Automatic Control System Research and Development Unit of Large-scale Multi-layer Plastic Sheeting

我国是农膜生产和使用最多的国家,实际年产量超过100万吨,许多的老牌企业生产能力很大,但这些企业设备落后,自动化水平低,因此提高农膜自动化设备技术,产品换代更新,成为许多老牌重量级企业的迫切需求。我国在农膜生产设备的技术方面与国外相比有很大差距,尤其是在大型化生产设备(如大型宽幅压延、大型吹塑薄膜生产设备)领域。本文在目前流行的农膜设备大型化的发展方向引导下,针对我国大型宽幅多层复合农膜设备研发的初级阶段的现状,分析大型宽幅多层复合农膜设备的技术特点与要求,研制了这个设备,以实现宽幅18米的大型宽幅复合薄膜的生产制备,以提高我国农膜设备的自动化水平。

Fanning theca is the mostly produced and employed in our China. Our yearly practical output exceeds 1000,000 tons. Although our mantling acreage occupies the first place of the world and many traditional brand corporations have great throughput, yet their equipments are greatly aging and far drop behind because of low automatization, low precise, low ability of producing new-type fanning theca which possesses various functions and few finished product in breed and output. Therefore, farming theca automatic equipment technique should be graded and produetion update lifted, ~hich is the instance demand for many traditional and significant corporation. There is a long way to go if our farm theca production equipments technique can catch up with those abroad, especially in the field of large-scale production equipment （ such as large breadth pressing extension, and large blow plastic theea production equipments）. With the development of these fairly prevalent theca equipments and the help of the most advanced automatization and procedure monitor production and technique, the pa- per deals with developing new and large modern equipment automatization system, aiming to realize the preparation of large breadth pellicular with the width of more than 15 meters and upgrade the farming theea equipment automatization of our country.
