Loading tracking apparatus

Abstract

A loading tracking apparatus comprises a loading spraying needle frame, an upper swing arm, a lower swing arm, an upper-swing-arm driving member, a lower-swing-arm driving member and a swing-arm installation support; the loading spraying needle frame is arranged at a working end of the upper swing arm and is hinged to the upper swing arm; the upper swing arm and the lower swing arm are in hinged connection; the swing-arm installation support is hinged to the lower swing arm; the lower-swing-arm driving member drives the lower swing arm to swing via a lower-swing-arm parallelogram link mechanism, and the upper-swing-arm driving member drives the upper swing arm to swing via an upper-swing-arm parallelogram link mechanism; the loading spraying needle frame keeps translational movement during swinging of the swinging arms via a translational-movement parallelogram link mechanism; and the lower-swing-arm parallelogram link mechanism, the upper-swing-arm parallelogram link mechanism and the translational-movement parallelogram link mechanism all employ the central part of a pair of self edges as a rotation hinge joint. The provided loading tracking apparatus guarantees the loading spraying needle frame to steadily operate without shaking and always keep translational movement.

Description

technical field [0001] The invention mainly relates to the field of food and medicine packaging machinery, in particular to a filling tracking device. Background technique [0002] In the field of food and pharmaceutical packaging machinery, the demand for filling speed of filling machines continues to increase, which makes the safety and stability of filling machines need to be improved during operation. In the existing continuous filling technology, the filling tracking generally adopts the slider mechanism (the stability of the filling needle position depends on the machining accuracy of the cam and the quality of the cam curve, and the cam needs to be replaced for different bottles) or the swing arm tracking of the manipulator. structure, the existing manipulator swing arm is generally driven by a transmission belt or a single parallelogram structure, and the transmission jitters greatly when running at high speed, and the operation is unstable.
