Description

Technical Field

[0001] The utility model relates to the technical field of microscopic inspection instruments, in particular to a microscopic inspection instrument used for detecting spinnerets. Background Art

[0002] The spinneret is a very important equipment in chemical fiber production. In the process of chemical fiber production, the raw materials are melted and passed through spinneret holes of different shapes to obtain fiber filaments of different shapes and structures.

[0003] The spinneret hole diameter is very small, about 0.2mm in diameter. During use and handling, dust may clog the spinneret hole, or carbide may adhere to the inner wall of the spinneret hole due to improper handling, making the cross-sectional shape of the fiber raw yarn incomplete and the size unequal, affecting product quality.

[0004] The spinneret holes need to be inspected before the components are assembled. The existing microscope can only inspect spinnerets with straight holes, but cannot inspect the two-component oblique hole spinnerets used in our production.

[0005] The existing microscope can only detect spinnerets with straight holes, which are vertical. However, the spinnerets we use in production have inclined holes, which have a certain angle with the ground. After the light source of the existing microscope passes through the spinneret, the image of the spinneret cannot be collected because the objective lens is vertical.

[0006] Or only detect a single-component inclined hole spinneret. When using it, first look at the micropores of one component, and then adjust the angle to look at the micropores of the other component, which doubles the workload of detection. Utility Model Content
