Mobert develops integrated production line

In order to improve the appearance of frozen food bags, Mobert has recently developed an integrated production line that can seal, pre-cut and roll the bags onto the core board. The length of the freezing bag is generally 300-500 mm. A freezer bag roll is made of 20-50 frozen bag rolls. If the roll core plate is not used, the appearance may be indecent.

In fact, this is exactly the situation where the elastic film used in the kitchen was in the past. The industry has long launched a roll core board to enhance the texture and thickness of the freezer bags and improve their appearance. In other words, psychological factors play an important role in facilitating customers to make purchase decisions because the increased size increases the product's texture. From a business perspective, products become more attractive.

The model has its own uniqueness. At present, the existing models of the market are mostly operated through dual tracks, but this model uses four-track operation and is suitable for the above specific purposes. When dual-track machinery is used, it is inconvenient to produce frozen bags. Due to the increase in extrusion costs and decoration costs, freezer bags must be sold at higher prices to ensure profitability. In this case, in addition to labor costs, the operation also requires the addition of special machinery.

In order to develop a system that facilitates the introduction of the core board, not only a large amount of technology has been put in, but also the entire coil system and the final part have been redesigned.

The production line is equipped with a set of electric automatic centering roll seats. In other words, instead of relying on the spindle, the film roll can be lifted by two moving arms. When it is lifted to the correct position, the film will automatically roll off.

In the process of unwinding, cutting the sealing blade cuts the film roll into 4 parts, and the blade can also be cut and sealed longitudinally at the same time. The four rail grooves (also foldable) formed are sealed by the pre-cut unit (knurling). The above two steps are carried out at the same time, so all bags can be kept at a certain distance between the first step and the second step, thereby reducing production waste and product defects. The machine is also equipped with a set of anti-stretching devices to ensure optimal sealing even at high speeds.

The production line can reach a decoiling speed of 150 meters per minute. However, when other models reach this speed, the quality of the product will be affected, and the quality of the packaging bag cannot be guaranteed because this key step involves the introduction of the core board. The machine is equipped with a set of compensating pressure rollers. The pressure roller ensures the optimal roll speed according to the speed of the sealing device. The volume is divided into three parts: the first step is to take the packaging bag on the core board, the second step is to form a roll, and the third step is to remove the film roll. The winding of the packaging bag is done mechanically, wherein a device is used to introduce the packaging bag into the winding core plate, pull down the first packaging bag, lock it by inert principle, and no adhesive is needed.

When the counter detects that a pre-determined number of bags has been wound, a personalized tape (sometimes glue) can seal the film. Finally, technical data reports will be made. The production line can reach the production speed of 1000 bags per minute, which is equivalent to 250 rpm (sealing and pre-cut) for each rail tank.
