Daily maintenance checklist for book and magazine gluing machine: What are the tubes for gluing pot, conveying, milling back, and pressing books

The glue machine is not just about cleaning the glue pot.The daily maintenance of the whole machine (glue pot+conveying+milling back+pressing book+clamping+electrical) determines whether the bonding is stable or not, and whether there are many pages falling off. Many factories equate maintenance with “cleaning the glue pot”, but as a result, the conveyor belt runs off track, the milling back blade becomes dull and no one takes care of it, and the pages still fall off and the glue is exposed. Here is a daily/weekly/monthly maintenance checklist.

1、 Why maintenance is more important than repair

A crucial phrase in the industry is:90% of after-sales service is due to equipment temperature control failure——Temperature control, conveying, and pressure are not accurate, and even if the glue is good, the pages will fall off. The device status directly determines the bonding result:

• The stability of imported glue assembly machines is usually better than that of domestic ones (based on common equipment experience), but even the best machines will float without maintenance;
• Temperature, pressure, and alignment parameters change every day, and relying on ‘last adjustment’ is unreliable. Daily inspections are necessary.

2、 Daily maintenance checklist of 6 items

1. Glue potBefore class starts, calibrate the actual temperature with a thermometer (don’t just look at the panel, see method for details)What should I do if the temperature of the glue pot is not accurate? Calibrate with a thermometer）Long term insulation should take the middle and lower limits; Regularly clean carbon, replace rubber and clean machine (seeHow to clean the glue pot when changing glue or wire）；
2. Conveyor belt/book clamp mechanismCheck the tension, alignment, and cleanliness, and ensure that there is no deviation, no books falling off, and no glue rubbing;
3. Milling back cutterCheck sharpness, even milling depth (affecting adhesive penetration, coordination)To what extent is it best to make the back of a book hairyWatch together);
4. Hair pulling/plucking mechanismThe brush state and surface roughness are uniform, neither excessive nor light;
5. Press book organization: Uniform pressure, sufficient pressing time, no rebound of spine (see complete process for details)Complete steps for book and magazine adhesive packaging）；
6. Electrical/LubricationRegularly lubricate the guide rail, clean the sensors and photoelectric eyes to avoid misjudgment.

This article only focuses on the glue pot part and does not elaborate on it – there is already a dedicated article on carbon cleaning, machine cleaning, and poor glue supply（How to troubleshoot if the glue pot cannot produce glue or if the glue supply is not smooth）Repeating writing can lead to internal competition within the site, and it can be linked to the site when needed.

3、 The 3 most easily overlooked places outside of the glue pot

• Conveyor belt deviation → Uneven book core → Exposed glue, uneven book back;
• Blunt milling back blade → Uneven pulling and poor penetration → Page dropping and glue cracking;
• Uneven pressure on books The spine rebounds and the incision is uneven.

These three points are not in the glue pot, but directly determine the quality of the book back, which is the most easily overlooked maintenance point for “cleaning only the glue pot”.

4、 Suggestions for maintenance rhythm

• Daily (before class starts)Calibrate the temperature of the glue pot with a temperature measuring gun, perform quick spot checks for conveying, clamping, and pressing, and clean the surface of the glue pot for crust formation;
• weeklyCheck the sharpness of the milling back blade, the condition of the brush, and the pressure of the press;
• monthlyLubrication of guide rails, cleaning of electrical and sensor systems, and overall fastening and alignment of each mechanism.

Making a checklist for inspections is much more stable than just checking when you remember.
