The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Below in conjunction with concrete accompanying drawing, realization of the present invention is described in detail.
Specific embodiments of the invention are as shown in Fig. 1~Fig. 8, a kind of automatic high-efficiency material retractable system, comprise fixing base 8 and engine installation, fixing base 8 be provided with discharge plate 1, on fixing base 8, be also provided with guide wheel device, material conveying platform 5, counter wheel device and the rewinding wheel 13 along web feed path, arranged successively; Counter wheel device comprises counting pinch roller 6 and counter wheel 9, is also provided with can make to count pinch roller 6 and compress with counter wheel 9 or separated clutch control mechanism, and then conveniently carries or install/change diaphragm material on fixing base 8.
In the present embodiment, counter wheel device is positioned at the below of material conveying platform 5, and counter wheel 9 is positioned at the below of counting pinch roller 6.Loose slot 23 on fixing base 8, clutch control mechanism comprises and is movably installed in these loose slot 23 places and for the lateral adjustments bar 22 of counting pinch roller 6 wheel shafts, the vertical link 19 connected with lateral adjustments bar 22, the extension spring device being connected with vertical link 19 are installed, and is located at the driving wheel device between extension spring device and connecting rod 19.Vertical link 19 is positioned at the below of lateral adjustments bar 22, and lateral adjustments bar 22 is provided with subtended angle fulcrum roller 20, and lateral adjustments bar 22 can be around subtended angle fulcrum roller 20 cws or left-hand revolution.Clickwise just makes to count pinch roller 6 rotations and upwards opens, otherwise make to count pinch roller 6 rotations, compresses downwards.Extension spring device comprises the extension spring 16 being connected with vertical link 19 ends, and the pulling force adjusting screw(rod) 15 being connected with extension spring 16.Extension spring 16 lateral arrangement ,Qi one end are connected with vertical link 19 lower end, and the other end is connected with pulling force adjusting screw(rod) 15.Vertical link 19 ends are provided with connecting rod card wheel 18, and driving wheel device comprises the eccentric wheel 17 of being located on fixing base 8, and on eccentric wheel 17, farthest, distance wheel shaft axle center is provided with for taking turns 18 suitable bayonet sockets with connecting rod card; On eccentric wheel 17 wheel shafts, being also provided with can be with the clutch pressing plate 11 of movable eccentric wheel 17 rotations.
Discharge plate 1, clutch pressing plate 11, counting pinch roller 6, counter wheel 9, guide wheel device and material conveying platform 5 are all positioned at front one side of fixing base 8; Lateral adjustments bar 22, vertical link 19 and eccentric wheel 17 are positioned at the back side one side of fixing base 8.On rewinding wheel 13, blanking latch 12 is also installed, blanking latch 12 is installed on rewinding and takes turns on 13 wheel shafts.Rewinding wheel 13 is connected by drive belt 10 with counter wheel 9.Guide wheel device comprises angle track adjusting wheel 2 and the track adjusting wheel 3 setting gradually, and is also provided with length inductor 4 between described track adjusting wheel 3 and material conveying platform 5.When blowing reaches after preseting length, just stop blowing.Owing to being provided with protective film on material strip on identical interval location, then protective film taking-up one by one is attached on product, when when pasting one of them protective film, just need to suspend blowing.Discharging one end of material conveying platform 5 is provided with oblique angle, and, on the length direction of material conveying platform 5, platform bottom surface is shorter in length than end face length, thereby forms Yi Ge inclined-plane between end face and bottom surface, and, between top edge and inclined-plane, be provided with transition circle cambered surface.
The below of material conveying platform 5 is also provided with Castor 9, and material conveying platform 5 Shang oblique angles are carried and walked around to material strip through material conveying platform 5, then downwards and in opposite direction around to Castor 9, then further around to counting pinch roller 6 and counter wheel 9.Material strip between Castor 9 and material conveying platform 5 is the first material strip section 24, and the angle angle that is positioned at material strip on material conveying platform 5 and is between the second material strip section 25, the first material strip sections 24 and the second material strip section 25 is greater than the angle of bevel that material conveying platform 5 is provided with.Therefore, diaphragm material can automatically strip out in course of conveying on material conveying platform 5, and can protective film not produced and be pulled.And the both sides of discharge plate 1 are also provided with snap fit 26, for convenience detach reloading.Engine installation comprises blowing motor 14 and the rewinding motor 21 being installed on fixing base 8.And, lateral adjustments bar 22 forms one with vertical link 19 can be around the square swivel block of tension force fulcrum roller 20 rotations, the right edge of vertical link 19 is designed with eccentric wheel 17, plays spacing effect, thereby guarantees that the angle of this square swivel block left-hand revolution is constant.Blowing motor 14 in the present embodiment adopts torque motor, and rewinding motor 21 adopts servomotor.
Principle of work of the present invention is as follows:
State shown in Fig. 3 is the state being separated corresponding to counting pinch roller 6 and counter wheel 9.
During normal operation, under the pulling force effect of extension spring 16, connecting rod card wheel 18 holds out against on the arc rotary surface of eccentric wheel 17, and the pulling force of extension spring 16 is enough greatly time, and the bayonet socket on eccentric wheel 17 is positioned at the rightmost side, otherwise is positioned at upper right side or lower right.Now, vertical link 19 is inclined, and counting pinch roller 6 is pressed on counter wheel 9.
When needs are installed or are changed matrix material, manually click clutch pressing plate 11, eccentric wheel 17 rotations, make in connecting rod card wheel 18 bayonet sockets that stick on eccentric wheel 17, vertical link 19 clockwise rotates around subtended angle fulcrum roller 20 with lateral adjustments bar 22, makes to install on the one end of counting pinch roller 6 wheel shafts and move on lateral adjustments bar 22, now, counting pinch roller 6 fixes at certain height under the pulling force effect of extension spring 16, therefore, and also without pressing again clutch pressing plate 11.Now, as shown in Figure 3, vertical link 19 is vertical state, and counting pinch roller 6 is separated with counter wheel 9.
Then, can easily diaphragm material be positioned between counting pinch roller 6 and counter wheel 9, after upper good material, only need click again clutch pressing plate 11, connecting rod card wheel 18 and the bayonet socket on eccentric wheel 17 are separated, count pinch roller 6 under the pulling force effect of extension spring 16, being pressed on counter wheel 9 tightly.
In the above embodiments, owing to counting the pressure of pinch roller 6, be only subject at work the pulling force of extension spring 16, so the pressure of counting pinch roller 6 is constant, make its counting more accurate.
The above embodiments are only the preferred embodiments of the present invention, can not limit interest field of the present invention with this, and therefore, the equivalent variations of doing according to the present patent application the scope of the claims, still belongs to the scope that the present invention is contained.
