Description

Technical Field

[0001] This utility model belongs to the field of tobacco production technology, and in particular relates to a tobacco leaf density monitoring device for tobacco leaf threshing machines. Background Technology

[0002] The threshing process is a crucial step in tobacco processing. The density of the tobacco leaves dropped by the threshing machine represents the machine's threshing efficiency. A reasonable density ensures both efficiency and quality. Currently, the tobacco density is monitored manually. If the density is too high or too low, the machine's control system is adjusted to maintain a reasonable range. However, this method relies on subjective judgment, which can lead to inaccuracies. Furthermore, it requires constant manual observation, and with six threshing units per machine, this necessitates significant manual effort and increases labor costs. Therefore, this paper proposes a tobacco density monitoring device for tobacco threshing machines.

[0003] For example, Chinese patent CN221996813U discloses a tobacco leaf density monitoring device for a tobacco threshing machine, comprising a device body, a camera unit, a lighting source unit, an air curtain / air knife unit, and a support swing arm unit. The device body contains all of these units.

[0004] This patent has the following problems:

[0005] Existing technologies are inconvenient for uniformly detecting light density on both sides of the leaves, and obstruction can easily occur during tobacco density monitoring, reducing the accuracy of density detection. Furthermore, existing technologies do not allow for quick removal of tobacco leaves after density testing, thus reducing the convenience of leaf extraction. Therefore, we propose a tobacco leaf density monitoring device for tobacco threshing machines in tobacco production. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a tobacco leaf density monitoring device for tobacco leaf threshing machines, thereby improving the accuracy of tobacco leaf density detection and enhancing the convenience of tobacco leaf extraction after density detection.

[0007] In view of this, the present invention provides a tobacco leaf density monitoring device for a tobacco threshing machine, comprising a transparent outer box, and further comprising: lighting mounting plates fixedly installed at both ends of the transparent outer box, lighting lamp plates being installed through the interior of the lighting mounting plates, detection frames fixedly installed on both sides of the lighting mounting plates, line scanning cameras fixedly installed between the interior of the detection frames, a density detector fixedly installed at one end of each line scanning camera, and a pull-up transparent frame movably installed inside the transparent outer box, a pull-up plate fixedly installed on the top of each pull-up transparent frame, and a handle groove being provided through the interior of each pull-up plate.

[0008] Based on the above structure, two lighting mounting plates are fixedly installed at both ends of the transparent outer box. The two lighting plates then illuminate the tobacco leaves inside the transparent outer box. Line scanning cameras on both sides transmit the images of the tobacco leaves inside the transparent outer box in real time. Next, density detectors on both sides measure the density of the tobacco leaves inside the transparent outer box, enabling uniform illumination density detection on both sides of the leaves, thereby improving the accuracy of tobacco density detection. Then, the tobacco leaves whose density needs to be tested are placed using a lifting transparent frame. Finally, a handle groove allows users to easily lift the tested tobacco leaves from inside the transparent outer box, enabling quick removal of the tobacco leaves after density testing, thus improving the convenience of extracting the tobacco leaves after density testing.

[0009] Preferably, a bottom mounting plate is fixedly installed at the bottom of the transparent outer box, and side mounting strips are fixedly installed on both sides of the bottom mounting plate.

[0010] Preferably, both sides of the side mounting strip are fixedly equipped with lifting handles, and the lifting handles are all made of plastic.

[0011] Preferably, an anti-slip pad is fixedly installed on the bottom of the bottom mounting plate, and an observation mounting plate is fixedly installed on the surface of the anti-slip pad.

[0012] Preferably, the observation mounting plate is made of plastic, and a display is fixedly mounted on the top of the observation mounting plate.

[0013] Preferably, a control board is fixedly mounted on one side of the display, and the control board is made of plastic.

[0014] Preferably, a control button is fixedly installed on the surface of the control panel, and a power socket is fixedly installed at the bottom of the control button.

[0015] The beneficial effects of this utility model are:

[0016] 1. This tobacco leaf density monitoring device for a tobacco threshing machine unit is fixedly installed at both ends of a transparent outer box using two lighting mounting plates. The two lighting plates then illuminate the tobacco leaves inside the transparent outer box. Line scanning cameras on both sides transmit the images of the tobacco leaves inside the transparent outer box in real time. Density detectors on both sides then detect the density of the tobacco leaves inside the transparent outer box. This device can detect the uniform light density on both sides of the leaves, and it is less likely to cause obstruction during tobacco leaf density monitoring, thereby improving the accuracy of tobacco leaf density detection.

[0017] 2. This tobacco leaf density monitoring device for tobacco production threshing machine unit allows users to place the tobacco leaves whose density needs to be tested in a transparent frame by lifting it. Then, the handle groove makes it easy for users to lift the tested tobacco leaves out of the transparent outer box, which can quickly remove the tobacco leaves after density testing, thereby improving the convenience of tobacco leaf extraction after density testing.
