Pneumatic scraper mechanism capable of automatically regulating degree of parallelism between milling roll bus and scraper blade surface

Abstract

The invention relates to a pneumatic scraper mechanism capable of automatically regulating degree of parallelism between a milling roll bus and a scraper blade surface. The pneumatic scraper mechanism is characterized by being provided with a double-acting air cylinder (1), wherein a front rocker arm (2) and a rear rocker arm (3) are arranged at the two sides of the air cylinder (1); a scraper device is mounted by arranging pressure covers (5), pressure cover bolts (17), supporting bases (11), supporting shaft slide bearings (28), supporting base bolts (29), a transmission shaft (6) and a transmission shaft slide bearing 19; and meanwhile, a scraper guide mechanism is mounted on a scraper base (10) of the scraper device. The pneumatic scraper mechanism reasonably provides contact force between the scraper and a milling roll by virtue of the air cylinder, and is constant in contact force; a scraper automatically follows up after being worn, and scheduled maintenance is not required. The pneumatic scraper mechanism has the characteristics of automatically regulating the degree of parallelism between the milling roll bus and the scraper blade surface, and improving fitness between the scraper and the roll surface and the like.

Description

[0001] Field [0002] The invention relates to the mechanical technical field of a flaking machine, in particular to a pneumatic scraper mechanism on the flaking machine which can self-adjust the parallelism with the roll generatrix. Background technique [0003] As we all know, the flaking machine is an important process mechanical equipment for oil extraction in the oil industry. It usually includes two rollers rotating in opposite directions. Oil materials such as soybeans, corn germ, rapeseed, cottonseed, etc. After the flakes are extruded, they are discharged from the bottom of the rollers. The function of the scraper is to scrape off the flakes attached to the surface of the rollers. Rolling is a continuous process. The scraper mechanism of the existing flaking machine is roughly divided into heavy block type and spring type. No matter which type is used, it is necessary to manually adjust the contact force between each scraper and the roll, and after a period of work,...

Problems solved by technology

The scraper mechanism of the existing flaking machine is roughly divided into heavy block type and spring type. No matter which type is used, it is necessary to manually adjust the contact force between each scraper and the roll, and after a period of work, it needs to be worn out. Artificially readjust the contact force, and the size of the contact force is only based on the experience of the worker, and the contact force of each scraper cannot be adjusted exactly the same, resulting in inconsistent wear; and, after a new flaking machine, new roll or roll grinding , the parallelism between the busbar of the roller surface and the blade surface of the scraper is not very ideal, and it takes a period of running-in to make the scraper and the roller surface fit well. For scraper blades made of wear-resistant materials, this is a long process, so it will There is a problem that the embryo flakes are not scraped clean, that is, the material is thrown away, and sometimes it even affects the quality of the embryo flakes
