Battery Powered Strapping Tool Maintenance

 

At Quick Pak Inc, with nearly 27 years in the industry, we've being selling and repairing every major manufacturer's battery strapping tools. This experience has provided us with deep insights into the strengths and weaknesses of various designs.

Battery strapping tools come in various designs, but they generally fall into two main categories:

Type A: Single Motor – One Motor Drives Tension and Welding.

This category includes three variations:

Full Single Motor: A single motor drives tension, welding, and the welding press.

Servo/DC Motor Assist (Single Shaft): The main motor drives tension and welding via a single shaft, while a servo motor presses the welding arm.

Servo/DC Motor Assist (Twin Shaft): Like the previous design, but with a twin shaft configuration.

Type B: Dual Motor – Separate Motors for Tension and Welding

This type has two variations:

Twin Motor with Servo Assist: One motor drives the tension, while another drives the welding, with servo assist for welding.

Twin Motor without Servo Assist: These tools typically do not have an automatic mode, meaning there’s no automatic drive for the weld mechanism.

Why Do These Designs Matter?

Much like high-end cars, increased complexity in design often leads to increased maintenance and cost. Let’s delve into how this applies to battery strapping tools.

Twin Motor Designs: Twin motor battery strapping tools are among the simplest.

The tension motor drives the feed wheel through a small series of gears, while the welding motor drives the welding almost directly.

While simple, this simplicity comes with a downside: vibration. When the welding motor is engaged, vibrations from the welding arm are transferred throughout the tool, leading to several issues:

-The welding motor can break or spin itself out.

-Small bolts holding the motor in place may come loose.

-Solder connections on the battery and motor terminals may break.

Single Motor, Single Shaft Designs:

In a single motor, single shaft design, power is sent through a single shaft.

The motor spins in one direction to drive the feed wheel and in the opposite direction to drive the welding.

This design typically includes a series of planetary gears, one-way bearings, and a belt drive for the welding arm. The belt drive has several advantages:

-Soldering rarely breaks from motor or battery contact, making the tool more durable.

-Motors tend to last longer compared to those in twin motor designs.

-Bolts rarely become loose over time, making the tool very stable.

While there are several advantages of these tools, there’s a trade-off - one-way bearings can seize, jam, or stop functioning properly, requiring the entire tool to be disassembled for replacement.
