    Product Advantages

    Fast Packing Speed, Wide Application
    Different materials feeding ways are optional based on production technology to meet different requirement of packing speed and materials property.
    Easy Operation and Maintenance
    Special design, one operator to finish all work. conveyed by belt and weighed directly, can connect to hot melting device and sewing machine after weighing.
    High Packing Accuracy and Intelligence
    Adopt international-famous Mettler-Toledo weighing sensor and the scale accuracy is up to 0.02% which ensures the packing accuracy; equipped with auto control meter to realize auto feeding; with functions of auto reset when start machine, automatic correction of weight error, power-off protection, fault detection, can restore the factory Settings if wrong operation, etc., the intelligent advantage is obvious.
    Environmentally-friendly, can be customized
    Can be equipped with dust collector port, connecting to dust collector to have nice working environment. Can be customized into ex-proof type, automatic type,and entire stainless steel type(meet GMP standard).

      • Top open Bag Semi-Auto Packing Machine working principle

      Working Principle

      The machine consists of feeding system, bags-clamping and weighing system, control system, frame, pneumatic control system. The feeding system is with double speed, fast feeding ensures production capacity, and slow feeding under the control of Inverter to ensure feeding accuracy.
      The bags-folding weighing system consists of loading frame, sensor, folder arm. The frame supports the whole system and ensures stability. The control system controls feeding valve and folding bags. Its operation procedure is as following: manually put bags on, and clamp bags in place, the storage hopper with enough materials opens valve automatically and charge bags with materials, at the same time, it weighs. When it comes to the set working point, it closes the big control valve(screw), and goes to slow feeding. When it comes to the second working point, it closes the slow speed valve(screw), then it stops feeding, displays weight and release bags automatically.
