Technical Field
[0001] This utility model relates to the field of printing press technology, and in particular to a rotary printing press. Background Technology
[0002] A rotary printing press is a device that uses a rotating drum to transfer ink onto paper. When using the printing press, the paper passes through a limit roller and a rotating roller. Ink is applied to the printing plate cylinder by the coating roller, which then presses the pattern onto the rubber blanket driven by the rubber roller. The impression cylinder then precisely transfers the ink onto the paper, allowing for efficient printing.
[0003] The inventors discovered in their daily work that printing presses still have at least the following problems: When using a printing press, after the paper passes through the limiting roller and the rotating roller, ink is applied to the printing plate cylinder by the coating roller, which then squeezes the pattern onto the rubber blanket driven by the rubber roller. Subsequently, the impression cylinder accurately transfers the ink to the paper, which allows for good printing. However, in actual use, when the paper is stretched open by the limiting roller, dust may fall onto the paper, which may affect the printing. Utility Model Content

[0027] Example 1, such as Figure 1-4 As shown, a rotary printing press has a support plate 2 fixedly connected to one side of a support frame 1. A connecting roller 3 is provided on one side of the support plate 2. A limiting roller 4 is uniformly inserted into one side of the inner wall of the support frame 1. A coating roller 5 is provided on one side of the inner wall of the support frame 1. A printing plate roller 6 is rotatably inserted into one side of the coating roller 5. A rubber roller 7 is uniformly inserted into the inner wall of the support frame 1. A rubber blanket 10 is fitted over the surface of the two rubber rollers 7. An impression roller 11 is provided in the middle of the rubber blanket 10. The impression roller 11 is rotatably inserted into the inner wall of the support frame 1 and is located at the top of one side of the inner wall of the rubber blanket 10. A cleaning device 8 is provided on the inner wall of the support frame 1. A support device 9 is provided at the bottom of the support plate 2. When the printing press is used, after the paper passes through the limiting roller 4 and the rotating roller, ink is applied to the printing plate roller 6 by the coating roller 5, which then squeezes the pattern onto the rubber blanket 10 driven by the rubber roller 7. Subsequently, the impression roller 11 accurately transfers the ink to the paper, thus enabling efficient printing.
[0028] Reference Figure 2 and Figure 3The cleaning device 8 includes a sliding plate 803. A positioning plate 801 is fixedly connected to the inner wall of the support frame 1. A groove 802 is provided on the inner wall of the support frame 1. The inner wall of the groove 802 is slidably connected to the sliding plate 803. The sliding plate 803 is located on top of the positioning plate 801. A sponge strip 804 is provided at the bottom of the sliding plate 803. When using the cleaning device 8, the paper is placed on top of the positioning plate 801, and then the sliding plate 803 is slid downward on the inner wall of the groove 802, thereby making the paper... The sponge strip 804 is pressed against the surface of the paper. When the paper passes through the card plate 801, the sponge strip 804 can effectively clean the dust that falls on the paper surface. A first damping rod 805 is fixedly connected to the bottom of the inner wall of the slide groove 802. The top of the first damping rod 805 is fixedly connected to the bottom of the sliding plate 803. A first spring 806 is sleeved on the surface of the first damping rod 805. One end of the first spring 806 is fixedly connected to the bottom of the inner wall of the slide groove 802. The first spring 806 is close to the first damping rod 805. One end of 05 is fixedly connected to the bottom of the sliding plate 803. The first spring 806 pulls the sliding plate 803 towards the slide groove 802, thereby causing the sponge strip 804 to press against the surface of the paper. A rectangular frame 808 is fixedly connected to the bottom of the sliding plate 803. A rectangular plate 809 is slidably connected to the inner wall of the rectangular frame 808. The bottom of the rectangular plate 809 is fixedly connected to the top of the sponge strip 804. A rubber plate 810 is fixedly connected to the inner wall of the rectangular frame 808. The rubber plate 810 is positioned within the rectangular frame 803. The rectangular plate 809 is slid to the inner wall of the rectangular frame 808, and then the rectangular plate 809 is pressed against the side of the sponge strip 804 near the rectangular frame 808. The directional operation facilitates the replacement of the sponge strip 804. The inner wall of the support frame 1 is evenly rotated and inserted with positioning rollers 807. The positioning rollers 807 are set on the side of the sliding plate 803 near the limiting roller 4. The paper passes between the two positioning rollers 807, which makes it easy for the paper to enter the top of the card plate 801 horizontally.
[0029] Reference Figure 4The support device 9 includes a support frame 901, which is located on the side of the support frame 1 near the support plate 2. The support frame 901 is positioned at the bottom of the support plate 2. When using the support device 9, the support frame 901 on one side of the support frame 1 is positioned at the bottom of the support plate 2 to facilitate support of the support plate 2. A fixing frame 902 is fixedly connected to one side of the support frame 1. The inner wall of the fixing frame 902 is slidably connected to one side of the bottom of the support frame 901. A locking block 903 is slidably inserted through the top of the fixing frame 902. One side of the locking block 903 is located on the side of the support frame 901 away from the fixing frame 902. By sliding the bottom of the support frame 901 into the interior of the fixing frame 902, the locking block 903 passes through the top of the fixing frame 902, thus confining the support frame 901 to one side of the support frame 1. A second damping rod 904 is fixedly connected to the top of the frame 902. The top of the second damping rod 904 is fixedly connected to the bottom of one side of the locking block 903. A second spring 905 is sleeved on the surface of the second damping rod 904. One end of the second spring 905 is fixedly connected to the top of the frame 902. The end of the second spring 905 near the second damping rod 904 is fixedly connected to the bottom of one side of the locking block 903. The locking block 903 is pulled towards the frame 902 by the second spring 905, which makes it easier to set one side of the locking block 903 inside the frame 902. A rubber block 906 is fixedly connected to the top of the support frame 901. The rubber block 906 is set at the bottom of the support plate 2. The rubber block 906 can play a certain buffering role, so that the top of the support frame 901 can be tightly attached to the bottom of the support plate 2.
[0030] Working principle: When using the printing press, after the paper passes through the limiting roller 4 and the rotating roller, ink is applied to the printing plate cylinder 6 by the coating roller 5, which then presses the pattern onto the rubber blanket 10 driven by the rubber roller 7. Subsequently, the impression cylinder 11 precisely transfers the ink onto the paper, thus enabling efficient printing. When using the cleaning device 8, the paper passes between the two positioning rollers 807, facilitating its horizontal entry into the top of the clamping plate 801. The control sliding plate 803 then slides downwards along the inner wall of the slide groove 802. The first spring 806 pulls the sliding plate 803 towards the slide groove 802, causing the sponge strip 804 to press against the paper surface. As the paper passes through the clamping plate 801, the sponge strip 804 effectively cleans away dust from the paper surface. The rectangular plate 8... 09 slides to the inner wall of the rectangular frame 808, thereby squeezing the rectangular plate 809 against the side of the sponge strip 804 near the rectangular frame 808. This directional operation facilitates the replacement of the sponge strip 804. When using the support device 9, slide the bottom of the support frame 901 into the interior of the fixed frame 902, and then pass the locking block 903 through the top of the fixed frame 902. The second spring 905 pulls the locking block 903 towards the fixed frame 902, thereby making it easier to set one side of the locking block 903 inside the fixed frame 902. This makes it easier to restrict the support frame 901 to one side of the support frame 1, and then set the support frame 901 on one side of the support frame 1 at the bottom of the support plate 2, thus making it easier to support the support plate 2. The rubber block 906 can play a certain cushioning role, so that the top of the support frame 901 can be tightly attached to the bottom of the support plate 2.
[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
