Description

Technical Field

[0001] The utility model generally relates to the field of printing technology, especially a printing device and a book. Background Art

[0002] With the development of printing technology and the improvement of people's aesthetic needs, the exterior design of books has become an important part of the publishing industry. Traditional book decoration methods mainly focus on beautifying the cover and illustrations, while the decoration of the fore-edge (the side opposite to the spine) is relatively less. To enhance the overall beauty and collection value of books, people have started to explore methods of adding decorative patterns to the fore-edge.

[0003] Currently, common fore-edge decoration techniques include screen printing and digital inkjet printing. Screen printing is a printing technology with a long history. By making patterns on a silk screen and then using ink to transfer through the screen onto the fore-edge, clear patterns are formed. Digital inkjet printing is a technology developed in recent years. It directly sprays ink onto the fore-edge through an inkjet printer to form patterns. Although these two technologies have been widely used in the field of book decoration, they cannot meet certain special requirements, such as showing patterns only under specific conditions or hiding patterns without damaging the overall beauty of the book.

[0004] The content in the background art part is only the technology known to the inventor and does not necessarily represent the prior art in this field. Summary of the Utility Model

[0035] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not used to limit the present utility model.

[0036] Figure 1 FIG. shows a schematic diagram of a printing device 100 according to an embodiment of the present utility model. Figure 2 FIG. shows another schematic diagram of a printing device 100 according to an embodiment of the present utility model. The following will be described in detail in conjunction with Figure 1 and Figure 2 for a detailed description.

[0037] As Figure 1 and Figure 2 shown, the printing device 100 includes a carrier plate 110, a conveying device 120, a book bending assembly 130, and a printing unit 140. The carrier plate 110 serves as a bearing component for providing an installation position and support for other components. The conveying device 120 is installed on the carrier plate 110 and is configured to convey books along a preset transmission path. For example, the conveying device 120 can convey books along the length direction of the carrier plate 110 (such as Figure 1 the first direction in). The book bending assembly 130 includes a first book bending rod 131 and a second book bending rod 132, and both the first book bending rod 131 and the second book bending rod 132 are arc-shaped rods. The first book bending rod 131 and the second book bending rod 132 are spaced apart above the carrier plate 110, and the centers of the arcs of the first book bending rod 131 and the second book bending rod 132 are located on the same side of the conveying device 120 (such as Figure 1(on the right side in the figure), a book bending area is formed between the first book bending rod 131 and the second book bending rod 132. The entrance of the book bending area is aligned with the transmission path, and the exit of the book bending area deviates from the transmission path, so that the conveying device 120 can send the book into the book bending area (that is, the conveying device 120 can send the book between the first book bending rod 131 and the second book bending rod 132). After the book enters the book bending assembly 130, the first book bending rod 131 and the second book bending rod 132 bend and deform the book. As the book bends, uniform displacement occurs between the inner pages of the book, and the fore-edge part of the book gradually unfolds (as Figure 1 shown), forming a surface to be printed. The printing unit 140 includes a print head 141 and a driving device 142 (only a part of the driving device 142 is shown in the figure). The print head 141 is arranged above the carrier plate 110, and the output end of the driving device 142 is connected to the print head 141. The driving device 142 is configured to drive the print head 141 to move. By performing a printing operation at the unfolded fore-edge through the printing unit 140, a hidden pattern can be formed at the fore-edge. This hidden pattern is hidden when the book is in a flat state (cannot be directly observed from the appearance of the book) and will only appear in a specific bending state.

[0038] According to an embodiment of the present invention, as Figure 1 and Figure 2 shown, the first book bending rod 131 is located inside the second book bending rod 132 (the side where the center of the arc is located is the inside). The second book bending rod 132 is higher than the first book bending rod 131, so that the second book bending rod 132 is closer to the fore-edge of the book, ensuring that the fore-edge can remain tight and not loose when unfolded, thus providing a stable and accurate surface to be printed for printing the hidden pattern, which is beneficial to improving the printing quality of the hidden pattern.

[0039] According to an embodiment of the present invention, as Figure 1 and Figure 2 shown, the diameter of the first book bending rod 131 is larger than the diameter of the second book bending rod 132. The first book bending rod 131 with a large diameter can provide more sufficient support for the book, ensuring that the fore-edge can remain tight and not loose when unfolded, thus providing a stable and accurate surface to be printed for printing the hidden pattern, which is beneficial to improving the printing quality of the hidden pattern.

[0040] According to an embodiment of the present invention, as Figure 1 and Figure 2 shown, the entrance width of the book bending area is larger than the exit width of the book bending area. So that after the book enters the book bending area, the first book bending rod 131 and the second book bending rod 132 gradually clamp the book, ensuring that the fore-edge can remain tight and not loose when unfolded, thus providing a stable and accurate surface to be printed for printing the hidden pattern, which is beneficial to improving the printing quality of the hidden pattern.

[0041] According to an embodiment of the present utility model, as Figure 1 and Figure 2 shown, a first support leg 151 can be provided between the first bent book bar 131 and the load plate 110, and a second support leg 152 can be provided between the second bent book bar 132 and the load plate 110. Among them, the first support leg 151 and the second support leg 152 can provide good support for the first bent book bar 131 and the second bent book bar 132, ensure the stability of the first support leg 151 and the second support leg 152, avoid unnecessary skew or movement of the book during the bending process, and ensure that the book opening can be evenly and precisely unfolded under the action of the first bent book bar 131 and the second bent book bar 132. Optionally, the second support leg 152 is a robotic arm, and the robotic arm can drive the second support leg 152 to move. The user can adjust the distance between the first bent book bar 131 and the second bent book bar 132 by manipulating the robotic arm to adapt to books of different thicknesses, ensuring that the best clamping effect and book opening unfolding state can be achieved regardless of the thickness of the book.

[0042] According to an embodiment of the present utility model, as Figure 1 and Figure 2 shown, the conveying device 120 can include a conveyor belt 121 and two clamping plates 122. Among them, the conveyor belt 121 is installed on the load plate 110 and is used to convey books in the first direction. The two clamping plates 122 are respectively arranged on both sides (left side and right side) of the conveyor belt 121, and the two clamping plates can limit the position of the book, prevent the book from falling off the conveyor belt 121, and also prevent the book from opening under the action of gravity. Optionally, one or more rollers are provided on the inner side (the side close to the conveyor belt 121) of the clamping plate 122 to reduce the friction between the book and the clamping plate 122 and make the movement of the book smoother.

[0043] According to an embodiment of the present utility model, as Figure 1 and Figure 2 shown, the printing unit 140 further includes an infrared detector 143. The infrared detector 143 is installed at the output end of the driving device 142. The infrared detector 143 and the nozzle 141 can move synchronously under the drive of the driving device 142. The infrared detector 143 is configured to detect the position and size of the book. Optionally, the driving device 142 is a multi-axis robotic arm.

[0044] According to an embodiment of the present utility model, as Figure 1 and Figure 2As shown, the printing device 100 further includes a rotating device 160. The rotating device 160 is configured to drive the carrier plate 110 to swing around a first axis to adjust the posture of the book (for example, adjust the unfolded book opening to a horizontal state), facilitating the printing unit 140 to perform printing at the book opening. Specifically, the rotating device 160 includes a base 161, a rotating motor 162, and a connecting frame 163. Among them, the base 161 is disposed below the carrier plate 110, the rotating motor 162 is mounted on the base 161, the output shaft of the rotating motor 162 is arranged along the first axis (the first axis is substantially parallel to the conveying direction (the first direction) of the conveying device 120), and the connecting frame 163 is connected between the carrier plate 110 and the output shaft of the rotating motor 162.

[0045] Compared with the prior art, an embodiment of the present invention provides a printing device 100. Among them, the conveying device 120 can smoothly feed the book into the book bending assembly 130. After the book enters the book bending assembly 130, two book bending rods (the first book bending rod 131 and the second book bending rod 132) cooperate to bend and deform the book. As the book bends, the book opening part of the book gradually unfolds. Through the printing unit 140, printing operations can be performed at the unfolded book opening, and a hidden pattern can be formed, endowing the book with a special decoration.

[0046] Figure 3 shows a side view of a book 200 according to an embodiment of the present invention. As Figure 3 shown, two hidden patterns are provided at the book opening of the book 200. When the book 200 is in a flat state, neither of the two hidden patterns can be directly observed from the appearance of the book 200. When the book 200 is bent forward towards the front cover by a certain angle, one hidden pattern appears. When the book 200 is bent backward towards the back cover, the other hidden pattern appears. Both of these two hidden patterns are formed by printing through the above-mentioned printing device 100. Specifically, when printing the one hidden pattern, the book 200 is bent forward towards the front cover; when printing the other hidden pattern, the book 200 is bent backward towards the back cover. Optionally, the graphic contour of the one hidden pattern is substantially the same as the graphic contour of the other hidden pattern to avoid interference between the two patterns and ensure the harmony and unity of the overall visual effect. Optionally, when printing the second hidden pattern (for example, the other hidden pattern), the corresponding white ink can be used for covering treatment according to the color depth of the first hidden pattern (for example, the one hidden pattern), and then, colored ink is sprayed to achieve the printing of the second hidden pattern, thereby avoiding visual conflicts or disharmony between the two patterns.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
