Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to automatic corner cutting equipment for processing air filter elements. Background Art

[0002] The air filter element is a kind of filter, also called air filter cartridge, air filter, style, etc. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operating rooms and various precision operating rooms.

[0003] The engine needs to inhale a large amount of air during operation. If the air is not filtered, the dust suspended in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. Large particles entering between the piston and the cylinder will cause serious "cylinder pulling", which is particularly serious in dry and sandy working environments. The air filter is installed in front of the carburetor or the intake pipe to filter out dust and sand in the air to ensure that sufficient and clean air enters the cylinder.

[0004] According to the filtering principle, air filters can be divided into filtering type, centrifugal type, oil bath type, and composite type. Commonly used air filters in engines include inertial oil bath air filters, paper dry air filters, polyurethane filter element air filters, etc. The inertial oil bath air filter undergoes three levels of filtration, namely inertial filtration, oil bath filtration, and filtration filtration. The latter two air filters are mainly filtered by filter element filtration. The inertial oil bath air filter has the advantages of small intake resistance, adaptability to dusty and sandy working environments, and long service life. It was previously used in various models of automobile and tractor engines. However, this type of air filter has low filtration efficiency, heavy weight, high cost, and inconvenient maintenance, and has gradually been eliminated in automobile engines. The filter element of paper dry air filter is made of microporous filter paper treated with resin. The filter paper is porous, loose, folded, has certain mechanical strength and water resistance, and has the advantages of high filtration efficiency, simple structure, light weight, low cost, and convenient maintenance. It is the most widely used automotive air filter. The filter element of polyurethane filter air filter is made of soft, porous, sponge-like polyurethane with strong adsorption capacity. This air filter has the advantages of paper dry air filter, but low mechanical strength, and is widely used in car engines.

[0005] During the processing of air filter elements, it is necessary to trim the corners of the end faces of the finished air filter elements. Corner trimming tools are commonly used to cut out the corners through scissor-like cutting force. This method will cause the air filter element to be squeezed, which will cause pressure on the air filter element and easily cause deformation. In view of this, an automatic corner trimming equipment for air filter element processing is developed. Utility Model Content
