[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a printing paper positioning structure. Figure 1-3 A printing paper positioning structure includes a positioning frame 1, one side of the positioning frame 1 is fixedly connected to a control box 2 by bolts, the inner cavity side wall of the positioning frame 1 is rotatably connected to two groups of bidirectional threaded rods 3 by a rotating shaft, one end of the two groups of bidirectional threaded rods 3 close to the control box 2 rotates through the positioning frame 1 and extends to the inside of the control box 2, one end of the two groups of bidirectional threaded rods 3 passing through the positioning frame 1 is provided with a brake, and the brake is arranged inside the control box 2, the surface of the two groups of bidirectional threaded rods 3 is threadedly connected to two groups of support frames 4, and the bottom of the two groups of support frames 4 is rotatably connected to a plurality of groups of rotating wheels 5 by a rotating shaft, The top of the positioning frame 1 is fixedly connected with a bidirectional motor 7 by bolts, one end of the bidirectional motor 7 is provided with a fixing piece, the brake piece includes a unidirectional motor 12, a first gear 13, a second gear 14 and a synchronous toothed belt 15, the bottom of the inner cavity of the control box 2 is fixedly connected with the unidirectional motor 12 by bolts, the unidirectional motor 12 is fixedly connected with the first gear 13 by an output shaft, the first gear 13 is meshedly connected with the second gear 14 by a synchronous toothed belt 15, and the first gear 13 and the second gear 14 are fixedly connected with one end of the bidirectional threaded rod 3 passing through the positioning frame 1 on the side away from the unidirectional motor 12 by bolts;

[0020] By adopting the above technical scheme, the positioning frame 1 can be conveniently installed and fixed on the relevant printing equipment for use through its positioning frame 1, and the output of the one-way motor 12 fixedly connected to the bottom of the inner cavity of the control box 2 can drive the first gear 13 and the second gear 14 meshing with the synchronous belt 15 to rotate synchronously, thereby driving the two groups of bidirectional threaded rods 3 rotatably connected to the side wall of the inner cavity of the positioning frame 1 to rotate. Because the surfaces of the two groups of bidirectional threaded rods 3 are provided with two groups of opposite threaded patterns, the two groups of support frames 4 can be driven to move inward or outward synchronously to adjust the distance between them, and the paper can be limited in the conveying process through the multiple groups of rotating wheels 5 at the bottom of the support frame 4 to prevent it from offset, etc.

[0021] Reference Figure 1 and Figure 2The fixing parts include a limit plate 6, a push-pull rod 8, a sliding frame 9, a fixed frame 10 and a sliding block 11. The bidirectional motor 7 is fixedly connected with two sets of limit plates 6 through an output shaft. The two sets of limit plates 6 are rotatably connected with the push-pull rod 8 on the sides away from each other through a rotating shaft. The ends of the two sets of push-pull rods 8 away from the limit plates 6 are rotatably connected with the sliding block 11 through a rotating shaft. The surface of the sliding block 11 is slidably connected with the sliding frame 9. The top of the sliding frame 9 is fixedly connected to the top of the inner cavity of the positioning frame 1 by bolts, and the bottom of the sliding block 11 is fixedly connected with the two sets of fixed frames 10 by bolts;

[0022] By adopting the above technical solution, the output of the bidirectional motor 7 fixedly connected to the top of the positioning frame 1 can drive the two sets of limit plates 6 to rotate at the same time, and can synchronously drive the two sets of push-pull rods 8 to move. Under the limiting action of its sliding frame 9, the push-pull rod 8 can drive the sliding block 11 rotatably connected at one end to reciprocate up and down in its sliding frame 9, thereby driving the two sets of fixed frames 10 to move up and down, so that the paper can be pressed and fixed each time it is cut.

[0023] The implementation principle of a printing paper positioning structure in the embodiment of the present application is as follows: through its positioning frame 1, it is convenient to install and fix it as a whole on the relevant printing equipment for use, and through the output of the one-way motor 12 fixedly connected to the bottom of the inner cavity of the control box 2, it can drive the first gear 13 and the second gear 14 meshing with the synchronous toothed belt 15 to rotate synchronously, thereby driving the two groups of bidirectional threaded rods 3 rotatably connected to the inner cavity side wall of the positioning frame 1 to rotate. Because the surfaces of the two groups of bidirectional threaded rods 3 are provided with two groups of opposite threaded patterns, the two groups of support frames 4 can be driven to move inward or outward synchronously to adjust the distance between them, and the paper can be limited in the conveying process through the multiple groups of rotating wheels 5 at the bottom of the support frame 4 to prevent it from deflecting, etc., and the bidirectional threaded rods fixedly connected to the top of the positioning frame 1 can be used. The motor 7 outputs and can drive the two sets of limit plates 6 to rotate at the same time, and can synchronously drive the two sets of push-pull rods 8 to move. Under the limiting action of the sliding frame 9, the push-pull rod 8 can drive the sliding block 11 rotatably connected at one end to perform up and down reciprocating motion in the sliding frame 9, thereby driving the two sets of fixed frames 10 to move up and down, so that each time the paper is cut, the paper can be pressed and fixed, and the paper of different widths and according to different printing requirements can be limited, which can effectively prevent the deviation during the transportation process, and accordingly can effectively improve the actual printing and cutting accuracy, and each time the paper is cut, the paper can be pressed and fixed, which reduces the difficulty of operation and can also further improve the cutting quality of the paper.
