Commonly used classification methods are classified according to the packaging process, which can be divided into main packaging machinery and auxiliary packaging machinery. Packaging machinery that completes packaging processes such as wrapping, filling, and filling is called the main packaging machine, or packaging host; packaging machinery that completes the washing, drying, testing, stamping, metering, conveying, and stacking operations is called auxiliary Packaging Machinery.
(I) Wrapping and Packaging Machinery
Wrapping and packaging machinery is used to pack bulk products. According to the different processes of wrapping, it can be divided into kink packaging machines, end folding packaging machines, pillow packaging machines, envelope packaging machines, stretch packaging machines and so on.
(II) Filling and packaging machinery
Filling and packaging machinery is used to pack powdery and granular solid articles. Filling and packaging machinery includes direct filling and packaging machines and bag-making filling and packaging machines. The direct filling and packaging machine uses pre-formed paper or plastic bags for filling, and can also fill directly into other containers. The bag-making filling and packaging machine is a packaging machine that needs to complete both the process of forming a container and filling the product into a container.
(Three) filling and packaging machinery
Filling and packaging machinery is used to pack fluid and semi-fluid items. According to the process of filling products, it can be divided into normal pressure filling machine, vacuum filling machine, pressure filling machine and so on. Filling and packaging machinery is usually connected with a sealing machine, a labeling machine, etc. to become a mechanized filling line.
(Four) sealing machinery
The sealing machine is suitable for the sealing of various packaging containers. According to the different sealing processes, it can be divided into glass jar capping machines (gland, screw caps, etc.), bag sewing machines, box sealing machines, plastic bags and paper bags.
(5) Labeling machinery
Labeling machines are machines used to affix label paper or labels to packages.
(Six) strapping machinery
The bundling machinery includes a band bundling machine, a wire binding or a rope bundling machine, and the like.
(VII) Cooked Forming Packaging Machinery
Cooked molding packaging machinery is divided into blister packaging machines and skin packaging machines according to different processing techniques.
(Eight) vacuum packaging machinery
Vacuum packaging machines are divided into vacuum packaging machines and inflatable packaging machines according to whether they can be filled with inert gas after evacuating.
(9) Shrink packaging machinery
Shrink packaging machines include small shrink packaging machines that can be used as single-product or multiple-product sales packages, as well as large shrink packaging machines that can be used for transport packaging including pallet packaging.
(10) Other packaging machinery
In addition to the above types of packaging machinery, there are bottle washing and drying machines, packaging materials and specifications testing machines, stamping machines, measuring machines, etc. These single machines are generally combined with other packaging machines into a packaging unit.
Common packaging machinery:
(I) Bag Filling, Sealing and Packaging Machine
The main processes of bag making, filling and sealing packaging machine are forming, filling, sealing and cutting of packaging bags. The packaging materials used are mainly film products, such as plastic films, paper, lead foil and composite films.
(Two) thermoforming packaging machinery
Thermoforming packaging machines are divided into blister packaging machines and skin packaging machines according to the different packaging container forming processes. Blister packaging is currently the most widely used packaging. It is a packaging method that seals the product between the pre-formed blister and the bottom plate. Skin packs are similar to blister packs. The difference between the two is that skin packs are used as forming dies, and blister packs are shaped by special dies. The skin-packing can keep the product stationary, so that the product quality can not be damaged by collision with each other during the circulation process.
Shrink packaging machinery is a packaging machinery that uses stretch-oriented heat-shrinkable film to package articles (or inner packaging), and then heats the film appropriately to shrink the film and tightly wrap the article (or inner packaging). Shrink the film The upper and lower rolls are tensioned, and the product machine parts are pushed to the film. After the film wraps the product, the three sides of the film are sealed by the sealing member, and then conveyed by the conveyor belt. The heating device prevents the product from being wrapped and is cooled to form a shrink packaging Pieces.
