Description

Technical Field

[0001] The utility model relates to the technical field of pencil lead raw material processing, in particular to a raw material mixing device for pencil lead manufacturing. Background Art

[0002] The main component of pencil lead is graphite. Actually, pencil lead is made by mixing graphite and clay in a certain ratio. Graphite is soft and one of the softest minerals. A light scratch on paper leaves a mark. Therefore, if the graphite content in the pencil lead is too high, it will be too soft and difficult to write with. If the clay content is too high, the lead will be too hard and the writing effect will be poor. Therefore, it is necessary to fully mix the graphite and clay in a certain ratio to make the pencil lead.

[0003] Currently, when using a pencil lead raw material mixing device, raw materials tend to adhere to the inner wall of the device. Therefore, some people have come up with the idea of ​​providing a scraper on the stirring device to scrape off the raw materials adhering to the inner wall of the device during the mixing process. For example, Chinese utility model patent No. CN221452457U specifically discloses a high-efficiency raw material mixing device for pencil lead manufacturing.

[0004] However, in actual use, the raw material mixing device for pencil lead manufacturing is found to screen the mixed raw materials directly onto the filter plate during filtration. However, this screening method can easily lead to accumulation of raw materials, causing blockage and affecting its normal use. Utility Model Content
