At present, in the production process of books and periodicals, they are cut to ensure the consistency of the size of the pages. When traditional book and periodical cutting equipment is cutting, it is easy to deviate due to the inconsistency of the size and thickness of the books and periodicals, resulting in uneven cut books and periodicals. At present, books are usually corrected by manual calibration, but the manual correction speed is slow, resulting in low processing efficiency; and simple book and periodical positioning fixtures have low correction accuracy, which easily leads to waste of book and periodical cutting.

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

[0019] The present application embodiment discloses a book cutting and correction mechanism. Figure 1 , including a support plate 1, a connecting frame 2 is welded at the center of the outer walls on both sides of the support plate 1, and a fixing plate 3 is welded on the top of the connecting frame 2 in an integrated structure. The installation of the support plate 1 can be completed by fixing the fixing plate 3, a mounting frame 13 is welded at the center of the back wall of the support plate 1, and an electric push rod 2 14 is installed at the center of the inner wall of the mounting frame 13. The output end of the electric push rod 2 14 is fixedly connected with a push plate 21, and the push plate 21 can be pushed by the electric push rod 2 14 to make a linear reciprocating motion so that the books and periodicals can be pushed outward. Correcting frames 4 are provided on both sides of the top of the support plate 1, and a rotating shaft 11 is rotatably installed on the top of the two correcting frames 4, and a connecting rod 10 is fixed on the outer wall of the rotating shaft 11. A connecting shaft 12 is fixed at the center of the top of the support plate 1, and a rotating cross bar 9 is rotatably connected to the top of the connecting shaft 12, and the rotating cross bar 9 is located between the two correcting frames 4.

[0020] like Figure 2 As shown, the ends of the two connecting rods 10 that are close to each other are rotatably connected to both sides of the top of the rotating cross bar 9, and an electric push rod 8 is fixedly installed on one side of the top of the support plate 1. The output end of the electric push rod 8 is rotatably connected to the outer wall of one of the correcting frames 4. Therefore, when the electric push rod 8 is working, it can push one of the correcting frames 4 away to one side, and then pull the rotating cross bar 9 to rotate synchronously. As the rotating cross bar 9 rotates, its other end will push the other correcting frame 4 away to one side, so that the two correcting frames 4 can approach or move away synchronously, and slide rails 15 are symmetrically fixed on the top of the support plate 1. The bottom of the two correcting frames 4 are connected to sliders 16 adapted to the slide rails 15 by screws, which can cooperate to support the bottom of the correcting frames 4.

[0021] A protective cover 5 is fixed to the front end of the top of the support plate 1, and a double-headed motor 6 is installed at the center of the inside of the protective cover 5. Screw rods 7 are transmission-connected to both sides of the double-headed motor 6, and sliding blocks are slidably connected to the outsides of the two screw rods 7. The double-headed motor 6 can drive the screw rods 7 on both sides to rotate synchronously, thereby driving the sliding block to move in a straight line. Since a bracket is fixed to the outer wall of the sliding block, a smoothing roller 22 is rotatably installed on the bottom end of the bracket. As the sliding block moves in a straight line, the smoothing roller 22 can be pushed to move, thereby smoothing the surface of the books and periodicals.

[0022] like Figure 3As shown, a correction part is provided at the corners of the bottom of the support plate 1, and the correction part includes a rotating shaft 17, connecting rods 18 fixed on both sides of the rotating shaft 17, and a correction wheel 19 arranged on the connecting rod 18. The rotating shaft 17 is rotatably connected to the corners of the bottom of the support plate 1, and the correction wheel 19 is rotatably connected to the connecting rod 18. A limit lever 20 for limiting the connecting rod 18 is fixed on the inner side of the rotating shaft 17, and the limit lever 20 is located between the two connecting rods 18 to assist the correction wheel 19 in positioning the corners of books and periodicals.

[0023] The implementation principle of a book and periodical cutting and correcting mechanism in the embodiment of the present application is as follows: the fixing plate 3 is pre-installed at the feed port of the cutting machine so as to be connected to the output end of the driving mechanism. With the operation of the driving mechanism, the supporting plate 1 can be pushed downward to approach the surface of the book and periodical. Then, the electric push rod 18 is started to work to push one of the correcting frames 4 to one side. With the movement of the correcting frame 4, the connecting rod 10 will cooperate with the rotating shaft 11 to rotate and pull the rotating cross bar 9 to rotate outside the connecting shaft 12. With the rotation of the rotating cross bar 9, the other end thereof will push the other correcting frame 4 to move to the other side. Thus, with the extension and retraction of the electric push rod 18, the two correcting frames 4 can be driven to approach or move away from each other. When the two correcting frames 4 move, the slider 16 will cooperate with the sliding support outside the slide rail 15 to improve stability and facilitate adjustment of the appropriate correcting distance according to the size of the book and periodical.

[0024] As the two deflection correcting frames 4 approach, the deflection correcting wheels 19 approach the corners of the books and periodicals, rub against the books and periodicals, and cooperate with the rotation outside the rotating shaft 17 to adjust the appropriate angle, thereby facilitating the straightening of the corners of the books and periodicals. At the same time, the limit lever 20 can limit the position between the two deflection correcting wheels 19 to prevent excessive angle deviation. When the books and periodicals are straightened, the double-headed motor 6 inside the protective cover 5 is started to drive the two screws 7 to rotate, and then the two smoothing rollers 22 can be pushed to roll to both sides by the sliding block to smooth the surface of the books and periodicals, assisting in positioning and cutting. After cutting, the electric push rod 2 14 works to push the push plate 21 to one side, so that the cut books and periodicals can be pushed out.
