Filter net multi-size positioning roller

Abstract

The invention provides a filter net multi-size positioning roller. The filter net multi-size positioning roller comprises a shaft sleeve. Four adjusting blocks are arranged on the periphery of the shaft sleeve and are concentric to the shaft sleeve, and the sections of the adjusting blocks are of a fan-shaped structure. The radius of the inner side arc faces of the adjusting blocks is R, the radius of the outer side arc faces of the adjusting blocks is R', the radius of the outer circumference face of the shaft sleeve is r, and R'=2R=2r. The two end faces of each adjusting block are provided with adjusting slotted holes of a rectangular structure, and the adjusting blocks are further provided with through holes vertically communicating with the adjusting slotted holes. The shaft sleeve isprovided with locking screws matched with the through holes. The upper ends of the locking screws stretch into the through holes, the adjusting slotted holes are internally provided with adjusting circular plates which are in threaded fit with the locking screws, and a plurality of vertically-arranged anti-skid strips are arranged on the circumferences of the adjusting circular plates. A pluralityof limiting plates of an arc structure are arranged between every two adjacent adjusting blocks in a sliding manner, and the circle centers of the limiting plates coincide with the circle centers ofthe adjusting blocks. The problems that the filter net length is determined through a manual lineation manner, and mixing is likely to happen when many kinds and many dimensions are produced are solved.

Description

technical field [0001] The invention relates to the field of filter screen cutting equipment, in particular to a filter screen multi-size positioning roller. Background technique [0002] The filter element in the oil filter machine is the core filter component. The filter element includes multiple filter layers and fillers. In order to adapt to different filtration capacity, the processing capacity of the oil filter machine is related to the length of the filter element and the diameter of the filter screen. The oil filtering effect of the oil filter is also graded according to the number of layers of the filter screen. Generally, the oil filter with a higher filtration level contains filter screens of various diameters to separate multiple filter spaces for filtering. [0003] The diameters of the filter screens used in different series of oil purifiers have various specifications, and the fixed-length filter screens are welded into a columnar structure before use. The ex...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a filter screen multi-size positioning roller, which solves the problem that the length of the existing filter screen is determined by manual scribing, which is easy to produce in many types and sizes. When there are many specifications, there will be confusion, which will cause the problem that the filter cannot be used normally
