Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of product weight detection, and in particular relates to a material detection device capable of automatic weighing. Background Art
[0002] Tobacco, food, and chemical industries require real-time quality inspection of materials during production. Take tobacco, for example. It belongs to the Solanaceae family, a family of tubular flowers. It is an annual or limited perennial herb with a slightly lignified base. Its inflorescence is terminal, conical, and multiflorous. The capsule is ovate or oblong, approximately the same length as the persistent calyx. Flowering and fruiting occur in summer and autumn. It is primarily distributed in South America, South Asia, and China. Tobacco stems, the coarse, hard veins of tobacco leaves, account for approximately 25-30% of the leaf weight. Tobacco stems are a byproduct of the tobacco industry and are currently mostly discarded. Research has shown that the components of tobacco stems are largely consistent with those in tobacco leaves.
[0003] At present, the sampling and testing process of tobacco stems is mainly carried out manually by sampling, weighing and testing, and the tobacco stems are weighed and recorded, which is a cumbersome operation. Utility Model Content
[0004] In view of this, the present invention provides a material detection device that can automatically weigh, so as 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 relatively cumbersome operation.
[0005] The technical solutions adopted in this utility model are as follows:
[0006] A material detection device capable of automatic weighing comprises a shell, wherein a weighing device and a collecting hopper are provided in the shell, a feed shell is connected to the shell, the feed shell has a first channel and a second channel respectively connected to the collecting hopper and the weighing device, a valve device is further provided in the feed shell, the valve device is used to control the opening and closing of the first channel and the second channel; and an industrial computer is also included, which is electrically connected to the valve device and the weighing device respectively.
[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 placement ports for electrical components, including a USB placement port and an industrial computer switch placement port. A camera is provided inside the shell for observation of image acquisition during the weighing process, and the image is transmitted back to the industrial computer for recording. A sheet metal door is provided on one side of the shell, which is installed on the shell through a hinge. A circular push-type lock hole is left on the sheet metal door to install a circular push-type lock. In this solution, when tobacco stems pass through the feed 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 for the next weighing cycle.
[0008] Preferably, the first channel and the second channel are communicated with each other, and the valve device includes a partition and a moving component, and the moving component is used to drive the partition to move 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 there is a feed port at the top of the two channels. The material can be transported to the first channel or the second channel by unloading from the feed port, and a silo can be connected above the feed port.
[0010] Preferably, the first channel is arranged vertically, and the second channel is arranged obliquely on 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 control 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.
[0011] In this technical solution, it should be noted that the angle between the first channel and the second channel is an acute angle, and the first motor can be used to drive the rotation to close the first channel or the second channel; in this solution, when the partition closes the first channel or the second channel, there is a gap between the end of the partition and the first channel and the second channel, which can prevent the partition from generating frictional contact with the two channels during rotation. In order to prevent material from leaking from the gap, inclined plates are provided above the first channel and the second channel. The inclined plates are used to block the gap to prevent material from leaking from the gap when a channel is closed.
[0012] Preferably, the collecting hopper is located below the first channel, the weighing device is located on one side of the first channel, and the weighing device is between the second channel and the collecting hopper.
[0013] In this technical solution, it should be noted that since the aggregate hopper is located below the first channel, the weighing device is located on one side of the first channel, and the weighing device is between the second channel and the aggregate hopper, the structure of the entire device is compact, which improves the utilization rate of the space inside the shell; the specific principle is: since the weighing device is above the aggregate hopper and located on one side of the second channel, the projections of the feed shell and the weighing device from top to bottom are basically projected onto the aggregate hopper, saving space in the width direction of the shell.
[0014] Preferably, the bottom of the housing is provided with a foot, which includes a foot pad and a screw, wherein the screw is fixed on the top of the foot pad and slides through the housing. A nut is screwed on the screw, and the nut is located below the housing to support the housing.
[0015] In this technical solution, it should be noted that the height of the shell can be adjusted by setting the feet. Specifically, the height of the nut on the screw can be adjusted by rotating the nut, thereby achieving the height of the shell supported by the nut.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0017] 1. In the present invention, the opening and closing of the first channel and the second channel are controlled by the valve device, so that tobacco stems can be sampled accurately within the set time, effectively avoiding errors caused by human operation and improving the accuracy of detection.
[0018] 2. In the present invention, the first motor drives the partition to automatically switch channels, automatically guiding the tobacco stems from the second channel to the weighing device without manual intervention, thereby improving operating efficiency and system automation level.
[0019] 3. In this utility model, after each sampling is completed, the weight of the tobacco stems flowing into the weighing hopper can be recorded in real time. This data can be used to further analyze the quality of raw materials during the production process, thereby helping to optimize the production process;
[0020] 4. In the present invention, since the weighing device is above the collecting hopper and located on one side of the second channel, the projections of the feed shell and the weighing device from top to bottom are basically projected onto the collecting hopper, saving space in the width direction of the shell.
