When the portable bill storage device is used, the shell 3 can be held by a hand, when the guide shell 22 is not installed, for example, bills are placed on a table surface and need to be destroyed, the shell 3 is held by the hand, the rear portion of the shell is inclined upwards, the front portion of the feed roller 1 is exposed out of the shell 3, the feed roller 1 is pressed at one end of the bills, meanwhile, the front end of the guide plate 16 contacts the table surface, the front end of the guide plate 16 is pointed, the bills are conveniently shoveled from the end portions, the shell 3 is manually pushed forwards and kept pressed, the feed roller 1 rolls over the upper surface of the bills, and in the rotating process of the feed roller 1, the surface of the printing cylinder 5 carries dye to cover and coat the surfaces of the bills, so that the handwriting on the surfaces of the bills cannot be directly recognized, and the privacy effect is achieved. Bills enter between the feed roller 1 and the paper shredding roller 2 from the space between the feed roller 1 and the guide plate 16, the cutting knives 6 on the paper shredding roller 2 can be uniformly distributed at intervals along the axial direction of the paper shredding roller 2, the printing cylinder 5 is used as a support, the cutting knives 6 cut the bills into strips, meanwhile, when the serrated paper shredding knives 7 are contacted with the printing cylinder 5, the bills are squeezed and inserted, under the differential rotation, the linear speed of the rotation of the paper shredding knives 7 is higher than the entering speed of the bills, the tearing effect is formed, the bills are torn, the plurality of paper shredding knives 7 can be distributed at different positions along the circumferential direction of the paper shredding roller 2, different angles and the like, the bills are torn and destroyed, after the serrated paper is inserted into the bills, the stripped bills can be split into a plurality of sections when being torn, the boundary of the paper shredding sections is in a tearing shape and is not easy to splice, each paper shredding knife 7 is provided with a plurality of serrated teeth, a part of the bills is dug out with probability, a particle part is formed and separated, the destruction degree of the bill is less prone to be recovered or relevant information is less prone to be read. After the bills are crushed by the paper crushing roller 2, the bills enter the discharging space in the shell 3, and when the bills need to be poured out, the bills can be discharged outside by opening the sealing door 18.

The feed roller 1 is provided with a scraper 17, and the scraper 17 can clean paper shreds possibly attached or carried on the printing cylinder 5. The cartridge 13 is filled with liquid dye and can be stored in the sponge 14 through the weep hole 15, the printing cylinder 5, while rotating, carries the dye and the ticket is subsequently coated. The surface of the printing cylinder 5 can be provided with printing patterns, so that the interference effect is better realized.

The machine shell 3 is held by hand, when the feeding roller 1 is in rotary contact with bills, the rotation of the feeding roller 1 when moving forwards is the power for shredding paper, the shredding roller 2 is driven to rotate through the meshing transmission of the driving gear 9 and the follow-up gear 10, and the shredding roller 2 and the feeding roller 1 rotate reversely. When the tail of the bill enters between the feeding roller 1 and the guide plate 16, the desktop is free of bills, if the desktop can be dyed (for example, the desktop is provided with a cushion), the machine shell 3 can still be continuously pushed to move forwards to form power, so that the tail of the bill can continuously enter between the feeding roller 1 and the paper shredding roller 2 and be broken and destroyed. When the feeding roller 1 moves to the tail of the bill, the following operations can be adopted to avoid the printing cylinder 5 from dyeing the desktop, the shell 3 is flatly placed, the rotating wheel 11 is made to contact the desktop, the feeding roller 1 is separated from the desktop at the moment, then the shell 3 is continuously pushed forwards, the rotation of the rotating wheel 11 is used as power, the driving gear 12 and the follow-up gear 10 are meshed for transmission, the paper shredding roller 2 and the feeding roller 1 are driven to continuously rotate in a reverse differential mode, and the entering and paper shredding operations of the bill are continuously completed. Through the cooperation of printing section of thick bamboo 5 and deflector 16, the bill also can be paintd by printing section of thick bamboo 5 when the deflector 16, and then the bill tip enters into between feed roller 1 and the deflector 16 after, casing 3 utilizes the output that rotates wheel 11 and accomplish power, realizes the shredded paper operation.

The liquid filled in the cartridge 13 may be ink, and the upper side of the cartridge 13 may be provided with a sealed liquid feeding port. The weep holes 15 may be provided in plural and evenly distributed in the left-right direction to facilitate the adsorption of dye within the sponge 14 and to provide sufficient dye to each printing cylinder 5. When not in use, the bottom end of the machine shell 3 can be placed upwards.

The cooperation of shredded paper roll 2 rear sets up brush 19, and the brush hair of brush 19 can contact with shredded paper sword 7 at rear, and when shredded paper roll 2 rotated, brush 19 casing 3 cleaned shredded paper sword 7, and the shredded paper that probably carries on the messenger shredded paper sword 7 drops to storage space 4 in.

The hexagonal socket 20 is arranged on the rotating wheel 11, so that external power, such as a hexagonal wrench, can be conveniently matched, or the hexagonal wrench is arranged at the output end of the motor to realize power transmission, and the paper shredding operation can be more quickly realized. Meanwhile, the feeding device can be used together with a sucking disc 8 at the rear end of the machine shell 3, the machine shell 3 is erected on a table top through the sucking disc 8, the feeding roller 1 is arranged above the machine shell, and the feeding roller 1 and the paper shredding roller 2 can be driven to rotate through external power.

The lower portion of the front end of the right side wall of the machine shell 3 is provided with the blade 21 which can be used for cutting bills, dividing larger bills and being capable of being used synchronously with paper shredding operation, the feeding roller 1 rolls on the bills, when the bills are pushed forwards, the blade 21 cuts the bills outside the machine shell 3 along the pushing direction, and then the large bills can be smashed in batches. It is of course also possible to use the blade 21 directly to first cut large notes.

The cutting blade 6 is of a disc-type saw-tooth shape, the structure of which is understood by a person skilled in the art and which is not illustrated in the drawings.

The driving gear 9 is positioned at one side of the machine shell 3, and an encapsulation shell can be arranged to seal the gear transmission part, so that the machine shell is more beautiful and safe, and the main structure is clearly shown in the attached drawings, and the encapsulation shell is not arranged.

When installing guide shell 22, guide shell 22 accessible buckle structure etc. are pegged graft and are installed in the casing 3 front portion, there is the clearance between guide shell 22 upper portion and the casing 3 front end, promptly for the bill inlet port, the bill is placed behind this clearance, the bill is located between guide shell 22 and feed roller 1 promptly, and contact with feed roller 1, when advancing through promoting casing 3, when runner 11 rotates, can drive feed roller 1 and shredded paper roller 2 reverse rotation and carry out the shredded paper work, along the direction of guide shell 22 and to deflector 16, the bill is rolled by feed roller 1 and is brought into between shredded paper roller 2 and feed roller 1, destroy. When the guide shell 22 is installed, the suction cup 8 and the groove 20 can be matched for use, the machine shell 3 is vertically fixed on a desktop, and external power is utilized to transmit power through the groove 20. The guiding shell 22 can also be used as a packaging mechanism to wrap the front part of the machine shell 3, thereby being convenient for carrying.
