Description

Technical Field

[0001] The utility model relates to a paperboard glue scraping device with uniform glue scraping, belonging to the technical field of paperboards. Background Art

[0002] Cardboard, also known as paperboard, is a thick paper sheet made from various pulps and composed of interwoven fibers. It is usually made from various plant fibers, sometimes with non-plant fibers mixed in, and is made on a cardboard machine. Some special cardboards are also mixed with animal fibers such as wool or mineral fibers such as asbestos. During the production of cardboard, some residual glue, waste ink, paper scraps and other impurities will be produced. If they are not removed in time, the quality of the cardboard and the printing effect will be affected. Glue scraping can effectively remove surface impurities, ensure the flatness and ink absorbency of the cardboard surface, thereby improving the printing quality and processing performance of the cardboard.

[0003] Authorization announcement number (CN218223242U) discloses a printed cardboard scraping device, which relates to the field of cardboard processing, including a processing table and a scraper structure, characterized in that: a conveyor belt is movably provided on the inner side of the processing table, and a mounting frame is fixed to the top of the processing table, and a hydraulic push rod is installed on the inner wall of the mounting frame. The utility model is provided with a first heat-conducting rod, a second heat-conducting rod, a heating tube and a first scraper, and the first scraper and a plurality of second scrapers move downward to scrape glue. The battery transmits electric energy to the heating tube through the power line. After the heating tube is running, it generates heat and transfers the heat to the first heat-conducting rod below. The first heat-conducting rod transfers the heat to the second heat-conducting rod through the heat-conducting block and the heat-conducting groove, so that the first heat-conducting rod inside the first scraper and the second heat-conducting rod inside the second scraper both become high in temperature, and the high temperature is transferred to the ends of the first scraper and the second scraper, thereby preventing the glue on the scraper from drying;

[0004] However, when using the above technology, the angle of the scraper itself may be difficult to adjust. If the scraper angle is difficult to adjust, the scraper will not be able to fully contact the surface of various cardboards. This poor contact will result in uneven scraping effect and inability to completely remove excess glue and impurities on the cardboard surface, which may cause scratches or marks on the cardboard surface, damaging the flatness and aesthetics of the cardboard, and ultimately affecting the overall performance and appearance quality of the product.

[0005] Therefore, a cardboard glue scraping device with uniform glue scraping is proposed. Utility Model Content

[0029] By adjusting the setting of the mechanism 3, it is possible to adapt to different types and thicknesses of cardboard, thereby increasing the scope of application and flexibility of the equipment and improving production efficiency. The scraper can be fitted to the surface of various cardboards, ensuring a uniform scraping effect, thoroughly removing excess glue and impurities on the cardboard surface, and improving the flatness and aesthetics of the cardboard, thereby enhancing the overall performance and appearance quality of the product.

[0030] Example 2

[0031] In one embodiment, a guide block 4 is fixedly connected to the top of the threaded sleeve 303, a guide groove 5 is opened at the top of the inner side of the frame 2, the upper end of the guide block 4 is slidably connected to the inner side of the guide groove 5, a protective cover 6 is fixedly installed on the right side of the surface of the frame 2, the first motor 301 is located on the inner side of the protective cover 6, and positioning bolts 7 are fixedly installed on all four sides of the surface of the substrate 1, and the lower end of the positioning bolts 7 passes through the substrate 1 and extends to the bottom of the substrate 1.

During the movement of the connecting frame 305, the transmission gear 307, the driven gear 309, the ring gear 310, the connecting plate 311 and the scraper 313 will move downward, so that the scraper 313 contacts the surface of the cardboard. At this time, the spring 312 provides tension, which will drive the scraper 313 to move downward, so that the scraper 313 is fully fitted with the cardboard. At this time, the first motor 301 can be started to The threaded rod 302 at the output end is driven to rotate. When the threaded rod 302 rotates, the threaded sleeve 303 and the electric telescopic rod 304 are driven to move laterally through the action of the threaded connection. When the surface of the cardboard is uneven or the size of the cardboard to be processed is inconsistent, the second motor 306 can be started to work. After the second motor 306 is started, it drives the transmission gear 307 to rotate under the action of tooth meshing. When the transmission gear 307 rotates, it drives the ring gear 310, the connecting plate 311 and the spring 312 to rotate, thereby adjusting the angle of the spring 312 so that the spring 312 fits better with the surface of the cardboard during scraping.
