Core Configuration and Process Advantages
Marchi MCZD-25F fully automatic copper oxide packaging machine features high precision and high stability in core configuration. The weighing machine adopts a vertical screw feeding structure composed of a single screw, which is directly driven by a servo motor to ensure fast response and high-precision output in the metering process. During operation, the screw rotates to feed materials according to control signals, and the weighing sensor and weighing controller process weight signals in real time, synchronously outputting weight data display and control signals.
In the bag feeding section, the unit is equipped with core components such as a bag storage magazine, bag picking and arranging device, bag feeding manipulator, bag clamping and discharging device, bag holding and pushing device, bag mouth guiding device, vacuum system and control system. The whole bag feeding process includes bag picking from the storage magazine, bag centering and positioning, pre-opening of the bag mouth, manipulator inserting knife into the bag mouth, and air grippers on both sides clamping the bag mouth to complete stable bag feeding, effectively avoiding uncertainties and efficiency bottlenecks caused by manual operation.
Full Analysis of Packaging Process
The complete packaging process of Marchi fully automatic copper oxide packaging machine is: Feeding → Mixing → Lifting → Packaging → Sealing and Sewing → Weight Recheck → Metal Detection → Palletizing.
Specific process: After materials are fed from the upstream section into the equipment, they are evenly mixed and sent to the weighing system of the main packaging machine through the lifting mechanism. The metering system automatically completes filling according to the set packaging weight, followed by the automatic sealing and sewing process. Packaged products are conveyed to a weight recheck machine for weight verification, then pass through a metal detector to check for metal impurities. Qualified products enter the automatic boxing process, and finally palletizing is completed by a palletizing manipulator, forming a complete unmanned packaging production line from feeding to finished product warehousing.
Customized Explosion-proof and Anti-oxidation Adaptation
In response to the special needs of metal powder packaging, Marchi Packaging has specially designed explosion-proof and anti-oxidation measures in the equipment. For explosive powders such as copper oxide, aluminum powder and magnesium powder, the equipment can be equipped with an explosion-proof electrical control system and anti-static components to ensure safe operation in a dust environment. For easily oxidized high-value powders such as tungsten powder, titanium powder and molybdenum powder, the equipment supports nitrogen filling protection or vacuum packaging function, effectively isolating air through a closed packaging environment, controlling the oxidation rate at a low level and ensuring product quality. In addition, Marchi can customize degassing devices and dust-free packaging solutions according to material characteristics to meet the process needs of different powders.
Wide Adaptation to Diverse Materials
Marchi metal powder packaging machine has a wide application range, covering various metal powders such as aluminum powder, copper powder, copper oxide powder, copper hydroxide, aluminum hydroxide, iron powder, nickel powder, titanium powder, zinc powder, chromium powder, molybdenum powder, tungsten powder, lead powder, cobalt powder, tantalum powder, silver powder, gold powder, manganese powder, as well as tantalum-tungsten alloy powder, titanium alloy powder, molybdenum alloy powder, nickel alloy powder and copper alloy powder. In addition, the equipment can also be used for powder materials such as carbon black, graphite powder, gelatin powder, PVC powder, alkali powder, silica gel powder, calcium carbonate powder, mica powder, gypsum powder, iron ore powder, coal powder, talcum powder and ceramic powder, truly realizing multi-purpose in one machine.
Integration of Metal Detection, Boxing and Palletizing Production Line
To meet large-scale production needs, Marchi Packaging provides a complete integrated solution from the rear end of packaging to finished product warehousing, including processes such as weight recheck, metal detection, automatic case opening, automatic boxing, automatic case sealing and strapping and automatic palletizing. The metal detection process adopts a high-sensitivity metal detector to effectively reject products containing metal foreign matters and ensure factory quality; the palletizing process can be connected with a high-level palletizing manipulator or robot palletizing system to realize fully automatic palletizing and stacking, greatly reducing the intensity of manual handling.
Customer Pain Point Solutions
In the metal powder packaging process, enterprises generally face three major pain points:
Pain Point 1: Serious dust pollution and great pressure on environmental compliance.Copper oxide powder and various metal powders are prone to generate dust during packaging, which not only causes material loss but also brings the risk of dust explosion, as well as pressure from environmental protection inspections. Marchi fully automatic packaging machine adopts a closed filling structure with a negative pressure dust recovery device, suppressing dust overflow from the source and controlling the dust concentration in the working environment, helping enterprises pass environmental acceptance smoothly.
Pain Point 2: Insufficient metering accuracy and large loss of high-value materials.Some equipment has a metering error of more than 1%, and for high value-added metal powders, the long-term cumulative loss is considerable. Marchi equipment adopts a vertical screw feeding structure driven by a servo motor combined with a high-precision weighing sensor, with packaging accuracy stabilized at ≤±0.1～0.2%, which can control the error of 25 kg packaging within a very small range and effectively reduce material waste.
Pain Point 3: Low efficiency of manual packaging, difficult to match large-scale production.The traditional manual method of bag feeding, filling, sealing and palletizing is not only inefficient but also prone to operational errors. Marchi fully automatic packaging machine realizes full-process automatic operation, significantly increasing single-shift production capacity. Combined with the metal detection, boxing and palletizing production line, it can form a complete unmanned packaging production line, reducing labor costs while greatly improving production efficiency.
In view of the special hygroscopic and caking property of copper oxide powder, Marchi can also integrate a humidity control system and a closed material storage structure in the equipment to avoid moisture absorption of materials before packaging and ensure long-term storage stability of products.
Conclusion
As a leading domestic packaging equipment manufacturer, Guangzhou Marchi Packaging Equipment Co., Ltd. relies on 26 years of industry accumulation and continuous technological innovation to provide efficient, precise and reliable automated solutions for the metal powder packaging field. Whether for rare metal powders such as copper oxide powder and tungsten powder, or bulk powder materials such as iron powder and copper powder, Marchi MCZD-25F fully automatic powder big bag packaging machine can meet the personalized needs of various customers with stable performance and flexible customization capabilities, helping enterprises reduce costs, increase efficiency and realize intelligent upgrading.
