摘要:
An apparatus and method for determining the force-displacement diagram of pairs of punches in a rotary pelleting machine involving measuring and storing the course of compression of punch pairs for each individual angle step, storing said data and preparing a correction table in a computer which is compared to the theoretical values of displacement.

A sealing strip for a housing of a pelletizing machine has a one-piece sealing body with a central web with an upper side having two upper edges and a lower side having two lower edges, two sealing lips extending from the upper edges of the upper side of the central web at an angle relative to one another, and a clamping strip extending from a center of the lower side of the central web and provided with lateral webs.
摘要:
A rotary compression press for cylindrical compacts, especially tablets, comprising a rotatably driven rotor including a die-plate and an upper and a lower ram guide for upper and lower rams cooperating with the die bores, and a pressure station with an upper and a lower pressure roller for applying a pressing power to the rams wherein the rams circumferentially have an annular tooth system which cooperates with an opposed tooth system in the area of a pressure station for the rams for the purpose of rotating the rams in the die bores thereof, characterized in that the opposed tooth system is defined by a rotatably supported gear which is acted on by a preset braking torque with the braking torque being chosen so as to be smaller than the torque of the ram when under a maximum pressing power.
摘要:
A method for adjusting a stamp relative to a matrix on sinter-pressing, characterized by the following method steps: the stamp and the matrix are so moved towards one another that the stamp is located in a position shortly before the immersing into the bore of the matrix; the region of the stamp is illuminated; on the side distant to the stamp there is positioned an optical recorder which acquires the matrix bore; the picture recorded by the recorder is imaged on a monitor; in accordance with the imaging on the monitor the stamp relative to the matrix is so adjusted transversely to its axis that a uniform gap between the stamp and the matrix bore over the circumference is obtained; and subsequently the stamp is finally fixed in its receiver.
摘要:
A method of depositing dosed quantities of pulverized lubricants or parting compounds on the materials contacting surfaces of pressing tools of tabletting machines, according to which the parting compound uniformly distributed by a gaseous transport medium is blown on the surfaces, said parting compound during operation of said tabletting machine being continuously blown on the used surfaces and being removed from the areas adjacent to the used surfaces by suction continuously.
摘要:
An operating stand for a tablet press device which comprises a process computer with a screen and an input keyboard and where appropriate a printer, wherein the operating lectern is mounted height-adjustable on a traversable base and between the base and the operating lectern there is arranged a linear adjusting drive with a linear guide.
摘要:
A rotary pelletizing machine has a rotatable matrix disc, a plurality of vertically adjustable pressing rollers which control position of the upper and lower plungers, a drive for a height adjustment of the rollers, a housing accommodating the drive, and a bearing block supporting the pressing roller and releasably connected with the housing.
摘要:
A rotary pelletizing machine comprises a rotatable matrix disc, a plurality of upper plungers and lower plungers guided in the matrix disc, and an element for holding the lower plungers from falling out during a dismounting of the matrix disc, the holding element including a braking ring arranged in the matrix disc and pressing radially against the lower plungers so as to hold the lower plungers from falling out.
摘要:
A die for a rotary compression press, comprising a die holder axially supported in a guide bore and a die insert which is seated in the end-side bore of the die holder via a trunnion-shaped projection and is adapted to be mounted via releasable fastening means, wherein the projection is helically guided in the bore between axially spaced stops and is biased by a spring towards the associated front-end face of the die holder.
摘要:
A rotary tablet press, with a die plate rotatably mounted in a housing, which comprises guides for the upper and lower punch, whose position is controlled by cam disks rigid with the housing, and with an upright drive shaft which is arranged below the die plate and which can be releasably coupled to the die plate, wherein the die plate is formed such that after releasing from the drive shaft and a slight raising it may be moved out laterally, wherein at the ends, facing one another, of the die plate and drive shaft there is provided a quick locking whose parts are arranged in cavities of the die plate and drive shaft and which may be actuated by an actuation rod which is movably mounted in an axial channel of the drive shaft and is actuatable by an actuation device for the selective tensioning or releasing of the die plate and drive shaft.
