Abstract
Description
Technical Field
[0001] This utility model relates to the field of building material production equipment technology, and in particular to a glazing device. Background Technology
[0002] In the production and processing of ceramic tiles, glazing is generally required. Compared to bell-shaped glazing machines, straight-line glazing machines apply glaze more evenly. However, existing straight-line glazing machines typically use a glaze-carrying roller to adhere glaze to the glaze pool, and then rotate to the glazing plate where the glaze on the roller is scraped off. This method is limited by the maximum adhesion capacity of the glaze-carrying roller, resulting in a relatively small glaze load. Furthermore, when the glaze-carrying roller increases its rotation speed to increase the glaze load, glaze pushing occurs, meaning the rate at which the glaze is fed off by the roller exceeds the rate at which it falls onto the glazing plate. This causes wavy streaks in the glaze, negatively impacting the glazing effect. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a glazing device with a simple structure, uniform glazing, and a high upper limit for the glazing rate.
[0004] To solve the above-mentioned technical problems, this utility model provides a glazing device, including a glazing component, a glaze storage tank, and a glaze supply component connected to the glaze storage tank, wherein the glaze slurry flows into the glaze storage tank through the glaze supply component.
[0005] The glaze storage tank is provided with an overflow port that connects with the glazing component. The bottom edge of the overflow port is an overflow edge, and the glazing component is provided with a glaze-spraying surface that is parallel to the overflow edge.
[0006] The glaze slurry in the glaze storage tank flows into the glazing surface from the overflow side.
[0007] As an improvement to the above solution, the space inside the glaze storage tank is divided into a flow stabilization space and a glaze inlet space. The flow stabilization space is located above the glaze inlet space, and a preset distance is left between the flow stabilization space and the glaze inlet space to form a transition space.
[0008] The glazing component is located in the glazing inlet space, and the overflow outlet is located in the flow stabilization space.
[0009] As an improvement to the above solution, the glaze supply component includes a glaze supply pipe located within the glaze storage tank and a glaze conveying pipe for connecting to the glaze supply equipment.
[0010] The glaze supply pipe has multiple glaze outlet holes. The glaze slurry of the glaze supply equipment flows sequentially through the glaze conveying pipe and the glaze supply pipe, and flows into the glaze storage tank from the glaze outlet holes.
[0011] As an improvement to the above solution, the glaze supply component further includes a drive shaft driven by rotation, the glaze supply pipe and the drive shaft are respectively located at both ends of the glaze supply pipe, and the two sides of the glaze storage tank are respectively provided with shaft mounting holes for installing the glaze supply pipe and the drive shaft.
[0012] As an improvement to the above solution, the surface of the glaze supply tube is circumferentially distributed with multiple stirring sections, and the glaze outlet is located between adjacent stirring sections.
[0013] As an improvement to the above solution, the glaze supply component further includes a filter screen. The filter screen is provided on the inner wall of the glaze supply tube, and the filter screen covers the glaze outlet hole. The glaze slurry in the glaze supply tube is filtered by the filter screen and flows out from the glaze outlet hole.
[0014] As an improvement to the above solution, the glaze supply component also includes a filter screen, which is disposed inside the glaze storage tank and separates the glaze storage tank vertically.
[0015] The glaze supply pipe is located below the filter screen. The glaze slurry in the glaze supply pipe flows out from the glaze outlet hole, is filtered by the filter screen, and flows to the overflow port.
[0016] As an improvement to the above solution, the glazing component includes a glazing plate and a structure for connecting with other components. The top surface of the glazing plate is the glazing surface, and the structure is located on the bottom surface of the glazing plate.
[0017] As an improvement to the above solution, the two sides of the glazed plate are respectively the glazing edge and the glazing edge. After the glaze overflows from the overflow edge, it flows into the glazed surface and finally flows out from the glazing edge.
[0018] The glaze storage tank is provided with a positioning surface corresponding to the glaze receiving edge. The positioning surface is arranged parallel to the overflow edge, and the glaze pouring edge abuts against the positioning surface, so that the glaze pouring surface and the overflow edge are arranged parallel to each other.
[0019] As an improvement to the above scheme, the surface of the overflow edge is an arc-shaped surface or an inclined surface, so that the top of the overflow edge is a straight line.
[0020] As an improvement to the above solution, the two side plates of the glaze storage tank are extended by a predetermined length to form a glazing mounting plate for installing the glazing component, and the two sides of the structure are provided with connecting holes for connecting the glazing mounting plate.

[0029] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0030] See Figure 1 and Figure 2 This utility model provides a glazing device, including: a glazing component 1, a glaze storage tank 2, and a glaze supply component communicating with the glaze storage tank 2, wherein the glaze slurry flows into the glaze storage tank 2 through the glaze supply component;
[0031] The glaze storage tank 2 is provided with an overflow port that connects with the glazing component 1. The bottom edge of the overflow port is an overflow edge 21. The glazing component 1 is provided with a glazing surface 1a that is parallel to the overflow edge 21.
[0032] The glaze slurry in the glaze storage tank 2 flows into the glazing surface 1a from the overflow edge 21.
[0033] Specifically, the space inside the glaze storage tank 2 is divided into a flow stabilizing space 2a and a glaze inlet space 2c. The flow stabilizing space 2a is located above the glaze inlet space 2c. A preset distance is left between the flow stabilizing space 2a and the glaze inlet space 2c to form a transition space 2b.
[0034] The glazing component 1 is located in the glazing inlet space 2c, and the overflow outlet is located in the flow stabilization space 2a. Therefore, by controlling the size range of the transition space 2b, the fluctuations caused by the glaze entering the glazing inlet space 2c can be buffered by the transition space 2b, thereby ensuring that the glaze on the top surface of the flow stabilization space 2a maintains a planar and stable flow state. This ensures that the overflowing glaze can flow evenly and smoothly into the glazing surface 1a.
[0035] The glaze supply component includes a glaze supply pipe 3 located within the glaze storage tank 2 and a glaze conveying pipe 4 for connecting to the glaze supply equipment. The glaze supply pipe 3 has multiple glaze outlet holes 31. The glaze slurry from the glaze supply equipment flows sequentially through the glaze conveying pipe 4 and the glaze supply pipe 3, and flows into the glaze storage tank 2 from the glaze outlet holes 31. Preferably, the surface of the glaze supply pipe 3 has multiple glaze outlet holes 31 axially formed. By releasing the glaze slurry through multiple holes, the fluctuations caused by the glaze slurry entering the glaze storage tank 2 are greatly reduced.
[0036] Furthermore, to reduce the problem of glaze slurry sedimentation in the glaze storage tank 2, the glaze supply component also includes a drive shaft 5 driven by rotation. The glaze delivery pipe 4 and the drive shaft 5 are respectively located at both ends of the glaze supply pipe 3. Rotary shaft mounting holes 22 for mounting the glaze delivery pipe 4 and the drive shaft 5 are provided on both sides of the glaze storage tank 2, meaning the glaze delivery pipe 4 can also function as a rotating shaft. Correspondingly, the rotating shaft mounting holes 22 are equipped with bearings for mounting the glaze delivery pipe 4 and the glaze supply pipe 3. Multiple stirring sections 32 are circumferentially distributed on the surface of the glaze supply pipe 3, and the glaze outlet 31 is located between adjacent stirring sections 32. Therefore, when an external drive device drives the drive shaft 5 to rotate, the stirring sections 32 can stir the glaze inlet space 2c, which is prone to glaze slurry sedimentation, thereby alleviating the problem of glaze slurry sedimentation. Preferably, the stirring section 32 can be a spiral blade, a hemispherical protrusion, or a columnar body with a fan-shaped, polygonal, or semi-circular cross-section.
[0037] Preferably, the horizontal cross-sectional area of the glaze storage tank 2 gradually increases from bottom to top, that is, the vertical cross-section of the glaze storage tank 2 is V-shaped. This arrangement increases the space occupied by the glaze supply pipe 3 in the glaze inlet space 2c, thereby increasing the stirring effect of the stirring unit 32 on the glaze inlet space 2c. In this case, while ensuring the stirring effect, the rotational speed of the glaze supply pipe 3 can be reduced, thus reducing the glaze slurry fluctuation problem caused by the high-speed stirring of the stirring unit 32. Preferably, the bottom of the glaze storage tank is provided with a glaze discharge hole for draining the glaze slurry.
[0038] To improve the quality of the glaze slurry during glazing, the glaze supply component also includes a filter screen 6. The filter screen 6 is provided on the inner wall of the glaze supply pipe 3, and covers the glaze outlet 31. The glaze slurry in the glaze supply pipe 3 is filtered by the filter screen 6 and flows out from the glaze outlet 31. The filter screen 6 not only filters out a finer glaze slurry, preventing accidental particulate impurities from entering the glazing plate, but also greatly buffers the impact of the glaze slurry entering the glaze inlet space 2c, thereby further ensuring the stability of the glaze slurry in the stable flow space 2a.
[0039] Regarding the filter setup, this utility model also provides another implementation method, see [link to relevant documentation]. Figure 3 The glaze supply component further includes a filter screen 6, which is disposed within the glaze storage tank 2, dividing the tank vertically. The glaze supply pipe 3 is located below the filter screen 6, and the glaze slurry in the glaze supply pipe 3 flows out from the glaze outlet 31, is filtered by the filter screen 6, and flows to the overflow port. Preferably, the inner wall of the glaze storage tank 2 is provided with support edges 25 on both sides for supporting the filter screen.
[0040] See Figure 2 The glazing component 1 includes a glazing plate 11 and a structure 12 for connecting with other components. The top surface of the glazing plate 11 is the glazing surface 1a, and the structure 12 is located on the bottom surface of the glazing plate 11. Preferably, the glazing surface 1a is an arc-shaped surface. The two sides of the glazing plate 11 are the glazing receiving edge 11a and the glazing edge 11b, respectively. After overflowing from the overflow edge 21, the glaze flows into the glazing surface 1a and finally flows out from the glazing edge 11b. Accordingly, during assembly, to ensure that the glazing surface 1a and the overflow edge 21 are arranged parallel to each other and to ensure the uniformity of glazing, the glaze storage tank 2 is provided with a positioning surface 2d corresponding to the glazing receiving edge 11a. The positioning surface 2d is arranged parallel to the overflow edge 21, and the glazing edge 11b abuts against the positioning surface 2d, so that the glazing surface 1a and the overflow edge 21 are arranged parallel to each other. Preferably, the surface of the overflow edge 21 is an arc-shaped surface or an inclined surface, so that the top of the overflow edge 21 is a straight line.
[0041] The two side plates of the glaze storage tank 2 extend by a predetermined length to form a glazing mounting plate 23 for mounting the glazing component 1. The two sides of the structure 12 are provided with connecting holes 121 for connecting the glazing mounting plate 23.
[0042] The side wall of the glaze storage tank 2 is provided with a positioning groove 24 for forming the positioning surface 2d, and the positioning groove 24 is parallel to the overflow edge 21. Depending on the processing precision required, the top surface, bottom surface, or side surface within the positioning groove 24 can be used as the positioning surface.
[0043] Preferably, the glaze delivery pipe 4 can be connected to existing technologies such as a metering pump or a peristaltic pump to control the rate at which glaze slurry is pumped into the glaze storage tank, thereby controlling the overflow rate of the glaze slurry and thus controlling the amount of glaze applied.
[0044] Preferably, the glaze storage tank and the glazing component can be made of corrosion-resistant materials such as stainless steel, or of aluminum alloy with a corrosion-resistant coating on the surface.
[0045] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
