Technical Field
[0001] This utility model relates to the field of printing machine technology, and in particular to a scraper mechanism for a printing printer. Background Technology
[0002] In traditional laser printers or copiers, the toner cartridge (also known as a drum or toner box) is a key component for storing and delivering toner. The toner is heated and transferred onto paper to form an image. For printing printers, especially those using inkjet technology, ink cartridges are typically used to store ink. These cartridges are usually designed separately for each color for easy replacement and maintenance. Inside the printer are many tiny printheads that precisely control the position and amount of ink ejected. When a print command is issued, the printheads eject ink onto the printing material according to the image requirements. The doctor blade is another important component of the printing press, typically used to remove excess ink or coating from the printing plate surface to ensure clear, accurate, and vibrant prints.
[0003] A search revealed Chinese Patent Publication No. CN221873522U, which discloses a scraper mechanism for a printing printer, comprising an electric cylinder, a mounting plate, and a scraper holder. Multiple electric cylinders are provided and fixed to the mounting plate. The output end of each electric cylinder passes through the mounting plate and is fixedly connected to the top of the scraper holder. Two scraper holders are symmetrically arranged and slidably connected to each other. A fixing plate for easy scraper installation is rotatably connected to the scraper holder. A scraper for printing is fixed to the bottom of the fixing plate by bolts.
[0004] Because the scraper is fixed to the clamping plate with bolts, the scraper needs to be supported while installing it, and all the bolts must be tightened before it can be loosened, which makes the scraper installation inconvenient. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.
[0024] The present invention will be further described below with reference to the accompanying drawings:
[0025] like Figure 1-Figure 5As shown, a scraper mechanism for a printing printer includes a mounting plate 1. The mounting plate 1 is connected to a height adjustment component below the printing machine frame. A blade holder 2 is bolted to the bottom of the mounting plate 1. A scraper body 3 is fixedly connected inside the blade holder 2. The blade holder 2 is U-shaped with its opening facing downwards. The scraper body 3 abuts against the inner top wall of the blade holder 2. The blade holder 2 and the scraper body 3 are fixed together by bolts.
[0026] Two sets of auxiliary mechanisms are symmetrically arranged on the front and rear sides of the mounting plate 1. The auxiliary mechanisms include extension plates 401 bolted to the front and rear side walls of the mounting plate 1. An electric push rod 402 is fixedly connected to the extension plate 401. A horizontal plate 403 is fixedly connected to the bottom of the electric push rod 402. A fixed plate 404 is connected to the horizontal plate 403 through an elastic component. The elastic component includes a slide rod 501 slidably connected in the horizontal plate 403. One end of the slide rod 501 extends out of the horizontal plate 403 and is fixedly connected to a pull handle 502. The other end of the slide rod 501 is fixedly connected to the fixed plate 404. A spring 503 is connected between the fixed plate 404 and the horizontal plate 403. The spring 503 is wrapped around the outer periphery of the slide rod 501.
[0027] A number of support seats 405 are fixedly connected to the side of the fixing plate 404 near the scraper body 3. The front and rear sets of support seats 405 are pressed together. The side of the support seats 405 that is close to each other is provided with a placement groove. When the placement grooves on the two sets of support seats 405 are spliced together, they form a V-shape with the tip pointing downwards. The scraper body 3 is placed in the placement groove, which improves the fit between the scraper body 3 and the support seat 405. The side of the two support seats 405 that is close to each other is provided with an installation groove. A magnetic strip 406 is provided in the installation groove. The polarity of the two magnetic strips 406 that are close to each other is opposite. When the distance between the two support seats 405 reaches a certain point, the two magnetic strips 406 attract each other, causing the two support seats 405 to press together and improving the supporting force of the two support seats 405.
[0028] A guide assembly is also provided between the horizontal plate 403 and the fixed plate 404. The guide assembly is used to move the fixed plate 404 horizontally. The guide assembly includes two limiting plates 601. The limiting plates 601 are bolted to the side of the horizontal plate 403 near the scraper body 3. A T-shaped groove 602 is opened on the side of the two limiting plates 601 that are close to each other. T-shaped blocks 603 are fixedly connected to both sides of the fixed plate 404. The T-shaped blocks 603 are slidably connected in the T-shaped groove 602. Through the cooperation of the T-shaped blocks 603 and the T-shaped groove 602, the fixed plate 404 is guided and limited, improving the stability of the fixed plate 404. The limiting plates 601 are distributed on both sides of the scraper body 3 to prevent the limiting plates 601 from abutting against the scraper body 3 and causing interference during the upward movement of the horizontal plate 403.
[0029] Working principle: In use, the mounting plate 1 is directly connected to the height adjustment component under the printing machine frame. When installing the scraper body 3, first insert the scraper body 3 into the blade holder 2 and make the scraper body 3 abut against the inner top wall of the blade holder 2. Then, the electric push rod 402 raises the support base 405 until the scraper body 3 abuts against the support base 405. The two abutting support bases 405 support the scraper body 3, avoiding manual installation of the scraper body 3 and improving the convenience of installation. Then, tighten the bolts to install the scraper body. After the scraper body 3 is fixed to the scraper holder 2, the sliding rod 501 is driven by the pull handle 502 to move the fixing plate 404 away from the scraper body 3, so that the support seat 405 is separated from the scraper body 3. Then, the support seat 405 is raised to a suitable height by the electric push rod 402. The pull handle 502 is released, and the fixing plate 404 moves towards the scraper body 3 under the action of the spring force 503, so that the support seat 405 abuts against the scraper body 3, providing clamping force for the scraper body 3 and improving the stability of the scraper body 3.
