Packaging Machine Spare Parts - Weighing Sensors

It is the core component for weight detection in fully automatic quantitative packaging machines. It belongs to high-precision force-sensing elements and directly determines the packaging weighing accuracy.

Packaging Machine Spare Parts - PTFE Packing

As a flexible packing seal for pump shafts, valve stems, and agitator shafts, it is filled into the equipment's packing box and compressed by a gland to fill the clearance between the shaft and achieve medium sealing to prevent leakage.

Bag Sewing Machine Head

Core sealing assembly for big bag packaging production lines. Mounted above the conveyor frame, it performs high speed sewing closure for woven bags, paper plastic composite bags and kraft paper bags filled with modified starch. It prevents starch dust leakage and moisture ingress. Interfaced with quantitative packaging scales and conveying equipment to deliver continuous automatic bag sewing operations.

Load Cell

Core metering element for modified starch quantitative packaging scales. Resistance strain gauge shear beam / cantilever beam load cell, normally 3 point mounted underneath the weighing hopper. Converts material weight into electrical signals sent to the weighing instrument for quantitative weighing control of modified starch powder.

Pneumatic Components

Actuation unit for modified starch quantitative packaging equipment. Driven by compressed air, it executes bag clamping, fast /slow feed gate opening closing, material discharging and pneumatic cutter actions for sewing machine heads. Cooperates with weighing control systems to realise fully automatic packaging workflows. Suited for fine dusty, slightly moisture absorbent modified starch production environment. Typical working air supply pressure: 0.5 0.7 MPa.

Conveyor Belt

Output conveying component for modified starch packaging equipment. Installed downstream of the bag sewing head. It receives fully sewn starch bags and smoothly conveys finished bags off line, completing final material transfer for the packaging sequence. Adapted for fine dust food grade modified starch production conditions.

Heat Sealing Machine Heating Strip

Core heating element for heat sealing packaging machines. Applied on heat seal stations for composite film and paper bag inner liners in modified starch packaging lines. Generates heat upon power on to melt and bond packaging materials and achieve bag mouth heat sealing, functionally different from stitch based bag sewing heads.

Photoelectric Sensor

Common detection sensor for modified starch packaging equipment. Uses light signal emission & reception to detect presence and position of packaging bags, sends switching signals to PLC and controls bag clamping, feeding, sewing and conveying mechanism actions for packaging line automatic interlock.

Bag Clamping Mechanism

Critical actuating assembly for quantitative packaging scales, pneumatically driven and fitted at weighing hopper discharge spout. Operators fit empty bags onto discharge nozzle; the mechanism clamps bag mouth for filling. Upon completion of metering, it automatically releases bags so packages drop onto downstream conveyor belts. Optimized for fine powder modified starch packaging duties.

Control Instrument Unit

Dedicated measurement and control unit for modified starch finished bag packaging machines. Integrates weighing instrument, temperature controller, counter module and frequency conversion control module. Performs quantitative weighing, heat seal temperature regulation, bag length counting and speed adjustment plus fault alarm functions. Monitors full process parameters for automatic feeding, heat sealing, cutting and bag sewing of powder products; safeguards bag weight precision, sealing quality and continuous machine operation.

Cutter Assembly

Key actuating component for fully automatic powder packaging machines. Cuts continuously fed heat seal film at preset bag lengths to separate finished individual packages, completing bag forming filling heat sealing cutting cycles. Directly determines cut edge neatness, dimensional accuracy and continuous operational stability of packaging equipment.

Heat Sealing Film

Roll form consumable material for automatic modified starch packaging machines. Inner layer melts under heat seal press assembly pressure to form bag seals. Primarily applied for sealed packaging of dried modified starch powder to resist moisture ingress and dust escape. Two major categories: single layer heat sealing film and multi layer composite heat sealing film. Food grade grades must comply with food contact safety standards.
