Description

A real-time monitoring device for the stacking height of tobacco storage containers and a tobacco spreading crane device including the same. Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a real-time monitoring device for the stacking height of tobacco storage cabinets and a tobacco spreading crane device including the same. Background Technology

[0002] In the cigarette production process, monitoring the material level in the cigarette storage cabinet and buffer cabinet plays a crucial role in ensuring the quality, safety, and stable operation of the cigarette production process.

[0003] Traditional material stack height monitoring mainly uses mechanical contact rod-type detection devices, which determine the height by triggering a signal through contact with the material. However, such mechanical structures are prone to wear and tear from prolonged contact with materials, leading to decreased detection accuracy and making them unsuitable for the structural differences of various storage tank types.

[0004] Although non-contact detection technologies based on ultrasound or lidar are becoming increasingly mature, existing stockpile height monitoring technologies still have significant shortcomings:

[0005] Firstly, existing monitoring devices are mostly installed using a rigid fixing method, directly fixed to the auxiliary material trolley frame. However, the trolley generates continuous vibration during reciprocating operation, and the rigid connection is prone to sensor displacement or damage. Traditional monitoring devices lack vibration damping measures and cannot effectively offset vibration, thus affecting the stability and detection accuracy of the detection components;

[0006] Secondly, the stockpile shapes vary significantly between different types of storage tanks, and existing detection devices typically use a fixed-angle installation mode, lacking a flexible angle adjustment mechanism. When the storage tank structure is changed, manual disassembly and reassembly are required, affecting production efficiency.

[0007] Therefore, there is an urgent need to develop a real-time monitoring device for the stacking height of tobacco storage bins that has high environmental adaptability and can stably maintain the detection angle, in order to meet the precise detection needs of intelligent production in the tobacco industry. Summary of the Invention

[0008] This invention addresses the shortcomings of existing technologies by developing a real-time monitoring device for the stacking height of tobacco storage containers and a tobacco spreading trolley device including the device. This invention enhances the dust penetration capability of millimeter-wave radar, reduces the impact of vibration by setting up multiple shock-absorbing structures, and configures an early warning device to realize real-time alarm for abnormalities, thereby effectively improving the accuracy, stability and real-time performance of monitoring.

[0009] The technical solution to the technical problem solved by this utility model is as follows:

[0010] This application provides a real-time monitoring device for the stacking height of tobacco storage cabinets, located on both sides of the auxiliary material trolley, including a base, an adjustment frame, and a detection component;

[0011] The adjustment frame includes a first link and a second link. One end of the first link is hinged to the outside of the base via a first damping shaft, and the other end is hinged to the second link located below it via a second damping shaft. The other end of the second link is hinged to the detection component via a third damping shaft.

[0012] The detection component includes a millimeter-wave radar and a bracket hinged to the second link, the bracket being connected to the millimeter-wave radar via a shock-absorbing spring;

[0013] A shock absorber is provided on the inner side of the base, and the shock absorber abuts against the side of the material laying trolley. The base is connected to the material laying trolley.

[0014] As an improvement to the above solution, a third link is connected to one side of the bracket, and the third link is hinged to the second link via a third damping shaft.

[0015] As an improvement to the above solution, the shock absorber is a spring rubber shock absorber, and the base is fixed to both sides of the auxiliary material trolley by fixing bolts.

[0016] As an improvement to the above solution, a rubber damping rod is provided on the first connecting rod. One end of the rubber damping rod is connected to the first connecting rod, and the other end is bent and extended to pass through the second connecting rod. The rubber damping rod and the second connecting rod form a sliding fit.

[0017] As an improvement to the above scheme, the millimeter-wave radar adopts a frequency-modulated continuous wave radar.

[0018] As an improvement to the above solution, the millimeter-wave radar operates at a frequency of 24 GHz and has a wavelength of 11.4 mm. The installation height of the millimeter-wave radar is adapted to the height of the storage cabinet, and the detection range covers the entire height of the storage cabinet.

[0019] As an improvement to the above solution, the millimeter-wave radar is connected to an early warning device.

[0020] As an improvement to the above solution, the warning device includes a warning light and a sirens.

[0021] This application also provides a tobacco material spreading trolley device, including the tobacco storage tank stacking height real-time monitoring device as described in any of the above claims and a spreading trolley. The spreading trolley includes a conveyor belt and a frame. The frame is installed on the side of the conveyor belt. The base is fixedly installed on the frame by fixing bolts. The tobacco storage tank stacking height real-time monitoring device is symmetrically arranged on both sides of the conveyor belt.

[0022] Compared with existing technologies, the above solution has the following advantages or beneficial effects:

[0023] This utility model discloses a real-time monitoring device for the stacking height of cigarette storage cabinets. Through multiple shock absorption measures, including the spring rubber damper on the base, the rubber damping rod on the adjusting frame, and the damping spring on the detection component, it effectively counteracts vehicle vibrations and ensures stable operation of the detection component. The damping shaft hinge structure of the adjusting frame allows for flexible adjustment and stable maintenance of the detection angle. Millimeter-wave radar provides excellent dust penetration and suitable resolution. An early warning device can issue timely alarms.

[0030] Example 1

[0031] Referring to Figures 1-3, this embodiment provides a real-time monitoring device C for the stacking height of tobacco storage containers, which is installed on both sides of the auxiliary material trolley, specifically on both sides of the conveyor belt A of the material spreading trolley. The real-time monitoring device C for the stacking height of tobacco storage containers in this embodiment includes a base 1, an adjustment frame, and a detection component 8.

[0032] The adjusting frame includes a first connecting rod 2 and a second connecting rod 3. One end of the first connecting rod 2 is hinged to the outside of the base 1, and the other end is hinged to the second connecting rod 3. The other end of the second connecting rod 3 is hinged to the detection component 8, and the second connecting rod 3 is hinged below the first connecting rod 2. The detection angle of the detection component 8 is adjusted by the adjusting frame to adapt to different types of leaf storage cabinets, stem storage cabinets, stem and wire storage cabinets, and wire storage cabinets. The installation height of the detection component 8 is adapted to the height of the storage cabinet, and the detection range covers the entire height of the storage cabinet.

[0033] Furthermore, the first connecting rod 2 is hinged to the base 1 via the first damping shaft 5, the first connecting rod 2 and the second connecting rod 3 are hinged via the second damping shaft 6, and the second connecting rod 3 is hinged to the detection component 8 via the third damping shaft 7. This hinged connection via damping shafts allows the adjusting frame to flexibly adjust the detection angle of the detection component 8. While providing the hinged rotation function, the damping shafts also generate a certain damping force, ensuring that the adjusting frame can maintain a stable position after being adjusted to a suitable angle. This prevents changes in the detection angle due to factors such as vehicle vibration, ensuring that the detection component 8 always monitors the material stack height at a suitable angle.

[0034] The detection assembly 8 includes a millimeter-wave radar 81 and a bracket 82. The detection end of the millimeter-wave radar 81 faces the material-laying trolley. A third link 4 is connected to one side of the bracket 82, and the third link 4 is connected to the second link 3 via a third damping shaft 7, thereby adjusting the angle of the millimeter-wave radar 81. The other side of the bracket 82 is fixedly connected to the millimeter-wave radar 81 via a shock-absorbing spring 83. The shock-absorbing spring 83 can absorb the energy transmitted to the millimeter-wave radar 81 by the trolley vibration, reduce the impact of vibration on the millimeter-wave radar 81, and protect the millimeter-wave radar 81, enabling it to work stably in a vibrating environment.

[0035] The millimeter-wave radar 81 employs frequency-modulated continuous wave radar to ensure adequate dust penetration capability. Even in dusty environments like smoke storage tanks, it can accurately detect the stack height, avoiding dust interference with the detection results and improving reliability. Furthermore, the millimeter-wave radar 81 operates in the 24GHz band with a wavelength of 11.4mm. This frequency band selection balances penetration and resolution, ensuring the millimeter-wave radar 81 has excellent dust penetration capability. The installation height of the millimeter-wave radar 81 is adapted to the height of the storage tank, and its detection range covers the entire height of the tank.

[0036] The millimeter-wave radar 81 is connected to an early warning device. When the millimeter-wave radar 81 detects an abnormal material stacking height, the early warning device will issue an alarm to the staff. The early warning device includes an alarm light and an alarm bell. The alarm light flashes and the alarm bell sounds, alerting the staff through both visual and auditory means. This allows the staff to promptly detect abnormal material stacking heights and take appropriate measures to ensure quality, safety, and stable operation during the container unloading process.

[0037] In this embodiment of the utility model, shock absorbers are respectively provided on the four corners of the inner side of the base 1. The shock absorbers are spring rubber shock absorbers 9. The base 1 is fixed to both sides of the auxiliary material trolley by fixing bolts 11. The spring rubber shock absorbers can effectively offset the vibration generated during the reciprocating motion of the trolley, reduce the impact of vibration on the detection component 8, and ensure the stability and accuracy of the detection.

[0038] In this embodiment of the invention, a rubber damping rod 10 for auxiliary vibration reduction is provided on the first connecting rod 2. One end of the rubber damping rod 10 is fixedly connected to the first connecting rod 2, and the other end is bent and extended through the second connecting rod 3. The rubber damping rod 10 can assist in vibration reduction, further reducing the impact of the material laying trolley vibration on the adjusting frame and the detection component 8, improving the vibration resistance of the entire device, and ensuring the normal operation of the detection component 8.

[0039] When the second connecting rod 3 rotates around the second damping shaft 6, the angle of the detection component 8 can be finely adjusted. Since one end of the rubber damping rod 10 is fixedly connected to the first connecting rod 2 and the other end passes through the second connecting rod 3, the rotation of the second connecting rod 3 will apply a force to the rubber damping rod 10, causing its bending angle to change slightly. At the same time, the rubber damping rod 10 can slide within the through hole passing through the second connecting rod 3. This change is determined by the characteristic that one end of the rubber damping rod 10 is fixed and the other end moves with the second connecting rod 3. During vibration, the rubber damping rod 10 will absorb some of the vibration energy through its own deformation, further assisting the device in damping vibration.

[0040] Example 2

[0041] Referring to Figure 3, this embodiment provides a tobacco material spreading trolley device, including any of the tobacco storage cabinet stacking height real-time monitoring devices C in Embodiment 1 above and a spreading trolley. The spreading trolley includes a conveyor belt A and a frame B. The frame B is installed on the side of the conveyor belt A. The base 1 of the real-time height monitoring device is fixedly installed on the frame B by fixing bolts 11, so that the entire device is symmetrically installed on both sides of the conveyor belt A, so as to detect the height of the tobacco storage cabinet and buffer cabinet in real time during the spreading process.

[0042] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
