Description

TECHNICAL FIELD

[0001] The utility model relates to ink impurity cleaning device technical field, specifically a kind of convenient cleaning type ink barrel. BACKGROUND

[0002] Printing machine is the ink printing device commonly used in packaging bag production, it can be transferred to packaging bag by different printing mode (such as flexographic printing, intaglio printing etc.). Ink barrel as the core component of ink printing device, provides ink for printing process and carries out ink recovery simultaneously, so that ink is recycled.

[0003] In the process of ink recovery, often there are impurities, these impurities mainly come from two aspects.

[0004] I. Some components in ink, such as acrylic resin, ionize in aqueous ink solution and exist in liquid phase, these components change due to physical or chemical action in the recovery process, form impurities.

[0005] II. In the printing process, ink contacts with paper fiber, part of paper fiber mixes in ink, and then forms impurities.

[0006] Because impurities will increase in ink barrel, and will be deposited in the bottom of ink barrel, cause the turbidity degree of ink to be high, not conducive to later printing work. So in order to reduce the impurities in ink, usually adopt the way of small cleaning and large cleaning. Small cleaning, that is, use filter screen to salvage impurities in filter ink barrel at random. Large cleaning, that is, periodically extract ink in ink barrel, and clean the ink barrel to remove the impurities adhered to the inner wall of the ink barrel.

[0007] In actual operation, people find that even if frequent small cleaning, it is still difficult to meet the sufficient cleaning effect of impurities, the root of which lies in the existence of planktonic impurities; this kind of planktonic impurities, under the action of gravity and water environment, deposit on the planar bottom of cylindrical ink barrel, and do not adhere to the planar bottom, and will be stirred with water flow and stir the whole ink, seriously affect the cleaning operation. How to effectively and properly solve this kind of deposited planktonic impurities is a technical problem to be solved in the field in recent years.

[0008] Therefore, it can be seen that the process and mode of impurity cleaning in current ink barrel still need to be further improved. UTILITY MODEL CONTENT

[0022] 1. The unique feature of the ink barrel designed in the utility model is that the coaxial arrangement and the variable diameter design of the structure, the diameter of the upper barrel segment is larger than that of the lower barrel segment, and the two segments are connected through the tapered barrel segment, which not only facilitates the smooth flow of ink, but also ingeniously utilizes the principle of gravity to make the impurities naturally deposit and slide into the filter dish in the lower barrel segment.

At the same time, the chamfer surface is located below the inner wall surface of the tapered barrel segment, effectively preventing the backflow of impurities and enhancing the filtering effect.

[0024] 3. The long strip-shaped filter hole design on the filter dish not only increases the filter area and improves the filtering efficiency, but also makes the ink flow more evenly, reducing the waste of ink caused by blockage.

At the same time, the design of the oil seepage hole allows the ink to seep into the oil extraction cavity evenly, ensuring the continuity and stability of oil extraction.

[0027] 6. The design of the buckle and the guide groove not only realizes the stable installation of the L-shaped partition plate, but also allows it to be easily adjusted in position as needed, improving the flexibility and adaptability of the ink barrel. At the same time, this design also facilitates the disassembly and cleaning of the L-shaped partition plate, reducing maintenance costs.

[0028] 7. The design of the long strip-shaped oil seepage hole allows the ink to seep into the oil extraction cavity more evenly, avoiding the problems of difficult oil extraction or ink waste caused by uneven oil seepage.

[0029] 8. The design of the semicircular horizontal plate segment not only matches the inner diameter of the upper barrel segment, ensuring the smoothness of the ink flow, but also makes the L-shaped partition plate more stable during installation and less likely to shake.

[0030] 9. The design of the vertical plate segment with the same length as the upper barrel segment ensures that the L-shaped partition plate can completely cover the internal space of the upper barrel segment, effectively preventing the leakage of ink during extraction.

[0031] 10. The barrel cover design not only protects the internal structure of the ink barrel, but also realizes the recycling and extraction function of ink through the oil return pipe and oil extraction pipe. At the same time, the closing method of the barrel cover also ensures the sealing of the ink barrel, avoiding ink volatilization and contamination. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figs. 1-3 In this embodiment of the present invention, the ink barrel comprises a coaxially arranged upper barrel section 1 and lower barrel section 3. The diameter of the upper barrel section 1 is larger than that of the lower barrel section 3, and the upper and lower barrel sections 1 and 3 are connected to each other through a tapered barrel section 2, the aperture of which gradually decreases from top to bottom. Four support legs 31 are fixedly mounted on the outer wall of the lower barrel section 3 to support and position the entire barrel body.

[0039] The upper barrel section 1 is further covered by a barrel cover 4, and the barrel cover 4 is provided with an oil return pipe 41 and an oil extraction pipe 42. The opposite sides of the inner wall surface of the upper barrel section 1 are respectively provided with buckles 11, and the buckles 11 are provided with guide grooves 111 extending along the axial direction of the upper barrel section 1. The connecting position of the horizontal plate section 52 and the vertical plate section 51 of the L-shaped partition plate 5 is provided with an avoiding hole 521 avoiding the buckles 11. In use, the two sides of the vertical plate section 51 of the L-shaped partition plate 5 are respectively inserted into the corresponding guide grooves 111, and at this time, the buckles 11 pass through the avoiding hole 521, so that the L-shaped partition plate 5 is smoothly inserted into the upper barrel section 1. At the same time, the horizontal plate section 52 is a semicircular plate, and the diameter of the horizontal plate section 52 is the same as the inner diameter of the upper barrel section 1, so that when the horizontal plate section 52 contacts the conical barrel section 2, the horizontal plate section 52 is stopped from moving downward, and the position of the L-shaped partition plate 5 is locked. The length of the vertical plate section 51 is the same as the length of the upper barrel section 1, so that the L-shaped partition plate 5 can be taken out without contacting the barrel cover 4. The oil extraction cavity formed between the L-shaped partition plate 5 and the barrel wall of the upper barrel section 1 provides a special installation space for the oil extraction pipe 42, and effectively avoids the pollution of the ink during the extraction process. At the same time, the design of the oil permeation hole 522 enables the ink to uniformly permeate into the oil extraction cavity, and ensures the continuity and stability of the oil extraction.

[0040] The lower barrel section 3 is provided with a filter vessel 6 capable of receiving the impurities falling from the conical barrel section 2. The filter vessel 6 is in a cylindrical shape, and the inner edge of the vessel mouth of the filter vessel 6 is provided with a chamfer. The chamfer surface is located below the inner wall surface of the conical barrel section 2, and the outer diameter of the filter vessel 6 is the same as the inner diameter of the lower barrel section 3, so as to eliminate the gap between the two and enable the impurities to naturally deposit and smoothly fall into the filter vessel 6. The height of the filter vessel 6 is generally lower than the height of the lower barrel section 3, so that when the impurities deposit at the bottom of the lower barrel section 3, the filter vessel 6 will not be higher than the lower barrel section 3 due to the height difference between the filter vessel 6 and the lower barrel section 3, so that the filter vessel 6 can still receive the impurities falling from the conical barrel section 2.

[0041] In use, the filter vessel 6 is coaxially inserted into the lower barrel section 3 through the lifting handle 62, and then the L-shaped partition plate 5 is inserted into the upper barrel section 1, and then a certain amount of ink is injected coaxially, and finally the barrel cover 4 is covered, the oil return pipe 41 is inserted into the barrel, and the oil extraction pipe 42 is inserted into the oil extraction cavity. After assembly is completed, printing work can be carried out. A through hole is formed in the center of the barrel cover 4, and after a period of time, the filter vessel 6 is slowly taken out from the barrel through the through hole by using the lifting handle 62, and the impurities in the filter vessel 6 are cleaned. Then the filter vessel 6 is put back through the through hole and the through hole is covered. During the whole process, the operation is continuous, and the impurities will not be floated due to the slow action. When the ink barrel runs for a certain period of time, the machine can be stopped for cleaning, and then the printing work can be carried out again.

[0042] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
