Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a material blockage early warning device. Background Technology
[0002] In the tobacco processing industry, belt conveyors are widely used in various key stages due to their efficient and stable material conveying characteristics. Storage feeders or temporary storage cabinets are typically installed before important processes such as leaf conditioning, drying, and flavoring. These devices play a crucial role, storing a portion of the material in each production batch, providing operators and maintenance personnel with time to handle batch malfunctions, thus effectively ensuring the continuity and stability of production in critical processes. Theoretically, as long as blockages can be detected and addressed promptly between functional areas or between the storage feeders or temporary storage cabinets leading from the previous process to the critical process, the continuity of production in critical processes can be ensured, significantly reducing downtime and material interruptions caused by blockages.
[0003] However, in actual production practice, many thorny problems arise. High-level conveying equipment, conveying equipment between functional areas, and conveying equipment located in blind spots are difficult to monitor in real time due to their special locations. This often leads to the inability to detect material blockages in a timely manner, resulting in multi-point and large-scale blockages. Even with significant investment of manpower and time to address the blockage problem, clearing the production line before the material in the storage cabinet or feeder is emptied remains extremely difficult, inevitably leading to shutdowns and material shortages in critical processes, causing serious negative impacts on production.
[0004] To address the problem of material blockage, the industry currently employs various anti-blocking devices, commonly including through-beam phototube detection, mirror-reflection phototube detection, and rotary paddle level gauge detection. However, these devices have revealed numerous drawbacks in practical use. For example, through-beam and mirror-reflection phototube detection are easily affected by external environmental factors such as dust and changes in light, leading to a high false alarm rate. This not only increases the workload of operators but may also disrupt normal production. While rotary paddle level gauge detection is relatively stable to a certain extent, its installation and operation are extremely inconvenient, requiring significant manpower and time for installation and subsequent maintenance. In conclusion, existing anti-blocking devices can no longer meet the demands of efficient and stable operation in tobacco processing, necessitating a new and more reliable anti-blocking technology to solve these problems.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0036] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0037] like Figures 1-7As shown, this embodiment provides a material blockage early warning device, which mainly includes a first connecting member 1, a sensing element 2, a first attracting element 3, a second attracting element 4, and a blocking element 5. The first connecting member 1 is provided with two fixing holes, which can be used to fix the first connecting member 1 to the discharge cover of the conveying equipment at the anti-blockage position by bolts, screws, etc. The sensing element 2 is disposed on the first connecting member 1, the first attracting element 3 is disposed on the sensing element 2, and the second attracting element 4 can attract or separate from the first attracting element 3. The blocking element 5 is connected to the second attracting element 4. In this embodiment, the sensing element 2 can be an inductive proximity switch, a capacitive proximity switch, a Hall effect proximity switch, a photoelectric proximity switch, etc. In this embodiment, a Hall effect proximity switch is selected. In addition, the first attracting element 3 is a metal nut, the material of which can be iron, steel, nickel alloy, etc. In this embodiment, a steel nut is selected. The second attracting element 4 can be an electromagnetic... Iron, or a magnet, can be used. In this embodiment, the second attracting element 4 is a magnet. When the material is being conveyed normally in the conveyor, the blocking element 5 is in its initial position. At this time, the first attracting element 3 and the second attracting element 4 are attracted together. The sensing element 2 has a first sensing signal and is in a normal sensing state. The sensing element 2 will not send an alarm signal to the early warning system, and the equipment is operating normally. When the material is too high and there is a risk of blockage, the accumulated material will push the blocking element 5, causing the second attracting element 4 to disconnect from the first attracting element 3. When the sensing element 2 senses this change, it has a second sensing signal. The sensing element 2 will transmit the second sensing signal to the early warning system. The early warning system will immediately stop the operation of the conveying equipment and the equipment in the material direction, and at the same time issue an alarm signal. After receiving the alarm signal, the operators and maintenance personnel can go to the site as soon as possible and deal with it in a timely manner, so that the equipment can resume production as soon as possible and ensure production efficiency.
[0038] Preferably, in order to facilitate the assembly of the material blockage early warning device, the sensing element 2 is provided with external threads, and the first connecting element 1 and the first suction element 3 are both provided with internal threads. The first connecting element 1 and the first suction element 3 are connected to the sensing element 2 by threads. The threaded connection method can make it easier to disassemble and assemble the material blockage early warning device, and it is less likely to cause connection failure during the use of the device.
[0039] Preferably, such as Figures 1-2As shown, the material blockage warning device also includes a locking member 6. The locking member 6 is provided with an internal thread and is threadedly connected to the sensing member 2. The locking member 6 is located above the first suction member 3 at the position where it is threadedly connected to the sensing member 2, and the first suction member 3 abuts against the locking member 6. The locking member 6 can lock and fix the position of the first suction member 3, ensuring that the first suction member 3 is stably installed on the sensing member 2. This allows the second suction member 4 to be stably attracted to the first suction member 3, and prevents the attraction between the second suction member 4 and the first suction member 3 from becoming unstable due to changes in the position of the first suction member 3, which could cause false warnings, abnormal production stoppages, and affect production efficiency.
[0040] Preferably, such as Figure 7 As shown, the material blockage warning device also includes a second connector 7. The second suction member 4 and the blocking member 5 are both disposed on the second connector 7. The second connector 7 realizes the connection between the second suction member 4 and the blocking member 5, thereby making the connection between the second suction member 4 and the blocking member 5 more stable and increasing the convenience of its connection.
[0041] Preferably, such as Figure 5 As shown, the second connector 7 is provided with a receiving groove 71, at least a portion of the second suction member 4 is located in the receiving groove 71, a connecting hole is provided on the groove wall of the receiving groove 71, a fastening hole is provided at the corresponding position of the second suction member 4, a fastener passes through the connecting hole and is fastened to the fastening hole, and an internal thread is also provided below the second connector 7, and the blocking member 5 is connected to the second connector 7 by the thread.
[0042] Preferably, such as Figures 6-7 As shown, the blocking member 5 includes a blocking part 51 and an adjusting part 52 connected in a T-shape. Both ends of the adjusting part 52 are provided with external threads. One end of the adjusting part 52 is threadedly connected to the blocking part 51, and the other end is threadedly connected to the second connecting member 7. The adjusting part 52 can adjust the height of the blocking part 51 by adjusting the length of its screw-in into the blocking part 51, so that the blockage warning device can provide warnings for blockages at different warning heights, thus expanding the applicability of the device. The height of the blocking part 51 can be adjusted according to different warning requirements. The blocking part 51 is plate-shaped, and it can be rectangular, circular, triangular, etc. In this embodiment, the blocking part 51 is rectangular. This utility model does not limit the shape of the blocking part 51, but blocking parts 51 of different shapes are all within the protection scope of this utility model.
[0043] Preferably, such as Figure 7As shown, the blocking component 5 also includes two locking nuts 53. The two locking nuts 53 are respectively threaded to the connection between the adjusting part 52 and the blocking part 51 and the connection between the adjusting part 52 and the second connecting component 7. The locking nuts 53 can make the connection between the blocking part 51 and the adjusting part 52 and the blocking component 5 and the second connecting component 7 more stable and reliable, preventing the blocking part 51 or the blocking component 5 as a whole from falling off, thereby causing the blockage warning device to fail.
[0044] Preferably, the adjusting part 52 is a telescopic rod, which can more conveniently adjust the height of the blocking part 51 without loosening the locking nut 53 to tighten the blocking part.
[0045] Preferably, such as Figures 1-2 As shown, the material blockage warning device also includes an anti-detachment component 8. The anti-detachment component 8 is a flexible component, which can be made of nylon rope, chain, etc. One end of the anti-detachment component 8 is connected to the first connecting component 1, and the other end is connected to the second connecting component 7. The anti-detachment component 8 effectively prevents the second connecting component 7, the second connecting component 4, and the blocking component 5 from falling into the material when the second suction component 4 and the first suction component 3 separate due to the material pile-up. This ensures the safety of equipment operation and the quality of the material, saves the operator time in searching for fallen objects in the material, and improves work efficiency.
[0046] Installation steps of the material blockage early warning device provided by this utility model:
[0047] First, determine the installation position of the first connector 1 on the discharge cover of the tobacco conveyor, and use screws and nuts to fix the first connector 1 on the discharge cover to ensure that the first connector 1 is installed firmly and will not shake or shift during the operation of the equipment.
[0048] The sensor 2 is threaded into the first connector 1. Then, the locking member 6 is installed on the sensor 2, and then the first suction member 3 is installed on the sensor 2, so that the first suction member 3 is aligned with the sensing surface of the sensor 2. The locking member 6 is tightened to abut against the first suction member 3 to prevent the first suction member 3 from loosening during the operation of the equipment.
[0049] Install the second suction member 4 into the receiving groove 71 of the second connector 7, and fix the second suction member 4 in the receiving groove 7 with fasteners. Thread the two ends of the adjusting part 52 to the second connector 7 and the blocking part 51 respectively, and lock them at the connection with the locking nut 53. Adjust the height of the blocking part 51 according to actual needs.
[0050] Connect one end of the anti-detachment component 8 to the first connector 1 and the other end to the second connector 7, while ensuring that the anti-detachment component 8 is securely connected.
[0051] This utility model patent provides a material blockage early warning device that effectively solves the material blockage problem that easily occurs in tobacco conveyors during production through reasonable structural design and ingenious working principle.
