Description

Technical Field

[0001] The utility model relates to the technical field of filter paper punching, in particular to a circular filter paper punching device. Background Art

[0002] Filter paper separates solid particles in liquid or gas, or allows different material components to fully contact, speeding up the reaction time, and protecting the normal operation of equipment or the cleanliness of air. When the fluid or gas enters the filter element with a filter screen of a certain specification, its impurities are blocked, and the clean fluid or gas flows out through the filter paper. The filter paper purifies the contaminated liquid or gas to the state required for production and life, that is, the liquid or gas reaches a certain degree of cleanliness.

[0003] Traditional punching machines on the existing market still have some defects when in use. For example, a lot of waste chips will be generated during use, and a large part of these waste chips will fall on the workpiece and pad to be punched, or when punching, the waste chips will not fall off at the holes of the bottom filter paper, thereby affecting the quality of the filter paper. Therefore, a circular filter paper punching device is proposed to solve the above problems. Utility Model Content
