Multiple functions can be quickly switched to improve processing efficiency.

[0047] The wall of the sliding box 3 is provided with a first inner cavity 21 and a second inner cavity 28, and the first inner cavity 21 and the second inner cavity 28 are distributed corresponding to the drying chamber 7, and the first inner cavity 21 and the second inner cavity 28 are distributed symmetrically about the axis of the cylindrical cavity 4.

The inner wall of the sliding box 3 is provided with a first air hole 22, and the first air hole 22 is provided with a plurality of first air holes 22, and the first air hole 22 is connected with the first inner cavity 21.

[0048] Before the spraying process, when the power grid metal material is located inside the drying chamber 7, gas is transported to the power grid metal material through the first inner cavity 21 and the first air hole 22 to blow away the dust on the outside of the power grid metal material. At the same time, the dust is sucked by the second air hole 29 and the second inner cavity 28 to achieve the dust removal effect; when the transported gas has a certain temperature, the power grid metal material can be preheated to improve the efficiency of the subsequent spraying process.

[0049] After the spraying process, the first inner cavity 21 and the first air hole 22 transport gas to the metal material of the power grid, and the second air hole 29 and the second inner cavity 28 suck the gas. At the same time, the gas has a certain temperature, which can dry the corrosion-resistant layer 36 and improve the processing efficiency.

[0050] A heating box 30 is fixedly connected to the outer wall of the sliding box 3. A heating device is arranged inside the heating box 30. The heating device includes an electric heater and other structures, which can quickly heat the gas passing through the heating box 30. At the same time, a filtering device can also be arranged inside the heating box 30. The filtering device includes a filter net and other structures to filter dust.

[0051] The operating table 1 is fixedly connected with a fan 31, and the heating box 30 and the fan 31 are sequentially connected between the second inner cavity 28 and the first inner cavity 21. When in use, the heating box 30 and the fan 31 cooperate to realize gas circulation, and the gas is transported from the first inner cavity 21 and the first air hole 22 to the metal material of the power grid, and the gas is sucked by the second air hole 29 and the second inner cavity 28.

[0052] In order to adjust the position of the partition 6, an electric push rod 20 is fixedly connected to the outer wall of the slide box 3, and the partition 6 is fixedly connected to the telescopic end of the electric push rod 20. A long slot 32 is provided on the operating table 1 for the electric push rod 20 to pass through. When the slide box 3 moves downward, the partition 6 is attached to the top of the operating table 1, and the electric push rod 20 is retracted into the inside of the long slot 32.

[0053] In order to achieve the support and positioning of the metal material of the power grid, a disk box 9 for driving the metal part to rotate is arranged at the bottom end of the cylindrical cavity 4, and a support block 10 is fixedly connected to the top of the disk box 9. When in use, a clamping assembly is arranged on the support block 10. The clamping assembly includes structures such as a splint, which can fix and position the metal material of the power grid to facilitate subsequent operations.

[0054] An annular groove 11 is provided on the outer ring of the disk box 9 , and an airbag ring 12 is fixedly connected inside the annular groove 11 . An air groove 13 is provided on the inner wall of the disk box 9 , and the disk box 9 is connected to the airbag ring 12 through the air groove 13 .

[0055] A vertical plate 15 is fixedly connected to the lower surface of the operating table 1, and a bottom box 16 is fixedly connected to the bottom end of the vertical plate 15. The bottom box 16 and the vertical plate 15 are distributed in an L shape. The end of the bottom box 16 away from the vertical plate 15 is rotatably connected to a vertical pipe 14, and the top of the vertical pipe 14 is fixedly connected to the disk box 9, and the vertical pipe 14 is connected to the disk box 9. A motor 18 is fixedly connected to the lower surface of the bottom box 16, and the vertical pipe 14 is fixedly connected to the driving shaft of the motor 18. A square groove 17 is opened on the outer wall of the vertical pipe 14, and the vertical pipe 14 is connected to the bottom box 16 through the square groove 17.

[0056] The bottom box 16 cooperates with the fan 31 , and a pressure relief component is provided on the bottom box 16 , including a pressure relief valve and other structures.

[0057] Specifically, the telescopic end of the electric push rod 20 is controlled to extend, driving the partition 6 to slide outward, and the drying chamber 7 and the coating chamber 8 are connected. The gas inside the airbag ring 12 is discharged through the pressure relief component, so that the airbag ring 12 shrinks and is recovered to the inside of the annular groove 11. At this time, the airbag ring 12 does not abut against the inner wall of the drying chamber 7, and does not affect the passing of the coating device 19. The slide box 3 is controlled to move downward, and the electric push rod 20 enters the inside of the long groove 32. The operator loads the material, fixes the metal material of the power grid on the support block 10, and then covers the top of the slide box 3 with a sealing cover, and the fan 31, the bottom box 16, the vertical pipe 14, the disc box 9 and the air groove 13 transport gas to the inside of the airbag ring 12, so that the air groove 13 and the airbag ring 12 expand and abut against the inner wall of the drying chamber 7, and the abutment force of the airbag ring 12 is appropriate, which does not affect the rotation of the disc box 9.

[0058] Furthermore, gas is transported to the metal material of the power grid through the first inner cavity 21 and the first air hole 22 to blow away dust on the outside of the metal material of the power grid. At the same time, the dust is sucked by the second air hole 29 and the second inner cavity 28 to achieve the dust removal effect. At the same time, the gas has a certain temperature and can preheat the metal material of the power grid.

[0059] Furthermore, the motor 18 drives the metal material of the power grid to rotate through the vertical pipe 14 and the disk box 9, thereby achieving uniform processing of the metal material of the power grid.

[0060] After the treatment is completed, the gas inside the airbag ring 12 is discharged through the pressure relief component, so that the airbag ring 12 shrinks and recovers to the inside of the annular groove 11. At this time, the airbag ring 12 does not abut against the inner wall of the drying chamber 7, and does not affect the passage of the coating equipment 19. The slide box 3 is controlled to move upward and reset, and then the telescopic end of the electric push rod 20 is controlled to be recovered, driving the partition 6 to be recovered, and the drying chamber 7 and the coating chamber 8 are separated. At this time, the metal material of the power grid is inside the coating chamber 8, and the coating equipment 19 sprays the metal material of the power grid.

[0061] After the spraying treatment, the slide box 3 is controlled to move downward again according to the above steps, so that the metal material of the power grid after the spraying treatment enters the interior of the drying chamber 7 for drying treatment.

[0062] By setting up structures such as the disc box 9 and the airbag ring 12, the metal material of the power grid is driven to rotate to achieve uniform treatment of the metal material of the power grid. At the same time, when the airbag ring 12 expands, it can ensure that the metal material of the power grid can be sprayed and other treatments in a closed space. When the airbag ring 12 contracts, it does not affect the switching of the metal material of the power grid between the drying chamber 7 and the coating chamber 8.

[0063] In order to improve the use efficiency, a round rod 24 is passed through the inside of the first air hole 22, and the inner diameter of the round rod 24 is smaller than the inner diameter of the first air hole 22, and a round hole for the round rod 24 to pass through is opened on the side wall of the slide box 3, and one end of the round rod 24 located inside the cylindrical cavity 4 is fixedly connected with a guide block 25, and a square block 23 is arranged outside the slide box 3, and the round rod 24 is fixedly connected to the square block 23, and the lower surface of the square block 23 is fixedly inlaid with a first magnet 26, and a second magnet 27 is arranged inside the partition 6, and the first magnet 26 and the second magnet 27 are attracted and matched.

[0064] Specifically, during dust removal, drying, etc., the partition 6 slides outward. When the first magnet 26 and the second magnet 27 are relatively distributed, the partition 6 and the block 23 can be moved synchronously under the action of the attraction between the first magnet 26 and the second magnet 27, and the telescopic end of the electric push rod 20 is controlled to reciprocate and retract, thereby driving the guide block 25 to move through the block 23 and the round rod 24, stirring the gas blown out of the first air hole 22, expanding the scope of wind force, and avoiding direct blowing on the corrosion-resistant material outside the metal material. In this process, the moving distance of the partition 6 is limited, so that the block 23 can move back and forth.
