Meanwhile, all technical characteristics in the invention can be interactively combined on the premise of not conflicting with each other.
Referring to fig. 1, a composite slitting machine includes: the device comprises an unreeling device 100, a slitting device 200 and a reeling device 300, wherein tension adjusting devices 400 are arranged between the slitting device 200 and the unreeling device 100 as well as between the slitting device and the reeling device 300; the slitting device 200 comprises a slitting knife and a feeding end, a dust suction mechanism is further arranged on the slitting device 200 and comprises a dust suction port, and the dust suction port is located between the slitting knife and the feeding end.
Specifically, the dust suction mechanism can comprise a negative pressure pump and a dust collection bag, the negative pressure pump is communicated with a dust suction port, the dust suction port is communicated with the dust collection bag, when the negative pressure pump is started, certain negative pressure can be formed in the dust suction port, and the negative pressure can suck away the dust after stripping and bring the dust into the dust collection bag.
Further as a preferred embodiment, the slitting device 200 further comprises a driving mechanism and a transmission mechanism, the driving mechanism drives the slitting knife to rotate through the transmission mechanism, and the transmission mechanism comprises a CVT transmission case.
In a further preferred embodiment, a storage table 500 is further disposed between the tension adjusting device 400 and the slitting device 200.
Further as a preferred embodiment, the storage platform 500 includes a trench 510, a swing bridge 520 and an expansion link 530, one end of the swing bridge 520 is hinged to the slitting device 200, the other end is freely suspended, and the middle of the swing bridge 520 is connected to the expansion link 530.
Further as a preferred embodiment, one end of the telescopic rod 530 is hinged in the trench 510, and the other end is hinged with the swing bridge 520.
Further, as a preferred embodiment, the unwinding device 100 includes an unwinding frame 110, a supporting arm 120 and a pressing rod 130, and both the supporting arm 120 and the pressing rod 130 are rotatably connected to the unwinding frame 110.
Further as a preferred embodiment, one end of the supporting arm 120 is provided with a groove; one end of the pressing rod 130 is provided with a pressing wheel 140.
Further as a preferred embodiment, the tension adjusting device 400 includes a balloon type tension mechanism 410.
In operation, the composite material is placed in a roll, which includes a roll core placed in the groove of the bracket arm 120. During loading, the winding core can be slightly released in the groove by swinging the support arm 120 downwards, then the support arm 120 is lifted, and meanwhile, the pressing rod 130 is put down, so that the pressing wheel 140 on the pressing rod 130 always presses the coil stock, and the smooth loading of the composite material is ensured;
then the composite material enters the tension adjusting device 400, passes through the material storage table 500 and is sent to the slitting device 200, the slitting knife in the slitting device 200 slits the composite material with larger width into a plurality of composite materials with smaller width, and the dust can be sucked cleanly by the dust suction mechanism because the composite materials can generate dust when being slit; the slit composite material then passes through another tensioning device 400 again, is then fed to a take-up device, and is rewound. The rolled composite material can be sent to the next process.
By utilizing the two tension adjusting devices 400 at the front and the rear of the slitting device, the composite material is always in a tight state when being slit, and the slitting precision is improved. Moreover, a CVT gearbox is arranged in the slitting device 200, and the rotating speed of the slitting knife is adjusted in real time by the CVT gearbox, so that a better cutting effect is achieved.
The CVT gearbox that uses in this embodiment, similar to the CVT gearbox in the car, in transmission system, traditional gear is replaced by a pair of pulley and a steel belt, and every pulley is the V-arrangement structure of constituteing by two conical disks in fact, and the engine shaft is connected the small pulley, sees through steel belt drive big pulley. CVT drive pulleys are odd in construction and are split into movable left and right halves that can be relatively close together or separate. The tapered disc can be tightened or expanded under the action of hydraulic thrust to extrude the steel sheet chain so as to adjust the width of the V-shaped groove. When the conical disc moves inwards and is tightened, the steel sheet chain moves towards the direction (centrifugal direction) outside the circle center under the extrusion of the conical disc, and conversely moves towards the inside of the circle center. Thus, the diameter of the disc driven by the steel sheet chain is increased, and the transmission ratio is changed. The principle of CVT is different from the common gear box, and several groups of gears with different sizes are combined under the control to form different speed ratios. The pedals of the bicycle drive the wheels to rotate at different speeds through the large and small wheel discs and the chain. Because the thrust generated by different forces to each group of gears is different, the rotating speed output by the gearbox is changed, and the non-stepped slow rotation is realized.
When the cutting speed of the slitting is not matched with the speed of the unwinding device 100 or the winding device 300, the telescopic rod 530 can act to drive the swing bridge 520 to swing, and when the swing bridge 520 swings downwards, the rolled materials fall into the trench 510 under the action of gravity because the rolled materials cannot be supported by the swing bridge 520; when the speed starts to be matched, the swing bridge 520 swings upwards, so that the upper surface of the swing bridge 520 is parallel to the feeding direction of the coil stock, and the swing bridge 520 supports the coil stock. Preferably, the upper surface of the swing bridge 520 may be provided with rollers. Reducing the friction between the web and the upper surface of the swing bridge 520.
While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments shown, but is capable of various modifications and substitutions without departing from the spirit of the invention.
