Research on a Quantitative Packing Weighing System of Sticky Foods
Applied Mechanics and Materials(2013)
Abstract
According to the problems of slow weighing speed and low precision resulting from sticky foods caking in quantitative packing weighting, the mechanical structure, the circuit system and the software algorithm were designed in this paper. To improve the weighing speed and precision of sticky foods, the double-tube spiral feeding machine and a special structure of scale bucket were adopted in mechanical structure; a programmable AD8555 was used as weak signal amplifier of weighing sensor and a 32-bit microprocessor LP2134 was utilized as the core of the circuit system; the piecewise weighing method, FIR software filter and the differential algorithm are applied to send command to executive mechanism in program design.
