Description

Technical Field

[0001] The utility model relates to the technical field of gravure printing machine parts, in particular to an ink tank component of a gravure printing machine capable of eliminating bubbles. Background Art

[0002] The ink tank of the gravure printing machine is usually equipped with a scraper. The function of the scraper is to scrape off the excess ink on the surface of the printing roller soaked with ink, leaving only the ink in the concave grooves and then being pressed onto the substrate. If the excess ink on the printing surface is not scraped off, the printed image will not be clear. The ink tank can store the ink.

[0003] For example, the patent document with publication number CN214354802U discloses an ink tank for a gravure printing machine. During use, the device transforms the original ink tank, adds a tray between the printing plate and the original ink tank, reduces the amount of ink carried away by the high-speed operation of the printing plate, and at the same time increases a portion of the ink return space that is not affected by the rotation of the printing plate. Excess ink will flow back to the ink return channel and will not overflow in large quantities, ensuring that the ink can flow back and be replenished in time, so that the ink supply is sufficient, thereby improving printing quality and production efficiency.

[0004] In the above, the outside of the ink tank is equipped with an additional device, and then the excess ink can be recovered. During the rotation of the printing roller, the ink inside will bubble to a certain extent. If the bubbles are not eliminated, the printing quality will be affected during the printing process. In view of the above situation, a gravure printing machine ink tank component that can eliminate bubbles is now provided. Utility Model Content

[0007] The fixed connection block can be fixed to the top wall of the ink tank body by screws, and the air holes can disperse the agitated air to achieve a uniform effect.

[0008] Furthermore, the blowing assembly includes a motor and fan blades, and the bottom of the motor is connected to the fan blades.

[0009] Furthermore, blocks are provided on both the left and right sides of the inner bottom of the ink tank body, and the top of the block is connected to a flow blocking component.

[0010] Furthermore, the baffle assembly comprises a sliding block, a baffle plate and a rubber block. The inner side of the sliding block is connected to the baffle plate, and the upper and lower ends of the baffle plate are connected to the rubber blocks.

[0011] The spoiler is connected and fixedly supported by a rubber block to improve stability, and the sliding block and the clamping block are clamped and fixed.

[0012] Furthermore, a fixing plate is connected to the inner right wall of the ink tank body, and a scraping assembly is connected to the left side of the fixing plate.

[0013] Furthermore, the scraping assembly includes a moving block, a scraper and a tension spring, the left side of the moving block is connected to the scraper, and the bottom end of the scraper is connected to the tension spring.

[0014] The scraper is connected to the moving block and the tension spring to contact the roller of the roller frame to scrape and remove excess ink.

[0015] Furthermore, a roller frame is arranged at the middle of the inner bottom end of the ink tank body, and a drainage component is arranged at the bottom end of the ink tank body.

[0016] Furthermore, the discharge assembly includes an ink discharge tube and a rotating plug, and the interior of the ink discharge tube is connected to the rotating plug.

[0017] The hole is set inside the rotating plug to open and block the ink discharge pipe.

[0018] Compared with the prior art, the beneficial effects of the utility model are: by setting a connection between the drying component and the blowing component, the surface bubbles are destroyed by hot air to avoid affecting the subsequent printing use, the inner baffle component limits the rotation rate, and reduces the generation of bubbles to a certain extent. The scraping component on the right cooperates with the roller frame to scrape, which can scrape away excess ink and avoid a large amount of ink affecting the subsequent product quality.

[0019] 1. During use of the utility model, the connecting block is fixed with screws, and then the card frame is fixed to the inner top of the ink tank body. At this time, the motor drives the fan blades to rotate and blow air, and the air holes can divert the wind and disperse it. Then the wind passes through the drying net at the bottom and becomes hot air, which can blow and break the bubbles on the surface of the ink. This setting can be used for defoaming treatment to avoid affecting the subsequent product printing quality.

[0020] 2. During use of the utility model, the inner sliding block is fixedly connected with the clamping block, and then the baffle is blocked on the inside, which slows down the movement speed of the ink on the inside, reduces the bubble rate, further improves the defoaming efficiency, and improves the practicability of the equipment.
