Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a roller surface cleaning device of a six-roller rolling mill used in copper foil production. Background Art

[0002] Rolling mills need to add rolling oil during the production process, but after rolling is completed, the rolling oil on the working rolls will absorb the metal dust generated in the production process, resulting in the rough surface of the copper foil produced subsequently and shortening the service life of the working rolls. In the prior art, there are two main ways to clean the rolls: online cleaning and disassembly cleaning. Online cleaning mostly involves adding cleaning devices such as rubber scrapers or oil squeeze rollers to the rolling mill. For an X-type six-roll press, there are support rolls with larger diameters on both sides of its working rolls, and there is insufficient space on both sides of the working rolls to add additional devices for online cleaning. When the disassembly cleaning method is selected to complete the cleaning work, dust will also adhere to the grinding roll of the disassembly cleaning device when cleaning the rolls. During the continuous grinding process, the dust on the grinding roll may adhere to the roll again, resulting in incomplete cleaning, and even the dust on the grinding roll may cause additional scratches on the roll.

A bearing seat 18 is provided at the upper part of the support column 16 at the same height as the extrusion roller 4.

[0033] A fine roller 9 is provided between the brush roller 6 and the right driven roller 3. The fine roller 9 is located inside the rubber belt 5 and can move up and down between the two support plates 1. When the fine roller 9 is at the upper dead point of the moving stroke, the lower end of the fine roller 9 is higher than the lower end of the active roller 2, and when the fine roller 9 is at the lower dead point of the moving stroke, the lower end of the fine roller 9 is lower than the lower end of the active roller 2; it is ensured that the fine roller 9 can stretch the rubber belt 5 between the two active rollers 2 when it is at the lower end. A through groove 10 is provided on both support plates 1. The two through grooves 10 are aligned front and back, and a round hole is provided at the bottom of the through groove 10.

The nuts 12 are provided with two, which are convenient for locking during use to prevent the nuts 12 from loosening during operation and causing the screw rod 11 to move upward.

[0034] The outer surface of the active roller 2 is made of rubber material, which increases the friction between the two active rollers 2 and the rubber belt 5 and ensures the transmission effect. The outer surface of the driven roller 3 on the left is made of metal material to reduce the flow resistance of the rolling oil on the driven roller 3.

[0035] An oil collecting tank 13 is fixed between the two support plates 1. The oil collecting tank 13 is located below the left driven roller 3 and the brush roller 6, and an oil outlet is opened at the bottom of the oil collecting tank 13 to accommodate the rolling oil dripping from the left driven roller 3 and the powder brushed off by the brush roller 6.

[0036] Working principle:

[0037] When the utility model is in use, the disassembled working roll of the rolling mill is fixed on the two supporting columns 16 through the bearing seat 18, and then the two supporting columns 16 are slid synchronously until a suitable extrusion force is generated between the working roll and the rubber belt 5 outside the squeezing roll 4, and all the screws at the lower ends of the two supporting columns 16 are tightened to ensure that the supporting columns 16 are fixed; then the gear 8 and the working roll are connected to the external power respectively; at this time, the fine roll 9 is located above the through groove 10, the rubber belt 5 between the two active rolls 2 is not stretched, and the entire rubber belt 5 is in a taut state to avoid the rubber belt 5 being in a stretched state for a long time and being damaged;

[0038] When cleaning the working rollers, first turn the nuts 12 on both sides, pull the fine roller 9 to the bottom through the two screws 11, and the rubber belt 5 between the two active rollers 2 is stretched; then start the external power to drive the gear 8 and the working roller to rotate counterclockwise, and the gear 8 drives the active roller 2 and the brush roller 6 on the left to rotate counterclockwise through the active roller 2 and the belt on the right, and the two active rollers 2 then drive the rubber belt 5 to rotate counterclockwise, and the belt drives the two driven rollers 3 to rotate clockwise. Since the two active rollers 2 are connected by a belt, the rotation speeds of the two active rollers 2 are the same, that is, the length of the rubber belt 5 stretched between the two active rollers 2 remains unchanged, and the rubber belt 5 will not become tighter and tighter;

[0039] Since both the working roller and the rubber belt 5 rotate counterclockwise, a wiping action will occur at the position where the rubber belt 5 is squeezed with the working roller, and the rolling oil and powder attached to the working roller are transferred to the rubber belt 5 and rotate with the rubber belt 5 to the position of the active roller 2 on the left. Since the driven roller 3 presses the rubber belt 5 against the lower edge of the active roller 2 from below, the rolling oil attached to the rubber belt 5 will be squeezed and concentrated between the driven roller 3 and the rubber belt 5 on the left, and finally flow downward along the outer surface of the driven roller 3 on the left and drip into the oil collecting tank 13, and then discharged through the oil outlet. Since the driven roller 3 rotates in the clockwise direction, the rolling oil flowing downward along the driven roller 3 will never appear on the right side of the left driven roller 3, and will not cause secondary pollution to the rubber belt 5 on the right side of the left driven roller 3. At the same time, the degreasing method for the rubber belt 5 here is squeezing, and there is no relative rotation between the rubber belt 5 and the active roller 2 or the driven roller 3, so the rubber belt 5 will not be worn here.

[0040] After the rubber belt 5 passes through the active roller 2 and the driven roller 3 on the left, powder may still be attached to the rubber belt 5. However, since the rolling oil has been removed, the adhesion of the powder to the rubber belt 5 has been reduced. At the same time, the rubber belt 5 between the two active rollers 2 is stretched under the action of the fine roller 9, resulting in the misalignment of the adhesion surface between the powder and the rubber belt 5, further reducing the adhesion of the powder to the rubber belt 5. The rubber belt 5 is then cleaned by the brush roller 6 on the outside of the rubber belt 5 to complete the powder removal work on the rubber belt 5, so that when the rubber belt 5 reaches the extrusion position with the working roller again, the rubber belt 5 is clean and pollution-free.

[0041] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Technical personnel familiar with the technical field can make equivalent replacements or changes according to the technical scheme and utility model concept of the utility model within the technical scope disclosed by the utility model, and all of them should be included in the protection scope of the utility model.
