Solution to common faults of pillow packing machine

Solutions to common faults of pillow packing machine
1. Partial failure of membrane guide groove:
The film cannot bite into or fall off the hot roll of the top pillow packer, or the end is not aligned.
Cause 1: the film center, guide groove, longitudinal sealing roller and transverse sealing roller are not in a straight line.
Cause 2: The guide vane slot is too inclined.
Cause 3: Abnormal rotation speed of eccentric sprocket of transverse sealing heat roller.
Adjustment method 1: roll up the vertical sealing pillow packing machine, turn the adjusting knob to the right to increase the pressure, and the film thickness will be lengthened. It should be noted that if the tension is too large, the seal cannot be sealed.
Adjustment method 2: Reduce the pressure of the longitudinal heat sealing roller. If the pressure is too large, it cannot be sandwiched into the film and may be extruded.
Adjustment method 3: The clamping amount of the longitudinal sealing roller is more than usual, generally 10 mm to 7 mm.
Adjustment method 4: If the two ends are still uneven after the above adjustment of the pillow packing machine, bend the film inward beyond the guide groove on the side.
Adjustment method 5: there is an error in the center line of the film guide groove, and the manufacturing defect should be replaced.
2. Cutter part failure.
(1) Cannot cut film:
Cause 1: The clearance between the moving tool and the fixed tool is not adjusted properly.
Adjustment method: There are two short fastening screws on the outer side of the fixed knife, and two long compression screws on the outer side of the fixed knife. When the blade of the moving knife is close to the fixed knife, the film is cut through the grinding of two knives. The clearance Z between the blades of two pillow packing machines should be 1/100 mm. At the same time, clamp the cutting film by hand during adjustment, and the cutter clutch should be disengaged during adjustment.
Reason 2: If the cutting blade is damaged, use an oil stone grinder for minor repairs, and use a grinder for major repairs.
Cause 3: the cutter is not installed properly, the cutter clutch is not in good clutch, and the positioning key is disengaged.
Solution: Carefully check all parts and retighten them.
3. Fault of transverse sealing heat roller: poor sealing.
Cause: poor thermal regulation, insufficient or uneven push spring pressure.
Adjustment method: appropriate pressure and temperature shall be selected according to the thickness and type of packaging materials used. If the sealing temperature is too high, the sealing will turn white, and the packaging film at the sealing place is easy to peel off. The pressure of each heat sealing roller is adjusted by the push spring, and the temperature of the roller is controlled by the temperature controller, thus controlling the temperature of the heating rod. There are pressure adjustment buttons on the left and right side of the transverse sealing roller, and each adjustment button is composed of push pillow packer button and pull button. The push-pull button is adopted, and there are two adjustment buttons on the transverse sealing heat roller to prevent uneven lateral force adjustment.
4. Turntable part failure:
(1) The packaging material is mixed into the heat sealing part.
Cause 1: The bagging time is not consistent with the heat sealing time
Solution: The double gear is connected with the rotary table gear. Push up the double gear to change the mesh, so that the material will not fall when sealing. Don't change it easily when appropriate.
The second reason is that the packaging speed is too fast and the blanking time is long, so the packaging speed should be reduced appropriately.
(2) The unloading time has been adjusted, and the exception occurs again.
Cause: The turntable is not fixed properly, the keys and fixing screws are loose, or the fixing position is incorrect, and the shutter in the turntable is not opened and closed correctly.
Maintenance and adjustment: fix the turntable in the correct position of the pillow packing machine, and re-fix the keys and screws. After adjusting the opening and closing mechanism of the shutter to the correct position, fix the shutter. In addition, when loading powder with very small particles or mixture with great difference in specific gravity, the bagging time is long, resulting in the powder particles biting into the sealed part. It should be suitable for the characteristics of the packaging material.
5. Electrical part failure
(1) The current of heat sealing roller is too high or the fuse is blown
Cause: The electric heater is short-circuited or the heat seal circuit is short-circuited.
(2) The heat sealing roller is not hot
Cause: one heating wire is blown, the second fuse is blown, and the third temperature control is faulty. At this time, set different temperatures, and the traffic lights do not jump
