Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and more specifically, to a guiding mechanism for printing printed matter. Background Technology

[0002] The guiding mechanism for printed materials is a core auxiliary system in printing equipment that controls the movement trajectory of the substrate and ensures printing accuracy. Its design and performance directly determine the accuracy of registration, surface quality, and production stability of the printed materials. From simple manual adjustment to intelligent automatic correction, a multi-dimensional and high-precision technical system has been formed. The guiding mechanism is installed at the entrance of the printing unit and usually consists of a bracket, a guiding medium, and a transmission component. When the substrate is transported here, the positioning plate blocks the front end of the substrate, and the paper pressure tongue presses down to fix the position, ensuring that the longitudinal transport direction of each sheet of paper is completely consistent, avoiding the offset of the printed content caused by the misalignment of the paper. Since the downward pressure during the guiding process directly affects the stability of the guide, it is necessary to perform a guiding downward pressure operation.

[0003] In related technologies, during the use of the guiding mechanism, multiple guide blocks with elastic thrust are generally set on the surface of the guide roller to contact the printed matter. The guide roller then presses down on the printed matter to guide it.

[0004] However, in the current use of the guiding mechanism, due to the gaps between multiple guide blocks and the different contact and force applied between each guide block and the printed material during operation, when the guide block rotates with the guide roller and comes into contact with the printed material, it is very easy for the guide block to apply an elastic thrust to the printed material, which can cause the material to deviate due to the thrust, or even damage the surface of the printed material, thus affecting the guiding and pressing effect and guiding effect of the guiding structure.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figures 1-4This utility model provides a technical solution: a guiding mechanism for printing, including a base frame 1 and a movable guiding mechanism. A conveyor belt 2 is installed inside the base frame 1, and a motor 3 is installed on the left side of the rear side of the base frame 1. It can form a regular downward guiding contact on the top of the conveyor belt 2, and form guiding and anti-deviation media on both sides of the top of the conveyor belt 2, so that the user can perform downward guiding and anti-deviation work on the external printed materials conveyed by the conveyor belt 2, and avoid the situation where the printed materials are deviated or even damaged due to uneven downward pressure when the conveyor belt 2 conveys external printed materials. Therefore, the guiding downward pressure effect and guiding effect of the base frame 1 are improved.

[0021] Reference Figures 1-4 In a preferred embodiment, the movable guiding mechanism includes a guide groove 4, which is formed on both sides of the top of the base frame 1. A guide roller 5 located on the top of the conveyor belt 2 is movably connected inside the guide groove 4. A guide frame 6 is fixedly connected to both sides of the top of the base frame 1 and communicates with the guide groove 4. Guide plates 7 are movably connected to both sides of the outer side of the guide roller 5. A guiding lifting mechanism is located on the outer side of the top of the guide frame 6. The guide frame 6, in conjunction with the communicating guide groove 4, performs downward guiding work on the guide roller 5, and causes the guide plates 7 to form guiding and anti-deviation contact on both sides of the guide roller 5, so that the guide roller 5, in conjunction with the guide plates 7, guides the conveyor belt 2. The conveyor belt 2 performs downward guidance and anti-deviation work on the printed materials being conveyed. The guide lifting mechanism includes a lifting groove 8, a lifting frame 9, and a lifting hole 10. The lifting groove 8 is opened on the outer side of the top of the guide frame 6. The lifting frame 9 is movably connected to the inside of the lifting groove 8. The lifting hole 10 is opened at the bottom of the inner side of the lifting frame 9. The outer side of the guide roller 5 is located inside the lifting hole 10. This allows for lifting and lowering connection between the guide roller 5 and the guide frame 6, and provides a medium for the user to lift and move the guide roller 5. This avoids the situation where the guide roller 5 is difficult to lift and move by hand, thus improving the ease of lifting and lowering operation of the guide roller 5.

[0022] Reference Figures 2-4 In a preferred embodiment, a push groove 11 located inside the lifting groove 8 is provided on the top of the inner wall of the guide frame 6. A spring 12 is provided inside the guide frame 6, with one end of the spring 12 connected to the inner wall of the push groove 11. The guide frame 6 can apply downward guiding pressure to the guide roller 5, avoiding insufficient downward pressure when the guide roller 5 is working, thus improving the guiding and pressing effect of the guide roller 5. A pressure seat 13 located on the top of the guide roller 5 is movably connected inside the guide frame 6. A pressure groove 14 is provided on the top of the pressure seat 13. The other end of the spring 12 is connected to the inner wall of the pressure groove 14, which can provide a medium for the spring 12 to apply downward pressure to the guide roller 5. Since the bottom of the pressure seat 13 is inlaid with rolling balls that contact the guide roller 5, it can be ensured that the spring 12 applies downward pressure to the guide roller 5 without affecting the smooth operation of the guide roller 5, thus improving the downward pressing effect of the spring 12.

[0023] Reference Figures 2-4 In a preferred embodiment, grooves 15 are provided on both sides of the inner wall of the guide frame 6. A slider 16 is movably connected inside the groove 15. The inner side of the slider 16 is fixedly connected to the outer side of the pressure seat 13. This allows for a sliding connection between the pressure seat 13 and the guide frame 6, preventing the pressure seat 13 from shifting position and detaching from the guide frame 6 during operation. This improves the working stability of the pressure seat 13. A positioning cylinder 17, which communicates with the lifting groove 8, is fixedly connected to the top of the outer side of the guide frame 6. A positioning frame 18 is movably connected inside the positioning cylinder 17. A positioning hole 19 is provided at the bottom of the outer side of the lifting frame 9, allowing for insertion and positioning between the lifting frame 9 and the guide frame 6 after the lifting frame 9 has moved upward. This prevents the lifting frame 9 from being difficult to position after it drives the guide roller 5 upward, thus improving the positioning convenience of the lifting frame 9.

[0024] Reference Figures 2-3 In a preferred embodiment, a translation frame 20 is sleeved and connected to the outside of the lifting frame 9. The bottom of the translation frame 20 is fixedly connected to the top of the guide plate 7, and the top of the translation frame 20 is threadedly connected to a stud 21 that contacts the lifting frame 9. This allows for translational connection between the guide plate 7 and the lifting frame 9, and for threaded tightening and fixing of the translated guide plate 7 and the lifting frame 9. This improves the ease of translational operation and positioning of the guide plate 7. A docking groove 22 is provided on the rear side of the lifting frame 9, and a docking post 23 is movably connected inside the docking groove 22. The rear side of the docking post 23 is fixedly connected to the front side of the lifting frame 9, allowing for docking connection between the lifting frames 9. This avoids difficulties in synchronizing the connection between the lifting frames 9 during use, thus improving the connection effect and operational synchronization between the lifting frames 9.

[0025] Specifically, the working process or working principle of this printing guide mechanism is as follows: During use, the handheld lifting frame 9 moves the guide roller 5 upward through the lifting hole 10. At this time, the positioning hole 19 moves with the lifting frame 9 and aligns with the positioning cylinder 17. Then, the handheld positioning frame 18 moves inward and inserts into the positioning hole 19, thus positioning the lifting frame 9 and guide frame 6 after the lifting motion, ensuring the position of the guide roller 5 after the upward movement. Simultaneously, the docking column 23 cooperates with the docking groove 22 to connect the lifting frames 9. During this process, the pressure seat 13, affected by the upward movement of the guide roller 5, applies a contraction force to the spring 12, causing the spring 12 to contract into the push groove 11 and pressure groove 14. Simultaneously, the slider 16 moves with the pressure seat 13 within the slide groove 15, performing a lifting and lowering connection between the pressure seat 13 and the guide frame 6 to prevent deviation. Subsequently, the external printed material is moved to the top of the conveyor belt 2 to prepare for subsequent conveying and guiding of the printed material. Then, according to the size of the printed material, the handheld positioning frame 18 moves inward and inserts into the positioning hole 19. The horizontal transfer frame 20 moves towards the printed material, adjusting the guide anti-deviation range inside the guide plate 7. At this time, the horizontal transfer frame 20 moves outside the lifting frame 9, performing a horizontal connection between the guide plate 7 and the lifting frame 9. After the guide plate 7 is adjusted horizontally, the hand-held stud 21 is rotated downwards and contacts the top of the lifting frame 9, so that the stud 21 cooperates with the horizontal transfer frame 20 to perform threaded tight fixing between the guide plate 7 and the lifting frame 9. When the printed material moves to the top of the conveyor belt 2 and the inside of the guide plate 7, the hand-held positioning frame 18 moves outwards to disengage from the positioning hole 19, and through the lifting frame 9 and the lifting hole 10, drives the guide roller 5 to move downwards and contact the printed material at the top of the conveyor belt 2. At this time, the guide plate 7 moves to the outside of the printed material. At the same time, the contracted spring 12 cooperates with the pressure seat 13 to apply downward elastic pressure to the guide roller 5. When the conveyor belt 2 transports the printed material, the guide roller 5 cooperates with the guide plate 7 to guide and press down on the printed material while simultaneously guiding and preventing deviation.

[0026] It should be noted that the base frame 1, conveyor belt 2 and motor 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
