How Do I Choose the Best Used Baler?

1. The potentiometer with belt length control is at the zero position

Maintenance method of semi-automatic baler

Right!

1. The potentiometer with belt length control is at the zero position

1. There is a foreign object in the upper and lower extensions.

There are foreign objects in the upper and lower extensions, or the countersunk screws that fix the belt guide are loose, and the packing belt is stuck. Remove the upper station to remove foreign objects.

2. Crossbar 635 bearing is broken.

Improper adjustment of the balance position of the crossbar may easily cause the crossbar to rupture. The instructions should be adjusted correctly.

3. Improper backlash clearance.

Because the retracting roller has the function of tightening the belt, when adjusting the gap between the retracting and retracting rollers, the retracting roller should be mainly used, and the clearance of the retracting roller should be 0.05 to 0.1mm more than the thickness of the belt.

4. Baler roller wear

5.The thickness of the packing belt is too thick. The best choice for the thickness of the semi-automatic packing machine: between 0.75-1.1!

6.Shanghai Ziyou provides first-class accessories to prevent the baler from unwinding! The rollers are anti-slip!

1. The middle knife bearing is broken.

Check the cause and replace the bearing

2. The middle knife is worn. .

There are cutting edges on both sides of the middle knife. One side can be worn and the other can be used or replaced with a new knife.

3. The middle knife tube pin is broken.

Use a small punch to punch the broken pin and insert a new tube pin.

4. The tightening force of the baler is adjusted too tightly.

There is an inner hexagonal set screw on the adjustment nut. After loosening, the adjustment nut is rotated counterclockwise. After the adjustment is completed, the hexagonal set screw is tightened.

5. There is oil on the slipper or tightening the transmission belt.

Remove the slipper to remove oil, wipe it dry, and then assemble it in order.

6. The drive belt is too loose.

Lower the transmission frame (earth ground) or the motor backwards to tighten the belt.

7. The thickness of the PP packaging tape is too thin or the gap between the ejection rollers is too large.

The clearance of the unwinding roller should be only 0.05-0.1mm more than the thickness of the belt. Adjust it according to this requirement.

8. The magnetic control (cutting tape sensor) is faulty, and the magnetic disc is detached or damaged.

9. The crossbar balance position is not adjusted properly.

1. The temperature adjustment knob is not adjusted properly.

Inside the electrical control box of the packer, above the circuit board, open the control box cover, and you can clearly see an adjustment knob. Turn the clockwise direction to increase the temperature, and vice versa. The temperature is too high or too low, and the bonding effect is not good, so do not adjust it too much at one time, generally it can be adjusted between 4-5.

2. The power supply voltage is abnormal.

This machine should use 220V voltage. In many factories, the voltage is often insufficient. If you use a long cable again, the voltage will drop, the soup temperature will be lowered, and the motor will even be burned when it is tightly bundled.

3. The pull spring of the electric heating monster fails.

The long tension spring on the electric monster is tired. In this way, the inability to send the hot head between the two upper and lower straps results in half or even less adhesion.

4. Improper adjustment of the position of the ironing head of the baler.

The hot head is too high or too low, or left or right, it can't heat the upper and lower two layers of packing belt when it collides with the packing belt or the cutter. It should be adjusted according to the situation.

5. The middle knife bearing is broken.

The middle knife bearing is broken, so it cannot be pushed up, and the packing strap is pressed to make it stick.

6. The temperature inside the machine is too high.

The smoke exhaust micro fan malfunctioned, making the temperature inside the baler too high.

7. The heat-resistant wire of the iron is faulty.

Check whether the heat-resistant wire is broken or burned. If the nut is loose, tighten it.

8. The tightening force of the baler is adjusted too much.

Properly adjust the tightening force.

1. LS1 micro switch is faulty.

The micro switch below the slide on the LS1 is faulty or the shrapnel is blocked by foreign objects and cannot touch the contacts

2. Failure of LS5 micro switch.

When the LS5 is reset to zero, the contact is not closed, that is, the tape is not sent, and the tape is not moved.

3. Large clutch clearance.

4. Poor relay contact

The relay is not in good contact. Check relays RL-1, 2, and 3.

1.LS1 failure

LS1 failed to release the contact, readjust the shrapnel clearance.

2.LS1 failure

Although the LS1 is not faulty, stolen items are stuck between contacts and shrapnel.

3.LS4 failure

The LS4 is delayed, and the micro switch contacts are not released.

4. Clutch clearance is too small, add shims.

5. LS3, LS5 are faulty.

replace.

6. TD failure.

replace.

1. Tightening force is too small

Increase the tightening force.

2. The position of LS3 and LS5 is improper.

Adjust the position of LS3 and LS5 switches

3. Magnetic control TD is not good

replace.

1. The crossbar balance position is not adjusted properly.

2. There is a large clearance between the pulleys.

3. Tighten the tape wheel and the friction plate loose.

4. The transmission belt is loose.

5. The electromagnetic clutch has insufficient suction.

6. The upper and lower extension shafts are loose.

7. The lower extension installation is tilted.

1.Magnetron TD is damaged or loose

Replace new parts or reinstall

2. The magnetic disk is installed incorrectly.

3. There is oil in the friction plate.

4. There is a large clearance between the retracting rollers.

5. The binding force is too large.

Common situation

Condition one:

Handle the tape. When the tape is stuck in the middle of the roller, or there is a foreign matter that can't be removed, the handling method is as follows:

a. Remove the washer of the hex nut.

b. Loosen the two M5 countersunk head screws on the middle connecting shaft. Since these two screws are fixed in the notched part of the connecting shaft, the screws must be turned up.

c. Remove the connecting shaft, pick up the upper turbine, and remove the jammed object.

d. Assemble and restore according to the above cba method.

e. Pay attention to the 0.3-0.5mm gap between the nut and the L-shaped curved plate.

Situation two:

The semi-automatic packer does not automatically eject the tape. In this case, first check whether the "exit length adjustment" is at "0", and then check whether the process of passing through the tape is correct. If it does not work, a foreign object may be stuck near the feed roller, which will also cause this. One situation. Situation three: Do not cut the tape after tightening, there are many situations that can cause this situation.

a, tight adjustment is too tight

b. There is oil on the slipper or the slippery belt, which is located near the elastic adjustment. The oil must be removed and wiped off.

c. The belt is too tight, lower the belt drive base downwards, or adjust the motor backwards.

d. Use thinner belts or the gap between the rewinding rollers is too large.

Situation four:

Poor adhesion

a. The temperature is too high or not enough. Sometimes special tapes have poor viscosity. The temperature must be accurate.

b. The use voltage is not enough. There are many factory voltages, which are often insufficient. If you use extension cables or cable wires, it will cause a voltage drop, which will lower the originally adjusted temperature and even burn out when the motor is tightly bundled. Therefore, try to avoid using cables If you must use an extension cable, you must connect a thicker wire instead of a long one.

c. The 635 bearing under the middle knife is broken. In this case, it is heated and cannot be bonded at all.

d. The long pull spring on the electric stranger hand (swing bar) is tired, so the stranger hand cannot be positioned, resulting in half or even less adhesion.

e. The electric steel sheet is too high or too low, or it is to the left or right, so when it encounters the upper and lower PP belts, or the left and right cutters, it cannot enter the heating, and it must be adjusted according to the situation.

f. The micro fan for exhaust smoke is malfunctioning, which makes the temperature too high.

Situation five:

Does not operate when inserting the tape.

The LS1 micro switch on the right side of the upper slide is faulty or the shrapnel is blocked by a foreign object and cannot touch the contacts.

Condition six:

continuously working.

a, LS5 is faulty.

b. Although the LS1 is not faulty, but there are stolen items between the contacts and the shrapnel, or the shrapnel itself is stuck, making it impossible to release the contacts after the insertion.

c. When the LS5 returns to zero, the contact is not closed, so that the power supply works continuously as soon as the power is turned on.

Situation 7:

Cut off before binding.

a, the machine is too loose, adjust it tightly.

b, LS3 and LS5 are improperly positioned.

c. The magnetic induction switch withdrawing belt is faulty.
