[0002] Tobacco, food, chemical industry, etc. need to conduct real-time quality inspection of materials in the production process. Take tobacco as an example. Tobacco belongs to the family of tubular flowers. Annual or limited perennial herb , slightly lignified at the base. Inflorescence terminal, conical, multi-flowered; capsule ovate or oblong, about the same length as the persistent calyx. Flowering and fruiting in summer and autumn. Mainly distributed in South America, South Asia, and China. Tobacco stems are the coarse and hard veins of tobacco leaves, accounting for about 25-30% of the leaf weight. Tobacco stems are a by-product of the tobacco industry and are currently mostly discarded. my country is a major tobacco producer, and hundreds of thousands of tons of tobacco stem resources are discarded every year, which not only causes environmental pollution, but also wastes natural resources. Studies have shown that the types of components contained in tobacco stems are basically the same as those in tobacco leaves.

[0003] At present, the sampling and testing of tobacco stems is mainly carried out manually by sampling, weighing and testing, and the weight of the tobacco stems is weighed and recorded, which is a cumbersome operation. Summary of the invention

[0004] In view of this, the present invention provides an automatic material weighing and detection device and method to solve the problem in the prior art that tobacco stem sampling and detection is mainly carried out manually by sampling, weighing and recording the tobacco stems, which is a cumbersome operation.

[0007] In this technical solution, it should be noted that the shell is a sheet metal shell, the bottom plate of the shell is connected to the screw holes below the shell through the through holes on the plate, and the shell is provided with an industrial computer placement position, a power switch position, a circular network port placement port, There are five electrical component placement ports, including a USB placement port and an industrial computer switch placement port. A camera is provided inside the shell for placing and observing the image acquisition work during the weighing process, and transmitting it back to the industrial computer for recording; a sheet metal door is provided on one side of the shell, and the sheet metal door is installed on the shell through a hinge, and a circular push-type lock hole is left on the sheet metal door to install a circular push-type lock; in this scheme, when the tobacco stems pass through the feeding shell and need to be sorted, the industrial computer controls the valve device to close the first channel, and the tobacco stems above flow into the weighing device through the second channel. When the time required for collection is reached, the industrial computer controls the valve device to open the first channel and close the second channel, and the tobacco stems flow into the collecting hopper through the first channel. At this time, the weighing device has the tobacco stems collected in this cycle, which are weighed and the data is recorded. After the recording is completed, the material in the weighing device is taken out to facilitate the weighing of the next cycle.

[0008] Preferably, the first channel and the second channel are interconnected, and the valve device comprises a partition and a moving component, and the moving component is used to drive the partition to move so as to close the first channel or the second channel.

[0009] In this technical solution, it should be noted that the first channel and the second channel are two channels connected to each other, and the tops of the two channels have feeding ports. Materials can be transported to the first channel or the second channel by feeding materials from the feeding ports, and a silo can be connected above the feeding ports.

[0010] Preferably, the first channel is arranged vertically, and the second channel is inclined at one side of the first channel and is connected to the first channel; one end of the partition is rotatably connected to the connection between the first channel and the second channel through a rotating shaft; the moving component includes a first motor arranged outside the feed shell and electrically connected to the industrial computer, the output end of the first motor is fixedly connected to the rotating shaft, and the first motor drives the rotating shaft to rotate so that the partition closes the first channel or the second channel.
