Description

TECHNICAL FIELD

[0001] The utility model relates to a spraying device, concretely relates to a replaceable spraying and storage integrated spraying device. BACKGROUND

[0002] When a ship is delivered and repaired, the ship's surface often needs to be painted, and the paint not only protects the metal from corrosion but also increases the aesthetic appearance. Currently, when painting a large area of metal surface such as the ship's surface, a worker usually uses a manual spray gun to spray paint. Because the area of the ship's surface is large, the spraying time is also long. Most of the long-time spraying operation is mechanical repetition, which increases the labor intensity of the worker and reduces the work efficiency. During spraying, the worker also needs to climb the ladder with the spray gun, which is very inconvenient and dangerous.

[0003] Because of the above limitations of manual operation, current research is focused on how to use a robot to replace manual operation for painting the ship's surface. The robot is suitable for mechanical repetition and various working conditions, and can replace manual operation for climbing the ladder to reduce the danger of the worker. One of the main methods of using a robot for spraying is to set a spraying device on a robot chassis that can climb the wall of the ship's surface, so that the robot chassis and the spraying device are combined to paint the surface of the ship's surface.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figures 1-4 This utility model discloses a replaceable spraying material integrated spraying device, comprising a frame 1. An air distribution chamber 3, a material replacement tank 2, and a negative pressure air chamber 5 are arranged at one end of the frame 1. All three are located on the upper surface of the frame 1, with the negative pressure air chamber 5 and the air distribution chamber 3 located on either side of the material replacement tank 2, clamping the tank 2 in the middle for a limiting function. To prevent the material replacement tank 2 from shifting during use, a clamp 12 is also provided on the upper surface of the frame 1. When the material replacement tank 2 is placed on the frame 1, it is fixed to the upper surface of the frame 1 by the clamp 12 engaging with the outer wall of the tank 2.

[0028] At the other end of the frame 1, there is a wind deflector 4, an atomizing head 7 and a position adjustment mechanism 6. The wind deflector 4 is located on the lower surface of the frame 1 and can provide shielding for the atomized paint during spraying to prevent external airflow from affecting the sprayed surface.

[0029] The structure of the position adjustment mechanism 6 is as follows Figure 4As shown, the position adjustment mechanism 6 is mounted on the upper surface of the frame 1 and positioned corresponding to the windshield 4. The movable end of the position adjustment mechanism 6 is connected to the atomizing head 7, which can drive the atomizing head 7 to move vertically within the windshield 4. In this embodiment, the position adjustment mechanism 6 includes a mounting frame 63 mounted on the frame 1. It has a U-shaped structure and includes two vertical plates and a horizontal plate at one end of the two vertical plates for connecting them. The other end of the vertical plates is mounted on the frame 1. An adjustment motor 61 is mounted on the outer surface of the horizontal plate. The output shaft of the adjustment motor 61 extends into the mounting frame 63 and is connected to a screw 62. A connecting frame 64 is provided between the two vertical plates. The screw 62 and the connecting frame 64 are threaded together to form a simple screw-nut mechanism. To ensure that the connecting frame 64 moves vertically without rotating, a slide rail 65 is provided on the inner side of one of the vertical plates. The slide rail 65 is arranged vertically, and the connecting frame 64 slides with the slide rail 65. The atomizing head 7 is connected to the connecting frame 64, which constitutes the movable end.

[0030] The gas distribution compartment 3 includes one air inlet and two air outlets, while the structure of the material exchange tank 2 is as follows: Figure 3 As shown, one end of the atomizing head 7 is provided with a pressurization port 21 and a pump feed port 22. The structure of the atomizing head 7 is as follows: Figure 2 As shown, it is equipped with an atomizing port 71 and a feed port 72. The paint that is atomized in the atomizing head 7 will be sprayed out from the spraying port of the atomizing head 7. In order to further enhance the installation stability of the material changing tank 2, a baffle 11 is provided on the upper surface of the frame 1. One end of the material changing tank 2 with the pressure port 21 faces the windshield 4, and the other end abuts against the baffle 11.

[0031] The air inlet of the air distribution chamber 3 is connected to the pressurized gas pipeline. One of the air outlets is connected to the atomization port 71 of the atomizing head 7 via an air pipe, and the other air outlet is connected to the pressurization port 21 of the material exchange tank 2 via an air pipe. The pump port 22 of the material exchange tank 2 is connected to the feed port 72 of the atomizing head 7 via a corrosion-resistant material pipe. In this way, when the gas in the pressurized gas pipeline enters the air distribution chamber 3, it is divided into two paths. One path enters the material exchange tank 2 through the pressurization port 21 to provide pumping pressure for the material exchange tank 2. The other path enters the atomizing head 7 through the atomization port 71. Due to the presence of pumping pressure, the paint in the material exchange tank 2 is pumped into the atomizing head 7 through the feed port 72. At this time, the gas entering the atomizing head 7 through the atomization port 71 mixes with the paint entering from the feed port 72, and finally sprays out from the spray nozzle of the atomizing head 7.

[0032] During spraying, paint mist escaping from the wind deflector 4 can impact the environment. Therefore, the negative pressure air chamber 5 is connected to the wind deflector 4 via pipeline to extract the escaping paint mist under negative pressure, preventing adverse environmental impact. A lifting ring 8 is also provided on the upper surface of the frame 1 for easy transport of the entire device. Furthermore, a safety rope can be connected to the lifting ring 8 during use to prevent the device from accidentally falling.

[0033] When using, first loosen clamp 12, put in the new material tank 2 and tighten clamp 12. Connect the pump port 22 of material tank 2 to the feed port 72 of atomizing head 7 through a material pipe. Connect the two air outlets of air path distribution chamber 3 to the atomizing port 71 of atomizing head 7 and the pressurizing port 21 of material tank 2 through air pipes. Then connect the air inlet of air path distribution chamber 3 to the pressurized gas pipeline. Then start supplying air. During the spraying process, if the wind deflector 4 comes into contact with the spraying surface, adjust the height of atomizing head 7 by adjusting motor 6. During spraying, open negative pressure air chamber 5 to continuously extract the escaping paint mist under negative pressure. When the paint in material tank 2 is used up, loosen clamp 12, remove the pipeline connected to pump port 22 and pressurizing port 21, replace with a new material tank 2, tighten clamp 12, and connect the pipeline before spraying. The entire device is easy to replace the material tank 2, and its structure is simple and easy to maintain.
