The course of work of above-described embodiment is as follows：
(1) under beginning state, cutting membrane knife 2 is in the left end of its stroke（In etc. film to be cut state）, at sliding block 11
In the left end of Rodless cylinder 1, and positioned at the side of the first proximity switch 51, as shown in figure 1, central controller makes 3 position-5 way electromagnetism
The valve element of valve 3 is in an intermediate position, and first 2/2-way magnetic valve 41 and second 2/2-way magnetic valve 42 are in closing
Closed state；
(2) it is extraneous to send corresponding signal, center control to central controller when needing to cut off coating materials using cutting membrane knife 2
Device opens second 2/2-way magnetic valve 42（First 2/2-way magnetic valve 41 is still remained turned-off）, while center control
Device moves the valve element of 3 position-5 way magnetic valve 3, and the air inlet and left working hole for making 3 position-5 way magnetic valve 3 are connected, three five
The right working hole of three-way electromagnetic valve 3 is connected with the right exhaust outlet of 3 position-5 way magnetic valve 3, the then air inlet of 3 position-5 way magnetic valve 3
Mouth air inlet, then air-flow passes through the left working hole of 3 position-5 way magnetic valve 3, the left gas port of Rodless cylinder 1 flows into Rodless cylinder 1
Left chamber, promotes sliding block 11 to move right；Meanwhile, the right chamber of Rodless cylinder 1 is vented by right gas port, and a portion air-flow is successively
Arranged by the right exhaust outlet of the right gas port of Rodless cylinder 1, the right working hole of 3 position-5 way magnetic valve 3,3 position-5 way magnetic valve 3
Go out, another part air-flow passes through the right gas port of Rodless cylinder 1, second 2/2-way magnetic valve 42 and discharges, due to Rodless cylinder 1
Right chamber be vented simultaneously by above-mentioned two paths, therefore the speed that moves right of cutting membrane knife 2 is fast；The state of moving process such as Fig. 2
Shown, moving direction is as shown by the arrows in figure 2；
(3) cutting membrane knife 2 continues to move right, when close to but when not yet reaching the low order end of its stroke, sliding block 11 reaches the
The side of three proximity switch 53, central controller closes second 2/2-way magnetic valve 42, first 2/2-way magnetic valve
41 are still remained turned-off, and then the right chamber of Rodless cylinder 1 is only left paths exhaust, and moving right for sliding block 11 is subject to without bar gas
The relatively strength of the right chamber air of cylinder 1 stops, therefore the speed that moves right of cutting membrane knife 2 slows down, as shown in Figure 3；
(4) cutting membrane knife 2 moves right the low order end for reaching its stroke, when sliding block 11 reaches the 4th 54 side of proximity switch,
Central controller makes the valve core movement of 3 position-5 way magnetic valve 3 to centre position, while first 2/2-way magnetic valve 41,
Two 2/2-way magnetic valves 42 are remained turned-off；Cutting membrane knife 2 again in etc. film to be cut state, as shown in Figure 4；
(5) when needing to cut off coating materials using cutting membrane knife 2 again, the external world sends corresponding signal to central controller, center
Controller opens first 2/2-way magnetic valve 41（Second 2/2-way magnetic valve 42 is then remained turned-off）, while central
Controller moves the valve element of 3 position-5 way magnetic valve 3, and the air inlet and right working hole for making 3 position-5 way magnetic valve 3 are connected, and three
The left bank gas port of left working hole and the 3 position-5 way magnetic valve 3 of position five-way electromagnetic valve 3 connects, then 3 position-5 way magnetic valve 3
Inlet charge, then the right gas port inflow of right working hole, Rodless cylinder 1 that air-flow passes through 3 position-5 way magnetic valve 3 is without bar gas
The right chamber of cylinder 1, promotes sliding block 11 to left movement, meanwhile, the left chamber of Rodless cylinder 1 is vented by left gas port, a portion gas
Stream passes sequentially through the left gas port of Rodless cylinder 1, the left working hole of 3 position-5 way magnetic valve 3, the left exhaust of 3 position-5 way magnetic valve 3
Mouth discharge, another part air-flow passes through the left gas port of Rodless cylinder 1, first 2/2-way magnetic valve 41 and discharges, due to without bar
The left chamber of cylinder 1 is vented simultaneously by two paths, thus cutting membrane knife 2 to be moved to the left speed fast；The state of moving process such as Fig. 5
Shown, moving direction is as arrows in fig. 5；
(6) cutting membrane knife 2 continues to left movement, when close to but when not yet reaching the high order end of its stroke, sliding block 11 reaches the
During two 52 sides of proximity switch, central controller closes first 2/2-way magnetic valve 41, second 2/2-way electromagnetism
Valve 42 is still remained turned-off, and then the left chamber of Rodless cylinder 1 is only left paths exhaust, and being moved to the left for sliding block 11 is subject to without bar
The relatively strength of the left chamber air of cylinder 1 stops, therefore cutting membrane knife 2 is moved to the left speed and slows down, as shown in Figure 6；When cutting membrane knife 2 is moved
When moving high order end, state shown in Fig. 1 is returned to, then start the cyclic process of a new round.
In said process, can also by adjust the first current limiter, the second current limiter, the 3rd current limiter, the 4th current limiter,
More specific meticulously speed of the adjusting slider in its infeed stroke each stage.
