Furthermore, the first placing plate 5 can be set to be one or more than one, the number of the selection mechanism and the number of the circulation mechanism correspond to the number of the spiral pushing rings 6, and the selection mechanism and the circulation mechanism are correspondingly set, the refrigeration box body 1 can be designed to be wide, a plurality of spiral pushing rings 6 are arranged in the refrigeration box body, so that a plurality of rows of packaging medicine bottles 8 can be placed, and the utilization rate of the refrigeration box body 1 is improved.

Further, a guide plate 23 is fixedly installed at the inner bottom of the refrigerating box body 1, a circular through groove is formed in the guide plate 23, the packaged medicine bottle 8 falls on the second placing plate 19 after passing through the circular through groove of the guide plate 23, the size of the circular through groove is matched with that of the packaged medicine bottle 8, the circular through groove is positioned right above the second placing plate 19 and is also positioned between the spiral propelling rings 6, the packaged medicine bottle 8 is pushed to the circular through groove and vertically falls under the guide of the circular through groove, the distance between the lowest point of the circular through groove and the highest point of the spiral propelling ring 6 is designed to be smaller than the height of the packaged medicine bottle 8, when the medicine bottle in the circular through groove is about to fall, if the spiral propelling ring 6 is not in the interval capable of bearing the packaged medicine bottle 8 at the moment, but when the spiral propelling ring 6 blocks the packaged medicine bottle 8, the packaged medicine bottle 8 cannot fall down and continuously rotates along with the spiral propelling ring 6, when no longer blocking encapsulation medicine bottle 8, the interval of placing has appeared promptly, and encapsulation medicine bottle 8 can receive gravity to fall to the second and place on the board 19 this moment, and be in between spiral propulsion ring 6, can be promoted the removal afterwards, and another kind of condition is, encapsulation medicine bottle 8 just directly falls between the interval of spiral propulsion ring 6.

Further, be provided with initiative transfer roller 24 on the transmission slide 20, this initiative transfer roller 24 passes through external power drive, can carry out the switching by oneself, and the quantity of encapsulation medicine bottle 8 on transmission slide 20 is too little, and when unable the encapsulation medicine bottle 8 of arranging at the forefront promoted first placing on the board 5, can start this initiative transfer roller 24, and initiative transfer roller 24 rotates and to realize initiatively conveying the end to transmission slide 20 with encapsulation medicine bottle 8, finally drops on first placing on the board 5.

In addition, funnel-shaped flexible teeth can be arranged on the lower edge of the circular groove 21, so that the falling of the packaged medicine bottle 8 can be buffered, the packaged medicine bottle 8 can be protected,

the working principle is as follows: when the refrigeration equipment is used, the placing port 2 can be opened and closed, the packaged medicine bottles 8 can be placed on the first placing plate 5 after being opened, then the first placing plate 5 is closed, the semiconductor refrigerating sheet 7 is used for refrigerating the interior of the refrigeration box body 1, the required temperature is provided for refrigeration of the packaged medicine bottles 8, the packaged medicine bottles 8 are placed on the first placing plate 5 in a sliding mode and are arranged at intervals among the spirals of the spiral propelling ring 6, the rotating ring 4 is arranged at the left end of the spiral propelling ring 6 and drives the spiral propelling ring 6 to rotate, and the spiral propelling ring 6 gradually propels the packaged medicine bottles 8 to the right under the spiral propelling effect after the spiral propelling ring 6 is rotated by the rotating ring 4;

when a specific packaged medicine bottle 8 needs to be taken out, the packaged medicine bottle 8 at the rightmost end is pushed by the spiral pushing ring 6, the packaged medicine bottle 8 at the rightmost end is pushed to fall on the selection mechanism, a worker observes the medicine bottle falling on the selection mechanism, if the packaged medicine bottle 8 needs to be taken out by the worker, the required packaged medicine bottle 8 can be taken out through the selection mechanism, the movable door 16 is pulled rightwards, the movable door shown in figure 1 is at a position a, the position a is a position where the sealing strip 25 and the sealing frame 31 can be tightly attached to each other, the movable door 16 at the position a drives the connecting rod 15 to move rightwards, the position b is a position where the movable door 16 moves rightwards, when the connecting rod 15 slides rightwards, the inclined groove plate 14 fixedly connected with the connecting rod is driven to slide rightwards, the inclined groove on the inclined groove plate 14 acts on the two cylindrical bosses 12, the left cylindrical lug 12 moves upwards, the right cylindrical lug 12 moves downwards, the left lifting rod 11 moves upwards, the right lifting rod 11 moves downwards, finally the movable plate 13 inclines rightwards, the packaged medicine bottles 8 on the movable plate 13 slide onto the receiving drawer 17, the inner bottom of the receiving drawer 17 also inclines rightwards downwards, at the moment, a worker can take out the packaged medicine bottles 8 through the opened movable door 16, and in the process of setting the movable door 16 from the position a to the position b, the two spiral pushing rings 6 stop rotating;

if the packaged medicine bottle 8 falling on the selection mechanism is not needed, but needs to be selected next or arranged behind, the packaged medicine bottle 8 can be conveyed to the circulation mechanism through the selection mechanism, the circulation mechanism can return the packaged medicine bottle 8 to the spiral space of the spiral propelling ring 6 on the first placing plate 5, so that the packaged medicine bottle 8 can be selected later, only when the packaged medicine bottle 8 needing to be selected is taken out in the whole process, a small opening is formed in the refrigerating box body 1, the leakage of cold air is greatly reduced, and the phenomenon that other packaged medicine bottles 8 are affected by the external environment in order to take out a certain packaged medicine bottle 8 can also be avoided.

When the movable door 16 is pushed leftwards and pushed to the position c, the driving sources of the two spiral pushing rings 6 drive the movable door 16 to rotate at the same time, the position c refers to the maximum position of the movable door 16 moving leftwards, when the packaged medicine bottles 8 are pushed onto the conveying slide way 20, the gradually pushed packaged medicine bottles are accumulated on the conveying slide way 20 to be arranged, and each time the spiral pushing ring 6 below is transferred onto the conveying slide way 20, the packaged medicine bottles 8 arranged in front are pushed forwards for a certain distance and finally reach the tail end of the conveying slide way 20 one by one, and fall back onto the first placing plate 5 through the circular groove 21. When the number of the internal sealed medicine bottles is too small and circulation cannot be formed, the driving conveying roller 24 can be started, the driving conveying roller 24 rotates to convey the sealed medicine bottles 8 to the tail end of the conveying slide way 20, and finally falls onto the first placing plate 5 to form circulation. In addition, the movable plate 13 is provided with a protruding strip at a position close to the front end and not at the front end, so that improper sliding in the process of opening the small door into the drawer can be prevented, and the sliding in the drawer can be prevented in the process of opening the large door.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
