Plastic film thickness controller
Technical field
The utility model relates to plastic film technical fields, specially plastic film thickness controller.
Background technique
The thickness control of plastic film is always to perplex the problem of manufacturer, and plastic film thickness is to lean on currently on the market
Operator's experience and complicated multiple adjustment are corrected to realize.The raw material of different formula and different batches all needs operator
It manually adjusts, worker needs sampling observation in real time, increases labor intensity and unstable product quality.
Main disadvantage has: control precision is low.Because extrusion output, which is affected by the external environment, in extrusion process generates variation,
The raw material extrusion output of different trade mark differences manufacturer production is different, and the thickness of plastic film is caused to change, and generates waste product
And improve production cost;Worker needs every volume measurement, if production plastic film, because thickness measures thickness in 0..4-0.08mm
Degree is inconvenient, can only be controlled by way of weighing, increases labor intensity of workers, improves recruitment cost.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
In the description of the utility model, it should be noted that term " center ", "lower", "left", "right", " is erected at "upper"
Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only
For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific
Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.In addition, term " the
One ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.
Referring to Fig. 1, the utility model provides a kind of technical solution: plastic film thickness controller, including shell 1, storage
Hopper 2, cylinder 3, valve plate 4, weigh hopper 5, electronic scale 6, extruder 7 and electronic valve 8, the shell 1 are internally provided with storing
Bucket 2 is provided with valve plate 4 on the downside of the storage hopper 2, electronic valve 8 is provided on the right side of the valve plate 4, is arranged on the right side of the electronic valve 8
There is cylinder 3, weigh hopper 5 is provided on the downside of the cylinder 3, electronic scale 6, the electronics are provided on the downside of the weigh hopper 5
Extruder 7 is provided on the downside of scale 6, the shell 1 is internally provided with storage hopper 2, shell 1 and storage hopper 2 and uses welded connecting, institute
It states and is provided with catch bar among cylinder 3 and electronic valve 8, be fastenedly connected using bolt, the shell 1 passes through with extruder 7
Discharge port connection, the valve plate 4 are fastenedly connected with electronic valve 8 using bolt, and the cylinder 3, valve plate 4 is respectively welded at storage
The downside of hopper 2, electronic scale 6 are fixed by the bracket in 1 inner wall of shell, 2 downside of weigh hopper, and electronic scale 6 and weigh hopper 5 are matched
Close using can the real time measure extruder discharge quantity, guarantee product quality while save raw material, extruder 7, which can be adjusted at any time, to be led
Draw speed, so that the film thickness for reaching production is consistent, improves yield rate and production efficiency, electronic valve 8, cylinder 3 and valve plate 4
Cooperation can save feeding and blanking time, it is either artificial in production of plastic film to rise to improve working efficiency
In the case of the fluctuation of 7 extrusion output of reduction of speed or extruder, production film thickness uniformity can be realized, because of hauling speed
Always the proportionate relationship kept constant automatically with extrusion output guarantees to save raw material under the premise of product quality, improves yield rate
And production efficiency, reduce labor intensity of workers.
The utility model key point is that the valve plate 4 of 2 lower section of storage hopper periodically closes certain time length, passes through measurement weighing material
The reduction speed for 5 weight that struggle against is extruded velocity.According to extruded velocity can adjust automatically hauling speed, can also be according to hauling speed
Adjust automatically extruded velocity, to realize production film thickness uniformity.
The utility model can also realize that extrusion output is matched with hauling speed automatically, i.e. PLC is counted automatically according to hauling speed
It calculates required extrusion output and automatically adjusting 7 revolving speed of extruder makes extrusion output reach desirable value.
Working principle: after the normal production of plastic film unit booting, start this controller automatic control mode, 2 storage hoppers
4 valve plates are closed certain time length automatically by the timing under PLC control of 3 cylinders and solenoid valve of lower section, and the raw material of 2 storage hoppers is not at this time
It is fallen into 5 weigh hoppers again, the raw material continuous uniform in 5 weigh hoppers is fallen into 7 extruders, constantly measures 5 by 6 electronic scales
The reduction of raw material weight in weigh hopper obtains the instantaneous extrusion output of 7 extruders, and PLC is calculated automatically to be needed under this extrusion output
The hauling speed wanted, and adjust automatically traction reaches required hauling speed, to realize the thickness uniformity of plastic film.
