[0004] However, existing defoaming equipment for paint processing also has certain shortcomings. Most existing defoaming equipment for paint processing simply uses components such as fixed-position stirring blades to stir and defoam the paint. Due to factors such as the distribution range of the paint, simply using fixed-position stirring blades can easily lead to poor defoaming efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a defoaming device for coating processing, which solves the problem that existing defoaming devices for coating processing often simply use fixed-position stirring blades or other components to stir and defoam the coating. Due to factors such as the distribution range of the coating, simply using fixed-position stirring blades can easily lead to poor defoaming efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a defoaming device for coating processing, comprising a defoaming tank, an inlet pipe fixedly connected to the inner wall of the defoaming tank, an outlet pipe fixedly connected to the inner wall of the defoaming tank, a fixed rod fixedly connected to the inner wall of the outlet pipe, a driven rod rotatably connected to the inner wall of the fixed rod, a blade fixedly connected to the surface of the driven rod and located on the right side of the fixed rod, a mesh rod fixedly connected to the surface of the driven rod and located on the left side of the fixed rod, a scraper fixedly connected to the other end of the mesh rod, the scraper slidingly connected to the inner wall of the outlet pipe, and a defoaming mechanism provided on the defoaming tank.

[0007] Preferably, a limiting block is fixedly connected to the surface of the driven rod, and the limiting block is rotatably connected to the fixed rod. By setting the limiting block, the driven rod can be rotated and limited.

[0008] Preferably, multiple blades are provided, and the multiple blades are arranged in a ring array on the driven rod. By the arrangement of the blades, it can be ensured that when the high-speed fluid coating impacts it, the blades can drive the driven rod to rotate.

[0009] Preferably, multiple mesh rods are provided, and the multiple mesh rods are evenly distributed on the driven rod. By setting the mesh rods, the conveyed coating can be stirred and defoamed.

[0010] Preferably, the defoaming mechanism includes a servo motor. The servo motor is fixedly installed at the upper center of the defoaming tank lid. The output shaft of the servo motor is rotatably connected to the lid of the defoaming tank. A support column is fixedly connected to the output shaft of the servo motor. The support column is rotatably connected to the inner wall of the defoaming tank. A sliding groove is provided on the output shaft of the servo motor. A sliding plate is slidably connected to the inner wall of the sliding groove. A defoaming net is fixedly connected to the end face of the sliding plate. A submersible motor is installed on the output shaft of the servo motor through a connecting block. A screw is fixedly connected to the output shaft of the submersible motor. The screw is threadedly connected to the sliding plate. Driven by the servo motor, the sliding plate can rotate the defoaming net.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a servo motor to drive the output shaft to rotate, which allows the slide plate to rotate the defoaming net. With the help of a submersible motor, screw and other structures, the slide plate can drive the defoaming net to move, so that the defoaming net can move and rotate inside the defoaming tank to defoam the coating.

[0015] 2. This utility model, through the setting of the discharge pipe, can output and use the coating. With the suction action of devices such as the suction pump, the blades can withstand the impact of high-speed fluid, thereby causing the blades to drive the driven rod to rotate, which in turn drives the mesh bar and scraper to rotate, thus defoaming the conveyed coating and reducing the impact of bubbles.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5A limiting block 6 is fixedly connected to the surface of the driven rod 5. The limiting block 6 is rotatably connected to the fixed rod 4. The limiting block 6 can limit the rotation of the driven rod 5. Multiple blades 7 are arranged in a ring array on the driven rod 5. The blades 7 can drive the driven rod 5 to rotate when impacted by high-speed fluid coating. Multiple mesh bars 8 are evenly distributed on the driven rod 5. The mesh bars 8 can agitate and defoam the conveyed coating.

[0025] Please see Figure 1 , Figure 2 , Figure 4 The defoaming tank 1 is equipped with a defoaming mechanism 10, which includes a servo motor 101. The servo motor 101 is fixedly installed at the upper middle part of the lid of the defoaming tank 1. The output shaft of the servo motor 101 is rotatably connected to the lid of the defoaming tank 1. The output shaft of the servo motor 101 is fixedly connected to a support column 102, which is rotatably connected to the inner wall of the defoaming tank 1. The output shaft of the servo motor 101 has a sliding groove 103, and a sliding plate 104 is slidably connected to the inner wall of the sliding groove 103. The end of the sliding plate 104... A defoaming net 105 is fixedly connected to the surface. A submersible motor 106 is mounted on the output shaft of a servo motor 101 via a connecting block. A screw 107 is fixedly connected to the output shaft of the submersible motor 106. The screw 107 is threadedly connected to the slide plate 104. Driven by the servo motor 101, the slide plate 104 can rotate the defoaming net 105. In conjunction with the submersible motor 106, screw 107, and other structures, the defoaming net 105 can move to improve its defoaming efficiency.

[0026] Please see Figure 1 , Figure 2 , Figure 4 Four defoaming nets 105 are provided, and the four defoaming nets 105 are evenly distributed on the slide plate 104.

The submersible motor 106 is started to drive the output shaft to rotate, thereby driving the screw 107 to rotate. Under the threaded connection, the slide plate 104 can be driven to slide along the inner wall of the slide groove 103, thereby driving the defoaming net 105 to move, so that the defoaming net 105 rotates and moves at the same time, thereby improving the defoaming efficiency of the paint.

[0028] The discharge pipe 3 allows for the output of coatings. In conjunction with a suction pump and other devices, the coatings can be suctioned. Under the impact of the high-speed fluid, the blades 7 rotate, which in turn drives the driven rod 5 to rotate. When the driven rod 5 rotates, it drives the limiting block 6 to rotate along the surface of the fixed rod 4, ensuring the stability of the driven rod 5's rotation. This, in turn, drives the mesh bar 8 and scraper 9 to rotate, defoaming the coatings and reducing foaming problems during the coating transport process.
