Filter stick forming machine filter stick weighing device and weight detection signal separating method

Abstract

The invention relates to a filter stick forming machine filter stick weighing device and a weight detection signal separating method. The filter stick forming machine filter stick weighing device comprises a guiding module and a weighing module which are arranged up and down, the guiding module comprises a hopper, a feeding channel and a removing port from top to bottom in sequence, and a fixing shelf capable of making filter sticks flushed with one another left and right and linearly distributed is further arranged in the hopper; the weighing module comprises a shell, a discharging channel and a weighing balance, the discharging channel and the weighing balance are arranged in the shell, the discharging channel is connected with the feeding channel, and the weighing balance is located atthe lower portion of the discharging channel, and further electrically connected with a converter arranged at one side. The filter stick weighing device has the advantages of being high in sensitivity, accurate in measuring, stable in data transmission, convenient to operate and the like; by means of the method, a signal analysis model and a signal conversion model are provided, and the method hasthe advantages that the signal detection capability is strong, the local signal separating identification degree is high, and the signal acquisition and utilization range is wide.

Description

technical field [0001] The invention relates to the relevant technical field of a filter rod forming machine, in particular to a filter rod weighing device of a filter rod forming machine and a method for separating weight detection signals. Background technique [0002] The filter rod forming machine is mainly used to produce filter rods. Its built-in quality inspection device can detect the abnormal information of the filter rods, but some abnormal information cannot be directly identified and utilized, resulting in the failure to remove filter rods with excessive weight, for example, causing quality problems. For this reason, how to separate the filter rod detection signal and apply it to the rejection of filter rods with excessive weight is a difficult problem in the study of the stability of the filter rod forming process. Referring to other signal separation methods, there are many methods proposed for this. [0003] For example: Shandong University (Liu Ju, Mei Liangm...

AI Technical Summary

Problems solved by technology

Since all signals are packaged and transmitted, they are blind source signals, so the source signal of the self-test signal cannot be accurately known and best estimated, resulting in signals that cannot be directly identified and used later
