Seven Common Faults Of Pillow Packing Machine

Welcome to Foshan Land Packaging Machinery Co., Ltd, which is a factory specializing In the production of packaging machinery and has 15 years of production experience.

Today I will introduce you to seven common faults of pillow packing machines.

The first kind: The host fails to start.

The possible causes of the fault are as follows:

1. No power supply;

2. The switch is not closed;

3. Failure of control loop;

4. The fuse is blown.

Solution:

1. Switch on the power supply

2. Close the switch

3. Check whether the input end of each control loop has an open circuit

4. Replace the fuse

The second kind: Failure of the longitudinal seal

The possible causes of the fault are as follows:

1. The sealing temperature is not appropriate;

2. The longitudinal sealing wheel has foreign bodies, and poor contact;

3. The pressure of the longitudinal sealing wheel is too small or too large;

4. Longitudinal sealing heater does not heat;

5. Improper setting of temperature controller causes abnormal heater;

6. The packaging film is of poor quality.

Solution:

1. Adjust the temperature according to the packing film material, thickness, and packing speed;

2. Clean the surface of the longitudinal sealing wheel;

3. adjust the screw, so that the longitudinal seal pressure is appropriate;

4. Check the corresponding heating circuit and replace the damaged parts;

5. Set the temperature of the thermostat;

6. Replace the packaging film.

The third kind: Bad sealing of the transverse seal

The possible causes of the fault are as follows:

1. the sealing temperature is not appropriate;

2. There are foreign bodies on the surface of the transverse sealer;

3. horizontal sealing cluster film or pull the film;

4. The transverse seal pressure is too large or too small;

5. The transverse sealing heater does not heat;

6. Improper setting of the temperature controller causes the abnormal heater.

Solution:

1. Adjust the temperature according to the packing film material, thickness, and packing speed;

2. Clean the seal with a steel wire brush along the teeth;

3. adjust the eccentricity adjustment wheel, so that the speed of the transverse sealing is consistent with the speed of the film, not cluster film nor pull the film;

4. adjust the bolt, so that the transverse seal pressure is appropriate.

The fourth kind: the packaging film molding is not good or the longitudinal seal is unstable

The possible causes of the fault are as follows:

1. The packaging film is too narrow;

2. The tension of the packaging film at the entrance of the bag maker is improperly adjusted;

3. The center of the packaging film is inconsistent with the center of the longitudinal sealing.

Solution:

1. Replace the appropriate packaging film;

2. Adjust the tension regulating roller of the packaging film so that the tension of each edge of the packaging film at the entrance of the bag maker is uniform;

3. Adjust the fine-tuning knob on the packaging film roller to make the center of the packaging film inconsistent with the longitudinal sealing center.

The fifth way: the unstable display of bag length

The possible causes of the fault are as follows:

1. Proximity switch is improperly adjusted;

2. The chain of the CVT is loose and good.

Solution:

1. Adjust the proximity switch so that the distance between the top surface and the top circle of the detection wheel is 1~2mm;

2. Adjust the transmission chain tension to fit according to the CVT instruction.

The sixth Kind: Abnormal tracking

The possible causes of the fault are as follows:

1. The set value of bag length is inconsistent with the actual length value;

2. Packaging film color label printing quality is too poor or not obvious;

3. Improper adjustment of photoelectric switch position or sensitivity;

4. The packaging film shakes;

5. Other circuits are faulty.

Solution:

1. Correctly measure and reset the bag length;

2. Replace the packaging film;

3. Repeatedly adjust the position or sensitivity of the photoelectric switch until the response is accurate;

4. Adjust the brake pressure knob to eliminate the shaking of the packaging film;

5. Check the tracking circuit and tracking motor, and replace the damaged parts.

The seventh kind: When the longitudinal seal, The product is cutting

The possible causes of the fault are as follows:

1. The fork position of the conveyor is not synchronized with the transverse seal;

2. The supply conveyor chain vibration is too big;

3. The guide rail surface of the material is lower than the bottom surface of the bag maker, resulting in poor feeding;

4. Too small bag maker causes poor feeding.

Solution:

1. Operate the hand wheel to synchronize the fork position with the transverse seal;

2. Clean the guide rail of the chain and adjust the handwheel to make the chain tension moderate;

3. Raise the material guide surface;

4. Replace the bag maker.
