Description
(1) technical field
The present invention relates to film production machinery field, be specially the film clamping device of a kind of film stretching typing or tensioning modular system.
(2) background technology
In the film production manufacture process, when drawing and setting or tensioning typing, all need half-finished two sides of fixed clamp film.When for example Kapton is produced, normally form the polyamic acid film through slobbering machine, carry out imidization through high temperature furnace afterwards and form Kapton by polyamic acid resin.To the bilateral of semi-finished product film be gripped in the imidization process, make the film imidization of under tensioning or cross directional stretch state, finalizing the design, to improve the traditional performance of film.Be at high temperature to rely on the clamping device of film both sides when semi-finished product film cross directional stretch, reach the purpose of cross directional stretch the cross force that film applies.Also need fixed clamp film both sides during longitudinal stretching, film is to the center contraction distortion when drawing to avoid indulging.
The clamping device of existing film both sides is that the chain pincers or the pin that are installed on the ring-shaped guide rail parts chain are buckled; Because typing imidization or drawing process all will carry out high-temperature process to film; Reach 400 ℃ like polyamic acid film imidization maximum processing temperature; Chain and on chain pincers or pin buckle and should overcome because the mechanical swelling problem that high temperature brings, also need solve the friction problem in the chain drive process, particularly chain pincers or pin and be buckled in very easily to cause under the high temperature and clip broken or the Tear Film side; The damaged film of side is handled, finalizes the design and opens in the technical process such as folder easily in chain pincers pincers mouth position in follow-up stretching, imidization or pin is buckled the thorn button bit and put and pulled open; Until taking off pincers or dropout, influence the film stretching quality, also cause the film production yield to descend.In addition chain and on chain pincers or pin buckle the mechanical admixture that produces in the gearing friction process and dust etc. the film surface quality descended.
(3) summary of the invention
The objective of the invention is to design the film clamping device of a kind of film stretching typing or tensioning modular system; Be arranged in film stretching typing or the tensioning modular system; Be included in the every side of film the two rows niproll is set, the chain drive that niproll is driven by drive motors, the film side is clamped between two row's niprolls; Niproll carries out clamping to the film side, and can not damage film.
The film stretching typing of the present invention's design or the film clamping device of tensioning modular system; Be included in the rotating roll shaft of installing on the every side heat-insulation wall plate of film of two rows; Roll shaft is vertical with the film direction of advance, on arrange roll shaft and the lower roll axle is relative one by one, roll shaft is horizontally through heat-insulation wall plate; End near film is equipped with niproll, and last row's niproll is tangent one by one with the roll surface of the niproll of arranging down; The other end of roll shaft, one at every interval are equipped with sprocket wheel outside heat-insulation wall plate, and the sprocket wheel dislocation on upper and lower row's roll shaft is arranged.The output shaft that is installed on the drive motors of heat-insulation wall plate is any roll shaft that sprocket wheel is installed, and on the heat-insulation wall plate below two row's sprocket wheels, 2～5 tension wheel shafts perpendicular to heat-insulation wall plate is installed, and rotating regulating wheel is installed on it.Each sprocket wheel is in same plane with each regulating wheel.The sprocket wheel that chain is walked around upper and lower roll shaft successively is connected with each regulating wheel, head and the tail two ends and forms annular.After drive motors starts; Sprocket wheel on its output shaft drives chain; Chain drives the sprocket rotation on each roll shaft, and promptly upper and lower row's niproll is every be to drive the drive roll that rotates by sprocket wheel at a distance from one, and relative with drive roll upward or following niproll be driven voller; The dual-side of film is in respectively between the upper and lower niproll of this side, by upper and lower niproll clamping.Under the frictional force effect of the film between the upper and lower niproll, be pushed and advance at upper and lower niproll.
Said drive motors is a variable-frequency motor, and its motor encoder signal and communication line is connected with Master Control Center, and the rotating speed of Master Control Center control and regulation drive motors keeps whole drawing and setting or each motor speed of tensioning modular system synchronous.
When thin-film width is W, the length s of a niproll is 0.03W～0.25W, and the niproll diameter d is 0.08s～0.80s, and the spacing of the adjacent niproll roll surface of same row is 1.0～10.0mm
For carrying out cross directional stretch, heat-insulation wall plate is divided into three parts, leans on the entrance point leading portion to account for 1/4 to 1/3 of drying tunnel casing total length L, and the middle part accounts for 1/4 to 1/3 of L, leans on the back segment of the port of export to account for 1/3 to 1/2 of L.Leading portion is parallel with back segment both sides heat-insulation wall plate, and the spacing of both sides, middle part heat-insulation wall plate strengthens gradually, and the spacing of back segment both sides heat-insulation wall plate equals draw ratio with the ratio of the spacing of leading portion both sides heat-insulation wall plate.
The heat-insulation wall plate at middle part can be divided into 3～6 sections, and every section row up and down is equipped with 2～5 roll shafts.The heat-insulation wall plate spacing of both sides is identical in same section, and the heat-insulation wall plate spacing of each section both sides strengthens piecemeal.Roll shaft on the heat-insulation wall plate of leading portion heat-insulation wall plate and each section of middle part and tension wheel shaft lengthening; Make sprocket wheel, regulating wheel on sprocket wheel, regulating wheel and the back segment heat-insulation wall plate on it in the same plane, chain can be walked around each sprocket wheel and and regulating wheel at grade successively.
Perhaps, every section heat-insulation wall plate at leading portion, back segment and middle part disposes a drive motors, and the output shaft of the drive motors of each section is any roll shaft that sprocket wheel is installed of this section heat-insulation wall plate.Every section the sprocket wheel of arranging roll shaft up and down is staggered arranges, and 1～2 tension wheel shaft perpendicular to heat-insulation wall plate is installed on the heat-insulation wall plate below this section sprocket wheel, and rotating regulating wheel is installed on it.Each regulating wheel, head and the tail two ends that every section chain is walked around each sprocket wheel and this section of this section successively are connected and form annular.The drive motors code device signal connection of each section is connected with Master Control Center, and the drive motors rotating speed of each section of Master Control Center control and regulation is consistent.
Each roll shaft is installed on heat-insulation wall plate through the bearing that is fixed in the heat-insulation wall plate, and every roll shaft disposes 2 bearings at least.
The advantage of the film clamping device of film stretching typing of the present invention or tensioning modular system is: 1, two row's niproll clamping film sides, the influence that grip is not expanded by elevated temperature heat machinery parts; 2, the niproll that rotates can not cause damage to film, has guaranteed the quality of film imidization or cross directional stretch, helps improving the yield of film production; 3, the niproll that rotates can not produce mechanical admixture and dust etc. in operation process, improved the surface quality of film product.
