> One, step 进电 machine in material measurement
aspect application
1. powdery materials measurements
The screw rod measurement is the commonly used volume type
measurement way, it is revolves 圈数 how many through the screw rod
to achieve the measurement how many, in order to achieve the
measurement size may well distributed increase the measuring accuracy
the goal, requests the screw rod the rotational speed to be possible
to compromise the position localization to be accurate, the use step
进电 machine may simultaneously satisfy these two aspects the
request.
For example the medicinal powder packaging machine measurement
has used the step of 进电 machine control screw rod rotational speed
and the rotation, not only simplified the mechanism, moreover causes
the control to be extremely convenient. In does not overload in
the situation, a step of 进电 machine rotational speed, stops the
position is only decided by the pulse signal frequency and the pulse
number, but the variation of load influence, this the screw rod
measurement which controls with the magnetic clutch is not compared,
has the obvious precision superiority, even more suits to the
proportion change quite big material measurement.
Step 进电 machine and the screw rod use the direct connection
the way, the structure simple, the service is convenient. Is
worth pointing out, if step of 进电 machine overload capacity
generation, when slightly overloads, can appear the quite big noise.
Therefore, after measurement operating mode determination, must
select the bigger acceleration factor, guarantees the step of 进电
machine balance work.
2. sticks the thick body material the measurement
The step of 进电 machine control gear pump also may realize
the precise measurement. The gear pump stuck the thick body
aspect in the transportation to obtain the widespread application, for
example syrup, kidney bean paste, white liquor, fuel oils, ketchup and
so on transportation. At present in mostly uses the piston pump
for these materials measurement aspects, has the adjustment
difficulty, the structure complex, the inconvenient service, the power
loss is big, the measurement does not permit and so on the
shortcoming.
The gear pump measurement is depends on a counter gear to mesh
the rotation measurement, the material is forced through the tooth and
the tooth space from 进料?to deliver the discharge hole.
The power comes from step 进电 machine, the step of 进电
machine rotation position and the speed by the programmable controller
control, the measuring accuracy are higher than the piston pump the
measuring accuracy.
Step 进电 machine is suitable for under the low speed to move,
when the speed speeds up, a step of 进电 machine noise can obviously
enlarge, other economies refer to 标会 the remarkable drop. As
for the rotational speed quite high gear pump that, selects 升 the
structure quite to be good. We in stick on the thick body
packaging machine to start to use are the step of 进电 machine
straight association gear pump structure, finally the sound noise with
difficulty avoids with difficulty, the reliability drops.
Afterwards used the spur gear 升 means, reduced a step of
进电 machine speed, the noise was under the control, the reliability
also had the enhancement, the measuring accuracy obtained the
guarantee.
Second, step 进电 machine in supplies to deliver in the
packing membrane the application
In the system bag, fills, the seal is in a body packaging
machine, the request packing decides the long supplies with the
plastic film localization, regardless of the intermittent supplies or
continuously supply, all may use step 进电 machine to come reliably
to complete.
1. uses in the intermittent type packaging machine
The intermittent type packaging machine use step 进电 machine
supplies the membrane, the reliability to be allowed to obtain the
enhancement. The before packing membrane for delivered selects
the crank link motion gear intermittence 拉带 method, the structure
complex, adjustment difficulty, specially when needed to replace the
product, not only adjustment difficulty, moreover the packing membrane
waste were very many. Uses step 进电 machine with 拉带 the
hoop direct connection 拉带, not only the structure obtained the
simplification, moreover adjusts extremely conveniently, so long as
may realize through the control panel on button, like this both has
saved the control time, and saved the packing material.
In the intermittent type packaging machine, the packing material
for delivers the control to be allowed to use two kind of patterns:
Bag long control pattern and color code control pattern.
The bag long control pattern is suitable to does not bring the
color code the packing membrane, through establishes a step of 进电
machine rotational speed in advance the method realization, brings or
take a coffin the ratio hypothesis through to dial the code switch to
be allowed to realize. The color code pattern equipment has the
photoelectricity switch, the photoelectricity switch examines the
color code the position, when examines the color code, sends out the
controlling switch signal, step 进电 machine after arrives the
signal, stops rotating, after the time delay certain time, then
rotates supplies the membrane, starts once again, guaranteed decides
long according to the color code position supplies the membrane.
2. uses in the continuous-type packaging machine
In the continual labor packaging machine, step 进电 machine is
the continuous rotation, packing membrane by even streamhandling, when
change bag length, only must through dial the code switch to be
allowed to realize.
Third, step 进电 machine horizontally is being sealed the
application
In the continuous-type packaging machine, horizontally seals is
a very important implementing agency, also is in the packaging machine
one of quite complex organizations. Specially regarding the
colored files packing membrane, its seal and the off-position request
is extremely strict, in order to enhance the accuracy which shuts off,
the people have successively developed the eccentric chain wheel
organization, the crank guide rod organization and so on, but these
organizations all have the adjustment extremely to trouble, the
reliable low shortcoming. Creates these shortcomings the main
reason is the technological requirement horizontally seals a turn of
constant speed horizontally to seal with the localization shuts off.
A step of 进电 machine direct drive horizontally seals the
wheel to be allowed to realize speed synchronization. The
continuous-type packaging machine continuously supplies the membrane
for the membrane wheel, horizontally seals when requests the line
speed and the thin film which horizontally seals for speed
synchronization which delivers, in order to avoid appears rends the
situation which the thin film and the thin film piles up, because
horizontally seals a turn of diameter is constant, when change bag
length, needs horizontally to seal a turn of rotational speed through
the change to change, but horizontally seals needs the certain time,
is said horizontally seals turn and the thin film from contacts to
leaves needs the constant time, otherwise the seal quarrels strictly.
Horizontally seals turn every time transfers week-long total
time with the time which horizontally seals needs all is constant,
must satisfy speed synchronization the request, may divide into a step
of 进电 machine week in rotational speed two parts, a part first
satisfies speed synchronization the request, but other idling part
satisfies week total time the request.
