Description

Technical Field

[0001] This utility model relates to a mobile structure, specifically a mobile shelf structure built into a freeze-drying warehouse, belonging to the field of food processing technology. Background Technology

[0002] Vacuum freeze drying utilizes the principle of sublimation under vacuum conditions to remove moisture from pre-frozen food by sublimating it directly into water vapor without melting the ice. Compared to air drying and dehydration techniques, the biggest advantage of freeze-dried food is that it retains the color, aroma, flavor, shape, and nutritional components of the original food. The freeze-drying chamber provides the necessary environment for freeze drying and is equipped with shelves inside to store freeze-dried food.

[0003] While existing freeze-drying silos with built-in shelves allow for layered storage of materials, preventing mutual compression and collision and reducing breakage during storage and transportation, and while the environment inside a freeze-drying silo is typically low-temperature and low-humidity, the built-in shelves ensure sufficient contact between the materials and the air inside the silo, guaranteeing the drying effect and preventing moisture absorption and spoilage, and while the built-in shelves make material storage more organized and facilitate monitoring and management of material quantity, quality, and storage time, allowing for timely detection and handling of problems, the built-in shelves in freeze-drying silos generally cannot be moved out of the silo, hindering food retrieval and slowing down operational efficiency. Therefore, we provide a movable structure for the built-in shelves of a freeze-drying silo to solve these problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a movable shelf structure built into a freeze-drying warehouse. The specific technical solution is as follows:

[0005] A movable shelf structure with an internal structure for a freeze-drying chamber includes a freeze-drying chamber. A movable mechanism is installed inside the freeze-drying chamber. The movable mechanism includes a sliding frame and a sliding block. The sliding frame has a sliding cavity and a first through hole. The sliding block has a first threaded hole. A servo motor is fixedly mounted on the sliding frame. The output end of the servo motor is fixedly connected to a first threaded rod. A movable plate is fixedly connected to the sliding block. Two symmetrical first roller groups are fixedly mounted on the movable plate. The movable plate has two symmetrical second through holes. Each of the two second through holes is fixedly connected to a telescopic cylinder. The telescopic cylinder has a third through hole. A sliding rod is slidably connected to the telescopic cylinder. A second roller group is fixedly mounted on the sliding rod. The sliding rod has a second threaded hole. A second threaded rod is threadedly connected to the second threaded hole. A rotating disk is fixedly connected to the second threaded rod.

[0006] Preferably, the sliding block is slidably connected to the sliding cavity, the first threaded rod is rotatably connected to the sliding cavity, and the first threaded rod is rotatably connected to the first through hole.

[0007] Preferably, the first threaded rod is threadedly connected to the first threaded hole, the second threaded rod is rotatably connected to the third through hole, and the rotating disk is rotatably connected to the telescopic cylinder.

[0008] Preferably, the freeze-drying chamber is fixedly connected to a first support plate, and the first support plate is fixedly connected to the sliding frame.

[0009] Preferably, the moving mechanism is provided with a shelf adjustment mechanism, which includes two sets of mutually symmetrical support columns and a set of equidistant second support plates. Both sets of support columns are fixedly connected to the moving plate, and both sets of support columns have a row of equidistant fourth through holes.

[0010] Preferably, each of the fourth through holes in a row is slidably connected to a third threaded hole, and a threaded post is provided in the fourth through hole and the third threaded hole. A threaded post is fixedly connected to a screw head. Each of the second support plates in a group is provided with multiple third threaded holes, and the third threaded holes are threadedly connected to the threaded post.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The built-in shelf moving structure of this freeze-drying chamber controls the servo motor to rotate clockwise, thereby driving the moving plate to move to the right. This moves the second roller group out of the freeze-drying chamber. When the second roller group is out of the freeze-drying chamber, the rotating disk is controlled to rotate, causing the second threaded rod to rotate inside the second threaded hole. Finally, the sliding rod slides downward inside the telescopic cylinder, simultaneously driving the second roller group to move downward. When the second roller group is supported on the ground, the rotating disk stops rotating, and then the servo motor is controlled to rotate clockwise, so that the shelf is completely moved out of the freeze-drying chamber. This achieves the purpose of this device to completely remove the shelf from the freeze-drying chamber.

[0013] 2. The built-in shelf moving structure of this freeze-drying chamber controls the threaded column to pass through the fourth through hole through the screw head, and then controls the threaded column to be threadedly connected to the third threaded hole, so that the shelf can be quickly assembled. By controlling the threaded column to pass through different fourth through holes, the spacing between multiple second support plates can be adjusted, thus realizing the purpose of this device to quickly adjust the shelf spacing.

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] Please see Figure 1 , Figure 2 , Figure 3 The system includes a freeze-drying chamber 1, inside which a moving mechanism 3 is installed. The moving mechanism 3 includes a sliding frame 301 and a sliding block 304. The sliding frame 301 has a sliding cavity 302 and a first through hole 303. The sliding block 304 has a first threaded hole 305. A servo motor 306 is fixedly installed on the sliding frame 301. The output end of the servo motor 306 is fixedly connected to a first threaded rod 307. A moving plate 308 is fixedly connected to the sliding block 304. The moving plate 308 has two mutually symmetrical first roller groups 309 fixedly installed. The moving plate 308 has two mutually symmetrical second through holes 310. Each of the two second through holes 310 is fixedly connected to a telescopic cylinder 311. The telescopic cylinder 311 has a third through hole 312. The telescopic cylinder 311 is slidably connected to a sliding rod 313. The sliding rod 313 is fixedly installed with a second roller assembly 314. The sliding rod 313 has a second threaded hole 315. The second threaded hole 315 is threadedly connected to a second threaded rod 316. The second threaded rod 316 is fixedly connected to a rotating disk 317. The sliding block 304 is slidably connected to the sliding cavity 302. The first threaded rod 307 is rotatably connected to the sliding cavity 302. The first threaded rod 307 is rotatably connected to the first through hole 303. The first threaded rod 307 is threadedly connected to the first threaded hole 305. The second threaded rod 316 is rotatably connected to the third through hole 312. The rotating disk 317 is rotatably connected to the telescopic cylinder 311.

[0020] The servo motor 306 in this application is a common electrical device in the prior art. This application will not elaborate further on its model or internal structure, and it can be replaced by other power sources. The first roller assembly 309 and the second roller assembly 314 are both prior art and will not be described in detail. By controlling the servo motor 306 to rotate clockwise, the first threaded rod 307 is driven to rotate with the servo motor 306, thereby causing the first threaded hole 305 to slide to the right inside the sliding cavity 302. Simultaneously, the moving plate 308 is moved to the right, which can move the second roller assembly 314. When the second roller assembly 314 is removed from the outside of the freeze-drying chamber 1, the rotating disk 317 is controlled to rotate, causing the second threaded rod 316 to rotate inside the second threaded hole 315. This causes the sliding rod 313 to slide downward inside the telescopic cylinder 311, while simultaneously driving the second roller assembly 314 to move downward. When the second roller assembly 314 is supported on the ground, the rotating disk 317 is stopped, and then the servo motor 306 is controlled to rotate clockwise, so that the shelf is completely removed from the inside of the freeze-drying chamber 1, thus achieving the purpose of this device to completely remove the shelf from the freeze-drying chamber 1.

[0021] Please refer to it again. Figure 1 , Figure 2 , Figure 3 The freeze-drying chamber 1 is fixedly connected to a first support plate 2, which is fixedly connected to a sliding frame 301. The moving mechanism 3 is equipped with a shelf adjustment mechanism 4, which includes two sets of mutually symmetrical support columns 401 and a set of equidistant second support plates 405. Both sets of support columns 401 are fixedly connected to the moving plate 308. Both sets of support columns 401 have a row of equidistant fourth through holes 402. Each row of fourth through holes 402 is slidably connected to a third threaded hole 406. The threaded column 403 is fixedly connected to a screw head 404. Each set of second support plates 405 has multiple third threaded holes 406, which are threadedly connected to the threaded column 403.

[0022] The shape of the second support plate 405 here is determined according to the specific situation. The threaded post 403 is controlled to pass through the fourth through hole 402 by the screw head 404, and then the threaded post 403 is controlled to be threadedly connected to the third threaded hole 406, so that the shelf can be quickly assembled. By controlling the threaded post 403 to pass through different fourth through holes 402, the spacing between multiple second support plates 405 can be adjusted, thus realizing the purpose of this device to quickly adjust the shelf spacing.

[0023] In use, this invention works as follows: By controlling the servo motor 306 to rotate clockwise, the first threaded rod 307 rotates with the servo motor 306, thereby causing the first threaded hole 305 to slide to the right inside the sliding cavity 302. Simultaneously, the moving plate 308 moves to the right, moving the second roller assembly 314 out of the freeze-drying chamber 1. When the second roller assembly 314 is out of the freeze-drying chamber 1, the rotating disk 317 is controlled to rotate, causing the second threaded rod 316 to rotate inside the second threaded hole 315. Ultimately, this causes the sliding rod 313 to slide downwards inside the telescopic cylinder 311, simultaneously moving the second roller assembly 314 to the right. The device moves downwards, and when the second roller group 314 is supported on the ground, the rotating disk 317 stops rotating. Then, the servo motor 306 continues to rotate clockwise, so that the shelf is completely removed from the freeze-drying chamber 1, thus achieving the purpose of completely removing the shelf from the freeze-drying chamber 1. The threaded post 403 is controlled to pass through the fourth through hole 402 by the screw head 404, and then the threaded post 403 is controlled to be threadedly connected to the third threaded hole 406, so that the shelf can be quickly assembled. By controlling the threaded post 403 to pass through different fourth through holes 402, the spacing between multiple second support plates 405 can be adjusted, thus achieving the purpose of quickly adjusting the shelf spacing.
