1.The glass pump no bottle no filling function of ampoule filling machine can not work normally？
Possible cause:
1.No bottle no filling detection signal of detected optical fiber is normal or not. Under normal circumstances, only one signal can be detected for each bottle passing through.
2. Whether the electromagnet is damaged.
3. Check whether there is any problem with PLC input and output signals.
4. Check whether the electromagnet and signal line is loose or broken.
5. Check if the encoder reset signal is in the middle of the first bottle and the last bottle of the previous round.
6. Detect whether the electromagnet action signal starts to act when the filling pump falls to the lowest position.
7. When entering the bottle, the bottle itself shakes a lot, resulting in a misjudgment of the detection signal.
Solutions:
1. First, check whether the switching operation of the full-filling and full-no-filling functions are normal, check the gap between all the electromagnet shafts and the filling pendulum rod, and check that there is no blocking phenomenon when the electromagnet shaft extends in and out.
2. Replace the electromagnet with a new one.
3. Monitor whether the ampoule filling line’s PLC signal is running normally, and replace the PLC if there is a problem.
4. Check the signal line and power line for no bottle no filling function.
5. Adjust the fiber installation position and the origin reset position.
6. Detect the action time of the electromagnet to ensure that the electromagnet rod can smoothly extend in and out.
7. Minimize the shaking of bottles, ensure the smooth transition of bottles, and only detect one signal whenever a bottle passes.
2. When the electromagnet controls the ampoule filling mode and selects the no-filling mode, there are still individual pumps filling.
1. There is a problem with the electromagnet coil itself.
2. There is a problem with the electromagnet circuit.
3. There is a problem with the return spring of the electromagnet and cannot be reset in time.
4. There is a problem in the gap between the electromagnet shaft and the side of the filling connecting plate.
5. There is a problem in the gap between the electromagnet shaft and the installation face of the filling connecting plate.
6. There is a deviation in the electrification time of electromagnet action.
Solutions:
1. Replace the electromagnet with a new one.
2. Check electromagnet wiring problems. Usually, the problem is at the electromagnet power cord swings back and forth at the bend.
3. Replace the spring with a new one.
4. Adjust the left and right positions of the electromagnet installation, there is a gap between the electromagnet shaft and the side after shrinking.
5. Adjust the position of the electromagnet before and after installation. There is a gap between the electromagnet shaft and the end face after the electromagnet shaft is extended.
6. Adjust the electric signal of the electromagnet. When the filling pump just falls to the lowest point, the electric signal of the electromagnet will light up.
3. After the plunger type ceramic pump, plunger type metal pump, and glass pump finish the ampoule filling action, there is a problem that the gas return in the silicone tube.
Possible causes:
1. The connection between the silicone tube and the dispenser, needle, and filling pump is not well sealed, and there is air leakage.
2. The ampoule filling needle itself has an air leakage sand hole.
3. Plunger-type ceramic pump, plunger-type metal pump, glass pump, white core, blue core have poor sealing, etc.
4. The dwell time after filling is too long.
Solutions:
1. Check the leak point and replace the matching silicone tube to ensure tightness.
2. Replace the needle with a new one.
3. Replace with a new filling pump, blue core, and white core.
4. Minimize downtime of ampoule filling machine.
4.The problem that the opening angle of the wire drawing pliers of ampoule filling and sealing machine is too small
Possible causes:
1. The wire rope of the wire drawing pliers is not tightened, and there is no tension when tensioning so that the wire drawing pliers cannot be opened to an ideal angle.
2. There is a problem with the installation position angle of the small shaft drive gear of the front and rear wire drawing pliers, which is caused by mutual tension.
3. The cam of the wire drawing clip is seriously worn.
4. The angle adjustment of the wire drawing pliers itself.
Solutions:
1. Tensioning the wire rope a bit and readjusting the position of the wire drawing pliers.
2. Disassemble the wire drawing box and reposition the gear of the wire drawing pliers shaft.
3. Replace the drawing pliers cam, and adjust the drawing wire rope.
4. Loosen the fixing seat of the wire drawing pliers, and adjust the gap between the front and rear wire drawing pliers and the bottleneck according to the second act of the wire drawing cam.
5.The tension and contraction force of the wire drawing pliers are too small.
Possible causes:
1. The wire drawing pliers’tension spring of the ampoule sealing machine is fatigued and lacks elasticity.
2. The tension level of the wire drawing pliers’ wire rope is inappropriate and too loose.
3. The compression spring in the wire drawing box is compressed and bent when compressed, and the elastic force of the spring will lose a lot.
Solutions:
1. Replace the spring.
2. The wire rope can be properly tensioned.
3. Change the angle of the clip gear to ensure that the spring can naturally straighten when the clip is closed so that the elastic force of the contraction will increase. If the spring has been deformed and lost its elasticity, a wrap can be temporarily added to the outside of the spring to prevent the spring from bending.
6.The problem that the wire drawing rope is easy to break
Possible causes:
1. Check whether the wire rope is original or purchased and replaced by yourself.
2. The wire rope itself is relatively tight with the cam, and it runs under a large force for a long time.
3. Lubricate with oil when installing the wire rope, or maintain it without oil for a long time.
4. The threading hole of the wire rope platen is not perpendicular to the connecting seat of the swing arm, which causes the unilateral wear of the wire rope to be fast.
Solutions:
1. Replace the wire rope with the standard outer diameter.
2. Loosen the wire rope, let the clip and swing head in a free state, then tighten the wire rope splint, and adjust the tightness of the wire rope.
3. There is no lubricating oil in the wire rope sleeve, which causes the resistance of the wire rope in the rope sleeve to increase, and accelerates the breaking of the wire rope over time. The solution is to add oil before installation and regularly add lubricating oil.
4. Adjust the position of the wire rope swing rod and cam according to the position of the table guide hole, and try to ensure that the wire rope runs vertically up and down.
