What are the maintenance methods for bag-making machines, and what specific content do they entail? Next, Zunlei Machinery, a bag-making machine manufacturer, will introduce these to you.

Maintenance Rule: After the first half-month of purchasing a bag-making machine, it is necessary to oil all shaft sleeves every 2 hours. After the first half-month, oiling all shaft sleeves every 4 hours is sufficient.

1. It is necessary to clean all the debris from the rollers on the bag-making machine after each shift to ensure a smooth process for the machine.

2. Tighten the chain every 15 days to an appropriate tension.

How to handle the issue of incomplete sealing on bag-making machines?

LDPE generally offers moderate anti-fouling heat-seal properties, while EVA boasts better anti-fouling heat-seal properties when the VA content is high. LDPE also exhibits good anti-fouling heat-seal properties, with ionic resins and metallocene polymers having superior anti-fouling heat-seal characteristics.

All gears on the bag-making machine should be tightened every 3 days to prevent loosening.

How to Deal with Bag Sealing Machine's Brittle and Cracking Seals?

Let's break down the elements contributing to such uncertainties: ① It could be due to excessive pressure; ② extended heat sealing time; ③ During the lamination and curing process, some adhesive has渗入film interior; ④ After cooling and storage, the heat-seal strength of the composite packaging bag has increased, but there is also a tendency towards becoming brittle.

All pressure plate screws should be tightened every 6 days to prevent loosening. The pressure plates are located at the parallel large plate of the grape bag machine.

Should such a question arise, our solution is:

Based on the heat-sealing characteristics of the inner layer material, select the appropriate processing temperature, pressure, and heat-sealing time.

Enhanced the surface condition of the upper heat sealing blade, ensuring a smooth surface for the sealer.

This is a common question we encounter during our regular production. Of course, we need to pay more attention to equipment maintenance to reduce issues during the production process.
