{54) DEVICE FOR CLEANING ELECTROGRAPHIC

one

The invention relates to the field of electrography, namely to devices for cleaning electrographic plates from 1Co-containing powder.

A device for cleaning electrographic nrtacTHH is known, which contains a paper for cleaning, placed on a roller, a paper feed mechanism and mounted on the right carriage for an electrographic plate, 11.

The disadvantage of this device is the inadequate quality of cleaning of electrographic plates.

The aim of the invention is to improve the quality of cleaning.

This goal is achieved by the fact that a device for cleaning electrographic plates, comprising a paper tape for cleaning, placed on an elastic roller, a paper tape feeding mechanism and mounted on a guide carriage for an electrographic plate, has an elastic

PLATES

a roller leash and two shoulders growl mounted on a carriage and connected to the leash.

The drawing shows a kinematic diagram of the device.

The device contains a base I with an axis 2 swing, on which resilient roller 3 is secured, a leash 4, ratchet wheels 5, 6 and a gear wheel 7. On the base there is a feed roller 8

10 with a brake device 9 and a take-up roller 1 O with a gear wheel 11 on the shaft. Ratchet wheels 12 and 13 are mounted on the ratchet wheel 6. The paper tape 14 is wrapped around the carbon roller. Forward 15 are 15 longitudinal movements with the carriage 16. They are installed perpendicular to the swing axis. On the carriage mounted emphasis 17 with lever 18, the entrance is chic in engagement with the leash. A cassette 19 with an electrophotographic plate is fastened in the upper part of the cart.

The device works as follows; zom.

Opia to the movement of the carriage 16 with the cassette 19, the anvil 17 rotates the lever 18, which in turn rotates the lead 4 and together with it the base 1 around the axis 2. The base rotates towards the opposite side of the movement of the cassette 19. Together the sucker 2 turns the ratchet wheel 5 which transmits movement through the ratchet 12 to the wheels 6 and 7. All elements mounted inside the base 1 make a rotation with it around the axis 2 and are fixed relative to each other. The elastic roller 3 with paper tape 14 wrapped around the negation, meeting with the surface of the plate, performs a counter-movement with the paper, collects and removes the powder from the surface. The arms of the lever 18 are selected in such a way that, as the entire surface of the electrophotographic plate passes under the axis 2, the elastic roller 3 together with the base I rotates only at a certain working angle, which ensures the necessary amount of paper.

When the cassette 19 moves backward, the lever 18 rotates the base 1 in the opposite direction, 1 this ratchet 13, installed in the housing, fixes the position of the wheels 6 and 7 and the wheel 11 rolls around the stationary wheel 7. The contaminated section of paper is rewound onto the take-up roller 10. Tension paper tape supports brake device 9.

. The proposed device improves the efficiency of cleaning of electrographic plates, reduces the mechanical wear of the photosensitive layer, is reliable in operation, economical and ipocTO performed.
