[0004] When using this spray gun to spray the inner wall of an object, especially the inner wall of a cylindrical object, the operator usually holds the handle and gradually inserts the nozzle installed at the lower end of the tube into the object to spray the liquid onto the inner wall. During the spraying process, the operator adjusts and changes the angle and direction of the nozzle by applying force to the handle.

[0005] The spray gun has a simple structure and is easy to use, but it also has obvious problems and defects. For example, it is time-consuming and laborious to use because it requires manual holding of the handle for a long time to adjust the nozzle angle and direction.

[0006] In view of the problems in the background art mentioned above, the present invention aims to provide a spray gun for spraying operations. Utility Model Content

Detailed Implementation

[0027] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Example

[0029] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides a spray gun for spraying operations, the spray gun comprising:

[0030] The movable plate 3, the adjusting component 4, and the lifting component are provided. The movable plate 3 is provided with a flow pipe 1 on one side. One end of the flow pipe 1 is connected to a feeding pipe. A nozzle 2 is installed on the flow pipe 1. The spraying liquid can be transported into the flow pipe 1 through the feeding pipe. After flowing inside the flow pipe 1, it is finally atomized and sprayed out from the nozzle 2 to realize the spraying operation.

[0031] The other side of the movable plate 3 is mounted on the adjustment component 4. The adjustment component 4 is used to adjust the tilt angle and spraying direction of the nozzle 2. The upper end of the adjustment component 4 is provided with a lifting component. The operation of the lifting component can change the vertical height position and the front and back angle position of the adjustment component 4, so that spraying operations can be carried out on objects of different depths and directions.

[0032] The lifting assembly includes a movable rod 5, a transmission box 7, an output cylinder 8, and a servo motor 10. The transmission box 7 and the servo motor 10 are linearly arranged and mounted on the mounting plate 6. The output cylinder 8 is located at the upper end of the transmission box 7. One end of the movable rod 5 is connected to the adjustment assembly 4, and the other end of the movable rod 5, after passing through the mounting plate 6 and the transmission box 7, is connected to the output end of the output cylinder 8. When the lifting assembly is used to adjust the vertical position of the nozzle 2, the output cylinder 8 is activated. The output cylinder 8 outputs kinetic energy to push the movable rod 5 to move up and down inside the transmission box 7, thereby causing the adjustment assembly 4 mounted at one end of the movable rod 5 to move up and down, thus changing the height position of the nozzle 2 mounted on one side of the adjustment assembly 4. When it is necessary to adjust the front and rear angle position of the nozzle 2, the servo motor 10 is activated. The servo motor 10 outputs kinetic energy to the transmission box 7, causing the movable rod 5, which passes through the transmission box 7, to rotate, thus adjusting the front and rear angle position of the adjustment assembly 4 mounted at one end of the movable rod 5.

[0033] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the movable rod 5 is provided with a secondary bevel gear 11 on the part inside the transmission box 7, and the outer side of the movable rod 5 is meshed with the axial position of the secondary bevel gear 11; the output end of the servo motor 10 is provided with an output shaft 9, and a main bevel gear 12 is installed on the part of the output shaft 9 inside the transmission box 7, and the outer side of the main bevel gear 12 meshes with the outer side of the secondary bevel gear 11.

[0034] In an embodiment of this utility model, for example, when the output cylinder 8 is activated to adjust the vertical position of the movable rod 5, the output cylinder 8 can output kinetic energy to move the movable rod 5 up and down along the axis of the secondary bevel gear 11; and when the servo motor 10 is activated to output kinetic energy to drive the movable rod 5 to rotate, the servo motor 10 is activated, and the servo motor 10 outputs kinetic energy to drive the output shaft 9 to rotate. When the output shaft 9 rotates, it will drive the main bevel gear 12 to rotate. Since the outer side of the main bevel gear 12 meshes with the outer side of the secondary bevel gear 11, and the axis of the secondary bevel gear 11 meshes with the outer side of the movable rod 5, the rotation of the main bevel gear 12 will drive the secondary bevel gear 11 to rotate, and the rotation of the secondary bevel gear 11 will drive the movable rod 5 to rotate.

[0035] Please see Figure 1 and Figure 3In one embodiment of the present invention, the adjustment component 4 includes a drive cylinder 19 and a positioning plate 18. One side of the drive cylinder 19 is connected to one end of the movable rod 5, and one end of the positioning plate 18 is fixedly mounted on the side of the drive cylinder 19. The output end of the drive cylinder 19 is provided with a movable toothed rack 16, and the positioning plate 18 is provided with a positioning shaft 14 that is staggered vertically.

[0036] The movable plate 3 is equipped with a bushing 13 on one side, and a semi-toothed ring 15 is formed on the outer side of the bushing 13. The outer side of the semi-toothed ring 15 meshes with the outer side of the movable toothed row 16. The bushing 13 is rotatably mounted on the outer side of the positioning shaft 14 located at the upper end of the positioning plate 18 at the axial position. The lower end of the movable toothed row 16 is placed on the guide roller 17, and the guide roller 17 is rotatably mounted on the outer side of the positioning shaft 14 located at the lower end of the positioning plate 18 at the axial position.

[0037] In an embodiment of this utility model, when the adjustment component 4 is used to adjust the tilt angle of the nozzle 2 installed on one side of the movable plate 3, the drive cylinder 19 is activated, and the drive cylinder 19 outputs kinetic energy to push the movable toothed row 16 to move laterally.

[0038] Since the outer side of the movable toothed row 16 meshes with the outer side of the half toothed ring 15, and the lower end of the movable toothed row 16 is mounted on the guide roller 17, when the movable toothed row 16 moves laterally, it will drive the bushing 13 to rotate around the positioning shaft 14 located at the upper end of the positioning plate 18. When the bushing 13 rotates, it will drive the movable plate 3 mounted on one side of the bushing 13 to rotate, changing the tilt angle position of the nozzle 2 mounted on one side of the movable plate 3. At the same time, it will also drive the guide roller 17 to rotate around the positioning shaft 14 located at the lower end of the positioning plate 18, thus supporting and guiding the displacement of the movable toothed row 16.

[0039] Please see Figure 4 In one embodiment of the present invention, the nozzle 2 has a frustum-shaped structure. The nozzle 2 has a pinhole 21 for passing through an electrostatic needle in the middle. A plurality of uniform flow holes 22 for uniformly guiding the sprayed powder are arranged around the pinhole 21. The uniform flow holes 22 are evenly distributed on the nozzle 2.

[0040] By setting a frustum-shaped nozzle 2 at the liquid outlet of the electrostatic spray gun, and having several uniform flow holes 22 evenly distributed around the outer periphery of the nozzle 2, the powder sprayed by the electrostatic spray gun is evenly diffused, resulting in higher coating quality. Moreover, when the powder sprayed by the spray gun passes through the uniform flow holes 22, the powder is guided by the uniform flow holes 22, which helps to unblock the flow direction of the powder molecules and unify their movement direction, thereby improving the powder application rate.

[0041] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
