Through the spray plotter 3 of X axis, Y axis mobile can spray to printing material 5, and the rotary down pressure cylinder 43 in the four corners of printing material 5 can rotate and press the pressing plate 431 to printing material 5, and the adjust laying platform 4 can tighten printing material 5, prevent the spacing between spray plotter 3 and base 1 from being too small, and the interference between spray plotter 3 and printing material 5 forms paper jam phenomenon, and the reason that specifically can tighten printing material 5 is that the pressing plate 431 provides enough down pressure to printing material 5, and the friction between pressing plate 431 and printing material 5 is greater than the friction between printing material 5 and laying plate 45, when support plate one 41 and support plate two 42 move away, printing material 5 can be tightened.

[0025] Please refer to Figures 1-4In the embodiment, the adjusting laying platform 4 is movably arranged above the base 1 through the slide rail 44, the adjusting laying platform 4 can move along the Y-axis direction, the adjusting laying platform 4 comprises a support plate one 41 and a support plate two 42, the support plate one 41 is fixed with a laying plate 45 near the positive direction of the Y-axis, and the laying plate 45 is slidably arranged above the support plate two 42. The specific manner that the adjusting laying platform 4 can tension the printing material 5 is that the support plate one 41 and the support plate two 42 are independent of each other, and each of the support plate one 41 and the support plate two 42 clamps one end of the printing material 5 to tension the printing material 5. The support plate one 41 and the support plate two 42 comprise a position-avoiding groove 421, the laying plate 45 is installed in the position-avoiding groove 421, and the upper surface of the laying plate 45 is flush with the upper surfaces of the support plate one 41 and the support plate two 42. Through the arrangement of the position-avoiding groove 421, the height of the device is reduced to meet the needs of different production workshops. A pair of the rotating downward pressing cylinders 43 are arranged on the surface of the support plate one 41 near the positive direction of the Y-axis, and the rotating downward pressing cylinders 43 are arranged at intervals of the position-avoiding groove 421; another pair of the rotating downward pressing cylinders 43 are arranged on the surface of the support plate two 42 near the negative direction of the Y-axis, and the rotating downward pressing cylinders 43 are arranged at intervals of the position-avoiding groove 421. Through the arrangement of the rotating downward pressing cylinders 43 in the position-avoiding groove 421 of the support plate one 41 and the support plate two 42 respectively, the four corners of the printing material 5 can be conveniently pressed downward. The support plate one 41 and the support plate two 42 are respectively provided with positioning holes 422 near the two sides of the position-avoiding groove 421, the positioning holes 422 can be screwed into positioning columns 423, the positioning columns 423 are adhered with elastic films 4231 near the negative direction of the Z-axis, when the positioning columns 423 are screwed into the positioning holes 422, the elastic films 4231 can be attached to the base 1, and the positioning columns 423 do not protrude from the upper surfaces of the support plate one 41 and the support plate two 42. In order to fix the support plate one 41 and the support plate two 42 after tensioning the printing material 5, the positioning columns 423 are screwed and locked in the support plate one 41 and the support plate two 42 through bolt cooperation, the elastic films 4231 have anti-skid property and can prevent the support plate one 41 and the support plate two 42 from sliding relative to the base 1, and the elastic films 4231 have elasticity and can prevent the elastic films 4231 from loosening, thereby playing the role of elastic pads.

[0026] Please refer to Figures 3-5In the embodiment, the support plate one 41 and the support plate two 42 are manually pushed, the Teflon coating is attached to the position-avoiding groove 421 of the support plate two 42, and the Teflon coating is attached to the surface of the laying plate 45 in contact with the support plate two 42. The manual pushing can effectively reduce the manufacturing cost of the device to meet the purchase budget of small-scale spray printing companies. In order to make the manual pushing more labor-saving, the Teflon coating is attached to the surface of the laying plate 45 in contact with the support plate two 42 in the position-avoiding groove 421 of the support plate two 42, which reduces the friction and protects the support plate two 42 and the laying plate 45. The electric heating wire is arranged in the laying plate 45. The laying plate 45 heated by the electric heating wire can transfer heat to the printing material 5, which is paper. In order to make the ink sprayed by the spray machine 3 on the printing material 5 dry and solidify quickly, the electric heating wire is arranged in the laying plate 45, and the electric heating wire can also dry the printing material 5 which has not been sprayed and evaporate the moisture in the printing material 5. The printing material 5 placed in a humid warehouse for a long time will increase the moisture of the printing material 5 and make the printing material 5 soft.

[0027] When working, the staff first pushes the support plate two 42 together with the support plate one 41 to the negative direction of the Y axis, and then the staff controls the rotating down cylinder 43 on the support plate one 41 to rotate down, and the pressing plate 431 presses one side of the printing material 5. Then the staff moves the support plate two 42 to the positive direction of the Y axis, and the distance is that the side of the printing material 5 in the positive direction of the Y axis is in contact with the side of the support plate two 42 in the negative direction of the Y axis. At this time, the rotating down cylinder 43 on the support plate one 41 is controlled to rotate down, and the pressing plate 431 presses the other side of the printing material 5. Then, taking the pressing plate 431 on the support plate one 41 as the fixed end and the pressing plate 431 on the support plate two 42 as the moving end, the printing material 5 attached to the laying plate 45 is pulled tight, and the positioning column 423 is immediately locked into the positioning hole 422. The elastic film 4231 is locked tightly to the base 1 to prevent the support plate one 41 and the support plate two 42 from moving. At this time, the staff starts the device, and the Y axis moving frame 2 moves according to the program to carry the spray machine 3 to spray the printing material 5.

[0028] Through the above steps, the spray machine 3 which can move along the X axis and the Y axis can spray the printing material 5, the rotating down cylinder 43 located at the four corners of the printing material 5 can rotate and press the pressing plate 431 to the printing material 5, and the laying platform 4 can pull the printing material 5 tight to solve the problems of the complex structure of the paper jam prevention device of the existing spray machine, the large difficulty of factory assembly, and the poor deviation correction effect of the deviation correction roller.
