Technical Field
[0001] The utility model specifically relates to the technical field of ink collection and scraping back in screen printing, in particular to a screen printing machine with an ink collection and scraping back structure. Background Art
[0002] A screen printer is a machine that uses a screen printing plate to print, and is a type of printing press. A screen printer is a machine that prints text and images, and is a general term for machines or equipment used to produce printed products. A screen printer is a more representative printing device among stencil printers. In addition to silk, the materials used to make screens can also be nylon wire, copper wire, steel wire, or stainless steel wire.
[0003] At present, when the traditional screen printing device is working, the pattern on the screen printing plate is effectively printed with ink through a scraper. In the printing process, when the scraper is moving, the excess ink will be effectively scraped to one side. After the printing is completed, the excess ink will remain inside the screen printing plate frame. In this way, when the next tooling is printed, the excess ink inside the screen printing plate frame will affect the printing, which may cause uneven printing color. In order to recycle the excess ink, it is necessary to provide an ink collection and scraping structure in the screen printing machine.
[0004] After searching, Chinese patent publication number CN202121155080.X discloses a printing ink recovery device; comprising a receiving box for installation on a workbench and located on one side of an ink roller, a scraper is installed on the upper side of the side wall of the receiving box close to the ink roller, and the blade of the scraper is in contact with the roller surface of the ink roller; a liquid outlet is opened at the bottom of one side of the receiving box, a collecting bucket is provided on one side of the workbench, and the collecting bucket is located below the receiving box, and the liquid inlet of the collecting bucket is connected to the liquid outlet of the receiving box through a connecting pipe;
[0005] The structure in the above patent, when printing, scrapes the ink roller by the scraper to transfer the excess ink to the receiving box, so as to recover the excess ink. However, when the scraper in the above patent scrapes the ink roller, the ink on the ink roller may be insufficient, which will cause insufficient printing during printing, and thus the working efficiency of the printing machine cannot be effectively guaranteed.
[0006] In view of the above situation, we provide a screen printing machine with an ink collecting and scraping structure. In this device, ink is transferred to the printing plate inside the screen printing plate frame through a scraper. In this way, the scraper can scrape the ink while the ink is being transferred, so that the screen printing plate and the workpiece on the workbench can be effectively printed. During printing, as the ink is transferred, there will be ink residue on the screen printing plate, and the scraper can push the excess ink to the separation point between the screen printing plate frame and the workbench, so that the excess ink passes through the filter and enters the collection box, and the circulation pump and circulation pipe at the bottom of the collection box are used to circulate the excess ink into the ink box, which effectively ensures that the excess ink will not affect the printing quality of the workpiece when the printing machine is working, and effectively improves the working efficiency of the screen printing machine. Utility Model Content
[0007] The utility model aims to provide a screen printing machine with an ink collecting and scraping structure. In the device, the scraper is used to scrape the ink, so that the workpiece between the screen printing plate and the workbench can be effectively printed. When there is excess ink, the scraper is used to scrape the excess ink to the side where the screen printing plate and the workbench are separated, so that the excess ink passes through the filter and then enters the collection box. In this way, impurities attached to the ink can be effectively separated, and the situation where the ink is mixed with impurities and affects the printing quality can be prevented; the ink is recycled through a circulation pump and a circulation pipe to solve the problems of the above-mentioned background technology.

[0018] The utility model, when printing, uses a driving device to translate the movable carriage along the slide rail on the fixed frame, so that during the translation process, the ink in the ink box is transferred to the scraper, and the carriage drives the ink box and the scraper to scrape the ink along the screen printing plate surface inside the screen printing plate frame, so as to realize effective printing processing of the workpiece between the bottom of the screen printing plate frame and the workbench;
[0019] According to the utility model, after the treatment is completed, there will still be residual ink inside the screen printing plate frame. In order not to affect the subsequent printing quality, the excess ink is scraped to the position where the screen printing plate is separated from the workbench by a scraper, so that the ink passes through the screen printing plate and drips onto the filter screen, and the impurities mixed in the ink are effectively separated by the filter screen. The excess ink is gathered in the collection box, and the circulation pump at the bottom of the collection box is used to transmit the ink inside the collection box to the ink box through the circulation pipe, so as to achieve the effect of ink recycling.
