Description

Technical Field

[0001] This utility model belongs to the field of weighing and packaging technology, and in particular relates to a ton bag packaging machine with integrated upper and lower weighing. Background Technology

[0002] Some metallurgical products have a large range of material specific gravity produced on the same production line. For example, two materials with specific gravity of 1000Kg / m³ and 5000Kg / m³ powder respectively are both packaged in ton bags. A 1 cubic meter ton bag can hold 1 ton and 5 tons of the two materials respectively. Due to the strength of the woven bag, the 5-ton bag cannot withstand a 5-ton pulling force to lift the bag. Therefore, the 1-ton bag can be packaged on an upper metering ton bag packaging machine, while the 5-ton bag can only be packaged on a lower metering ton bag packaging machine.

[0003] Currently, many materials with varying specific gravities require multiple ton bag packaging machines. When multiple ton bag packaging machines are used for weighing and packaging, two storage silos and two sets of conveying equipment need to be added upstream of the packaging machine, resulting in a significant additional investment. Therefore, there is a need for an integrated upper and lower weighing ton bag packaging machine that can weigh and package materials with varying specific gravities, avoiding the need for users to configure multiple ton bag packaging machines for weighing and packaging, and reducing the cost of weighing materials with varying specific gravities.

The top of the fixed frame 3 is fixedly installed with four symmetrical upper weighing platforms 10. The top of the fixed frame 3 is fixedly installed with two symmetrical support frames 11. The top of the upper weighing platform 10 and the support frames 11 are fixedly installed with four symmetrical cylinders 12.

[0023] Working Principle: When using this invention, the user hangs the ton bag with the lifting strap on the surface of the pneumatic clamp 13, so that the bag opening is covered by the pneumatic bag clamp 14. At this time, the bottom of the ton bag is at the top of the lower weighing platform 2. The screw feeder 6 and the pneumatic butterfly valve 7 are started to discharge material. At the same time, the lower weighing platform 2 weighs the ton bag at its top. When the predetermined weight is reached, the screw feeder 6 and the pneumatic butterfly valve 7 are closed, and the pneumatic clamp 13 is activated to detach from the ton bag, completing the weighing and packaging of high-density materials. When weighing low-density materials, the above steps are repeated, hanging the ton bag with the lifting strap on the surface of the pneumatic clamp 13, so that the bag opening is covered by the pneumatic bag clamp 14. The upper weighing platform 10 starts by activating cylinder 12, which drives the lifting bag platform 9 upward. This causes the lifting bag platform 9 to lift the ton bag via pneumatic clamp 13. The screw feeder 6 and pneumatic butterfly valve 7 are then activated to release the material. At this time, the upper weighing platform 10 weighs the ton bag below the lifting bag platform 9. When the predetermined weight is reached, cylinder 12 is activated to move the lifting bag platform 9 downward. When the ton bag reaches the top of the lower weighing platform 2, the pneumatic clamp 13 is activated to disengage from the ton bag, completing the weighing and packaging of high-density materials. This avoids the need for users to configure multiple ton bag packaging machines for weighing and packaging, reducing the cost of weighing various materials with different densities.

[0024] In summary, this integrated weighing ton bag packaging machine, by hanging the ton bag with its straps on the surface of the pneumatic clamp 13, and activating the screw feeder 6 and the pneumatic butterfly valve 7, allows the material to enter the ton bag. At this time, the lower weighing platform 2 weighs the material. When weighing materials with low specific gravity, the cylinder 12 is activated, causing the lifting bag platform 9 to move the ton bag upward through the pneumatic clamp 13, so that the upper weighing platform 10 weighs the materials with low specific gravity. This allows for the weighing and packaging of materials with various specific gravityes, avoiding the need for users to configure multiple ton bag packaging machines for weighing and packaging, and reducing the cost of weighing materials with various specific gravityes.
