Automatic Weighing Packaging Detecting System | Multihead Weigher VFFS Line
Fully automatic weighing packaging detecting line equipped with multihead weigher, VFFS machine, checkweigher and metal detector for snack, puffed food, hardware and plastic materials, custom solution available.
Integrated Multihead Weighing, VFFS Packaging & Online Inspection Production Line
Product Overview
This typical weighing, packaging and detecting system is a standard fully automatic integrated production line, which integrates material lifting, high-precision quantitative weighing, vertical automatic packaging, finished product conveying, online weight checking and metal foreign body detection.
With a scientific and compact overall design, stable operation and high degree of automation, the system is widely used in snack food, puffed food, hardware, plastic and rubber industries. It not only realizes efficient automated packaging production, but also completes full-process quality inspection online, effectively ensuring product net content compliance and food safety, and is an ideal choice for mass production enterprises to improve efficiency and control quality.
System Composition
The complete production line consists of 7 core units, all of which adopt coordinated linkage control, and can be flexibly added or reduced according to actual production requirements:
1. Bucket Elevator
As the front-end feeding equipment, the bucket elevator continuously and stably lifts bulk materials from the ground storage hopper to the feeding inlet of the multihead weigher. It adopts a durable bucket structure with smooth feeding, no material damage and no scattering, which is suitable for most granular and block materials.
2. Multihead Weigher
Equipped with a high-precision multihead combination weigher, it adopts an intelligent combination weighing algorithm to quickly and accurately complete quantitative weighing of materials. It has a wide weighing range and high precision, which effectively reduces packaging weight error and material waste, and ensures the consistency of each package of products.
3. Supporting Platform
The all-steel structure working platform provides stable support for the multihead weigher and operation space for personnel. With a solid structure and shock absorption design, it effectively avoids the influence of equipment operation vibration on weighing accuracy, and is equipped with safety guardrails to ensure safe operation and daily maintenance.
4. Vertical Packaging Machine (VFFS)
The vertical form fill seal machine automatically completes the whole process of roll film forming, bag making, material filling, sealing, date coding and finished product cutting. It supports a variety of bag types such as pillow bag, gusset bag and perforated connected bag, with fast packaging speed and low packaging material cost, suitable for mass continuous production.
5. Finished Product Conveyor
The belt conveyor smoothly transports the packaged finished products from the packaging machine outlet to the rear inspection station. It perfectly connects the packaging process and the detection process, ensures the continuous and stable operation of the whole line, and avoids product accumulation or falling.
6. Check Weigher
The online dynamic check weigher performs 100% weight detection on each finished product passing through the production line. It automatically identifies and rejects products with unqualified net content, and synchronously counts production data, helping enterprises strictly control product weight standards and meet regulatory requirements.
7. Metal Detector
The high-sensitivity metal detector can accurately detect ferrous metals, non-ferrous metals and stainless steel impurities mixed in products. When metal foreign bodies are detected, the system automatically triggers the rejection device to remove unqualified products, which is a key guarantee for food safety and product quality, and meets the quality management standards of various industries.
Applicable Materials & Industries
Snack Food
Nuts, dried fruits, roasted seeds and nuts, candy, dried meat slices, preserved fruits, etc.
Puffed Food
Potato chips, popcorn, puffed sticks, extruded snacks, crispy rice, etc.
Hardwares
Screws, nuts, bolts, fasteners, small hardware fittings, metal parts, etc.
Plastic & Rubber
Plastic granules, rubber parts, injection molding accessories, raw material particles, plastic products, etc.
System Features & Advantages
Coordinated Central Control, High Automation & Low Energy Consumption
The whole system adopts unified coordinated control, and all units are linked automatically. From material feeding, weighing and packaging to finished product inspection and rejection, the whole process is automated without manual intervention. The whole line has a high degree of automation, low energy consumption per unit output, which effectively reduces labor costs and improves production efficiency.
Solid Platform Design to Ensure Weighing Accuracy
The working platform adopts a reinforced steel structure design with reasonable stress and stable structure. It is equipped with a shock absorption treatment structure, which effectively isolates the vibration interference of the packaging machine and conveying equipment to the weighing unit, ensuring that the high-precision weighing performance of the multihead weigher is not affected by the operation of the whole line.
Scientific Line Design, Stable Operation & Excellent Weighing Performance
The complete line adopts a simple and scientific overall layout, with smooth process connection and stable and reliable long-term continuous operation. The system has a wide weighing range and high weighing accuracy, and can flexibly adapt to different packaging specifications and output requirements, with strong production adaptability.
Wide Application Range, Integrated Production & Inspection
The system is suitable for weighing, packaging and quality inspection of various granular, block and irregular materials in multiple industries. It integrates production packaging and online quality inspection, which not only improves production efficiency, but also strictly controls product quality from two dimensions of net content and foreign body safety, helping enterprises improve product qualification rate and brand reputation.
Working Flow
1. Material Lifting
Bulk materials are lifted from the ground hopper to the multihead weigher through the bucket elevator to realize automatic continuous feeding.
2. Precision Weighing
The multihead weigher automatically combines and weighs materials according to the set target weight, and discharges accurately weighed materials into the vertical packaging machine.
3. Automatic Packaging
The VFFS machine completes bag making, filling, sealing, coding and cutting in sequence according to the set parameters to produce independent finished packaging.
4. Conveying & Inspection
Finished products are transported to the inspection section through the finished product conveyor, and pass through the check weigher and metal detector in turn for full inspection.
5. Automatic Rejection
Products with unqualified weight or containing metal impurities are automatically removed by the rejection device, and qualified finished products are smoothly output for subsequent boxing and warehousing.
