Description

Ceramic tile back sizing device Technical Field The invention relates to the technical field of building ceramics, in particular to a ceramic tile back sizing device. Background In order to reduce the production cost, in the production process of ceramic tiles, the surface layer of the ceramic tile blank often uses ceramic powder produced by better raw materials because of bearing the decoration effect, and the bottom layer generally adopts ceramic powder produced by cheap raw materials (low-cost raw materials). The ceramic tile produced by adopting cheap raw materials has lower whiteness, roughness and lower strength on the back, and the specific reasons are shown in a method and a blank bottom slurry spraying system for strengthening, toughening and whitening the bottom of the ceramic tile, which are disclosed in the application number 2025104976393 of the inventor in 2025, 04 and 21, wherein the reasons generated in the background technology are discussed in detail. The blacker and rough ceramic tile back can greatly influence the grade of ceramic products, and when a common consumer purchases the ceramic tile, the blacker ceramic tile back can be considered to have poor quality, so that the sales of the products are influenced. In order to solve the problem, the inventor proposes that the ceramic green body is coated with the ceramic green body whitening slurry, so that on one hand, the whiteness of the back surface of the ceramic brick can be well improved, the whitening purpose is achieved, and the attractive degree of a product is improved, and on the other hand, after the ceramic green body is coated with the ceramic green body whitening slurry, the ceramic green body whitening slurry can permeate into pores of the back surface of the ceramic brick, so that the roughness of the bottom can be remarkably improved, the attractive degree of the back surface of the ceramic brick is improved, and the market attraction of the product is enhanced. The blank bottom slurry spraying system comprises a first ceramic tile blank turning device, a slurry spraying device and a second ceramic tile blank turning device which are sequentially connected through a conveying line. The slurry sprayed by the slurry spraying device is the ceramic blank bottom whitening slurry. The slurry spraying system can well spray the whitening slurry on the back surface of the ceramic tile blank in actual production. However, the following problems are also present: 1. the blank bottom slurry spraying system adopts two blank turning devices (namely a first ceramic tile blank turning device and a second ceramic tile blank turning device) to realize the turning and restoration of ceramic tile blanks, so that the equipment investment cost is higher; 2. two blank turning devices are adopted, the occupied area of equipment is large, and one blank turning device occupies about 15 square meters of space in the actual production process, so that the production site cost is high; 3. the production speed is slower by adopting the procedures of turning, slurry spraying and turning and recovering. Therefore, the scheme of turning over the ceramic tile and then spraying slurry on the bottom surface is adopted, so that the overall cost is high. In the prior art, other schemes without turning over are adopted, such as China patent number 202123156801.1, named as tile sizing device, which adopts a first sizing roller and other sizing rollers to directly distribute the sizing under the condition that the tile is not turned over. But it is mainly used for coating alumina slurry, and the purpose is to avoid the ceramic tile blank body from being stuck on the roller rod in the tunnel kiln. However, this solution is not suitable for the situation that the back surface of the ceramic tile needs to be uniformly sized, because in order to improve the adhesion force during paving, the back surface of the ceramic tile is generally provided with lines, so that a concave-convex bottom surface is formed, only the convex part can be sized by using the pulp distribution roller, and the concave part cannot be sized because the pulp distribution roller is not contacted, but the concave part is not contacted with the roller rod in the tunnel kiln, so that no problem exists. It can be seen that the prior art solutions do not solve the problem of completely sizing the back side of the ceramic tile. Therefore, there is a need to develop a new device to solve the problems of high cost, large occupied area, slow production speed or inability to completely slurry the back surface of ceramic tiles in the existing slurry spraying system. Disclosure of Invention The invention provides a ceramic tile back surface sizing device, which aims to solve the problems of high cost, large occupied area, low production speed or incapability of completely sizing the back surface of a ceramic tile in the existing slurry spraying system. In order to achieve the functions, the technical schem
