Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glazing equipment, in particular to an easy-to-clean antibacterial ceramic tile glazing and enameling device. BACKGROUND

[0002] In the glazing process of ceramic tile production, the glazing method has become the core glazing method for various ceramic tiles such as exterior wall tiles, interior wall tiles and antique tiles due to its convenient operation and wide adaptability. The bell-type glazing device is the most widely used equipment in this process, but the existing technology and similar improvement schemes still have many deep-seated defects in actual application, which are difficult to meet the production needs of high efficiency, precision and low consumption.

[0003] Although the traditional bell-type glazing device is nominally suitable for multiple specifications of ceramic tiles, its glazing range is a fixed structure. When the size of the ceramic tile is switched from large to small, a fixed ineffective glazing area will be formed on the symmetrical sides of the bell. The glaze that does not contact the ceramic tile directly flows into the glazing box and needs to be pumped back to the glazing device for circulation, resulting in a glaze return consumption of more than 30%. Not only is this wasteful of resources, but it also causes viscosity fluctuations and particle agglomeration due to repeated circulation of the glaze, indirectly affecting the glazing quality. Even if some improved schemes such as CN209851216U adjust the circumferential angle of the adjusting baffle on the glazing disc, the adjusting method can only achieve rough control of the glazing width and cannot accurately match the glazing area according to the dynamic scenario of horizontal ceramic tile conveying. During the adjusting process, the baffle may deviate from the glaze flow direction, resulting in glaze overflow at the glazing boundary and internal glaze leakage. Moreover, the glaze restraining effect after adjusting the baffle is unstable and difficult to adapt to the rapid changeover requirements of continuous production lines.

[0004] Moreover, the uniformity of glaze distribution is a key indicator of ceramic tile quality. Traditional glazing equipment lacks optimal design of glaze flow patterns, and the glaze falls in a columnar or dispersed manner, which easily produces flow marks and local accumulation when it comes into contact with the surface of the ceramic tile, resulting in a glaze layer thickness difference on the surface of the ceramic tile that exceeds the standard limit and poor consistency in glossiness. At the same time, traditional schemes do not have effective glaze guiding structures. Glaze that flows out of the glazing device is prone to splashing, which not only contaminates the equipment but also forms irregular glaze edges on the edges of the ceramic tile, increasing the cost of the subsequent edge trimming process. Compared with non-ceramic tile field spraying equipment such as the rock panel spraying device of CN116872603A and the steel drum spraying device of CN207605901U, the viscosity and flowability of the glue, paint and other media targeted by such equipment are significantly different from those of ceramic tile glaze. The flat nozzle structure of such equipment can only improve the coverage uniformity of static spraying and lacks a dynamic adjustment mechanism suitable for horizontal continuous conveying of ceramic tiles, which cannot solve the problem of uniform spreading of glaze on continuously moving ceramic tiles, let alone glaze return consumption.

[0005] Therefore, the present application proposes a solution. Summary of the Invention

[0006] The purpose of this invention is to provide an easy-to-clean antibacterial ceramic tile glazing device to solve the problems mentioned above.

[0007] The objective of this invention can be achieved through the following technical solution: an easy-to-clean antibacterial ceramic tile glazing device, comprising a glaze receiving box and a glaze inlet assembly and a glaze guide assembly disposed on the glaze receiving box, wherein a transmission mechanism for horizontally transporting ceramic tile pieces is disposed above the glaze receiving box. The glaze inlet assembly includes a glaze inlet box suspended above the glaze receiving box, and a pair of glaze inlet boxes are symmetrically arranged and connected at the bottom with a glaze outlet flat nozzle. The glaze guiding assembly includes a bell-shaped plate fixedly installed above the transmission mechanism. The cross-section of the bell-shaped plate has a flat, smooth arc-shaped structure. A first glaze guide rail and a second glaze guide rail are rotatably mounted on the upper surface of the bell-shaped plate. The first glaze guide rail and the second glaze guide rail form a glazing area corresponding to the conveying direction of the transmission mechanism. The glazing area is converted by the cross-conversion action of the first glaze guide rail and the second glaze guide rail.

[0008] The glaze receiving box is further configured such that side support rods are installed on both sides, and a top frame is installed on the upper end of the side support rods. The bell-shaped plate is connected to the inner side of the side support rods.

[0009] The top frame is further configured such that a flexible support structure is installed in the middle, the flexible support structure includes a support frame and a spring, the lower end of the support frame is connected to a bottom ring through a locking rod, the spring is sleeved on the outside of the locking rod near the bottom ring, and the upper and lower ends of the spring are respectively connected to the locking rod and the bottom ring.

[0010] The bottom ring is further configured such that a glaze inlet pipe connected to the glaze inlet box is inserted in the middle of the bottom ring, a concentrator pipe is connected to the bottom of the glaze inlet box, and the lower end of the concentrator pipe is connected to the glaze outlet nozzle.

[0011] A further configuration is provided: a fixing cylinder is installed at an inward angle on the outer middle of the pair of glaze inlet boxes, and a rotating shaft is rotatably provided in the middle of the fixing cylinder, with the rotating shaft extending into the glaze inlet box to install a magnetic mesh.

[0012] Further configuration: a mounting box is provided at the bottom of the pair of glazing boxes, a motor is installed on one side of the inside of the mounting box, the output end of the motor is connected to a drive tooth, and the upper and lower ends of the drive tooth are engaged with a horizontally symmetrically arranged positive and negative helical teeth.

[0013] The design is further configured such that: an inner rotating rod is provided in the middle of the first glaze guide rail, and an outer rotating cylinder is provided in the middle of the second glaze guide rail that is rotatably connected to the inner rotating rod; the positive rotating tooth is provided at the top of the inner rotating rod, and the negative rotating tooth is provided on the outer side of the upper end of the outer rotating cylinder.

[0014] The glaze receiving box is further configured such that its bottom cross-section is tapered, and a glaze return pipe is installed at the bottom of the glaze receiving box. The glaze return pipe is connected to the glaze inlet pipe through a suction device.

[0015] The present invention has the following beneficial effects: This invention utilizes a structural design that combines two glazing guides (one with a length equal to the diameter of the bell-shaped plate) arranged in a crisscross pattern with a flat glazing nozzle to create a "double-sided glazing area." First, the flat glazing nozzle restricts the flow of glaze, creating a "flattened glazing distribution." Then, the "double-sided glazing area" formed by the glazing guides and the bell-shaped plate achieves continuous, bidirectional glazing. The combination of these two elements results in a continuous, uniform glazing distribution on both sides, achieving absolute control over the amount and area of ​​glaze applied. This allows for continuous glazing of continuously moving ceramic tiles under dual constraints on glaze quantity and area, making it suitable for glazing ceramic tiles of different sizes.

[0016] This invention also incorporates a rotatable magnetic mesh inside the glaze inlet to efficiently adsorb metallic impurities in the glaze liquid, completely avoiding defects such as black spots and scratches caused by impurities during glazing. This improves the continuity of the antibacterial glaze layer. In contrast, traditional equipment and all similar comparative documents do not have a targeted impurity removal structure, making it unable to cope with impurities that are mixed in during the transportation process. At the same time, the flexible support structure buffers the pressure fluctuations and equipment vibrations during glaze liquid injection with springs, resulting in high precision control of the coefficient of variation of the dripping rate. The glazing stability far exceeds that of traditional rigid fixed structures, further ensuring the uniformity and performance consistency of the glaze layer. Attached Figure Description

Detailed Implementation

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Existing tile glazing equipment and similar solutions cannot achieve precise dynamic adaptation of the glazing area according to the tile size, resulting in severe glaze consumption during rotation, blurred glazing boundaries, and uneven glaze distribution. This makes it difficult to meet the continuous production needs of multi-size tiles. Furthermore, there is a lack of targeted impurity removal structures during glaze delivery, and glazing stability is greatly affected by equipment vibration and pressure fluctuations. Maintenance of core components is inconvenient, leading to high product defect rates and limited production efficiency and equipment lifespan. The following technical solution is proposed: Reference Figure 1 - Figure 9 As shown, an easy-to-clean antibacterial ceramic tile glazing device in this embodiment includes a glaze receiving box 1 and a glaze inlet assembly and a glaze guide assembly disposed on the glaze receiving box 1. A transmission mechanism 5 for horizontally transporting ceramic tile pieces is disposed above the glaze receiving box 1. The glazing assembly includes a glazing box 9 suspended above the glazing box 1. A pair of glazing boxes 9 are symmetrically arranged and connected to the bottom with a glazing nozzle 10. For the glazing process of antibacterial tiles, the horizontal displacement of the tile is based on the transmission mechanism 5. The glaze is guided evenly on demand by the glaze guiding assembly to achieve uniform coverage. It can also prevent the problem of large glaze consumption caused by the size change of the tile and the mismatch between the original glazing range during the glazing process. Reference Figure 3 , Figure 4 and Figure 6 As shown, the glaze guiding assembly includes a bell-shaped plate 6 fixedly installed above the transmission mechanism 5. The cross-section of the bell-shaped plate 6 has a flat and smooth arc-shaped structure. The upper surface of the bell-shaped plate 6 is rotatably equipped with glaze guide rail 1 7 and glaze guide rail 2 15. The glaze guide rail 1 7 and glaze guide rail 2 15 form a glazing area corresponding to the conveying direction of the transmission mechanism 5. The glazing area is converted by the cross-conversion action of the glaze guide rail 1 7 and glaze guide rail 2 15. Based on the above description, the conversion of the glazing area is achieved through the cross conversion of glaze guide rail 1 7 and glaze guide rail 2 15. Specifically, the coaxial bidirectional rotation of glaze guide rail 1 7 and glaze guide rail 2 15 is completed respectively, which corresponds to the change of the glazing range of the ceramic tile in the transmission direction of the transmission mechanism 5. Further dripping of glaze liquid can complete the uniform glazing. Reference Figure 7 and Figure 8 As shown, a glazing pipe 8 connected to the glazing box 9 is inserted in the middle of the bottom ring 23. A concentrator pipe 11 is connected to the bottom of the glazing box 9. The lower end of the concentrator pipe 11 is connected to the glazing nozzle 10. As for the specific glazing process, the glaze is applied through the connection between the glazing pipe 8 and the glazing nozzle 10. Specifically, the glaze is drawn into the glaze inlet pipe 8 from the glaze storage device with a pre-set suction pump. After falling into a pair of glaze inlet boxes 9, it forms a uniform flow and is sprayed outward through the central pipe 11 and the glaze outlet flat nozzle 10 respectively. Due to the expansion of the glaze flow by the glaze outlet flat nozzle 10, the glaze is evenly distributed on the bell plate 6 and is limited by the area formed by the cross glaze guide rail 1 7 and glaze guide rail 2 15 on both sides. Finally, the glaze is evenly poured from the side of the bell plate 6 onto the ceramic tile piece that is continuously moving below. Regarding how to perform the transformation of the glaze distribution area, this invention adds the following: (Refer to...) Figure 4 and Figure 5 As shown, a mounting box 16 is provided at the bottom of a pair of glaze inlet boxes 9. A motor 22 is installed on one side inside the mounting box 16. The output end of the motor 22 is connected to a drive tooth 21. The upper and lower ends of the drive tooth 21 are meshed with a horizontally symmetrically arranged positive spiral tooth 19 and a negative spiral tooth 20. An inner rotating rod 18 is provided in the middle of the glaze guide rail 11. An outer rotating cylinder 17 that is rotatably connected to the inner rotating rod 18 is provided in the middle of the glaze guide rail 215. The positive spiral tooth 19 is located at the top of the inner rotating rod 18, and the negative spiral tooth 20 is located on the outer side of the upper end of the outer rotating cylinder 17. The specific transformation process is as follows: Motor 22 drives drive gear 21 to rotate in the forward direction. Drive gear 21 then drives forward gear 19 and reverse gear 20 to rotate in the same direction and in the opposite direction, respectively. Forward gear 19 drives inner rotating rod 18 and glaze guide rail 7 to rotate, while reverse gear 20 drives outer rotating cylinder 17 and glaze guide rail 15 to rotate. That is, the area of ​​the intersection of glaze guide rail 7 and glaze guide rail 15 in the direction of travel of the ceramic tile changes accordingly to ensure that it is adapted to the size of the ceramic tile traveling below.

[0022] The advantages of this invention are: Dynamic glazing area adaptive adjustment capability: Through the cross switching action of glaze guide rail 1 7 and glaze guide rail 2 15 (driven by motor 22 to drive drive gear 21, linking forward rotation gear 19 and reverse rotation gear 20, to realize the same and opposite rotation of inner rotating rod 18 and outer rotating cylinder 17), the area of ​​the glazing area is dynamically adjusted; so that the glazing range can adapt to the changes in the size of the tile in real time, such as when the width or length of the tile changes, to avoid uneven glazing or interruption caused by size mismatch. Specifically, the rotation of the glaze guide structure can precisely control the coverage width of the dripped glaze and the conveying direction of the transmission mechanism 5, ensuring that tiles of different specifications can achieve a consistent glazing effect, improving the flexibility and versatility of the production line, while reducing the need for manual intervention, reducing mold change downtime and improving equipment utilization (compared to the circumferential angle adjustment baffle of CN209851216U, it not only has a wider adjustment range, but can also match the dynamic scene of horizontal tile conveying in real time, avoiding edge overflow and internal glaze leakage problems, shortening mold change downtime and greatly improving the versatility of the production line; and the traditional bell-shaped glazing device cannot achieve dynamic adjustment of the glazing area, and the flat nozzle structure of non-tile spraying equipment lacks an adjustment mechanism adapted to continuous tile production, neither of which can meet the needs of efficient production of multi-specification tiles). Uniform glaze distribution and high-precision glazing function: Through the dynamic conversion of the glazing area (i.e., the cross action of glaze guide rail 1 7 and glaze guide rail 2 15), the problem of glaze return and consumption is effectively prevented. In traditional glazing, glaze that does not match the size flows back directly to the glaze receiving box 1, causing waste. The present invention, by defining the area of ​​the glaze guide rail 1 7 and the glaze guide rail 2 15, strictly confines the dripping glaze to the travel path of the ceramic tile, reducing splashing and backflow (compared to the structure of CN209851216U that does not optimize the glaze flow pattern, the resource saving effect is more significant, and the replacement cycle of the backflowing glaze is extended due to its low impurity content; although the spraying equipment in non-ceramic fields uses flat nozzles, the characteristics of the media they are used for are different, so they cannot achieve "two-way continuous application" of glaze, nor do they solve the problem of rotational consumption).

[0023] In summary, the "double-sided glazing area" is constructed by combining the glaze guide rails 1-7 and 2-15 (with a length equal to the diameter of the bell-shaped plate 6) with the glaze outlet flat nozzle 10. First, the glaze outlet flat nozzle 10 restricts the flow of glaze, creating a "flattened glazing" effect. Then, the "double-sided glazing area" formed by the glaze guide rails 1-7, 2-15, and bell-shaped plate 6 achieves continuous "bidirectional" glaze application. The combination of these two elements results in continuous and uniform glazing on both sides, achieving absolute control over the amount and area of ​​glaze. This allows for continuous glazing of the continuously moving ceramic tile under the dual constraints of glaze quantity and area, making it suitable for glazing ceramic tiles of different sizes.

[0024] Example 2: Refer to Figure 1 - Figure 9 As shown in Example 1, the following technical solution is proposed to ensure the stable delivery of the glaze liquid: The glaze receiving box 1 has side support rods 2 installed on both sides, and a top frame 3 is installed on the upper end of the side support rods 2. The bell plate 6 is connected to the inner side of the side support rods 2. A flexible support structure is installed in the middle of the top frame 3. The flexible support structure includes a support frame 4 and a spring 25. The lower end of the support frame 4 is connected to a bottom ring 23 through a locking rod 24. The spring 25 is sleeved on the outside of the locking rod 24 near the bottom ring 23. The upper and lower ends of the spring 25 are connected to the locking rod 24 and the bottom ring 23, respectively. By adopting a fixed installation structure for the bell-shaped plate 6 and a suspended installation structure for the glaze inlet assembly, stable glaze delivery is achieved. Specifically, a flexible support structure consisting of a support frame 4 and a spring 25 provides effective suspension support for the glaze inlet pipe 8 and the glaze inlet box 9. Furthermore, by monitoring the quality of the glaze inlet box 9 during the glaze delivery process, the tension of the spring 25 is adjusted to improve the stability of the glaze during the dripping process and ensure uniform glazing.

[0025] A fixed cylinder 12 is installed at an inward angle on the outer middle of a pair of glaze inlet boxes 9. A rotating shaft 13 is rotatably installed in the middle of the fixed cylinder 12. The rotating shaft 13 extends into the glaze inlet box 9 and a magnetic mesh 14 is installed there. During the glaze production process, iron powder and other metal impurities may be mixed in. In order to ensure that the ceramic tile pieces are fed without damage, an iron removal step must be performed, which specifically includes: A drive motor A is installed outside the rotating shaft 13. When the drive motor A starts, it drives the magnetic mesh 14 through the rotating shaft 13 to continuously adsorb iron-containing impurities in the glaze box 9. The diverted glaze liquid can fully contact the symmetrically arranged magnetic mesh 14 to ensure the removal of iron-containing impurities. For cleaning the magnetic mesh 14, the glaze box 9 is designed with a detachable transparent panel structure. If the magnetic mesh 14 is saturated, the transparent panel is removed to remove the magnetic mesh 14 and complete the cleaning. The bottom cross-section of the glaze receiving box 1 is conical. A glaze return pipe 26 is installed at the bottom of the glaze receiving box 1. The glaze return pipe 26 is connected to the glaze inlet pipe 8 through a suction device. Based on the unobstructed flow of glaze liquid, after glazing is completed, the unglazed glaze liquid is poured out of the ceramic tile and collected by the glaze receiving box 1. After being filtered and purified by the suction device, it continues to be glazed through the glaze inlet pipe 8, forming a glazing cycle. In addition, according to the method of reducing glaze liquid circulation consumption as described in Example 1, the glazing efficiency of the ceramic tile is improved.

[0026] Example 3: Refer to Figure 1 - Figure 9 As shown, this embodiment combines the technical content of Embodiment 1 and Embodiment 2 to constitute an easy-to-clean antibacterial ceramic tile glazing method, including the following steps: Glazing: The ceramic tile moves normally through the transmission mechanism 5. The glaze is drawn from the glazing inlet pipe 8 by the preset suction pump and then spreads into a thin layer through the expansion design of the glaze outlet flat nozzle 10, and drips onto the smooth arc surface of the bell plate 6. The moving speed of the ceramic tile is matched with the glazing rate. Impurity removal: During the glazing process, a drive motor A is installed outside the rotating shaft 13. When the drive motor A is started, it drives the magnetic mesh 14 through the rotating shaft 13 to continuously adsorb iron-containing impurities in the glazing box 9. The diverted glaze liquid can fully contact the symmetrically arranged magnetic mesh 14 to ensure the removal of iron-containing impurities. For cleaning the magnetic mesh 14, the glazing box 9 is designed with a detachable transparent panel structure. If the magnetic mesh 14 is saturated, the transparent panel is removed to remove the magnetic mesh 14 and complete the cleaning. Glazing area adjustment: According to the size of the tile, the motor 22 drives the cross rotation of the glazing guide rail 1 7 and the glazing guide rail 2 15 through the gear linkage system to complete the glazing area limitation, strictly constraining the dripping glaze on the travel path of the tile to form a uniform glaze. Circulating glaze: After glazing is completed, the glaze liquid is poured into the glaze receiving box 1, and then filtered and purified by the suction device before continuing to be glazed through the glaze inlet pipe 8, forming a glazing cycle.

[0027] In summary, the system achieves efficient and precise glazing of easy-to-clean antibacterial tiles through dynamic glazing area adjustment, uniform glaze distribution mechanism, high resource utilization, and automated integration. The core innovation lies in the synergistic effect of the glazing inlet component and the glaze guide component, which enables the adaptive adjustment of the dynamic glazing area and the uniform distribution and high-precision glazing of the glaze. This not only solves the size adaptation problem but also significantly reduces glaze consumption during rotation, thereby improving the glazing process efficiency of antibacterial tiles.

[0028] Specifically, the "double-sided glazing area" is formed by the cross-shaped glaze guide rails 7 and 15, which are the same length as the diameter of the bell-shaped plate 6, combined with the glaze outlet flat nozzle 10. First, the glaze outlet flat nozzle 10 restricts the flow of glaze, forming a "flattened glazing". Then, the "double-sided glazing area" formed by the glaze guide rails 7, 15 and 6 achieves "bidirectional" continuous application of glaze. The combination of the two forms a double-sided continuous and uniform application, which achieves absolute limitation on the amount and area of ​​glaze. That is, the continuously moving ceramic tile to be glazed can achieve double-sided continuous glazing operation under the dual limitation of glaze amount and glaze area during the glazing process, which is suitable for glazing ceramic tiles of different sizes.

[0029] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
