When the sheet metal roll body 12 is released for processing, the sheet metal roll body 12 moves and drives the first roller 16 to rotate at the same time. When the thickness of the sheet metal roll body 12 continues to decrease, the first telescopic spring rod 14 will be continuously stretched to make the first roller 16 close to the surface of the sheet metal roll body 12. In this step, the first telescopic spring rod 14 is arranged to connect the first roller 16 to support and clamp the sheet metal roll body 12 from the surface of the sheet metal roll body 12, thereby reducing the sheet metal roll body 12 from bouncing up and moving faster due to the inertia force when it is released, resulting in the looseness of the sheet metal roll body 12, which can improve the stability of the sheet metal roll body 12 when it is released.

In this step, by setting the fixing hole 22 to connect the connecting rod 21 and the second roller 24, the sheet metal roll body 12 with a shorter width can be fixed from the surface, and the sheet metal roll body 12 with different widths can be adapted to improve the applicability of fixing.

[0026] Reference Figures 1 to 4As shown, a pair of electric push rods 3 are fixedly connected to the side walls of the first fixed plate 11; a push plate 31 is fixedly connected to the end of the electric push rod 3; during operation, when the sheet metal roll body 12 is about to stop being released, starting the electric push rod 3 can drive the push plate 31 to move toward the side of the sheet metal roll body 12, and when the push plate 31 contacts the side of the sheet metal roll body 12, the two sides of the sheet metal roll body 12 can be supported. In this step, the electric push rod 3 is set to drive the push plate 31 to contact the two sides of the sheet metal roll body 12, so that the sheet metal roll body 12 can be supported and fixed from both sides, thereby reducing the loosening of the sheet metal roll body 12 due to the inertial force when the sheet metal roll body 12 is released.

When the thickness of the sheet metal roll body 12 continues to decrease, the third telescopic spring rod 5 stretches to drive the brush roller 51 and the bristles 52 to be in close contact with the surface of the sheet metal roll body 12. In this step, by setting the third telescopic spring rod 5 to connect the brush roller 51 and the bristles 52, the surface of the sheet metal roll body 12 can be cleaned when the sheet metal roll body 12 is continuously moving, so as to reduce impurities such as dust or metal debris adhering to the surface of the sheet metal roll body 12, and improve the cleanliness of the surface of the sheet metal roll body 12.

[0029] Reference Figure 2As shown, a collecting groove 6 is fixedly connected to the top of the bottom plate 1; the collecting groove 6 is arranged below the brush roller 51; during operation, after the bristles 52 clean the dust or metal debris and other impurities on the surface of the sheet metal roll body 12, some of the impurities will fall into the collecting groove 6 below, and the collecting groove 6 will collect the fallen impurities. In this step, the dust or metal debris and other impurities cleaned by the bristles 52 can be collected by setting the collecting groove 6, so as to reduce the situation where impurities are scattered on the surface of the bottom plate 1 and cause dirt and accumulation.

[0030] Reference Figure 2 As shown, a draw box 7 is placed in the collecting groove 6; the draw box 7 and the collecting groove 6 are slidably matched; during operation, when impurities enter the collecting groove 6, the draw box 7 is located in the collecting groove 6 and the impurities can be collected in the draw box 7. When the collection is completed, the draw box 7 is drawn out of the collecting groove 6, and then the impurities in the draw box 7 are poured out and the draw box 7 is reset.

[0032] During operation, after the sheet metal roll body 12 is placed in the middle of the first fixed plate 11, the first roller 16 will contact the surface of the sheet metal roll body 12 and can support the sheet metal roll body 12 from the surface. When the sheet metal roll body 12 is released for processing, the sheet metal roll body 12 will drive the first roller 16 to rotate at the same time when the sheet metal roll body 12 moves. When the thickness of the sheet metal roll body 12 continues to decrease, the first telescopic spring rod 14 will continue to stretch so that the first roller 16 is close to the surface of the sheet metal roll body 12. When the width of the sheet metal roll body 12 is short, the second roller 24 can be driven to move toward the sheet metal roll body 12 by pulling the connecting rod 21.

The wheel 42 will contact the side of the sheet metal roll body 12. When the push plate 31 continues to move toward the side of the sheet metal roll body 12, the second spring telescopic rod 41 will shrink, driving the third roller 42 to move toward the rubber pad 43. When in contact with the rubber pad 43, the friction force generated between the rubber pad 43 and the third roller 42 can slow down the rotation of the third roller 42. When the sheet metal roll body 12 is released and moved, it will drive the brush roller 51 and the bristles 52 to rotate at the same time. At this time, the surface of the sheet metal roll body 12 can be cleaned. When the thickness of the sheet metal roll body 12 continues to decrease, the third telescopic spring rod 5 stretches and drives the brush roller 51 and the bristles 52. It is in close contact with the surface of the sheet metal roll body 12. After the bristles 52 clean the dust, metal debris and other impurities on the surface of the sheet metal roll body 12, some of the impurities will fall into the collecting groove 6 below. At this time, the collecting groove 6 will collect the fallen impurities. When the impurities enter the collecting groove 6, the drawer box 7 is located in the collecting groove 6 and can collect the impurities in the drawer box 7. When the collection is completed, the drawer box 7 is pulled out of the collecting groove 6, and then the impurities in the drawer box 7 are poured out and the drawer box 7 is reset. When the third roller 42 moves to contact with the rubber pad 43, the rubber block 8 will contact the side of the sheet metal roll body 12 and can be supported and fixed from its side.
