[0036] Preferably, the multi-layer guide rail 19 is arranged in the main shaft 6; the synchronous belt 13 is located outside the multi-layer guide rail 19; the two ends of the first paper picking rod 2 are respectively located in a multi-layer guide rail 19; a slider 14 is provided at the position of the first paper picking rod 2 close to the multi-layer guide rail 19, and the first paper picking rod 2 is slidably connected to the synchronous belt 13 through the slider 14.

[0037] Preferably, a sensing device 22 is installed on the slider 14; a sensing switch 20 is provided on the multi-layer guide rail 19; and the sensing device 22 and the sensing switch 20 are inductively connected.

[0038] Preferably, the conveying assembly further comprises a driving device 7; the driving device 7 drives the first pulley 17 to rotate.

[0039] Preferably, the conveying assembly further includes a drag chain 23 ; a drag chain groove 21 is provided on the main shaft 6 ; one end of the drag chain 23 is installed in the drag chain groove 21 ; and the other end of the drag chain 23 is connected to one end of the first paper picking rod 2 .

[0040] Specifically, in the multi-stroke paper picking system of this embodiment, a paper folding position is set at a position of the conveying component away from the paper bin 8, and the paper picking component moves back and forth between the paper bin 8 and the paper folding position. The paper picking component clamps the corrugated paper in the paper bin 8 and then transports it to the paper folding position to put down the corrugated paper.

[0041] Specifically, the multi-stroke paper picking system of the present embodiment is provided with a conveying frame surrounded by a main shaft 6 and two slave shafts 5 on the outside of the paper bin 8, and a first paper picking rod 2 and a second paper picking rod 4 with a height difference are provided through a multi-layer guide rail 19; wherein, the synchronous belt 13 sleeved on the first pulley 17 and the second pulley is divided into an upper and lower layer, the upper layer of the synchronous belt 13 and the upper part of the multi-layer guide rail 19 are located at the same height, and the lower layer of the synchronous belt 13 and the lower part of the multi-layer guide rail 19 are located at the same height; the slider 14 of the first paper picking rod 2 is slidably connected to the lower layer of the synchronous belt 13, and the slider 14 of the second paper picking rod 4 is slidably connected to the upper layer of the synchronous belt 13, so that the first paper picking rod 2 located at a lower position is driven by the lower layer of the synchronous belt 13, and the second paper picking rod 4 located at a higher position is driven by the upper layer of the synchronous belt 13. When the synchronous belt 13 moves, one layer of the synchronous belt 13 moves toward the paper bin 8, and the other layer of the synchronous belt 13 moves toward the paper folding position, thereby causing the first paper picking rod 2 and the second paper picking rod 4 to move in opposite directions.

[0042] The driving device 7 of this embodiment includes a motor 18, which is arranged at the connection position of the main shaft 6 and the slave shaft 5. The motor 18 drives the first pulley 17 to rotate, and then the first pulley 17 drives the synchronous belt 13 to work, and the synchronous belt 13 drives the first paper picking rod 2 and the second paper picking rod 4 to work. The movement direction of the synchronous belt 13 of this embodiment is controlled by the forward and reverse rotation of the motor 18. When a paper picking clamp clamps corrugated paper, the motor 18 reverses to make the synchronous belt 13 move in the opposite direction, so that the paper picking rod starts to move away from the paper bin 8.

[0043] Specifically, the first paper picking clamp 1 of the present embodiment is arranged on the first paper picking rod 2, and the first paper picking clamp 1 is engaged or released by the cylinder drive. During the paper picking process of the first paper picking rod 2, when the corrugated paper in the paper bin 8 is sucked by the suction cup assembly 10, the lifting device 9 raises the suction cup assembly 10 to the same height as the first paper picking clamp 1, and the cylinder drives the first paper picking clamp 1 to clamp the corrugated paper sucked by the suction cup assembly 10, and then the motor 18 is reversed to move the first paper picking rod 2 to the paper folding position, and then the cylinder drives the first paper picking clamp 1 to release the corrugated paper and put it into the paper folding position.

[0044] Specifically, two first paper clips 1 are arranged on the first paper picking rod 2 of the present embodiment to ensure the stability of clamping the corrugated paper; meanwhile, two second paper clips 3 are also arranged on the second paper picking rod 4.

[0045] Specifically, the working process of the multi-stroke paper picking system of this embodiment is as follows: the suction cup assembly 10 of the paper bin 8 sucks the corrugated paper in the paper bin 8, and the corrugated paper is lifted to the clamping height by the lifting device 9; the first paper picking clamp 1 is opened, the paper picking rod moves to the edge of the corrugated paper to allow the corrugated paper to enter the paper picking clamp, the paper picking clamp clamps the corrugated paper, and the suction cup of the paper bin 8 stops vacuum suction to release the corrugated paper;

[0046] At the same time, the second paper picking clamp 3 has taken a piece of corrugated paper and dragged it to the paper folding position; the first paper picking rod 2 drags the corrugated paper horizontally along the guide rail to the paper folding position, and the paper picking clamp opens; at the same time, the lifting device 9 has sucked the second corrugated paper to the matching height of the second paper picking clamp 3; the first paper picking clamp 1 puts down the corrugated paper, and at the same time the second paper picking clamp 3 opens and clamps the second corrugated paper; this reciprocating cycle is repeated.

[0047] Specifically, the lifting device 9 of this embodiment is an electric cylinder. The corrugated paper sucked by the suction cup assembly 10 can stay at different paper picking heights under the control of the lifting device 9, ensuring that the height of the sucked corrugated paper matches the height of the paper picking clamps that move to the edge of the corrugated paper. When one group of paper picking clamps moves to clamp the paper, the other group clamps the corrugated paper and drags it to the paper folding position, and the upper and lower groups move simultaneously without interfering with each other, ensuring that the motor 18 is loaded in each stroke, thereby improving the paper picking efficiency.

[0048] Specifically, when the first paper picking rod 2 of the present embodiment moves, it will drive the drag chain 23 to move, and the movement stability of the first paper picking rod 2 is ensured by the drag chain 23 .

[0049] Specifically, the multi-pass paper picking system of this embodiment is controlled by PLC.

[0050] Specifically, the induction switch 20 is set on the guide rail, and the induction device 22 is set on the slider 14 of the paper picking rod. It follows the paper picking rod to make linear reciprocating motion. When the paper picking rod drives the induction device 22 to run near the induction switch 20 and is sensed by the induction switch 20, the induction switch 20 sends a signal to the PLC.

[0051] Specifically, Figure 2 As shown, the conveying assembly of this embodiment is provided with a shield 11 to protect the slave shaft 5, a washer 12 to buffer the impact of the paper picking rod on the guide rail, and a mounting frame 15 for mounting the bearing.

[0052] The multi-pass paper picking system of this embodiment realizes double-pass paper picking by providing two paper picking rods, which can significantly improve the paper picking efficiency.

[0053] The above is a detailed description of an embodiment of a multi-pass paper picking system provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
