Description

Technical Field

[0001] This utility model relates to the field of ceramic tile glaze processing technology, and in particular to a flow guide bell jar and a glaze applicator for ceramic tile blanks having the same. Background Technology

[0002] In the process of tile manufacturing, the tile blank is usually made first, and then a glaze is applied to the surface of the tile blank. This creates a dried glaze on the surface of the tile blank, resulting in a sufficiently smooth and flat surface. The glazing of the tile surface is generally done by the glazing method. Specifically, a glazing device is used, with a bell jar to evenly pour the glaze onto the surface of the tile blank. The bell jar guides the flow to ensure that the thickness of the glaze curtain, the specific gravity of the glaze, and the viscosity of the glaze all meet the requirements and are evenly distributed.

[0003] Current technology commonly uses a circular arc-shaped bell-shaped cover structure. In practice, it has been found that when glazing is applied to the brick blank under the bell-shaped cover, the glaze poured onto the brick blank will produce bell-shaped streaks (arc-shaped stripes perpendicular to the direction of brick entry) due to the curved surface of the bell-shaped cover, affecting the glazing effect. Furthermore, the vibration generated by the bell-shaped cover during operation also creates bell-shaped streaks. Therefore, once the bell-shaped cover structure is fixed, it is not suitable for frequent disassembly and replacement to avoid affecting the stability of the glazing effect. This makes it difficult to solve the above problems simply by replacing the bell-shaped cover with a suitable one. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a flow guide bell jar and a glazing device for brick blanks having the same.

[0005] According to a first aspect of the present invention, a flow-guiding bell jar includes: a glazing bucket with a glaze delivery hole on its lower side; a glazing cover located below the glazing bucket, the glazing cover having a glaze guiding surface; and a straight glazing plate detachably connected to the front side of the glazing cover, the straight glazing plate including, from front to back, a transition section, a flat section, and an arc-shaped section, the rear side of the transition section being connected to the lower side of the glaze guiding surface of the cover, the rear end of the flat section being connected to the outer edge of the front end of the transition section, and the arc-shaped section having a convex arc surface facing the upper front side.

[0006] According to some embodiments of the present invention, a flow stabilizing ring is provided at the middle position on the upper side of the glazing cover, the flow stabilizing ring has a flow stabilizing cavity, and a flow stabilizing ring glaze outlet slit is provided on the front side wall of the flow stabilizing ring.

[0012] The flow-guiding bell jar according to the embodiment of this utility model has at least the following technical effects: 1. The glaze on the glaze cover is guided by the straight glaze plate. After flowing through the convex surface of the arc part, the glaze flows downward at the front end of the arc part to form a straight glaze curtain of uniform thickness.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] The following is for reference. Figure 1 and Figure 2 Description of a flow-guiding bell jar according to an embodiment of the present invention.

[0025] like Figure 1 and Figure 2 As shown, the flow guide bell jar according to an embodiment of the present utility model includes a glazing bucket 100, a glazing cover 200, and a straight glazing plate 300.

[0026] The glazing bucket 100 has a glaze delivery hole 121 on its lower side; the glazing cover 200 is located below the glazing bucket 100 and has a glaze guiding surface 210; the straight glazing plate 300 is detachably connected to the front side of the glazing cover 200. The straight glazing plate 300 includes, from front to back, a transition surface 310, a flat part 320 and an arc-shaped part 330. The rear side of the transition surface 310 is connected to the lower side of the glaze guiding surface 210, the rear end of the flat part 320 is connected to the outer edge of the front end of the transition surface 310, and the arc-shaped part 330 has a convex arc surface 331 facing the upper front side.

[0027] For example, such as Figure 1 and Figure 2 As shown, the glazing bucket 100 has a glaze delivery hole 121 on its lower side, which can deliver glaze slurry downwards. The glazing bucket 100 remains relatively stationary during operation. The glazing cover 200 is located below the glazing bucket 100, so that the glazing cover 200 can catch the glaze slurry delivered by the glazing bucket 100. The glazing cover 200 has a glaze guiding surface 210, which allows the glaze slurry on the glazing cover 200 to spread along the surface of the glaze guiding surface 210 to the surrounding area of ​​the glazing cover 200. A straight glazing plate 300 is detachably connected to the front of the glazing cover 200. The straight glazing plate 300 is fixedly connected to the glazing cover 200 and can be disassembled and replaced. The straight glaze plate 300 includes, from front to back, a transition surface 310, a flat section 320 and an arc-shaped section 330. The rear side of the transition surface 310 is connected to the lower side of the glaze guide surface 210 of the cover. The rear end of the flat section 320 is connected to the outer edge of the front end of the transition surface 310. The arc-shaped section 330 has a convex arc surface 331 facing the upper front side.

[0028] In practical work, refer to Figure 4 The glazing hopper 100 serves as a glaze slurry release container, discharging glaze slurry that is evenly spread on the surface of the brick blank 500 to be processed.

[0029] The glaze guide surface 210 of the cover is located below the glaze pouring tank 100. The glaze slurry output from the glaze pouring tank 100 flows to the surface of the glaze guide surface 210 and flows along the spherical crown surface of its surface, spreading to the periphery of the glaze pouring cover 200.

[0030] Because the glaze guiding surface 210 of the cover body and the transition surface 310 of the straight glaze-spraying plate 300 are smoothly connected, the glaze slurry passing through the glaze guiding surface 210 of the cover body can flow smoothly through the transition surface 310 of the straight glaze-spraying plate 300 to the flat section 320 and spread out. The flat section 320, as the transition structure between the transition surface 310 and the curved section 330, ensures that the glaze slurry on the flat section 320 can flow to the position of the curved section 330 at a relatively uniform speed and stably. Then, after flowing through the convex arc surface 331 of the curved section 330, the glaze slurry flows downward at the front end of the curved section 330 to form a straight glaze curtain of uniform thickness.

[0031] By utilizing the spherical cap surface of the glaze guide surface 210 and the arc surface of the convex arc surface 331, the glaze slurry is thinned and homogenized under the action of the liquid surface tension formed by the viscosity of the glaze slurry itself, which can effectively eliminate fine air bubbles in the glaze slurry.

[0032] The convex arc surface 331 of the arc section 330 allows the glaze slurry to be output through the front end of the arc section 330, ensuring that the output of the thinned and homogenized glaze slurry forms a stable straight glaze curtain.

[0033] As the brick blank 500 passes through the aforementioned glaze curtain from back to front, the glaze slurry will be evenly spread on the surface of the brick blank 500, forming a glaze film of uniform thickness, thus completing the glazing process. The straight glaze curtain of uniform thickness that flows downward from the front end of the arc-shaped part 330 ensures that the glaze slurry spread on the surface of the brick blank 500 will not form bell-shaped patterns.

[0034] During the above process, neither the glazing cover 200 nor the straight glazing plate 300 needs to be moved. The straight glazing plate 300 can be flexibly replaced according to the size of the tile blank 500. In particular, a larger straight glazing plate 300 can be installed on the basis of the original smaller glazing cover 200 to cooperate in the production of larger sized tile blanks 500. For example, the existing technology originally required a 1800 specification glazing cover 200 to produce 800×800 specification tiles. After adding a suitable straight glazing plate 300, a 1500 specification glazing cover 200 can be used in conjunction with the straight glazing plate 300 to produce 800×800 specification tiles.

[0035] This allows for the replacement of only the straight glazing plate 300 to match different sized brick blanks 500, without the need to completely disassemble the glazing cover 200, thus avoiding loosening caused by frequent disassembly of the glazing cover 200. Furthermore, the straight glazing plate 300 is a relatively lightweight component, making it easy to ensure its secure fixing. This is sufficient to guarantee that the flow guide bell jar of this invention will not develop bell-shaped patterns due to vibration during operation.

[0036] It is conceivable that the brick blank 500 mentioned above could refer to ceramic tiles, slabs, or other blanks or products that require glazing, but is not limited to ceramic tiles, slabs, and daily-use ceramics.

[0037] In some embodiments of this utility model, reference is made to Figure 3 , Figure 5 A flow-stabilizing ring 220 is positioned at the center of the upper side of the glazing cover 200. The flow-stabilizing ring 220 has a flow-stabilizing cavity 221, and a glaze outlet slit 222 is formed on the front wall of the flow-stabilizing ring 220. The glaze slurry flows slowly and settles within the flow-stabilizing cavity 221, preventing the formation of minor ripples. Once a sufficient amount of glaze has accumulated within the flow-stabilizing cavity 221, it overflows forward through the glaze outlet 222 and flows to the glaze guide surface 210 of the cover. This ensures a sufficiently uniform glazing effect.

[0038] In some embodiments of this utility model, reference is made to Figure 7 , Figure 8 The flow stabilizing ring 220 includes a lower flow stabilizing frustum 223. The glaze outlet 222 of the flow stabilizing ring is located on the upper side of the flow stabilizing frustum 223. The outer wall of the flow stabilizing frustum 223 has a frustum inclined surface 224. The flow stabilizing frustum 223 has a vertical axis, and the frustum inclined surface 224 is inclined along the direction from the upper side close to the vertical axis to the lower side away from the vertical axis. The flow stabilizing structure formed above can ensure that the flow stabilizing cavity 221 has enough space for the glaze to settle, and the frustum-shaped design of the flow stabilizing frustum 223 can also eliminate surges, which is sufficient to ensure that the glazing effect is sufficiently uniform.

[0039] In some embodiments of this utility model, a glaze receiving cylinder 230 is provided inside the flow stabilizing cavity 221. The glaze receiving cylinder 230 has a glaze receiving cylinder cavity 231 and an upper opening 232, and the glaze delivery hole 121 is located above the upper opening 232. The glaze slurry output from the glaze pouring bucket 100 enters the glaze receiving cylinder cavity 231 of the glaze receiving cylinder 230, which can reduce bubbles caused by glaze slurry splashing.

[0040] In some embodiments of this utility model, a defoaming cylinder 240 is provided inside the cavity 231 of the receiving glaze cylinder. The defoaming cylinder 240 has a cavity 241 and an upper opening 242. The horizontal position of the upper opening 232 of the receiving glaze cylinder is lower than the horizontal position of the upper opening 242 of the defoaming cylinder. A defoaming mesh 243 is connected to the wall of the upper opening 242 of the defoaming cylinder. In this way, the glaze slurry output from the glazing tank 100 first flows into the cavity 241 of the defoaming cylinder through the upper opening 242 of the defoaming cylinder. When the defoaming cylinder 240 is full of glaze slurry, it overflows from the upper opening 242 of the defoaming cylinder. After the defoaming mesh 243 removes air bubbles, it flows into the cavity 231 of the receiving glaze cylinder 230, further ensuring that the glaze slurry is free of air bubbles.

[0041] In some embodiments of this utility model, reference is made to Figure 6A glazing cover support ring 250 is provided on the lower side of the glazing cover 200, and a fixing member 251 is provided on the lower side of the glazing cover support ring 250. The glazing cover support ring 250 is connected to the transition surface 310 through the fixing member 251. The glazing cover support ring 250 ensures that the glazing cover 200 has sufficient structural support to guarantee the stability of the glazing cover 200 during the flow guiding process. The straight glazing plate 300 can be fixed to the glazing cover support ring 250 by the fixing member 251. This facilitates the assembly and disassembly of the straight glazing plate 300.

[0042] In some specific embodiments of this utility model, the fixing member 251 is a screw.

[0043] In some specific embodiments of this utility model, the fixing member 251 is a ring structure, and the glaze cover support ring 250 is connected to the fixing member 251 by screws.

[0044] In some embodiments of this utility model, reference is made to Figure 9 The glaze guiding surface 210 of the glaze cover can guide the glaze slurry forward to the position of the straight glaze-spraying plate 300. Under the premise of achieving the above-mentioned technical effect, various specific embodiments of the glaze guiding surface 210 of the glaze cover are all within the scope of protection. For example, the glaze guiding surface 210 on the glaze-spraying cover 200 can adopt a curved surface structure such as a spherical cap surface or an arc surface, or a flat inclined surface structure. The aforementioned curved surface structure is preferably a regular curved surface.

[0045] Furthermore, a sealing strip is provided at the rear side of the glaze guiding surface 210 of the cover, so that the glaze slurry can be blocked from flowing to the rear side of the glaze guiding surface 210. The sealing strip can be made of rubber strips, cloth strips, etc.

[0046] Furthermore, the glaze guiding surface 210 of the cover adopts a spherical crown structure, that is, the glaze guiding surface 210 of the cover is a convex spherical crown surface that is high in the middle and low around the edges. Such glaze can flow along the surface of the spherical crown structure to the straight glaze plate 300.

[0047] Furthermore, the glaze guiding surface 210 of the cover adopts an arc structure, that is, the glaze guiding surface 210 of the cover is a convex arc surface with a high rear side and a low front side, so that the glaze on the glaze guiding surface 210 of the cover can flow along the surface of the arc structure to the straight glaze plate 300.

[0048] Furthermore, the glaze guiding surface 210 of the cover adopts a flat inclined surface structure, that is, the glaze guiding surface 210 of the cover is an inclined surface that slopes from the upper rear side to the lower front side, so that the glaze on the glaze guiding surface 210 of the cover can flow along the surface of the flat inclined surface structure to the straight glaze plate 300.

[0049] In addition, the glaze guide surface 210 of the cover can also adopt a conical or frustum-shaped structure.

[0050] In some embodiments of this utility model, reference is made to Figure 10The rear end of the convex arc surface 331 is connected to the front end of the flat section 320, and the front end of the convex arc surface 331 points downward. In this way, after the glaze flows through the arc section 330 and along the convex arc surface 331, it ensures that the straight glaze curtain formed by the glaze flowing downward through the front end of the arc section 330 is sufficiently uniform and stable.

[0051] In some specific embodiments of this utility model, the glaze guiding surface 210 of the glaze cover 200 and the transition surface 310, flat part 320, and arc-shaped part 330 of the straight glaze plate 300 are required to have smooth and even surfaces, and must not have any local unevenness or wavy texture. The end of the straight arc-shaped part 330 must be straight and smooth, and must not have any bends, local protrusions, or gaps.

[0052] In some specific embodiments of this utility model, the transition surface 310, flat part 320 and arc-shaped part 330 of the straight glazed plate 300 are smoothly connected. The straight glazed plate 300 preferably adopts an integral structure. For components such as the straight glazed plate 300 with different shapes, different processes can be used for manufacturing, such as mold opening and bending processes.

[0053] The brick blank glazing device according to a second aspect of the present invention includes a flow guide bell jar according to the first aspect of the present invention. That is, the flow guide bell jar is used for glazing brick blanks 500. The brick blank 500 can be various blanks or products requiring glazing, including but not limited to ceramic tiles, slabs, and everyday ceramics.

[0054] According to the brick glazing device of this utility model embodiment, by adopting the above-mentioned flow guide bell jar, the bell jar pattern formed during the glazing process is reduced, thereby optimizing the glazing effect. Moreover, the straight glazing plate 300 can be replaced as needed to improve the flexibility of the work.

A support bridge 421 is provided on the glaze cover fixing frame 420, and the support bridge 421 is connected to the lower side of the glaze cover 200. The glaze bucket 100 is fixed by the glaze bucket fixing frame 410, and the glaze cover 200 is fixed by the glaze cover fixing frame 420, ensuring that the glaze bucket 100 and the glaze cover 200 are sufficiently stable during operation.

[0056] In some embodiments of this utility model, a glaze slurry pipe 110 is externally connected to the upper side of the glaze-sprinkling tank 100, and a glaze slurry source is externally connected to the glaze slurry pipe 110. A feeding nozzle 120 is provided on the lower side of the glaze-sprinkling tank 100, and a glaze delivery hole 121 is opened in the feeding nozzle 120. A ball valve 122 is provided on the feeding nozzle 120. The glaze slurry pipe 110 can continuously feed glaze slurry into the glaze-sprinkling tank 100. After the ball valve 122 is opened, the glaze slurry can be output through the glaze delivery hole 121 of the feeding nozzle 120. This allows for convenient control of the opening and closing of the glaze-sprinkling tank 100.
