[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Moreover, a first feature being "above", "above" and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0030] refer to Figure 1-3 An embodiment of the present application shows an elliptical printing machine with an extra-flat printing platform, including a printing platform body 11 arranged below the print head of the elliptical printing machine, the top of the printing platform body 11 has a horizontal support surface 111, and at least one rotatable guide wheel 12 is provided on both sides of the printing platform body 11, and the guide wheel 12 rotates around a horizontal axis, and the horizontal axis is perpendicular to the material conveying direction on the elliptical printing machine, and the highest point of the guide wheel 12 is higher than the support surface 111.

[0031] In short, by providing a printing platform body 11 under the printing head of the oval printing machine, the printing platform body 11 can support the platen 41, so that the platen 41 maintains a high flatness when printing under the printing head; in addition, Figure 3 As shown, when the table 41 is slightly tilted due to gravity or other reasons, the guide wheel 12 is used to guide the table 41 so that the slightly tilted table 41 can be smoothly moved to the top of the printing table body 11 to avoid interference between the table 41 and the side of the printing table body 11.

[0032] For details of the above scheme, please refer to Figure 3 The distance between the highest point of the guide wheel 12 and the support surface 111 is L, and L is 1-3 mm. The width of the printing platform body 11 is preferably matched with the width of the platform 41. Figure 3As shown in FIG. 1 , when the platen 41 moves to the left and enters the range of the top of the printing table body 11, the platen 41 does not contact the guide wheels 12 on both sides, and the bottom of the platen 41 abuts against the support surface 111 of the printing table body 11; when printing is completed, the platen 41 continues to move to the left, and after the platen 41 moves a short distance, the platen 41 contacts the guide wheels 12 on both sides. Figure 3 The guide wheel 12 on the left side of the table 41 is slightly lifted, so that there is a gap between the table 41 and the supporting surface 111 of the printing platform body 11, thereby reducing the friction between the table 41 and the printing platform body 11 and facilitating the table 41 to move away from the printing platform 1.

[0033] In some embodiments, the guide wheel 12 is vertically adjustable on the side of the printing platform body 11 .

[0034] Specifically, Figure 2 As shown, the printing platform 1 further includes a mounting frame 13, on which a horizontal rotating shaft 131 is provided, and the guide wheel 12 is rotatably provided on the horizontal rotating shaft 131; the mounting frame 13 is also provided with a vertically opened strip hole 132, and the side of the printing platform body 11 is provided with a connecting hole 112, and a screw (not shown) is connected between the strip hole 132 and the connecting hole 112 to achieve the fixing of the mounting frame 13 on the side of the printing platform body 11. In other words, the screw passes through the strip hole 132 and is threadedly connected to the connecting hole 112, and the nut of the screw presses the mounting frame 13 on the side of the printing platform body 11.

[0035] Specifically, Figure 1 As shown, in this embodiment, three guide wheels 12 are respectively disposed on each side of the printing platform body 11 .

[0036] In addition, if Figure 4 and Figure 5 As shown, an embodiment of the present application shows an elliptical printing machine, including a machine base 2, an elliptical track 3 arranged on the machine base 2, a moving device 4 slidably arranged on the elliptical track 3 to convey a workpiece, a printing head (not shown), and any one of the above-mentioned printing platforms 1, the moving device 4 includes a moving trolley 42 and a table 41 arranged on the moving trolley 42, and the moving trolley 42 is slidably connected to the elliptical track 3.

[0037] Conventionally, in the prior art, a crossbeam is provided and the thickness of the table 41 is set to alleviate the tilting of the table 41, but the high flatness requirement cannot be achieved and the overall structure of the mobile device 4 is relatively bulky. In this embodiment, the printing platform 1 is provided so that the table 41 is horizontally supported when printing under the print head, so that the table 41 can achieve a very high flatness when printing. At the same time, due to the provision of the printing platform 1, the structure of the mobile device 4 is optimized, and the practice of providing a crossbeam at the bottom of the table 41 in the prior art is omitted, and the thickness requirement of the table 41 is reduced, so that the structure of the mobile device 4 is lighter, which is beneficial to improving the operating efficiency of the mobile device 4.

[0038] It should be noted that, compared with the prior art, the moving device 4 in this embodiment omits the crossbeam. Although this may cause the table 41 to incline more severely during movement, due to the guide wheels 12 on the printing platform 1, the table 41 can be smoothly moved to the top of the printing platform body 11, thereby achieving extremely flat printing.

[0039] In the above scheme, if Figure 5 As shown, the mobile trolley 42 is provided with two groups of pulleys 421, one group of pulleys 421 includes two pulleys 421, and the outer periphery of the pulleys 421 is formed with a ring-shaped recessed structure, and the two pulleys 421 in each group of pulleys 421 on the mobile trolley 42 are clamped on both sides of the elliptical track 3; the mobile trolley 42 is provided with a transmission gear block 422, and the elliptical printing machine also includes a driving assembly (not shown) that is transmission-connected to the transmission gear block 422. Among them, the matching mode of the mobile trolley 42 and the elliptical track 3, and the transmission mode of the transmission gear block 422 and the driving assembly can all adopt the existing technology.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
