Fig. 1 to Fig. 3 is refer to, is that the COF of the better embodiment of the utility model one carries strainer, to ensure
Tensile force suffered by COF carrier bands 70 is constant；COF carrier band strainers include substrate 10, parallel interval is arranged on the one end of substrate 10
The first roller 20 and the second roller 30, the guide roller 40 installed in the other end of substrate 10, installation driving on the substrate 10
Device 50 and the shifting roller 60 for connecting drive device 50；COF carrier bands 70 are after cutting and removing COF from guide roller
Transmitted after bypassing the wherein side at the top of the second roller 30, the bottom of shifting roller 60 and the first roller 20 to the external world 40 sides
Rewinding motor on carry out coiled strip.Position of the shifting roller 60 between the first roller 20 and the second roller 30, and pass through
Drive device 50 drives shifting roller 60 to ensure that COF carrier bands 70 are rushing away from the first roller 20 and the second roller 30 so as to reach
Cut the purpose that suffered tensile force is constant during COF.It is to be appreciated that in other embodiments, guide roller 40, which can omit, not to be had to.
Substrate 10 includes fixed part 11 and installation portion 12, and fixed part 11 and installation portion are of an L-shaped structure setting；Fixed part 11
In a side of installation portion 12, fixed part 11 is provided with some bolts hole 13, bolt by bolt hole 13 by substrate 10 with it is extraneous
It is fixedly connected.Installation portion 12 is provided with a bar-shaped trough 14, and the bar-shaped trough 14 is located at the centre position of installation portion 12 and through installation
Portion, and along the longitudinally disposed of installation portion 12.The one side of installation portion 12 is additionally provided with plate 15, and through hole (figure is offered on plate 15
Do not mark), plate 15 is used to install fixed drive device 50.
First roller 20 is arranged on another side of the installation portion 12 with respect to plate 15, positioned at the corresponding bar-shaped trough 14 of installation portion 12
One side, for guiding COF carrier bands 70 to be delivered to extraneous rewinding motor from shifting roller 60.Second roller 30 is arranged on peace
Dress portion 12 is arranged on the same side of installation portion 12, and be located at installation with respect to the another side of plate 15 with the first roller 20
For the corresponding bar-shaped trough 14 in portion 12 with respect to another side of the first roller, the second roller 30 and 20 relative bar-shaped trough 14 of the first roller are symmetrical
Set, the COF carrier bands 70 that second roller 30 is used to convey from the metal type bicker in the external world extend to shifting roller
On 60.The roller 20 of guide roller 40 and first and the second roller 30 are in the same side of installation portion 12, with the second roller 30 along bar
The 14 parallel longitudinal setting of shape groove, guide wheel 40, along default delivery pathways to the second roller 30, avoid COF for COF carrier bands 70
Carrier band 70 produces skew, causes COF to carry 70 front and rear parts and is in contact.
Drive device 50 includes cylinder 51 and sliding block 52.Cylinder 51 is fixed on substrate 10 by wearing the through hole on plate 15
On.The one end of sliding block 52 is connected with cylinder 51, and the other end wears the bar-shaped trough 14 and is fixedly connected with shifting roller 60, and sliding block 52 can
Progress in bar-shaped trough 14 is freely up and down slided；When drive device 50 starts, sliding block 52 is driven by cylinder 51, band movable slider 52
Away from the first roller 20 and the second roller 30；Pressure-reducing valve is additionally provided with drive device 50, pressure-reducing valve can adjust applicable gas
Pressure, moreover it is possible to keep the internal pressure of cylinder 51 stable, it is ensured that the thrust of output is stable；Specifically, when drive device 50 promotes shifting roller
60 to default position when, over time, the air pressure in cylinder 51 can change, influence output thrust, and then influence
The tensile force of COF carrier bands 70；But by the regulation of pressure-reducing valve, the stable gas pressure inside cylinder 51 can be kept, keeps output
Thrust is stable, and then keeps the tensile force of COF carrier bands 70 constant.
Shifting roller 60 be located at installation portion 12 with respect to drive device 50 opposite side, i.e., with the first roller 20, the second roller
30 and guide wheel 40 in the same side of installation portion 12, be fixed on sliding block 52, thus, cylinder driving sliding block 52, the band of sliding block 52
Dynamic shifting roller 60 is moved along bar-shaped trough 14 away from the first roller 20 with the second roller 30, so as to control COF to carry before and after 70
Tensile force it is constant.
Refer to Fig. 4, the COF carrier band strainer work when, COF carrier band 70 along the roller 30 of guide roller 40 and second from
Extraneous metal type bicker is extended in shifting roller 60, the top extension of bottom and the first roller 20 around shifting roller 60
To the rewinding motor in the external world；Before COF carrier band strainers start, extraneous metal type bicker carries 70 feedings to COF, makes
The one end for obtaining the connection metal type bickers of COF carrier bands 70 are in relaxed state；When COF carrier band strainers start, rewinding motor
Static, drive device 50 drives shifting roller 60 to push COF carrier bands 70, and shifting roller 60 drives COF carrier bands 70 along bar-shaped trough
14 move away from the first roller 20 and the direction of the second roller 30；Simultaneously as one end of COF carrier band connection rewinding motors is in and opened
Tight state, one end of COF carrier band connection metal type bickers is in relaxed state, so COF carrier bands 70 are partially toward shifting roller
60 and the direction of the first roller 20 movement；When shifting roller 60 presses to default position, COF carrier bands 70 stop movement, now COF
State of the carrier band in tensioning, metal type bicker start to be punched work；After the completion of blanker makees, extraneous rewinding motor starts,
Now, shifting roller 60 by COF carrier bands 70 pulling and along bar-shaped trough 14 towards close to the first roller 20 and the side of the second roller 30
To movement, and cylinder 51 coordinates contraction；When shifting roller 60 moves default position, rewinding motor stops；Above-mentioned operation
Circulation work.
COF of the present utility model carrier band strainer passes through the mobile rolling installing drive device 50 He can move up and down
Wheel 60 so that the tensile force before and after the COF carrier bands 70 being wrapped on strainer keeps constant, improves determining for COF carrier bands 70
Position precision and die cutting accuracy, so as to improve the precision and stability of product；By installing pressure-reducing valve in drive device 50,
So as to which the thrust of cylinder 51 is controlled by pressure-reducing valve, atmospheric pressure value can be adjusted, moreover it is possible to keep internal pressure stable, it is ensured that to be delivered to shifting roller
Thrust on 60 is stable, is ensured with this constant before and after tensile force suffered by COF carrier bands 70.
