Description

Technical Field

[0001] The utility model belongs to the technical field of paint spraying equipment, in particular to a uniform paint spraying device used for spraying automobile metallic paint. Background Art

[0002] As an outdoor means of transportation, cars are exposed to long-term erosion by atmospheric media such as moisture, oxygen, industrial atmosphere, and carbon dioxide. Car paint forms a firmly adhered continuous film layer on the car, which can prevent its surface from chemically or electrochemically reacting with the surrounding media, and prevent or delay the occurrence and development of damage to the car. Therefore, in the production process of the car, it is very important to paint the car surface. The staff will use the paint spraying device to paint the car body parts, and now some cars will also be sprayed with metallic paint, which protects the car surface while making it more beautiful.

[0003] However, there are some problems with the existing technology: when painting a car bumper, the existing painting device usually has a nozzle at a fixed height above the bumper, and paints the bumper with reciprocating motion. Due to the curved ends of the bumper, the nozzle is at a large distance from the bumper surface when it is above the two ends of the bumper, which reduces the spraying effect. This will cause the paint surface at both ends of the bumper to be thinner, affecting production quality. Therefore, we propose a uniform painting device for spraying automotive metallic paint. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a uniform paint spraying device for automobile metallic paint spraying, which makes the overall spraying more uniform by keeping the spray head at a close distance to the bumper surface.

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown, an embodiment of the utility model provides a uniform paint spraying device for automobile metallic paint spraying, comprising a frame 1, an inner cavity of the frame 1 is provided with a bracket 2, the inner cavity of the frame 1 is also provided with a block 3 located above the bracket 2, the block 3 and the frame 1 are connected by a driving mechanism, a first slide rail 4 is fixedly mounted on the block 3, a slider 5 is slidably connected to the first slide rail 4, a nozzle 6 is provided on the slider 5, the nozzle 6 and the slider 5 are connected by a power mechanism, a square plate 7 is fixedly mounted on the inner wall of the frame 1, an arc groove 8 is opened on the square plate 7, a round rod 9 is fixedly connected to the slider 5, the other end of the round rod 9 extends to the inside of the arc groove 8, a pressurizing mechanism is also provided on the top of the frame 1, and the nozzle 6 and the pressurizing mechanism are connected by a hose 20.

[0023] Furthermore, the driving mechanism includes a driving motor 10, which is fixedly mounted on the outer wall of the frame 1. The output shaft of the driving motor 10 is fixedly sleeved with a screw rod 11. The block 3 is threadedly sleeved on the outer surface of the screw rod 11. The inner wall of the frame 1 is fixedly connected with a guide rod 12, and the block 3 and the guide rod 12 are slidingly connected.

[0024] By starting the drive motor 10 to rotate the screw rod 11 , the block 3 can drive the spray head 6 to move left or right, thereby performing an overall painting operation on the car bumper placed on the bracket 2 .

[0025] Furthermore, the power mechanism includes a brake motor 13 , which is fixedly mounted on the slider 5 . The output shaft of the brake motor 13 is fixedly sleeved with a rotating shaft 14 , and the other end of the rotating shaft 14 is fixedly connected to the nozzle 6 .

[0026] When the spray head 6 moves to the top of both sides of the car bumper, the operation of the brake motor 13 can rotate the spray head 6, so that the nozzle of the spray head 6 can always face the car bumper, thereby achieving a better spraying effect.

[0027] Furthermore, the pressurizing mechanism includes a paint box 15 , which is fixedly mounted on the top of the frame 1 . The paint box 15 is fixedly connected to a booster pump 16 , and both ends of the hose 20 are fixedly connected to the booster pump 16 and the nozzle 6 .

[0028] By starting the booster pump 16, the paint in the paint box 15 can be extracted and transported to the inside of the spray head 6 through the hose 20, so that the paint can be sprayed out from the spray head 6 to perform a painting operation on the car bumper.

[0029] Furthermore, a second slide rail 17 is fixedly installed at the bottom of the inner wall of the frame 1, and the bracket 2 is slidably connected to the second slide rail 17. An electric push rod 18 is fixedly connected to the inner wall of the frame 1, and the telescopic end of the electric push rod 18 is fixedly connected to the bracket 2.

[0030] By starting the electric push rod 18 to push the bracket 2 out, it is convenient for the staff to place or remove the car bumper, and starting the electric push rod 18 to drive the bracket 2 to move is also convenient for adjusting the width center of the car bumper to be located directly below the spray head 6 to ensure the spraying effect.

[0031] Furthermore, a heater 19 is fixedly mounted on the outer wall of the frame 1 , and an air outlet pipe of the heater 19 passes through the outer wall of the frame 1 and extends to the interior of the frame 1 .

[0032] After the painting work is completed, the staff can start the heater 19 to blow hot air to the bumper, thereby quickly drying the paint surface on the bumper, thereby improving work efficiency.

[0033] Furthermore, the hose 20 is configured to be threaded, and a wear-resistant layer is provided on the surface of the hose 20 .

[0034] The hose 20 is threaded and has good extensibility and elasticity so that it can follow the movement of the spray head 6 to perform the painting operation. At the same time, the wear-resistant layer on the surface of the hose 20 reduces the wear of the hose 20 caused by frequent contact between the round rod 9 and the hose 20.

[0035] When in use, the staff can first start the electric push rod 18 to push the bracket 2 to move, then place the bumper on the top of the bracket 2, and then start the electric push rod 18 so that the bumper is directly under the spray head 6, and then start the booster pump 16 and the drive motor 10, so that the booster pump 16 pressurizes the paint in the paint box 15 and transports it to the inside of the spray head 6 for spraying. At the same time, the screw rod 11 rotates to make the block 3 drive the spray head 6 and the round rod 9 to move left or right to spray the bumper. When the spray head 6 moves to the top position on both sides of the bumper, the round rod 9 will continue to move along the inner wall of the arc groove 8, thereby driving the slider 5 to move downward, and then making the spray head 6 move downward to maintain a close distance from the bumper, and the staff can start the brake motor 13 to make the rotating shaft 14 drive the spray head 6 to rotate, so that the nozzle of the spray head 6 is always facing the surface of the bumper, thereby achieving a more uniform effect of spraying the entire bumper. After the spraying is completed, the staff can start the heater 19 to dry the paint surface to improve work efficiency.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
