Problems solved by technology

[0005] In the actual working process, because the suction holes are generally tiny perforations, the adsorption area is small, and the suction is relatively concentrated. Wrinkles will still appear when printing soft printing media such as textiles and thermal transfer paper, which needs to be improved.

Embodiment 1

[0042] Such as figure 1 and figure 2 Shown, a kind of photo machine, comprises frame 1, is used for unwinding roller 2 of unwinding, is used to place the printing platform 3 of the printing medium that is discharged by unwinding roller 2, is used for printing printing assembly 4 and is used for The winding roller 5 of receiving material. One end of the unwinding roller 2 is provided with a first driving motor 6 for driving the unwinding roller 2 to rotate, and the first driving motor 6 is fixedly installed on the frame 1 . One side of the winding roller 5 is provided with a second driving motor 7 for driving the winding roller 5 to rotate, and the second driving motor 7 is fixedly installed on the frame 1 . The unwinding roller 2 unwinds the printing medium, and the printing medium is smoothly transported through the printing platform 3 , and is printed by the printing component 4 when passing the printing platform 3 , and then wound up on the winding roller 5 .

Embodiment 2

[0049] The difference between Embodiment 2 and Embodiment 1 is that, as Figure 6 As shown, in order to enable the printing medium to be transported more smoothly, both the winding roller 5 and the unwinding roller are located on the same side of the frame 1 , and the unwinding roller 2 is located above the winding roller 5 . The frame 1 is provided with a guide mechanism 26 for guiding the direction of printing materials. The guiding mechanism 26 is located on one side of the winding roller 5 . The guiding mechanism 26 includes a connecting plate 27 rotatably connected to the frame 1 and a guiding roller 28 parallel to the winding roller 5 . Two connecting plates 27 are provided and are respectively located at two ends of the guide roller 28 , and the guiding roller 28 is rotatably connected to the connecting plate 27 . There are three guide rollers 28 arranged in a triangular shape. The printing medium goes around three guide rollers 28 in turn and is wound up on the wind...

Embodiment 3

[0063] The difference between Embodiment 3 and Embodiment 1 is that, as Figure 8 As shown, in order to enable the printing medium to be transported more smoothly, both the winding roller 5 and the unwinding roller 2 are located on the same side of the frame 1 , and the unwinding roller 2 is located above the winding roller 5 . The frame 1 is provided with a tensioning mechanism 38 for tensioning the direction of the material. The tensioning mechanism 38 is located on one side of the winding roller 5 . Such as Figure 9 As shown, the tensioning mechanism 38 includes a first mounting plate 39 installed on both sides of the winding roller 5, a mounting groove 40 opened in the vertical direction on the side of the first mounting plate 39 facing the winding roller 5, and both ends are embedded. The tension roller 41 is arranged in the installation groove 40 . The inner wall of the installation groove 40 is provided with a rack 42 along the vertical direction, and the two ends o...

Abstract

The invention discloses a drawing machine. The drawing machine comprises a machine frame, an unwinding roller, a printing platform, a printing assembly, a winding roller and a second driving motor used for driving the winding roller to rotate, the printing platform is provided with a hollow bottom plate, the bottom plate is provided with suction holes communicated with an inner cavity of the bottom plate, an air pumping assembly used for pumping air in the bottom plate is arranged on one side of the printing platform, a containing groove is formed in the bottom plate, a diffusion plate is embedded in the containing groove, the upper end face of the diffusion plate and the upper end face of the printing platform are located on the same plane, a plurality of diffusion grooves are formed in the diffusion plate, the diffusion grooves and the suction holes are in matrix distribution, each diffusion groove corresponds to one suction hole, the sectional area of the diffusion grooves is largerthan the sectional area of the suction holes, and the suction holes are located in the diffusion grooves. Through the arrangement of the diffusion grooves, the contact area of the printing medium under the suction force is increased when the air suction assembly is vacuumized, so that the printing medium is kept in a flat state, the phenomenon that the printing medium is wrinkled and the like dueto the adsorption of a multi-point small area is avoided.

Description

technical field [0001] The invention relates to a printing device, in particular to a printing machine. Background technique [0002] The photo machine sprays inks of different color combinations to the inkjet printing medium through the nozzle to form the required pattern on the inkjet printing medium. The spray head is installed on the spray truck, which is driven by the spray truck to move laterally to spray in the width direction of the inkjet medium. [0003] In order to make the paper more smooth during the printing process, the existing photo machines are generally equipped with a pressure edge, so that the paper can enter the photo machine smoothly for printing. Existing photo machines, such as the patent application number CN201420871459.4, discloses a photo machine, including a frame; also includes a bottom plate and at least one pressing sheet; the bottom plate is installed on the frame; the pressing The sheet is arranged on the bottom plate with a gap between t...
