Description

Corrugated board making equipment with digital inkjet pre-printing unit

technical field

The invention belongs to the field of corrugated cardboard manufacturing equipment, and relates to a corrugated cardboard manufacturing equipment with a digital ink-jet type pre-printing device.

Background technique

In the prior art, there are mature corrugated cardboard manufacturing equipment. Corrugated cardboard is mainly used to make corrugated cartons. There are two methods for making this kind of cartons. One is that the corrugated cardboard manufacturing equipment itself is equipped with corresponding slotting and cutting devices, which can process the base paper in one time Corrugated cartons (referring to the unfolded shape of cartons), the other is to first produce corrugated cardboard from base paper through corrugated cardboard manufacturing equipment, and then separately go to groove, cut and process into corrugated cartons; Both need to have corresponding characters, symbols or graphics. The corrugated cartons produced by the aforementioned two methods do not have corresponding characters, symbols or graphics on the surface paper, so it is necessary to use a printing machine to print the surface of the corrugated cartons. Printing on the surface of the paper, because it needs to exert a certain pressure on the corrugated cardboard during printing, it will cause a certain loss in the strength of the corrugated cardboard, which will drop by about 20%. Graphics are printed on paper, and then pasted on the surface paper of corrugated boxes by machinery or by hand. This method is complicated in process, high in cost and low in efficiency; The text, symbols or graphics are carved out of the template, and then the template is spread on the surface paper and painted or sprayed manually. This method is not only low in efficiency, poor in quality, but also pollutes the environment; The text, symbols or graphics are pre-printed on the roll paper with a traditional printing machine, and then the printed roll paper is used to make corrugated cardboard in the production line, and finally processed into a corrugated box. This method has better Excellent printing quality and production quality can improve processing efficiency, especially suitable for mass production, but generally more than 10,000 cartons are required. The biggest disadvantage is that it is not suitable for the production of small batches of corrugated cartons because the cost is too high.

Contents of the invention

The technical problem to be solved: replace the traditional printing machine with digital inkjet printing, and overcome the shortcomings of the existing technology in corrugated cardboard pre-printing; the inkjet printer can be easily integrated with the corrugated cardboard manufacturing equipment, that is Without affecting the overall process of corrugated cardboard production equipment, the base paper can be processed into corrugated boxes in one batch, and the equipment has the function of corrugated cardboard pre-printing. At the same time, the requirements for processing quantity are very flexible, and it can process small batches of corrugated boxes. Pre-printed processing is performed with high efficiency, good quality and low cost.

The technical solution adopted:

Corrugated cardboard production equipment with digital inkjet pre-printing device has the basic structure of general corrugated cardboard production equipment: including the rotation of the roll surface paper 1 and the transmission mechanism 2 and 3, the rotation mechanism of the roll core paper 8 9. Corrugating roller 10 and transmission mechanism 11, rotation of roll bottom paper 12 and transmission mechanism 13 and 14, gluing mechanism 15, drying mechanism 16, slotting and cutting mechanism 17 and 18, characterized in that: Make the front end of equipment, the position before the first drive roller 4 of roll face paper or slotting mechanism 17 is equipped with digital ink-jet type pre-printing device, and this device has ink-jet printer 5 with computer control.

Beneficial effects: The corrugated board making equipment can be pre-printed, so as to further tap the potential of the equipment. Compared with the process of pre-printing corrugated boards with traditional printing machines, there is no need for plate making, not only high processing efficiency, good quality, and low cost. Low, especially the requirement for the processing quantity is very flexible, it can be easily applied to the processing of small batches of corrugated boxes, and the printing format can range from tens of millimeters to several meters, with a wide range of applications; using ultraviolet (UV) curing inkjet The technology can be used not only for paper pre-printing, but also for pre-printing of polymer material sheets and films, and can be sun-proof, waterproof, non-inking, and non-bleaching.

Detailed ways

Further explain in detail in conjunction with accompanying drawings;

The arrows in the accompanying drawings indicate the paper running direction;

As shown in Figures 1, 2 and 3, the digital inkjet pre-printing device is installed at the front end of the corrugated cardboard manufacturing equipment, that is, the starting end of the face paper 1, specifically before the first driving roller 4 of the face paper 1 or slotting In the position before the mechanism 17, the inkjet printer 5 is positioned at the front side of the facial paper 1, and it is necessary to ensure that its print head 6 has an adjustable distance from the front surface of the facial paper 1 in operation.

As shown in Figure 3, when the inkjet printer 5 uses UV inkjet technology to print, an ultraviolet curing lamp 7 must be installed on the digital inkjet type pre-printing device, and the lamp should ensure that the ultraviolet rays can evenly irradiate the printed surface paper 1 on.

The so-called digital ink-jet pre-printing device refers to a device that can complete the pre-printing function on the facing paper 1 with the ink-jet printer 5 controlled by a computer as the core. It is necessary to make, input or Store it in the computer, and then instruct the inkjet printer to print on the face paper 1.

The so-called UV inkjet technology refers to: the ink that can be cured by ultraviolet radiation is used as the ink used in inkjet printing. This ink must be cured by ultraviolet radiation and can be used on any material (paper, polymer) Printing on substrates can be sun-proof and waterproof, so it can significantly improve the printing quality in pre-printing of corrugated boards.
