Description

【Specification】

[Name of invention]

Lubricant Feeder

Technical Field

<1> The present invention relates to a lubricant supply device, wherein the follower plate is smoothly and easily upwardly separated from the inner bottom surface of the lubricant container.

<2>

Background Art

In general, a pump having a structure in which a high viscosity lubricant such as grease is directly discharged in a container has a high grease viscosity, and thus a poor flow rate causes a considerable amount to remain on the inner wall of the container, resulting in waste or loss of grease.

<4>

<5> As a method for scraping off the remaining grease on the inner wall to compensate for this, a method of attaching a separate scraper wing for attaching the inner wall of the vessel to the stirring blade at the bottom of the pumping mechanism is devised. It is difficult to fix the center of the container to match the center of the pumper's bend, so the side scraper blade is overloaded and broken or scraped off to one wall. Weaknesses made it difficult to achieve what was originally intended.

<6>

<7> In addition, follower plates are installed in various grease pumps (pneumatic, electric, manual type) that use a rod-type pumping mechanism part in a grease container to scrape off the grease on the inner wall. When the grease is exhausted and the follower plate is in close contact with the bottom of the container, a vacuum is created on this contact surface, which requires a very large force to separate the follower plate and the container, which is difficult to remove.

In other words, if the follower plate contacts the bottom of the container while the grease in the container is completely discharged, there is no air on the contact surface, so that the follower plate and the bottom of the container are in close contact with each other, making it difficult to separate them.
