Among the figure: 1, support, 2-1, active profile of tooth belt wheel, 2-2, driven toothed belt wheel, 3, cog belt, 4, the light lotus root, 5, leading screw, 6, screw, 7, the guiding jacket casing, 8, flange, 9, manometric head, 10, medicine plate, 11, pressure transducer, 12, sensor stand, 13, tablet, 14, light barrier, 15, motor.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of tablet hardness instrument comprises support 1, active profile of tooth belt wheel 2-1, driven toothed belt wheel 2-2, cog belt 3, light lotus root 4, leading screw 5, screw 6, guiding jacket casing 7, flange 8, manometric head 9, a medicine plate 10, pressure transducer 11, sensor stand 12, light barrier 14, motor 15.Motor 15, leading screw 5, guiding jacket casing 7 and light lotus root 4 are installed on support 1.Initiatively profile of tooth belt wheel 2-1 is connected on the axle of motor 15, and driven toothed belt wheel 2-2 is connected on the leading screw 5, and initiatively profile of tooth belt wheel 2-1 is connected by cog belt 3 with driven toothed belt wheel 2-2.Guiding jacket casing 7 one ends are connected with support 1, and the other end is connected with flange 8, and screw 6 is slidingly mounted in the guiding jacket casing 7, is connected on the leading screw 5.Light barrier 14 and manometric head 9 are connected on the screw 6.Propping up medicine plate 10 is connected on the manometric head 9.Sensor stand 12 is fixed on the flange 8.Pressure transducer 11 is fixed on the sensor stand 12.Motor 15 drives leading screw 5 rotations by synchronous belt drive mechanism, thereby being installed in screw 6 on the leading screw 5 changes rotatablely moving of leading screw 5 into rectilinear motion and drives manometric head 9 and do rectilinear motion toward the direction of pressure transducers 11, the tablet 13 that is put between manometric head 9 and the pressure transducer 11 is delivered to the power of the extruding of suffered manometric head 9 on the pressure transducer 11 of opposite side, pressure transducer 11 output pressure signals are to control system, when tablet is cracked, control system control motor 15 cuts out, thereby and the control display device show that the tablet hardness number obtains the hardness of tablet.
Principle of work of the present utility model:
Put a tablet 13 on a medicine plate 10, during the work of tablet hardness instrument, motor 15 drives leading screw 5 rotations by synchronous belt drive mechanism, and the screw 6 that is installed on the leading screw 5 changes rotatablely moving of leading screw 5 into rectilinear motion.The light barrier 14 that this moment, screw 6 drives were connected on the screw 6 moves toward light lotus root 4 places, shelters from light lotus root 4 until light barrier 14, and motor 15 stops.Motor 15 beginnings motion in the other direction then, promptly screw 6 drives the direction motion toward pressure transducer 11 of manometric head 9, a medicine plate 10 and tablet 13.When tablet 13 was run into pressure transducer 11 by the time, manometric head 9 began to push tablet 13 until cracked, motor 15 stop motions.Motor 15 motion in the other direction then, be that motor 15 drives leading screw 5 rotations by synchronous belt drive mechanism, thereby drive screw 6, manometric head 9, a medicine plate 10 and light barrier 14, shelter from light lotus root 4 until light barrier 14 toward the motion of light lotus root 4 places, one-time detection is finished in motor 15 stop motions.
