Compared with the prior art, the grinding mechanism can be industrially applied in producing and destroying coins, thus effectively preventing the safety problem existing in the current mode of destroying coins.
Description
Technical field
The utility model relates to a kind of rolling body, is to be used to belong to coinage industry and bank's special-purpose machines and tools technical field.
Background technology
The problem that all exists base cake and flower cake defect ware to destroy at present in the coin production of China.These defect wares finally all need melting to destroy, but melting destroys and need carry out to specific producer, so all can produce safety problem in the process of transportation and destruction.If can be before dispatching from the factory, in the closed job-shop these defect wares being carried out mechanical pins earlier ruins, make it to completely lose the defect ware that the feature of coin obtains, just can be used as the waste disposal of metal, thereby effectively prevent the safety problem that exists in the present Coin destroying mode.Smash that the People's Bank's destruction is taken over and the damaged coin in the circulation, the safe problem of same existence.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model proposes a kind of rolling body, be used for the machine that the surperficial picture and text and the face shaping of the counterfeit money of waste product that the mint is produced and circulation and damaged coin roll, make these coins no longer to have the coin circulation recognition feature, concrete technical scheme is as follows:
A kind of rolling body comprises frame, and frame is provided with main motor, first roller and second roller; Described first roller and second roller rotate in opposite directions, and turning cylinder is parallel; The roll gap of two rollers and quilt are rolled the coin thickness correspondence; Described main motor connects and drives two rollers and rotates.
Be equipped with the gear that corresponding synchronous is rotated on described first roller and second roller, two gears are meshing with each other.Also be provided with corresponding sprocket wheel on first roller and the main motor, main motor drives first roller by driving chain and rotates; For two rollers, the gear on first roller is a driving gear, and the gear on second roller is a driven gear.Described second roller is above the rear flank of first roller, and it is to drop on first roller that coin is entered, and with the motion of first roller, rolls the back and falls naturally.
Also be connected with roll gap adjustment device on described second roller, this adjusting device comprises worm screw, worm gear, eccentric bushing and connecting plate; The turning cylinder of second roller is located in the eccentric bushing; Eccentric bushing is fixed by connecting plate and worm gear; The worm and wheel engagement drives the rotation of turbine by the rotation of worm screw, and then drives the eccentric bushing rotation, drives the eccentric shaft rotation of second roller along eccentric bushing by eccentric bushing, thereby regulates the centre-to-centre spacing between the roller, and corresponding roll gap is along with adjusting.Can conveniently regulate roll gap like this, be applicable to the coin of different-thickness.
Be equipped with scraper with first roller and corresponding position, two roller positions of second roller; The cutting edge of scraper and roller surface are close to.Corresponding two scrapers of each roller, two scrapers are located at the both sides of roll gap respectively; The cutting edge of two scrapers in opposite directions.The cutting edge of each scraper towards with the roller rotation direction in opposite directions, can both scrape coin in roller main story or when counter-rotating like this.Be connected with spring on the described scraper, scraper is subjected to be close to the roller surface behind the spring force.Described roller surface is provided with decorative pattern, and the blade shape of described scraper is corresponding with the lines of roller surface detail.Rolling effect is better like this, and the coin after rolling easily shovel fall and roll banding not.
Described decorative pattern is a plurality of parallel radially triangular groove that the roller surface is provided with, and each triangular groove is trapped among the roller surface along the circumferencial direction of roller, the mutual interlock of the triangular groove on two rollers; The blade shape of described scraper is a zigzag, and sawtooth stretches into triangular groove.
Compared with prior art, the utility model can be applied in to industrialization in coin production and the destruction process, thereby effectively prevents the safety problem that exists in the present Coin destroying mode.
