Description
Technical field
The utility model relates to the technical field of cast film line, more specifically, relates to a kind of high speed cast film line.
Background technology
Casting films is a kind of tensionless winkler foundation, the nondirectional flat crowded film produced by the quenching of melt curtain coating, is divided into simple curtain coating and multi-layer co-extruded curtain coating two kinds.The cast film production of China is started late, basis is comparatively weak, but development speed is very fast, and grow through the developments of nearly 20 years, cast film processing industry has had the rising industry of suitable production capacity and the level of production in the packaging industry of China.
Entered for 21st century under the casting films market demand promotes, domestic cast film line makes significant progress, and domestic casting apparatus international competitiveness strengthens day by day.But, domestic cast film line starts from foreign introduction of production line most, nowadays update is faced with, but regrettably, according to State General Administration of Customs's data statistics, fund 5,800 ten thousand yuan is about needed from external introduction 5 layers of coextrusion, gross investment is at about 8,000 ten thousand yuan, price is very expensive, and domestic cast film line is due to the impact of frame for movement and the unreasonable layout between production equipment, do not realize high-speed production, this is because the high-speed production of casting films is higher to technological process, film needs multiple operation process, therefore the casting films production equipment that independent research goes out superior performance is badly in need of.
The essential structure of now domestic cast film line is: comprise extrusion device, casting device, cooling device, draw-gear and wrap-up, some device usually in these devices shares a motor, by same drive and control of electric machine.When the casting films lineman of above-mentioned structure does, have the following disadvantages: operating process is loaded down with trivial details, the load of single buncher transmission is comparatively large, and unstable properties, affect the steady running of complete machine, production efficiency is low, and the tension adjustment precision of casting films is not high.
Summary of the invention
In order to solve prior art Problems existing, the utility model provides a kind of and improves casting films tension adjustment precision, the casting films high-speed production lines that can steadily operate, and the technical scheme of employing is as follows:
A kind of high speed cast film line, comprises frame, described frame is provided with extrusion device, be disposed with casting device, measuring thickness device, draw-gear and wrap-up below described extrusion device.
After adopting technique scheme, extrusion device, casting device, cooling device, measuring thickness device, draw-gear and wrap-up position arrangement are reasonable, improve the speed of production of casting films.
Further, described measuring thickness device includes the thickness gauge for detecting casting films thickness.
The utility model adopts advanced closed-loop automatic measuring thickness system to carry out Thickness sensitivity to from casting device casting films out, can the thickness parameter of accurate Dynamic Announce film, and can set different detections and scan frequency.
As preferably, cast film line of the present utility model also comprises the corona unit for carrying out sided corona treatment to the casting films through Thickness sensitivity, described corona unit comprises corona bracket, described corona bracket is provided with wrap up in and twines casting films and rotating corona is excellent, the left and right sides of described corona rod is respectively equipped with rotating first and cranks arm and second to crank arm, wherein any one crank arm be provided with casting films can be pressed on corona rod side face on and rotating pressure bar, corona generating device is provided with outside described corona rod, described corona generating device can carry out sided corona treatment to wrapping up in the casting films outer surface twined on corona rod side face, described corona bracket is also provided with the driving rod that casting films is advanced and transmits the transmission rod of casting films.
Particularly, described first cranks arm is provided with transmission rod, and described second cranks arm is provided with pressure bar.
Particularly, described first cranks arm is provided with pressure bar, and described second cranks arm is provided with transmission rod.
Casting films surface property is lower, and directly in its surface coating or printing, color easily comes off, therefore arranges corona unit, carries out sided corona treatment to the casting films of carrying out Thickness sensitivity through measuring thickness device.Print after sided corona treatment is carried out on casting films surface, color difficult drop-off, appearance is good again.And the cast film machine manufactured in the industry at present, the design of its corona treatment plant is reasonable not, is changeless, can not changes the corona surface of casting films according to technological requirement to the corona surface of casting films.And the corona unit of the application is according to the needs of actual process, when needing the lower surface of corona casting films, on cranking arm second, pressure bar is installed, install on cranking arm first and transmit rod, select casting films to wrap up in from the right and twine corona rod, transmission rod on cranking arm by first again, pulls out through driving rod; When needing the upper surface of corona casting films, on cranking arm first, pressure bar is installed, install on cranking arm second and transmit rod, select casting films to wrap up in from the left side and twine corona rod, transmission rod on cranking arm by second again, pull out through driving rod, thus reach can the requirement of corona casting films upper surface or lower surface.
As preferably, cast film line of the present utility model also comprises the film that unloads be connected with wrap-up and shifts frame.
As preferably, extrusion device described in the utility model adopts PID temperature control technology.
In the utility model, described extrusion device, casting device, measuring thickness device, draw-gear and wrap-up can also adopt driven by servomotor to control respectively.Each device has respective motor, facilitates operating process, and the load of motor is all little, ensure that the steady running of casting films equipment complete machine, improves the speed of production of casting films production equipment, improve the tension adjustment precision of casting films simultaneously.
The beneficial effects of the utility model: cast film line of the present utility model is rationally distributed, can realize casting films high-speed production, and make improvements traditional corona unit, make casting films production equipment can change the corona surface of casting films according to technological requirement.
