In other embodiments, the distance measuring sensor 135 measures the vertical distance of the printing substrate above the first positioning plate 132 / second positioning plate 133, and takes the vertical distance as the height of the printing substrate.

[0038] According to an embodiment of the present application, as shown in Figure 1 and Figure 2As shown, the gilding workbench 130 can further include a second linear actuator 136, which can be, for example, an electric push rod, a pneumatic cylinder or a hydraulic cylinder, or the like driving device capable of realizing linear motion. The second linear actuator 136 is connected with the first positioning plate 132 and is configured to drive the first positioning plate 132 to reciprocate along the first direction, which enables the first positioning plate 132 and the second positioning plate 133 to clamp and position different numbers / thicknesses of the printing matter, thereby meeting the processing requirements in different scenarios. In other embodiments, the second linear actuator 136 can be connected with the second positioning plate 133 and configured to drive the second positioning plate 133 to reciprocate along the first direction.

[0039] According to an embodiment of the present application, as shown in Figure 1 and Figure 2 As shown, the gilding workbench 130 can further include an outer frame 137 for providing mounting positions and stable support for other components of the gilding workbench 130.

[0040] According to an embodiment of the present application, as shown in Figure 1 and Figure 2 As shown, the conveying device 120 can include an unwinding roller 121, a first deflection roller 122, a second deflection roller 123 and a winding roller 124 arranged in sequence on the rack 110 along the conveying path. The unwinding roller 121 can be a driving roller or a driven roller, which is mainly used for mounting and releasing the gilding film roll; the first deflection roller 122 and the second deflection roller 123 are located at the middle section of the conveying path and are used to guide the gilding film to change the running direction, so that the gilding film is conveyed along the first direction between the first deflection roller 122 and the second deflection roller 123; the winding roller 124 is a driving roller, which is mainly used for winding the used gilding film. Preferably, the conveying device 120 can further include a tensioning roller 125 for adjusting the tension of the gilding film, so as to ensure the stability of the gilding film during conveying.

[0041] According to an embodiment of the present application, as shown in Figure 1 and Figure 2As shown, the book mouth digital gilding equipment 100 can further include a rolling roller 180, which is arranged above the gilding workbench 130 and is configured to be rotatable about a first axis. The main function of the rolling roller 180 is to roll the printing material to ensure the flatness of the book mouth, thereby providing a high-quality surface for the subsequent gilding process and ensuring the uniformity and consistency of the gilding effect. Specifically, before the gilding operation starts, the gilding workbench 130 can be driven by the linear driving device 170 to move in the first direction. During this process, the gilding workbench 130 carries the printing material to pass under the rolling roller 180, which applies moderate pressure to the book mouth of the book for rolling treatment. This preprocessing step can effectively eliminate wrinkles or unevenness on the surface of the book, ensure that the printing surface is closely attached to the gilding film during the gilding process, and thus significantly improve the gilding quality. Preferably, the rolling roller 180 is located upstream of the digital gilding print head 140, so that the surface of the printing material has been sufficiently rolled before gilding printing, thereby improving the working efficiency and gilding quality of the equipment.

[0042] According to an embodiment of the present application, Figure 1 and Figure 2 As shown, the book mouth digital gilding equipment 100 can further include an electrostatic generator 190, the output end of which is coupled to the rolling roller 180. In this way, the rolling roller 180 can adsorb and remove impurities such as debris and dust on the surface of the printing material under the action of static electricity, thereby ensuring that the printing surface is cleaner and more tidy, reducing gilding defects caused by surface impurities, and improving gilding quality.

[0043] Compared with the prior art, the embodiment of the present application provides a book mouth digital gilding equipment 100 which can perform precise gilding operation on the book mouth of a book, solving the problems of difficult positioning, incomplete graphics and text, high cost and long time consumption of template gilding in traditional flat-press gilding. Specifically, the digital gilding print head 140 can heat and print the gilding film according to the pre-stored graphics and text information, which can be modified at any time, thereby meeting the needs of small-batch production and personalized design at low cost. The visual positioning device 150 can use machine vision technology to accurately determine the relative position of the printing material and the digital gilding print head 140, ensuring the precise alignment of the gilding graphics and text printed by the digital gilding print head 140 with the book mouth of the book; the linear driving device 170 drives the gilding workbench 130 to move in the first direction, in combination with the rolling action of the rolling wheel 160 on the gilding film, to ensure the integrity and consistency of the gilding graphics.

[0044] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments.
