Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to a paper rolling machine for papermaking. Background Technology

[0002] According to the patent document with publication number CN222974494U, the paper roller slides into the groove through the roller changing track so that two gears mesh. Then, the paper winding motor drives the paper roller to rotate and wind the paper through gear transmission. After the sensor blocks the paper winding, the hydraulic cylinder supports the paper roll to descend and lets the paper roll fall on the slope and move away. Then the hydraulic cylinder reconnects with the inclined guide rail to start the next paper winding. The patent document describes a paper roll that is stopped during the descent driven by a hydraulic cylinder. Due to the large weight of the paper roll, excessive speed on the slope would create significant inertia and pose a danger. Therefore, the paper roll does not roll too fast on the slope. Once the paper roll leaves the hydraulic cylinder support position, the hydraulic cylinder support needs to move upward to place the paper roll back into the support position before the paper roll can be rolled again. As a result, the entire paper roll operation is relatively cumbersome and the speed of changing paper rolls is slow. Utility Model Content

All electrical components mentioned in this document are electrically connected to an external main controller and 220V AC mains power, and the main controller can be a conventionally known device such as a computer that provides control.

[0016] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-9 As shown, a paper rolling machine for papermaking includes a base 6, with support side plates 4 fixed on both sides of the top of the base 6, and a roller feed frame 7 fixed at one end of the base 6. It also includes two drive mechanisms 1 and two feeding mechanisms 2. The two drive mechanisms 1 are located at one end of the two support side plates 4, and the two feeding mechanisms 2 are located on the side of the base 6 that are close to each other.

[0017] In this embodiment: the drive mechanism 1 includes a limiting frame 15, a lifting cylinder 16 is fixedly mounted on the limiting frame 15, a lifting frame 12 is provided on one side of the limiting frame 15, a drive roller 13 is rotatably connected inside the lifting frame 12, a drive motor 14 is fixedly mounted on the side of the lifting frame 12 extending out of the support side plate 4, a hydraulic cylinder 11 is fixedly mounted on the top of the lifting frame 12, a notch for the drive roller 13 to extend is provided at the lower end of the lifting frame 12, and the fixed part of the hydraulic cylinder 11 is fixedly connected to the upper end of the support side plate 4, a sliding groove for the lifting frame 12 to slide up and down is provided at one end of the support side plate 4, the limiting frame 15 is slidably connected to the inner side of the support side plate 4, the lifting cylinder 16 is fixed to the outer side of the support side plate 4, and the telescopic part of the lifting cylinder 16 is fixedly connected to the upper end of the limiting frame 15. The hydraulic cylinder 11 is used to extend and retract to push the lifting frame 12 downward. At the same time, the lifting frame 12 will drive the drive motor 14 and the drive roller 13 to move downward synchronously along the slide groove of the support side plate 4. At this time, the drive roller 13 inside the lifting frame 12 presses on the end of the paper roll. Then, the drive motor 14 drives the drive roller 13 to rotate inside the lifting frame 12. The rotation of the lifting frame 12 drives the paper roll to rotate on its axis, and the paper can be wound on the roll. In addition, before the drive roller 13 drives the roll to rotate, the lifting cylinder 16 retracts and drives the limit frame 15 to move downward and abut against the top of the base 6. Then, the lower end of the limit frame 15 blocks the feeding mechanism 2 to prevent movement during the paper rolling process.

[0018] In this embodiment: the feeding mechanism 2 includes a chain 22, with sprockets 21 meshing at both ends of the inner side of the chain 22. Two placement seats 24 are provided on the outer side of the chain 22. Each placement seat 24 is connected to the chain 22 via a connecting frame 23. Two auxiliary rollers 25 are rotatably connected to the inner side of the placement seat 24. The chain 22 is rotatably connected to the base 6. A damping motor 5 for driving the chain 22 to rotate is provided at the end of the base 6 away from the limiting frame 15. An annular groove for moving the chain 22 is provided on the inner side of the base 6 near the supporting side plate 4. Two limiting plates are fixed on the side of the placement seat 24 near the annular groove. The connecting frame 23 has a T-shaped structure and is close to the chain 22. One end of the mounting bracket 23 has a pin hole for the chain pin to pass through. A positioning horizontal shaft is fixed to the end of the connecting bracket 23 away from the chain 22. Both limiting plates of the placement seat 24 have arc-shaped slots for the positioning horizontal shaft to pass through. Multiple support rollers 3 are rotatably connected to both sides of the placement seat 24. The damping motor 5 drives the corresponding sprocket 21 to rotate, which in turn drives the chain 22 to rotate within the annular groove of the base 6. The connecting bracket 23 connects the chain 22 and the placement seat 24, thus causing the two placement seats 24 to move along the outside of the annular groove during the rotation of the chain 22. Simultaneously, the support rollers 3 on both sides of the placement seat 24 reduce the movement during this process. Friction, in addition, the two limiting plates of the placement seat 24 will slide in the annular groove to prevent the placement seat 24 from disengaging from the annular groove. During this process, when any one of the placement seats 24 moves to one end of the chain 22, the roller shaft in the roller feed frame 7 will slide into the inner side of the placement seat 24 at one end of the chain 22. At this time, as the placement seat 24 flips upward, the chain 22 will be flipped up by the two placement seats 24 and placed above the chain 22. At this time, the two auxiliary rollers 25 in the placement seat 24 provide rolling support to the end of the roller shaft. Then, as the chain 22 rotates, the two placement seats 24 are positioned below the two lifting frames 12. Then, the limiting frame 15 moves downward so that its lower end abuts against the side of the placement seat 24. After the damping motor 5 stops rotating, when the paper roll is finished winding on the roller, the rotating part of the damping motor 5 drives the sprocket 21 to make the chain 22 continue to rotate. At this time, the roller with paper wound on the outside of the chain 22 will slide from one side to the other side along the top of the base 6. At the same time, the placement seat 24 on the outside of the chain 22 without roller will move to one end of the chain 22 and repeat the above action of putting in the roller. When the new roller moves to the bottom of the lifting frame 12 along with the two placement seats 24, the other two placement seats 24 will move to the other end of the chain 22 and flip over. Then the roller with the paper roll will roll off the two placement seats 24 and fall onto the corresponding conveyor belt, and be sent out with the conveyor belt.

[0019] Working Principle: In use, the device is first placed on the paper production line where paper needs to be wound. When the paper begins to be wound, the damping motor 5 drives the corresponding sprocket 21 to rotate. The rotation of the sprocket 21 drives the chain 22 to rotate within the annular groove of the base 6. The connecting frame 23 connects the chain 22 and the placement seats 24. As the chain 22 rotates, it drives the two placement seats 24 to move along the outside of the annular groove. Simultaneously, the support rollers 3 on both sides of the placement seats 24 reduce friction during movement. Furthermore, the two limiting plates of the placement seats 24 slide within the annular groove to prevent the placement seats 24 from disengaging. During this process, when any one of the placement seats 24 moves to one end of the chain 22, the roller shaft in the roller feed frame 7 slides into the inner side of the placement seat 24 at one end of the chain 22. As the placement seats 24 flip upwards, the chain 22 is lifted by the two placement seats 24 and placed above the chain 22. At this time, the two auxiliary rollers 25 inside the placement seats 24... Rolling support is provided at the ends of the roller shaft. Then, as the chain 22 rotates, the two placement seats 24 are positioned below the two lifting frames 12. The extension and retraction parts of the hydraulic cylinder 11 push the lifting frame 12 to move downward. At the same time, the lifting frame 12 drives the drive motor 14 and drive roller 13 to move downward synchronously along the slide groove of the support side plate 4. At this time, the drive roller 13 inside the lifting frame 12 presses against the end of the paper roll roller shaft. Then, before the drive roller 13 drives the roller shaft to rotate, the extension and retraction parts of the lifting cylinder 16 retract and drive the limit frame 15 to move downward and abut against the top of the base 6. Then, the lower end of the limit frame 15 blocks the side of the placement seat 24 to prevent movement during the paper roll process. At the same time, the damping motor 5 stops rotating. Then, the end of the paper to be rolled is glued to the outside of the roller shaft. Then, the rotating part of the drive motor 14 drives the drive roller 13 to rotate inside the lifting frame 12. The rotation of the lifting frame 12 drives the paper roll roller shaft to rotate around its axis, and the paper can be rolled onto the roller shaft. When the paper roll is wound on the roller, the damping motor 5 drives the sprocket 21 to make the chain 22 continue to rotate. At this time, the roller with paper wound on the outside of the chain 22 will slide from one side to the other along the top of the base 6. At the same time, the placement seat 24 on the outside of the chain 22 without roller will move to one end of the chain 22 and repeat the above action of putting in the roller. Then, the new roller can be driven by the drive roller 13 to continue to wind the paper. In addition, when the new roller moves to the bottom of the lifting frame 12 with the two placement seats 24, the other two placement seats 24 will move to the other end of the chain 22 and flip over. Then the roller with the paper roll will roll off the two placement seats 24 and fall onto the corresponding conveyor belt, and be sent out with the conveyor belt.
