Precautions for using paper edge protector machine

The precautions for using Paper edge protector machines (paper corner protection production lines) are key to ensuring safe production, stable operation, and product quality.

Preparation and inspection precautions before production

Equipment status check:

Before starting up the equipment every day, a routine inspection must be carried out, including whether each transmission component (such as belts, chains, gears) is loose, whether the lubrication is good, and whether the air and electrical circuits are normal.

Check whether the cutting tools (slitting blades, trimming blades) are sharp, firmly installed, and whether they are damaged or curled. Blunt knives can cause uneven incisions, burrs, and accelerate equipment wear.

Check the glue system: whether the amount of glue in the glue box is sufficient, whether the rubber hose is unobstructed, whether the glue roller or spray nozzle is clean and unobstructed.

Raw material confirmation:

Check whether the weight, width, and moisture content of the raw paper (kraft paper) meet the process requirements. Paper that is too damp or too dry can affect its forming and bonding strength.

Check if the original paper roll of the paper angle edge board machine is placed correctly to avoid deviation during operation.

Parameter presetting and calibration:

According to the order specifications (corner guard length, width, thickness), accurately adjust mechanical parameters such as cutting size, indentation position, and forming angle.

Calibration coating amount: Excessive coating can cause overflow, waste, and slow drying; Too little will result in weak adhesion. Adjustments need to be made according to the type of paper and adhesive.

Conduct a no-load trial run, observe whether the actions of each workstation are coordinated, and confirm that there are no errors before feeding.

Precautions for operation during the production process

Standardize feeding and paper guiding:

Ensure that the center is aligned and securely fastened when feeding the paper roll. The paper guiding process should be smooth to prevent the paper from tearing or being rolled into the wrong position.

During equipment operation, it is strictly prohibited to touch dangerous moving parts such as forming rollers, pressing rollers, and cutting tools with hands or tools.

Closely monitor the operational status:

Focus on the bonding effect: observe whether the glue is evenly and continuously applied, whether the formed corner joint is tight and straight, and whether there is no glue cracking or bubble phenomenon.

Monitoring dimensional stability: Regularly inspect the length, angle, and straightness of corner protectors to prevent dimensional drift caused by mechanical looseness or belt slippage.

Listen to the sound and identify the position: Pay attention to the sound of equipment operation. If there is abnormal friction, impact sound or increased vibration, stop the paper corner protector production line immediately for inspection.

Glue and temperature management:

Keep the working temperature of the glue constant (if heating is required). Temperature changes can significantly affect the viscosity and bonding performance of adhesives.

Prevent glue from solidifying in the system. If the downtime is long, the rubber road needs to be cleaned according to the prescribed process.

Material and finished product processing:

Timely clean up the paper scraps and waste generated by cutting and trimming, to prevent accumulation that affects equipment heat dissipation, gets involved in transmission parts, or causes fires.

Finished products should be stacked neatly to avoid deformation of newly formed hot corner protectors (if using hot melt adhesive) due to compression.
