Description

Technical Field

[0001] This utility model relates to the technical field of spray painting devices, specifically a fire door spray painting device. Background Technology

[0002] Fire doors are typically installed in fire-resistant compartments and evacuation stairwells, and are fire-resistant separation devices that require a certain degree of fire resistance. Fire doors play a significant role in firefighting efforts. They are doors that meet the requirements of fire resistance stability, heat insulation, and integrity for a certain period of time. Painting is a crucial step in the production of fire doors. The main purpose of painting is to form a protective coating on the surface of the fire door, thereby improving its fire resistance and appearance.

[0003] The prior art, disclosed in CN221907915U, provides a painting device for processing steel fire doors, including a workbench. An adjustment component is installed inside the workbench, and a movable plate is fixedly mounted on the top surface of the adjustment component. A drive component is installed inside the movable plate, and a rotating shaft is rotatably mounted inside the movable plate. The fixing component causes a pressure plate to move downwards and clamp the fire door, thus securing it. A cleaning component causes a cleaning brush to move upwards and contact the fire door, cleaning its surface. The drive component rotates the rotating shaft, which in turn rotates the mounting bracket, allowing the fixed fire door to rotate for painting both sides. A paint supply component injects paint from the paint tank into a branch pipe, which is then sprayed out through a nozzle. A lateral movement component moves the branch pipe and nozzle, resulting in more even painting of the fire door.

[0004] The aforementioned patent primarily uses a pressing method on both sides to fix the fire door. However, because the fire door is fixed at both ends by pressure plates, the areas where the pressure plates are fixed cannot be sprayed with paint. Users then have to perform manual painting operations, making the overall process of painting fire doors with this steel fire door processing painting device quite cumbersome and inconvenient for users. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a fire door painting device, which solves the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire door painting device, comprising a device body for fixing and flipping fire doors. The device body includes a table, on which a paint sprayer for painting fire doors is fixedly mounted. A clamping assembly and a mounting frame are mounted on the table. A first fixed-rotation assembly for supporting the fire door is fixedly mounted on the top of the mounting frame. The clamping assembly includes a fixed frame that can move on the table. A second fixed-rotation assembly is rotatably mounted on the side of the fixed frame near the mounting frame. The second fixed-rotation assembly includes a U-shaped plate fixed to the fixed frame. Rotary shafts are rotatably mounted at the upper and lower ends of the U-shaped plate. The rotating shafts are respectively fixedly mounted with a first rotating plate and a second rotating plate for supporting the fire door. The second fixed-rotation assembly cooperates with the first fixed-rotation assembly to fix and flip the fire door, thereby allowing the fire door painting device to paint two fire doors simultaneously, greatly improving the efficiency of fire door painting.

[0007] Furthermore, a second micro motor is fixedly installed on the upper end of one side of the U-shaped plate within the second rotating assembly, and a first micro motor is fixedly installed on the lower end of the side of the U-shaped plate away from the second micro motor. The output end of the first micro motor is fixedly connected to the rotating shaft where the second rotating plate is located, and the output end of the second micro motor is fixedly connected to the rotating shaft. Multiple spring posts are fixedly installed on the side of the first rotating plate near the first micro motor, and an adhesive plate for attaching to the fire door is fixedly installed on the end of each spring post away from the first rotating plate. Springs and adhesive plates are also sequentially fixedly installed on the side of the second rotating plate near the first rotating plate, and multiple friction protrusions are fixedly installed on the side of the adhesive plate away from the spring posts. The multiple friction protrusions on the side of the adhesive plate away from the spring posts increase the friction between the adhesive plate and the fire door, making the fire door less likely to fall off and greatly improving the firmness of the fire door painting device in fixing the fire door.

[0008] Furthermore, a first motor (225) for flipping the fire door is placed inside the fixed frame (224), and the output end of the first motor (225) is fixedly connected to the second fixed-rotation assembly (226). The output end of the first motor (225) is fixedly connected to the second fixed-rotation assembly (226), so that the rotation of the first motor (225) can directly drive the fire door to rotate accordingly, greatly improving the efficiency of the fire door flipping.

[0009] Furthermore, the clamping assembly also includes a fixing plate fixed to the table body. An electric actuator is fixedly mounted on the side of the fixing plate near the mounting frame, and the telescopic end of the electric actuator is fixed to the fixing frame body. The fixing of the telescopic end of the electric actuator to the fixing frame body allows the electric actuator to directly move the fixing frame body, improving the overall integrity of the internal structure of the fire door painting device.

[0010] Furthermore, the clamping assembly also includes a slide rail fixed to the table body, and the fixing frame moves at its upper limit on the slide rail.

[0011] Furthermore, the paint spraying body includes a U-shaped frame fixed on the table, a second motor is fixedly installed on one side of the U-shaped frame, a threaded shaft is fixedly connected to the output end of the second motor, and a paint spraying component is fixedly installed at the end of the U-shaped frame away from the table. The paint spraying component includes a movable block, which moves at the upper limit of the threaded shaft.

[0012] Furthermore, the painting assembly also includes a paint can fixed on a U-shaped frame. A pressure pump is fixedly installed inside the paint can, and a pipe is fixedly connected to the outlet of the pressure pump. A spray nozzle for painting the fire door is fixedly connected to the lower end of the pipe. The pipe penetrates and is fixed within a movable block, which moves the spray nozzle along a threaded shaft. This movement of the spray nozzle along the threaded shaft allows the fire door painting device to paint the entire fire door in one operation, greatly improving the ease of use of the device.

[0013] Furthermore, the pipe is a corrugated pipe. The corrugated pipe design ensures that the nozzle is not obstructed when moving with the movable block, thus improving the practicality of the fire door painting device. Beneficial effects

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention sets the fixed-rotation component into a two-section structure that can swing up and down. When the fire door fixed to the fixed-rotation component is being painted, the upward-facing rotating plate can be rotated, so that the paint sprayer can spray the entire fire door. After the fire door is flipped over, the other rotating plate is rotated, which greatly improves the comprehensiveness of the fire door painting device for painting fire doors.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0024] Example

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6This application will be further described in detail below. A fire door spraying device is characterized by comprising a device body 2 for fixing and rotating a fire door. The device body 2 includes a table 21, on which a spraying body 1 for spraying paint onto the fire door is fixedly mounted. A clamping assembly 22 and a mounting frame 24 are mounted on the table 21. A first fixing and rotating assembly 23 for supporting the fire door is fixedly mounted on the top of the mounting frame 24. The clamping assembly 22 includes a fixed frame 224 movable on the table 21. A second fixing and rotating assembly 226 is rotatably mounted on the side of the fixed frame 224 near the mounting frame 24. The second fixing and rotating assembly 226 includes a U-shaped plate fixed to the fixed frame 224. Rotating shafts 2262 are rotatably mounted at the upper and lower ends of the U-shaped plate. Rotating shafts 2262 are respectively fixedly mounted with... The first rotating plate 2263 and the second rotating plate 2268 support the fire door. A second micro motor 2265 is fixedly installed on the upper end of one side of the U-shaped plate within the second fixed-rotation assembly 226. A first micro motor 2261 is fixedly installed on the lower end of the side of the U-shaped plate away from the second micro motor 2265. The output end of the first micro motor 2261 is fixedly connected to the rotating shaft of the second rotating plate 2268. The output end of the second micro motor 2265 is fixedly connected to the rotating shaft 2262. Multiple spring posts 2264 are fixedly installed on the side of the first rotating plate 2263 near the first micro motor 2261. An adhesive plate 2266 for fitting the fire door is fixedly installed on the end of each spring post 2264 away from the first rotating plate 2263. The second rotating plate 2268 is located on the side near the first rotating plate 2263. Springs and bonding plates are also fixedly installed in sequence. Multiple friction protrusions 2267 are fixedly installed on the side of the bonding plate 2266 away from the spring post 2264. A first motor 225 for flipping the fire door is placed inside the fixing frame 224. The output end of the first motor 225 is fixedly connected to the second fixed-rotation assembly 226. The clamping assembly 22 also includes a fixing plate 221 fixed to the table 21. An electric push rod 222 is fixedly installed on the side of the fixing plate 221 near the mounting frame 24. The telescopic end of the electric push rod 222 is fixed to the fixing frame 224. The clamping assembly 22 also includes a slide rail 223 fixed to the table 21. The fixing frame 224 moves at its upper limit on the slide rail 223. The paint sprayer 1 includes a U-shaped frame 11 fixed to the table 21. A second motor 14 is fixedly installed on one side of the U-shaped frame 11. The output end of the second motor 14 is fixedly connected to a threaded shaft 12. A paint spraying assembly 13 is fixedly installed at the end of the U-shaped frame 11 away from the table body 21. The paint spraying assembly 13 includes a movable block 132, which moves at the upper limit of the threaded shaft 12. The paint spraying assembly 13 also includes a paint can 133 fixed on the U-shaped frame 11. A pressure pump 134 is fixedly installed inside the paint can 133. A pipe 135 is fixedly connected to the outlet end of the pressure pump 134. A nozzle 131 for spraying paint on fire doors is fixedly connected to the lower end of the pipe 135. The pipe 135 penetrates and is fixed inside the movable block 132. The movable block 132 is used to move the nozzle 131 on the threaded shaft 12. The pipe 135 is a corrugated pipe.

[0026] Since paint is added to the paint can 133 and one end of the pressure pump 134 is connected to the paint and the other end is connected to the pipeline 135, when the pressure pump 134 is running, it can directly draw out the paint from the paint can 133 and spray it out from the nozzle 131. The nozzle 131 is long and the threaded shaft 12 can move the nozzle 131 laterally. Therefore, the paint sprayed from the nozzle 131 can directly paint the entire side of the fire door, which greatly improves the efficiency of the fire door painting device for fire door painting.

[0027] Since the first micro motor 2261 controls the rotation of the second rotating plate 2268 and the second micro motor 2265 controls the rotation of the first rotating plate 2263, when the second rotating plate 2268 supports the fire door, the user can activate the second micro motor 2265 to make the first rotating plate 2263 swing upward and be perpendicular to the second rotating plate 2268, so that the paint sprayer 1 can spray paint on one side of the fire door. The self-locking function of the first micro motor 2261 and the second micro motor 2265 can make the fire door firmly fixed on the first rotating plate 2263 or the second rotating plate 2268.

[0028] Since the bonding plate 2266 extends outwards at all times through the spring column 2264, when the fire door is located between the two bonding plates 2266, the elastic force of the spring column 2264, combined with the increased friction of the friction protrusion 2267, enhances the gripping force of the bonding plate 2266 on the fire door. When the first motor 225 runs and rotates the fire door, the probability of the fire door falling off is greatly reduced.

[0029] Since the movement of the fixed frame 224 is limited by the slide rail 223, when the electric actuator 222 is running, the fixed frame 224 can move smoothly within the slide rail 223. Unless otherwise specified, all internal mechanical structures are threaded. To better visualize the technical features, bolt connections are appropriately hidden in the diagram. Before using the fire door painting device, the user places one end of the fire door to be painted on the mating plate of the second rotating plate 2268, and the other end on the corresponding mating plate within the first fixed assembly 23. The user then activates the electric actuator 222, which causes the fixed frame 224 to slide on the slide rail 223, causing one end of the fire door to abut against the inner wall of the second rotating plate 2268, thus securing the fire door. The user then activates the pressure pump 134 and the second motor 14. Paint sprayed from the nozzle 131, combined with the movable block 132, propels the nozzle... Moving 131 allows for the complete painting of one side of the fire door. After one side of the fire door is painted, the user activates the second micro motor 2265, which causes the first rotating plate 2263 to swing downwards, allowing the bonding plate 2266 to adhere to the fire door. The elasticity of the spring column 2264 and the friction protrusion 2267 increase the gripping force of the bonding plate 2266 on the fire door. Then, the user activates the first motor 225, whose rotation causes the entire fire door to flip. After the fire door has flipped, the user activates the first micro motor 2261 to flip the second rotating plate 2268 upwards. By following these steps, the other side of the fire door is painted. This allows the fire door painting device to paint both sides of the fire door, greatly reducing the difficulty of operation for the user and significantly improving the practicality of the fire door painting device.

[0030] The working principle of this utility model is explained below: Fire door spray painting device.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
