[0002] Ink is an important material used for printing, which can express patterns and texts on substrates through printing. Ink includes main components and auxiliary components, which are evenly mixed and repeatedly rolled to form a viscous colloidal fluid. When the ink storage device is canned into other small cans, the ink in the ink storage device will decrease, but the inner wall will be adhered to the ink. If it is not cleaned in time, the corresponding cover on the ink storage device needs to be removed during the subsequent use of the ink storage device, and then the inner wall of the ink storage device needs to be cleaned. During the canning work, however, during the cleaning process, the ink inside the existing ink storage device will be in contact with the air for a long time during use, that is, the ink adhered to the inner wall of the ink storage device is in contact with the air for a long time. When the ink is in contact with the air, the oxygen in the air will promote the oxidation of certain components in the ink, accelerate the surface drying process, and form a layer of hardened epidermis. The hardened ink adheres to the inner wall of the ink storage device and is difficult to clean. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0027] Example 1

[0028] An automatic cleaning ink barrel for packaging printing, such as Figure 1-3 As shown, it includes a mounting frame 1, a storage barrel 2 and a valve 11; the storage barrel 2 is mounted on the mounting frame 1, the storage barrel 2 is provided with an air inlet 2a, and the storage barrel 2 is provided with a discharge port 2b; the storage barrel 2 is connected to the valve 11;

[0029] It also includes a first connecting plate 3, an air tank 4, a first connecting pipe 5, a first air pump 6, a multi-stage push rod 7, a first DD motor 8, an extrusion plate 9 and a scraper 10; two symmetrically arranged first connecting plates 3 are fixedly connected to the storage barrel 2; all the first connecting plates 3 are commonly fixedly connected to the air tank 4; the air tank 4 is connected to the first connecting pipe 5; the first connecting pipe 5 is connected to the first air pump 6; the first air pump 6 is connected to the air inlet 2a; four multi-stage push rods 7 in an annular array are passed through the storage barrel 2; the telescopic ends of all the multi-stage push rods 7 are commonly fixedly connected to the first DD motor 8; the output shaft of the first DD motor 8 is fixedly connected to the extrusion plate 9; eight scraper strips 10 in an annular array are fixedly connected to the extrusion plate 9; the scraper strip 10 is in contact with the inner wall of the storage barrel 2.

[0030] The side surface of the extrusion plate 9 is covered with a rubber sleeve to enhance the sealing effect.

[0031] The lower device of the extrusion plate 9 is a truncated cone structure and is used for extruding ink.

[0032] The scraper bar 10 is arranged in an inclined shape and is used to scrape the ink on the inner wall of the storage barrel 2 to guide the ink and move the ink downward.

[0033] First, the staff installs the automatic cleaning ink barrel for packaging printing at the position where it is needed, and then the staff places the canning barrel under the valve 11, ready for canning. It should be noted that when the existing ink storage device is canned into the remaining small canning barrels, the ink in the ink storage device will be reduced, but the inner wall thereof will be adhered to ink. If it is not cleaned in time, the ink storage device will need to remove the corresponding cover on the ink storage device during subsequent use, and then clean the inner wall of the ink storage device before canning. However, during the cleaning process, the ink inside the existing ink storage device will be in contact with the air for a long time during use, that is, the ink adhered to the inner wall of the ink storage device will be in contact with the air for a long time. When the ink is in contact with the air, the oxygen in the air will promote the oxidation of certain components in the ink, accelerate the surface drying process, and form a layer of hardened epidermis. The hardened ink adheres to the inner wall of the ink storage device and is difficult to clean.

[0034] After the cans are placed, the staff then opens the valve 11 and controls the multi-stage push rod 7 to push the first DD motor 8 to move downward, thereby driving the extrusion plate 9 to slide downward in the storage barrel 2, and the extrusion plate 9 drives the scraper 10 to move downward, and controls the first DD motor 8 to drive the extrusion plate 9 to rotate, that is, drives the extrusion plate 9 to rotate counterclockwise from a top-down perspective, and the extrusion plate 9 drives the scraper 10 to rotate, drives the scraper 10 to rotate and move downward in line with the inner wall of the storage barrel 2. Since the scraper 10 is arranged in an inclined shape, the scraper 10 drives the ink on the inner wall of the storage barrel 2 to move downward, that is, the scraper 10 scrapes the ink on the inner wall of the storage barrel 2 to prevent the ink from adhering to the inner wall of the storage barrel 2, and controls the first air pump 6 to operate through the air inlet 2a to inject nitrogen into the storage barrel 2, so that the air pressure in the storage barrel 2 remains in a balanced state, and is protected by nitrogen to prevent the ink in the storage barrel 2 from forming a hardened epidermis after oxidation, thereby affecting the subsequent use of the storage barrel 2.

[0035] Example 2

[0036] On the basis of the above-mentioned embodiment 1, Figure 4-6As shown, it also includes an extrusion component, which includes a second connecting plate 101, a filter screen 102, a second air pump 103, a second connecting pipe 104, a third connecting plate 105, a first scraper 106 and an air bag 107; the second connecting plate 101 is fixedly connected to the telescopic rods of all the multi-stage push rods 7; the filter screen 102 is fixedly connected to the second connecting plate 101; the second air pump 103 is fixedly connected to the second connecting plate 101; the third connecting plate 105 is fixedly connected to the extrusion plate 9; the second connecting pipe 104 is fixedly connected to the third connecting plate 105; the second connecting pipe 104 is rotatably connected to the second connecting plate 101; the second connecting pipe 104 is communicated with the second air pump 103; the third connecting plate 105 is fixedly connected to the air bag 107; four first scrapers 106 in an annular array are inserted on the air bag 107; all the first scrapers 106 are fixedly connected to the third connecting plate 105.

[0037] The first scraper 106 is configured in an arc-shaped structure for stirring the ink.

[0038] When the airbag 107 is in a contracted state, that is, the airbag 107 is attached to the first scraper 106, it is used to cooperate with the first scraper 106 to stir the ink. When the airbag 107 is in an expanded state, that is, the airbag 107 has an elliptical structure, it is used to squeeze the ink at the bottom of the storage barrel 2.

[0039] During the canning process, the squeezing plate 9 drives the third connecting plate 105 to rotate, the third connecting plate 105 drives the first scraper 106 to rotate, and the first scraper 106 drives the airbag 107 to rotate. It should be noted that in the initial state of the airbag 107, the storage contraction state of the airbag 107, that is, the airbag 107 is attached to the first scraper 106, that is, the first scraper 106 drives the airbag 107 to stir the ink in the storage barrel 2, that is, regularly stir the ink on the surface of the storage barrel 2 to avoid the ink from drying out and forming ink skin due to long-term storage, and to avoid the ink skin formed by drying and being difficult to clean;

[0040] When the extrusion plate 9 drives the third connecting plate 105 to move downward, the third connecting plate 105 drives the first scraper 106 to move downward close to and contact the bottom of the storage barrel 2, and then the second air pump 103 is controlled to operate, and the nitrogen in the upper space isolated from the extrusion plate 9 and the storage barrel 2 is sucked in through the filter 102, and then injected into the oral cavity composed of the third connecting plate 105, the first scraper 106 and the air bag 107 through the second connecting pipe 104, so that the air bag 107 expands and fits the lower surface of the storage barrel 2, that is, all the ink in the storage barrel 2 is discharged by extrusion to avoid ink remaining in the storage barrel 2. It should be noted that, in order to better discharge the material, the existing storage barrel 2 is mostly provided with an elliptical structure and a conical structure at the bottom for guiding the ink, but the above-mentioned method is used to enhance the guiding effect, that is, all the ink in the storage barrel 2 is discharged to avoid ink remaining in the storage barrel 2.

[0041] Example 3

[0042] Based on the above embodiment 2, Figure 7-8 As shown, a cleaning assembly is also included, which includes a third connecting pipe 201, a second scraper 202 and a second DD motor 203; the third connecting pipe 201 is rotatably connected to the discharge port 2b; four second scrapers 202 in a circular array are fixedly connected to the third connecting pipe 201; the second scraper 202 is in contact with the inner wall of the storage barrel 2; the second DD motor 203 is fixedly connected to the storage barrel 2; the output shaft of the second DD motor 203 is fixedly connected to the third connecting pipe 201; the third connecting pipe 201 is connected to the valve 11.

[0043] A rubber sleeve is provided at the connection between the third connecting pipe 201 and the discharge port 2b to enhance the sealing effect.

[0044] The second scraper 202 is arranged in an arc-shaped structure, and is used for gathering and guiding the ink when rotating, so that the ink gathers toward the discharge port 2b.

[0045] After all the ink in the storage barrel 2 is discharged, the multi-stage push rod 7 is controlled to contract and drive the expanded airbag 107 to contact the second scraper 202, and then the second DD motor 203 is controlled to drive the third connecting pipe 201 to rotate, and the third connecting pipe 201 drives the second scraper 202 to rotate and scrape the ink at the bottom of the storage barrel 2, and at the same time scrape the residual ink on the first scraper 106 and the airbag 107, and at the same time, under the guidance of the second scraper 202, the ink is discharged through the discharge port 2b, so that the storage barrel 2 remains clean, which is convenient for subsequent ink storage.
