What are the current models of Oushida's gear pump hot melt adhesive dispensers?

The operating principle of a gear pump hot melt adhesive dispenser is to achieve a stable supply of adhesive through the precise transmission of a gear pump. The hot melt adhesive is heated to a set temperature within the barrel, gradually transforming from a solid to a fluid liquid. A heating rod and temperature sensor within the barrel maintain a stable adhesive temperature in real time, preventing carbonization due to overheating or poor fluidity caused by insufficient temperature. When the adhesive reaches the preset fluidity, the gear pump begins operation, eliminating the instability of traditional gravity feeders and maintaining a consistent output even with varying viscosity.

1. The melting cylinder is welded from alloy aluminum, precision-machined, and coated with DuPont Teflon, resulting in a strong, non-flaking coating. This significantly reduces carbonization of the hot melt adhesive, and the melting cylinder utilizes a progressive heating design.

2. The motor and gear pump are connected by a specially designed synchronous coupling, offering high-temperature resistance, high-precision coupling, smooth transmission, and long service life. It can be configured with a single (or multiple) gear pump.

3. Control System: High-precision dual-path temperature control facilitates future process expansion.

4. The melting cylinder, gear pump, reflux valve, and filter are designed with an optimized combination.

Simply put, the working principle of a gear pump hot melt adhesive machine is "using electric heating to turn solid glue into liquid → using a gear pump like a 'precision water pump' to pump the glue to the place where it needs to be glued → the glue quickly solidifies and sticks firmly when it cools." The "precise quantity control" of the gear pump is the key that distinguishes it from other hot melt adhesive machines (such as plunger pumps and diaphragm pumps). It can ensure stable bonding quality and no glue waste, and is particularly suitable for scenarios such as paper bags, packaging, and woodworking that require high glue application precision.

The above are Oushida gear pump hot melt adhesive dispensers. If your products require uniform and stable adhesive application, you can select the model that best suits your production line based on the different data of these gear pump models. All of these models are equipped with a PLC temperature control system and an LCD touch screen, allowing for intuitive and convenient operation with precise temperature control.

These models also feature a built-in glue dispensing control system with automatic speed and glue volume tracking, allowing for customized adjustments to the customer's production line, ensuring automated glue dispensing without the need for an external glue dispensing controller.
