The linear weigher packing machine differs for the conventional weigher in the following ways:

Different Test Data Reliability

The sensor weighs employing dynamic situations because the conventional weigher weighs with material addition.

For a linear weigher, where you impact the weighing object, the sensor detects unstable weight resulting in inaccuracies.

Weighing Speed

In a conventional weigher, you undertake coarse measurement and fine measurement the latter taking the longest time and influencing speed.

The liner weigher machine contrarily achieves speeds up to 6 times faster employing rapid optimization and combination computation.

Drop Error

You find this error common in linear weighers causing substantial inaccuracy.

Occurs when the electromagnetic vibrating feeder stops and the weight value in the hopper reaches the predetermined value.

Weighing Range Difference

The weighing range of a linear weigher is greater than that of a conventional weigher with the same accuracy.

Under typical conditions, you can achieve up to four times the weighing range accuracy of a conventional weigher with a linear weigher.

Different Working Approach

While feeding, the quantitative automatic packaging scale weighs and continues feeding until you obtain desired weight data.

A small discrepancy between the target weight and obtained weight requires adjustment through fine measurement.

A linear weigher employs the permutation and combination principle in the automatic optimization and calculation of weighing unit’s load.

You find the following interventions handy in increasing the efficiency of a linear weigher packing machine:

• Automating the machine such that it automatically shuts down in case of inadequate material or absence.

This protects the weigher’s operation stability and prevents damage from operating when empty.

• Employ the gain function to modify the amplitude strength and make the material conveying seamless.
• Present the vibration machine’s setup function such that you can independently set up the amplitude instead of applying general setting.
• Set a weighing and counting function such that you can utilize numbers while weighing items during computation.

This provides customers with additional options and is superior to counting in grams.

• To control material addition, apply the primary vibration setting.
• Using a sequential discharge function helps you avoid blockage by discharging product into the weighing hopper in order.

The linear weigher packing machine combines modern technology to enhance performance and efficiency.

You ensure consistent output by ensuring proper use as well as daily maintenance.

Some of the precautions when using a linear weight packing machine includes:

• Before leaving their positions, shift workers must clean up the machine by removing dust, discharging water, and powering down.
• Make weekly inspections of the machine’s transmission and moving components, tightening loose parts and oiling movable parts.
• Personnel trained in debugging should master the machine’s performance, operating modes, working state, working methods, and common error diagnosis.
• The operators of a linear weigher packing machine need adequate training allowing them to master the setup and packing methods.
