[0040] Before describing the tobacco storage cabinet discharging device of the embodiment of the utility model, its application scenario is described. The discharging device can be applied to tobacco storage cabinets, and can also be used in other devices that need to calculate the material discharging amount, such as grain storage warehouses, chemical production equipment, etc.

[0041] Next, take the application of the discharge device in tobacco storage cabinet as an example, combined with Figure 1-Figure 3 The utility model describes a tobacco storage cabinet discharging device.

[0042] refer to Figure 1 As shown, the tobacco storage cabinet discharging device of the embodiment of the utility model includes a storage box 100, a conveying device 200, a detection device 300 and a processor (not shown in the figure), the storage box 100 is used to store materials; the conveying device 200 is installed at the bottom of the storage box 100, the conveying device 200 is connected with the discharge port 110 of the storage box 100, and the conveying device 200 is provided with a positioning part 210; the detection device 300 is located on the conveying path of the conveying device 200, and is used to detect the number of times the positioning part 210 passes through the detection device 300; the processor is configured to determine the discharge amount of the material according to the number of times the positioning part 210 passes through the detection device 300 and the single discharge amount.

[0043] According to the tobacco storage cabinet discharging device of the embodiment of the utility model, the detection device 300 can detect in real time the number of times the positioning part 210 passes through the detection device 300. Combined with the single discharge amount, not only can the discharge amount of the material be accurately calculated to ensure that the discharge amount each time meets expectations and reduce waste and excessive discharge problems, but also, by detecting the discharge amount through the positioning part 210 of the conveying device 200, it is possible to save the need to set up an additional weighing device (such as a belt scale), and the method of measuring the discharge amount is simple and efficient.

[0044] It should be noted that the positioning portion 210 may be a rectangular body, a disc body, or a sphere, and the shape of the positioning portion 210 is not limited herein.

[0045] The processor may be a multiplier, an adder, etc. Taking the processor as a multiplier as an example, the processor determines the total discharge amount by the number of times the positioning part 210 passes and the single discharge amount. Taking the processor as an adder as an example, the processor calculates the total discharge amount by detecting and superimposing the single discharge amount. The single discharge amount may be obtained by pre-measurement, for example, the discharge amount when the positioning part passes once may be pre-measured, and the discharge amount may be stored in the processor.

[0046] Of course, the processor can also be a program with multiplication and addition functions.

[0047] It should be noted that the conveying device is arranged at the bottom of the storage box. Taking the conveying device as a belt as an example, the surface of the belt is located inside the storage box and is in direct contact with the material in the storage box. It can be understood that the material entering the storage box will directly fall on the belt for storage, and the belt is connected to the discharge port. When the material needs to be discharged, the belt moves, thereby driving the material to move to the material port to realize the discharge.

[0048] refer to Figure 2 and Figure 3 As shown, the conveying device 200 includes a bracket 220 and a transport structure 230, the transport structure 230 is connected to the driving wheel 241 and the driven wheel 242, the transport structure 230 bypasses the driving wheel 241 and the driven wheel 242, the driving wheel 241 and the driven wheel 242 are rotatably connected to the bracket 220, the first surface 231 of the transport structure 230 is used to transport materials, the second surface 232 of the transport structure 230 is facing away from the first surface 231, and the detection device 300 is connected to the bracket 220 and faces the first surface 231 or the second surface 232. The detection device 300 is arranged on the bracket 220, which can facilitate the detection device 300 to detect the number of times the positioning part 210 passes, thereby improving the detection accuracy.

[0049] Among them, reference Figure 3As shown, the detection device 300 can be oriented toward the first surface 231 or the second surface 232, and the detection device 300 can detect the positioning portion 210 passing by. It can be understood that the first surface 231 is the outer side of the detection device 300, and the outer side is used to transport materials; the second surface 232 is the inner side of the detection device 300, and the inner side is in contact with the driving wheel 241 and the driven wheel 242, and the inner side is in contact with the driving wheel 241 and the driven wheel 242. Figure 3 It can be seen that in the up and down direction, the second surfaces 232 are arranged at intervals to ensure that the driving wheel 241 and the driven wheel 242 can be wound around. Preferably, the detection device 300 is arranged between the upper and lower second surfaces 232, which can not only protect the detection device 300, prevent the detection device 300 from being directly exposed to the external environment, and extend the service life of the detection device 300, but also reduce interference with the detection device 300, ensure the accuracy of detection, and at the same time, effectively utilize the space of the conveying device 200, save the space for the detection device 300, improve the space utilization rate, and make the structure of the entire device more compact.

[0050] The transport structure 230 includes a transport chain, which is formed by connecting a plurality of chain links in series. Compared with a conveyor belt, the transport chain can provide higher stability and reliability. The connection between the chain links is relatively strong and can bear a larger load. A positioning portion 210 is provided at one end of each chain link. The plurality of positioning portions 210 are arranged at intervals. By adjusting the intervals of the positioning portions 210, the positioning portions 210 can be adapted to materials of different sizes and shapes. The high flexibility enables the transport chain to handle various types of materials. For example, for materials of large size, the intervals of the positioning portions 210 can be set wider; for materials of small size (such as tobacco), the intervals of the positioning portions 210 can be set narrower, so as to better obtain the discharge amount.

[0051] In some embodiments, in combination Figure 4 and Figure 5 The chain link includes a first roller 251, a first chain plate 253 and a second chain plate (the second chain plate is blocked by the first chain plate 253), one end of the first chain plate 253 is hinged to the first roller 251, the other end of the first chain plate 253 is hinged to the second roller 252 of the adjacent chain link, the second chain plate is arranged opposite to the first chain plate 253 and connects the first roller 251 and the second roller 252, and the first roller 251 and the second roller 252 are the positioning part 210. There is a spacing between adjacent rollers, that is, adjacent rollers are arranged at intervals, ensuring that the detection device 300 can intermittently detect the rollers, ensuring that the detection device 300 can stably detect the positioning part 210, and the measurement of the discharge amount is reliable.

[0052] refer to Figure 6As shown, the transport structure 230 may include a transport plate, with rollers connected at both ends of the transport plate. The transport plate contacts the material to transport the material. Adjacent transport plates are connected by a first chain plate 253 and a second chain plate. The first chain plate 253 and the second chain plate ensure the stability of the connection between adjacent rollers, so that the transport plate can accurately move along the transport direction of the conveying device 200. At the same time, since the chain includes a first roller 251, a second roller 252, a first chain plate 253 and a second chain plate, it has good stability and high reliability, which can ensure that the chain links maintain a stable material transportation effect during transportation, reduce the possibility of chain links detaching or loosening, and stabilize the material transportation effect.

[0053] Of course, the transport structure 230 may also include a transport belt, and the transport belt is provided with a plurality of positioning portions 210 , and the plurality of positioning portions 210 are evenly distributed. The transport structure 230 may be arranged according to actual needs.

[0054] It should be noted that one or more positioning parts 210 may be provided. Providing multiple positioning parts 210 can position the material quantity at multiple positions in the conveying direction, thereby achieving more accurate measurement of the material quantity and improving the reliability of the discharge quantity measurement.

[0055] The detection device 300 is described below.

[0056] The detection device 300 includes a magnetic induction sensor. Based on the conveying device 200 driving the positioning part 210 to move relative to the detection device 300, the positioning part 210 passes through the detection device 300, and the detection device 300 outputs a detection signal. It can be understood that the magnetic induction sensor is a non-contact sensor. The magnetic induction sensor does not need to be in direct contact with the positioning part 210, but detects by sensing the change of the magnetic field. During the detection process, it will not cause physical damage or interference to the positioning part 210, avoiding the risk of damage to the positioning part 210 due to contact detection. At the same time, the magnetic induction sensor has a fast response speed, can provide high-precision detection results, reliable detection, and can monitor the movement of the positioning part 210 in real time. When the positioning part 210 passes through the position of the magnetic induction sensor, the magnetic induction sensor is triggered and sends a pulse, indicating that a positioning part 210 passes through. It can also be understood that it means that the positioning part 210 passes once, and the number of times the positioning part 210 passes is detected so that the subsequent processor can determine the discharge amount.

[0057] In some embodiments, the transport structure 230 includes rollers, which are connected to the guide rails of the conveying device 200. In this case, the driving wheel 241 and the driven wheel 242 are connected to the transport structure 230 in a transmission manner so that the transport structure 230 moves, thereby driving the rollers to move in the guide rails. In this case, the rollers may be the positioning part 210, and the rollers 260 are arranged at intervals. The magnetic induction sensor detects the number of times the rollers pass. That is, when the positioning part 210 is a roller, the structure of the transport structure 230 can be fully utilized without adding additional components, thereby simplifying the structure of the overall device and reducing costs.

[0058] Combination Figure 1 The right side of the storage box 100 is the discharge port 110, and the direction from left to right is the storage cabinet discharge direction. The bottom belt rotates clockwise during discharge, and the positioning part 210 of the bottom belt of the storage cabinet is detected by the magnetic induction sensor. The electronic control program of the processor counts, and the electronic control count value is divided by the total number of positioning parts 210 to obtain the discharge percentage, thereby obtaining the material amount.

[0059] The detection device 300 may be a magnetic induction sensor, or other non-contact sensors such as an ultrasonic sensor, a laser sensor, or a photoelectric sensor.

[0060] In some embodiments, the detection device 300 includes a micro switch, and the detection device 300 is triggered to output a detection signal by contacting the contact end of the micro switch with the positioning part 210. It is understandable that the micro switch is a contact detection device 300 with a simple structure and is not prone to failure. The triggering action of the micro switch is sensitive. When the positioning part 210 passes, the micro switch contacts the positioning part 210, and the micro switch outputs a detection signal, which can improve the accuracy of the detection. The micro switch requires a small force or displacement to trigger the output of the detection signal, which helps to protect the positioning part 210 and reduce the possibility of wear. At the same time, the position of the positioning part 210 can also be accurately detected. It is understandable that if the micro switch does not contact the positioning part 210, there will be no detection signal. When the positioning part 210 passes once, the positioning part 210 contacts the micro switch once, and the micro switch outputs a detection signal once, that is, the number of times the positioning part 210 passes once is recorded.

[0061] In some embodiments, the transport structure 230 includes a roller, which is connected to the guide rail of the conveying device 200. At this time, the driving wheel 241 and the driven wheel 242 are connected to the transport structure 230 in a transmission manner, so that the transport structure 230 moves and drives the roller to move in the guide rail. At this time, when the roller passes the micro switch, the micro switch contacts the roller to detect the number of times the roller passes; when the roller leaves the micro switch position, the micro switch resets and prepares to contact the next roller.

[0062] It should be noted that the detection device 300 can be contact type or non-contact type, and can be configured according to specific needs, which is not limited here. The detection device 300 only needs to be able to detect the number of times the positioning portion 210 passes.

[0063] The detection device 300 includes a shell 310 and a detection body 320. The shell 310 is connected to the bracket 220 of the conveying device 200. The detection body 320 is installed in the shell 310. The detection end of the detection body 320 extends out of the shell 310 and faces the conveying device 200. The shell 310, as an external protective layer of the detection body 320, can effectively prevent external objects or impurities from interfering with or damaging the detection body 320, which helps to ensure the detection accuracy of the detection body 320, extend the service life of the detection body 320, and improve the stability and reliability of the detection device 300.

[0064] In some embodiments, the tobacco cabinet discharging device further comprises a driving device 400, the rotating shaft 410 of the driving device 400 is connected to the driving wheel 241 in a transmission manner, a detection component is arranged on the rotating shaft 410 of the driving device 400, the detection component detects the number of rotations of the rotating shaft 410, and the processor is configured to calculate the discharging amount of the conveying device 200 according to the number of rotations of the rotating shaft 410 and the single discharging amount. In this embodiment, the detection component is arranged on the rotating shaft 410, and the detection component can measure the number of rotations of the rotating shaft 410 and output a signal. It can be understood that the conveying length of the conveying device 200 is fixed when the rotating shaft 410 rotates once. When the processor receives the signal output by the detection component, the relationship between the number of rotations and the conveying device 200 (such as the relationship between the number of rotations of the rotating shaft 410 and the length of the conveyor belt) pre-stored by the processor can determine the transport length of the conveying device 200, and then combined with the single discharging amount, the discharging amount of the material is determined, thereby improving the measurement accuracy of the discharging amount.

[0065] Of course, a detection device may be provided on the conveying path of the conveying device 200, and a detection component may be provided on the rotating shaft 410 of the driving device 400, so as to achieve double protection of the metering accuracy of the discharge amount, realize mutual calculation of the discharge amount, and further optimize the metering accuracy of the material amount.

[0066] In this embodiment, the detection component can be an encoder to measure the number of rotations of the rotating shaft 410; it can be an angle sensor to measure the rotation angle of the rotating shaft 410 and measure the conveying length through the rotation angle; it can be a pulse counter to measure the number of rotations by calculating the pulse signal generated by the rotation of the rotating shaft 410.

[0067] In some embodiments, the processor is used to control the conveying speed of the conveying device 200. On the basis that the processor can determine the discharge volume, accurate control and calculation of the discharge volume can be achieved by controlling the conveying speed. By adjusting the conveying speed, not only can the discharge volume be ensured to be within the set range, thereby improving the accuracy and reliability of the production process, but also the efficiency of transportation can be improved.

[0068] refer to Figure 3 As shown, the tobacco storage cabinet discharging device also includes a material scanning device 500 for scanning the material in the storage box 100, and the material scanning device 500 is installed on the top of the storage box 100. In this embodiment, the material scanning device 500 is located on the top of the lifting storage box 100, and can scan the material below, and feed back the terrain elevation of the material below to the processor, that is, the material scanning device 500 can monitor the height of the material in the storage box 100 in real time, and obtain the material storage situation and change situation. The processor combines the terrain elevation data provided by the material scanning device 500 and the information such as the number of times the positioning part 210 passes, and can accurately calculate the material discharge amount, which helps to accurately control the delivery and transportation of materials, and avoid low production efficiency or waste of resources due to insufficient or waste of materials.

[0069] Among them, the material scanning device 500 can adopt a laser scanning device, and the laser scanning device emits a laser 510 downward to scan the material to obtain the material height. The non-contact material scanning device 500 does not need to directly contact the material, thereby avoiding possible contamination or damage to the material. Regarding obtaining the material height, the coordinate system can be pre-stored in the processor, and the processor feeds back the position information of the material to the processor through the laser scanning device, which can determine the position of each point of the material. After the processor calculates, the cross-sectional area of ​​the material is obtained, which can also be understood as obtaining the height of the material stack. The processor, combined with the number of times the positioning part 210 passes through the detection device 300, can improve the metering method of the material discharge amount and make the metering of the discharge amount more accurate.

[0070] In some embodiments, the tobacco storage cabinet discharging device further includes a stirring device, and the storage box 100 is provided with a stirring device, which is installed inside the storage box 100 and located on the top of the conveying device 200. Under the stirring action of the stirring device, the tobacco is fully loosened, ensuring that the tobacco material on the conveying device 200 is uniform, which not only helps to improve the precision and accuracy of determining the discharge amount by detecting the number of times the positioning part 210 passes, but also prevents blockage, prevents the accumulation or agglomeration of tobacco in the storage box 100, and avoids the problem of blockage of the conveying device 200, thereby causing the problem of inaccurate measurement of the discharge amount.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
