How To Debug Sandwich Panel Machine

There may be differences in the models of different sandwich panel machines. It is recommended to refer to the equipment manual or contact the manufacturer for targeted guidance.

Preparation work before debugging

• Equipment inspection
  Ensure that the machine is placed horizontally, adjust the casters to evenly distribute force on all four feet, and avoid vibration or displacement during operation.
  Check the power connection (220V voltage) and grounding safety, and confirm that there are no exposed wires or poor contacts.

• Preheating and preparation of rubber material
  Turn on the power switch, heat the glue tank to the set temperature (usually 95 ℃), and wait for the glue to completely melt (about 20 minutes).
  The liquid level of the adhesive should be kept at the center of the rubber wheel shaft to avoid excessive or insufficient influence on the uniformity of the adhesive application.

Core parameter debugging

• Clamping pressure and time
  Thin plate debugging: Increase the clamping pressure (within the range of 30-100kg) and shorten the clamping time (recommended 1-4 seconds).
  Thick plate debugging: Reduce cover pressure, extend clamping time (6-10 seconds), and prevent wrinkling of the spine.

• Adjustment of glue amount
  Insufficient glue amount: Rotate the scraping knob to the right to increase the glue amount; If the adhesive solution in the groove is insufficient, it needs to be replenished.
  Excessive glue amount: Adjust the knob to the left to reduce the glue amount and avoid overflow of edge glue or wrinkles on the spine of the book.

• Thickness and temperature matching
  Adjust the temperature of the glue tank according to the thickness of the board to ensure the fluidity of the glue solution (slightly lower for thin boards and slightly higher for thick boards).
  If the thickness of the adhesive is uneven, it is necessary to check the temperature stability or extend the preheating time.

Operation mode selection

• Manual mode
  Suitable for special sizes or materials (such as financial documents, old books):
  Align the book to the left on this table → clamp → place the cover → start → reset the platform and remove the finished product.

• Automatic mode
  When used in mass production, it is necessary to first calibrate the thickness and cover center position through manual mode, and then switch to automatic loop binding.

Common problem handling

• Poor adhesion of spine: Check if the glue is insufficient or if the glue has not completely melted, adjust the scraping knob or extend the preheating.
  

• Cover bending and dragging: Check if the clamping pressure is balanced, adjust the left and right clamping surface pressure to symmetry.
  

• Equipment deviation: Check if the roller slips or if there are foreign objects on the guide rail, clean and recalibrate the level.

Safety and Maintenance

• Shutdown maintenance: Do not turn off the power for a long time to avoid aging of the adhesive solution.
  

• Cooling treatment: Finished products need to be stacked and stacked until completely cooled before cutting to prevent the inner pages from scattering.
