This standard applies to square-bottom paper bag making machines, both with and without handles , and covers equipment with different handle types, including round rope and flat rope. This means the standard takes into account the mainstream roll paper bag making machine types on the market, making it widely applicable.

In terms of technical parameters, the standard has made quantitative provisions for indicators such as production efficiency, finished product quality, and equipment stability of roll square bottom paper bag machines.

Compared with sheet-fed paper bag machines, roll-fed square bottom paper bag machines have unique technical requirements in terms of unwinding mechanism, tension control, and continuous forming . Standards have corresponding regulations for these special aspects.

The standard also pays special attention to the safety performance of the equipment, and puts forward clear requirements for transmission protection, electrical safety, and emergency shutdown to ensure the safety of operators during high-speed operation.

Key points for paper bag machine testing and compliance assessment

Testing paper bag machines is a crucial step in ensuring that the equipment meets standard requirements. According to relevant standards and technical requirements, the testing of paper bag machines mainly includes several aspects such as mechanical structural stability, heat sealing system performance, motion control system accuracy, and electrical safety indicators.

Mechanical structure stability testing includes the tensile strength of welded points (≥350MPa), axial runout of the transmission system (≤0.02mm), and frame verticality error (≤1.5mm/m).

These indicators are directly related to the long-term stability and reliability of the equipment.

The performance testing of the heat sealing system mainly includes temperature control accuracy (required to be ±1.5℃), pressure uniformity (≥0.4MPa in more than 85% of the area), and seal peel strength (required to be ≥3.5N/15mm).

These parameters directly affect the sealing quality and yield of paper bags.

The motion control system testing involves servo motor positioning accuracy (required ±0.05mm), feeding synchronization error (required ≤0.3ms), and emergency stop response time (required ≤0.5s), etc.

These indicators are related to the production accuracy and safety of the equipment.

Electrical safety testing includes insulation resistance (≥100MΩ), grounding continuity (≤0.1Ω), and electromagnetic compatibility. These tests are fundamental requirements for ensuring the safe operation of equipment.

For businesses, determining whether equipment meets standard requirements involves first verifying whether the equipment's technical parameters are consistent with the standard requirements , then reviewing whether the equipment's test report is complete , and finally verifying the equipment's actual performance through trial operation.
