Description

Technical Field

[0001] This utility model relates to an ink scraping assembly for printing rollers in packaging and decoration printing, belonging to the technical field of packaging and decoration printing equipment. Background Technology

[0002] The printing roller is the "ink carrier" on the packaging printing machine, just like a rolling pin, spreading the ink evenly onto products such as packaging boxes and labels. It is usually a steel or ceramic rod with tiny pits (professionally called cells) that are invisible to the naked eye on its surface. These pits and grooves determine how much ink it can carry.

[0003] Chinese Patent Publication No. CN217778109U discloses an ink scraping assembly for printing rollers in packaging and decoration printing, relating to the field of ink scraping technology for printing rollers. The assembly includes a base with two sets of support frames fixedly mounted on its top. This invention utilizes a fixing mechanism to achieve the following: rotating a handwheel drives a fixing screw to rotate, causing the fixing screw to move along the inner wall of a threaded seat while simultaneously moving a first connecting block, which in turn moves a pressing block. This results in multiple pressing blocks moving synchronously, with their tops pressing against several rotating plates, causing the rotating plates to rotate and quickly fixing the scraper. During disassembly, rotating the handwheel in the opposite direction moves the pressing blocks back to their original positions, releasing them from their limiting pressure on the rotating plates. This allows the scraper to be removed and replaced along the outer wall of the fixed shaft. Through the coordinated use of these components, rapid scraper replacement is achieved.

[0004] The aforementioned patent has the following problems: by pressing and fixing one end of the rotating plate to the top of the scraper, the scraper can be quickly limited and fixed. During disassembly, by rotating the handwheel in the opposite direction, the fixing screw can be rotated in the opposite direction, thereby moving and resetting multiple extrusion blocks. However, there is still a problem with the collection of scraped ink, which means that the ink cannot be collected and processed after scraping, which may increase the difficulty of subsequent cleaning work.

[0005] Therefore, it is urgent to improve the ink scraping assembly for printing rollers to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide an ink scraping assembly for printing rollers of packaging and decoration printing.

Detailed Implementation

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Examples, such as Figures 1-4 As shown, an ink scraping assembly for printing rollers of packaging and decoration printed materials includes a brush roller 2 and a scraper 6 located on one side of the brush roller 2. One side of the scraper 6 is in contact with the surface of the brush roller 2. The scraper 6 is used to scrape off the ink. An ink recovery mechanism is provided on the side of the scraper 6 away from the brush roller 2. By setting the scraper 6 on the device and having one end of the scraper 6 in contact with the brush roller 2, the scraper 6 can be used to scrape off the ink attached to the brush roller 2, thereby avoiding excessive ink accumulation on the brush roller 2, which would increase the difficulty of subsequent cleaning.

[0026] The ink recovery mechanism set at the other end of the scraper 6 can recover the ink scraped off by the scraper 6. This not only solves the problem of how to recover the scraped ink, but also allows the recovered ink to be reused. During this process, the scraper 6 is tilted, which can guide the flow of ink.

[0027] It should be noted that the apparatus described in this application is only a part of the printing equipment, and not the entire printing apparatus.

[0028] The ink recovery mechanism includes a connecting base 5, a storage box 7 slidably disposed within the connecting base 5, and connecting plates 4 fixedly disposed on both sides of the storage box 7. The storage box 7 is located directly below the side of the scraper 6 away from the brush roller 2. The storage box 7 can recover the ink scraped off by the scraper 6. The connecting base 5 is fixed by the two connecting plates 4, which can limit the position of the storage box 7, thereby achieving the above-mentioned ink recovery effect.

[0029] When it is necessary to collect the ink stored in the storage box 7, the staff can slide the storage box 7 away from the connecting base 5, and then pour the ink stored in the storage box 7 into the designated storage location.

[0030] It should be noted that the connecting plate 4 is located on one side of the opposite ends of the connecting base 5, so as not to obstruct the sliding of the storage box 7. At the same time, the size of the connecting base 5 and the storage box 7 can be customized according to the needs of use, rather than the fixed length and width shown in the figure.

[0031] Furthermore, the scraper 6 is fixedly connected to one side of the connecting plate 4 on both sides, and a support plate 1 is fixedly connected to one side of each of the two connecting plates 4. The setting of the connecting plate 4 can fix the position and angle of the scraper 6, so that the scraper 6 can achieve the function required above. At the same time, the connecting plate 4 is fixed to the support plate 1, so that the scraper 6 and the connecting base 5 are installed on the inner side of the support plate 1 for use.

[0032] Furthermore, the brush roller 2 is fixedly provided with rotating rods 9 at both ends. The rotating rods 9 extend into the support plate 1 and are rotatably connected to the inside of the support plate 1. A drive motor 3 is fixedly connected to one side of the support plate 1 through a support plate. The output end of the drive motor 3 extends into the support plate 1 and is fixedly connected to one end of the rotating rod 9. The brush roller 2 can rotate on the inside of the support plate 1 through the rotating rod 9, thereby allowing the drive motor 3 fixedly provided on the outside of the support plate 1 to rotate.

[0033] Furthermore, a cleaning plate 11 is slidably installed inside the storage box 7. The cleaning plate 11 is used to scrape off the ink on the inner wall of the storage box 7. A slider 12 is fixedly installed on one side of the cleaning plate 11, and a guide groove 13 is opened on the upper half of one side of the storage box 7 for guiding the cleaning plate 11 to slide. The slider 12 is slidably connected to the guide groove 13. When the ink stored in the storage box 7 is poured out, the staff can pull the cleaning plate 11 to scrape the inside of the storage box 7, so that the ink attached to the inside of the storage box 7 can be scraped off. In this way, when pouring out the ink inside the storage box 7, the staff can conveniently use the cleaning plate 11 to clean the inside of the storage box 7. This can avoid the increased cleaning difficulty caused by a large amount of ink adhering to the inner wall of the storage box 7 after long-term use.

[0034] The slider 12 provided on one side of the cleaning plate 11 can slide with the storage box 7 through the guide groove 13, thereby guiding and restricting the sliding of the cleaning plate 11.

[0035] Furthermore, a buckle 10 is fixedly provided at the end of the storage box 7 away from the handle, and a snap-fit ​​groove 14 is provided at the end of the connecting base 5 away from the opening to engage with the buckle 10. The storage box 7 can be connected to the snap-fit ​​groove 14 on the inner wall of the connecting base 5 through the buckle 10 fixed at one end. Thus, after the storage box 7 slides inside the connecting base 5, the storage box 7 can be slidably fixed to the connecting base 5 through the snap-fit ​​groove 14 and the buckle 10.

[0036] It should be noted that the slot on the buckle 10 can be engaged with the locking rod fixed inside the locking slot 14, so that the two can be engaged and connected.

[0037] In this embodiment, as Figures 1-4 As shown in this embodiment, the principle of the ink scraping assembly for the printing roller of a packaging and decoration printing product is as follows:

[0038] By setting a scraper 6 on the device, and having one end of the scraper 6 in contact with the brush roller 2, the scraper 6 can be used to scrape off the ink adhering to the brush roller 2, thereby avoiding excessive ink accumulation on the brush roller 2 and increasing the difficulty of subsequent cleaning.

[0039] The ink recovery mechanism set at the other end of the scraper 6 can recover the ink scraped off by the scraper 6. This not only solves the problem of how to recover the scraped ink, but also allows the recovered ink to be reused. During this process, the scraper 6 is tilted, which guides the flow of ink.
