Hereinafter, a device for quickly handling and centering a roll of paper for an unwinder according to at least one embodiment of the present disclosure will be described with reference to the accompanying drawings.

At least one embodiment of the present disclosure provides a device for fast loading, unloading and centering a paper roll of an uncoiler, as shown in fig. 1, the device includes a motor, a controller and a paper roll, wherein clamping devices are respectively disposed at two ends of a paper core tube, the clamping devices at the two ends of the paper core tube are transversely centered or moved away from each other to realize the reeling up and reeling down of the paper roll, the clamping devices at the two ends of the paper core tube are respectively driven by a cylinder to transversely move, the controller adjusts the air pressure of the cylinder connected with the clamping devices at the two ends of the paper core tube, adjusts the positions of the left and right clamping devices, and obtains the centering of the paper roll and the central line of the.

The utility model discloses a theory of operation is:

when the uncoiler needs to replace a new coil, a rotating arm of the uncoiler rotates anticlockwise to a lower coil position, and the lower coil process is as follows: the lifting platform is adopted to ascend to a paper roll descending position, the first air cylinder 3 and the second air cylinder 18 retract from an A input position to a C output position through the first controller 13, the first sliding shaft 6 and the second sliding shaft 16 are respectively pulled to move in the first sleeve 4 and the second sleeve 17 to deviate towards two sides, and as the sliding shafts are connected with the mechanical chuck 8, the mechanical chuck 8 is driven to respectively move towards two sides and slide out from the paper core cylinder 9, so that the paper roll 10 is separated from the mechanical chuck 8 and falls on the lifting platform, and the paper roll descending work is completed;

(II) the paper roll winding process is as follows: the lifting platform rises to a new paper roll changing position, and the new paper roll 10 is coiled and manually centered through the combination of the first controller 13, the second controller 14, the first pressure regulating valve 11 and the second pressure regulating valve 12, specifically: the first controller 13 inputs the paper roll from the B input position to the D output position, and the second controller 14G inputs the paper roll from the B input position to the I output position, so that the first air cylinder 3 and the second air cylinder 18 are ejected out, the sliding shaft is pushed to move towards the middle in the first sleeve 4 and the second sleeve 17, the mechanical chuck 8 moves towards the middle due to the fact that the sliding shaft is connected with the mechanical chuck 8, the paper core barrel 9 is expanded under the action of the air cylinder force, the winding work is completed, after the paper roll 10 is changed, the motor 1 drives the belt wheel A2 and the belt wheel B5 to rotate, and the uncoiler works.

The first cylinder 3 and the second cylinder 18 may not act in the same way, which may cause the center of the new paper roll to be inconsistent with the center line of the production line, and the centering operation of the paper roll 10 is required at this time, as follows:

when the paper roll 10 is inclined to the right, the first air cylinder 3 is ejected out through the second controller 14 from an E input position to an H output position, meanwhile, the other part of the second controller 14 is input from the first controller B to a D output position and input from the second controller F to a J output position, the paper roll 10 moves to the side (left side) with small pressure due to the fact that the pressure of the second air pressure valve 12 is larger than the pressure of the first air pressure valve 11, a new paper roll is positioned by observing the positions of the first scale 7 and the second scale 15, when the paper roll 10 moves to the center position, the second controller 14 returns to the paper tightening position, the new paper roll stops at the center line position of the production line, and centering operation is completed.

(II) when the paper roll 10 deviates to the left, the second controller 14 inputs the paper roll from the F input position to the J output position, the second air cylinder 18 is ejected, the other path of the second controller 14 is input from the first controller 13B to the D output, the other path of the second controller 14 is input from the second controller E to the H output, the first air cylinder 3 is ejected, the paper roll moves to the side (right side) with small pressure due to the large pressure of the second air pressure valve 12 and the pressure of the first air pressure valve 11, a new paper roll is positioned by observing the positions of the first scale 7 and the second scale 15, when the paper roll 10 moves to the center position, the second controller 14 returns to the top paper-tight position, the new paper roll stops at the center line position of the production line, and the centering operation is completed.

The utility model discloses a scroll fast loading and unloading and centering device of decoiler has satisfied the demand that the production line speed constantly improved down, has made things convenient for the loading and unloading and the quick centering of scroll, has improved the efficiency of scroll loading and unloading and centering, has also reduced workman's working strength.
