I. Model Selection: Why Choose MC5000D
Tea products feature diverse forms and various packaging bag requirements. MC5000D vertical filling packaging machine supports multiple bag types including pillow bag, gusset bag, hole-punched bag, hand-held bag and box bag. The bag length ranges from 50mm to 280mm and bag width ranges from 70mm to 200mm. The metering range is 10g to 500g, and the packaging speed is 25 to 80 bags per minute. It supports one-key switching of 10 sets of formulas for convenient production changeover, which is ideal for flexible production of multiple products.
II. Core Configuration: Three-servo System and High-quality Components
Equipment stability relies on core configuration. MC5000D adopts three-servo system to control film pulling and sealing, which avoids mechanical gear wear and ensures high precision of bag length adjustment. No parking fine-tuning is required during film replacement. The control components adopt internationally renowned brands and are built with automatic fault diagnosis function. The machine will give an automatic alarm and display handling suggestions in case of low air pressure, heating tube open circuit or metering deviation, reducing unexpected shutdowns.
III. Detailed Packaging Process: From Linear Weighing to Automatic Palletizing
The complete packaging process includes the following steps:
- Automatic Feeding and Weighing: The bucket elevator conveys tea stably to the linear weigher. The linear weigher adopts three-stage feeding of high speed, medium speed and low speed. Real-time weight feedback ensures metering accuracy within ±0.2%～0.5%. The closed weighing chamber effectively reduces dust overflow.
- Bag Making and Filling: The packaging film is folded into tubular shape by the former. The three-servo system pulls the film precisely to complete back sealing or three-side sealing. Materials fall into bags through the discharging pipe, followed by transverse sealing, cutting, coding and optional hole punching. All actions are completed synchronously.
- Finished Product Conveying and Sorting: Finished bags are delivered by conveyor belts. Optional weight rechecker and metal detector automatically remove unqualified products. Qualified products are arranged neatly by sorting belts.
- Automatic Bag Arranging and Palletizing: The bag turning device unifies the orientation of all bags. Palletizing robot or mechanical palletizer stacks products automatically in preset patterns, such as 5×4 bags per layer and 8 layers per pallet. Partition boards can be installed optionally. Pallets with stacked products are moved out automatically, realizing fully automatic connection from raw tea materials to finished pallets.

VI. Four Major Customer Pain Points and Marchi Solutions
Pain Point 1: High rate of broken tea
Cause: Large material drop distance.
Solution: Adopt multi-stage deceleration feeding of linear weigher and low-speed buckets of bucket elevator. Buffer slopes are set on material passages to keep tea intact.
Pain Point 2: Dust pollution
Cause: Unclosed structure during weighing and filling.
Solution: Install dustproof cover on the weighing chamber and adopt soft connection sealing for discharging passages. Dust removal interfaces can be equipped optionally.
Pain Point 3: Frequent shutdown and maintenance
Cause: Wear of mechanical contacts and lack of fault early warning.
Solution: The three-servo system reduces wearing parts. PID temperature self-tuning and alarm function are equipped. The equipment automatically reminds operators to clean sensors and replace cutting blades.
Pain Point 4: Long time for production changeover
Cause: Manual mechanical adjustment is required.
Solution: 10 sets of formulas can be called with one click. Parameters including bag length, metering value, temperature and speed can be switched rapidly, and the production changeover time is controlled within 10 to 15 minutes.
