Description

Technical Field

[0001] This disclosure relates to the field of tobacco equipment maintenance technology, and in particular to a tobacco conveyor belt maintenance tool and a tobacco production system. Background Technology

[0002] Currently, the disassembly and replacement of high-speed belts on tobacco conveyor belts are typically performed using traditional methods. This involves inserting a fixed cylindrical tube into the hole between the frame's circular hole and the liner plate. First, the support block above the mounting surface of the frame is removed, followed by the bolts connecting the lower support block to the frame. With the cooperation of three mechanics, a downward force is applied to the cylindrical tube, causing the frame to tilt, allowing for the removal of the lower support block. This belt disassembly and replacement process is often very time-consuming and requires a large amount of manpower, while also posing uncontrollable safety risks. Utility Model Content

It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0033] Based on the embodiments disclosed above, in the absence of explicit denial or conflict, the technical features of one embodiment may be advantageously combined with one or more other embodiments.

[0034] During their research, the inventors discovered that the high-speed belt of the leaf-splitter air separator used in tobacco production has five structural characteristics: 1. Large lateral span; 2. Large weight; 3. Compact structure of the main roller end mounting surface; 4. The belt adopts a ring structure; 5. Due to functional requirements, the belt conveyor has a slope. These characteristics lead to three main difficulties when replacing the belt: First, after removing the mounting surface liner and frame fixing support block, due to structural characteristics 1, 2, and 3, the frame is prone to sinking, and the mounting gap at the main roller end is insufficient for the ring belt to pass smoothly; Second, due to structural characteristic 4, it is impossible for people to stand inside the area where the ring belt is located, which greatly increases the difficulty of lifting the frame to install a new belt.

[0035] To solve at least one of the above-mentioned technical problems, this disclosure proposes a maintenance fixture for tobacco conveyor belts, such as... Figures 1 to 4 As shown, the liner frame 100 is used to lift the tobacco conveyor belt. The tobacco conveyor belt maintenance fixtures include:

[0036] The lifting arm 1 includes a main body 11 and a gripping assembly 12. The main body 11 extends along a first direction x, and the gripping assembly 12 is connected to a first end of the main body 11. The gripping assembly 12 is configured to support the liner frame 100.

[0037] Support rod 2 is connected to the second end of the main body 11 away from the liner frame 100. Support rod 2 extends along the height direction z, and the height direction z intersects with the first direction x; and

[0038] The lifting drive component 3 is located at the first end of the support rod 2 away from the lifting arm 1, and the lifting drive component 3 is configured to lift the support rod 2 along the height direction z.

[0039] Specifically, during the movement of the liner frame 100 along the height direction z, the liner frame 100 is pressed against the gripping assembly 12 by gravity. Through the cooperation between the liner frame 100 and the gripping assembly 12, the lifting arm 1 supports the liner frame 100. Specifically, the liner frame 100 includes a protrusion 101 that cooperates with the gripping assembly 12. The protrusion 101 fits into the gripping assembly 12. The protrusion 101 is an inherent structure of the liner frame 100 and does not require additional installation on the liner frame 100. For example, the protrusion 101 can be a sheet metal folded edge of the liner frame 100.

[0040] Specifically, by setting up the lifting arm 1 and the support rod 2, the lifting force application position can be moved outward from the belt, which can not only avoid the problem that people cannot stand inside the area where the ring belt is located, thus improving the safety of the maintenance process, but also facilitate the installation of the belt along the extension direction of the lifting arm 1 to the liner frame 100; through the lifting drive component 3, the liner frame 100 can be easily lifted to a suitable position, thereby achieving effective support and fixation of the belt conveyor and reducing the manpower required.

[0041] Optionally, maintenance of the tobacco conveyor belt may include replacing the belt or replacing the support blocks of the liner frame 100, such as disassembling and assembling the upper support block 102 or the lower support block 103. Optionally, the tobacco conveyor belt maintenance fixture disclosed herein is applicable to various tobacco conveyor belts, such as for high-speed belt maintenance of leaf trimmer air separator units.

[0042] Optionally, to prevent relative displacement or sliding between the lifting arm 1 and the support rod 2 during the lifting process, the lifting arm 1 can be made into a polygon to increase friction, such as a rectangle or a regular hexagon. Alternatively, the lifting arm 1 and the support rod 2 can be fixedly connected. Optionally, the lifting drive component 3 can be an electric lift or a jack.

[0043] The maintenance fixture for the tobacco conveyor belt in this embodiment has a simple and reliable structure, which can safely and effectively lift the belt liner frame 100, simplify the belt installation process, and enable quick and convenient belt installation. It requires fewer operators, reduces the labor and time costs of replacing high-speed belts in the tobacco conveyor belt, and improves the safety of the tobacco conveyor belt maintenance process.

[0044] In some embodiments, the support rod 2 is movable along a first direction x near the second end of the lifting arm 1.

[0045] In this embodiment, the support rod 2 is movable along the first direction x near the second end of the lifting arm 1, which can flexibly change the torque according to the actual needs during maintenance; it can also avoid the support rod 2 blocking the drag of the belt, that is, the belt can be installed on the lifting arm first, and then the support rod 2 can be installed to the second end of the lifting arm 1.

[0046] In some embodiments, such as Figure 2 As shown, the lifting arm 1 is rectangular, and the support rod 2 has a rectangular frame near the second end of the lifting arm 1. The second end of the main body 11 is located inside the rectangular frame.

[0047] In this embodiment, the rectangular lifting arm 1 and the support rod 2 are fitted together with a rectangular frame, which can increase the static friction between the lifting arm 1 and the support rod 2 during the lifting process, effectively avoid displacement or slippage during the lifting process, and improve the safety of the maintenance tooling for the tobacco conveyor belt.

[0048] In some embodiments, the length of the lifting arm 1 along the first direction x is greater than the width of the tobacco conveyor belt.

[0049] In this embodiment, the length of the lifting arm 1 along the first direction x is greater than the width of the tobacco belt conveyor, which allows the belt to be laid flat before being installed on the liner frame 100, and then the belt can be directly dragged for replacement, thereby improving the belt replacement efficiency.

[0050] In some embodiments, such as Figure 1 As shown, the liner frame 100 includes a protrusion 101, and the gripping assembly 12 includes:

[0051] The connecting part 121 is connected to the first end face of the main body part 11;

[0052] The limiting part 122 and the connecting part 121 are arranged at intervals relative to each other along the first direction x, and the limiting part 122 and the connecting part 121 cooperate to restrict the movement of the main body 11 along the first direction x; and

[0053] The lifting part 123 is connected between the connecting part 121 and the limiting part 122, and the lifting part 123 is configured to support the bottom surface of the protrusion 101.

[0054] Specifically, during the movement of the liner frame 100 along the height direction z, the protrusion 101 is located between the connecting portion 121 and the limiting portion 122 along the first direction x. The protrusion 101 cooperates with the limiting portion 122 to restrict the main body 11 from moving away from the liner frame 100, and also cooperates with the connecting portion 121 to restrict the main body 11 from moving closer to the liner frame 100. Specifically, the inner surfaces of the connecting portion 121, the limiting portion 122, and the lifting portion 123 of the gripping assembly 12 all fit with the protrusion 101.

[0055] The gripping assembly 12 of this embodiment, by providing a connecting part 121, a limiting part 122, and a lifting part 123, can adapt to the complexity and size requirements of the liner frame structure, and can ensure a firm fit between the gripping assembly 12 and the frame, thereby enhancing the stability and safety of the maintenance tooling.

[0056] In some embodiments, the inner surfaces of the connecting portion 121, the limiting portion 122, and the supporting portion 123 are attached to the outer surface of the protrusion 101.

[0057] Specifically, the sum of the gaps between the inner surfaces of the connecting part 121, the limiting part 122, and the supporting part 123 and the outer surface of the protrusion 101 is less than a preset distance.

[0058] In this embodiment, the inner side of the gripping assembly 12 is attached to the outer side of the protrusion 101, which can further improve the stability of the tobacco conveyor belt maintenance tool during use.

[0059] During the research process, the inventors also discovered that due to structural feature 5, the mounting surface and the liner frame are not horizontal after the belt is installed. When using the traditional installation method to tilt the frame to install the fixed support block, there is a certain safety hazard.

[0060] To address the above problems, in some embodiments, such as Figure 4 As shown, the acute angle between the belt extension direction of the tobacco conveyor and the horizontal plane is the first angle, and the acute angle between the inner side of the lifting part 123 and the horizontal plane is the second angle, which is equal to the first angle.

[0061] Optionally, the first included angle and the second included angle can be 30° or 45°, etc.

[0062] This embodiment, by setting the second included angle to be equal to the first included angle, enables the lifting part 123 to conform to the slope of the belt conveyor, and enables the liner frame 100 to move strictly along the height direction z, thereby eliminating safety hazards from the root and improving the safety of tobacco belt conveyor maintenance.

[0063] In some embodiments, the lifting drive component 3 includes a horizontal jack.

[0064] This embodiment uses the lifting action of a horizontal jack to lift the liner frame 100 to a suitable position, thereby achieving effective support and fixation for the belt conveyor. Based on this, the belt can be directly dragged for replacement, or liner frame support blocks can be installed, which can greatly improve work efficiency and safety.

[0065] In some embodiments, the gripping assembly 12 is welded to the main body 11.

[0066] In this embodiment, the gripping assembly 12 is welded to the main body 11. The gripping assembly 12 can be firmly welded to the main body 11 through welding technology, which can improve the reliability and stability of the tobacco conveyor belt maintenance tool.

[0067] Secondly, this disclosure also proposes a tobacco production system, including the tobacco conveyor belt maintenance fixture of the above embodiments.

[0068] Specifically, the tobacco production system also includes a leaf threshing machine and a tobacco air classifier 200. The leaf threshing machine is located upstream of the tobacco conveyor belt, and the air classifier is located downstream of the tobacco conveyor belt. Specifically, the connecting part 121 is welded to the main body 11. The installation position of the tobacco conveyor belt or the installation height of the liner frame 100 is greater than a preset height, for example, a preset height of 1.5 meters.

[0069] This embodiment enables convenient and quick belt replacement by setting up belt conveyor maintenance fixtures in the tobacco production system, thereby reducing labor and time costs in the process of replacing high-speed belts on tobacco belt conveyors and improving the production efficiency of the tobacco production system.

[0070] In some embodiments, the tobacco belt conveyor further includes a belt alignment mechanism 104, which is configured to issue an alarm when the belt deviates from a first preset area and to stop the tobacco belt conveyor when the belt deviates from a second preset area.

[0071] In some embodiments, such as Figure 4 As shown, the tobacco air separation equipment 200 includes a regulating air valve, an exhaust hood, a lamp cover, a limit switch, an observation door, a middle chamber, a reducer, a mesh belt, a lower chamber, and a cleaning door. The regulating air valve is used to regulate the air intake of the air separation equipment, the exhaust hood is used to transport tobacco leaves and other tobacco materials into the downstream production process, the mesh belt is used to transport tobacco stems and other tobacco materials for secondary air separation, and the lower chamber is used to store debris and other waste materials.

[0072] The foregoing has provided a detailed description of a tobacco conveyor belt maintenance fixture and tobacco production system provided in this disclosure. Specific embodiments have been used to illustrate the principles and implementation methods of this disclosure. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this disclosure. It should be noted that those skilled in the art can make various improvements and modifications to this disclosure without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this disclosure.
