after entering the paper storage mechanism 4, the paper tape passes under the first auxiliary adjustment roller 441, passes through the bottom set of paper passing rollers and passes through the right side of the small paper passing roller 431, passes through the bottom set of adjustment rollers and passes through the left side of the large adjustment roller 423, passes through the right side of the small paper passing roller 431 in the middle, passes through the left side of the large adjustment roller 423 in the middle, reaches the small paper passing roller 431 in the top, passes through the large adjustment roller 423 in the top, passes through the right side of the second auxiliary adjustment roller 442 located on the upper side of the set of adjustment rollers, passes through the middle adjustment roller 422 in the top, the middle paper passing roller 432 in the middle, and the middle adjustment roller 422 in the bottom, passes through the right side of the large paper passing roller 433 in the bottom, passes through the left side of the small adjustment roller 421 in the bottom, passes through the right side of the large paper passing roller 433 in the middle, passes through the left side of the small paper passing roller 421 in the middle, and passes through the small paper passing through the left side of the small adjustment roller 421 in the middle, then bypasses the right side of the top large feed roller 433, goes out of the top small dancer 421, bypasses the third auxiliary dancer 443, and finally reaches the working machine.

When the piston rod of the tension cylinder 341 retracts and the tension floating roller 34 falls to the lowest position, the tension of the paper tape is controlled by the cooperation of the paper storage frame 41 and the working machine, the working machine pulls the paper tape to run, each adjusting roller 42 can transversely slide under the action of the paper tape acting force to change the position of the adjusting roller, and the paper storage mechanism 4 is gradually compressed towards the middle; this technical scheme structural scheme is simple compact, and the paper storage capacity is stronger, and storage space can also enlarge for it still has a lot of papers to lead to the working machine to trade the paper clearance, brings more time for changing the roll paper, has increased and has traded the paper success rate.

The implementation principle of the embodiment is as follows: when the upper roll paper 11 is about to be used up and the paper receiving machine is ready for receiving paper, the working machine continues to operate; the electric cabinet applies a braking voltage value to a paper tube brake where the running upper paper roll 11 is located until the paper tube brake completely brakes the running upper paper roll 11, and meanwhile, the rubber roller 33 abuts against the accelerating roller 32 to reduce the speed of the paper tape until the paper tape stops, at the moment, the piston rod of the tension cylinder 341 retracts, and the tension floating roller 34 falls to the lowest position; the tension of the paper tape is matched with a working machine by virtue of the adjusting roller 42, the working machine pulls the paper tape to operate, the electric cabinet controls the adjusting roller 42 to slowly move transversely in the direction of the paper passing roller 43, the electric cabinet immediately sends an instruction to cut the upper roll paper 11, the rotating arm is rotated, and new roll paper operates; then, the tension floating roll 34 is lifted up, and the electric control box outputs control voltage to a paper tube brake on the lower roll paper 21 according to a new signal transmitted by the angular displacement potentiometer so as to control the tension of a new paper tape; the new paper tape maintains the uniform paper feeding speed again under the combined action of the tension of the working machine and the braking force of the brake.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
