How to troubleshoot common faults in 3D transparent film packaging machines

Three-dimensional Transparent film packaging machine The common faults mainly include positional deviation, inability to overlap long sealing positions, failure of the sealing film to complete properly, and insufficient precision. So... Three-dimensional Packaging machinery equipment How can we solve these problems? Let me introduce you.

1. During the operation of the three-dimensional transparent film packaging machine, if the long-seal position of a single box is closed while the film position shifts, this can cause the long-seal position to shift or result in failure to seal properly.

Problem Analysis and Solution: This issue may occur only in individual boxes, rather than affecting all boxes. This is because the cutting blades on the blade holder have become dull, or the blades are not properly aligned to ensure a clean cut. The boxes are packaged inside a larger container. When the film isn't completely severed, tension can cause it to tear, leading to misalignment of the film's position. To resolve this, you’ll need to resharpen the cutting blades or adjust the position of the top metal wire at the back of the cutter so that there’s no gap between the blades, allowing the film to be cut cleanly and directly in one pass.

2. Three-dimensional Transparent film packaging machine After running for a period of time, the cut film will become shorter, the long sealing areas will narrow, or the long sealing areas may fail to overlap properly, making it impossible to complete the film wrapping. Problem analysis and solution: The three-dimensional transparent film packaging machine pulls the film down through frictional rotation between the rubber roller and the optical axis in the knife holder. Because a gap has formed between the rubber roller and the optical axis, the film is cut shorter than before, resulting in insufficient film tension. The position of the optical axis in the knife holder is fixed, so the rubber roller needs to be adjusted. Tighten the fixing screws on both sides of the rubber roller toward the optical axis to bring the rubber roller closer to the optical axis; this will restore the proper length of the film roll.

3. How to improve the film-feeding speed and accuracy of a three-dimensional transparent film packaging machine.

Problem Analysis and Solution: The packaging speed is related to the mechanical structure and also depends on the dimensions of the packaging box. Currently, 3D transparent film packaging machines available on the market are quite fast even for small models, but they fall short when it comes to larger boxes.

4. Three-dimensional Transparent thin packaging machine What is the typical thickness of commonly used packaging materials?

Problem Analysis and Solution: Most of the materials used in three-dimensional transparent film packaging machines are... BOPP cigarette film typically has a standard thickness of 2 to 2.5 filaments, though a thickness of just 2 filaments is sufficient. When selecting packaging materials, key considerations include the film’s shrinkage rate, brightness, and static electricity properties.
