Description

Technical Field

[0001] The utility model relates to the technical field of near-infrared moisture meters, and more specifically to a supplementary lighting device for a near-infrared moisture meter. Background Art

[0002] An on-line near-infrared moisture meter is an optical measuring instrument that analyzes the energy of near-infrared spectra in a specific band; the mathematical model for calculating the moisture value of an on-line near-infrared moisture meter is established under the optimal illuminance value. If the measured material can be kept under a constant optimal illuminance, it will help improve the measurement accuracy of the on-line near-infrared moisture meter.

[0003] However, in an industrial environment, there may be changes in sunlight and various lights, and it is difficult to control the changes in the light intensity of each band. Sunlight or other lighting tubes may also project onto the measured material. Although the instrument itself can resist the influence of most lights, there will inevitably be a small part of the influence on the measurement result. Content of the Utility Model

[0026] A supplementary lighting device for a near-infrared moisture meter, such as Figures 1 to 3 As shown, the device includes a housing 1, which contains a light-blocking chamber 2. The housing 1 has a first opening 3 and a second opening 4 at its upper and lower ends, respectively, communicating with the light-blocking chamber 2. A fixing assembly for connecting a near-infrared moisture meter 16 is provided on the top of the housing 1. The near-infrared moisture meter 16 can be mounted on the top of the housing 1 using the fixing assembly. The housing 1 covers the material to be tested 15 through the second opening 4. The near-infrared moisture meter 16 irradiates the material 15 from above through the first opening 3. The light-blocking chamber 2 isolates most of the external light, keeping the material 15 under constant illumination, avoiding the influence of external light, and improving measurement accuracy.

[0027] The fixing assembly includes two limiting rods 9 symmetrically arranged on the top of the housing 1. The two limiting rods 9 are distributed on both sides of the first opening 3, and the near-infrared moisture meter 16 can be clamped between the two limiting rods 9.

[0028] The limiting rod 9 includes a vertical plate 901, and a horizontal plate 902 is horizontally arranged at the top of the vertical plate 901. The horizontal plates 902 of the two limiting rods 9 face each other. When the near-infrared moisture meter 16 is installed, the vertical plate 901 and the horizontal plate 902 are respectively in contact with the side wall and the top of the near-infrared moisture meter 16. And two first threaded holes 13 are respectively formed in the horizontal plate 902. The horizontal plate 902 and the near-infrared moisture meter 16 are connected by bolts, so as to fix the near-infrared moisture meter 16 on the top of the housing 1.

[0029] A retaining wall 10 protrudes from the top of the housing 1. The retaining wall 10 is in a "C" shape, and one side is open, forming a semi-closed structure. When the near-infrared moisture meter 16 is installed, it can penetrate into the housing 1 from the open side of the retaining wall 10. When the three-side side walls of the near-infrared moisture meter 16 are in contact with the retaining wall 10, it is aligned with the first open end 3. And at this time, the first screw hole is just aligned with the threaded hole at the top of the near-infrared moisture meter 16, saving the alignment time and making the installation more convenient.

[0030] In this embodiment, the horizontal plate 902 and the vertical plate 901 are integrally formed, and the limiting rod 9 is integrally formed on the retaining wall 10. The two limiting rods 9 are respectively located on two symmetric sides of the retaining wall 10.

The control board 8 controls the light intensity of the light supplementing member 5 through the light sensor 6 and the light regulator 7, so as to keep the best lighting conditions in the light blocking chamber 2.

[0032] The light supplementing member 5 is an annular lighting lamp belt arranged on the inner top wall of the light blocking chamber 2. The annular lighting lamp surrounds the outside of the first open end 3, making the light in the light blocking chamber 2 more uniform.

[0033] A light blocking plate 11 protrudes from the bottom of the first open end 3 towards the inside of the light blocking chamber 2. The light blocking plate 11 extends vertically downward. The light blocking plate 11 surrounds the inside of the light supplementing member 5 in a circle. Through the blocking of the light blocking plate 11, the light supplementing member 5 is guided to irradiate downward, avoiding the diffusion of the light of the light supplementing member 5 at the first open end 3 and interfering with the near-infrared moisture meter 16, which helps to improve the measurement accuracy.

[0034] An installation chamber 12 is arranged on one side of the housing 1. The installation chamber 12 is adjacent to the light blocking chamber 2. The light regulator 7 and the control board 8 are arranged in the installation chamber 12. The light sensor 6 is arranged on the inner side wall of the light blocking chamber 2 to monitor the illuminance value in the light blocking chamber 2. The light supplementing member 5 is electrically connected to the light regulator 7, and the light sensor 6 and the light regulator 7 are electrically connected to the control board 8.

[0035] The control board 8 receives the illuminance value from the light sensor 6 and, based on the required optimal illuminance value of the online near-infrared moisture meter 16, controls the lamp brightness of the supplementary lighting component 5 through the dimmer 7 to reach the optimal illuminance value, thereby achieving the best and most stable illuminance conditions.

[0036] The side wall of the housing 1 has a third opening that communicates with the installation chamber 12. A door panel 14 for closing the installation chamber 12 is detachably connected to the third opening, so that the installation chamber 12 can be closed to prevent damage to the internal components, and the installation chamber 12 can be opened to repair or replace the components.

[0037] In this embodiment, the edge of the third opening is provided with several second threaded holes. The door panel 14 is connected to the edge of the third opening by bolts. Several bolts corresponding to the second threaded holes pass through the door panel 14 and are threadedly connected to the second threaded holes, thereby realizing the detachable connection of the door panel 14.
