Description
Technical field
The present invention relates to a kind of stack temperature compensation means for plastic sheeting process equipment.
Background technology
Plastic sheeting process equipment is by the extrusion equipment of plastic sheeting, rolling equipment and taking-up equipment composition, extrusion equipment is extruded after being heated by plastic raw materials, the plastic raw materials extruded is transported to rolling equipment and rolls, form film, rolling equipment comprises multipair stack, progressively that film is ironed by multistage calendering, finally form required thickness, plastic sheeting the most up to standard is transported to taking-up equipment and carries out coiling into tubular, in calender line, cool to prevent plastic sheeting and cannot roll, stack is communicated with high temperature circulation conduction oil, because the rotating shaft of stack can continuous distribute heat, therefore, the temperature at stack two ends is lower than middle, under the effect of expanding with heat and contract with cold, distance between two stacks is uneven, gap near stack two ends can be larger, thus the two ends of plastic sheeting are thicker after causing calendering, in prior art, except plastic sheeting both sides are irregular need cutting except, also because the thicker part in the two ends of plastic sheeting need many cuttings some, obtain the plastic sheeting compared with uniform thickness, obviously, cropped fall part, have very large waste, in addition, for the plastic sheeting that thickness required precision is high, for above-mentioned reasons, existing equipment cannot meet.
Summary of the invention
The present invention is according to above deficiency, provide a kind of stack temperature compensation means for plastic sheeting process equipment, utilize this device, hot gas can be blown to stack two ends, carry out temperature-compensating, thus the gap between two stacks can be made to keep uniformity.
Technical scheme of the present invention is:
A kind of stack temperature compensation means for plastic sheeting process equipment, comprise plastic sheeting process equipment, this plastic sheeting process equipment is made up of the extrusion equipment of plastic sheeting, rolling equipment and taking-up equipment, and rolling equipment comprises multipair stack, and stack is communicated with high temperature circulation conduction oil;
It is characterized in that, also comprise:
Frame;
Slide rail, it is fixed in frame, is parallel to the roll shaft of the stack of plastic sheeting output;
Slide block, only can move along slide rail; Slide rail and slide block can coordinate with oat tail groove structure;
Motor, fixes with frame;
Crank, the rotating shaft of its one end and motor is fixed;
Connecting rod, the other end of its one end and crank is hinged, its other end and slide block hinged;
Valve sets, is provided with two groups, and each valve sets is made up of several valves, valve installation is on slide block, two valve sets are respectively near the periphery of stack two end faces, and the nozzle on valve is towards the periphery of stack, and all valves are communicated with High Temperature Gas body source through tracheae, flexible pipe;
Electric machine rotation, moves through crank and connecting rod band movable slider, and the periphery particles of nozzle to stack on final drive two groups of valves blows hot gas.
Existing stack affects by rotating shaft heat radiation, and the temperature of the periphery of close rotating shaft and end face is lower, in order to improve the temperature of this periphery, needs an additional hot gas source to compensate.It is in order to homogeneous heating that the periphery particles of nozzle to stack blows hot gas.
Further, described valve sets has two valves at least, and the hot gas flow near the valve of described stack end face is greater than the hot gas flow of the valve installed near stack center.When there being multiple valve, can arrange by staged temperature, due to stack surface is metal, and finally, under the effect of metal heat conduction, staged temperature can become the temperature close to oblique line.
As preferably, several valves described are uniform, and uniform spacing distance equals the distance that described slide block moves around.
In order to can to enforcement of heating, automatic control, described valve is electric control valve, also comprise controller, multiple temperature sensor, touch-screen display, the quantity of multiple temperature sensor and valve matches, the information of controller collecting temperature sensor, and control signal is transferred to electric control valve, controller is connected with touch-screen display, and multiple temperature sensor is arranged on the periphery of the described stack corresponding with valve.I.e. each electric control valve position of stack of heating, all collect temperature by temperature sensor, the heat that can be obtained electric control valve by controller is exported, such as when temperature sensor gather temperature on the low side time, controller output signal, electric control valve intensifying valve (angular signal of electric control valve feeds back to controller), if still can not requirement be reached in official hour temperature, then controller outputs signal again, electric control valve is intensifying valve again, by that analogy.Namely touch-screen display is used to indicate the temperature of each temperature sensor, the output quantity of electric control valve, also for touching each information parameter of input, as temperature is arranged.In order to improve precision, temperature sensor selects highly sensitive product.
Controller can select single-chip microcomputer as control chip.Controller comprises the analog to digital conversion circuit etc. for temperature sensor.
The thermal current of described several valves blowout meets, and the medium temperature of stack is minimum, and the end face temperature the closer to stack is higher.
It should be noted that, because stack has a pair, if be added to unanimously by the temperature of one of them stack periphery, then the temperature of another one stack cannot compensate, and for this reason, the temperature of the stack periphery that thermal current is heated needs between the senior middle school of two ends low.
Described two valve sets are respectively near the periphery of stack two end faces, and stack wherein refers to output second stack.Common plastic sheeting process equipment has four roll structures and five roll structures, and after the size of second stack of output is adjusted by temperature-compensating, second stack of output coordinates with the stack of output the plastic sheeting exporting qualified thickness.
The present invention has beneficial effect that is rational in infrastructure, easy to use, that can carry out temperature-compensating to stack, can obtain the higher product of the uniformity, reduce plastic film leftover material waste.
