Description

Technical Field

[0001] The utility model relates to the technical field of near-infrared inspection, in particular to a cross-shaped large-spot probe. Background Art

[0002] The granulating fluidized bed is used to complete the processes of granulation, coating and drying at one time during the pharmaceutical process and has been widely used in pharmaceutical production. The diameter of the particles obtained by the fluidized bed not only affects the subsequent process flow, but also directly affects the quality of the final drug. However, the existing operating parameters of the granulating fluidized bed are fixed during the production process, while the raw material batches and environmental conditions change with time, but the operating parameters cannot be adjusted accordingly, resulting in poor consistency of drug quality or even unqualified products.

[0003] By performing real-time on-line detection of the particle diameter, the operating parameters can be adjusted according to the changes, so that the particle diameter distribution is within the desired range, thereby monitoring the granulation process and ensuring the drug quality. Therefore, on-line detection of the particle diameter during the fluidized bed granulation process is very necessary.

[0004] Quality inspection has always been an important step to ensure the qualified quality of drugs. The common on-line detection devices in the fluidized bed granulation process take samples and detect them by inserting sampling parts into the fluidization chamber when the fluidized bed is working. However, the fluidized bed is a closed working space, and the entry of the sampling parts may interfere with the normal fluidized granulation flow field and affect the granulation process and results.

[0005] The "Detection Sensor" with the Chinese patent application number CN202020789388.9 discloses that the detection sensor includes a matrix body. An emission optical path and a recovery optical path are arranged in the matrix body. There are two or more emission optical paths. All the emission optical paths are incident from the outer surface of the window glass, and all the emission optical paths intersect at the same area. The area is located outside the matrix body; the area is located on the recovery optical path; the emission optical path includes a light source and a convex lens; the recovery optical path includes a light receiver and a convex lens; the light source has a power connection part, and the light receiver is connected to an optical fiber.

[0006] In the prior art, when checking the components of materials on a conveyor belt or in a drying machine, there are several significant drawbacks. First, the inspection process is often very difficult and requires a large amount of manpower to ensure accuracy and efficiency. Second, the existing detection equipment usually needs to be close to the materials for inspection, which not only increases the complexity of the operation, but also may interfere with the materials. In addition, the equipment cost is high and the installation process is cumbersome, which limits its practical application. Summary of the Invention

[0007] The present utility model mainly solves the deficiencies existing in the prior art, and provides a cross-shaped large-spot probe, which has a relatively long focal length and can detect materials from a slightly longer distance. It reduces the direct contact of the equipment with the materials, reduces the interference with the materials, and at the same time improves the flexibility and efficiency of detection.

Four lamp mounting seats are provided around the fiber collimator mounting seat and are evenly distributed in an annular shape and are integrally formed with the fiber collimator mounting seat in a cross-shaped structure. The central axis of the lamp mounting seat and the central axis of the fiber collimator mounting seat form an inclined angle with the front lower and the rear higher.

[0010] Preferably, the lamp assembly includes a lamp holder. A lamp is nested at the front end of the lamp holder. A lamp plug is threadedly sleeved and fixed to the lamp holder at the rear end of the lamp.

It reduces the direct contact of the equipment with the materials, reduces the interference with the materials, and at the same time improves the flexibility and efficiency of detection. The farther focal length, through the angle design, ensures that the distance from the intersection of the bulb axis and the optical fiber diameter axis to the probe plane is farther.
