Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical granule packaging machines, in particular to a feeding bin of a pharmaceutical granule packaging machine. Background Technique

[0002] In the modern pharmaceutical field, pharmaceutical granule packaging machines play a crucial role. Pharmaceutical granule packaging machines are used for precise and quantitative packaging operations of various pharmaceutical granules. However, there are often significant differences in the particle sizes of different pharmaceuticals, which puts higher requirements on the performance of the packaging machines.

[0003] The lower part of the feeding bin of the existing pharmaceutical granule packaging machine is equipped with a conical feeding port. Although this design helps the material to fall to a certain extent, since the angle of the conical feeding port cannot perfectly match the particle sizes of all materials, in actual operation, a series of problems often occur. During the feeding process of pharmaceutical granules, there are sometimes situations where the feeding is not smooth, resulting in a significant reduction in the efficiency of the entire packaging process. There will also be a phenomenon of uneven feeding, making the content of pharmaceutical granules in the package uneven, seriously affecting the quality and consistency of the product. In addition, some pharmaceutical granules will remain on the wall of the bin, not only causing waste of materials, but also potentially deteriorating due to long-term residue, posing a potential threat to the safety and effectiveness of the pharmaceuticals.

[0004] Particularly prominent is that the existing pharmaceutical granule packaging machines expose two key problems in actual applications. First, it is prone to clogging, especially when the material particle size is large or the humidity is high, and the clogging situation is more serious, greatly hindering the smooth progress of production. Second, it lacks accurate quantitative functions and cannot ensure that the content of pharmaceutical granules in each package can reach accurate and stable standards, which undoubtedly brings troubles and cost pressures to pharmaceutical enterprises. Content of the Utility Model

[0005] In order to solve the problems of unsmooth feeding of pharmaceutical granules, remaining on the wall of the bin, and quantitative discharging, the utility model provides a feeding bin of a pharmaceutical granule packaging machine, which includes a feeding port, a storage bin, and a vibrating feeding mechanism. The storage bin is fixedly arranged on the packaging machine. The feeding port is arranged on the upper side of the storage bin. The vibrating feeding mechanism is located on the lower side of the storage bin. A stirring mechanism is arranged on the storage bin.

[0006] Furthermore, the stirring mechanism includes a stirring blade group and a first motor. The stirring blade group is rotationally connected in the storage bin. The stirring blade group is arranged in layers in the vertical direction. A first motor for driving the stirring blade group is arranged at the top of the storage bin.

[0007] Further, the vibrating blanking mechanism includes a blanking component, which includes a first blanking pipe, a second blanking pipe, a vibrating spring group and a limiting plate.

The second blanking pipe is movably arranged in the circular hole of the limiting plate through a limiting spring.

[0008] Further, the vibrating blanking mechanism further includes a driving component, which includes a cam, a connecting rod and a second motor. The cam is rotatably connected to the lower side of the storage bin. A reset component is arranged on the lower side of the storage bin. One side of the connecting rod is always in contact with the circumferential side of the cam through the reset component. The other side of the connecting rod is in contact connection with the second blanking pipe along a direction perpendicular to the blanking direction. The second motor is fixedly arranged on the lower side of the storage bin, and the output shaft of the second motor is fixedly connected to the rotating shaft of the cam.

[0009] Further, the reset component includes a first limiting piece, a second limiting piece and a spring.

[0010] Further, the vibrating blanking mechanism further includes a quantitative control plate, which is arranged perpendicular to the discharging direction inside the second blanking pipe and is always in contact with the discharging nozzle of the first blanking pipe. There are holes arranged along the horizontal movement direction of the connecting rod between the side of the quantitative control plate close to the connecting rod and the inner wall of the second blanking pipe.

[0011] Further, a cavity is arranged between the second blanking pipe (312) and the first blanking pipe (311).

[0028] Referring to Figure 2 , the stirring mechanism 400 includes a stirring blade group 410 and a first motor 420. The stirring blade group 410 is rotatably connected inside the storage bin 100. The stirring blade group 410 is arranged in layers along the vertical direction. A first motor 420 for driving the stirring blade group 410 is arranged at the top of the storage bin 100.

[0029] During operation, the stirring blade group 410 is arranged in layers, enabling the medicine granules to be stirred in each layer, so that the medicine granules can be stirred more evenly. And due to the layered design, the medicine granules are not easily left on the wall of the storage bin 100, enabling the medicine granules to be mixed faster and more evenly, thus significantly improving the stirring efficiency, helping to eliminate the stirring dead corners, reducing the situation of remaining on the inner wall of the storage bin, and making the feeding process of the medicine granules smoother.

[0030] Referring to Figure 3 and Figure 4 , the vibrating feeding mechanism 300 includes a feeding component 310. The feeding component includes a first feeding pipe 311, a second feeding pipe 312, a vibrating spring group 313, and a limiting plate 314. The first feeding pipe 311 is nested in the second feeding pipe 312. A vibrating spring group 313 is arranged between the first feeding pipe 311 and the second feeding pipe 312 along the feeding direction. The second feeding pipe 312 is movably arranged in the circular hole of the limiting plate through a limiting spring.

[0031] Referring to Figure 4, the vibrating blanking mechanism 300 further includes a driving assembly 320. The driving assembly 320 includes a cam 321, a connecting rod 322, and a second motor 323. The cam 321 is rotatably connected to the lower side of the storage bin 100. A reset assembly 330 is provided on the lower side of the storage bin 100.

The connecting rod 322 passes through the second limit piece 332 and the spring 333, and the spring 333 is arranged between the first limit piece 331 and the second limit piece 332.

[0033] During operation, due to the characteristics of the cam 321, when the cam rotates, under the combined action of the connecting rod 322 and the reset assembly 330, the second blanking pipe will reciprocate to generate vibration, accelerating the flow of drug particles and not easily causing blockage at the second blanking pipe 312.

Referring to Figure 6 , at this time, the holes in the quantitative control plate 340 are aligned with the nozzle of the first blanking pipe 311, and the drug particles fall into the second blanking pipe 312 from the holes and fall into the packaging bag in cooperation with the vibration. A certain cavity is provided between the first blanking pipe 311 and the second blanking pipe 312 for temporarily storing the drugs. By adjusting the rotation speed of the cam 321. Referring to Figure 5, when the cam rotates to a certain position, before the holes of the control board 340 penetrate through the nozzle of the first blanking pipe 311 next time, all the drug particles in the cavity fall into the packaging bag, and there is time to complete the replacement of the next packaging bag. By coordinating the rotation period of the cam 321 and the time for replacing the packaging bag, the loading amount of a packaging bag can be controlled.

[0036] A slope along the blanking direction is provided at the bottom of the inner wall of the storage bin 100. After the blanking is completed, the equipment needs to be cleaned to facilitate the water in the storage bin to flow out.
