The screen printing machine is a machine that prints text and images. It is a general term for machines or equipment used to produce printed products. The screen printing machine is a more representative printing equipment among stencil printing machines. In addition to silk, the materials used to make the screen can also be nylon wire, copper wire, steel wire or stainless steel wire. It can be divided into flat screen printing machines, curved screen printing machines, rotary screen printing machines, etc. Due to the wide range of uses of screen printing machines, it is necessary to optimize the screen printing machine.

[0003] For example, a screen printing machine is disclosed in the Chinese utility model patent with the announcement number CN203449721U. Although the above-mentioned prior art greatly improves the number of printing times compared with the traditional screen printing machine, saves ink and reduces the printing cost, the scraper will be worn due to continuous friction during the printing process. When it is worn to a certain extent, it needs to be replaced. The replacement of the scraper is relatively troublesome. Not only does it require the machine to be stopped, but it also requires the screwing of multiple screws. When screwing the screws, it is easy to cause the machine to shake and need to readjust the position. This results in a long time required to replace the scraper, which affects the production and printing speed of the printing machine. Therefore, it is necessary to design a screen printing machine that can quickly replace the scraper of the printing machine. Utility Model Content

[0028] The implementation principle of a screen printing machine scraper that is easy to clean and disassemble in the embodiment of the present application is as follows: when the scraper 203 of the printing machine body 1 needs to be replaced, the two pushing plates 7 are pressed to allow the two pushing blocks 8 to push the limiting block 302 into the fixed groove, so that the effect of the fixing block 202 being restricted by the fixing mouth will disappear, so that the fixing block 202 can be pulled out from the inside of the mounting block 201, and before pulling it out, the connecting column 10 is slid to move the stopper 11 away, so that the cleaning plate 402 will rotate down, and the cleaning plate 402 is pressed to pull the pulling plate 6 to pull out the fixing block 202. During the pulling process, the scraper 203 will contact the cleaning groove of the cleaning plate 402, thereby The dirt on the scraper 203 is scraped and cleaned, and a new scraper 203 and a fixed block 202 are inserted into the mounting block 201. During the insertion process, the new scraper 203 can also be scraped and cleaned. The limiting block 302 of the fixed block 202 enters the fixed opening of the mounting block 201 under the push of the push spring 301, so that the new fixed block 202 and the scraper 203 will be fixed. After replacing the scraper 203, the cleaning plate 402 is rotated upward, and the cleaning plate 402 is blocked by the stopper 11 to prevent the cleaning plate 402 from affecting the printing of the scraper 203. This arrangement allows the scraper 203 to be replaced quickly and the scraper 203 can be cleaned.
