When purchasing jumbo bag packaging machines, enterprises often face various confusions: How to handle materials with poor fluidity? How to solve heavy dust problems? How to meet explosion-proof requirements? Different manufacturers have similar equipment parameters, but the actual use effects vary greatly. The fundamental reason is that the matching degree between packaging equipment and materials determines the final effect. As a professional jumbo bag packaging machine manufacturer, Marchi Packaging Equipment not only provides high-quality automatic jumbo bag packaging machines, but also offers full-process customized services from selection to delivery to ensure a perfect match between equipment and material characteristics.
I. Material Testing: The First Step for Accurate Selection
Marchi has material testing centers in Guangzhou and Hefei. It can conduct actual packaging tests on materials provided by customers including graphite powder, calcium carbonate, titanium dioxide, ABS powder, PVC powder, urea, feed additives, bentonite, kaolin, silica powder, alumina, aluminum hydroxide, flame retardant, polyacrylamide, cellulose, starch, flour, white sugar, salt, monosodium glutamate, washing powder, soap powder, desiccant, industrial salt, chemical fertilizer, compound fertilizer, organic fertilizer, cement, putty powder, gypsum powder, lime powder, talcum powder, heavy calcium powder, light calcium powder, quartz sand, ceramsite sand, emery sand, glass beads, plastic granules, rubber granules, resin granules, biomass granules, wood chip granules, activated carbon, carbon black, fumed silica, pigment powder, dye powder, iron oxide red, iron oxide yellow, cobalt powder, nickel powder, manganese powder, copper powder, aluminum powder, magnesium powder, zinc powder, molybdenum powder, tungsten powder, tungsten carbide powder, lithium iron phosphate, ternary materials, lithium cobalt oxide, lithium manganate, anode graphite, silicon-carbon anode, electrolyte additives, pharmaceutical intermediates, food additives, feed-grade additives, enzymes, probiotics, yeast powder, milk powder, soybean milk powder, protein powder, creamer, coffee powder, cocoa powder, matcha powder, solid beverages, seasonings, flavors and fragrances, preservatives, antioxidants, thickeners, emulsifiers, stabilizers, leavening agents, colorants, sweeteners, acidulants, amino acids, vitamins, antibiotics, pesticide technical materials, herbicides, insecticides, fungicides, plant growth regulators, surfactants, detergent raw materials, cosmetic raw materials and daily chemical powders. The optimal feeding method, lifting parameters and dust removal configuration are determined according to the test results to ensure accurate equipment selection.
II. Core Configuration: Customized Tailor-made
This automatic jumbo bag packaging machine adopts gross weight weighing and metering method. The bulk bag is hung on the weighing platform for rapid material filling. The equipment consists of six major parts: feeding device, weighing platform, lifting mechanism, bag hanging-releasing/clamping device, air inflation/return air dust removal pipeline and steel structure frame.
- Feeding Device: Adopts double-screw feeding structure, feeding by material self-weight, and flexibly controlling feeding flow through frequency conversion speed regulation. A cut-off butterfly valve is installed at the outlet of the single arc feeding gate to prevent residual materials from falling. The professionally designed pneumatic shifting fork mechanism effectively prevents powder arching and bridging in the feeding area.
- Weighing Platform: Equipped with weighing sensors featuring high comprehensive accuracy, good long-term stability and impact resistance, together with a special force transmission connection structure, it has multiple functions such as overload protection and limit protection.
- Lifting Mechanism: Fixed on the weighing platform, including cylinder lifting mechanism and four guiding mechanisms. It can lift up and down several times according to the filling condition to ensure the best filling effect.
- Bag Hanging-Releasing/Clamping Device: Fixed at the cylinder bottom of the lifting mechanism. It adapts to packaging bags with a nominal volume of 1200~1400L. It supports manual suspension of straps and pneumatic clamping of the bag mouth during empty bag loading, and automatic bag mouth loosening and automatic strap unhooking during heavy bag unloading.
- Air Inflation/Return Air Dust Removal Pipeline: Synchronous dust removal during filling to suppress dust overflow.
- Steel Structure Frame: Made of stainless steel with sufficient strength and rigidity to fix the weighing platform of the entire packaging scale. Parts in contact with materials adopt 316L material.
III. Key Parameters

IV. Explosion-proof and Anti-oxidation Adaptation
According to material characteristics, Marchi provides customized explosion-proof services. Explosion-proof motors, explosion-proof control boxes and static grounding devices are optional, complying with ExdIIBT4 explosion-proof standards. For oxidation-prone materials, a nitrogen filling protection device can be installed to prevent material oxidation and deterioration.
V. Process Details
- Manual Bag Hanging: The operator hangs the straps of the empty jumbo bag on four hooks, sleeves the bag mouth over the discharging pipe, and presses the start button; the clamping device automatically clamps the bag mouth tightly.
- Automatic Lifting: The lifting mechanism rises to the preset filling height to ensure the bag is fully unfolded during material falling.
- Fast Feeding: The double-screw feeding mechanism operates at high speed to complete 90% of material filling, and the dust removal system starts simultaneously to suppress dust overflow.
- Precise Slow Feeding: When approaching the target weight, frequency conversion speed regulation switches to slow feeding to ensure the final accuracy.
- Lifting Compaction: During filling, the lifting mechanism vibrates the bag up and down 2-3 times to make the material compact and uniform.
- Automatic Unhooking: After weighing is completed, the clamping device loosens, the straps are automatically unhooked, the heavy bag drops to the pallet and is conveyed out by the conveying line.
