Description

Technical Field

[0001] The present invention relates to the field of building formwork production, and more specifically to a spraying device for the surface of building formwork. Background Art

[0002] In the construction industry, the treatment of the formwork surface is crucial for ensuring the quality of concrete structures. Traditional formwork surface treatment methods usually include manual cleaning and spraying. These processes are not only time-consuming and laborious but also difficult to ensure the consistency and aesthetics of the coating. With the rapid development of the construction industry, the requirements for formwork surface treatment efficiency and quality are getting higher and higher, which has promoted the development of automated formwork surface treatment equipment. However, existing technologies often have problems such as single function, low automation level, and inability to effectively handle waste gas and waste liquid, resulting in low production efficiency and potential environmental pollution.

[0003] A Chinese patent with the application number 202210267183.8 discloses a spraying device for the surface of building formwork, including a support plate, with a support plate provided on the top of the base; a support frame, with support frames provided on both the front and back sides of the support plate; spraying cans, with three spraying cans evenly spaced on the upper and lower sides of both support frames, and a total of twelve spraying cans; and stretching spray pipes, with stretching spray pipes slidably provided on the tops of the six upper spraying cans. By driving the first connecting rod to move inward through a push rod, during the inward movement of the first connecting rod, the top rod is driven to move upward, the top rod drives the second connecting rod to move upward, the second connecting rod drives the friction plate to move upward, and the friction plate pushes the formwork to move upward, so as to assist the formwork to move upward and facilitate the application of paint to the side of the formwork.

[0004] A Chinese patent with the application number 202322383575.3 discloses a spraying device for the surface of building formwork, including a base, with a paint spraying frame installed on the top of the base, a paint tank installed on the top of the paint spraying frame, a connecting pipe installed on the relatively narrow side surface of the periphery of the paint tank, a paint pump sleeved on the outer wall of the connecting pipe, a connecting frame installed inside the paint spraying frame, a paint spraying rod installed on the connecting frame, and a spray head fixedly installed at the outer end of the paint spraying rod. A control panel is embedded and installed on the relatively long side surface of the periphery of the paint spraying frame. In the present utility model, by providing a spraying device for the surface of building formwork, with the drying rack, drying lamp, rolling wheels, rotating belt, and rotating motor of the device, the device can dry the building formwork, thereby being able to accelerate the drying speed, greatly reducing time and labor costs, and completely avoiding situations such as touching after not being dried.

[0005] However, the following problems still exist in actual applications, specifically:

[0006] 1. These two patents mainly focus on the improvement of the spraying process, while ignoring other important links in the entire formwork treatment process, restricting the improvement of the overall working efficiency.

[0007] 2. Due to the incomplete integration of functional modules, the devices described in these two patents require a lot of manual intervention during actual operation, especially in aspects such as the clamping of templates, surface cleaning, and post-spraying treatment.

[0052] The building formwork surface spraying device of the present invention will be described in more detail below with reference to the accompanying drawings and through specific implementation manners.

[0053] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0054] See Figures 1 - 8, A surface spraying device for building templates in this embodiment integrates multiple functional modules such as template conveying, cleaning, spraying, smearing, and waste recycling. These modules work together, greatly improving production efficiency, reducing the need for manual intervention, and can also clean the template surface before spraying, further evenly distributing the coating after spraying to ensure the consistency and aesthetics of the coating. At the same time, it can collect and process the waste gas and waste liquid generated during the spraying process to reduce environmental pollution. In this embodiment, it mainly includes a spray chamber 1 with adjustable height. The spray chamber 1 is a U-shaped structure with an opening facing downwards. At the bottom of the outer sides of both ends of the spray chamber 1, fixed frames 8 are vertically and fixedly arranged. A support frame 9 is slidably arranged at the bottom end of the fixed frame 8. Both the fixed frame 8 and the support frame 9 are H-shaped structures. A lead screw 10 is vertically and threadedly arranged in the middle of the support frame 9. The top end of the lead screw 10 is rotatably arranged at the middle position of the fixed frame 8. By rotating the corresponding lead screw 10, the fixed frame 8 can move up and down on the support frame 9, thereby driving the spray chamber 1 to move up and down to achieve adjustable height of the spray chamber 1 and adapt to operations at different heights.

[0055] To achieve the conveyance of the template, refer to Figures 1 - 4 , In this embodiment, template conveying mechanisms 2 are arranged at both the inlet and outlet of the spray chamber 1. The template conveying mechanism 2 includes a conveying roller 21 horizontally and rotatably arranged above the opening of the spray chamber 1. A first motor 22 for driving the rotation of the conveying roller 21 is fixedly arranged on the outer wall of the spray chamber 1. At least two vertical chutes 23 are opened on the outer walls of both ends of the spray chamber 1. A moving shaft 24 is horizontally arranged below the conveying roller 21. Both ends of the moving shaft 24 slide in the corresponding chutes 23. A rotating roller 25 is sleeved on the moving shaft 24. Moving blocks 26 are fixedly arranged at both ends of the moving shaft 24. Fixed blocks 27 are fixedly arranged on the side wall of the spray chamber 1 below the moving blocks 26. A spring 28 is fixedly arranged between the top end of the fixed block 27 and the bottom end of the moving block 26. Control the first motor 22 to work and drive the conveying roller 21 to rotate. When the template enters the spray chamber 1 between the conveying roller 21 and the rotating roller 25, the rotating roller 25 presses the moving block 26 downwards, causing the moving block 26 to move downwards in the chute 23 against the resistance of the spring 28. The rotating roller 25 is always in contact with the bottom end of the template through the spring 28. The template moves towards the inside of the spray chamber 1 under the action of the conveying pipe.

[0056] To achieve the leveling of the upper surface of the template, in this embodiment, refer to Figures 1 - 5, a leveling unit 3 for cleaning the upper surface of the plate is horizontally arranged inside the inlet of the spraying chamber 1. The leveling unit 3 includes a first baffle 301 and a second baffle 302 vertically and fixedly arranged above the opening of the spraying chamber 1. A cleaning chamber 303 is formed between the first baffle 301 and the second baffle 302. A first support 304 is fixedly arranged inside the cleaning chamber 303 at the opening of the spraying chamber 1. The first support 304 is an L-shaped structure with the vertical end facing downwards. A friction roller 305 that can abut against the upper surface of the template is horizontally rotatably arranged inside the spraying chamber 1 between the first baffle 301 and the first support 304. A second motor 306 for driving the friction roller 305 to rotate is fixedly arranged on the outer wall of the spraying chamber 1. A scraper 307 is vertically and fixedly arranged at the bottom end of the first support 304. The scraping part of the scraper 307 faces the direction of the friction roller 305 and its bottom end can abut against the upper surface of the template. A second support 308 is fixedly arranged at the rear side of the first support 304. The second support 308 is an L-shaped structure with the vertical end facing downwards. A cleaning brush 309 is fixedly arranged at the bottom end of the second support 308.

[0057] Control the second motor 306 to work, drive the friction roller 305 to rotate, and the friction between the friction roller 305 and the upper surface of the template erases larger protrusions and burrs. The template continues to move, and the remaining burrs on the upper surface of the template are scraped off by the scraper 307, thereby ensuring the flatness of the template surface and improving the quality of subsequent spraying. The template continues to move, and the impurities removed by friction and scraping are left in the cleaning chamber 303 by the cleaning brush 309.

[0058] Spray holes 310 are formed at both ends of the spraying chamber 1. The spray holes 310 are located at the lower part between the first baffle 301 and the second baffle 302. An air box 311 is fixedly arranged on the outer wall of the spraying chamber 1. An air compressor pump 312 is fixedly connected and arranged at the top end of the air box 311. The air compressor pump 312 is a mature prior art and will not be described in detail here. The air box 311 abuts against the corresponding spray hole 310. Two sets of main pipes 313 are fixedly arranged at the top end of the spraying chamber 1. The end of the main pipe 313 abuts against the air box 311. A plurality of branch pipes 314 are vertically communicated and arranged at the bottom end of the main pipe 313. The bottom ends of the branch pipes 314 penetrate through the first support 304 and the second support 308 and are respectively located above the friction roller 305 and between the first support 304 and the second support 308. The air outlets of the branch pipes 314 all face the position of the spray hole 310 on the opposite side of the air box 311.

[0059] Control the operation of the air compression pump 312. At this time, the air is pressurized and then discharged into the air box 311, causing the air to be divided into two paths. One path enters the main pipe 313 and then enters the branch pipe 314, and is sprayed downward from the bottom of the branch pipe 314 in the cleaning chamber 303. The other path enters directly through the spray holes 310 and blows directly towards the other spray holes 310. Under the action of the impact of the two paths of air, the impurities in the cleaning chamber 303 are ejected from the spray holes 310, and the surface of the template is cleaned by air. This avoids impurities from affecting the spraying effect and improves the overall work efficiency at the same time.

[0060] To achieve spraying on the upper surface of the template, specifically refer to Figures 1 - 8 , inside the spraying chamber 1 behind the leveling unit 3, a spraying module 4 located above the plate is horizontally arranged. The spraying module 4 includes a spraying material unit 5 arranged behind the leveling unit 3. The spraying material unit 5 includes at least one position sensor 501 fixedly arranged in the cleaning chamber 303 in front of the second baffle 302. Inside the spraying chamber 1 behind the second baffle 302, a third baffle 502 is vertically fixedly arranged. A spraying chamber 503 is formed between the second baffle 302 and the third baffle 502. At the top of the spraying chamber 1, a liquid storage tank 504 is fixedly arranged. At the bottom of the side of the liquid storage tank 504, at least one liquid extraction pump 505 is fixedly arranged. The liquid outlet of the liquid extraction pump 505 is connected to a liquid outlet pipe 506. The other end of the liquid outlet pipe 506 penetrates the top wall of the spraying chamber 1 and extends into the interior of the spraying chamber 503. Inside the spraying chamber 503 behind the second baffle 302, at least one distribution box 507 is fixedly arranged. The bottom of the distribution box 507 is connected to a plurality of spray pipes 508. The bottom of the spray pipe 508 is connected to a nozzle 509.

[0061] Add spraying liquid into the liquid storage tank 504. When the template is detected by the position sensor 501, control the liquid extraction pump 505 to work, pump the liquid in the liquid storage tank 504 towards the liquid outlet pipe 506, and discharge it into the distribution box 507 through the liquid outlet pipe 506. At this time, the liquid is evenly sprayed onto the upper surface of the template through the spray pipes 508 and nozzles, completely covering the entire upper surface.

[0062] Inside the spraying chamber 1 at the rear side of the spraying material unit 5, a smearing unit 6 is provided. The smearing unit 6 includes a smearing roller 601 horizontally rotatably arranged inside the spraying chamber 503 at the rear side of the distribution box 507. A soft cloth 602 is sleeved on the smearing roller 601, and the soft cloth 602 can be abutted against the upper surface of the template. A third motor 603 for driving the smearing roller 601 to rotate is fixedly arranged on the outer wall of the spraying chamber 1. A scraping plate 604 is horizontally fixedly arranged in the spraying chamber 503 on the side of the smearing roller 601, and the scraping plate 604 abuts against the soft cloth 602 in the upper middle part of the smearing roller 601. A liquid collecting plate 605 is fixedly arranged inside the spraying chamber 503 below the scraping plate 604. The liquid collecting plate 605 is in a U-shaped structure with one end high, one end low and the opening upward. A liquid collecting box 606 is fixedly arranged on the outer wall of the spraying chamber 1, and the lowest end of the liquid collecting plate 605 extends into the inside of the liquid collecting box 606.

[0063] Control the third motor 603 to work, drive the smearing roller 601 to rotate. At this time, the soft cloth 602 abuts against the upper surface of the template, so as to wipe the upper surface of the template sprayed with liquid. Thus, the paint on the upper surface of the template is further evenly distributed, ensuring the consistency and beauty of the coating. During this process, the paint accumulated on the soft cloth 602 is scraped off by the scraping plate 604, so that the paint drops onto the liquid collecting plate 605, and the paint is collected into the inside of the liquid collecting box 606 through the inclined liquid collecting plate 605 for recycling, which is convenient for subsequent reuse or discarding.

[0064] A waste material recycling unit 7 is arranged at the top end of the spraying chamber 1. The waste material recycling unit 7 includes a processing box 701 fixedly arranged at the top end of the spraying chamber 1. A plurality of filter plates 702 are horizontally fixedly arranged in the upper part of the inside of the processing box 701. An exhaust pipe 703 is opened at the top end of the processing box 701 above the filter plates 702, and an exhaust fan 704 with a motor is fixedly arranged inside the exhaust pipe 703. The bottom end inside the processing box 701 is an inclined surface, and a liquid discharge pipe 705 is opened on the side wall of the processing box 701 at the lowest end of the inclined surface. A gas collecting pipe 706 is communicated with the side part of the processing box 701 below the filter plates 702, and the other end of the gas collecting pipe 706 penetrates through the spraying chamber 503 and a gas collecting hood 707 is horizontally fixedly arranged at the end of the other end of the gas collecting pipe 706.

[0065] Control the exhaust fan 704 to work through the motor, so as to form a negative pressure inside the processing box 701, and then collect the mist generated in the spraying chamber 503 into the inside of the processing box 701 through the gas collecting hood 707 and the gas collecting pipe 706. At this time, the mist is filtered by the filter plates 702 and the gas is discharged from the exhaust fan 704 to avoid environmental pollution. The liquid drops to the bottom of the processing box 701, and the liquid is discharged from the liquid discharge pipe 705 through the inclined bottom surface for liquid recycling.

[0066] Usage method of the spraying device for the surface of the building formwork of the present invention: First, rotate the corresponding lead screw 10 to move the fixed frame 8 up and down on the support frame 9, thereby driving the spraying chamber 1 to move up and down, so as to realize the adjustable height of the spraying chamber 1 and adapt to operations at different heights.

[0067] Control the first motor 22 to work and drive the conveying roller 21 to rotate. When the formwork enters the spraying chamber 1 between the conveying roller 21 and the rotating roller 25, the rotating roller 25 presses the moving block 26 downward, so that the moving block 26 moves downward in the chute 23 against the resistance of the spring 28, and the rotating roller 25 is always in contact with the bottom end of the formwork through the spring 28. The formwork moves into the interior of the spraying chamber 1 under the action of the conveying pipe.

[0068] Control the second motor 306 to work and drive the friction roller 305 to rotate. The friction roller 305 generates friction with the upper surface of the formwork to wipe off larger protrusions and burrs. The formwork continues to move, and the remaining burrs on the upper surface of the formwork are scraped off by the scraper 307, so as to ensure the flatness of the formwork surface and improve the quality of subsequent spraying. The formwork continues to move, and the impurities wiped off by friction and scraping are left in the cleaning chamber 303 by the cleaning brush 309. Control the air compression pump 312 to work. At this time, the air is pressurized and then discharged into the air box 311. Thus, the air is divided into two paths. One path enters the main pipe 313 and then enters the branch pipe 314, and is sprayed downward from the bottom end of the branch pipe 314 in the cleaning chamber 303. The other path enters directly from the spray hole 310 and blows directly to the other spray hole 310. Under the action of the impact of the two paths of air, the impurities in the cleaning chamber 303 are ejected from the spray hole 310, and the surface of the formwork is air-cleaned. Thereby, it is avoided that impurities affect the spraying effect, and at the same time, the overall work efficiency is improved.

[0069] Add spraying liquid inside the liquid storage tank 504. When the template arrives detected by the position sensor 501, control the liquid extraction pump 505 to work, pump the liquid in the liquid storage tank 504 towards the liquid outlet pipe 506, and discharge it into the distribution box 507 through the liquid outlet pipe 506. At this time, the liquid is evenly sprayed onto the upper surface of the template through the spray pipe 508 and the nozzle, and the entire upper surface is completely covered. Control the third motor 603 to work, drive the coating roller 601 to rotate. At this time, the soft cloth 602 abuts against the upper surface of the template, so as to wipe the upper surface of the template sprayed with the spraying liquid. Thus, the paint on the upper surface of the template is further evenly distributed, ensuring the consistency and aesthetics of the coating. During this process, the paint accumulated on the soft cloth 602 is scraped off by the scraping plate 604, causing the paint to fall onto the liquid collecting plate 605, and the paint is collected into the interior of the liquid collecting tank 606 through the inclined liquid collecting plate 605 for recycling, facilitating subsequent reuse or disposal. Control the exhaust fan 704 to work through the motor, thereby forming a negative pressure inside the processing tank 701, and then collecting the mist generated in the spraying chamber 503 into the processing tank 701 through the air collecting hood 707 and the air collecting pipe 706. At this time, the mist passes through the filter plate 702 to filter the gas and is discharged from the exhaust fan 704, avoiding environmental pollution. The liquid falls to the bottom of the processing tank 701, and the liquid is discharged from the drain pipe 705 through the inclined bottom surface for liquid recycling.
