[0020] Reference Figure 1-4 A stone plastic box printing machine comprises a processing table 1, the top of the processing table 1 is rotatably connected to a conveyor belt 2, and a printing section 3 and a drying section 4 are also arranged on the top thereof, a flipping member 5 is arranged in the drying section 4, the flipping member 5 is used to flip the stone plastic board and cooperate with the drying section 4 to perform double-sided printing on the stone plastic board, the flipping member 5 comprises a pair of flipping plates 51 and an adjusting component 6 for adjusting the distance between the pair of flipping plates 51.

[0021] It is worth mentioning that the stone plastic box usually needs to be folded before printing. Considering that the traditional printing operation can only print on one side because the stone plastic box is folded, the turning member 5 is used to turn the stone plastic board and then cooperate with the drying part 4 to perform double-sided printing.

[0022] A pair of conveyor belts 2 are driven on the top of the processing table 1 by a pair of motors, and the flip plate 51 is arranged between the pair of conveyor belts 2 .

[0023] Furthermore, the printing unit 3 includes a pair of printing frames 31 fixedly installed on the top of the processing table 1, and a roller frame 33 is slidably connected to the printing frame 31 through a T-bar 32, and a printing roller 34 is rotatably connected to the roller frame 33. A spring 35 is provided on the outer periphery of the T-bar 32, and the two sides of the spring 35 are respectively fixedly connected to the side surfaces of the printing frame 31 and the T-bar 32.

[0024] It should be noted that the roller frame 33, under the action of the T-bar 32 and the spring 35, drives the printing roller 34 to press down to print the stone plastic board, wherein an ink box is fixedly installed on the top of the printing frame 31, and the ink box provides ink to the printing roller 34 for printing.

[0025] Furthermore, the drying section 4 includes a pair of drying boxes 41 fixedly installed on the top of the processing table 1, an air cavity 42 is provided inside the pair of drying boxes 41, and a guide plate 43 is fixedly installed below the air cavity 42 and above the flip plate 51, the guide plate 43 is communicated with the air cavity 42, and a heating element 44 is fixedly installed inside it, a fan 45 is fixedly installed on the top of one of the drying boxes 41, and the fan 45 is communicated with the pair of air cavities 42 through an air pipe 46.

[0026] In detail, the advantage of providing the guide plate 43 is that the hot air heated by the heating element 44 can be used to dry the printed stone plastic board, thereby preventing the stone plastic board from being contaminated by ink due to the ink not drying up after the stone plastic board is turned over by the turning plate 51.

[0027] In more detail, the flip member 5 also includes a rotating shaft 52, wherein a pair of the flip plates 51 are rotatably connected in one of the drying boxes 41 via the rotating shaft 52, a motor 53 is fixedly installed on the periphery of the drying box 41, and the shaft end of the motor 53 is fixedly connected to the rotating shaft 52, the flip plate 51 is a circular structure, and a plurality of through grooves 54 are penetrated on its side, and the through grooves 54 can be inserted into the stone plastic board.

[0028] In general, the adjustment assembly 6 includes a double-headed screw 61, a guide groove 62 passing through both sides is provided in the rotating shaft 52, and the double-headed screw 61 is rotatably connected in the guide groove 62, and a pair of flip plates 51 are provided with a guide block 63 slidingly connected to the guide groove 62 at the center point, and are respectively threadedly connected to the two ends of the double-headed screw 61.

[0029] Finally, the other end of the double-headed screw 61 is threadedly connected to a locking nut 64 and fixedly mounted with a hand wheel 65 . The locking nut 64 can be pressed against the side wall of the rotating shaft 52 .

[0030] The specific operation is that the motor 53 drives the rotating shaft 52 to drive a pair of flip plates 51 to rotate to flip the stone plastic board, and after the stone plastic board is dried and turned over, it passes through the conveyor belt 2 at the other end for double-sided printing;

[0031] The locking nut 64 is used to press against the side wall of the rotating shaft 52 to fix the double-headed screw 61 to prevent it from rotating with the rotating shaft 52. The double-headed screw 61 is rotated by the handwheel 65 to drive a pair of flip plates 51 to rotate in opposite directions.

[0032] Working method: When working, the distance between the pair of flip plates 51 is adjusted by rotating the double-headed screw 61 through the hand wheel 65, and then the locking nut 64 is rotated to fix the double-headed screw 61, and then a plurality of stone plastic boxes are placed on the conveyor belt 2 at the first end and conveyed to the printing roller 34 for printing. After printing, the stone plastic boxes are inserted into the through slot 54 under the action of the conveyor belt 2, and the motor 53 drives the rotating shaft 52 to indirectly drive the pair of flip plates 51 to rotate;

[0033] Then, the stone plastic board is dried and turned over under the action of the turning plate 51 and the drying box 41, and then the stone plastic board comes to the conveyor belt 2 at the other end for transportation, so as to achieve the effect of double-sided printing.
