[0002] An ink printing device is a machine used to apply ink to the surface of various materials (such as paper, cloth, plastic, etc.) to form images or text. It is widely used in the printing industry, including the production of books, newspapers, magazines, packaging and other products. In order to ensure that each piece of paper is accurately aligned so that the position of the printed image and text is consistent and to avoid blurring, ghosting or position deviation of the printed image caused by paper offset, an ink printing device that prevents paper offset is required.

[0003] In the use of traditional anti-paper deviation ink printing devices, the paper is prevented from deflecting by adjusting the paper feeding speed and angle.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Specifically, in the setting of motor 1-2, it and the mounting roller 3 are respectively located on both sides of the machine base 1, and have different functions. One of the mounting rollers 3 is equipped with a raw material roller, which is responsible for the transportation of paper; the other mounting roller 3 is equipped with a collecting roller for collecting paper. In this way, the output end of motor 1-2 can drive the raw material roller on the mounting roller 3 to rotate to realize the transportation of paper. During the paper transportation process, they will be wound around the limiting roller 16, and then printed by the printing roller 6. After printing, the paper will be limited and wound by the limiting wheel 21, and finally collected at the collecting roller on the other mounting roller 3, completing During the winding process, when the paper reaches the limiting roller 16, the output end of the motor three 8 will drive the wheel disc 9 to rotate, and the wheel disc 9 drives the connecting rod two 11 through the connecting rod one 10 to swing left and right with the rotating shaft 12 as the center of the circle. The rotating shaft 12 drives the limiting roller 16 through the support rod 13 to adjust the tension of the paper. During this process, the limiting roller 16 will be limited inside the support rod 13 to ensure that the tension of the paper is appropriate. At the same time, the slider 15 will be limited inside the support rod 13 to ensure the stability of the paper. All of this is achieved through the tension of the first spring 17, so that the limiting roller 16 can support and adjust the tension of the paper.

[0033] Reference Figure 4, symmetrically arranged motors 2 are fixedly connected on both sides of the machine base 1, and the output end of the motor 2 is fixedly connected to the mounting roller 3, and a shell 18 is fixedly connected to the top of the machine base 1. The shell 18 is symmetrically arranged and fixedly connected to the top of the machine base 1. A limiting groove 24 is provided inside the shell 18, and a limiting plate 19 is arranged inside the shell 18. The outer wall of the limiting plate 19 is slidably connected to the inside of the limiting groove 24, and a frame 20 is fixedly connected to one side of the limiting plate 19. The frame 20 is rotatably connected to the limiting wheel 21, and the limiting wheel 21 is arranged in a linear array and rotatably connected to the inside of the frame 20. A telescopic rod 22 is arranged inside the shell 18, and a third spring 23 is sleeved on the outer wall of the telescopic rod 22. One end of the telescopic rod 22 and the third spring 23 are fixedly connected to one side of the limiting plate 19, and the other end of the telescopic rod 22 and the third spring 23 are fixedly connected to the inside of the shell 18;

[0034] Specifically, in the operation of the printing equipment, first, the paper is transmitted through the printing roller 6. At this time, the power output end of the motor 2 5 plays a role, driving the printing roller 6 to rotate, thereby printing on the surface of the paper. This process ensures the stability of the printing quality and the vividness of the printing effect. Next, the printed paper enters the second link, that is, the limiting process. When the paper passes through the shell 18, it will be accurately limited by the limiting device inside it. This limiting device is mainly composed of a limiting wheel 21, which accurately controls the position of the paper through the connection with the frame 2 20. The third link is the paper storage process. Under the action of the limiting wheel 21, the paper is smoothly stored by the collecting roller. In this process, the stability of the limiting wheel 21 is crucial. It needs to always be close to both sides of the paper to ensure the stable position of the paper during the transmission process.

[0035] Working principle: When the ink printing device to prevent paper deviation is used, first, the motor 1 2 and the mounting roller 3 are arranged on both sides of the machine base 1, one of the mounting rollers 3 is installed with a raw material roller, and the other mounting roller 3 is installed with a collecting roller, so the output end of the motor 1 2 drives the raw material roller on the mounting roller 3 to rotate, and the paper is wound on the limiting roller 16 and then printed by the printing roller 6, and finally wound on the collecting roller on the other mounting roller 3 through the limiting wheel 21 for winding, and then when the paper is on the limiting roller 16, the output end of the motor 3 8 drives the wheel disc 9 to rotate, and the wheel disc 9 drives the connecting rod 2 11 to swing left and right with the rotating shaft 12 as the center through the connecting rod 10, and the rotating shaft 12 drives the limiting roller 16 to adjust the tension of the paper through the supporting rod 13, and the limiting roller 16 is moved by the sliding The block 15 is limited inside the support rod 13, the slider 15 is limited inside the support rod 13 by the limiting column 14, and is supported by the tension of the first spring 17, so that the limiting roller 16 supports and adjusts the tension of the paper, and then the paper passes between the printing rollers 6, and the output end of the motor 25 drives the printing roller 6 to rotate to print the paper, and then the paper passes between the shells 18 for limitation, and is finally collected by the collecting roller. When the paper is between the shells 18, it is contacted by the limiting wheel 21, and the limiting wheel 21 is limited by the frame 20, and the frame 20 is limited inside the limiting groove 24 in the shell 18 by the limiting plate 19, and is supported by the tension of the third spring 23, so that the limiting wheel 21 can always fit on both sides of the paper to limit the paper.
