Description

Technical Field

[0001] This utility model belongs to the technical field of spray painting equipment, and in particular relates to a rotating automatic spray painting device. Background Technology

[0002] A spray painting device is a device used to spray paint (such as paint, varnish or other liquid coatings) onto the surface of an object. It mixes paint with air through a spray gun or nozzle to form a spray-like fluid, which is then sprayed onto the object to be coated. The working principle of a spray painting device typically involves the use of compressed air or other gases to propel the paint from a container and distribute it evenly on the target surface in the form of tiny droplets through a nozzle. These devices are widely used in industries such as industry, automobiles, furniture, and construction, and can achieve efficient and precise coating effects.

[0003] In existing painting equipment, the workpiece is usually painted one side at a time. This method requires rotating the workpiece to adjust its angle before painting the next side. Since the position of the spray gun is usually fixed, it cannot be flexibly adjusted with the rotation of the workpiece. The workpiece needs to be rotated multiple times during painting to ensure that each side is evenly coated with paint, which increases the complexity of the operation. Since there may be a certain time interval or angle error during the rotation of the workpiece, it is easy to cause uneven distribution of paint during the spraying process, which in turn affects the quality of the final coating.

[0004] To address these issues, we provide a rotating automatic spray painting device. Utility Model Content

[0005] The purpose of this invention is to provide an automatic rotating spray painting device, which solves the problem that existing spray painting devices cannot automatically rotate and spray paint on workpieces by means of the cooperation of the rotating component and the limiting component.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an automatic rotary spray painting device, comprising a worktable, a bracket fixedly connected to one side of the top of the worktable, and a drive box fixedly connected to the other side of the top of the worktable; a rotary assembly is provided on the top of the worktable, the rotary assembly including a rotating rod, the rotating rod being movably connected to the inner cavity of the worktable, one end of the rotating rod being fixedly connected to a placement plate, a reciprocating screw being movably connected to the inner cavity of the drive box, a sliding sleeve being threadedly connected to the surface of the reciprocating screw, and a vertical spray gun being fixedly connected to one side of the sliding sleeve; a limit assembly is provided at the bottom of the bracket, the limit assembly including a cylinder, the cylinder being fixedly connected to one side of the top of the bracket, a movable sleeve being movably connected to the free end of the cylinder, and a limit plate being fixedly connected to the bottom of the movable sleeve.

[0008] The present invention is further configured such that a driven plate is fixedly connected to one side of the surface of the limiting plate, a reverse sliding sleeve is fixedly connected to one side of the bottom of the driven plate, and one side of the inner cavity of the driven plate and the inner cavity of the reverse sliding sleeve are both slidably connected to the surface of the reciprocating screw.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model uses a motor-driven reciprocating screw to enable the sliding sleeve to move back and forth on its surface, thereby allowing the position of the vertical spray gun to be adjusted in real time. The active belt pulley drives the driven belt pulley to rotate, which in turn drives the rotating rod to rotate. The rotating rod enables the placement tray to rotate, allowing the workpiece placed on the placement tray to rotate during the spraying process.

[0027] Specifically: A controller is fixedly connected to one side of the bracket 2. The controller can control the motor 20, the infrared heating lamp 19, the cylinder 9 and the solenoid valve. One end of the rotating rod 4 is movably connected to the bottom of the inner cavity of the worktable 1 through a rotating shaft, and the other end is fixed to the bottom of the placement plate 5. A limit rod is fixedly connected to one side of the inner cavity of the drive box 3. The surface of the limit rod is slidably connected to one side of the inner cavity of the sliding sleeve 7 and one side of the inner cavity of the driven plate 12. The vertical spray gun 8 can ensure that the paint is evenly distributed in the vertical direction, avoiding uneven coating or paint accumulation. The movable sleeve 10 allows the top of the limit plate 11 to be movably connected to the free end of the cylinder 9.

[0028] Example 2, please refer to Figure 1-5 Based on Embodiment 1, a driven plate 12 is fixedly connected to one side of the surface of the limiting plate 11, and a reverse sliding sleeve 13 is fixedly connected to one side of the bottom of the driven plate 12. Both the inner cavity of the driven plate 12 and the inner cavity of the reverse sliding sleeve 13 are slidably connected to the surface of the reciprocating screw 6. A paint storage tank 14 is fixedly connected to one side of the top of the worktable 1. A paint inlet pipe 15 is connected to one side of the top of the paint storage tank 14. One end of the paint inlet pipe 15 is connected to the input end of the vertical spray gun 8. A solenoid valve is installed on the surface of the paint inlet pipe 15. A drive pulley 1 is fixedly connected to one side of the surface of the reciprocating screw 6. 6. A driven pulley 17 is fixedly connected to one side of the rotating rod 4. The driving pulley 16 and the driven pulley 17 are connected by belt drive. A bearing plate 18 is fixedly connected to one side of the bracket 2.

The surface of the sliding sleeve 7 is slidably connected to the inner cavity of the sliding groove. A circular groove is opened on the top of the worktable 1. The surface of the placement plate 5 is movably connected to the inner cavity of the circular groove.

[0029] Specifically: the reverse sliding sleeve 13 can change the direction of movement when the sliding sleeve 7 contacts it, thereby automatically adjusting the space moved by the vertical spray gun 8 to follow the height of the workpiece. One end of the reciprocating screw 6 extends into the inner cavity of the worktable 1 and is movably connected to the bottom side of the inner cavity of the worktable 1 through a rotating shaft.

[0030] The working principle of this utility model is as follows: When it is necessary to automatically spray paint the workpiece, the workpiece is first placed in the placement tray 5, and then the cylinder 9 is started by the controller. The cylinder 9 drives the movable sleeve 10 to move, and the movable sleeve 10 drives the limiting plate 11 to move. The limiting plate 11 moves to limit the top of the workpiece. When the limiting plate 11 moves, it can drive the reverse sliding sleeve 13 on the bottom side of the driven plate 12 to move, so that when the sliding sleeve 7 moves on the surface of the reciprocating screw 6, the paint sprayed by the vertical spray gun 8 can be sprayed on the surface of the workpiece, and the vertical spray gun 8 can avoid spraying the paint on the workpiece.

[0031] Next, the solenoid valve and motor 20 are started simultaneously. The solenoid valve draws the paint in the paint tank 14 through the paint inlet pipe 15 into the vertical spray gun 8, and sprays it onto the surface of the workpiece. The motor 20 drives the bidirectional lead screw to rotate, which in turn drives the sliding sleeve 7 to move back and forth, thereby causing the vertical spray gun 8 to move back and forth to ensure uniform painting of the workpiece surface. At the same time, the bidirectional lead screw drives the drive pulley 16 to rotate, which in turn drives the driven pulley 17 to rotate, which in turn drives the rotating rod 4 to rotate, which in turn drives the placement plate 5 to rotate, which in turn drives the workpiece to rotate. As the workpiece rotates, the vertical spray gun 8 moves up and down back and forth to ensure uniform painting of the workpiece.

[0032] After the painting is finished, the solenoid valve is closed, the motor 20 continues to work, and the infrared heating lamp 19 is turned on to quickly dry the surface of the workpiece, so that the workpiece can be quickly taken out from the placement tray 5, thereby improving the painting efficiency.
