First open the feed bin lid 1-1 of described feed bin 1, put into the required material added, then cover feed bin lid 1-1.
Afterwards, open this pulvis trace and add gauge source switch, gauge starts, now arrange gauge according to above-mentioned parameter, after being provided with, gauge starts to feed intake according to quantitative model, in the process fed intake, the red LED lantern festival in control setup is always bright.This pulvis trace interpolation gauge starts first to control described mixing device 8 by described control setup and starts, described mixing device 8, comprise two mixers, i.e. the first mixer 8-1 and the second mixer 8-2, two turning cylinders, i.e. the first turning cylinder 8-3 and the second turning cylinder 8-4, and driver train, wherein: described driver train is made up of two sprocket wheels, i.e. the first sprocket wheel 8-5 and the second sprocket wheel 8-6, chain 8-7 and the second variable-frequency motor 8-8; Described second variable-frequency motor 8-8 is coordinated by described two sprocket wheels and described chain 8-7's, drives described two turning cylinders to rotate, and then drives the rotation of described two mixers.Like this, be rotated through two sprocket wheels by the second variable-frequency motor 8-8 and drive two mixers to rotate to overturn material with the transmission that coordinates of chain 8-7, to prevent material from tying arch, and then ensure the discharging of material stable and uniform.
While described mixing device 8 startup, the described control setup described thick gauging device 6 that can control in described charging device starts to start; For realizing completing feeding intake of 800g within the time of 80s, now, first variable-frequency motor 6-1 of described thick gauging device runs according to the kinematic velocity set, material is extruded, feed intake, when the numerical value of thrown material reaches 800g, described LOAD CELLS 4 sends the governor circuit of signal to described control setup, after receiving this signal, and then controlled to stop the first variable-frequency motor 6-1 of described thick gauging device 6 out of service by described control setup.
After described thick gauging device is out of service, described control setup controls described smart gauging device 7 to start to start, wherein, the speed that the stepping motor 7-1 of described smart gauging device 7 starts to set is run, guarantee that in 40s, remaining 200g material being extruded feed bin feeds intake, until when its weight reaches 200g, described LOAD CELLS 4 sends the governor circuit of signal to described control setup, after receiving this signal, now to control described stepping motor 7-1 out of service for described control setup, and the red LED lamp in control setup is extinguished.
In the above process, thick gauging device 6 adopts frequency conversion system, the step-servo system that smart gauging device 7 adopts higher reaction sensitiveer, and then can ensure that realizing accurate stable continuous measurement adds materials.
Feed intake complete after, described control setup will described mixing device out of service, namely complete the process that once feeds intake, if having selected automatic mode, gauge can enter next Automatic feed cyclic process automatically, and pattern is still quantitatively add; If have selected manual mode, after gauge completes and this time feeds intake, gauge will stop motion, can not automatic cycle.
When the expected value of adding total amount is less than or equal to 500g, the governor circuit of gauge can automatically be given tacit consent to the expected value of adding total amount and all be completed by described smart gauging device 7, namely along with while described mixing device 8 startup, the described control setup described smart gauging device 7 that can control in described charging device starts to start, then governor circuit can according to the target weight value of setting, allow the running velocity of the stepping motor 7 of time and the setting fed intake, then, stepping motor 7 can run with this speed, ensure that the weight of throwing in material within the time allowing to feed intake reaches target weight value.
Embodiment two (constant speed mode):
In the production process of reality, sometimes need, for manufacturing line adds materials with stable speed continuously, now just can select constant speed mode, namely can add corresponding material by constant speed at this rate by gauge after presetting motor speed.In using, operator is constant speed mode by the first touch button setting operational mode, selects automatic mode or manual mode; The target weight value of setting; Select charging device, namely select thick gauging device to feed intake or select smart gauging device to feed intake; The charging device of setting, namely thick gauging device feeds intake or the corresponding motor rotating speed of smart gauging device; The permission charging time of setting.
When first opening the feed bin lid 1-1 of described feed bin 1, putting into the required material added, then covering feed bin lid 1-1.
Afterwards, open this pulvis trace and add gauge source switch, gauge starts, now arrange gauge according to above-mentioned parameter, after being provided with, gauge starts to feed intake according to quantitative model, in the process fed intake, the red LED lantern festival in control setup is always bright.This pulvis trace interpolation gauge starts first to control described mixing device 8 by described control setup and starts, like this, being rotated through two sprocket wheels by the second variable-frequency motor 8-8 drives two mixers to rotate to overturn material with the transmission that coordinates of chain 8-7, to prevent material from tying arch, and then ensure the discharging of material stable and uniform.
If operator utilizes the charging device of selection to be thick gauging device, namely the kinematic velocity of the first variable-frequency motor 6-1 of described thick gauging device 6 is set, the charging time of target weight value and permission, while starting along with described mixing device 8, the described control setup described thick gauging device 6 that can control in described charging device starts to start, then continual the stablizing of speed set according to operator feeds intake, to having produced, and the stop motion of described thick gauging device 6; If have selected automatic mode, gauge can enter next Automatic feed cyclic process automatically, and pattern is still for constant speed is added; If have selected manual mode, after gauge completes and this time feeds intake, gauge will stop motion, can not automatic cycle.
If operator utilizes the charging device of selection to be thick gauging device, namely the kinematic velocity of the first variable-frequency motor 7-1 of described smart gauging device 7 is set, the charging time of target weight value and permission, while starting along with described mixing device 8, the described control setup described smart gauging device 7 that can control in described charging device starts to start, then continual the stablizing of speed set according to operator feeds intake, to having produced.Red LED lantern festival in control setup is extinguished, the stop motion of described smart gauging device 7; If have selected automatic mode, gauge can enter next Automatic feed cyclic process automatically, and pattern is still for constant speed is added; If have selected manual mode, after gauge completes and this time feeds intake, gauge will stop motion, can not automatic cycle.
