In addition to the bag, the packaging carrier of the packaging machine
also has the form of a box.
There are several types of box packaging machines according to different packaging forms. Let's take a look.
The upper and lower membranes of the continuous pull hard box packaging machine adopt sheet membrane, the upper membrane uses composite membrane, the lower membrane uses stretch membrane, and the lower membrane directly pulls out the box with strong bearing capacity.
Specifically, it is driven by the clamping of the chain to enter the molding mold, and the molding inside the molding mold is formed by adding temperature and air pressure to pull the lower film out of the required box shape, the product to be packaged in the pendulum area (Through the feeding device)
Put it into a stretched box, enter the sealing mold as the chain runs forward, and attach the upper film to the lower film in the sealing mold, it can be set to seal, vacuum, inflate, etc. according to different functional requirements, and then seal the upper and lower membranes together.
Then exhaust, reduce the mold, the packaged products continue to run forward, first through the mobile code system to print each product production date.
The products are horizontally cut into a single row in the cross-cutting area, and then the products are vertically cut by a longitudinal cutting device so that each product is individually formed.
The device also adds a Cursor Alignment Color film system to save costs for users.
Configure waste scrap recycling suction barrel system for users to maintain environmental sanitation.
The material placing device of the equipment is fixed at the front end of the material placing area of the machine.
The flat plate of the device is composed of 30 Hopper boxes corresponding to the boxes stretched out of the packaging film, which is equivalent to 30 quantitative cups on the inner flat plate. When working, the materials are first placed on one side of the storage area on both sides, the material is dialed to the opposite storage area through manual or mechanical dial plate, and the material automatically fills the Hopper box (
Each Hopper box is basically a capacity of about 50 grams)The excess material is moved to the storage area on the other side.
At this time, the valve plate is opened, and the material automatically falls into the groove of the packaging film to realize automatic filling.
Body-fitted box packaging machine covers the product and the bottom plate after the packaging film is heated. The bottom plate uses the box as the carrier, and the packaging will be more beautiful.
At the same time, vacuum suction is enabled under the bottom plate, and the body film is formed according to the shape of the product and pasted on the bottom plate (Color printing paper card, corrugated cardboard or bubble cloth, etc)On.
Its studio size is fixed. After packaging, the product is tightly wrapped between the body film and the bottom plate!
The small internal pumping vacuum packaging machine uses negative pressure to pump out the air in the vacuum chamber, but the body-fitted vacuum packaging machine uses positive pressure, which has the advantages of good adhesion and beautiful appearance of the packaged products.
The continuous body-fitted box packaging machine is a model that can realize automatic cutting and automatic work. Compared with the front body-fitted box packaging machine, the equipment has a larger volume and a length of about 4 meters, at the same time, there is no need for manual cutting, which is more prominent in saving labor.
The semi-automatic box-type packaging machine adopts composite fresh-keeping gas to replace the air in the plastic bag or packaging box that has been loaded into the food, and changes the gas ratio in the plastic bag or packaging box, form a micro-controlled atmosphere in the bag or box-That is, a miniature air conditioner was formed.
According to the actual needs of customers, a certain proportion of O2 CO2 N2, O2 CO2, O2 CO2 mixed gas can be filled into the package, thus prolonging the shelf life of food and improving the value of food.
The main purpose of the full-automatic box packaging machine is to realize automatic packaging. The machine body can be equipped with automatic box dropping, automatic filling, blanking, code spraying and other automatic mechanisms.
The full-automatic box packaging machine reduces manual operation through chain pushing box and conveyor belt clamping box.
The above is the working principle of various box packaging machines, and their packaging effects are not the same.
Users need to consider according to their own requirements and hope to be helpful to you.
