Description

Technical Field

[0001] This utility model relates to the field of cold rolling mill technology, and in particular to an online cleaning device for aluminum chips on guide rollers of aluminum alloy strip in cold rolling mills. Background Technology

[0002] The online aluminum shavings cleaning device for aluminum alloy strip guide rollers in cold rolling mills is a specialized device for removing aluminum shavings from the guide rollers during the production process of cold rolling mills. It utilizes adsorption, mechanical cleaning, and high-pressure blowing principles to remove the aluminum shavings.

[0052] Given the current technology, after the blowing pipe blows the aluminum chips off the guide roller, the aluminum chips will scatter, some falling to the ground and some being blown onto the aluminum alloy strip above the guide roller, causing damage to the aluminum alloy strip and even causing them to re-attach to the aluminum alloy strip.

[0053] Please see Figure 1-5 As shown, this embodiment is an online aluminum chip cleaning device for aluminum alloy strip guide rolls in a cold rolling mill, comprising:

[0054] Guiding and cleaning device 1, the guiding and cleaning device 1 includes:

[0055] Support frame 12;

[0056] Guide roller 13 is rotatably connected to the inside of support frame 12;

[0057] The connecting pipe 15 is fixed to the side of the support frame 12, and the blowpipes are evenly distributed on it;

[0058] The guiding and cleaning device 1 also includes:

[0059] The support column 11 is fixed to the ground, and the side of the support frame 12 is fixed to the support column 11;

[0060] The support plate 14 is fixed to the other side of the support frame 12, and the connecting pipe 15 is fixed to the support plate 14;

[0061] The guiding and cleaning device 1 also includes:

[0062] One end of the hose 16 is fixed to the end of the connecting pipe 15 near the through hole 23, and the other end is connected to the external air compressor;

[0063] The guiding and cleaning device 1 is used to support the aluminum alloy strip, guide it, and clean aluminum chips on the guide roller 13. The support column 11 provides support, the support frame 12 provides support, and facilitates the rotation of the guide roller 13. The support plate 14 provides support and is used to fix it to the connecting pipe 15. The connecting pipe 15 provides an airflow channel and has evenly arranged blowpipes that blow air onto the guide roller 13. The hose 16 is used to connect to an external air compressor.

[0064] Splash protection component 2, which includes:

[0065] The first L-shaped protective cover 21 is fixed to the side of the support frame 12 and wraps around the outside of the connecting pipe 15;

[0066] Sealing plate 22 is fixed on both sides of the first L-shaped protective cover 21;

[0067] A through hole 23 is formed on one of the sealing plates 22, and one end of the connecting pipe 15 is inserted into the through hole 23;

[0068] The first rubber strip 26 is fixed at one end to one side of the top of the first L-shaped protective cover 21;

[0069] The second L-shaped protective cover 27 is fixed on the other side of the support frame 12;

[0071] Splash protection component 2 also includes:

[0072] The sealing ring 24 is fixed in the through hole 23 and wrapped around the outside of the connecting pipe 15;

[0073] The rubber pad 25 is fixed to the top of the first L-shaped protective cover 21, and the upper end is an arc-shaped protrusion;

[0074] The other ends of the first rubber strip 26 and the second rubber strip 28 are attached to the guide roller 13;

[0075] The anti-splash assembly 2 prevents aluminum chips from flying everywhere. The first L-shaped protective cover 21 and the second L-shaped protective cover 27 act as a barrier, the sealing plate 22 acts as a seal, the through hole 23 allows the connecting pipe 15 to extend, the sealing ring 24 acts as a seal, the rubber pad 25 prevents the aluminum alloy strip from hitting the first L-shaped protective cover 21 and causing damage, and the first rubber strip 26 and the second rubber strip 28 are used to adhere to the guide roller 13 to further prevent aluminum chips from flying out.

[0076] Working principle:

[0077] The first L-shaped protective cover 21 and the second L-shaped protective cover 27 are fixed on both sides of the guide roller 13, the sealing ring 24 is sleeved on the connecting pipe 15 and inserted into the through hole 23, the connecting pipe 15 is fixed on the support plate 14, and finally the first rubber strip 26 and the second rubber strip 28 are fixed on the top of the first L-shaped protective cover 21 and the second L-shaped protective cover 27, respectively, so that the first L-shaped protective cover 21 and the second L-shaped protective cover 27 are in contact with the guide roller 13. The high-pressure air in the connecting pipe 15 is blown to the guide roller 13 through the blowpipe. The aluminum chips are blocked by the first L-shaped protective cover 21, the second L-shaped protective cover 27, the first rubber strip 26 and the second rubber strip 28 and fall to the ground, and will not be blown onto the aluminum alloy strip.

[0078] This step prevents aluminum shavings from flying and scratching the aluminum alloy strip.

[0079] Please see Figure 4-6 This embodiment, based on the above embodiments, further includes:

[0080] Leak-proof component 3, which includes:

[0081] Connecting strips 34 are respectively fixed to the top of the first L-shaped protective cover 21 and the second L-shaped protective cover 27;

[0082] The arc-shaped support bar 33 is fixed between the two connecting bars 34, and the arc-shaped support bar 33 is located on both sides of the guide roller 13;

[0083] The third rubber strip 35 is fixed on the connecting strip 34 and the arc-shaped support strip 33, and the guide roller 13 and the support frame 12 are respectively attached to both sides;

[0084] Leak-proof component 3 also includes:

[0085] The first groove 31 is formed at one end of the first rubber strip 26;

[0086] The second groove 32 is formed at one end of the second rubber strip 28;

[0087] Leak-proof component 3 also includes:

[0088] The opening 36 is made on the inner bottom plate of the support frame 12 and is evenly distributed;

[0089] The leak-proof component 3 prevents aluminum chips from flying out from both sides of the guide roller 13. The first slot 31 and the second slot 32 facilitate the fixing of the connecting strip 34 to the first L-shaped protective cover 21 and the second L-shaped protective cover 27. The arc-shaped support strip 33 provides support, the third rubber strip 35 provides a sealing function, and the opening 36 facilitates the falling of aluminum chips that fall into the support frame 12.

[0090] Working principle:

[0091] The connecting strips 34 at both ends of the arc-shaped support strip 33 are inserted into the first slot 31 and the second slot 32 and fixed with screws. Then, the third rubber strip 35 is attached to the arc-shaped support strip 33 and the connecting strip 34 and fixed with screws. When in use, the blowpipe on the connecting pipe 15 will cause aluminum shavings on the guide roller 13 to fall off. Part of them are blocked by the first L-shaped protective cover 21, the second L-shaped protective cover 27, the first rubber strip 26 and the second rubber strip 28 and fall to the ground. The other part is blocked by the third rubber strip 35 and falls to the ground. The aluminum shavings that fall on the inner bottom surface of the support frame 12 will fall out from the opening 36.

[0092] This step prevents aluminum chips from flying out from the gaps on both sides of the guide roller 13 and the support frame 12, further avoiding damage to the aluminum alloy strip.

[0093] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
