When the feeding mechanism 3 works, at the moment, the medical intermediate is fed at the feeding hole of the feeding pipe 301, first, the first motor 302 is started through the control module 7, the first motor 302 drives the first rotating shaft 303 and the first straight gear 304 to start rotating, the first straight gear 304 is meshed with the rack of the push rod 305 to push the telescopic push block assembly 308 to start moving backwards, the first motor 302 drives the blocking mechanism 5 to open, the telescopic push block assembly 308 pushes the first stop plate 306 to push the material backwards, in the process of pushing the material backwards, the first stop plate 306 blocks the feeding hole of the feeding pipe 301, the telescopic push block assembly 308 pushes the medical intermediate backwards to the discharging hole of the feeding pipe 301, the medical intermediate enters the feeding mechanism 6 from the discharging hole of the feeding pipe 301, in the process of pushing the material backwards of the feeding pipe 301, the telescopic push block assembly 308 pushes the medical intermediate to sequentially pass through the fixed feeding amount section, the feeding section and the discharging hole section, wherein the pipe diameter of the fixed feeding section is the same as that of the feeding port section, the purpose of the fixed feeding section is to avoid the direct scattering of the rear medical intermediate in the pushing process, so that the medical intermediate continuously falls from the feeding port of the feeding pipe 301, the amount of the medical intermediate once entering the feeding pipe 301 is uncontrollable, and the amount of the finally added medical intermediate is influenced, therefore, after the feeding port of the feeding pipe 301 is completely sealed, the medical intermediate enters the feeding section, the feeding section arranged in a downward inclination way enables the medical intermediate to have more sliding space, because the vibration feeding mode adopted to avoid uneven feeding in the feeding process enables the medical intermediate entering the feeding pipe 301 to become more densely distributed, in the longer pushing course, the medical intermediate distribution can increase the pushing resistance, and after a downward inclined plane is arranged, the medical intermediate can freely slide downwards and scatter along with the vibration feeding mode, the pushing process of the front telescopic push block assembly 308 is easier and is not easy to block, and the front telescopic push block assembly directly enters the discharge port section from the obliquely arranged feeding section, so that the waste of medical intermediates is reduced, and the retraction process of the telescopic push block assembly 308 is facilitated.
As shown in fig. 3 and 5, the retractable push block assembly 308 includes a push block housing 3081, a first sliding baffle 3082, a second sliding baffle 3083, a fixing rod 3084, a first spring 3085 and a second spring 3086, the push block housing 3081 is slidably disposed in the middle rear portion of the feeding pipe 301, the first sliding baffle 3082 is slidably disposed in the middle portion of the push block housing 3081, the second sliding baffle 3083 is slidably disposed in the rear side of the push block housing 3081, the lower ends of the first sliding baffle 3082 and the second sliding baffle 3083 are both obliquely disposed, the oblique angle is the same as that of the front portion of the feeding pipe 301, the rear portion of the first sliding baffle 3082 is fixedly connected with the three fixing rods 3084, two first springs 3085 are disposed between the first sliding baffle 3082 and the inner upper surface of the push block housing 3081, each fixing rod 3084 is wound with the second spring 3086, and the second springs 3086 are in close contact with the first sliding baffle 3082 and the second sliding baffle 3083.
In order to ensure that the medical intermediate obtains enough thrust and sealing effect in the obliquely arranged feeding section, the second spring 3086 is always in a compressed state, the first sliding baffle 3082 and the second sliding baffle 3083 are arranged to slide and pop up, after the telescopic push block assembly 308 enters the oblique feeding section of the feeding pipe 301, the second spring 3086 firstly pushes the second sliding baffle 3083 on the rear side to slide downwards, then the first sliding baffle 3082 contacts the inclined surface, the first sliding baffle 3082 slides downwards under the pressure of the first spring 3085, the extended second spring 3086 is compressed again through the downward sliding of the first sliding baffle 3082, so that enough thrust is provided to ensure that the second sliding baffle 3083 is always in close contact with the inner lower surface of the feeding pipe 301, and good sealing effect is realized, because the first sliding baffle 3082 and the second sliding baffle 3083 mainly have the function of matching with the inclined surface of the oblique feeding section to push the medical intermediate, the inclined arrangement of the lower ends of the first and second slide guards 3082 and 3083 effectively reduces the contact area, thereby reducing the resistance of the telescopic ram assembly 308 at the feed opening section and the fixed feed amount section.
As shown in fig. 1 and 6, the vibration mechanism 4 includes four vibration plates 401, four vibration frames 402, a first connecting rod 403, rubber hammers 404 and limiting rods 405, the four vibration plates 401 are respectively and fixedly connected to the outer surface of the lower portion of the storage bin 1, the vibration plates 401 are electrically connected to the control module 7, the vibration frames 402, the first connecting rods 403, the rubber hammers 404 and the limiting rods 405 are equal in number to the feeding pipes 301, the vibration frames 402 are slidably disposed at the rear ends of the push rods 305, through holes are disposed on the left and right side surfaces of the vibration frames 402, the first connecting rods 403 are respectively and slidably disposed in the through holes of the vibration frames 402, the rubber hammers 404 are respectively and fixedly connected to two ends of the first connecting rods 403, two limiting rods 405 are fixedly connected to the upper surface of the vibration frames 402, and the limiting rods 405 are slidably disposed in the bending chutes of the partition layers of the feeding pipes 301.
Because the medical intermediate used for the subsequent reaction is powdery, the process of self-feeding the medical intermediate and the feeding amount are not controllable, and the medical intermediate can be adhered to the feeding pipe 301 and the telescopic push block assembly 308 in the feeding process, the vibration mechanism 4 is used for accelerating and quantifying the feeding process, and simultaneously the waste and the adhesion condition of the medical intermediate feeding process are reduced, firstly, the vibration plate 401 is controlled by the control module 7 to start vibration to accelerate the feeding process of the medical intermediate, because the distribution density of the medical intermediate powder can change along with the vibration time, the vibration duration of the vibration plate 401 is controlled to ensure that the feeding amount is the same each time, and the vibration frame 402, the first connecting rod 403, the rubber hammer 404 and the limiting rod 405 which are assembled at the rear end of the feeding mechanism 3 are responsible for vibration cleaning of the medical intermediate adhered to the inner wall of the feeding pipe 301 and the telescopic push block assembly 308 in the feeding process, in the process of backward movement of the feeding mechanism 3, the limiting rod 405 is limited by the bent sliding groove, so that the vibration frame 402 moves left and right at the front end of the push rod 305, in the process of left and right movement of the vibration frame 402, the vibration frame 402 drives the rubber hammer 404 to move in the same direction, the first connecting rod 403 slides left and right in the through hole of the vibration frame 402, the rubber hammer 404 collides left and right between the front inner walls of the feeding pipe 301 of the push rod 305, vibration is transmitted backward through the feeding pipe 301 and the push rod 305, and the medical intermediate adhered to the inner wall of the feeding pipe 301 and the telescopic push block assembly 308 is cleaned by vibration.
