Blow-molded AutomaticLocking screw machineGenerally suitable for M1-M6 screws, with lengths less than 25, and the total screw length L must be greater than 1.3 times the screw head diameter D; otherwise, a side-over phenomenon may occur in the feeding tube, preventing normal delivery.

Automatic Screw Feeding Machine's Screw Detection: The screws are distributed into the pipes through a feeder, while the screws fall into the pipes, sensors detect them to ensure that one screw falls into each pipe. Once four pipes are filled, the feeding machine sends a pulse signal to the PLC. The PLC reads this signal before executing the blowing and screw locking actions. Otherwise, the machine will alarm and wait for the fault to be resolved.
