Description

Technical Field

[0001] The utility model belongs to the technical field of electrostatic spraying, and in particular relates to an electrostatic spraying anti-sputtering mechanism. Background Art

[0002] Electrostatic spraying is a spraying method that uses a high-voltage electrostatic field to make negatively charged paint particles move in a direction opposite to the electric field and adsorb the paint particles on the surface of the workpiece. The electrostatic spraying equipment consists of a spray gun, a spray cup, and an electrostatic spraying high-voltage power supply. It has been widely used in the field of workpiece spraying. At present, the electrostatic spraying device lacks an effective anti-sputtering mechanism, and the paint is easy to splash out, affecting the working environment and causing a waste of paint resources. The anti-sputtering mechanism is inconvenient to disassemble and assemble, affecting its use.

[0003] In the prior art, a Chinese patent with a reference publication number of CN 218486301 U discloses an anti-sputtering mechanism for an electrostatic spraying device, including a protective frame, a reciprocating screw rod rotatably connected to the inner side of the protective frame, and a spraying mechanism is threadedly connected to the reciprocating screw rod, the spraying mechanism includes a sliding block threadedly connected to the reciprocating screw rod, and a mounting plate integrally formed on one side of the sliding block, and two symmetrically distributed clamps are installed on the mounting plate, and spray guns are fixed on both clamps, and an anti-sputtering protective cover is provided on the spray gun. The utility model can form an anti-sputtering treatment for the spray gun by arranging a protective cover on the spray gun and installing an anti-sputtering plate on a T-shaped track on one side of the protective frame to prevent splashed paint from affecting the on-site environment.

[0004] The comparative document provides an electrostatic spraying mechanism with an anti-sputtering structure, but when the above patent is performing electrostatic spraying operation, paint particles will be adsorbed on the reciprocating screw. As the use time increases, a thicker layer of paint will be adsorbed on the reciprocating screw, causing the reciprocating screw to lose its ability. The reciprocating screw has no protective ability, which in turn causes the mechanism to have low protective ability.

[0005] Therefore, an electrostatic spraying anti-sputtering mechanism is proposed. Utility Model Content

[0007] The utility model is implemented as follows: an electrostatic spraying anti-sputtering mechanism comprises: a fixed frame; a motor fixed to the outer wall of the fixed frame by bolts; a ball screw fixed to the output end of the motor; a movable platform fixed to the nut seat on the ball screw by a nut; a nozzle embedded in the outer wall of the movable platform; a protective cover fixed to the outer wall of the movable platform near the outer side of the nozzle by bolts; a first protective component arranged at the inner side of the fixed frame; wherein the first protective component comprises: a first bellows and a second bellows fixed between the inner wall of the fixed frame and the outer wall of the movable platform by adhesive bonding, the first bellows being located on one side of the second bellows; a guide block arranged at the top of the first bellows and the second bellows; and a guide rod arranged at a position on the inner wall of the fixed frame near one side of the ball screw.

[0008] An electrostatic spraying anti-sputtering mechanism also includes a second protective component arranged on the outer side wall of the movable platform; wherein the second protective component includes: a first baffle plate arranged at a side of the movable platform; a second baffle plate welded to the outer side wall of the first baffle plate; a fastening nut passing through the first baffle plate and the second baffle plate; and a threaded hole opened on the outer side wall of the movable platform.

[0009] Preferably, a guide hole for the guide rod to pass through is formed on one side outer wall of the guide block.

[0010] Preferably, the cross section of the protective cover is an isosceles trapezoidal structure.

[0011] Preferably, the first bellows and the second bellows are sleeved on the outside of the ball screw, and neither the first bellows nor the second bellows are in contact with the ball screw.

[0012] Preferably, the included angle between the first baffle and the second baffle is degrees.

[0013] Preferably, the fastening nut and the threaded hole are screwed together via threads.

[0014] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0015] The first bellows and the second bellows that can be stretched or compressed on the outside of the ball screw can effectively protect the ball screw to avoid the problem of paint particles being adsorbed on the ball screw and causing loss of power during electrostatic spraying, thereby ensuring smooth movement of the nozzle. The guide rod supports the guide block to avoid the first bellows and the second bellows from contacting the ball screw after deformation and causing damage to movement. The protection of the nozzle by the protective cover and the second protective assembly can achieve protection during the spraying process, reduce spray spattering, and can also be disassembled and assembled according to needs.

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The utility model embodiment provides an electrostatic spraying anti-sputtering mechanism, such as Figure 1-4As shown, it includes a fixed frame 1, a motor 2 is fixedly connected to the outer wall of one side of the fixed frame 1 by bolts, a ball screw 3 is fixedly connected to the output end of the motor 2, a nut seat on the ball screw 3 is fixedly connected to a moving platform 4 by a nut, a nozzle 5 is embedded in the outer wall of one side of the moving platform 4, a protective cover 6 is fixedly connected to the outer position of the outer wall of one side of the moving platform 4 near the nozzle 5 by bolts, the cross-section of the protective cover 6 is an isosceles trapezoidal structure, a first bellows 71 and a second bellows 72 in a first protective assembly 7 are fixed between the inner wall of the fixed frame 1 and the outer wall of the moving platform 4 by adhesive, the first bellows 71 is located on one side of the second bellows 72, and guide blocks 73 are arranged on the top of the first bellows 71 and the second bellows 72, and a guide rod 74 is welded to the inner wall of one side of the fixed frame 1 in the vertical direction near the ball screw 3.

[0025] It should be noted that, since the existing electrostatic spraying mechanism is performing electrostatic spraying operation, paint particles will be adsorbed on the reciprocating screw. As the use time increases, a thicker paint layer will be adsorbed on the reciprocating screw, causing the reciprocating screw to lose its ability. The reciprocating screw does not have protection ability, which causes the mechanism to have low protection ability. In this embodiment, the first bellows 71 and the second bellows 72 that can be stretched or compressed on the outside of the ball screw 3 can effectively protect the ball screw 3 to avoid the problem of paint particles being adsorbed on the ball screw 3 during the electrostatic spraying process and causing loss of ability, thereby ensuring smooth movement of the nozzle 5, and guiding and supporting the guide block 73 through the guide rod 74 to avoid the first bellows 71 and the second bellows 72 from contacting the ball screw 3 after deformation and causing damage to movement. The protection of the nozzle 5 by the protective cover 6 and the second protective assembly 8 can achieve protection during the spraying process and reduce spray sputtering. It can also be disassembled and assembled according to needs.

[0026] Specifically, in this embodiment, this scheme mainly includes a first protective component 7. When in use, the nozzle 5 is connected to the spray pipe of the electrostatic spraying equipment, and the motor 2 drives the ball screw 3 to rotate through its output end. The movable platform 4 on the ball screw 3 moves along a straight line to realize the reciprocating linear motion of the nozzle 5, thereby realizing large-area spraying. When the movable platform 4 moves, the movable platform 4 will squeeze or stretch the first bellows 71 and the second bellows 72. The guide blocks 73 on the first bellows 71 and the second bellows 72 move along the guide rod 74. The first bellows 71 and the second bellows 72 are deformed to adapt to the movement of the movable platform 4, which can not only protect the ball screw 3, but also prevent the first bellows 71 and the second bellows 72 from contacting the ball screw 3 after deformation, causing damage to the movement.

[0027] The utility model embodiment provides an electrostatic spraying anti-sputtering mechanism, such as Figure 1-3 and Figure 5As shown, it includes a moving platform 4, and a first baffle 81 in the second protective component 8 is arranged at one side of the moving platform 4. A second baffle 82 is welded on one side outer wall of the first baffle 81, and the angle between the first baffle 81 and the second baffle 82 is 90 degrees. A fastening nut 83 passes through one side outer wall of the first baffle 81 and the second baffle 82, and a threaded hole 84 is opened on one side outer wall of the moving platform 4. The fastening nut 83 and the threaded hole 84 are screwed together by threads.

[0028] Specifically, in this embodiment, this scheme mainly includes a second protective component 8. When in use, the fastening nut 83 is passed through the first baffle plate 81 and the second baffle plate 82 and then screwed into the threaded hole 84 to achieve the installation of the first baffle plate 81 and the second baffle plate 82 on the outer wall of the movable platform 4. The first baffle plate 81 and the second baffle plate 82 can be used to achieve protection during the spraying process and reduce spraying splashing. It can also be disassembled and assembled according to needs.

[0029] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a guide hole is provided on one side outer wall of the guide block 73 for the guide rod 74 to pass through.

[0030] In this embodiment, the guide block 73 can be moved along the guide rod 74 to achieve guiding support for the first bellows 71 and the second bellows 72, thereby preventing the first bellows 71 and the second bellows 72 from being damaged by contact with the ball screw 3 after deformation.

[0031] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the first bellows 71 and the second bellows 72 are sleeved on the outside of the ball screw 3 , and the first bellows 71 and the second bellows 72 are not in contact with the ball screw 3 .

[0032] In this embodiment, it is possible to avoid the first bellows 71 and the second bellows 72 being damaged in movement due to contact with the ball screw 3 after deformation.
