How to select a plastic pellet packaging machine

The plastic granule packaging machine features manual bagging and automatic weighing and discharging by machine. It is suitable for large bag packaging of 10 to 50 kilograms and is the mainstream choice for plastic granulation, modification, and trading enterprises. The following is detailed information about the plastic granule packaging machine:

I. Core Structure and Working Principle of Plastic Granule Packaging Machine

The main components of the plastic granule packaging machine are: storage hopper, feeding mechanism (vibration / screw), weighing hopper, weighing sensor, bag clamping device, PLC control system, touch screen, and frame (304 stainless steel for the part in contact with materials).

Process:

Manual bagging → Automatic bag clamping by the bag clip

The equipment features dual-speed feeding, fast and slow (coarse weighing + fine weighing).

When the set weight is reached, stop feeding.

Open the bag → The bag drops → Manual sewing of the bag

Advantages: High precision, stable speed, low failure rate, and labor-saving.

II. Core Parameters of Plastic Granule Packaging Machine (General for Plastic Granules)

Weighing range: 10 - 25kg / 20 - 50kg (mainstream 25kg)

Packaging speed: 480 to 600 bags per hour (8 to 10 packs per minute)

Measurement accuracy: ±0.1% to ±0.2% (25kg ≈ ±25 to 50g)

Feeding method: Vibrating feeding (general purpose) / Servo screw feeding (high precision, anti-crushing)

Control: PLC + 7-inch touch screen, one-key switch between weight and automatic accumulation.

Power supply: 380V 50Hz, power approximately 2.2 to 3kW

Material: Contact material is 304 stainless steel, anti-corrosion and non-stick.

III. Selection and Implementation Suggestions for Plastic Granule Packaging Machines

Test the machine first before deciding: Use your company's compound fertilizer samples to conduct actual tests at the factory to verify the stability and ±0.1% accuracy. Continuously test 20 to 30 bags and observe the fluctuation of errors.

Material compatibility confirmation: Confirm whether the dual-hopper feeding method (screw / vibration) is compatible with the particle size and moisture content of your company's materials to avoid material blockage or dust generation.

After-sales service and spare parts: Clearly define the on-site commissioning cycle and the supply cycle of vulnerable parts (such as sensors and sealing rings) to ensure stable operation in the long term.

Specification matching: Confirm whether the 10–50kg one-click switching function covers your company's mainstream packaging specifications (such as 25kg, 50kg).
