ES291502U - Advancement module for sanding machines (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Advance module for sander machines, especially for sanders of moldings, whose purpose is to keep perfectly the molding during the movement of the same towards the sanding head and against the efforts of any direction transmitted to the molding by said head, essentially it is characterized because on the sector of said module in which the conveyor belt is established for dragging the molding, a bridge of u configuration is established, with its concavity oriented downwards and with the ends of its lateral branches fixedly fixed to the chassis of the module, in which two pairs of freewheeling sheaves are located, all of them at the same level, each pair mounted on a common support and out of phase such pairs, both longitudinally and transversally, being in turn the supports of said pairs of sheaves joined together in a single general support, from which ge a vertical arm that plays in the bosom of a bushing with which a captive screw cooperates, assisted by a drive handle, a screw that crosses the middle area of the upper and middle branch of the U-shaped bridge, so that through said handle is adjustable height adjustment for the lower sheaves, intended to press the molding, against the conveyor belt, having foreseen that immediately after this same mechanism, on a rigid support surface and sliding of the molding, a which in turn is solidary another mechanism, this for lateral pressing of the molding that will be repeated as many times as necessary along the module, attacking the molding by one or another of the side faces thereof, mechanism constituted by a pair of parallel and horizontal axes, that emerge laterally from the structural support of the sliding platform of the molding, and on which a helmet double l, provided with a prisoner screw assisted by a drive handle, for locking said bushing with respect to the axes or sliding bars, emerging vertically from that bushing a pair of supports that relate to it with a horizontal plate on which it is mounted with freedom of rotation one or more sheaves with vertical axis, which laterally attack the molding immediately above the rigid sliding platform for it, said sheave or rollers being able to regulate their degree of lateral approach to the longitudinal axis of said platform, by sliding the double bushing on the mentioned guide shafts, after loosening and later tightening the captive screw, acting on the corresponding handle.
