[0025] The pressing roller mechanism 6 includes a support arm 61 and an L-shaped plate 63. One end of the support arm 61 is fixedly connected to the frame 1, and an electric push rod 62 is fixedly installed below the other end of the support arm 61. The output end of the electric push rod 62 faces vertically downward, and the output end of the electric push rod 62 is fixedly connected to one end of the L-shaped plate 63. A pressing roller 64 is rotatably installed inside the other end of the L-shaped plate 63. The pressing roller 64 is located above the guide roller 5.
