Double Extruding Inner-liner Production Line

Posted: 2011-6-15 9:14:22

Application:
Air-cooled double extruding OTR radial tire inner-liner production line adopts air-cooled technology, it mainly produces inner-liner and thin rubber sheets of various width and thickness, which has been proven in use by many customers.

Performance:

According to technological requirements, the production line extrudes the under-liner sheets and rubber sheets applied to inner-liner by cool feeding pin type extruder, which is installed oppositely. After extruding, the sheets are hot compounded at the hoisting composition conveyor. By cooling, cutting and double positions windup devices to center and wind-up the rubber sheets.

Equipment Features：

1、 Two kinds of rubber sheets used for inner-liner compound and build at one time, high production efficiency.

2、 Centering and composition of the rubber sheets under uncooled condition, no bubbles between sheets.

3、 Detecting and tracking the sheet width and position change automatically, as well as adjusting joint position individually, high composition precision.

4、 Measuring the windup length and cutting automatically.

5、 High air tightness of rubber sheets, high density of products.

6、 With man-machine conversation operation interface to realize parameters setting, procedure parameters recording, alarm prompt, device movement control, etc.

Host Computer System:

The production line adopts Siemens S7-300 as central control system, and uses POFIBUS-DP net of distributive I/0 to make data communication. By using MPI bus li、

N11e, the control system intercommunicates with host computer software. The host computer provides monitor screen of the production line, it can set and modify production parameters to show the whole machine’s working condition. The production line adopts intelligent instrument to realize temperature control, and keeps the temperature of the relevant parts steadily to be controlled within the range of technological requirements during the production process.
