Packaging machinery and equipment quality appraisal

packaging machinery and equipment is based on the core principle of automated packaging and precise control synergy. By optimizing packaging speed, positioning accuracy and sealing strength, it achieves synergy of product packaging sealing, appearance consistency and production efficiency. It is widely used in automated production lines of food, medicine, daily chemicals and electronic products. In the food industry, it is used to control the oxygen residual amount in vacuum packaging; in the medical field, it meets the punching accuracy of blister packaging; in electronic products, it ensures the reliability of anti-static packaging. Compared with traditional equipment, packaging machinery and equipment have the characteristics of multi-axis synchronous control (servo drive + visual correction), intelligent diagnosis and flexible adaptation, and are the core equipment of modern production lines.

Zhongke Testing is a product quality appraisal service organization registered with the court. It can provide quality appraisal services for packaging machinery and equipment. It has a professional appraisal team and advanced instruments and equipment to provide fair and accurate appraisal results for the quality appraisal of packaging machinery and equipment.

As the complexity of packaging processes increases, related quality dispute cases have increased significantly. The judicial dispute focuses on:

1. Dispute over performance indicators: packaging speed is not up to standard and sealing strength is insufficient;

2. Material defects: heat sealing film coating has poor temperature resistance and conveyor belt wear resistance life;

3, process problems: servo positioning accuracy deviation, vacuum pump pumping speed attenuation;

4, contract performance dispute: core modules (such as imported servo motors, high-precision vision systems) are inconsistent with the technical agreement.

Litigation quality appraisal of packaging machinery and equipment mainly includes the following technical methods:

1, Appearance inspection method

By directly observing the appearance of the equipment, check whether there are obvious defects in the equipment, such as damage, deformation, corrosion, etc. of parts. Appearance inspection can initially determine the overall condition of the equipment and provide clues for further identification.

2, performance testing method

conduct actual tests on various performance indicators of the equipment in accordance with the requirements of relevant standards and technical contracts. Performance testing can use professional testing equipment and instruments to ensure the accuracy and reliability of test results. Through performance testing, you can objectively evaluate whether the actual performance of the equipment meets the requirements.

A food factory of the applicant signed a "Purchase Contract for Fully Automatic Vacuum Packaging Machine" with an equipment manufacturer of the respondent, and the agreed speed is ≥500 pieces/minute. After being put into production, the actual output was only 300 pieces/minute. The manufacturer argued that it was due to the difference in product size.

identification analysis results:

The quality analysis expert group discussed and synthesized technical data on "packaging machinery and equipment" related information, contract technical agreements, on-site inspection case materials and other data After analysis, the following quality analysis opinions were made:

The servo motor torque of the packaging machinery involved in the case fluctuated by ±20% (agreed ±5%), and the vacuum pump pumping speed was only 65% of the agreed value; the heat sealing film had insufficient temperature resistance (bubble temperature 140°C), resulting in frequent shutdown adjustments.

The appraisal conclusion determined that defects in the power system and materials were the main causes of insufficient efficiency.

Packaging machinery and equipment quality appraisal report should include:

1, appraisal purpose (such as production loss attribution, contract compliance verification) and reference standards;

2, involved equipment model, control system version, production log;

3, detection method and equipment list (Such as laser speedometer, universal testing machine);

4, correlation analysis between test data and failure (such as the impact of servo torque fluctuation on speed);
