Description
Technical Field
The invention relates to the technical field of ceramic tiles, in particular to a ceramic tile printing method based on code spraying identification.
Background
In order to meet the requirements of decoration effect of ceramic tiles in modern life, the prior art provides ceramic tiles printed with patterns, and the patterns formed by printing the ceramic tiles can show better decoration effect. If unit patterns are printed on the ceramic tiles, the ceramic tiles can be mutually connected to form a smooth, coherent and regular integral pattern decoration effect. Therefore, printing patterns on the ceramic tiles also becomes a common processing method in the production of various ceramic tiles in the prior art.
However, the production method, which is more common in the prior art, includes the steps of: the targeted pattern printing cannot be realized by press forming, glazing, pattern printing and sintering. That is, the ceramic tile blank is usually produced by adopting a flow line production mode, and a single pattern is printed on the ceramic tile blank which is not processed or is processed, so that the diversity of the pattern cannot be realized. Even if different patterns are printed on the ceramic tile blank in a single production line, the patterns are often selected and printed blindly, further targeted pattern formation cannot be realized by combining the characteristics of the ceramic tile blank, and more diversified and diversified ceramic tile decoration effects cannot be realized based on the targeted pattern formation.
Disclosure of Invention
The invention aims to overcome at least one defect of the prior art, and provides a ceramic tile printing method based on code-spraying identification, which can print corresponding patterns on a ceramic tile blank according to the appearance characteristics of the ceramic tile blank reflected by an identification code, so that the targeted pattern formation is realized, the ceramic tile has the decorative effect formed by matching the patterns with the ceramic tile blank besides the decorative effect of the patterns, and the decorative effect of a ceramic tile finished product can be obviously improved.
The invention adopts the technical scheme that a ceramic tile printing method based on code spraying identification comprises the following steps:
s1, applying a computer-recognizable identification code to the tile blank, wherein the identification code reflects information including the appearance of the tile blank; the ceramic tile blank has an appearance formed correspondingly after being formed or processed, and appearance information can be contained by applying the identification code, so that a subsequent printing device is facilitated to print a corresponding pattern according to the appearance of the ceramic tile blank. The appearance of the ceramic tile blank comprises the shape of the ceramic tile blank, whether glaze is applied and the color of the applied glaze, and the application of the identification code before pattern printing is helpful for printing the pattern by combining the shape of the ceramic tile blank and the glaze in a targeted manner, so that the matching effect of the pattern and the ceramic tile blank is achieved. The appearance effect generated in the step of forming or processing the ceramic tile blank is also obtained before the identification code is applied, so that the corresponding identification code can be rapidly set and applied to the ceramic tile blank when the ceramic tile blank reaches the identification code application position; the identification code is formed on the ceramic tile blank in a spray painting mode;
s2, identifying the identification code to obtain information reflected by the identification code; after the identification code is applied to the ceramic tile blank body, the identification code is required to be identified before the printing device prints, the appearance information of the ceramic tile blank body reflected by the identification code can be accurately obtained through computer identification, and compared with the method that the information is directly transmitted to the printing device when the identification code is applied, the possibility of generating subsequent waste plates can be reduced; because the tiles are often driven for a long distance from one step to the next during the production process, waste boards may be produced during the process; if the information is directly transmitted to the printing device when the identification code is applied, the subsequent patterns can be continuously printed on the corresponding ceramic tile blank due to the fact that the waste board is generated midway and is removed, and a large amount of waste boards are generated; the independent operation of applying the identification code and the identification code can at least avoid the influence of the waste board between the step S1 and the step S2 on the subsequent steps, and the independent identification code step is favorable for reducing the requirement of the corresponding equipment and simplifying the operation difficulty of the equipment; more preferably, the printing device is provided with an identification module, the printing device acquires information reflected by the identification code through the identification module, and the influence of the waste board in the processes from S1 to S3 can be further avoided through the method;
and S3, the printing device calls a corresponding pattern according to the information acquired in the step S2 and prints the pattern on the tile blank. The printing device obtains the information which reflects the appearance of the ceramic tile blank, then calls the corresponding pattern in the printing device system and prints the pattern, so that the targeted pattern printing is realized, the printed pattern can be matched with the ceramic tile blank, and the harmonious feeling of ceramic tile decoration is improved. And the printed patterns can be matched with the unfinished or processed ceramic tile blank on the basis of the patterns to form a more multi-level decorative effect.
Compared with the prior art, the mode that this application adopted the identification code after the ceramic tile idiosome formed or processed after to mark the ceramic tile idiosome, help follow-up course of working including the printing process to acquire corresponding ceramic tile idiosome outward appearance information according to the identification code to the pertinence carries out corresponding processing, then according to the ceramic tile idiosome outward appearance information formation that the identification code reflects to printing device on corresponding pattern and the ceramic tile idiosome, thereby realize the pattern printing of pertinence. The ceramic tile blank has the advantages that the patterns and the ceramic tile blank can be matched with each other in appearance, the matching decorative effect except the independent pattern decorative effect is realized, the consistency of the appearance of the ceramic tile blank and the surface patterns is kept, the harmonious feeling and artistic feeling embodied by matching the ceramic tile blank and the patterns are improved, and the decorative effect of the ceramic tile as a decoration material is improved.
Simultaneously, help improving the situation that the ceramic tile production process can't produce multiple style ceramic tile on solitary production line among the prior art based on the identification code, because printing device can carry out corresponding printing according to the identification code, can utilize the production of multiple style ceramic tile in the identification code realization production line on this basis, provide more extensive selection for the user, satisfy the demand of modern fitment to the ceramic tile style. And when guaranteeing the variety of production ceramic tile, do not disturb the continuation of production process and go on, guaranteed production efficiency when richening the ceramic tile pattern promptly, help putting into production line and carry out the batch production of ceramic tile in fact. In addition, the identification code is adopted for identification, so that the surface pattern can accurately correspond to the ceramic tile blank with a specific appearance, and the expansion of the printed pattern can be conveniently made according to the identification code; so that the printing patterns can be changed or added in time according to the requirements, and the production process of the ceramic tile is more flexible.
Preferably, an identification code is applied to the front surface of the tile blank in step S1, the identification code being formed by an organic solvent applied to the tile blank; and/or, the identification code is applied to the side or back of the tile blank in step S1. When the identification code is applied to the front surface of the ceramic tile blank, the application position with a larger area is provided, so that the application of the identification code is convenient; meanwhile, since the ceramic tile is required to be fired subsequently after the pattern is printed, namely the ceramic tile is required to be fired after the step S3, the organic solvent is adopted, so that the influence on the surface of the ceramic tile and the pattern printed on the ceramic tile when the organic solvent is applied to the front surface can be avoided; since the organic solvent can be volatilized during firing and does not remain. When the identification code is applied to the side face or the back face of the ceramic tile blank, the subsequent processing process on the front face of the ceramic tile cannot be influenced, and the influence on the decorative effect of the ceramic tile is small. Therefore, when the identification code is applied to the side face or the back face of the tile body, the subsequent processing process and the decoration effect are not influenced by adopting the organic solvent or the non-organic solvent. And when the identification code is applied to the side surface, the arrangement of the device for correspondingly applying the identification code is facilitated, and the subsequent identification of the identification code is also facilitated. The front surface of the ceramic tile blank is the decoration surface and the glazing surface of the ceramic tile, and the back surface of the ceramic tile blank is the surface on the opposite side of the front surface.
More preferably, the identification code is applied to the side of the tile blank parallel to the direction of transport of the tile blank in step S1. The identification code is applied to the side face parallel to the transmission direction, the identification code is facilitated to be correspondingly applied to the two sides of the transmission direction of the production line by the application device, so that the non-deformable and regular identification code is conveniently applied when the ceramic tile blank reaches the application position of the identification code, and the application difficulty of the identification code is reduced. When the identification code is applied to other side surfaces, such as the side surface facing the transmission direction, the difficulty of arrangement of the identification code applying device is increased, the influence of the positions of other devices including the transmission device is limited, and when the orientation of the identification code applying device is not in the same plane position with the side surface, the identification code which is not deformed and regular is difficult to print, so that the difficulty of applying the identification code is increased. Applying the identification code on a side parallel to the transport direction also facilitates subsequent handling of the identification code, facilitating the arrangement and identification of the device or module for identifying the identification code.
More preferably, when the identification code is applied to the side of the tile blank, the tile blank is further subjected to side grinding after the printing in step S3 is completed. When the identification code is applied to the side of the ceramic tile blank, the identification code can be formed by adopting a non-organic solvent, the identification code can be removed by adopting a polishing mode in order to avoid the residue of the identification code, and the production of the whole ceramic tile finished product with clean appearance is facilitated.
Preferably, the tile blank comprises a tile body, and before the step S1, the method further comprises the steps of:
a. processing the raw materials and then performing compression molding treatment to obtain a compression-molded ceramic tile body; pressing the processed raw materials, namely pressing the blank powder, so as to form a formed ceramic tile body;
b. carrying out texture processing on the ceramic tile body to form a texture pattern comprising more than one concave texture and/or convex texture, wherein the concave texture is formed by applying a reaction substance to corrode the surface to be subjected to texture application, and the convex texture is formed by stacking a non-corrosive substance on the surface to be subjected to texture application; in the traditional ceramic tile production process, namely, in the step a, the raw materials are directly pressed and processed by a press capable of generating a die effect to form a ceramic tile body with the die effect, namely the ceramic tile body with textures; the ceramic tile is characterized in that the ceramic tile body is formed by pressing the ceramic tile body through a pressing machine, and then the texture is processed, so that the subsequent processing is facilitated to form the texture which shows nature. Compared with the mold effect formed by pressing powder by using a press or harder convex ribs or grooves in a mold connected with the press in the traditional ceramic tile production, the mold effect formed by erosion or stacking of substances does not appear to be harsh, and the ceramic tile decoration effect of natural cracks and bumps can be generated. The texture processing after the ceramic tile body is formed can conveniently form different textures among different ceramic tile bodies, and not all the ceramic tile bodies have the same mold effect under the action of a press or a mold connected with the press;
the identification code applied in step S1 reflects at least the texture pattern information of the current texture formation. The identification code reflects the appearance information including the texture, so that the subsequent printing device can print corresponding patterns according to the identification code, the surface printed patterns have consistency with the texture, and the decorative effect and the ornamental experience of a user are improved.
Adopt solitary texture course of working, so be convenient for process and produce comparatively diversified texture pattern for the ceramic tile of production has abundant pattern, helps providing more extensive selection for the user, satisfies the demand of modern fitment to the ceramic tile pattern. When guaranteeing the variety of production ceramic tile texture pattern, do not disturb the continuation of production process and go on, guaranteed production efficiency when richening the ceramic tile pattern promptly, help carrying out the batch production of ceramic tile on the actual input production line. Importantly, besides improving the effect of the texture pattern and promoting production and application, the production method of the ceramic tile can also enable the surface pattern printed on the ceramic tile blank to correspond to the texture pattern of the ceramic tile blank, so that the consistency of the texture pattern and the surface pattern is kept, the harmonious feeling and artistic feeling embodied when the texture pattern and the surface pattern are combined are improved, and the decorative effect of the ceramic tile as a decoration material is improved.
More preferably, the step a is carried out drying after the blank is pressed and formed; step b is also followed by texture processing and drying.
More preferably, step S1 is performed before the identification code is applied to detect whether the texture processing is completed, so as to facilitate the application of the computer-recognizable identification code to the tile blank body on which the texture processing is completed;
preferably, the texture processing is carried out through a digital mould, the identification code is printed through a code printer for identification, the identification is identified through an identification device, and the pattern printing is carried out through an ink-jet printer; the ink jet printer is connected with the identification device, and prints patterns after acquiring identification information of the identification device.
Preferably, more than one raised texture and/or depressed texture is randomly selected in the step b to process the texture of the blank; step S1 acquires the texture pattern formed in step b and applies an identification code. In addition to being processed on the basis of various fixed texture patterns corresponding to the ceramic tile blank body, the random texture patterns can be obtained by randomly selecting more than one existing raised texture and/or sunken texture for processing and matching, so that the textures expressed on the ceramic tile have the characteristic of randomness, the expressed texture patterns are more natural, and the decorative effect of the ceramic tile based on the textures is further enhanced. Meanwhile, the texture and the texture pattern applied to the tile in the step b can be obtained in the step S1, so that the texture and the texture pattern can still be identified, and thus the pattern can be printed according to the identification code to ensure that the printed pattern corresponds to the texture.
More preferably, the mark comprises a fixed mark and an expansion mark, the fixed mark reflects the current blank texture pattern information, and the expansion mark reflects the pattern to be printed in combination with the fixed mark. The fixed mark reflects the current texture pattern, so that the step S3 is convenient to print corresponding patterns according to the fixed mark, and the one-to-one correspondence between the printed patterns and the texture patterns can be realized; and the expansion mark is arranged on the basis of the fixed mark, so that the expansion of the printing patterns of the same texture pattern can be realized by combining the fixed mark, namely, the expansion of the printing patterns of the same texture pattern blank can be realized by combining the fixed mark and the expansion mark in the step S3, so that the tile has richer styles. More preferably, the extension mark comprises a special mark, and when the extension mark is the special mark, the corresponding printing pattern is the same as the printing pattern corresponding to the fixed mark.
Preferably, step S1 is executed synchronously during the step b of texture patterning or immediately after the blank texture patterning is completed. Since the tile is moved a long distance between the steps to control the water content, and may be wasted, if the texture pattern information is directly transmitted to the printing process after the texture pattern is formed, the situation that the printing surface pattern is wrongly printed due to the wasted board is generated midway, so that the texture pattern of the blank does not correspond to the surface printing pattern, and a large amount of wasted boards are generated. For example, after the original texture pattern is processed on the a board, step S3 is ready to identify the a board as two square codes, and when the a board is scrapped before identification, the two square codes may not be printed on the a board but printed on the B board that should be identified as two circular codes, so that the B board is printed with a surface pattern that does not correspond to the texture pattern of the B board, and then a misprint may be continuously formed, resulting in a large amount of waste boards, which results in waste of cost, material and time. And the problems can be avoided by synchronously executing the blank texture pattern or immediately executing the blank texture pattern after the texture pattern is formed, so that the accuracy of the identification is ensured, and the subsequent continuous correct printing is ensured.
Preferably, in step b, the texture is formed by a printing mode that a plurality of jet holes of the digital mould printing head jet out corresponding substances to the surface to be textured, the tile blank moves relative to the digital mould printing head and is printed when passing through the mould printing head, and step S1 is to apply the identification code according to the processing texture information transmitted by the digital mould. The mould beats printer head and forms a plurality of printing points on the ceramic tile idiosome, and a plurality of thing points that spout promptly to the processing of texture is realized to the printing mode, can accurate control material quantity and material placement to output anticipated texture pattern and texture effect. In addition, in order to facilitate the correspondence between the identification code and the texture pattern, the texture information can be transmitted simultaneously when the printing head of the mold prints, so that the identification code can be quickly applied after being processed during texture processing, and the identification code can be conveniently corresponded to the finally formed texture pattern when randomly selected textures are applied.
Preferably, a ground coat is further applied to the ceramic tile body to form a ground coat layer before texture processing in the step b, the ceramic tile blank body comprises the ceramic tile body and the ground coat layer, the identification code is applied to the ground coat layer, and the identification code is formed by adopting an organic solvent for spray painting; and in the step b, the texture is processed on the ceramic tile blank with the ground glaze. Applying the ground glaze on the ceramic tile body is beneficial to forming the ground color of the blank body so as to produce the ceramic tile with the specific ground color according to the requirement; therefore, correspondingly, on the premise of having the ground glaze, the identification code can be applied to the ground glaze, but the ground glaze is not necessary for the ceramic tile, so when the ceramic tile does not have the ground glaze, and when the texture is directly formed on the ceramic tile body, the identification code can be directly applied to the ceramic tile body.
Preferably, between the steps S1 and S3, a cover glaze is applied to the tile blank, and the printing device prints a corresponding pattern on the cover glaze according to the information reflected by the identification code. The printing patterns are arranged on the overglaze, so that the patterns can be clearly printed, the formation of the printing patterns is facilitated, the fine and smooth patterns can be displayed, and the decorative effect of the ceramic tile is improved.
More preferably, after the pattern is printed in step S3, a protective glaze is further applied to the blank. The method is beneficial to keeping the printed surface pattern clear, protecting and improving the color development capability of the ink and ensuring the pure color development.
Preferably, the identification code is recognized by the recognition means including the image recognition means or the scanning means and the recognition information is transmitted to the printing means in step S2. That is, in step S2, the identification code is identified by image recognition and/or code scanning recognition, and the scanning device may be a laser scanning device. More preferably, the identification means is a module of the printing apparatus, which helps to reduce the impact of identifying waste sheets during printing. More preferably, the identification code is identified by an image identification device, and compared with a scanning device, the image identification is more accurate and is less interfered.
More preferably, the identification means is oriented perpendicularly to the face of application of the identification code. The recognition face of the recognition device is parallel to the application face of the recognition code, the recognition device is beneficial to quickly recognizing the recognition code on the plane on which the recognition code is applied to the ceramic tile, the recognition difficulty is obviously reduced, the data calculation amount in the recognition process is reduced, and the recognition accuracy and the recognition speed are always kept in the continuous production process.
Preferably, the identification code comprises more than one geometric pattern and/or number and/or letter; the width and height of the identification code are all larger than 0.5 cm. The ceramic tile blank is marked by adopting common geometric patterns, numbers and/or letters, the marking mode is simple, the application of the identification code is convenient, and the ceramic tile blank is also beneficial to manually maintaining or monitoring the correspondence between the ceramic tile blank applied with the identification code and the printing pattern in the production process. In addition, the identification code can also be a two-dimensional code, and the information contained in the two-dimensional code is richer compared with a simple pattern; however, applying the two-dimensional code requires high precision of the identification code applying device, and therefore, it is more preferable to select a relatively common pattern as the identification code. Under adverse circumstances, the discernment of identifying code can receive the influence, sets up the great degree of difficulty that then can reduce the discernment with the identifying code size to help the accurate discernment of identifying code, make also can be by quick, accurate discernment under the adverse circumstances, thereby be convenient for improve the precision that printed pattern and identifying code correspond, improve final ceramic tile yield. And the thickness of the common ceramic tile is usually more than or equal to 7.5mm, the width and the height of the identification code are all 0.5cm, the identification code can be arranged on the front surface, the back surface and the side surface of the ceramic tile, and the condition of difficult identification caused by the environment is favorably overcome due to the adoption of simple patterns. More preferably, when the identification code is arranged on the front surface of the ceramic tile, the width and the height of the identification code are both larger than 2 cm.
Compared with the prior art, the invention has the beneficial effects that: the ceramic tile blank has the advantages that the targeted pattern formation is realized, the corresponding pattern can be applied according to the appearance characteristics of the ceramic tile blank, so that the ceramic tile has the decorative effect formed by matching the pattern and the ceramic tile blank except the decorative effect of the pattern, and the decorative effect of the ceramic tile finished product can be obviously improved. The appearance characteristics of the ceramic tile blank body comprise texture processing before the identification code is applied, and the decorative effect of the ceramic tile can be improved by forming more natural textures through erosion or stacking. The ceramic tile code spraying, identifying and printing method can also enable the surface patterns printed on the blank body to correspond to the texture patterns of the blank body, so that the correspondence between the texture patterns and the surface patterns is maintained, and the decorative effect of the ceramic tile as a decoration material is further improved. Meanwhile, the printing by the code spraying identification mode is also beneficial to enriching the production diversity of the ceramic tiles while keeping continuous production, for example, different identification codes are applied to different ceramic tiles on the same production line, the ceramic tiles with different patterns can be pertinently produced without an additional production line, more production equipment can be prevented from being installed for producing the ceramic tiles with different patterns, and the cost required for producing the products with the same patterns is obviously reduced. The diversified ceramic tiles can provide wider choices for users, and meet the requirements of modern decoration on ceramic tile styles. In addition, the identification code is adopted for identification, so that the surface pattern can accurately correspond to the ceramic tile blank with a specific appearance, and the expansion of the printed pattern can be conveniently made according to the identification code; so that the printing patterns can be changed or increased in time according to the requirements, the production process of the ceramic tile is more flexible, and the production of the ceramic tile also has expansibility.

3. The method for printing ceramic tiles based on code-spraying identification as claimed in claim 1, wherein the ceramic tile blank comprises a ceramic tile body, and before the step S1, the method further comprises the steps of:
a. processing the raw materials and then performing compression molding treatment to obtain a compression-molded ceramic tile body;
b. carrying out texture processing on the ceramic tile body to form a texture pattern comprising more than one concave texture and/or convex texture, wherein the concave texture is formed by applying a reaction substance to corrode the surface to be subjected to texture application, and the convex texture is formed by stacking a non-corrosive substance on the surface to be subjected to texture application;
the identification code applied in step S1 reflects at least the texture pattern information of the current texture formation.
4. The method for printing ceramic tiles based on code-spraying identification as claimed in claim 3, wherein step S1 is executed synchronously during the step b of forming the texture pattern or immediately after the blank texture pattern is formed completely.
5. The tile printing method based on code spraying identification as claimed in claim 3, wherein more than one concave texture and/or convex texture is randomly selected in step b for texture processing of the blank; step S1 acquires the texture pattern formed in step b and applies an identification code.
6. The method for printing ceramic tiles based on inkjet recognition as claimed in claim 3, wherein the texture is formed in step b by a digital mold printing head with multiple nozzles ejecting corresponding substances onto the surface to be textured, the ceramic tile body moves relative to the digital mold printing head and is printed while passing through the mold printing head, and step S1 is performed to apply the recognition code according to the processing texture information transmitted from the digital mold.
7. The tile printing method based on code spraying identification as claimed in claim 3, wherein a ground coat is further applied on the tile body to form a ground coat layer before texture processing in step b, the identification code is applied on the ground coat layer of the tile, and the identification code is formed by spraying and painting with an organic solvent.
8. A tile printing method based on code-spraying identification according to any one of claims 1 to 7, wherein between step S1 and step S3, a glaze is applied to the tile blank, and the printing device prints a corresponding pattern on the glaze according to the information reflected by the identification code.
