DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The singular forms "a", "said" and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0018] It should be understood that although the terms first, second, third, etc. may be used to describe the acquisition modules in the embodiments of the present invention, the acquisition modules should not be limited to these terms. These terms are only used to distinguish the acquisition modules from each other.

[0019] The word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)", depending on the context.

[0020] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present invention are described at the angles shown in the drawings and should not be understood as limiting the embodiments of the present invention. In addition, in the context, it should also be understood that when it is mentioned that an element is formed "on" or "under" another element, it can not only be formed directly "on" or "under" another element, but also be formed "on" or "under" another element indirectly through an intermediate element.

[0021] After entering the cigarette factory, tobacco leaves need to be unpacked and loosened first to facilitate the subsequent silk-making process. Loosening is to change the tobacco leaves from a packaged state to a loose state, so as to facilitate subsequent processes such as beating, stem removal, moisture recovery, and shredding. Therefore, loosening is a necessary pretreatment step in the ingredient silk-making process.

[0022] However, most tobacco companies still use manual unpacking, unbundling and transportation methods. Specifically, warehouse staff stack the cigarette bales on pallets for forklift transportation, and multiple forklifts transfer the stacked cigarette bales to the buffer in front of each unbundling station. The staff at the unbundling station lifts the cigarette bales in the stack to the unbundling table in a timely manner for unpacking and unbundling according to the tobacco leaf sorting speed at the back end, and then transports the unbundled tobacco leaves through forklifts and other equipment.

[0023] This transfer process has the following disadvantages in large-scale, automated tobacco production: a. Low efficiency: Manual and forklift transfer is time-consuming and labor-intensive, with high costs, and it is difficult to meet the needs of large-scale production. b. Occupancy and cumbersome steps: In order to improve production efficiency, multiple scattered workstations are usually used to operate simultaneously, but this not only occupies a large amount of space, but also makes the entire process cumbersome, which is not conducive to further improving production efficiency.

[0024] In view of this, the present embodiment provides a tobacco scattering platform device, which combines the tobacco scattering platform and the transportation after scattering. The scattering platform is not only used as a scattering workbench, but can also provide the scattered tobacco leaves to the conveying device, and then use the conveying device to transport the scattered tobacco leaves outward, so as to solve the above-mentioned technical problems.

[0025] The following is combined with Figure 1-8 The tobacco scattering platform device 100 of this embodiment is introduced.

[0026] Combined with Figure 1 As shown, an embodiment of the present application provides a tobacco leaf scattering platform device 100, including a first frame 10, a conveying device 20, a rotating drive device 30 and a tobacco leaf scattering platform 40.

[0027] The first frame 10 of the present embodiment is the installation base of the entire device, and the functional structures such as the conveying device 20, the rotation driving device 30 and the loose handle platform 40 are directly or indirectly installed on the first frame 10.

[0028] Combined with Figure 2 As shown, in some embodiments, the first frame 10 may include multiple (for example, two in the figure) first support frames 11, each of which may be in a gate shape or other similar shapes, and multiple first support frames 11 may be arranged at intervals and enclose an overall contour that is approximately rectangular or other shapes. Of course, the first frame 10 may also be an integral frame structure (this embodiment is not shown in the figure).

[0029] The first support frame 11 can be formed by welding metal parts such as channel steel, and this embodiment does not impose too many restrictions on this, as long as it can meet the installation requirements of the above-mentioned functional structure.

[0030] In this embodiment, the conveying device 20 is installed on the first frame 10 and is used to convey tobacco leaves. The conveying device 20 is installed on the first frame 10 by mechanical connection methods such as welding and bolt connection, as long as it can meet the requirements of fixed installation.

[0031] Combined with Figure 3 As shown, the conveying device 20 can be a belt conveying structure, or other structures capable of conveying tobacco leaves in one direction, which will not be listed in detail in this embodiment.

[0032] The rotary drive device 30 of this embodiment is installed on the first frame 10 and is at least partially located above the conveying device 20. The rotary drive device 30 is mainly used to drive the loose handle platform 40 to rotate. The optional structure of the rotary drive device 30 is given below.

[0033] The loose handle platform 40 of this embodiment is connected to the rotating drive device 30 and is located above the conveying device 20. The loose handle platform 40 is configured to rotate between a horizontal state and a vertical state under the drive of the rotating drive device 30. The horizontal state refers to that the table top of the loose handle platform 40 is arranged in a horizontal direction, and the vertical state refers to that the table top is arranged in a vertical direction.

[0034] It should be noted that the scattering platform 40 is located above the conveying device 20 in both horizontal and vertical states. The scattering platform 40 in the horizontal state provides a working platform for scattering tobacco leaves, and the scattering platform 40 in the vertical state can drop tobacco leaves to the conveying device 20 for transportation.

[0035] In combination with the above structural description, in this embodiment, a conveying device and a rotating drive device 30 are installed on the first frame 10, and a scattering platform 40 is installed on the rotating drive device 30. When the scattering platform 40 is driven by the rotating drive device 30 to rotate to a horizontal state, the scattering platform 40 can provide a working platform for the scattering processing of tobacco leaves. When the scattering platform 40 is rotated to a vertical state, the scattered tobacco leaves can fall into the conveying device 20 so as to be transported to the next process.

[0036] Compared with the related technologies that rely on manual transportation and occupy too much site space for scattering tobacco, the tobacco scattering platform equipment 100 provided by the present invention integrates the tobacco scattering platform 40 and the conveying device 20, which reduces the site occupancy and can realize automatic unloading and conveying after scattering, thereby improving production efficiency and reducing manpower and equipment costs.

[0037] Combined with Figure 1 , Attachment Figure 4-6 As shown, in some examples, optionally, the rotation drive device 30 of this embodiment includes a second frame 31 , a drive assembly 32 and a rotation assembly 33 .

[0038] The second frame 31 of this embodiment is installed on the first frame 10, and is at least partially located above the conveying device 20. Figure 4 As shown, the number of the second racks 31 of this embodiment can be two, and each second rack 31 can include one or more (for example, two in the figure) second support racks 311, and the second support racks 311 can be in a mouth shape or a door shape.

[0039] The second support frame 311 can also be a support structure formed by processing metal parts such as channel steel. The function of the second frame 31 is to install the driving component 32 and the rotating component 33, and to make the driving component 32 and the rotating component 33 have a certain installation height to facilitate the installation of the loose handle platform 40.

[0040] The driving assembly 32 of this embodiment is installed on the second frame 31, and the installation method can be any mechanical connection method, specifically welding, bolt connection, etc., which are not listed one by one in this embodiment.

[0041] The rotating assembly 33 can be directly or indirectly mounted on the second frame 31, the rotating assembly 33 is connected to the transmission assembly, and the rotating assembly 33 is connected to the loose handle platform 40. The driving assembly 32 provides driving force for the rotating assembly 33, drives the rotating assembly 33 to move, and thus drives the loose handle platform 40 to rotate.

[0042] The drive assembly 32 and the rotating assembly 33 of this embodiment may have various structural forms. For example, the drive assembly 32 may include a drive motor, and the rotating assembly 33 may include a rotating shaft 331 , and the two are directly connected (this embodiment is not shown in the figure).

[0043] In order to improve the rotational stability and the service life of each component, the present embodiment provides a matched driving component 32 and a rotating component 33, which utilize the conversion of linear motion into rotation.

[0044] Combined with Figure 5 As shown, in some examples, optionally, the driving assembly 32 of this embodiment includes a first mounting member 321 and a first linear reciprocating motion mechanism 322, and the first mounting member 321 is fixedly connected to the second frame 31 of this embodiment by welding or the like.

[0045] In some embodiments, the first mounting member 321 can also be regarded as a part of the second frame 31. The first mounting member 321 is mainly used to install the driving component 32 and the rotating component 33. The first mounting member 321 can be a plate-shaped member or a block-shaped member, etc., and its material can be metal or non-metal with a certain structural strength.

[0046] Combined with Figure 6 As shown, the rotating assembly 33 of this embodiment includes a transmission mechanism 332, a shaft seat 333 and a rotating shaft 331, wherein the transmission mechanism 332 and the shaft seat 333 are both installed on the first mounting member 321, and the number of the shaft seats 333 can be two, so as to be used to install the two ends of the rotating shaft 331 to improve the stability of the rotating shaft 331 during rotation. Accordingly, two support seats 323 can be configured on the first mounting member 321 for installing two shaft seats 333.

[0047] The rotating shaft 331 of this embodiment is connected to the shaft seat 333 in a manner that it can rotate around its own axis. The first linear reciprocating member, the transmission mechanism 332 and the rotating shaft 331 are sequentially connected in transmission, and the loose handle platform 40 is installed on the rotating shaft 331.

[0048] The movement of the first linear reciprocating member drives the transmission mechanism 332 to move, thereby driving the rotating shaft 331 to rotate.

[0049] In some examples, optionally, the transmission mechanism 332 includes a first track member 3321 , a first sliding member 3322 , a first rack 3323 , and a first gear 3324 .

[0050] Among them, the first track member 3321 can be a plate-shaped member or a block-shaped member, and a first slide rail 33211 is arranged on the first track member 3321. The number of the first slide rails 33211 can be one or more as shown in the figure. A first slider 33221 is provided at the bottom of the first sliding member 3322, and the first slider 33221 is slidably connected to the first slide rail 33211 so that the first sliding member 3322 can slide in a horizontal direction perpendicular to the axial direction of the rotation axis 331.

[0051] The first rack 3323 is connected to the upper surface of the first sliding member 3322. The connection method can be a fixed connection such as welding, or the first rack 3323 and the first sliding member 3322 can be integrally formed. The number of the first rack 3323 can be one or more.

[0052] The first gear 3324 meshes with the first rack 3323, and the first gear 3324 is coaxially connected to the rotating shaft 331. In some embodiments, the first gear 3324 is a helical gear with helical teeth, and the first rack 3323 is a helical rack with helical teeth. The cooperation of the helical gear and the helical rack has the advantages of stable transmission, strong load-bearing, compact structure, low noise, and long life.

[0053] The first linear reciprocating motion mechanism 322 is connected to the first sliding member 3322, and drives the first sliding member 3322 to slide in the horizontal direction on the first track member 3321, so that the rack on the first sliding member 3322 can drive the first gear 3324 to rotate, and the rotation of the first gear 3324 synchronously drives the rotating shaft 331 installed on the shaft seat 333 to rotate, thereby driving the loose handle platform 40 to rotate.

[0054] Of course, the structural form of the transmission mechanism 332 of this embodiment is not limited to this. Other transmission mechanisms 332 that can convert the linear motion of the first linear reciprocating motion mechanism 322 into rotational motion are also within the optional range of this embodiment, such as crank sliders, cams and other structures, which are not listed one by one in this embodiment.

[0055] Combined with Figure 7As shown, in order to match the above-mentioned transmission mechanism 332, the rotating shaft 331 of this embodiment includes multiple shaft sections with different shaft diameters, for example, including the first shaft section 3311, the second shaft section 3312, the third shaft section 3313, the fourth shaft section 3314 and the fifth shaft section 3315 in the figure, wherein the first shaft section 3311, the third shaft section 3313 and the fourth shaft section 3314 are provided with threads, and the first shaft section 3311, the third shaft section 3313 and the fifth shaft section 3315 are provided with keyways, the first shaft section 3311 is used to connect the shaft seat 333, the second shaft section 3312 is used for the transition between the first shaft section 3311 and the third shaft section 3313, the third shaft section 3313 is used to dock the coupling assembly 43 of this embodiment, the fourth shaft section 3314 is used for the transition between the third shaft section 3313 and the fifth shaft section 3315, and the fifth shaft section 3315 is used to connect the first gear 3324.

[0056] In some examples, optionally, the first linear reciprocating motion mechanism 322 includes a first cylinder 3221 and a first connecting block 3222 , the piston rod of the first cylinder 3221 is connected to the first connecting block 3222 , and the first connecting block 3222 is connected to the first sliding member 3322 .

[0057] Of course, the first cylinder 3221 can also be replaced by a hydraulic cylinder or an electric cylinder, as long as it can drive the first connecting block 3222 to reciprocate along an axial straight line perpendicular to the rotating shaft 331 .

[0058] In order to improve the installation stability of the first cylinder 3221, the drive assembly 32 can be designed to also include a cylinder support 324. The cylinder support 324 may include a rectangular support plate and triangular support plates connected to the rectangular support plate at opposite ends of the axial direction of the rotating shaft 331. The rectangular support plate and the triangular support plate are both fixedly mounted on the above-mentioned first mounting member 321, and the cylinder is fixedly mounted on the rectangular support plate.

[0059] Combined with Figure 8 As shown, in some examples, optionally, the loose handlebar platform 40 includes a support frame 41 , a platform plate 42 and at least one coupling assembly 43 .

[0060] Among them, the main shape of the support frame 41 of this embodiment can be a rectangle, and of course it can also be other similar shapes. A plurality of support frames are arranged inside the support frame 41, and adjacent support frames are spaced apart and enclose openings that pass through two opposite surfaces of the support frame 41. This support frame 41 structure not only has good supporting performance, but also can reduce weight through the openings.

[0061] The support frame 41 may be made of metal materials such as steel and aluminum alloy, or may be made of a polymer material with a certain structural strength, which is not limited in this embodiment.

[0062] The platform plate 42 is installed on one of the opposite sides of the support frame 41 . Specifically, the platform plate 42 is installed on the side of the support frame 41 facing away from the rotation drive device 30 .

[0063] The platform plate 42 is a whole plate-like structure. The platform plate 42 and the support frame 41 can be fixed by mechanical connection methods such as welding, bolt connection, screw connection, etc. The material of the platform plate 42 can be the same as or similar to that of the support frame 41. For example, the platform plate 42 can be a metal material such as aluminum alloy.

[0064] The platform plate 42 is mainly used as a platform for spreading tobacco leaves, so the surface of the platform plate 42 away from the support frame 41 needs to have a certain degree of flatness and smoothness.

[0065] The coupling assembly 43 of this embodiment is installed on the other side of the opposite sides of the support frame 41 and is connected to the rotating shaft 331. The main function of the coupling assembly 43 is to connect the rotating shaft 331, so that the rotating shaft 331 drives the support frame 41 and the platform plate 42 of this embodiment to rotate synchronously.

[0066] In some examples, optionally, the coupling assembly 43 of this embodiment includes two support members 431 and one connecting member 432 .

[0067] The two support members 431 are arranged at intervals along the axial direction of the rotating shaft 331. The support member 431 may be a trapezoidal plate-shaped member as shown in the figure. The long side of the trapezoidal support member 431 is fixedly connected to the support frame 41 of this embodiment. The fixed connection method is not limited, for example, it can be said to be welding or bolt connection. The trapezoidal support member 431 has better structural stability, so that the rotating shaft 331 and the support frame 41 of this embodiment can be connected more stably.

[0068] The connecting member 432 is located between the two supporting members 431 , and is fixedly connected to the two supporting members 431 at opposite ends of the axial direction of the rotating shaft 331 , and both the connecting member 432 and the supporting member 431 are provided with an axial hole for the rotating shaft 331 to pass through.

[0069] The rotating shaft 331 is installed on the two supporting members 431 and the connecting member 432 through the above-mentioned shaft hole, and is fixedly connected with the connecting member 432 through a keyway and other structures, so that the rotation of the rotating shaft 331 can drive the coupling assembly 43 and the platform plate 42 to rotate.

[0070] Of course, the structural form of the coupling assembly 43 of this embodiment is not limited to the above structure, and can also be a coupling structure in other related technologies, as long as it can dock with the rotating shaft 331 and rotate synchronously with the rotating shaft 331. This embodiment will not be described in detail.

[0071] Combined with the attachment again Figure 1 As shown, in some examples, optionally, in this embodiment, the number of the rotation drive devices 30 and the number of the loose handle platforms 40 are both two, and the two rotation drive devices 30 and the two loose handle platforms 40 are connected in a one-to-one correspondence.

[0072] Specifically, the number of the second frame 31, the driving assembly 32 and the rotating assembly 33 are two, and the rotating shafts 331 of the two rotating assemblies 33 are connected to the two loose handle platforms 40 one by one, thereby driving the two loose handle platforms 40 to rotate. The two loose handle platforms 40 can provide a larger working surface after being combined.

[0073] In this embodiment, one of the two rotation driving devices 30 is located at one end of the first frame 10 along the conveying direction of the conveying device 20 , and the other is located at the other end of the first frame 10 along the conveying direction of the conveying device 20 .

[0074] The two loose handle platforms 40 are connected to the two rotating components 33 in a one-to-one correspondence, and in this embodiment, the spatial positions of the two loose handle platforms 40 are designed so that the two loose handle platforms 40 are overlapped in a horizontal state to form an integral working platform.

[0075] In addition, in this embodiment, the lower ends of the scattered tobacco platforms 40 in the vertical state are spaced apart from the conveying device 20 , thereby facilitating the rotation of the scattered tobacco platforms 40 and allowing the scattered tobacco leaves to fall directly onto the conveying device 20 .

[0076] Combined with the attachment again Figure 1 and attached Figure 4 As shown, in order to enable the tobacco scattering platform 40 to scatter the tobacco leaves better and reduce the possibility of the tobacco leaves escaping from the scattering platform 40, in some examples, optionally, the tobacco scattering platform device 100 of this embodiment also includes a back plate 50.

[0077] The back panel 50 is vertically mounted on the first frame 10 and is adjacent to the two loose handle platforms 40. The two loose handle platforms 40 overlap with the back panel 50 in a horizontal state, so that the two loose handle platforms 40 and the back panel 50 are perpendicular to each other, forming a form similar to a seat and a backrest. For example, the two loose handle platforms 40 can be regarded as a seat, and the back panel 50 can be regarded as a backrest.

[0078] The back plate 50 can be installed on the first rack 10 or the second rack 31 of this embodiment through a second mounting member 51 such as an angle steel or a channel steel. This embodiment does not impose too many restrictions on this, as long as the installation height and stability requirements of the back plate 50 can be met.

[0079] In addition, in some examples, optionally, the tobacco leaf scattering platform equipment 100 of the present embodiment further includes a scattering device (not shown in the figure), which is used to scatter the tobacco leaves on the scattering platform 40.

[0080] The loose handle device can be installed on the first frame 10, the second frame 31 or the back plate 50 mentioned above, or the loose handle device can be installed on other frames not shown in the drawings.

[0081] Regarding the specific structural form of the scattering device, it can be any device in the relevant technology that can perform mechanical and automated scattering. For example, the scattering device can include a mechanical target nail type scattering mechanism, which realizes the scattering of tobacco leaves by driving the target nail to rotate through a roller. For another example, the scattering device can include a pneumatic scattering structure with an air nozzle to blow the tobacco leaves.
