Description

Technical Field

[0002] The sprinkler basin is one of the core components of the cooling tower. It is used to evenly distribute hot water to the filler to improve cooling efficiency. The hot water is discharged through the small holes at the bottom of the sprinkler basin. Therefore, during the processing of the sprinkler basin, it is necessary to drill holes in the sprinkler basin. Laser drilling technology is more accurate and faster, and is currently the mainstream drilling method.

[0003] The sprinkler basin is made of magnesium-aluminum-zinc-plated steel, so in the processing of the sprinkler basin, laser holes are cut on the magnesium-aluminum-zinc-plated steel plate. During the hole cutting process, nitrogen is generally sprayed at the hole cutting position to reduce oxidation of the cutting surface and make the cutting edge smoother. After the hole cutting is completed, the magnesium-aluminum-zinc-plated steel plate will be transported so that the laser cutting head can cut holes in other positions of the magnesium-aluminum-zinc-plated steel plate. However, nitrogen is still sprayed on the magnesium-aluminum-zinc-plated steel plate during the transportation process, resulting in a waste of nitrogen. Summary of the invention

The front side of the installation frame 2 is connected to the first transparent plate 41 , and the rear side of the installation frame 2 is connected to the second transparent plate 42 .

[0038] like Figure 6 and Figure 8 As shown, a guide sleeve 43 is also included. The right rear portion of the mounting plate 3 is connected to the guide sleeve 43 by bolts.

The limit plate 4 can limit the magnesium-aluminum-zinc plated steel sheet to prevent the position of the magnesium-aluminum-zinc plated steel sheet from shifting.

When a spring 17 is compressed, the first slide plate 16 moves to the left, causing the vent hole 162 to be offset from the first hard tube 9 and the second hard tube 10. During the process of conveying the magnesium-aluminum-zinc-plated steel plate, the passage between the first hard tube 9 and the second hard tube 10 is disconnected, so that nitrogen no longer enters the second hard tube 10, thereby reducing the waste of nitrogen. When the pushing portion 22 of the pushing wheel 21 is out of contact with the first slide plate 16, under the action of the first spring 17, the first slide plate 16 moves to the right, causing the vent hole 162 to correspond to the first hard tube 9 and the second hard tube 10 again, connecting the first hard tube 9 and the second hard tube 10, allowing nitrogen to enter the second hard tube 10, and automatically controlling the connection and disconnection of the first hard tube 9 and the second hard tube 10, reducing labor costs, and improving the continuity of operation.
