Said Control Component comprises second support, second motor, cam, second release block and second back-moving spring; Said second motor, second release block are located on second support; Second motor output shaft is connected with cam; Cam is through the action of second release block control press unit, and second release block is provided with second back-moving spring.
Compared with prior art, the beneficial effect of the utility model is,
1. press unit discharges automatically, realizes automated production easily;
2. squeeze from the gravity of establishing weight on the dependence press unit, squeeze force is constant;
3. press unit is led by guide rail, can run-off the straight;
4. all need not manual intervention in squeezing beginning and the pressing process, time saving and energy saving.
