The debugging and acceptance of automatic paper tube making machine are key links to ensure stable operation of equipment and product quality, and must be strictly implemented in accordance with technical specifications.

First、 Preparation before debugging

Equipment inspection: Confirm that mechanical components (such as pipe rollers, cutting knives, glue systems, drive belts, etc.) are securely installed without looseness or misalignment. Check if the lubrication system (guide rails, bearings, gears) has been filled with specified lubricating oil (such as ISO VG68 industrial gear oil). The electrical circuit is not exposed, the grounding resistance is ≤ 4 Ω, and the shielding of the servo motor coding line is intact.

Material and parameter settings: Prepare the raw paper (with a weight and width that meets the process requirements) and adhesive (with a viscosity typically ranging from 500-1500 CPS) for testing. Enter process parameters (paper tube diameter, wall thickness, winding angle, cutting length, etc.) to ensure consistency with the design drawings.

Second、 Staged debugging process

1. No load debugging

Operation test: Start the Kraft paper core making machine at low speed (10-15% rated speed) and observe whether each transmission component (such as spindle, belt, chain) runs smoothly without abnormal vibration or noise (≤ 75dB). Check whether the pressure of the pneumatic system (if applicable) is stable (0.5-0.7MPa) and whether the cylinder action is synchronized.

Electrical testing: Verify the PLC program logic to ensure that automatic paper feeding, gluing, winding, cutting, and other actions are executed in a timely manner. Test emergency stop button, safety grating and other protective devices, with a response time of ≤ 0.5 seconds.

2. Load debugging

Preliminary trial production: Run at 30% rated speed, observe whether the tension of the raw paper is uniform (tension controller fluctuation ≤ 5%), and whether the glue coating covers more than 90% of the width of the paper web. Check the concentricity of the initial roll of the paper tube (radial runout ≤ 0.2mm/m), with no bubbles or delamination.

Gradually increase speed: Increase the speed by 10% every 20 minutes, and continue running for 1 hour until reaching 80% of the rated speed. Monitor the motor current (not exceeding the rated value) and bearing temperature (≤ 70 ℃).

3. Precision debugging

Winding accuracy: Use a dial gauge to measure the deviation of the outer diameter of the paper tube (± 0.1mm), adjust the pressure of the winding roller or the tension of the base paper.

Cutting accuracy: The cutting length error is ≤± 0.5mm (if cutting a 1000mm paper tube, the actual measurement should be between 999.5-1000.5mm), adjust the servo knife position or encoder parameters.

Concentricity calibration: Conduct a rolling test on the finished paper tube, requiring no jumping and an end face flatness of ≤ 0.2mm.

Third、 Acceptance criteria

performance index

Production efficiency: Achieve the design speed (such as a diameter of 50mm paper tube ≥ 60 meters/minute) and run continuously for 4 hours without any faults.

Finished product qualification rate: Randomly select 50 paper tubes, with a qualification rate of ≥ 98% (no defects such as glue opening, deformation, length deviation, etc.).

Quality Inspection

Physical properties: compressive strength (e.g. for paper tubes with a diameter of 50mm ≥ 800N/100mm, tested according to GB/T 2679.8). Moisture content ≤ 10% (detected using a moisture analyzer).

Appearance quality: The surface is smooth without wrinkles, the seams overlap evenly (± 1mm), and the incision is free of burrs.

Safety and stability: The triggering rate of automatic 4 heads spiral paper core making machine protection devices (overload, paper breakage, insufficient glue alarm, etc.) is 100%. Continuous production for 8 hours, with temperature rise of key components (motor, reducer) ≤ 40 ℃.

After acceptance, a trial production period of 1-2 weeks will be reserved for on-site observation by the supplier’s technical personnel. It is recommended to check the fastening status of transmission components once a week in the first month to prevent looseness from affecting accuracy.
