It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0032] like Figure 1-5 As shown, the utility model provides a printing paper positioning clamp, including a printer body 1, a paper placement paper 2 is fixedly connected to the surface of the printer body 1, an output paper board 3 is fixedly connected to the surface of the printer body 1, a limiting device 4 is provided on the surface of the paper placement paper 2, and a knocking device 5 is provided on the surface of the paper placement paper 2.

[0033] The specific settings and functions of the limiting device 4 and the striking device are described in detail below.

[0034] like Figure 1 - Figure 5As shown, the limiting device 4 includes a mounting block 41, which is fixedly connected to the surface of the paperboard 2, and the surface of the mounting block 41 is rotatably connected with a bidirectional screw rod 42, and both ends of the bidirectional screw rod 42 are fixedly connected with a rotating wheel 43. The surface of the bidirectional screw rod 42 is threadedly connected with two limiting plates 44, and the two limiting plates 44 are slidably connected to the paperboard 2, and the distance between the two limiting plates 44 can be quickly adjusted, thereby completing the positioning and limiting of different papers, which is convenient for the placement and use of printing paper, increases the convenience when placing printing paper, and facilitates the use of the printer by the staff. The surfaces of the two limiting plates 44 are slidably connected with two sliding rods 45, and the ends of the two sliding rods 45 close to the paperboard 2 are fixedly connected with a pressing plate 48, and the surfaces of the two sliding rods 45 are covered with springs 46, and the two ends of the spring 46 are respectively fixedly connected to the sliding rod 45 and the limiting plate 44, through the pressing The addition of the plate 48, the spring 46 and the slide bar 45 can press the printing paper after the printing paper is placed, so that the printing paper will not move. The surface of the pressing plate 48 is rotatably connected to a plurality of rotating beads 49, and the plurality of rotating beads 49 are linearly arrayed on the surface of the pressing plate 48. The rotating beads 49 contact the surface of the printing paper, which can reduce the friction between the two, so that the printing paper will not get stuck when entering the printer body 1, which facilitates the use of the limit device 4. Both sides of the paperboard 2 are slidably connected with blocking plates 47, and the blocking plates 47 are "U"-shaped. The inner wall of the blocking plate 47 is fixedly connected to the limit plate 44. When the limit plate 44 adjusts the distance, the blocking plate 47 can block and limit the limit plate 44, so that the blocking plate 47 will not be driven by the bidirectional screw rod 42 to rotate, which facilitates the adjustment and use of the limit plate 44.

[0035] like Figure 2 and Figure 5As shown, the knocking device 5 includes two connecting blocks 51, and the two connecting blocks 51 are fixedly connected to the surface of the paperboard 2. The two connecting blocks 51 are rotatably connected to the side close to each other with a rotating shaft 52, and the surface of the rotating shaft 52 is fixedly connected with four knocking plates 53. Both ends of the rotating shaft 52 are fixedly connected with a cylinder 55, and the cylinder 55 is rotatably connected to the connecting block 51. The knocking plate 53 can knock on the surface of the printing paper to generate a slight vibration, so that multiple printing papers are separated from each other, which is convenient for printing and feeding. Use, further prevent the printing paper from entering the printer. Several sheets of printing paper are stuck together, which increases the service life of the printer. The surfaces of the four knocking plates 53 are glued with protective pads 54, which are made of sponge. Since the protective pads 54 are made of sponge, the knocking plates 53 will not damage the printing paper after knocking on the surface of the printing paper, which facilitates the use of the knocking device 5. A number of anti-slip strips 56 are fixedly connected to the surface of the cylinder 55, and the anti-slip strips 56 are arranged in a circular array on the arc surface of the cylinder 55. The anti-slip strips 56 can increase the friction between the staff and the cylinder 55, thereby facilitating the back and forth rotation of the cylinder 55.

[0036] The overall working principle is that when it is necessary to place the printing paper on the paperboard 2, the staff can rotate the rotating wheel 43, and the rotating wheel 43 can drive the bidirectional screw rod 42 to rotate, thereby driving the two limit plates 44 to move in the direction of approaching each other, and can adjust the distance between the two limit plates 44 to a distance suitable for the printing paper, and further place the printing paper between the two limit plates 44. There is an inclined plate on the surface of the limit plate 44, and the design of the inclined plate can assist in placing the printing paper, and further dock the printing paper between the two limit plates 44. At this time, the sliding rod 45 will be driven by the spring 46 to press the pressure plate 48 in the direction of the printing paper, which can simply limit the printing paper and make it difficult for the printing paper to move. At the same time, there is a rotating wheel on the surface of the pressure plate 48. The bead 49 contacts the surface of the printing paper, which can reduce the friction between the two, so that the printing paper will not get stuck when entering the printer body 1, which facilitates the use of the limit device 4. When it is necessary to adjust the position between the two limit plates 44, the wheel 43 can be further rotated. When the limit plate 44 is adjusting the distance, the blocking plate 47 can block and limit the limit plate 44, so that the blocking plate 47 will not be driven by the two-way screw rod 42 to rotate, which facilitates the adjustment and use of the limit plate 44. By setting the adjustment device, the distance between the two limit plates 44 can be quickly adjusted, thereby completing the positioning and limiting of different papers, facilitating the placement and use of printing paper, increasing the convenience of placing printing paper, and facilitating the use of the printer by the staff.

[0037] When the printer is printing, the staff usually places more printing paper on the surface of the cardboard 2. After placing it for a long time, the staff can rotate the cylinder 55, and drive the rotating shaft 52 to rotate through the cylinder 55, so as to drive the knocking plate 53 to knock on the surface of the printing paper. There is an anti-skid strip 56 on the surface of the cylinder 55. The anti-skid strip 56 can increase the friction between the staff and the cylinder 55, so as to facilitate the back and forth rotation of the cylinder 55, and there is a protective pad 54 on the surface of the knocking plate 53. Since the protective pad 54 is made of sponge material, the knocking plate 53 will not cause damage to the printing paper after knocking on the surface of the printing paper, which is convenient for the use of the knocking device 5. By setting the knocking device 5, the knocking plate 53 can knock on the surface of the printing paper to generate a slight vibration, so that multiple printing papers can be separated from each other, which is convenient for the printing paper to be loaded and used, and further prevents the printing paper from sticking together when entering the printer, thereby increasing the service life of the printer.
