[0002] Paper is typically rolled up and stored in rolls after production. However, since paper is used for writing, drawing, printing, packaging, and other everyday items, it needs to be cut into smaller rolls to the required dimensions before production. Conventionally, slitting machines cut individual rolls of paper, but this method is relatively inefficient. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a dual-path rotary slitting machine.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a dual-path rotary slitting machine, including a conveyor frame, a first paper roller rotatably mounted at the front of the conveyor frame, a second paper roller rotatably mounted at the middle of the conveyor frame, a slitting device connected to the output end of the conveyor frame, a plurality of first transition rollers arranged between the first paper roller and the slitting device, a plurality of second transition rollers arranged between the second paper roller and the slitting device, a paper pressing and conveying assembly installed at the output end of the slitting device, and a receiving device installed at the output end of the paper pressing and conveying assembly.

[0005] Preferably, the slitting device includes a slitting frame and a paper cutting roller, the paper cutting roller being rotatably mounted on the slitting frame, and a cutter being mounted on the paper cutting roller.

[0006] Preferably, the paper pressing and conveying assembly includes an active paper pressing roller and a driven paper pressing roller, with multiple paper pressing belts sleeved between the active paper pressing roller and the driven paper pressing roller, and a tensioning roller disposed between the active paper pressing roller and the driven paper pressing roller.

[0007] Preferably, the front end of the slitting device is equipped with a plurality of staggered paper guide rollers.

[0008] Preferably, a rubber roller is provided on the front side of the input end of the paper cutting roller.

[0009] Preferably, the receiving device includes a receiving rack, a receiving conveyor, and a receiving platform. One end of the receiving conveyor is rotatably mounted on the slitting rack. The receiving rack is equipped with a lifting assembly that controls the lifting and lowering of the other end of the receiving conveyor. The receiving platform is movably mounted on the receiving rack and is located on one side of the output end of the receiving conveyor.

[0010] Compared with the prior art, the present invention has the following advantages: the dual paper path rotary slitting machine can slit two rolls of paper at the same time by setting up dual paper paths, which effectively improves the production efficiency of paper slitting.

[0013] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0014] like Figure 1 As shown, a dual-path rotary slitting machine includes a conveyor frame 1. A first paper roller 2 is rotatably mounted at the front of the conveyor frame 1, and a second paper roller 3 is rotatably mounted at the middle of the conveyor frame 1. A slitting device 4 is connected to the output end of the conveyor frame. A plurality of first transition rollers are arranged between the first paper roller 2 and the slitting device, and a plurality of second transition rollers are arranged between the second paper roller and the slitting device 4. A paper pressing and conveying assembly is installed at the output end of the slitting device 4, and a receiving device is installed at the output end of the paper pressing and conveying assembly.

[0015] In this embodiment, the slitting device 4 includes a slitting frame 5 and a paper cutting roller 6. The paper cutting roller 6 is rotatably mounted on the slitting frame 5, and a cutter is mounted on the paper cutting roller 6.

[0016] In this embodiment, the paper pressing and conveying assembly includes an active paper pressing roller 7 and a driven paper pressing roller 8. Multiple paper pressing belts are sleeved between the active paper pressing roller 7 and the driven paper pressing roller 8, and a tensioning roller is provided between the active paper pressing roller 7 and the driven paper pressing roller 8.

[0017] In this embodiment, the front end of the slitting device 4 is equipped with a plurality of staggered paper guide rollers 9.

[0018] In this embodiment, a rubber roller 10 is provided on the front side of the input end of the paper cutting roller 6.

[0019] In this embodiment, the receiving device includes a receiving rack 11, a receiving conveyor 12, and a receiving platform 13. One end of the receiving conveyor 12 is rotatably mounted on the slitting frame 5. The receiving conveyor 12 is equipped with a conventional paper conveyor. The receiving rack 11 is equipped with a lifting assembly that controls the lifting and lowering of the other end of the receiving conveyor. The lifting assembly consists of several lifting cylinders symmetrically mounted on both sides of the receiving conveyor. The lifting cylinders are conventional lifting cylinders. The cylinder body of the lifting cylinder is hinged to the receiving rack 11, and the piston end of the lifting cylinder is hinged to the receiving conveyor 12. The receiving platform 13 is movably mounted on the receiving rack 11. The receiving platform 13 is located on one side of the output end of the receiving conveyor 12. The receiving rack 11 is equipped with a transverse cylinder that drives the receiving platform 13 to move. A baffle is installed on the side of the receiving platform 13 away from the receiving rack 11. The baffle can be used to flatten and align one side of the paper, so the operator only needs to tidy up the other side of the paper.

[0020] During operation, when the paper arrives at the receiving conveyor 12, the transverse cylinder controls the receiving platform 13 to move below the receiving conveyor 12, and then the lifting cylinder controls one end of the receiving conveyor to descend, so that the paper arrives on the receiving platform 13. The receiving platform 13 moves with the paper, so that the paper can be stably and aligned on the receiving platform 13.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall be within the scope of the present utility model.
