Understanding the Elements and Capabilities of a Pneumatic Foot Lifter
Strain Swap
The strain change is a vital element that detects the presence of compressed air within the system. When the strain reaches a predetermined degree, the change journeys, activating the solenoid valve.
Solenoid Valve
The solenoid valve is an electromagnetically operated valve that controls the circulate of compressed air. When activated, the solenoid valve opens, permitting air to enter the air cylinder.
Air Cylinder
The air cylinder is a mechanical actuator that converts the compressed air into linear movement. As compressed air enters the cylinder, the piston strikes, elevating or reducing the foot lifter.
Foot Lifter
The foot lifter is the bodily mechanism that lifts the presser foot of the overlock machine. It’s linked to the air cylinder and strikes in response to the air strain.
Foot Pedal
The foot pedal is the consumer interface that triggers the foot lifter. When the operator presses the foot pedal, it prompts the strain change, initiating the sequence of occasions that increase the presser foot.
Adjustment Screw
The adjustment screw permits the operator to fine-tune the peak to which the foot lifter raises the presser foot. This ensures exact adjustment for various cloth thicknesses and stitching methods.
