Description
Technical field:
The present invention relates to a kind of mechanical transmission mechanism, especially a kind of transmission mechanism used in tricot machine loop-forming element
Background technique
It is by the result of the interactions such as groove pin, needle core, knocking-over bit, sinker, sley bar in tricot machine knitting cycle.Slot
Needle, needle core, knocking-over bit, sinker, sley bar etc. are moved according to each required working trajectory respectively, realize knitting cycle, and this at
Circle needs transmission mechanism to drive.
The transmission mechanism of tricot machine is based on main shaft, and by cam, eccentric ratio, the various transmission devices such as gear make
Each loop-forming element on machine it is anticipated that motion profile movement, realize the lopping work of machine.Existing mainstream coiler
The transmission mechanism of part has: cam link transmission mechanism, eccentric ratio transmission mechanism.
Cam link transmission mechanism, between cam and driven member is line or point contact, and pressure is big, and easy to wear, noise is big,
Inertia is big, and transmission speed is low, and there is very big impact during exercise, greatly reduces the establishment speed and stabilization of machine
Property, can not be applicable in high speed weaves, and fabricates difficulty, and accuracy is low.
The kinematic pair of eccentric ratio transmission mechanism is revolute pair, and two bars of phase hinge are face contacts, and pressure is small, parts mill
Damage small, but when rod piece is more, since there are gaps between the contact surface of two bars, accumulated error is with regard to larger.And setting between connecting rod
Meter and equilibrium problem are more complex.
These movement parts require to be immersed in lubricating oil.A large amount of lubricating oil generates oil leak situation sometimes, not only causes to knit
Object has greasy dirt, and workshop also has greasy dirt.Board running part is because friction generates loss, and the service life of part is short, and zero
Part is since friction temperature raising causes into collar member needle needle gage deviation, therefore board needs work in isoperibol.
Most of tricot machine transmission mechanism all uses eccentric drive mechanism currently on the market, but eccentric drive mechanism
Not convenient for safeguarding, transmission speed is slow in the presence of structure is complicated, motional inertia is big, the response time is long, does not adapt to nowadays tricot machine intelligence
Change development.It is especially now arranged in the period of order small lot multi items, the board of usual same mechanical structure is only capable of producing one kind
The fabric of style.The board long period that so there is some mannerisms is in shutdown status, and to weaving, producer is brought
Biggish economic pressures.
Summary of the invention:
The driver has been invented in order to solve above-mentioned technical problem by calculating for a long time, simulation, test etc.
Structure.It can be accurately controlled speed, displacement and power, small with inertia, response is fast, low noise and long-life characteristic, structure
Simply, easy to maintain, be conducive to improve entire transmission mechanism work system rapidity.
A kind of the technical solution adopted by the present invention to solve the technical problems: transmission mechanism packet of tricot machine loop-forming element
It includes: needle core transmission mechanism, groove pin transmission mechanism, knocking-over bit transmission mechanism, sley bar transmission mechanism, sinker actuation mechanism, pressure yarn
Transmission mechanism.It is characterized by: the needle core transmission mechanism, groove pin transmission mechanism, knocking-over bar transmission mechanism, sley bar driver
Structure, sinker actuation mechanism, pressure yarn transmission mechanism are made of components such as respective balance staff, swing arm, connecting rods, and the transmission mechanism is equal
Link rotatable is driven by servo electric jar.
Further, in a kind of transmission mechanism of tricot machine loop-forming element, the swing arm upper end of the transmission mechanism
Each self installation needle core, groove pin, knocking-over bar, swing arm lower end are connected with balance staff and connecting rod respectively, the other end and servo-electric of connecting rod
Cylinder connection.
Further, the transmission mechanism and servo electric jar are installed in cabinet.
Further, the motion profile of each transmission mechanism can be set on demand.For example, working as some patterns of fabric process requirement works
When making the more machine of line, the stroke that groove pin is swung can be increased to desirable value.When some patterns of fabric process requirements work
The stroke that groove pin is swung can be reduced to desirable value when line less machine, so as to improve starting up speed.When some are knitted
The different lopping of object flower pattern process requirement work line number when, cooperate then groove pin can be run to height with sley bar height, most
Reach required lopping work line number afterwards to weave, the fabric of a variety of styles can be woven.And it can be selected in this mechanism
Select addition schlagblech mechanism, Weft laying mechanism etc..Can achieve a machine can weave the fabric of a variety of styles, meet small quantities of
Measure the market demand of more orders.
The beneficial effects of the present invention are: a kind of transmission mechanism of tricot machine loop-forming element is whole using servo electric jar drive
A transmission mechanism, the mechanism can be accurately controlled speed, displacement and power, have that inertia is small, response is fast, low noise and long-life
Characteristic.In daily maintenance, avoid because lubricating oil need to be used using cam link transmission mechanism and eccentric ratio transmission mechanism
And bring oily pollution, oily pollution are easy to make element friction surface to generate injury, influence element service life, it is serious cause be
Failure of uniting or shutdown.In whole system operating, when starting and suspending machine, revolving speed is also at the uniform velocity to rise or decline, and is avoided
Rapidly start or suspend greatly frictional force produced by machine to damage actuated element, this transmission mechanism rotation is smooth, used
Measure it is small, transmission it is more reliable.
