Failure and maintenance of vegetable packing machine

When the vegetable packing machine is used for a long time. It may appear to be some mechanical and electrical faults.

We put forward some corresponding solutions and maintenance schemes for vegetable packing machines.

The sealing of the vegetable packing machine is not firm

The most common fault of the sealing machine is that the seal is not firm. We provide you with solutions to common problems

• The sealing of the bag cannot be sealed.

· The vegetable packing machine’s heat sealing temperature cannot reach or exceed the material’s specified temperature.

If the composite bag is lined with OPP and the entire thickness of the bag is 80-90 M, The heat sealing temperature must be 170 180 °C. If the material is PE and the overall thickness is 85-100 m, the heat sealing temperature must be 170 180 °C. It’s best to keep the temperature between 180 and 200 degrees Celsius. The heat sealing temperature must rise with the bag’s thickness to ensure heat sealing quality and speed.

· The vegetable packaging machine’s heat sealing speed is too rapid, and the mouth cannot be properly sealed.

It is also connected to the sealing machine’s speed. The traction roller is sent to cold pressing during cooling treatment. If the speed is too rapid, the seal is not heated. Which clearly does not fulfill quality standards.

· The pressure of the cold-pressed rubber tire of the vegetable packing machine is too high or too low.

Only the pressure between them is moderate. It can be well heat-sealed. The pressure can be adjusted by a spring.

• The bag cannot be completely sealed

· The heat sealing temperature of the vegetable packing machine is not enough or too high.

It is easy to solve the problem by increasing or decreasing the heat sealing temperature.

· The surfaces of the two heat sealing blades beneath the vegetable packing machine’s knife sealing point are not very flat.

Thermocouples are commonly used to monitor temperature changes, and the heat sealing device has three screws. The blade is strengthened by the middle screw, which supports the wire. Pressure springs and washers are commonly used on the other two screws. This structure is primarily utilized to control the heat sealing knife’s pressure.

· The skew in the middle screw and an improper pressure spring on the heat sealing knife.

The remedy is to re-calibrate the position of the vegetable packing machine’s central screw to be horizontal. The pressure spring should be adjusted if the upper and lower heat sealing knives are imbalanced. The heat sealing knife will fall when the spring is withdrawn. The heat sealing knife will rise upward when the bottom blade’s spring is tightened.

• The fuse of the vegetable packing machine is blown

The sealing machine of the vegetable packaging machine will make a “squeak” sound at the beginning, which can not work normally.

Even the fuse on the fuse is abnormal. When solving this fault, first check whether the power supply is normal. Then cut off the power supply to check whether the power supply is damaged. Then check the fault of the circuit or motor to eliminate the problem of a motor short circuit Usually.

When the motor of the vegetable packing machine is short-circuited, if there is current in the fuse, the winding will be blown out, resulting in the fuse blowing.

Another possible cause of this failure is that the fuse size is too small. You can solve the problem by trying to replace it with a fuse that can carry more power.

• “squeak” sound of vegetable packing machine

The fault of the “squeak” sound during the operation of the vegetable packing machine usually occurs in the operation process of the sealing machine. The “squeak” sound often appears suddenly, and then it will be found that the sealing speed is uneven. It results in the poor quality of packaging bag sealing embossing line of vegetable packing machine, which affects the appearance quality of products.

· If it often occurs. This phenomenon is mostly caused by mechanical damage or serious wear and poor lubrication.

First, find the fault location through sound inspection to solve this problem. Disassemble the back of the protective plate of the vegetable packaging machine, find out which gearbox the “squeak” sound comes from, and then remove the parts one by one.

If it is found that the lubricating grease in the gearbox is missing and there is no major fault in the gear, the cause of the fault is lack of oil. Then, add lubricating grease to the gearbox, add lubricating oil to the same specification, and tighten the screws to recover. After startup, the “squeak” will generally disappear, and the seal will become normal.

· If the joint is loose, seriously worn, and unclean at high temperatures, there is dirt on the surface. It can not be well synchronized with the traction wheel during the working process of the vegetable packing machine, and sometimes a “squeak” is sent out.

Its solution is to first compress the spring by hand. Then put one end of the high-temperature area on the rubber wheel. On the other hand, leaning against another rubber wheelset, the governor ran at low speed. Then start it and install it automatically in the high-temperature area.

· The DC motor and motor make the “squeak” sound. It may be that the motor-bearing oil of the vegetable packing machine is insufficient.

In this case, the burr should be removed and lubricated. In general, the sound can be eliminated.

• The sealing temperature of the vegetable packing machine is out of control

The sealing temperature of the vegetable packaging machine is out of control, which means that the thermometer shows failure and cannot control the temperature. It results in unsteady heat sealing temperature and poor sealing.

The main reason for this failure is that the thermometer broke. In addition, the thermocouple may also be damaged so that the induced temperature cannot be transmitted to the thermometer normally.

The solution is to repair or replace the damaged devices and replace them with devices of the same model and specification. The heat sealing pressure is unequal. The pressure may be constant as long as the heat sealing knife’s pressure spring is adjusted. At the same time, the heat sealing knife’s pressure contact surface on the vegetable packing machine should be kept clean and clear of dirt.

Another problem is the composite material’s performance, which includes poor heat sealing quality and a shift in heat sealing coefficient, resulting in temperature inconsistency.

• The speed of the vegetable packing machine is inconsistent

The phenomenon of the inconsistent speed of vegetable packing machines is also common. You can try tightening the screws to tighten all the connections of the vegetable packing machine. Furthermore, the primary motor is dependent on the carbon brush’s contact and functioning. The sealing machine will also stop.

If the carbon brush is severely worn and the ring is not in full contact, the friction performance is poor. Replace the carbon brush with a new one of the same type.

• sealing failure of vegetable packing machine

The look and the uneven trail of the vegetable packing machine’s sealing foam. Although it does not cause the packing to leak, it detracts from the attractiveness of the package and degrades the product’s appearance.

The apparatus has been in use for a long time, and dirt such as high-temperature dust and plastic dust is attached. The high-temperature area of the vegetable packaging machine is not clean, smooth, and uneven, resulting in uneven heat insulation.

it is best to replace the cold pressing rubber wheel Because it can ensure the beautiful shape of the bag,
