I. Model Selection: Customized Design for Carbon Black Powder
Carbon black, silica and pigment carbon black share common characteristics such as ultra-fine particle size, low bulk density, easy dust flying and static electricity generation. Traditional manual packaging not only brings high labor intensity, but also causes potential safety hazards including dust explosion and environmental pollution. Marchi Packaging Equipment provides customized model configurations according to differentiated properties of the three materials.
- Carbon Black Packaging Machine: Suitable for conventional industrial carbon black such as rubber reinforcing carbon black, conductive carbon black and acetylene carbon black.
- Silica Packaging Machine: Specially designed for fumed silica, precipitated silica, hydrophobic silica and hydrophilic silica. Equipped with degassing device to solve high gas content problem.
- Pigment Carbon Black Packaging Machine: Applied to high pigment carbon black and superfine pigment carbon black used in ink and coating industries. Vacuum packaging function is available to ensure pure and pollution-free powder.
All three models adopt Marchi MCSJ-LLB-25K fully automatic 25kg powder packaging machine as core equipment. It can operate independently or form complete powder packaging lines with upstream and downstream devices, meeting packaging demands of heavy calcium carbonate, light calcium carbonate, talc powder, titanium dioxide, kaolin, precipitated barium sulfate, silica powder, graphite powder, lithium iron phosphate and other chemical powders.
II. Core Configuration and Key Parameters
The core technical advantages of Marchi packaging machine are reflected in the following aspects.
Feeding and Metering System: The weighing machine adopts vertical single screw feeding structure directly driven by servo motor. The screw rotates and feeds materials precisely according to control signals. Weighing sensors and controllers process weight signals in real time to display weight data and output control signals, with packaging accuracy controlled within ≤±0.1%～0.2%. Compared with traditional pneumatic control, servo motor drive features fast speed, stable operation, no impact and long service life.
Automatic Bag Loading System: The unit consists of bag storage bin, bag taking and sorting device, bag loading manipulator, bag clamping and discharging device, bag pushing device, bag mouth guiding device, vacuum system and control system. The bag loading procedure includes bag taking, centering positioning, forward conveying, bag mouth positioning, pre-opening, cutter insertion and bilateral pneumatic clamping. The bag picking and loading mode has low requirements on bag dimensional error and quality, effectively reducing bag making cost. The servo-driven bag loading manipulator ensures stable and impact-free operation.
Sealing and Dustproof Design: Pneumatic components such as solenoid valves are hermetically installed instead of exposed layout, adapting to high-dust environment and guaranteeing long-term stable operation in carbon black workshops.
Key Parameters
- Equipment Model: Fully Automatic 25kg Powder Packaging Machine (MCSJ-LLB-25K)
- Packaging Weight: 5～25 kilograms
- Packaging Accuracy: ≤±0.1～0.2%
- Packaging Speed: 1.5～2 bags per minute
- Bag Size: Length 500～1000 millimeters
- Applicable Bag Material: Kraft paper laminated bag, coated woven bag, plastic bag (film thickness 0.2mm), woven bag with inner PE plastic bag, etc.
III. Complete Packaging Process Analysis
Marchi carbon black packaging production line realizes full-process automation from feeding to finished product warehousing. The detailed procedures are as follows.
Step 1: Feeding and Mixing. Carbon black, silica or pigment carbon black powder enters the system through feeding ports and gets evenly mixed for subsequent metering.
Step 2: Lifting and Screw Metering. Powder is delivered to the metering station by lifting mechanism. The vertical single screw driven by servo motor feeds materials accurately. Weighing sensors feed back weight data in real time, and two-stage feeding control of fast rough feeding and slow fine feeding is automatically completed to ensure qualified net content of each bag.
Step 3: Automatic Packaging. The machine finishes a series of actions including bag taking, sorting, loading, pre-opening, clamping discharging and pushing without manual intervention.
Step 4: Sealing and Stitching. Integrated thermal sealing and stitching are automatically carried out after feeding. Tightly sealed bag mouths effectively prevent powder leakage and moisture absorption.
Step 5: Weight and Metal Detection. Finished products are rechecked by weight detectors, and unqualified goods are automatically rejected. Metal detectors avoid foreign matter mixing to guarantee product quality.
Step 6: Robot Palletizing. Qualified bags are transported to palletizing stations. Marchi palletizing robots stack goods neatly in preset patterns with maximum stacking height of 2400mm, compatible with various pallet specifications. Winding film packaging can be equipped for reinforcement to facilitate storage and transportation.
Step 7: Warehousing. Reinforced palletized goods are sent to storage area via conveyor lines to finish the whole production process.
IV. Equipment Application Scenarios
Marchi carbon black packaging machines are widely applied in various industries.
- Rubber and Tire Industry: As important reinforcing filler for tire tread, sidewall and sealing parts, carbon black requires accurate metering and packaging. The equipment operates stably under high-dust conditions.
- Coating and Ink Industry: High purity standard is required for pigment carbon black used as black pigment. Vacuum packaging avoids product contamination.
- Plastic and Masterbatch Industry: Carbon black serving as colorant needs precise proportioning and packaging with carrier resin such as polyethylene and polypropylene.
- Battery and New Energy Material Industry: Strict dust control is required during packaging of silica used as lithium battery diaphragm coating material.
The equipment is also applicable to graphite, calcium carbonate, lithium iron phosphate, ternary material, aluminum hydroxide and other powder materials.
V. Customer Pain Points and Solutions
Pain Point 1: Severe dust emission causing workshop pollution and environmental inspection pressure
Solution: Adopt fully sealed structure equipped with dust removal interfaces connectable to central dust removal system. Practical data from tire manufacturers shows workshop dust concentration drops to ≤8mg per cubic meter, meeting national environmental standards. Internal components are sealed installed to prevent dust damage to electrical systems.
Pain Point 2: Unstable packaging accuracy leading to obvious batch weight difference and low customer satisfaction
Solution: High-precision weighing sensors and servo-driven screw feeding system stabilize packaging accuracy within ≤±0.1%～0.2%. Two-stage feeding strategy ensures highly consistent net content of finished products.
Pain Point 3: Poor bag compatibility, high bag making cost and difficult specification switching
Solution: The bag picking mode tolerates bag dimensional errors. It fits multiple bag types with adjustable length ranging from 500mm to 1000mm. Frequent mold replacement is unnecessary, cutting down bag making and production switching cost.
Pain Point 4: Low manual bag loading efficiency, high labor intensity and staffing difficulties
Solution: Full-automatic bag loading system realizes unmanned operation from bag taking to filling and sealing. One machine can replace 3 to 5 workers and reduce long-term labor cost.
Pain Point 5: Static electricity generation of carbon black bringing explosion risk
Solution: Complete grounding system and static elimination devices are equipped. Pneumatic and electrical parts are anti-static treated to ensure safe operation in flammable and explosive environment.
