Description

Technical Field

[0001] This utility model relates to the field of paperboard conveying technology, and in particular to an anti-deviation structure for automated paperboard printing conveying. Background Technology

[0002] Paperboard printing is a process and technology for printing graphics on various paperboard materials. During the automated printing and conveying of paperboard, the paperboard may slide, deviate from the predetermined path, or rotate.

[0003] Due to the varying widths of different cardboard types, traditional cardboard anti-deviation structures are ill-suited to accommodate cardboard of various sizes. This results in some cardboard pieces not being effectively secured during transport, leading to cardboard deviation during conveying. This increases equipment downtime, forcing production interruptions and impacting overall efficiency during subsequent cardboard conveying. Furthermore, during conveying, some cardboard pieces may exhibit varying degrees of angular deviation on the conveyor belt surface, affecting the quality of the final printed product. This results in uneven or deviated printing effects, reduces equipment stability during operation, increases the risk of equipment failure, and ultimately lowers production efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to solve the problem of angular deviation of cardboard during conveying in the prior art, and to propose an anti-deviation structure for automated conveying of cardboard printing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An anti-deviation structure for automated conveying of cardboard printing includes a worktable and a fixed box. The fixed box is installed at the bottom of the worktable. A rotating shaft is symmetrically arranged inside the worktable. A conveyor belt is sleeved on the outer wall of the rotating shaft. The end of the conveyor belt has ventilation holes. Multiple guide wheels are symmetrically arranged inside the worktable to block the cardboard. A support plate is provided at the end of the worktable. A servo motor is provided on the side wall of the support plate. A transmission component is provided at the output end of the servo motor. Multiple suction cups are provided inside the fixed box to fix the cardboard. Multiple support legs are provided at the bottom of the worktable.

[0006] Preferably, the outer side wall of the rotating shaft is symmetrically provided with limiting rings, the side wall of the worktable is provided with a drive motor, and the output end of the drive motor is coaxially connected to the end of the rotating shaft.

[0007] Preferably, the transmission assembly includes a bidirectional lead screw and multiple moving blocks. A groove is provided in the support plate, the bidirectional lead screw is disposed on the inner sidewall of the groove, and the output end of the servo motor is coaxially connected to the end of the bidirectional lead screw. The multiple moving blocks are symmetrically disposed on the outer sidewall of the bidirectional lead screw.

[0008] Preferably, a limiting block is coaxially provided on the outer wall of the bidirectional lead screw, multiple sliding holes are provided at the end of the worktable, a connecting rod is provided at the end of the moving block and the connecting rod extends into the worktable, a moving plate is provided at the end of the connecting rod, and the end of the moving plate is connected to the ends of multiple retaining wheels.

[0009] Preferably, the fixed box has a rectangular hole at its end, the fixed box is connected to the workbench, the outer wall of the fixed box is equipped with an air pump, and the air pump is connected to multiple suction cups.

[0010] Preferably, the inner wall of the fixed box is provided with multiple guide plates, and the bottoms of the multiple suction cups are connected to the inner wall of the fixed box.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model, by setting up a transmission component, uses the output end of a servo motor to drive a bidirectional lead screw to rotate. The moving blocks on both sides move in opposite directions on the bidirectional lead screw through threaded holes. The moving blocks drive the moving plates to move in opposite directions through connecting rods, so that the moving plates drive multiple baffles to move, ensuring that the guide wheels can closely fit the two sides of the cardboard, thus ensuring the stability of the cardboard during conveying and reducing the occurrence of cardboard deviation.

[0012] 2. This utility model uses multiple suction cups.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-4 An anti-deviation structure for automated paperboard printing conveying includes a worktable 1 and a fixed box 13. The fixed box 13 is fixedly installed at the bottom of the worktable 1. Multiple support legs 12 are fixedly installed at the bottom of the worktable 1. A rotating shaft 7 is symmetrically rotated on the inner side wall of the worktable 1. A conveyor belt 10 is sleeved on the outer side wall of the rotating shaft 7. A ventilation hole 9 is opened at the end of the conveyor belt 10. A limiting ring 8 is symmetrically fixed on the outer side wall of the rotating shaft 7. A drive motor 11 is fixedly installed on the side wall of the worktable 1. The output end of the drive motor 11 is coaxially fixedly connected to the end of the rotating shaft 7. Through the cooperation of the limiting ring 8 and the ventilation hole 9, when the rotating shaft 7 drives the conveyor belt 10, it is prevented from accidentally falling off, which would affect the working efficiency of subsequent paperboard conveying. The ventilation hole 9 facilitates the subsequent fixation and adsorption of the paperboard, ensuring the stability of the equipment during operation.

[0017] The workbench 1 is symmetrically equipped with multiple guide wheels 6 to block the cardboard. The support plate 4 is fixedly installed at the end of the workbench 1. The servo motor 14 is fixedly installed on the side wall of the support plate 4. A shock-absorbing pad is provided between the servo motor 14 and the workbench 1. The servo motor 14 is equipped with a servo controller. Through the operation program of the servo controller, the rotation direction and rotation angle of the output end of the servo motor 14 are adjusted to effectively control the direction of rotation and provide driving force for the bidirectional lead screw 16. This operation program is existing technology and will not be described in detail here.

[0018] The output end of the servo motor 14 is equipped with a transmission assembly, which includes a bidirectional lead screw 16 and multiple moving blocks 15. A groove is provided in the support plate 4, and the bidirectional lead screw 16 is rotatably mounted on the inner side wall of the groove. The output end of the servo motor 14 and the end of the bidirectional lead screw 16 are coaxially and fixedly connected. Multiple moving blocks 15 are symmetrically arranged on the outer side wall of the bidirectional lead screw 16. The moving blocks 15 are provided with threaded holes that are compatible with the bidirectional lead screw 16. Through the mutual cooperation between the moving blocks 15 and the bidirectional lead screw 16, the moving blocks 15 on both sides can move in opposite directions on the bidirectional lead screw 16 through the threaded holes. This allows the operator to adjust the distance of the multiple guide wheels 6, block cardboard of different sizes, reduce the overall downtime of the equipment, and improve the equipment adaptability.

[0019] like Figure 2 As shown, a limiting block 17 is coaxially provided on the outer wall of the bidirectional lead screw 16, and a movable hole is provided in the limiting block 17. Multiple sliding holes 2 are provided at the end of the worktable 1. The connecting rod 3 is fixedly provided at the end of the moving block 15, and the end of the connecting rod 3 extends into the worktable 1. The moving plate 5 is fixedly provided at the end of the connecting rod 3. The end of the moving plate 5 is fixedly connected to the ends of multiple retaining wheels 6. Through the mutual cooperation of the limiting block 17 and the moving plate 5, collisions are prevented when the moving blocks 15 on both sides move in opposite directions, which would cause malfunctions during equipment operation and affect the stability of subsequent equipment operation.

[0020] The fixed box 13 is equipped with multiple suction cups 19 for fixing the cardboard. The fixed box 13 has a through hole at its end, which connects the end of the fixed box 13 to the bottom of the workbench 1. The air pump 18 is fixedly installed on the outer wall of the fixed box 13 and is connected to the multiple suction cups 19. Through the cooperation of the air pump 18 and the multiple suction cups 19, the multiple suction cups 19 adsorb and fix the cardboard through the ventilation hole 9, so that the cardboard and the surface of the conveyor belt 10 are tightly attached, reducing the angular deviation of the cardboard and ensuring the stability of the cardboard during transportation.

[0021] Multiple guide plates 20 are fixedly installed on the inner side wall of the fixed box 13, and the bottom of multiple suction cups 19 is connected to the inner side wall of the fixed box 13. Through the cooperation of the guide plates 20 and the suction cups 19, the stability of the suction cups 19 when adsorbing the cardboard is ensured, and the cardboard is prevented from shifting or slipping during the conveying process due to external airflow interference. It can effectively guide the airflow and make the airflow around the suction cups 19 more uniform and stable.

[0022] The functional principle of this utility model can be explained through the following operation methods: The operator drives the servo motor 14, and the output of the servo motor 14 drives the bidirectional lead screw 16 to rotate. The moving block 15 moves on the outer wall of the bidirectional lead screw 16 through the threaded hole. The moving block 15 drives the connecting rod 3 to move. The connecting rod 3 slides in the sliding hole 2. The connecting rod 3 drives multiple guide wheels 6 to move through the moving plate 5, thereby improving the adaptability of the equipment and reducing downtime. The drive motor 11 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the conveyor belt 10 to rotate. The conveyor belt 10 conveys the cardboard. By starting the air pump 18, which is connected to multiple suction cups 19, the multiple suction cups 19 fix the cardboard through the guide plate 20. The multiple suction cups 19 make the cardboard stick tightly to the end of the conveyor belt 10 through the ventilation holes 9, reducing the occurrence of angular deviation of the cardboard.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
