Description
Technical field
The present invention relates to film stretching technique fields, more particularly, to a kind of online pretensioning device of film.
Background technique
In plastic packaging industry, winding package is the optimal mode of pallet packing, it utilizes the nerve of stretched film will
Cargo and pallet constraint it is integral, play fixed effect consequently facilitating handling and transport, stretched film before packing use all
It is pre-stretched, is increased by pre-stretching and stretch film strength, while also can be reduced making for stretched film in use
Dosage；The stretching of stretched film mainly uses Pretension Mechanism for Active Drawing to be pre-stretched, and uses two that revolving speed same diameter is different
A roller, due to foring membrane speed between two rollers greater than the state into film speed, in order to compensate between the two
Difference, film can only be stretched, and this stretching is actively to be formed.
For film during stretching with the film after retracting roller retracting stretching, the diameter for furling roller is increasing,
It stretches winding linear velocity under same speed conditions to increase, so that tensioning wheel is by bigger tensile force, thus can be to stretching
Film further generates the effect of stretching, causes the stretching film properties produced in a slight decrease, affects the usability of stretched film
Energy；In addition new retracting roller is needed replacing after retracting roller furls full stretched film, needs to cut stretched film in replacement
Break, traditional mode is manually to be cut off with scissors to stretched film, and not only speed is slow but also shears also not for this shearing by hand
Uniformly.
Summary of the invention
The main purpose of the present invention is to provide a kind of online pretensioning devices of film, can be with retracting roller diameter
Become larger and automatically adjust the position of idler roller, reduce its influence to film properties are stretched, in addition after retracting roller retracting is full certainly
It is dynamic that stretched film is cut off.
To achieve the above objectives, the technical solution adopted by the present invention is：A kind of online pretensioning device of film, including setting
