2. Control System: Equipped with Chinese and English touch screen control system for convenient operation, supporting multi-formula parameter storage and quick calling to reduce commissioning time for production changeover.
3. Core Components: Equipped with imported electrical components with stable performance to ensure reliability of long-term continuous operation.
4. Sealing Technology: Adopts high-power and high-precision sealing mould matched with high-quality heating tubes for heat sealing. The sealing lines are firm and clear, and sealing patterns can be customized to effectively enhance the overall product image.
5. Flexible Expansion: Optional vacuum feeder, date coder, inkjet printer, finished product conveyor, weight detector, bag arranging device and robot palletizing system according to material characteristics, realizing full-process automatic closed loop from feeding to palletizing.
6. Stable Operation: Pneumatic control box and circuit control box are independently separated, featuring low noise and stable circuit performance.
7. Dustproof Design: The whole machine adopts closed structure to effectively prevent dust from entering the interior, suitable for powdery material packaging scenarios.

IV. Full-process Automated Packaging Process

The automated packaging solution provided by Marchi Packaging Equipment fully covers the following production links until finished products are palletized and stored:

Step 1 — Automatic Feeding

Materials are conveyed to the metering hopper via vacuum feeder or storage bin to realize stable feeding according to granular or powdery material characteristics.

Step 2 — Bag Making and Filling

The packaging film is folded into bag shape on the former, and the cup metering device performs precise filling according to the preset weight of 1-100g, with automatic adjustment according to different material specific gravity.

Step 3 — Sealing and Bag Cutting

The bag body is conveyed to the sealing station. The heat sealing knife completes three-side sealing (customizable four-side sealing, back sealing and other bag types) and presses mesh or decorative sealing patterns. The cutter cuts according to the set bag width, with optional flat cutter, serrated cutter or rounded corner cutter.

Step 4 — Coding and Output

Finished packaging bags are output via the conveyor belt, while the linked date coder / inkjet printer prints production date, batch number and other information online. A weight detector can be installed to weigh each bag and reject unqualified products.

Step 5 — Bag Arranging and Sorting

Qualified bags after weight detection enter the automatic bag arranging device, arranged in groups according to preset quantity such as 10 or 20 bags per group, with the arranging speed linked and matched with the discharging speed of the main packaging machine.

Step 6 — Robot Palletizing

Grouped packaging bags are conveyed to the robot palletizing station through the conveying line. The palletizing system automatically stacks finished products on pallets according to set layers and arrangement modes, and conveys the whole pallet to the finished product temporary storage area or directly connects with delivery procedures after stacking is completed.

So far, the full-process automatic closed loop from material feeding, roll film bag making, material filling, sealing and cutting, coding output to final palletizing and warehousing is fully completed.

V. Customer Pain Points and Marchi Solutions

Aiming at the core concerns of food packaging enterprises in production line upgrading, Marchi Packaging Equipment provides the following targeted solutions:

Pain Point ①: Unstable sealing quality, air leakage or sealing damage after warehousing. Some packaging equipment has large batch-to-batch differences in sealing quality and low sealing qualification rate due to insufficient temperature control accuracy or fluctuating sealing pressure.

Marchi Solution: The equipment adopts high-performance precision sealing mould matched with high-quality heating tubes, with accurate sealing temperature control and stable sealing pressure. The sealing lines are firm and clear, and mesh, straight or decorative sealing styles can be customized as required to ensure consistent single-bag sealing quality and effectively reduce batch fluctuation.

Pain Point ②: Dust overflow and workshop cleaning problems, especially serious dust pollution when packaging powdery materials such as soybean milk powder and instant oatmeal. Traditional packaging equipment has insufficient sealing performance with high dust overflow rate during powder filling, affecting workshop operating environment and equipment service life.

Marchi Solution: The whole machine adopts closed structural design to effectively prevent dust from entering the interior. Meanwhile, the high-precision cooperation of sealing mould and heating tubes further reduces powder dispersion and improves workshop cleanliness. A dust removal device can be optionally equipped according to powder material characteristics to reduce dust overflow from the source.

Pain Point ③: Frequent material switching and long production changeover time affecting order switching efficiency. The oatmeal product line has diverse specifications involving multi-parameter adjustment such as bag type, weight and sealing mode, resulting in long downtime for production changeover and low overall equipment utilization.

Marchi Solution: The Chinese and English touch screen control system supports multi-formula parameter storage and one-key calling. Operators can quickly switch production parameters of different materials, greatly shortening commissioning time for production changeover. Sealing types such as three-side sealing, four-side sealing, back sealing and special-shaped bags can be customized to meet the packaging specification requirements of different product lines.

Pain Point ④: Unstable packaging accuracy and large gram weight deviation causing material waste or compliance risks. Some equipment has decreased metering stability during continuous operation, with single-bag gram weight deviation exceeding enterprise internal control standards and increasing material loss. In addition, the configuration is inflexible and cannot stably meet the packaging operation requirements of multi-form materials (granule + powder mixing).

Marchi Solution: Equipped with a cup metering system with a metering range of 1-100g, and the metering device can be customized according to different material specific gravity and customer requirements. The gram weight of materials is precisely controllable within the allowable range of material characteristics, ensuring that the weight of each bag meets quality requirements and effectively reducing material waste.

Pain Point ⑤: Packaging film deviation and bag making error affecting packaging appearance and production efficiency. Factors such as eccentric film roll installation, improper tension control or guide roller deviation may cause packaging film deviation, resulting in sealing misalignment and distorted bag shape, and even batch waste bags in serious cases.

Marchi Solution: Adopts advanced photoelectric eye control system to accurately control bag length. Cooperated with stable bag making former and servo film pulling mechanism, the packaging bag has good and beautiful forming effect with small belt wear, effectively eliminating packaging film deviation.
