1. Eccentricity: the size of the foil nailed by the nailing machine is unstable, the scissors are not good (the cut foil should be straight), the force of the foil pressing rod is large/small, the winding is early/late, the electromagnet is released early/late, the electromagnet stroke is large, whether the foil retreats after the scissors cut the foil, the sensitivity of the optical fiber is strong/weak, and the cardboard is pressed early/late.

2. Broken foil in the core: the nail is off-center, the nail is inclined, the force of the foil pressing rod is too large, the electromagnet is released too late, the foil blocking steel wire is too high/too hard/inelastic, the foil feeding table/foil pressing rod is worn, the fixed blades of the scissors on both sides are too high/too low, the guide pin is scratched, the winding speed/parameters are not coordinated with the action, the stroke of the foil pressing rod is too short, the mechanical action is incorrect, and the burrs on both sides of the aluminum tongue of the guide pin are serious.

3.

Nailing deviation: the center line of the aluminum tongue of the guide pin does not coincide with the center line of the aluminum handle, and the slide seat of the needle feeding claw is not positioned right and left, which scratches the guide pin during needle feeding, and the distance between the pusher and the positioning claw of the guide pin is too large.

Group maintenance skills

First, assemble the machine:

1. Adjustment of the number of holes: firstly, determine the lower limit position of the bearing distance of the sliding shaft of the leather head detection needle when it moves 3-4mm for the first time; If it is not enough, it is necessary to adjust the upper limit position of the bearing after adjusting the connecting rod; If the leather head of the detection needle is too high or too low, adjust the needle to hold the leather head with high pressure so that it is not higher than the bell mouth of the aluminum shell; Then, adjust the photoelectric until it just lights up, and the charging electromagnet will light up when there is no product.

2. Do not seal the photoelectric detector: When the sealing needle is pressed to the lowest position, the 67 1 photoelectric detector is only turned on or off (some photoelectric devices are normally open and some photoelectric devices are normally closed).

3. The seal was smashed:

① The aluminum shell and the assembly template are not in the same center (adjust the positioning screw of the assembly template);

(2), assembly template and beam template are not in the same center;

③ The sealing position is wrong;

(4), refueling cotton ball wear.

4. Improper hole selection: the two needles of the hole selection needle are high or low. If the hole-selecting needle is normal, take it down and feed it horizontally, put a leather head on the hole-selecting needle to align with the waiting rod, rotate the hole-selecting needle, adjust the position of the waiting rod, and then level and feed it to align with the waiting rod.

5、

Clamping flat: there are foreign objects in the beam mold, the vibrating plate is not aligned with the flat feeding, the vibration amplitude is too large, the vibrating steel plate and the ejector pin of the beam mold are not high enough, and the return steel wire is not adjusted properly.

6. The leather head is drooping, and the sealing is not strict: the component is jacked up quickly, the upright post is assembled, the detection needle is too high or too low, the sealing needle is not in the right position and the size does not meet the technical requirements, and the refueling machine is not in place.

7. Twisting feet: incorrect or bent punching needle position, large core spacing, needle sealing or cotton ball touching the guide needle, incorrect assembly, etc.

8. Blanking, foot bending and single hole stringing: whether the flat feeding, the moving clamp and the fixed clamp are on the same straight line, whether the turnover clamp, the guide die and the leather head clamp are on the same center point, whether the hole selection position is good, whether the legs are normal, whether the actions between the clamps are coordinated, whether the guide die is not straight or has foreign matter, whether the turnover clamp is clamped incorrectly or damaged, whether each clamp has foreign matter or jammed products, and whether the spring is broken.

Second, the conjoined machine:

2. Poor sealing: aluminium scrap and aluminum wire: 686 bearing is stuck, needle sealing is not smooth or locked too tightly, needle sealing angle is not right, chamfering is too much or too little, etc.

3. Loose sealing: too few chamfers, too low leather head, too long size and insufficient needle sealing angle.

4. Casing wrinkling: improper adjustment of centralizer fixture, deviation and bending of upper die pin, improper blades, dislocation of casing seat, and too large or too small casing bending diameter.

5. Poor thermal shrinkage: insufficient temperature, too large or too small blowing, incorrect blowing pipe, too long or too short heating time, etc.

6. Bottom depression: double aluminum shell does not stop, photoelectric failure, lower aluminum shell slider is adjusted too low, and there are foreign objects in the beam mold.

7. No belt ring and no seal: 628 bearing explodes, belt breaks, waist shaft bends or position is improperly adjusted, and the main shaft is stuck.

8. The leather head is smashed: the positioning of the leather head clamp and the low ejection rod at the top of the leather head lead to double leather heads, and the ejection will be rotten.

9. Uneven exposure and edge: the rubber tube is damaged, the U-shaped clamp is not clamped, the blade is not installed, the blowing seat is not straight, and the blowing amount is uneven.

Three, rubber machine:

1, product bending foot: the split foot is too large or too small, and each detection seat is positioned, and the flat feeding stop is positioned.

2. Poor thermal shrinkage: the position of the blowing pipe is incorrect, the blowing pipe is deformed, the height adjustment is not good, the air volume is insufficient or too large, and the temperature does not meet the casing material.

3. Clamping flat: the bare product of the movable clamp is not clamped in the middle, the baffle is bent, and the connecting rod of the righting clamp is adjusted too long, resulting in too tight stress.

4. Foot twisting: the moving clamp and the flat feed are not in a straight line, the whole leg group moves, the flat feed stop moves, the upper moving clamp and the lower clamping are not in the same center point, and each leg is broken.

5. Casing burn: improper adjustment of temperature and air volume, blowing pipe touching the product, poor material.

6. The long surface of the bottom is short or the short surface of the bottom is long: the casing flattening seat, the hose feeding screw is too high or too low, the blowpipe is too high or too low, and the righting clamp is not correct.
