1. Check whether you can choose: There may be flashing, flat head, and large-size special-shaped screws during the internship. Grab a handful of non-compliant screws with various special shapes and place them in the hopper. If the automatic locking screw machine can automatically select special-shaped screws during the working process, there will be no jamming, that is, one of the conditions for a good screw machine is met.
2. Check if it can be refilled: when we take the first step, the screw machine automatically selects a special-shaped screw, there must be a gap; if the system can replenish in time, there will be no gap. Up. This is the second condition of a good screw machine.
3. Check if there will be floating teeth: Some manufacturers make all the channels larger in order to make the special-shaped screws pass smoothly. This will make the electric batch nozzle difficult to align with the screw cross grooves, forming the lock screw floating teeth, and increase defective products.
4. Check if the feeding is repeated: sometimes the previous one is not locked, and another screw will be transported when the signal is touched lightly, that is, a double screw.
