Problems solved by technology

Corrugated felt is a metal fiber sintered material, which has certain elasticity after corrugated molding. The flat plate is a steel plate, which has strong rigidity. For problems such as core tube slippage and inaccurate filter diameter, the typical solution of the existing winding device is: increase the tension force during winding, use a deviation correction device and measure the diameter; for corrugated felt and flat plate winding, the typical structure cannot meet the requirements of the end face requirements, tightness requirements and diameter requirements

Abstract

The invention relates to a spiral winding device for manufacturing a tail gas filter. The tail gas filter comprises a filter element; and the filter element includes a core pipe, a flat plate and a corrugated felt. The spiral winding device is characterized by comprising a first conveying mechanism for conveying the flat plate, a first shearing mechanism for shearing the flat plate, a second conveying mechanism for conveying the corrugated felt, a second shearing mechanism for shearing the corrugated felt, a welding mechanism for welding starting ends of the flat plate and the corrugated felt on the core pipe, a winding mechanism for winding the flat plate and the corrugated felt on the core pipe, and a stop disc mechanism used for fixing the core pipe. The spiral winding device cannot generate dislocation of the end surface of the obtained filter element, is high in winding efficiency, and belongs to the field of tail gas filter production devices.

Description

technical field [0001] The invention relates to the field of tail gas filter production devices, in particular to a spiral winding device for making tail gas filters. Background technique [0002] The exhaust filter is a device for collecting and filtering carbon particles in the exhaust of diesel engines. Its function is to reduce the emission of particulate matter by capturing and filtering the carbon particles in the exhaust of diesel engines to meet the requirements of exhaust emissions. The exhaust gas filter includes a shell baffle assembly and a filter element, wherein the filter element includes a core tube, a corrugated felt and a flat plate, and the filter element is spirally wound after the corrugated felt and a flat plate are welded on the core tube. Corrugated felt is metal fiber sintered material, which has a certain degree of elasticity after corrugated molding. The flat plate is steel plate, which has strong rigidity. For problems such as core tube slippage ...
