It can be appreciated that the formula of the resistance value of the resistor and the length of the material is:
R＝ρ.L/S，
where ρ is a proportionality constant, ρ is related to the material of the conductor, and is a physical quantity reflecting the conductive properties of the material, called the resistivity of the material. R is the resistance of the resistor, L is the length, and S is the cross-sectional area.
As can be seen from the formula, the resistance of the resistor is proportional to the length of the conductor and inversely proportional to the cross-sectional area, i.e. the greater the length L, the greater the resistance R of the resistor. When foam material in the storage bin gradually descends along with foam discharge at the bottom, the floats 501 can synchronously descend along with the foam material in the direction of the supporting columns 3, namely, the floats 501 move towards the direction of the chassis 4, the guide wheels 504 connected with the floats 501 synchronously descend, contacts 302 are arranged in the directions of different lengths of the outer sides of the supporting columns 3, the guide wheels 504 are respectively contacted with the contacts 302 of the outer sides of the supporting columns 3 to form a passage, and the length L of the passage is larger as the guide wheels 504 are far away from the top plate 1, so that the resistance R of the resistor is larger, and the current is smaller.
The relationship between current and resistance is formulated as:
I＝U/R，
in the formula, I is current, U is voltage, R is resistance, and the formula shows that the resistance R is inversely proportional to the current I, and the larger the resistance R is, the smaller the current I is.
The invention also discloses a detection method of the EPS foam bin, and the detection method is applied to the detection device of the EPS foam bin.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
