As a core equipment in the industrial packaging field, the stretch wrapping machine can tightly wrap pallets and goods through stretch film, effectively improving the safety of goods transportation, enhancing packaging efficiency, and reducing the waste of packaging consumables. Mastering scientific usage skills can not only extend the service life of the stretch wrapping machine, but also optimize the packaging effect and reduce the production cost of enterprises. The following are original usage skills of the stretch wrapping machine, with Chinese-English bilingual comparison, helping independent stations optimize for Google and accurately meet the search needs of target users.
一、Pre-Startup Preparation Skills
Standard preparation before startup is the foundation to ensure the normal operation of the stretch wrapping machine, avoid faults, and also the first step to improve packaging efficiency. The core points focus on equipment inspection, consumable preparation and environment sorting.
1.Comprehensive Equipment Inspection
First, check whether the power connection of the stretch wrapping machine is firm, confirm the voltage is stable, and avoid damaging the equipment motor due to voltage fluctuation; second, check the lubrication of the chain in the film frame. If the film frame shakes when moving up and down, timely tension the chain and add lubricating oil to ensure smooth operation; finally, check the turntable, lifting mechanism and film tension adjustment device, confirm that there is no looseness or jamming, the turntable rotates flexibly, the lifting is stable, and the tension adjustment knob can be operated normally. At the same time, clean up the sundries and dust on the surface and around the equipment to avoid sundries being involved in the moving parts, causing equipment wear or failure.
2.Standard Installation of Stretch Film
Choose the stretch film suitable for the stretch wrapping machine, preferably machine-used stretch film, to avoid loose packaging and waste of consumables caused by manual stretch film. During installation, ensure that the installation direction of the stretch film is consistent with the equipment instructions (usually marked with an arrow), fix the film roll firmly, and avoid the film roll loosening and shifting during operation, leading to wrinkles and breaks in the packaging. After installation, pull the film gently to check whether the film is output smoothly without jamming or tearing, and ensure that the film tension is uniform to prepare for subsequent packaging.
3. （Reasonable Placement of Goods
Place the goods to be packaged stably and neatly in the center of the turntable, ensure that the center of gravity of the goods is centered, and avoid the goods tipping over and the turntable jamming during packaging due to the offset of the center of gravity. The height of the goods placed shall not exceed the designed packaging height of the stretch wrapping machine, otherwise it will affect the packaging effect and even damage the equipment; if the goods are too large and exceed the scope of the turntable, it shall be controlled within 100mm, and the placement position shall be adjusted according to the actual space of the equipment to avoid damaging the machine parts. At the same time, handle the goods with care to avoid collision with the chassis, prevent the chassis from deformation, and extend the service life of the machine parts.
二、（Operation Skills During Operation）
The standardization of operation during operation directly affects the packaging quality and equipment life. The core lies in parameter adjustment, tension control and operation monitoring, while avoiding common operational mistakes to improve packaging efficiency and effect.
1. Precise Parameter Adjustment
According to the size, weight, shape and packaging requirements of the goods, accurately adjust various parameters of the stretch wrapping machine, including the number of wrapping turns, turntable speed, lifting speed and film tension. For heavy and easily damaged goods, appropriately increase the number of wrapping turns (usually 2-3 more turns at the bottom and top), reduce the turntable and lifting speed, and increase the tension to ensure that the goods are tightly wrapped and improve transportation safety; for light and fragile goods, reduce the number of wrapping turns, increase the operation speed, and reduce the tension to avoid crushing and damaging the goods due to excessive tension.
In addition, the lifting, chassis and film frame drive of the stretch wrapping machine complete the speed change through the worm gear reducer, which must be used in accordance with the specifications: for the reducer with oil-immersed lubrication, the oil immersion depth must meet the requirements (if the worm is under or on the side of the worm wheel, it is the full tooth height of the worm; if it is above, it is 1/3 of the outer diameter of the worm; if there is an oil sight glass, it is 1/2 of the oil sight glass), and it is recommended to add 400ml of lubricating oil when the center distance a=63mm; the equipment must be replaced with new oil after 7-14 days of operation, and then once a year. When the ambient temperature is lower than 0 degrees, low-freezing-point lubricating oil must be used; the gear reducer adopts grease lubrication, which does not need frequent replacement and can be adjusted according to the actual situation.
2. Scientific Tension Control
Tension control is the core skill in the use of the stretch wrapping machine. Excessive tension will cause film tearing and goods extrusion deformation, while insufficient tension will lead to loose packaging, and goods are prone to shaking and damage during transportation. During operation, first set the medium tension, perform test packaging, observe the packaging effect, and then fine-tune the tension according to the actual situation of the goods. For irregularly shaped goods, segmental tension control can be adopted, increasing the tension at key parts (such as corners and center of gravity offset), and appropriately reducing the tension at flat parts to ensure uniform and firm packaging.
At the same time, avoid wrapping the film all the way to the bottom of the pallet, which will cause the forklift to damage the film when picking up the goods and lose the binding force. The correct approach is to make a tight cable a few inches from the bottom of the film, lock the load on the pallet, and avoid the forklift picking position, which not only ensures the fixing effect, but also avoids film damage.
3. Real-Time Operation Monitoring
During the operation of the equipment, the operator must monitor the whole process, observe whether the film output is smooth, whether the goods are placed stably, whether the turntable and lifting mechanism are running normally, and whether there is abnormal noise, jamming or abnormal sound. If the film is found to be torn, the equipment must be stopped immediately, check whether the film is installed correctly and whether the tension is too large, and restart after replacing the film; if there is abnormal noise, stop the machine for inspection, fasten loose parts or add lubricating oil, and contact professional personnel for maintenance if necessary. At the same time, pay attention to the remaining amount of film in time. When the film is about to be used up, stop the equipment in advance and replace it with a new film roll to avoid packaging interruption caused by film exhaustion and affect work efficiency.
In addition, the film tail must be properly handled to avoid the unfixed or too long film tail being stuck during the movement of the pallet, leading to film tearing and goods dumping. The film tail can be fixed by adjusting equipment settings, using automatic devices or film clips to ensure the integrity of the packaging.
三、Maintenance Skills After Shutdown
Correct maintenance after shutdown is the key to extending the service life of the stretch wrapping machine and reducing the incidence of faults. It is necessary to develop the habit of “maintaining immediately after shutdown”, focusing on cleaning, inspection and maintenance.
1. Equipment Cleaning
After shutdown, timely clean up the film debris, dust and stains on the surface of the stretch wrapping machine, focusing on cleaning key components such as the turntable, film frame and tension adjustment device, to avoid debris accumulation affecting equipment operation. When cleaning, use a dry cloth to wipe, avoid using water or corrosive cleaning agents to prevent rust and damage of equipment parts; at the same time, clean up the sundries around the equipment, keep the work area clean and tidy, and prepare for the next use.
2.Component Inspection and Maintenance
Check the tightness of each component of the equipment. If loose bolts and nuts are found, tighten them in time; check the lubrication of the film frame chain. If dryness and jamming occur, add lubricating oil; check the electrical cabinet, regularly clean and inspect electrical components and electrical connections, close the electrical cabinet to ensure the normal circuit of the equipment and avoid electrical faults. At the same time, check the film tension adjustment device to ensure that it can adjust the tension normally without jamming or damage. If the equipment is used continuously for 10-15 days, the chain tension must be adjusted to ensure smooth operation.
3. Consumable Storage
Store the unused stretch film properly, avoid direct sunlight and humid environment, prevent the film from aging and deterioration, and affect the packaging effect. When storing, place the film roll vertically to avoid extrusion and collision, and prevent the film from wrinkling and damaging; at the same time, store different specifications of film separately to facilitate quick access during the next use and improve work efficiency.
四、Common Fault Handling Skills
Mastering the handling skills of common faults can quickly solve problems, reduce equipment downtime, reduce production losses, and avoid aggravating faults due to improper operation.
1. Turntable Slows Down or Slips
If the turntable speed slows down or slips, first open the turntable motor cover, loosen the four connecting bolts on the reducer mounting plate, then adjust the two tension bolts evenly clockwise to reach the required tension; if the problem is not solved, check whether there is oil stain or sundries on the turntable surface, clean it and test again. If there is still an abnormality, check whether the motor or reducer is faulty and contact professional personnel for maintenance.
2. Film Breaks Frequently
Frequent film breakage is mostly caused by excessive tension, poor film quality or improper film installation. First, reduce the tension, perform test packaging, and observe whether there is still breakage; if the problem is not solved, check whether the film is damaged or aged, and replace it with high-quality and suitable machine-used stretch film; at the same time, check whether the film installation direction is correct and whether the film roll is loose, and restart after adjustment.
3. Lifting Mechanism Jams
The jamming of the lifting mechanism is mostly caused by dry chain, loose components or sundries blockage. First, stop the machine, turn off the power, clean up the sundries around the lifting mechanism, check the chain lubrication, and add lubricating oil; then check whether the bolts and nuts of the lifting mechanism are loose, and tighten them in time; if the jamming is serious, disassemble and check to see if any components are damaged, and replace the damaged components if necessary.
