Description

Technical Field

[0001] The utility model relates to the technical field of filter element processing, in particular to a novel oil-gas separation filter element winding mechanism. Background Art

[0002] With the widespread use of mechanical equipment in people's lives, the pace of people's production and life has been accelerated and efficiency has been improved. The utilization rate of oil-gas separation filter elements, the main components of oil-injected rotary air compressors, is also increasing.

[0003] At present, there is a type of filter element inside the oil and gas separation filter (referred to as oil filter element) that is wound with filter paper and then connected into a cylindrical shape by double-sided tape. Since there are many specifications of wound filter elements, the lengths and diameters of the filter elements are also different. For the process of winding the filter paper, it is necessary to produce it according to the diameters and lengths of various filter elements. The existing oil filter element winding machine, the umbrella-shaped telescopic mechanism will often stretch the filter element filter screen when it is unfolded to adjust the processing diameter of the filter element, causing the filter paper to deviate when it is wound, resulting in a decrease in production quality. Summary of the invention

[0004] In view of the above problems existing in the existing oil filter element winding machine, the present invention aims to provide a new oil and gas separation filter element winding mechanism which can improve production efficiency, meet production requirements, reduce labor costs and improve product quality.

[0023] As a further improvement and optimization of this solution, it also includes two bearing seats, and the main shaft is rotatably mounted on the two bearing seats.

[0024] As a further improvement and optimization of this solution, the second motor is a three-box AC asynchronous motor.
