Efficient process flow of fully automatic powder filling machine
Date: 2025-12-30Read: 4
As the core equipment of modern packaging industry, the fully automatic powder filling machine is widely used in fields such as food, medicine, and chemical industry due to its high efficiency and precision. Represented by Shanghai Haochao, domestic equipment has achieved full process automation from raw material processing to finished product packaging through modular design and intelligent control.
1、 Core process flow: Four step closed-loop to achieve efficient production
1. Preprocessing and feeding system
Raw material screening: Powder is removed from clumps through vibrating or air flow screens to ensure fluidity. For example, milk powder production requires the use of 80-100 mesh sieves to avoid filling blockages.
Vacuum feeding: The negative pressure conveying system sucks the powder into the stainless steel silo to reduce dust pollution. Pesticides and other volatile materials need to be equipped with nitrogen protection devices.
Material level monitoring: Ultrasonic sensors monitor the inventory of the material bin in real time, triggering automatic replenishment instructions to avoid material interruption and shutdown.
2. Precise filling stage
Screw metering: The servo motor drives the spiral rod to rotate, achieving a filling volume of 0.5-5000g by controlling the speed and number of turns. The accuracy can reach ± 0.5%, suitable for pharmaceutical grade powders.
Adaptive positioning: The photoelectric sensor recognizes the position of the container, and the robotic arm automatically adjusts the height of the filling head, compatible with various packaging such as penicillin bottles and aluminum foil bags.
Dustproof design: The filling area is equipped with a negative pressure dust removal system to ensure that the cleanliness of the GMP workshop meets the standard.
3. Sealing and coding integration
Pneumatic capping: The torque adjustable capping machine automatically locks the aluminum cap with a pressure range of 0.2-0.8N · m to avoid glass bottle damage.
Laser marking: Engrave the production date and batch number on the packaging surface, with adjustable character height of 0.3-2mm, in compliance with FDA traceability requirements.
Weight re inspection: The dynamic weighing module eliminates products with insufficient filling, and the defect rate is controlled below 0.1%.
4. Post processing and cleaning
Automatic exclusion: The visual inspection system recognizes appearance defects and guides defective products into the waste bin through pneumatic push rods.
CIP cleaning: The detachable filling head supports on-site cleaning, with automatic drying after 60 ℃ hot water circulation flushing, reducing downtime by 80% when replacing products.
Data traceability: The PLC system records production parameters and supports QR code scanning to query the entire data process.
