Description

Technical Field

[0001] The invention relates to the technical field of tile glazing, and in particular to a thin tile glazing method and a thin tile glazing system. Background Art

[0002] Tile glazing refers to applying glaze to the surface of the tile, which generally includes processes such as applying glaze and drying and curing.

[0003] At present, conventional glazing methods include dipping, swinging, spraying and pressing, etc. After long-term development, the above glazing methods have become relatively mature. However, with the continuous development of tile manufacturing technology and the continuous improvement of tile quality requirements, the existing glazing methods still need to be improved.

[0004] For example, if conventional glazing methods are used to glaze thin bricks with a thickness of 3mm-9mm currently on the market, the glazing quality will not meet the requirements. In many cases, this is because the thin bricks are thin, the glaze thickness ratio is high, and too much moisture in the glaze penetrates into the thin bricks, causing the moisture in the thin bricks to exceed the standard, affecting subsequent processes or the final thin brick quality does not meet the requirements.

[0005] Therefore, it is necessary to propose improvements for the problems existing in the prior art. Summary of the invention

[0006] The purpose of the present invention is to provide a thin brick glazing method and a thin brick glazing system, aiming to solve the problem that the glazing method in the prior art is prone to excessive moisture when glazing thin bricks.

[0007] In order to achieve one of the above-mentioned purposes, the present invention provides a thin brick glazing method, the thickness of the thin brick is 3mm-9mm, the thin brick glazing method includes glazing the thin brick more than twice, each glazing includes a roller glazing process and a drying process performed before and after, and the roller glazing process adopts a roller glazing method to perform glazing.

[0008] Furthermore, in the roller glazing process, the glazing amount is 5-30 g / m 2 .

[0009] Furthermore, in the drying process, hot air drying or thermal infrared drying is adopted, the drying temperature is 60-120°C, the conveying speed of the thin bricks during drying is 10-32m / min, the drying length is 1.6-3.5m, and the air in the drying box is dehumidified during the drying process.

[0010] Furthermore, a cooling process is provided between two adjacent glazing processes, during which the temperature of the thin bricks does not exceed 80°C.

[0011] Further, the amount of glazing applied in the latter time is greater than or equal to the amount of glazing applied in the previous time, the drying temperature in the latter time is higher than or equal to the drying temperature in the previous time, and the drying time in the latter time is shorter than or equal to the drying time in the previous time.

[0012] In order to achieve the second of the above-mentioned purposes, the present invention provides a thin brick glazing system for implementing the above-mentioned thin brick glazing method, which includes a conveying device and at least two groups of glazing and drying modules. The conveying device forms a thin brick conveying path, and each group of the glazing and drying modules includes a glaze rolling device and a drying box arranged before and after the thin brick conveying path. On the thin brick conveying path, the at least two groups of glazing and drying modules are arranged in sequence.

[0013] Furthermore, the glaze rolling equipment and the drying box are both mounted on the conveying equipment.

[0014] The thin brick glazing method provided by the present invention is glazed by roller glazing compared with the prior art. Based on the roller glazing method, the thickness of each glazing can be controlled to be thinner and thinner than the conventional glazing method. The thinner glaze can reduce the water content in the glaze from penetrating into the thin brick. After each glazing, a drying process is performed, so that the glaze applied this time can be dried first. The glaze dried first can also block the water content of the glaze applied subsequently from entering the thin brick, so that the water content finally entering the thin brick meets the standard. After one glazing, the next one is performed. According to the requirement of the glazing amount, the glazing amount of the conventional glazing method is divided into two or more times, and after superposition, the final glaze layer thickness meets the requirement. Therefore, the thin brick glazing method can be used to glaze the thin brick, which can ensure the glazing amount while avoiding excessive water penetration into the thin brick and affecting the subsequent process or the quality of the finished product.

[0020] The present invention is described in detail below in conjunction with specific embodiments.

[0021] In the present invention, when directional words appear, they are used to facilitate the description of the present invention and simplify the description, rather than to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present invention. In the present invention, unless otherwise clearly specified and limited, when terms such as "disposed on", "connected", and "connected" appear, these terms should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or the two elements can be internally connected. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0022] Thin brick glazing method

[0023] The present invention provides a thin brick glazing method, wherein the thickness of the thin brick referred to in the present application is 3mm-9mm. The thin brick glazing method comprises glazing the thin brick more than twice, wherein each glazing comprises a roller glazing process and a drying process, and the roller glazing process is performed by roller glazing.

[0024] The thin brick glazing method provided by the present invention performs glazing by roller glazing. Based on the roller glazing method, the thickness of each glazing can be controlled to be thinner and thinner than the conventional glazing method. The thinner glaze can reduce the water in the glaze from penetrating into the thin brick. A drying process is performed after each glazing, so that the glaze applied this time can be dried first. The glaze dried first can also block the water in the subsequently applied glaze from entering the thin brick, so that the water content finally entering the thin brick meets the standard. After one glazing is completed, the next one is performed. According to the requirement of the glazing amount, the amount of glazing applied once by the conventional glazing method is divided into two or more times, and after superposition, the thickness of the final glaze layer meets the requirement.

[0025] Preferably, the amount of glazing applied in the latter time is greater than or equal to the amount of glazing applied in the previous time, the drying temperature in the latter time is higher than or equal to the drying temperature in the previous time, and the drying time in the latter time is shorter than or equal to the drying time in the previous time. Since the glaze layer of the first glazing has a protective effect on the tiles, the amount of glazing can be increased in the subsequent glazing process. At the same time, in order to improve production efficiency, the drying temperature can be increased and the drying time can be shortened accordingly. Of course, it is also possible for the parameters of each glazing to be partially consistent, completely consistent, reduced in sequence or increased in sequence. Under the guidance of the method principle of the present invention, technicians can adjust the above parameters according to actual production conditions.

[0026] Preferably, the drying is performed by hot air drying or thermal infrared drying, and the air in the drying box is dehumidified during the drying process.
