Abstract
The utility model discloses a weighing control system by micro-computer for powder continuous package. A feeding mechanism of the utility model is provided with a metallic perforated tube 6 and a perforated tube box 7, and the feeding mechanism transmits materials to a discharge opening by air. A rubber valve structural member 3 made of rubber and metallic materials is deformed to seal the discharge opening under the condition of air pressure, and which controls the materials to spray in a packaging bag. A microcomputer 1 collects weight information of a packaging bag by a sensor 4, and controls the operation of the rubber valve structural member 3 by an electromagnetic valve 5; thereby, the operation of automatical metering, definite quantity packing, display and printing can be realized. The utility model has the advantages of high packing precision and high metering precision (when users pack one bag with 50 kg, and the error is less than 1 kg), the qualified rate of continuous packing reaches to 95 per cent, and the cost is low.
Description
The utility model relates to a kind of package metro-measuring control setup, and this device is used for specially to the continuous package metro-measuring control of powder material, for example, and cement packing measure control etc.
Present cement packing metering control adopts mechanical type lever to claim principle more.Most typical mechanical type lever claims the package metro-measuring device to form and work is such: choose a position by a certain percentage and make supporting-point on lever, an end of lever is hung weight, the material metering of the other end to packing with pocket.When powder material (as cement) enters weight in the pocket when reaching specified quantity (for example 50 kilograms), lever falls automatically.A kind of instrument of slotting tool that cries automatically shuts down discharging opening, and weight moves up automatically, and the pocket that manually will install cement is taken off, and has finished the task of one bag of package metro-measuring.But Packing Unit is big during owing to production cement, what have reaches per hour 50 tons, want one bag of cement of package metro-measuring average per 10 seconds, speed is exceedingly fast, add that mechanical action is extremely frequent, the edge of a knife wearing and tearing at the supporting-point place also are exceedingly fast, and cause the mechanical lever ratio to change, bench mark (zero point) drift, thereby measure inaccurate.It is inhomogeneous to add the interior cement supplied materials of cement bin, often piles up the cement dust on weight and each mechanical fastener, has a strong impact on accurate measure control.Simultaneously, slotting tool is also often blocked by particle in the cement, claims that body is malfunctioning, can't work.Often be by workman's experience range estimation metering, hand-filling in most producers reality.Qualification rate has only 50-70% as a result.What have undergoes technological transformation to this, for example adopts transistor type electric-examination method, and integrated circuit control and non-contact type are controlled near on-off mode, and the employing system controlled by computer mode that also has is carried out metering packing.But these package metro-measuring control system still adopt the lever scale principle, and all the aforementioned mechanical type lever of pendulum holder does not claim mode.Such as generally all being above the weight that former machinery claims, to add sensor or near switch etc., therefore still exist aforementioned mechanical type lever to claim the shortcoming of body.Its control system can not solve the zero creep phenomenon, must often will manually participate in levelling, so stability is poor, is not suitable for requirement of mass production.
Task of the present utility model is to overcome inaccurate or the defective that can not stable operation of powder material package metro-measuring in the past, make a kind of high precision, high qualification rate (reaching more than 95%), good stability, cost is low, can satisfy the continuous package metro-measuring control setup of powder material of producing needs continuously in enormous quantities.
