How does the fully automatic stretching film vacuum packaging machine work

The fully automatic stretching film vacuum packaging machine adopts a continuous step-by-step method, which is formed by the lower roll film and sealed by the upper roll film. The packaging process is automatically completed by machines, and filling can be done manually or mechanically as needed. The lower roll film is pulled and stepped at a fixed distance. It passes through the preheating zone and heating zone, and is formed by air pressure, vacuum or stamping. After filling the filling zone with materials, it enters the heat sealing zone. In the heat sealing zone, the upper roll film is covered on the forming box after passing through the guide roller. Depending on the packaging needs, vacuuming or filling with protective gas can be carried out, followed by hot pressing and sealing. After the heat sealing is completed, the production batch and date can be sprayed. After transverse and longitudinal cutting, the finished packaging product is formed. The cut edge material can be collected and cleaned by suction barrels or winding devices.

Preparation before use of the machine:

Before starting the equipment, the forming molds for the upper and lower films should be installed. After that, the upper and lower films should be installed. After the equipment is started, the chain should be in working state and the film should be moved according to the set parameters, in steps according to regulations, and at regular intervals. Take a few steps to see if the formed film is relatively stable before placing the product.

The specific workflow is as follows: the lower film is first heated and stretched inside the forming mold to form the same groove as the mold (the forming mold can be changed according to requirements), then moved forward to the feeding area for manual placement. After moving forward to the sealing mold, the equipment automatically vacuums, inflates, seals, and deflates, and then moves forward to the transverse cutting area. Through the cooperation of the upper and lower knives, the airbag is pressurized, The transverse cutting knife divides each row of products horizontally, and then runs forward to the disc longitudinal cutting knife. The longitudinal cutting knife divides each product vertically, making it a single product. Then each product enters the subsequent process through the feeding hopper. The membrane waste on both sides is sucked into the waste bucket through the waste suction system equipped with the equipment.

This machine can package cooked products, frozen products, grains, garlic rice, meat products, bean products, snack foods, frozen fresh meat, seafood, and various electronic components of equipment. It can achieve the goals of oxygen isolation, moisture resistance, mold resistance, corrosion resistance, and extend the shelf life and preservation period.

One of the characteristics of the fully automatic continuous stretching film vacuum packaging machine is that the equipment has multiple functions. This machine can balance the use of soft and hard film quality, and can set different steps to meet the packaging efficiency of different products during operation. After changing the mold, the equipment can also package different products; This machine has various forms of packaging, such as vacuuming, adding nitrogen or mixed gas after vacuuming, and only used for product sealing.

The entire machine has a 304 food grade stainless steel frame structure, so the equipment does not deform; The components are made of all stainless steel standard finished products, and the molds are carved from finished aluminum plates, with a collection of high-quality craftsmanship.

Packaging items come in from one end and come out from the other end, making it easy to form a streamlined production line. The appearance of the packaging is beautiful and the shelf display effect is good. Due to two vacuuming cycles and the installation of an oxygen free gas flushing device between the two vacuuming cycles, the deoxygenation effect can be further improved, the shelf life can be extended, and the packaging quality can be improved.

Due to the use of hot forming method to form packaging containers, it is easy to achieve multiple parallel operations, which is much shorter than the production cycle of packaging machines using prepared packaging containers. The cycle time can be between 2s and 6s, and the number of cycles can be between 10 to 30 times per minute. Can pack hundreds of pieces per minute.

There are various forms of packaging containers, such as box shaped, disc shaped, cup shaped, circular, square, etc. The size of the packaging container can also be determined according to needs. For larger containers, one to two pieces can be formed at a time, while for smaller containers, several pieces, a dozen pieces, or even more can be formed at a time, depending on the actual size of the packaging.

Each machine of this fully automatic stretching film vacuum packaging machine is equivalent to a packaging system. Except for manually loading and unloading the packaging material supply device with film and sometimes requiring manual or partial filling, all other tasks are automatically and continuously completed, resulting in extremely high productivity.
