Dynamic ratio of precision is high by synchronous belt direct pull, and knife cutting in angle is more acurrate.
In above-mentioned angle knife driving mechanism, the motor is fixed in back plate, the shaft of the motor and the screw rod
Between pass through toothed belt transmission connect.And the movement of slide angle tool apron is directly converted by the movement of screw rod, kinematic accuracy is than logical
It crosses synchronous belt direct pull and wants high, and the synchronous strip length between screw rod and motor is shorter, influence is smaller, therefore, the cutting of angle knife
It is relatively accurate.
In above-mentioned angle knife driving mechanism, this driving mechanism further includes for detecting whether slide angle tool apron returns to just
The detecting element of beginning position.Detecting element can be position sensor and plate detecting sensor, can accurately detect slide angle knife
Seat whether return in place.
Compared with prior art, this angle knife driving mechanism has the advantage that
1, the movement of slide angle tool apron is driven by motor direct-drive screw rod, kinematic accuracy is higher than synchronous belt, and angle knife is cut
It cuts more acurrate.
2, since slide angle tool apron is fixed on two sliding blocks, two sliding blocks are connected on two corresponding sliding rails,
So that slide angle tool apron is highly stable, shaking there's almost no, angle knife cutting accuracy is very accurate.
