The intermittent type rotating mechanism is characterized by also comprising a groove wheel and a rotating arm, wherein the groove wheel is connected onto the main shaft by a button; a plurality of radial grooves which are uniformly distributed on the circumference are arranged on the groove wheel; the rotating arm is connected onto an output shaft of the speed reducing machine by a button and is connected with a pushing rod which is matched with the radial grooves. The intermittent type rotating mechanism has the advantages of fewer parts, simple structure and low energy consumption and guarantees accurate control on the rotating angle for each time.

Description

A kind of intermittent type rotating machinery

Technical field

The utility model relates to a kind of intermittent type rotating machinery.

Background technique

Traditional rotating machinery mostly is continuous rotation, but (as feeding at intermittence) need to be used intermittent type rotating machinery under some operating mode, and current intermittent type rotating machinery component are more, structure is comparatively complicated, and energy consumption is higher.

Summary of the invention

The purpose of this utility model is for prior art above shortcomings, and a kind of intermittent type rotating machinery is provided, and it has advantages of, and component are less, simple in structure, energy consumption is low.

For achieving the above object, intermittent type rotating machinery of the present utility model, comprise frame, motor, speed reducer, by bearing support and bearing, be located at the main shaft in frame, the input shaft of motor and speed reducer is connected, and characterized by further comprising sheave, cursor, sheave by binding on main shaft, sheave is provided with several radial grooves uniform on circumference, cursor on the output shaft of speed reducer, is associated with push rod by binding on cursor, and push rod matches with radial groove.

Working principle of the present utility model is: motor, speed reducer drive cursor to rotate, the every rotation of cursor one week, on LAP therein, push rod enters a radial groove on sheave, promote after sheave turns an angle to exit from this radial groove, so circulation, the push rod on cursor can promote sheave and main shaft rotation in intermittent type ground, realizes the object of expection; Than prior art, the utlity model has the advantage that component are less, simple in structure, energy consumption is low;

As further improvement of the utility model, in the front center of cursor, be provided with the slot to make way radially corresponding with sheave, at the front end of cursor, be also provided with axial draw-in groove, described push rod is coupled on cursor through draw-in groove the nut by two ends; Can realize the producing balanced forces of cursor and sheave;

As further improvement of the utility model, the push rod middle part in slot to make way is provided with step, on the push rod of step both sides, all by spacer, is provided with rolling bearing; By rolling bearing, contact with sheave, can reduce wearing and tearing;

As further improvement of the utility model, on main shaft, by key, be also associated with eccentric Brake drum, one brake strap is around on eccentric Brake drum, the two ends of brake strap are positioned at the both sides of eccentric Brake drum and connect firmly with pulling seat separately respectively, each pulling seat is fixed on screw rod separately, and the lower end of every screw rod, all through frame, is equipped with adjusting nut on the screw rod below frame, on the screw rod above frame, be equipped with baffle plate, on every screw rod between baffle plate and frame, all cover has Compress Spring; When push rod is separated with sheave, brake strap carries out friction catch to eccentric Brake drum, can accurately locate main shaft, guarantees the accurate control of each rotation angle;

In sum, the utlity model has the advantage that component are less, simple in structure, energy consumption is low, and guarantee the accurate control of each rotation angle.
