Description

Technical Field

[0001] This utility model relates to the field of conveying technology, specifically a digital printed matter conveying device. Background Technology

[0002] In the digital printing process, printed materials need to go through multiple steps, such as printing, drying, cutting, and sorting. The conveying of printed materials is a key link connecting these steps, and existing conveying devices have some shortcomings.

[0003] According to the authorized patent "CN114392934A" for a digital printed matter conveying device, it includes a screening and conveying mechanism, a screening robotic arm, a printing mechanism, and a recycling bin. The screening and conveying mechanism includes a sloping feeding conveyor belt, a triangular conveyor frame, and a drive assembly. The feeding conveyor belt has multiple bases suitable for battery insertion. This invention achieves battery detection by configuring the feeding conveyor belt, bases, triangular conveyor frame, and drive assembly.

[0004] The aforementioned technical solutions rely heavily on mechanical contact positioning structures for the positioning of printed materials during transport. For example, common mechanical baffle positioning suffers from wear and tear due to friction between the baffle and the printed material after prolonged and frequent use, leading to a continuous decrease in positioning accuracy. This makes the printed material prone to positional deviations in subsequent processes, affecting registration accuracy and increasing the rate of rejects.

[0005] Therefore, this utility model provides a digital printing conveying device. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a digital printing material conveying device to solve the above problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a digital printing conveying device, including a worktable, a controller fixedly connected to the outside of the worktable, a conveying mechanism provided inside the worktable, and a positioning mechanism provided on the outside of the worktable;

[0008] The conveying mechanism includes a motor, and the output end of the motor is connected to a conveyor belt via a roller drive.

[0009] The positioning mechanism includes a belt, with a rotating rod connected to the inner side of one end of the belt. A rotating rod is fixedly connected to the outer side of the rotating rod. A first magnetic pole cover is fixedly connected to the outer side of the rotating rod. A sliding groove is fixedly connected to the top of the worktable. A slider is slidably engaged inside the sliding groove. A moving block is fixedly connected to the top of the slider. A return spring is fixedly connected to the outer side of the slider. A force-bearing rod is fixedly connected to the outer side of the moving block. A second magnetic pole cover is fixedly connected to the outer side of the force-bearing rod. A connecting rod is fixedly connected to the side of the moving block away from the force-bearing rod. A positioning plate is fixedly connected to the outer side of the connecting rod.

[0010] Preferably, a cleaning mechanism is provided on the outer side of the conveyor belt. The cleaning mechanism includes a squeezing rod. A connecting plate is fixedly connected to the top of the workbench. An elastic airbag is fixedly connected to the outer side of the connecting plate. An air guide pipe is fixedly connected to the outer side of the elastic airbag. An air jet plate is fixedly connected to the outer side of the air guide pipe.

[0011] Preferably, the conveyor belt is rotatably connected to the inside of the workbench via a motor, and the end of the belt away from the rotating rod is drive-connected to the outside of the motor's output end.

[0012] Preferably, the rotating rod is rotatably connected to the outside of the worktable, and the rotating rod and the first magnetic pole cover are evenly distributed on the outside of the rotating rod.

[0016] Beneficial effects

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] (1) The positioning mechanism of this digital printing conveyor is ingeniously designed. The motor output simultaneously drives the belt, which in turn causes the rotating rod to rotate. The rotating rod fixed on the rotating rod and the first magnetic pole cover rotate accordingly. When the first magnetic pole cover approaches the second magnetic pole cover (both are magnetic poles of the same name), the repulsive force pushes the moving block to slide in the sliding groove through the slider, compressing the reset spring. The moving block drives the connecting rod and the positioning plate to move towards the conveyor belt, thereby achieving precise positioning of the printed matter.

[0019] (2) In this digital printing conveyor, the cleaning mechanism uses the movement of the moving block in the positioning mechanism to achieve automatic cleaning. The squeezing rod is fixed on the outside of the moving block. As the moving block moves, it squeezes the elastic airbag. The gas in the elastic airbag enters the jet plate through the air guide pipe and is sprayed out from the dense holes on the inner wall of the jet plate to clean the conveyor belt.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 A digital printing conveying device includes a worktable 1, a controller 2 fixedly connected to the outside of the worktable 1, a conveying mechanism 3 inside the worktable 1, and a positioning mechanism 4 outside the worktable 1.

[0027] The conveying mechanism 3 includes a motor 31, and the output end of the motor 31 is connected to a conveyor belt 32 via a roller drive.

[0028] The positioning mechanism 4 includes a belt 41, with a rotating rod 42 connected to the inner side of one end of the belt 41. A rotating rod 43 is fixedly connected to the outer side of the rotating rod 42. A first magnetic pole cover 44 is fixedly connected to the outer side of the rotating rod 43. A sliding groove 45 is fixedly connected to the top of the worktable 1. A slider 46 is slidably engaged inside the sliding groove 45. A moving block 47 is fixedly connected to the top of the slider 46. A return spring 48 is fixedly connected to the outer side of the slider 46. A force-bearing rod 49 is fixedly connected to the outer side of the moving block 47. A second magnetic pole cover 410 is fixedly connected to the outer side of the force-bearing rod 49. A connecting rod 411 is fixedly connected to the side of the moving block 47 away from the force-bearing rod 49. A positioning plate 412 is fixedly connected to the outer side of the connecting rod 411.

[0029] Furthermore: the conveyor belt 32 is rotatably connected to the inside of the workbench 1 via the motor 31, the end of the belt 41 away from the rotating rod 42 is connected to the outside of the output end of the motor 31, the rotating rod 42 is rotatably connected to the outside of the workbench 1, the rotating rod 43 and the first magnetic pole cover 44 are evenly distributed on the outside of the rotating rod 42, the moving block 47 is slidably connected to the top of the sliding groove 45 via the slider 46 and the return spring 48, the first magnetic pole cover 44 is movably connected to the outside of the second magnetic pole cover 410, and the two are magnetic poles of the same name, and the positioning plate 412 is movably and symmetrically distributed above the conveyor belt 32.

[0030] It should be noted that the connection between the controller 2 and the motor 31 lays the foundation for precise control of the entire conveying process. By presetting different parameters through the controller 2, the motor 31 can flexibly adjust its output speed according to the actual needs of the printing process.

[0031] Specifically, the positioning plate 412 is driven to move by the principle of mutual repulsion between like magnetic poles. Compared with the traditional mechanical contact positioning method, this non-contact positioning method avoids the problem of reduced positioning accuracy caused by mechanical wear, and greatly improves the service life and stability of the positioning mechanism 4. In addition, the magnitude of the repulsive force between the magnetic poles is closely related to the distance between them. By reasonably designing the size, shape and magnetic field strength of the first magnetic pole cover 44 and the second magnetic pole cover 410, the moving distance and speed of the positioning plate 412 can be precisely controlled to adapt to the positioning needs of printed materials of different sizes and weights.

[0032] As a further improvement of this utility model, a cleaning mechanism 5 is provided on the outer side of the conveyor belt 32. The cleaning mechanism 5 includes a squeezing rod 51. A connecting plate 52 is fixedly connected to the top of the workbench 1. An elastic airbag 53 is fixedly connected to the outer side of the connecting plate 52. An air guide pipe 54 is fixedly connected to the outer side of the elastic airbag 53. An air jet plate 55 is fixedly connected to the outer side of the air guide pipe 54.

[0033] It should be noted that: the extrusion rod 51 is fixedly connected to the outside of the moving block 47, and the extrusion rod 51 is located outside the elastic airbag 53. The jet plate 55 is fixedly connected to the top of the conveyor belt 32 through the air guide pipe 54, and the inner wall of the jet plate 55 is provided with densely packed small holes.

[0034] Furthermore, the structural design of the elastic airbag 53, air duct 54, and jet plate 55 makes the maintenance and cleaning of the cleaning mechanism 5 very convenient. The elastic airbag 53 adopts a replaceable design, and can be quickly replaced when its elasticity decreases or it is damaged. Although the small holes on the inner wall of the jet plate 55 are dense, its simple structure allows for easy maintenance through simple disassembly and cleaning when blockage occurs. In addition, the entire cleaning mechanism 5 has a small number of parts and a simple and clear connection method, which reduces the difficulty and complexity of maintenance.

[0035] Specifically: The elastic airbag 53 is made of highly elastic silicone material, with an internal volume of 50-100mL and a compression stroke of 30-50mm. When the moving block 47 drives the squeezing rod 51 to fully compress the airbag, the volume compression ratio can reach 2:1, generating an airflow pressure of approximately 0.15-0.2MPa. According to Bernoulli's equation, the airflow velocity through the small holes (0.5-1mm in diameter) on the inner wall of the jet plate 55 can reach 20-30m / s, sufficient to blow away paper fibers and toner particles (density approximately 0.3-0.5g / cm³). 3 Small and light items;

[0036] The jet plate 55 employs a multi-hole array design with a hole density of 50-100 holes / cm². 2 Furthermore, the orifice is conical (large inlet, small outlet), utilizing the Venturi effect to further increase the airflow velocity. At the same time, the jet plate is installed at an angle (30-45° with the conveyor belt), so that the airflow forms a lateral sweeping force rather than a vertical impact, avoiding vertical splashing and falling of debris.

[0037] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0038] Working principle: When the device is started, the controller 2 sends a running command to the motor 31, and the motor 31 starts to work. Its output end rotates at high speed. Through the transmission connection with the roller, it drives the roller to rotate synchronously. Since the conveyor belt 32 is wrapped on the roller, under the action of the friction of the roller, the conveyor belt 32 starts to rotate in a cycle, thereby conveying the printed materials placed on it along the preset direction of the worktable 1, realizing the efficient transfer of printed materials between different printing processes.

[0039] While the motor 31 drives the conveyor belt 32, the belt 41 on the outer side of its output end is also driven to rotate. The inner side of the other end of the belt 41 is connected to the rotating rod 42, causing the rotating rod 42 to rotate around its axis. The rotating rods 43, which are evenly distributed on the outer side of the rotating rod 42, and the first magnetic pole cover 44 rotate synchronously. When the first magnetic pole cover 44 rotates with the rotating rod 42 and approaches the second magnetic pole cover 410, because the two are magnetic poles of the same name, according to the principle that like poles repel each other, the first magnetic pole cover 410... The magnetic pole cover 44 generates a repulsive force on the second magnetic pole cover 410, which is fixed to the force-bearing rod 49. The force-bearing rod 49 is connected to the moving block 47. Therefore, the repulsive force pushes the moving block 47 to slide in the sliding groove 45 via the slider 46 towards the conveyor belt 32, while simultaneously compressing the return spring 48. During the sliding process, the moving block 47 drives the connecting rod 411 and the positioning plate 412 connected to its outer side to move together, and the positioning plate 412 gradually approaches the printed matter on the conveyor belt 32. When the first magnetic pole cover 44 continues to rotate away from the second magnetic pole cover 410 with the rotating rod 42, the return spring 48 returns to its original deformation, pushing the moving block 47 to slide in the opposite direction, and the positioning plate 412 returns to its original position. Through this periodic movement, the positioning plate 412 can adjust its position in real time according to the dynamics of the printed matter's transport, accurately positioning the printed matter and preventing it from shifting during transport.

[0040] During the operation of the positioning mechanism 4, the moving block 47 moves back and forth continuously. Since the squeezing rod 51 is fixed on the outside of the moving block 47 and located on the outside of the elastic airbag 53, when the moving block 47 moves towards the elastic airbag 53, the squeezing rod 51 will squeeze the elastic airbag 53. After the elastic airbag 53 is squeezed, the internal gas is compressed. This compressed gas is transported to the jet plate 55 through the air guide pipe 54. The jet plate 55 is fixed above the conveyor belt 32, and its inner wall is provided with densely packed small holes. The compressed gas is ejected at high speed from the small holes, forming an airflow to sweep the surface of the conveyor belt 32. While the printed matter is being transported and positioned, the cleaning mechanism 5 continues to work, promptly blowing away the impurities attached to the conveyor belt 32 to avoid contaminating the subsequent printed matter and ensuring the quality of the printed matter.
