Common problems and solutions of three-side bag sealing machine:
Q: the bag is wrinkled when the middle cots pass?
A: 1. The cooling effect of the back seal is not good;
2. The pressure of the middle cots is uneven;
3. Too much air pressure;
4. Too much dust on the middle cots;
5. The back seal temperature is too high;
6. The air pressure of the feeding floating roller is too high;
7. The installation of the membrane plate is inclined;
Two, ask: at the front cutter roller, the film goes in one direction?
Answer: 1. The pressure of cots is not uniform, and the forward film goes in the direction of high pressure;
2. The tilt of the photoelectric frame should be kept level with the front cots; (Photoelectric frame forward to lift the film to go out, photoelectric frame back to lift the film to go in)
3. The perforating knife is not installed well, which is easy to become warped;
4. The thickness of both sides of the film is not uniform;
5. The pressure of the transverse sealing knife is not uniform, which is big to go there;
6. The membrane plate is inclined upward;
7. The middle cots are not parallel;
Three, ask: small membrane plate is not on the membrane?
A: 1. The white roller installation can not exceed the template, the best narrow 8mm;
2. The pressure on the hammer is small;
3. The upper film hammer has an outward and inward inclined pressure;
4. The membrane plate is inclined upward;
5. The pressure of the cots should not be too large;
6. Excessive feeding tension is not easy to film;
7 membrane roll tension is not good;
Q: How long is the bag?
Answer: 1. The dust of photoelectric head is more;
2. Insufficient photoelectric sensitivity;
3. Tracking electricity is not obvious;
4. The sealing knife pressure is too high;
5. There is dirt on the glue stick;
6. The air pressure of the feeding floating roller is too high;
7. Excessive feeding tension;
8. The longitudinal sealing knife ironing cloth roll is too tight;
9. The cross sealing knife temperature is too high and the bag is wrinkled;
10. Small air pressure at the front and middle cots;
11. Feeding and pressing are out of sync;
12. The distance between photoelectric and cutter is too long;
13. The difference between waiting time and heat sealing time is too large;
14. Too high speed;
Five, ask: the front cutter oblique?
Answer: 1. Membrane deflection;
2. Guide comb is missing or not straight;
3. Slant knife;
The knife comes to the top.
5. The bag with punch hole should come out the end first;
6. The diagonal line of the bag is not the same length;
Question: the material at the cutting knife?
Answer: 1. The guide comb is far away from the cutter.
2. The cutting knife is adjusted too low;
3. Wrinkled or warped bag is not smooth;
4. Fast feeding;
5. Guide comb is not straight or missing;
6. Install the lower cutting knife on the upper side;
7. Bags with hand holes should not go out first with hand holes, but should go out first with tail holes;
Seven, ask: back seal has bubble?
Answer: 1. The bottom plate is dirty;
2. Uneven pressure of sealing knife or uneven pressure of four corners;
3. Base plate deviation from center;
4. bottom panel silicone rubber can not be too wide;
5. The sealing knife is not installed;
6. Small sealing pressure and high temperature;
7. Cinnamon rubber is not smooth or aging;
8. If there are bubbles in the process of operation, the bottom plate can be cushioned with ironing cloth or the sealing knife is less inclined or overlapped;
Eight, ask: back sealing heat sealing wrinkle?
Answer: 1. The tension is not good, the membrane is loose and tight;
2. Pressure imbalance between cooling knife and heat sealing knife;
3. Unbalanced pressure of heat sealing knife;
4. Wrinkles on ironed cloth;
5. The cots pull the template diagonally;
Nine: Q: a false seal?
Answer: 1. When passing the joint, the joint picture is not aligned, one side is loose and the other side is tight;
2. When crossing the joint, the double-layer film at the joint is thick, and the small shovel is driven and moved by the film;
3. Flanging or curling at the back small template and spatula;
4. Rear photoelectric run;
5. The tension is not good, both loose and tight;
6. The edge holder should not be too far from the sealing knife;
7 composite less than the edge, single-layer edge curl;
Q: transparent back sealing edge leakage?
Answer: 1. Slitting and slitting;
2. The outside is too large;
3. The rear tension is too large for the film;
4. The rear template is wide or the template is not coated, resulting in the front template is not coated;
5. Back sealing knife pressure on the outside;
Q: Does the bag often appear inside and outside?
Answer: 1. The rear photoelectric tracking is insensitive;
2. Poor tension of raw materials;
3. Uneven feeding;
4. The number of the upper film is uneven;
5. After the white roller is not packed tightly, swing around;
6. Wrong film penetration roll; (black axis, dead axis)
7. Excessive post-feeding tension;
8. Smooth membrane surface;
Q: fixed length photoelectric can not keep up with?
Answer: 1. The picture is not aligned when passing the joint or the printing surface of the joint is too long;
2. Bag stretching;
3. Polarity error;
4. The photoelectric head is not sensitive or the dust of the photoelectric head is too much;
5. The set bag length is inconsistent with the actual bag length;
6. The tracking point is not obvious or cannot be found;
7. Wrinkled bags;
13. Q: two folds at the inner fold?
Answer: 1. Three-dimensional plate installation and long template is not a line;
2. The upper and lower plates of the stereo board are not aligned;
3. Small template is too narrow than large membrane plate;
4. Large membrane plate and small template are not a line;
Q: Does the bag that requires air tightness leak?
A: 1. Low temperature, low pressure;
2. The ironing cloth of the middle pad is off track;
3. Uneven film thickness;
4. The sealing knife does not coincide;
5. Too high speed;
6. Silicone rubber is broken;
7 silicone rubber hardness should reach 75%;
Question: the correction time is too long?
A: 1. The film reel is not installed in the middle position of the reel or is not inflated
