Summary of the invention
The object of the invention is the deficiency existed for prior art, provide a kind of rational in infrastructure, degree of automation is high, the jumbo bag compress that often bag jumbo bag packing materials weight is consistent.
For achieving the above object, the technical scheme that jumbo bag compress of the present invention adopts is:
A kind of jumbo bag compress, comprise top and valvular feeding cylinder is installed, the lower end of feeding cylinder is connected with tremie pipe by flexible pipe, and the bottom of tremie pipe is provided with discharging opening, and feed pipe is provided with level-sensing device, tremie pipe is provided with bag-clamping mechanism, feeding cylinder is provided with retractor device, and one end of retractor device is connected with feeding cylinder, and the other end is connected with tremie pipe, described valve is connected with PLC with level-sensing device, and the control setup of retractor device is connected with PLC.Flexible pipe adopts spring hose, and intensity is higher.Jumbo bag is added the discharge port end being held in tremie pipe by bag-clamping mechanism, material enters jumbo bag by valve by feeding cylinder, flexible pipe and tremie pipe, jumbo bag is constantly full of by material, time on material completely to level-sensing device position, PLC receives the electric signal of level-sensing device, valve-off, by control setup, retractor device is upwards contracted, level-sensing device falls into jumbo bag to the material in discharging opening, and packing terminates, and ensures that in each jumbo bag of packing, weight of material is consistent.
Described feeding cylinder is provided with the blast pipe be communicated with it.The blower fan that blast pipe connects or air intake valve are connected with PLC.Before convey materials, blast pipe can be inflated to jumbo bag, jumbo bag is thoroughly opened, is convenient to charge material.
Described blast pipe is provided with the branch road be communicated with it, and this branch road is provided with shutoff valve.Shutoff valve is connected with PLC.When shutoff valve is closed, air inlet pipe air inlet makes jumbo bag open to jumbo bag inflation, and when filling material, air inlet pipe stops air inlet, and shutoff valve is opened, and for exhaust, makes material can enter jumbo bag smoothly.
Described valve is gate, and gate locating has the first cylinder, and the control cock of the first cylinder is connected with PLC.Gate can improve the speed of charging as the valve of charging, convenient operation.
The direction that described gate is opened is acute angle with angular separation straight up.Gate is arranged obliquely, meets the gravity of material and the rule of path of motion, reduces the resistance opening and closing gate.
Described gate opening direction is 45-65 degree with angular separation straight up.Optimum angle is 60 degree, and the resistance opening and closing gate is minimum.
Between gate and feeding cylinder, be provided with feeder hopper, feeder hopper is up big and down small, and feeding cylinder is connected with small end, and gate locating is in feeder hopper upper end.Up big and down small feeder hopper can buffer memory material, and ensure can be full of material when material reaches level-sensing device height below level-sensing device, these materials are all filled in jumbo bag under the effect of retractor device, ensure that the weight of material in each jumbo bag is consistent.
Described retractor device is the second cylinder, and the control cock of the second cylinder is connected with PLC.Cylinder is relatively cleaner and tidier, is applicable to Fodder and food industry and uses.Tremie pipe is pulled upwardly by the second cylinder, and hose contracts is all filling in jumbo bag by the material below level-sensing device.
Described bag-clamping mechanism comprises the sackholder hinged with tremie pipe and drives the 3rd cylinder of sackholder, described sackholder comprises the clip that two splits are split, two clips are encircled at tremie pipe outside, clip is connected with rocking arm; rocking arm and tremie pipe hinged; the 3rd cylinder one end and the hinged other end of clip and tremie pipe hinged, the control cock of the 3rd cylinder is connected with PLC.3rd Telescopic-cylinder drives clip close or open, and clip closes discharge port end jumbo bag being clamped in tremie pipe, improves the speed of filling material.
The two ends of described clip are provided with elastic cushion block.Elastic cushion block has cushioned impulsive force when clip closes, and improves the service life of clip, also reduces operation noise simultaneously.
The present invention compared with prior art, has the following advantages:
Jumbo bag is clamped in discharge port end by bag-clamping mechanism, material enters feeding cylinder from valve, jumbo bag is entered through flexible pipe and tremie pipe, jumbo bag is filled up by material, material constantly docks in tremie pipe and flexible pipe, when material reaches level-sensing device position, PLC receives the electric signal of level-sensing device, valve-off stops charging, retractor device shrinks upwards mentions tremie pipe, hose contracts, under the suction double action of gravity and material slippage, material below level-sensing device is all filled in jumbo bag, bag-clamping mechanism is opened, packing terminates, weight of material in jumbo bag is consistent, achieve the packing of automatic jumbo bag, response time is fast, improve packing efficiency.The present invention, relative to the jumbo bag compress of prior art, saves weighting apparatus, relatively simple for structure, and reduces cost.
Detailed description of the invention
