Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

As shown in Figure 1, a printing machine with an automatic winding device includes a frame 1 and a controller 2 installed on the frame, and an unwinding device 3, a composite device 4, and a curing device are sequentially installed on the frame 1. Device 5, cooling device 6, peeling device 7 and winding device 8 and conveying device 9.

As shown in Figure 2, a printing press with an automatic winding device, the winding device 8 includes a motor 81, a rotating shaft 82 and a winding roller 83 sleeved on the rotating shaft 82, on the winding roller 83 A left retaining ring 810 and a right retaining ring 811 are sleeved, and a mobile device 812 is installed on the left and right retaining rings 810, 811. The mobile device 812 is controlled by the controller 2, and the rotating shaft 82 is connected to the winding roller 83 through a bearing. Rotationally connected, a gear 84 is sleeved on one end of the rotating shaft 82, a friction plate 85 is provided between the gear 84 and one end of the winding drum 83, and the output shaft of the motor 81 is connected to the gear 84 on one end of the rotating shaft 82. The other end of the rotating shaft 82 is threadedly connected with an adjusting nut 86, and between the adjusting nut 86 and the end of the take-up roller 83, a rotating disc 87 and a compression spring connected to the rotating shaft 82 are arranged in turn. 88.
