A gravure printing machine for packaging film processing

Abstract

This utility model proposes a gravure printing machine for packaging film processing, including a printing machine body, a printing component, a fixing and limiting component, an ink scraping component, an ink storage component, an ink flow component, and an adjustment component. This utility model utilizes the coordinated operation of the fixing and limiting components. An upper and lower fixing plate limit and fix the scraper, and a rotating threaded column moves a fixing pressure plate downwards, thereby fixing the top of the upper fixing plate. This double fixing of the scraper effectively prevents it from loosening, thus preventing printing quality problems. Furthermore, the ink flow component agitates the ink in the ink tank, ensuring uniform ink mixing and guaranteeing ink quality, thereby ensuring the printing quality of the packaging film.

Description

Technical Field

[0001] This utility model relates to the field of packaging film printing technology, and in particular to a gravure printing machine for packaging film processing. Background Technology

[0002] Patent document CN222538524U discloses a doctor blade clamp for gravure printing machines, belonging to the field of doctor blade installation technology, which solves the problem of poor clamping effect of existing doctor blade clamps. This doctor blade clamp includes a mounting base plate, a clamping plate on top of the mounting base plate, and multiple locking bolts between the clamping plate and the mounting base plate. The upper surface of the mounting base plate has a mounting groove for placing the doctor blade, and the lower part of the mounting base plate has a positioning plate for limiting its position. A fine-tuning device for adjusting the pressure of the doctor blade on the roller is provided on one side of the mounting base plate and the clamping plate. An ink collection device is provided on the mounting base plate and the positioning plate. This gravure printing machine doctor blade clamp effectively clamps the doctor blade, improving the doctor blade effect while facilitating installation and disassembly, and is characterized by its ease of use and high practicality.

[0003] However, the clamping mechanism does not securely hold the doctor blade, causing it to loosen and affecting printing quality. Furthermore, existing ink may settle in the ink tank, resulting in inconsistent ink quality across different areas and impacting overall print quality. Therefore, it is necessary to improve this structure to overcome these shortcomings. Utility Model Content

[0049] Example 2

[0050] like Figure 1-4 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the ink flow assembly includes a rotary motor 510 and a stirring roller 520. The rotary motor is disposed in the printing press body, with its rotating end facing the printing press body.

[0054] The working principle of this utility model:

[0055] During operation, the packaging film comes into contact with the printing roller. The rotary motor drives the stirring roller in the ink tank to rotate, which stirs the ink in the ink tank while rotating. At the same time, the stirring column on the stirring roller breaks up air bubbles in the ink. The bottom of the printing roller comes into contact with the ink in the ink tank. The doctor blade is placed in the limiting groove of the lower fixed plate, and then the liner is placed on top of the doctor blade. The upper fixed plate is placed on top of the liner. At the same time, the fixing bolts are inserted into the upper fixed plate, the liner, the doctor blade, and the lower fixed plate in sequence to fix the doctor blade. Then, the threaded column on the fixed bracket is rotated. The threaded column drives the fixed pressure plate to move downward through the threaded engagement, thereby fixing the upper fixed plate again. Then, the adjusting screw is rotated. The adjusting screw drives the lower fixed plate to move through the threaded engagement, thereby adjusting the distance between the doctor blade and the printing roller. This allows the doctor blade to scrape off the ink on the printing roller, so that the printing roller can print on the packaging film.
