The feeding methods of the spray gun are divided into three types: pressure type, siphon type and gravity type. The thickness and uniformity of the spraying directly determine the effect of the spraying. The traditional spraying method usually sprays the surface of the workpiece by moving the position of the spray gun, which easily causes uneven coating on the surface of the workpiece.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See also Figure 1-4 The utility model provides an automatic spraying device, including a sprayer 1 and a conveyor 2, wherein the conveyor 2 is installed on both sides of the sprayer 1, and symmetrically arranged connecting plates 8 are arranged on the edges of both sides of the top surface of the conveyor 2, and a through first through hole is arranged inside the connecting plate 8, and a sliding rod 4 is slidably arranged inside the first through hole, and the inner end of the sliding rod 4 is connected to a limit plate 3 arranged on the surface of the conveyor 2, and the sliding rod 4 can drive the limit plate 3 to move on the surface of the conveyor 2, and a rotating plate 13 is arranged on the top of the sprayer 1, and one end of the rotating plate 13 is rotatably connected to the top surface of the sprayer 1 through a connecting shaft 14, and the other end is connected to the cover plate 12.

[0025] In one embodiment of the present invention, the sliding rod 4 is provided with evenly arranged limiting grooves.

[0026] An embodiment of the utility model is that a second through hole perpendicular to the first through hole is provided on the top of the connecting plate 8, and a card block 5 is slidably provided in the second through hole. A telescopic connection structure is formed between the card block 5 and the connecting plate 8. By pushing the card block 5, the surface of the card block 5 performs telescopic activities inside the connecting plate 8. The card block 5 matches the limiting groove on the sliding rod 4 to limit the sliding rod 4. When the length of the sliding rod 4 needs to be adjusted, the card block is removed from the second through hole, and then the length of the sliding rod 4 is adjusted. After the adjustment is completed, the card block is inserted into the second through hole for limiting.

[0027] In an embodiment of the utility model, the card block 5 can be in the following form: a through slot is provided inside the card block 5, a fixing block 6 is provided in the through slot, the length of the fixing block 6 is longer than the through slot, and after the fixing block passes through the through slot, both ends are fixed on the inner wall of the second through hole of the connecting plate 8, the width of the fixing block 6 is smaller than the width of the through slot, so that the card block 5 can move up and down at both ends of the fixing block 6, and a locking spring 7 is also provided in the through slot, the locking spring 7 is located at the bottom of the fixing block 6, one end of the locking spring 7 is connected to the bottom of the fixing block 6, and the other end is connected to the bottom wall of the through slot. When it is necessary to adjust the length of the sliding rod 4, the card block is pulled out from the second through hole. Since there is a fixed block in the through groove, when the card block 5 is pulled out, the locking spring 7 is stretched upward together, but since the fixed block remains stationary, the fixed block squeezes the card and the spring, so that the locking spring 7 has a downward stretching force, so that it can be ensured that the card block 5 will not fall out of the second through hole of the connecting plate 8. Therefore, by pulling the card block, the surface of the card block and the sliding rod are separated from each other, and then the sliding rod is pushed, so that the sliding rod drives the limit plate to move, thereby adjusting the distance between the two limit plates, and then releasing the card block, the card block is elastically engaged with the surface of the sliding rod through the locking spring, and then the distance between the two limit plates is adjusted, so that the workpiece can be accurately moved on the spray machine.

[0028] In the embodiment of the utility model, a connecting ear 9 is fixedly connected to the side wall of the sprayer 1, and a tension spring 10 is connected inside the connecting ear 9. Through the connecting ear 9, the elastic action of the tension spring 10 pulls the side ear 11, and the end of the tension spring 10 away from the connecting ear 9 is connected to the side ear 11;

[0029] In the embodiment of the utility model, a handle is provided on the cover plate 12 to facilitate opening the cover plate 12 .

[0030] In an embodiment of the utility model, a threaded groove is provided at the bottom of the cover plate 12, and a positioning block 17 is provided on the surface of the sprayer 1 opposite to the threaded groove. A rotating plate 16 is slidably provided on the positioning block 17, and a threaded rod 15 is provided on the rotating plate 16. The rotating plate 16 can move along the threaded rod 15, so that the threaded rod 15 cooperates with the threaded groove to position the cover plate 12.

[0031] One side of the side ear 11 is installed on the side of the cover plate 12, and the spring elasticity of the tension spring 10 prevents the connecting ear 9 from falling off after opening. A rotating plate 13 is fixedly connected to one side of the top of the cover plate 12, and a connecting shaft 14 is connected to the inside of the rotating plate 13. The rotating plate 13 forms a rotating connection structure with the sprayer 1 through the connecting shaft 14. By pulling the cover plate 12, the cover plate 12 rotates with the connecting shaft 14 as the center through the rotating plate 13, so that the cover plate 12 can be opened more easily. A threaded rod 15 is connected to the surface of the cover plate 12, and a threaded connection structure is formed between the threaded rod 15 and the cover plate 12. A rotating plate 16 is fixedly connected to the surface of the threaded rod 15, and the rotating plate 16 is rotatably connected to the inside of the positioning block 17. One side of the positioning block 17 is fixedly connected to the sprayer 1, and the threaded connection between the top of the threaded rod 15 and the cover plate 12 is used to position the cover plate 12.

[0032] Therefore, by rotating the threaded rod counterclockwise, the surface of the threaded rod and the cover are separated from each other, and the rotating plate slides inside, and then the cover is pulled. The cover rotates around the connecting shaft through the turning plate, thereby opening the cover and stretching the spring at the same time. The stretching spring tightens the cover, making it more convenient to inspect and maintain the interior of the sprayer.

[0033] In summary: Figure 1-4 As shown, when using the fully automatic spraying device, first pull the block 5 so that the surface of the block 5 and the sliding rod 4 are separated from each other, and then push the sliding rod 4 so that the sliding rod 4 drives the limit plate 3 to move, thereby adjusting the distance between the two limit plates 3, and then release the block 5. The block 5 is elastically engaged with the surface of the sliding rod 4 through the engagement spring 7, thereby adjusting the distance between the two limit plates 3, so that the workpiece can be accurately moved on the spraying machine 1, and the threaded rod 15 is rotated counterclockwise. The surface of the threaded rod 15 and the cover plate 12 are separated from each other, and the rotating plate 16 slides inside, and then the cover plate 12 is pulled, and the cover plate 12 is rotated with the connecting shaft 14 as the center through the rotating plate 13, so that the cover plate 12 is opened, and the spring 10 is stretched at the same time. The stretching spring 10 tightens the cover plate 12, so that the interior of the spraying machine 1 can be inspected and maintained more conveniently. This is the characteristic of the fully automatic spraying device.
