Description

Technical Field

[0001] This utility model relates to the field of aluminum foil packaging film production technology, and in particular to an aluminum foil packaging film printing device. Background Technology

[0002] After aluminum foil packaging film is produced, some products need to be printed on the surface for aesthetic purposes. The two most common methods are roller printing and coating printing. Roller printing can continuously print on the packaging film roll without interruption, while coating printing requires intermittent shutdowns to achieve the printing effect. Therefore, roller printing is often used. However, the printing roller has a fixed specification and can only print on one type of packaging film. When printing on different specifications of packaging film, the printing roller needs to be changed. However, the printing roller replacement in the current technology is difficult and not easy to operate, which affects production efficiency. Utility Model Content

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 4 It is known that an aluminum foil packaging film printing device includes a machine body 1, on which a printing mechanism is detachably installed. The printing mechanism includes a printing roller 2 and a pressure roller 3 that rotate in opposite directions. Multiple guide rollers 4 are provided inside the machine body 1. A coating roller 5 that contacts the printing roller 2 is provided inside the machine body 1. A material pool 6 is provided at the bottom of the machine body 1. The material pool 6 contains dye. The dye is transported to the coating roller 5 through a pipe 7. An outlet 8 is provided at the right end of the machine body 1. A dryer 9 is provided inside the outlet 8.

[0018] In practical use, this utility model

[0019] The aluminum foil packaging film roll is passed sequentially between the guide roller 4, the printing roller 2 and the pressure roller 3, and pulled out from the outlet 8. The equipment is started, and the dye is transported from the material pool 6 to the coating roller 5. Then the coating roller 5 transfers the dye to the printing roller 2. The aluminum foil packaging film passes between the printing roller 2 and the pressure roller 3 to realize the printing process of the aluminum foil packaging film. Then the printed side is dried by the dryer 9 and discharged from the outlet 8.

[0020] To facilitate the replacement of the printing roller 2, a slot is provided on the top of the machine body 1. The printing mechanism includes a housing 10 that cooperates with the slot. The ends of the printing roller 2 and the pressure roller 3 are driven by gear 11 to rotate in opposite directions. A first motor 12 that drives the printing roller 2 is provided on the outside of the housing 10. The printing roller 2 and the pressure roller 3 form a printing mechanism. The replacement is carried out synchronously, which can quickly complete the replacement without interfering with other parts, improve the replacement speed, and not affect the production progress.

[0021] A groove 13 is provided on the side of the machine body 1. A slider 14 is rotatably mounted on the end of the coating roller 5 and slides within the groove 13. An adjusting rod 15 is threaded onto the machine body 1 and rotatably connected to the slider 14. The adjusting rod 15 is used to adjust the position of the coating roller 5. A second motor 16 for driving the coating roller 5 is provided on the outside of the slider 14. When changing the printing mechanism, rotating the adjusting rod 15 moves the coating roller 5 away from the printing roller 2 to avoid interference, thereby quickly completing the replacement of the printing roller 2.

[0022] An extension plate 17 is provided at the edge of the material pool 6. The extension plate 17 extends beyond the connection between the printing roller 2 and the pressure roller 3 to collect the dripping dye and return it to the material pool 6 for recycling.

[0023] The material tank 6 is equipped with a material pump 18 connected to the pipe 7, which is used to deliver the dye to the coating roller 5.

[0024] The machine body 1 is equipped with a fixing rod 19, and a scraper 20 with its end in contact with the coating roller 5 is provided on the fixing rod 19. Multiple springs 21 are provided between the scraper 20 and the fixing rod 19. The scraper 20 is used to scrape the dye on the coating roller 5 evenly, so that it is evenly and neatly transferred to the printing roller 2. This ensures the printing quality when printing aluminum foil packaging film. When the position of the coating roller 5 changes due to the replacement of printing roller 2 of different specifications, the scraper 20 can always be in contact with the coating roller 5 due to the action of the springs 21, ensuring the scraping effect.

[0025] Compared with the prior art, this utility model has the following advantages: it allows for the simultaneous replacement of the printing roller and the pressure roller, and the replacement of the printing roller can be completed quickly without interfering with other components, thus shortening downtime and accelerating production.
