The roller hook plate drives the roller hook plate to roll backwards along the upper inclined surface of the guide rail rear stop block;

c. when the smooth roll rolls to the front 1/3 stroke of the rear baffle of the guide rail, the smooth roll is connected to the connecting rod side plate of the four-bar mechanism from the curve of the rear edge of the turning roll swing arm to continue rolling, and the smooth roll rolls to the rearmost end of the connecting rod side plate along the inclined surface of the connecting rod side plate;

d. when the detection smooth roll rolls to the position of the rearmost end of the connecting rod side plate, the air cylinder retracts, the air cylinder piston rod retracts to a zero position to drive the connecting rod side plate of the four-bar mechanism to descend, and finally the detection smooth roll steadily falls onto the guide surface of the paper storage frame part, so that one roll turning action is completed;

4. at the moment, the front end curve of the turning roll turning swing arm is always propped against the light paper roll which is rolled in later, so that the phenomenon that a turning roll hook plate is blocked when the turning roll swing arm turns back and forth is avoided, and continuous turning can be realized;

5. repeating the steps 2 to 4, and sequentially cycling.

More specifically, the flow of the water needle cutting is as follows:

1. the water needle cutting mechanism comprises: when receiving the tail paper roll positioning completion signal, the water needle descends from an initial position under the drive of the servo electric cylinder and simultaneously drives the transverse moving mechanism to reciprocate (compressed air is introduced into the high-pressure water/air pipe which is supplied in the water needle after filtration, and the cut tail paper is firstly blown off by the air blowing pipe and then separated by the paper separating head and the separator;

after cutting, the water needle returns to the initial position under the drive of the transverse moving mechanism, and one cycle is completed;

2. and the transverse moving mechanism comprises: under the drive of a servo motor, the water needle cutting mechanism is controlled by a program and is reciprocated by a chain wheel and chain mechanism.

In particular, as shown in fig. 11, the workflow of the movable paper holder is as follows:

1. when the first roll is turned over to the front of the Man Guang paper roll of the paper storage rack unit, the AGV moving trolley enters the bottom of the paper storage rack to stand by

2. When the paper storage rack unit is fully loaded with the paper polishing rollers, the AGV moving trolley bearing plate ascends to support the movable paper storage rack, moves out of the paper storage rack unit and is integrally conveyed to the paper polishing roller storage place;

3. after the light paper roll is unloaded to the storage position, the AGV moving trolley carries the empty movable paper storage frame and returns to the automatic tail paper cutting roll turning machine to wait for the next running paper roll;

4. and repeating all the steps, and sequentially cycling, so that all automation is realized.

The embodiments of the present application have been described in detail above with reference to the accompanying drawings, but the present application is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the application, and yet fall within the scope of the application.
