Description

Technical Field

[0001] This utility model relates to the field of plastic flexible packaging printing technology, specifically to an ink splash prevention device for plastic flexible packaging printing. Background Technology

[0002] Currently, the plastic flexible packaging industry is developing rapidly. Due to its advantages such as being lightweight, foldable, waterproof, moisture-proof, low-cost, and widely applicable, plastic flexible packaging has been widely used in modern life. However, the ink tanks of existing plastic flexible packaging printing machines are generally open, and the cylindrical roller printing plate directly contacts the ink in the ink tank. During the printing process, the roller rotates at a relatively high speed, which can cause ink to splash out, resulting in material waste. Therefore, this utility model proposes an ink splash prevention device for plastic flexible packaging printing to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an ink splash prevention device for printing on plastic flexible packaging, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an ink splash prevention device for printing on plastic flexible packaging, comprising...

[0005] The machine base has an ink tank mounted on its top. A fixing block is fixedly installed on the top of the ink tank. A printing plate roller is slidably connected to the side of the fixing block. An impression roller is slidably connected to the top of the printing plate roller.

[0006] Preferably, a sleeve is fixedly installed on the side of the fixing block, a rotating shaft is fixedly connected to the side of the sleeve, a control motor is fixedly connected to the side of the rotating shaft, a power gear is fixedly installed on the side of the rotating shaft, and a connecting rod is meshed with the side of the power gear. A scraper is slidably connected to the end of the connecting rod away from the power gear.

[0007] Preferably, the side of the fixing block is provided with a groove, and a scraper is slidably connected to the inner side of the groove. The scraper is provided with a rubber cotton design on its side, and the top of the ink tank is provided with a return groove.

[0008] Preferably, a splash guard is fixedly installed on the side of the ink tank, and a splash guard side plate is fixedly installed on the top of the ink tank, with the splash guard side plate sleeved on the side of the printing plate roller.

[0009] Preferably, both the splash guard and the splash guard side plate are made of soft plastic, and the top of the splash guard side plate is fixedly connected to the splash guard, and the length of the return channel is equal to that of the splash guard.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, by setting the anti-splash plate and anti-splash side plate structure around the printing plate roller, the printing plate roller can be pushed out of the ink tank to one side. Due to the rapid rotation, the ink thrown out is blocked, and the ink is guided from the anti-splash plate and side plate to the return groove at the top of the ink tank, preventing ink from being thrown out and causing pollution, and reducing material waste. Furthermore, by using a control motor to drive the connecting rod and scraper to move in the slide groove set in the fixed block, the rubber cotton design of the scraper can not only adhere to the inner side of the anti-splash plate, but also not only hang the splashed ink and guide it to the return groove to prevent the splashed ink from solidifying, but also clean the inner side of the anti-splash plate, increasing the service life and reducing the work of cleaning the anti-splash plate.

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Please see Figures 1 to 3 This utility model provides a technical solution: an ink splash prevention device for printing on plastic flexible packaging, comprising...

[0017] The machine base 1 has an ink tank 2 mounted on its top. A fixing block 3 is fixedly installed on the top of the ink tank 2. A printing plate roller 4 is slidably connected to the side of the fixing block 3. An impression roller 5 is slidably connected to the top of the printing plate roller 4.

[0018] A sleeve 6 is fixedly installed on the side of the fixed block 3. A rotating shaft 7 is fixedly connected to the side of the sleeve 6. A control motor 8 is fixedly connected to the side of the rotating shaft 7. A power gear 9 is fixedly installed on the side of the rotating shaft 7. A connecting rod 10 is meshed with the side of the power gear 9. A scraper 11 is slidably connected to the end of the connecting rod 10 away from the power gear 9. The control motor 8 can drive the scraper 11 to move back and forth through the connecting rod 10, so as to clean the inside of the anti-splash plate 13 multiple times and scrape the splashed ink into the return groove 12.

[0019] The side of the fixed block 3 is provided with a sliding groove, and the inner side of the sliding groove is slidably connected to a scraper 11. The side of the scraper 11 is provided with a rubber cotton design. The top of the ink tank 2 is provided with a return groove 12, which is also provided with a rubber cotton design. It is in a curved fit with the inner side of the splash plate. During the process of being at the top and bottom, the rubber cotton is in a compressed state to squeeze out the ink. When the rubber cotton is in the middle position, it is in a relaxed state and can absorb the ink. During this process, it can not only clean up the splashed ink, but also clean the splash plate 13.

[0020] A splash guard 13 is fixedly installed on the side of the ink tank 2, and a splash guard 14 is fixedly installed on the top of the ink tank 2. The splash guard 14 is sleeved on the side of the printing plate roller 4. Both the splash guard 13 and the splash guard 14 are made of soft plastic. The top of the splash guard 14 is fixedly connected to the fixing block 3. The length of the return groove 12 is equal to that of the splash guard 13.

[0021] In practical use: First, insert the plastic flexible packaging into the printing plate roller 4 and the impression roller 5. At this time, the printing plate roller 4 and the impression roller rotate synchronously. During the rotation of the printing plate roller 4, ink will be carried out from the ink tank 2, so that the ink is printed onto the plastic packaging. The ink splashed out by the printing plate roller 4 during rapid rotation is blocked by the splash plate 13 and the splash plate 14, and the ink is guided from the splash plate 13 and the side plate to the return groove 12 at the top of the ink tank 2, preventing ink from splashing out and contaminating the packaging. To reduce material waste, during the printing process, the control motor 8 is started, which drives the power gear 9 to rotate. The power gear 9 drives the connecting rod 10 to move in the slide groove set in the fixed block 3. At the same time, the connecting rod 10 drives the scraper 11 to move. The scraper 11 is also designed with rubber cotton, which fits against the inside of the anti-splash plate 13. This not only hangs the splashed ink down and guides it into the return tank 12 to prevent the splashed ink from solidifying, but also cleans the inside of the anti-splash plate 13, increases the service life, and reduces the work of cleaning the anti-splash plate 13.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
