[0060] One embodiment of the present invention provides a glaze spraying control method based on a glaze spraying device, such as Figures 1 to 3 As shown, the glaze spraying device further includes a first container 200, a second container 300, a glaze dispenser 410, a plurality of glaze spraying valves 420, an infusion device 500 and a valve assembly.

[0061] The first container 200 has a first air inlet 240, a first exhaust port 250 and a liquid inlet 260. The second container 300 has a second air inlet 340 and a second exhaust port 350; the first air inlet 240, the first exhaust port 250, the second air inlet 340 and the second exhaust port 350 are all connected to the valve assembly, so that the valve assembly opens or closes the first air inlet 240, the first exhaust port 250, the second air inlet 340 and the second exhaust port 250.

[0062] Optionally, the valve assembly includes two three-position four-way valves, but is not limited to the above valves, and may also be other valves with similar functions. Taking the three-position four-way valve as an example, one of the three-position four-way valves is connected to the first air inlet interface 240 and the first air exhaust interface 250, and the other three-position four-way valve is connected to the second air inlet interface 340 and the second air exhaust interface 350. Alternatively, the first air inlet interface 240 and the second air inlet interface 340 are connected to the same valve, and the first air exhaust interface 250 and the second air exhaust interface 350 are connected to the same valve.

[0063] Preferably, the valve assembly includes a first air intake valve 210, a first exhaust valve 220, a second air intake valve 310 and a second exhaust valve 320, and the first air intake valve 210, the first exhaust valve 220, the second air intake valve 310 and the second exhaust valve 320 are respectively connected to the first air intake interface 240, the first exhaust interface 250, the second air intake inlet 340 and the second exhaust interface 350 to control the opening or closing of the air intake and exhaust of the above-mentioned interfaces one-to-one.

[0064] The infusion device 500 is connected to the first container 200 via the liquid inlet interface 260. The infusion device 500 has a first suction port 510 and a first outlet 520. The first outlet 520 is connected to the liquid inlet interface 260. The first suction port 510 is connected to a glaze storage container (e.g., a glaze bucket) when glaze is input, and is switched to a clean liquid storage container (e.g., a bucket) when a clean liquid is input. The infusion device 500 can be an infusion pump, or a device that inputs liquid in other forms, such as a device that presses liquid into the first container 200 by air pressure or hydraulic pressure.

[0065] In more detail, the first container 200 and the second container 300 are closed containers, such as cans, and are preferably arranged side by side so that a plurality of glaze spraying modules 400 can be arranged along the length direction of the first container 200 and the second container 300. The first air inlet valve 210, the first exhaust valve 220, the second air inlet valve 310 and the second exhaust valve 320 are preferably two-way valves.

[0066] like Figure 6 As shown, a plurality of glaze spraying valves 420 are arranged on the glaze distributor 410 to form a glaze spraying module 400. The glaze spraying module 400 can be one or more than one, preferably multiple, to realize digital glaze spraying printing and obtain a glaze spraying pattern. The glaze distributor 410 has a conveying channel 411, and the first container 200 is connected to the second container 300 through the conveying channel 411. Specifically, the glaze distributor 410 is a plate-shaped structure, and the conveying channel 411 is formed in the glaze distributor 410. The two ends of the conveying channel 411 are respectively connected to the first communication interface 270 at the bottom of the first container 200 and the first communication interface 370 at the bottom of the second container 300 through a pipe 430. The glaze distributor 410 is provided with a plurality of glaze spraying holes 412 connected to the conveying channel 411. The glaze spraying holes 412 are preferably arranged on the lower side of the glaze distributor 410. When there are multiple glaze spraying holes 412, the multiple glaze spraying holes 412 are spaced apart along the extension direction of the conveying channel 411. The plurality of glaze spraying valves 420 respectively control the opening and closing states of the plurality of glaze spraying holes 412 .

[0067] For example, Figure 6As shown, the glaze spray valve 420 is a needle valve. In more detail, the glaze spray valve 420 includes a housing 421, a coil 422, a valve core 423 and a spring 424. The coil 422 and the valve core 423 are arranged in the housing 421, and one end of the valve core 423 extends into the coil 422. When the coil 422 is energized, the magnetic field generated can make the valve core 423 retract backward. A guide sleeve 425 is fixed in the housing 421. A limiting convex part 426 is arranged on the side of the valve core 423. The limiting convex part 426 is located at the front side of the guide sleeve 425. The two ends of the spring 424 are respectively abutted against the limiting convex part 426 and the guide sleeve 425. The valve core 423 passes through the guide sleeve 425, the spring 424 and the limiting convex part 426 in sequence. The spring 424 drives the valve core 423 to extend forward when it is reset. In this way, the valve core 423 can be retracted and movable. A plugging member 427 is provided at the front end of the valve core 423. When the valve core 423 extends forward, the plugging member 427 blocks the glaze spraying hole 412. When the valve core 423 retracts backward, the plugging member 427 and the glaze spraying hole 412 are separated, and the glaze is sprayed out from the glaze spraying hole 412. It should be understood that the above is only one structure of the glaze spraying valve 420 and should not be construed as limiting the present invention.

[0068] Furthermore, the valve assembly, the glaze spraying valve 420 and the infusion device 500 are all connected to the glaze spraying controller 100. When the infusion device 500 is a pneumatic diaphragm pump, the infusion device 500 is preferably controlled by the first electromagnetic valve 530.

[0069] like Figure 7 As shown, the glaze spraying control method includes:

[0070] S101, closing the first air inlet interface, the second air inlet interface, and the second air exhaust interface, and opening the first air exhaust interface and the infusion device to input glaze into the first container;

[0071] S102, closing the first exhaust interface, the second air inlet interface and the second exhaust interface, and opening the first air inlet interface to input pressurized gas into the first container, so that the glaze in the first container is pressurized and input into the second container through the delivery channel;

[0072] S103, controlling the opening and closing state of the glaze spraying hole so that the glaze in the conveying channel is sprayed out from the glaze spraying hole.

[0073] Among them, step S101 is the glazing process in the printing preparation process, and step S102 is the gasification process in the printing preparation process. In step S102, the pressure in the glaze conveying process is stable due to the stable pressure of the pressurized gas. In addition, by first inputting the glaze into the first container and then pressurizing the glaze by the pressure of the air pressure, it is possible to avoid the pressure fluctuation caused by the conveying device (such as a pump) directly supplying the glaze to the glaze distributor to affect the glaze spraying effect. Step S103 is the printing process. The glaze spraying control method first inputs the glaze into the first container and then pressurizes the glaze by the pressure of the air pressure, so as to avoid the pressure fluctuation caused by the conveying device (such as a pump) directly supplying the glaze to the glaze distributor to affect the glaze spraying effect. Finally, the glaze spraying valve is controlled to open or close the glaze spraying hole to control the glaze in the conveying channel to spray out from the glaze spraying hole, thereby realizing CNC glaze spraying printing.

[0074] In some embodiments, in order to clean the glaze remaining in the first container 200 and the second container 300 or to prevent the solid matter in the glaze from being deposited, as Figure 8 As shown, the glaze spraying control method also includes:

[0075] S107, opening the first air inlet interface and the second air outlet interface, and closing the first air outlet interface and the second air inlet interface, so that the liquid in the first container is transferred into the second container through the delivery channel;

[0076] S108, opening the second air inlet interface and the first air outlet interface, and closing the second air outlet interface and the first air inlet interface, so that the liquid in the second container is transferred into the first container through the delivery channel.

[0077] Through steps S107 and S108, the liquid is caused to flow back and forth in the first container and the second container; when the liquid is glaze, the purpose of preventing the solid matter in the glaze from being deposited is achieved; when the liquid is a cleaning liquid, steps S107 and S108 are the flushing process in the cleaning process, so that the cleaning liquid is transferred back and forth in the first container and the second container to form a flushing and rinsing effect. Exemplarily, the cleaning liquid can be water or a mixed solution of water and a cleaning agent.

[0078] By executing step S107 and step S108, the cleaning liquid can be transferred back and forth between the first container 200 and the second container 300, thereby flushing the glaze remaining on the first container 200, the second container 300 and the glaze spraying module 400, and achieving high cleaning. Preferably, step S107 and step S108 can be repeated for more than one cycle. After completing the above cleaning steps, the cleaning liquid is drained away.

[0079] In some embodiments, Fig. 9 As shown, the glaze spraying control method also includes:

[0080] S105, opening the first air inlet interface and / or the second air inlet interface and the glaze spraying hole in sequence, and closing the first exhaust interface and the second exhaust interface, so as to input pressurized gas into the first container and the second container, so that the glaze in the first container and the second container flows out from the glaze spraying hole;

[0081] S106, closing the glaze spraying hole, the first air inlet interface, the second air inlet interface and the second exhaust interface, and opening the first exhaust interface and the infusion device to input liquid into the first container, the liquid being a clean liquid.

[0082] Among them, step S105 is a material clearing process in the cleaning process, and the function of step S105 is to drain the glaze in the first container and the second container, but some glaze still remains in the first container, the second container and the glaze spraying module. Step S106 is a water adding process in the cleaning process.

[0083] In some embodiments, Figure 2 and Figure 3 As shown, the glaze spraying equipment also includes a circulation device 600 and a homogenizing device. The circulation device 600 has a second suction port 610 and a second output port 620. The second suction port 610 is connected to the discharge interface 360 ​​of the second container 300, and the second output port 620 is connected to the homogenizing device 800. The homogenizing device 800 receives the extracted glaze and homogenizes the glaze. The circulation device 600 at least includes a circulation pipeline for transferring the glaze. Preferably, the circulation device 600 also includes a circulation pump (for example, a pneumatic diaphragm pump), and can also be other forms of liquid extraction equipment or combined devices. That is, the circulation device 600 is not necessarily a pump, and the glaze can also be discharged by inputting pressurized gas through the first air inlet valve 210 and / or the second air inlet valve 310.

[0084] like Fig. 9 As shown, in order to make the properties of the glaze in the first container and the second container consistent with the glaze properties of the external glaze supply device, the glaze spraying control method also includes:

[0085] S104, start the circulation device to draw part of the glaze in the first container and the second container and the pipes connected thereto into the homogenizing device for homogenization, and start the infusion device to replenish the glaze into the first container.

[0086] Step S104 is a cyclic process in the glaze spraying method. Homogenization is to make the various components in the glaze mix evenly, maintain the same properties, and avoid the deposition of solid components in the glaze. The homogenized glaze can be transported back to the original first container 200 for continued printing, or stored in a storage container for use by other glaze spraying equipment during printing. The purpose of replenishing the glaze is to keep the first container within a certain liquid level range.

[0087] In some embodiments, Figure 1As shown, the glaze spraying device also includes a liquid level monitoring device 280, which is arranged in the first container 200 to monitor the liquid level of the glaze in the first container 200. The glaze spraying device also includes a pressure regulating device 700, which is preferably connected to the first container 200 and the second container 300 respectively through the first air inlet valve 210 and the second air inlet valve 310, or connected to the first container 200 and the second container 300 using the above-mentioned three-position four-way valve and other types of valves. The pressure regulating device 700 is also connected to a compressed air source. Preferably, the pressure regulating device 700 is a proportional valve, and can also be other components with a pressure regulating function, or a mechanism, device and assembly with a pressure regulating function.

[0088] To avoid over-adding glaze, Fig.10 As shown, step S101 includes:

[0089] S1011, obtaining the liquid level of the glaze in the first container;

[0090] S1012: When the liquid level of the glaze in the first container rises to a first preset liquid level, the infusion device is closed.

[0091] To avoid printing and transferring glaze, the first container has too little glaze, such as Fig.11 As shown, step S102 includes:

[0092] S1021, obtaining the liquid level of the glaze in the first container;

[0093] S1022. When the liquid level of the glaze in the first container drops to the second preset liquid level, the second air inlet interface, the first exhaust interface and the second exhaust interface are kept closed, and the first air inlet interface is kept open. The pressure of the first container is adjusted by the pressure regulating device, and the infusion device is turned on to input the glaze into the first container.

[0094] It should be noted that the first air inlet valve 210 of the first container is pressure-regulated by the pressure regulating device 700, that is, the glaze spraying device also includes the pressure regulating device 700. The pressure regulating process can be to intake or exhaust air through the first air inlet valve 210, that is, the first air inlet valve 210 can be used for both intake and pressure regulation and exhaust.

[0095] In some embodiments, in order to regulate the gas pressure in the first container 200 and the second container 300, as Fig.12 As shown, the glaze spraying control method also includes:

[0096] S109, when the first air inlet interface and / or the second air inlet interface is opened, the air pressure of the first container and the second container is adjusted according to a preset pressure.

[0097] Specifically, the pressure regulating device 700 regulates the gas pressure of the first container and the second container through the first gas inlet interface and the second gas inlet interface respectively.

[0098] One embodiment of the present invention, as Fig.13 As shown, a glaze spraying controller 100 based on the glaze spraying equipment is also provided. The specific structure of the glaze spraying equipment can refer to the above embodiment and will not be described in detail here.
