Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to an anti-sticking paper feeding mechanism. Background Technique

[0002] In recent years, the processes of paper feeding, plate mounting, inking, printing, etc. of printing presses have become more and more intelligent and automated. When a modern printing press works, the text and images to be printed are first made into printing plates and installed on the printing press. Then, the printing press applies ink to the places with text and images on the printing plate, and then transfers them to paper or other printing substrates, so as to reproduce the same printed matter as the printing plate.

[0003] As the paper feeding component of a modern printing press, the paper feeding device generally takes out single sheets of cardboard stacked together in sequence and transports them into the printing press for printing work. However, the existing paper feeding devices generally feed paper by overall translation. However, the printed paper stacked together may adhere due to static electricity. When transporting the topmost paper, the lower papers often follow the upper paper and are difficult to separate, requiring the staff to pause for separation, reducing the printing efficiency. If not separated, it may cause errors in the printing work, not only increasing the workload of the staff, but also having an adverse impact on the production efficiency;

[0004] The characteristics of printing paper are good printing adaptability and high opacity. During the process of transporting printing paper by the paper feeding device, dust and some foreign objects may fall and be adsorbed on its surface. However, the existing paper feeding mechanism cannot clean the surface of the paper during the paper transportation process. If the dust on the cardboard is not removed cleanly, it will cause uneven printing, which will greatly affect the final printing effect of the cardboard. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-sticking paper feeding mechanism to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an anti-sticking paper feeding mechanism, including a housing and a paper placing table fixed to one side of the bottom of its inner wall, and further including: a paper feeding mechanism arranged in the middle of the bottom of the inner wall of the housing, the other side of the bottom of the inner wall of the housing is fixedly connected with a transfer table, the top of the housing is provided with a spraying mechanism, one side of the top of the inner wall of the housing is fixedly connected with a mounting frame, and one side of the bottom of the mounting frame is fixedly connected with a mounting shell, and a swinging mechanism is arranged on one side of the mounting shell;

A positioning plate is movably connected to the bottom of the fixed plate. A cleaning plate is fixedly connected to the bottom of the positioning plate.

[0008] Preferably, the spraying mechanism includes a water storage tank fixed to one side of the shell and a water pump communicated with the top thereof, and further includes an atomizing nozzle communicated with the water outlet of the water pump.

[0009] Preferably, the swinging mechanism includes a rotating motor installed inside the mounting shell and a positioning ring fixed to one side of its output shaft, and further includes a universal ball valve installed at the opening of the positioning block inside the positioning ring and a connecting rod fixed to one side thereof.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1-6As shown in the figure, an anti-adhesion paper feeding mechanism includes a housing 1, which is used to install parts and support the overall device. On one side of the bottom inner wall of the housing 1, a paper placing table 2 is fixedly connected. The paper placing table 2 is used to place printed paper. In the middle of the bottom inner wall of the housing 1, a paper feeding mechanism 3 is arranged. The horizontal position of one side of the top of the paper placing table 2 is flush with the paper feeding inlet of the paper feeding mechanism 3. The paper feeding mechanism 3 is located on one side of the paper placing table 2. The paper feeding mechanism 3 is used to orderly convey the printed paper placed on the top of the paper placing table 2. On the other side of the bottom inner wall of the housing 1, a conveying table 4 is fixedly connected. The conveying table 4 is located on one side of the paper feeding mechanism 3. The top of the conveying table 4 is at the same horizontal position as the paper outlet of the paper feeding mechanism 3. The conveying table 4 is used to provide a moving space for the printed paper to prevent the paper conveyed by the paper feeding mechanism 3 from falling. On the top of the housing 1, a spraying mechanism 5 is arranged. The spraying mechanism 5 is used to spray water mist inside the housing 1 when conveying the printed paper for electrostatic elimination treatment to prevent the printed paper from sticking due to static electricity and affecting the paper feeding effect. On one side of the top inner wall of the housing 1, a mounting bracket 6 is fixedly connected. The mounting bracket 6 is used to install parts. On one side of the bottom of the mounting bracket 6, a mounting shell 7 is fixedly connected. The mounting shell 7 is used to install parts and position them. On one side of the mounting shell 7, a swinging mechanism 8 is arranged. The swinging mechanism 8 is used to drive the parts on one side to swing. On the other side of the bottom of the mounting bracket 6, a fixed shell 9 is rotatably connected. The fixed shell 9 is used to position the parts. On both sides of the fixed shell 9, connecting frames 10 are rotatably connected. The connecting frames 10 are used in cooperation with the swinging mechanism 8. By the cooperation of the swinging mechanism 8 and the connecting frames 10, the parts on one side are driven to swing. Inside the inner wall of the fixed shell 9, a fixed frame 11 is fixedly connected. On one side of the bottom of the fixed frame 11, a through groove is opened. The fixed frame 11 is used to install and position the components of the spraying mechanism 5. By the cooperation of the swinging mechanism 8 and the connecting frames 10, the fixed shell 9 is controlled to drive the components of the spraying mechanism 5 to swing, expanding the spraying range of the spraying mechanism 5. Uniform swinging makes the spraying more uniform, improving the electrostatic elimination effect on the printed paper. Below one side of the inner wall of the housing 1, a fixing plate 12 is fixedly connected. The fixing plate 12 is located above the top of the conveying table 4. On both sides of the surface of the fixing plate 12, positioning shells 13 are sleeved. Inside the positioning shells 13, a limiting mechanism 14 is arranged. The limiting mechanism 14 is used to limit the parts at the bottom. By changing the position of the components of the limiting mechanism 14, the limitation on the parts at the bottom of the fixing plate 12 is released, facilitating the disassembly and assembly of the parts at the bottom. In cooperation with the positioning shells 13, the bottom of the fixing plate 12 is movably connected with a positioning plate 15. The positioning plate 15 is used to install parts. The positioning shells 13 are used in cooperation with the limiting mechanism 14 and the positioning plate 15. At the bottom of the positioning plate 15, a cleaning plate 16 is fixedly connected. The cleaning plate 16 is used to clean the surface of the printed paper to prevent the dust on the surface of the printed paper from affecting the subsequent printing effect. Through the setting of the limiting mechanism 14, it is convenient to replace the cleaning plate 16, effectively improving the use effect of the cleaning plate 16.

[0024] The spraying mechanism 5 includes a water storage tank 51 fixed to one side of the housing 1. The top of the water storage tank 51 is provided with a water inlet. The top of the water storage tank 51 is communicated with a water pump 52. The water pump 52 is located at the top of the housing 1, and the water outlet pipe of the water pump 52 penetrates through the top of the housing 1. The water outlet pipe of the water pump 52 is embedded in the inner part of the through groove of the fixing frame 11. The water outlet of the water pump 52 is communicated with an atomizing nozzle 53. The atomizing nozzle 53 is located above the paper placing table 2. The clear water stored in the water storage tank 51 is pumped out by the water pump 52 and sprayed out through the atomizing nozzle 53 to spray water mist for electrostatic elimination treatment inside the housing 1, so as to avoid the printed paper being adhered due to static electricity and affecting the normal transmission.

[0025] The swinging mechanism 8 includes a rotating motor 81 installed inside the installation shell 7. The output shaft of the rotating motor 81 penetrates through the installation shell 7 and is fixedly connected with a positioning ring 82. Both sides of the inner wall of the positioning ring 82 are fixedly connected with fixing blocks, and the fixing blocks are arranged to be inclined inward, and one side of the fixing blocks is open. A universal ball valve 83 is installed at the opening of the positioning block inside the positioning ring 82. One side of the universal ball valve 83 is fixedly connected with a connecting rod 84. One end of the connecting rod 84 is fixedly connected with the connecting frame 10. By controlling the rotation of the positioning ring 82 by the rotating motor 81, while the positioning ring 82 rotates, the universal ball valve 83 is driven to rotate synchronously by the fixing blocks. Through the setting of the universal ball valve 83, under the interaction of the connecting rod 84 and the connecting frame 10 during rotation, the fixed shell 9 and the connecting frame 10 are pushed to swing, so as to expand the spraying range of the atomizing nozzle 53, make the sprayed water mist more uniform, and improve the electrostatic elimination effect.

[0026] The limiting mechanism 14 includes limiting blocks 141 sliding on both sides inside the positioning shell 13. One side of the limiting block 141 is fixedly connected with a compression spring 142. The compression spring 142 is located inside the positioning shell 13. Slots 143 are opened on both sides of the bottom of the inner wall of the positioning plate 15. The positions of the slots 143 correspond to the positioning shell 13. The inner wall of the slot 143 is movably connected with the bottom of the positioning shell 13. Limiting grooves 144 are opened on both sides of the inner wall of the slot 143. The positions of the limiting grooves 144 correspond to the bottom of the limiting block 141. The inner wall of the limiting groove 144 is movably connected with the bottom of the limiting block 141. Under the action of the compression spring 142, the two limiting blocks 141 are simultaneously squeezed inward to make the limiting blocks 141 enter the inside of the positioning shell 13. Then, the slot 143 is aligned with the bottom of the positioning shell 13, and the positioning plate 15 is sleeved on the bottom of the fixing plate 12. Then, the limiting blocks 141 are released, and the bottom of the limiting blocks 141 is embedded in the inside of the limiting groove 144 to limit the positioning plate 15, and then the cleaning plate 16 can be installed. Similarly, by squeezing the limiting blocks 141, the positioning plate 15 can be released from the limit to disassemble and replace the cleaning plate 16. The operation is simple, which is convenient for the staff to replace the cleaning plate 16 and avoid the residual dust at the bottom of the cleaning plate 16 affecting the cleaning effect of the surface of the printed paper.

[0027] It should be noted that: The paper feeding mechanism 3 proposed in this technical solution is a prior art, and the working principle and beneficial effects during use will not be elaborated here.

[0028] Working principle: First, place the printed paper on the top of the paper placing table 2, and then turn on the water pump 52 and the rotating motor 81. The paper feeding mechanism 3 is used to convey the printed paper. While conveying, the atomizing nozzle 53 sprays water mist inside the housing 1. At the same time, under the action of the rotating motor 81, the positioning ring 82 is controlled to drive the universal ball valve 83 to rotate. Through the setting of the universal ball valve 83, while rotating, under the interaction of the connecting rod 84 and the connecting frame 10, the fixed housing 9 and the connecting frame 10 are pushed to swing, making the spraying more uniform. When a single printed paper is conveyed to the top of the conveying table 4, the surface of the paper is cleaned by the cleaning plate 16 to avoid dust residue affecting the printing effect. When dust accumulates at the bottom of the cleaning plate 16, it needs to be replaced. When replacing the cleaning plate 16, by pressing the limiting block 141 inward, the bottom of the limiting block 141 is disengaged from the limiting groove 144, and then the positioning plate 15 and the dirty cleaning plate 16 can be removed. Then, take a clean cleaning plate 16, align the card slot 143 with the bottom of the positioning housing 13, and then press the limiting block 141 again to sleeve the card slot 143 on the bottom of the positioning housing 13. Then release the limiting block 141, and the bottom of the limiting block 141 is embedded in the internal of the limiting groove 144 to limit the positioning plate 15, and the cleaning plate 16 can be installed.
