Abstract
A cogged-belt drive device for drawing along mobile flats of flat cards, in which the cogged belts are equipped, in their development facing the flat guides, with scraping or cleaning elements that eliminate the accumulation of foreign bodies from the guides on which the resting elements of the card flats are drawn along.
Claims13
A device for preventing the deposit of foreign bodies on guides (10) of flats (7) said device comprising a drive system for moving the flats (7), which includes guide wheels, having toothed gears (9) and a cogged belt having an inner surface and an outer surface(23), said inner surface is equipped, with one or more scraping or cleaning elements (40, 41, 42) that eliminate the accumulation of foreign bodies from the guides (10)by direct contact of the scraping or cleaning elements (40,41,42) with the guides (10), on which the resting elements of the flats (7) are moved, additionally said outer surface of said cogged belt is equipped with equally spaced raised protuberances (24) for interacting with toothed gears from a cogged belt driving mechanism, each raised protuberance being separated from one another by lower portions (25).
The device for preventing the deposit of foreign bodies in guides (10) of flats (7) according to claim1, wherein the cleaning elements comprise a scraping element (42), consisting of a plurality of rubber studs (42) arranged in a radial direction.
The device for preventing the deposit of foreign bodies on guides (10) of flats (7) according to claim1, wherein the scraping or cleaning element (40, 41, 42) are attached to said inner surface of the cogged belt (23) at a position that corresponds to the raised protuberances located on the outer surface of said cogged belt(23) as well as corresponding to the position of a flat (7), and said raised protuberances all perform both a functi0on of constraint with the flats and the function of interacting with a cogged belt driving mechanism to progress the scraping or cleaning element (40, 41, 42) along the guide (10) by means of the raised protuberances and lower portions forming a structure that receives a gear tooth from a cogged belt driving mechanism.
