Abstract
Belonging to the technical field of textile machinery, the utility model relates to a stable-transmitting electric doffer, which is used to resolve the problem that the failure rate of the transmission device of the doffer is high. The electric doffer comprises an electric motor and a transmission device; wherein, the electric motor drives a speed changer in the transmission device to rotate; the output shaft of the speed changer drives an eccentric wheel to rotate; the eccentric wheel is hinged with one end of an oscillating rod, the other end of the oscillating rod is hinged with one end of a short rocker, the other end of the short rocker is hinged with one end of a long rocker, the other end of the long rocker is hinged with one end of a bent link rod, the other end of the bent link rod is hinged with a driving gear which is engaged with two driven gears, and the driven gears drive roller twisters. The electric doffer changes the chain transmission of the transmission device of the doffer into the gear transmission, moreover, the bent link rod is designed at an appropriate bend angle, and as a result, the improvements obviously reduce impact force and improve movement stability. The experiment indicates that the stable-transmitting electric doffer can reduce the failure rate of the doffer by seventy percent, and the service lives of parts such as gears are prolonged from one month to one year.
Description
Technical field
The utility model relates to a kind of textile machine, and the electro-automatic doffer especially for spun yarn doffs belongs to the Weaving device technical field.
Background technology
The spinning workshop doffing operation of textile mills adopts doffer more, and at present, the kind of electro-automatic doffer is a lot, but its transmission structures is basic identical.Referring to Fig. 2, this is a kind of FU911-180 type electro-automatic doffer schematic diagram commonly used.As seen from the figure, comprise two sprocket wheels 12 that drive by chain 11 in the transmission device at this doffer conduit position, the transmission process of whole transmission device is: motor is passed to speed changer 1 with power, after slowing down, driving eccentric wheel 3 by transmission output shaft rotates, eccentric wheel drives swing arm 4 motions, swing arm drives short rocker arm| 5 motions, short rocker arm| drives long rocking arm 6 motions, long rocking arm drives curved rod 7 motions, the reciprocating motion of curved rod chain drive-belt, and chain drives sprocket wheel and back and forth rotates, sprocket wheel drives the motion of rubbing roller device, and ring bobbin can be derived smoothly.This kind equipment finds that in the back of coming into operation transmission device chain releasing, carrier bar, sleeve, roller easily takes place the fault that impact failure and chain and curved rod are broken easily takes place, and has had a strong impact on doffer's normal running.Through scrutinizing analysis, think that there is structural unreasonable place in former design: transmit motion and power in the common mechanical because the chain transmission is mainly used in, usually (v≤20m/s) use down should not use in the big and reverse rapidly transmission of load change the medium speed.And the transmission device on the doffer belongs to back and forth movement rapidly, its transmission speed has reached 30m/s, therefore in actual motion, the dynamic loading of transmission is excessive, impacts thereupon and strengthens, cause transmission not steady, chain sprocket wearing and tearing aggravation adds that teeth number of sprocket is too small, and does not have tensioning apparatus, therefore very easily cause chain to split away off, can not keep its regular event from sprocket wheel.
Summary of the invention
The utility model is used to overcome the defective of above-mentioned prior art and a kind of stable transmission electro-automatic doffer steadily soft, that fault rate is low that moves is provided.
The alleged problem of the utility model is solved by following technical scheme:
A kind of stable transmission electro-automatic doffer, comprise motor and transmission device in the formation, speed changer in the electric motor drives rotates, its special feature is, in described transmission device, the output shaft of speed changer 2 drives eccentric wheel 3 rotations, eccentric wheel and swing arm 4 one ends are hinged, the hinged driving gear 8 of an end, the curved rod other end, driving gear and two driven gears 9,10 of an end of the hinged short rocker arm| 5 of the swing arm other end, an end of the hinged long rocking arm 6 of the short rocker arm| other end, the hinged curved rod 7 of the long rocking arm other end mesh driven gear drive rubbing roller device.
Above-mentioned stable transmission electro-automatic doffer, the described driving gear number of teeth are that 48, two driven gear numbers of teeth are respectively 24,15.
Above-mentioned stable transmission electro-automatic doffer, the angle β of described curved rod left part driving part 7-1 and its middle part straight-bar position 7-2 is 40 degree.
The utility model improves at the drawback that existing electro-automatic doffer transmission device easily breaks down, it changes the chain transmission of driven end in the transmission device into gear drive, and designed suitable angle of bend for curved rod, drive driving gear by curved rod and rotate, will move by driving gear again and pass to two driven gears respectively.Become the circular curve motion through this movement locus that improves curved rod by rectilinear motion, obviously reduced impulsive force, robust motion is improved.The number of teeth difference of two driven gears, this design makes transmission produce speed difference, cause two rubbing roller device speed differences, make ring bobbin pass through more smoothly, in addition, efficient height, the life-span that gear drive itself had is long, working stability is reliable etc., and advantage is embodied herein.Test shows that improved doffer fault rate has reduced by 70%, and major parts such as gear extended to 1 year by original one month service life.The utility model efficient height, the life-span is long, can reduce repair time and supplies consumption, thereby reduce production costs, and enhances productivity.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the doffer structural representation before improving.
The label of each parts is expressed as follows among the figure: 1. motor; 2. speed changer; 3. eccentric wheel; 4. swing arm; 5. short rocker arm|; 6. long rocking arm; 7. curved rod; 7-1. curved rod left part driving part; 7-2. straight-bar position, curved rod middle part; 8. driving gear; 9,10. driven gear; 11. chain; 12. sprocket wheel.
The specific embodiment
Referring to Fig. 1, comprise motor 1 and transmission device in the formation of the present utility model, the speed changer of electric motor drives rotates, the transmission device transmission process is as follows: output shaft drive eccentric wheel 3 rotations of speed changer 2, eccentric wheel drive swing arm 4 move, swing arm drive short rocker arm| 5 moves, the long rocking arm 6 of short rocker arm| drive moves, long rocking arm drive curved rod 7 moves, curved rod driving driving gear 8 back and forth rotates, two driven gears 9,10 of driving gear drive back and forth rotate, and driven gear drive rubbing roller device moves.For reduce the driving resistance of curved rod as far as possible, the utility model design curved rod left part driving part 7-1 and its middle part straight-bar position 7-2 angle β are that 40 degree are advisable.In the gear drive that the utility model transmission device end is adopted, the driving gear modulus is 1.5, and the number of teeth 48, the number of teeth of driven gear 9 are 24, and the number of teeth of driven gear 10 is 15.This design can make centre-to-centre spacing keep consistent with former chain drive, and because the number of teeth difference of driven gear makes transmission produce speed difference, causes two rubbing roller device speed differences, makes ring bobbin pass through more smoothly, finishes intubate, thereby has improved production efficiency.
