Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a tobacco water-based raw material unloading device. Background Technology

[0002] With the development of the tobacco industry, water-based raw materials for tobacco products are being used more and more widely in cigarette production, e-cigarette manufacturing, and other processes. These raw materials are usually in liquid or semi-fluid form, and some also contain volatile and flammable components such as ethanol and propylene glycol, thus placing higher demands on the safety, efficiency, and accuracy of the unloading process.

[0003] Currently, most unloading devices for water-based raw materials used in tobacco products on the market suffer from problems such as limited functionality and insufficient safety. For example, traditional unloading devices often employ a fixed-height design, making it difficult to adapt to different sizes of transport tank trucks, resulting in low loading and unloading efficiency. In terms of safety protection, some devices lack effective leakage monitoring and alarm mechanisms, failing to detect raw material leaks in a timely manner, which can easily lead to safety accidents and environmental pollution. At the same time, protective structures such as guardrails are mostly fixed, resulting in poor flexibility during use, affecting both operational convenience and the inability to fully protect the safety of operators. Furthermore, existing devices also have many shortcomings in details such as anti-static and anti-vibration design, failing to meet the special unloading requirements of water-based raw materials used in tobacco products.

[0004] Therefore, this utility model proposes a water-based raw material unloading device for tobacco products to solve the above problems.

[0047] Specifically, in order to enable simultaneous unloading operations into different pipelines as needed, and to facilitate the adjustment of the discharge volume of each outlet, the discharge pipe 32 has multiple outlets, and a regulating valve 321 is installed near each outlet of the discharge pipe 32.

[0048] The selection of the transfer pump 3 is made by technical personnel based on the actual usage scenario and the type of medium being pumped.

[0049] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0050] Working principle:

[0051] When unloading water-based raw materials for tobacco is required, the vehicle body 1 is first moved to the discharge port of the transport tanker and the power is turned on. Then, the explosion-proof motor 23 drives the lead screw 24 to rotate, causing the lower moving plate 22 to move laterally along the guide rod 211. During this process, the four support rods work together through cross-rotation connection to convert the lateral displacement into the vertical lifting motion of the support box 2, thereby adjusting the height of the support box 2 according to actual needs. This allows the feed pipe 31 to be adjusted to a height that is convenient for docking with the discharge port of the tanker. After docking, the vehicle body 1 is limited. At the same time, the explosion-proof motor 45 is started, causing the horizontal shaft 46 to drive the two transmission gears 44 to rotate through the bevel gear 47 and the rotating shaft 43. The transmission gear 44 at the top of the rotating shaft 43 further drives the toothed plate 42 to slide on the support block 41, thereby enabling the guardrails 4 on the front and rear sides to be quickly unfolded or retracted. At the same time, the safety light curtain 5 is activated.

[0052] During the unloading process, the flow valve 311 on the feed pipe 31 monitors the material flow in real time and controls the start and stop of the material conveying through the shut-off valve 312. The shut-off valve 312 is controlled by electrical control and is linked with the conveying pump 3, that is, the conveying pump 3 and the shut-off valve 312 start and stop synchronously.

[0053] After the conveying pump 3 draws the water-based raw material into the feed pipe 31, it is distributed to multiple discharge ports through the discharge pipe 32. The regulating valve 321 near each discharge port can independently adjust the discharge volume according to specific needs to meet the unloading requirements of different pipelines. Meanwhile, multiple leakage monitoring sensors 33 and vibration sensors 35 installed on the device continuously monitor the equipment's operating status. Once an abnormality is detected, the audible and visual alarm 34 is immediately activated to remind the staff to take appropriate measures.

[0054] Furthermore, the grounding strip 11 remains in constant contact with the ground, effectively preventing static electricity buildup and ensuring safe equipment operation. The camera 36 monitors the feeding process and status in real time, providing support for subsequent operation records and problem tracing. Additionally, the safety light curtains 5 on both sides of the guardrail 4 form a protective barrier during unloading, preventing accidental contact with equipment components or proximity to the unloading area, further enhancing operational safety. Through the coordinated operation of its components, the entire device achieves efficient, precise, and safe unloading operations.

[0055] The above provides a detailed description of the water-based raw material unloading device for tobacco products provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
