dosing kit for metering of additives, such as masterbatch (farbkonzentrat), regenerat and materials or the like

摘要

1. Dosing device for dosing additives such as Masterbatch (colour concentrates) regenerated materials, material which is to be ground, granulates or other easy flowing materials and main materials, to a processing material which is fed to a processing machine by means of a main hopper (11) and a main conveyor worm (13) whereby a neckpiece (10) is provided preferably in between the main hopper (11) and the main conveyor worm (13) and to which at least one dosing device is detachably connected which is equipped with a conveyor worm (3) located inside a cylinder (4), a steplessly adjustable motor (5), whereby the housing (1) of the dosing device is provided with a closable sample extraction orifice (14) which is in alignment with a recess provided in the housing and the conveyor worm (3) discharges the dosed material via a feeding facility through a connecting orifice provided in the neckpiece (10) which is in alignment with the feeding facility into the neckpiece (10), characterized in that, a shut-off device (19, 20) is located in between the feeding orifice (36) of housing (1) and the connecting orifice (40) of the neckpiece (10) which in the one position (X) interrupts the connection from the feeding orifice (36) to the connecting orifice (40) and instead of that establishes a connection of the cylinder chamber (37) of housing (1) to a drainage duct (32) which is connected to a chamber (39) behind the feeding orifice (36) of housing (1), whereas the shut-off device (19) in the other position (Y) releases the connection of the cylinder chamber (34) to the inside of the neckpiece (10), whereby the shut-off device is provided with a slider (19) which is in the form of a hollow box (46) which is only opened on one side to which the profiled pipe of the drainage duct (32) is connected in each position of the slider (19) and that the slider (19) in its closed position forms a seal with an edge area (41) behind a shoulder (42), whereby the upper front wall (29) runs at an obtuse angle (alpha) to the bottom (26) of the slider (19) and this front wall (29) is inclined toward the connecting orifice (40) of the neckpiece (10) whereby the slider (19) is guided in two mutually-perpendicular levels through the slide guides (17, 18 or 33, 38).
