Abstract
The invention provides a polyimide film bidirectional draw-off mechanism, which is characterized by comprising two cylindrical roll shafts, two annular steel bands and a plurality of connecting rods with a same length. The two cylindrical roll shafts are in parallel and have spacing therebetween; the two annular steel bands are parallel encircling around two ends of the two cylinder roll shaft; a plurality connecting rods are arranged between the two steel bands and perpendicular to a steel band extension direction; two ends of each connecting rod are respectively connected with interior surface of thee steel bands. The invention has simple structure, no complex machinery mechanism like a guide rail, low manufacture costs and high performance reliability.
Description
Technical field
The present invention relates to Kapton preparation facilities technical field, especially a kind of polyimide film bidirectional draw-off mechanism.
Background technology
At present, the two-way draw-off mechanism adopting in Kapton production process substantially: longitudinally utilize the traction force tractive of film take-up, laterally pulling device is that the chain folder for horizontal tractive or nail-plate or steel band are arranged on to guide rail.Laterally traction force will rely on chain folder or nail-plate or the steel band lateral confinement power of guide rail to fixed film, and chain folder or nail-plate or steel band are synchronized with the movement with film and pass through high temperature imidization stove on guide rail conventionally.
Because hot imidization at high temperature carries out, the motion of the attaching means of chain folder, nail-plate or steel band on guide rail is to make with lubricator, and complex structure.This makes the manufacturing cost of longitudinal pulling device large, and fault rate is high.
Summary of the invention
In order to solve the problem of mentioning in background technology, the invention provides a kind of novel polyimide film bidirectional draw-off mechanism.
The object of the invention is to be achieved through the following technical solutions:
A kind of polyimide film bidirectional draw-off mechanism, is characterized in that, it comprises two cylindrical roll shafts, two ring steel belts and the identical connecting rod of multiple length;
This two roll shaft be arranged in parallel, and has spacing between it, and two ring steel belt parallel rings are around in the cylinder two ends of this two roll shaft;
Described multiple connecting rod is arranged between two steel bands and is vertical with steel band bearing of trend, and connecting rod two ends are connected with the inner surface of two steel bands respectively.
As the preferred technical scheme of the present invention, described connecting rod is rigidity connecting rod.
As the preferred technical scheme of the present invention, between described each connecting rod and ring steel belt, connect by a cushion block respectively.
As the preferred technical scheme of the present invention, described cushion block is height-adjustable cushion block.
As the preferred technical scheme of the present invention, chain folder or nail-plate for fixing Kapton are installed on described steel band.
As the preferred technical scheme of the present invention, under the connecting rod between described two roll shafts, install one or more for holding up cylindrical roll shaft of support steel band.
Compared with prior art, the present invention possesses following advantage: the present invention is simple in structure, without complicated mechanical mechanisms such as guide rails, and low cost of manufacture, performance reliability is high.
Brief description of the drawings
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
Fig. 1 is front view of the present invention;
Fig. 2 top view of the present invention;
Fig. 3 is the enlarged diagram of the annexation of connecting rod of the present invention and steel band.
Detailed description of the invention
As shown in Figure 1 to Figure 3, this polyimide film bidirectional draw-off mechanism comprises two identical cylindrical roll shafts 30, two ring steel belts 10 and the identical connecting rods 20 of multiple length.Between this two roll shaft 30, there is spacing, article two, ring steel belt 10 is arranged at respectively the cylinder two ends of this two roll shaft 30, and second ring steel band 10 is parallel, two ring steel belts 10 are connected by multiple connecting rods 20 vertical with steel band 10 bearing of trends that are arranged between two steel bands 10, form guipure; And the plurality of connecting rod 20 is all arranged at the same face of steel band 10, the two ends of multiple connecting rods 20 are connected with the inner surface towards roll shaft 30 of this second ring steel band 10 respectively, and like this, steel band 10 does not directly contact with roll shaft 30, is provided with connecting rod 20 between the two.Described connecting rod 20 has rigidity, is connected, by the distance between the controlled steel strip 10 of height and the connecting rod 20 of adjusting cushion block 40 between each connecting rod 20 and steel band 10 by a cushion block 40.One is installed on connecting rod between two roll shafts 30 20 times for cylindrical roll shaft 50 holding up support steel band.
Chain folder or the nail-plate of fixing Kapton can be fixed on steel band 10.
By this installation or the guipure that chain folder that fixing Kapton uses, nail-plate be not installed be placed in high temperature imidization stove obtain can the imidization of two-way tractive Kapton industrial equipment.
In the production of Kapton, be Polyamic Acid Film to be pressed from both sides by chain or nail-plate or bonding method are fixed on steel band 10, steel band 10 is synchronized with the movement and realizes imidization process by high temperature imidization stove with film.
The present invention does not limit above-mentioned embodiment, and all distortion based on design concept of the present invention all belong in the scope that the present invention protects.For example: the number of described cylindrical roll shaft can also be multiple, and the radial dimension of multiple roll shafts can be identical, can be not identical yet.
Apparatus structure of the present invention is simple, without complicated mechanical mechanisms such as guide rails, and low cost of manufacture, performance reliability is high.
