[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a hood-type dust removal device for the processing area of ​​a silicon steel uncoiler, comprising:

[0029] The base 1 has a ring track 2 on its top and multiple casters 3 on its bottom.

[0030] Arc-shaped block 4 is slidably connected within the annular track 2, and a negative pressure buffer chamber 5 is provided inside the arc-shaped block 4;

[0031] Two arc-shaped plates 6 are connected to the arc-shaped block 4, and a steel strip gap 7 is formed between the two arc-shaped plates 6. An air pressure chamber 8 is provided inside the arc-shaped plate 6, and the air pressure chamber 8 is connected to the negative pressure buffer chamber 5. Multiple air holes 9 are opened on the inner wall of the arc-shaped plate 6, and the multiple air holes 9 are connected to the air pressure chamber 8.

[0032] A vacuum cleaner 10 is mounted on the base 1 and is connected to the negative pressure buffer chamber 5 via a hose 11.

[0033] The annular track 2 is provided with a waist-shaped groove 12. The stop bolt 13 passes through the waist-shaped groove 12 and is screwed onto the arc-shaped block 4. The stop bolt 13 abuts against the annular track 2. Tightening the stop bolt 13 can lock the position of the arc-shaped block 4 on the annular track 2, thereby facilitating the adjustment of the position of the arc-shaped plate 6.

[0034] The flexible tube 11 passes through the waist-shaped groove 12;

[0035] The annular track 2 is provided with an annular slide 14 with a T-shaped cross section. The arc block 4 is slidably connected in the annular slide 14 and abuts against the inner wall of the annular slide 14. The arc plate 6 extends into the annular slide 14 and both the inner and outer walls of the arc plate 6 abut against the inner wall of the annular track 2, ensuring that the arc block 4 and the arc plate 6 slide stably along the annular track 2.

[0036] The waist-shaped groove 12 is arc-shaped, and the axis of the waist-shaped groove 12 coincides with the axis of the annular track 2.

[0037] Working principle: First, after the uncoiler finishes winding, the base 1 is pushed to one side of the uncoiler under the rolling support of the casters 3. The casters 3 are adjusted to support and fix the base 1, so that the steel strip passes through the steel strip gap 7, the arc plate 6 is close to the surface of the steel coil, and multiple air holes 9 are aligned with the steel coil. Second, the negative pressure generated by the vacuum cleaner 10 enters the air pressure chamber 8 through the negative pressure buffer chamber 5 and is released at the air holes 9. During the unwinding process, the dust falling off the surface of the steel strip enters the vacuum cleaner 10 through the air holes 9, preventing the magnesium oxide on the surface of the steel strip from being blown into the unwinding operation environment. Finally, when the position of the arc plate 6 needs to be adjusted, the stop bolt 13 is loosened, and the arc plate 6 and the arc block 4 are pushed to slide together along the annular slide 14. At this time, the stop bolt 13 slides along the waist groove 12. After the adjustment is completed, the stop bolt 13 is tightened, and the stop bolt 13 abuts against the annular track 2 to lock the position of the arc block 4 on the annular track 2.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
