Description

Technical Field

[0001] This utility model relates to the field of ceramic tile glazing technology, and in particular to a device for applying glaze to the bottom of a ceramic tile. Background Technology

[0002] The glazing method refers to the glazing method of using a glazing sprayer to atomize and spray glaze onto the surface of the ceramic tile body. This method can spray a thin and uniform glaze layer onto the surface of the body and is mainly suitable for large and complex ceramic products.

[0003] When it is necessary to apply a base glaze to the bottom of a tile blank, the existing spraying method usually involves placing the bottom of the tile blank facing upwards and then spraying the glaze onto the bottom surface of the tile blank through a spray nozzle above. Although this spraying method can evenly cover the tile blank with glaze, when the surface or bottom of the tile has uneven patterns or designs, due to the fluidity of the glaze, it will automatically flow towards the concave surface under the action of gravity. This will result in uneven thickness of the glaze on the tile, affecting the subsequent firing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a glazing device for the base glaze of brick blanks, which aims to solve the problem of uneven glaze thickness when the existing glazing device sprays curved ceramic tiles.

[0005] To achieve the above objectives, this utility model provides a glazing device for the base glaze of a brick blank, including a lower glazing cabinet, on which multiple sets of spray gun assemblies and a transmission assembly are arranged, with the transmission assembly positioned above the multiple sets of spray gun assemblies.

[0031] The present invention will be described in detail below with reference to specific embodiments.

[0032] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0033] like Figures 1 to 9 As shown, this utility model provides a glazing device for the bottom glaze of a brick blank, including a lower glazing cabinet 1, on which multiple sets of spray gun assemblies 2 and a transmission assembly 3 are arranged, with the transmission assembly 3 arranged above the multiple sets of spray gun assemblies 2.

[0034] The transmission assembly 3 includes a brick-moving motor 30, a linkage gear set 31, linkage rods 32, and hot fin rods 33. The linkage gear set 31 is mounted on the lower glazing cabinet 1. Multiple sets of linkage rods 32 are evenly mounted on the linkage gear set 31. Each set of linkage rods 32 is equipped with a hot fin rod 33. Multiple sets of hot fins 34 are evenly arranged on the hot fin rods 33. The brick-moving motor 30 is mounted on the linkage gear set 31. The brick-moving motor 30 drives the multiple sets of linkage rods 32 to rotate through the linkage gear set 31.

[0035] Through the above design scheme, the brick feeding method using a rod drive effectively reduces the contact area between the brick blank and the transmission component 3 during movement by using the hot fins 34 on the hot fin rod 33. This reduces the impact on the glaze surface caused by the transmission structure adhering to and carrying away glaze. The brick feeding motor 30 drives multiple sets of linkage rods 32 to rotate together through the gears in the linkage gear set 31. The rotating linkage rods 32 drive the brick blank to pass over the lower glazing cabinet 1 through the hot fins 34 on the hot fin rod 33.

[0036] In this embodiment, each spray gun assembly 2 includes an air pipe 20, a three-way adapter 21, and a gun barrel 22. The lower glazing cabinet 1 is provided with multiple air pipes 20, each air pipe 20 is equipped with multiple three-way adapters 21, and each three-way adapter 21 is equipped with a gun barrel 22. The lower glazing cabinet 1 is provided with multiple sets of side fixing members 25, each side fixing member 25 is equipped with a fixing pipe 26, and each fixing pipe 26 is equipped with multiple sets of brackets 27. The brackets 27 are used to fix the gun barrel 22 and adjust the tilt angle of the gun barrel 22. The angle between the central axis of the gun barrel 22 and the vertical direction is 0° to 5°.

[0037] With the above design, when the tiles enter the lower glazing chamber 1, the external glazing pump device pumps the glaze from the hopper and then delivers it to each gun barrel 22 through the air pipe 20. The glaze is then sprayed upwards through the nozzle at the end of the gun barrel 22, applying a layer of glaze to the bottom of the tile. The fixing pipe 26 provides a support point for the gun barrel 22, preventing it from tilting during glazing under the action of reaction force. The operator adjusts the tilt angle of the gun barrel 22 as needed to prevent backflowing glaze from interfering with the glaze sprayed from the gun barrel 22 and affecting the uniformity of the glaze on the tile.

[0038] In this embodiment, an electromagnetic ball valve 23 is provided between the gun barrel 22 and the three-way adapter 21, and a protective cover 24 is provided above the electromagnetic ball valve 23. The protective cover 24 is installed on the gun barrel 22. A detection sensor is provided on the lower glaze cabinet 1, and the detection sensor is electrically connected to the electromagnetic ball valve 23.

[0039] Through the above design scheme, the electromagnetic ball valve 23 can automatically control the opening and closing of the gun barrel 22. When the detection sensor detects that the brick blank has come above the gun barrel 22 on the same group of air pipes 20, the electromagnetic ball valve 23 will start automatically after receiving the signal, spraying the glaze onto the bottom surface of the brick blank. When the detection sensor detects that the brick blank has left the gun barrel 22 on the same group of air pipes 20, the electromagnetic ball valve 23 will close automatically after receiving the signal, reducing the waste of glaze.

[0040] In this embodiment, a passive end cover 36 is provided on the side of the lower glaze cabinet 1 away from the linkage gear set 31; the passive end cover 36 is used to protect the linkage rod 32 and prevent the extended linkage rod 32 from being interfered with.

[0041] In this embodiment, a return cover 35 is provided in the lower glazing cabinet 1. The return cover 35 is located directly below the hot fin rod 33 and between the two sets of spray gun assemblies 2. The return cover 35 is used to guide excess glaze back into the lower glazing cabinet 1, reducing the impact of excess glaze on the spraying effect of the spray gun assembly 2.

[0042] In this embodiment, an upper glazing cabinet 4 is provided above the lower glazing cabinet 1. The upper glazing cabinet 4 is provided with an inlet / outlet 40 and an exhaust vent 42. The position where the tile enters the lower glazing cabinet 1 is defined as the front end. The front and rear ends of the upper glazing cabinet 4 are equipped with inlets / outlets 40. The side wall of the upper glazing cabinet 4 is provided with a ventilation opening 43, which is connected to the exhaust vent 42.

[0043] Through the above design scheme, the glazing cabinet 4 can prevent the glaze from drifting into the factory. The inlet and outlet 40 on the glazing cabinet 4 is used for the brick blanks to enter and exit the lower glazing cabinet 1. The exhaust port 42 on the glazing cabinet 4 is used to connect to the ventilation channel or filter device of the factory. With the help of the suction provided by the external equipment, the glaze is extracted through the ventilation port 43, so as to avoid the excess glaze from polluting the air in the factory.

[0044] In this embodiment, a side door 41 is provided on the side of the glazing cabinet 4. The side door 41 is hinged to the glazing cabinet 4 and is equipped with a door lock and a handle.

[0045] In this embodiment, glaze cabinet doors 11 are hinged to both the left and right sides of the lower glaze cabinet 1.

[0046] With the above design scheme, the side door 41 and the glazed cabinet door 11 can facilitate staff to explore the internal condition and make it convenient to observe or repair.

[0047] In this embodiment, a reflux section 10 is provided at the bottom of the lower glaze cabinet 1. The reflux section 10 is inclined, and a discharge pipe is provided at the bottom of the reflux section 10. The reflux section 10 guides the refluxed glaze to the discharge pipe, which is connected to a pumping device or a recycling box to pump excess glaze back to the spray gun assembly 2 or collect it.

[0048] With the above design scheme, when it is necessary to glaze the curved brick blank, the material pump applies a pressure of 3-10 bar to the glaze, so that it is sprayed out from the bottom of the gun barrel 22 through the nozzle; the nozzle on the gun barrel 22 can rotate freely to adjust the shape of the sprayed glaze. Since the relevant design of the nozzle is existing technology, it is not described in detail in this embodiment.

[0049] By adjusting the nozzle, the glaze sprayed from the gun barrel 22 will be atomized into blade-shaped or fan-shaped glaze slurry, reducing the amount of glaze used. Then, by adjusting the positions of the side fixing piece 25 and the fixing tube 26, the glaze slurry is made to just cover the bottom of the brick blank. Since the glaze is sprayed from bottom to top, if the glaze adhering to the brick blank is too thick, the excess glaze will drip into the return section 10 under gravity. Because the glaze surface needs to be turned upwards during subsequent firing, the glaze that can still flow slightly will be re-spread, ensuring a more uniform glaze thickness on the brick blank and preventing all the glaze on the uneven curved surface from flowing into the recessed areas. At the same time, the necessary rather than excessive glaze adhesion reduces the absorption of water from the glaze slurry by the brick blank, reducing subsequent drying time and energy consumption.

[0050] Because the contact area between the hot fins 34 and the ceramic tile is small, even if the tile comes into contact with the area coated with glaze during the transmission process, the glaze will flow on its own to fill the area that the hot fins 34 have passed through when the tile leaves the area of ​​the hot fins 34, reducing interference with the tile.

[0051] The glazing device for brick blanks provided by this utility model, compared with the prior art, when the brick blank enters the glazing device, the detection sensor detects the passing of the tile, and the electromagnetic ball valve 23 that receives the signal is activated to spray the glaze from bottom to top. Under the action of gravity, the excess glaze will drip into the return section 10 instead of accumulating in the recessed area of ​​the brick blank, ensuring a more uniform distribution of the glaze.

[0052] Where there is no conflict, the above embodiments and features can be combined with each other.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
