The working principle of the utility model is as follows:
firstly, preparation work before starting equipment:
1. and (3) mounting the corrugated paper core 4 to the first rewinding station I and the second rewinding station II in advance, wherein glue is arranged on the surface of the corrugated paper core 4.
2. And (5) guiding paper to establish a paper path. The corrugated paper sequentially passes through the deviation correcting mechanism 25, the lower part of the press roller 22 and the second carrier roller 127 and is finally stuck on the corrugated paper core 4 on the second rewinding station II.
Secondly, the process flow of the automatic rewinding device during working is as follows:
as shown in fig. 1, the apparatus is started, the second rewinding motor 124 at the second rewinding station II starts to operate, and the cutting unit starts to enter the ready state when the second ultrasonic monitor 125 detects that the diameter of the corrugated paper roll 5 is about to reach the set value. Firstly, starting a triangular plate limiter 35 and a compression roller limiter 24; after the action of the limiter is finished, the compression roller is started (the compression roller 22 is pushed by the compression roller driving cylinder 23, and a certain gap is reserved between the compression roller 22 and the paper core 4 on the first rewinding station I under the action of the compression roller limiter 24); the triangle board 33 of the paper cutting unit acts (driven by the triangle board driving cylinder 34), and after the triangle board 33 is in place, the cutter 31 acts (the cutter driving cylinder 32 pushes the swing arm of the cutter 31, and a certain gap is left between the cutter 31 and the conveyed corrugated paper due to the action of the triangle board stopper 35).
When the second ultrasonic monitor 125 detects that the roll diameter of the corrugated paper roll 5 reaches the set value, the two sets of stoppers (the triangular plate stopper 35 and the press roll stopper 24) are released simultaneously, and because the cutter driving cylinder 32 and the press roll driving cylinder 23 are always in the ventilation state, a large impact force is generated at the moment of release, the cutter 31 cuts the corrugated paper behind the press roll 22, and simultaneously the press roll 22 presses the broken paper on the paper core on the first rewinding station I. The first rewind motor 114 has been activated before the stop is released. After the new paper roll is rewound for 1 circle, the compression roller 22 retreats, and after the compression roller 22 returns to the initial state, each mechanism starts to reset. When the mechanisms reset, the second arm opening and closing driving motor 123 on the support 13 operates to open the second clamping arm 121 corresponding to the second rewinding station II, the paper core 4 is separated from the pressing mechanical clamping jaw on the second rewinding station II, the corrugated paper roll 5 is unloaded by the manipulator, a new corrugated paper core 4 is installed, and glue is coated on the corrugated paper core 4. When the rewound corrugated paper roll 5 completely leaves the rotation range of the bracket 13, the two-station rewinding assembly starts to act, and the new corrugated paper core 4 is turned to the position of the original first rewinding station I. The original first rewinding station I is turned to the position of the second rewinding station II, the corrugated paper core 4 is always used for rewinding the corrugated paper in the turning process, the paper cutting unit enters a preparation state before the diameter of the corrugated paper roll 5 reaches a set value, and automatic corrugated paper rewinding without stopping can be achieved according to the circulation of the steps. In the whole rewinding process, the roll diameter of the corrugated paper roll 5 is detected in real time by ultrasonic waves, the rotating speed of the motor is converted through the change of the roll diameter, and the constant speed of the corrugated paper is realized in this way during rewinding.
The embodiments described above are intended to facilitate the understanding and use of the invention by those skilled in the art. It will be readily apparent to those skilled in the art that various modifications to these embodiments may be made, and the generic principles described herein may be applied to other embodiments without the use of the inventive faculty. Therefore, the present invention is not limited to the above embodiments, and those skilled in the art should make improvements and modifications within the scope of the present invention according to the disclosure of the present invention.
