Description

Technical Field

[0001] The utility model specifically relates to a device for reducing static electricity of an in-line gravure printing press. Background Technique

[0002] A printing press is a machine for printing words and images. A modern printing press generally consists of mechanisms such as plate loading, ink coating, printing, and paper feeding (including folding). Its working principle is as follows: First, the words and images to be printed are made into printing plates and installed on the printing press. Then, ink is applied to the areas with words and images on the printing plate manually or by the printing press, and then directly or indirectly transferred to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wood boards, glass, and ceramics), thereby replicating the same printed matter as the printing plate.

[0003] When eliminating static electricity from printed matter of different thicknesses, the required distance between the ion air bar and the printed matter is different. Currently, the ion air bar has a fixed position and cannot be adjusted, resulting in low practicability. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for reducing static electricity of an in-line gravure printing press to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A device for reducing static electricity of an in-line gravure printing press, including a printing press body, an ion air bar, and a height adjustment component. The printing body includes two groups of support frames. The ion air bar is arranged between the two groups of support frames and is located directly above the printing material vertically.

[0006] Among them, the distance between the ion air bar and the printing material is adjusted through the height adjustment component according to the thickness of the printing material to achieve static electricity elimination.

[0007] Preferably, the height adjustment component includes a motor arranged on the inner side of one of the support frames. A first housing is arranged vertically below the motor, and a through hole adapted to the power output end of the motor is provided on the upper surface of the first housing.

[0008] Preferably, a threaded rod is arranged in the inner cavity of the first housing. A bearing sleeve is sleeved outside the threaded rod, and the power output end of the motor extends into the cavity through the through hole and is connected to the threaded rod.

[0009] Preferably, a first sliding groove is provided on the side of the first housing away from the support frame. A first connecting plate is arranged outside the bearing sleeve. The first connecting plate extends outside the first housing through the first sliding groove and is connected to the ion air bar.

[0010] Preferably, the height adjustment component further includes a second housing disposed on the other set of support frames, and a second chute is formed on one side of the second housing facing the first housing.

[0011] Preferably, a slide bar is disposed in the inner cavity of the second housing, and a slide sleeve is sleeved outside the slide bar.

[0012] Preferably, a second connection plate is disposed outside the slide sleeve, and the second connection plate extends outside the second housing through the second chute and is connected to the other side of the ion wind bar.

[0013] Technical effects and advantages of the present utility model: For the device for reducing static electricity of the unit type intaglio printing machine, after the printing material is printed, the staff can adjust the distance between the ion wind bar and the printing material according to the thickness of the printing material. The power output end of the motor drives the threaded rod to rotate, driving the bearing sleeve to rotate accordingly. The slide sleeve slides on the slide bar, thereby restricting the rotation of the bearing sleeve and converting the rotational motion into a linear motion, so that the ion wind bar follows the bearing sleeve to move up and down on the threaded rod, approaching or moving away from the printing material, thereby adapting to different thickness printed products for static electricity elimination, and the operation is very convenient during adjustment.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

[0021] In order to adapt to different thickness printed products, refer to Figure 1 , Figure 2 ,Figure 3 and Figure 4 As shown, it includes a printing press body 1, an ion wind bar 2 and a height adjustment component. The printing body includes two groups of support frames 3. The ion wind bar 2 is arranged between the two groups of support frames 3 and is located directly above the material to be printed vertically. Among them, the distance between the ion wind bar 2 and the printing material is adjusted through the height adjustment component according to the thickness of the printing material to achieve static electricity elimination. After the printing material is printed, the staff can adjust the distance between the ion wind bar 2 and the printing material according to the thickness of the printing material. The power output end of the motor 4 drives the threaded rod 6 to rotate, driving the bearing sleeve 7 to rotate accordingly. The sliding sleeve 11 slides on the sliding rod 10 to limit the rotation of the bearing sleeve 7, converting the rotational motion into a linear motion, so that the ion wind bar 2 follows the bearing sleeve 7 to move up and down on the threaded rod 6, approaching or moving away from the printing material, so as to adapt to printed products of different thicknesses for static electricity elimination

[0022] To facilitate the adjustment of the position of the ion wind bar 2, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, the height adjustment assembly includes a motor 4 disposed on the inner side of one set of support frames 3. A first housing 5 is provided directly below the motor 4 in the vertical direction. The upper surface of the first housing 5 is provided with a through hole adapted to the power output end of the motor 4. Through the through hole, the power output end of the motor 4 can extend into the cavity of the first housing 5 and be connected to a threaded rod 6 to drive the threaded rod 6 to rotate. A threaded rod 6 is disposed in the cavity of the first housing 5. A bearing sleeve 7 is sleeved outside the threaded rod 6. The power output end of the motor 4 extends into the cavity through the through hole and is connected to the threaded rod 6. A first sliding groove is provided on one side of the first housing 5 away from the support frame 3. A first connecting plate 8 is provided outside the bearing sleeve 7. The first connecting plate 8 extends outside the first housing 5 through the first sliding groove and is connected to the ion wind rod 2. After the threaded rod 6 rotates, the bearing sleeve 7 should rotate accordingly. However, by sliding the sliding sleeve 11 on the sliding rod 10, the rotation of the bearing sleeve 7 is limited, so that the rotational motion is converted into a linear motion, and the bearing sleeve 7 can move on the threaded rod 6, thereby driving the movement of the ion wind rod 2. The height adjustment assembly further includes a second housing 9 disposed on the other set of support frames 3. A second sliding groove is provided on one side of the second housing 9 facing the first housing 5. A sliding rod 10 is disposed in the cavity of the second housing 9. A sliding sleeve 11 is sleeved outside the sliding rod 10. The rotation of the bearing sleeve 7 is limited as the sliding sleeve 11 moves. A second connecting plate 12 is provided outside the sliding sleeve 11. The second connecting plate 12 extends outside the second housing 9 through the second sliding groove and is connected to the other side of the ion wind rod 2. After the first connecting plate 8 and the second connecting plate 12 slide along the length directions of the first sliding groove and the second sliding groove respectively, the ion wind rod 2 can be driven to move.

[0023] During use, first, the staff can adjust the distance between the ion wind rod 2 and the printing material according to the thickness of the printing material. The power output end of the motor 4 drives the threaded rod 6 to rotate, driving the bearing sleeve 7 to rotate accordingly. By sliding the sliding sleeve 11 on the sliding rod 10, the rotation of the bearing sleeve 7 is limited, converting the rotational motion into a linear motion, so that the ion wind rod 2 moves up and down on the threaded rod 6 following the bearing sleeve 7, approaching or moving away from the printing material.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
