Description

Technical Field

[0001] This utility model relates to the field of fire door surface spraying technology, specifically to a spraying equipment for an expansion flame-retardant coating on the surface of a fire door. Background Technology

[0002] In modern building safety systems, fire doors, as key fire-resistant partition components that prevent the spread of fire and ensure the safe evacuation of personnel, have crucial fire resistance performance. To improve the fire resistance of fire doors, spraying an intumescent flame-retardant coating on their surface is a widely used and effective method. This coating rapidly expands and foams when heated, forming a porous, heat-insulating carbonaceous protective layer that effectively slows heat transfer to the door, thereby enhancing the fire door's fire resistance limit. Currently, there are many types of spraying equipment on the market for applying intumescent flame-retardant coatings to fire door surfaces, but they generally have some problems that urgently need to be solved. While some spraying equipment can perform the spraying work, it cannot fix fire doors of different sizes, and it cannot clean and dry the fire doors before and after spraying.

[0015] Compared with the prior art, this utility model provides a spraying device for an intumescent flame-retardant coating on the surface of a fire door, which has the following beneficial effects:

[0016] 1. The spraying equipment for the intumescent flame-retardant coating on the surface of the fire door, through a fixed mechanism, when it is necessary to spray the intumescent flame-retardant coating on the surface of the fire door, firstly, the fire door is placed on top of the placement frame and in the middle position. The width of the fire door to be sprayed cannot exceed the width of the placement frame. The first cylinder drives the connecting plate and the moving frame to move. When the connecting plate moves, the top of it slides on the bottom of the processing table, which at the same time drives the fixed rod to move inside the fixed block, ensuring the stability of the connecting plate and the moving frame during movement. When the moving frame moves, it drives the mounting plate and the clamping plate to move. By setting up two sets of symmetrically distributed fixing blocks, a first cylinder, clamping plates, and other components, the fire door can be fixed on both sides. At the same time, it can ensure that the fire door is centered on the top of the processing table, ensuring stability and improving the quality of subsequent spraying. The fan inside the mounting frame can blow air onto the surface of the fire door before spraying, promptly removing dust, debris, etc., ensuring a clean spray surface. This helps the intumescent flame-retardant coating to better adhere to the surface of the fire door. After spraying, the airflow generated by the fan can accelerate the drying efficiency of the coating.

[0017] 2. The spraying equipment for the fire door surface expansion flame-retardant coating, through its spraying mechanism, after the fire door is fixed by the placement frame and clamps, the servo motor drives the threaded rod to rotate, which can precisely control the movement of the support platform, thereby driving the nozzle to move and spray evenly and stably from right to left along the surface of the fire door. The second cylinder can flexibly adjust the height of the nozzle to adapt to fire doors of different thicknesses, ensuring that the nozzle and the surface of the fire door maintain a suitable distance during the spraying process, ensuring the uniformity and consistency of the spraying. At the same time, the combination of the distributor, nozzle, liquid tank, hose and pump body can achieve stable delivery and precise distribution of the coating, improving the utilization rate of the coating. The distributor is concave, which can avoid the phenomenon of coating scattering during the spraying process and ensure the quality of the spraying. Attached Figure Description

[0035] Example 2

[0036] Please see Figure 1-7Furthermore, based on Embodiment 1, the spraying mechanism 3 further includes a servo motor 31, which is fixedly connected to the right side of the processing table 21. A threaded rod 32 is fixedly connected to the left side of the servo motor 31. A support platform 33 is threadedly connected to the outer periphery of the threaded rod 32. A support frame 34 is fixedly connected to the top of the support platform 33. A second cylinder 38 is fixedly connected to the top of the support frame 34. A distributor 392 is fixedly connected to the bottom of the second cylinder 38. A limit rod 391 is fixedly connected to the top of the distributor 392.

A hose 37 is fixedly connected to the front side of the liquid storage tank 35. The hose 37 is fixedly connected to the rear side of the distributor 392. A pump body 36 is fixedly connected to the outer periphery of the hose 37. A limit block 39 is fixedly connected to the outer periphery of the hose 37. The limit block 39 is fixedly connected to the rear side of the distributor 392.

[0037] The threaded rod 32 is rotatably connected to the processing table 21 on the left side. The support platform 33 is slidably connected to the top of the processing table 21. The limiting rod 391 is slidably connected to the inside of the support frame 34. The pump body 36 is fixedly connected to the top of the support platform 33, so that the support platform 33 can be moved under the action of the threaded rod 32. The distributor 392 is concave in shape. The limiting block 39 is slidably connected to the inside of the support frame 34, so that it can follow the distributor 392 under the action of the limiting block 39. At the same time, it can drive the hose 37 to move with the distributor 392.

[0038] In actual operation, when this device is used, and when it is necessary to spray an intumescent flame-retardant coating on the surface of a fire door, the fire door is first placed on top of the placement rack 22 and in the middle position. The width of the fire door to be sprayed cannot exceed the width of the placement rack 22. The first cylinder 24 drives the connecting plate 26 and the moving frame 27 to move. When the connecting plate 26 moves, its top will slide at the bottom of the processing table 21, and at the same time, it will drive the fixing rod 25 to move inside the fixing block 23, ensuring the stability of the connecting plate 26 and the moving frame 27 when they move. When the moving frame 27 moves, it will drive the mounting plate 28 and the clamping plate 29 to move. By setting two sets of symmetrically distributed fixing blocks 23, first cylinder 24, clamping plate 29 and other components, the fire door can be fixed on the left and right sides. At the same time, it can ensure that the fire door is in the middle position on the top of the processing table 21, ensuring stability and improving the quality of subsequent spraying.

[0039] When the fixing is completed, the fan 292 inside the mounting frame 291 can blow air on the surface of the fire door before spraying, remove dust, debris and other impurities from the surface in time, ensure that the sprayed surface is clean, and help the intumescent flame retardant coating to better adhere to the surface of the fire door. At the same time, the required paint is added to the liquid storage tank 35.

[0040] Simultaneously, the servo motor 31 drives the threaded rod 32 to rotate, which can precisely control the movement of the support platform 33, thereby driving the nozzle 393 to move and spray evenly and stably from right to left along the surface of the fire door. The second cylinder 38 can flexibly adjust the height of the nozzle 393 to adapt to fire doors of different thicknesses, ensuring that the nozzle 393 maintains a suitable distance from the surface of the fire door during the spraying process, ensuring the uniformity and consistency of the spraying. During the movement, the pump body 36 delivers the paint in the storage tank 35 to the distributor 392 through the hose 37, and sprays it out through the nozzle 393 to carry out the spraying work. When the distributor 392 moves, it will drive the limit block 39 to move, thereby driving the hose 37 to move with the distributor 392 to ensure stable material supply. The distributor 392 is concave, which can prevent the paint from scattering during the spraying process and ensure the spraying quality.

[0041] After the spraying is completed, the air force generated by the fan 292 can accelerate the drying efficiency of the paint. After drying, the fire door can be flipped over and the other side can be sprayed. In this case, the first cylinder 24, the second cylinder 38, the servo motor 31 and the pump body 36 can be connected to the same PLC control system to ensure the coordinated work between the equipment. The PLC control system is existing technology, and those skilled in the art know only the working method and process of this equipment.
