Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and in particular to an electrostatic rotary cup type low-overspray environmentally friendly spraying device. Background Technology

[0002] The electrostatic rotary cup low-overspray spray gun is a high-efficiency and environmentally friendly spraying equipment that combines electrostatic spraying technology with the high-speed atomization principle of rotary cup. It is mainly used in the field of industrial coating. Its core advantage lies in the fact that through the dual effects of electrostatic adsorption and precision atomization, it can significantly reduce the amount of paint overspray, while improving the uniformity of the coating and the material utilization rate, which meets the needs of modern manufacturing industry for environmental protection and cost control.

[0003] A search revealed that Chinese patent CN206104206U discloses a handheld electrostatic rotary cup spray gun. Addressing the issue that the high-speed rotation of the rotary cup during use could easily cause it to collide with other objects or operators, resulting in unnecessary damage, a safety cover is incorporated. This cover protects the front end of the spray gun, preventing accidental contact with people or other products due to the high-speed rotation of the spray gun's front end. Furthermore, since the atomized paint sprayed from the spray gun is charged, the safety cover must be made of insulating material to ensure that the atomized paint does not adhere to the cover but is instead sprayed directly onto the product being treated.

[0004] While the aforementioned spray guns are convenient for blocking atomized paint, existing spray guns are generally divided into handheld and single-piece spray guns mounted on robotic arms. The handheld spray gun's handle is usually fixed to the spray gun, resulting in a fixed angle for the spray gun. When spraying complex workpieces, such as the curved surface of a car bumper, the fixed handle may limit the angle between the spray gun and the workpiece, leading to uneven coating. Furthermore, when working in confined spaces, the fixed handle may not be able to get close to the workpiece due to its non-adjustable angle and length, requiring multiple adjustments to the spray gun position or raising the arm, which reduces work efficiency.

[0007] As a further description of the above technical solution: Limiting blocks are fixedly connected to both sides of the inner column, and limiting grooves are opened on both sides of the inner wall of the outer shell. The limiting blocks are slidably connected inside the limiting grooves.

[0008] As a further description of the above technical solution: The outer shell is provided with multiple anti-slip strips, and the inner shell is rotatably connected with a screw, one end of which is fixedly connected to a knob.

[0009] As a further description of the above technical solution: A rotating block is hinged to one side of the connecting block, and a lead screw is rotatably connected to one side of the rotating block. A knob is fixedly connected to one end of the lead screw, and the lead screw is threaded inside the connecting frame.

[0010] As a further description of the above technical solution: The inner wall of the mounting block is provided with a separation component, which includes a plug rod.

[0018] As attached Figure 1-9 As shown, one embodiment of this utility model is provided: an electrostatic rotary cup type low-overspray environmentally friendly spraying device, including an electrostatic rotary cup spray gun 1, and a holding component is provided below the electrostatic rotary cup spray gun 1; The grip assembly includes a mounting block 2, which is positioned below the electrostatic rotary cup spray gun 1. A connecting frame 3 is fixedly connected to one side of the mounting block 2. A groove is formed on the lower surface of the mounting block 2, and a slider 24 is slidably connected inside the groove. A connecting frame 23 is fixedly connected to the lower surface of the slider 24. The width of the slider 24 is smaller than the width of the connecting frame 23. A connecting block 4 is hinged inside the connecting frame 23 to facilitate simultaneous connection with the inner column 5 and the rotating block 13. An inner column 5 is fixedly connected to the lower surface of the connecting block 4 for adjusting the height of the electrostatic rotary cup spray gun 1. A threaded groove 6 is formed inside the inner column 5 to match the screw 12. A shell 8 is slidably connected to the outside of the inner column 5 for easy gripping.

[0019] As attached Figure 4 As shown, limit blocks 7 are fixedly connected to both sides of the inner column 5, which limit the movement of the inner column 5.

[0020] As attached Figure 5 As shown, both sides of the inner wall of the outer shell 8 are provided with limiting grooves 9 for sliding of the limiting block 7. The limiting block 7 is slidably connected inside the limiting groove 9. Multiple anti-slip strips 10 are provided on the outside of the outer shell 8 to improve the grip anti-slip performance. A screw 12 is rotatably connected inside the outer shell 8. A knob 11 is fixedly connected to one end of the screw 12 to facilitate rotating the screw 12 to drive the inner column 5 to move.

[0021] As attached Figure 3 As shown, a rotating block 13 is hinged to one side of the connecting block 4, and a lead screw 14 is rotatably connected to one side of the rotating block 13. A knob 15 is fixedly connected to one end of the lead screw 14 to facilitate rotating the lead screw 14 to push the rotating block 13.

[0022] As attached Figure 6 As shown, the lead screw 14 is threaded into the inside of the connecting frame 3. The inner wall of the mounting block 2 is provided with a separation component, which includes a plug rod 16 for easy insertion into the insert frame 18. The plug rod 16 is fixedly connected to the inner wall of the mounting block 2. The plug rod 16 has a connecting groove 17 inside for easy sliding insertion of the locking rod 21.

[0023] As attached Figure 7 As shown, a frame 18 is fixedly connected to the lower surface of the electrostatic rotary cup spray gun 1. Through holes 19 are provided on both sides of the frame 18 to facilitate the insertion of the locking rod 21. An installation sleeve 20 is fixedly connected to one side of the frame 18 for the installation of the bolt 22.

[0024] As attached Figure 3 As shown, a locking rod 21 is inserted into the two through holes 19 and the connecting groove 17 to facilitate the locking of the rod 16 and the frame 18. One end of the locking rod 21 has a threaded hole, and a bolt 22 is threaded inside the threaded hole. The bolt 22 is slidably connected inside the mounting sleeve 20 to facilitate the locking rod 21.

[0025] Working principle: When holding the electrostatic rotary cup spray gun 1, the angle of the electrostatic rotary cup spray gun 1 needs to be adjusted. To spray the side of the workpiece, the angle is adjusted to be smaller. Then, turn the knob 15, which drives the lead screw 14 to rotate. When the lead screw 14 rotates, it will rotate on one side of the rotating block 13, which will cause the rotating block 13 to move laterally. When the rotating block 13 moves, it will push the connecting block 4 to rotate. When the connecting block 4 is pushed, it will cause the connecting block 4 to rotate inside the connecting frame 23, which will cause the slider 24 to slide inside the groove. The angle between the slider 24 and the electrostatic rotary cup spray gun 1 will become smaller, which will facilitate spraying the side of the workpiece away from the operator. Pulling the rotating block 13 will make the angle larger, which can be adjusted as needed. When adjusting the grip height, turn knob 11 to drive screw 12 to rotate. Under the connection of threaded groove 6, the inner column 5 slides inside the outer shell 8. At this time, the limiting block 7 will slide inside the limiting groove 9, which facilitates the adjustment of the distance between the grip outer shell 8 and the electrostatic rotary cup spray gun 1. When in use, connect the electrostatic rotary cup spray gun 1 to the paint spray pipe and start the electrostatic rotary cup spray gun 1 to spray. When the electrostatic rotary cup spray gun 1 is not handheld and needs to be installed on the machine, to disassemble the holding assembly, first unscrew the bolt 22 from the threaded hole of the locking rod 21 to release the locking rod 21 from its limit. Then slide the locking rod 21 out from the inside of the connecting groove 17 to release the insertion rod 16 from its limit. Slide the insertion rod 16 and the insertion frame 18 to separate them, making it easier to disassemble the electrostatic rotary cup spray gun 1 from the holding assembly. This makes the electrostatic rotary cup spray gun 1 an independent unit, which is convenient for installation on the machine.
