Description

Technical Field

[0001] This utility model belongs to the field of electrostatic spraying technology, specifically relating to an auxiliary device for an electrostatic spraying gun. Background Technology

[0002] Electrostatic spraying, also known as powder coating, involves using powder spraying equipment (electrostatic powder coating machine) to apply powder coating to the surface of a workpiece. Under the influence of electrostatics, the powder adheres evenly to the workpiece surface, forming a powdery coating. This powdery coating is then baked at high temperature to achieve leveling and curing, resulting in a final coating with varying effects (depending on the type of powder coating). Currently, manufacturers generally use large-scale powder spraying equipment for automated powder coating. However, for small batches of products with special shapes, manual hand-held spray gun operation is still necessary. Manual spray gun operation is more flexible and can meet the coating requirements of complex workpieces. However, the spray gun, connected to a feed tube, has a certain weight. In addition to the weight of the spray gun, the operator must also overcome the weight and inconvenience of the feed tube. Furthermore, the spraying process may require changing spray guns to spray different colors and types of powder, and the lack of effective coordination between different feed tubes further affects the operator's experience in operating the spray gun. Utility Model Content

[0003] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an auxiliary device for electrostatic spraying spray gun, including a column, a base fixedly connected to the lower end of the column, and several rotating telescopic arms installed sequentially from bottom to top on the upper end of the column. Each rotating telescopic arm includes a fixed tube and a telescopic section. One end of the fixed tube is rotatably mounted on the column, and one end of the telescopic section is inserted into the fixed tube from the other end of the fixed tube. A spray gun hook is installed at the other end of the telescopic section. Several functional hooks are sequentially installed on the fixed tube and the telescopic section, and some of the functional hooks are equipped with automatic retractable cord retractors.

[0004] As a preferred embodiment of the above technical solution, the column includes a large-diameter section and a small-diameter section. The lower end of the small-diameter section is fixedly connected to the upper end of the large-diameter section, and the lower end of the large-diameter section is fixedly connected to the base. One end of the fixing tube is fixedly connected to a sleeve, which is fitted onto the small-diameter section and connected to the small-diameter section through a bearing. The inner diameter of the sleeve is smaller than the diameter of the large-diameter section.

[0005] As a preferred embodiment of the above technical solution, a keyway is provided on the small diameter section, and a key is fixed on the inner ring of the bearing, with the key extending into the keyway.

[0006] As a preferred embodiment of the above technical solution, a number of pipe hooks are fixedly connected to the large-diameter section.

[0007] As a preferred embodiment of the above technical solution, one side of the fixed tube is provided with a long groove that connects to the inside of the fixed tube, a limit bolt is inserted into the long groove, and the telescopic section is provided with a threaded hole for the limit bolt to be screwed in.

[0008] As a preferred embodiment of the above technical solution, the outer surface of the rotating telescopic arm is coated with paint, and the paint color is different on different rotating telescopic arms, and the color of the paint on the rotating telescopic arm corresponds to the color of the powder sprayed by the spray gun.

[0009] The beneficial effects of this utility model are: the electrostatic spraying spray gun auxiliary device of this utility model can simultaneously assist multiple spray guns in powder spraying operations.

[0015] like Figure 1-2 As shown, the electrostatic spraying spray gun auxiliary device includes a column, with a base 1 fixedly connected to the lower end of the column. Several rotating telescopic arms are sequentially installed from bottom to top on the upper end of the column. Each rotating telescopic arm includes a fixed tube 2 and a telescopic section 3. One end of the fixed tube 2 is rotatably mounted on the column, and one end of the telescopic section 3 is inserted into the fixed tube 2 from the other end. A spray gun hook 4 is installed at the other end of the telescopic section 3. Several functional hooks 5 are sequentially installed on the fixed tube 2 and the telescopic section 3. Some of the functional hooks 5 are equipped with automatic retractable coil retractors 6. When the spray gun is not in use, it is hung on the spray gun hook 4, and the paint supply tube on the spray gun is suspended by the automatic retractable coil retractor 6, leaving a certain amount of slack. When in use, the spray gun is removed, and the supply tube can be pulled with minimal force. The spray gun can be used for spraying at any angle and position without needing to hold the supply tube. Multiple spray guns can be used depending on the spraying needs, with different spray guns hung on different rotating telescopic arm spray gun hooks 4 for easy selection.

[0016] Furthermore, the column includes a large-diameter section 7 and a small-diameter section 8. The lower end of the small-diameter section 8 is fixedly connected to the upper end of the large-diameter section 7, and the lower end of the large-diameter section 7 is fixedly connected to the base 1.

The inner diameter of the sleeve 9 is smaller than the diameter of the large-diameter section 7.

[0017] Furthermore, a keyway 10 is provided on the small-diameter segment 8, and a key 11 is fixed on the inner ring of the bearing, extending into the keyway 10. The rotating telescopic arm is installed as needed. The key 11 cooperates with the keyway 10 to prevent the inner ring of the bearing from sliding relative to the small-diameter segment 8, ensuring the smooth rotation of the rotating telescopic arm.

[0018] Furthermore, several pipe hooks 12 are fixedly connected to the large-diameter section 7. The feed pipe of the spray gun can be wound around the large-diameter section 7 and locked into the pipe hooks 12 for regularization and fixation.

[0019] Furthermore, one side of the fixed tube 2 is provided with a long groove 13 that connects to the inside of the fixed tube 2. A limiting bolt 14 is inserted into the long groove 13, and the telescopic section 3 is provided with a threaded hole 15 for the limiting bolt 14 to be screwed in. The limiting bolt 14 can prevent the telescopic section 3 from falling out of the fixed tube 2, and can also fix the position of the telescopic section 3 after the length is adjusted.

[0020] Furthermore, the outer surface of the rotating telescopic arm is coated with paint, and the paint color varies on different rotating telescopic arms, corresponding to the color of the powder sprayed from the spray gun. The spray gun is hung on the spray gun hook 4 of the corresponding rotating telescopic arm for easy selection of the appropriate spray gun.

[0021] It is worth mentioning that the technical features such as the spray gun involved in this utility model patent application should be regarded as prior art.
