Description

Film take-up adjusting apparatus

Technical field

The present invention relates to plastics machinery technical field, more specifically to film take-up adjusting apparatus.

Background technology

By production process of plastic products, plastics machinery can be divided into plastic blender tool, plastic molding machinery, plastics secondary operations machinery and the four big classes such as plastic processing Aided Machine or device. The degree of perfection of plastics machinery directly affects plastics semi-products or the quality of goods, yield and cost, thus must be able to adapt to that plastics are compounding and the change of the temperature of the course of processing and stress, and the fused materials performance change caused therefrom, and adapt to the specific condition such as chemical attack and mechanical wear. The customizations of plastics grade, the development of engineering plastics, the appearance of composite, the demand for development plastics machinery of the technology such as plastic product structure large-scale, lightweight and thin-walled property reaches: the complete set for production of articles purpose; At a high speed, laborsaving, automatization, to improve production of articles efficiency; Ensure product specification and the minimum measure of precision of quality error; Energy consumption is low, takes up an area few, and Operation and Maintenance is easy and safety.

Plastic calender is mainly used in the processing equipment producing all types of plastic thin film and PVC calendared artificial leather product manufacturing. It generally has four master rollers or five master rollers, by the compacting of plastics thing uniformly. After plastics are rolled into thin film, it is necessary to rolling is got up, to facilitate transhipment. In prior art, for the wrap-up of rolling plastic sheeting, pretty troublesome when changing wind-up roll, it is typically all and different wind-up rolls is set, to realize alternately continuous rolling plastic sheeting, but the wind-up roll being arranged on inner side is inconvenient to take off after rolling completes, and changes wind-up roll also inconvenient.

Summary of the invention

Instant invention overcomes deficiency of the prior art, existing wrap-up is arranged on the wind-up roll of inner side and is inconvenient to take off after rolling completes, change wind-up roll also inconvenient, provide a kind of film take-up adjusting apparatus, easy to use, it is simple to changing wind-up roll and have adsorption, the setting of multiple wind-up rolls makes rolling enhanced convenience quick, the phenomenon that plastic sheeting is crumpled can be eliminated simultaneously, improve product quality.
