Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, specifically to a workpiece surface anti-corrosion coating equipment. Background Technology

[0002] When producing workpieces, corrosion prevention requires spraying corrosion inhibitors, such as anti-corrosion paint, onto their surfaces. The conventional spraying method involves conveying the workpieces on an assembly line and spraying them simultaneously. However, this method is fixed, often resulting in thicker coatings near the spray nozzle and thinner coatings or even no coating at all. This presents certain problems. Therefore, a workpiece surface corrosion inhibitor coating equipment is proposed. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows:

[0005] A workpiece surface anti-corrosion coating equipment includes a conveying mechanism and a spraying mechanism. The conveying mechanism includes a support frame, a conveyor belt mounted on the support frame, a rotating shaft fixedly connected to the middle of the conveyor belt, a turntable rotatably connected to the top of the rotating shaft, and a limiting rack meshing with the side of the turntable. The spraying mechanism includes a support plate mounted on the outside of the limiting rack, a vertical plate mounted on the upper part of the support plate, an injection pipe connected to the outside of the vertical plate, a nozzle communicating with the injection pipe, and a top plate fixed to the top of the vertical plate.

[0006] Preferably, the outer side of the limiting rack is fixedly connected to the support frame, and a support block mounted on the support frame is provided below the limiting rack.

[0007] Preferably, the conveyor belt is mounted on the middle of the support frame, and the middle of the support frame is provided with rollers for driving the conveyor belt to move.

[0008] Preferably, the bottom end of the injection pipe is connected to a connector through the support plate, and the connector is externally connected to the conveying tank.

[0009] Preferably, the top of the nozzle is fixed to the bottom of the top plate, and the number of nozzles is in groups of two, with the spraying direction of each group of nozzles pointing towards the center of the turntable.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0011] In this invention, a rotating shaft is set on the conveyor belt to connect the turntable, and the turntable meshes with the limiting rack. Therefore, when the turntable moves forward, it will rotate, thereby driving the workpiece on it to rotate. At this time, the two sets of four spray nozzles can spray the workpiece evenly without uneven spraying, thus improving the practicality of the device. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0018] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a workpiece surface anti-corrosion coating device.

[0019] Example:

[0020] Combination Figure 1-2 As shown, this utility model provides a workpiece surface anti-corrosion coating equipment, including a conveying mechanism and a spraying mechanism. The conveying mechanism includes a support frame 110, a conveyor belt 120 disposed on the support frame 110, a rotating shaft 130 fixedly connected to the middle of the conveyor belt 120, a turntable 140 rotatably connected to the top of the rotating shaft 130, and a limiting rack 150 meshing with the side of the turntable 140. The outer side of the limiting rack 150 is fixedly connected to the support frame 110, and a support block mounted on the support frame 110 is disposed below the limiting rack 150. The conveyor belt 120 is mounted on the middle of the support frame 110, and a support block is disposed on the middle of the support frame 110. The rollers that drive the conveyor belt 120 to move, the spraying mechanism includes a support plate 210 installed on the outside of the limiting rack 150, a vertical plate 220 installed on the upper part of the support plate 210, an injection pipe 240 connected to the outside of the vertical plate 220, a nozzle 260 connected through the injection pipe 240, and a top plate 250 fixed to the top of the vertical plate 220. The bottom end of the injection pipe 240 passes through the support plate 210 and is connected to a connector 230. The connector 230 is connected to a material tank. The top of the nozzle 260 is fixed to the bottom of the top plate 250, and the number of nozzles 260 is in groups of two. The spraying direction of a group of nozzles 260 is towards the center of the turntable 140.

[0021] Specifically, the spraying liquid is delivered to the spray head 260 through the injection pipe 240 for spraying, ensuring the foundation of the spraying. Furthermore, the use of two spray heads 260 spraying in opposite directions ensures comprehensive spraying of the workpiece, preventing incomplete spraying. At the same time, the turntable 140, in conjunction with the limiting rack 150, enables the workpiece to rotate during movement, achieving a more uniform spraying method in conjunction with the spray head 260, thus improving the practicality of the device.

[0022] The working principle and usage process of this utility model are as follows: First, place the workpiece to be sprayed on the turntable 140, start the conveyor belt 120 to drive the turntable 140 to move. Since one side of the turntable 140 is engaged with the limiting rack 150, it will rotate during the movement. At this time, the spray nozzle 260 starts spraying. The workpiece is sprayed during the movement. Finally, the device can be inspected regularly.

[0023] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
