Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.
[0033] like Figures 1 to 7 As shown in the figure, in an embodiment of the utility model, a metering disk of a capsule filling machine comprises a metering disk upper die 1 and a metering disk lower die 2. The metering disk upper die 1 is circumferentially provided with a plurality of axially penetrating mounting holes 11, the mounting holes 11 are connected with a die hole sleeve 3, the center of the die hole sleeve 3 has an axially penetrating first die hole 31, the metering disk lower die 2 is correspondingly provided with an axially penetrating second die hole 21 corresponding to the mounting hole 11, and the lower end of the die hole sleeve 3 is located in the second die hole 21.
[0034] A second cavity 4 is formed between the bottom end of the first die hole 31 and the bottom end of the second die hole 21. The first die hole 31 and the second cavity 4 constitute a medicine filling cavity.
[0035] The die hole sleeve 3 axially slides in the second die hole 21 to adjust the volume of the second cavity 4 .
[0036] Through this arrangement, when the density of the medicine powder is different or the required filling weight standard changes, the height of the second cavity and the volume of the second cavity can be adjusted by adjusting the position of the die hole sleeve in the second die hole, thereby adjusting the volume of the medicine filling cavity to adapt to the change of the filling weight, thereby improving the flexibility of the application of the metering disk.
[0037] The metering plate lower die 2 is fixed on the filling rotating flange 5, and a mounting hole 12 is axially passed through the center of the metering plate upper die 1 and the metering plate lower die 2. A handle screw 6 is passed through the mounting hole 12. A threaded adjustment groove 51 is provided at the upper end of the filling rotating flange 5.
[0038] The lower end of the handle screw rod 6 passes through the threaded adjustment groove 51 to form a threaded connection therewith, and the upper end thereof passes through the mounting hole 12 to form a handle operating end 61.
[0039] A lifting linkage structure is provided between the upper die 1 of the metering disk and the handle screw 6 .
[0040] Through this arrangement, since the lower end of the handle screw is threadedly installed in the thread adjustment groove, and the upper mold of the metering disk and the handle screw have a lifting linkage relationship, when the handle operating end is rotated, the axial position of the handle operating end in the thread adjustment groove will change, thereby driving the height position of the upper mold of the metering disk and the mold hole sleeve connected to the upper mold of the metering disk to change, and finally realizing the adjustment of the volume of the medicine filling cavity.
[0041] The lifting linkage structure includes an abutment groove 13 located at the lower end center of the metering disc upper mold 1 and an abutment ring portion 62 arranged around the handle screw 6. The abutment ring portion 62 is located in the abutment groove 13 and its upper end surface abuts and cooperates with the upper end surface of the abutment groove 13.
[0042] Through this arrangement, quick disassembly and assembly between the handle screw and the upper die of the metering disk is achieved, and the linkage structure is stable and reliable.
[0043] A guide ring portion 22 whose shape matches that of the abutment groove 13 is disposed at the upper end of the metering disc lower die 2 . The guide ring portion 22 has a first guide groove 221 whose shape matches that of the abutment ring portion 62 .
[0044] Through this arrangement, a guiding fit is formed between the abutment groove and the guide ring portion, and between the abutment ring portion and the first guide groove, which limits the radial displacement of the upper mold of the metering disk during the lifting and lowering movement, and ensures the stability of the overall structure of the product.
[0045] The abutting ring portion 62 is provided with an elastic member 7 on its outer sleeve, and the two ends of the elastic member 7 abut against the upper end of the abutting groove 13 and the upper end of the lower die 2 of the metering disc, respectively.
[0046] The handle screw rod 6 is threadedly connected with a locking nut 8, and the lower end of the locking nut 8 abuts against the upper end surface of the metering plate upper mold 1.
[0047] Through this arrangement, in the installed state, the elastic part is compressed between the upper mold of the metering disk and the lower mold of the metering disk under the locking force of the threaded connection between the locking nut and the handle screw. The elastic part has an upward pre-tightening force on the upper mold of the metering disk, which can reduce the influence of the gravity of the upper mold of the metering disk on the wear of the connection between the handle screw and the threaded adjustment groove.
[0048] The upper periphery of the die hole sleeve 3 has a limiting convex portion 32 , and the upper end of the metering disc upper die 1 is correspondingly provided with the limiting convex portion 32 to form a matching limiting groove 14 , and the limiting groove 14 forms a lower limit for the limiting convex portion 32 .
[0049] This arrangement enables convenient assembly and disassembly between the die hole sleeve and the upper die of the metering disk.
[0050] The outer periphery of the limiting protrusion 32 is a conical surface with a diameter that decreases from top to bottom, and the limiting groove 14 is adapted in shape to the limiting protrusion 32 .
[0051] Through this arrangement, during the installation process, the conical surface has a guiding function and reduces the friction loss between the die hole sleeve and the upper die of the metering disk.
[0052] A guide boss 23 extends upward from the upper end of the metering disc lower die 2 , and a second guide groove 15 is correspondingly provided at the lower end of the metering disc upper die 1 to form a guiding match with the guide boss 23 .
[0053] This arrangement further improves the stability of the upper die of the metering plate during the lifting and lowering movement.
[0054] The outer circumference of the guide protrusion 23 includes a first conical surface 231 and a second cylindrical surface 232 connected from top to bottom. The diameter of the first conical surface 231 increases from top to bottom, and the diameter of the second cylindrical surface 232 is the same as the bottom diameter of the first conical surface 231.
[0055] Through this arrangement, the first conical surface has a guiding function, while reducing the friction loss between the first conical surface and the inner wall of the second guide groove.
[0056] The metering plate lower die 2 is fixedly mounted on the filling rotary flange 5 by means of a first bolt 9 .
[0057] This arrangement improves the convenience of disassembling and assembling between the metering plate lower die and the filling rotating flange.
[0058] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
