Description
Technical field
The utility model relates to the power set of air-jet loom.
Background technology
In prior art, for air-jet loom provides the power source of the power set of power, be threephase asynchronous.In these power set threephase asynchronous by one-level driving belt by transmission of power to loom driving shaft, owing to passing through driving belt transferring power, therefore the tension force of driving belt is not enough to normal and effective transferring power when relaxing appears in driving belt, cause like this having sliding phenomenon in loom start-up course, significantly increased slippage.
In addition, on loom main shaft, be provided with electromagnetic braking mechanism, for loom, brake.Therefore, the transmission mechanism of these power set and system control aspect all adopt electromagnetic clutch structure.This makes this power set complex structure, and maintenance rate is high, and trouble point is many.Consumed energy, is the operation of Clutch Control during machine down on the one hand, and motor is still worked, and work is frequent, and fault rate is relatively high, takes normal maintenance.On the other hand, machining cost, raw material loss are large, difficulty of processing strengthens relatively, aspect control sensitivity, be not very desirable, and regulation and repairment is more complicated.Further, clutch can produce spark in frequent operation, the yarn fibers in workshop of easily igniting and cause fire.Especially, slow in reacting while shutting down by Clutch Control Air-Jet Spinning loom, reduce the quality of woven product.Also have by control device transforms the mode of connection of threephase asynchronous between delta connection and star connection, thereby on threephase asynchronous, obtain high pulling torque output, but this mode still forces machine operation and realizes brake force output in destructive mode.
These reasons cause existing jet type loom to have the problem that transmission efficiency is low, insensitivity is poor just.
Utility model content
Technical problem to be solved in the utility model has just been to provide a kind of power set of air-jet loom, improves transmission efficiency and insensitivity.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of power set of air-jet loom, comprise servomotor, described servomotor is installed a main driven wheel on output shaft, described main driven wheel while and travelling gear and the opening travelling gear engaged transmission of beating up, described opening travelling gear is installed on opening driving gearshaft, on described opening driving gearshaft, electricity loss brake is installed, the described travelling gear that beats up is installed on power transmission shaft, Conjugate Cam In Beating-up Mechanism is also installed on described power transmission shaft, described servomotor drives through main driven wheel beat up travelling gear and the rotation of opening travelling gear simultaneously, opening travelling gear drives shedding mechanism motion to realize loom harness motion, the travelling gear that beats up is synchronizeed and is rotated with power transmission shaft, power transmission shaft drives Conjugate Cam In Beating-up Mechanism to rotate again, Conjugate Cam In Beating-up Mechanism drives beat up balance staff and roller swing thereof.
Preferably, described electricity loss brake comprises yoke, magnet exciting coil, spring, brake disc, armature and spline housing, described opening driving gearshaft connects by spline housing and brake disc, during energising, between yoke, magnet exciting coil, armature, by electromagnetic action, armature and brake disc are departed from, during brake power-off, spring applies pressure to armature to be forced between brake disc and armature and produces moment of friction.
Preferably, described main driven wheel, beat up travelling gear and opening travelling gear are straight spur gear.
The technical solution of the utility model, the gear transmission structure that utilize main driven wheel, beat up travelling gear and opening travelling gear forms improves transmission efficiency, and simplified structure, makes to adjust and maintenance becomes convenient; In addition; by servomotor, produce power; can utilize the high pulling torque output characteristic of servomotor itself; while realizing air-jet loom startup, in the short time, reach tightening weft speed; utilize the speed controllability of servomotor, easily change loom rotating speed, the braking function of recycling servomotor itself; realize the functions such as shutdown braking, location shutdown of loom, while utilizing electricity loss brake can prevent that loom from having a power failure suddenly because inertia remains in operation.Thereby, finally improved by the way transmission efficiency and insensitivity.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of power set of air-jet loom, comprise servomotor 1, described servomotor 1 is installed a main driven wheel 2 on output shaft, simultaneously and travelling gear 3 and opening travelling gear 4 engaged transmission of beating up, described main driven wheel, beat up travelling gear and opening travelling gear are straight spur gear to described main driven wheel 2.Described opening travelling gear 4 is installed on opening driving gearshaft, on described opening driving gearshaft, electricity loss brake 7 is installed, the described travelling gear 3 that beats up is installed on power transmission shaft, Conjugate Cam In Beating-up Mechanism 5 is also installed on described power transmission shaft, described servomotor 1 drives through main driven wheel 2 beat up travelling gear 3 and 4 rotations of opening travelling gear simultaneously, opening travelling gear 4 drives shedding mechanism motion to realize loom harness motion, the travelling gear 3 that beats up is synchronizeed and is rotated with power transmission shaft, power transmission shaft drives Conjugate Cam In Beating-up Mechanism 5 to rotate again, Conjugate Cam In Beating-up Mechanism 5 drives beat up balance staff and roller 6 swings thereof.
On beating-up mechanism, be connected with encoder, servomotor 1 and encoder are electrically connected to controller, feed back to controller after responding to the angle signal of loom, then send instructions and control the action of servomotor after being processed according to signal by controller by encoder.
During work, servomotor 1 is under the control of controller, drive main driven wheel 2 rotations, main driven wheel 2 drives beat up travelling gear 3 and 4 rotations of opening travelling gear simultaneously, by the travelling gear 3 that beats up, drives Conjugate Cam In Beating-up Mechanism 5 rotations, and Conjugate Cam In Beating-up Mechanism 5 drives beat up balance staff and roller 6 (other parts on these looms) swing thereof, realize beating-up, 4 rotations of opening travelling gear, drive shedding mechanism motion, realize loom harness motion.
The effect of electricity loss brake 7 is exactly that loom can be braked in time, prevents that loom is because inertia remains in operation when loom has a power failure suddenly.Concrete, electricity loss brake comprises yoke, magnet exciting coil, spring, brake disc, armature and spline housing, described opening driving gearshaft connects by spline housing and brake disc.
When the magnet exciting coil of electricity loss brake 7 is connected rated voltage (DC), electromagnetic force adhesive armature, make armature and brake disc depart from (release), at this moment opening driving gearshaft runs well with brake disc or starts, when transmission system separation or power-off, electricity loss brake is simultaneously power-off also, and now spring applies pressure to armature, force between brake disc and armature and ring flange and produce moment of friction, make the quick stall of opening driving gearshaft.
