Description
Technical field
The utility model relates to the relaxation device in a kind of polyester film trailer system, especially relates to a kind of relaxation device of thick low hot shrinkable polyester film.
Background technology
Along with the continuous development of electron trade, the demand of thin film switch, flexible print circuit board etc. is grown with each passing day, the low thermal shrinkage heavy duty polyester film is had broad application prospects.Also need the same with thin gauge film of thick low hot shrinkable polyester film (film thickness is at 0.075mm-0.3mm) is prepared from through longitudinal stretching and cross directional stretch technology.The low thermal shrinkage of heavy duty polyester film mainly obtains by adjusting guide rail width and heat treatment period and temperature at present, though its lateral shrinkage can reach zero, vertically shrinkage factor is also solved fully.Because of film in length and breadth two to shrinkage factor inconsistent, bring adverse influence for the processing of subsequent product, limited the popularization and the use of end product to a certain extent.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, under the prerequisite that does not influence the polyester film lateral shrinkage, can obviously reduce the relaxation device of the thick low hot shrinkable polyester film of its vertical shrinkage factor.
The utility model is that the technical scheme that achieves the above object is: a kind of relaxation device of thick low hot shrinkable polyester film, comprise a pair of nip rolls and preceding cooling roller and back cooling roller on the frame are installed, preceding cooling roller is connected with first drive unit with back cooling roller, and the cooling tube in preceding cooling roller and the back cooling roller be installed in before the cooling roller and after cool off the roller two ends swivel joint be connected and communicate, import and export on the swivel joint are connected with cooling system by pipeline respectively and communicate, it is characterized in that: also install two on the described frame between nip rolls and preceding cooling roller and be used for lax preceding heating roller of film and back heating roller, preceding heating roller is connected with second drive unit with back heating roller, before in heating roller and the back heating roller heat pipe be installed in before the heating roller and after heat the roller end swivel joint be connected, the import and export of swivel joint are connected with heat exchanger by pipeline respectively.
The utility model is by carrying out local improvement to trailer system, heating roller before and after having set up two between nip rolls and the cooling roller, and two heating rollers are by driving device controls independently, therefore when the film with certain linear velocity when horizontal stretching exports out, film is during through two heating rollers, the vertical element chain that does not obtain fully as yet relaxing can vertically further relaxed, under the prerequisite of the suitable membrane tension of control, suitably reduce the linear velocity of two heating rollers, even the linear velocity of heating roller suitably is lower than horizontal linear velocity of pulling out mouthful film, make film vertically obtain fully lax after, again through two cooling roller cooling and shapings, vertical shrinkage factor of polyester film obviously reduces, make the thick low hot shrinkable polyester film in length and breadth two to the shrinkage factor basically identical.The utility model only needs trailer system is carried out local improvement, just can control the vertical and horizontal shrinkage factor of thick low hot shrinkable polyester film, and is economical and practical.
