Description
Technical Field
The invention relates to a double-sided machine of paperboard production equipment, in particular to a sectional conveying and heating double-sided machine which can improve the bonding speed and quality of surface paper (such as preprinted paper) and pitted paper.
Background
The development of production equipment of corrugated boards is closely related to the printing process, and the current preprinting mainly comprises three types:
1. offset preprinting: the printing quality is good, the plate making cost is low, the printing plate has low printing endurance, and solvent type printing ink which is not environment-friendly is selected.
2. Gravure preprinting: the printing quality is good, the plate-making cost is higher, the printing endurance is good, and solvent ink is selected.
3. Flexible printing and preprinting: the printing quality is good, the cost of the paperboard is low, the printing endurance is moderate, and the environment-friendly water-based ink for the carton is selected.
The three preprinting modes have advantages respectively, but the preprinting prospect of the flexo printing is wider in the long run, because the flexo printing can meet the quality requirements of customers with high-quality products, and the non-toxic and harmless carton water-based ink is used, so that the flexo printing conforms to the environmental protection trend and is beneficial to the health of consumers and front-line workers.
The preprinting is roll printing, the printed roll is used as the outermost paper on a corrugating machine, the preprinting outer paper and the pit paper coming out of the corrugating machine are adhered together through a double-faced machine, and the preprinting is suitable for large-volume color printing cartons.
However, the existing double-sided machine mainly has two paper feeding modes, one mode is that the printing layer of the pre-printed paper is downward during transmission, the printing layer is in sliding friction fit with a hot plate at the lower side of a hot plate channel of the double-sided machine, and the surface temperature of the printing layer is very high under the condition of high-speed transmission, so that a high-temperature-resistant film needs to be arranged on the surface of the printing layer of the pre-printed paper, and therefore, the cost is greatly increased; the high temperature resistant film is in sliding friction fit with the hot plate, and the high temperature resistant film can be scraped, so that the surface of the carton can generate poor wire drawing and scraping feeling.
The other is that the printing layer of the preprinting paper faces upwards during conveying, the printing layer moves synchronously with the conveying belt above the hot plate channel, so that the scratch is not easy to occur, but the derived problems are that the temperature of the upper side of the hot plate channel of the double-sided machine is not enough, so that the adhesion between the preprinting paper and the pitted paper is poor, and the drying efficiency of paste and the quality of the paperboard are influenced because the air permeability of the conveying belt is poor.
To sum up, need design a section can be suitable for the ink preprinting paper of low cost and sees the laminating of hole paper, does not influence both laminating, dry and solid efficiency, does not scrape the double facer of the ink preprinting paper printing layer of flower, assurance cardboard quality.
