Description

Technical Field

[0001] The utility model relates to the technical field of tobacco packaging machinery, in particular to a visually adjustable installation structure for a beam-type optical fiber amplifier. Background Art

[0002] In the process of cigarette production, pack shortage is a common problem. Traditional weighing-type pack shortage detectors and eddy current induction-type pack shortage detection devices have certain limitations. The cigarette rod photon detection technology has the advantages of high recognition rate, fast detection speed, reasonable design, and easy maintenance, which can well meet the needs of cigarette production.

[0003] In the actual process of photon missing packet detection, in order to avoid false detection, it is necessary to trigger and locate the cigarette rod entering the photon detection equipment. Existing positioning instruments generally use a through-type fiber optic sensor. Since the through-type fiber optic sensor needs to install the transmitting end and the receiving end on both sides of the object to be detected, and ensure that the two are accurately aligned, the installation process takes a lot of time, which is not conducive to ensuring production efficiency. The light and humidity in the external environment may also affect the signal transmitted by the optical fiber, resulting in inaccurate detection results, which is not conducive to controlling production costs and ensuring production efficiency.

Correspondingly, there are also four N-pole planar magnets, which are installed at the four corners of the visible window plate and correspond one-to-one with the installation positions of the S-pole planar magnets.

[0010] Furthermore, the S-pole planar magnet and the N-pole planar magnet can be installed detachably, and exhaust holes are provided at the installation positions.

[0011] Furthermore, it also includes a handle, which is fixed to the outer surface of the visible window panel.
