Common Faults and Maintenance Solutions of Fully Automatic Packaging Machines

Automated packaging machines are a kind of indispensable special equipment in the enterprise production process. If there is an abnormal shutdown fault caused by untimely maintenance during the long-term operation of the machine, it will bring losses to the manufacturer. Therefore, the on-site operators and equipment maintenance personnel of the user should strictly follow the operating procedures of the fully automatic packaging machine instruction manual to use the equipment, and regularly and specifically conduct maintenance and overhaul of the mechanical and electrical parts of various packaging equipment. At the same time, the problem can also be excluded and the equipment repaired by referring to the fault and maintenance solution of the automatic packaging machine.

Introduction to Fully Automatic Packaging Machine Equipment

The automatic quantitative packaging machine can realize the automatic weighing and quantitative filling of multiple materials and meet the requirements of integrated packaging and sealing. In production enterprises, according to factors such as the bag type design requirements, the amount of packaging weight, and the size of the space for placement on the site, choose a fully automatic vertical packaging machine, a fully automatic bagging machine, and a pillow-type packaging machine to connect and link with upstream and downstream equipment to realize production packaging automation. Although there are many models and specifications of packaging machines, their packaging process flows are almost the same. Therefore, equipment operators need to comprehensively understand and master how to use the fully automatic packaging machine and achieve pre-emptive and post-maintenance for possible faults.

(1), The sealing at the transverse sealing or longitudinal sealing part is damaged

Check whether the set temperature is too high, or the packaging speed is too slow and the sealing time is too long, resulting in the film being scalded. If the packaging machine is used for the first time, the heat resistance of the packaging film material should also be considered. At this time, the temperature setting should be appropriately lowered and the sealing time reduced. Under the condition that the sealing is intact, the temperature should not be too high. If the sealing part is still not smooth and there are wrinkles after many attempts, then the material problem of the packaging film itself should be considered.

(2), The packaging bag length damages the printed pattern

The transverse sealing cutter is sealed and cut around the color mark. Ensure that the packaging film drive slips due to the color of the non-color mark block being too light. After excluding this situation, the photoelectric color mark recognition sensitivity should be adjusted. Start the color mark tracking in the equipment function menu and adjust it according to the debugging method of the vertical automatic packaging machine cursor guided by the technical engineer.

(3), Unable to seal or the seal is not firm

First, rule out whether the transverse sealing temperature setting is too low, and appropriately raise the sealing temperature setting. If the seal still leaks air, then abnormal situations such as damage to the solid-state relay, temperature control module, and thermocouple need to be considered. Gradually detect and confirm which link has a problem, and replace the damaged spare parts in time. If the set packaging speed is too fast, it will also lead to problems such as the packaging machine cutter not being cut off, the film pulling deviation, and material jamming. At this time, the packaging speed should be appropriately reduced.

Four, Summary of Fault Repair and Elimination Schemes for Packaging Machines.

The phenomenon of packaging machine failureThe fault diagnosis of packaging equipmentThe troubleshooting solution of packaging machine maintenance
No response when starting up and unable to start upCheck if the emergency stop switch is resetReset the emergency stop switch
Turn off the main power for 20 seconds and then start up again
Leakage switch trippingElectric leakage from heating elements or other electrical appliancesCheck each electrical appliance one by one
Unable to increase the sealing temperaturePower trip of the breakerCheck for and eliminate short circuits, then reset
Unable to increase the sealing temperatureThe heating element is burned outReplace the heating element
Unable to increase the sealing temperatureThe temperature controller is damagedReplace the temperature controller
The temperature controller display fluctuates repeatedlyThe thermocouple is loose or damagedFasten or replace the thermocouple
When stopped, the temperature is normal, but when started up, the temperature dropsThe voltage is too low, resulting in a decrease in the power of the heating elementReduce the packaging speed or add a voltage stabilizer
When stopped, the temperature is normal, but when started up, the temperature dropsThe power of the heating element is too smallReplace with a higher power heating element
Unstable particle weighingThe speed is set too highReduce the packaging speed or contact the particle packaging machine manufacturer
Leakage from the bag sealThe temperature is not high enoughIncrease the temperature appropriately
Leakage from the bag sealThe pressure is not sufficientCheck if the total pressure is 6.5 kg
Leakage from the bag sealThe sealing time is too shortIncrease the sealing time parameter appropriately
Leakage from the bag sealThe front and rear horizontal sealing rollers are not sealed evenlyCarefully adjust the parallelism of the horizontal sealing rollers
Leakage from the bag sealMaterial is caught in the sealAdjust the feeding time or inflation delay
Leakage from the bag sealLeakage from the seal of small powder packaging machinesUse an extended screw to fill the bag deep to avoid dust contamination of the seal
Unable to control the cutting point or cut halfwayThe edge of the packaging film is wrinkled or there is a problem with the optical path quality, causing a photoelectric misoperationReplace the packaging film
Unable to control the cutting point or cut halfwayThe sensitivity of the photoelectric eye is not adjusted properlyReadjust the sensitivity of the photoelectric eye
Unable to control the cutting point or cut halfwayThe bag length is not set long enough, resulting in long and short bagsIncrease the bag length setting
Abnormal film pullingThe pressure of the film transport cylinder is insufficient or too highCheck if the film transport pressure is 2.5 kg
Abnormal film pullingThe belt is slipping or damagedScrape the surface of the belt with a saw blade or replace the belt
Abnormal film pullingExcessive static electricity on the packaging filmReplace the packaging film

The above are some fault and maintenance solutions for fully automatic packaging machines. In case of abnormal situations, users can be well aware of the maintenance or contact the manufacturer of automatic packaging machinery in time to solve the problem. If it is found that the machine parts are damaged or aged, they should be replaced in time to avoid abnormal risks in the use of the packaging machine.
