Fig. 2 be this measuring head pressure automatic transfer equipment structural representation two
Five, embodiment
Embodiment one: referring to Fig. 1, a kind of measuring head pressure automatic transfer equipment among the figure, contain measuring head 7 and counterweight thereof, and the cam 6 that promotes measuring head 7, the top wheel 10 that cooperates with cam 6 is installed on the described counterweight, described counterweight is a magnet first 5, be provided with the additional bob-weight device on described counterweight top, described additional bob-weight device comprises that the magnet second 4 of lower end, magnet second 4 tops connect support 8, the opposite side of support is connected with tooth bar 2, this tooth bar 2 is driven by servomotor 1, and described magnet first 5 is that magnetic pole of the same name is relative with magnet second 4.
Between described magnet second 4 and the support 8 pressure transducer 3 is installed, pressure transducer 3 is connected with servomotor 1 by cable.Described magnet first 5 and magnet second 4 are permanent magnet.
Connect by column 9 between described measuring head 7 and the magnet first 5; The gross weight of measuring head 7, magnet first 5 and column 9 is 1 kilogram.
When carrying out the measurement of stem filling value, magnet second 4 rises to peak, magnet second 4 and magnet first 5 are same polarities, but because the distance between them is very big, he does not almost have acting force to following magnet first 5, cam 6 drives measuring head 7, column 9 and 5 motions of magnet first that gross weight is 1KG, finishes the measurement of stem filling value.
When carrying out the tobacco fill value measurement, when measuring head 7, column 9 and magnet first 5 descend, servomotor 1 drives magnet second 4 and descends, approaching along with magnet second 4 and magnet first 5, acting force between them is also increasing, pressure transducer 3 in the magnet second 4 feeds back to servomotor 1 to force value, when the acting force between magnet second 4 and the magnet first 5 reaches 19.6N, 4 stop motions of magnet second, measuring head 7, column 9 and magnet first 5 integral body are exactly 9.8N+19.6N=29.4N to the pressure of sample so, just in time are that tobacco fill value is measured needed force value.
