[0027] like Figure 1-4As shown, the utility model provides a technical solution: a dust-proof dust collecting cover for sheet metal processing with a protective function, comprising a cover body 1, a plurality of protective belts 4 are provided at the bottom end of the cover body 1, two ventilation pipes 5 are fixedly connected to the top of the cover body 1, an adjustment device 2 is provided on the outer surface of the cover body 1, and the adjustment device 2 includes two slot rods 21 and a rectangular frame 24, the two slot rods 21 are fixedly connected to the two sides of the top of the cover body 1, a motor 22 is provided on one side of the top of the slot rod 21, a screw 23 is fixedly connected to the output end of the motor 22, and the screw 23 is fixedly connected to the output end of the motor 22. Located inside a slot rod 21, sliders 25 are fixedly connected on both sides of the inner wall of the rectangular frame 24. The outer surface of the slider 25 slides on the inner wall of the slot rod 21. The outer surface of the screw 23 is threadedly connected to the inner wall of a slider 25. The inner wall of the rectangular frame 24 is slidably connected to a sliding frame 26. The bottom end of the sliding frame 26 is provided with a plurality of springs 27. The upper and lower ends of the spring 27 are respectively fixedly connected to the bottom end of the sliding frame 26 and the bottom end of the inner wall of the rectangular frame 24. The top of the slot rod 21 is fixedly connected to two pressure rods 29. By setting the adjustment device 2, the set When the protective strip 4 is used as a dustproof material for the cover, the sliding frame 26 and the rectangular frame 24 will be located at the top of the cover body 1. The top of the sliding frame 26 will contact the two pressure rods 29 on the outer surface of the slot rod 21 and compress the spring 27 at the bottom end of the sliding frame 26. When the rectangular frame 24 needs to be used as a dustproof material, the motor 22 can be operated to drive the screw 23 to rotate, so that the two sliders 25 on the inner wall of the rectangular frame 24 slide downward on the inner wall of the slot rod 21 to lower the rectangular frame 24 to adjust the height position. At the same time, the rectangular frame 24 will slide on the outer surface of the sliding frame 26. The compressed spring 27 restores the original shape and pushes the sliding frame 26 to keep the sliding frame 26 in place, and the rectangular frame 24 and the sliding frame 26 are unfolded. The rectangular frame 24 and the sliding frame 26 are used to prevent dust from surrounding the processing equipment. The motor 22 drives the screw 23 to rotate and adjust the height position of the rectangular frame 24 and the sliding frame 26 and unfold the sliding frame 26 and the rectangular frame 24, so that the user can choose to use the protective belt 4 or the rectangular frame 24 as a dust-proof material according to needs when using the dust cover, thereby improving the practicality and flexibility of using the dust cover.

[0028] Specifically, such as Figure 2-4 As shown, positioning rods 28 are fixedly connected to the four corners of the top of the cover body 1, and the four corners of the inner wall of the rectangular frame 24 slide on one side of the positioning rods 28. When the rectangular frame 24 moves up and down, the four corners of the inner wall will slide on one side of the positioning rods 28. The positioning rods 28 can further limit the angle between the rectangular frame 24 and the cover body 1, thereby avoiding the angle of the rectangular frame 24 from being deflected as much as possible.

[0029] Specifically, such as Figure 2-4As shown, a plurality of round rods 210 are fixedly connected to the bottom end of the inner wall of the rectangular frame 24, and the sliding frame 26 slides on the outer surface of the round rod 210. The round rod 210 is located inside the spring 27. When the sliding frame 26 moves up and down on the inner wall of the rectangular frame 24 and the spring 27 is deformed, the spring 27 will move on the outside of the round rod 210. The round rod 210 can be used to reinforce the internal shape of the spring 27 to avoid the spring 27 from twisting as much as possible. Support rods 211 are fixedly connected to the four corners of the top of the cover body 1. The end of the support rod 211 away from the cover body 1 is fixedly connected to one side of the positioning rod 28. By setting the support rod 211, the end of the positioning rod 28 away from the cover body 1 can be supported. The inner wall of the rectangular frame 24 is supported by the support rod 211 and the positioning rod 28, thereby improving the structural stability of the integrated cover.

[0030] Specifically, such as Figure 1 、 Figure 3 and Figure 5 As shown, a protective device 3 is provided on the outer surface of the rectangular frame 24, and the protective device 3 includes a rubber frame 33. Elastic metal rods 32 are fixedly connected to both sides of the inner wall of the rubber frame 33. Two slots 31 are respectively provided in the rectangular frame 24. When using the dust cover, the elastic metal rods 32 on both sides of the inner wall of the rubber frame 33 can be bent outward to cause slight deformation, and then the two ends of the two elastic metal rods 32 are respectively inserted into the two slots 31 on both sides of the outer surface of the rectangular frame 24, and the rubber frame 33 is installed on the outer surface of the rectangular frame 24 to protect the outer surface of the rectangular frame 24 to avoid the rectangular frame 24 from being damaged by impact as much as possible, thereby improving the durability of the rectangular frame 24.

[0031] Specifically, such as Figure 3 and Figure 5 As shown, the two ends of the elastic metal rod 32 are fixedly connected with a plurality of anti-slip protrusions 35, and the anti-slip protrusions 35 are linearly distributed at the two ends of the outer surface of the elastic metal rod 32. By providing the anti-slip protrusions 35, the friction force when the two ends of the elastic metal rod 32 are inserted into the slot 31 and contact the inner wall of the slot 31 can be increased, so that the two ends of the elastic metal rod 32 are not easily accidentally slipped out from the inside of the slot 31.

[0032] The working principle of this utility model is:

[0033] S1. When installing the dust hood, you can first bend the elastic metal rods 32 on both sides of the inner wall of the rubber frame 33 outward to slightly deform them, and then insert the two ends of the two elastic metal rods 32 into the two slots 31 on both sides of the outer surface of the rectangular frame 24, and install the rubber frame 33 on the outer surface of the rectangular frame 24 to protect the outer surface of the rectangular frame 24 as much as possible to prevent the rectangular frame 24 from being damaged by impact. Then, connect the top of the hood body 1 to the dust collection equipment inside the workshop, and install the hood body 1 on the top of the processing equipment.

[0034] S2. When the processing equipment is working, the protective belt 4 is used as a dustproof material, and the protective belt 4 and the cover body 1 are used to prevent debris and dust from splashing outside the processing environment as much as possible. The sliding frame 26 and the rectangular frame 24 will be located at the top of the cover body 1. The top of the sliding frame 26 will contact the two pressure rods 29 on the outer surface of the slot rod 21 and compress the spring 27 at the bottom of the sliding frame 26. When the rectangular frame 24 needs to be used as a dustproof material, the motor 22 can be operated to drive the screw 23 to rotate, so that the two sliders 25 on the inner wall of the rectangular frame 24 move toward the inner wall of the slot rod 21. The downward sliding makes the rectangular frame 24 drop to adjust the height position. At the same time, the rectangular frame 24 will slide on the outer surface of the sliding frame 26, and the compressed spring 27 will restore the original state to push the sliding frame 26 to keep the sliding frame 26 in place. The rectangular frame 24 and the sliding frame 26 will be unfolded, and the rectangular frame 24 and the sliding frame 26 will be used to prevent dust from surrounding the processing equipment.
