Drawings
FIG. 1 is a schematic top view of the present invention;
in the figure, 1, a support frame, 2, a screw rod, 3, a threaded hole, 4, a chuck, 5, a sliding mounting plate, 6, a guide rod, 7, a guide rod sleeve, 8, a guide rod abdicating hole, 9, a pressure sensor, 10, a second rotating shaft abdicating hole, 11, a rotating shaft, 12, a convex edge, 13, a first rotating shaft abdicating hole and 14, a motor are arranged.
Detailed Description
A roll changing device for polyimide film production comprises two support frames 1, a sliding mounting plate 5, a guide rod 6 and a lead screw 2, wherein two ends of the guide rod are fixedly connected with the two support frames respectively, the sliding mounting plate is provided with a first rotating shaft abdicating hole 13, a threaded hole 3 and a guide rod abdicating hole 8, the guide rod passes through the corresponding guide rod abdicating hole to enable the sliding mounting plate to slide along the guide rod, one of the support frames is provided with a second rotating shaft abdicating hole 10 corresponding to the first rotating shaft abdicating hole, the first rotating shaft abdicating hole and the second rotating shaft abdicating hole are respectively and rotatably provided with a rotating shaft 11, the first rotating shaft abdicating hole and the second rotating shaft abdicating hole are respectively provided with a bearing seat and a bearing, the free end parts of the two rotating shafts are respectively and fixedly sleeved with a chuck 4, the chuck is in a frustum shape, and a plurality of convex ribs 12 are arranged on the frustum along the extending direction, the screw rod is arranged between the two support frames and penetrates through a threaded hole of the sliding mounting plate to be in threaded fit with the sliding mounting plate.
Further, guide bar and lead screw are located the bilateral symmetry setting of pivot respectively, fixed mounting has guide bar cover 7 on the sliding mounting board, fixed mounting has pressure sensor 9 on the guide bar cover, and when the winding polyimide film reached certain thickness on the spool, will touch pressure sensor, pressure sensor will give the controller with information transfer, controller controlgear stop operation.
Preferably, the screw is driven in rotation by a motor 14.
When the hollow scroll is installed before winding, the reel changing device for producing the polyimide film only needs to rotate the lead screw to drive the sliding installation plate to slide outwards to keep the distance between the two chucks away, the chuck at the fixed end is inserted into the hollow part at one end of the hollow scroll, then the lead screw rotates reversely to drive the sliding installation plate to slide inwards, and the chuck at the sliding end is inserted into the hollow part at the other end of the hollow scroll and props up the hollow scroll.
When the rolling finishes and needs to be changed rolls, the polyimide film roll is only needed to be supported below, then the screw rod rotates, the sliding mounting plate slides outwards along the screw rod, the polyimide film roll is loosened, then the polyimide film roll is dragged outwards, the other end of the polyimide film roll is separated from the chuck, and the polyimide film roll can be taken out, so that the roll changing is completed. The technical scheme of the utility model has the advantages of simple structure, convenient operation of winding and changing, time saving and labor saving.
And because the chuck is the frustum shape, when the internal diameter of hollow axle is different, need not to change the chuck, only need control the rotatory revolution of lead screw, thereby control sliding mounting panel's stroke, make the hollow axle card can adjust at the different positions of chuck frustum, and be equipped with a plurality of protruding stupexes along the extending direction on the frustum, can not skid between hollow axle and the chuck, polyimide film rolls up the width difference simultaneously, the length of hollow spool is different promptly, also need not dismouting adjustment sheet, can control the chuck through sliding mounting panel's removal and press from both sides the hollow spool tightly equally, and the dismouting of the scope of regulation is more extensive than the adjustment sheet.
In conclusion, the roll changing device for producing the polyimide film, provided by the utility model, has the advantages of simple structure and convenience in roll changing, and can adapt to reels with different inner diameters and different lengths.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
