metal roof tile making machine is used in industrial and civil buildings, such as factories, warehouses, stadiums, exhibition halls, theaters and other room surfaces and walls.   
Sometimes there are some defects while production process. Painting defect is one common defect.

Cause Analysis:

First, the gap between the shaft and the shaft is too small;

Second, pressure tile surface roughness;

Third, the color plate surface improperly painted;

Fourth, the pressure wheel has a zinc layer.

Method of exclusion:

2. Grind the pressure wheel with oilstone and wait until the oil is smooth;

Big head and small tail phenomenon

Cause Analysis:

First, the center is not on the same line;

Second, the gap size is not the same.

Method of exclusion:

First, find the center again, the gap;

Second, if the front is large and small, you can press the first row of shafts down to the second row. If you are small, you can press the second row to the first row.

3.Runaway phenomenon

Cause Analysis:

One, the center roll is not correct;

Second, the inlet baffle and the profile axis are not perpendicular.

Method of exclusion:

1. Correct the center roll and correct the center roll.

2.adjust the inlet baffle to see the product's skew direction, and then correct it.

4.Hard analysis

Cause Analysis:

First, the feed rack is too high;

Second, the first and second rows of shaft gap is too small;

Third, excellent material.

Method of exclusion

First, reduce the feed rack;

Second, enlarge the gap between the first and second rows of shafts;

Third, with the bending machine on the color plate measurement appears the same problem, please replace the color plate.
