[0009] See also Figure 1 to Figure 2The slide 61 is movably arranged on the workbench 1 and can move relative to the workbench 1. The slide driving member 62 is arranged on the workbench 1 and connected to the slide 61 to drive the slide 61 to move. The printing transfer wheel 63 and the printing wheel 6 are rotatably arranged on the slide 61 and can rotate relative to the slide 61. The rotating shafts of the printing transfer wheel 63 and the printing wheel 6 are parallel, and the wheel surfaces of the two are in contact. The moving direction of the slide 61 is perpendicular to the central axis of the printing wheel 6. The slide 61 is provided with a printing wheel driving member 60 for driving the printing wheel 6 to rotate. The printing wheel driving member 60 is preferably a motor. When the printing wheel driving member 60 is started, the printing wheel 6 and the printing transfer wheel 63 rotate together, and the pigment on the wheel surface of the printing transfer wheel 63 is transferred to the printing wheel 6. When the workpiece is brought into contact with the wheel surface of the printing wheel 6, printing can be performed on the workpiece. The wheel surface of the printing wheel 6 has an inwardly concave groove, and the groove cannot print a pattern on the workpiece, so the printing wheel 6 can print stripes on the workpiece.

[0010] The workbench 1 is also provided with a first rubber-coated roller 81, a mobile rubber-coated roller 84, a second rubber-coated roller 82, a reciprocating screw 88, a swing rubber-coated roller 85 and a third rubber-coated roller 83, all of which have rotating shafts parallel to the rotating shaft of the printing wheel 6. The roller driving member 8 is arranged on the workbench 1, and is used to drive the first rubber-coated roller 81 to rotate. The first rubber-coated roller 81 is connected to the second rubber-coated roller 82 through a belt transmission, driving the second rubber-coated roller 82 to rotate. The second rubber-coated roller 82 is connected to the reciprocating screw 88 through a belt transmission, driving the reciprocating screw 88 to rotate. The swing rubber-coated roller 85 is rotatably arranged on the connecting block 87, and a nut that cooperates with the reciprocating screw 88 is arranged on the connecting block 87. The reciprocating screw 88 rotates, driving the nut that cooperates with it to move back and forth on the reciprocating screw 88, and the swing rubber-coated roller 85 moves with the connecting block 87 and can rotate relative to the connecting block 87. The third rubber-coated roller 83 is rotatably arranged on the workbench, and the swinging rubber-coated roller 85 is between the second rubber-coated roller 82 and the third rubber-coated roller 83, and is in contact with the second rubber-coated roller 82 and the third rubber-coated roller 83. The second rubber-coated roller 82 drives the swinging rubber-coated roller 85 to rotate, and the swinging rubber-coated roller 85 drives the third rubber-coated roller 83 to rotate, and the pigment on the second rubber-coated roller 82 is transferred to the third rubber-coated roller 83 through the swinging rubber-coated roller 85. The movable rubber-coated roller 84 is rotatably arranged on the roller moving seat 89, and the roller moving seat 89 is movably arranged on the workbench 1. The roller moving driving member 86 is preferably a cylinder, which is connected to the roller moving seat 89 and is used to drive the roller moving seat 89 to move. The mobile rubber-coated roller 84 is between the first rubber-coated roller 81 and the second rubber-coated roller 82, and can move back and forth between the position of contacting the first rubber-coated roller 81 and the position of contacting the second rubber-coated roller 82, so as to transfer the printing pigment on the first rubber-coated roller 81 to the second rubber-coated roller 82. A pigment groove for holding the printing pigment is provided below the first rubber-coated roller 81, and the first rubber-coated roller 81 carries the pigment on itself by rotating. The transfer path of the pigment is the pigment groove, the first rubber-coated roller 81, the mobile rubber-coated roller 84, the second rubber-coated roller 82, the swinging rubber-coated roller 85 and the third rubber-coated roller 83.

[0011] The slide 61 moves toward the third rubber-coated roller 83, so that the printing transfer wheel 63 contacts the third rubber-coated roller 83, and the pigment on the third rubber-coated roller 83 is transferred to the printing wheel 6 through the printing transfer wheel 63. The slide 61 moves away from the third rubber-coated roller 83, so that the printing wheel 6 contacts the workpiece, and the pigment on the printing wheel 6 is printed on the workpiece. The printing wheel automatically switches between the two positions of receiving pigment and printing through the movement of the slide, first receiving the pigment, then printing, then receiving the pigment, and then printing. It can automatically and infinitely print, with a good degree of automation and high production efficiency. The utility model automatically and stepwise transfers the printing pigment from the pigment tank to the printing wheel, so that the pigment is transferred between multiple rubber-coated rollers, and the pigment finally transferred to the printing wheel is more uniform, and the printing quality is better.
