Description

Technical Field

[0001] The invention relates to the technical field of ceramic tile manufacturing, and in particular to a ceramic tile surface glazing device and a glazing method with high flatness. Background Art

[0002] At present, the glazed ceramic tiles on the market not only have rich patterns and images, but also have a smooth and bright surface. They are very popular among consumers due to their rich patterns and clear textures. Glaze is a colorless or colored glassy thin layer covering the surface of ceramic products. It is made by mixing mineral raw materials (feldspar, quartz, talc, kaolin, etc.) and raw materials in a certain proportion (some raw materials can be made into frits first). After grinding, it is made into glaze slurry, applied to the surface of the green body, and calcined at a certain temperature. It can increase the mechanical strength, thermal stability and dielectric strength of the product, and also beautify the objects, facilitate wiping, and prevent erosion by dust and filth. The glazing process refers to the application of glaze slurry on the surface of the pressed ceramic tile body. There are seven main methods: dipping glaze, swinging glaze, pouring glaze, brushing glaze, sprinkling glaze, and wheel glaze. The corresponding glazing method is used according to the different shapes and thicknesses of the green body.

[0003] Traditional glazing requires conveying the pressed ceramic tile to a glazing device, where a layer of glaze is applied to the surface of the tile by spraying or pouring glaze. However, during the pressing process, large clay particles may remain on the surface of the tile, and large dust particles may adhere to the surface of the tile during transportation. If glazing is poured at this stage, the fired tile will have raised particles on the surface, making the surface uneven and affecting the appearance quality of the tile.

[0004] In view of this, the applicant conducted in-depth research on the above issues, which led to the present case. Summary of the Invention

The second air outlet pipe is arranged and installed on the blowing frame. The air outlet end of the second air outlet pipe is inclined toward the conveyor belt. The air inlet pipe of the second air outlet pipe is connected to the second air guide pipe. The air inlet end of the second air guide pipe is connected to the air inlet end of the second fan. The second fan is installed on the conveyor belt.

[0014] Furthermore, the conveyor belt is provided with a liquid storage tank at the front end of the blowing frame, and the conveyor belt is also provided with a drainage pipe connected to the interior of the liquid storage tank, and the liquid outlet end of the drainage pipe is provided with a solenoid valve.

[0017] (2) The conveyor belt is driven by a motor to drive the conveyor chain belt, slowly conveying the ceramic tile blanks, the first fan and the second fan are pneumatically driven, and the first air outlet pipe and the second air outlet pipe blow air to the conveyor belt;

Furthermore, after glazing, the air blowing mechanism blows the glaze slurry on the surface of the tile blank, ensuring that the glaze slurry is evenly dispersed and coated on the surface of the tile blank. This makes the thickness of the glaze layer on the tile blank more uniform and flat after firing, further improving the flatness and product quality of the tile, and making the tile appearance smoother and more beautiful.

[0040] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0041] like Figure 1-7As shown, a device for glazing a ceramic tile surface with high flatness comprises a conveyor belt 1, on which a scraper mechanism 2, a glaze bell 3 and a blowing mechanism 4 are sequentially provided along the feeding direction. The scraper mechanism 2 comprises a scraper frame 21, a mounting frame 22, a pneumatic guide rail 23, a slider 24, a scraper knife 25 and a probe 26. The scraper frame 21 is installed on the conveyor belt 1, and the mounting frame 22 is installed on the front side of the scraper frame 21. The lower end of the mounting frame 22 presents an inverted trapezoidal structure and is provided with a horizontally arranged pushing plate 221. The front end of the pushing plate 221 is provided with a connecting plate 222 arranged upwardly inclined, and the lower end of the connecting plate 222 is provided with a strip hole 223. The lower end of the strip hole 223 is flush with the lower surface of the pushing plate 221. The pneumatic guide rail is arranged side by side on the strip hole 223 in the horizontal direction to ensure that the strip hole 223 can be completely covered by the pneumatic guide rail. The width of the strip hole 223 is greater than the width of the ceramic tile body. The slider 24 is slidably connected to the pneumatic guide rail, which can drive the slider 24 to move laterally. The scraper blade 25 is mounted on the slider 24 and maintained in a horizontal position. The lower surface of the scraper blade 25 is parallel to the lower surface of the push plate 221. The probe 26 is connected above the scraper blade 25. Each probe 26 can detect an image of the upper surface of the tile body and transmit the image information to the processor for processing. After adopting the above structure, when the ceramic tile body is conveyed to the front end of the scraper frame 21, each group of probes 26 can detect the surface flatness of the ceramic tile body and transmit the image information to the processor for processing. When the processor finds that the surface of the ceramic tile body has raised particles, it sends a signal to drive the slider 24 on the pneumatic guide rail 23 on the side where the raised particles are detected to move. The slider 24 drives the scraper 25 to move to the front of the raised particles. In this way, when the ceramic tile body passes through the scraper 25, the raised particles on the upper surface can be scraped off by the scraper 25, and when the ceramic tile body passes through the pushing plate 221, the pushing plate 221 can smooth the scraped parts of the ceramic tile body to ensure that the upper surface of the ceramic tile body remains flat.

[0042] Preferably, the scraper mechanism 2 also includes a first air outlet pipe 27, a first air guide pipe 28 and a first fan 29. The first air outlet pipe 27 is arranged in the mounting frame 22. The middle and upper ends of the first air outlet pipe 27 are respectively connected to the mounting frame 22 and the scraper frame 21. The air outlet end of the first air outlet pipe 27 is set toward the strip hole 223. The air inlet end of the first air outlet pipe 27 is connected to the first air guide pipe 28. The air inlet end of the first air guide pipe 28 is connected to the air outlet end of the first fan 29. The first fan 29 is installed on the conveyor belt 1. After adopting the above structure, the first fan 29 is turned on to blow the gas into the first air guide pipe 28, and then each first air outlet pipe 27 blows the gas out from the lower end of the strip hole 223. Since the lower end of the strip hole 223 is flush with the lower surface of the push plate 221, this can ensure that the wind blown out by the first air outlet pipe 27 can just fully contact the upper surface of the ceramic tile body, ensuring that the raised particles and various small particles after scraping are blown off, so that the upper surface of the ceramic tile body remains clean and flat before pouring the glaze.

[0043] More preferably, in order to ensure that the raised particles can be completely removed, the strip-shaped hole 223 is provided with an inclined surface at the front end of the pushing plate 221, and the inclined surface cooperates with the lower surface of the pushing plate 221 to form a scraping tip 2211. The scraping tip 2211 can perform a secondary scraping on the upper surface of the tile blank to ensure that the raised particles are completely removed.

[0044] Preferably, the conveyor belt 1 includes two parallel conveyor chain belts 11, and the conveyor chain belts 11 are provided with evenly distributed clamping blocks 12. The clamping blocks 12 can limit the position of the tile blanks to prevent the tiles from shifting backward during transportation.

[0045] Preferably, the glaze bell 3 is arranged above the conveyor belt 1, and a feed pipe is connected to the upper end of the glaze bell 3. When pouring glaze, the feed pipe conveys the glaze slurry to the upper surface of the glaze bell 3, and the glaze slurry flows downward along the upper surface of the glaze bell 3, filling the upper surface of the tile body with the glaze slurry.

[0046] In this embodiment, in order to make the glaze slurry distribution more uniform, the glaze bell 3 includes a cover body 31, a liquid guide component and a feed pipe 32. The liquid guide component includes an outer tube cover 33, a diverter net 34, a connecting rod 35, a rotating seat 36 and a micro motor 37. The upper end of the outer tube cover 33 is sleeved on the discharge end of the feed pipe 32. There is a liquid guide gap between the lower end of the outer tube cover 33 and the cover body 31. The diverter net 34 is arranged inside the outer tube cover 33. The diverter net 34 is provided with a plurality of first liquid outlet holes 341. The first liquid outlet holes 341 are gradually inclined from top to bottom toward the outside. The rotating seat 36 is installed on the connecting rod 35. The micro motor 37 is installed in the cover body 31. The upper end of the connecting rod 35 is rotatably connected to the diverter net 34, and the lower end of the connecting rod 35 is connected to the power output end of the micro motor 37.

[0047] Specifically, a liquid guide hole 342 is provided in the middle of the diversion net 34. The upper end of the connecting rod 35 extends into the liquid guide hole 342. An arc-shaped liquid guide surface 343 is provided in the liquid guide hole 342, gradually tilting toward the connecting rod 35. Large particles or glaze slurry with a higher viscosity can flow to the connecting rod 35 through the liquid guide hole 342, and then be guided by the connecting rod 35 to finally flow into the arc-shaped groove of the rotating seat 36, and then be directed to the cover body 31 through the second liquid outlet hole 362. The upper surface of the rotating seat 36 is provided with an annular groove 361. The bottom cross-section of the annular groove 361 is arc-shaped to facilitate the downward flow of the glaze slurry. The lower end of the rotating seat 36 is provided with a plurality of second liquid outlet holes 362, and the liquid inlet end of the second liquid outlet hole 362 is connected to the bottom of the arc-shaped groove. A plurality of liquid guide tubes 363 are provided on the base of the rotating seat 36. The liquid guide tubes 363 extend along an arc shape. The liquid outlet direction of the liquid guide tubes 363 is tangent to the upper surface of the cover body 31, so that the glaze slurry can be sprayed horizontally and attached to the surface of the cover body 31, reducing the impact force on the cover body 31, preventing the cover body 31 from shaking, and further improving the stability of the cover body 31 during pouring glaze.

[0048] By adopting the above structure, the glaze bell jar 3 of the present invention can be used to disperse glaze slurries of different consistencies. When the glaze slurry has a low consistency, the glaze slurry flows out from the feed pipe 32, and a large amount of glaze slurry can be directly diverted through the diversion net 34. The glaze slurry can be diverted and ejected onto the jar body 31 through the first liquid outlet 341, so that the force on the jar body 31 is more uniform. In addition, a small amount of glaze slurry can also be diverted to the rotating seat 36 through the liquid guide hole 342. The glaze slurry is dispersed and transported by the rotation of the rotating seat 36, thereby ensuring that the glaze slurry is distributed more evenly and fully. When the glaze slurry has a high consistency, the diversion speed of the first liquid outlet 341 is slow, and most of the glaze slurry can be deposited on the diversion net 34 and quickly diverted to the rotating seat 36 through the liquid guide hole 342. The glaze slurry is quickly thrown out of the second liquid outlet 362 by the rotation of the rotating seat 36, thereby improving the dispersion and transportation efficiency of the glaze slurry. When processing exterior wall tiles, the glaze bell cover 3 can directly replace glaze slurries of different consistencies for glazing processing and debugging, ensuring that the glaze slurry can be evenly scattered on the cover body 31, further improving the uniformity and stability of the glazing.

[0049] Specifically, the glaze bell 3 further includes a fixing rod 381 and a mounting rod 382. One end of the fixing rod 381 is connected to the conveyor belt 1 and the other end is connected to the interior of the bell body 31. One end of the mounting rod 382 is connected to the conveyor belt 1 and the other end extends below the bell body 31. The micro motor 37 is mounted on the mounting rod 382. The above structure makes it easier to install the bell body 31 and the micro motor 37, and facilitates replacement and maintenance.

[0050] Preferably, the blowing mechanism 4 includes a blowing frame 41, a second air outlet pipe 42, a second air guide pipe 43, and a second fan 44. The blowing frame 41 is mounted on the conveyor belt 1, and the second air outlet pipe 42 is arranged in parallel on the blowing frame 41. The outlet end of the second air outlet pipe 42 is tilted toward the conveyor belt 1. The air inlet pipe of the second air outlet pipe 42 is connected to the second air guide pipe 43. The air inlet end of the second air guide pipe 43 is connected to the air inlet end of the second fan 44. The second fan 44 is mounted on the conveyor belt 1. The conveyor belt 1 is provided with a liquid storage tank 45 at the front end of the blowing frame 41. The conveyor belt 1 is also provided with a drain pipe 46 that is connected to the interior of the liquid storage tank 45. The liquid outlet end of the drain pipe 46 is provided with a solenoid valve. After adopting the above structure, the second air outlet pipe 42 blows a large amount of glaze slurry on the tile body backward, so that the glaze slurry on the upper surface of the tile body can be evenly distributed, and the adhesion thickness of the glaze slurry is more uniform and flat. The excess glaze slurry is dropped into the liquid storage tank 45 for recovery, thereby saving costs.

[0051] A glazing method comprises the following steps:

[0052] (1) The pressed ceramic tile body is conveyed to an oven for preliminary drying, and then the dried ceramic tile body is conveyed to a conveyor belt 1;

[0053] (2) The conveyor belt 1 is driven by the motor-driven conveyor chain 11 to slowly convey the ceramic tile bodies. The first fan 29 and the second fan 44 are pneumatically driven, and the first air outlet pipe 27 and the second air outlet pipe 42 blow air to the conveyor belt 1;

[0054] (3) When the ceramic tile body is transported to the front of the scraper frame 21, each group of probes 26 detects the upper surface of the ceramic tile body in front and transmits the detected image to the processor;

[0055] (4) When there are raised particles on the surface of the ceramic tile body, the detected image is detected by the processor and a signal is sent to drive the slider 24 on the pneumatic guide rail 23 on the side where the raised particles are detected to move. The slider 24 drives the scraper 25 to move to the front of the raised particles.

[0056] (5) The conveyor belt 1 transports the ceramic tile body through the scraping knife 25, which scrapes off the raised particles on the upper surface of the ceramic tile body. The scraped raised particles are then blown off by the air blown out by the first air outlet pipe 27. The ceramic tile body is then transported forward and passed through the pushing plate 221. The pushing plate 221 flattens the surface of the ceramic tile body so that the scraped portion of the ceramic tile body can be smoothed, thereby ensuring the flatness of the upper surface of the ceramic tile body.

[0057] (6) The ceramic tile body is transported by the conveyor belt 1 through the glaze bell 3, and the glaze bell 3 evenly pours the glaze slurry on the upper surface of the ceramic tile body;

[0058] (7) The glazed ceramic tile body is transported to the blowing mechanism 4, and the second air outlet pipe 42 blows air to blow a large amount of glaze slurry on the ceramic tile body backward, so that the glaze slurry on the upper surface of the ceramic tile body can be evenly distributed, and the thickness of the glaze slurry is more uniform and flat, and the excess glaze slurry is dropped into the liquid storage tank 45 for recovery;

[0059] (8) Conveyor belt 1 continues to transport the ceramic tile bodies to the downstream process for firing and shaping.

[0060] Compared with the prior art, the present invention has the following advantages: before glazing, the scraper mechanism 2 removes raised particles from the upper surface of the tile blank, and flattens the surface of the tile blank after the raised particles are removed, ensuring that the upper surface of the tile blank remains flat before glazing. Furthermore, after glazing, the air blowing mechanism 4 blows the glaze slurry on the surface of the tile blank, ensuring that the glaze slurry is evenly dispersed and coated on the surface of the tile blank. This makes the thickness of the glaze layer on the tile blank more uniform and flat after firing, further improving the flatness and product quality of the tile, and making the tile appearance smoother and more beautiful.

[0061] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
