Adjust 2. blowing pressure and blowing time;

3. flat joint surface or pad aluminum foil on mounting surface;

4. check waterways, remove scale and adjust water flow;

5. adjust the distance between heating plate and grinding tool (generally 1 mm), usually do not need to adjust the height of heating plate position;

6. replacement of qualified PVC;

7. dredge the exhaust hole;

8. adjust the abrasive tool to make it right;

9. reduce running speed.

Deviation in PVC step by step

1. forming abrasive is not parallel to large plate;

2.PVC sheet preheating temperature is too high;

3. heating plate coating damage;

4. forming step roller group working time is wrong;

5. limit block position is wrong.

1. adjustment molding abrasive and large plate is not parallel;

2. reset the heating temperature;

3. replacement of heating plate or re-spraying;

4. adjust servo motor step time;

5. adjust the block position so that the PVC center to the large plate 220 mm.

Bad sealing

After 1. sealing, aluminum foil is wrinkled;

After 2. sealing, aluminum foil is pressed through or pinhole;

3. sealing roller and active roller axis is not parallel;

4.PTP glue quality is not good live failure;

5. sealing roller heating pipe damage;

1. adjustment PTP each guide roll parallel to each other, perpendicular to the large plate;

2. reduce the sealing pressure, remove the burr on the sealing roller;

3. adjust the sealing roller support so that the contact between the two rollers is a straight line;

4. replacement of qualified PTP;

5. replacement of heating pipe;

Bad sealing

6. sealing roller temperature or pressure is too high

7.PVC and PTP sealing area is too large.

6. adjusting sealing temperature or pressure;

7. active roller surface to process grooves or reduce sealing area.

Bubble cover and active roll hole nest do not match, bubble

1. step distance size is wrong;

2.PVC deviation when stepping;

3. after forming bubble cover into a straight line;

4. transmission sprocket tooth number is incorrect.

1. adjust the pulse value of servo motor;

2. see PVC deviation adjustment method;

3. adjustment molding abrasive and large plate parallel;

4. replace the sprocket with the correct number of teeth.

The typing indentation is not correct

1. typing adjustment roll adjustment is not in place;

2. around the swimming roll package bubble cover belt can not lift the swimming roll, so that the package free string;

3. header clip reverse.

1. adjust the upper and lower position of the typing adjusting roller;

2. re-wear the package, so that the roll slightly lift tension;

3. change direction reload.

The solenoid valves are unstable when the machine is running

1. rotary encoder connection loose;

2. detection photoelectric switch installation loosening.

1. fastening rotary encoder connection;

2. fastening the connection between the photoelectric switch and the machine.

Automatic correction is not reliable

1. detection has reached the limit position;

2. the executing agency is at the limit;

3. package edge detection switch position is incorrect.

1. reposition the limit detection switch;

2. restructuring the implementing agencies;

3. reset the position of the detection switch.

III. Maintenance

1. machines should be wiped, cleaned and kept clean.

2. Often check the operation of the machine, find problems in time to deal with.

3. Lubricate the equipment on time according to lubrication requirements

4. All cooling parts of the are not broken water. Water supply before starting, then heat the heating parts; when the production is terminated, stop the water supply after the heating parts reach normal temperature.

5. the surface of the hot sealing roller to keep clean, remove the attachment with a fine copper brush in the heating state. At the same time, the operator should pay attention to the range of operation and the distance between the hand, arm and body and the heating roller to avoid scalding.

After the 6. work is finished, the power supply is cut off first, the heating parts are cooled to normal temperature, and then the water source and gas source are closed.

7. wear in use or storage, do not bump scratches, do not contact with corrosion.

8. the equipment is not used for a long time, the water in the waterway and air should be blown out with compressed air, all parts of the oil, and plastic cover.

IV. Points for attention

1. the machine work, do not put the hand into the molding, sealing, typing, punching and other moving parts, wear packaging film should pay attention to heating parts, so as to avoid scalding.

2. the operation of the machine, do not adjust the transmission parts and moving parts, do not use the hand to clean the blanking place of waste, plate.

3. tools, parts and other items shall not be placed on the PVC of the platform and on the front-end actuators or shields of the machine to avoid forgetting or vibration falling into the mechanism,

4. do not arbitrarily adjust the various mechanisms and gas, water control valve, to avoid failure.

5. the ground wire of the machine to be reliable, replace the heating element to carry out insulation test.
