Description

Technical Field

[0001] The utility model relates to printing equipment, in particular to a stacking printing mechanism which is convenient for feeding materials. Background Art

[0002] Stacked printing allows for multi-color overprinting of printed substrates. To overprint both the front and back sides of a printed substrate, printing units need to be arranged vertically on both sides of the printing frame. In actual printing operations, after overprinting the front and back sides, the substrate needs to be pulled into an oven for heating so that the ink can dry quickly. Traditional stacked printing mechanisms have two ovens installed within the printing frame, one of which is located near one printing unit and the other near the other. With this arrangement of ovens, the substrate is pulled through a path where it first passes through one printing unit for overprinting on one side, then goes around to the first oven for heating and drying, and then is pulled through to the other printing unit for overprinting on the other side, and then goes around to the second oven for heating and drying. Only then can the printed substrate be pulled out of the printing frame. This complex material path affects the winding efficiency of printing, and also complicates the internal structure of the printing frame, making production, assembly, and maintenance inconvenient. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a stacking printing mechanism that is convenient for feeding materials and is used to solve the above problems.

[0004] To this end, the present invention is implemented by adopting the following scheme:

[0005] A stacked printing mechanism that is convenient for material feeding includes a printing frame, one side of the printing frame has a first printing unit arranged vertically, and the other side of the printing frame has a second printing unit arranged vertically. It is characterized in that the frame is provided with a first oven inside, the first oven is located between the first printing unit and the second printing unit, and also includes a second oven, the second oven is installed outside the printing frame, and the second oven is arranged corresponding to the discharge end of the second printing unit. When double-sided printing is performed, the printed substrate first passes through at least one first printing unit for printing on one side, and then passes through the first oven for heating and drying, and then passes through the remaining printing units for printing on the other side, and then is sent out of the printing frame and passed through the second oven for heating and drying; when single-sided printing is performed, the printed substrate passes through the required number of printing units for single-sided printing, and then is sent out of the printing frame and passed through the second oven for heating and drying.

[0006] The first oven is vertically arranged, and the height of the first oven corresponds to the arranged second printing units.

[0007] The above technical solution is a stacked printing mechanism that is convenient for material feeding. By arranging the second oven outside the printing frame, the substrate after double-sided printing or single-sided printing can be directly pulled out of the printing frame, and heated and dried in the second oven during the subsequent traction process, replacing the traditional structure in which both ovens are arranged inside the printing frame. It can effectively simplify the traction path of the printing substrate, facilitate the traction and winding of the printing substrate, and simplify the overall structure of the printing frame, facilitating its production assembly and subsequent maintenance operations.

[0013] As shown in the figure, the present invention discloses a stacked printing mechanism for convenient material feeding, comprising a printing frame 4, with first printing units 5 arranged vertically on one side of the printing frame 4 and second printing units 2 arranged vertically on the other side of the printing frame 4. A first oven 3 is disposed within the frame 4, located between the first printing unit 5 and the second printing unit 2. The first oven 3 is vertically arranged, and the height of the first oven 3 corresponds to the arrangement of the second printing units 2. The frame 4 also includes a second oven 6, which is mounted outside the printing frame 4 and corresponding to the discharge end of the second printing unit 2. When performing double-sided printing, the printed substrate 1 first passes through at least one of the first printing units 5 for printing on one side, then passes through the first oven 3 for heating and drying, then passes through the remaining printing units for printing on the other side, and then is discharged from the printing frame 4 and passed through the second oven 6 for heating and drying. When performing single-sided printing, the printed substrate 1 passes through the required number of printing units for single-sided printing, then is discharged from the printing frame 4 and passed through the second oven 6 for heating and drying.

[0014] When performing 3+3 double-sided overprinting, the material routing of the printing substrate 1 is as follows: Figure 1As shown, the printing substrate 1 first passes through three first printing units 5 for overprinting on one side, and then is pulled into the first drying oven 3 for heating and drying. Then, it passes through three second printing units 2 for overprinting on the other side. Finally, the printing substrate 1 is sent out from the printing frame 4 and passes through the second drying oven 6 for heating and drying. When performing 4+2 double-sided overprinting, the material routing of the printing substrate 1 is as follows Figure 2 As shown, the printing substrate 1 first passes through two first printing units for overprinting on one side, and then is pulled into the first drying oven 3 for heating and drying. Then, it passes through the remaining first printing unit 5 and three second printing units 2 for overprinting on the other side. Finally, the printing substrate 1 is sent out from the printing frame 4 and passes through the second drying oven 6 for heating and drying. When performing 5+1 double-sided overprinting, the material routing of the printing substrate 1 is as follows Figure 3 As shown, the printing substrate 1 first passes through a first printing unit 5 for printing on one side, then is pulled into the first drying oven 3 for heating and drying, and then passes through the remaining two first printing units and three second printing units 2 for overprinting on the other side. Finally, the printing substrate 1 is sent out from the printing frame 4 and passes through the second drying oven 6 for heating and drying. When performing 6+0 single-sided overprinting, the material routing diagram of the printing substrate 1 is as shown in FIG. Figure 4 As shown, a printed substrate 1 is subjected to single-sided overprinting by three first printing units 5 and three second printing units 2. The printed substrate 1 is then conveyed from a printing frame 4 and passed through a second drying oven for heating and drying. It should be noted that the number of first and second printing units shown in the figure is merely illustrative, and any desired number of first and second printing units can be provided based on overprinting requirements.

[0015] The structure of the present invention, by arranging the second oven 6 outside the printing frame 4, enables the substrate after double-sided printing or single-sided printing to be directly pulled out of the printing frame and heated and dried in the second oven during the subsequent pulling process, replacing the traditional structure in which both ovens are arranged inside the printing frame. It can effectively simplify the pulling path of the printing substrate, facilitate the pulling and winding of the printing substrate, and simplify the overall structure of the printing frame, making it easier for its production, assembly and subsequent maintenance operations.
