Craft explanation that,
Pulls a craft: To serves with the certain pulling force to
the fabric latitude, eliminates the fabric in the front processing and
in the dyeing dye printing process because of after nearby the cloth
which comparatively greatly produces to the tensity uneven, the weft
is crooked, the breadth does not wait for the shortcoming.
Setting craft: The fabric under the suitable tensity
condition, heats up needs the temperature and the maintenance certain
time, causes the textile fiber member chain to readjust in the new
position, then cools by the suitable speed, fixedly gets down the
fabric being heated change condition. May eliminate on the
fabric the original wrinkle, but also can prevent again produces the
new fold.
Transmission system: Entire machine mainly has 7 synchro
drives unit (to see system diagram, among, principal chain minute
transmission), 4 circulation air blowers (8 room drying rooms), 2
platoons air blowers.
Specification:
1. about principal chains necessary velocity and
position synchronization, avoid the fabric latitude being slanting.
2. 10 sections of gates control, amplitude
modulation precision control in ±2mm within.
3. temperature control, 8 group PT100 signal input
PLC.
4. tensities controls.
Control system diagram
Control characteristic and plan explanation
The overall system uses the CANopen communication
numeral quantity control, primary control as follows:
1. transmissions partial: Exchange frequency
conversion transmission.
2. control sections: Two HMI (nose airplane
tail), ATV31 frequency changer, 8 group AI, 12 group 40kHz high-speed
counting, CANopen main line.
A 3. principal chains host one from, uses the
encoder signal feedback, PLC each 20ms to carries on the sampling from
the principal chain encoder, carries on the comparison with the host
principal chain encoder signal, according to feeds back the pulse
difference value adjustment from the principal chain speed, the clear
zero host from the pulse value, avoids the accumulative error
producing afterwards, guarantees the host from principal chain speed
synchronization. Is equipped with on HMI from machine the speed
spot moves the revision.
4. besides enters the cloth and the cloth side,
each room drying room also is equipped with a gate control, entire
machine altogether has 10 sections of amplitude modulation, in order
to cause a gate error within the technological requirement,
bidirectional uses the encoder to count the control.
5. drying rooms temperatures directly input PLC by
8 group PT100 simulation quantity (control precision 12), and carries
on the PID adjustment by the PLC programming, on HMI demonstrated each
section of drying rooms temperature and may adjust.
Between 6. various transmissions unit non- tensity
sensor, therefore all is equipped with the speed trimming on HMI.
On 7. 下超 feeds outside the frequency conversion
to meet the brake resistance, negative ultra avoids in feeding in the
process the energy consumption to apply the brake to initiate the
frequency changer frequent breakdown.
8. various units craft speed relations:
V on ultra =V host * (1+K1%)
V 下超 = on V ultra * (1+K2%)
V rolls over the vehicle = V 下超 *
(1+K3%)
V hair brush = on V ultra * (1+K4%)
V cloth = V host * (1+K5%)
V falls/hits = V cloth * (1+K6%)
