Description of the embodiments
The present invention will be described in further detail with reference to the accompanying drawings and examples, but the embodiments of the present invention are not limited thereto.
Examples
As shown in each figure, the integrated continuous ink supply box with double ink backflow prevention comprises an outer box 1 and an inner box 2, wherein the outer box comprises a top cover 11 and other five panels which are integrated into a whole to form a rectangular shell 12 capable of accommodating the inner box, the top cover 11 is an opening surface of the continuous ink supply box, and is movably connected with the left side and the right side of the rectangular shell 12, so that ink is conveniently added; in addition, the production of the integrated impression of the other surfaces of the outer box 1 except the top cover 11 can greatly improve the labor productivity, and the six panels of the outer box of the traditional continuous ink supply box are produced separately and assembled manually, which is very labor-consuming, and especially under the environment with very high labor cost, how to improve the manual assembly efficiency is considered.
The inner box 2 is provided with 4 ink storage bins which are integrally connected, and the four ink storage bins are produced through an integrated die and are in place in one step. The problem of 2 can be solved here, firstly, the traditional production and film sealing of the ink storage bins are all carried out one by one, and then the ink storage bins are manually assembled into an inner box; the invention can be taken out into four ink storage bins and one sealing film at a time by only one step, and the four production and sealing films are not needed to be separated, and the traditional continuous ink supply box is very labor-consuming. Secondly, because the ink storage bin is produced independently by the traditional continuous ink supply box, and then four ink storage bins are assembled into an inner box, the inner box is easy to generate instability and deform, the printing effect is affected, and the integrated inner box is higher in stability and not easy to deform.
The ink storage bin consists of a large ink storage bin 21, a small ink storage bin 22, an air bin 24 and a one-way valve ink storage bin 23, and the problem of pressure balance in the ink storage bin is solved through the four storage bins. The large ink storage bin 21, the small ink storage bin 22 and the check valve ink storage bin 23 are communicated and arranged in front of the ink storage bin, and the air bin 24 is arranged on the back of the ink storage bin. The inner box 2 includes a top plate 39, and the top plate 39 is provided with a large ink storage bin inking hole 25, a first air inlet hole 26 and a small ink storage bin inking hole 30, wherein the small ink storage bin inking hole 30 is generally closed, and the holes are designed for convenient maintenance, such as when no ink exists, the small ink storage bin inking hole 30 is directly opened, and ink is pumped by a needle cylinder to be injected into the small ink storage bin 22 through the holes. The right lower corner of the large ink storage bin 21 is provided with a first inlet 31 of a small ink storage bin, the left upper corner of the small ink storage bin 22 is provided with a second inlet 32 of the small ink storage bin, and the first inlet 31 of the small ink storage bin and the second inlet 32 of the small ink storage bin are connected in an intercommunication way through an ink channel 33 arranged at the back of the ink storage bin. The small ink reservoir 22 is shaped as an inverted "L" having only one sixth of the area of the large ink reservoir 21 that can hold ink. The large ink storage bin 21 and the small ink storage bin 22 are internally provided with a plurality of support plates 34 with notches, the purposes are two, and firstly, the large ink storage bin 21 and the small ink storage bin 22 have certain supporting force so that the films are not easy to fall off; secondly, in order to stabilize the structure of the whole inner box, the inner box is not easy to deform.
The left side of the top end of the air bin 24 is provided with a second air inlet 27 and the right side is provided with a third air inlet 28, the second air inlet 27 and the third air inlet 28 are connected in an intercommunication way through an air channel 29, and the third air inlet 28 is communicated with the large ink storage bin 21. The air passage 29 is composed of a linear air passage 291 and a curved air passage 292, and the curved air passage 292 is composed of a plurality of S-shaped air passages connected end to end, and the curved air passage is designed to make ink backflow less easy. The second air intake hole 27 is provided at the top end of the linear air passage 291, and the third air intake hole 28 is provided at the top end of the curved air passage 292.
The design solves the problem of ink backflow well, and the specific operation flow is as follows: the large ink reservoir is filled with a large amount of ink from the ink feed holes 25 and then capped. During printing, ink enters the ink channel 33 on the back of the inner box 2 at the bottom of the large ink storage bin 21 through the first inlet 31 of the small ink storage bin, then enters the second inlet 32 of the small ink storage bin, flows into the small ink storage bin 22, then enters the one-way valve ink storage bin 23, and then enters the continuous supply pipeline. The design adds a small ink storage bin 22 and a narrow ink channel 33, because the area of the small ink storage bin 22 is very small, and the supporting plate 34 with a notch inside plays a role in ink backflow resistance, when the pressure is unbalanced, when ink flows back to the small ink storage bin 22, due to the action of earth gravity, the ink can only flow back to half of the height of the small ink storage bin 22, and the ink is difficult to flow back to the second inlet 32 of the small ink storage bin at the top end and the narrow ink channel 33, so that the ink enters the large ink storage bin 21. Some ink return is performed through the air bin 24, and in order to prevent ink from flowing back into the air bin 24, the best design point of the invention is to provide a second air inlet hole 27 and a third air inlet hole 28 at the top end of the air bin 24. The specific operation flow is as follows: air enters from the first air inlet hole 26 of the inner box top plate 39, then vertically enters the linear air channel 291 connected with the second air inlet hole 27 into the curved air channel 292 connected with the linear air channel 291, upwards enters the third air inlet hole 28, and then enters the large ink storage bin 21, so that printing is realized. The conventional air bin is designed to be one-way direct air inlet, ink is easy to flow back, another air inlet which is at the same height as the air inlet is added in the air bin, namely, air does not directly enter the large ink storage bin 21, but enters the large ink storage bin 21 after finally returning to the height of the air inlet after bypassing a linear type and curved type air channel, a third air inlet 28 connected with the large ink storage bin 21 is arranged at the top of the air bin 24, and ink is unlikely to enter the air channel at the height when flowing back, so that the ink flows back to the first air inlet 26.
In order to make the effect of preventing the ink from flowing back better, the invention can also add a check valve ink storage bin 23, wherein the check valve ink storage bin 23 is internally provided with a check valve 36, a check valve ink storage bin ink inlet 35 and a pipeline ink outlet 37 which are arranged at the top end of the check valve 36. The check valve 36 is shaped like a hollow "I", and is composed of a housing 361, a baffle 362, a spring 363 and a base 364, wherein the diameter of the baffle 362 is slightly larger than that of the ink inlet 35 of the check valve ink storage bin and is connected with the base 364 through the spring 363, and two sides of the housing 361 are hollowed out and are connected with the check valve ink storage bin 23 in an intercommunication manner. The specific operation flow is as follows: when ink enters the check valve ink storage bin 23 from the check valve ink storage bin ink inlet 35 due to air pressure during printing of the printer, the ink presses the baffle 362 downwards, the baffle 362 moves downwards, the ink flows into the shell 361 from the check valve ink storage bin ink inlet 35, and the two sides of the shell 361 are hollowed out, so that the ink directly flows into the check valve ink storage bin 23 and then flows out from the pipeline ink outlet 37 for printing. When no printing is performed, the baffle 362 seals the ink inlet 35 of the ink storage chamber of the check valve due to the elastic force of the spring 363, thereby achieving the effect that the ink cannot flow back. The check valve 36 design of the present invention also provides cost savings and labor productivity advantages, and conventional continuous supply cartridges are all of check valve design, but are all of external design, typically being individually mounted on the inner wall or on individual components of the inner case, requiring more production steps, such as creating more mounting brackets that can be mounted on the inner case wall, and such mounting requires manual installation, which is difficult due to the typically very small size of the check valve, resulting in a small number of installations per worker per day, and increased production costs. The present invention solves this problem well by designing the check valve 36 at the bottom of the ink reservoir, which is perfectly integrated with the ink reservoir, saving many production and organization procedures, and improving labor productivity.
In order to observe the use condition of the ink and the beauty of the product at any time, the front surface of the rectangular outer box shell 12 is provided with a hollow-out part for installing the observation plate 13, the front surface of the observation plate 13 is provided with four observation windows 131 and the back surface is provided with a plurality of buckles 132, and the four observation windows 131 correspond to four ink storage bins. The back of the inner box 2 is also provided with a rectangular observation board clamping groove 38, the air bin 24 is arranged inside the observation board clamping groove 38, the observation board clamping groove 38 corresponds to a plurality of buckles 132 for buckle installation, the air bin 24 exposed outside is well shielded behind the observation board 13, and meanwhile, the use condition of ink inside the ink storage bin can be observed through the observation window 131.
The foregoing is a preferred embodiment of the present invention, and simple modifications and substitutions by those of ordinary skill in the art are within the scope of the present invention.
