Linear weigher common troubleshooting

The linear weigher is mainly used for grain, seeds, nuts, food, seasonings, and other granular materials with good mobility, at present, China's linear weigher industry is still on the road to continuously improve technology and improve the innovation ability of packaging and weighing machinery products, but also has a strong scientific and technological competitiveness. Good products used improperly will also have problems, the following is an introduction to the linear weigher common troubleshooting.

Here is the content list:

l A mold sealing bad

l The photoelectricity problem

l The temperature does not rise

l The temperature control can not

l The main motor does not turn

A mold sealing bad

This problem is also relatively common, first, we have to find a simple place to see whether the linear weigher temperature to reach the packaging film sealing temperature, if reached the following check whether the mold pressure to reach, if there is no problem that is the linear weigher mold teeth did not bite or left and right pressure is different.

Solution: The first problem is solved by adding temperature, the second problem is solved by adding pressure, and the third problem is solved by re-pairing the molds of the linear weigher to one side.

The photoelectricity problem

This problem is also more often, linear weigher photoelectricity out of the problem is generally manifested as the go-bag length will change the length is not the same.

Solution: film in walking photoelectric has not swept to the film above the mark, check the linear weigher photoelectric eye has no dust, check whether the photoelectric eye sensitivity is adjusted right, check whether the film by the impact of photoelectric eye recognition of miscellaneous colors, if there is a need to find a point without miscellaneous colors, if you cannot find, your packaging film can be thrown in the rubbish.

The temperature does not rise

This problem is relatively good judgment, but for newcomers or more difficult, first need to check the linear weigher fuse is not bad, and then check the relay is not bad, use the table to test the next know, notable on the test pen, if not bad next is to look at the linear weigher heating rod wiring is not loose, if not then we need to take down the heating rod line to test the resistance, if the resistance infinitely large that this heating rod can be retired. There is also the thermocouple damage, this problem is very good to determine, either the linear weigher temperature control table on the leftmost display a 1 word, or the temperature has been jumping again amplitude is very large. Directly replacing the thermocouple can be solved.

The temperature control can not

There are two reasons for this problem, one is the linear weigher temperature control table is bad, one is the relay is bad, first test the relay, because this bad slightly more.

The main motor does not turn

First look at the fuse, if not bad to see if the relay of the main motor is damaged, if not bad is the linear weigher motherboard problems.
