It is respectively sleeved on a locking nut 635, two locking nuts 635 are tightened in two thread segments of bearing pin 633 respectively on 634
Thus being fixed on bearing pin 633 between two supporting arms 631 on 634.
As shown in Figure 1 and Figure 2, in the present embodiment, the overarm 22 of guide rail 3 one end is provided with the first travel switch 9,
Second travel switch 10 is provided with the overarm 22 of guide rail 3 other end, when motor 61 along guide rail 3 is just carrying movable slider 4
To movement, and when so that electric saw machine 5 is moved into place, slide block 4 just can touch the first travel switch 9 first touch
Point 91, now the first travel switch 9 can be by controller control motor 61 counteragent, so that slide block 4 is along guide rail 3
Reverse movement, and when finally making electric saw machine 5 return to initial position, slide block 4 can touch the second travel switch just
10 the second contact 101, now the second travel switch 10 can be out of service by controller control motor 61.In this reality
Apply in example, described gate frame 2 is additionally provided with for preventing electric saw machine 5 and two supporting legs 21 of gate frame 2 from touching
The buffer protection mechanism 7 hitting.In the present embodiment, the concrete structure of described buffer protection mechanism 7 is: propping up at guide rail 3 two ends
One fixed seat 71 is horizontally disposed with respectively on support leg 21, two fixed seats 71 have been arranged with a buffer spring 72 respectively, when
, after the driving effect lower edge guide rail 3 of motor 61 moves into place forward or backwards, the housing 52 of electric saw machine 5 can be with for slide block 4
Buffer spring 72 positioned at the corresponding one end of guide rail 3 mutually touches and gradually slows down, without because of inertia and two of gate frame 2
Support leg 21 collides, and anti-locking apparatus damage.
The using method of the projection screen scale guillotine being easy to adjust described in the utility model is as follows: projection screen is placed
On the table top 11 of workbench 1, and cutting of projection screen is made to hold the both sides being located at cutting groove 8 with remaining end respectively.Then open
Galvanic electricity saw 5 makes saw blade 51 high-speed rotation, then starts motor 61 so that drivewheel 62 starts to rotate forward, and passes through
Rack synchronous band 65 band movable slider 4 is positive mobile along guide rail 3 so that the saw blade 51 of electric saw machine 5 along cutting groove 8 to projection screen
Carry out straight cutting.After electric saw machine 5 cuts to projection screen and puts in place, the housing of electric saw machine 5 52 and the buffering positioned at this side of guide rail 3
Spring 72 mutually touches and so that the translational speed of electric saw machine 5 gradually slows down, it is to avoid collide with gate frame 2 because of inertia,
Meanwhile, slide block 4 can touch the first contact 91 of the first travel switch 9 just, and the first travel switch 9 passes through controller
Control motor 61 counteragent so that drivewheel 62 rotates backward and passes through rack synchronous band 65 band movable slider 4 along guide rail 3
Reverse movement, so that electric saw machine 5 is gradually return.When electric saw machine 5 will be retracted into initial position, the housing of electric saw machine 5
52 due to touch with buffer spring 72 positioned at electric saw machine 5 initial position homonymy and make the translational speed of electric saw machine 5 gradually
Slow down, it is to avoid collide with gate frame 2 because of inertia, and now slide block 4 can touch the second travel switch just
10 the second contact 101, the second travel switch 10 controls motor 61 to quit work by controller, and now electric saw machine 5 moves back
Return to initial position, the process that entirely cuts completes.
When rack synchronous band 65 is elongated because of the reason such as aging, when needing re-tensioning rack synchronous band 65, only need to unscrew
Two locking nuts 635 on each fixed mount 63, then by bearing pin 633 to adjusting the outer side shifting of gap 632, up to rack synchronous
Band 65 is by after re-tensioning, then tightens two locking nuts 635 on each fixed mount 63 successively.
The projection screen scale guillotine being easy to adjust described in the utility model has the advantage that one, cuts process ten
Point quick, it has been obviously improved work efficiency, and decreased the consumption of manpower, suitable large-scale batch production；2nd, pass through to make
Projection screen is cut electricity consumption saw so that trimming impulse- free robustness, and by the guide rail guidance quality superior to electric saw machine, thus
Make the trimming of projection screen straight neat；3rd, by making the position that each driven pulley is bearing on respective fixed mount all adjustable
Section, be capable of the tensioning degree of adjusting gear rack Timing Belt, when rack synchronous band because aging and elongated when, can by adjust each driven
Wheel is bearing in the position on respective fixed mount so that rack synchronous band is by re-tensioning, need not be replaced as frequently as new tooth bar same
Step band just can ensure the efficiency of transmission of power, reduces production cost.
