Abstract
The utility model discloses a heat transfer printing machine rotary table driving mechanism which comprises a motor for driving a rotary table to rotate. The heat transfer printing machine rotary table driving mechanism is characterized in that the motor drives a worm-gear reducer to rotate through a torsion limiter and a driven shaft of the worm-gear reducer is connected with the rotary table. According to the heat transfer printing machine rotary table driving mechanism, when the rotary table is in overload or in mechanical failure and required torsion exceeds a set value, the torsion limiter limits torsion force transmitted by a transmission system in a sliding mode, when the overload condition disappears, linkage is automatically restored, and therefore mechanical damage is prevented, machine stopping losses are avoided, and working efficiency is improved.
Description
Technical field
The utility model relates to a kind of heat transfer machine, relates in particular to a kind of heat transfer machine turntable driving machine structure.
Background technology
At present, heat transfer machine is when work, and the rotation of turntable is controlled electric motor starting usually by Artificial Control by artificial floor push, drives turntable and rotates.Turntable often turns a station, just need to start a motor, so electric motor starting is frequent.When overload or mechanical breakdown occurring, turntable is stuck in the time of can't rotating, and operating personnel still continue starter motor and carry out work in the situation that can't learn, often can cause transmission system or other mechanical parts to damage, and cause systemic breakdown.Often can cause the turntable stall owing to little fault occurring, thereby the fault rate that the motor of frequent starting causes is increased, affect operating efficiency.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of heat transfer machine turntable driving machine structure, when turntable overload or mechanical breakdown, can the limiting drive train system torsion of institute's transmission, prevent mechanical failure, avoid shutting down, increase work efficiency.
For solving the problems of the technologies described above, the utility model provides a kind of heat transfer machine turntable driving machine structure, comprises the motor that drives the turntable rotation, it is characterized in that, described motor drives a worm-gear speed reducer by a torque force limiting device and rotates, and the driven shaft of described worm-gear speed reducer is connected with turntable.
The driving shaft of described worm-gear speed reducer connects a driven pulley by described torque force limiting device, and a driving wheel is set on the output shaft of described motor, and described driving wheel and driven pulley are in transmission connection by band.
Described reductor driven shaft is vertical with driving shaft, and described driven shaft is connected with described turntable.
The output shaft of described motor is parallel with the driving shaft of reductor.
The beneficial effect that the utility model reaches:
Heat transfer machine turntable driving machine structure of the present utility model; when turntable overload or mechanical breakdown; when required torque surpasses setting value; torque force limiting device is with the torsion of the form limiting drive train system institute transmission of skidding; after disappearing, the overload situation recovers voluntarily to connect; so just prevent mechanical failure, avoided shutdown loss, improved operating efficiency.
Description of drawings
Fig. 1 is heat transfer machine turntable driving machine structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, heat transfer machine turntable 1 is a disk that can rotate around the center of circle, and 4 stations are set on turntable 1, is respectively material level, detects station, hot transfer printing position, lower material level, and turntable 1 once rotates 90 degree, and workpiece is transported to next station by current station.Turntable 1 drives automatic rotating by driving mechanism, driving mechanism comprises motor 2, by the worm-gear speed reducer 3 that motor 2 drives, the output shaft of motor 2 is parallel with the driving shaft of reductor 3, and by band transmission 4 connections, reductor 3 driven shafts are vertical with driving shaft, and driven shaft is connected with turntable 1.When motor 2 rotates, drive reductor 3 driving shafts by the band transmission and rotate, by the Worm Wheel System in reductor 3, driven shaft is rotated, drive turntable 1 and rotate.
One driving wheel 21 is set on the output shaft of motor 2, connects a driven pulley 31 by a torque force limiting device 5 on the driving shaft of reductor 3, driving wheel 21 is in transmission connection by band with driven pulley 31.Carry out overload protection by torque force limiting device 5; when causing required torque to surpass setting value when overload or mechanical breakdown; torque force limiting device is with the torsion of the form limiting drive train system institute transmission of skidding; after disappearing, the overload situation recovers voluntarily to connect; so just prevent mechanical failure, avoided shutdown loss.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection domain of the present utility model.
