Description

Technical Field

[0001] The present invention relates to the technical field of printing equipment, and specifically to an inking plastic packaging container for a printing press. Background Art

[0002] An ink cartridge is one of the important consumables of a printer, and is a material used by an inkjet printer to store ink and achieve the output function. Inkjet printers are one of the mainstream products in the current printer market. As an important consumable, the sales volume of ink cartridges is continuously increasing and the market scale is constantly expanding.

[0003] In a Chinese invention patent with the publication number CN111976301A, a comparative document of a colorful ink cartridge is proposed, which specifically proposes that "it includes a fixing device, an ink cartridge is provided on the fixing device, a storage ink cartridge is provided above the ink cartridge, a group of ink delivery mechanisms are arranged in an array between the ink cartridge and the storage ink cartridge, and a group of ink recovery mechanisms are also arranged in an array between the ink cartridge and the storage ink cartridge. Both the storage ink cartridge and the ink cartridge are provided with multiple chambers, and a stirring rod and a heating tube are arranged in the ink cartridge".

[0004] The above comparative document also has the following defects: During daily printing, the ink cartridge is not used up completely at one time. After the ink cartridge is used up, when there is still remaining ink in the ink cartridge, the ink outlet needs to be sealed to prevent the remaining ink inside from drying and coagulating. The inventor found that this was not mentioned in the above comparative document. On this basis, we propose an inking plastic packaging container for a printing press. Summary of the Invention

Specific embodiments

[0026] The following combines the accompanying 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 described embodiments are only some embodiments of the present invention, rather than all embodiments.

[0027] Embodiment 1

[0028] Refer to Figures 1-6, An ink - applying plastic packaging container for a printing press, comprising a cylinder body 1. A push - cover 2 is arranged at the upper end of the cylinder body 1. A rotating shaft 3 is arranged at the center of the push - cover 2. A stirring fan blade 4 is arranged at the bottom of the rotating shaft 3. A cavity 5 communicating with the cylinder body 1 is arranged at the lower end of the cylinder body 1. A spherical body 6 is arranged at the lower end of the cavity 5. A telescopic sleeve 7 is clamped on the outer surface of the cavity 5. A through - hole 8 at the lower end of the telescopic sleeve 7 is matched with the spherical body 6. A plurality of truncating components 9 are arranged at the upper end of the cross - section of the through - hole 8, and a plurality of scraping - flat components 10 are arranged at the lower end of the cross - section of the through - hole 8. Both the truncating components 9 and the scraping - flat components 10 are used for cleaning the ink at the connection between the through - hole 8 and the spherical body 6.

[0029] Refer to Figure 4 , The truncating component 9 includes a rack a91, a gear 92 meshing with the rack a91, a rack b93 arranged below the gear 92 and meshing with the gear 92, and an arc - shaped stop block 94 arranged at the front end of the rack b93.

[0030] It is worth mentioning here that during the upward movement of the telescopic sleeve 7, the spherical body 6 presses the rack a91, the rack a91 drives the gear 92 to rotate, and then drives the rack b93 to move in the opposite direction.

[0031] Refer to Figures 4-6 , The inner arc of the arc - shaped stop block 94 is consistent with the arc of the spherical body 6.

[0032] In this embodiment, since the arc of the arc - shaped stop block 94 is consistent with the arc of the spherical body 6, the arc - shaped stop block 94 can closely adhere to the spherical body to block and intercept the flowing - down ink.

[0033] Refer to Figure 6 , The scraping - flat component 10 includes a plurality of rectangular grooves 101 arranged on the inner wall of the through - hole 8, cylinders 102 arranged in the rectangular grooves 101, and scraping plates 103 rotatably arranged on the cylinders 102.

[0034] It is worth mentioning here that since the scraping plates 103 are rotatably arranged on the cylinders 102, during the upward movement of the telescopic sleeve 7, the scraping plates 103 can scrape and clean the ink on the spherical body 6.

[0035] Refer to Figure 6 , The outer side of the scraping plate 103 is arc - shaped, the arc of the scraping plate 103 is consistent with the arc of the spherical body 6, and the scraping plate 103 is arranged in an inclined plane.

[0036] In this embodiment, due to the inclined - plane arrangement of the scraping plates 103, during the extrusion process, the scraping plates 103 clean the ink in the same direction, avoiding inconsistent scraping directions of the scraping plates 103.

[0037] Refer to Figure 2, an external thread 31 is provided on the rotating shaft 3, and the external thread 31 meshes with the internal thread passing through the middle of the push cover 2.

[0038] It is worth mentioning here that through the meshing of the external thread 31 and the internal thread, during the process of the push cover 2 being squeezed downward, the push cover 2 can drive the stirring fan blade 4 to stir inside the ink, improving the uniformity of the ink.

[0039] Refer to Figure 3 , a circle of protrusions 71 is provided on the inner wall of the telescopic sleeve 7, and a circle of grooves 51 is provided on the outer surface of the cavity 5, and the grooves 51 cooperate with the protrusions 71.

[0040] In this embodiment, through the mutual cooperation of the grooves 51 and the protrusions 71, the upper end of the telescopic sleeve 7 can be fixedly arranged on the outer wall of the cavity 5, avoiding the displacement of the telescopic sleeve 7 during use.

[0041] The scraping plate 103 is made of soft silicone.

[0042] The working process is as follows:

[0043] By squeezing the push cover 2, the push cover 2 moves inside the cylinder body 1 and squeezes the ink towards the outlet direction. Through the meshing of the middle of the push cover 2 and the external thread 31 on the rotating shaft 3, the rotating shaft 3 drives its stirring fan blade 4 to rotate inside the cylinder body 1.

[0044] When terminating the ink printing midway, by squeezing the telescopic cover 7, the telescopic cover 7 is closely attached to the spherical body 6. During the rising process of the telescopic sleeve 7, the spherical body 6 squeezes the rack a91, the rack a91 drives the gear 92 to rotate, and then drives the rack b93 to move in the opposite direction. Since the arc-shaped block 94 is consistent with the radian of the spherical body 6, the arc-shaped block 94 can closely adhere to the spherical body to block and intercept the flowing-down ink; since the scraping plate 103 is rotatably arranged on the column body 102, during the rising process of the telescopic sleeve 7, the scraping plate 103 can scrape and clean the ink on the spherical body 6.

[0045] Of course, in this technical solution, those skilled in the art should understand that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of one element can be one, while in other embodiments, the number of this element can be multiple. The term "one" cannot be understood as a limitation on the number.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
