After the composite film roll is placed on the roll carrying table 421, one end of the winding shaft enters the groove block 414, the pressing shaft cylinder 411 drives the pressing block 412 to move downwards, one end of the winding shaft is fixed in the groove block 414, the supporting claw structure 332 of the roll supporting mechanism 33 is driven by the second pusher 338 to move to one side of the composite film roll, the supporting arm 3321 is driven by the lifting driver 3324 to lift the composite film roll upwards, at this time, the supporting claw structure 332 is driven by the second pusher 338 to move on the transverse frame 334, the composite film roll is extruded from the winding shaft by the supporting arm 3321 and falls onto the roll carrying table 421, after the composite film is completely extruded, the pressing block 412 is released from the winding shaft, the winding shaft is simultaneously taken away by the hook 321, the supporting arm 3321 of the supporting claw structure 332 is reset, the lifting device 42 descends the composite film to a position, the roll unloader 4 is driven by the moving device 43 to take the lifting device 42 for loading the composite film roll out of the lifting frame 31 along the direction of the track 45, after the composite film roll is taken away by the external logistics equipment, and the lifting device is reset once.
The invention also discloses a production method of the battery diaphragm, which comprises the following steps: after completing steps S1-S4, further comprises:
s5, winding: the winding machine 2 winds the composite film produced by the diaphragm compounding machine 1 into a roll after the composite film is entirely wound;
s6, hanging the coil: the coil lifting machine 3 takes off the composite film coil on the coiling machine 2 and moves to the upper part of the coil unloader 4;
S7, coil stripping: the coil lifting machine 3 pushes the composite film coil to move, and the composite film coil falls onto the coil unloader 4 from the winding shaft;
s8, shaft returning: the winding shaft of the composite film roll under the winding machine 3 hand over to is replaced on the winding machine 2 for winding.
The specific working process of the battery diaphragm composite production line is as follows:
The diaphragm rolls are arranged on the first unreeling mechanism 11, the second unreeling mechanism 12, the third unreeling mechanism 13 and the fourth unreeling mechanism 14 through a row hanging device, the width adjusting driver 1114 is started to respectively adjust the positions of the diaphragm rolls to enable the positions of the diaphragm rolls to be aligned, the layer for producing the composite film or the type of the composite diaphragm are selected according to actual conditions, the diaphragms on different unreeling mechanisms are led into the first composite roller group 114, the second composite roller group 115 or the third composite roller group 116 through the first split roller 133, the second split roller 144 and the fourth split roller 142 to be compounded, the diaphragms are compressed and then are formed into the composite film, the composite film is discharged to the outside of the diaphragm compounding machine 1 through the film discharging roller 118 and enters the reeling machine 2, the composite film is pulled through the whole roll power roller group 21 on the whole roll part 2a, the edge of the composite film is trimmed and cut by the trimming device 23, the tension of the film is regulated by the tension detection device 22 to prevent the composite film from transiting and stretching, the composite film enters the winding part 2b through the upper part of the other side of the whole winding part 2a after the whole winding part 2a turns two turns, the winding roller group 26 pulls the composite film to enter the winding shaft on the feeding sliding table component 28, the winding chuck 288 is actively placed for winding, the pressure roller 271 of the winding roller component 27 follows the thickness change of the composite film roll during winding, pressure is applied to the composite film roll to prevent wrinkles and deflection during winding, the composite film is segmented by the segmentation component 293 before entering the winding shaft, the sliding plate 281 is withdrawn backwards to the side edge of the winding frame 25 after winding is completed, the winding shaft is moved to the outlet side by the first clamping fork 282, the winding shaft is unwound by the first clamping fork 282, the hanging winding mechanism 32 on the hanging machine 3 is moved to the upper part of the winding shaft, the hook claw 321 is driven by the lifter 325 to descend to the winding shaft part, the hook claw 321 grabs the winding shaft, the lifting moving device 327 drives the composite film roll to the upper part of the coil unloader 4, at this time, the coil carrying table 421 of the coil unloader 4 is driven by the scissor lifting mechanism 422 to ascend, the pressing shaft device 41 presses one end of the winding shaft, the coil lifting mechanism 32 unwinds the composite film roll, the support claw structure 332 on the support winding mechanism 33 moves to the lower part of the composite film roll, the support arm 3321 rotates to support the composite film roll, the support claw structure 332 moves along the axial direction of the winding shaft to unload the composite film to the coil carrying table 421, the support arm 3321 rotates to return after the coil unloading is completed, the coil lifting mechanism 32 clamps the winding shaft again, the pressing shaft device 41 unwinds the winding shaft, the coil carrying table 32 returns to the first clamp fork 282 again, the lifter 325 moves to the outside of the hanger 31 under the driving of the lifting moving device 327, the composite film roll is transported by external logistics equipment, and the coil carrying table 421 returns to the lower part of the hanger 31, and the coil unloading action is repeatedly completed.
