The principle of a stretch film vacuum packaging machine is to use a forming mold. First, the film is heated, and then the forming mold is used to shape the container. Then, the packaging material is loaded into the formed lower film cavity, and then vacuum packaging is carried out. Today, we will introduce the precautions to be taken when using a stretch film vacuum packaging machine.

1. Before starting up, check if the compressed air pressure meets the requirements (above 0.6 bar), and check if all primary components are intact, such as heating belts, scissors, and various components of the car. At the same time, check for other personnel around the machine to ensure safety after startup.

2. Open up the CIP cleaning system and perform pre production cleaning on the feeding system and measuring machine to ensure product cleanliness.

3. Turn on the main power air switch, turn on the power to start up, set and check the temperature of each temperature controller, apply the film, adjust the color code, apply the coding ribbon, and determine whether the coding date and related characters match the products produced on that day.

4. First, adjust the bag making and check the coding effect, while opening the feeding system for feeding. When the material meets the requirements, first open the bag making mechanism bag, and at the same time check the vacuum degree and heat sealing quality of the vacuum box extraction. That is, after the bag making meets the requirements, start filling the material and start production.

5. During the production process, the quality of the product should be checked at any time, such as whether the basic requirements of the product, such as mouthwash, vacuum degree, heat sealing line, wrinkles, and weight, are qualified. If there are any problems, adjustments should be made at any time.

6. Operators are not allowed to arbitrarily adjust some operating parameters of the machine, such as the number of runs, various parameters of servo and frequency conversion. If adjustments are needed, it is necessary to report to the section chief, and relevant repair or technical personnel can adjust them simultaneously; In production, operators can adjust the temperature and some phase angle parameters of each temperature controller according to the actual situation, but it is necessary to inform the team leader and section chief first to ensure that all parameters of the equipment operation are controlled throughout the production process, ensure the safe and stable operation of the equipment, and ensure normal production and product quality.

7. If there is a problem with the equipment or product quality during production, the machine should be shut down immediately to handle the problem. It is prohibited to handle problems during machine operation to prevent safety accidents from occurring. If you are unable to handle or have a significant problem, immediately inform the team leader that the repair personnel will handle it simultaneously, and hang a safety warning sign that says "under maintenance, no startup". It is necessary for operators and repair personnel to handle the problem simultaneously, in order to solve the problem quickly and resume production.
