What are the precautions for installing the pearl cotton thermal bonding machine

The pearl cotton thermal bonding machine is typically used for the automatic and rapid adhesion of pearl cotton sheets. The equipment features two workstations—A and B—and is also known as an automatic dual-station gluing machine. The dual-station A-B worktables can operate independently or be easily interchanged, allowing one operator to manage both stations simultaneously.

At this point, some of our customers ask: "Your two workstations look exactly the same—during installation, couldn’t the left and right workstations be installed randomly? And would it still work if you reversed their positions?"

In fact, our bonding machine equipment undergoes debugging before leaving the factory—and only after passing inspection are they carefully packaged and shipped. During packaging, we disassemble the two workstations and pack them separately. When it’s time for installation, we clearly distinguish between the left and right workstations: the left workstation is installed on the left side, while the right workstation goes on the right side. Although the left and right workstations appear identical at first glance, they actually have different models, which means the programs in the touch screen are also tailored specifically for each one.

So, how can we distinguish the left and right workstations of the gluing machine? First, we need to understand the basic design principle of the gluing machine equipment. The AB workstations are designed so that one person can independently operate both stations simultaneously. As a result, the start buttons for each workstation are placed right next to each other—conveniently positioned for easy, single-person operation. However, if the AB workstations were accidentally installed backward, the start buttons would end up on opposite sides of the machine. In this scenario, it would become impossible for one person to manage and operate both stations effectively. This clear distinction makes it straightforward to identify which is the left workstation and which is the right one.

When distinguishing between the left and right workstations, immediately note the locations and wire numbers of the emergency stop switches and start switches (start buttons) on each workstation.

Left workbench: The red emergency stop switch has circuit numbers (L2, 10), while the green start switch is wired to (X10, 0V).

Right workbench: Red stop switch wires (l2 and 10), green start switch wires (x11 and 0V).

Next, let’s remember to securely plug in the power cords behind the workbench on both sides—this will properly connect the workbench to the electrical box.

The gas supply for the equipment is in good condition. We’re using a 0.3 MPa, 8 x 5.5 mm air hose as the gas source. (If the external air line differs in size from the one used on-site, please prepare an adapter in advance. Also, make sure to secure the air hose with wire clips.)

Ensure that an air switch with leakage protection is installed according to the bonding machine's capacity. It is recommended to use either a 125A/4P or 150A/4P air pressure switch—specifically designed for models ML-ZHJ-9060—with built-in leakage protection. For model ML-ZHJ-12080, a dedicated air control switch rated at 175A/4P or 150A/4P, also featuring leakage protection, should be employed. Always follow the manufacturer’s guidelines carefully, verifying that the correct main cable enterprise code is used for each connection. Failure to do so could result in damage to internal components of the equipment.

The machine’s main power cable has five wires: the black wire is the neutral line, labeled N; the greenish-blue wire represents the live phase AV 380V, labeled RST; and the yellow wire is the ground wire, marked PE. For connecting the machine to the air temperature switch, use the power cable routed along the floor and secure it with a cable tray.
