Patent number: 10265649Abstract: A discharge method and a discharge device for a cleaning device (2) for filters (5, 6), includes a supply line (26) which can be connected to a collection region (23) for removed filter residue (9) of the cleaning device (2). The discharge device (3) has a controllable metering device (4) which adjoins the supply line (26) and which blocks the supply line (26) and receives removed filter residue (9) from the supply line (26) in portions (35) in a meterable manner and discharges same at a different location. For this purpose, the metering device (4) has a metering element (28) which can be moved in a controllable manner, in particular a rotatably and/or movably arranged metering element. The filter residue (9) can be removed from the filter (5, 6) via a backflushing process or in a mechanical manner using a scraper or the like.Type: GrantFiled: June 18, 2014Date of Patent: April 23, 2019Assignee: ETTLINGER KUNSTSTOFFMASCHINEN GMBHInventors: Roderich Ettlinger, Thorsten Ettlinger

Patent number: 7824544Abstract: The invention relates to a device which is used to continuously filter material mixtures, in particular for separating impurities from plastic melts. The device includes a hollow cylindrically-shaped filter element (2) which is arranged inside a housing (1), an annular chamber (22) which is defined from the outside of the filter element (2) and an inner wall of the housing, and at least one stripper (23) which can be pressed onto the filter body by an adjusting device. The stripper is used to remove the impurities detained on the filter element (2) due to a relative movement of the filter element (2) and the stripper (23). The adjusting device contains a pressure sensor (42, 53) which is used to detect the pressure of the material mixture upstream from the filter body and an actuator (43) which is connected to the pressure sensor, the actuator being used to adjust the pressure of the stripper (23) according to the pressure detected by the pressure sensor.Type: GrantFiled: October 23, 2004Date of Patent: November 2, 2010Assignee: Ettlinger Kunststoffmaschinen GmbHInventor: Roderich Ettlinger

Patent number: 7124895Abstract: A device for the continuous filtration of material blends, in particular for separating impurities from plastic melts. A housing has a hollow cylindrical filter disposed inside. An inside chamber is disposed inside the filter. An annular chamber is defined by the outer surface of the filter and an inside wall of the housing. A cleaning device removes the impurities retained on the filter by a motor driving about an axis coupled to pivot the filter inside the housing. The cleaning device has at least one wiper for removing in the radial direction impurities retained on the filter. A conveying device transports off the impurities removed from the filter by the wiper. The motor-driven filter and the conveying device are driven separately of each other.Type: GrantFiled: December 21, 2004Date of Patent: October 24, 2006Assignee: Ettlinger Kunststoffmaschinen GmbHInventor: Roderich Ettlinger

Patent number: 6824382Abstract: A closing unit with rigidly mounted supporting rails (2), a stationary (6) and a movable (12) clamping plate, has a pivot bearing (14, 15) behind each of these clamping plates (6, 12). A closing drive (23) is hinged in these pivot bearings (14, 15) so that it can freely move between said pivot bearings (14, 15) and the closing forces exercised by the closing drive (23) can exercise no bending moment on the machine frame (2, 3).Type: GrantFiled: February 28, 2002Date of Patent: November 30, 2004Assignee: Ettlinger Kunststoffmaschinen GmbHInventor: Martin Ganz

Patent number: 6530777Abstract: An injection moulding machine for producing small plastic components with a drive unit (6, 84), a plasticizing device (4, 42) and a hot channel nozzle (1) having a collection chamber (10) for the molten plastic. An injection ram (35) projects into the hot channel nozzle (1) and can push the collected plastic out. In an embodiment, the plasticizing device (4, 42) and the drive unit (6, 84) are secured to a movable bearing housing (85) and can move the injection ram (35).Type: GrantFiled: July 8, 1999Date of Patent: March 11, 2003Assignee: Ettlinger Kunststoffmaschinen GmbHInventors: Martin Ganz, Paul Sillman
