[0030] The upper paper guiding assembly 60 comprises an upper paper guiding plate 61, an auxiliary frame 62 and a plurality of groups of upper paper guiding rollers 63. The connecting piece 90 penetrates the front end of the upper paper guiding plate 61 and the front end of the lower paper guiding plate 51 simultaneously. Thus, the upper paper guiding plate 61 can rotate around the lower paper guiding plate 51. The upper paper guiding plate 61 comprises a second horizontal section 611, a second inclined section 612 arranged behind the second horizontal section 611, a guide plate 613 arranged at the two sides of the second inclined section 612, and a limiting plate 614 arranged behind the second inclined section 612. The auxiliary frame 62 is installed on the second horizontal section 611 of the upper paper guiding plate 61. Each group of upper paper guiding rollers 63 comprises an upper adjusting shaft 631 and an upper roller 632 installed on the upper adjusting shaft 631.

The positioning rod 81 passes through the matching holes 6131 of the two guide plates 613 and the two ends of the positioning rod 81 extend from the two sides of the two guide plates 613. The pressing member 82 comprises a sleeve 821, a top block 822 slidingly arranged in the sleeve 821, a spring arranged in the sleeve 821, a guide strip 823 passing through the sleeve 821 and arranged on the top block 822. The spring is arranged in the sleeve 821 and abuts against the rear side of the top block 822. The front side of the top block 822 extends from the sleeve 821. The two sides of the sleeve 821 are provided with long limiting holes 824. The guide strip 823 passes through the limiting holes 824 from the outside and is arranged on the top block 822. The front side of the top block 822 is provided with a pressing groove 825 matched with the positioning rod 81.

[0032] During assembly, the pressing members 82 are arranged side by side on the limiting plate 614. The spring abuts against the top block 822 forwardly. The top block 822 further abuts against the positioning rod 81. When the positioning rod 81 is pressed upwardly, the positioning rod 81 moves to the top position in the matching hole 6131. When the positioning rod 81 is released, the top block 822 presses the positioning rod 81 to the bottom position in the matching hole 6131 under the action of the spring.

[0033] During installation of the label paper, the upper paper guide assembly 60 is turned upwardly. The label paper passes between the lower paper guide assembly 50 and the upper paper guide assembly 60. The positioning rod 81 is further pressed upwardly. The upper paper guide assembly 60 is pressed downwardly on the lower paper guide assembly 50 until the positioning rod 81 moves to the rear position of the clamping groove 71 of the limiting piece 70. The label paper is clamped between the belt 53 and the upper roller 632. The driving motor 54 drives the belt 53 to feed the paper. When the positioning rod 81 is released, the top block 822 presses the positioning rod 81 to the bottom position in the matching hole 6131 under the action of the spring. At the same time, the two ends of the positioning rod 81 arranged on the upper paper guide plate 61 are clamped into the clamping groove 71 of the two limiting pieces 70. The pressing member 82 keeps the positioning rod 81 clamped in the clamping groove 71 to prevent the positioning rod 81 from falling off the clamping groove 71. Thus, the lower paper guide assembly 50 and the upper paper guide assembly 60 are kept in a pressed state.

[0034] When the upper paper guide assembly 60 needs to be opened, the positioning rod 81 is pressed upwardly. The positioning rod 81 moves to the top position in the matching hole 6131. At the same time, the two ends of the positioning rod 81 arranged on the upper paper guide plate 61 are withdrawn from the clamping groove 71 of the two limiting pieces 70. The upper paper guide plate 61 is further turned upwardly away from the one end of the connecting piece 90.
