Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper alignment technology, specifically a paper conveyor for paper alignment. Background Technology
[0002] In the continuous paper conveying process of a paper conveying system, a high-precision correction device must be equipped to monitor and dynamically correct the paper's trajectory in real time. Its core function is to actively eliminate any lateral deviation or angular skew that may occur during the paper's movement, ensuring that each sheet of paper can enter the subsequent operation with a precise posture and position.
[0003] For example, the patent with authorization announcement number CN223015988U describes a paper correction structure for a printing press, which includes two rotating shafts. The two rotating shafts rotate synchronously, driving the threaded plates on the surface of the rotating shafts to move, and the threaded plates correct the paper.
[0004] The existing technology has the following problems:
[0005] In existing technologies, paper is corrected by using threaded plates. However, this method is only applicable to paper with regular shapes. When dealing with irregularly shaped paper, the friction generated by the contact between the two sides of the paper and the threaded plates is significantly different, resulting in an imbalance of the correction force and making it impossible to achieve effective correction. Therefore, its applicability is limited.
[0006] Based on this, a paper conveyor for paper correction is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
[0007] The purpose of this invention is to provide a paper conveyor for paper deviation correction, so as to solve the problems in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A paper conveyor for paper correction includes a conveyor frame, a correction frame in the middle of the conveyor frame, two rotating rollers rotatably mounted in the middle of the correction frame, a plurality of limiting grooves evenly provided on the rotating rollers, a plurality of conveyor belts provided in the limiting grooves, a correction device on the correction frame, the correction device including fixed rods, two fixed rods mounted in the middle of the correction frame, sliding seats slidably mounted on the fixed rods, a slide rail fixedly connected to the inner wall of the correction frame, a slider slidably mounted in the slide rail, the slider being connected to a connecting frame, the connecting frame being connected to a stop block by screws, and the stop block having a guide groove adapted to the paper.
[0010] Based on the above technical solutions, this utility model also provides the following optional technical solutions:
[0011] In one alternative: a pulley is fixedly connected to the side of the rotating roller, and the two pulleys are driven by a belt. The output end of a first rotating motor is fixedly connected to the side of the pulley, and the first rotating motor is mounted on the surface of the error correction frame.
[0012] In one alternative: the surface of the fixing rod is uniformly provided with a plurality of limiting holes, the sliding seat is threadedly connected to the fixing bolt, and the fixing bolt passes through the limiting holes for limitation.
[0013] In one alternative: the sliding seat is fixedly connected to a limiting block or a fixing block, the fixing block is equipped with a telescopic rod, and the output end of the telescopic rod is fixedly connected to a lower pressure plate.
[0014] In one alternative: the slider is rotatably connected to one end of the transmission arm, the other end of the transmission arm is rotatably connected to the rotating disk, the rotating disk is fixedly connected to the first rotating shaft, the first rotating shaft is rotatably connected to the error correction frame, the surface of the telescopic rod is fixedly connected to the first limiting block, the first limiting block is connected to the gear, and the first limiting block and the gear are coaxial.
[0015] In one alternative: a second rotating shaft is provided on the side of the first rotating shaft, the second rotating shaft is rotatably connected to the error correction frame, the second rotating shaft is fixedly connected to the output end of the second rotating motor, and the fixed end of the second rotating motor is connected to the surface of the error correction frame.
[0016] In one alternative: a second limiting block is fixedly connected to the surface of the second rotating shaft, the second limiting block is connected to the half gear, the second limiting block and the half gear are coaxial, the first limiting block is provided with a slot that matches the second limiting block, and the half gear meshes with the gear for transmission.
[0017] In one alternative: the surface of the lower pressure plate is provided with a cushioning pad.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. This utility model uses two limiting blocks to correct the deviation of the paper on both sides, while the lower pressure plate restricts the position of the paper to prevent misalignment. When the paper is powered by the conveyor belt to move to the stop position, the stop block hinders its forward movement, making the paper fit tightly against the surface of the stop block. At the same time, the side of the paper is embedded in the guide groove of the stop block to complete the deviation correction. After the deviation correction, the stop block is raised so that it does not interfere with the movement of the paper. After a single sheet of paper is conveyed, the stop block is lowered again to return to its position to prepare for the next deviation correction. The limiting blocks and the stop blocks work together to achieve deviation correction from multiple angles. Moreover, by replacing the stop blocks, it can be adapted to paper sheets of different shapes, not limited to regular shapes, thus increasing practicality.
[0020] 2. This utility model drives the second limiting block and the half gear to rotate via the second rotating shaft. When the half gear meshes with the gear, it drives the gear to rotate through meshing transmission, thereby moving the first limiting block, the first transmission shaft, the rotating disk, and the transmission arm. This causes the slider to slide within the slide rail, ultimately driving the connecting frame and the stop block to move. When the half gear disengages from the gear, the second limiting block constrains the rotation of the first limiting block, and the first limiting block locks the first transmission shaft, thereby fixing the rotating disk, the transmission arm, and the slider. This restricts the movement of the connecting frame and the stop block, providing the necessary time for correction. When the half gear meshes with the gear again, the stop block moves upward, outputting the paper sheet that has completed correction, thus realizing the transportation and correction of the paper. By adjusting the rotation speed of the second rotating shaft, it can be adapted to production lines with different speeds, facilitating the adjustment of the equipment's operating speed.

[0031] In one embodiment, such as Figures 1-3 As shown, a paper conveyor for paper correction includes a conveyor frame 101, a correction frame 201 in the middle of the conveyor frame 101, two rotating rollers 301 rotatably mounted in the middle of the correction frame 201, a plurality of limiting grooves 302 evenly provided on the rotating rollers 301, a plurality of conveyor belts 303 provided in the limiting grooves 302, a correction device on the correction frame 201, the correction device including a fixing rod 401, two fixing rods 401 mounted in the middle of the correction frame 201, a sliding seat 402 slidably mounted on the fixing rods 401, a slide rail 502 fixedly connected to the inner wall of the correction frame 201, a slider 503 slidably mounted in the slide rail 502, the slider 503 connected to a connecting frame 504, and the connecting frame 504 connected to a stop block 501 by screws. The connection is as follows: the stop block 501 is provided with a guide groove adapted to the paper. The paper is conveyed by the conveyor frame 101. The paper moves to the position of the rotating roller 301. The limiting groove 302 provides the installation conditions for the conveyor belt 303. The rotating roller 301 rotates to drive the conveyor belt 303 to move. The conveyor belt 303 drives the paper to move. The two fixed rods 401 provide the adjustment conditions for the sliding seat 402. The slide rail 502 provides the sliding conditions for the slider 503. The slider 503 drives the connecting frame 504 to move. The connecting frame 504 drives the stop block 501 to move. The stop block 501 limits the paper. The paper moves into the guide groove on the stop block 501 for correction. The stop block 501 is lifted and moves upward. The paper sheet after correction is output, and the correction operation is completed.
[0032] In one embodiment, such as Figure 3 and Figure 4 As shown, the rotating roller 301 is fixedly connected to the side of the pulley 304, and the two pulleys 304 are driven by a belt. The output end of the first rotating motor 305 is fixedly connected to the side of the pulley 304. The first rotating motor 305 is mounted on the surface of the error correction frame 201. The first rotating motor 305 drives the pulley 304 to rotate, and the belt drives the rotation, so that the two rotating rollers 301 rotate synchronously, providing power for the rotation of the rotating rollers 301.
[0033] In one embodiment, such as Figure 4 and Figure 5As shown, the surface of the fixing rod 401 is evenly provided with a plurality of limiting holes 403. The sliding seat 402 is threadedly connected to the fixing bolt 404. The fixing bolt 404 passes through the limiting hole 403 for limiting. By screwing the fixing bolt 404 into the sliding seat 402, the fixing bolt 404 passes through the limiting hole 403, and the fixing bolt 404 passes through the limiting hole 403 to limit the sliding seat 402, providing conditions for the adjustment of the sliding seat 402.
[0034] In one embodiment, such as Figure 4 As shown, the sliding seat 402 is fixedly connected to the limiting block 405 or the fixing block 406. A telescopic rod 407 is installed on the fixing block 406. The output end of the telescopic rod 407 is fixedly connected to the lower pressure plate 408. The position of the limiting block 405 or the fixing block 406 can be adjusted by adjusting the position of the sliding seat 402. Adjusting the position of the two limiting blocks 405 provides conditions for guiding paper of different sizes, increasing the applicability of the equipment. The lower pressure plate 408 is moved by the telescopic rod 407 to adjust the position of the lower pressure plate 408. Adjusting the position of the lower pressure plate 408 changes the distance between the lower pressure plate 408 and the conveyor belt 303, which facilitates the conveying of paper of different thicknesses, avoids paper stacking, and conveys paper in sequence.
[0035] In one embodiment, such as Figure 5 and Figure 6 As shown, the slider 503 is rotatably connected to one end of the transmission arm 505, and the other end of the transmission arm 505 is rotatably connected to the rotating disk 506. The rotating disk 506 is fixedly connected to the first rotating shaft 507, and the first rotating shaft 507 is rotatably connected to the error correction frame 201. The surface of the telescopic rod 407 is fixedly connected to the first limiting block 508, which is connected to the gear 509. The first limiting block 508 and the gear 509 are coaxial. The gear 509 drives the first limiting block 508 and the first rotating shaft 507 to rotate, the first rotating shaft 507 drives the rotating disk 506 to rotate, the rotating disk 506 drives the transmission arm 505 to move, and the transmission arm 505 drives the slider 503 to slide in the slide rail 502. The slider 503 drives the connecting frame 504 and the stop block 501 to move, providing power for the movement of the stop block 501.
[0036] In one embodiment, such as Figure 6 and Figure 7 As shown, a second rotating shaft 510 is provided on the side of the first rotating shaft 507. The second rotating shaft 510 is rotatably connected to the error correction frame 201. The second rotating shaft 510 is fixedly connected to the output end of the second rotating motor 513. The fixed end of the second rotating motor 513 is connected to the surface of the error correction frame 201. The second rotating shaft 510 is driven to rotate by the second rotating motor 513, providing power for the movement of the second rotating shaft 510.
[0037] In one embodiment, such as Figure 7 and Figure 8 As shown, a second limiting block 511 is fixedly connected to the surface of the second rotating shaft 510. The second limiting block 511 is connected to a half gear 512. The second limiting block 511 and the half gear 512 are coaxial. The first limiting block 508 is provided with a slot that matches the second limiting block 511. The half gear 512 meshes with the gear 509 for transmission. The rotation of the second rotating shaft 510 drives the second limiting block 511 and the half gear 512 to rotate. When the half gear 512 meshes with the gear 509, the half gear 512 drives the gear 509 to rotate through the meshing transmission. When the half gear 512 does not mesh with the gear 509, the second limiting block 511 restricts the rotation of the first limiting block 508. The first limiting block 508 restricts the rotation of the first rotating shaft 507. The stop block 501 performs a correction operation. When the half gear 512 meshes with the gear 509 again, the stop block 501 moves upward to convey paper, providing conditions for the movement of the stop block 501.
[0038] The above embodiment discloses a paper conveyor for paper alignment. Paper is conveyed via a conveyor frame 101, moving to the position of the rotating roller 301. A limiting groove 302 provides installation conditions for the conveyor belt 303. A first rotating motor 305 drives the pulley 304 to rotate, and a belt drives the two rotating rollers 301 to rotate synchronously, providing power for their rotation. The rotation of the rotating rollers 301 drives the conveyor belt 303, which in turn moves the paper. A fixing bolt 404 is screwed into the sliding seat 402, passing through the limiting hole 4. 03. The sliding seat 402 is limited by the fixing bolt 404 passing through the limiting hole 403, providing conditions for the adjustment of the sliding seat 402. The two fixing rods 401 provide adjustment conditions for the sliding seat 402. The position of the limiting block 405 or the fixing block 406 is adjusted by adjusting the position of the sliding seat 402. Adjusting the position of the two limiting blocks 405 provides conditions for guiding paper of different sizes, increasing the applicability of the equipment. The lower pressure plate 408 is moved by the telescopic rod 407 to adjust the position of the lower pressure plate 408. Adjusting the position of the lower pressure plate 408 changes the distance between the lower pressure plate 408 and the conveyor belt 303. This design facilitates the conveying of papers of different thicknesses, preventing paper stacking and allowing for sequential paper feeding. The slide rail 502 provides sliding conditions for the slider 503. The second rotating shaft 510 rotates, driving the second limiting block 511 and the half-gear 512. When the half-gear 512 meshes with the gear 509, it drives the gear 509 to rotate. The gear 509 then drives the first limiting block 508 and the first rotating shaft 507 to rotate. The first rotating shaft 507 drives the rotating disk 506 to rotate, which in turn drives the transmission arm 505. 5. The slider 503 slides within the slide rail 502, which in turn drives the connecting frame 504 to move. The connecting frame 504 then drives the stop block 501 to move. When the half gear 512 is not engaged with the gear 509, the second limit block 511 restricts the rotation of the first limit block 508, which in turn restricts the rotation of the first rotating shaft 507. The stop block 501 limits the paper, which moves into the guide groove on the stop block 501 for correction. When the half gear 512 engages with the gear 509 again, the stop block 501 moves upward, outputting the corrected paper and completing the paper transport correction.
