The powder automatic packaging machine is a key terminal equipment for
large-scale quartz sand production lines (daily processing capacity ≥ 3000t) to
deliver finished products. It is responsible for accurately measuring and
sealing high-purity quartz sand powder (particle size 0.074-0.4mm) for packaging
(with measurement error ≤ ± 0.2%, no powder leakage pollution, and packaging
efficiency ≥ 200 bags/hour), directly determining the factory qualification
rate, transportation loss, and brand reputation of finished products. Currently,
many enterprises are facing problems such as large measurement deviations,
powder leakage and dust, and delayed packaging speed, resulting in high rework
rates, numerous environmental complaints, and long delivery cycles. As a strong
manufacturer of equipment covering the entire process of quartz sand crushing,
purification, environmental protection, and packaging, Shandong Heavy Industry
has more than 10 years of experience in customizing powder packaging equipment.
Equipped with a professional mechanical design and intelligent control R&D
team, it can provide integrated services from equipment selection, structural
customization to installation and commissioning, and after-sales operation and
maintenance. It has helped dozens of quartz sand enterprises across the country
achieve efficient and clean production of finished products.
1、 Attribution of Core Pain Points: Three Core Problems in the Operation of
Packaging Machines
Based on the practical experience of the on-site technical service team of
Shanlu Heavy Industry, the root causes of the problems with the quartz sand
powder packaging machine are concentrated in three points: firstly, poor
adaptability of the measuring system, strong fluidity of quartz sand powder,
easy bridging, and lagging response of traditional measuring devices, resulting
in a weight deviation of more than ± 0.5% per bag; Secondly, the sealing
structure is unreasonable, with inadequate sealing at the connection between the
feed inlet, discharge outlet, and bag opening, resulting in powder leakage and
dust, which does not meet environmental protection requirements; The third issue
is insufficient coordination between transportation and packaging, uneven powder
feeding, and deviation in bag opening positioning, resulting in delayed
packaging speed and inability to meet high-yield demands. These issues not only
affect factory efficiency, but also increase material loss and environmental
remediation costs.
2、 Shanlu Heavy Industry Adaptation Empowerment: The Core Advantage of
Customized Solutions
Unlike industry standard packaging equipment, Shanlu Heavy Industry always
adheres to the concept of "end to end adaptation, customized adaptation needs",
and tailors packaging machine optimization solutions based on the
characteristics of quartz sand powder, enterprise production capacity, and
packaging specifications (25kg/bag, 50kg/bag). Relying on the company's
standardized production base and intelligent control technology reserves, Shanlu
Heavy Industry's powder packaging equipment can achieve full process
collaboration in metering, sealing, conveying, and palletizing, while also
equipped with remote monitoring and fault warning functions, significantly
reducing manual operation and maintenance costs. In addition, Shanlu Heavy
Industry promises a one-year equipment warranty and lifetime technical upgrades
and spare parts supply services to ensure the long-term stable operation of the
equipment and solve the company's subsequent maintenance concerns.
3、 Step by step optimization plan: Three dimensions to solve packaging
problems
1. Measurement system upgrade: precise adaptation to powder
characteristics
In response to the pain point of inaccurate measurement, Shanlu Heavy
Industry has customized and optimized the measurement core module: using a
"weighing sensor+variable frequency feeding" dual control system, the sensor
accuracy reaches 0.1g, real-time feedback of weight data, and the variable
frequency feeder dynamically adjusts the feeding speed according to the data to
achieve "fast supply+slow replenishment" precise measurement, with stable error
within ± 0.2%; Install a high-frequency vibration arch breaking device in the
feeding bin, combined with a spiral flow guiding structure, to solve the
problems of powder bridging and uneven feeding, ensuring the continuity of
measurement; Equipped with automatic calibration function, it automatically
calibrates the measurement accuracy upon daily startup to avoid long-term
operational deviations.
2. Customized sealing structure: environmentally friendly and leak free
powder
The core of powder leakage and dust is inadequate sealing connection. Shanlu
Heavy Industry optimization plan: The feed inlet adopts a dual structure of
"flexible sealing+negative pressure adsorption", which conforms to the flow
trajectory of the powder and prevents dust during feeding; Install a
polyurethane sealing sleeve at the junction between the discharge port and the
bag mouth, equipped with an automatic clamping device, to tightly fit without
gaps during packaging; The whole machine is equipped with a small pulse dust
removal device to adsorb the leaked fine powder, which is environmentally
friendly and can recycle materials, reducing losses. The sealing structure has
passed environmental testing and fully complies with the environmental emission
standards for quartz sand production.
3. Collaborative system optimization: improving packaging efficiency
In response to the problem of lagging packaging speed, Shandong Heavy
Industry has achieved full coordination between conveying and packaging:
equipped with a variable frequency powder conveyor, accurately matching the
feeding requirements of the packaging machine to avoid insufficient or
overloaded feeding; Optimize the bag opening positioning system, using a dual
guarantee of photoelectric induction and mechanical positioning, with a bag
opening positioning deviation of ≤ 2mm, reducing bag replacement time; For
high-yield production lines, multi station packaging machines can be customized
to achieve synchronous packaging of 2-3 bags, increasing packaging efficiency to
over 250 bags/hour and meeting the factory requirements of 3000t/d production
lines.
4、 Implementation effectiveness and service guarantee
A certain high-purity quartz sand enterprise with a daily output of 3200t had
frequent environmental complaints due to the large measurement deviation and
serious powder leakage of traditional packaging machines, resulting in a rework
rate of over 8%. After adopting Shanlu Heavy Industry's customized powder
packaging machine solution, the measurement error stabilized at ± 0.15%, the
powder leakage problem was completely solved, the packaging efficiency was
improved to 220 bags/hour, the rework rate was reduced to below 1%, and the
annual material loss and environmental improvement costs were saved by more than
500000 yuan.
