Description

Technical Field

[0001] The utility model belongs to the technical field of printing, and in particular relates to a printing electrostatic ink absorbing device. Background Art

[0002] From an atomic point of view, plastics, paper and other materials are usually neutral. The positively charged nucleus in each atom is neutralized by the negatively charged electrons around it. When two materials are separated by pressure or friction, the electrons will be free on the surface of the material, thus generating a static area. In the printing proofing process, due to the friction between paper and ink, a certain positive or negative charge is generated on the surface. Due to the principle of like charges repel each other, the ink adsorption capacity is poor, and white spots appear, that is, "hair spots". Especially in cigarette plate proofing, small text transfer is not true, and the transition effect of the electric distribution diagram is not good, which affects the normal production proofing and quality inspection.

The patent includes a frame, a support frame is provided at one end of the bottom of the frame, a printing roller is rotatably connected to the top of the support frame, a connecting block is provided at one end of the top of the frame, a slide groove is provided in the middle of the lower end of the connecting block, a cross bar is provided in the slide groove, a compression spring is fixedly connected to the lower end of the compression spring, a connecting rod is fixedly connected to the lower end of the connecting rod, a pressure roller is rotatably connected to the lower end of the connecting rod, and a surface of the pressure roller is provided with a A metal sheet is placed, and a printed material is arranged between the silver pressing roller and the printing roller; more ink can be attached to the printed material, the transfer rate of the ink is improved, and white exposure is avoided; in addition, its structure is simple, and a good printing effect can be maintained for a long time, and the working performance is stable, but there are still the following shortcomings in actual use: from a practical point of view, the device cannot remove dust and eliminate static electricity on the surface of the printed material during the printing process, and the dust and static electricity on the surface of the printed material itself will affect the printing quality, thereby causing printing problems, reducing the practicality of the device.

[0004] Therefore, a printing electrostatic ink-absorbing device is needed to solve the problem in the prior art that dust removal and static elimination cannot be performed and printing quality is affected. Utility Model Content

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] See also Figure 1-4 The utility model provides a printing electrostatic ink absorption device, including a box body 1, a material inlet 3 is opened on the left side of the box body 1, a material outlet 5 is opened on the right side of the box body 1, a conveying mechanism 4 is arranged in the material inlet 3 and the material outlet 5, a driving device 2 is fixedly installed on the front side of the box body 1, a plate roller 201 is fixedly installed on the driving device 2 and is rotatably installed in the box body 1 through a bearing, an electrostatic rubber roller 8 is rotatably installed on the upper part of the plate roller 201 in the box body 1, an electrostatic discharge rod 7 is fixedly installed on the upper part of the electrostatic rubber roller 8 in the box body 1, and static elimination rollers 6 are rotatably installed in the box body 1 on the left and right sides of the electrostatic discharge rod 7.

[0022] By applying static electricity to the electrostatic rubber roller 8 through the electrostatic discharge rod 7 and cooperating with the conveying mechanism 4 to convey the printed material and clean the static electricity of dust, the electrostatic rubber roller 8 can ensure that the static electricity of the printed material is evenly distributed when it is conveyed to the upper part of the plate roller 201 for printing, thereby improving the uniform adsorption of the printing ink through static electricity, so as to achieve uniform printing and improve the printing quality.

[0023] Further Figure 2 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the conveying mechanism 4 includes two limiting conveying rollers 401, and the two limiting conveying rollers 401 are rotatably installed in the feed port 3 and the discharge port 5 respectively. A cleaning strip 402 is arranged in the feed port 3 on the right side of the limiting conveying roller 401 in the feed port 3. Two cleaning strips 402 are arranged, and the two cleaning strips 402 are symmetrically arranged in the feed port 3 up and down. The height between the two cleaning strips 402 is located at the same height above the limiting conveying roller 401. An electrostatic brush 4021 is fixedly connected to the surface of one side between the cleaning strips 402. The electrostatic brush 4021 is specifically made of a soft brush material, and both ends of the cleaning strip 402 are fixed at the feed port 3. A limiting groove 403 is opened in the material port 3, a slide rod 404 is slidably arranged on the cleaning bar 402 and is fixedly connected in the limiting groove 403, a spring 405 is sleeved on the outer side of the slide rod 404 and is arranged on the outer side of the cleaning bar 402, two slide rods 404 are arranged, the two slide rods 404 slide back and forth and are arranged at both ends of the cleaning bar 402 and are arranged in the limiting groove 403, two springs 405 are arranged on the slide rod 404, the two springs 405 are symmetrically arranged up and down and are arranged on the outer sides of the two cleaning bars 402, one end of the spring 405 close to the cleaning bar 402 is fixedly connected to the cleaning bar 402, and the other end of the spring 405 is connected to the box body 1 in the material port 3.

[0024] The printed material is conveyed by the limiting conveying roller 401 so that it can be conveyed conveniently and effectively, and printing is achieved in cooperation with the plate roller 201 and the electrostatic rubber roller 8 in the box 1. The elastic force of the spring 405 on the cleaning strip 402 can enable the electrostatic brush 4021 to fit closely to the surface of the printed material when the printed material is conveyed, so as to improve the dust adsorption efficiency and thereby improve the printing quality of the printed material.
