Abstract
Description
Technical Field
[0001] This utility model relates to an ink chamber frame structure, and more particularly to an ink chamber frame structure that can reduce ink overflow from both sides of the roller. Background Technology
[0002] A typical ink chamber frame structure is paired with an ink roller to form an ink chamber device. The ink chamber frame structure consists of an ink baffle plate, an upper doctor blade, a lower doctor blade, and two ink-blocking blocks located on either side of the ink baffle plate. Together with the ink roller, these components form a closed ink chamber device. When the ink chamber device operates, ink fills the entire ink chamber, allowing the ink roller to evenly coat its surface as it rotates. However, the two ink-blocking blocks on either side of the ink baffle plate wear down with the rotation of the ink roller, creating gaps between them and the ink roller. Therefore, if the ink-blocking blocks are not replaced regularly, the worn blocks will cause ink to spray out from these gaps, scattering ink everywhere and soiling the surrounding environment. Ink is difficult to clean, so when ink sprays out of the ink chamber, printing companies must spend considerable time and manpower on cleaning. Utility Model Content
[0003] This utility model provides an ink chamber frame structure, which is used in combination with an ink wheel to form an ink chamber device with ink return function. The ink chamber frame structure includes an ink chamber frame, two first ink blocking blocks, and a lower doctor blade. The ink chamber frame includes an upper ink chamber frame, a lower ink chamber frame, and an ink blocking plate. The upper side of the ink blocking plate is connected to the upper ink chamber frame, and the lower side of the ink blocking plate is connected to the lower ink chamber frame. An ink wheel is provided on the front surface of the ink blocking plate of the ink chamber frame, and the left and right ends of the ink wheel correspond to the left and right ends of the ink blocking plate of the ink chamber frame. The two first ink blocking blocks are disposed on the front surface of the ink blocking plate of the ink chamber frame, and the two first ink blocking blocks are respectively located near the left and right ends and near the lower side of the ink blocking plate. The lower doctor blade is disposed on the lower ink chamber frame of the ink chamber frame, and the lower doctor blade, the ink blocking plate of the ink chamber frame, the two first ink blocking blocks, and the ink wheel together form an ink chamber. Furthermore, the two first ink blocks are used to block the ink, and the ink chamber frame divides the ink chamber into one wiping area and two ink return areas using these two first ink blocks as a boundary. The wiping area is the area between the two first ink blocks, while the two ink return areas are the areas between the left and right ends of the ink baffles and the two first ink blocks. The wiping area is used to accumulate ink, and once the accumulated ink exceeds the height of the two top ends of the two first ink blocks, the ink flows over the two top ends of the two first ink blocks and is collected in the two ink return areas. This prevents ink from accumulating throughout the entire ink chamber, ensuring that there is no ink overflow between the left and right ends of the ink roller and the left and right ends of the ink baffles of the ink chamber frame during use.
[0004] The ink baffle of the ink chamber frame has at least one ink inlet hole in the ink wiping area, and the ink inlet hole is connected to an ink inlet pipe. The ink baffle of the ink chamber frame has an ink return hole in each of the two ink return areas, and the ink inlet hole is connected to an ink return pipe. Both the ink inlet pipe and the ink return pipe are connected to a circulation device, so that after the circulation device introduces the ink into the ink wiping area through the ink inlet pipe and the ink inlet hole, the excess ink flows back to the circulation device from the ink return hole and the ink return pipe in the ink return area.
[0005] The two tops of the two first ink blocks are at a first distance from the lower side of the ink baffle plate of the ink chamber frame, and the two bottoms of the two ink return holes are at a second distance from the lower side of the ink baffle plate of the ink chamber frame, the second distance being less than the first distance.
[0006] In a preferred embodiment of the present invention, two first ink block fixing brackets are further included, which are disposed on the ink block plate of the ink cavity frame and are respectively located near the left and right ends and near the lower side of the ink block plate. The two first ink blocks are detachably engaged with the two first ink block fixing brackets.
[0007] The two first ink blocks, the lower scraper of the ink chamber frame, and one surface of the ink wheel are completely in contact, so that the ink in the wiping area accumulates to the height of the two tops of the two first ink blocks.
[0008] Specifically, when the two tops of the two first ink blocks are on the same parallel line as the two tops of the two first ink block fixing brackets, and the two bottoms of the two first ink blocks are close to the lower side of the ink baffle plate of the ink cavity frame, the ink in the wiping area flows past the two tops of the two first ink blocks to the two ink return areas.
[0009] Specifically, when the two tops of the two first ink blocks are parallel to or higher than the two tops of the two first ink block fixing brackets, and there is a gap between the two bottoms of the two first ink blocks and the lower side of the ink baffle plate of the ink cavity bracket, the ink in the ink wiping area flows from the gap between the two tops of the two first ink blocks and the two bottoms of the two first ink blocks to the two ink return areas, so that the ink will not be deposited at the bottom of the ink wiping area.
[0010] In a preferred embodiment of the present invention, the invention further includes two second ink blocks and two second ink block fixing brackets; wherein the two second ink blocks are disposed at the left and right ends of the ink baffle plate of the ink cavity frame, and the two second ink blocks adhere to a surface of the left and right ends of the ink wheel to prevent ink from overflowing between the left and right ends of the ink wheel and the two second ink blocks; and the two second ink block fixing brackets are disposed on a rear surface of the left and right ends of the ink cavity frame to fix the two second ink blocks.
[0011] In a preferred embodiment of the present invention, an upper scraper is further included, which is disposed on the ink chamber frame of the ink chamber frame.
[0012] The ink chamber holder structure of this utility model has the following advantages:
[0013] 1. Reduce the occurrence of ink overflow from both ends of the ink baffle plate of the ink chamber frame and the left and right ends of the ink roller;
[0014] 2. By using a recycling device, ink consumption can be reduced; and
[0015] 3. It allows for convenient and quick replacement, reducing the manpower and time costs associated with replacing ink blocks in traditional ink chamber devices. Attached Figure Description

Detailed Implementation
[0027] Please refer to the following at the same time Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, this utility model provides an ink chamber frame structure 100, which is used to combine with an ink roller 4 to form an ink chamber device with an ink return function. The ink chamber frame structure 100 includes an ink chamber frame 1, two first ink blocking blocks 21, and a lower doctor blade 121. The ink chamber frame 1 includes an integrally formed upper ink chamber frame 11, a lower ink chamber frame 12, and an ink blocking plate 13. The upper ink chamber frame 11 is connected to the upper side 13a1 of the ink blocking plate 13, while the lower ink chamber frame 12 is connected to the lower side 13a2 of the ink blocking plate 13. An ink roller 4 is provided at the front surface 13b1 of the ink blocking plate 13 of the ink chamber frame 1, that is, at the front side of the overall ink chamber frame structure 100. The ink roller 4 is spaced a distance from the front surface 13b1 of the ink blocking plate 13 of the ink chamber frame 1, and will not contact the front surface 13b1 of the ink blocking plate 13 of the ink chamber frame 1. The left and right ends of the ink roller 4 correspond to the left and right ends 13c of the ink blocking plate 13 of the ink chamber frame 1.
[0028] The front surface 13b1 of the ink baffle plate 13 of the ink chamber frame 1 is provided with two first ink baffle blocks 21 and two first ink baffle block fixing brackets 22. The two first ink baffle blocks 21 and the two first ink baffle block fixing brackets 22 are respectively located near the left and right ends 13c and near the lower side 13a2 of the ink baffle plate 13. The two first ink baffle blocks 21 are detachably engaged with the two first ink baffle block fixing brackets 22.
[0029] Then as Figure 1 , Figure 5As shown, a lower scraper 121 is provided at the position of the lower ink chamber frame 12 of the ink chamber frame 1. The lower scraper 121 is locked to the lower ink chamber frame 12 of the ink chamber frame 1 by a lower scraper seat 122 and a plurality of fixing members. In this utility model, the ink baffle plate 13, the lower scraper 121, the two first ink baffle blocks 21 and the ink roller 4 together form an ink chamber S. The ink chamber frame 1 divides the ink chamber S into an ink wiping area S1 and two ink return areas S2 with the position of the two first ink baffle blocks 21 as the dividing line. The ink wiping area S1 is the area between the two first ink baffle blocks 21, while the two ink return areas S2 are the areas between the left and right ends 13c of the ink baffle plate 13 and the two first ink baffle blocks 21.
[0030] Furthermore, on the ink baffle plate 13 of the ink chamber frame 1, located between the two first ink baffle blocks 21, i.e., at the position of the ink wiping area S1, there is at least one ink inlet hole, which is connected to the ink inlet pipe. On the ink baffle plate 13 of the ink chamber frame 1, located between the two first ink baffle blocks 21 and the left and right ends 13c of the ink baffle plate 13, i.e., at the positions of the two ink return areas S2, there are ink return holes 131 respectively. The ink return holes 131 are connected to the ink return pipe 132, and the ink inlet pipe and the ink return pipe are connected to the circulation device.
[0031] Please refer to the above as well. Figure 8 As shown, the two first ink blocks 21 are completely in contact with the surface of the ink roller 4 and are used to block the ink O flowing into the ink wiping area S1 from flowing directly to the ink return area S2. Therefore, after the circulation device introduces the ink O into the ink wiping area S1 through the ink inlet pipe and ink inlet hole, the ink O will accumulate in the ink wiping area S1 to the two tops of the two first ink blocks 21, and will not accumulate in the entire ink cavity S. Then, the excess ink O will flow over the two tops of the two first ink blocks 21 to the two ink return areas S2, and then flow back to the circulation device through the two ink return holes 131 and the ink return pipe 132 connected to the ink return holes 131, thus achieving the function of recycling the ink O. Furthermore, the two top ends of the two first ink blocking blocks 21 are at a first distance D1 from the lower side 13a2 of the ink blocking plate 13 of the ink chamber frame 1, and the two bottom ends of the two ink return holes 131 are at a second distance from the lower side 13a2 of the ink blocking plate 13 of the ink chamber frame 1. The second distance is less than the first distance D1. Therefore, when the ink O in the self-wiping ink area S1 flows past the two top ends of the two first ink blocking blocks 21 to the two ink return areas S2, it can naturally flow into the ink return holes 131. The second distance can be zero, that is, the two bottom ends of the two ink return holes 131 are close to the lower side 13a2 of the ink blocking plate 13 of the ink chamber frame 1.
[0032] Furthermore, since the two first ink blocks 21 are detachably engaged with the two first ink block holders 22, when the first ink blocks 21 are worn due to use, new first ink blocks 21 can be quickly replaced onto the first ink block holders 22. When the two top ends of the two first ink blocks 21 are on the same parallel line as the two top ends of the two first ink block holders 22, and the two bottom ends of the two first ink blocks 21 are close to the lower side 13a2 of the ink baffle plate 13 of the ink chamber frame 1, and the ink O accumulated in the ink wiping area S1 exceeds the two top ends of the two first ink blocks 21, the ink O in the ink wiping area S1 will flow past the two top ends of the two first ink blocks 21 to the ink return holes 131 of the two ink return areas S2.
[0033] Please refer to the above as well. Figure 9 As shown, when the two top ends of the two first ink blocks 21 are parallel to or higher than the two top ends of the two first ink block fixing brackets 22, and a gap G is formed between the two bottom ends of the two first ink blocks 21 and the lower side 13a2 of the ink block plate 13 of the ink cavity bracket 1, the gap G allows the ink O accumulated at the bottom of the ink wiping area S1 to flow through, but the speed at which the ink O flows through the gap G is slower than the speed at which the ink inlet hole introduces the ink O into the ink wiping area S1. Therefore, when the ink O accumulated in the ink wiping area S1 exceeds the two tops of the two first ink blocks 21, the ink O in the ink wiping area S1 will not only flow past the two tops of the two first ink blocks 21 to the ink return holes 131 of the two ink return areas S2, but will also flow from the gap G between the two bottoms of the two first ink blocks 21 and the lower side 13a2 of the ink baffle plate 13 to the two ink return areas S2. Meanwhile, the ink O in the ink wiping area S1 will flow out from the gap G between the two bottoms of the two first ink blocks 21 and the lower side 13a2 of the ink baffle plate 13, so that ink O will not accumulate at the bottom of the ink wiping area S1.
[0034] Two second ink blocking blocks 31 are respectively provided at the left and right ends 13c of the ink baffle plate 13 of the ink chamber frame 1, and two second ink blocking block fixing brackets 32 are respectively provided on the rear surface 13b2 of the left and right ends 13c of the ink baffle plate 13. The second ink blocking block fixing brackets 32 are used to fix the second ink blocking blocks 31 on the ink chamber frame 1. The two second ink blocking blocks 31 will completely fit the surface of the ink wheel 4, so that when the ink wheel 4 is rolling, even if some ink O does not flow into the return ink hole 131 during the process of ink O flowing from the ink wiping area S1 to the return ink area S2, the two second ink blocking blocks 31 and the left and right ends of the ink wheel 4 will block the ink O, so that the ink O will not overflow between the left and right ends of the ink wheel 4 and the two second ink blocking blocks 31 and dirty the surrounding environment.
[0035] Please refer to the above as well. Figure 10As shown, the upper ink chamber frame 11 of the ink chamber frame 1 is provided with an upper scraper 111. The upper scraper 111 is locked to the upper ink chamber frame 11 of the ink chamber frame 1 by an upper scraper seat 112 and a plurality of fixing members, so that the ink roller 4 can be evenly spread on the surface of the ink roller 4 by the scraper, whether it rolls from the upper ink chamber frame 11 to the lower ink chamber frame 12 of the ink chamber frame 1 or from the lower ink chamber frame 12 to the upper ink chamber frame 11 of the ink chamber frame 1.
[0036] Furthermore, the first and second ink blocks can be composed of medium-density felt, ethylene vinyl acetate copolymer foam (EVA foam), polyethylene foam (PE foam), or ethylene propylene diene monomer (EPDM) rubber, but this invention is not limited to these. The upper scraper 111 and the lower scraper 121 can be in the form of oblique blades, thin blades, round blades, or thin pointed blades, and the upper scraper 111 and the lower scraper 121 can be replaced according to usage requirements, but this invention is not limited to the scraper styles used described above.
[0037] The ink chamber holder structure of this utility model can achieve the following effects:
[0038] 1. Reduce the occurrence of ink overflow from both ends of the ink baffle plate of the ink chamber frame and the left and right ends of the ink roller;
[0039] 2. By using a recycling device, ink consumption can be reduced; and
[0040] 3. It allows for convenient and quick replacement, reducing the manpower and time costs associated with replacing ink blocks in traditional ink chamber devices.
