Abstract:
Revarnishing machine for easy opening lids, of the type using varnish projection nozzles, a single or double revolving revarnishing head and a lid transporting device, characterized in that it is provided with a revarnishing gun (10), with or without an additional separator (11) of variable thickness depending on the size of lid (12), which applies the varnish to the lids in a circular motion on the diameter of the incision and conical projection of adjustable height, also provided with a lid transporting device with a motor (25) connected to an intermittent wheel race (29) whose outlet shaft (51) provides an intermittent motion to a conveyor chain (46) with pull flaps (47) to varnish lids (12) one at a time, complemented by a drive chain (35) associated to a feeder box (37) which drives a shaft (38) of a lid positioner (39) and a dosing blade (40) which collects and separates the lids arriving from a feeder tower (41) and inserts them in a groove of the positioner (39) which supplies them to the lid transporting device, characterized in that the revolving head is coupled to a support (1) joined to the revarnishing bench and on which is coupled another circular support (4), on the upper part of which is an electric motor (6) which is joined to a toothed pulley (16) by a conical slip (20), the front face of support (4) being open in order to facilitate the toothed belt transmission to other pulleys, wherein the toothed pulley (16) is engaged through a toothed belt (17) to a pulley (13) and a tensor Pulley (14), provided with bearings (22), tensor pulley (14) being connected to a conventional tensor (19) and joined to head support (1) by a shaft or bolt, and in that the toothed belt (17) engages pulley (15) which transmits the motion to a slip (2) with a revolving shaft (3), slip (2) having an opening in its lower front part for the revarnishing gun (10), which is laterally connected to the lower end of shaft (3) with an interposed additional separator (11) of a variable thickness depending on the size of the lid (12) to be varnished.
