ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to an improvement for circular knitting machine and particularly a press ring adjustment structure for coupling with a steel ring set used in a circular knitting machine.
It is commonly known that when the transmission mechanism (shown in
FIG. 1
) of a conventional circular knitting machine does not run smoothly or becomes unstable in operation, or abnormal vibration or noise occurred during the circular knitting machine operation, the problems mainly result from the wearing steel ring set
3
(i.e. there are gaps between the steel ring
3
and the frame
1
, lower transmission gear
2
, and press ring
4
). To remedy the problems, operator has to disassemble a lower diamond ring (not shown in the figure) and the needle drum seat
5
, then unfasten an adjustment element
14
, and remove the press ring
4
and the existing washer
44
. Then the operator has to replace a thinner new washer
44
on a bulged ring
12
located in the frame
1
, screw the press ring
4
over the bulged ring
12
to narrow the interval between the recess
45
and
15
of the press ring
4
and bulged ring
12
whereby to eliminate the gap between the steel ring set
3
and the recess
22
of the lower transmission gear
2
. After all this has been done, the spindle (not shown in the figure) may drive the lower transmission gear
2
and needle drum seat
5
to operate smoothly without generating vibration or noise.
The foregoing adjustment needs to disassemble a lot of components for replacing the washer
44
and to assemble the components again. It takes a lot of time and work.
Moreover, the press ring
4
, frame
1
and lower transmission gear
2
also need adjustments at the same time when adjusting the steel ring set
3
to an optimal operative condition and to enable the lower transmission gear
2
running at a normal state. This is also a tedious and time-consuming process.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages, it is therefore an object of this invention to provide a novel adjustment method that does not need to disassemble any component so that the steel ring set may be adjusted rapidly to restore the circular knitting machine to normal operation.
Another object of this invention is to provide an adjustment structure that needs only adjusting the press ring to achieve the result desired. It thus may save a lot of work and time.
In one aspect of this invention, the press ring is located above a bulged ring of the frame. After unfastening an adjustment element disposed in the frame, the pressing force of the press ring on the steel ring set will be released. Then the original washer may be removed for replacing a thinner washer between the press ring and bulged ring. Fasten the adjustment element again, a collar section of the press ring will press the steel ring set again so that there will be no gap between the steel ring set and the frame, lower transmission gear and press ring. Then the spindle may drive the lower transmission gear to enable the circular knitting machine function normally.
