Description

Technical Field

[0001] The utility model relates to the technical field of printing machine equipment, in particular to a water-ink balancing mechanism of a printing machine. Background Art

[0002] Ink and water balance is a printing method that uses the two major laws of oil and water immiscibility and selective adsorption of the printing plate to keep the ink and water on the printing plate in balance to achieve dot transfer, thereby achieving the effect of clear images and rich colors in printed products. In a printing machine, in order to achieve the above printing effect, an ink and water balance mechanism is needed to achieve ink and water balance during the printing process.

[0003] The commonly used water-ink balance mechanism mainly uses an inking roller, and a mixing roller abutting against the inking roller. The inking roller transfers the ink in the ink tank to the mixing roller, and the water supply component transfers water to the mixing roller as needed. The water supply component includes a water tank, a water supply roller, and a squeezing roller installed on the frame. A sponge layer is sleeved on the water supply roller, so that the sponge layer contacts the water in the water tank, the sponge layer absorbs water, and then transfers the water to the mixing roller by rotation. When it is necessary to reduce the moisture on the sponge layer, the squeezing roller is directly adjusted by the screw to reduce the gap between the squeezing roller and the sponge layer, and the water left on the sponge layer will also become smaller, so that the amount of water transferred to the mixing roller is also reduced accordingly. Conversely, the distance between the squeezing roller and the sponge layer is increased, so as to achieve the water-ink balance adjustment during the printing process. However, during use, since the surface of the mixing roller will adhere to the ink after contacting the printing roller, the adhered ink will affect the distribution of the subsequent mixed water. Therefore, during use, the existence of the ink adhered to the mixing roller will affect the distribution of the subsequent mixed water, and then affect the quality of the printed product.

[0004] Based on this, those skilled in the art provide a water-ink balancing mechanism for a printing press to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0042] As the instruction manual Figure 1-Figure 9 As shown, the utility model provides a technical solution:

[0043] A printing press ink balance mechanism comprises a frame 1, an adjustment component 2 and an auxiliary component 3; wherein: the frame 1 is an H-shaped frame structure, comprising two symmetrically arranged vertical plates 105, and a water supply roller 101, a printing roller 102, a mixing roller 104 and an ink supply roller 103 arranged between the two vertical plates 105; the adjustment component 2 is arranged inside the water supply roller 101; the auxiliary component 3 is arranged on the lower side of the mixing roller 104, and is used to remove the ink adhering to the surface of the mixing roller 104.

[0044] It should be noted that, in this embodiment, through the arrangement of the above-mentioned frame 1, adjustment component 2 and auxiliary component 3, a device is formed that can adjust the water-ink balance during the use of the printing press to solve the problem that the ink will stick to the surface of the existing mixing roller after contact with the printing roller, and the ink will affect the distribution of subsequent mixed water.

[0045] As a preferred embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the auxiliary component 3 includes a collecting shell 301, a scraper 302 and a discharge pipe 303; wherein: the collecting shell 301 is fixedly connected between the two vertical plates 105 on the inner side of the frame 1, the collecting shell 301 is located below the mixing roller 104, and the cross-sectional shape of the collecting shell 301 is arc-shaped; the scraper 302 is fixedly connected to the inner side of the collecting shell 301, and the upper surface of the scraper 302 is in contact with the surface of the mixing roller 104; the discharge pipe 303 is connected to one side of the collecting shell 301, and the other end of the discharge pipe 303 passes through to the outer side of the vertical plate 105.

[0046] It should be noted that, in this embodiment, the scraper 302 and the discharge pipe 303 are provided to form a structure capable of automatically scraping off the ink. When in use, since the mixing roller 104 will cause part of the ink to adhere to the surface of the mixing roller 104 after supplying water to the printing roller 102, the adhered ink can be scraped off by the scraper 302 during the rotation process, so as to keep the surface of the mixing roller 104 clean, and avoid the situation that the ink adhesion causes uneven water supply during the process of the water supply roller 101 supplying water to the mixing roller 104 due to the incompatibility of ink and water, thus affecting the water-ink balance of the printing machine; and part of the dripping water can be collected by the collection shell 301 and discharged together with the collected ink through the discharge pipe 303.

[0047] As a preferred embodiment, Figure 6 and Figure 7 As shown, the auxiliary component 3 also includes a mounting shell 305 fixedly connected to the surface of the water supply roller 101, and a filter screen 306 is fixedly connected to the inner side of the mounting shell 305.

[0048] It should be noted that, in this embodiment, the filter screen 306 is installed by the installation shell 305. Due to the setting of the filter screen 306, the discharge chamber forms a negative pressure environment compared to the absorbent cotton 210, so that the excess water absorbed by the absorbent cotton 210 can pass through the filter screen 306 and be introduced into the collection shell 301 through the conduit 304 for discharge.

[0049] As a preferred embodiment, Figure 4 , Figure 6 and Figure 7 As shown, the adjustment component 2 includes a rotating shaft 203 and absorbent cotton 210; wherein: the rotating shaft 203 is rotatably connected to the inner wall of the water supply roller 101, and evenly distributed through holes 201 are opened on the surface of the water supply roller 101; the absorbent cotton 210 is fixedly connected to the outer surface of the water supply roller 101, matching the through holes 201, and one end of the absorbent cotton 210 is fixedly connected to the inner wall of the mounting shell 305, and the surface of the rotating shaft 203 is fixedly connected to a retaining ring 202 in contact with the inner wall of the water supply roller 101.

[0050] It should be noted that, in this embodiment, the rotating shaft 203 can drive the baffle ring 202 to rotate to adjust the flow diameter of the through hole 201, thereby changing the water supply efficiency of the absorbent cotton 210 to the mixing roller 104, so as to adjust according to actual conditions and maintain a good water-ink balance state. Excess water can be absorbed by the absorbent cotton 210 and discharged through the conduit 304.

[0051] As a preferred embodiment, Figure 6 , Figure 7 and Figure 8 As shown, a connecting ring 204 is also fixedly connected to the surface of the frame 1, a notch corresponding to the through hole 201 is opened on the surface of the connecting ring 204, and a rotating block is rotatably connected to the inner side of the connecting ring 204, one end of the rotating shaft 203 passes through the frame 1 and is fixedly connected to the surface of the rotating block, and a slider 206 is slidably connected to the other side of the rotating block; a spring 205 is fixedly connected between the surface of the slider 206 and the inner wall of the rotating block, a limiting rod 207 is fixedly connected to the bottom of the slider 206, a mounting ring 208 is fixedly connected to one side of the connecting ring 204, a limiting hole 209 is opened on the surface of the mounting ring 208, and the other end of the limiting rod 207 passes through the adjacent limiting hole 209.

[0052] It should be noted that, in this embodiment, the rotating slider 206 can drive the rotating block to make the rotating shaft 203 rotate synchronously, so as to adjust the position of the baffle ring 202. By changing the blocking area of ​​the through hole 201 by the baffle ring 202, the drainage efficiency of the through hole 201 can be changed, thereby changing the water supply efficiency of the absorbent cotton 210 to the mixing roller 104, so as to facilitate adjustments according to actual conditions and maintain a good water-ink balance.

[0053] Under normal circumstances, the position of the slider 206 can be maintained under the action of the spring 205, so that the limit rod 207 passes through the limit hole 209 and the position of the slider 206 is limited under the cooperation of the two, thereby limiting the position of the rotating block and the rotating shaft 203. When adjustment is needed, pull the slider 206 to drive the limit rod 207 to separate from the limit hole 209 and rotate.

[0054] One end of the absorbent cotton 210 is fixed inside the mounting shell 305. Due to the setting of the filter screen 306, the discharge chamber forms a negative pressure environment compared to the absorbent cotton 210. The excess water absorbed by the absorbent cotton 210 can pass through the filter screen 306 and be introduced into the collection shell 301 through the conduit 304 for discharge.

[0055] When the ink-water balance mechanism of the printing press described in the utility model is in use: after the mixing roller 104 supplies water to the printing roller 102, part of the ink will adhere to its surface, which can be scraped off by the scraper 302 during the rotation, so as to keep the surface of the mixing roller 104 clean, avoid ink adhesion, and cause uneven water supply due to the incompatibility of ink and water in the process of the water supply roller 101 supplying water to the mixing roller 104, thus affecting the ink-water balance of the printing press, and part of the dripping water can be collected by the collecting shell 301 and connected to the collected ink and discharged together through the discharge pipe 303; by setting the adjusting component 2, the water supply amount of the water supply roller 101 to the mixing roller 104 can be adjusted according to the actual situation under the action of the adjusting component 2, so as to keep the ink-water balance of the printing press in a good state.
