With the rapid development of new energy materials, coatings, rubber, plastics, cosmetics, ceramics, friction materials, metallurgy, insulating materials and other industries, mica powder, as an important functional powder material, its packaging automation level is directly related to production efficiency and product quality. Mica powder, sericite powder, phlogopite powder, muscovite powder, synthetic mica powder, wet-process mica powder, dry-process mica powder and mica powder for pearlescent pigments feature high insulation, layered structure prone to delamination, and great differences in fluidity of ultra-fine powder, putting forward stricter requirements on metering accuracy and dust prevention of packaging equipment.
As a powerful source manufacturer of packaging machine production lines, Guangzhou Marchi Packaging Equipment Co., Ltd. has 26 years of experience in the powder packaging industry. It launches the MCZD-25F fully automatic powder heavy bag packaging unit, with a service network covering major provinces and cities nationwide including Guangdong, Guangxi, Fujian, Jiangxi, Hunan, Hubei, Sichuan, Chongqing, Yunnan, Guizhou, Jiangsu, Zhejiang, Anhui, Shandong, Henan, Hebei, Shaanxi, Liaoning, Jilin and Heilongjiang. It provides a full-process automatic solution from metering and packaging to palletizing for mica powder products of various mesh grades from 300 mesh to 1250 mesh.
I. Industry Pain Points of Mica Powder Packaging
Mica powder packaging enterprises generally face the following problems in actual production: continuous rising labor costs, and 3 to 4 workers are required to cooperate to complete weighing, bagging and sewing in traditional semi-automatic packaging; difficult dust control, ultra-fine mica powder is easy to drift and raise dust, affecting the working environment and employee health; unstable metering accuracy, and fluctuations in material fluidity lead to large net content deviation of packaging; limited packaging efficiency, failing to match the front-end production capacity. In addition, the compatible switching of various bag materials such as woven bags, laminated kraft paper bags and plastic bags is also a common problem troubling many production lines.
II. Core Advantages of Marchi MCZD-25F Equipment
Model Selection
For powder materials such as mica powder, talc powder, calcium carbonate, barium sulfate, kaolin, titanium dioxide, quartz powder, wollastonite powder, barite powder, bentonite, pyrophyllite powder, dolomite powder, bauxite, magnesium hydroxide, aluminum hydroxide, antimony trioxide, dry mortar, pigments and dyes, food additives and feed additives, MCZD-25F adopts a single screw feeding mode, with a packaging weight range of 5 to 25 kilograms, meeting the demands of various finished product packaging specifications.
Core Configuration
The unit consists of a bag storage warehouse, 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 weighing machine adopts a vertical screw feeding structure with a single screw directly driven by a servo motor. The screw rotates for feeding according to control signals during operation, and the weighing sensor and weighing controller cooperate to complete signal processing and output weight data. The unit realizes a fully automatic process including bag picking from the bag storage warehouse, bag centering and positioning, forward bag conveying, bag mouth positioning, pre-opening, manipulator blade inserting into the bag mouth, and air grippers clamping both sides of the bag mouth to finish bag feeding.
Process Details: From Automatic Bag Feeding to Finished Product Palletizing
The packaging process realizes fully automatic continuous operation and can form a complete production line with supporting equipment until the final palletizing is completed.
Step 1: Automatic Bag Feeding and Filling
As the starting point of the whole production line, the packaging unit automatically picks bags from the bag storage warehouse. After bag arranging, centering and positioning, the manipulator completes bag feeding through precise actions of blade insertion and air gripper clamping. Mica powder falls into the packaging bag through the single screw feeding system. Driven by a servo motor, the metering speed and accuracy are guaranteed, with the packaging accuracy stably controlled within ±0.1%～0.2%. The fully enclosed dustproof structure effectively reduces environmental pollution and damage to electrical components caused by dust.
Step 2: Automatic Heat Sealing and Sewing
After filling, the packaging bag enters the integrated heat sealing and sewing process. The equipment is compatible with various materials such as laminated kraft paper bags, woven bags and plastic bags, and automatically completes bag mouth sealing without manual intervention.
Step 3: Bag Inversion and Conveying
The sealed material bag is pushed down by the bag inversion device and conveyed to the subsequent process, changing from vertical to flat state to facilitate subsequent shaping and palletizing.
Step 4: Weight Rechecking and Rejection
During conveying, the products pass through the weight rechecking system to recheck the net content of each finished bag. Material bags exceeding the allowable deviation range will be automatically rejected from the production line to ensure the metering qualification rate of finished products.
Step 5: Automatic Palletizing
Qualified bags enter the palletizing process. The production line can be equipped with a high-level palletizer or palletizing robot, which automatically stacks packaged bags on pallets according to preset parameters such as pallet type, layer number and quantity per layer. After palletizing, the pallets are transported away by forklifts or AGV trolleys, completing the full-process automatic operation from mica powder raw materials to stacked finished products.
The packaging speed reaches 1.5 to 2 bags per minute, with applicable bag length of 500 to 1000 mm. The whole system can be customized according to production capacity, material characteristics and site size, realizing unmanned operation of the whole process of "bag supply — bag feeding — weighing — filling — sealing — bag inversion — conveying — rechecking — rejection — palletizing".
