Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically to a spraying device adapted to workpieces of different shapes. Background Technology

[0002] Compared to traditional processes, electrostatic powder coating involves spraying powder onto a workpiece, which then cures to form a fine coating film on the workpiece surface, resulting in a smooth finished product and enhancing its perceived quality.

[0003] For example, Chinese patent CN220091746U discloses an electrostatic spraying coating equipment. The equipment includes a coating chamber. In the coating chamber, a high-voltage DC electric field causes the atomized paint particles to become negatively charged and adsorbed onto the positively charged substrate surface to achieve spraying.

[0004] However, for some boxes with different bottom shapes and concave sides, there are often blind spots in the spraying process. If the box is simply suspended during spraying, it is difficult to spray the outer edge of the box completely.

[0005] Based on this, the present invention designs a spraying device that is adaptable to workpieces of different shapes to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a spraying device that is adaptable to workpieces of different shapes.

The support assembly is mounted on the rotating rods located on the upper side of the two sets of parallel rotating structures.

[0012] Furthermore, the support assembly includes connecting rods, a movable block, and a support block. The middle parts of the two rotating rods are rotatably connected to one end of a connecting rod, and the other ends of the two connecting rods are rotatably connected to the same movable block. A support block with a support for the top of the polygonal box is rotatably mounted on the upper side of the movable block.

The upper end of the square rod is fixedly connected to the bottom of the moving block, and the lower end of the square rod passes through the support frame, the rotating block, and the turntable before being fixedly installed with the fixing plate. The spring is sleeved on the outside of the square rod, with the upper end of the spring fixedly connected to the moving block and the lower end of the spring fixedly connected to the support frame.

[0015] Furthermore, the spraying mechanism includes a spraying component and a rotating component, which are mounted on a base. The spraying component is located on the side of the turntable, and the rotating component is located below the turntable.

[0016] Furthermore, the spraying assembly includes a support platform, a second baffle, a first cylinder, and a spray gun. The support platform is fixedly mounted on a base, and an arc-shaped second baffle is fixedly mounted on the side of the support platform. A through groove is opened in the middle of the second baffle. The first cylinder is fixedly mounted on the support platform, and a spray gun is fixedly mounted on the output end of the first cylinder. The nozzle of the spray gun is tilted downward and passes through the through groove in the middle of the second baffle.

The rotating body allows for comprehensive spraying of the outer surface of the polygonal box, resulting in more uniform spraying and ensuring the stability of the polygonal box during the spraying process, preventing it from falling off. The cooperation between the first baffle and the spraying mechanism prevents spray powder from scattering to other areas. During the spraying process, the completed polygonal box can be removed from the first station, and the polygonal box to be sprayed can be fixed to the main structure. After spraying is completed, the turntable moves the sprayed polygonal box, while the polygonal box placed at the first station rotates to the second station for continued spraying. This enables continuous loading and unloading of materials for spraying, improving spraying efficiency. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-2 A spraying device adapted to workpieces of different shapes, including a base 1;

[0030] The base 1 has four workstations arranged in a clockwise direction, numbered one to four, with the first workstation located directly in front;

[0031] A rotatable turntable 2 is installed in the middle of the base 1; a first baffle 21 for separating and accommodating different polygonal boxes 6 is fixedly installed on the upper side of the turntable 2; a spraying mechanism 3 for spraying the polygonal boxes 6 is installed on the base 1 at the second work station.

Multiple sets of main structures 51 are evenly installed in a circular array on the turntable 2. The main structure 51 is equipped with a locking component 52 for locking the main structure 51. The base 1 is equipped with an unlocking component 53 for unlocking the main structure 51 at the first work station.

[0033] In this embodiment, when the spraying device adaptable to workpieces of different shapes is working normally, at the first station, the unlocking component 53 is activated to release the lock of the main structure 51, so that the main structure 51 is in a retracted state, which facilitates the installation of the polygonal box 6; the opening of the polygonal box 6 is facing downward, and the main structure 51 supports the inner top and two diagonals of the polygonal box 6, so that the main structure 51 can adapt to polygonal boxes 6 with different bottom shapes; then the unlocking component 53 is reset, and the main structure 51 is automatically locked by gravity and the locking component 52, and the turntable 2 drives the polygonal box 6 to rotate to the second station through the main structure 51; while the spraying mechanism 3 sprays the polygonal box 6, the spraying mechanism 3, through the main structure The rotating mechanism 51 and locking component 52 drive the polygonal box 6 to rotate, enabling comprehensive spraying of the outer side of the polygonal box 6. This results in more uniform spraying and keeps the polygonal box 6 stable during the spraying process, preventing it from falling off. Simultaneously, the cooperation between the first baffle 21 and the spraying mechanism 3 prevents spray powder from scattering to other areas. During the spraying process, the completed polygonal box 6 can be removed from the first station and the polygonal box 6 to be sprayed can be fixed to the main structure 51. After spraying is completed, the turntable 2 moves the completed polygonal box 6, while the polygonal box 6 placed at the first station rotates to the second station for continued spraying. This achieves continuous loading and unloading of materials for spraying, improving spraying efficiency.

The spring 522 is sleeved on the outside of the square rod 521. The upper end of the spring 522 is fixedly connected to the moving block 516, and the lower end of the spring 522 is fixedly connected to the support frame 512. The square rod 521 is slidably connected to the rotating block 511 and to the support frame 512.

[0038] The side of the fixing plate 523 is provided with anti-slip grooves;

[0039] The unlocking component 53 includes a second cylinder 531 and a pusher block 532. The second cylinder 531 is fixedly installed on the base 1, and the output end of the second cylinder 531 is fixedly installed with a pusher block 532 for pushing the fixed plate 523.

[0040] The spraying mechanism 3 includes a spraying component 31 and a rotating component 32. The spraying component 31 and the rotating component 32 are mounted on the base 1. The spraying component 31 is located on the side of the turntable 2, and the rotating component 32 is located below the turntable 2.

[0041] The spraying assembly 31 includes a support platform 311, a second baffle 312, a first cylinder 313, and a spray gun 314. The support platform 311 is fixedly installed on the base 1. An arc-shaped second baffle 312 is fixedly installed on the side of the support platform 311. A through groove is opened in the middle of the second baffle 312. The first cylinder 313 is fixedly installed on the support platform 311. The output end of the first cylinder 313 is fixedly installed with a spray gun 314.

[0043] Spray gun 314 is a mature technology in this field, and powder electrostatic spray guns such as those disclosed in Chinese patent CN113198630A can be used.

[0044] In this embodiment, when the spraying mechanism 3 and the self-locking support structure 5 are working normally, the second cylinder 531 drives the push block 532 to move, the push block 532 pushes the fixed plate 523 to move upward, thereby pushing the square rod 521 to move upward. The square rod 521 drives the moving block 516 to move upward, thereby driving the rotating rod 513 to rotate upward through the connecting rod 515, so that the side support rod 514 is retracted, making it easier to place the polygonal box 6; the spring 522 is stretched; the inner top of the polygonal box 6 is supported by the support block 517, so that the side support rod 514 is aligned with the two opposite corners inside the polygonal box 6. Then the second cylinder 531 drives the push block 532 to reset, the spring 522 resets, and the fixed plate 523 and the square rod 521 move downward under the action of gravity and the reset force of the spring 522, driving the moving block 516 to move downward. The connecting rod 515 and the rotating rod 513 drive the side support rod 514 to expand to both sides to support the two opposite corners of the inner side of the polygonal box 6. After the turntable 2 moves the polygonal box 6 to the second station, the first cylinder 313 drives the spray gun 314 to move and spray the polygonal box 6. At the same time, the fixed plate 523 moves between the anti-slip plate 324, and the pneumatic clamp 323 drives the anti-slip plate 324 to clamp the fixed plate 523. Then, the motor 321 drives the fixed plate 523 to rotate through the rotary table 322, the pneumatic clamp 323 and the anti-slip plate 324, thereby driving the rotating block 511 to rotate through the square rod 521. Thus, the polygonal box 6 is rotated through the support frame 512, the rotating rod 513 and the side support rod 514. Spraying continues during the rotation of the polygonal box 6 to make the spraying more uniform.
