[0030] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0031] like Figure 1-4 As shown, a device for quickly raising and lowering tobacco flue-curing is provided, comprising a pre-loading assembly 2 and a bed-raising assembly arranged on a base 1, and a plurality of universal wheels 11 are arranged at the lower end of the base 1.

[0032] The pre-loading assembly 2 includes a first conveying assembly 21; the first conveying assembly 21 has two and is symmetrically arranged on the base 1; the first conveying assembly 21 includes a first bracket 211 arranged on the base 1 and a first conveyor belt 212 connected to the first bracket 211 through a first pulley 213. In this embodiment, the first conveyor belts 212 on both sides have the same and synchronous movement direction and speed, and can be driven and rotated separately by the same driving device or by different driving devices. The first conveyor belt 212 can be a belt transmission or a chain transmission, and the corresponding first pulley 213 is a pulley or a sprocket, including a tensioning wheel to ensure that it is always in a tensioned state.

[0033] The upper end of the first conveyor belt 212 is the first carrying end 212a, and the two ends of the cigarette clip are respectively overlapped on the first carrying ends 212a of the two symmetrically arranged first conveyor belts 212. A first support track 214 is arranged below the first carrying end 212a, and the first support track 214 is fixedly connected to the first bracket 211. When the first conveyor belt 212 is in operation, the lower end of the first carrying end 212a is slidably connected to the first support track 214, and the first support track 214 plays a supporting role to ensure that when the cigarette clip is overlapped on the first carrying end 212a, it can be stably supported to prevent the first carrying end 212a from collapsing.

[0034] The pre-loading assembly 2 includes a first material blocking assembly 22 arranged on the first bracket 211, and at least two first material blocking assemblies 22 are provided and are respectively connected to the two ends of the first conveyor belt 212. The first material blocking assembly 22 includes a first driving device 221 and a first material blocking plate 222 connected to the first bracket 211, and the first material blocking plate 222 can move downward to above the first loading end 212a under the drive of the first driving device 221. When going up to the kang, the operator or the transfer mechanism transfers the cigarette clips holding the tobacco leaves to the first conveyor belt 212 one by one, and the two ends of the cigarette clips are overlapped on the two first loading ends 212a. In order to further improve the production efficiency, it is necessary to automatically transfer the cigarette clips to the downward end of the first conveyor belt 212 so that multiple cigarette clips can be placed on the first conveyor belt 212. A first sensor 223 can be respectively set at both ends of the first conveyor belt 212. When the first sensor 223 at the lower end senses a cigarette clip, the first baffle plate 222 moves downward to the first loading end 212a under the drive of the first driving device 221 to block the cigarette clip from continuing to be conveyed. At this time, the cigarette clip and the first conveyor belt 212 are in a sliding contact connection; when the first sensor 223 at the upper end of the first conveyor belt 212 senses a cigarette clip, it means that the cigarette clips on the first conveyor belt 212 are saturated and need to be transferred to the upper bed assembly. It should be noted that the cigarette clips placed on the pre-loading assembly 2 do not necessarily have to be completely saturated before being transferred to the upper bed assembly, and the transfer and transmission can be adjusted according to the actual operation rhythm.

[0035] The upper bed assembly includes a second conveying assembly 3, and the second conveying assembly 3 is connected to the base 1 through a lifting assembly 4. The second conveying assembly 3 can move in a vertical direction under the drive of the lifting assembly 4 and is connected to the first conveying assembly 21. The second conveying assembly 3 and the lifting assembly 4 are both symmetrically arranged at two locations.

[0036] The second conveying assembly 3 includes a second bracket 31 connected to the lifting assembly 4. The second bracket 31 is connected to a second conveyor belt 33 through a second pulley 32. The second conveyor belt 33 and the first conveyor belt 212 are on the same vertical plane. The upper end of the second conveyor belt 33 is a second carrying end 33a. When the cigarette clip is transferred from the pre-loading assembly 2 to the second conveying assembly 3, its two ends are respectively overlapped on two symmetrical second carrying ends 33a. A second support rail 332 is arranged below the second carrying end 33a, and the second support rail 332 is fixedly connected to the second bracket 31. In this embodiment, the second conveying assembly 3 moves in the vertical direction under the drive of the lifting assembly 4. Its movement path passes through the plane where the first carrying end 212a is located, that is, when the second conveying assembly 3 moves to a certain position, the second carrying end 33a and the first carrying end 212a are on the same plane, and the cigarette clip on the first carrying end 212a can be directly transferred to the second carrying end 33a through the rotation of the first conveyor belt 212 and the second conveyor belt 33.

[0037] The second conveyor belts 33 on both sides can be driven to rotate by the same driving device, or can be driven to rotate by two driving devices respectively, but the rotation speed and movement direction of the two are the same and synchronous. The second conveyor belt 33 can be a belt or a chain, etc., and the corresponding second pulley 32 is a pulley or a sprocket, including a tensioning wheel to ensure that the second conveyor belt 33 is always in a tensioned state. When the second conveyor belt 33 rotates, the lower end of the second carrying end 33a is slidably connected to the second support rail 332 to avoid the second carrying end 33a collapsing when conveying the cigarette clips, thereby affecting the stability of the conveying.

[0038] The second conveying assembly 3 includes a second material blocking assembly 34 disposed on the second bracket 31, and there are at least two second material blocking assemblies 34, which are respectively disposed at both ends of the second conveyor belt 33. The second material blocking assembly 34 includes a second driving device 341 connected to the second bracket 31 and a second material blocking plate 342 connected to the second driving device 341, and the second material blocking plate 342 can move downward to above the second loading end 33a under the drive of the second driving device 341. In this embodiment, second sensors 343 can be respectively disposed at both ends of the second conveyor belt 33, so that before the second conveying assembly 3 is aligned with the rack of the tobacco curing room, the second material blocking plate 342 at the lower end of the second conveyor belt 33 is driven by the second driving device 341 to extend, blocking the passage of the cigarette clips, so as to avoid accidents such as the cigarette clips falling.

[0039] The lifting assembly 4 is provided at two locations and symmetrically arranged on the base 1, and includes a third bracket 41 connected to the base 1, and a vertical guide rail 42 is provided on the third bracket 41, and the second bracket 31 is connected to the third bracket 41 through the guide rail 42. A third conveyor belt 43 with a vertical conveying direction is provided on the third bracket 41, and one end of the third conveyor belt 43 is connected to the second bracket 31, so that when the third conveyor belt 43 rotates, it can drive the second bracket 31 to move along the guide rail 42. In this embodiment, the third conveyor belts 43 on both sides can be driven by the same driving device at the same time or by different driving devices respectively, but the two have the same movement direction and rotation speed, and move synchronously. When the third conveyor belt 43 rotates, it drives the second bracket 31 to move along the guide rail 42, so that the second carrying end 33a is connected to the first carrying end or to the rack in the tobacco curing room. The third bracket 41 is provided with a plurality of third sensors (not shown in the figure) in the vertical direction, and the third conveyor belt 43 is provided with a sensing sheet (not shown in the figure) connected to the third sensor, and each third sensor corresponds to a different layer height of the shelf in the tobacco curing room. When the lifting component 4 is in operation and the third sensor senses the sensing sheet, it means that the second feeding component 3 is lifted or lowered to a specified height, and the upper tobacco clip can be transferred to the shelf in the tobacco curing room through the second conveyor belt 33. It should be noted that the position of the third sensor in the vertical direction can be adjusted to suit different layer heights of the shelf.

[0040] When getting off the kang, the first conveyor belt and the second conveyor belt 33 rotate in opposite directions, and the actions performed by the kang-entering assembly and the pre-loading assembly 2 are similar to those when getting on the kang, and will not be described in detail here.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
