Specific implementation mode
Below in conjunction with attached drawing, present invention is further described in detail：
Referring to Fig. 1, Fig. 2, a kind of embodiment of the pneumatic centering device of cotton tyre cord of automatic fixed width of the invention, including：Cylinder
Body 10,10 both ends of cylinder body end cap 6, it is fixed in baffle 7, baffle leading screw 8, the piston 14 inside cylinder body 10, the air inlet on cylinder body 10
Hole 9, venthole 15 and mounting rail 5, the end of baffle leading screw 8 are connect with the shaft of a control motor 1, control the control of motor 1
End is connected to a host controller.
For accurately control two it is fixed in baffles 7 spacing, it is ensured that between moving component, between moving component and stationary parts not
It collides, a pair of of baffle position limit switch 11 of setting at the stroke both ends of baffle leading screw 8 rises in the stroke of baffle leading screw 8
An origin detection switch 12 is arranged in beginning position, and the signal output end of origin detection switch is connected to the host controller.
Specifically, a baffle position limit switch 11 in two baffle position limit switches 11 is opened with origin detection
It closes 12 to be mounted on same fixed frame, fixed frame is mounted on close to the position of 1 lower section of control motor on the mounting rail 5, another
Baffle position limit switch 11 is mounted on a fixed plate on mounting rail 5, and certain distance is kept with origin detection switch 12.
In general, control motor 1 is servo motor or stepper motor.Electricity consumption between the shaft and baffle leading screw 8 of control motor 1
Machine synchronous pulley 2, synchronous belt 3 and baffle screw synchronous belt wheel 4 connect, and in this way according to the rated speed of control motor 1, selection is same
Walk the reduction ratio of band 3 and baffle screw synchronous belt wheel 4, so that it may baffle leading screw 8 be made to obtain suitable rotating speed.
Piston 14 inside cylinder body 20 has several, and piston 14 is centrally mounted in support shaft 13, and the two of support shaft 13
End is fixed on the center of the end cap 6 at cylinder body both ends, and cylinder interior is partitioned into several regions, each region by several pistons 14
Be both provided with air admission hole 9, each air admission hole 9 respectively with it is respective can air control valve 18 connect, can the control terminal of air control valve 18 be connected to
Host controller.To ensure the sealing in each region of cylinder interior, each piston 14 and the junction of support shaft 13 are respectively provided with
There are sealing ring 17, each piston 14 and the junction of cylinder body 10 to be both provided with sealing ring 16.
In use, be provided in host controller with the relevant adjusting parameter of cord width, when cord width changes
Afterwards, host controller starts control motor 1 and rotates, and baffle leading screw 8 is made to rotate, and baffle 7 is moved to origin detection and opens during drive is fixed
12 positions are closed, then invert control motor 1, baffle in surely 7 is moved to the cord width of needs.Meanwhile it is wide according to cord
The ventilation zone of degree selection cylinder interior, opens the air inlet air control valve 18 of ventilation zone, closes the air inlet air control valve in other regions.
In this way, cord is just limited to by two fixed middle baffles 7 in the width of setting, the venthole 15 in the width constantly sprays gas,
One layer of gas-bearing formation is formed between cord and cylinder body so that cord is suspended in cylinder surface, ensures cord to be correctly oriented entrance
Conveying templates do not glance off.
Above-mentioned origin detection switch 12 can also be replaced with linear displacement transducer, at this time after cord width changes,
Baffle 7 need not arrive origin position in fixed, but be converted according to the cord width of the position of current linear displacement transducer and needs
Go out the moving direction and displacement distance of fixed middle baffle 7.But this can increase the cost of whole device.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, the art
Those of ordinary skill the present invention essential scope in, made variations, modifications, additions or substitutions should also belong to this hair
Bright protection domain.
