Description

Technical Field

[0001] This utility model belongs to the field of ink printing technology, specifically relating to a water-based ink printing device. Background Technology

[0002] Water-based printing inks, also known as liquid inks or flexographic water-based inks, are homogeneous pastes primarily composed of water-soluble resins, organic pigments, solvents, and related additives, processed through compounding and grinding. The binder provides the necessary transfer properties, while the pigments impart color. The binders in water-based printing inks are mainly divided into two types: water-dilutable and water-dispersible. Water-based inks are particularly suitable for packaging printing products with strict hygiene requirements, such as those for tobacco, alcohol, food, beverages, pharmaceuticals, and children's toys.

[0003] In existing technologies, when using water-based inks for printing, anilox rollers, ink fountain rollers, and printing plate cylinders are used together to drive the ink onto the material. However, if the water-based ink contains large particles or insoluble impurities, these substances may get stuck in the ink holes when passing through the anilox roller, resulting in a decrease in ink transfer performance or even severe clogging of the anilox roller, thus reducing the printing quality. Utility Model Content

[0004] The purpose of this invention is to provide a water-based ink printing device that can stir, crush, and filter the ink through a filter cylinder before the ink is conveyed to the anilox roller, thereby reducing ink particles and removing impurities, preventing the anilox roller mesh from clogging, and the filter cylinder can be disassembled or installed at any time, thus enabling convenient cleaning and maintenance of the filter cylinder and reducing maintenance costs.

A side-symmetrical fixed plate 121 is fixedly connected. An stirring blade 126 is fixedly connected to the outer wall of the rotating shaft 107 and inside the filter cylinder 105. An array of insert strips 125 are fixedly connected to the outer wall of the filter cylinder 105. One of the insert strips 125 is slidably fitted with the support rod 103. A through groove 122 is opened at one end of the ink fountain 1 for the insert strip 125 to fit into. A through hole 118 is opened through the middle of the insert strip 125. A retaining ring 116 is fixedly connected to one side of the ink fountain 1. An insert rod 110 is fixedly connected in an array on one side of the retaining ring 116 for movably fitting into the through hole 118. A feed inlet 119 is opened through the side of the filter cylinder 105.

[0024] According to the above structure, the insert strip 125 is aligned with the through groove 122 and the through hole 118 is aligned with the insert rod 110, so that the filter cylinder 105 is embedded in the ink fountain 1, and one of the insert strips 125 is slidably embedded in the support rod 103. The support rod 103 provides auxiliary support for the insert strip 125. The filter cylinder 105 is located below the dustproof plate 102 at this time. One end of the filter cylinder 105 is connected to the retaining ring 116. After the ink is poured into the ink fountain 1, it enters the interior of the filter cylinder 105 through the feed port 119.

[0025] Refer to the attached Figures 2-6A gear 111 is fixedly connected to one end of the anilox roller 101 and to one side of the ink fountain 1. A gear 2 112 and a gear 3 113 are rotatably connected to one side of the ink fountain 1. Gear 111 meshes with gear 2 112, and gear 2 112 meshes with gear 3 113. A fixing plate 114 is fixedly connected to one side of the ink fountain 1 and to the outside of the retaining ring 116. A gear 4 115 is rotatably connected to one side of the fixing plate 114. Gear 3 113 meshes with gear 4 115. A connecting post 123 is fixedly connected to one side of gear 4 115. The middle part of the connecting column 123 is provided with a groove 124 for the movable fitting of the insert plate 121. The filter cylinder 105 is provided with a discharge port 120 through it on the side opposite to the feed port 119. The inner wall of the discharge port 120 is fixedly connected with a screen 117. A rotating rod 108 is connected to one side of the ink fountain 1 and the side of the through groove 122 with damping rotation. A limiting plate 109 for pressing the insert strip 125 is fixedly connected to the outer wall of the rotating rod 108. One end of the insert rod 110 protrudes from the ink fountain 1. A baffle 106 is fixedly connected in an array on one side of the cover 104.

[0026] According to the above structure, after the cover 104 is screwed to the filter cylinder 105, one end of the rotating shaft 107 passes through the filter cylinder 105, and the insert rod 110 is located on one side of the baffle 106 to limit it and prevent the cover 104 from rotating and loosening. Rotating the rotating rod 108 causes the limiting plate 109 to rotate to one side of the insert strip 125 to fix it and prevent the insert strip 125 and the filter cylinder 105 from moving outward. The insert plate 121 is embedded in the insert groove 124. When the anilox roller 101 rotates, it drives the gear one 111 to rotate. The gear one 111 drives the gear two 112 to rotate. The gear two 112 drives the gear three 113 to rotate. The gear three 113 drives the gear four 115 to rotate. The gear four 115 drives the gear three 115 to rotate. The connecting column 123 rotates, thereby causing the rotating shaft 107 and the stirring blade 126 to rotate and stir the ink. The fixing plate 114 supports the gear 115. The stirring blade 126 continuously pushes the ink towards the screen 117, allowing it to flow below the anilox roller 101. The ink is then transferred to the anilox roller 101 via the ink fountain roller. This invention can stir, crush, and filter the ink through the filter cylinder 105 before it is transferred to the anilox roller 101, reducing ink particles and removing impurities, preventing the mesh of the anilox roller 101 from clogging. Furthermore, the filter cylinder 105 can be disassembled or installed at any time, making it easier to clean and maintain, thus reducing maintenance costs.

[0027] The working principle of this utility model is as follows: Align the insert strip 125 with the slot 122 and the through hole 118 with the insert rod 110, so that the filter cylinder 105 is embedded in the ink fountain 1, and one of the insert strips 125 is slidably embedded in the support rod 103. The support rod 103 provides auxiliary support for the insert strip 125. The filter cylinder 105 is located below the dustproof plate 102. One end of the filter cylinder 105 is connected to the retaining ring 116. After the ink is poured into the ink fountain 1, it enters the filter cylinder 105 through the feed inlet 119. After the cap 104 is screwed onto the filter cylinder 105, one end of the rotating shaft 107 passes through the filter cylinder 105. The insert rod 110 is then positioned on one side of the baffle 106 to limit its movement, preventing the cap 104 from rotating and loosening. Rotating the rotating rod 108 further limits its movement. Position plate 109 rotates to one side of insert strip 125 to fix its cover, preventing insert strip 125 and filter cylinder 105 from moving outward. Insert plate 121 is embedded in insert groove 124. When anilox roller 101 rotates, it drives gear one 111 to rotate. Gear one 111 drives gear two 112 to rotate. Gear two 112 drives gear three 113 to rotate. Gear three 113 drives gear four 115 to rotate. Gear four 115 drives connecting column 123 to rotate, thereby enabling rotating shaft 107 and stirring blade 126 to rotate and stir ink. Fixing plate 114 supports gear four 115. Stirring blade 126 continuously pushes ink towards screen 117, causing it to flow below anilox roller 101. The ink is then transferred to anilox roller 101 through ink fountain roller.
