It is vertical to draw two ends of draw roll, respectively add a set of infrared heating mechanism, ensure the energy of side film good absorption infra-red radiation, to improve
The thickness of side film stretches uniformity and membrane film forming.
The technical solution adopted in the utility model is：A kind of high performance thin film stretching-machine, including draw roll, the draw roll
Lower section is equipped with fixed frame, and the fixed frame connects stretching-machine, is connected with sliding rail on the fixed frame, on the sliding rail
Equipped with sliding rack bearing, cylinder is connected on the sliding rack bearing, the working end of the cylinder is connected with infrared heating pipe, institute
It states infrared heating pipe and draw roll is adapted；The fixed frame is equipped with rotary screw rod, and the rotary screw rod drives on fixed frame
Bottom offset.
The rotary screw rod is equipped with Rocker handle as a further improvement of the utility model,.
As the further improvement of the utility model, the fixed frame is located at the rear and front end of stretching-machine.
The infrared heating pipe is transparent diplopore quartz ampoule, infrared wavelength 2 as a further improvement of the utility model,
~4um, 150~250mm of pipe range.
As the further improvement of the utility model, the infrared heating pipe is apart from 25~40mm of film surface.
The utility model use advantageous effect be：The high performance thin film stretching-machine of this structure in biaxial tension by producing
Two ends of vertical drawing draw roll of polyester film respectively add a set of infrared heating mechanism, ensure side film good absorption infra-red radiation
Energy, and then the thickness for improving side film stretches uniformity and membrane film forming.The film forming of membrane not only can be improved in the utility model
Property and thickness stretch uniformity, and the input and output rate of membrane can be improved, reduces cost.
