Description

[0002] In the ceramic production process, glazing technology refers to the process of applying glaze slurry on the surface of formed ceramic tiles. Glazing methods include throwing glaze, spraying glaze, pouring glaze, etc.

[0003] At present, most of the ceramic tile glazing devices used in the industry are bell-type glaze showers. The bell-type glaze shower allows the glaze slurry in the glaze storage tank to flow naturally onto the bell by gravity, and then the glaze slurry distributed on the bell flows downward naturally. When the ceramic tile passes under the bell, the glaze slurry is poured onto its surface to achieve glazing.

[0004] When using a bell-type glaze applicator to apply glaze, the glaze slurry flows downward naturally, so it is difficult to control the glaze slurry poured onto the ceramic tile blank, resulting in uneven glazing amount on the surface of the ceramic tile blank.

[0053] Embodiment 1:

[0054] See also Figure 1 and Figure 2 , an atomizing glazing nozzle, which includes: a glaze tube profile 100 and at least one atomizing nozzle module 200, the glaze tube profile 100 includes a glaze inlet main pipe 110 and a glaze outlet main pipe 120, the atomizing nozzle module 200 is installed on the glaze tube profile 100, the atomizing nozzle module 200 includes a module box body 300, a first liquid inlet pipe 210, a first liquid outlet pipe 220 and a glazing nozzle 400, the module box body 300 has a liquid storage cavity 500, the liquid storage cavity 500 is connected to the glaze inlet main pipe 110 through the first liquid inlet pipe 210, the liquid storage cavity 500 is connected to the glaze outlet main pipe 120 through the first liquid outlet pipe 220, and a plurality of glazing nozzles 400 arranged in a straight line are arranged on the module box body 300, and each glazing nozzle 400 is connected to the liquid storage cavity 500.

[0055] In the prior art, when a bell-shaped glazing device is used for glazing, since the glaze slurry naturally flows downward, it is not easy to control the glaze slurry poured onto the ceramic tile blank, resulting in uneven glazing amount on the surface of the ceramic tile blank. In the actual production process, the glaze layer in the middle of the glazed surface is often thin and the glaze layer on both sides is thick, which will affect the glaze decorative effect of the ceramic tile blank. In view of this, the present embodiment sprays glaze through the glazing nozzle 400 of the atomizing nozzle module 200. Specifically, the atomizing nozzle module 200 sprays glaze through a plurality of glazing nozzles 400 arranged in a straight line, which is equivalent to the ceramic tile blank being sprayed with glaze by a plurality of glazing nozzles 400 arranged in a straight line at the same time to complete the glazing of the ceramic tile blank. When the ceramic tile blank passes through the atomizing glazing nozzle, several glazing nozzles 400 arranged in a straight line spray glaze on the ceramic tile blank at the same time. The amount of glaze sprayed by each glazing nozzle 400 is consistent and the rate is consistent. Therefore, the glazing on the entire surface of the ceramic tile blank is also uniform, avoiding the phenomenon of inconsistent glazing thickness on the two sides and the middle of the ceramic tile blank. At the same time, the glazing amount of the ceramic tile blank can also be accurately controlled by the glazing nozzle 400, thereby achieving precise control of the glazing thickness of the ceramic tile blank, thereby improving the glaze decorative effect of the ceramic tile blank.

[0056] Therefore, this embodiment uses a plurality of glazing nozzles 400 arranged in a straight line to spray glaze, thereby solving the problem of difficulty in controlling the amount and thickness of glazing on the sides and middle of the tile, thereby improving the glazing effect and further enhancing the glaze decorative effect of the ceramic tile blank.

[0057] In this embodiment, at least one atomizing nozzle module 200 is installed on the glaze tube profile 100. For example, one atomizing glazing nozzle can be connected to the glaze tube profile 100 by one atomizing nozzle module 200. One atomizing glazing nozzle can also be connected to the glaze tube profile 100 by multiple atomizing nozzle modules 200. For example, multiple atomizing nozzle modules 200 are installed in parallel on the glaze tube profile 100. Figure 1, various non-limiting embodiments of the present invention are described in detail by taking an atomizing glazing nozzle including a plurality of atomizing nozzle modules 200 as an example.

[0058] See also Figure 1 The glaze tube profile 100 includes a glaze inlet main pipe 110 and a glaze outlet main pipe 120. The glaze inlet main pipe 110 is used to transport glaze slurry to multiple atomizing nozzle modules 200, and the glaze outlet main pipe 120 is used to recycle the glaze slurry used by the multiple atomizing nozzle modules 200. The glaze inlet main pipe 110 forms a cycle with the glaze outlet main pipe 120 through the atomizing nozzle modules 200. This process helps to maintain the circulation and renewal of the glaze slurry in the system, and can effectively regulate the pressure in the system to avoid damage to the glazing nozzle 400 or a decrease in efficiency due to excessively high or low pressure, and can also reduce the waste of glaze slurry. , which can reduce the power required by the glaze supply pump 710 to transport the glaze slurry, reduce energy consumption, improve system efficiency, and increase response speed, so that the glaze slurry can quickly respond to the needs of the atomizing nozzle module 200 and improve the dynamic performance of the system. In addition, the glaze outlet main pipe 120 helps to discharge the air in the atomizing nozzle module 200 to prevent bubbles from accumulating in the glaze slurry and affecting the spraying effect. Through the circulation of the glaze inlet main pipe 110 and the glaze outlet main pipe 120, the concentration of the glaze slurry can be kept stable, the bubble content in the glaze can be reduced, thereby reducing the water content of the glaze slurry and improving the spraying effect of the glaze slurry.

[0059] See also Figure 1 and Figure 2 The atomizing nozzle module 200 includes a module box body 300, a first liquid inlet pipe 210, a first liquid outlet pipe 220 and a glazing nozzle 400. The liquid storage chamber 500 of the module box body 300 is connected to the glaze inlet main pipe 110 via the first liquid inlet pipe 210, and the liquid storage chamber 500 is connected to the glaze outlet main pipe 120 via the first liquid outlet pipe 220. For example, the first liquid inlet pipes 210 of the multiple atomizing nozzle modules 200 are arranged in parallel with the glaze inlet main pipe 110, and the first liquid outlet pipes 220 of the multiple atomizing nozzle modules 200 are arranged in parallel with the glaze outlet main pipe 120, so that the liquid storage chambers 500 of the multiple atomizing nozzle modules 200 are connected via the first liquid inlet pipe 210, the first liquid outlet pipe 220, the glaze inlet main pipe 110 and the glaze outlet main pipe 120 to form a glaze slurry circulation, which helps to maintain the circulation and renewal of the glaze slurry in the liquid storage chamber 500, can maintain the stability of the glaze slurry concentration in the liquid storage chamber 500, improve the spraying effect of the glazing nozzle 400, and ensure the glazing quality of the glazing nozzle 400.

[0060] See also Figure 2, a plurality of glazing nozzles 400 arranged in a straight line are provided in the module box body 300. It can be understood that the plurality of glazing nozzles 400 are evenly arranged in the module box body 300, and the spacing between two adjacent glazing nozzles 400 is consistent. When the ceramic tile blank passes under the atomizing glazing nozzle, since the spacing between two adjacent glazing nozzles 400 is consistent, and the glazing amount and speed of each glazing nozzle 400 are consistent, the glazing on the surface of the ceramic tile blank is also uniform, avoiding the phenomenon of inconsistent glazing thickness on both sides and the middle of the ceramic tile blank. At the same time, the glazing amount of the ceramic tile blank can also be accurately controlled by the glazing nozzle 400, thereby achieving accurate control of the glazing thickness of the ceramic tile blank.

[0061] Specifically, see Figure 1 The atomizing glazing nozzle also includes a nozzle bracket 600, which includes a left side plate 610, a supporting bottom plate 630 and a right side plate 620. One end of the left side plate 610 is fixedly connected to the left side of the glaze tube profile 100, and the other end of the left side plate 610 is connected to the left side of the supporting bottom plate 630. One end of the right side plate 620 is fixedly connected to the right side of the glaze tube profile 100, and the other end of the right side plate 620 is connected to the right side of the supporting bottom plate 630.

[0062] In this embodiment, the glaze tube profile 100 is mainly used to provide glaze slurry to the atomizing nozzle module 200 and recycle glaze slurry, and the left side of the glaze tube profile 100 is connected to the left side plate 610 of the nozzle bracket 600, and the right side of the glaze tube profile 100 is connected to the right side plate 620 of the nozzle bracket 600. The nozzle bracket 600 is used to install the atomizing nozzle module 200. It can be understood that the glaze tube profile 100 is a part of the nozzle bracket 600. Therefore, the glaze tube profile 100 also has the function of supporting or fixing the atomizing nozzle module 200. Its structure is compact, which is conducive to the miniaturized design of the atomizing glazing nozzle, and can provide avoidance space for glazing the atomizing glazing nozzle.

[0063] See also Figure 1 At least two rows of atomizing nozzle modules 200 are arranged on the supporting bottom plate 630, and the atomizing nozzle modules 200 in two adjacent rows are arranged alternately.

[0064] In the present embodiment, the spacing between the glazing nozzles 400 in a single atomizing nozzle module 200 is consistent. However, when installing the atomizing nozzle module 200, the spacing between the glazing nozzles 400 at the junction of two adjacent atomizing nozzle modules 200 may be too large due to the installation size or the wall thickness of the atomizing nozzle module 200 itself. Therefore, two adjacent rows of atomizing nozzle modules 200 are staggered to avoid the defect of excessive spacing between the glazing nozzles 400 at the junction of two adjacent atomizing nozzle modules 200. This allows the glazing nozzles 400 of two adjacent atomizing nozzle modules 200 to be seamlessly connected, and the spacing at the junction is consistent, which can ensure uniform glazing and avoid the phenomenon of inconsistent glazing thickness on ceramic tiles.

[0065] Specifically, see Figure 2 and Figure 3 The module box body 300 includes: a module base 310, a base opening 320, a base cover 330, a base long hole 340 and a nozzle mounting plate 350; the module base 310 has a liquid storage chamber 500, the left side of the module base 310 is connected to the first liquid inlet pipe 210, and the right side of the module base 310 is connected to the first liquid outlet pipe 220. The base opening 320 is arranged at the top of the module base 310, the base cover 330 is sealed and fixedly connected to the module base 310, the base cover 330 is used to close the base opening 320, the base long hole 340 is opened at the bottom of the module base 310, the nozzle mounting plate 350 is sealed and fixedly connected to the module base 310, and the nozzle mounting plate 350 is closed to the base long hole 340, and a plurality of glazing nozzles 400 arranged in a straight line are installed on the nozzle mounting plate 350.

[0066] In this embodiment, the liquid storage chamber 500 can store a certain amount of glaze slurry, so that the glaze slurry can quickly respond to the needs of the glazing nozzle 400, thereby improving the dynamic performance of the system, and the liquid storage chamber 500 forms a circulation system through the first liquid inlet pipe 210 and the first liquid outlet pipe 220, which helps to maintain the circulation and renewal of the glaze slurry in the liquid storage chamber 500, can effectively adjust the pressure in the liquid storage chamber 500, can maintain the stability of the glaze slurry concentration, and improve the spraying effect of the glaze slurry.

[0067] The module base 310 has a liquid storage cavity 500, a base opening 320 and a base long hole 340. The base cover plate 330 is used to close the base opening 320. The nozzle mounting plate 350 is closed to the base long hole 340. The structure is simple and easy to implement, which can reduce the difficulty of production and save costs. In addition, the base cover plate 330 and the nozzle mounting plate 350 can be used for maintenance or replacement of the module base 310. Among them, a plurality of glazing nozzles 400 arranged in a straight line are installed on the nozzle mounting plate 350, which is convenient for disassembly and assembly, and is convenient for maintenance and replacement of the glazing nozzles 400. For example, when the glazing nozzle 400 needs to be replaced, the nozzle mounting plate 350 is disassembled, and then any designated glazing nozzle 400 can be replaced on the nozzle mounting plate 350.

[0068] Specifically, see Figure 2 and Figure 4 The module box body 300 also includes: a first sealing ring 370 and a second sealing ring 380, the first sealing ring 370 is located between the module base 310 and the base cover 330, and the module base 310 is provided with a first groove 311 for accommodating the first sealing ring 370, the second sealing ring 380 is located between the module base 310 and the nozzle mounting plate 350, and the module base 310 is provided with a second groove 312 for accommodating the second sealing ring 380.

[0069] In this embodiment, the first sealing ring 370 and the second sealing ring 380 are both used for the sealed connection of the module base 310, so as to realize the sealed connection between the module base 310 and the base cover plate 330, and the module base 310 and the nozzle mounting plate 350, with a simple structure, convenient disassembly and assembly, and convenient maintenance. For example, the module base 310 and the base cover plate 330 can be fixedly connected by a plurality of bolts, and the module base 310 and the nozzle mounting plate 350 can also be fixedly connected by a plurality of bolts, which is easy to realize, reduces the difficulty of production, saves production costs, is convenient to disassemble and assemble, and is easy to maintain.

[0070] Specifically, see Figure 2 and Figure 5 A strip groove 360 ​​is provided in the middle of the nozzle mounting plate 350 , and one or more rows of glazing nozzles 400 arranged in a straight line are provided in the strip groove 360 ​​.

[0071] In this embodiment, the strip groove 360 ​​can place the glazing nozzle 400 at a lower position, so that the glaze slurry in the liquid storage chamber 500 can be smoothly sprayed out through the glazing nozzle 400, avoiding the glaze slurry from being deposited in the liquid storage chamber 500, ensuring the glazing effect, and improving the glaze decoration effect of the ceramic tile blank.

[0072] Specifically, see Figure 5, three rows of glazing nozzles 400 arranged in a straight line are arranged in the strip groove 360, the glazing nozzles 400 are circular hole nozzles, and the distance L between the center holes of two adjacent glazing nozzles 400 in a row is 2-5mm, and the glazing height H of the glazing nozzles 400 is 20-50mm ( Fig. 9 ).

[0073] In the conventional technology, a bell jar glazing device is usually used for glazing. The bell jar glazing device has a large glazing amount and a high water content of the ceramic body, which causes the ceramic body to be easily deformed and cracked. In the present embodiment, a glazing nozzle 400 is used for glazing. The airless pressure atomization technology is used to reduce the dust generated when the glaze slurry is atomized, and the water content of the glaze slurry can be reduced, and the hidden danger of water infiltrating into the ceramic body and cracking after the ceramic body is glazed can be reduced. In order to avoid the mutual influence of each glazing nozzle 400 and avoid the generation of glaze spraying ripples between the glazing nozzles 400, it is necessary to control the spacing L between the center holes of adjacent glazing nozzles 400 and the glazing height H of the glazing nozzles 400. For this purpose, the atomizing nozzle module 200 is set to at least two rows, and the spacing L between the center holes of two adjacent glazing nozzles 400 in one row should not be too large. If the spacing L between the center holes is large, glaze spraying ripples will be generated.

[0074] Specifically, the spacing L between the center holes of two adjacent glazing nozzles 400 in a row is 2-5 mm, and the glazing height H of the glazing nozzles 400 is 20-50 mm. Preferably, the spacing L between the center holes of two adjacent glazing nozzles 400 in a row is 3 mm. During the debugging process, the spacing L between the center holes of two adjacent glazing nozzles 400 is 3 mm, and the glazing effect is more delicate, and no glazing ripples are generated. For example, three rows of glazing nozzles 400 arranged in a straight line are arranged on the support bottom plate 630, and the glazing nozzles 400 arranged in a straight line in the first row are arranged alternately with the glazing nozzles 400 arranged in a straight line in the second row, and the glazing nozzles 400 arranged in a straight line in the second row are arranged alternately with the glazing nozzles 400 arranged in a straight line in the third row, and the spacing L between the center holes of two adjacent glazing nozzles 400 in the same row is 3 mm. The number of glazing nozzles 400 arranged in a straight line in each row can be 60-80, for example, the number of glazing nozzles 400 arranged in a straight line in each row can be 76. The round hole nozzle is a universal nozzle. The glaze slurry is sprayed out from the central hole of the glazing nozzle 400. It has a simple structure and low cost. It is usually used in situations where uniform spraying is required.

[0075] Specifically, see Figure 3 The liquid storage chamber 500 includes: a chamber body 510 and a contraction chamber 520 . The contraction chamber 520 is located on the side of the chamber body 510 close to the long hole 340 of the base. The contraction chamber 520 is used to communicate with the long hole 340 of the base.

[0076] In this embodiment, the liquid storage chamber 500 is connected to the glazing nozzle 400 through the contraction chamber 520. The glaze slurry can flow along the contraction chamber 520 to the glazing nozzle 400, which can avoid the deposition of the glaze slurry in the liquid storage chamber 500 to a certain extent, ensure the glaze spraying effect, and enhance the glaze decorative effect of the ceramic tile blank.

[0077] Specifically, see Figure 3 The shrinkage cavity 520 includes a left side wall 521, a right side wall 522, a front side wall 523 and a rear side wall 524. The left side wall 521, the front side wall 523, the right side wall 522 and the rear side wall 524 are closed and connected in sequence. The left side wall 521 is connected to the first liquid inlet pipe 210, and the right side wall 522 is connected to the first liquid outlet pipe 220. The front side wall 523 and the rear side wall 524 both shrink and move closer from the cavity body 510 to the side of the long hole 340 of the base.

[0078] In this embodiment, the front side wall 523 and the rear side wall 524 both shrink and move closer from the cavity body 510 toward the side of the long hole 340 of the base to form a shrinkage cavity 520, which can prevent the glaze slurry from depositing in the liquid storage cavity 500, ensure the glaze spraying effect, and enhance the glaze decoration effect of the ceramic tile blank.

[0079] Embodiment 2:

[0080] The present application provides an atomizing glazing device, which includes: an atomizing glazing nozzle as described in the above embodiment. Therefore, the atomizing glazing device can have all the features and beneficial effects of the above atomizing glazing nozzle, which will not be described in detail.

[0081] Specifically, see Figure 6 The atomizing glazing device may further include: a pressure control module 700, the pressure control module 700 includes: a glaze supply pump 710, an accumulator 720, a pressure sensor 730 and a PID intelligent pressure regulating system 740, the glaze supply pump 710 is electrically connected to the pressure sensor 730 and the PID intelligent pressure regulating system 740, respectively, and the glaze supply pump 710 is connected to the glaze supply main pipe 110 via the accumulator 720.

[0082] In this embodiment, PLC750 is electrically connected to glaze supply pump 710, pressure sensor 730, accumulator 720 and PID intelligent pressure regulating system 740 respectively. Glaze supply pump 710 can continuously provide glaze slurry for glaze tube profile 100 of atomizing glazing nozzle. Accumulator 720 is located between glaze supply pump 710 and glaze tube profile 100. Accumulator 720 is used for stable operation of glazing system. Accumulator 720 can automatically adjust energy output according to actual working conditions to adapt to different working conditions and environmental changes. In a system that needs frequent start and stop, accumulator 720 can reduce equipment wear and energy consumption and extend service life.

[0083] The pressure sensor 730 is used to monitor the hydraulic condition of the glaze supply pump 710 in real time. The PID intelligent pressure regulation system 740 is an intelligent system that uses a proportional-integral-differential (PID) control algorithm to accurately adjust the glaze slurry pressure. The PID intelligent pressure regulation system 740 can adjust the output signal according to the real-time feedback pressure data to achieve precise control of the oil supply pressure. Through a closed-loop control system, the PID intelligent pressure regulation system 740 can continuously monitor and adjust the glaze slurry pressure to ensure that it is stable near the set value. The PID intelligent pressure regulation system 740 helps to reduce energy waste, improve energy efficiency, extend the service life of mechanical equipment, and reduce maintenance costs.

[0084] Specifically, see Figure 7 and Figure 8 The atomizing glazing device may also include: a glaze slurry purification and filtering module 800 and a frame module 900. The glaze slurry purification and filtering module 800 includes a cleaning device 810, a high-frequency vibration filtering tank 830, a buffer glaze tank 820, and a working glaze slurry tank 840. The cleaning device 810 is connected to the glaze inlet main pipe 110. The cleaning device 810 is used to clean the glazing nozzle 400. The working glaze slurry tank 840 is connected to the glaze inlet main pipe 110. The working glaze slurry tank 840 is used to provide glaze slurry to the glaze inlet main pipe 110. The high-frequency vibration filtering tank 830 is connected to the glaze outlet main pipe 120 via the buffer glaze tank 820. The buffer glaze tank 820 is used to recover the glaze slurry from the glaze outlet main pipe 120. The high-frequency vibration filtering tank 830 is used to return the glaze slurry from the buffer glaze tank 820 to the working glaze slurry tank 840.

[0085] In this embodiment, the cleaning device 810 can effectively remove solid particles and bubbles in the glaze to prevent these impurities from affecting the quality and appearance of the final product. Regular cleaning and maintenance help to extend the service life of the equipment and reduce the failure rate.

[0086] The high-frequency vibration filter tank 830 filters the glaze by means of high-frequency vibration to remove impurities and bubbles therein, thereby improving the purity of the glaze and reducing defects in the glazing process.

[0087] The buffer glaze tank 820 is used to temporarily store the filtered and adjusted glaze so that it can be returned to the working glaze slurry tank 840 at any time through the high-frequency vibration filter tank 830. The buffer glaze tank 820 can ensure the stability and continuity of the glaze supply and avoid affecting the production process due to insufficient glaze supply.

[0088] The working glaze slurry tank 840 is used to store the prepared glaze slurry for use by the atomizing glazing nozzle. The working glaze slurry tank 840 is usually equipped with a stirring and heating device to ensure the uniformity and appropriate viscosity of the glaze slurry.

[0089] It can be seen that the cleaning device 810, the high-frequency vibration filter tank 830, the buffer glaze tank 820, and the working glaze slurry tank 840 work together to efficiently complete the cleaning, recovery, filtering, and glaze supply processes, which not only improves the efficiency and quality of glazing, but also promotes the automation and intelligence of the entire production process.

[0090] The rack module 900 includes a conveying rack 910 and a lifting rack 920 disposed on the conveying rack 910;

[0091] See also Fig. 9 A servo motor 911, a main drive roller 912, a passive roller 913 and a drive belt 914 are installed on the conveyor frame 910. The drive belt 914 is wound between the main drive roller 912 and the passive roller 913. The servo motor 911 is drivingly connected to the main drive roller 912.

[0092] See also Fig.10 The lifting frame 920 includes: a lifting module 930 and a rotating module 940. The lifting module 930 includes a lifting base 931, a vertical slide rail 932, a lifting slider, a lifting mounting plate and a lifting motor 933. The lifting base 931 is fixed to the conveying frame 910. The lifting base 931 is provided with a vertical slide rail 932. The vertical slide rail 932 is slidably connected to the lifting slider. The lifting mounting plate is fixedly connected to the lifting slider, and the lifting motor 933 is drivingly connected to the lifting mounting plate.

[0093] The rotating module 940 includes: a rotating base 941, a rotating motor 942 and a nozzle base 943. The rotating base 941 is fixed to the lifting mounting plate. The nozzle base 943 is rotatably connected to the rotating base 941, and the rotating motor 942 is drivingly connected to the nozzle base 943. An atomizing glazing nozzle is installed on the nozzle base 943.

[0094] In this embodiment, the servo motor 911 can drive the main drive roller 912 to rotate, and the main drive roller 912 drives the drive belt 914 to rotate. The drive belt 914 is used to drive the ceramic tile blanks to pass under the atomizing glazing nozzle. When the ceramic tile blanks are placed under the atomizing glazing nozzles, the atomizing glazing nozzles spray glaze on the ceramic tile blanks through a plurality of glazing nozzles arranged in a straight line, so as to solve the problem that the thickness of the glaze on the left, middle and right of the ceramic tile blanks is difficult to control.

[0095] The lifting motor 933 is used to drive the atomizing glazing nozzle to move up and down along the vertical slide rail 932 to adjust the height of the atomizing glazing nozzle. For example, when the height between the atomizing glazing nozzle and the ceramic tile needs to be adjusted, the lifting motor 933 can be used to drive the lifting mounting plate to move up and down along the vertical slide rail 932 to ensure that the atomizing glazing nozzle achieves the best glazing effect. As described above, the glazing height H of the glazing nozzle 400 is preferably controlled to be 20-50mm. Due to the different water content of the glaze slurry and the different spacing L between the center holes of two adjacent glazing nozzles 400, correspondingly, in order to achieve a good glazing effect, the glazing height H of the glazing nozzle 400 needs to be adjusted accordingly.

[0096] The rotating motor 942 is used to drive the atomizing glazing nozzle to rotate. For example, when the atomizing glazing nozzle needs to be maintained, the atomizing glazing nozzle can be driven to rise to a certain position by the lifting motor 933. Then the rotating motor 942 can drive the atomizing glazing nozzle to rotate 180°, so that the atomizing glazing nozzle is exposed on the rack module 900 for maintenance operations.

[0097] In summary, the present application discloses an atomizing glazing nozzle and an atomizing glazing device, wherein the atomizing glazing nozzle comprises a glaze tube profile and at least one atomizing nozzle module, the glaze tube profile comprises a glaze inlet main pipe and a glaze outlet main pipe, the atomizing nozzle module comprises a module box body, a first liquid inlet pipe, a first liquid outlet pipe and a plurality of glazing nozzles arranged in a straight line, the module box body has a liquid storage cavity, the liquid storage cavity is connected to the glaze inlet main pipe through the first liquid inlet pipe, the liquid storage cavity is connected to the glaze outlet main pipe through the first liquid outlet pipe, the glazing nozzle is arranged in the module box body, and the glazing nozzle is connected to the liquid storage cavity. The present application sprays glaze through a plurality of glazing nozzles arranged in a straight line, thereby solving the problem that the glazing amount and the thickness of the ceramic tile on both sides and in the middle are not easy to control, so as to improve the glazing effect, and thus improve the glaze decoration effect of the ceramic tile blank.
