Product Overview

The motor-driven pusher feeder is an automatic push-feeding machine powered by a gear motor (or servo motor). Through a reduction transmission mechanism, the motor drives the pusher plate in a reciprocating linear motion, pushing pre-sorted workpieces from the hopper or vibratory bowl feeder in rows smoothly to the processing station or conveying track. It is a key secondary feeding device that links bulk loading with machining and assembly on automated production lines.

Compared with pneumatic pusher feeders, the motor-driven pusher feeder offers precisely controllable stroke and cycle, smooth and quiet operation, and requires no compressed air supply. It is especially suitable for continuous production requiring high positioning accuracy and stable feeding rhythm. Often working in line with electric vibratory bowl feeders, it is widely used for automatic feeding of fasteners, stamped metal parts, and injection-molded parts.

⚙️ 1. Drive System Specifications

Parameter	Typical Range / Description
Drive type	Gear motor + crank-linkage / ball screw / synchronous belt transmission; servo motor drive optional
Rated voltage	Standard 220V; 110V / 380V available on request
Motor power	Small machines approx. 90W–120W; medium machines 200W–400W; large machines up to 750W
Pushing frequency	Typically 20–60 cycles/min, steplessly adjustable via VFD or servo control
Pushing stroke	30–300 mm, mechanically adjustable; servo models allow programmable stroke and position
Transmission protection	Fully enclosed transmission with protective cover, suitable for continuous heavy-duty operation

🚀 2. Pushing Performance

Parameter	Typical Range / Description
Pushing method	Linear reciprocating push-plate feeding; supports single-row / multi-row group pushing, matched to the hopper track width
Feeding cycle	Typically 20–60 parts/min, proportional to pushing frequency and parts per row; VFD speed adjustment available
Positioning accuracy	±0.05 mm with ball screw / servo drive; approx. ±0.2 mm with standard crank-linkage structure
Noise level	≤ 70 dB, significantly quieter than pneumatic pushers; no air supply or air-circuit maintenance required
Guiding system	Precision linear guide rails + wear-resistant pusher plate; smooth jam-free operation with maintenance-free lubrication
Start / stop behavior	Servo models support soft start/stop and positioning at any point, preventing workpiece shock and jumping

🏋️ 3. Load Capacity and Throughput

Parameter	Typical Range / Description
Applicable part size	Length 5–120 mm, diameter / across-flats 2–60 mm; track custom-built to part shape
Single part weight	Approx. 0.1–500 g; reinforced pusher plate and guide rails available for heavy parts
Parts per row	1–20 parts/row, depending on part size and track width; multi-row group pushing supported
Hopper capacity	Standard hopper holds approx. 500–5000 parts; optional vibrating hopper for automatic refill enables unmanned operation
Machine weight	Approx. 60–350 kg, depending on model and stroke

🔌 4. Electrical and Control Specifications

Parameter	Typical Range / Description
Control method	VFD speed control; servo models use PLC + servo positioning control with programmable stroke, speed, and cycle
Control interface	PLC / PC interfaces supported; can be synchronized with vibratory bowl feeders, linear feeders, and machining or assembly equipment
Detection	Standard photoelectric low-level sensor on the track; optional full-level auto stop and fault alarm output
Line integration	Works with automatic refill units, counters, and host controllers to build fully automated lines
Operating temperature	Standard 0–40°C; high-temperature motors and transmission parts available for hot environments

📋 5. Quick Selection Guide by Part Size

Part Size	Recommended Stroke	Recommended Motor Power	Recommended Frequency
Small parts (≤10 mm, ≤5 g)	30–80 mm	90–120 W	40–60 cycles/min
Medium parts (10–30 mm, 5–50 g)	60–150 mm	200–400 W	30–50 cycles/min
Large parts (30–60 mm, 50–500 g)	100–300 mm	400–750 W	20–35 cycles/min

Note: Actual feeding rate = pushing frequency × parts per row × number of rows. The table above is a general reference; final selection should consider part geometry, material, and line cycle requirements.
