Description

Technical Field

[0001] The utility model relates to the technical field of flexible printing machines, in particular to a flexible printing machine for PP environmental protection labels. Background Art

[0002] Flexographic printing press uses a flexible printing plate and transfers ink through an anilox roller for printing. It is a type of letterpress printing process, referred to as flexographic printing. During printing, the anilox roller evenly applies a certain thickness of ink layer on the image part of the printing plate, and then under the action of the pressure of the impression roller, the ink layer of the image part is transferred to the surface of the substrate, forming a clear image.

[0003] During the production process, the environmental protection label needs to be printed by a flexible printing machine. During the printing process, the excess ink on the outer wall of the anilox roller needs to be scraped off by a doctor blade. However, the existing doctor blade is generally fixed and cannot be debugged during use. The anilox roller may be more or less inked. In view of this, we need a flexible printing machine for PP environmental protection labels. Utility Model Content

[0004] The purpose of the present utility model is to provide a flexible printing machine for PP environmental protection labels to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a flexible printing machine for PP eco-friendly labels, comprising a machine body, an ink tank being provided on the machine body, an anilox roller being rotatably connected to the inner wall of the machine body, a printing plate roller being rotatably connected to the inner wall of the machine body, a pressure roller being rotatably connected to the inner wall of the machine body, and a winding roller being rotatably connected to the inner wall of the machine body, an adjusting mechanism being provided inside the ink tank, a stopping mechanism being provided on the wall of the adjusting mechanism, and the adjusting mechanism comprising:

[0006] A slide plate, the slide plate being slidably connected to the inner wall of the ink tank;

[0008] The ink scraper is fixedly installed on the end of the extrusion rod, and the bottom wall of the ink scraper is provided with an inclined groove.

[0009] Preferably, a load-bearing spring is sleeved on the outer wall of the extrusion rod, one end of the load-bearing spring is fixedly connected to the outer wall of the extrusion rod, and the other end of the load-bearing spring is fixedly connected to the outer wall of the slide plate.

[0010] Preferably, a threaded rod is rotatably connected to the outer wall of the slide, the threaded rod passes through the interior of the body, the inner wall of the body is threadedly connected to the threaded rod, and a turntable is fixedly installed on the end of the threaded rod.

[0011] Preferably, the braking mechanism includes a rotating rod, which is rotatably connected to the inner wall of the slide.

[0012] Preferably, a torsion spring is sleeved on the outer wall of the rotating rod, one end of the torsion spring is fixedly connected to the outer wall of the rotating rod, and the other end of the torsion spring is fixedly connected to the inner wall of the slide plate.

[0013] Preferably, a curved rod is fixedly passed through the interior of the rotating rod, one end of the curved rod is located on the side of the ink scraper, and a rubber block is fixedly mounted on the other end of the curved rod.

[0014] Compared with the existing technology, the utility model provides a flexible printing machine for PP environmental protection labels, which has the following beneficial effects:

[0015] 1. The PP eco-friendly label flexible printing machine can adjust the position of the scraper at the end of the extrusion rod through the slide in the adjustment mechanism, which makes it convenient for the scraper to scrape off the excess ink on the outer wall of the anilox roller. At the same time, the inclined groove on the bottom wall of the scraper can make the scraped ink flow down to prevent it from affecting the subsequent scraping of ink by the scraper.

[0016] 2. The PP eco-friendly label flexible printing machine uses the upper end of the curved rod in the stop mechanism to be squeezed by the ink scraper, which can drive the rubber block at the bottom end of the curved rod to move downward to squeeze the inner wall of the ink tank. The increased friction force can prevent the slide from moving to the right, preventing the ink scraper from excessively squeezing the outer wall of the anilox roller, resulting in too little ink on the outer wall of the anilox roller and affecting printing.

[0022] like Figures 1-4As shown, the utility model provides a technical solution: a flexible printing machine for PP environmental labels, including a body 1, an ink tank 2 is opened on the body 1, a screen roller 3 is rotatably connected to the inner wall of the body 1, a printing plate roller 4 is rotatably connected to the inner wall of the body 1, a pressure roller 5 is rotatably connected to the inner wall of the body 1, and a winding roller 6 is rotatably connected to the inner wall of the body 1, an adjusting mechanism 7 is provided inside the ink tank 2, and a stopping mechanism 8 is provided on the wall of the adjusting mechanism 7.

[0023] In this embodiment, an adjustment mechanism 7 is provided inside the ink tank 2. The slide 71 in the adjustment mechanism 7 can drive the position of the scraper 74 at the end of the extrusion rod 72 to adjust, so that the scraper 74 can scrape off the excess ink on the outer wall of the anilox roller 3. At the same time, the inclined groove 75 provided on the bottom wall of the scraper 74 can make the scraped ink flow down, preventing it from affecting the subsequent scraping of ink by the scraper 74.

[0024] In this embodiment, a stopping mechanism 8 is provided on the wall of the adjustment mechanism 7. The upper end of the curved rod 83 in the stopping mechanism 8 is squeezed by the ink scraper 74, so that the curved rod 83 can drive the rubber block 84 at the bottom end to move downward to squeeze the inner wall of the ink tank 2. The friction force is increased so that the slide plate 71 can no longer move to the right, thereby preventing the ink scraper 74 from excessively squeezing the outer wall of the anilox roller 3, resulting in too little ink on the outer wall of the anilox roller 3 to affect printing.

[0025] The above-mentioned adjustment mechanism 7 includes a slide plate 71, which is slidably connected to the inner wall of the ink tank 2. The inner sliding part of the slide plate 71 is penetrated by an extrusion rod 72. The outer wall of the extrusion rod 72 is sleeved with a load spring 73. One end of the load spring 73 is fixedly connected to the outer wall of the extrusion rod 72, and the other end of the load spring 73 is fixedly connected to the outer wall of the slide plate 71. The end of the extrusion rod 72 is fixedly mounted with a scraper 74. The scraper 74 can be moved to the left relative to the slide plate 71 by squeezing. The bottom wall of the scraper 74 is provided with an inclined groove 75. The oblique groove 75 provided on the bottom wall of the ink scraper 74 can allow the scraped ink to flow down smoothly to prevent affecting the subsequent scraping of ink by the ink scraper 74. A threaded rod 76 is rotatably connected to the outer wall of the slide 71. The threaded rod 76 passes through the interior of the body 1. The inner wall of the body 1 is threadedly connected to the threaded rod 76. A turntable 77 is fixedly installed on the end of the threaded rod 76. The turntable 77 drives the threaded rod 76 to rotate, which can drive the end slide 71 to move to the right, so that the position of the ink scraper 74 can be adjusted.

[0026] The above-mentioned braking mechanism 8 includes a rotating rod 81, which is rotatably connected to the inner wall of the slide plate 71, and a torsion spring 82 is sleeved on the outer wall of the rotating rod 81. One end of the torsion spring 82 is fixedly connected to the outer wall of the rotating rod 81, and the other end of the torsion spring 82 is fixedly connected to the inner wall of the slide plate 71. A curved rod 83 is fixedly passed through the interior of the rotating rod 81. When the ink scraper 74 moves to the left, the outer wall squeezes the upper end of the curved rod 83, which can make the curved rod 83 rotate around the rotating rod 81. One end of the curved rod 83 is located at the side of the ink scraper 74, and the other end of the curved rod 83 is fixedly installed with a rubber block 84. The curved rod 83 drives the rubber block 84 at the bottom end to move downward to squeeze the inner wall of the ink tank 2, which can prevent the slide plate 71 from continuing to move to the right and causing the ink scraper 74 to excessively squeeze the outer wall of the anilox roller 3, resulting in too little ink on the outer wall of the anilox roller 3 affecting printing.

[0027] In this embodiment, when the position of the scraper 74 needs to be adjusted, the turntable 77 drives the threaded rod 76 to rotate, thereby causing the threaded rod 76 to drive the end slide 71 to move to the right, thereby causing the slide 71 to drive the scraper 74 at the end of the extrusion rod 72 to move to the right and fit the outer wall of the anilox roller 3, thereby causing the scraper 74 to move to the left relative to the slide 71 through extrusion. When the scraper 74 moves to the left, the outer wall squeezes the upper end of the bent rod 83, thereby causing the bent rod 83 to rotate around the rotating rod 81, causing the bent rod 83 to drive the bottom end The rubber block 84 moves downward to squeeze the inner wall of the ink tank 2, and then the friction force is increased so that the slide plate 71 can no longer move to the right, preventing the slide plate 71 from continuing to move to the right, causing the scraper 74 to excessively squeeze the outer wall of the anilox roller 3, resulting in too little ink on the outer wall of the anilox roller 3 affecting printing. After the adjustment is completed, the anilox roller 3 applies ink to the printing plate roller 4, and then the printing plate roller 4 completes the printing of the label when the pressure roller 5 squeezes the label, and finally the printed note is wound up by the winding roller 6, thereby completing the label printing process.

[0028] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
