Referring to fig. 1 to 3, a lottery printing terminal according to an embodiment of the present invention includes a bottom case 11, a flip cover assembly 12, a printer assembly 2, and a roll paper shaping device 3. The bottom case 11 has a receiving groove 11a for receiving the roll paper 4, a receiving groove 11b for receiving the roll paper shaping device 3, and a mounting groove 11c for receiving the printer assembly 2, and the receiving groove 11a, the receiving groove 11b, and the mounting groove 11c are sequentially communicated in the paper discharge direction of the roll paper 4 (the arrow direction in the drawing is the paper discharge direction of the roll paper 4). The flip component 12 is pivotally connected to the bottom shell 11 and can be turned to open and close relative to the bottom shell 11. The roll paper shaping device 3 comprises a shaping member 31 and a shaping wiper blade 32, the shaping member 31 being mounted on the side of the cover member 12 facing the bottom shell 11, i.e. the shaping member 31 rotates with the cover member 12. The shaping doctor blade 32 is transversely arranged on the bottom shell 11 and is positioned above the accommodating groove 11b, the shaping component 31 comprises a supporting arm 311 and a buffer arm 312 which are arranged back and forth along the paper outlet direction of the printing roll paper 4, an included angle is formed between the supporting arm 311 and the buffer arm 312, when the flip component 12 is covered on the bottom shell 11, the supporting arm 311 and the buffer arm 312 are respectively arranged on two opposite sides of the shaping doctor blade 32, and the printing roll paper 4 sequentially slides around the supporting arm 311, around the shaping doctor blade 32, around the buffer arm 312 and is arranged in the printing area of the printer component 2 along the paper outlet direction when the flip component 12 is covered on the bottom shell 11.

In the lottery ticket printing device provided by the embodiment of the invention, the printing roll paper 4 is placed in the accommodating groove 11a, and a section of the printing roll paper is pulled out to sequentially pass through the accommodating groove 11b and the mounting groove 11c along the paper outlet direction, and finally placed in the printing area of the printer assembly 2. When the flip cover assembly 12 is pivoted to cover the bottom case 11 around the pivot point, the roll paper 4 sequentially slides around the supporting arm 311, around the shaping blade 32, and around the buffer arm 312 in the paper-discharging direction. In this way, the drawn portion of the roll paper 4 is shaped straight in the opposite direction of the roll paper 4 after being wound by a plurality of winding points, so that the probability of the roll paper 4 being blocked at the ticket outlet is greatly reduced, and the printer assembly 2 is convenient for printing.
