Disclosed is a powdery material filling device with a redundant (i.e., excess or waste) powdery material recovering mechanism. The powdery material filling device may be used in a rotary compression molding machine. In certain aspects, the redundant powdery material recovering mechanism is capable of actively recovering and reusing a redundant (i.e., excess or waste) powdery material even upon production of multi-layer tablets.

A molded product discharge device includes a rotary member configured to be horizontally rotatable and disposed to be partially overlapped from above with a die table including a die bore of a rotary compression molding machine, a pocket bore provided in the rotary member, extending in a radial direction of the rotary member to be larger than an inner diameter of the die bore, and including a radially outside edge closed or narrowed to be opened smaller than an outer diameter of the molded product, for receiving and capturing the molded product pushed upward from the die bore by the lower punch when the pocket bore passes above the die table, and a support member supporting from below the molded product captured by the pocket bore.

A liner for a ram configured to press a viscous material. The liner includes a liner wall and a circumferential lip. The liner wall is configured to abut a ram plate of the ram and includes a number of apertures configured to align with apertures of the ram plate. The liner wall and circumferential lip are configured to prevent the viscous material from contacting a ram surface and circumferential surface of the ram plate, thus making the ram easier to clean.

A crimping system includes a base, a fixing device, and a waste recycling device. The base defines a throwing port that allows waste materials to pass through. The fixing device is fixedly installed on the base and adapted to fix a flexible flat piece. The crimping device is movably installed on the base and is movable in two perpendicular, horizontal directions. The crimping device is adapted to crimp a terminal onto the flexible flat piece when it is moved to a predetermined crimping position aligned with the crimping part on the flexible flat piece. The waste recycling device is fixedly installed on the crimping device and moves synchronously with the crimping device. The waste recycling device is adapted to recover waste materials generated during crimping of the terminal, and to eject recovered waste materials through the throwing port when it is moved to a predetermined position aligned with the throwing port.

A rotary press (10), in particular a rotary tablet press, includes a rotor (14) rotatable about an axis of rotation (12) and a cleaning device (16) for cleaning the rotary press (10). The cleaning device (16) includes at least one spray opening (18), in particular a plurality of spray openings (18), for spraying a cleaning agent (20). The cleaning device (16) is coupled to the rotor (14) and configured such that the spray opening (18) can be rotated about the axis of rotation (12) by rotating the rotor (14). A method for cleaning such a rotary press (10) is also described.

The invention relates to a scraping device for a rotary tablet press comprising a scraper that is designed to scrape off material for pressing that is located on the top side of a die plate of the rotary tablet press, the die plate rotating relative to the scraper, and comprising a force-generating apparatus that is designed to press the scraper with a predetermined compression against the top side of the die plate, characterized in that the force-generating apparatus comprises a fluid pillow filled with a fluid that is in contact with the scraper directly or via at least one transmission element in order to press the scraper by the predetermined compression against the top side of the die plate. The invention also relates to a rotor for a rotary tablet press, as well as a rotary tablet press.

A mixed collection and compression device for dust and thin metal includes a separation mechanism used to sieve a flowing gas therein into a dust-containing gas and a metal material; a filtering mechanism connected to the separation mechanism and used to filter dust in the dust-containing gas; an inert powder adding mechanism connected between the separation mechanism and the filtering mechanism and used to add inert powder into the dust-containing gas during transportation; a compression mechanism connected to the separation mechanism and used to collect and compress the metal material; and a power gas source used to provide a negative pressure environment for a gas inside the separation mechanism to make the gas sequentially pass through the separation mechanism, the inert powder adding mechanism, and the filtering mechanism. It has the effects of reducing the explosion risk and improving the safety of field work.

A rotary tablet press comprising a filling device and a support assembly The rotary tablet press (1) comprises a housing (2), a turret (10) positioned in the compression section in an operational position, at least one filling device (12) associated with the turret (10). A support assembly (160) is provided to support a feeder (15) of a filling device (12) of the rotary tablet press (1), the support assembly being configured such that the view to the second portion and across the gap is substantially unimpeded.
