[0001] The invention relates to a self-unloading medicine stirring device. Background Art

[0002] During the pill production process, a feeding mechanism is required to transport pills within a certain range from one workstation to another. The existing pill feeding is generally carried out by conveyor belts. Since the pills are quantitatively transported each time, the quantitative pills cannot be well concentrated and positioned on the conveyor belt during the conveyor belt transportation process, so the transportation efficiency is very low. Summary of the invention

[0003] The present invention provides a self-unloading medicine stirring device in order to solve the problems existing in the above-mentioned prior art.

[0004] The technical solutions adopted in the present invention are:

[0005] A self-unloading medicine stirring device comprises a rotating frame, a driving plate, a discharge plate, a stirring barrel, a sealing cover and a torsion spring. A plurality of stirring barrels are evenly fixed in the circumferential direction of the rotating frame and rotate with the rotating frame. A sealing cover is provided on one side of each stirring barrel. The torsion spring is installed on the sealing cover. The elastic force of the torsion spring props up the sealing cover and makes the upper port of the stirring barrel in an open state. The driving plate and the discharge plate are both arranged on a rotating path of the sealing cover rotating with the rotating frame. When the sealing cover contacts the driving plate and moves in abutment with the driving plate, the driving plate covers the sealing cover on the stirring barrel and closes the upper port of the stirring barrel; when the sealing cover contacts the discharge plate and moves in abutment with the discharge plate, the discharge plate props up the sealing cover and makes the upper port of the stirring barrel open.

[0006] The cam is fixed to the top of the mounting plate and the support plate, and the ...

[0007] Further, an arc-shaped guiding groove is provided on the guiding plate, and a positioning through-hole is provided at the bottom end of the arc-shaped guiding groove. When the roller fits and drives the plate to move, the guiding column moves along the arc-shaped guiding groove. When the sealing cover is closed on the stirring barrel, the guiding column penetrates through the positioning through-hole.

[0008] Further, the arc-shaped guiding groove is arranged along the side surface of the guiding plate. The guiding surface A of the arc-shaped guiding groove in contact with the guiding column is a bevel structure, and the inclination direction of the guiding surface A inclines outward from the positioning through-hole at the bottom end towards the top end of the arc-shaped guiding groove.

[0009] Further, the positioning through-hole is communicated with the arc-shaped guiding groove, and the inner wall surface of the positioning through-hole is a conical surface structure.

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] like Figures 1 to 6 The present invention discloses a self-unloading medicine stirring device, comprising a rotating frame 11, a driving plate 21, a discharge plate 31, a stirring barrel 41, a sealing cover 51 and a torsion spring 61. The rotating frame 11 is a regular octagonal structure. A stirring barrel 41 is fixed on each of the four outer sides of the rotating frame 11. The stirring barrel 41 rotates with the rotating frame 11. A sealing cover 51 is provided on one side of each stirring barrel 41. The torsion spring 61 is installed on the sealing cover 51. The elastic force of the torsion spring 61 props the sealing cover 51 open and makes the upper port of the stirring barrel 41 in an open state. The driving plate 21 and the discharge plate 31 are both arranged on the rotation path of the sealing cover 51 rotating with the rotating frame 11.

[0024] When the sealing cover 51 contacts the driving plate 21 and moves in close proximity to the driving plate 21 , the driving plate 21 covers the sealing cover 51 on the mixing barrel 41 and closes the upper end of the mixing barrel 41 .

[0025] When the sealing cover 51 contacts the discharge plate 31 and moves in close contact with the discharge plate 31 , the discharge plate 31 props the sealing cover 51 open and opens the upper port of the mixing barrel 41 .

[0026] The sealing cover 51 in the present invention includes a cover body 511, a mounting plate 512, a support plate 513, a guide plate 514, a guide column 515, a spring 516, a limit column 517 and a roller 518. The mounting plate 512 and the support plate 513 are separated by a certain gap and are vertically fixed on the rotating frame 11. The mixing barrel 41 is placed between the mounting plate 512 and the support plate 513. The cover body 511 is rotatably connected to the top of the mounting plate 512 through an axle pin. The torsion spring 61 is sleeved on the axle pin, and the two free ends of the torsion spring 61 respectively abut against the cover body 511 and the mounting plate 512.

[0027] The guide plate 514 is fixed between the mounting plate 512 and the support plate 513, and the guide plate 514 is perpendicular to the support plate 513. The guide column 515 is elastically supported on the cover 511 by the spring 516, and the free end of the guide column 515 abuts against the guide plate 514. The limit column 517 is fixed on the guide plate 514, and the elastic force of the torsion spring 61 makes the cover 511 open and abut against the limit column 517, and the roller 518 is rotatably connected to the cover 511.

[0028] When the rotating frame 11 drives the sealing cover 51 to move together, when the roller 518 contacts the driving plate 21 and moves in close proximity to the driving plate 21, the driving plate 21 presses the sealing cover 51 and enables the sealing cover 51 to move against the elastic force of the torsion spring 61. During the closing process of the sealing cover 51, the guide column 515 moves in close proximity to the guide plate 514 to ensure the stability of the movement of the sealing cover 51.

[0029] After the sealing cover 51 completely covers the mixing barrel 41 and closes the upper end of the mixing barrel 41, the sealing cover 51 is pressed against the support plate 513. At this time, the lower end surface of the sealing cover 51 fits with the upper end surface of the mixing barrel 41 to ensure the sealing stability of the mixing barrel 41.

[0030] After the sealing cover 51 is completely covered on the mixing barrel 41 , the guide post 515 is just stuck in the guide plate 514 , thereby preventing the sealing cover 51 from being opened again due to the elastic force of the torsion spring 61 .

[0031] In order to better guide the guide column 515, an arc guide groove 5141 is provided on the guide plate 514, and a positioning through hole 5142 is provided at the bottom end of the arc guide groove 5141. When the roller 518 moves in contact with the driving plate 21 (i.e., during the closing process of the sealing cover 51), the guide column 515 moves along the arc guide groove 5141. When the sealing cover 51 is closed on the mixing barrel 41 (i.e., after the sealing cover 51 is completely closed on the mixing barrel 41), the guide column 515 passes through the positioning through hole 5142, thereby preventing the sealing cover 51 from being opened again due to the elastic force of the torsion spring 61.

[0032] The arc guide groove 5141 is arranged along the side of the guide plate 514, and the guide surface A where the arc guide groove 5141 contacts the guide column 515 is an inclined surface structure, and the inclination direction of the guide surface A is inclined outward from the positioning through hole 5142 at the bottom toward the top of the arc guide groove 5141. The positioning through hole 5142 is connected to the arc guide groove 5141, and the inner wall surface of the positioning through hole 5142 is a conical surface structure.

[0033] The inner wall surface of the positioning through hole 5142 is a conical structure, which can easily make the guide column 515 escape from the positioning through hole 5142. After the guide column 515 escapes from the positioning through hole 5142, the inclined surface structure of the arc guide groove 5141 can easily make the guide column 515 return to the original position under the elastic force of the torsion spring 61 and abut against the limit column 517.

[0034] In order to make the guide post 515 slide better in the arc guide groove 5141 , the end of the guide post 515 is a ball head structure.

[0035] In order to facilitate the installation of the guide column 515, the present invention has a guide tube 519 fixed on the cover body 511, the guide column 515 is inserted into the guide tube 519, a protrusion is provided on the guide column 515, and a spring 516 is sleeved on the guide column 515, and the top end of the spring 516 abuts against the protrusion, and the bottom end abuts against the inner wall of the guide tube 519.

[0036] The unloading plate 31 in the present invention is used to push the guide column 515 out of the positioning through hole 5142. The unloading plate 31 is arranged along the tangent direction of the rotation path of the rotating frame 11. A guide slope B is provided on the unloading plate 31. The guide column 515 moves along the guide slope B. The guide slope B enables the guide column 515 to overcome the elastic force of the spring 516 and enables the end of the guide column 515 to retract into the positioning through hole 5142. Under the elastic force of the torsion spring 61, the sealing cover 51 rebounds and enables the guide column 515 to move along the arc guide groove 5141.

[0037] The driving plate 21 in the present invention is used to cover the cover 511 on the mixing barrel 41 . The driving plate 21 is arranged along the tangent direction of the rotating path of the rotating frame 11 . A roller plate 211 is arranged on the driving plate 21 , and the roller 518 rolls along the roller plate 211 .

[0038] In the present invention, a stirring motor 411 is disposed on the outer wall of the stirring barrel 41 , a stirring shaft is disposed in the stirring barrel 41 , and an output shaft of the stirring motor 411 is fixedly connected to the stirring shaft.

[0039] The present invention has a simple structure, and the closing and opening actions of the sealing cover 51 on the mixing barrel 41 are realized through mechanical mutual linkage, avoiding the use of electric control and reducing the installation of electric control functional parts. The present invention is easy to maintain and has good use effect.

[0040] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
