defects such as radioactive contamination and natural cracks of natural stone such as marble and granite.

At present, the emphasis of different multi-layer cloth distribution systems is different, and the functions that the system can achieve are also different. For example, a multi-tube distribution system is roughly composed of a system support frame, a movable frame with a grill, a distribution trolley, a sleeve supplying powder and various mixtures, a distribution sports car, a sleeve driving system, and a moving material. Box-driven system. When the powders of different colors pass through the sleeve of the powder supply, they form an irregular mixed-color powder and fall into the cloth trolley. Driven by the moving material frame drive system, the movable frame can move forward while the powder of the cloth trolley The material falls into the material frame until it is sent to the cavity of the press mold, completing the work of "feeding to the press once". The press enters the compaction and turns the powder into brick. In this process, the movable material frame has a built-in "grid" device, so that the powder can form a dynamically variable, whole-body pattern under the action of the grid during the feeding process. This pattern is subject to the pattern regularity and direction of the "grid", which can achieve macroscopic repetitive yet changing visual effects. But the fine lines of stone texture and stable, repeatable patterns cannot be formed.

The secondary distribution system generally includes the system support frame, the bottom "base material" moving material frame (including the grille), the cloth basic material trolley, the supply of basic powder sleeves, the sleeve drive system, the material trolley, and the mobile material frame drive system. , Micro powder feeding sleeve, pneumatic vibrator and cloth micro powder sports car. Replacement page (Article 26) The "basic spray powder" falls into the cloth basic material cart through the supply of the basic powder sleeve. When the mobile material frame drive system drives the bottom "base material" mobile material frame (built-in grille to prevent powder from rolling), it moves forward until The basic powder is fed into the cavity of the press to realize the first distribution. After that, the lower core of the press mold is lowered again, forming a "second cloth" cavity. The micro-powder cloth trolley is driven forward by the drive of the moving material frame driving system, and the gate is opened. The micro-powder is clothed on the upper surface of the press mold cavity under the action of the pneumatic vibrator. This completes the "second cloth" job. This way of working is essentially feeding a second layer of micropowder material (finer granularity and containing chemical pigments) on the first base powder layer, forming a pattern during the feeding and feeding process, and each material is calcined in ceramics Combined under the craft. The pattern has low predictability and accuracy, and cannot meet the requirements of complete man-made and change with points. It cannot meticulously trace the complex patterns on the surface of natural stone, and cannot generate floor tiles with regional and color contrast discretization effects.

It has several working silos, control belts, secondary and tertiary hoppers and feeding hoses connected in order from top to bottom.

The lateral conveying mechanisms 104 and 105 are provided with an adjustable fixing limit mechanism 132 to limit the position of the material cavity when it is moved. There are 8 (but not limited to) material chamber positions 107, 108, 109, 110, 114, 115, 116 and 117 on the longitudinal conveying mechanisms 102 and 103. At least one material cavity can be placed in each material cavity position. Take one material cavity for each material cavity as an example.
