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.
