What are the reasons for the problems in the products produced by bubble film machines?
Bubble film machine is a type of anti pressure, moisture-proof, and shockproof chemical product machine used for packaging and filling. Its products are applied to the outer packaging of electronic instruments, household appliances, handicrafts, glass products, handicrafts, bicycles, and other items. But some production packaging problems may occur, resulting in unusable packaging. So what are the reasons for this?
1. The low extrusion temperature results in poor resin plasticization, resulting in poor transparency of the bubble film after machine blow molding. The solution is to increase the extrusion temperature appropriately to ensure that the resin can be uniformly plasticized;
2. In order to solve the problem of unstable film bubbles caused by the large blowing expansion ratio of the product, which can swing back and forth from left to right and easily cause wrinkles, it is necessary to appropriately reduce the blowing expansion ratio of the bubble film machine;
3. Adjusting the cooling device to ensure uniform air flow at the air outlet can achieve uniform film thickness. Therefore, when the air supply volume around the cooling air ring is inconsistent, resulting in uneven cooling effect, adjustment is necessary.

Precautions for operating bubble film machines
An important point of the bubble film machine is that when operating the machine, the operator cannot stand directly in front of the machine to avoid accidents and damage to the operators. And during feeding, it is strictly prohibited to transfer metal impurities and other hard objects that may damage the machine into the barrel. When operating a rotating machine, it is prohibited to wear gloves to prevent injury caused by being drawn in by the machine.
Secondly, before operating the bubble film machine, it is necessary to check and add the lubricating oil in the gearbox and air compressor, and check the lubrication of the mechanical rotating components to avoid damage to the machine and noise caused by excessively dry parts. At the same time, it is necessary to check whether the wiring of each power supply is disconnected or leaking, and whether the instrument is damaged. Before operation, the safety and normal operation of each component should be ensured to avoid production accidents.
Furthermore, it is necessary to increase the molding temperature, cooling air temperature, and blowing expansion ratio within the film-forming conditions. And when the discharge of the membrane buckle is uniform, it is necessary to wear gloves to slowly pull the tube blank, and at the same time, close the port, slightly open the intake control valve, so that a small amount of compressed air can be inserted into the center hole of the core rod. Then, carefully guide it through the stable foam frame and the herringbone plate, and thread it into the traction roller and guide roller until it is rolled. The compressed air pressure for blowing and expanding the tube blank should be appropriate, so as not to cause the tube blank to rupture, but also to ensure the symmetry and stability of the membrane tube, which relatively ensures the quality of production.
Finally, after the operation is completed, when it is necessary to clean the extruder and die, copper knives, rods, or compressed air can be used for cleaning work, but do not damage the surface of the screw and screw, and maintain a smooth and clean surface.
