Abstract
The utility model discloses a kind of servo glue melting device of injection molding machine, comprise servomotor and gear, feature is that gear comprises housing and is arranged on the planet carrier in housing, planet carrier is provided with multiple planetary gear, planet carrier two end axles is connected on described housing, the inner surface of housing is provided with the internal tooth engaged with planetary gear, servomotor is fixed on housing, the motor shaft inserting line carrier of servomotor is inner, the outer surface of motor shaft is provided with the sun tooth engaged with planetary gear, planet carrier is provided with the power output shaft be connected with melten gel driving shaft, advantage is that motor-driven speed ratio is high, torque loss is little, for same torque requirement, relatively little motor can be used, cost is low and Energy in use is little, transmitting accuracy is high, volume is little.
Description
Technical field
The present invention relates to a kind of glue melting device of injection molding machine, especially relate to a kind of servo glue melting device of injection molding machine.
Background technology
The glue melting device of existing injection molding machine mainly comprises melten gel driving shaft, the oil motor of the driving mechanism that melten gel driving shaft is arranged a normally Direct driver.The shortcoming of this oil motor is that energy consumption is high, precision is low and noise is larger.Therefore, current people gradually adopt servo glue melting device to carry out alternative oil motor, its primary structure connects the rotating shaft of servomotor and melten gel driving shaft by synchronously bringing, but the transmission speed ratio that this structure shortcoming is servomotor is restricted, and torque loss is larger; The injection molding machine of some low speed large torques also uses electric-machine directly-driven, and this can increase the cost of servomotor and the energy consumption of use equally.Also have at present and use servomotor to add reducing gear to realize driving, but the volume of current this structure is larger.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of motor-driven speed ratio is high, torque loss is little, cost is low, volume is little and the servo glue melting device of the injection molding machine that Energy in use is little.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of servo glue melting device of injection molding machine, comprise servomotor and gear, described gear comprises housing and is arranged on the planet carrier in described housing, described planet carrier is provided with multiple planetary gear, described planet carrier two end axles is connected on described housing, the inner surface of described housing is provided with the internal tooth engaged with described planetary gear, described servomotor is fixed on described housing, the planet carrier described in motor shaft insertion of described servomotor is inner, the outer surface of described motor shaft is provided with the sun tooth engaged with described planetary gear, described planet carrier is provided with the power output shaft be connected with melten gel driving shaft.
Described housing comprises shell and end cap, described external tooth is arranged on the inner surface of described shell, the front end of described planet carrier is provided with the first connecting axle, the rear end of described planet carrier is provided with the second connecting axle, described power output shaft is arranged on the first described connecting axle, be provided with clutch shaft bearing between the first described connecting axle and described end cap, between the second described connecting axle and described shell, be provided with the second bearing.
Described end cap is provided with location dome, described injection seat is provided with located cavity, in the located cavity described in described location dome embeds.
Compared with prior art, the utility model has the advantage of that use planetary reducer is as gear, motor-driven speed ratio is high, torque loss is little, and for same torque requirement, can use relatively little motor, cost is low and Energy in use is little; The utility model directly arranges the sun gear that sun tooth is used as engaging with planetary gear on motor shaft, and planetary reducer and motor rigidity are connected as one, and not only transmitting accuracy is high, and reduces the volume of whole glue melting device, reduce further cost.End cap arranges the location dome coordinated with the located cavity on injection seat, on existing injection molding machine, directly can carry out alternative oil motor with driving mechanism of the present utility model, and not need to do any change.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
