DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the utility model clearer, the technical scheme of the utility model will be described clearly and completely in combination with specific embodiments below. The same reference signs in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0037] Compared with the embodiments shown in the drawings, the feasible implementation schemes within the protection scope of the utility model can have fewer components, other components not shown in the drawings, different components, differently arranged components or differently connected components, etc. In addition, two or more components in the drawings can be implemented in a single component, or a single component shown in the drawings can be implemented as multiple separate components.

[0038] The embodiments of the utility model disclose a whole lifting loading and unloading system of a curing barn, which is suitable for loading and unloading operation of a tobacco clamp. Wherein, the tobacco clamp is a clamp capable of storing a certain amount of tobacco leaves known in the prior art, through the use of the tobacco clamp, the tobacco leaves can be conveniently hung in the curing barn for curing. Of course, the whole lifting loading and unloading system of the curing barn disclosed in the embodiments of the utility model is not only suitable for loading and unloading operation of the tobacco clamp, but also can be applied to other devices similar to the tobacco clamp suitable for storing tobacco leaves.

[0039] For the convenience of description, the whole lifting loading and unloading system of the curing barn disclosed in the embodiments of the utility model will be referred to as "loading and unloading system" hereinafter.

[0040] Figure 1 The structural schematic diagram of the exemplary loading and unloading system disclosed in the embodiments of the utility model, Figure 2 In order to Figure 1 The reference drawing when the loading and unloading system shown is arranged in the curing barn. In Figure 1 And Figure 2 The embodiments shown, the loading and unloading system can include a movable support frame 10 and a follow-up support frame 20.

[0041] Referring to Figure 2 It is shown that the movable support frame 10 and the follow-up support frame 20 are arranged inside the curing barn for use, and the movable support frame 10 and the follow-up support frame 20 are both suitable for supporting a certain amount of tobacco clamps in the curing barn along the longitudinal direction of the curing barn.

[0042] In order to realize the reasonable use of the limited space inside the curing barn, referring to Figure 3As shown, the structures of the movable support frame 10 and the follow-up support frame 20 can be the same. Specifically, the movable support frame 10 and the follow-up support frame 20 can each include a plurality of support plates 11 arranged in the horizontal direction in sequence inside the curing barn, and the support plates 11 of each support frame extend in the longitudinal direction of the curing barn to define a plurality of curing zones arranged in the horizontal direction in sequence between adjacent two support plates 11. Moreover, for a single support frame, the distance between adjacent two support plates 11 in the single support frame is not greater than the length of the tobacco clip to be stored. For example, the utility model discloses that the drawings show that each support frame includes three support plates 11, at which time, the interior of the curing barn is divided into two curing zones in the horizontal direction.

[0043] When it is necessary to store the tobacco clip inside the curing barn, the curing zones can each place the tobacco clip. For a single curing zone, a plurality of tobacco clips arranged in the longitudinal direction of the curing barn can be placed in sequence between adjacent two support plates 11 of each support frame. Among them, the two ends of the tobacco clip in the length direction are respectively supported on the adjacent two support plates 11.

[0044] Further, the number of movable support frames 10 can also be multiple. In the case of multiple movable support frames 10, the multiple movable support frames 10 are arranged in the height direction in sequence so that the interior of the curing barn can store more tobacco clips. For example, based on the general size of the curing barn, the drawings of the utility model show that a single curing barn is provided with two movable support frames 10 arranged in the height direction in sequence.

[0045] The follow-up support frame 20 is located below the movable support frame 10. In particular, in the case of multiple movable support frames 10, the follow-up support frame 20 is located below the lowermost movable support frame 10. That is, the follow-up support frame 20 belongs to the bottom layer of the tobacco clip placing frame arranged inside the curing barn.

[0046] On this basis, in order to facilitate manual placement of the tobacco clip on the movable support frame 10 at a higher position, or to take down the tobacco clip on the movable support frame 10 at a higher position, the loading and unloading system disclosed by the utility model can also include a lifting drive assembly 30.

[0047] Among them, the lifting drive assembly 30 is used to output reciprocating motion in the height direction, and each movable support frame 10 is connected to the output end of the lifting drive assembly 30, so as to drive each movable support frame 10 to move in the height direction reciprocally synchronously by the lifting drive assembly 30.

[0048] It can be understood that by setting the movable support frame 10 in the form of reciprocating movement along the height direction, the relevant personnel can conveniently adjust the height of the movable support frame 10 as needed, so as to quickly and labor-savingly place the tobacco clip on the corresponding movable support frame 10 or take the tobacco clip on the corresponding movable support frame 10. This design not only can reduce the labor intensity and improve the work efficiency for handling the tobacco clip at a higher position, but also can help to reduce the safety hidden danger caused by climbing operation by manual.

[0049] Meanwhile, as shown in Figures 1 to 3 , the loading and unloading system disclosed in the embodiment of the utility model can also include a plurality of connecting assemblies 40. The plurality of connecting assemblies 40 are used to connect the movable support frames 10 and the follow-up support frame 20, so that the movable support frames 10 are synchronously reciprocated along the height direction to be lifted and lowered, and the follow-up support frame 20 can be lifted and lowered along with the movable support frames 10, so that the movable support frames 10 can be lowered to a lower position.

[0050] Specifically, the connecting assembly 40 can include a connecting piece 41 and a limiting piece 42 corresponding to each movable support frame 10.

[0051] The connecting piece 41 can be a rod-shaped piece extending along the height direction as shown in Figure 3 . The bottom end of the connecting piece 41 can be fixedly connected with the follow-up support frame 20, the top end of the connecting piece 41 extends along the height direction and sequentially passes through each movable support frame 10, and the connecting piece 41 and each movable support frame 10 can be slidably connected.

[0052] The limiting piece 42 is fixedly connected to the connecting piece 41 and cooperates with the movable support frame 10, and is used to realize the linkage between the follow-up support frame 20 and the movable support frame 10, so that the follow-up support frame 20 can be lifted and lowered along with the movable support frame 10 under the action of the connecting assembly 40, for example, the limiting piece 42 can be a limiting nut supported at the top end of the corresponding movable support frame 10.

[0053] Based on the above setting, it is assumed that in the initial state, each movable support frame 10 is located at a higher position in the height direction, at this time, the limiting piece 42 corresponding to each movable support frame 10 is supported at the top end of the corresponding movable support frame 10 to limit the connecting piece 41, so as to avoid the connecting piece 41 along with the follow-up support frame 20 from falling under the action of gravity. At this time, the follow-up support frame 20 is located at a higher position from the ground under the action of the connecting piece 41.

[0054] On this basis, when each movable support frame 10 is synchronously lowered under the driving of the lifting driving assembly 30, due to the sliding fit between the connecting piece 41 and each movable support frame 10, as each movable support frame 10 continuously synchronously lowers, the connecting piece 41 together with the follower support frame 20 will be lowered under the action of gravity until the follower support frame 20 is lowered to the position as shown in the figure supported on the ground. Thereafter, each movable support frame 10 can continue to be lowered under the driving of the lifting driving assembly 30, and in theory, the lowermost movable support frame 10 can be lowered to infinitely approach the follower support frame 20 supported on the ground, or even be supported on the follower support frame 20. This design helps each movable support frame 10 to be synchronously lowered to a lower position. Figure 1

[0055] On the contrary, when each movable support frame 10 is synchronously raised under the driving of the lifting driving assembly 30, after each movable support frame 10 is raised to abut against the corresponding limiting piece 42, as each movable support frame 10 continues to rise, each movable support frame 10 can push the corresponding limiting piece 42, thereby lifting the connecting piece 41 together with the follower support frame 20 until each movable support frame 10 is raised to a predetermined height position.

[0056] It can be understood that by allowing the follower support frame 20 to rise and fall with each movable support frame 10, not only does each movable support frame 10 enable to be lowered to a lower position, but also compared with the way of separately providing a lifting driving device for the follower support frame 20, the cost is reduced, the time required for separately adjusting the position of the follower support frame 20 is reduced, and the efficiency is improved.

[0057] In some embodiments, as shown in Figure 1 , the lifting driving assembly 30 for driving the movable support frame 10 to lift can include a plurality of lifting driving units 31, each of which is used to output reciprocating motion in the height direction, and the plurality of lifting driving units 31 are connected to different positions of each movable support frame 10.

[0058] For example, the drawings of the utility model show a case including seven lifting driving units 31. Among them, in combination with the foregoing description, in the case where each movable support frame 10 includes three support plates 11 arranged in the horizontal direction in sequence and at intervals, as shown in Figure 3 , each support frame can further include a connecting plate 12 for connecting the three support plates 11, and the connecting plate 12 of each support frame can be located at the innermost side of the curing barn to optimize the structural design of the entire loading and unloading system. At this time, the seven lifting driving units 31 can be arranged in the following manner:

[0059] In combination with Figure 1 ​As shown, three of the seven lifting drive units 31 can be arranged on the left side of the drying oven, and these three lifting drive units 31 are arranged sequentially at intervals along the depth direction of the drying oven. At the same time, the output ends of these three lifting drive units 31 are connected to the support plates 11 on the left side of each movable support frame 10. Correspondingly, the other three of the seven lifting drive units 31 can be arranged on the right side of the drying oven, and these three lifting drive units 31 are also arranged sequentially at intervals along the depth direction of the drying oven. At the same time, the output ends of these three lifting drive units 31 are connected to the support plates 11 on the right side of each movable support frame 10. The last of the seven lifting drive units 31 can be arranged on the front side of the drying oven, that is, near the door of the drying oven, and the output end of this lifting drive unit 31 is connected to the support plate 11 in the middle of each movable support frame 10.

[0060] Thus, when the seven lifting drive units 31 synchronously output reciprocating motion along the height direction, the multiple movable support frames 10 can be raised and lowered synchronously. This design helps to improve the stability and reliability of the multiple movable support frames 10 when they are raised and lowered synchronously, and realizes the rational use of the limited space in the baking room, thereby improving the space utilization rate.

[0061] In some embodiments, multiple connecting components 40 can be configured to connect each movable support frame 10 to the follower support frame 20, and these multiple connecting components 40 can be distributed at different positions between each movable support frame 10 and the follower support frame 20 to improve the reliability of the follower support frame 20 when it moves with the movable support frame 10.

[0062] In some embodiments, such as Figure 4 As shown, each lifting drive unit 31 may include a threaded rod 311 and a movable seat 312. The threaded rod 311 extends along the height direction and is used to output rotational motion about its own axis. The movable seat 312 can slide freely along the height direction. For example, a slide rail 313 extending along the height direction and slidably connected to the movable seat 312 can be provided on the side of the movable seat 312 to allow the movable seat 312 to slide along the height direction. Furthermore, the movable seat 312 is threadedly connected to the threaded rod 311, and the movable seat 312 serves as the output end of the lifting drive unit 31; that is, each movable support frame 10, specifically, has its support plate 11 connected to the movable seat 312.

[0063] Thus, when the threaded rods 311 of the multiple lifting drive units 31 rotate synchronously, the movable seats 312 of the multiple lifting drive units 31 will move synchronously along the height direction, thereby causing the support plate 11 in the movable support frame 10 to move synchronously along the height direction, thus achieving the purpose of raising and lowering the movable support frame 10. Since the multiple movable support frames 10 are all connected to the output ends of the multiple lifting drive units 31, the multiple movable support frames 10 will rise and fall synchronously.

[0064] Further, with reference to the Figure 4 , each lifting driving unit 31 can further include a column 314 fixedly arranged in the curing barn. The threaded rod 311 is rotatably arranged on the column 314, thereby providing a carrier for the installation of the threaded rod 311. The sliding rail 313 described above can also be installed on the column 314.

[0065] In some embodiments, in the case of multiple lifting driving units 31, with reference to Figure 1 , the lifting driving assembly 30 can further include a power unit 32 and a transmission unit 33. The power unit 32 is transmissionally connected to one of the lifting driving units 31, for example, the threaded rod 311 of the lifting driving unit 31 near the door of the curing barn, so as to drive the threaded rod 311 transmissionally connected to the power unit 32 to rotate by the power unit 32. The power unit 32 can include a motor transmissionally connected to the corresponding threaded rod 311.

[0066] Meanwhile, the threaded rods 311 of two adjacent lifting driving units 31 can be transmissionally connected by means of the transmission unit 33, so that the threaded rods 311 of the multiple lifting driving units 31 can be synchronously rotated. For example, the transmission unit 33 can be a gear transmission mechanism including a transmission shaft 331, and in particular, a worm gear transmission mechanism including a transmission shaft 331.

[0067] Among them, the lifting driving unit 31 transmissionally connected to the power unit 32 can be regarded as a driving lifting unit, and the remaining lifting driving units 31 can be regarded as driven lifting units.

[0068] In this way, when the power unit 32 drives the threaded rod 311 transmissionally connected thereto, i.e., the threaded rod 311 of the driving lifting unit rotates, the threaded rods 311 of the remaining lifting driving units 31, i.e., the threaded rods 311 of the driven lifting units, will synchronously rotate, thereby enabling the multiple lifting driving units 31 to synchronously output reciprocating motion in the height direction. This design realizes that only one power unit 32 as a power source is provided to power the multiple lifting driving units 31, effectively reducing the cost of the loading and unloading system. At this time, a control unit 34, for example, a control box, as shown in Figure 1 , in communication connection with the power unit 32 can be arranged at the lifting driving unit 31 provided with the power unit 32, thereby conveniently controlling the power unit 32 to work, and thereby conveniently controlling the multiple movable support frames 10 to synchronously lift.

[0069] And, the lifting driving assembly 30 adopting the above design, specifically, the lifting driving unit 31 comprising the threaded rod 311 and the transmission unit 33 in the form of the worm gear transmission mechanism, makes each movable support frame 10 not suddenly drop when the loading and unloading system fails or other unexpected situations occur, compared with the scheme of adopting the traction mechanism composed of traction ropes and other components to realize the lifting of the movable support frame 10, effectively improves the reliability of the whole loading and unloading system.

[0070] In some embodiments, as shown in Figure 5 The lifting driving assembly 30 can also comprise a protective cover 35 corresponding to each lifting driving unit 31.

[0071] The protective cover 35 can protect the lifting driving unit 31, prolong the service life of the related components in the lifting driving unit 31, and help improve the appearance of the whole loading and unloading system.

[0072] In some embodiments, the loading and unloading system can also comprise a limiting assembly (not shown in the figure). The limiting assembly can comprise a first limiting switch and a second limiting switch arranged in order from top to bottom along the height direction, the first limiting switch being used to limit the upper limit position when the movable support frame 10 rises, and the second limiting switch being used to limit the lower limit position when the movable support frame 10 descends.

[0073] The limiting assembly can limit the movement stroke of the movable support frame 10 when it rises and descends, and improve the reliability of the whole loading and unloading system when it operates.

[0074] Further, the limiting assembly can be used in cooperation with an alarm device, such as an audible and visual alarm, so that when the movable support frame 10 moves close to the upper limit position or the lower limit position, the alarm device can issue a warning to remind the relevant personnel to control the movable support frame 10 to stop moving in time, so as to avoid unnecessary accidents.

[0075] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
