The working principle of the mechanical type overload protection arrangement of the pusher in the utility model embodiment is as follows:
During pusher normal operation, the input of motor passes to drive plate 109 by gear train, under the effect of Compress Spring 107, projection 108a engagement on groove on drive plate 109 and overload separation device 108, with drive plate 109 rotations, the polygon shaft 108b of overload separation device 108 and the axis hole 106b of output shaft 106 are in transmission connection, overload separation device 108 drives output shaft 106 rotations, thereby drive screw rod 105 rotations, the guide groove 104a on pushing piston 104 coordinates and axially moves along screw rod 105 with the guide pillar 103b in barrel 103; Pushing piston 104 advance resistances pass to Compress Spring 107 by screw rod 105 and output shaft 106.When pushing piston 104 advance resistances are greater than Compress Spring 107 rated tension; pushing piston 104 halts; screw rod 105 axially retreats and promotes recessed tooth 106d and the engagement of the double wedge 102c on lower casing 102 of output shaft 106 input ends; output shaft 106 stops operating; overload separation device 108 stops operating under the effect of output shaft 106; at this moment overload separation device 108 reverse compression Compress Springs 107; from engagement, become releasing engagement with drive plate 109; discharge the torsion of motor input and send tap-tap, thereby playing the effect of overload protection.
When the thread damage of screw rod 105 or pushing piston 104 or other reason cause screw rod 105 and pushing piston 104 in stuck or be fixedly connected with state; while causing screw rod 105 operation torsion to be greater than the torsion of output shaft 106 outputs; overload separation device 108 stops operating under the effect of output shaft 106; at this moment overload separation device 108 reverse compression springs 107; from engagement, become releasing engagement with drive plate 109; discharge the torsion of motor input and send tap-tap, the protection under this state is not subject to motor positive and reverse return to affecting.
When reverse torsion is inputted in motor counterrotating, pushing piston 104 axially oppositely retreats along screw rod 105, when pushing piston 104 retreats into screw rod 105 end, buckle 106e spins off from draw-in groove 105b, and pushing piston 104 can drive screw rod 105 separated with output shaft 106 voluntarily.
As can be seen here; mechanical type overload protection arrangement in the utility model embodiment is owing to having adopted said structure; can be from axially, radially both direction guarantees that pushing piston 104, screw rod 105 effectively discharge load under overload situations; guarantee machine and operator's safety, and increased mechanical working life.And mechanical type overload protection arrangement has simple in structure, reliable, easy to operate, with low cost advantage.
In another embodiment of the utility model, provide a kind of hand electric biscuit moulding press, it comprises the mechanical type overload protection arrangement in above-described embodiment.Hand electric biscuit moulding press, owing to having adopted mechanical type overload protection arrangement, can effectively protect machine to avoid damaging, and extends machine service life.
The above embodiment has only expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
