Description
Technical field
It the utility model is related to inflation film manufacturing machine technical field, more particularly to a kind of cylindric inflation film manufacturing machine automatic feeding system.
Background technology
The inflation film manufacturing machine of cylindrical plastic film production by dry polyethylene master batch hopper by particle gravity in itself and
Feeding motor extruding enters from hopper, motor driven slant edge face extruding plastics, plastic master batch is promoted forward and squeezes into heating
Barrel, barrel external heat and dissolving as liquid slowly.Melt later liquid plastics by after strainer filtering in die head
Out, cooled down, aided in after inflation by collapser, traction roller group stretches, and receiving mechanism is coiled by the film roll of production.
The speed of traction roller group determines the thickness of production film in general production.Charging motor and traction electric machine frequency are ideally set
Fixed, it is fixed thickness to produce plastic film thickness.This is also the most frequently used maximally effective solution in traditional production, and one
Directly use till today.
The film of production different-thickness needs multiple experiment just to make the thickness that film weight is approximately setting, experiment
During inevitably produce waste material and cause to waste, and because of daytime, the temperature difference at night during film produce, particle
The many factors such as masterbatch density unevenness, the voltage pulsation of power supply can all cause production material undesirable, so making factory in film
Workpeople often produce a coiled strip will carry out the weight of Mick for several times inspections inflation film manufacturing machine grammeter weigh, it is necessary to the material weight looked after be
In desired scope, it is impossible to stop, run at the appropriate speed, but this might not reach desired precision.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, and provides a kind of cylindric inflation film manufacturing machine self-feeding
System, simplify the operating process of inflation film manufacturing machine by digitized control system, improve production film precision, it is inclined to automatically adjust production film in real time
Difference.Real-time display currently produces each index of material, reduces cost of labor, improves the quality of production.
The utility model to achieve the above object, using following technical scheme：
A kind of cylindric inflation film manufacturing machine automatic feeding system, it is characterised in that：Including raw material hopper, weigh hopper, biography of weighing
Sensor and extrusion screw, the bottom of the raw material hopper are connected by hopper valve with the top of the weigh hopper, institute
State the bottom that weighing sensor is arranged on the weigh hopper, the discharging opening of the weigh hopper and the extrusion screw
Feed end connects.
Preferably, the weighing sensor sends weight signal to STM32F103VCT6 chips, STM32F103VCT6
Chip exports enable signal and 0-10V analog output signals, for controlling traction electric machine frequency converter.
Preferably, the output end of STM32F103VCT6 chips is also associated with alarm module and HMI man-machine interfaces.
The beneficial effects of the utility model are:The system, which automatically adjusts charging motor and the cooperation of traction electric machine, makes its output
Film thickness for setting thickness.The film thickness with regard to that can be set need not be tested, and gathers feed weight in real time
Regulation lock can be overcome because of error caused by raw material inequality, not only increased the precision of plastic sheeting weight and saved
Largely as caused by experiment waste material.Solve membrane stress, kick the beam, be blocked up, excessively dilute etc. problem, control accuracy 0.1% with
Inside not only save raw material but also steady quality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is circuit diagram of the present utility model；
Fig. 3 is flow chart of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the present utility model in detail.Such as Fig. 1 and Fig. 2
It is shown, a kind of cylindric inflation film manufacturing machine automatic feeding system, including raw material hopper 1, weigh hopper 2, weighing sensor 3 and extrusion
Screw 4, the bottom of the raw material hopper are connected by hopper valve 5 with the top of the weigh hopper, the weighing and sensing
Device is arranged on the bottom of the weigh hopper, and the feed end of the discharging opening of the weigh hopper and the extrusion screw connects
It is logical.System improves feed hopper, goes out one weigh hopper of increase in hopper blanking.For detecting the weight of charging and then calculating
The flow of charging.According to the thickness of film set control hauling speed, using P I D adjust, according to the feed rate of collection with
And hauling speed calculates the bag weight of current production film.It is that value of feedback is reformed as setting with setting bag by current production film bag recast
Value, using traction electric machine as control object, form closed-loop control.With factually when the data that gather be controlled, when due to daytime,
When the temperature difference at night, particle masterbatch density unevenness, fluctuation of line voltage etc. can make it that film produces weighting or partially light situation,
Controller can adjust back setting value in time.
As shown in Fig. 2 the weighing sensor sends weight signal to STM32F103VCT6 chips,
STM32F103VCT6 chips export enable signal and 0-10V analog output signals, control traction electric machine frequency converter.
The output end of STM32F103VCT6 chips is also associated with alarm module and HM I man-machine interfaces.The purpose of system major control is
Control plastic film thickness in real time, raw material weight and production film length collection are to improve the precondition of control accuracy, so using
Weighing module is acquired, and external structure as above saves described, and primary control object is traction electric machine frequency converter.Control system output makes
Energy signal and 0-10V simulation outputs (being obtained by PWM) control traction electric machine frequency converter, produce for convenience of operation and lack
Material and the alarm of blanking time-out and HM I interfaces, while in order to intuitively show that inflation film manufacturing machine working condition touch-screen shows current production film
Rice number and production film gross weight.
As shown in figure 3, being initialized after system electrification, the setting data read-out for being stored in AT24C256 is reached into HM I, etc.
Treat that HM I send control signal, and collection signal is calculated into data with part in real time and passes the current reality of HM I teaching process personnel back
When data include hopper in material weight, accumulative yield etc. information.
Program wait operating personnel set parameters, after carrying out the preparation before equipment use, press startup by
Button single-chip microcomputer automatically adjusts traction electric machine speed automatically according to setup parameter at any time.Ensure the uniform qualified of production material.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
