Gravity type bulk packaging machine and gravity type net heavy-duty packaging machine are two common types of packaging equipment. They have some differences and similarities in their working principles and application scopes. The following will provide a brief comparison and analysis of these two packaging machines.
Performance Overview
Gravity type heavy-duty packaging machine
The gravity-type bulk packaging machine adopts a gravity self-flow feeding structure and a gross weight intelligent weighing mode. It achieves weighing control through high-precision weighing sensors and can ensure the accuracy of weighing speed and weight measurement. This equipment can automatically complete processes such as bag clamping, filling, weighing, bag loosening, and conveying. It is equipped with a belt conveyor and an automatic sealing device, forming an automated packaging production line. It is suitable for powdery and granular materials with good fluidity, as well as low-capacity open bag quantitative packaging, such as PVC, polyurethane, compound fertilizers, plastic particles, quartz sand, mineral powder, etc.
Gravity-type heavy-duty packaging machine
The gravity-type net heavy packaging machine also adopts a gravity self-flow feeding structure, but it uses a net weight weighing drum-type intelligent weighing mode. The single-scale or double-scale structure is selected according to the production capacity. It also has high-precision weighing sensors and secondary or tertiary feeding accuracy control of large and small sizes, ensuring the accuracy of weighing speed and weighing quantity. The equipment can automatically complete the processes of bag clamping, filling, weighing, bag loosening and conveying, and is equipped with corresponding automated packaging production line equipment. It is suitable for fluid materials such as powders and granules, and is used for quantitative packaging of open bags with high production capacity and weighing accuracy requirements, such as PVC, polyurethane, compound fertilizers, plastic particles, quartz sand, mineral powder, etc.
Differences and Similarities
1. Working principle: The working principles of the two packaging machines are slightly different. The bulk-type packaging machine weighs based on the gross weight of the materials, while the net-type packaging machine weighs based on the net weight of the materials.
2. Weighing mode: The bulk packaging machine adopts the gross weight weighing mode, while the net packaging machine adopts the net weight weighing mode.
3. Application Scope: The application scope of the two packaging machines is basically the same. Both are suitable for the open-pouch quantitative packaging of powdery and granular materials with good fluidity, such as PVC, polyurethane, compound fertilizers, plastic particles, quartz sand, and mineral powder, etc.
4. Degree of Automation: Both packaging machines have a high degree of automation, capable of performing tasks such as bag clamping, filling, weighing, bag unclamping, and transportation, and are equipped with corresponding automated packaging production line equipment.
In summary, the gravity type bulk packaging machine and the gravity type net-type packaging machine differ in their working principles and weighing modes. However, they have the same application scope and degree of automation, and can both meet the quantitative bag-opening packaging requirements for powdery and granular materials with good fluidity.
