I. Core Advantages and Application Scenarios of Automatic Quantitative Weighing Scale
Designed for granular and powdery materials, the automatic quantitative weighing scale integrates multiple functions including weighing, bag making, filling, sealing, coding, hole punching and counting. Marchi MC5000D automatic quantitative weighing scale adopts three-servo system to control film pulling and sealing, ensuring stable and reliable operation. Its control components are sourced from world-famous brands, and the overall design balances operational stability and easy operation.
The equipment is compatible with a wide range of materials, including but not limited to grains and crops such as rice, corn, wheat, sorghum, oats, buckwheat, soybean, mung bean, brown rice, black rice, red rice, coix seed, highland barley, barley, millet, glutinous rice, black bean, red bean, pea, broad bean, kidney bean, hyacinth bean, chickpea, cowpea, sesame, flaxseed, chia seed, quinoa, peanut and sunflower seed. It is also applicable to quantitative packaging of feed, chemical fertilizer, chemical granules, plastic pellets, condiments, coffee beans, nuts and other granular materials.
In terms of application fields, the equipment is widely used in grain processing plants, feed manufacturers, fertilizer and agricultural material factories, food processing workshops, grain and oil trading and warehousing enterprises. MC5000D delivers stable performance for large-bag packaging of bulk grains as well as small-specification fine packaging. Our services cover the whole country including Shandong, Guangdong, Henan, Hebei, Jiangsu, Zhejiang, Sichuan, Hunan, Hubei, Anhui, Shanxi, Shaanxi, Inner Mongolia, three northeastern provinces, Xinjiang and other regions, providing timely technical support and after-sales service for customers.
II. Core Configuration and Key Parameters
MC5000D automatic quantitative weighing scale is composed of MC5000D vertical filling packaging machine, linear weigher and bucket elevator.
Equipment Model: MC5000D
Bag Size L×W (mm): (50～340)×(80～250) (The range varies slightly with different configurations, subject to actual material characteristics)
Applicable Bag Types: Pillow bag, gusset bag, hole-punched bag, hand-held bag, box bag, etc.
Metering Range (g): 10～2000 (The range varies slightly with different configurations and can be adjusted on demand)
Metering Accuracy: ±0.2%～0.5%
Packaging Speed: 25～80 bags per minute
For core configuration, the three-servo system controls film pulling and sealing to optimize stable operation and packaging speed simultaneously. All control components adopt internationally renowned brands to guarantee long-term reliable operation at the hardware level. The equipment supports non-standard customization. Parameters and structures can be optimized according to different material characteristics and packaging specifications to meet diversified production demands.
III. Packaging Process — Full Automatic Operation from Feeding to Palletizing
The complete workflow of the automatic quantitative weighing scale covers all procedures from material lifting, metering and filling to final palletizing with full automatic control.
Step 1: Material Lifting and Feeding. The bucket elevator conveys materials from the storage bin to the hopper of the linear weigher. Cooperated with the material level control system, it realizes continuous and stable feeding to ensure non-stop production.
Step 2: Automatic Weighing and Metering. The linear weigher completes high-precision weighing. Two-stage feeding control of high speed and low speed keeps the weight error of each bag within ±0.2%～0.5%. The system monitors weighing data in real time and starts discharging automatically when reaching the standard weight.
Step 3: Automatic Bag Making and Filling. MC5000D vertical filling packaging machine finishes automatic bag forming and fills weighed materials into bags. Multiple bag types are optional including pillow bag, gusset bag, hole-punched bag, hand-held bag and box bag according to product positioning.
Step 4: Automatic Sealing and Coding. Sealing is completed right after filling. Optional coding device can print production date, batch number and other information, and the hole punching function is available for hand-held bags.
Step 5: Conveying and Inspection. Finished products are delivered via conveyor belts. Optional weight rechecking and metal detection devices automatically reject unqualified products.
Step 6: Automatic Palletizing. Qualified bagged products are sent to the palletizing station through the conveying system. Palletizing manipulators or automatic palletizers stack bags neatly on pallets following preset procedures, completing the full automatic packaging process from raw materials to finished products.
This whole process realizes full-link automation of feeding, weighing, bag making, filling, sealing, coding and palletizing, greatly reducing manual intervention.
IV. Customer Pain Points and Corresponding Solutions
Based on long-term service experience with nationwide customers, Marchi summarizes typical industry pain points and targeted solutions as follows.
Pain Point 1: Low efficiency of traditional packaging failing to match upstream production capacity
Manual packaging has limited speed, which easily leads to semi-finished product accumulation and delayed order delivery.
Solution: Adopt the automatic quantitative weighing scale. The packaging speed reaches 25～80 bags per minute to greatly boost output and match the cycle of upstream production lines.
Pain Point 2: Unstable weighing accuracy causing heavy material loss
Manual weighing and semi-automatic equipment tend to produce excessive errors, resulting in raw material waste and customer complaints.
Solution: Equipped with high-precision linear weigher and intelligent control algorithm, the metering accuracy is controlled within ±0.2%～0.5% to reduce loss caused by overweight or insufficient weight fundamentally.
Pain Point 3: Rising labor cost and difficulty in recruiting skilled workers
Packaging workshops require a large number of workers with high personnel turnover rate.
Solution: The fully automatic equipment realizes full-process operation from feeding to palletizing, drastically cutting down labor demand in packaging links and long-term labor costs.
Pain Point 4: Complicated bag type switching leading to low equipment utilization
Traditional equipment takes much time and effort to switch between different bag types for various products.
Solution: MC5000D supports multiple bag types including pillow bag, gusset bag, hole-punched bag, hand-held bag and box bag. Parameters can be adjusted for quick switching to improve overall equipment utilization.
Pain Point 5: Poor equipment stability and high maintenance cost
Low-cost equipment is prone to frequent failures and interrupt continuous production.
Solution: Marchi equipment adopts internationally famous control components and three-servo system for film pulling and sealing to ensure stable operation. We provide one-year warranty and lifelong maintenance service to eliminate customers' worries.
