Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 and Figure 2This utility model provides an embodiment of a multifunctional paper positioning mechanism for a printing press, comprising a support plate 1, an electric push rod 101 fixedly connected to the upper surface of the support plate 1, a drive slider 102 fixedly disposed at the output end of the electric push rod 101, a drive block 103 fixedly connected to the upper surface of the drive slider 102, a drive disk 104 slidably connected to the outer wall of the drive block 103, the outer wall of the drive disk 104 rotatably connected to the inner wall of the support plate 1, a limit slider 105 fixedly connected to the lower surface of the drive block 103, and a first... The slide rail 106 has its outer wall slidably connected to the inner wall of the drive slider 102. The lower surface of the first slide rail 106 is fixedly connected to the upper surface of the support plate 1. The upper surface of the support plate 1 is fixedly connected to the paper carrier 107.

The limiting rod 109 has a moving component on its exterior.

[0025] Specifically, the electric push rod 101 is activated to push the drive slider 102 to slide, causing the drive block 103 to drive the drive disk 104 to rotate. Due to the rotation of the drive disk 104, the limiting slider 105 slides on the outer wall of the first slide rail 106. The limiting plate 108 to be used is placed on the upper surface of the paper carrier 107 through the limiting rod 109. Under the action of the limiting slider 105 and the paper carrier 107, the paper is aligned. This component can not only achieve the effect of aligning the paper, but also achieve the effect of being suitable for different paper sizes.

[0026] Reference Figure 1 and Figure 3 The moving component includes a suction cup 2, the interior of which is located outside the limiting rod 109. A paper feeding slider 201 is fixedly connected to the upper surface of the suction cup 2, and a second slider 202 is slidably connected to the inner wall of the paper feeding slider 201. A support bracket 203 is fixedly connected to the upper surface of the second slider 202, and the upper surface of the paper feeding slider 201 is slidably connected to the inner top wall of the support bracket 203. A lifting component is provided on the inner wall of the support bracket 203.

[0027] Specifically, by activating the suction cup 2 and the paper feeding slider 201 sliding on the outer wall of the second slider 202, the paper is fed onto the conveyor belt of the printing press, and the support bracket 203 is used to provide a carrier for the whole.

[0028] Reference Figure 1 and Figure 4The lifting assembly includes a base plate 3, the lower surface of which is fixedly connected to the inner wall of the support bracket 203. A fixing block 301 is fixedly connected to the upper surface of the base plate 3, and a hydraulic rod 302 is fixedly connected to the upper surface of the fixing block 301. A rack 303 is fixedly installed at the output end of the hydraulic rod 302. A gear 304 is meshed with the tooth end of the rack 303. A rotating shaft 305 is fixedly connected to the inner wall of the gear 304, and a support block 306 is rotatably connected to the outer wall of the rotating shaft 305. The lower surface of the support block 306... The rotating shaft 305 is fixedly connected to the upper surface of the base plate 3; an extension bracket 307 is fixedly connected to the outer wall of the rotating shaft 305, and a moving block 308 is rotatably connected to the inner wall of the extension bracket 307; a sliding block 309 is fixedly connected to the upper surface of the moving block 308, and a support plate 310 is fixedly connected to the upper surface of the sliding block 309, and the upper surface of the support plate 310 is fixedly connected to the lower surface of the bearing plate 1; a limit post 311 is slidably connected to the inner wall of the sliding block 309, and the lower surface of the limit post 311 is fixedly connected to the lower surface of the base plate 3;

[0029] Specifically, the hydraulic rod 302 fixed on the fixed block 301 is activated to push the rack 303 to move, causing the gear 304 to rotate. The gear 304 drives the rotating shaft 305 to rotate on the inner wall of the bearing block 306, causing the extension bracket 307 to extend. The extension bracket 307 drives the moving block 308 to move, causing the sliding block 309 to slide on the outer wall of the limiting post 311 fixed on the base plate 3. This component can facilitate the feeding of paper into the printing press and improve printing efficiency.

[0030] Working principle: When this mechanism is needed, firstly, the limiting plate 108 corresponding to the paper size is passed through the limiting rod 109 and placed on the upper surface of the paper carrier 107. Then, the electric push rod 101 fixed on the carrier plate 1 is activated. The electric push rod 101 pushes the drive slider 102 to slide on the outer wall of the first slide rail 106. The movement of the drive slider 102 drives the drive block 103, which in turn causes the drive disk 104 to rotate. When the drive disk 104 rotates, it drives the drive block 103 fixed on the limiting slider 105, causing the limiting slider 105 to slide on the outer wall of the first slide rail 106, thereby achieving paper alignment. It is worth mentioning that the telescopic rods on the limiting slider 105 and the limiting rod 109 can be adjusted according to the number of papers. This component can not only align papers, but is also suitable for papers of different sizes. After the paper alignment is completed, the paper feeding slider 201... The outer wall of the two sliders 202 slides, and the paper is fed onto the conveyor belt of the printing press via the suction cup 2. The support bracket 203 provided here provides a stable carrier for the entire paper feeding process. In addition, the hydraulic rod 302 fixed on the fixed block 301 is activated, which pushes the rack 303 to move, thereby causing the gear 304 to rotate. The rotation of the gear 304 drives the rotating shaft 305 to rotate on the inner wall of the support block 306, thereby extending the extension bracket 307. The extension of the extension bracket 307 drives the moving block 308 to move, causing the sliding block 309 to slide on the outer wall of the upper limit post 311 of the base plate 3, and finally realizing the movement of the tray 310. This component can effectively facilitate the feeding of paper into the printing press and improve printing efficiency. In summary, this mechanism realizes the functions of paper alignment and adaptation to different paper sizes on the one hand, and achieves the effect of facilitating the feeding of paper into the printing press and improving printing efficiency on the other hand.
