The working principle and structural characteristics of the fully automatic rotary bag feeding packaging machine
Date: 2025-10-21Read: 5
The fully automatic rotary bag feeding packaging machine realizes the integration of "automatic bag picking, material filling, and sealing molding", suitable for batch packaging of prefabricated bags. The core design revolves around "rotating station connection, adaptation to multiple bag types, and reduction of manual intervention", and is widely used in the fields of food, chemical, and medicine.
1、 Working principle: Collaborative packaging process with rotating workstations
With the "rotating host" as the core, multiple circular workstations complete packaging in sequence, without the need for manual intervention:
1. Supply and retrieval of prefabricated bags
Prefabricated bags are stacked in the feeding mechanism material bin and transported to the bag picking station through conveyor belts or suction cups;
The vacuum suction cup or mechanical gripper grabs a single bag and sends it to the bag clamping station of the rotating host for clamping, which flows with the host;
Set up a bag type detection component to automatically remove empty, oversized, or skewed bags to avoid affecting the subsequent process.
2. Bag opening and material filling
Transfer from the bag clamping station to the bag opening station, and use pneumatic grippers to open the bag opening;
After transferring to the filling station, use screw conveyors, measuring cups, etc. to inject materials according to their types (particles/powders/liquids);
After filling, check if there are insufficient or excessive bags marked, and remove them later.
3. Bag opening organization and sealing
Go to the sorting station, smooth out the wrinkles on the bag opening, and remove residual materials;
Enter the sealing station and seal the bag material using methods such as heat sealing and ultrasonic sealing;
After sealing, inspect and sort out non-conforming products that have been missed or falsely sealed.
4. Finished product output and removal of non-conforming products
Qualified finished bags are transferred to the unloading station, the bag clamping mechanism is released, and transported downstream by the conveyor belt;
Unqualified products marked in the early stage (empty bags, abnormal filling/sealing) were pushed away from the removal station and collected separately.
2、 Main structural features: design advantages for adapting to multiple scenarios
Designed around "strong adaptability, easy operation, stable and reliable", the core components meet industry needs:
1. Rotating host: core support and workstation collaboration
Multi station circular distribution, arranged around the axis of the host, with rotation speed matching the rhythm of each link to ensure continuous operation;
The host frame is made of rigid materials such as stainless steel, which has low operating vibration, wear resistance, and can withstand the forces of various processes.
2. Bag feeding and opening system: compatible with multi specification prefabricated bags
The bag feeding mechanism can adjust the width of the seasoning compartment and the position of the bag taking components, adapting to different sizes of prefabricated bags, and switching without the need to replace a large number of components;
The bag opening gripper can adjust the clamping force and is compatible with various materials such as PE bags and composite bags to avoid bag damage or opening failure.
3. Material filling system: adapted to different material characteristics
Design components according to material types: anti crushing conveying for particles, anti flying closed conveying for powders, and anti drip filling for liquids;
The filling amount can be quickly adjusted through the control panel, without the need to disassemble components, and is suitable for packaging specifications ranging from a few grams to several kilograms.
4. Sealing system: ensuring sealing effect and adaptability
The sealing component can adjust temperature, pressure, and time, and is compatible with materials such as PE and PET composite film. It supports sealing with zipper bags and aluminum foil bags;
The sealing area is equipped with heat dissipation and anti sticking structures to prevent material adhesion, reduce cleaning frequency, and ensure stable sealing.
5. Control system and auxiliary support
The touch control panel can set parameters (packaging speed, filling amount, etc.) and display real-time workstation status (quantity, faults);
There are abnormal protections such as card bags and material shortages, automatic shutdown alarms, and fault information; The key components are detachable for easy maintenance.
The fully automatic rotating bag packaging machine relies on the collaborative and adaptive structure of the rotating station to achieve fully automated packaging of prefabricated bags. Adapt to multiple industries, adjust components according to materials and bag types to achieve stable and continuous operation, and assist in mass production.
