Automatic weighing machineTechnical field
The utility model is related to the weighing-appliance in a kind of active carbon production line, more particularly to a kind of automatic title that can be liftedHeavy-duty machine.
Background technology
In existing process, in the middle of activated carbon modified production process, by activated carbon and liquid modifying agent stirring be mixed it is even after, thenPeople's tool disk is weighed again.Because granular activated carbon low intensity, frangible, and has certain viscosity, so wanting gentle manipulation, one when weighingAs produce in be all soft charging by hand, but this conventional approach has that efficiency is low, and labour intensity is big, it is impossible to continuous prodution.
The content of the invention
The purpose of this utility model is to provide a kind of discharging opening splicing that can automatically rise to upstream equipment, fills after expecting certainlyDynamic lower general who has surrendered's loading tray is positioned over the automatic weighing machine on conveyer belt, operates steadily, weighs accurately.
The utility model proposes including frame, lift cylinder, weighing unit, lifting weighting platform, frame is provided with installation base plate, determinesPosition substrate, the cylinder barrel of lift cylinder is fixed on installation base plate or positioning substrate, and its piston rod passes through positioning substrate and weighing unitIt is fixedly connected, weighing sensor is installed with weighing unit, equipped with lifting weighting platform on weighing sensor；By the letter of weighing sensorNumber control the action of its lift cylinder.
Preferably, equipped with multiple guide rod devices on the installation base plate, guide rod device includes guide rod cylinder and guide rod, guide rod cylinderIt is fixed on installation base plate, guide rod is fixedly connected through positioning substrate with weighing unit..
The installation base plate is made up of support and guide rod supports plate.
The guide rod cylinder is fixed on guide rod supports plate；The cylinder barrel of the lift cylinder is fixed on positioning substrate, cylinder barrelSupporting plate is reinforced with cylinder is provided with positioning substrate connection.
Weighing sensor sets specified weighing value, when weighing sensor receives photosignal or senses on lifting weighting platformDuring empty loading tray, lift cylinder is issued instructions to, the piston rod of lift cylinder stretches out, drive lifting weighting platform to rise to setting positionSplicing, when the loading tray that weighing sensor is sensed on lifting weighting platform feeds to setting weight, issues instructions to lift cylinder,The piston rod of lift cylinder withdraws, and drives lifting weighting platform to decline and resets.
The beneficial effects of the utility model are：The discharging opening splicing of upstream equipment can be automatically risen to, is filled automatic after expectingLower general who has surrendered's loading tray is positioned on conveyer belt, is operated steadily, is weighed accurate, realization automation continuous weighting.Guide rod device risesTo support and the effect being oriented to so that weighing unit and lifting weighting platform operate steadily up and down, possess weight capacity.The guide rod cylinder is solidIt is scheduled on guide rod supports plate；The cylinder barrel of the lift cylinder is fixed on positioning substrate, and guide rod cylinder, cylinder barrel are separately fixed at two-phaseTo substrate on, be conducive to equilibrium stress, make weighing unit and lifting weighting platform operation more steady, extension device service life.
When weighing sensor is when empty pan weight is sensed, weighing sensor sends signal, and lift cylinder holds up loading trayLeave into disk conveyer belt to the discharging opening near upstream equipment, when the material of loading tray reaches the weight of setting, weighing and sensingDevice sends signal, and discharging opening is closed, and lift cylinder drives loading tray to decline reset, dishful is gently placed on centre and is provided with titleOn the conveyer belt of weight open slot, lifting weighting platform may pass through open slot of weighing and hold up or place loading tray.

Specific embodiment
Embodiment one
Reference picture 1, the present embodiment includes frame 1, lift cylinder 2, weighing unit 3, lifting weighting platform 4, and frame is provided with installationSubstrate 5, positioning substrate 6, the cylinder barrel of lift cylinder are fixed on positioning substrate 6, and its piston rod 7 passes through positioning substrate 6 and weighsPlatform 3 is fixedly connected, and weighing sensor 8 is installed with weighing unit 3, equipped with lifting weighting platform 4 on weighing sensor 8；By biography of weighingThe signal of sensor 8 controls the action of lift cylinder 2.Equipped with multiple guide rod devices 9 on the installation base plate 6, guide rod device 9 includesGuide rod cylinder and guide rod 10, guide rod 10 are fixedly connected through positioning substrate 6 with weighing unit 3.The installation base plate 6 is by support 11 and leadsBar supporting plate 12 is constituted.The guide rod cylinder is fixed on guide rod supports plate 12；The cylinder barrel of the lift cylinder 2 and positioning substrate 6Junction is provided with cylinder and reinforces supporting plate 13.
Weighing sensor 8 sets specified weighing value, when weighing sensor 8 receives photosignal or senses on lifting weighting platformEmpty loading tray when, issue instructions to lift cylinder, the piston rod of lift cylinder stretches out, drive lifting weighting platform rise to setting positionSplicing is put, when the loading tray that weighing sensor is sensed on lifting weighting platform feeds to setting weight, lifting air is issued instructions toCylinder, the piston rod of lift cylinder withdraws, and drives lifting weighting platform to decline and resets.
Preferred embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited,The equivalent structure transformation that every utilization the utility model specification and accompanying drawing content are made, or directly or indirectly it is used in correlationTechnical field, is included in scope of patent protection of the present utility model.
