[0003] The existing spraying machines for foam glass production have the following problems:

[0004] The existing spraying machines used for foam glass production do not have the ability to spray the deep microporous structure of the foam glass, resulting in a weak adsorption ability of the coating on the substrate after the foam glass is sprayed, affecting the spraying quality of the foam glass. In addition, the traditional spraying machines used for foam glass production do not have the ability to control the spraying depth of the foam glass, thereby reducing the spraying effect of the foam glass.

[0009] Specifically, a controller is provided on the upper wall of the paint cylinder.

[0010] Wherein, the controller is electrically connected to the ultrasonic atomizer, the paint pump, the driving motor, the negative pressure pump and the distance measuring sensor respectively.

[0011] A method for using a spraying machine for producing foam glass, the steps are as follows:

[0012] Step 1: Use the deformation of the clamping spring to place the open-pored foam glass on the bottom wall of the spray tank. The clamping box drives the adsorption valve to fit the two sides of the top of the open-pored foam glass through the elastic rebound force of the clamping spring. The ultrasonic atomizer atomizes the paint inside the paint cylinder into tiny droplets through the power end. The paint pump runs at low power to extract the paint mist inside the paint cylinder. The paint mist is discharged through the spray pipe and diffuses above the open-pored foam glass. The negative pressure pump extracts the air inside the adsorption cylinder. The pressure inside the oblique flow trough is reduced. The sealing plate uses the deformation of the pressure control spring to move relative to each other. The sealing plate enters the oblique flow trough. The outer diameter of the sealing plate is smaller than the inner diameter of the oblique flow trough. A gap for air flow is generated between the oblique flow trough and the sealing plate. The negative pressure pump draws the air inside the open-pored foam glass through the adsorption valve, and the paint mist diffused above the open-pored foam glass enters the open-pored foam glass under the action of the suction of the adsorption valve. The depth of the paint mist entering the open-pored foam glass is consistent with the position of the adsorption valve. Part of the paint is adsorbed on the inner wall of the open-pored foam glass, and the remaining paint mist passes through the open-pored foam glass and flows into the clamping box. The clamping box transports the air containing the paint to the adsorption cylinder. The air containing the paint entering the adsorption cylinder enters the oblique flow trough through the gap between the oblique flow trough and the sealing plate. Under the connection of the series pipe, the excess air containing the paint in the oblique flow trough is discharged through the exhaust end of the negative pressure pump.

[0013] Step 2: After the sealing plate slides along the inner wall of the adsorption tube into the oblique flow channel by means of the deformation of the pressure control spring, the distance between the distance measuring sensor and the sensing block is shortened through the distance measuring end detection. When the internal space of the open-pored foam glass through which the paint mist circulates is filled with paint, the ventilation rate of the open-pored foam glass gradually decreases, and the gas entering the clamping box and the adsorption hose decreases. The pressure control spring elastically resets and drives the sealing plate to slide out of the oblique flow channel. The sealing plates are placed at both ends of the adsorption tube, and the adsorption hose is blocked and cut off, completing the paint filling operation of the internal space of the open-pored foam glass.

[0014] Step 3: When the distance measuring sensor detects that the distance between it and the sensing block is reset, the paint pump runs at high power to extract the paint mist inside the paint cylinder, and the paint mist is quickly sprayed onto the surface of the open-pored foam glass through the spray pipe. Subsequently, the drive motor drives the threaded rod to rotate through the power end, and the threaded rod is engaged with the scraping frame through the thread. The rotation of the threaded rod drives the scraping frame to slide along the inner wall of the scraping groove, and the scraping frame drives the scraping tool to scrape the uneven coating on the surface of the open-pored foam glass, thereby completing the spraying operation of the open-pored foam glass.

[0015] The beneficial effects achieved by adopting the above structure are as follows:

[0016] Compared with existing technologies, this solution combines a negative pressure fixed depth adsorption structure with a pressure-controlled blocking structure, allowing the coating to penetrate into the microporous structure of the open-cell foam glass. The coating forms a mechanical interlocking effect through physical anchoring or chemical bonding, which can significantly improve the adhesion of the coating to the substrate, thereby ensuring the spraying quality of the open-cell foam glass.

[0017] By setting up a flat-smear spraying mechanism and a layer-suction depth control mechanism, with the coordinated use of the bearing component, the atomizing component, the scraping component, the clamping component, the negative suction component and the pressure control component, the adsorption valve is used to extract the air from the top wall of the open-pored foam glass, so that the paint mist diffused above the open-pored foam glass can enter the interior thereof in an orderly manner and fill the micropores therein. When the micropores inside the open-pored foam glass are completely blocked, the pressure control spring resets and drives the sealing plate to cut off the adsorption hose, avoiding the direct negative pressure adsorption of the open-pored foam glass by the negative pressure pump. At the same time, the speed of the paint pump is increased, so that the paint mist can fully spray the surface of the open-pored foam glass, thereby realizing the spraying operation of the inner and outer layers of the open-pored foam glass.

[0039] A controller 37 is provided on the upper wall of the paint cylinder 2 .

[0040] The controller 37 is electrically connected to the ultrasonic atomizer 9 , the paint pump 10 , the drive motor 17 , the negative pressure pump 30 and the distance sensor 35 , respectively.

[0041] A method for using a spraying machine for producing foam glass, the steps are as follows:

[0042] Step 1: Use the deformation of the clamping spring 23 to place the open-pored foam glass on the bottom wall of the spray tank 7. The clamping box 24 drives the adsorption valve 26 to fit the two sides of the top of the open-pored foam glass through the elastic rebound force of the clamping spring 23. The ultrasonic atomizer 9 atomizes the paint inside the paint cylinder 2 into tiny droplets through the power end. The paint pump 10 runs at low power to extract the paint mist inside the paint cylinder 2. The paint mist is discharged through the spray pipe 11 and diffuses above the open-pored foam glass. The negative pressure pump 30 extracts the air inside the adsorption cylinder 27. The pressure inside the oblique flow groove 33 is reduced. The sealing plate 34 uses the deformation of the pressure control spring 32 to move relative to each other. The sealing plate 34 enters the oblique flow groove 33. The outer diameter of the sealing plate 34 is smaller than the inner diameter of the oblique flow groove 33. An air flow is generated between the oblique flow groove 33 and the sealing plate 34. The flow spacing allows the negative pressure pump 30 to extract the air inside the open-pored foam glass through the adsorption valve 26, and the paint mist diffused above the open-pored foam glass enters the open-pored foam glass under the action of the suction force of the adsorption valve 26. The depth of the paint mist entering the open-pored foam glass is consistent with the position of the adsorption valve 26. Part of the paint is adsorbed on the inner wall of the open-pored foam glass, and the remaining paint mist passes through the open-pored foam glass and flows into the clamping box 24. The clamping box 24 transports the air containing the paint to the adsorption cylinder 27. The air containing the paint entering the adsorption cylinder 27 enters the oblique flow groove 33 through the spacing between the oblique flow groove 33 and the sealing plate 34. Under the connection of the serial pipe 29, the excess air containing the paint in the oblique flow groove 33 is discharged through the exhaust end of the negative pressure pump 30.

[0043] Step 2: After the sealing plate 34 is deformed by the pressure control spring 32 and slides along the inner wall of the adsorption cylinder 27 into the interior of the oblique flow groove 33, the distance between the distance sensor 35 and the sensing block 36 is shortened through the distance detection end. When the internal space of the open-pore foam glass through which the paint mist circulates is filled with paint, the ventilation rate of the open-pore foam glass gradually decreases, and the gas entering the clamping box 24 and the adsorption hose 28 decreases. The pressure control spring 32 elastically resets and drives the sealing plate 34 to slide out of the oblique flow groove 33. The sealing plate 34 is placed at both ends of the adsorption cylinder 27, and the adsorption hose 28 is blocked and cut off, completing the paint filling operation of the internal space of the open-pore foam glass;

[0044] Step 3: When the distance measuring sensor 35 detects that the distance between it and the sensing block 36 is reset, the paint pump 10 runs at high power to extract the paint mist inside the paint tube 2, and the paint mist is quickly sprayed onto the surface of the open-pored foam glass through the spray pipe 11. Subsequently, the drive motor 17 drives the threaded rod 14 to rotate through the power end, and the threaded rod 14 is engaged with the scraping frame 15 through a thread. The rotation of the threaded rod 14 drives the scraping frame 15 to slide along the inner wall of the scraping groove 13, and the scraping frame 15 drives the scraping tool 16 to scrape the uneven coating on the surface of the open-pored foam glass, thereby completing the spraying operation on the open-pored foam glass.

[0045] During specific use, the paint to be sprayed is injected into the paint barrel 2, the clamping spring 23 is normally set to an extended setting, the pressure control spring 32 is normally set to a shortened setting, the adsorption hose 28 and the oblique flow groove 33 are in a cut-off state, the controller 37 controls the distance sensor 35 to start, the distance sensor 35 detects the distance between the distance measuring end and the sensing block 36, and pulls the limit block 22. The limit block 22 uses the deformation of the clamping spring 23 to drive the guide column 21 to slide along the inner wall of the clamping sleeve 20. The guide column 21 drives the clamping box 24 and the adsorption valve 26 to move in opposite directions, and the distance between the clamping boxes 24 increases;

[0046] The open-pored foam glass is placed on the bottom wall of the spray tank 7, and the two sides of the open-pored foam glass are respectively fitted with the inner walls of the two ends of the spray tank 7, the limit block 22 is loosened, and the clamping box 24 uses the reset elastic force of the clamping spring 23 to drive the adsorption valve 26 to fit with the two sides of the top of the open-pored foam glass, and the controller 37 controls the ultrasonic atomizer 9 to start, and the ultrasonic atomizer 9 atomizes the paint inside the paint barrel 2 into tiny droplets through the power end, and the controller 37 controls the paint pump 10 to start, and the paint pump 10 runs at low power to extract the paint mist inside the paint barrel 2, and the paint mist is discharged at a slower speed through the spray pipe 11 and diffused above the open-pored foam glass;

[0047] The controller 37 controls the negative pressure pump 30 to start, and the negative pressure pump 30 extracts the air inside the adsorption cylinder 27 and the oblique flow groove 33. The pressure inside the adsorption cylinder 27 and the oblique flow groove 33 is reduced, and the sealing plate 34 uses the deformation of the pressure control spring 32 to move relative to each other. The sealing plate 34 slides along the inner wall of the adsorption cylinder 27 and enters the oblique flow groove 33. Since the outer diameter of the sealing plate 34 is smaller than the inner diameter of the oblique flow groove 33, an air flow gap is generated between the oblique flow groove 33 and the sealing plate 34. The negative pressure pump 30 extracts the air inside the open-pore foam glass through the adsorption valve 26, and the paint mist diffused above the open-pore foam glass is sucked by the adsorption valve 26. The paint mist enters the open-pored foam glass, and the depth of the paint mist entering the open-pored foam glass is consistent with the position of the adsorption valve 26. Part of the paint is adsorbed inside the microporous structure of the open-pored foam glass, and the remaining paint mist passes through the open-pored foam glass and flows into the clamping box 24. The clamping box 24 transports the paint-containing air to the adsorption cylinder 27. The paint-containing air entering the adsorption cylinder 27 flows into the oblique flow groove 33 through the gap between the oblique flow groove 33 and the sealing plate 34. Under the connection of the serial pipe 29, the excess paint-containing air in the oblique flow groove 33 is discharged through the exhaust end of the negative pressure pump 30.

[0048] After the sealing plate 34 is deformed by the pressure control spring 32 and slides along the inner wall of the adsorption cylinder 27 into the interior of the oblique flow groove 33, the distance between the distance measuring sensor 35 and the sensing block 36 is shortened through the distance measuring end detection. After the microporous structure inside the open-pore foam glass is filled with paint, the air permeability of the open-pore foam glass gradually decreases, and the gas entering the clamping box 24 and the adsorption hose 28 through the open-pore foam glass decreases. The pressure control spring 32 elastically resets and drives the sealing plate 34 to slide toward the two ends of the oblique flow groove 33. The distance between the inner diameter of the oblique flow groove 33 and the outer diameter of the sealing plate 34 is shortened, completing the spraying operation on the microporous structure inside the open-pore foam glass.

[0049] When the power end of the distance measuring sensor 35 detects that the distance between it and the induction block 36 is within the distance range specified by the operator, the controller 37 controls the paint pump 10 to operate at high power to extract the paint mist inside the paint cylinder 2, and the paint mist is sprayed onto the surface of the open-pore foam glass at a relatively fast speed through the spray pipe 11;

[0050] After high-speed spraying on the surface of the open-pored foam glass, the limit block 22 is pulled through the guide column 21 to drive the clamping box 24 away from the side wall of the open-pored foam glass. The side of the open-pored foam glass away from the spraying frame 3 is blocked by a baffle. The controller 37 controls the drive motor 17 to start. The drive motor 17 drives the threaded rod 14 to rotate through the power end. The threaded rod 14 is engaged with the scraping frame 15 through a thread. The rotation of the threaded rod 14 drives the scraping frame 15 to slide along the inner wall of the scraping groove 13. The scraping frame 15 drives the scraping tool 16 to scrape the uneven coating on the surface of the open-pored foam glass, thereby completing the spraying operation on the open-pored foam glass. Repeat the above operation when using it next time.

2. The method for using a spraying machine for producing foam glass according to claim 1, characterized in that: The paint mist is then drawn into the paint tank by the suction valve, and the pressure inside the paint tank is reduced by the suction valve. Step 2: After the sealing plate slides along the inner wall of the adsorption tube and enters the oblique flow channel by means of the deformation of the pressure control spring, the distance between the distance measuring sensor and the sensing block is shortened through the distance measuring end detection. When the internal space of the open-pore foam glass through which the paint mist circulates is filled with paint, the ventilation rate of the open-pore foam glass gradually decreases, and the gas entering the clamping box and the adsorption hose decreases. The pressure control spring elastically resets and drives the sealing plate to slide out of the oblique flow channel. The sealing plates are placed at both ends of the adsorption tube, and the adsorption hose is blocked and cut off. Step 3: After the distance measuring sensor detects the distance between it and the sensing block and resets, the paint pump runs at high power to extract the paint mist inside the paint cylinder, and the paint mist is quickly sprayed onto the surface of the open-pored foam glass through the spray pipe. Subsequently, the drive motor drives the threaded rod to rotate through the power end, and the threaded rod is engaged with the scraping frame through the thread. The rotation of the threaded rod drives the scraping frame to slide along the inner wall of the scraping groove, and the scraping frame drives the scraping tool to scrape the uneven coating on the surface of the open-pored foam glass.
