Description

Technical Field

[0001] The utility model belongs to the technical field of biopharmaceuticals, and in particular relates to a rotary tablet press. Background Art

[0002] A rotary tablet press is a device that compresses materials into tablets through rotational motion. It relies on the rotation of the rotary system to feed the material into the tableting mechanism. During the rotation process, the material is squeezed and compressed, and finally a tablet of the desired shape and size is formed.

[0003] The prior art discloses a rotary tablet press (CN219634616U), comprising a pressing unit, a molding unit, and a feeding unit. The pressing unit comprises a pressing disk and a pressing assembly disposed on the pressing disk. The pressing assembly comprises a first driver and a pressing mechanism connected to the first driver. The pressing mechanism comprises a mounting seat connected to the pressing disk and a pressing piece connected to the first driver. The mounting seat is provided with a receiving hole adapted for the pressing piece. The molding unit comprises a rotating base and a second driver disposed at the bottom of the rotating base. The rotating base is rotationally connected to the pressing disk via a connecting shaft. The second driver controls the rotation of the rotating base. The rotating base is provided with a plurality of molding grooves radially corresponding to the pressing mechanism. The feeding unit is used to feed material into one of the molding grooves. The rotary tablet press provided by the utility model aims to solve the problem that when preparing materials with high viscosity, the pressing head is easily adhered to the material, resulting in defects in the pressed product and a reduced service life of the pressing head.

[0004] After searching, it was found that the existing technology uses the edge of the feed seat to guide the tablets during discharge. This method lacks measures to clean the tablets during use. This results in the uncompacted powder being discharged along with the tablets during the process of the tablets stacking and falling on the table, causing excess powder to be inadvertently wasted, thereby increasing the loss of production costs. Moreover, since the device is not equipped with collection measures, the shaken powder cannot be collected, which easily causes dirt.

[0029] The working principle is as follows: the device sets a shaking structure and utilizes the eccentric rotation of the eccentric block 26 to adjust the up and down bouncing of the shaking block 24 and the shaking frame 30, so that the shaking block 24 drives the shaking frame 30 to bounce left and right. At this time, the tablets shake back and forth in the feeding shovel 22 to shake off the powder on the surface, and pass through the powder screening plate 25 to reach the collecting box 21. At this time, the tablets can be cleaned, avoiding inadvertent waste of powder and reducing production cost losses. By setting the powder screening plate 25, the powder cleaning brush 32 and the collecting box 21, the powder on the surface of the tablets is swept into the powder screening plate 25 by utilizing the cooperation between the powder cleaning brush 32, the shaking structure and the powder screening plate 25, and the powder is collected by the collecting box 21 to avoid waste caused by dirty powder.

[0030] like Figure 1 and Figure 2As shown, the bracket 10 is an E-shaped bracket, a placement slot 16 is provided in the bracket 10, a limit block 17 is fixedly connected to the inside of the bracket 10, the inner side of the limit block 17 is set to an arc surface, the arc surface corresponds to the curved surface of the electric rotating base 12, and a driver is installed on the bottom surface of the electric rotating base 12.

The support plates 18 are located directly below the placement slot 16 and the limit block 17, and the collection box 21 is slidably arranged between the two support plates 18.

[0031] The working principle is as follows. This device is designed on the basis of a rotary tablet press in the prior art (CN219634616U), in which the electric rotating base 12 used in the prior art is arranged below the pressing disk 13, and the electric rotating base 12 is rotatably connected to the pressing disk 13 by a connecting shaft, and the driver controls the rotation of the electric rotating base 12. When in use, the medicine powder in the hopper 14 enters the electric rotating base 12 through the feed pipe 11, and then is tableted through the cooperation of the pressing disk 13 and the electric rotating base 12. The tableted medicines are continuously accumulated below the feed pipe 11 through the rotation of the electric rotating base 12, and then fall into the unloading rack 19 at the limit block 17. Specifically, the connection relationship between the electric rotating base 12 and the pressing disk 13 has been disclosed in detail in a rotary tablet press in the prior art (CN219634616U), and will not be repeated again.

[0032] like Figure 2 、 Figure 4 and Figure 5 As shown, a powder screening plate 25 is fixedly connected between the two support plates 18, and the powder screening plate 25 is located above the collecting box 21. The powder screening plate 25 is an arc-shaped plate. A powder cleaning brush 32 is fixedly provided between the unloading rack 19 and the powder screening plate 25, and a shaking rack 30 is movably provided between the unloading rack 19 and the powder screening plate 25; Figure 2 and Figure 4 As shown, a sliding opening 20 is opened in the support plate 18, and the shaking frame 30 is a C-shaped square frame. A sliding post 31 is fixedly connected to each side of the shaking frame 30. The sliding post 31 slides in the sliding opening 20. A shaking spring 28 is fixedly provided between the shaking frame 30 and the support plate 18. The shaking frame 30 is elastically connected to the support plate 18 through the shaking spring 28; Figure 4As shown, two pillars 29 are symmetrically fixed inside the shaking frame 30, and two circular holes are symmetrically opened in the shaking block 24, which correspond to the pillars 29. Four buffer springs 27 are fixed between the shaking block 24 and the shaking frame 30. The four buffer springs 27 are symmetrically arranged on the upper and lower sides of the shaking block 24, and the shaking block 24 is elastically connected to the shaking frame 30 through the buffer springs 27; Figure 3 and Figure 4 As shown, one side of the shaking block 24 is fixedly connected to the motor box 15, and through holes are provided inside the shaking block 24 and the motor box 15.

The top surface of the shaking block 24 is fixedly connected to the feeding shovel 22, and the feeding shovel 22 is located above the shaking frame 30.

[0033] The specific implementation is as follows: a control switch of the motor 23 is installed on the outside of the motor box 15, and the start and stop of the motor 23 can be controlled by the control switch. Specifically, the medicine after tableting falls from the top surface of the limit block 17 to between the feeding shovel 22 and the powder screening plate 25, and the motor 23 is started. The motor 23 drives the shaft column and the eccentric block 26 to rotate. The centrifugal force generated by the rotation of the eccentric block 26 drives the shaking block 24 to slide up and down in the shaking frame 30 while squeezing the buffer spring 27 up and down to bounce up and down. The shaking block 24 will also move left and right synchronously while moving, prompting the shaking frame 30 to squeeze the shaking spring 28 to achieve left and right bouncing. At this time, the tablets move back and forth in the feeding shovel 22, and the powder on the surface can be shaken off. During the movement, since the feeding shovel 22 is tilted, the tablets will continue to slide between the powder cleaning brush 32 and the powder screening plate 25. After being cleaned by the powder cleaning brush 32, the powder passes through the powder screening plate 25 into the collecting box 21, and the tablets slide out from the surface of the powder screening plate 25.

[0034] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention.
