5-1500g full coverage! SG-220checkweigherOne machine adapted to multi scene quality control
In the food, daily chemical, and electronics industries, the three major pain points of "difficult adaptation, high loss, and slow production change" in quality control for small and medium-sized packaging include multiple specifications requiring multiple machines to occupy the workshop, a fragile product removal and damage rate of 8%, and a 10 minute production change and debugging. These factors have long pushed up enterprise costs. Traditional specialized weight inspection equipment either has a narrow range or a single elimination method, which cannot keep up with the pace of multi category production.

2、 Core System Architecture: Technical Barrier for Full Scene Adaptation
The competitiveness of SG-220 lies in the collaborative optimization of its four major modules, which fundamentally solves the pain points of quality control in small and medium-sized packaging:
2.1 Wide Range Precision Weighing Module: Stable Core with 0.1g Accuracy
Equipped with independently developed by Shanghai ZhijinC3 level high-precision resistance strain sensor(Rated load 2000g), combined with a 24 bit AD converter and 500Hz high-frequency sampling, achieves dynamic and accurate detection of 0.1g division value. The sensor is encapsulated with fully sealed epoxy resin (IP67 protection), which can withstand wet washing in food workshops and dust erosion in electronic workshops. The average time between failures (MTBF) reaches 12000 hours (50% higher than the industry).
Innovation IntegrationIntelligent range adaptation algorithmThe 5-50g light load section is sampled at 500Hz (with an accuracy of ± 0.1g), and the 50-1500g heavy load section is sampled at 300Hz (with an accuracy of ± 0.2g) to ensure consistent accuracy across the entire range. A certain electronics factory has measured that the identification rate of missing packages on a 5g chip tray is 100%.
2.2 Dual Mode Removal Module: Non destructive Adaptation for Fragile and Hard Products
Push board+flip board dual removal system with one click switching, targeted to solve the pain points of loss for different products:
Push board removalHigh speed rodless cylinder drive, thrust of 1000N, response time ≤ 0.3 seconds, suitable for hard products such as daily chemical bottles and hardware, front rubber buffer pad to avoid product scratches, accuracy rate ≥ 99.8%;
Flip board removalDriven by a servo motor, the angle can be infinitely adjusted from 0-90 °, allowing for slow flipping under light loads and stable flipping under heavy loads. It is suitable for fragile items such as cookies and chocolate, and the damage rate has been reduced from traditional 8% to below 0.3%.
Dual photoelectric alignment and positioning guarantee: When the product reaches the removal station, it will act synchronously, with a missed or incorrect removal rate of less than 0.05%, suitable for the rhythm of high-speed production lines.
2.3 Intelligent Control Module: Efficiency Engine for Rapid Production Change in 3 Minutes
7-inch touch screen equipped with industrial grade ARM processor, built-in50 sets of product parameter repositoryPreset weight standards, deviation thresholds, exclusion modes, and other parameters for products of different specifications, which can be easily retrieved and automatically calibrated with just one click during production changes. The production change time has been reduced from traditional 10 minutes to within 3 minutes. After being applied by a certain leisure food enterprise, the utilization rate of multi category production lines increased by 25%, and small batch customized orders for e-commerce were successfully undertaken.
Supports the cyclic storage of 100000 pieces of testing data, recording information such as testing time, product model, and qualification rate. Excel/CSV reports can be exported to meet the quality traceability and audit needs of the food and electronics industries.
2.4 Industrial grade mechanical structure: stable and durable adaptation cornerstone
The whole machine is made of SUS304 food grade stainless steel integrated molding, with a 1.2mm thick body and seamless welding by welding robots. Key parts are reinforced with reinforcing ribs, and the operating amplitude is ≤ 0.1mm, providing a stable foundation for high-precision detection. The 407mm × 220mm widened tabletop is matched with a diamond patterned food grade polyurethane conveyor belt (friction coefficient ≥ 0.7), which can prevent baking materials and electronic components from slipping during transportation and is suitable for irregular packaging.
