60 pieces/minute+0.1g precision control double breakthrough!SG-300Automatic weighing scaleCracking the bottleneck of high-speed quality control for small and medium-sized packaging
In the field of small and medium-sized packaging production, the high-speed line leakage rate of 60 pieces/minute of leisure food exceeds 5%, resulting in millions of after-sales losses, the 0.1g electronic component leakage causing terminal equipment downtime, and the frequent replacement of daily chemical samples resulting in a 40 minute delay in work. The imbalance of speed and accuracy, coupled with the three major pain points of "removing damage, inefficient replacement, and manual leakage", has become the core bottleneck restricting enterprises from improving quality and efficiency. Traditional weight inspection equipment either sacrifices accuracy for speed or reduces speed to maintain accuracy, but it still cannot meet the requirements of high-speed flexible production.

2、 Core System Architecture Decryption: Four Major Modules Build High Speed and Precise Barriers
SG-300 automatic weighing scaleThe core competitiveness of comes from the collaborative innovation of the four modules of "weighing execution control machinery", which fundamentally solves the accuracy and stability problems in high-speed scenarios:
2.1 millisecond level weighing detection module: precise capture of 0.1g in vibration environment
Adopting the core design of "dual sensor collaborative sampling", it is equipped with two C3 level sensors with a rated load of 5kg and a comprehensive accuracy of 0.01. Through the mechanism of "redundant acquisition+cross validation", the data error is reduced by 80% compared to the single sensor scheme, and the dynamic detection stability is improved by three times. Innovative research and development of intelligent dual-mode algorithm, which can automatically switch strategies according to production speed: high-speed noise reduction mode (40-60 pieces/min) real-time cancellation of 1-10m/min speed, 0-50Hz vibration interference, 3kg gift box detection accuracy stable at ± 0.2g, and missed detection rate reduced from 5% to 0.1%; The sampling frequency of high-precision mode (10-40 pieces/min) has been increased to 1000Hz, and the accuracy of 5g micro weight products can reach ± 0.1g. 0.1g micro leakage can be detected 100%. The sensor adopts IP67 fully sealed packaging and is equipped with a temperature compensation module with a wide temperature range of -10 ℃ -45 ℃. The 24-hour zero drift is ≤ 0.1g, which is suitable for food low-temperature workshops and electronic high-temperature soldering environments.
2.2 Adaptive sorting execution module: fully compatible with fragile/hard products without damage
Innovative design of the "air blowing+push board" dual-mode removal system, with a touch screen that can switch with just one click, solves the pain point of adapting to a single removal mode: the air blowing removal mode is specially customized for fragile items such as biscuits and potato chips, with an adjustable high-pressure pulse airflow of 0.4-0.7MPa and a response speed of ≤ 0.2 seconds. Non contact push avoids collision, and the damage rate has been reduced from 10% to 0.2% in a certain biscuit factory, reducing material loss by 150000 yuan per year; The push plate removal mode is suitable for hard products such as daily chemical bottles and hardware. It is driven by a 500N high-speed cylinder and equipped with a 3mm silicone buffer layer on the surface of the push plate to prevent product deformation. The removal accuracy is ≥ 99.9%. Equipped with dual photoelectric positioning devices, the first level photoelectric triggers the weighing timer, and the second level photoelectric confirms that the product is centered before performing rejection. During high-speed transportation, the product position deviation is ≤ 2mm, and the false rejection rate is ≤ 0.05%, far exceeding the industry average standard of 0.5%.
2.3 Intelligent Control Module: Efficient Guarantee for Multi Category Flexible Production
Equipped with an industrial grade ARM Cortex-A9 processor (with a processing speed of 1GHz), it achieves multitasking parallel processing without delay, accurately matching the production needs of "multiple categories and small batches": firstly, it can quickly switch production in 1 minute, with 80 sets of product parameter storage libraries built-in, covering weight standards, deviation ranges, exclusion modes and other information. When switching between 10g hand cream and 500g laundry detergent specifications in daily chemical factories, the debugging time is shortened from 5 minutes to 1 minute, and the production efficiency is improved by 80%; The second is full dimensional data traceability, supporting dual backup of 100000 pieces of testing data locally and in the cloud, recording product ID, weight values, testing time and other information. Excel reports can be exported by batch, improving the efficiency of electronic factory audits by 70%; The third is seamless integration of smart factories, equipped with RS485 interface (compatible with Modbus RTU protocol), real-time uploading of detection data to MES/ERP system, supporting remote parameter setting and status monitoring, achieving a fully automated closed-loop process of "detection storage traceability".
2.4 Anti vibration mechanical structure module: 60 pieces/minute, high-speed operation without precision hazards
Made of 1.2mm thick SUS304 stainless steel plate welded together, with 6mm reinforcement added to the load-bearing beam. The amplitude of the machine body during high-speed operation is ≤ 0.1mm, avoiding the impact of vibration on accuracy from the root. Equipped with food grade polyurethane conveyor belt and high-precision servo motor, the speed error is controlled within ± 0.1m/min, without slipping or deviation, and can achieve stable transportation of 3kg large packaging. The standard ground clearance height of the equipment is 750 ± 50mm, supporting customization within the range of 600-900mm. The height difference between the front and rear equipment is ≤ 5mm, and the gap is ≤ 10mm. There is no need to modify the existing production line, and installation, debugging, and production can be completed within 4 hours.
3、 Quick Production Guide: 4-hour closed-loop implementation, no need to modify the production line
3.1 Core requirements for installation environment
Site conditions: The installation ground has a flatness of ≤ 0.3mm/m, a load-bearing capacity of ≥ 300kg/㎡, and a reserved operating space of ≥ 1m around it, avoiding strong airflow and direct sunlight; Environmental parameters: working temperature -10 ℃ -45 ℃, relative humidity 30% -90% (no condensation), away from strong electromagnetic interference sources (such as large frequency converters and welding machines); Power configuration: 220V single-phase AC power supply, independent air switch (capacity ≥ 5A), voltage fluctuation within ± 10%, grounding resistance ≤ 4 Ω, recommended to be matched with a 500W voltage regulator; Gas path requirements: The air blowing removal mode requires clean compressed air of 0.6-0.8MPa, and a 5 μ m precision oil-water separator should be installed in the gas path.
3.2 Standard Debugging Process (4-hour closed-loop completion)
1. Horizontal calibration (40 minutes): Adjust the 4 foundation bolts with a 0.02mm/m precision level to ensure that the levelness of the machine body is ≤ 0.2mm/m (core premise); 2. Mechanical inspection (30 minutes): Manually test the conveyor belt for any jamming or deviation, conduct 10 empty load tests on the double removal mechanism, and confirm that the nozzle is not blocked and the buffer layer is not damaged; 3. Electrical self-test (20 minutes): There are no error codes such as E01 (sensor abnormality), E02 (conveyor belt fault) during the power on self-test, and the alarm light and touch screen display are normal; 4. Accuracy calibration (90 minutes): Use 10g, 100g, 1000g, and 3000g four level standard weights for multi-point calibration, and the system will automatically generate calibration curves (it is recommended to repeat once every quarter); 5. Load test (80 minutes): Use 10g, 500g, and 3000g standard parts to run continuously at a speed of 60 pieces/minute for 100 times, with an accuracy of ≤± 0.2g and a rejection accuracy of 100% before production.
Key reminder: The electronics industry needs to install anti-static rubber pads (with a resistance value of 10 ⁶ -10 ⁹ Ω); The food industry has adopted an oil proof cleaning mode for conveyor belts and conducts regular high-temperature disinfection.
