Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco production technology, and in particular to a transportation anti-blockage device. Background Technology
[0002] In the tobacco processing, tobacco leaves need to be transported via multiple conveyor belts and screening troughs. After being dispersed by large rollers at the end of the leaf storage cabinet, they enter the screening trough and are then conveyed by a conveyor belt to the screening trough for sieving. Qualified leaves are used for shredding. A protective cover is installed at the connection between the conveyor belt and the screening trough to prevent dust from falling onto the material. However, because the rollers at the end of the leaf storage cabinet can only roughly disperse the leaves, many leaf clumps remain on the conveyor belt, clogging the connection and causing equipment downtime, thus reducing production efficiency and affecting the continuity of operations.
[0003] Therefore, there is an urgent need for a transportation anti-blockage device to solve the above-mentioned technical problems. Utility Model Content
[0004] The purpose of this invention is to provide a transport anti-blockage device that can further break up material clumps to prevent blockages during transport, thereby avoiding the risk of equipment downtime, improving production efficiency, and ensuring the continuity of operations.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] A transport anti-blockage device, comprising:
[0007] A conveying mechanism for conveying materials along a first direction;
[0008] A spiral mechanism is provided at the unloading end of the conveying mechanism. The spiral mechanism includes a driving component and a spiral assembly. The spiral assembly includes a rotating shaft and multiple impactors. The rotating shaft is arranged vertically. The driving component is used to drive the rotating shaft to rotate around the vertical direction. The impactors are generally arc-shaped. Multiple impactors are arranged on the outer periphery of the rotating shaft. When the rotating shaft rotates around the vertical direction, the outer curved parts of the multiple impactors can knock the accumulated material in turn to prevent the accumulated material from blocking the unloading end of the conveying mechanism.
[0009] Preferably, the conveying mechanism has spiral assemblies on both sides of the unloading end along the width direction.
[0010] Preferably, the two spiral assemblies rotate in opposite directions, and both are struck by the outer curved portion of the impactor.
[0011] Preferably, at the same height of each of the rotating shafts, a plurality of impact members are arranged circumferentially to form an impact kit, and the rotating shafts are spaced apart in the vertical direction by a plurality of the impact kits.
[0012] Preferably, all of the impact kits are arranged facing each other.
[0013] Preferably, the helical mechanism further includes a timing belt that is simultaneously connected to both of the rotating shafts, so that the driving member can simultaneously drive both rotating shafts to rotate in the vertical direction.
[0014] Preferably, the transport anti-blocking device further includes a protective cover, and both of the spiral assemblies are located inside the protective cover.
[0015] Preferably, all of the impact components are made of a rigid material.
[0016] Preferably, a sensor is provided in the middle of the conveying mechanism. The sensor is used to detect the height of the material. The sensor is communicatively connected to the drive unit. When the detected height exceeds a preset height, the drive unit is activated.
[0017] Preferably, the sensing element is provided on both sides of the conveying mechanism along the width direction.
[0018] The beneficial effects of this utility model are:
[0019] This utility model discloses a transport anti-blockage device. The device includes a conveying mechanism and a screw mechanism; the conveying mechanism is used to convey materials along a first direction; the screw mechanism is located at the discharge end of the conveying mechanism and includes a driving component and a screw assembly. The screw assembly includes a rotating shaft and multiple impact members. The rotating shaft is arranged vertically, and the driving component drives the rotating shaft to rotate around the vertical direction. The impact members are generally arc-shaped, and multiple impact members are arranged on the outer periphery of the rotating shaft. When the rotating shaft rotates around the vertical direction, the outer curved portions of the multiple impact members can take turns striking the accumulated material to prevent the accumulated material from blocking the discharge end of the conveying mechanism. This device can further break up material clumps to prevent blockages during transport, thereby avoiding the risk of equipment downtime, improving production efficiency, and ensuring continuous operation.
[0020] In this device, the conveying mechanism automatically transports materials (tobacco shreds). When the material passes the discharge end, the drive unit drives the rotating shaft to rotate vertically, causing multiple impactors to rotate. During rotation, the impactors take turns impacting the accumulated material, breaking it down into smaller pieces. This prevents large volumes of material from clogging the discharge end of the conveying mechanism, ensuring a good anti-clogging effect. Furthermore, the impactors are arc-shaped, allowing them to smoothly glide over the surface after impacting the accumulated material, avoiding jamming. Attached Figure Description

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning.
[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0033] like Figures 1 to 3 As shown, this utility model provides a conveying mechanism 10 and a screw mechanism 20. The conveying mechanism 10 is used to convey materials along a first direction. The screw mechanism 20 is disposed at the discharge end of the conveying mechanism 10. The screw mechanism 20 includes a driving member and a screw assembly. The screw assembly includes a rotating shaft 21 and multiple impact members 22. The rotating shaft 21 is disposed in a vertical direction. The driving member is used to drive the rotating shaft 21 to rotate around the vertical direction. The impact members 22 are generally arc-shaped. Multiple impact members 22 are disposed on the outer periphery of the rotating shaft 21. When the rotating shaft 21 rotates around the vertical direction, the outer curved parts of the multiple impact members 22 can knock the accumulated material in turn to prevent the accumulated material from blocking the discharge end of the conveying mechanism 10.
[0034] In this device, the conveying mechanism 10 can automatically convey materials (tobacco shreds). When the material passes the discharge end, the drive unit can drive the rotating shaft 21 to rotate in the vertical direction, thereby causing the rotating shaft 21 to drive multiple impact members 22 to rotate. During the rotation, the impact members 22 can impact the accumulated material in turn, thereby breaking the accumulated material into smaller pieces, thus preventing large-volume accumulated material from clogging the discharge end of the conveying mechanism 10, thus ensuring a good anti-clogging effect. In addition, the impact members 22 are arc-shaped, so they can smoothly slide over the surface after impacting the accumulated material, avoiding being jammed by the accumulated material.
[0035] like Figure 1 As shown, the feeding end of the conveying mechanism 10 is equipped with spiral components on both sides along the width direction. This arrangement allows for simultaneous tapping from both sides of the accumulated material, thereby improving tapping efficiency, ensuring a good tapping effect, and preventing material from remaining on one side, thus ensuring that the feeding end is not blocked.
[0036] like Figure 1 and Figure 3As shown, the two spiral assemblies rotate in opposite directions (the shaft 21 on the left side of the conveyor mechanism 10 rotates counterclockwise, and the shaft 21 on the right side of the conveyor mechanism 10 rotates clockwise), and both are struck by the outer curved portion of the impact member 22 to break up the accumulated material. This arrangement allows the accumulated material to be struck in opposite directions, which not only improves the dispersing effect but also prevents the material from falling off the conveyor mechanism 10 due to force applied in one direction, thus avoiding material waste or difficulty in cleaning.
[0037] like Figures 2-3 As shown, at the same height on each rotating shaft 21, multiple impact members 22 are arranged circumferentially to form an impact kit, and multiple impact kits are spaced apart vertically on the rotating shaft 21. In this structure, multiple impact members 22 at the same height can impact the accumulated material in turn, thereby ensuring that a certain height can receive a sufficiently large impact force, thus ensuring the dispersing effect; and multiple impact kits are arranged vertically on the rotating shaft 21, and multiple impact kits can simultaneously impact the accumulated material at different positions, thereby enabling the accumulated material to be dispersed from multiple heights, which greatly improves the hammering effect.
[0038] like Figure 2 and Figure 3 As shown, multiple impact kits are arranged facing each other. This structure not only ensures the uniformity of force on the accumulated material during impact but also improves the external aesthetics of the screw mechanism 20. It should be noted that in this embodiment, each impact kit includes three impact members 22, with an included angle of 120° between the impact members 22. In other embodiments, the number of impact members 22 in each impact kit can be adjusted according to actual needs, as can the total number of impact kits. This embodiment does not limit the specific number.
[0039] like Figure 1 As shown, the screw mechanism 20 also includes a synchronous belt, which is simultaneously connected to both rotating shafts 21 for transmission, so that the driving component can simultaneously drive both rotating shafts 21 to rotate in the vertical direction. This arrangement ensures that the two rotating shafts 21 rotate synchronously, improving the synchronicity of the impact on the accumulated material; in addition, it can reduce the number of driving components, requiring only one driving component to rotate both rotating shafts 21, thus reducing costs and saving installation space. It should be noted that in this embodiment, the driving component is a rotary motor.
[0040] like Figure 1 As shown, the anti-blocking device for transport also includes a protective cover 30, with both spiral assemblies located inside the protective cover 30. This arrangement can cover the part where the feeding end connects with other structures, thereby preventing tobacco from falling during connection; in addition, the protective cover 30 can also enclose the two spiral assemblies inside, thereby ensuring the safety of operation and preventing the spiral assemblies from hitting the workers when rotating.
[0041] It should be noted that in this embodiment, all the impactors 22 are made of rigid materials. Rigid materials can prevent deformation during the impact process, thereby generating sufficient impact force to ensure a good dispersing effect and prevent material from clogging the discharge end.
[0042] It should be noted that, in this embodiment, a sensor is provided in the middle of the conveying mechanism 10. The sensor is used to detect the height of the material. The sensor is communicatively connected to the drive unit. When the detected height exceeds the preset height, the drive unit is activated. Since the height of the accumulated material is usually quite high, when the sensor detects that the actual height of the material exceeds the preset value, it automatically transmits the information to the drive unit. At this time, the drive unit immediately drives the spiral assembly to rotate, thereby breaking up the accumulated material and preventing blockage at the discharge end.
[0043] Furthermore, in this embodiment, sensors are provided on both sides of the conveying mechanism 10 along its width. This arrangement allows for simultaneous detection from both sides of the conveying mechanism 10, and regardless of which side the material height exceeds a preset height, the drive unit can be activated to drive the two spiral assemblies to rotate.
[0044] Referring to the accompanying drawings, the working process of the transport anti-blockage device in this embodiment is described below:
[0045] First, the conveying mechanism 10 conveys materials along a first direction;
[0046] Secondly, when the material reaches the middle of the conveying mechanism 10, the sensor detects the actual height of the material;
[0047] Finally, when the detection height exceeds the preset height, the drive unit is activated, and the two spiral components rotate in opposite directions simultaneously, thereby breaking up the accumulated material and preventing blockage at the discharge end.
[0048] In summary, the anti-blockage device in this embodiment can further break up the clumps of materials to prevent blockages during transportation, thereby avoiding the risk of equipment downtime, improving production efficiency, and ensuring the continuity of operations.
[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
