Description

Technical Field

[0001] This utility model relates to the field of UV printing technology, and in particular to a UV printing paper feeding device. Background Technology

[0002] The basic principle of UV printing is to use a UV printhead to spray UV ink containing a photosensitizer onto the surface of the substrate. Then, by irradiating with an ultraviolet lamp, the ink instantly transforms from a liquid to a solid state, completing the curing process. This instant curing method not only avoids ink diffusion on the substrate surface but also ensures image clarity and color reproduction. Because UV ink cures rapidly upon contact with materials such as paper or plastic, it reduces ink diffusion, thereby improving the clarity and vividness of the printed image.

[0003] In existing technologies, manual paper picking, placing, and position adjustment are time-consuming and difficult to meet the demands of high-speed UV printing, resulting in low overall production efficiency. At the same time, repeated paper picking and placing over long periods can easily lead to worker fatigue and increase the risk of operational errors. Therefore, we propose a UV printing paper picking device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a UV printing paper dispensing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A UV printing paper feeding device includes a hollow printing platform. A placement table is fixedly connected to the outer wall of the printing platform. Two electric push rods are fixedly connected to the inside of the printing platform. A U-shaped frame is fixedly connected to the top of the output end of each of the two electric push rods. A lifting frame is fixedly connected to one end of each of the two U-shaped frames. Paper rollers are rotatably connected inside each of the two lifting frames. Multiple rubber conveying sleeves are uniformly fixedly fitted on the outer wall of each of the two paper rollers. A transmission component is provided inside the printing platform.

[0007] Preferably, the transmission assembly includes two servo motors, the outer walls of the two servo motors are respectively fixedly connected to the outer walls of the two U-shaped frames, the outer walls of the output shafts of the two servo motors are each fixedly fitted with a first synchronous pulley, the outer walls of the two paper rollers are each fixedly fitted with a second synchronous pulley, and the outer walls of the first synchronous pulley and the second synchronous pulley are meshed with the same transmission belt, thereby driving the two paper rollers to rotate.

[0008] Preferably, a frame is movably mounted on the outer wall of the printing platform, a linear motor is fixedly connected to the outer wall of the frame, and a UV printing head is fixedly connected to the outer wall of the moving end of the linear motor. By setting the UV printing head, UV ink is sprayed onto the surface of the substrate through an existing peristaltic pump.

[0009] Preferably, the top of the printing platform is provided with four sliding grooves, which are connected in pairs to the outer walls of the two ends of the two lifting frames. The sliding grooves are used to assist the lifting frames in raising and lowering, thereby adjusting the height of the two paper rollers.

[0010] Preferably, roller bearings are fixedly fitted on the outer walls of both ends of the paper roller, and the outer ring of the roller bearings is fixedly connected to the outer wall of the lifting frame. The roller bearings are used to assist the paper roller in rotating stably.

[0011] Preferably, both paper rollers are located on top of the printing platform.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution adjusts the height of the lifting frame and paper rollers using an electric push rod to accommodate paper of different thicknesses. A transmission assembly enables efficient paper transport from the placement table to the printing platform. Combined with the UV printing head, the paper is automatically ejected after printing and curing. This reduces the labor intensity of manual operation, avoids the inefficiency and positioning errors caused by manual paper handling, and significantly improves the production efficiency and stability of UV printing.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 As shown, a UV printing paper feeding device is disclosed, including a hollow printing platform 1. A frame 2 is movably mounted on the outer wall of the printing platform 1 via an existing linear motor. A linear motor 14 is fixedly connected to the outer wall of the frame 2. A UV printing head 3 (XP600) is fixedly connected to the outer wall of the moving end of the linear motor 14. The linear motor 14 drives the UV printing head 3 (XP600) to move left and right. A placement table 4 is fixedly connected to the outer wall of the printing platform 1.

[0021] The printing platform 1 has two electric push rods 5 fixedly connected inside. The top of the output end of each of the two electric push rods 5 is fixedly connected to a U-shaped frame 6. One end of each of the two U-shaped frames 6 is fixedly connected to a lifting frame 7. The servo drivers of the two electric push rods 5 are connected to the same control bus and then controlled by a synchronous controller to ensure the synchronous operation of the two electric push rods 5. The top of the printing platform 1 has four sliding grooves, which are connected in pairs to the outer walls of the two lifting frames 7 at both ends.

[0022] Paper rollers 8 are rotatably connected inside both lifting frames 7. The paper rollers 8 are made of aluminum alloy. Roller bearings are fixedly fitted on the outer walls of both ends of the paper rollers 8. The outer rings of the roller bearings are fixedly connected to the outer walls of the lifting frames 7. Multiple rubber conveying sleeves 9 are evenly fixedly fitted on the outer walls of the two paper rollers 8. Both paper rollers 8 are located on the top of the printing platform 1. The rubber conveying sleeves 9 have elasticity to facilitate contact with the paper.

[0023] The printing platform 1 is equipped with a transmission assembly, which includes two servo motors 10. The outer walls of the two servo motors 10 are fixedly connected to the outer walls of the two U-shaped frames 6 respectively. The outer walls of the output shafts of the two servo motors 10 are fixedly fitted with first synchronous pulleys 11, and the outer walls of the two paper rollers 8 are fixedly fitted with second synchronous pulleys 12. The outer walls of the first synchronous pulleys 11 and the second synchronous pulleys 12 are meshed with the same transmission belt 13. The operation of the servo motors 10 causes the first synchronous pulleys 11 and the second synchronous pulleys 12 to rotate synchronously through the transmission belt 13.

[0024] Working principle: In use, the paper is placed on the placement table 4, with one end of the paper located in the lifting frame 7 in front of the placement table 4 and below multiple rubber conveying sleeves 9. As the two electric push rods 5 operate, they drive the two U-shaped frames 6 and the two lifting frames 7 to rise and fall. The rising and falling of the two lifting frames 7 can adjust the height of the two paper rollers 8 to meet the needs of conveying paper of different thicknesses, achieving the purpose of paper picking and paper output. At the same time, when picking up paper, the operation of the two servo motors 10 drives the first synchronous pulley 11 connected to it to rotate. The rotation of the first synchronous pulley 11 drives the transmission belt 13 to rotate, and the rotation of the transmission belt 13 drives the second synchronous pulley 12 to rotate, thereby driving the two paper rollers 8 to rotate. The paper first enters the printing platform 1 from the placement table 4, and then is printed and cured by the UV printing head 3. After printing is completed, the paper is output as the two paper rollers 8 rotate.

[0025] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the UV printing head 3, servo motor 10, and linear motor 14 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
