End face pattern centering detection device for coaxial core filter rod

Abstract

The invention provides an end face pattern centering degree detection device for a coaxial core filter rod. The coaxial core filter rod includes an inner core and an outer core wrapped around the outer circumference of the inner core. The end surface pattern centering degree detection device includes: contrast transparent The standard outer core pattern that is the same as the end face pattern of the outer core and the standard inner core pattern located at the center of the standard outer core pattern are printed on the control transparent sheet; The central hole through which the filter rod passes, the diameter of the central hole is adapted to the diameter of the coaxial core filter rod, and the main body of the device has a clamping structure for adding a contrast transparent sheet, so that the contrast transparent sheet is vertically sealed in the central hole on a port. Through the device for detecting the centering degree of the end face pattern of the coaxial core filter rod of the present invention, the inspector can quickly and accurately detect the centering degree of the inner core of the coaxial core filter rod in the appearance inspection of the coaxial core filter rod.

Description

technical field [0001] The invention relates to the field of filter rod detection, in particular to a device for detecting the centering degree of end face patterns of a coaxial core filter rod. Background technique [0002] In recent years, a variety of new special filter rods have appeared. The new special filter rods include special hollow filter rods with special patterns on the end surface, paper coaxial core filter rods, paperless coaxial core filter rods and other filter rod products. This filter rod product is processed by a special process, and the end face has a special shape pattern. These patterns are usually circular, and can also be complex patterns such as heart shape, plum blossom shape, and pentagram shape. The centrality of these patterns (patterns such as circles are called concentricity) affects the appearance quality of the filter rod and is an important technical parameter of the filter rod. [0003] The existing centering degree detection method is us...

Problems solved by technology

This method has accurate measurement results, but the equipment used needs to be connected to a computer, and the equipment is large and not suitable for carrying

This detection method is only suitable for the unified detection of finished products, and is not suitable for workers to control the centering degree of products during production. During production, workers usually observe the centering degree of the filter rod end face graphics with the naked eye based on experience, and the accuracy is not high.
