Foam net is a new type of flexible packaging material, widely used in the packaging of glass products, precision instruments, and various fruits due to its unique expandable mesh structure and elastic foam net film. The production process flow is as follows: raw materials enter the extruder - foaming agent is injected - anti shrinkage agent is injected - self die extrusion - cooling and shaping - traction - cutting. The foam net sleeve machine can produce plastic net products for various purposes, suitable for extrusion of various high-pressure, low-pressure, polypropylene and other raw materials, and can also be used for product packaging in various industries such as fruits, garlic, flowers, industrial products, and daily necessities.
However, there are also many precautions when using a foam net sleeve machine: when abnormal or discolored molten plastic is found, or the product becomes brittle, the temperature should be adjusted to confirm whether the heating ring temperature sensing line is working properly, and the screw and adhesive head components should be checked for damage. To prevent foreign objects from falling into the barrel and damaging the screw and barrel, and to prevent metal fragments and debris from falling into the hopper. If processing recycled materials, a magnetic hopper should be added to prevent iron filings from entering the barrel.
Check the heating temperature of the mesh machine to avoid inaccurate temperature gauges. Check and confirm if the gap between the glue roller and the glue is parallel. Then, the pressure gauge must reach the pressure, otherwise the pressure may not be solid and affect the product. Confirm whether the laminating machine equipment is in a safe state. Clean up the debris on the rubber roller to prevent it from entering the finished product and causing waste.
The manufacturer of the net sleeve machine pointed out that the adjustment of film conveying should make the film tension uniform to adapt to the size of the film conveying tension. Turn on the main power switch, turn on the heating cylinder and motor, then turn on the oil pump, adjust the flow rate of the laminating adhesive, and adjust the parallelism between the rollers. Adjust the positioning of the paper feeding table, apply the laminating adhesive, and at the same time turn on the drying channel for heating.
Do not start the machine when the barrel has not reached the preset temperature. Newly opened electric heating generally requires the temperature to reach the set value for 30 minutes before operating the screw. The manufacturer of the net set machine pointed out that during the overall operation and debugging, the main focus is on adjusting the continuity of the body's operation and the quality of the labeling of each set of fixtures. If the labeling of some sets of fixtures is not aligned with the sample, adjust the fixture position first, and if it is not possible, fine tune the fixture.
