摘要:
Bei einem Verfahren zum Kristallisieren von zum Verkleben neigenden Kunststoffgranulaten, insbesondere PET- und PU-Granulaten, wird das Granulat im Bereich seiner Reaktionstemperatur in einer Vibrationsrinne (1) einer Schwingungserregung quer zur Längserstreckungsrichtung der Rinne unterworfen. Der Granulatstrom bewegt sich auf einer schraubenförmigen Bahn durch die Rinne. Hierdurch wird ein enges Verweilzeitspektrum sowie ein homogenes Temperaturprofil für die Granulatteilchen erzielt. Zudem wird ein Verkleben derselben zuverlässig unterbunden.
摘要:
In order to provide the capability of distributing a material that is conveyed, a vibratory distribution conveyor (10) includes a deck (12) having a distribution edge (16). The distribution edge extends between an inlet end (14) and an end (18) remote therefrom and the deck (12) is subject to vibratory motion to cause material to be conveyed from the inlet end (14) toward the end (18) remote therefrom. With this arrangement, the declination of the deck is controlled about the longitudinal axis (20) to control the distribution characteristics of the conveyor (10).
摘要:
A balanced vibration generator (1) for resonance-amplified operation of a machine or equipment (20) comprises at least one set of counter-oscillating masses (4, 16, 20) suspended in a spring system (3) in which the resonance springs are helical springs which also support the masses. The generator comprises a built-in, balanced drive system (6, 7, 8). The generator is suspended in securing elements (10, 11) which comprise special, adjustable securing elements (9) which are in engagement with the resonance springs (3) and arranged in such a manner that the resonance springs, when turned around their longitudinal axes (14), can change spring lengths.
摘要:
A loose material conveyor is given a high degree of freedom in the horizontal and vertical plane of oscillation by the horizontal arrangement of rod spring components (1). The oscillating conveyor is automatically taken into the best possible working range by monitoring the phase relation of the mechanical and electrical oscillation circuit by means of a sensor (60). The speed can be steplessly controlled by the amplitude reference setting (42). Owing to its high conveying dynamics, the conveyor is ideal for the volumetric metering of loose material in the foodstuffs, plastics, building, chemical and pharmaceutical industries. Another application is in the preparation of SMD components for an automatic SMD system.
摘要:
Vibratory material handling equipment suspension systems. The problem with conventional vibrating devices for driving work members is that they lack adjustability and are very complex. The solution is to design a torsional vibrating device (10) for operation as a two mass vibrating system consisting of a first mass having a generally circular work member (22) and a spring mechanism (12) connecting the first mass to the second mass (27) excited by a motor driven eccentric weight or weights (14) so that the second mass (27) vibrates in a circular path having a circular component and a vertical component which will cause material on said work member (22) to be conveyed in a circular direction. The spring member (12) is unique in this combination. The entire system is isolated from a support structure (20). This system has application for controlling the flow of bulk material from a hopper (16), screen (123) or feeder (222) or for elevating or lowering a material in a helical trough (323) or for orientation of discrete particles (322) or other applications depending on a properly designed work member.
