Abstract
The utility model proposes a kind of drive unit of button-sewing machine, comprise frame, drive unit frame being arranged upper punch axle and drive upper punch axle to move up and down, it is characterized in that: described drive unit comprises the motor, planetary gear speed reducing mechanism and the output shaft that connect successively, described planetary gear speed reducing mechanism comprises the sun gear, gear ring, the planetary gear that are connected to motor output end and is connected to output shaft and planetary planet carrier, and described planetary gear is between sun gear and gear ring and be at least three settings; The drive unit of a kind of button-sewing machine upper punch axle of the present utility model, can slow down the load of output shaft, have more stable structure.
Description
Technical field
The utility model relates to a kind of button-sewing machine, particularly relates to the drive unit of button-sewing machine.
Background technology
Button-sewing machine is in the process of bookbinding, drive upper punch axle to carry out lifting activity by motor and with the coordinating of lower punch die, complete the bookbinding of button, drive unit of the prior art comprises drive motors, reductor, the output of reductor is connected to output shaft, output shaft is connected with moving runner, on moving runner, eccentric setting has the connecting rod being connected to upper punch axle, some button-sewing machines directly carry out replacement output shaft and eccentric wheel structure with bent axle, the upper punch axle that eccentric wheel is connected to upper punch axle makes it move up and down, but in the process of motion, because eccentric wheel and low punch are in linkage status, in the process of upper punch axle lifting, under the effect of inertia, eccentric wheel can increase the radial load of output shaft, such structure is after long-time running, drive unit is stable not, output shaft is beated because unbalance stress produces radial clearance.
Utility model content
Based on the problems referred to above, the utility model object is the drive unit providing a kind of button-sewing machine upper punch axle, can slow down the load of output shaft, have more stable structure.
For above problem, provide following technical scheme: a kind of drive unit of button-sewing machine, comprise frame, drive unit frame being arranged upper punch axle and drive upper punch axle to move up and down, it is characterized in that: described drive unit comprises the motor, planetary gear speed reducing mechanism and the output shaft that connect successively, described planetary gear speed reducing mechanism comprises the sun gear, gear ring, the planetary gear that are connected to motor output end and is connected to output shaft and planetary planet carrier, and described planetary gear is between sun gear and gear ring and be at least three settings.
The utility model is also set to further, and described planetary gear speed reducing mechanism also includes housing, and described housing is fixed in frame.
The utility model is also set to further, and described output shaft and motor output end are each passed through housing and are connected to planet carrier and sun gear, are provided with bearing between output shaft and housing.
The beneficial effects of the utility model, the rotating speed of motor output end can be reduced by planetary gear speed reducing mechanism, be convenient to drive upper punch axle, but main points of the present invention are, by at least three planetary gears and the coordinating of sun gear being connected to motor output shaft, even if the moving runner of output shaft end and connecting rod have certain inertia in the process of motion, gear ring, planetary gear and sun gear can be stable carry out coordinating of gears meshing, form more stable fit structure, make motor output end and output shaft all have certain stability.
