Abstract

The invention discloses a tobacco leaf boxing density deviation pressure detection method and a detection device thereof and relates to a pressure detection device and the detection method thereof. The detection device is provided with at least one data acquisition device and a data processing system, and the data acquisition device is connected with the data processing system; the data acquisition device is provided with a press head, a sampling device, a pressure sensor and a data acquisition card, the sampling device is fixed on the pressure sensor, the sampling device is embedded in the press head, the end surface of the sampling device is higher than the press head, the pressure sensor is connected with the data acquisition card, the pressure sensor and the data acquisition card are fixed on the upper surface of the press head, an input port of the data processing system is connected with the electric signal output end of the data acquisition card. The testing method comprises the following steps: sending a tobacco leaf box which is full of tobacco leaves to the position below the press head; pressing the press head downwards and stopping pressing the press head till the height of the tobacco leaves is 650-00mm; reading electric signals of the sensor, transmitting the electric signals to an industrial personal computer and obtaining the boxing density through calculating;and raising the press head to complete the detection. The cost can be reduced, the personal safety can be protected and multiple choices can be provided for an enterprise.

Description

Technical field [0001] The invention relates to a pressure detection device and a detection method thereof, in particular to a pressure detection method and a detection device for the packing density deviation of tobacco leaves in threshing and redrying. Background technique [0002] Packing and packing of tobacco leaves is the last process of the threshing and redrying production line. If the packing density deviation of tobacco leaves is too large, the tobacco leaves in the tobacco box will not be uniform, which will not only cause the moisture, temperature and pressure of the tobacco leaves in the box to be unbalanced, but also store the tobacco leaves. Storage and fermentation bring adverse effects, such as easy agglomeration, oil production, charcoal burning, etc., which are directly related to the stability of tobacco leaf quality; and it also brings inconvenience to the subsequent silk making process, such as loose chips in silk making It is easy to cause the leaves to be ...
