As shown in fig. 1 and 2, the present application provides a paper roll centering device, which comprises a base 1, a paper support frame base 2, a paper support frame 3 and at least 2 centering executing pieces 4. The paper support frame base 2 is arranged on the base 1, the paper support frame 3 is connected to the paper support frame base 2 in a sliding mode, the executing parts 4 in each pair are arranged on two sides of the paper support frame 3 along the sliding direction of the paper support frame 3 respectively, and the executing parts 4 in each pair can be close to or far away from each other along the sliding direction of the paper support frame 3.
Wherein, hold in the palm paper frame 3 and be used for bearing the weight of the scroll, the scroll rolls to holding in the palm on the paper frame 3 from feed end or last station. The centering executing parts 4 are respectively arranged at two sides of the paper support frame 3 along the sliding direction of the paper support frame 3, namely, the centering executing parts 4 are distributed at two ends of the paper roll. When the centering executing pieces 4 approach each other along the sliding direction of the paper support 3, the paper roll is clamped and is driven to move to the centering position. When the centering actuators 4 are moved away from each other in the sliding direction of the paper holder 3, the paper roll is released, facilitating the transfer of the paper roll to the packaging station or the next station. When the centering executive component 4 centers the paper roll, the paper support frame 3 can be connected to the paper support frame base 2 in a sliding manner, and the friction force between the paper support frame 3 and the paper roll is far greater than the friction force between the paper support frame 3 and the paper support frame base 2, so that the paper support frame 3 and the paper roll cannot move relatively. The paper roll is driven to move to the centering position by the movement of the paper supporting frame 3 relative to the paper supporting frame base 2.
Compare in current scroll centering device, the scroll centering device of this application can not make and hold in the palm and produce wearing and tearing between paper frame 3 and the scroll, has effectively protected the safety of scroll, also consequently can promote the centering speed of scroll, improves centering efficiency.
As shown in fig. 8, in one embodiment, the centering actuator 4 includes a frame-type stopper, a timing belt, a reduction motor, and the like. The frame-shaped stop frame is connected to the synchronous belt through the clamp, and the speed reducing motor drives the synchronous belt to rotate, so that the frame-shaped stop frame is driven to move. Specifically, the frame-shaped stopping frame on one side is connected to the upper edge of the synchronous belt, and the frame-shaped stopping frame on the other side is connected to the lower edge of the synchronous belt. When the synchronous belt rotates forwards, the frame-shaped stopping frames on the two sides approach to each other synchronously; when the synchronous belt rotates reversely, the frame-shaped stopping frames on the two sides are away from each other synchronously.
As shown in fig. 3 to 6, in one embodiment, the paper holder base 2 is provided with a slide rail 8 arranged along the sliding direction of the paper holder 3, and the paper holder 3 is slidably connected to the slide rail 8.
The paper support frame 3 slides on the paper support frame base 2 through the slide rail 8, so that the resistance of the paper support frame 3 moving on the paper support frame base 2 is reduced conveniently. When the centering executive component 4 drives the paper roll to move towards the middle sole, the paper roll and the paper support frame 3 do not move relatively, and the paper roll moves to the centering position through relative sliding of the paper support frame 3 and the paper support frame base 2.

Specifically, the first abutting portion 51 extends and bends upward, and the second abutting portion 41 is provided downward. The first resisting portion 51 and the second resisting portion 41 can form a hooking state, so that the second resisting portion 41 drives the first resisting portion 51 to move.
In one embodiment, the cradle base 2 is rotatably mounted to the base 1, as shown in fig. 5 and 6.
After the centering action of the paper roll is finished, the paper roll needs to be pushed out of the paper roll centering device and sent to a packaging station or the next station. Through rotating paper support frame base 2, drive paper support frame 3 and scroll and empty to one side of scroll centering device, the scroll receives the influence of self gravity, rolls out scroll centering device from paper support frame 3 automatically, rolls to packing station or next station.
