Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a printing machine capable of preventing ink leakage. Background Art

[0002] At present, the printing presses on the market often have ink leakage problems during use, which not only affects the printing quality, but also may cause damage to the machine and even pose a safety hazard. Therefore, designing a printing press that can effectively prevent ink leakage is of great significance for improving printing efficiency and protecting equipment safety.

[0003] The patent with publication number CN216330863U currently discloses an ink printing machine, which is connected to the base through two brackets, the printing roller is connected to the two brackets, the auxiliary roller is connected to the two brackets, the ink box is connected to the two brackets, the motor is connected to the bracket, the rotating shaft is connected to the output end of the motor, the inner rings of the two bearings are fixedly connected to the rotating shaft, the outer rings of the two bearings are fixedly connected to the ink box, the sealing plate is connected to the rotating shaft, and the smear sponge is connected to the ink box. The motor drives the rotating shaft to drive the sealing plate to rotate toward the smear sponge, so that the ink flows from the gap between the sealing plate and the ink box to the smear sponge. The larger the rotation angle of the sealing plate, the larger the gap between the sealing plate and the ink box, and the faster the ink outflow speed, which solves the problem that the ink printing machine cannot control the ink outflow speed from the ink box, thereby affecting the uniformity of ink smearing.

[0004] However, the above technology still has the following problems:

[0005] Adding too much ink to the ink cartridge of a printing press will cause the gas pressure inside the ink cartridge to increase, which may cause the gas pressure regulator to malfunction, resulting in internal pressure greater than the ambient atmospheric pressure, which may cause ink to be ejected from the print head and ink leakage, resulting in poor printing results or product contamination. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a printing machine capable of preventing ink leakage. Through the combined action of a height display component and a cleaning component, the amount of ink inside the ink cartridge can be easily observed, thereby avoiding leakage caused by adding too much ink.

[0007] The utility model provides the following technical solution: a printing machine capable of preventing ink leakage, comprising a printing machine main body, an ink cartridge being highly connected above the printing machine main body, the ink cartridge comprising a cartridge body and an ink injection port connected to the upper end of the cartridge body, characterized in that a rectangular groove is provided on the cartridge body surface, a circular hole is provided on the left side of the rectangular groove, a height display component matching the rectangular groove is fixedly connected in the rectangular groove, and a cleaning component is rotatably connected in the circular hole.

[0008] Furthermore, the length of the rectangular groove is the same as the distance between the upper and lower inner walls of the ink cartridge.

[0009] Furthermore, the height display group includes a transparent PC plate fixed on the rectangular groove, and a scale is engraved on the surface of the transparent PC plate.

[0010] Furthermore, the cleaning assembly includes a rotating shaft arranged in the circular hole, the front end of the rotating shaft is fixedly connected to the first turntable, the rear end of the rotating shaft is fixedly connected to the second turntable, the lower end of the second turntable is fixedly connected to a connecting rod, and the inner surface of the connecting rod is fixedly connected to a rubber strip.

[0011] Furthermore, the width of the rubber strip is slightly longer than the distance from the connecting rod to the inner wall of the ink cartridge.

[0012] Furthermore, a rubber sealing ring is connected to the surface of the rotating shaft.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] This type of printing machine that can prevent ink leakage can directly understand the amount of ink added by observing the capacity value of the ink on the scale on the ink height display component when adding ink to the ink cartridge. At the same time, the rubber strip of the cleaning component can be used to clean the ink remaining on the transparent PC board to ensure that the transparent PC board is always transparent and does not affect the use. At the same time, the scale can also reflect the amount of ink inside the ink cartridge, so that ink can be added to the ink cartridge in time to avoid insufficient ink and affect the printing progress.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 4 A printing machine capable of preventing ink leakage comprises a printing machine main body 1, an ink cartridge 2 is connected at a height above the printing machine main body 1, the ink cartridge 2 comprises a cartridge body and an ink injection port connected to the upper end of the cartridge body, a rectangular groove 3 is provided on the cartridge body surface of the ink cartridge 2, a circular hole 4 is provided on the left side of the rectangular groove 3, a height display component 5 matching the rectangular groove 3 is fixedly connected in the rectangular groove 3, and a cleaning component 6 is rotatably connected in the circular hole 4.

[0022] The printing machine capable of preventing ink leakage in the utility model is similar to the existing ink printing machine structure, such as the patent with publication number CN216330863U discloses an ink printing machine. The main improvement of the utility model is that the ink amount inside the ink box 2 is observed through the joint action of the height display component 5 and the cleaning component 6 to prevent the ink in the ink box 2 from being added too much, causing leakage, or the ink in the ink box 2 is too little, affecting the progress of printing, such as Figures 1 to 4 As shown, when the printing machine capable of preventing ink leakage in the utility model is in use, the staff first rotates the first turntable 602, and by rotating the first turntable 602, the second turntable 603 is driven to rotate by the shaft 601. Since the connecting rod 604 is fixedly connected to the bottom of the second turntable 603, the rubber strip 605 is fixed to the inner surface of the connecting rod 604, so that the rubber strip 605 rotates around the shaft 601. During the rotation process, the rubber strip 605 is always tightly fitted with the inner wall of the ink cartridge 2, so that when the rubber strip 605 passes through the transparent PC plate 501, the ink remaining on the transparent PC plate 501 can be cleaned, thereby ensuring the transparency of the transparent PC plate 501, making it easy to observe the inside of the ink cartridge 2, thereby avoiding excessive ink addition and causing leakage.

[0023] like Figure 2 As shown, the length of the rectangular groove 3 is the same as the distance between the upper and lower inner walls of the ink cartridge 2 .

[0024] Specifically, the height of the rectangular groove 3 determines the size of the transparent PC board 501 , making it easy to observe the actual height of the ink in the ink cartridge 2 .

[0025] like Figure 1 or Figure 2 As shown, the height display component 5 includes a transparent PC plate 501 fixed on the rectangular groove 3, and a scale 502 is engraved on the surface of the transparent PC plate 501.

[0026] Specifically, the transparent PC sheet 501 can be used to observe the actual height of the ink in the ink cartridge 2, and the capacity value of the scale 502 can be used to observe the remaining amount of ink in the ink cartridge 2 to prevent the printing from being stopped due to insufficient ink, thereby affecting the progress of printing. At the same time, the amount of ink added to the ink cartridge 2 can also be observed in real time to avoid adding too much ink, which may cause ink leakage in the ink cartridge 2.

[0027] like Figure 3 or Figure 4 As shown, the cleaning assembly 6 includes a rotating shaft 601 arranged in the circular hole 4, the front end of the rotating shaft 601 is fixedly connected to the first turntable 602, the rear end of the rotating shaft 601 is fixedly connected to the second turntable 603, the lower end of the second turntable 603 is fixedly connected to a connecting rod 604, and the inner surface of the connecting rod 604 is fixedly connected to a rubber strip 605.

[0028] Specifically, the shaft 601 drives the second turntable 603 to rotate. Since the connecting rod 604 is fixedly connected to the bottom of the second turntable 603, the rubber strip 605 is fixed to the inner surface of the connecting rod 604, so that the rubber strip 605 rotates around the shaft 601. During the rotation process, the rubber strip 605 can clean the ink remaining on the transparent PC board 501 when passing through the transparent PC board 501, thereby ensuring the transparency of the transparent PC board 501 and facilitating the observation of the amount of ink in the ink cartridge 2.

[0029] like Figure 3 As shown, the width of the rubber strip 605 is slightly longer than the distance from the connecting rod 604 to the inner wall of the ink cartridge 2 .

[0030] Specifically, the width of the rubber strip 605 is slightly longer than the distance from the connecting rod 604 to the inner wall of the ink cartridge 2 , in order to ensure that the rubber strip 605 always fits tightly against the inner wall of the ink cartridge 2 , thereby enhancing the cleaning effect of the rubber strip 605 on the transparent PC board 501 .

[0031] like Figure 4 As shown, the surface of the rotating shaft 601 is connected with a rubber sealing ring 7

[0032] Specifically, the rubber sealing ring 7 ensures the airtightness of the ink cartridge 2 to prevent the airtightness inside the ink cartridge 2 from being damaged, thereby preventing ink from leaking from the circular hole 4 of the ink cartridge 2 .

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
