Description

Technical Field

[0001] This utility model relates to the field of steel pipe powder coating technology, specifically a steel pipe powder coating device. Background Technology

[0002] The working principle of powder coating is to charge plastic powder through a high-voltage electrostatic device. Under the action of the electric field, the coating is sprayed onto the surface of the workpiece. The powder is evenly adsorbed on the surface of the workpiece to form a powder coating. After the powder coating is baked at high temperature, it flows and solidifies, and the plastic particles melt into a dense final protective coating with different effects, which is firmly attached to the surface of the workpiece.

[0003] A search revealed a steel pipe powder coating device disclosed in Chinese patent application number 202321915814.9. The device includes a base with a movable groove on its upper surface. Two movable base plates are slidably connected within the movable groove and fixedly connected by a connecting plate. Two first lead screws are symmetrically arranged within the movable groove and below the movable base plates. A slider is threadedly connected to the outer side of each lead screw, and the upper surface of the slider is fixedly connected to the bottom wall of the movable base plate. The coordinated arrangement of the two movable base plates enables continuous operation of the steel pipe powder coating device, effectively improving production efficiency. The threaded connection between the lead screws and sliders allows the sliders to move the two movable base plates, enabling them to quickly move below a fan to spray multiple steel pipes positioned above the movable base plates.

[0004] Although the aforementioned patent enables continuous operation of the steel pipe powder coating device, effectively improving production efficiency, in actual use, the patent uses a lead screw to drive the slider, and the lead screw thread pair is in an open working condition, requiring frequent adjustments. In application conditions, plastic powder can easily enter the aforementioned moving pair, causing damage to the moving pair, thus reducing the service life of the lead screw to a certain extent. At the same time, the patent uses a pin to position the steel pipe, so that when the rotating column drives the support to rotate, the pin drives the steel pipe to rotate, preventing the steel pipe from rotating on its own. Consequently, when the spraying mechanism sprays the steel pipe, it can only spray the side of the steel pipe closest to the spraying mechanism, while the side of the steel pipe away from the spraying mechanism cannot be sprayed, thus reducing the powder coating effect on the steel pipe surface to a certain extent.

[0005] Therefore, a steel pipe powder coating device is needed to solve the above-mentioned problems. Utility Model Content

The main gear 11 has multiple driven gears 12 meshing on its surface. The driven gears 12 are evenly arranged in a ring around the main gear 11 and all mesh with the gear ring 10. A bearing plate 13 is provided at the bottom of the driven gears 12, and the top of the bearing plate 13 is rotatably connected to the main gear 11. A support column 14 is fixedly connected to the surface of the bearing plate 13, and a support plate 15 is fixedly connected to the bottom of the support column 14. The bottom of the support plate 15 is rotatably connected to the spray box 1. Multiple upper clamping blocks 16 are provided at the bottom of the bearing plate 13, and the multiple upper clamping blocks 16 are evenly arranged in a ring. The surface of the spray box 1 is hinged with a double door. Pressure relief ports are symmetrically opened on the top of both sides of the spray box 1, and dustproof nets are provided inside the pressure relief ports.

[0024] refer to Figure 2 and Figure 3 Multiple electric push rods 17 are fixedly connected to the bottom of the support plate 15, and the multiple electric push rods 17 correspond one-to-one with multiple upper clamping blocks 16. The output end of the electric push rod 17 passes through the support plate 15 and is rotatably connected to the lower clamping block 18, and the lower clamping block 18 cooperates with the upper clamping block 16.

[0025] As a technical optimization of this utility model, the electric push rod 17 and the lower clamping block 18 can clamp the position of the steel pipe, thereby avoiding the phenomenon that the steel pipe leaves the upper clamping block 16 due to centrifugal force during rotation, which would cause the powder coating to fail, and thus improving the stability of the steel pipe during powder coating.

[0026] refer to Figure 5 A rotating groove 19 is fixedly connected to the top of the circular groove 9. A rotating column 20 is fixedly connected to the inner wall of a plurality of gears 12, and the plurality of rotating columns 20 correspond one-to-one with a plurality of upper clamping blocks 16 and are fixedly connected to them.

[0027] As a technical optimization of this utility model, by setting the rotating groove 19 and the rotating column 20, the rotation trajectory of the driven gear 12 can be rotated, thereby improving the stability of the driven gear 12 during rotation.

[0028] refer to Figure 2 and Figure 3 The upper clamping block 16 and the lower clamping block 18 are both truncated cones, and the surfaces of the upper clamping block 16 and the lower clamping block 18 are provided with anti-slip layers.

[0029] As a technical optimization of this utility model, by setting the upper clamping block 16 and the lower clamping block 18 to be frustum-shaped, the device can use steel pipes with different inner diameters, thereby improving the practicality of the device. The anti-slip layer can also improve the friction of the surfaces of the upper clamping block 16 and the lower clamping block 18.

[0030] refer to Figure 4 The wall of the circular groove 9 is provided with a limiting groove 21, and the surface of the bearing plate 13 is fixedly connected to a limiting ring 22, and the limiting ring 22 is rotatably connected to the limiting groove 21.

[0031] As a technical optimization of this utility model, by setting the limiting groove 21 and the limiting ring 22, the bearing plate 13 can be prevented from sliding out of the circular groove 9, so that it can only rotate within the limiting groove 21.

[0032] refer to Figure 2 A stirring blade 23 is fixedly connected to the surface of the rotating shaft 7, and the stirring blade 23 is located inside the storage box 2. The top of the storage box 2 is connected to a feed pipe.

[0033] As a technical optimization of this utility model, by setting the stirring blade 23, the powder coating inside the storage box 2 can be stirred, avoiding the phenomenon of accumulation and difficulty in discharge.

[0034] The working principle and usage process of this utility model are as follows: When using this powder coating device to powder coat steel pipes, first connect the device to an external power supply, then ensure that there is a sufficient amount of powder coating powder in the storage box 2, then open the double door, and then insert the steel pipe into the top of the lower clamping block 18 so that the inner diameter of the steel pipe is engaged with the truncated cone surface of the lower clamping block 18. Then start the electric push rod 17 to move the lower clamping block 18 upward, thereby enabling the inner diameter of the top of the steel pipe to engage with the upper clamping block 16. Similarly, install other steel pipes between the lower clamping block 18 and the upper clamping block 16 in sequence and clamp them. Then close the double door, and then start the reduction motor 6 to drive the rotating shaft 7 to rotate, thereby enabling the stirring blade 23 to stir in the storage box 2 and drive the main gear 11 to rotate. Since the main gear 11 meshes with the driven gear 12, and the driven gear 12 meshes with the core of the gear ring 10, and The position of the gear ring 10 remains fixed, which drives the driven gear 12 to rotate around the main gear 11 within the gear ring 10. This, in turn, drives the rotating column 20 to rotate within the rotating groove 19, and the rotating column 20 also rotates on its own axis. At this time, multiple rotating columns 20 can drive the bearing plate 13 to rotate on its own axis, thereby enabling the support column 14 to drive the support plate 15 to rotate synchronously. The rotation of the rotating column 20 drives the upper clamping block 16 to rotate, which in turn causes the steel pipe between the lower clamping block 18 and the upper clamping block 16 to rotate on its own axis. At this time, the steel pipe rotates around the support column 14 and rotates on its own axis. Then, the solenoid valve 3 can be activated to draw the powder coating material from the storage box 2 into the distributor 4, so that the nozzle 5 can spray the steel pipe. This results in a more uniform spray coating effect on the steel pipe and prevents plastic powder from entering the transmission mechanism, thereby extending the service life of the spray coating device.
