Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, and particularly relates to a printing machine with adjustable printing spacing. Background Technique

[0002] A printing machine is a machine used for printing characters and images. Its working principle includes mechanisms such as plate mounting, inking, impression, and paper feeding, and it can reproduce printed matter identical to the printing plate. The invention and development of printing machines play an important role in the spread of human civilization and culture. Modern printing machines generally consist of mechanisms such as plate mounting, inking, impression, and paper feeding (including folding). Its working principle is to first make the characters and images to be printed into a printing plate, install it on the printing machine, and then apply ink to the areas with characters and images on the printing plate by manual or the printing machine, and then directly or indirectly transfer it to paper or other printing substrates.

[0003] A printing machine with adjustable printing spacing, with the authorization announcement number of CN 218876610 U in China, drives the first gear to rotate through the first toothed disk by the first motor. The first gear drives the second gear to rotate through the transmission rod, and the second gear drives the screw rod to rotate through the second toothed disk. The rotation of the screw rod controls the up and down movement of the roller shaft through the slider to achieve intermittent printing, increasing the printing styles of the printing machine and improving the printing efficiency at the same time. The roller shaft adopts a detachable rubber surface, and when the rubber surface is damaged or aged, the rubber surface can be directly replaced, avoiding unnecessary waste of replacing the entire roller shaft.

[0004] However, there are still some deficiencies in the use of this patent. During the printing process, due to the long-term use of the film material of the printing roller, the phenomenon of paper wrinkles is likely to occur during printing. The existing method of smoothing the wrinkles is generally for the staff to smooth it with the help of tools, but it is easy to damage the paper when smoothing manually, and it is impossible to smooth the paper well, which leads to printing errors and other situations during the movement and printing of the paper, greatly reducing the printing quality. In addition, the existing printing machine is prone to deviation during transmission, resulting in the consequence of printing mistakes. Content of the Utility Model

The bottom plate 1 and the fixed frame 3 are of an integral structure, and the materials of the bottom plate 1 and the fixed frame 3 are both set to stainless steel.

[0026] In this embodiment, as shown in Figure 1 and Figure 2 , a limiting assembly 2 is provided on the top of the bottom plate 1. The limiting assembly 2 includes two connecting plates 201 fixedly connected to the top of the bottom plate 1. The two connecting plates 201 are fixedly connected through a connecting block 202. A round rod 203 is fixedly connected to the side of the connecting plate 201. A first adjusting block 204 is provided on the side of the connecting plate 201. An adjusting rod 206 is fixedly connected to the side of the first adjusting block 204. The outside of the adjusting rod 206 is threadedly connected to the connecting plate 201. A moving block 205 is rotatably connected to the side of the adjusting rod 206. The moving block 205 is slidably connected to the round rod 203. A round wheel 207 is rotatably connected to the side of the moving block 205 through a connecting seat 208.

[0027] Among them, by setting the limiting assembly 2, the paper is restricted. After the paper is placed, turn the first adjusting blocks 204 on both sides. The first adjusting blocks 204 drive the adjusting rod 206 to rotate. When the adjusting rod 206 rotates, it drives the moving block 205 to move towards the middle position until the side of the paper fits against the round wheel 207. During the printing process, the round wheels 207 on both sides play a role in restricting the paper, which can effectively prevent the paper from shifting during the printing process, thus causing printing errors. At the same time, the rotation of the round wheel 207 plays a role in reducing the friction with the paper, ensuring the stable progress of the printing process.

[0028] In this embodiment, as shown in Figure 1 , Figure 3 and Figure 4As shown in the figure, the adjusting assembly 4 includes a lead screw 403 threadedly connected to a threaded sleeve 12. A second adjusting block 404 is fixedly connected to the top of the lead screw 403. The bottom of the lead screw 403 is rotatably connected to a support frame 401. A positioning rod 402 is fixedly connected to the top of the support frame 401. The positioning rod 402 is slidably connected to the fixed frame 3. A printing roller 405 is rotatably connected inside the support frame 401. A second chute 11 is formed inside the fixed frame 3. A fixing plate 5 is fixedly connected to the top of the bottom plate 1. A first chute 7 is formed on the side of the fixing plate 5. A support roller 6 is rotatably connected to the side of the fixing plate 5. An electric telescopic rod 10 is fixedly connected to the top of the bottom plate 1. A slider 8 is fixedly connected to the top of the electric telescopic rod 10. Both sides of the slider 8 are slidably connected to the first chute 7 and the second chute 11 respectively. A guide roller 9 is rotatably connected to the side of the slider 8.

[0029] Among them, by setting the adjusting assembly 4, a simple structure for adjusting the spacing is formed, which can quickly adjust the spacing of the printing machine. When printing is required, turn the second adjusting block 404 to drive the lead screw 403 to move upward, so that the spacing between the printing roller 405 and the support roller 6 becomes larger, making it more convenient to replace the paper between the printing roller 405 and the support roller 6. At the same time, it is also convenient to maintain and replace the printing roller 405, increasing the practicability. In addition, by setting the slider 8, the guide roller 9 and the electric telescopic rod 10, a tensioning structure is formed. When the paper is wrinkled or piled up, control the electric telescopic rod 10 to contract, and the paper can be tensioned. At the same time, the guide roller 9 can smooth the paper, reducing the occurrence of paper damage.

[0030] The working process of the present utility model: When using a printing machine with adjustable printing spacing designed by this solution in work, when printing is required, turn the second adjusting block 404 to drive the lead screw 403 to move upward, so that the spacing between the printing roller 405 and the support roller 6 becomes larger, making it more convenient to replace the paper between the printing roller 405 and the support roller 6. At the same time, it is also convenient to maintain and replace the printing roller 405. Then pass the paper through the top of the support roller 6 and the bottom of the guide roller 9, and then through between the two round rods 203. Turn the first adjusting blocks 204 on both sides. The first adjusting blocks 204 drive the adjusting rods 206 to rotate. When the adjusting rods 206 rotate, drive the moving blocks 205 to move towards the middle position until the side of the paper fits the round wheels 207. During the printing process, the round wheels 207 on both sides play a limiting role on the paper, which can effectively prevent the paper from shifting during the printing process, resulting in printing errors. At the same time, the rotation of the round wheels 207 plays a role in reducing the friction with the paper, ensuring the stable progress of the printing process. When the paper is wrinkled or piled up, control the electric telescopic rod 10 to contract, and the paper can be tensioned. At the same time, the guide roller 9 can smooth the paper, reducing the occurrence of paper damage.
