It has the characteristics of fire prevention, waterproofing, non-toxicity, corrosion resistance, mothproofing, non-aging, no radioactivity, insulation, electromagnetic wave prevention, anti-static, high mechanical strength, and good adhesion to various slurries. The spraying process in foam glass production is a key process in product manufacturing, directly affecting its heat insulation performance, waterproof performance, and surface quality.

[0003] Currently, the existing spraying machines for foam glass production have the following problems: The existing spraying machines for foam glass production do not have the ability to spray the deep microporous structure of foam glass, resulting in a weak adsorption capacity of the coating on the substrate after spraying foam glass, affecting the spraying quality of foam glass. Moreover, the traditional spraying machines for foam glass production also do not have the ability to control the spraying depth of foam glass, thereby reducing the spraying effect on foam glass. Therefore, they cannot meet the current usage requirements for spraying machines in foam glass production. Summary of the Invention

The pressure control assembly includes a pressure control spring, an inclined flow groove, a sealing plate, a distance measuring sensor and an induction block.

The distance measuring sensor is arranged on the side wall of the sealing plate at one end of the adsorption cylinder, and the induction block is arranged on the side wall of the sealing plate at the end of the adsorption cylinder away from the induction block.

[0008] Specifically, a controller is arranged on the upper wall of the paint cylinder.

[0009] Among them, 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.

[0010] A using method of a spraying machine for foam glass production is as follows: Step 1: Use the deformation of the clamping spring to place the open-cell foam glass on the bottom wall of the spraying tank. The clamping box drives the adsorption valve to fit with both sides of the top of the open-cell foam glass through the elastic restoring 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 operates at a low power to extract the paint mist inside the paint cylinder. After the paint mist is discharged through the spraying pipe, it diffuses above the open-cell foam glass. The negative pressure pump extracts the air inside the adsorption cylinder, the pressure inside the inclined flow groove decreases, and the sealing plate moves relative to each other using the deformation of the pressure control spring. The sealing plate enters the inclined flow groove. The outer diameter of the sealing plate is smaller than the inner diameter of the inclined flow groove, and a spacing for air flow is generated between the inclined flow groove and the sealing plate, enabling the negative pressure pump to extract the air inside the open-cell foam glass through the adsorption valve. The paint mist diffused above the open-cell foam glass enters the open-cell foam glass under the action of the suction force of the adsorption valve. The depth of the paint mist entering the open-cell foam glass is the same as the position of the adsorption valve. Part of the paint is adsorbed on the inner wall of the open-cell foam glass, and the remaining paint mist flows through the open-cell foam glass and into the clamping box. The clamping box transports the air containing paint to the inside of the adsorption cylinder. The air containing paint entering the adsorption cylinder enters the inclined flow groove through the spacing between the inclined flow groove and the sealing plate. Under the connection of the series connection pipe, the excess air containing paint inside the inclined flow groove is discharged through the exhaust end of the negative pressure pump.

[0011] Step 2: After the sealing plate slides into the inclined flow groove along the inner wall of the adsorption cylinder using the deformation of the pressure control spring, the distance measuring sensor detects a shortening of the distance from the distance measuring end to the induction block. When the internal space of the open-cell foam glass through which the paint mist flows is filled with paint, the air permeability of the open-cell foam glass gradually decreases, and the gas entering the clamping box and the adsorption hose decreases. The elastic reset of the pressure control spring drives the sealing plate to slide out of the inclined flow groove. The sealing plate is placed at both ends of the adsorption cylinder, and the adsorption hose is blocked and cut off, completing the paint filling operation for the internal space of the open-cell foam glass. Step 3: When the distance measuring sensor detects that the distance to the induction block is reset, the paint pump operates at a high power to extract the paint mist inside the paint cylinder. The paint mist is quickly sprayed onto the surface of the open-cell foam glass through the spraying pipe. Subsequently, the drive motor drives the threaded rod to rotate through the power end. The threaded rod is meshed 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. The scraping frame drives the scraping tool to scrape the uneven coating on the surface of the open-cell foam glass, thereby completing the spraying operation for the open-cell foam glass.

[0012] The beneficial effects obtained by this solution using the above structure are as follows: Compared with the prior art, the present solution combines a negative-pressure depth-fixed adsorption structure with a pressure-control blocking structure, enabling the coating to penetrate into the microporous structure of the open-cell foam glass. Through physical anchoring or chemical bonding among the coatings, a mechanical interlocking effect is formed, which can significantly improve the adhesion of the coating to the substrate, thereby ensuring the spraying quality of the open-cell foam glass. Through the arranged flat-spreading spraying mechanism and layer-suction depth-control mechanism, under the coordinated use of the bearing component, atomization component, scraping component, clamping component, negative-suction component and pressure-control component, the air on the top wall of the open-cell foam glass is extracted by the adsorption valve, enabling the coating mist diffused above the open-cell foam glass to enter its interior orderly and fill the micropores inside. When the micropores inside the open-cell foam glass are completely blocked, the pressure-control spring resets to drive the sealing plate to cut off the adsorption hose, preventing the negative-pressure pump from directly performing negative-pressure adsorption on the open-cell foam glass. Meanwhile, the rotational speed of the coating pump increases, enabling the coating mist to fully spray the surface of the open-cell foam glass, realizing the spraying operation on both the inner and outer layers of the open-cell foam glass.

[0021] A controller 37 is arranged on the upper wall of the paint cylinder 2.

[0022] 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 measuring sensor 35 respectively.

[0023] A method for using a spraying machine for foam glass production is as follows: Step 1: Utilize the deformation of the clamping spring 23 to place the open-cell foam glass on the bottom wall of the spraying tank 7. The clamping box 24 drives the adsorption valve 26 to fit against both sides of the top of the open-cell foam glass through the elastic restoring 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 operates at low power to extract the paint mist inside the paint cylinder 2. The paint mist diffuses above the open-cell foam glass after being discharged through the spraying pipe 11. The negative pressure pump 30 extracts the air inside the adsorption cylinder 27, reducing the pressure inside the inclined flow channel 33. The sealing plate 34 moves relatively through the deformation of the pressure control spring 32 and enters the inclined flow channel 33. The outer diameter of the sealing plate 34 is smaller than the inner diameter of the inclined flow channel 33, creating a spacing for air flow between the inclined flow channel 33 and the sealing plate 34. This enables the negative pressure pump 30 to extract the air inside the open-cell foam glass through the adsorption valve 26. The paint mist diffused above the open-cell foam glass enters the open-cell foam glass under the action of the suction force of the adsorption valve 26. The depth at which the paint mist enters the open-cell 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-cell foam glass, and the remaining paint mist flows through the open-cell foam glass and into the clamping box 24 after passing through. The clamping box 24 conveys the air containing paint into the adsorption cylinder 27. The air containing paint that enters the adsorption cylinder 27 enters the inclined flow channel 33 through the spacing between the inclined flow channel 33 and the sealing plate 34. Through the connection of the connecting pipe 29, the excess air containing paint inside the inclined flow channel 33 is discharged through the exhaust end of the negative pressure pump 30.

[0024] Step 2: After the sealing plate 34 slides into the inclined flow channel 33 along the inner wall of the adsorption cylinder 27 by utilizing the deformation of the pressure control spring 32, the distance measuring sensor 35 detects a shortening of the distance from its distance measuring end to the induction block 36. When the internal space of the open-cell foam glass through which the paint mist flows is filled with paint, the air permeability of the open-cell foam glass gradually decreases, and the gas entering the clamping box 24 and the adsorption hose 28 decreases. The elastic reset of the pressure control spring 32 drives the sealing plate 34 to slide out of the inclined flow channel 33. The sealing plate 34 is placed at both ends of the adsorption cylinder 27, blocking and cutting off the adsorption hose 28, thus completing the paint filling operation for the internal space of the open-cell foam glass. Step 3: When the distance measuring sensor 35 detects that the distance to the induction block 36 is reset, the paint pump 10 operates at high power to extract the paint mist inside the paint cylinder 2. The paint mist is quickly sprayed onto the surface of the open-cell foam glass through the spraying pipe 11. Subsequently, the driving motor 17 drives the threaded rod 14 to rotate through the power end. The threaded rod 14 is threadedly engaged with the scraping frame 15. 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-cell foam glass, thereby completing the spraying operation for the open-cell foam glass.

[0025] During specific use, paint to be sprayed is injected into the interior of the paint cylinder 2. The clamping spring 23 is set to be in an extended state under normal conditions, and the pressure control spring 32 is set to be in a compressed state under normal conditions. The adsorption hose 28 and the inclined flow channel 33 are in a cut-off state. The controller 37 controls the distance measuring sensor 35 to start. The distance measuring sensor 35 detects the distance from its distance measuring end to the induction block 36, pulling the limit block 22. The limit block 22 drives the guide post 21 to slide along the inner wall of the clamping sleeve 20 by deforming the clamping spring 23. The guide post 21 drives the clamping box 24 and the adsorption valve 26 to move away from each other, increasing the distance between the clamping boxes 24; Place the open-cell foam glass on the bottom wall of the spraying tank 7. The two sides of the open-cell foam glass are respectively attached to the inner walls at both ends of the spraying tank 7. Release the limit block 22. The clamping box 24 drives the adsorption valve 26 to be attached to both sides of the top of the open-cell foam glass by the restoring elastic force of the clamping spring 23. The controller 37 controls the ultrasonic atomizer 9 to start. The ultrasonic atomizer 9 atomizes the paint inside the paint cylinder 2 into tiny droplets through its power end. The controller 37 controls the paint pump 10 to start. The paint pump 10 operates at a low power to extract the paint mist inside the paint cylinder 2. The paint mist diffuses above the open-cell foam glass after being discharged through the spraying pipe 11 at a slower speed; The controller 37 controls the negative pressure pump 30 to start. The negative pressure pump 30 extracts the air inside the adsorption cylinder 27 and the inclined flow channel 33, reducing the pressure inside the adsorption cylinder 27 and the inclined flow channel 33. The sealing plate 34 moves relative to each other by deforming the pressure control spring 32. The sealing plate 34 slides along the inner wall of the adsorption cylinder 27 and enters the inclined flow channel 33. Since the outer diameter of the sealing plate 34 is smaller than the inner diameter of the inclined flow channel 33, an air flow gap is generated between the inclined flow channel 33 and the sealing plate 34. The negative pressure pump 30 extracts the air inside the open-cell foam glass through the adsorption valve 26. The paint mist diffused above the open-cell foam glass enters the open-cell foam glass under the action of the suction force of the adsorption valve 26. The depth of the paint mist entering the open-cell 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-cell foam glass, and the remaining paint mist flows into the clamping box 24 after passing through the open-cell foam glass. The clamping box 24 conveys the air containing paint into the adsorption cylinder 27. The air containing paint entering the adsorption cylinder 27 flows into the inclined flow channel 33 through the gap between the inclined flow channel 33 and the sealing plate 34. Under the connection of the connecting pipe 29, the excess air containing paint inside the inclined flow channel 33 is discharged through the exhaust end of the negative pressure pump 30; After the sealing plate 34 slides into the internal oblique flow channel 33 along the inner wall of the adsorption cylinder 27 by the deformation of the pressure control spring 32, the distance measuring sensor 35 detects that the distance between it and the induction block 36 shortens through the distance measuring end. After the microporous structure inside the open-cell foam glass is filled with the coating material, the air permeability of the open-cell foam glass gradually decreases, and the gas entering the clamping box 24 and the adsorption hose 28 through the open-cell foam glass decreases. The elastic reset of the pressure control spring 32 drives the sealing plate 34 to slide towards both ends of the oblique flow channel 33, and the distance between the inner diameter of the oblique flow channel 33 and the outer diameter of the sealing plate 34 decreases, completing the spraying operation on the microporous structure inside the open-cell foam glass; 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 sprays onto the surface of the open-cell foam glass at a relatively fast speed through the spraying pipe 11; After the high-speed spraying on the surface of the open-cell foam glass, the limiting block 22 is pulled to drive the clamping box 24 away from the side wall of the open-cell foam glass through the guiding column 21. The side of the open-cell foam glass away from the spraying frame 3 is blocked by the baffle. The controller 37 controls the driving motor 17 to start, and the driving motor 17 drives the threaded rod 14 to rotate through the power end. The threaded rod 14 and the leveling frame 15 are engaged by threads. The rotation of the threaded rod 14 drives the leveling frame 15 to slide along the inner wall of the leveling groove 13, and the leveling frame 15 drives the leveling cutter 16 to level the uneven coating on the surface of the open-cell foam glass, thereby completing the spraying operation on the open-cell foam glass; Just repeat the above operations when using it next time.

7. The usage method of a spraying machine for foam glass production according to claim 6, wherein: Step 1: Place the perforated foam glass on the bottom wall of the spraying tank by utilizing the deformation of the clamping spring. The clamping box drives the adsorption valve to fit with both sides of the top of the perforated foam glass through the elastic resilience of the clamping spring. The ultrasonic atomizer atomizes the paint inside the paint cylinder into tiny droplets through the power end. The paint pump operates at a low power to extract the paint mist inside the paint cylinder. The paint mist diffuses above the perforated foam glass after being discharged through the spraying pipe. The negative pressure pump extracts the air inside the adsorption cylinder, the pressure inside the inclined flow channel decreases, the sealing plate moves relatively by utilizing the deformation of the pressure control spring, and the sealing plate enters the inclined flow channel. The outer diameter of the sealing plate is smaller than the inner diameter of the inclined flow channel, and a spacing for air flow is generated between the inclined flow channel and the sealing plate, so that the negative pressure pump extracts the air inside the perforated foam glass through the adsorption valve. The paint mist diffused above the perforated foam glass enters the perforated foam glass under the action of the suction force of the adsorption valve, and the depth of the paint mist entering the perforated foam glass is the same as the position where the adsorption valve is located. Step 2: After the sealing plate slides into the inclined flow channel along the inner wall of the adsorption cylinder by utilizing the deformation of the pressure control spring, the distance measuring sensor detects that the distance from the induction block is shortened through the distance measuring end. When the internal space of the perforated foam glass through which the paint mist flows is filled with paint, the air permeability of the perforated foam glass gradually decreases, and the gas entering the clamping box and the adsorption hose decreases. The pressure control spring elastically resets to drive the sealing plate to slide out of the inclined flow channel, and the sealing plate is placed at both ends of the adsorption cylinder, blocking and cutting off the adsorption hose. Step 3: After the distance measuring sensor detects that the distance from the induction block is reset, the paint pump operates at a high power to extract the paint mist inside the paint cylinder. The paint mist is quickly sprayed onto the surface of the perforated foam glass through the spraying pipe. Subsequently, the driving motor drives the threaded rod to rotate through the power end. The threaded rod is meshed with the scraping frame through threads, and the rotation of the threaded rod drives the scraping frame to slide along the inner wall of the scraping groove. The scraping frame drives the scraping tool to scrape the uneven coating on the surface of the perforated foam glass.
