Description

Technical Field

[0001] This utility model relates to the field of armored door surface treatment technology, specifically a pure copper armored door surface spraying device. Background Technology

[0002] Armored doors are assembled from inner and outer decorative panels, a six-sided box-shaped steel core, side edge protectors, and locks. Pure copper armored doors are high-end security doors that combine the structure of armored doors with copper finishes. The internal structure is a robust steel frame, while the front and back surfaces are finished with copper. This structure gives the copper door not only the high security of an armored door but also the luxury and aesthetics of a copper door. Painting the surface is an important step in the manufacturing process of pure copper armored doors, enhancing both the door's texture and its overall appearance.

[0003] Chinese Patent Publication No. CN219765747U, authorized on September 29, 2023, discloses a surface spraying device for security doors, comprising a first transmission device and a second transmission device. The top of the spray gun has a paint hopper, and an auxiliary spray gun is located on one side of the spray gun. A stirring device is installed inside the paint hopper, penetrating the hopper wall and connected to a motor. The semi-permeable membrane has a low-center arc-shaped structure. The first transmission device includes a set of support columns, with transmission rollers positioned between the support columns. A transmission net is mounted on the support of the transmission rollers, and protrusions are located at the nodes on both sides of the upper surface of the transmission net. This invention improves the stability of door panel placement and transmission, increases the spraying efficiency of the door panel, saves paint, improves the mixing degree and uniformity of the paint, enhances the paint finish, and facilitates better waste collection.

[0004] Existing spraying equipment uses a spray gun to spray paint onto the surface of the armored door. This spraying method can only spray one side of the armored door at a time. After one side is finished, the armored door needs to be flipped over and sprayed again, which increases the workload of the spraying operation, reduces the efficiency of the armored door spraying, and cannot meet the usage requirements. Utility Model Content

This coating method can only coat one side of the armored door at a time. After one side is finished, the armored door needs to be flipped over and coated again, which increases the workload of the coating operation, reduces the coating efficiency of the armored door, and cannot meet the needs of use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pure copper armored door surface spraying device, comprising a loading platform, a discharging platform, and a spraying chamber. The spraying chamber is disposed between the loading platform and the discharging platform. A first hollow frame and a second hollow frame are disposed inside the spraying chamber, and the first and second hollow frames are fixedly connected to the spraying chamber. Multiple nozzles are equidistantly arranged on the inner side of the second hollow frame, and the nozzles are integrally connected to the second hollow frame. A storage tank and a spraying pump are disposed above the spraying chamber, and the storage tank and the spraying pump are connected to the spraying chamber by screws. The spraying pump is connected to the storage tank. A conveying pipe is disposed between the spraying pump and the second hollow frame. A perforated plate is disposed on the inner side of the first hollow frame, and the perforated plate is fixedly connected to the first hollow frame. A hot air blower assembly is disposed above the spraying chamber, and the hot air blower assembly is connected to the spraying chamber by screws. The hot air blower assembly is connected to the first hollow frame.

[0007] Preferably, a conveying roller is provided at both ends of the loading platform, and there are two conveying rollers. The conveying rollers are rotatably connected to the loading platform. A conveyor belt is provided between the two conveying rollers and is drivenly connected to the conveying rollers. A motor is provided on one side of the loading platform and is connected to the loading platform by screws. The output end of the motor is connected to one end of the conveying roller.

Two horizontal rollers are arranged on the inner side of the spraying chamber, and the horizontal rollers are rotatably connected to the spraying chamber. The horizontal rollers are arranged on one side of the second hollow frame. The upper ends of the conveyor belt, support rollers and horizontal rollers are flush.

[0009] Preferably, a support plate is provided on the inner side of the loading platform, and the support plate is fixedly connected to the loading platform. The support plate is located below the conveyor belt and is in close contact with the conveyor belt.

[0010] Preferably, a connecting frame is provided on both sides of the loading platform, and there are two connecting frames. The connecting frames are fixedly connected to the loading platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model device, through the arrangement of a horizontal roller, a spray pump, a second hollow frame, and spray nozzles, draws paint stored in the storage tank through the spray pump and sends it into the second hollow frame through the conveying pipe. The paint is then evenly sprayed onto the armored door through multiple spray nozzles, allowing multiple surfaces of the armored door to be sprayed at one time. The horizontal roller contacts the bottom of the armored door, supporting the sprayed armored door and ensuring that the conveyed armored door is in a horizontal state, preventing the armored door from tilting due to the different weights at both ends, and improving the spraying efficiency of the armored door surface.

[0015] 2. The utility model device is equipped with a hot air blower assembly, a first hollow frame, a perforated plate and a temperature sensor. The hot air blower assembly generates hot air and sends it into the first hollow frame.

The temperature sensor measures the drying temperature, which makes it easy to adjust the drying temperature and accurately control the drying temperature.

[0016] 3. The utility model device, through the setting of a connecting plate, a vertical rod and an electric push rod, drives the connecting plate to move, and brings the vertical rod into contact with the side end faces on both sides of the armored door, thereby limiting the transported armored door and ensuring that the transported armored door is in the middle of the second hollow frame, thus improving the surface coating effect of the armored door.
