Set of labeling machine common faults and solutions (1)

Shrink film is easy to accumulate in the center column or card material

Cause of:

1. When the film material is manufactured, the control of folding diameter is too large or too small, especially in the standard size of the lower thread (small), it is more likely to cause the center column to accumulate material.
2. The clamping point of the center column adopts a single point of clamping and is also more likely to cause unstable clamping, so that the center column cannot become a line and cause material accumulation.
3, the intensity of adjustment of the up and down drive tires is inconsistent.
4. When the edge of the cutter blade returns to the origin at every turn, it may stop in the groove of the center column, causing the label of the film material to hit the blade and form a material accumulation.
5. The central column groove may have a phenomenon of being cut by the cutter, which may cause the subscript to be not smooth, and thus may cause a stuck material.
6. When the label after being cut off is waiting to be brushed, the next round of the brush will not smoothly insert the cut off label into the bottle to cause a domino effect, and the reaction will cause the central column to accumulate.

solution:

1. The label supplier is required to control the folding diameter within ±0.5%. 0
2. Multi-point clamping machines and equipment are better than single-point clamping, but the labeling machines of different brands all have different designs, so users should choose carefully when purchasing.
3. Correctly adjust the force of the upper and lower drive rubber wheels. 4. Check whether the origin of the cutter is correct and check the matching of the entire process control. Be sure to drive the next material within the effective time after the cutter leaves the center column. In addition, the cutter should stay inside the cutter plate every revolution, and must not be too close to the center column groove so as to ensure no accumulation of material.
5. If there is a cut in the center column groove, the surface treatment can be smooth.
6. Make sure that the clamping contact between the brush wheel and the center column does not deviate, and that the brush is not worn out and the force under the brush cannot be equalized. Brush the label and drop it into the bottle, otherwise the label will This can cause a chain reaction to accumulate in the center column.
Shrink film cut position is uneven, with flash

Cause of:

Because the market's sleeve labeling machines mostly belong to the cutting point overlap design method of multiple knives, the burrs are difficult to control.

1, the label is too large, the deviation of the center column diameter and film material deflection is too large.
2. The correction point of the cutterhead is not on a line.
3. Inside the cutter head group, the gap between the eccentric shaft groove and the bottom of the tool seat is too large, resulting in uneven blades.
4, blade strength is not enough.

Solution:

1. Do a good job of controlling the size of the label, and check the diameter of the label and the diameter of the center column.
2. After the blade is replaced, the flat point must be confirmed. In addition, the tightness control of the lock blade should also be appropriate.
3. Replace the relevant parts inside the cutter head.
4, replace the new blade.
