Key Features of Automatic Melon Seed Pouch Packing Machine

High-Precision Intelligent Weighing with Stable Accuracy

Equipped with a 14-head 2.5L professional multihead weigher adopting advanced dynamic weighing sensor technology and intelligent drop correction algorithm, the machine supports multi-channel simultaneous weighing. It effectively avoids weighing errors caused by material accumulation and uneven feeding, ensuring stable and accurate weighing data in long-term operation. It greatly reduces material loss and rework rate, significantly improving production yield.

Full-Automatic Operation for Cost Reduction & Efficiency Improvement

The entire production line realizes full-process automatic operation including material conveying, quantitative weighing, bag picking, bag opening, filling, sealing and finished product output. It greatly reduces manual intervention, cuts labor costs and eliminates human operation errors. Standardized assembly line operation ensures uniform packaging specifications and neat appearance of each batch of products, effectively improving production efficiency and product consistency.

Precise Formula Dosing for Diversified Production

The equipment supports custom setting of material formula and quantitative parameters, enabling accurate weighing and dosing of small granular materials with different weights and proportions. It perfectly adapts to differentiated production standards and meets enterprises’ refined and diversified packaging production requirements.

Flexible Adjustment for Multi-Specification Products

All core parameters including weighing weight, packaging speed, sealing specifications and pouch size can be flexibly adjusted with one click. No equipment replacement or complex modification is required to adapt to packaging products of different sizes and specifications. It features high equipment utilization and fully supports enterprises’ product iteration and multi-category production layout.

Mechanical Characteristics of Each Unit

1. Vibrating Feeder – Stable & Continuous Material Supply

   Adopting intelligent vibration feeding principle with adjustable and uniform vibration frequency, the feeder conveys granular materials such as melon seeds to the next process stably and orderly. It effectively prevents material accumulation, jamming and feeding interruption, ensuring non-stop continuous operation of the assembly line and providing stable material supply for high-precision weighing.

2. Inclined Elevator – Efficient Material Lifting & Conveying

   With a professional inclined structure designed for granular material characteristics, the elevator stably lifts materials to the optimal working height for weighing and packaging procedures. It avoids material spilling and damage during conveying, features stable operation and strong load capacity, and is fully applicable to long-term continuous mass production.

3. 14-Head 2.5L Multihead Weigher – Core High-Efficiency & Precision Weighing Unit

   As the core weighing unit of the entire production line, the multi-head synchronous weighing design realizes simultaneous metering of multiple groups of materials, greatly improving weighing efficiency. Equipped with high-sensitivity weighing sensors, it collects weight data in real time and strictly controls the weighing error within ±0.5g, achieving a perfect balance between high-speed production and high-precision weighing for standardized mass production.

4. Pouch Packaging Machine – Standardized Finished Product Sealing

   The packaging machine automatically completes bag picking, opening, precise filling, heat sealing and finished product discharging. It is compatible with various materials and sizes of pre-made pouches. The flat and firm sealing ensures excellent airtightness, effectively preventing materials from moisture and damage, improving product shelf life and terminal display appearance.
