The positioning pin 32 passes through the coupling hole 33 and is screwed with the positioning hole 31.

The baffles 2 are moved along the width direction of the support plate 11, so that the distance between the two baffles 2 is changed to adapt to the width of the current printing stock. Then, the positioning bolt 32 passes through the connecting hole 33 and is in threaded connection with the positioning hole 31, so that the baffle 2 is positioned.

A first conveyor roller 41 and a second conveyor roller 42 are rotatably connected to the frame 1, and a conveyance path is formed between the first conveyor roller 41 and the second conveyor roller 42. The first conveying roller 41 and the second conveying roller 42 are arranged in parallel and turned in opposite directions. The first conveying roller 41 and the second conveying roller 42 are both driven by a motor. The first conveying roller 41 and the second conveying roller 42 are rotated in opposite directions, so that the first conveying roller 41 and the second conveying roller 42 respectively abut against the upper surface and the lower surface of the printing stock, and the printing stock is conveyed to the supporting plate 11 and located between the two baffle plates 2 by the action of friction force.

The frame 1 is rotatably connected with a support shaft 5 by a motor (not shown in the figure), and the support shaft 5 is horizontally placed and positioned above the support plate 11. The motor can drive the support shaft 5 to rotate positively and negatively. A support rod 51 is fixed on the support shaft 5, a vacuum suction cup 52 is fixedly connected to the lower end of the support rod 51, and a vacuum pump (not shown in the figure) is arranged on the machine frame 1; the vacuum chuck 52 is connected to a vacuum pump through a pipe. After the printing stock is placed on the support plate 11, the vacuum pump is started, and the printing stock is adsorbed on the vacuum sucker 52 to realize positioning.
