[0026] Specifically, the intermittent mechanism 3 comprises a gear one 31, the surface of the movable rod 25 is provided with the gear one 31, the surface of the discharging box 21 is rotationally connected with a driving rod 32, the surface of the driving rod 32 is provided with a half gear 33, the half gear 33 is engaged with the gear one 31, thereby realizing intermittent movement of the driving rod 32, so that the material can be quantitatively discharged.

[0027] As shown in Figures 1 to 4 , the surface of the movable rod 25 is sleeved with a torsion spring 34, one end of the torsion spring 34 is connected with the discharging box 21, the other end of the torsion spring 34 is connected with the gear one 31, thereby realizing resetting of the movable rod 25, thereby facilitating use of the device.

[0028] Further, the inside of the discharging box 21 is provided with a driving motor 35, the output end of the driving motor 35 penetrates through the discharging box 21 and is connected with one end of the driving rod 32, thereby facilitating use of the operator.

[0029] It is worth noting that the conical discharging plate 23 is provided in a "conical structure" for guiding the material.

[0030] As shown in Figures 1 to 4As shown, the material guiding assembly 4 comprises a conical cylinder 41, the conical cylinder 41 is communicated with the discharging hole arranged on the surface of the quantitative disc 22, the conical cylinder 41 penetrates the discharging box 21 and extends to the inside of the discharging box 21 and is communicated with the feeding hole of the material guiding plate 42 arranged in the inside of the discharging box 21, the material guiding plate 42 penetrates the discharging box 21 and extends to the outside of the discharging box 21 and is aligned with the pressure plate of the tabletting mechanism 12, the material can drop in the inside of the material guiding plate 42 along the discharging hole arranged on the surface of the quantitative disc 22 and the conical cylinder 41, since the material guiding plate 42 is arranged in the "inclined shape", the material slides on the surface of the triangular plate 43 along the material guiding plate 42, then the material drops in the filling hole in the tabletting mechanism 12 along the triangular plate 43.

[0031] It is worth emphasizing that the discharging end of the discharging box 21 is provided with the triangular plate 43, the triangular plate 43 is located above the filling hole arranged on the surface of the pressure plate, so that the filling hole is conveniently filled with the material.

[0032] Wherein, the structure of the motor and the like is prior art, and will not be described in detail; meanwhile, the utility model further includes a power supply, a controller and a switch and the like, which are not the main technical points of the patent and will not be described in detail. The wiring diagram of the motor in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology, and its type is selected according to actual use, so the control mode and wiring arrangement of the motor will not be explained in detail.

[0033] The working principle and process are as follows: when the tabletting mechanism 12 on the processing table 1 is tabletted, the material to be made is first poured into the inside of the conical feeding plate 23. Since the blocking plate 24 blocks the discharge end of the conical feeding plate 23, the material cannot be discharged. At this time, the operator starts the driving motor 35, and the output end of the driving motor 35 drives the driving rod 32 to rotate. At this time, the driving rod 32 drives the half gear 33 to rotate, and since the half gear 33 is engaged with the gear one 31, the half gear 33 rotates continuously. At this time, the gear one 31 drives the movable rod 25 to rotate, and as the movable rod 25 continuously moves, the movable rod 25 drives the torsional spring 34 to deform. The torsional spring 34 can assist the movable rod 25 to reset. When the half gear 33 moves to a position without a rack, the gear one 31 is not engaged with the half gear 33. At this time, the torsional spring 34 drives the movable rod 25 to reset, so that the blocking plate 24 reblocks the discharge end of the conical feeding plate 23. As the half gear 33 continuously moves, the blocking plate 24 is intermittently reciprocated, thereby realizing intermittent discharging of the material in the conical feeding plate 23. In the process of rotating the rotating disc in the tabletting mechanism 12, the conical feeding plate 23 cannot be stopped in time, which causes the material to be discharged on the surface of the rotating disc in the tabletting mechanism 12, thereby causing waste of the material. When the filling hole is filled with material, the material is easily filled too much, so that the amount of material in each filling hole is not the same, thereby affecting the quality of the tabletted material.

[0034] When the discharge end of the conical feeding plate 23 is opened, the material falls into the inside of the quantitative disc 22 along the conical feeding plate 23. Then the material falls into the inside of the guide plate 42 through the discharge hole on the surface of the quantitative disc 22 and the conical cylinder 41. Since the guide plate 42 is arranged in an inclined shape, the material slides down the surface of the triangular plate 43 along the guide plate 42. Then the material falls into the filling hole in the tabletting mechanism 12 along the triangular plate 43.

[0035] When discharging, the operator moves the filling hole of the tabletting mechanism 12 below the triangular plate 43, thereby realizing filling of the filling hole.

[0036] It should be noted that the tabletting mechanism 12 in the device is the same as the principle of the disclosed patent with the application number CN202220101831.8, "rotary tablet press".

[0037] It is to be noted that, in the present document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
