Description

Technical Field

[0001] The invention relates to the technical field of scraper equipment, in particular to a paper machine drying cylinder scraper equipment for processing pillow base paper. Background Art

[0002] With the development of papermaking technology, packaging paper companies must expand the variety of packaging products to improve product quality and, in turn, enhance their market competitiveness. However, in the production of low-weight containerboard, the scraper equipment on high-speed papermaking machines often fails to clean effectively, resulting in product quality issues such as paper breaks and dirty paper surfaces, seriously affecting production efficiency and quality.

[0003] The drying cylinder of a papermaking machine is a key component for paper drying. Made of cast iron, it consists of a cylinder body and two covers, with an outer diameter typically ranging from 1000 to 3000 mm. During operation, steam circulates through the cylinder to dry and polish the paper being conveyed. To maintain a clean surface, a scraper is required. Existing scrapers are fixed to a scraper assembly, with the blade contacting the cylinder surface. The dryer rotates continuously during use, forcing the blade backward and causing vibration. This causes severe wear on the blade, leading to inconsistent contact between the blade and the cylinder surface, uneven drying, and reduced scraper life. The inconvenient scraper replacement and removal results in incomplete cleaning of the cylinder surface, which can easily cause paper breakage, paper defects, and even cylinder spots, resulting in poor paper drying results. Summary of the Invention

[0004] The object of the present invention is to provide a paper machine drying cylinder scraper device for processing pillow base paper to solve the problems raised in the above background technology.

[0005] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion. The top end of the spring is fixedly connected to the top of the movable plate, and the bottom end of the spring is fixedly connected to the top of the movable plate. The top of the spring is fixedly connected to the bottom of the movable plate, and the bottom end of the movable plate is fixedly connected to the top of the movable plate. The top of the splint is evenly spaced, and screws are respectively provided on the splint. The scraper is provided with a slider at the bottom end of the scraper, and the top of the slider is fixedly connected to the scraper. The scraper is movably connected to the splint around the periphery, and circular holes are evenly spaced on the scraper, and the circular holes are respectively threaded with screws.

[0006] Furthermore, the transmission motor is in transmission connection with the shaft.

[0007] Furthermore, a brake is installed on one side of the universal wheel.

[0008] Furthermore, the slider is slidably connected to the slide groove.

[0009] Furthermore, the bottom end of the drying cylinder and the top end of the scraper are in contact with each other.

[0010] Furthermore, the transmission motor is electrically connected to the power supply via a circuit.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The transmission motor of the present invention drives the drying cylinder to rotate, thereby drying the paper. Simultaneously, a spring within the base extends the telescopic support rod, driving the scraper on the clamping plate against the drying cylinder, ensuring a tight fit between the two. This facilitates the scraper's cleaning of the drying cylinder surface and maintains a smooth roller surface, thereby ensuring the quality of the base paper. BRIEF DESCRIPTION OF THE DRAWINGS
