What Is A Single Facer Machine？
If you don’t know what a single face corrugator is, then do you know corrugated boxes?
The single facer corrugation machine is a machine that produces corrugated paper.
The main components of the single facer are: base paper support, corrugating roller, pressure roller, preheating roller, gluing device, pneumatic device, paper guide and vacuum adsorption device, etc.
The single facer corrugated machine is an important equipment for producing the core paper of corrugated boxes. During production, the corrugated core paper is first heated, then the corrugated rollers are used to make the required corrugated shape, and finally the corrugated peak is coated with glue and bonded with the corrugated surface paper, to form single-sided corrugated cardboard.
The forming quality of corrugated cardboard has a lot to do with the correct use and maintenance of the corrugating single facer. Therefore, in the corrugated packaging industry, it is known as the heart of the “corrugated cardboard production line”.
What kinds of single facer machines are there?
We can supply the following types of single facer machines, and can also be customized according to the flute type you need：
1) Cassette type negative pressure single facer machine: The negative pressure design is adopted, with low heat loss, so that the core paper can be evenly pressed and attached to the surface of the corrugating roll, and the roll can be changed quickly. Effective width: 1800-2200mm
2) Cassette type positive pressure single facer corrugation machine: Fast cassette-type corrugating roll replacement, order adjustment at any time, automatic speed regulation, and automatic data storage. Effective width: 1800-2800mm
3) Adsorption type single facer: effective width: 1400-2500mm
4) Double corrugated single facer machine: one machine has two sets of corrugated rollers, one can be selected at will during work, and the other set is preheated and spared to replace the corrugated type. Small footprint (similar products need two single facer machines to achieve this function, which occupies a large area).
How does single facer machine works？
The corrugated core paper is heated first, and then the corrugated roll is used to form the required corrugated shape. Then, glue (starch adhesive) is applied to the corrugated peak and combined with the liner. The face paper and the formed corrugated paper are pasted into a two-layer corrugated cardboard at the tangent line of the pressure roller and the lower corrugated roller, and then are combined with other single corrugated cardboard and face paper through the traction belt on the flyover to the double-sided machine.
The heating methods of core paper include steam heating, electric heating and oil heating. The machining flute type of corrugated single facer can be UV/A, E, C, B, EB or customized according to needs.
Why the corrugated cardboard single facer is so important?
The operating process of the single facer machine includes the following: creating conditions for unwinding and manipulating the face paper and core paper; pre-processing and preheating the core paper and the face paper; preparing for corrugating and bonding processes; forming a straight core paper Specific corrugation; applying adhesive to the newly formed corrugation tip; bonding core paper and facial paper together; transporting the single-faced paper web to the conveyer bridge. If the single-faced paper web delivered to other processes has quality problems, the other processes cannot be repaired or compensated at all. Therefore, the single face machine is very important for carton production.
The quality of the corrugated board produced by the single face corrugated machine directly affects the production cost of the carton. Base paper is the main material for the production of cartons. About 75% of the cost of carton production comes from raw materials. If the corrugated board produced by the single facer is unqualified or defective, it means the waste of raw paper and other materials, the increase of production costs, and the decrease of production profits.
Therefore, in the increasingly competitive market environment of the carton industry, how important it is to choose the most suitable single facer machine, we will provide the best quality and service, and give the following guarantees:
- Using high-quality alloy steel raw materials to produce and process the machine
- Strict quality control of whole process
- Multiple machine testing process to guarantee the smooth working condition
- Professionals training the correct use and maintenance of the machine
