DETAILED DESCRIPTION OF THE INVENTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0023] Please refer to Figures 1-5 As shown in the figure, the present invention provides a technical solution: a feeding device for a freeze dryer, including a machine body 1 and a plurality of mesh trays 2. The mesh trays 2 are all arranged in the machine body 1. A plurality of feeding ports 4 are opened on the left side of the machine body 1. Outer sealing plates 3 covering the left sides of the feeding ports 4 are fixed to the left ends of the mesh trays 2, and inner sealing plates 8 are fixed to the right ends of the mesh trays 2. Lead screws 6 and guide rails 7 are arranged below the mesh trays 2. Reversible motors 5 fixed to the outer side walls of the machine body 1 are arranged on the right sides of the inner sealing plates 8. One end of each lead screw 6 is rotatably connected to the left inner wall of the machine body 1, and the other end of the lead screw 6 rotates through the right side of the machine body 1 to the right. The power ends of the reversible motors 5 are respectively connected to the other ends of the adjacent lead screws 6. The inner sealing plates 8 are all threadedly sleeved on the adjacent lead screws 6. The guide rails 7 are all fixed in the machine body 1, and the inner sealing plates 8 are all slidably sleeved on the guide rails 7.

[0024] By respectively arranging the outer sealing plate 3 and the inner sealing plate 8 at the left and right ends of each mesh tray 2, when feeding into the machine body 1, start the corresponding reversible motor 5 to drive the corresponding lead screw 6 to rotate forward. The lead screw 6 will drive the inner sealing plate 8 to slide leftward along the guide rail 7. The inner sealing plate 8 will push the mesh tray 2 out of the machine body 1 through the feeding port 4 until the inner sealing plate 8 covers the feeding port 4. At this time, the mesh tray 2 is moved out of the machine body 1. Therefore, during the process of loading the mesh tray 2, during this period, since the inner sealing plate 8 temporarily covers the feeding port 4, the cold air in the machine body 1 can be reduced from leaking through the feeding port 4, thereby effectively reducing the power consumption of the freeze dryer and effectively ensuring the normal freezing efficiency of the freeze dryer.

[0025] In this embodiment, pull rings 13 are fixed to the right sides of the upper ends of the partition plates 11. A plurality of storage grooves 10 are opened at the upper ends of the mesh trays 2, and the partition plates 11 are hinged in the storage grooves 10.

[0026] Since multiple partition plates 11 are provided on each mesh tray 2, the partition plates 11 are in a flat state when not in use. At this time, it is convenient to place the same type of items on the mesh tray 2 for freeze-drying inside the machine body 1. When it is necessary to place various types of items on the same mesh tray 2, when the partition plates 11 are erected, the partition plates 11 can be pulled by the pull rings 13 to rotate counterclockwise and be erected. The operation is convenient and fast. After the partition plates 11 are vertically erected, various types of items are separated by the partition plates 11. Therefore, it is convenient to neatly place various types of items on the same mesh tray 2, avoiding the situation of clutter and confusion when various types of items are placed on the same mesh tray 2.

[0027] In this embodiment, rubber sealing gaskets 9 are connected to the right side of the outer sealing plate 3 and the left side of the inner sealing plate 8, and the outer sealing plate 3 and the inner sealing plate 8 are of equal size.

[0028] When the outer sealing plate 3 or the inner sealing plate 8 covers the feed inlet 4, the rubber sealing gasket 9 is in close contact with the machine body 1, which is beneficial to better ensure the sealing performance when the outer sealing plate 3 or the inner sealing plate 8 covers the feed inlet 4.

[0029] In this embodiment, magnet blocks 12 are inlaid on the left inner walls of the storage grooves 10, iron sheets 14 are inlaid on the left sides of the upper ends of the partition plates 11, and the magnet blocks 12 correspond to the iron sheets 14.

[0030] After the partition plates 11 are erected, the magnet blocks 12 just adsorb the iron sheets 14 at this time, thereby preventing the partition plates 11 from accidentally falling down after being erected. Moreover, when the partition plates 11 are not in use, the partition plates 11 can be directly rotated clockwise and stored in the storage grooves 10, and the operation is convenient.

[0031] In this embodiment, the power ends of the forward and reverse motors 5 are connected to the other ends of the adjacent lead screws 6, the inner sealing plates 8 are all threadedly sleeved on the adjacent lead screws 6, the guide rails 7 are all fixed inside the machine body 1, and the inner sealing plates 8 are all slidably sleeved on the guide rails 7.

[0032] After the mesh tray 2 is loaded, the forward and reverse motor 5 works to drive the lead screw 6 to reverse. The lead screw 6 will drive the inner sealing plate 8 to slide to the right along the guide rail 7, and the inner sealing plate 8 will pull the mesh tray 2 into the machine body 1 until the outer sealing plate 3 covers the feed inlet 4, achieving the effect of sealing the machine body 1, so as to facilitate the machine body 1 to perform freeze-drying treatment on the items on the mesh tray 2.

[0033] In this embodiment, a plurality of ultraviolet disinfection lamps 16 are connected to the inner side wall of the machine body 1.

[0034] By installing a plurality of ultraviolet disinfection lamps 16 on the inner side wall of the machine body 1, the ultraviolet disinfection lamps 16 are beneficial to eliminate bacteria propagules, spores, mycobacteria, coronaviruses, fungi, rickettsiae, chlamydia, etc. inside the machine body 1, and are beneficial to ensuring the hygiene inside the machine body 1.

[0035] Working principle:

[0036] When feeding materials into the machine body 1, start the corresponding forward and reverse motor 5 to drive the corresponding lead screw 6 to rotate forward. The lead screw 6 will drive the inner sealing plate 8 to slide left along the guide rail 7. The inner sealing plate 8 will push the mesh tray 2 out of the machine body 1 through the feeding port 4 until the inner sealing plate 8 covers the feeding port 4. At this time, the mesh tray 2 is moved out of the machine body 1. Therefore, during the process of loading materials onto the mesh tray 2, during this period, since the inner sealing plate 8 temporarily covers the feeding port 4, this can reduce the leakage of cold air in the machine body 1 from the feeding port 4. When various types of items need to be placed on the same mesh tray 2, when the partition 11 is erected, it can be rotated counterclockwise and erected by pulling the pull ring 13. The operation is convenient and fast. After the partition 11 is vertically erected, various types of items are separated by the partition 11. Therefore, it is beneficial to neatly place various types of items on the same mesh tray 2.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
